The Offer is being made in accordance with the requirements of the Irish Takeover Rules and pursuant to the US Exchange Act. This Offer Document, the Acceptance Documents and any other documents relating to the Offer have been or will be prepared in accordance with the Irish Takeover Rules and Irish disclosure requirements, format and style, all of which may differ from those in the United States.

The Offer is not being made, directly or indirectly, in or into or by the use of mails, or by any means or instrumentality (including, without limitation, email, facsimile transmission, telex and telephone) of interstate or foreign commerce, or of any facility of a national securities exchange, of any jurisdiction if to do so would constitute a violation of the relevant laws in such jurisdiction and, subject to certain exceptions, the Offer cannot be accepted by any such use, means, instrumentality or facility or from within any jurisdiction if to do so would constitute a violation of the relevant laws in such jurisdiction. Accordingly, copies of this Offer Document, the Acceptance Documents and any other accompanying documents are not being, and must not be, directly or indirectly, mailed or otherwise forwarded, distributed or sent, into or from any jurisdiction if to do so would constitute a violation of the relevant laws in such jurisdiction and persons receiving this Offer Document, the Acceptance Documents and any other accompanying documents (including custodians, nominees and trustees) must not mail or otherwise distribute or send them in, into or from such jurisdictions, as doing so may invalidate any purported acceptance of the Offer.

Any person (including, without limitation, any custodian, nominee or trustee) who intends to, or who may be under a contractual or legal obligation to, forward this Offer Document, the Acceptance Documents and/or any other related documentation to any jurisdiction outside Ireland and the United States should inform themselves of, and observe, any applicable legal or regulatory requirement of such jurisdictions. Further details in this regard are contained in paragraph 8 of Part 2 of Appendix 1.

This Offer Document does not constitute an offer to sell or invitation to purchase any securities, or the solicitation of any vote or approval in any jurisdiction pursuant to the Offer or otherwise, nor shall there be any sale, issuance or transfer of securities, in any jurisdiction in contravention of applicable law. In particular, this Offer Document is not an offer of securities for sale into the United States. No offer of securities shall be made in the United States absent an exemption from, or in a transaction not subject to, registration under the Securities Act of 1933, as amended. The release, publication or distribution of this Offer Document in certain jurisdictions may be restricted by law and therefore persons in such jurisdictions into which this Offer Document is released, published or distributed should inform themselves about and observe such restrictions. All offers of Topco Rollover Units (as defined herein) will be made pursuant to this Offer Document and an Offering Memorandum (as defined herein) to be distributed to Eligible MariaDB Shareholders (as defined herein) upon receipt of a completed properly completed Response Letter (as defined herein). Bidco, in its sole discretion, may determine if a MariaDB Shareholder is an Eligible MariaDB Shareholder pursuant to its review of the Response Letter.

This Offer Document (including any information incorporated by reference in this Offer Document), oral statements made regarding the Offer, and other information published by MariaDB, Bidco, K1 or any member of the K1 Group contain statements which are, or may be deemed to be, “forward looking statements.” Such forward looking statements are prospective in nature and are not based on historical facts, but rather on current expectations and on numerous assumptions regarding the business strategies and the environment in which any member of the K1 Group (including, after closing of the Offer, any member of the MariaDB Group) shall operate in the future and are subject to risks and uncertainties that could cause actual results to differ materially from those expressed or implied by those statements. The forward looking statements contained in this Offer Document relate to K1, any member of the K1 Group’s (including, after closing of the Offer, any member of the MariaDB Group) future prospects, developments and business strategies, the expected timing and scope of the Offer, the potential failure to satisfy conditions to the completion of the Offer due to the failure to receive a sufficient number of tendered MariaDB Shares in the Offer, the failure to obtain necessary regulatory or other approvals, the outcome of legal proceedings that may be instituted

against the K1 Group and/or others relating to the Offer; or, consistently the possibility that competing offers will be made; potential adverse reactions or changes to business relationships resulting from the announcement or completion of the Offer; significant or unexpected costs, charges or expenses resulting from the Offer; negative effects of this announcement or the consummation of the proposed acquisition on the market price of MariaDB’s Shares; and if the Offer is completed, potential failure to realize the expected benefits of the Offer and other statements other than historical facts. In some cases, these forward looking statements can be identified by the use of forward looking terminology, including the terms “believes,” “estimates,” “will look to,” “would look to,” “plans,” “prepares,” “anticipates,” “expects,” “is expected to,” “is subject to,” “intends,” “may,” “will,” “shall” or “should” or their negatives or other variations or comparable terminology. By their nature, forward looking statements involve risk and uncertainty because they relate to events and depend on circumstances that shall occur in the future. These events and circumstances include changes in global, political, economic, business, competitive, and market conditions and regulatory forces, future exchange and interest rates, changes in tax rates and future business combinations or disposals. If any one or more of these risks or uncertainties materialises or if any one or more of the assumptions prove incorrect, actual results may differ materially from those expected, estimated or projected. Such forward looking statements should therefore be construed in the light of such factors.

Neither K1, Bidco nor any member of the K1 Group, nor any of their respective associates or directors, officers or advisers, provides any representation, assurance or guarantee that the occurrence of the events expressed or implied in any forward looking statements in this Offer Document shall actually occur. Given these risks and uncertainties, shareholders, including those shareholders electing to receive the Unlisted Unit Alternative, should not place any reliance on forward looking statements. The forward looking statements speak only as of the date of this Offer Document. All subsequent oral or written forward looking statements attributable to any member of the K1 Group, or any of their respective associates, directors, officers, employees or advisers, are expressly qualified in their entirety by the cautionary statement above. K1 and the K1 Group expressly disclaim any obligation to update such statements other than as required by law or by the rules of any competent regulatory authority, whether as a result of new information, future events or otherwise.

Under the provisions of Rule 8.3 of the Irish Takeover Rules, if any person is, or becomes, interested (directly or indirectly) in 1% or more of any class of relevant securities of MariaDB, all “dealings” in any “relevant securities” of MariaDB (including by means of an option in respect of, or a derivative referenced to, any such “relevant securities”) must be publicly disclosed by not later than 3:30 p.m. (New York time) on the “business day” following the date of the relevant transaction. This requirement will continue until the date on which the Offer becomes or is declared unconditional as to acceptances or lapses or is otherwise withdrawn or on which the Offer Period otherwise ends. If two or more persons cooperate on the basis of any agreement, either express or tacit, either oral or written, to acquire an “interest” in “relevant securities” of MariaDB, they will be deemed to be a single person for the purpose of Rule 8.3 of the Irish Takeover Rules.

Under the provisions of Rule 8.1 of the Irish Takeover Rules, all “dealings” in “relevant securities” of MariaDB by MariaDB or Bidco, or by any of their respective “associates” must also be disclosed by no later than 12:00 p.m. (New York time) on the “business day” following the date of the relevant transaction.

A disclosure table, giving details of the companies in whose “relevant securities” “dealings” should be disclosed can be found on the Irish Takeover Panel's website at www.irishtakeoverpanel.ie.

“Interests in securities” arise, in summary, when a person has long economic exposure, whether conditional or absolute, to changes in the price of securities. In particular, a person will be treated as having an “interest” by virtue of the ownership or control of securities, or by virtue of any option in respect of, or derivative referenced to, securities.

Terms in quotation marks are defined in the Irish Takeover Rules, which can be found on the Irish Takeover Panel's website.

If you are in any doubt as to whether or not you are required to disclose a “dealing” under Rule 8, please consult the Irish Takeover Panel's website at www.irishtakeoverpanel.ie or contact the Irish Takeover Panel by telephone number +353 (0)1 678 9020; fax number +353 (0)1 678 9289.

No statement in this Offer Document is intended as a profit forecast or estimate for any period and no statement in this Offer Document should be interpreted to mean that earnings or earnings per share for K1, Bidco, Topco or MariaDB, respectively for the current or future financial years would necessarily match or exceed the historical published earnings or earnings per share for K1, Bidco, Topco or MariaDB, respectively. No statement in this Offer Document constitutes an asset valuation.

K1 and Bidco reserve the right, with the consent of the Irish Takeover Panel and MariaDB, to elect to implement the acquisition of the MariaDB Shares by way of a scheme of arrangement of MariaDB under the Companies Act 2014. In such event, the scheme of arrangement will be implemented on substantially the same terms, so far as applicable, as those which would apply to the Offer, subject to appropriate amendments (including to statutory voting requirements) to reflect the change in method of implementing the Offer.

This Offer Document, together with all information incorporated into this Offer Document by reference to another source, subject to certain restrictions relating to persons resident in Restricted Jurisdictions, will be made available on K1’s website (https://k1.com/meridian-offer-update/). Neither the content of any such website nor the content of any other website accessible from hyperlinks on such website is incorporated into, or forms part of, this Offer Document.

Any MariaDB Shareholder may request a copy of this Offer Document in hard copy form by contacting the Information Agent. Any written requests must include the identity of the MariaDB Shareholder and any hard copy documents will be posted to the address of the MariaDB Shareholder provided in the written request.

Such persons may also request that all future documents, announcements and information to be sent to them in relation to the offer should be in hard copy form.

Pursuant to Rule 14d-3 under the Exchange Act, Bidco has filed with the SEC a Tender Offer Statement on Schedule TO (as amended, the “Schedule TO”), of which this Offer Document forms a part, and exhibits to the Schedule TO. The Schedule TO and the exhibits thereto, as well as other information filed by Bidco with the SEC, are available on the SEC website at www.sec.gov. Additional copies of this Offer Document, the related Letter of Transmittal and other materials related to the Offer may also be obtained for free from the Information Agent.

Certain figures included in this Offer Document have been subjected to rounding adjustments. Accordingly, any figures shown for the same category presented in different tables may vary slightly and figures shown as totals in certain tables may not be an arithmetic aggregation of the figures that precede them.

If you wish to tender all or (in the case of a tender for the Cash Offer only) a portion of your MariaDB Shares to Bidco in the Offer, you must do the following:

We are not providing for guaranteed delivery procedures. Therefore, MariaDB Shareholders must allow sufficient time for the necessary tender procedures to be completed during normal business hours of DTC.

Eligible MariaDB Shareholders that wish to receive the Unlisted Unit Alternative will also be required to provide a completed Response Letter to the Investor Questionnaire as further described in Part 3 of Appendix 1. Bidco will review all Response Letters upon receipt, and this review process will take time. Eligible MariaDB Shareholders that wish to receive the Unlisted Unit Alternative are strongly encouraged to return their Letter of Transmittal (or, in the case of a book-entry transfer, an Agent’s Message in lieu of a Letter of Transmittal) electing for the Unlisted Unit Alternative as soon as possible.

Upon completion of the Response Letter and a determination by Bidco, in its sole discretion, that such MariaDB Shareholder may be offered and sold Topco Rollover Units pursuant to an exemption from registration under the Securities Act and an exemption from the registration requirements of applicable US state securities laws, such Eligible MariaDB Shareholder will receive a confidential offering memorandum (the “Offering Memorandum”). In addition, Eligible MariaDB Shareholders that wish to receive the Unlisted Unit Alternative will be required, following completion of the Response Letter and subsequent receipt of the Offering Memorandum, to deliver a signature page to the Topco LLCA to complete their election for the Unlisted Unit Alternative as further described in Part 3 of Appendix 1. Failure to complete these additional requirements will result in the relevant Eligible MariaDB Shareholders that tender their MariaDB Shares for the Unlisted Unit Alternative being unable to receive the Topco Rollover Units.

Questions or requests for assistance may be directed to Georgeson LLC, the Information Agent for the Offer, at the address and telephone number set forth in this Offer Document. Additional copies of this Offer Document, the related Letter of Transmittal and other materials related to the Offer may be obtained at no cost to MariaDB Shareholders from the Information Agent. Additionally, copies of this Offer Document, the related Letter of Transmittal and any other materials related to the Offer are available free of charge at www.sec.gov.

For legal reasons, the Information Agent’s contact numbers listed at the front of this Offer Document will only be available to assist you with information contained in this Offer Document. Advice on the merits of the Offer cannot be provided nor may any financial advice be given. Calls may be monitored for quality control purposes.

This Offer Document and the related Letter of Transmittal contain important information, and you should read both carefully and in their entirety before making a decision with respect to the Offer.

The following are some of the questions you, as a holder of MariaDB Shares, may have and answers to those questions. You are advised to read carefully the remainder of this Offer Document and all of the Appendices referred to herein, plus the accompanying Acceptance Documents.

Under the terms of the Offer, which is subject to the satisfaction (or where applicable, waiver) of the conditions and further terms set out in Appendix 1 to this Offer Document and in the Letter of Transmittal, MariaDB Shareholders will be entitled to receive:

for each MariaDB Share: US$0.55 in cash

or, as an alternative to the Cash Offer, MariaDB Shareholders may elect to receive the Unlisted Unit Alternative on the following basis:

for each MariaDB Share: 1 Topco Rollover Unit

in lieu of the Cash Offer consideration to which they would otherwise be entitled under the Offer, subject to the proration provisions described at question 8 below and in further detail in paragraph 7 of Part 2 of Appendix 1.

The Topco Rollover Units will be issued on the terms and pursuant to the mechanism described in paragraph 7 of Part 2 of Appendix 1 and the Offering Memorandum. MariaDB Shareholders can elect to accept either the Cash Offer or the Unlisted Unit Alternative, but not both or a mixture of both.

The Offer is being made by Bidco. Bidco was formed under the laws of Delaware, USA, and established specifically for the purpose of making the Offer. Further details in relation to Bidco and the financing of the Offer are described in Appendix 5.

Bidco is seeking to acquire all of the issued and to be issued MariaDB Shares. According to MariaDB, there were 69,025,648 MariaDB Shares outstanding as of 16 May 2024 (being the latest practicable date).

In aggregate, the maximum number of Topco Rollover Units available to be issued to Eligible MariaDB Shareholders under the Unlisted Unit Alternative is limited to 15% of Topco's fully diluted share capital (after issuance of all Topco Rollover Units to all Electing Shareholders) (the “Rollover Threshold”), equal to 39,729,622 Topco Rollover Units. Electing Shareholders may be subject to proration, as described in paragraph 7.4 of Part 2 of Appendix 1.

The Topco Rollover Units will not be listed or registered under US securities laws, will not be transferable (subject to certain limited exceptions), will be non-voting (other than those non-waivable voting rights, if any, required pursuant to applicable Delaware law), will have limited information rights (except for certain limited information to be provided to holders of the Topco Rollover Units and certain other financial information regarding Topco as the holders of Topco Rollover Units may reasonably request in writing from time to time (but no more frequently than annually)), and may be subject to dilution pursuant to any further issue of securities by Topco.

The Cash Offer of US$0.55 represents a premium of approximately:

Lazard Frères has provided an estimate of the value of a Topco Rollover Unit as required by Rule 24.11 of the Irish Takeover Rules. This estimate is set out in a letter included at Appendix 3 to this Offer Document.

No. If the aggregate number of Topco Rollover Units to be issued to all Electing Shareholders exceeds the Rollover Threshold then each Electing Shareholder’s number of Topco Rollover Units to which they would otherwise have been entitled will be reduced on a pro-rated basis (based on the relative holdings of all of the Electing Shareholders of MariaDB Shares as of immediately prior to the Closing Date), and the consideration for each MariaDB Share that is not exchanged for Topco Rollover Units will be paid in cash in accordance with the terms of the Cash Offer as described in Part 2 of Appendix 1.

Bidco may in its sole discretion, withdraw the Unlisted Unit Alternative if there are any Electing Shareholders whose election to receive the Unlisted Unit Alternative will require registration of the Topco Rollover Units under US securities law (and there is not an applicable exemption for each such Electing Shareholder) (the “Rollover Withdrawal Right”). In the event Bidco exercises its Rollover Withdrawal Right, the Unlisted Unit Alternative will lapse, no Topco Rollover Units will be issued and the consideration payable in respect of each tendered MariaDB Share will be settled in cash in accordance with the terms of the Cash Offer. The Offer will be open for at least 10 Business Days after the announcement of Bidco’s exercise of its Rollover Withdrawal Right. For the avoidance of doubt, the exercise by Bidco of the Rollover Withdrawal Right shall not otherwise affect any validly received tenders, nor shall it constitute a variation of the Offer under the Irish Takeover Rules. In the event Bidco exercises its Rollover Withdrawal Right, all elections for the Unlisted Unit Alternative will be deemed elections for the Cash Offer.

In addition, Eligible MariaDB Shareholders that wish to receive the Unlisted Unit Alternative will be required to (i) provide a completed Response Letter and (ii) following receipt of the Offering Memorandum (if applicable), a signature page to the Topco LLCA by the Expiration Time, as further described in Part 3 of Appendix 1. Failure to complete these additional requirements will result in the relevant Eligible MariaDB Shareholders that tender their MariaDB Shares being unable to receive the Unlisted Unit Alternative.

Promptly after the Expiration Time, Bidco will accept all MariaDB Shares validly tendered and not properly withdrawn prior to the Expiration Time. Rule 14e-1(c) under the US Exchange Act requires that an offeror in a tender offer either pay the consideration offered or return the securities tendered “promptly” after the withdrawal or termination of the tender offer, and as a result the Closing Date will be no later than three Business Days following the expiration date of the Offer. For further information in relation to the conditions to the Offer, please refer to Part 1 of Appendix 1.

Where cash consideration is payable in respect of your tendered MariaDB Shares, Bidco will deliver the cash consideration for your validly tendered and not properly withdrawn MariaDB Shares by depositing the cash with the Exchange Agent, which will act as your agent for the purpose of receiving the Offer consideration from Bidco and transmitting such consideration to you. Where Topco Rollover Units are deliverable in respect of your tendered MariaDB Shares, physical certificates representing Topco Rollover Units will not be issued pursuant to the Unlisted Unit Alternative. Rather, each Electing Shareholder’s name will be entered on the Unit ownership ledger of Topco in respect of the Topco Rollover Units to which such Electing Shareholder becomes entitled pursuant to the Unlisted Unit Alternative.

The MariaDB Board has, as required under the Irish Takeover Rules, due to conflicts of interest, recused itself from taking part in the formulation and communication of advice on the Offer to MariaDB Shareholders. Instead, IBI Corporate Finance, which has been appointed as independent financial advisor to MariaDB under Rule 3 of the Irish Takeover Rules, has, in that capacity, taken responsibility for considering the Offer and formulating an appropriate recommendation to be made to MariaDB Shareholders.

As described in the Firm Announcement and as is expected to be described in the First Response Circular/Schedule 14D-9, IBI Corporate Finance has concluded, in the context of the background to and reasons for recommending the Cash Offer set out therein that the terms of the Cash Offer are fair and reasonable and it would recommend that MariaDB Shareholders should accept the Cash Offer.

IBI Corporate Finance has stated that it is unable to advise as to whether or not the financial terms of the Unlisted Unit Alternative are fair and reasonable. This is because IBI Corporate Finance has not had any involvement in the development and validation of any financial projections for Topco. As a result, IBI Corporate Finance is unable to assess any plans Topco may have for the development of MariaDB or the Topco Group to the degree necessary to form an assessment of the value of the Unlisted Unit Alternative.

A description of the reasons for IBI Corporate Finance’s approval of the Cash Offer is set forth in the First Response Circular/Schedule 14D-9. All shareholders should carefully read the information set forth in the First Response Circular/Schedule 14D-9.

As further defined in Part 1 of Appendix 1 of this Offer Document, the Offer is conditional on valid acceptances being received by Bidco (and not being withdrawn) by not later than the Acceptance Cut-off Time (or such later time(s) and/or date(s) as Bidco may: (i) with the consent of the Irish Takeover Panel (to the extent required) or in accordance with the Irish Takeover Rules; and (ii) subject to the US tender offer rules, determine) in respect of MariaDB Shares Affected representing not less than 80% (or such lower percentage as Bidco may decide) in nominal value of the Maximum MariaDB Shares Affected, which carry, or if allotted and issued, or reissued from treasury would carry, not less than 80% (or such lower percentage as Bidco may decide) of the voting rights attaching to the Maximum MariaDB Shares Affected. This percentage may be reduced at the discretion of Bidco, subject to certain limitations.

If the Acceptance Condition is met at the Acceptance Unconditional Time (as it may be extended as described herein), Bidco will be required to close the Offer regardless of whether the Acceptance Condition is no longer met at the Expiration Time. This obligation will continue regardless of whether Bidco is no longer in a position to carry out the Buy Out.

MariaDB Shareholders who have accepted should withdraw their acceptances if their willingness to accept the Offer would be affected by the reduction of the Acceptance Condition or by Bidco’s potential inability to carry out the Buy Out.

The Offer is conditional on no regulatory body having decided to take any action or institute any investigation or enquiry or having done or decided to do anything, in each case which would or would reasonably be expected to:

K1 expects that the Offer will be reviewed by one or more regulators once the Offer Document is sent to MariaDB Shareholders. The timing and outcome of such review(s) is currently unknown.

In addition, there are anti-trust/competition law conditions and a condition that MariaDB takes no frustrating actions (within the meaning of Rule 21 of the Irish Takeover Rules), among others. The Irish Takeover Rules require us to obtain the consent of the Irish Takeover Panel before Bidco can invoke any condition to the Offer involving a criterion of materiality. In practice, the Irish Takeover Panel is unlikely to give such consent unless the circumstances underlying the failure of the condition are of material significance to Bidco in the context of the Offer.

The full text of all of the conditions to the Offer is set out in Part 1 of Appendix 1.

The intention of the Acceptance Unconditional Time, and the Post-Acceptance Unconditional Period, is to announce to MariaDB Shareholders that the Acceptance Condition has been met, and that the MariaDB Shares tendered at the Expiration Time will be accepted for exchange. For the avoidance of doubt, Bidco is not required to declare the Offer unconditional as to acceptances until it is satisfied that all other Conditions will be satisfied or waived at the Expiration Time.

Bidco may only take into account acceptances received up to the Acceptance Cut-off Time for the purposes of testing if the Acceptance Condition has been satisfied. Bidco will publicly announce, as set forth in paragraph 3.1 of Part 2 of Appendix 1, the occurrence of the Acceptance Unconditional Time.

This gives MariaDB Shareholders who have not yet tendered the opportunity to do so knowing that the Offer will close, and that if they do not tender they are likely to be subject to the application of the provisions of Sections 456 to 460 of the Companies Act 2014 and the compulsorily acquisition of their MariaDB Shares.

So long as the Offer is declared unconditional as to acceptances at the Acceptance Unconditional Time (as it may be extended as described herein), if acceptances fall below the Acceptance Condition (as it may have been amended or waived, to the extent permitted, on or prior to the Acceptance Unconditional Time) due to withdrawals during the Post-Acceptance Unconditional Period, Bidco will still be required to close the Offer as of the Expiration Time (as it may be extended as described herein). If Bidco declares the Offer to be unconditional as to acceptances, it will deem all remaining Conditions to be satisfied or waived at the Expiration Time. Once the Offer has been declared unconditional as to acceptances, Bidco will be required to close the Offer regardless of whether there are withdrawals during the Post-Acceptance Unconditional Period, through and including the Expiration Time, and regardless of whether Bidco is able to carry out the compulsory acquisition process referenced in the preceding paragraph.

While you have until the Expiration Time to complete your tender, if Bidco cannot determine at the Acceptance Unconditional Time (as it may be extended to no later than the Acceptance Condition Outside Time or otherwise with the consent of the Irish Takeover Panel) that (i) the Acceptance Condition has been satisfied, fulfilled or, to the extent permitted, waived, and (ii) all other Conditions will be satisfied, fulfilled or, to the extent permitted, waived by the Expiration Time, the Offer will lapse and there will be no Post-Acceptance Unconditional Period. Therefore, MariaDB Shareholders are strongly encouraged to tender their MariaDB Shares as soon as possible and prior to the Acceptance Cut-off Time.

In the event the Offer lapses, all MariaDB Shares that have tendered their MariaDB Shares at that time will be returned (together with share certificates where applicable) (by post or such other method as may be approved by the Irish Takeover Panel), without expense to the tendering shareholder (or, in the case of MariaDB Shares tendered by book-entry transfer into the Exchange Agent’s account at a Book-Entry Transfer Facility, such MariaDB Shares will be credited to an account maintained at such Book-Entry Transfer Facility), as soon as practicable and in any event within three Business Days following the lapse of the Offer.

The Acceptance Unconditional Time may be extended to any date up to the Acceptance Condition Outside Time at the discretion of Bidco, to provide additional time for the Acceptance Condition to be satisfied, fulfilled or, to the extent permitted, waived. Any additional extension beyond the Acceptance Condition Outside Time would require the consent of the Irish Takeover Panel. If the Acceptance Unconditional Time is extended, the Expiration Time of the Offer will also be extended for the same number of days such that the Post-Acceptance Unconditional Period runs for at least fourteen calendar days following the Acceptance Unconditional Time. If the Acceptance Unconditional Time is extended, the Acceptance Cut-off Time will be similarly extended.

Bidco must be satisfied that the Conditions (other than the Acceptance Condition) will be satisfied, fulfilled or, to the extent permitted, waived at the Expiration Time (as it may be extended as described herein) before Bidco will declare the Offer unconditional as to acceptances.

So long as the Offer is declared unconditional as to acceptances at the Acceptance Unconditional Time (as it may be extended as described herein), Bidco will deem all remaining Conditions to be satisfied, fulfilled or, to the extent permitted, waived at the Expiration Time and will be required to close the Offer.

In the event of the Offer lapsing, all MariaDB Shares that have been tendered at that time will be returned (together with the relevant share certificates if applicable) (by post or such other method as may be approved by the Irish Takeover Panel), without expense to the tendering shareholder (or, in the case of MariaDB Shares tendered by book-entry transfer into the Exchange Agent’s account at a Book-Entry Transfer Facility, such MariaDB Shares will be credited to an account maintained at such Book-Entry Transfer Facility), as soon as practicable and in any event within three Business Days following the lapse of the Offer.

Under the Irish Takeover Rules, the Acceptance Condition must be satisfied by the Acceptance Condition Outside Time, unless that time is extended with the consent of the Irish Takeover Panel. Under the Irish Takeover Rules, Bidco must satisfy the remaining Conditions within a further twenty-one calendar days of the Acceptance Condition Outside Time, unless extended with the consent of the Irish Takeover Panel. As a result of a derogation granted by the Irish Takeover Panel, Bidco is not required to declare that the Acceptance Condition has been satisfied, until Bidco is satisfied that the other Conditions will be satisfied, fulfilled or, to the extent permitted, waived by the Expiration Time.

Once Bidco has made that determination, it will declare that the Acceptance Condition has been satisfied and will simultaneously declare that the remaining Conditions will be deemed to be satisfied, fulfilled or, to the extent permitted, waived at the Expiration Time (as it may be extended as described herein). Under the Irish Takeover Rules, once the Acceptance Condition has been satisfied, shareholders must be provided with at least an additional fourteen days to accept the Offer, which fourteen-day period is expected to expire at the Expiration Time (as it may be extended as described herein). MariaDB Shareholders will have withdrawal rights during this additional fourteen-day period. This fourteen-day period must elapse before the Offer can be closed.

The Post-Acceptance Unconditional Period will begin once the Offer has been declared unconditional as to acceptances. The Offer will be declared unconditional as to acceptances if at the Acceptance Unconditional Time Bidco can determine (i) that the Acceptance Condition has been satisfied, fulfilled or, to the extent permitted, waived; and (ii) the Conditions (other than the Acceptance Condition) will be satisfied, fulfilled or, to the extent permitted, waived at the Expiration Time (as it may be extended as described herein). Bidco cannot acquire your MariaDB Shares pursuant to the Offer unless the Offer becomes or is declared unconditional as to acceptances by the Acceptance Unconditional Outside Time, absent approval from the Takeover Panel.

During the Post-Acceptance Unconditional Period, Bidco will have at least fourteen calendar days, but no more than twenty one calendar days, absent approval from the Takeover Panel, to declare the Offer unconditional in all respects. Withdrawal rights will continue for the duration of the Post-Acceptance Unconditional Period.

So long as the Offer is declared unconditional as to acceptances at the Acceptance Unconditional Time (as it may be extended as described herein), if acceptances fall below the Acceptance Condition (as it may have been amended or waived, to the extent permitted, on or prior to the Acceptance Unconditional Time) due to withdrawals during the Post-Acceptance Unconditional Period, Bidco will still be required to close the Offer as of the Expiration Time (as it may be extended as described herein). If Bidco declares the Offer to be unconditional as to acceptances, it will deem all remaining Conditions to be satisfied or waived at the Expiration Time. Once the Offer has been declared unconditional as to acceptances, Bidco will be required to close the Offer regardless of whether there are withdrawals during the Post-Acceptance Unconditional Period, through and including the Expiration Time, and regardless of whether Bidco is able to carry out the Buy Out. For the avoidance of doubt, Bidco is not required to declare the Offer unconditional as to acceptances until it is satisfied that all other Conditions will be satisfied or waived at the Expiration Time.

As such, Bidco and K1 cannot guarantee that it will control MariaDB after the close of the Offer as the number of withdrawals during the Post Acceptance Unconditional Period may be such that Bidco may not have received sufficient acceptances at the Expiration Time to acquire control of MariaDB (e.g. 50%+ of the issued share capital of MariaDB). However, the K1 Group has received irrevocable undertakings to accept the Offer, or, where Bidco and/or the K1 Group elects to switch to a scheme of arrangement with respect to MariaDB under the Companies Act 2014, vote in favour of the scheme of arrangement under the Companies Act 2014, in respect of, in aggregate, 47,402,907 MariaDB Shares, representing in aggregate approximately 68.67% of the existing issued share capital of MariaDB as of 16 May 2024. The details of such irrevocable undertakings are set out in paragraph 6 “Disclosable Transactions” of the “Special Factors” section of this Offer Document. Notwithstanding the Offer being declared unconditional as to acceptances, Bidco and K1 also cannot guarantee that it will be in a position to carry out the Buy Out, including because the number of withdrawals during the Post Acceptance Unconditional Period may be such that Bidco may not have received sufficient acceptances at the Expiration Time to carry out the Buy Out under the provisions of Sections 456 to 460 of the Companies Act 2014.

If the Rollover Withdrawal Right is exercised during the Post-Acceptance Unconditional Period, the Offer will remain open for at least ten Business Days following announcement of the change in consideration offered. If this occurs more than seven calendar days following the first day of the Post-Acceptance Unconditional Period, the consent of the Irish Takeover Panel will be required to permit compliance with Rule 14e-1(c) of the U.S. Exchange Act.

The last day on which the Offer could become or be declared unconditional in all respects is the Expiration Time, which may be extended until the twenty first day following the start of the Post-Acceptance Unconditional Period, unless the Irish Takeover Panel agrees to a further extension of the Post-Acceptance Unconditional Period.

No. The Offer is not subject to a financing condition. The Offer is being financed through existing resources of K5, as described in paragraph 8 of the Letter from the President of Bidco.

Please refer to paragraph 13 of the Letter from the President of Bidco and Part 3 of Appendix 1 of this Offer Document for instructions on how to accept the Offer.

You will have until the Expiration Time (as it may be extended as described herein) to accept the Offer. We refer to this period, including any extensions, as the Offer Period. You may accept the Offer and withdraw any previous acceptances during the Offer Period.

However, while you have until the Expiration Time to complete your tender, if Bidco cannot determine at the Acceptance Unconditional Time (as it may be extended as described herein) that (i) the Acceptance Condition has been satisfied, fulfilled or, to the extent permitted, waived, and (ii) all other conditions will be satisfied, fulfilled or, to the extent permitted, waived by the Expiration Time, the Offer will lapse and there will be no Post-Acceptance Unconditional Period. Therefore, MariaDB Shareholders are strongly encouraged to tender their MariaDB Shares as soon as possible and prior to the Acceptance Cut-off Time.

Bidco may extend the Offer Period at any time in its discretion, provided (i) the Pre-Acceptance Unconditional Period may not extend past the Acceptance Condition Outside Time and (ii) the Post-Acceptance Unconditional Period may not be longer than twenty one calendar days, in each case without the consent of the Irish Takeover Panel.

Bidco may also be required to extend the Offer Period under applicable securities laws if it changes the Offer in any material respect. The minimum period during which the Offer must remain open following material changes in the terms of the Offer will depend upon the facts and circumstances then existing, including the materiality of the changes.

Please refer to paragraph 1 of Part 2 of Appendix 1 for more information.

If Bidco extends the Acceptance Unconditional Time and/or the Expiration Time, it will make a public announcement of the extension not later than 8:00 a.m. (New York City time) on the next Business Day following the date on which the Offer is extended.

Please refer to paragraph 3 of Part 2 of Appendix 1 for more information.

Yes. To withdraw an acceptance, you must deliver a written notice of withdrawal with the required information to the Exchange Agent as applicable, at any time during the Offer Period.

Please refer to paragraph 4 of Part 2 of Appendix 1 for more information.

If elections for the Unlisted Unit Alternative by Electing Shareholders result in the issuance of fewer Units than the Rollover Threshold and to the extent Bidco’s exercise of the Rollover Withdrawal Right does not occur, then, following the Closing Date, each Electing Shareholder, and only Electing Shareholders, will be offered the opportunity to subscribe in cash, at a value of US$0.55 per Topco Rollover Unit, after completion of the Offer for such number of additional Topco Rollover Units as shall equal the following: (i) the number of Topco Rollover Units equal to the Rollover Threshold minus (ii) the number of Topco Rollover Units issued to Electing Shareholders who elected to receive the Unlisted Unit Alternative in the Offer (the result of such calculation, the “Available Excess,” such further subscription opportunity, the “Top Up,” and the Electing Shareholders participating in the Top Up the “Top Up Electing Shareholders”); provided that, for clarity, in no event shall the aggregate issuance of Topco Rollover Units to all Electing Shareholders (including Top Up Electing Shareholders), including in the Top Up, exceed the Rollover Threshold. In the event that, in the Top Up, the aggregate subscriptions of Top Up Electing Shareholders exceed the Available Excess, then (a) such subscriptions will be subject to pro-ration based on the relative holdings of MariaDB Shares as of immediately prior to the Closing Date of the Top Up Electing Shareholders; and (b) any fractional entitlements to Topco Rollover Units under the Top Up will be rounded down to the nearest whole number of Topco Rollover Units per Top Up Electing Shareholder.

If the Offer becomes or is declared unconditional in all respects and sufficient acceptances have been received at the Expiration Time (and in all cases within four months of the date of this document), following closing of the Offer, Bidco intends to apply the provisions of Sections 456 to 460 of the Companies Act 2014 to acquire compulsorily any outstanding MariaDB Shares not acquired or agreed to be acquired pursuant to the Offer or otherwise. The default election for all MariaDB Shareholders during this compulsory acquisition process will be for the Cash Offer. Furthermore, if Bidco has exercised its Rollover Withdrawal Right, the Unlisted Unit Alternative will not be available to any MariaDB Shareholders during this compulsory acquisition process and each remaining MariaDB Shareholder will be deemed to have elected for the Cash Offer.

The latest date by which Bidco may serve notice to apply the provisions of Sections 456 to 460 of the Companies Act 2014 is six months from the date of this Offer Document.

Notwithstanding the Offer being declared unconditional as to acceptances, Bidco and K1 also cannot guarantee that it will be in a position to carry out the Buy Out, including because the number of withdrawals during the Post Acceptance Unconditional Period may be such that Bidco may not have received sufficient acceptances at the Expiration Time to carry out the Buy Out under the provisions of Sections 456 to 460 of the Companies Act 2014. In addition, Bidco and K1 cannot guarantee that it will control MariaDB after the close of the Offer as the number of withdrawals during the Post Acceptance Unconditional Period may be such that Bidco may not have received sufficient acceptances at the Expiration Time to acquire control of MariaDB (e.g. 50%+ of the issued share capital of MariaDB). However, the K1 Group has received irrevocable undertakings to accept the Offer, or, where Bidco and/or the K1 Group elects to switch to a scheme of arrangement with respect to MariaDB under the Companies Act 2014, vote in favour of the scheme of arrangement under the Companies Act 2014, in respect of, in aggregate, 47,402,907 MariaDB Shares, representing in aggregate approximately 68.67% of the existing issued share capital of MariaDB as of 16 May 2024. The details of such irrevocable undertakings are set out in paragraph 6 “Disclosable Transactions” of the “Special Factors” section of this Offer Document.

After the Offer has closed and as soon as it is appropriate and possible to do so, Bidco intends to cause MariaDB to apply for cancellation of the listing of the MariaDB Shares on the NYSE, and to propose a resolution to re-register MariaDB as a private company under the relevant provisions of the Companies Act 2014. De-listing is likely to reduce significantly the liquidity and marketability of any MariaDB Shares in respect of which the Offer has not been accepted. Following the delisting of the MariaDB Shares from the NYSE, Bidco intends to procure that MariaDB files with the SEC a request that MariaDB’s obligations under the US Exchange Act be terminated if and when MariaDB is eligible to do so.

The cash consideration payable under the Offer will be settled in US dollars. It will not be possible to choose an alternative currency in which to receive the cash consideration payable under the Offer.

If you are the registered owner of your MariaDB Shares and you accept the Offer, you will not have to pay brokerage fees or similar expenses in connection with your acceptance of the Offer. If you own your MariaDB Shares through a broker or other securities intermediary, and your securities intermediary accepts the Offer on your behalf, your securities intermediary may charge you a fee for doing so. You should consult your broker or securities intermediary to determine whether any charges will apply.

A MariaDB Shareholder who is not resident or ordinarily resident or temporarily non-resident in Ireland, and who does not hold the MariaDB Shares in connection with a trade or business carried on in Ireland through a branch or agency, should not be subject to Irish tax on the consideration they receive in respect of the Offer. Other MariaDB Shareholders may have a liability to Irish tax.

For US federal income tax purposes, there will be tax consequences arising in connection with your sale of MariaDB Shares in the Offer. How you will be taxed will depend on a number of factors including, but not limited to, when you acquired the MariaDB Shares and if such MariaDB Shares were acquired pursuant to the exercise of a stock option. The tax implications of participating in the Offer are complex.

Important tax information related to the potential US federal income tax consequences of participation in the Offer is set forth in Section 1.2 (US Federal Income Tax) of Appendix 6. You should consult with your own legal, investment and tax advisors to determine the potential benefits, burdens and other consequences of the Offer particular to you, including the US federal, state, local, non-US and other tax consequences of participating in the Offer.

The above is provided for general information only. For an outline of the material Irish and US federal income tax consequences of the Offer, please see Appendix 6. It is recommended that you consult an appropriate independent adviser in respect of your tax treatment in relation to the Offer.

NONE OF BIDCO OR MARIADB ARE PROVIDING ANY TAX ADVICE, OR GUARANTEEING ANY TAX CONSEQUENCES FOR PARTICIPATION IN THIS OFFER DOCUMENT, AND YOU SHOULD CONSULT WITH YOUR OWN TAX ADVISOR TO DETERMINE THE TAX CONSEQUENCES OF YOUR PARTICULAR SALE OF ELIGIBLE SHARES TO BIDCO IN, AND IN ACCORDANCE WITH THE TERMS AND CONDITIONS OF, THIS OFFER DOCUMENT AND THE ACCEPTANCE DOCUMENTS.

K1 and Bidco wish to preserve the flexibility to enable them to elect to implement the acquisition of the MariaDB Shares by way of a scheme of arrangement of MariaDB under the Companies Act 2014. The consent of both the Irish Takeover Panel and MariaDB would be required to do so. K1 and Bidco may consider switching to a scheme of arrangement in the event that they consider that it would enable them to obtain 100% ownership of MariaDB in a shorter timeframe than the Offer.

From July 2023 through early October 2023, the Company engaged in an outreach to, and was contacted by, third parties regarding potential options to replace, refinance or restructure a loan outstanding in the amount of $15.9 million from the European Investment Bank which was scheduled to mature on 11 October 2023 (the “EIB Loan”). This included outreach by the Company to certain customers, financial institutions, investment banks, private equity firms (including Hale Capital Partners, L.P. (“Hale”)), and investors including current shareholders such as Open Ocean Opportunity Fund I Ky and its affiliates (collectively, “Open Ocean”), and Runa Capital Fund II, L.P., Runa Capital II (GP), Runa Capital Opportunity Fund I, L.P., Runa Capital Opportunity I (GP), and Runa Ventures I Limited (collectively, “Runa”).

From August 2023 through October 2023, the Company engaged in discussions with multiple third parties regarding potential equity financing options to refinance or restructure the EIB Loan and provide the Company with liquidity, including Runa and funds affiliated with Smartfin Management BV (namely Smartfin Capital II CommV and Smartfin Capital NV) (collectively, “Smartfin”), and provided such parties with due diligence information.

On 6 September 2023, following an introduction by an investment bank, a representative of K1 and the Company’s Chief Executive Officer, Paul O’Brien, held an initial telephonic conversation as part of K1’s general exploration of opportunities in the enterprise software space. This conversation included a discussion of the funding paths the Company was exploring. No commitment was asked of, or offered by, K1 with respect to the Company’s funding requirements. Mr. O’Brien indicated that the Company would be receptive to K1 maintaining contact with the Company from time to time and the representative of K1 suggested that the parties reconnect in October.

Throughout the period from August 2023 through 5 October 2023, the MariaDB board of directors (the “MariaDB Board”) held meetings via videoconference, including meetings at which Matheson LLP (Irish legal advisor to the Company) (“Matheson”) provided the directors with legal advice regarding their fiduciary duties under Irish law.

On 15 September 2023, Runa publicly announced, in accordance with Rule 2.4 of the Irish Takeover Rules, that on 14 September 2023 it had delivered a letter to the Company which contained a non-binding proposal to acquire 100% of the issued ordinary shares of the Company not owned by Runa at a price of $0.56 per share. Subsequently, on 10 October 2023, Runa announced, in accordance with Rule 2.8 of the Irish Takeover Rules, that it did not intend to make an offer for the Company.

On 10 October 2023, the Company entered into the RPV Note with RPV and used the proceeds to repay the EIB Loan in full. The maturity date of the RPV Note would occur on the earliest of (i) 10 January 2024, (ii) a change of control of the Company, (iii) any breach of any of the documentation relating to the EIB Loan or any demand for repayment of that loan, and (iv) the date on which the RPV Note otherwise became due and payable pursuant to its terms. The terms of the RPV Note restricted the Company, for the period until 10 January 2024, from pursuing or accepting any offer with respect to (x) any recapitalization, reorganization, merger, business combination, purchase, sale, loan, notes issuance, issuance of other indebtedness or other financing or similar transaction or (y) any acquisition by any person or group, which would result in any person or group becoming the beneficial owner of 2% or more of any class of equity interests or voting power or consolidated net income, revenue or assets, of the Company, in each case other than with RPV or Runa. The RPV Note also provided that the number of directors on the MariaDB Board be capped at four persons, and that two of the directors would be persons selected by RPV.

Also on 10 October 2023, promptly following the Company’s entry into the RPV Note, Hal Berenson, Christine Russell, Alex Suh and Theodore Wang resigned from the MariaDB Board and, pursuant to the RPV Note, at the direction of RPV, the Company appointed Yakov “Jack” Zubarev and Michael Fanfant to the MariaDB Board. Mr. Fanfant is a shareholder of Runa, which at the time, beneficially owned approximately 8.00% of the issued ordinary shares in the capital of the Company. As a result, as of 10 October 2023, the members of the MariaDB Board consisted of Mr. Jurgen Ingels, the Chairman of the MariaDB Board, Mr. Paul O’Brien, the Chief Executive Officer of the Company, Michael Fanfant and Yakov “Jack” Zubarev. Mr. Ingels is the

co-founder and managing partner of Smartfin. Various funds affiliated with Smartfin are existing shareholders of the Company. Mr. Ingels and Smartfin were, on 10 October 2023, and are shareholders of the Company. Mr. Ingels and Smartfin beneficially own approximately 8.59% of the issued ordinary shares in the capital of the Company as of 16 May 2024.

On 19 October 2023, a representative of K1 contacted Mr. O’Brien to request further details on the RPV Note. Mr. O’Brien referred K1 to the public press release regarding the RPV Note.

On 23 December 2023, Runa delivered to the Company a written proposal in the form of a draft term sheet providing for (x) the conversion of the outstanding principal and interest under the RPV Note into convertible preferred shares of the Company and (y) a $15 million cash investment by Runa and other third-party investors in exchange for the issuance of additional convertible preferred shares of the Company; provided, that RPV’s fees and expenses associated with the transaction would be credited against and reduce the cash purchase price to be paid by RPV for the convertible preferred shares (the “Potential RP Transaction”). In aggregate, it was expected that convertible preferred shares with an issue price of approximately $45 million would be issued in the Potential RP Transaction. It was expected that Open Ocean and Smartfin would participate in the cash investment pursuant to the Potential RP Transaction.

On 10 January 2024, no agreement on the Potential RP Transaction (or any other alternative to repay the RPV Note at maturity) had been reached and the parties to the RPV Note agreed to extend the stated maturity date of the RPV Note, together with the restrictive covenants thereunder, from 10 January 2024 to 31 January 2024 to provide the Company with additional time to continue negotiating a recapitalization arrangement with Runa. The Company paid RPV a nonrefundable funding fee of $75,000 relating to this amendment. During January and early February, Mr. Ingels and Gordon Caplan, a representative of Ilya Zubarev (the Chairman & Co-founder of Runa) would discuss from time to time the status of the Potential RP Transaction.

On 11 January 2024, in connection with a visit to the Bay Area by certain members of the K1 team that was unrelated to the Company, representatives of K1 met with Mr. O’Brien to discuss K1’s investment mandate and learn more about the history of the Company.

On or around 19 January 2024, in light of the relationship between Company directors Messrs. Fanfant and Zubarev and Runa and RPV and the conflict of interest associated with evaluating and negotiating the Potential RP Transaction, the MariaDB Board formed a special committee the (“Committee”) to evaluate the Potential RP Transaction and alternatives thereto and, ultimately, to make a recommendation to the MariaDB Board. The Committee, made up of Mr. Ingels and Mr. O’Brien, who were and are unrelated to Runa and RPV, engaged Baker Botts L.L.P. (“Baker Botts”) to serve as legal advisor and KPMG Corporate Finance Limited (“KPMG”) to provide a valuation of the Company’s business in the ordinary course.

From 19 January 2024 until 12 March 2024, the Committee met regularly to evaluate the Potential RP Transaction and potential alternative options for the Company and, at the direction of the Committee, Baker Botts engaged in negotiations with McDermott Will & Emery LLP (“McDermott”), counsel to Runa and RPV, regarding terms and conditions of a Potential RP Transaction. During this time period, the Company, Runa, RPV, Baker Botts, IBI Corporate Finance, Matheson, McDermott, and Runa’s external Irish legal counsel, or some or a combination of each, engaged in discussions regarding the terms and conditions of a Potential RP Transaction and began to exchange draft documentation related to the same.

On 26 January 2024, Hale delivered an unsolicited letter to the members of the Committee setting forth an indicative non-binding offer to acquire the entire issued, and to be issued, share capital of the Company in cash at a per-share price of $0.24 per share (the “First Hale Offer”). According to Hale, its offer implied a total enterprise value of the Company of $69.6 million and an equity value of approximately $16.0 million. Under the Irish Takeover Rules, following receipt of the First Hale Offer, the Company was prohibited, without the prior approval of its shareholders or the consent of the Irish Takeover Panel, from taking certain “frustrating actions” while the MariaDB Board had reason to believe that the making of an offer to acquire the Company is or may be imminent. The frustrating actions’ prohibitions are described in more detail in the Section titled “Frustrating Action” in Item 8. As a result, without the prior approval of the Company’s shareholders or the consent of the Irish Takeover Panel, the Company was prohibited from either: (A) implementing the Potential RP Transaction (or entering into an agreement to do so), or (B) extending the Company’s exclusivity obligations under the RPV Note, which were due to expire on 31 January 2024, unless in either case, (i) the indicative offer was withdrawn (or deemed, with Irish Takeover Panel consent, to have been withdrawn) by Hale or (ii) if the

indicative offer were to be publicly announced, Hale did not thereafter announce a firm intention to make an offer for the Company in accordance with Rule 2.7 of the Irish Takeover Rules by not later than 5:00 p.m., New York City time, on the 42^nd day following the date of such public announcement.

On 31 January 2024, the RPV Note matured and the Company did not pay the outstanding principal, interest, and other applicable fees or charges due and payable on the RPV Note. In addition, the Company and its subsidiaries, as guarantors under the RPV Note, failed to comply with certain other obligations under the RPV Note. This nonpayment and other noncompliance gave rise to events of default under the RPV Note.

On 31 January 2024 the Committee convened a meeting to evaluate the First Hale Offer and the Potential RP Transaction, including the commercial terms that had been agreed in connection with the Potential RP Transaction and legal and strategic risks to the Company in connection with the impending default under the RPV Note. The Committee also explored with counsel process and preparation for commencing proceedings under Chapter 11 of the U.S. bankruptcy code (a “Chapter 11 Process”) in the event no agreement with RPV on a forbearance or the Potential RP Transaction could be reached prior to or at maturity of the RPV Note. At the conclusion of such discussions, the Committee determined to make a recommendation to the MariaDB Board that: (i) the Company reject the First Hale Offer, (ii) the negotiated term sheet regarding the Potential RP Transaction be approved, subject to reaching agreement on the remaining open items, and (iii) the Company should seek a forbearance from RPV until the Potential RP Transaction could be finalized. Shortly thereafter, the MariaDB Board convened a meeting in which the Committee delivered the recommendations described above. The MariaDB Board, having considered the recommendations from the Committee, determined that the First Hale Offer should be rejected and that the Committee should continue to negotiate and finalize the terms of the Potential RP Transaction. Baker Botts then delivered a notice to Hale rejecting the First Hale Offer. Shortly thereafter, Hale delivered to Baker Botts an updated indicative non-binding offer (the “Second Hale Offer”) whereby Hale reiterated its interest in acquiring the entire issued and to be issued share capital of the Company at the same price of $0.24 per share.

On or around 3 February 2024, the Company re-engaged IBI Corporate Finance from a prior engagement in September 2023, on behalf of the Committee, to act as the Company’s Rule 3 financial advisor under the Irish Takeover Rules in evaluating the Potential RP Transaction and any inbound offers.

On 5 February 2024, McDermott, delivered a revised term sheet to Baker Botts that added Hale as a $10 million co-investor in the Potential RP Transaction in exchange for convertible preferred shares. Under the new terms, the term sheet provided for (x) the conversion of the outstanding principal and interest under the RPV Note into convertible preferred shares of the Company and (y) an aggregate anticipated cash investment of $23.5 million from Hale, RPV and other existing shareholders (which was expected to include Open Ocean and Smartfin) in exchange for additional convertible preferred shares with an aggregate issue price of approximately $50 million; provided, that RPV’s fees and expenses associated with the transaction would be credited against and reduce the cash purchase price to be paid by RPV for the convertible preferred shares. In addition, the updated term sheet provided that Hale would withdraw its indicative offer upon execution of the term sheet by the Company, RPV, and Hale.

Later that same day, the Company, RPV, and Hale entered into the term sheet and Hale withdrew the Second Hale Offer. As a result of the withdrawal by Hale of its Second Hale Offer, the Company was no longer prohibited by the Irish Takeover Rules from entering into the Potential RP Transaction or extending the Company’s exclusivity obligations under the RPV Note. Also on 5 February 2024, the Company and its subsidiaries, as guarantors under the RPV Note, entered a Forbearance Agreement with RPV (the “Forbearance Agreement”) which provided for, among other things, a forbearance from RPV exercising its rights and remedies under the RPV Note until the earlier of: (i) the execution of a definitive agreement to restructure the Company’s obligations under the RPV Note and any amendment or extension of the RPV Note, (ii) 11:59 pm Pacific Time on 21 February 2024, (iii) the occurrence or existence of certain events of default, (iv) initiation of any action by the Company or its subsidiaries, affiliates, or representatives to invalidate or limit the enforceability of certain provisions of the Forbearance Agreement, (v) a breach of the non-solicitation provisions of the Forbearance Agreement and (vi) the occurrence of certain insolvency events.

Under the terms of the Forbearance Agreement, the Company could not, directly or indirectly, initiate, solicit, take any action to facilitate or encourage any inquiries or making of any proposal or any indication of interest from any person or persons (other than RPV) that may constitute, or could be expected to lead to various

transactions, which would include an offer for the Company and the Company agreed that certain additional actions taken by or regarding the Company would constitute an immediate event of default under the Forbearance Agreement, the RPV Note and related security documents, without any notice or grace or cure period. These actions include, among other things, any public announcement by a third party regarding a proposed offer or other transaction with the Company that could result in a change of control. Upon the occurrence of an event of default, RPV had the right to declare the principal of and accrued interest on the RPV Note to be immediately due and payable.

On 15 February 2024, representatives of K1 delivered to Mr. Ingels, as chairman of the MariaDB Board, an unsolicited proposal letter whereby K1 indicated its interest in exploring an offer to acquire the entire issued, and to be issued, share capital of the Company at a price of $0.55 per share (the “K1 Proposal”). The proposed per share price represented, according to K1, a 189% premium to the closing stock price on 5 February 2024, the last full trading day prior to the announcement of the entry into the Forbearance Agreement, and a 129% premium to the average closing stock price of the preceding 30 calendar days.

The following day, K1 publicly announced, in accordance with Rule 2.4 of the Irish Takeover Rules, the K1 Proposal which constituted an immediate event of default under the Forbearance Agreement. As a result, the forbearance period under the Forbearance Agreement terminated on 16 February 2024, allowing RPV the right to declare all principal of and accrued interest on the RPV Note to be immediately due and payable. Interest on amounts due under the RPV Note began to accrue at the default rate of 2% above the otherwise-applicable non-default interest rate of 10%. In response to the announcement, a Notice of Default under the RPV Note was delivered to the Company and McDermott communicated that if the Company did not sign the definitive documentation for the Potential RP Transaction that same day, RPV would foreclose on the RPV Note and exercise control over the operating account (the “Operating Account”) of Company’s U.S. subsidiary, MariaDB USA, Inc. pursuant to that certain Deposit Account Control Agreement entered into in connection with the RPV Note, and transfer the funds in the Operating Account to an account controlled by RPV. However, under the Irish Takeover Rules, following receipt of the K1 Proposal, the Company was again prohibited, without the prior approval of its shareholders or the consent of the Irish Takeover Panel, from taking certain “frustrating actions” while the MariaDB Board had reason to believe that the making of an offer to acquire the Company is or may be imminent. As a result, without the prior approval of the Company’s shareholders or the consent of the Irish Takeover Panel, the Company was prohibited from implementing the Potential RP Transaction (or entering into an agreement to do so), unless the K1 Proposal was withdrawn or K1 did not thereafter announce a firm intention to make an offer for the Company in accordance with Rule 2.7 of the Irish Takeover Rules prior to the expiry of the K1 Offer Period described below.

As a result of the public announcement of the K1 Proposal, K1 was required, under the Irish Takeover Rules, no later than 5:00 pm, New York City time, on 29 March 2024, being the 42^nd day following the K1 announcement (the “K1 Offer Period”), to either (i) announce a firm intention to make an offer for the Company in accordance with Rule 2.7 of the Irish Takeover Rules; or (ii) announce that it did not intend to make an offer for the Company. The K1 Offer Period would be extended only with the consent of the Irish Takeover Panel at the request of the Company. If K1 did not make an offer for the Company in accordance with Rule 2.7 of the Irish Takeover Rules prior to the expiration of the K1 Offer Period, it would be restricted from making an additional offer for the Company for a period of six months from that time.

On 17 February 2024, affiliates of K1 entered into a non-disclosure agreement with the Company. On the same day, pursuant to the Deposit Account Control Agreement, RPV delivered an Activation Notice to Bank of America exercising control over the Operating Account and instructing Bank of America to deliver the funds in the Operating Account to an account controlled by RPV. The Operating Account was subsequently unfrozen on 26 February 2024, pursuant to instructions from RPV to Bank of America.

During the period following receipt of the K1 Proposal through 12 March 2024, some or a combination of representatives of the Company, Baker Botts, Matheson, and IBI Corporate Finance held various conversations with, at different times, some or a combination of representatives of K1, Kirkland & Ellis LLP (“K&E”), external legal advisor to K1, A&L Goodbody LLP (“ALG”), external Irish counsel to K1, and Lazard in connection with K1’s possible offer. These conversations included diligence calls with representatives of management and the broader MariaDB team on certain matters, including financial and tax diligence, legal diligence, technology diligence, organizational structure and design, go-to-market strategy, sales pipeline, renewals forecasts and renewal processes. No transaction agreement (or similar) was ever negotiated by K1 or

any of the K1 Group with the Company or any representative of the Company. In addition, during the same period, multiple discussions were had among one or more of representatives of K1, Baker Botts, and McDermott regarding the Company’s financial situation, the terms of a potential bridge loan as well as a possible Chapter 11 Process and associated debtor-in-possession financing.

During the month of February, 2024, various discussions among some or a combination of representatives from K1, K&E, ALG, and Lazard, on the one hand, and RPV and McDermott, on the other hand, took place regarding whether there was any potential arrangement between K1 and RPV (or certain of its affiliates) to be entered into in connection with a financing solution for the Company. Ultimately, K1 and RPV did not reach agreement on any such arrangement and such discussions ceased at the end of February.

During late February through late March, representatives from K1 held various conversations with certain MariaDB Shareholders to solicit their opinions on the actions and inactions of the MariaDB Board with respect to the K1 Proposal. Certain of those MariaDB Shareholders made clear that while they may be willing to tender into a binding offer from K1, if one were to be made, they did not anticipate taking any other actions in their capacities as MariaDB Shareholders. As part of conversations with MariaDB Shareholders during this period (specifically on or around 19 February 2024), certain MariaDB Shareholders expressed that K1’s non-binding proposal would be more attractive to them if they were offered the opportunity to participate in a rollover type structure. Representatives of K1 did not engage, at this time, on the suggestion of a rollover, but ultimately included such an option (as the Unlisted Unit Alternative) as part of its proposal.

During this same period, each of the Committee and the MariaDB Board held various meetings to discuss the Company’s financial situation and the potential inability of the Company to meet its financial obligations, the possibility of commencing a Chapter 11 Process and the potential outcomes for the Company, and the possibility of consummating a transaction pursuant to the K1 Proposal.

On 20 February 2024, Runa filed a Schedule 13-D/A announcing that it had formed a shareholder “group” with Michael (Monty) Widenius, the Company’s founder and former Chief Technology Officer and who, according to the Schedule 13-D/A beneficially owned approximately 0.6% of the Company’s outstanding ordinary shares. The Schedule 13-D/A disclosed that Mr. Widenius had entered into a letter agreement with Runa, whereby he agreed, among other things, to work exclusively with Runa, Smartfin, and Open Ocean with respect to any transaction with the Company. In exchange for such exclusivity, Runa agreed that Mr. Widenius would be provided the opportunity to invest in any transaction between the Company and Runa that involves any form of financing, acquisition or change of control of the Company, including any acquisition of all or a material portion (5% or more) of the assets or equity of the Company or any of subsidiaries.

On 21 February 2024, Yogesh Gupta, CEO of Progress Software Corporation (“Progress”), contacted Mr. O’Brien to discuss a potential indicative offer from Progress to acquire the Company and, on 1 March 2024, the Company and Progress entered into a non-disclosure agreement.

On 28 February 2024, the Committee held a meeting to discuss the K1 Proposal, including the likely inability of K1 to successfully complete an acquisition of the Company due to lack of support from RV, Smartfin, Open Ocean, and Mr. Widenius, and the possibility of the Company commencing a Chapter 11 Process.

On 4 March 2024, the Committee held a meeting where it discussed that neither the Potential RP Transaction nor the K1 Proposal were actionable at the present time due to, among other things, the restrictions under the Irish Takeover Rules and the perceived inability of K1 to successfully complete an acquisition. The Committee recommended that the MariaDB Board commence the making of preparations, solely as a contingency planning matter, for commencing a Chapter 11 Process (the “Contingency Planning Recommendation”). On 5 March 2024, the MariaDB Board held a meeting to discuss the Contingency Planning Recommendation and directed the Committee to prepare a comparative analysis of the Potential RP Transaction, the K1 Proposal, and a Chapter 11 Process.

On 7 March 2024, KPMG presented its valuation analysis of the Company (the “Valuation”) to the Committee and Mr. Godfrey presented to the Committee IBI Corporate Finance’s analysis comparing the implications on the Company’s shareholders of the K1 Proposal, the Potential RP Transaction, and a Chapter 11 Process (the “IBI Corporate Finance Analysis”). The Valuation indicated that the Company likely had equity value notwithstanding amounts payable under the RPV Note. The IBI Corporate Finance Analysis stated that the Potential RP Transaction was inferior to both the K1 Proposal and potential U.S. Chapter 11 Process.

On 12 March 2024, the MariaDB Board held a meeting and dissolved the Committee. The MariaDB Board also elected to not renew the terms of Mr. O’Brien’s Employment Agreement, dated as of 26 May 2023, and Mr. O’Brien’s employment as Chief Executive Officer of the Company was expected to terminate as of 26 May 2024. On 13 March 2024, upon receipt by Mr. O’Brien of a request in writing signed by each of Messrs. Ingels, Fanfant, and Zubarev, the other directors on the MariaDB Board, for him to resign as a director of the Company, Mr. O’Brien’s office as a director of the Company was vacated with immediate effect.

At its 12 March 2024 meeting, the MariaDB Board further resolved to appoint Chris Creger, a Senior Managing Director of FTI Consulting, Inc. (“FTI”) to serve as its Chief Restructuring Officer to primarily assist with an evaluation of the Company’s cash flows, advise on liquidity opportunities and assess operating business and profitability plans. Mr. Creger was formally engaged pursuant to an engagement letter, effective 18 March 2024, between the Company and FTI.

On 21 March 2024, Runa, Michael (Monty) Widenius, Smartfin, Bart Luyten, Jurgen Ingels, Open Ocean, Patrik Backman, and Ralf Wahlsten filed a Schedule 13-D/A announcing that they had formed a group to collectively express their opposition to the K1 Proposal and that on 19 March 2024, Runa, Open Ocean, and Smartfin delivered a letter to the Company in which they stated their opposition to the K1 Proposal because they did not believe the K1 Proposal was in the best interests of the Company or its shareholders.

On 24 March 2024, at the request of representatives of K1, representatives of Lazard held a call with representatives of RPV where such representatives indicated that RPV would be amenable to selling the RPV Note at a premium to K1. K1’s outreach resulted from a failure of the conversations referred to above during the month of February on a potential financing solution for the Company with RPV and, consequently, the RPV Note, the terms of which were likely incompatible with a successful offer from K1.

On 25 March 2024, K1 submitted a proposal to RPV offering to purchase the RPV Note for cash consideration of $50 million, together with $2 million for RPV’s accrued expenses to such point. Following feedback from representatives of RPV that same day, on 26 March 2024, K1 made a revised proposal, offering to purchase the RPV Note for aggregate total consideration (including accrued expenses of RPV) of $65 million. This proposal was delivered to RPV as a non-binding term sheet containing additional provisions, including a release, resignation of the directors appointed by RPV and certain other matters.

On 26 March 2024, Progress publicly announced, pursuant to Rule 2.4 of the Irish Takeover Rules, that it was considering a possible offer for all the issued, and to be issued, share capital of the Company at a value of $0.60 per share (the “Progress Proposal”).

On 28 March 2024, RPV returned to K1 a markup of the term sheet, increasing the proposed consideration for the RPV Note to $67.1 million, among other changes to the term sheet.

On 29 March 2024, at the formal request of the MariaDB Board, the Irish Takeover Panel consented, pursuant to Rule 2.6(c) of the Irish Takeover Rules, to an extension until 5.00 p.m. (New York time) on 12 April 2024 of the K1 Offer Period. A further extension, at the request of the MariaDB Board, was granted by the Irish Takeover Panel on 12 April 2024, which extended the K1 Offer Period until 5:00 p.m., New York City time, on 22 April 2024, and a further extension to 5:00 p.m., New York City time, on 24 April 2024, was granted on 22 April 2024. K1 had requested that the MariaDB Board ask the Irish Takeover Panel for each of these extensions, in order to provide K1 additional time to continue to negotiate the terms of the K1 Proposal.

On 1 April 2024, Mr. Ingels held a call with Mr. Gupta to discuss the background of Progress and the Progress Proposal.

On 1 April 2024, Runa, Michael (Monty) Widenius, Smartfin, Bart Luyten, Jurgen Ingels, Open Ocean, Patrik Backman and Ralf Wahlsten filed a Schedule 13-D/A announcing that on 27 March 2024, they delivered a letter to the Company in which they stated their opposition to the K1 Proposal and the Progress Proposal.

On 4 April 2024, representatives of Smartfin, Open Ocean, and K1 met to discuss the history and background of the Company.

On 5 April 2024, the Irish Takeover Panel granted a derogation from Rules 20.1 and 20.2 of the Irish Takeover Rules to permit K1 to seek irrevocable undertakings from certain Company shareholders prior to the publication of its announcement of a firm intention to make an offer for the Company. On 9 April 2024, at the direction of K1, Lazard began the process of contacting those specified shareholders, in accordance with the terms of the

derogation granted by the Irish Takeover Panel which required meetings with those shareholders to be chaperoned by Lazard. During that outreach, certain shareholders expressed a desire to participate in a rollover opportunity, and subsequently the negotiations included discussions of the Unlisted Unit Alternative and whether each Company shareholder wished to elect for that alternative. The negotiation of the irrevocable undertakings between K1 and its representatives and the specific shareholders and their representatives continued until immediately prior to the release by K1 of the Rule 2.7 announcement on 24 April 2024, of the recommended cash offer to be made by Bidco, an affiliate of K1, for the entire issued and to be issued share capital of the Company. Company shareholders representing approximately 51.53% of the issued ordinary shares in the capital of the Company as of 24 April 2024 executed irrevocable undertakings on 24 April 2024, each in substantially the same form, with only minor deviations. A description of the form of irrevocable undertaking, such minor deviations, and which shareholders executed irrevocable undertakings, is set forth in Section titled “Irrevocables” in Item 6 of the Offer Document.

On 9 April 2024 and 11 April 2024, K&E provided McDermott with initial drafts of the documentation required in connection with the purchase of the RPV Note, including a loan purchase agreement. Between 9 April 2024 and 24 April 2024, K&E and McDermott exchange multiple drafts of the loan purchase related documents and held multiple calls to negotiate the terms of such documents. Provisions negotiated included: (i) the scope of certain restrictive covenants, including the standstill, (ii) the terms of the mutual release, (iii) the representations and warranties, (iv) director and officer “tail coverage” and (v) claims that the former noteholder could retain. As part of the negotiations, the final purchase price was agreed upon as approximately $62.4 million plus approximately $4.5 million comprised of accrued interest under the RPV Note and the transaction expenses of RPV. During this time, as part of these negotiations, representatives of K1 and its advisors held multiple conversations with representatives of RPV and its advisors to negotiate the terms of the documentation. The final documentation relating to the purchase of the RPV Note by Topco was executed on 24 April 2024. Pursuant to the terms of the RPV Note, Topco exercised its right to appoint two directors to the MariaDB Board. Consequently, Michael Fanfant and Yakov “Jack” Zubarev resigned as directors of the Company with effect from completion of the acquisition of the RPV Note. George Mansour and Jordan Wappler were appointed to the MariaDB Board as the nominees of the new holder of the RPV Note immediately following the release by K1 of the Rule 2.7 announcement on 24 April 2024.

On 19 April 2024, Progress released a subsequent announcement in accordance with Rule 2.4 of the Irish Takeover Rules re-confirming the Progress Proposal and also stating that, in connection with the closing of the transactions contemplated by its offer, Progress would purchase the RPV Note for $40 million, less any amounts attributable to ownership of the Company’s shares.

On 24 April 2024, Bidco, an affiliate of K1, as manager of K5 Private Investors, L.P., made an announcement in accordance with Rule 2.7 of the Irish Takeover Rules of its firm intention to make the Offer (comprising (i) the recommended Cash Offer and (ii) the Unlisted Unit Alternative), the terms of which are described in more detail in the Section titled “Offer” in Item 2. The announcement included that IBI Corporate Finance had concluded that the terms of the Cash Offer were fair and reasonable and it would recommend that the MariaDB Shareholders should accept the Cash Offer.

On 26 April 2024, Runa, Michael (Monty) Widenius, Smartfin, Bart Luyten, Jurgen Ingels, Open Ocean, Patrik Backman, and Ralf Wahlsten filed a Schedule 13-D/A announcing that on 24 April 2024, (i) Runa and Topco entered into the loan purchase agreement and (ii) Bidco announced the terms of the Offer. In connection with the Offer, Runa, Michael (Monty) Widenius, Smartfin, Jurgen Ingels, Open Ocean, and Patrik Backman entered into Deeds of Irrevocable Undertakings in which they each agreed to accept (i) the Offer or alternatively (if Bidco or certain affiliates of Bidco elect to switch to a scheme of arrangement with respect to the Company under the Irish Companies Act 2014) the scheme of arrangement under the Companies Act 2014 and (ii) other than Runa, elect for the Unlisted Unit Alternative. In connection therewith, Runa, Smartfin, Open Ocean, Bart Luyten, Jurgen Ingels, Patrik Backman, Ralf Wahlsten, and Michael (Monty) Widenius entered into a Letter Agreement in which they agreed to dissolve their group.

On 1 May 2024, the Company engaged Baker Botts to represent the Company in connection with the K1 Proposal and thereafter Baker Botts, Matheson, ALG, and K&E engaged in discussions regarding and exchanged draft documentation to implement the Offer.

On 2 May 2024, Progress announced pursuant to Rule 2.8 of the Irish Takeover Rules that it had no intention to make an offer to acquire the Company.

Following 24 April 2024 until the date of this document, K1 and its representatives contacted additional MariaDB Shareholders and obtained irrevocables with respect to an additional 18.10% of the MariaDB Shares.

On 24 May 2024, K1 commenced the Offer and filed its Schedule TO.

K1 and Bidco retained Lazard Frères to act as sole financial advisor to K1 and Bidco in connection with the Offer and to provide an estimate of the value of the Topco Rollover Units in accordance with Rule 24.11 of the Irish Takeover Rules. Lazard Frères delivered its written valuation to Bidco on 24 May 2024 (the “Estimate of Value Letter”), to the effect that, as of the Latest Practicable Date, and based upon and subject to the assumptions made, procedures followed, matters considered and other qualifications and limitations set forth therein, the fair market value of the Topco Rollover Units was in the range of $0.40 to $0.65 per Topco Rollover Unit.

The full text of Lazard Frères’ Estimate of Value Letter, dated 24 May 2024, which sets forth the assumptions made, procedures followed, matters considered and qualifications and limitations on the review undertaken by Lazard Frères in connection with its Estimate of Value Letter, is attached to this Offer Document as Appendix 3 and is incorporated by reference herein in its entirety. The summary of Lazard Frères’ Estimate of Value Letter is qualified in its entirety by reference to the full text of the Estimate of Value Letter, and MariaDB Shareholders are encouraged to read the Estimate of Value Letter carefully and in its entirety.

Lazard Frères’ engagement and its Estimate of Value Letter were for the benefit of K1 and Bidco and its Estimate of Value Letter was rendered to the Bidco board of directors solely for the purposes of Rule 24.11 of the Irish Takeover Rules, and is not a valuation that has been prepared as a result of the requirements of, or in accordance with the terms of any applicable law or regulations in any jurisdiction other than Ireland. Lazard Frères’ Estimate of Value Letter is not intended to and does not constitute a recommendation to any MariaDB Shareholder as to whether they should accept the offer or make an election for the Unlisted Unit Alternative, or as to how they should vote or act with respect to the Offer or any matter relating thereto.

The Estimate of Value Letter was rendered as of the Latest Practicable Date on the basis of economic, monetary, market, general business, financial and other conditions prevailing on that date and the condition and prospects, financial and otherwise, of Topco as they were reflected in the information provided to Lazard Frères. Any changes therein may affect the Estimate of Value Letter and Lazard Frères disclaims any undertaking or obligation to advise any person of any such change that may come to its attention after such date or to change or withdraw the Estimate of Value Letter. Lazard Frères further notes that the current volatility and disruption in the credit and financial markets as of the Latest Practicable Date may or may not have an effect on MariaDB, K1, Bidco or Topco and Lazard Frères expressed no opinion as to the effects of such volatility or such disruption on MariaDB, K1, Bidco or Topco. In its analysis in connection with the preparation of the Estimate of Value Letter, Lazard Frères made numerous assumptions with respect to industry performance, general business and economic conditions, and other matters, many of which are beyond the control of Lazard Frères, MariaDB, K1, Bidco and Topco. The Estimate of Value Letter does not address the relative merits of the Offer as compared to other transactions or business strategies that might be available to K1, Bidco or Topco, the merits of the underlying decision by K1, Bidco and Topco to engage in the Offer, or the election which Eligible MariaDB Shareholders may make in respect of the Unlisted Unit Alternative. Lazard Frères expressed no opinion with respect to the future trading prices of securities of MariaDB or any of its affiliates or the future value at which Topco Rollover Units may be sold. In addition, Lazard Frères expressed no view or opinion as to the fairness of the amount or nature of, or any other aspects relating to, the compensation to any officers, directors or employees of any parties involved in the Offer, or class of such persons, relative to the consideration payable to MariaDB Shareholders or otherwise.

In connection with the Estimate of Value Letter, Lazard Frères:

Lazard Frères assumed and relied upon the accuracy and completeness of the foregoing information, without independent verification of such information. The Estimate of Value Letter is conditional upon such accuracy and completeness. Lazard Frères did not conduct any independent valuation or appraisal of any of the assets or liabilities (contingent or otherwise) of MariaDB, Bidco or Topco or concerning the solvency of MariaDB, Bidco or Topco, and Lazard Frres was not furnished with any such valuation or appraisal. Lazard Frères did not have access to the management of MariaDB in connection with the preparation of the Estimate of Value Letter and did not receive financial forecasts prepared by management of MariaDB other than limited financial forecasts prepared by MariaDB in December 2023 which covered only their expectations at that time with respect to 2024. Accordingly, for purposes of the Estimate of Value Letter, at K1’s and Bidco’s direction, Lazard Frères utilized only the Forecasts (and not any other forecast scenario provided by K1). With respect to the Forecasts utilized in Lazard Frères’ analyses, Lazard Frères assumed, with the consent of K1 and Bidco, that they were reasonably prepared by K1 on bases reflecting K1’s best currently available estimates and judgments as to the future financial performance of Topco. In addition, Lazard Frères assumed, with the consent of K1 and Bidco, that the Forecasts would be realized in the amounts and at the times contemplated thereby. Lazard Frères assumed no responsibility for and expressed no view as to the Forecasts or the assumptions on which they were based. Lazard Frères has assumed the accuracy and fair presentation of, and relied upon, MariaDB’s audited financial statements and the reports of the auditors thereon and MariaDB’s unaudited interim financial statements.

Under Rule 13e-3 of the Exchange Act, a summary of the bases for and methods of arriving at the conclusions of the Estimate of Value Letter must be filed with the SEC (the “Lazard Report”). The Irish Takeover Panel considers that certain projections contained in the Lazard Report and used by Lazard Frères in connection with its preparation of the Estimate of Value Letter to be profit forecasts within the meaning of Rule 28 of the Irish Takeover Rules. However, following consideration of the exceptional circumstances of the matter, the Irish Takeover Panel granted a waiver of the requirement to procure (i) the reports from reporting accountants and financial advisors required by Rule 28.1(a) of the Irish Takeover Rules, and (ii) for the directors’ confirmations required by Rule 28.2(a) of the Irish Takeover Rules in connection with those projections, because the relevant projections are disclosed solely to comply with SEC requirements.

In rendering its Estimate of Value Letter, Lazard Frères assumed, with the consent of K1 and Bidco, that as of the Latest Practicable Date the Offer had become Effective, that Bidco had full control of MariaDB, that the Topco Rollover Units had been validly issued and the Offer would be implemented on the terms described in the Offer Document, without any modification of any material terms or conditions. Lazard Frères also assumed, with the consent of K1 and Bidco, that obtaining the necessary governmental, regulatory or third party approvals and consents for the Offer would not have an adverse effect on MariaDB, Bidco, Topco or the Offer and that, following the Offer becoming Effective, Topco would both (i) cancel the RPV Note and (ii) provide additional equity of at least $23 million to MariaDB. Lazard Frères did not express any opinion as to any tax or other

consequences that might result from the Offer or the holding of Topco Rollover Units, nor did Lazard Frères’ Estimate of Value Letter address any legal, tax, regulatory or accounting matters, as to which Lazard Frères understood that K1 and Bidco obtained such advice as they deemed necessary from qualified professionals. Lazard Frères expressed no view or opinion as to any terms or other aspects of the Offer, including, without limitation, the form or structure of the Offer or any agreements or arrangements entered into in connection with, or contemplated by, the Offer.

In analyzing the range of value of the Topco Rollover Units for purposes of the Estimate of Value Letter, no account has been taken of any potential transaction costs that a holder of Topco Rollover Units may incur, including any associated dealing costs, or any potential costs that may be associated with a sale of Topco to a third party or a liquidation of Topco and which might be expected to reduce any return to a holder of a Topco Rollover Unit upon the occurrence of such an event. In addition, no account has been taken of any minority shareholder issues arising from the existence of a controlling member in Topco, or the fact that K5, a controlling shareholder of Topco has power to appoint all of the members of the board of Topco, who have the exclusive authority and power to manage the business and affairs of Topco, and we have not made any adjustment for such factors. Lazard Frères noted that in analyzing the value of the Topco Rollover Units, MariaDB Shareholders may wish to apply a discount to take into account the illiquidity or non-transferability of the Topco Rollover Units, the governance arrangements in relation to Topco, and the other factors described in the Estimate of Value Letter that may impact value, based on, among other things, the type of holder and their individual circumstances. Lazard Frères makes no estimate of, and expresses no opinion as to, the materiality or amount of any such discount.

The following is a summary of the material financial analyses provided by Lazard Frères to the board of directors of Bidco in connection with the Estimate of Value Letter. The summary of Lazard Frères’ analyses provided below is not a complete description of the analyses underlying the Estimate of Value Letter. The preparation of the Estimate of Value Letter is a complex process and is not necessarily amenable to partial analysis or summary description. Lazard Frères believes that its analyses must be considered as a whole and that selecting portions of the analyses or the factors considered by Lazard Frères, without considering all factors and analyses together, could create an incomplete view of the process underlying the Estimate of Value Letter. Accordingly, the Estimate of Value Letter should be read in its entirety.

The Estimate of Value Letter is based upon techniques and assumptions that Lazard Frères considered appropriate in the circumstances for the purposes of arriving at an estimate as to the fair market value of the Topco Rollover Units.

In determining the fair market value of the Topco Rollover Units, Lazard Frères primarily relied on a valuation analysis based on comparable companies public trading analysis and discounted cash flow analysis. Lazard Frères did not make any adjustment for the illiquidity or non-transferability of the Topco Rollover Units, the governance arrangements in relation to Topco, or the other factors described in the Estimate of Value Letter that may impact value, either in relation to the discount rate used in the discounted cash flow analysis, or in relation to the Estimate of Value Letter itself. Any assessment of the value of the Topco Rollover Units to an individual shareholder should take into account an individual shareholder's assessment of an appropriate discount to reflect the illiquidity of the Topco Rollover Units, the other governance arrangements in relation to Topco and such other factors.

The summary of the analyses and reviews provided below includes information presented in tabular format. To fully understand Lazard Frères’ analyses and reviews, the tables must be read together with the full text of each summary. The tables alone do not constitute a complete description of Lazard Frères’ analyses and reviews. Considering the data in the tables below without considering the full description of the analyses and reviews, including the methodologies and assumptions underlying the analyses and reviews, could create a misleading or incomplete view of Lazard Frères’ analyses and reviews.

Comparable Companies Public Trading Analysis

Lazard Frères reviewed and analyzed certain financial information, valuation multiples and market trading data related to selected comparable publicly traded software companies with financial performance profiles that Lazard Frères believed, based on its experience with companies in the software industry and professional

judgment, to be generally relevant in analyzing MariaDB’s operations for purposes of this analysis. Lazard Frères compared such information of the selected comparable companies to the corresponding information for MariaDB to perform a valuation analysis.

The selected group of companies Lazard Frères reviewed (the “select comparable companies”) were:

Lazard Frères selected the companies reviewed in this analysis because, among other things, the select comparable companies have financial profiles similar to MariaDB on a current basis. However, no selected entity is identical to MariaDB and certain of these companies may have characteristics that are materially different from those of MariaDB. Accordingly, Lazard Frères believes that purely quantitative analyses are not, in isolation, determinative and that qualitative judgments concerning differences between the businesses, financial and operating characteristics and prospects of MariaDB and the select comparable companies are also relevant.

For each of the select comparable companies, Lazard Frères calculated and compared various financial multiples and ratios, including, among other things, (a) the ratio of each company’s enterprise value (“EV”) to its estimated 2024 revenues and 2025 revenues, respectively, and (b) the ratio of each company’s EV to its estimated 2024 gross profit and 2025 gross profit, respectively.

Lazard Frères calculated each select comparable company’s EV as its market capitalization (based on each company’s closing share price as of the Latest Practicable Date and most recently publicly reported share count information (taking into account dilution from outstanding options and unvested stock units)), plus debt, debt-like items and noncontrolling interests, and less cash and cash equivalents and equity method investments. The EV, revenue and gross profit estimates for each of the select comparable companies used by Lazard Frères in its analysis were based on brokers’ consensus estimates and other publicly available information, and calendarized to a September 30 fiscal year end, consistent with MariaDB’s fiscal year. Lazard Frères then calculated the lower and upper quartile for the select comparable companies. The following table summarizes the results of this review.

Based on its professional judgment after taking into account, among other things, the analysis of the relevant metrics for each of the select comparable companies with respect to the fiscal year ending 30 September 2024, Lazard Frères selected an EV to revenue multiple range of 1.9x to 2.9x and applied it to Topco’s estimated 2024 revenues as set forth in the Forecasts.

Based on its professional judgment after taking into account, among other things, the analysis of the relevant metrics for each of the select comparable companies with respect to the fiscal year ending 30 September 2025, Lazard Frères selected an EV to revenue multiple range of 1.7x to 2.7x and applied it to Topco’s estimated 2025 revenues as set forth in the Forecasts.

Based on its professional judgment after taking into account, among other things, the analysis of the relevant metrics for each of the select comparable companies with respect to the fiscal year ending 30 September 2024, Lazard Frères selected an EV to gross profit multiple range of 2.2x to 3.6x and applied it to Topco’s estimated 2024 gross profit as set forth in the Forecasts.

Based on its professional judgment after taking into account, among other things, the analysis of the relevant metrics for each of the select comparable companies with respect to the fiscal year ending 30 September 2025, Lazard Frères selected an EV to gross profit multiple range of 2.0x to 3.3x and applied it to Topco’s estimated 2025 gross profit as set forth in the Forecasts.

Lazard Frères then calculated an implied equity value range per Topco Rollover Unit using the Forecasts and (1) an estimated net cash position of $1.1 million as of the Latest Practicable Date, as provided by K1’s management and (2) 225,134,526 Class A Topco Units and 39,729,622 Topco Rollover Units, as provided by K1’s management.

The analysis resulted in the following ranges of implied values per Topco Rollover Unit (rounded to the nearest $0.01 per share).

Lazard Frères also performed a discounted cash flow analysis of Topco by calculating, based on the Forecasts, the estimated present value (as of the Latest Practicable Date) of the unlevered, after-tax free cash flows that Topco was forecasted by management of K1 to generate for each of fiscal years 2024 through 2029. Lazard Frères also calculated a terminal value for Topco by applying (i) a perpetuity growth rate of 2.0% to the unlevered, after-tax free cash flow of Topco for the terminal year of Topco as reflected in the Forecasts, which perpetuity growth rate was selected based on Lazard Frères’ professional judgment and experience, taking into account, among other things, the Forecasts and trends in the overall economy generally and in the industry in which MariaDB operates, and (ii) a 10% discount, as directed by K1 and Bidco for purposes of the discounted cash flow analysis, to reflect the illustrative dilutive effect of an illustrative management incentive plan.

The estimated future cash flows and terminal value were discounted to the present value date using a discount rate of 16.1%. Such discount rate was chosen by Lazard Frères based upon its analysis of Topco’s weighted average cost of capital, determined using the capital asset pricing model and based on considerations that Lazard Frères deemed relevant in its professional judgment and experience, using market data available as of the Latest Practicable Date and taking into account certain financial metrics, including betas for an operationally comparable group of companies.

The analysis indicated an implied enterprise value range for Topco, from which Lazard Frères then calculated a value range per Topco Rollover Unit using (1) an estimated net cash position of $1.1 million as of the Latest Practicable Date, 2024, as provided by K1’s management, and (2) of 225,134,526 Class A Topco Units and 39,729,622 Topco Rollover Units, as provided by K1’s management.

The analysis based on the Forecasts resulted in a range of implied values per Topco Rollover Unit (rounded to the nearest $0.01 per share) of $0.46 – $0.60.

Based upon and subject to the foregoing, and the assumptions and limitations set forth in the Estimate of Value Letter, in addition to other factors considered relevant, Lazard Frères was of the opinion that, as of the Latest Practicable Date, the fair market value of the Topco Rollover Units was in the range of $0.40 to $0.65 per Topco Rollover Unit.

The K1 and Bidco boards of directors selected Lazard as their financial advisor in connection with the Offer based on Lazard’s reputation, qualifications and experience in investment banking and mergers and acquisitions generally and in the software industry specifically, as well as its knowledge of K1’s and Bidco’s business and affairs and the industry in which they operate. Lazard is an internationally recognized investment banking firm that has substantial experience in transactions similar to the Offer.

Lazard, as part of its investment banking business, is continually engaged in the valuation of businesses and their securities in connection with mergers and acquisitions, negotiated underwritings, secondary distributions of listed and unlisted securities, private placements, leveraged buyouts, and valuations for estate, corporate and

other purposes. Lazard has provided and in the future may provide investment banking and other services to or with respect to K1, Bidco, Topco, or their respective affiliates or portfolio companies, as applicable, for which Lazard may receive compensation; in particular, in the last two years, an affiliate of Lazard was retained by a portfolio company of K1 with respect to a matter that is not active at this time. In addition, in the ordinary course, Lazard and its affiliates and employees may trade securities of K1, Bidco, Topco, MariaDB and certain of their respective affiliates and portfolio companies, as applicable, for their own accounts and for the accounts of their customers and, accordingly, may at any time hold a long or short position in such securities, and may also trade and hold securities on behalf of K1, Bidco, Topco, MariaDB and certain of their respective affiliates. The issuance of the Estimate of Value Letter was approved by the Opinion Committee of Lazard Frères.

In connection with Lazard Frères’ services as financial advisor and evaluator to K1 and Bidco, K1 and Bidco have agreed to pay Lazard Frères an aggregate fee for such services equal to $1,800,000, $300,000 of which became payable upon delivery of the Estimate of Value Letter, no part of which was contingent upon the conclusions reached in the Estimate of Value Letter, $1,250,000 of which is payable contingent upon the closing of the Offer, with an additional fee of $250,000 payable at the closing of the Offer at the discretion of K1 and Bidco, based on their view of Lazard’s performance and the result of the Offer. In addition, K1 and Bidco agreed to reimburse Lazard Frères for certain expenses incurred in connection with Lazard Frères’ engagement, and K1, Bidco and K5 agreed to indemnify Lazard Frères and certain related persons against certain liabilities that may arise from or related to Lazard Frères’ engagement.

The purpose of the Offer is for Bidco and the K1 Group to acquire control of, and the entire equity interest in (less the portion of Topco issued to former MariaDB Shareholders as part of the Unlisted Unit Alternative, if any), MariaDB. The Offer, as a first step in Bidco’s acquisition of MariaDB, is intended to facilitate the acquisition of all of the MariaDB Shares. The purpose of the Buy Out (as defined below) is to acquire all of the MariaDB Shares not purchased pursuant to the Offer and to cause MariaDB to become a wholly owned subsidiary of Bidco.

If the Offer becomes or is declared unconditional in all respects and sufficient acceptances have been received at the Expiration Time, following closing of the Offer, Bidco intends to effect the Buy Out.

After the Offer has closed and as soon as it is appropriate and possible to do so, Bidco intends to cause MariaDB to apply for cancellation of the listing of the MariaDB Shares on the NYSE, and to propose a resolution to re-register MariaDB as a private company under the relevant provisions of the Companies Act 2014.

We believe that, as a private company, MariaDB will be able to improve its ability to execute initiatives that over time will create additional enterprise value for MariaDB, which are in some cases more difficult for businesses to achieve as a public company due to the investment community’s focus on short-term, often quarterly, financial results. Further, absent the reporting and associated costs and burdens placed on public companies, we believe that MariaDB’s management and employees will be able to execute more effectively on future strategic plans. In addition, we will benefit from the savings associated with MariaDB no longer being required to file reports under or otherwise having to comply with provisions of the Exchange Act. Detriments of the Offer to the K1 Group include the lack of liquidity for MariaDB Shares following the Offer and the risk that MariaDB will decrease in value following the Offer. See paragraph 11 of the Letter from the President of Bidco for further information.

K1 intends to conduct a comprehensive review of MariaDB’s business, operations, capitalization and management following completion of the Transactions. Accordingly, we are not in a position to discuss specific plans and timelines at this time. However, other than as described in this Offer Document (including the immediately following paragraph), we have no present plans or proposals (other than the Buy Out, the delisting and the deregistration, each as described herein) that would relate to or result in (i) any extraordinary corporate transaction involving MariaDB or any of its subsidiaries (such as a merger, reorganization, liquidation, relocation of any operations or sale or other transfer of a material amount of assets), (ii) any change in the board of MariaDB or management, (iii) any material change in MariaDB’s capitalization or dividend policy, (iv) any other material change in MariaDB’s corporate structure or business or (v) any class of equity securities of MariaDB becoming eligible for termination of registration pursuant to Section 12(g) of the Exchange Act.

If the Offer is consummated in accordance with its terms, K1 (through Topco) may take certain actions to further stabilize MariaDB’s financial position including (i) making an up to $23 million additional equity investment in MariaDB and (ii) equitizing, cancelling or otherwise eliminating the RPV Note.

If the Offer is consummated, the interest of the K1 Group in MariaDB’s net book value and net earnings would be proportionate to the number of MariaDB Shares acquired in the Offer. If the Buy Out is consummated, the K1 Group’s interest in such items would further increase to 100%, and the K1 Group would be entitled to all benefits resulting from that interest, including all income generated by MariaDB’s operations and any future increase in MariaDB’s value. If the Unlisted Unit Alternative is available and elected by some or all MariaDB Shareholders, such former MariaDB Shareholders will share in a portion of the interest in MariaDB’s net book value and net earnings, and the benefits resulting from that interest. Former MariaDB Shareholders who elect for the Cash Offer would, upon closing of the Offer, have no opportunity to participate in the earnings and growth of MariaDB and would not have any right to vote on corporate matters. Similarly, after the Offer and, if applicable, the Buy Out, the K1 Group and, if the Unlisted Unit Alternative is available and elected for by some or all MariaDB Shareholders, such former MariaDB Shareholders, would also bear the risk of losses generated by MariaDB’s operations and any decrease in the value of MariaDB, and those former MariaDB Shareholders who elected the Cash Offer would not face the risk of losses generated by MariaDB’s operations or decline in the value of MariaDB.

Although we do not believe that net book value is a relevant measure, solely because the same is required for purposes of complying with the requirements of Rule 13e-3 and related rules under the Exchange Act we have set out the below information relating to net book value.

Assuming all MariaDB Shareholders elect for the Cash Offer, if the Offer and subsequent Buy Out is completed, all of the equity interests in MariaDB will be beneficially owned, indirectly through Bidco, by the K1 Group. Assuming all MariaDB Shareholders elect for the Unlisted Unit Alternative (and are eligible to do so), if the Offer and subsequent Buy Out is completed, 85% of the equity interests in MariaDB will be beneficially owned, indirectly through Bidco, by the K1 Group.

The table below sets forth the interests in MariaDB’s net book value and net earnings of the K1 Group immediately after the Offer and subsequent Buy Out, based on MariaDB’s net book value at 31 March 2024 and net earnings for the nine months ended 31 March 2024, as if the Offer and the Buy Out were each completed on such date.

The MariaDB Board has, as required under the Irish Takeover Rules, due to conflicts of interest, recused itself from taking part in the formulation and communication of advice on the Offer to MariaDB Shareholders. Instead, IBI Corporate Finance, which has been appointed as independent financial advisor to MariaDB under Rule 3 of the Irish Takeover Rules, has, in that capacity, taken responsibility for considering the Offer and formulating an appropriate recommendation to be made to MariaDB Shareholders.

As described in the Firm Announcement and as is expected to be described in the First Response Circular/Schedule 14D-9, IBI Corporate Finance has concluded, in the context of the background to and reasons for recommending the Cash Offer set out therein that the terms of the Cash Offer are fair and reasonable and it would recommend that MariaDB Shareholders should accept the Cash Offer.

IBI Corporate Finance has stated that it is unable to advise as to whether or not the financial terms of the Unlisted Unit Alternative are fair and reasonable. This is because IBI Corporate Finance has not had any involvement in the development and validation of any financial projections for Topco. As a result, IBI Corporate Finance is unable to assess any plans Topco may have for the development of MariaDB or the Topco Group to the degree necessary to form an assessment of the value of the Unlisted Unit Alternative.

A description of the reasons for IBI Corporate Finance’s approval of the Cash Offer is set forth in the First Response Circular/Schedule 14D-9. All shareholders should carefully read the information set forth in the First Response Circular/Schedule 14D-9.

Under the SEC rules governing “going-private” transactions, each K1 Filing Party may be deemed to be an affiliate of MariaDB and, therefore, required to disclose certain information and express their belief as to certain matters to MariaDB’s “unaffiliated security holders,” as defined under Rule 13e-3 of the Exchange Act (the “Unaffiliated Security Holders”). The K1 Filing Parties are making the statements in this “Special Factors” section solely for purposes of complying with the requirements of Rule 13e-3 and related rules under the Exchange Act. However, the view of the K1 Filing Parties as to the fairness of the Offer is not intended to be and should not be construed as a recommendation to any MariaDB Shareholder as whether they should tender their MariaDB Shares into the Offer. The K1 Filing Parties have interests in the Offer that are different from, and/or in addition to, the Unaffiliated Security Holders, as described elsewhere in this Offer Document.

Other than the estimate of value by Lazard Frères of the Unlisted Unit Alternative required by Rule 24.11 of the Irish Takeover Rules, the K1 Filing Parties have not performed, or engaged a financial advisor to perform, any valuation or other analysis for the purposes of assessing the fairness of the Offer to the Unaffiliated Security Holders. However, we believe that the Offer, and the price per MariaDB Share to be paid in the Offer (i.e., the payment of US$0.55 per MariaDB Share in the Cash Offer, without interest and less any required withholding taxes, or the value of the Topco Rollover Units (if issued) for those that elect the Unlisted Unit Alternative), is substantively and procedurally fair to the Unaffiliated Security Holders. We base our belief on, among other things, the following factors, each of which, in our judgment, supports the view as to the fairness of the Offer:

We also considered the following uncertainties, risks and potentially countervailing factors in our consideration of the fairness of the terms of the Offer:

We did not find it practicable to assign, nor did we assign, relative weights to the individual factors considered in reaching our conclusion as to fairness. K1 and Bidco’s financial advisor, Lazard, was not asked to and has not delivered, and will not deliver, a fairness opinion to us or any other person in connection with the Offer.

In reaching our conclusion as to fairness, we did not consider the liquidation value or net book value of MariaDB. The liquidation value was not considered because MariaDB (following the purchase of the RPV Note) is a viable going concern and we have no plans to liquidate MariaDB. Therefore, we believe that the liquidation value of MariaDB is irrelevant to a determination as to whether the Offer is fair to Unaffiliated Security Holders. Further, we did not consider net book value, which is an accounting concept, as a factor because we believe that net book value is not a material indicator of the value of MariaDB as a going concern because it is indicative of historical costs, and therefore is irrelevant to a determination as to whether the Offer is fair to the Unaffiliated Security Holders. We are not aware of any firm offers made by a third party to acquire MariaDB during the past two years (other than the statements of Progress Software Corp. and Runa Capital II (GP) regarding their respective possible offers for MariaDB Shares, each of which did not result in a firm offer). Third-party offers were not considered in reaching our conclusion as to fairness. If the Offer is consummated, the K1 Group intends to retain all MariaDB Shares so acquired in the Offer.

The foregoing discussion of the information and factors considered and given weight by us is not intended to be exhaustive and is not presented in any relative order of importance, but includes the factors considered by us that we believe to be material. Our view as to the fairness of the Offer to the Unaffiliated Security Holders should not be construed as a recommendation to any MariaDB Shareholder as to whether that shareholder should tender MariaDB Shares in the Offer. The K1 Filing Parties attempted to negotiate the terms of a transaction that would be most favourable to them, and not to the Unaffiliated Security Holders, and, accordingly, did not negotiate the terms of the Offer with a goal of obtaining terms that were fair to the Unaffiliated Security Holders.

IBI determined that the Cash Offer was fair and in the best interests of MariaDB and the Unaffiliated Security Holders as described in “Item 4. The Solicitation or Recommendation” of the First Response Circler/Schedule 14D-9 and “Item 8. Fairness of the Transaction” of the Schedule 13E-3 filed by the Company with the SEC.

If the executive officers and directors of the Company tender their MariaDB Shares for purchase pursuant to the Offer, they will receive the same opportunity to select cash consideration or the Unlisted Unit Alternative on the same terms and conditions as the other MariaDB Shareholders.

The following table sets forth (1) the number of MariaDB Shares beneficially owned as of 16 May 2024, by each of the Company’s executive officers and directors and (2) the aggregate cash consideration that would be payable for such MariaDB Shares, based on an offer price of US$0.55 per MariaDB Share (assuming the Cash Offer was elected).

Immediately following the closing of the Offer, each outstanding stock option to purchase a MariaDB Share (the “Options”), whether vested or unvested, will be automatically cancelled and converted solely into the right to receive an amount in cash equal to (1) the total number of MariaDB Shares subject to the Option immediately prior to the closing of the Offer multiplied by (2) the excess, if any, of the Offer Price over the per share exercise price of such Option, without interest thereon and less applicable withholding taxes. For the avoidance of doubt, at the closing of the Offer, each Option with a per share exercise price equal to or greater than the Offer Price that is outstanding as of immediately prior to the closing of the Offer shall be cancelled without any consideration and shall be of no further force or effect.

Immediately following the closing of the Offer, each outstanding restricted stock unit with respect to MariaDB Shares (the “RSUs”), whether vested but not yet settled or unvested, will be automatically cancelled and converted solely into the right to receive an amount in cash equal in value to (1) the total number of MariaDB Shares subject to such RSU immediately prior to the closing of the Offer, multiplied by (2) the Offer Price, without interest thereon and less applicable withholding taxes.

While we intend to consummate the Buy Out as soon as practicable after consummation of the Offer, if the Offer is consummated but the Buy Out does not occur, the number of MariaDB Shareholders, and the number of MariaDB Shares that are still in the hands of the public, may be so small that there will no longer be an active or liquid public trading market (or possibly any public trading market) for MariaDB Shares held by MariaDB Shareholders other than the K1 Filing Parties. We cannot predict whether the reduction in the number of MariaDB Shares that might otherwise trade publicly would have an adverse or beneficial effect on the market price for, or marketability of, MariaDB Shares or whether such reduction would cause future market prices to be greater or less than the price paid in the Offer.

After the Offer has closed and as soon as it is appropriate and possible to do so, and subject to the Offer becoming or being declared unconditional in all respects, Bidco intends to cause MariaDB to apply for the

cancellation of the listing and trading of the MariaDB Shares on the NYSE. Such cancellation of the listing and trading of MariaDB Shares is likely to reduce significantly the liquidity and marketability of any MariaDB Shares with respect to which the Offer has not been accepted.

Additionally, under NYSE rules, if MariaDB fails to meet certain criteria, the MariaDB Shares could be involuntarily de-listed from the NYSE. Among such criteria are minimum thresholds for (i) the number of holders, (ii) the number of MariaDB Shares publicly held and (iii) the aggregate market value of the MariaDB Shares publicly held. Thus, if we purchase a sufficient number of MariaDB Shares in the Offer, the MariaDB Shares may no longer meet NYSE’s listing requirements, regardless of our intent to voluntarily de-list the MariaDB Shares from the NYSE.

If the NYSE were to delist the MariaDB Shares, it is possible that the MariaDB Shares would trade on another securities exchange or in the over-the-counter market and that price quotations for the MariaDB Shares would be reported by such exchange or other sources. The extent of the public market for the MariaDB Shares and availability of such quotations would, however, depend upon such factors as the number of holders and/or the aggregate market value of the publicly held MariaDB Shares at such time, the interest in maintaining a market in the MariaDB Shares on the part of securities firms, the possible termination of registration of the MariaDB Shares under the Exchange Act and other factors.

The MariaDB Shares are currently registered under the Exchange Act. Such registration may be terminated upon application by MariaDB to the SEC if the MariaDB Shares are neither listed on a national securities exchange nor held by 300 or more holders of record. Termination of registration of the MariaDB Shares under the Exchange Act would substantially reduce the information required to be furnished by MariaDB to MariaDB Shareholders and to the SEC and would make certain provisions of the Exchange Act no longer applicable to MariaDB, such as the requirements of Rule 13e-3 under the Exchange Act with respect to “going private” transactions. If registration of MariaDB Shares under the Exchange Act were terminated, the MariaDB Shares would no longer be eligible for quotation on NYSE. As soon as the requirements for termination of registration are met, the K1 Filing Parties intend to cause MariaDB to make a filing with the SEC to terminate registration of the MariaDB Shares under Section 12(g)(4) of the Exchange Act and to suspend MariaDB’s reporting obligations under Section 15(d) of the Exchange Act.

As further described below, on 24 April 2024, Runa Capital Fund II, L.P., Runa Capital II (GP), Runa Capital Opportunity Fund I, L.P., Runa Capital Opportunity I (GP) and Runa Ventures I Limited and Topco entered into that certain Loan Purchase Agreement pursuant to which Topco purchased from RPV all of RPV’s right, title, and interest in, to and under the RPV Note. The RPV Note entitles the holder thereof to appoint two directors to the Board of MariaDB. Following the purchase of the RPV Note, Michael Fanfant and Yakov “Jack” Zubarev resigned as directors of MariaDB with effect from completion of the acquisition of the RPV Note and George Mansour and Jordan Wappler were appointed to the board of MariaDB as the nominees of the new holder of the RPV Note.

On 24 April 2024, RPV, as Agent under, and as defined in the RPV Note and Topco entered into that certain Agency Resignation and Assignment Agreement, pursuant to which, among other things, RPV resigned as Agent under the RPV Note (in such capacity, “Resigning Agent”) and Topco succeeded Resigning Agent as Agent under the RPV Note (in such capacity, “Successor Agent”). Pursuant to the Agency Resignation and Assignment Agreement, at the Effective Time or promptly thereafter, Resigning Agent (i) delivered all Collateral (as defined in the RPV Note) constituting all certificated equity securities that are in the possession of Resigning Agent to Successor Agent; (ii) executed documents necessary to assign its security interest in patents, trademarks and copyrights; (iii) executed documents of assignment with respect to all deposit account control agreements in effect; and (iv) entered into the Irish law Debenture Administrative Agent Substitution Deed.

The Irish law Debenture Administrative Agent Substitution Deed was entered into in respect of the debenture dated 10 October 2023 between RPV (as the administrative agent) and MariaDB (as chargor) (the “Debenture”) pursuant to which MariaDB created security interests over the undertaking and assets of MariaDB in favour of RPV, who held the benefit of the security interests created pursuant to the Debenture on trust for each of the Secured Parties (as defined in the Debenture). The purpose of the Debenture was to secure all liabilities, indebtedness and obligations (monetary (including post-petition interest, costs, fees, expenses and other amounts, whether allowed or not) or otherwise) of MariaDB under the RPV Note or any other document or instrument executed in connection therewith, in each case howsoever created, arising or evidenced, whether direct or indirect, absolute or contingent, or due or to become due. Pursuant to the Irish law Debenture Administrative Agent Substitution Deed, (i) RPV appointed Topco as the trustee of the trust in the place of RPV, (ii) RPV resigned as the administrative agent appointed under the RPV Note and the Debenture and (iii) RPV assigned and transferred absolutely to Topco all its present and future rights, title, interests, powers, authorities, discretions and indemnities in, amongst others, the Debenture. As such, Topco is party to the Debenture and holds the benefit of the secured assets created pursuant to the Debenture.

On 24 April 2024, MariaDB USA, Inc., RPV, Bank of America, N.A. and Topco entered into that certain Assignment of Deposit Account Control Agreement, pursuant to which RPV assigned to Topco all of RPV’s rights, titles, interests, duties, liabilities and obligations as secured party under the Amended and Restated Deposit Account Control Agreement, dated as of 23 February 2024, to evidence Topco’s security interest in certain deposit account(s) and the funds deposited therein.

On 24 April 2024, RPV and Topco entered into that certain Notice of Succession of Agency and Assignment of Security Interest in Patent Rights, pursuant to which RPV assigned to Topco each of the liens and security interests pledged, collaterally assigned, mortgaged, transferred and granted to, or otherwise created in favor of, RPV under the Patent Security Agreement, dated as of 10 October 2023 in, to and under the Patent Collateral (as defined in the Patent Security Agreement).

On 24 April 2024, RPV, Topco, and, solely for the limited purposes set forth therein, each of Runa Capital II (GP), a Cayman Islands exempted company (“Runa Capital II”), Runa Capital Opportunity I (GP), a Cayman Islands exempted company (“Runa Capital Opportunity”), and Runa Ventures Limited, a Bermuda company (together with Runa Capital II and Runa Capital Opportunity, the “Runa Loan Entities”), entered into that certain Loan Purchase Agreement (the “Loan Purchase Agreement”), filed as Exhibit (d)(2) to the Schedule TO and is incorporated herein, by reference pursuant to which, among other things, Topco purchased from RPV, on such date, all of RPV’s obligations, liabilities, right, title, and interest, in, to and under the RPV Note for $66,852,043.40 in cash.

Mutual Release and Covenants Not to Sue

Effective as of the closing of the purchase of the RPV Note, each of RPV and the Runa Loan Entities, on the one hand, and Topco, on the other hand, on behalf of themselves and certain of their related parties (as described further in the Loan Purchase Agreement), unconditionally and irrevocably released the other party (or parties, as the case may be) and certain of their related parties (as described further in the Loan Purchase Agreement, and including, in the case of the release given by RPV and the Runa Loan Entities, MariaDB and its subsidiaries) from, among other things, all claims, liabilities and causes of action of any kind or nature to the extent arising out of, in connection with, or relating to (i) RPV’s ownership of the RPV Note or status as a holder or note holder thereunder and/or an agent under the RPV Note or any related documents (except, in the case of the release given by Topco, other than any claims against RPV or any Runa Loan Entity pursuant to the Loan Purchase Agreement, which claims were not released) or (ii) any act or omission, error, negligence, breach of contract, tort, violation of law, matter or cause whatsoever arising from, in connection with, or relating to the RPV Note Documents (as defined in the Loan Purchase Agreement) or the transactions contemplated thereby.

Notwithstanding the preceding paragraph, the claims released by RPV, the Runa Loan Entities and certain of their related parties did not include any right or claim of (i) any of them, or increase or expand the obligations of any of them, under or pursuant to any indemnification, exculpation, expense advancement or other rights that any of them may be entitled to, solely in their capacity as a manager, director or officer of MariaDB or any of its subsidiaries, pursuant to applicable law, the organizational documents of MariaDB or any of its subsidiaries, any existing directors’ and officers’ liability insurance policy as in effect on the Closing Date or any replacement of such policy, or certain indemnification agreements entered into by and between MariaDB USA, Inc., on the one hand, and each of the Runa directors, on the other hand, (ii) RPV against Topco pursuant to the Loan Purchase Agreement or (iii) any rights that any of them may have pursuant to Section 37 and Section 38 of the RPV Note (collectively, the “Preserved Claims”).

In addition to the mutual releases described above, each of RPV and the Runa Loan Entities, on the one hand, and Topco, on the other hand, on behalf of themselves and certain of their related parties (as described in the Loan Purchase Agreement), covenanted not to (and to cause their related parties not to) sue or bring, assert or otherwise pursue any allegation, claim, proceeding or other action against the other party (or parties, as the case may be) and certain of their related parties (as described in the Loan Purchase Agreement, and including, in the case of the covenant of RPV and the Runa Loan Entities, MariaDB and its subsidiaries) on the basis of any matters released, regardless of whether such allegation, claim, proceeding or other action is enforceable under, or not prohibited by, applicable law or otherwise.

Non-Interference

Under the terms of the Loan Purchase Agreement, RPV and the Runa Loan Entities, on behalf of themselves and certain of their related parties (as described in the Loan Purchase Agreement), agreed that until the earlier of the date that (x) is three years after the date of the Loan Purchase Agreement and (y) (1) no amounts are due or payable under the RPV Note or any other Note document to Topco or any permitted assignee that is an affiliate of Topco, (2) any person, other than Topco or any of its related parties (as described in the Loan Purchase Agreement) that constitute a group as defined under Rule 13d-5(b)(1) promulgated under the Exchange Act, acquires relevant securities or other equity securities of MariaDB representing more than fifty percent (50%) of the outstanding debt or equity interests in MariaDB and its subsidiaries and (3) neither Topco nor any of its related parties holds any debt or equity interest in MariaDB and its subsidiaries (such period, the “Restricted Period”), they shall not and shall cause such other persons not to, directly or indirectly through any other person (i) object to, challenge, or commence any legal proceedings against Topco or certain of its related parties with respect to their acquisition of debt or equity securities in MariaDB or any of its subsidiaries (collectively, the “Contemplated Transactions”), (ii) engage in any action that would reasonably be expected to adversely interfere with, impede, delay, or otherwise affect Topco’s or one of its affiliates’ consummation of any Contemplated Transaction (including by acting alone or in concert with others to seek representation on or to control or influence the management, board of directors or policies of MariaDB or its subsidiaries) (but, without limiting any and all Preserved Claims), (iii) solicit, initiate or knowingly encourage any proposal or offer to MariaDB or its subsidiaries that constitutes or would reasonably be expected to lead to an alternative transaction to any Contemplated Transaction with a person other than Topco or one of its affiliates, (iv) initiate or participate in any communication with third parties with the intention of discouraging or dissuading them from proceeding with any transaction with Topco or one of its affiliates with respect to the debt or equity securities of MariaDB or its subsidiaries, (v) enter into any agreement, purchase agreement, letter of intent, tender agreement, or similar agreement with respect to an alternative transaction to a Contemplated Transaction involving a person other than Topco or one of its affiliates, (vi) effect or seek, offer or propose (whether publicly or otherwise) to effect, or participate in, knowingly facilitate or knowingly encourage any other person to effect or seek, offer or propose (whether publicly or otherwise) to effect or participate in, any acquisition of any equity interest (or beneficial ownership thereof), or rights or options to acquire any equity interest (or beneficial ownership thereof), any material assets, or any indebtedness or businesses of MariaDB or any of its subsidiaries, or (vii) take any action that would reasonably be expected to result in a request by a court of competent jurisdiction or a governmental authority to disclose, or would reasonably be expected to cause or require Topco, MariaDB or any of their respective related parties to disclose or make a public announcement regarding, any Confidential Information (as defined in the Loan Purchase Agreement) or any matter of the type set forth above.

Notwithstanding the preceding paragraph, none of RPV, any Runa Loan Entity nor any of their related parties (as described in the Loan Purchase Agreement) shall be prevented from disposing of any equity securities of

MariaDB after 31 December 2024 or from taking any actions in furtherance thereof, including the solicitation of purchasers for such equity securities (unless the failure by Topco or any of its related parties to acquire such equity securities prior to 31 December 2024 was caused, in any material respect, by the failure of any such person to comply with the restrictions set forth in the preceding paragraph).

Under the terms of the Loan Purchase Agreement, during the Restricted Period, subject to a carve-out for certain actions of portfolio companies, RPV and the Runa Loan Entities, on behalf of themselves and certain of their related parties (as described in the Loan Purchase Agreement), agreed not to, for themselves or on behalf of another person (i) (x) directly or indirectly solicit for employment or knowingly encourage any employee, consultant, adviser, or independent contractor of MariaDB or its subsidiaries who was employed, hired or engaged by MariaDB or its subsidiaries immediately prior to the closing to leave the employment, service relationship or engagement of MariaDB or its subsidiaries, or in any way knowingly interfere adversely with the relationship between MariaDB or its subsidiaries and any such employee, consultant, adviser, or independent contractor who was an employee, consultant, adviser, or independent contractor of MariaDB or its subsidiaries as of the Closing or (y) employ, hire or engage any such person who is or was, at any time within 12 months of such proposed employment, hiring or engagement, employed, hired or engaged by MariaDB or its subsidiaries (provided that the foregoing restriction does not prohibit RPV, the Runa Loan Entities or their related parties from engaging in solicitations for employees, consultants, advisers or independent contractors, so long as such solicitations are general in nature, do not specifically target employees, consultants, advisers or independent contractors of MariaDB or its subsidiaries, and do not result in the employment or engagement of such persons who respond to such general solicitations), (ii) intentionally and actively induce any specific customer, supplier, licensor, licensee, vendor, lessor or other material business relation of MariaDB or its subsidiaries as of the Closing (each a “Business Relation”) to cease doing business with, or otherwise modify adversely the business done with, MariaDB or its subsidiaries or (iii) in any way knowingly and intentionally interfere with the relationship between any specific Business Relation and MariaDB or its subsidiaries that is in effect as of the Closing.

In addition, subject to a carve-out for certain actions of portfolio companies, during the Restricted Period, RPV and the Runa Loan Entities, on behalf of themselves and certain of their related parties (as described in the Loan Purchase Agreement), agreed not to, directly or indirectly, for themselves or on behalf of another person (i) (1) create, develop or otherwise produce or invest in (including by investing in any person but excluding, for clarity, charitable donations or contributions to, sponsorships or forums of and similar activities involving the MariaDB Foundation or any of its subsidiaries) any open source based SQL database that use or are forked from any portion of the existing source code of the MariaDB Foundation, MariaDB and/or its subsidiaries, including without limitation MySQL, and that are or would reasonably be expected to be competitive with the products or services provided by MariaDB and/or its subsidiaries as of the Closing or (2) use any portion of the existing source code of MariaDB Foundation, MariaDB and/or its subsidiaries as of the Closing to create, develop, or produce a competitive product or service to such products or services provided by MariaDB and its subsidiaries as of the Closing, or (ii) solicit Michael “Monty” Widenius for employment or any consultant, independent contractor or other engagement, or otherwise any commercial relationship, or employ or engage him in any such capacity, or otherwise enter into any commercial agreement or arrangement with him that adversely interferes in any material respect or would reasonably be expected to adversely interfere in any material respect with the relationship between Mr. Widenius and MariaDB or any of its subsidiaries (provided that the foregoing restriction does not prohibit interactions between (x) on the one hand, RPV, the Runa Loan Entities and certain of their related parties (as described in the Loan Purchase Agreement), and, on the other hand, Mr. Widenius, that do not directly or indirectly relate to such employment, consulting, independent contractor or other commercial relationship or (y) on the one hand, Acronis AG, a company organized under the laws of Switzerland (“Acronis AG”), and, on the other hand, Mr. Widenius, so long as none of RPV, the Runa Loan Entities nor their related parties (in each case, other than Acronis AG) causes, directs or actively facilitates or encourages Acronis AG to take any action prohibited by the foregoing restrictions.

The foregoing summary describes the material terms of the Loan Purchase Agreement and is qualified in its entirety by the provisions of the Loan Purchase Agreement, a copy of which has been filed as Exhibit (d)(2) to the Schedule TO which this Offer Document is filed as an exhibit to.

The K1 Group has received irrevocable undertakings to accept the Offer, or, where Bidco and/or the K1 Group elects to switch to a scheme of arrangement with respect to MariaDB under the Companies Act 2014, vote in favour of the scheme of arrangement under the Companies Act 2014, in respect of, in aggregate, 47,402,907 MariaDB Shares, representing in aggregate approximately 68.67% of the existing issued share capital of MariaDB as of 16 May 2024.

These undertakings continue to be binding in the event of a competing offer for MariaDB.

Further details of these irrevocable undertakings (including the circumstances in which they may lapse) are set out below:

Save in respect of the irrevocable undertakings received from Intel Capital Corporation and each of the Runa Equity Holders, each of the irrevocable undertakings shall lapse and cease to have any effect on and from the earliest of the following occurrences:

The irrevocable undertakings received from Intel Capital Corporation and each of the Runa Equity Holders shall lapse and cease to have any effect on and from the earliest of the following occurrences:

No appraisal rights under the Irish Takeover Rules or the Companies Act 2014 will be available to holders of MariaDB Shares with respect to the Offer.

Except as set forth elsewhere in this Offer Document: (i) none of the K1 Group beneficially owns or has a right to acquire any MariaDB Shares or any other equity securities of MariaDB; (ii) none of the K1 Group members has effected any transaction in the MariaDB Shares or any other equity securities of MariaDB during the 60 days prior to the date of this Offer Document; (iii) none of the K1 Group members has any contract, arrangement, understanding or relationship with any other person with respect to any securities of the Company (including, but not limited to, any contract, arrangement, understanding or relationship concerning the transfer or the voting of any such securities, joint ventures, loan or option arrangements, puts or calls, guaranties of loans, guaranties against loss or the giving or withholding of proxies, consents or authorizations); (iv) during the two years before the date of this Offer Document, there have been no transactions between any K1 Group member, on the one hand, and MariaDB or any of its executive officers, directors or affiliates, on the other hand, that would require reporting under SEC rules and regulations, other than as so reported; (v) during the two years before the date of this Offer Document, there have been no contacts, negotiations or transactions between any K1 Group

member, on the one hand, and MariaDB or any of its subsidiaries or affiliates, on the other hand, concerning a merger, consolidation or acquisition, a tender offer or other acquisition of securities, an election of directors or a sale or other transfer of a material amount of assets; (vi) none of the K1 Group members has been convicted in a criminal proceeding during the past five years (excluding traffic violations or similar misdemeanors); (vii) neither Mr. Mansour or Mr. Wappler, in their capacities as directors of MariaDB, has made a recommendation either in support of or in opposition to the Offer and (viii) none of K1 Group members has been a party to any judicial or administrative proceeding during the past five years that resulted in a judgment, decree or final order enjoining that person from future violations of, or prohibiting activities subject to, federal or state securities laws or a finding of any violation of federal or state securities laws.

Each of the directors and executive officers of MariaDB will make individual determinations regarding whether to tender their MariaDB Shares in the Offer based upon certain factors and reasons each of them deem individually relevant. MariaDB has informed us that, to the knowledge of MariaDB after reasonable inquiry, each executive officer, director and affiliate of MariaDB who holds MariaDB Shares currently intends, subject to compliance with applicable law, including Section 16(b) of the Exchange Act, to tender all MariaDB Shares held of record or beneficially owned by such person or entity in the Offer. Smartfin and Mr. Ingels have given irrevocable undertakings to accept the Offer and to elect in full for the Unlisted Unit Alternative.

The K1 Group has received irrevocable undertakings to accept the Offer, or, where Bidco and/or the K1 Group elects to switch to a scheme of arrangement with respect to MariaDB under the Companies Act 2014, vote in favour of the scheme of arrangement under the Companies Act 2014, in respect of, in aggregate, 47,402,907 MariaDB Shares, representing in aggregate approximately 68.67% of the existing issued share capital of MariaDB as of 16 May 2024.

On 24 April 2024, the Runa Capital Fund II, L.P., Runa Capital II (GP), Runa Capital Opportunity Fund I, L.P., Runa Capital Opportunity I (GP) and Runa Ventures I Limited and Topco entered into that certain Loan Purchase Agreement pursuant to which Topco purchased from RPV all of RPV’s right, title, and interest in, to and under the RPV Note. The consideration paid by Topco to RPV for the RPV Note was approximately $62.4 million, plus approximately $4.5 million comprised of accrued interest under the RPV Note and the transaction expenses of RPV. The RPV Note entitles the holder thereof to appoint two directors to the board of MariaDB. Following the purchase of the RPV Note, Michael Fanfant and Yakov “Jack” Zubarev resigned as directors of MariaDB with effect from completion of the acquisition of the RPV Note and George Mansour and Jordan Wappler were appointed to the board of MariaDB as the nominees of the new holder of the RPV Note.

The financial interests of K1 and BidCo with regard to the Cash Offer are generally adverse to the financial interests of the MariaDB Shareholders being asked to tender their MariaDB Shares. Even for those MariaDB Shareholders who elect to receive the Unlisted Unit Alternative, the Topco Rollover Units have fewer rights than the voting Class A units of Topco held by the K1 Group. See the summary of the Topco LLCA included in Appendix 2.

The MariaDB Shareholders being asked to tender their MariaDB Shares should be aware that the executive officers and certain directors of the Company have interests in connection with the Offer that present them with actual or potential conflicts of interest. A description of these interests, including the information required to be disclosed pursuant to Item 402(t) of Regulation S-K, is included in the First Response Circular/Schedule 14D-9 under the heading “Item 3—Past Contacts, Transactions, Negotiations and Agreements,” which description and information are incorporated herein by reference.

In considering the fairness of the consideration to be received in the Offer, MariaDB Shareholders should be aware that K1 and its affiliates (including Topco and Bidco) have certain current actual or potential conflicts of interest in connection with the Offer, notably Topco’s ownership of the RPV Note (and its status as MariaDB’s largest creditor as a result thereof). In addition, certain of K1’s employees are also directors of MariaDB, as further described in the First Response Circular/Schedule 14D-9.

You should be aware that aside from their interests as MariaDB Shareholders, the directors and executive officers of the Company may be considered to have interests in the Offer that are different from, or in addition to, those of other shareholders generally. In particular, two of the Company’s directors—George Mansour and Jordan Wappler—are currently employees of K1 and its affiliates.

The Offer is not subject to any financing condition. The cash consideration is being funded through existing resources of K5, which are to be invested by them to fund Bidco pursuant to the Equity Commitment Letter.

Assuming all MariaDB Shareholders elect for the Cash Offer, the cash consideration payable by Bidco to MariaDB Shareholders, in the aggregate, for all outstanding MariaDB Shares will be approximately $39.9 million as of 16 May 2024.

Total fees and expenses incurred or to be incurred by Bidco in connection with the Offer are estimated as of 16 May 2024 to be as follows:

To holders of MariaDB Shares

Dear Shareholder

On 24 April 2024, Bidco made the Firm Announcement. I am writing to you to explain the terms of the Offer, the background to and reasons for making the Offer and the procedures by which you can accept it.

Bidco hereby offers to acquire the entire issued and to be issued share capital of MariaDB on the terms, and subject to the conditions, set out in this Offer Document and in the Acceptance Documents. The Offer values the entire issued and to be issued share capital of MariaDB at approximately US$39.9 million.

MariaDB Shareholders may elect to exchange their MariaDB Shares for (i) the Cash Offer or (ii) in respect of all (but not some) of their MariaDB Shares, one unlisted, unregistered non-voting Class B unit of Topco (each, a “Topco Rollover Unit”) for each MariaDB Share (the “Unlisted Unit Alternative”), subject to the provisions (including with respect to proration) described in paragraph 7 of Part 2 of Appendix 1.

Pursuant to the Cash Offer, MariaDB Shareholders may elect, in respect of their MariaDB Shares, to receive the Cash Offer.

The Cash Offer is fully financed, cash confirmed and not conditional on due diligence.

As an alternative to the Cash Offer, Eligible MariaDB Shareholders may elect, in respect of all (but not some) of their MariaDB Shares, to receive, in lieu of the Cash Offer to which they are otherwise entitled, the Unlisted Unit Alternative, with such Topco Rollover Units to be issued on the terms and pursuant to the mechanism described in paragraph 7 of Part 2 of Appendix 1. In aggregate, the maximum number of Topco Rollover Units available to be issued to Eligible MariaDB Shareholders under the Unlisted Unit Alternative is limited to 15% of Topco’s fully diluted share capital (after issuance of all Topco Rollover Units to all Electing Shareholders) (the “Rollover Threshold”), or 39,729,622 Topco Rollover Units. It is a condition to the Unlisted Unit Alternative that the Topco Rollover Units to be offered and sold may be issued pursuant to an exemption from registration under the Securities Act and an exemption from the registration requirements of applicable US state securities laws. The key terms of the Unlisted Unit Alternative are summarised in paragraphs 7.1-7.3 of Part 2 of Appendix 1 of this Offer Document. Further details regarding Topco and the rights of the Topco Rollover Units are set out paragraphs 7.4-7.8 of Part 2 of Appendix 1 of this Offer Document.

MariaDB provides a mission critical product offering that occupies a strong position within the relational database market with an impressive global customer base across multiple industry sectors.

Having followed the development of the business through time, K1 believes that the Offer for MariaDB is an attractive opportunity given:

Furthermore, as a private company, MariaDB would be able to benefit from a number of advantages including:

Furthermore, MariaDB’s business model and product portfolio aligns with K1’s mandate and proven track record of investing in enterprise software companies providing mission critical products and services with high recurring revenues, strong retention rates and diversified customer bases. Finally, K1’s operating affiliate, K1 Operations LLC, has a strong track record of supporting management teams in executing operationally focused strategies designed to support the growth, development and profitability of their partner companies.

MariaDB has been in financial distress for an extended period of time, which most recently culminated in the failure to repay the RPV Note initially granted on 10 October 2023. This uncertainty has been reflected in the MariaDB share price which had traded at an average closing share price of $1.07 between 20 March 2023 (3 months post IPO) and 18 August 2023 (inclusive), before declining significantly and closing at $0.19 on 5 February 2024.

As a result, Bidco believes that the Offer not only delivers a compelling value proposition for MariaDB Shareholders but also represents a relatively certain path forward to realize shareholder value. In summary, the Offer represents:

Finally, K1 and affiliated entities have also acquired the RPV Note which will in turn remedy the current insolvency position of MariaDB in the short-term and ensure the business is put into a sound financial position and in turn make the proposed acquisition viable.

The K1 Group has received irrevocable undertakings to accept the Offer, or, where Bidco and/or the K1 Group elects to switch to a scheme of arrangement with respect to MariaDB under the Companies Act 2014, vote in favour of the scheme of arrangement under the Companies Act 2014, in respect of, in aggregate, 47,402,907 MariaDB Shares, representing in aggregate approximately 68.67% of the existing issued share capital of MariaDB as of 16 May 2024.

K1 is a global investment firm that builds category-leading enterprise software companies and has over $14.9 billion of assets under management. K1 partners with strong management teams of high growth technology businesses to help them achieve successful outcomes. With over 115 professionals, K1 and its

operating affiliate, K1 Operations LLC, change industry landscapes with operationally focused growth strategies designed to rapidly scale portfolio companies. Since the inception of the firm, K1 has partnered with over 225 enterprise software companies including industry leaders such as Axcient, Checkmarx, Emburse, Elmo, Granicus, Litera Microsystems, Onit, Reveal-Brainspace, simPRO, Smarsh, and XTM International.

Bidco is a newly formed limited liability company formed in Delaware for the purposes of the Offer and is indirectly wholly owned by K5. Bidco has not traded since its formation, nor has it entered into any obligations, other than in connection with the Offer. The current officers of Bidco are Sujit Banerjee (as President) and Henry Wang (as Secretary).

Topco is a newly formed limited liability company formed in Delaware for the purposes of the Offer and the acquisition of the RPV Note and is directly wholly owned by K5. Topco has not traded since its formation, nor has it entered into any obligations, other than in connection with the Offer and the acquisition of the RPV Note. The current officers of Topco are Sujit Banerjee (as President) and Henry Wang (as Secretary).

Further information on Bidco is set out in paragraph 2 of Appendix 5.

MariaDB, headquartered in California and listed on the NYSE, is a new generation database company whose products are used by companies big and small, reaching more than a billion users through Linux distributions, downloaded over one billion times, and used across all types of use cases and industries. Deployed in minutes and maintained with ease, MariaDB database products are engineered to support any workload and any scale – all while saving up to 90% of proprietary database costs. MariaDB’s software is the backbone of critical services that people rely on every day.

The cash consideration payable by Bidco pursuant to the Offer is being funded through existing resources of K5, which are to be invested by them to fund Bidco pursuant to the Equity Commitment Letter.

Lazard & Co., Limited, acting as financial adviser to K1 and Bidco, is satisfied that sufficient resources are available to Bidco to enable it to satisfy in full the cash consideration payable under the terms of the Offer.

Please see paragraph 3 of Appendix 5 for further information on the financing of the Offer.

Following completion of the Offer, K1 and Bidco intend to work closely with MariaDB in accelerating investment in organic growth opportunities, identifying inorganic growth opportunities to expand the overall size, scale and reach of MariaDB’s solutions and product portfolio as well as focusing on key operational initiatives to position the company for sustainable long-term growth. K1’s emphasis on value-added and long term partnership with MariaDB and focus on sustainable growth and innovation will allow the company to gain several strategic advantages, particularly in a private company context. Such benefits include: (i) the ability to prioritize long term objectives, (ii) greater operating flexibility and ability to more swiftly adapt to market changes and pursue opportunities that align with its long-term vision and (iii) support from a capital partner with over $14.9 billion in assets under management with operational and financial resources to help the company achieve its potential.

If the Offer is consummated in accordance with its terms, K1 (through Topco) may take certain actions to further stabilize MariaDB’s financial position including (i) making an up to $23 million additional equity investment in MariaDB and (ii) equitizing, cancelling or otherwise eliminating the RPV Note.

MariaDB has a team of passionate and talented employees who have worked hard to develop a robust set of products and services that today serve an impressive global customer base. K1 and Bidco intend to accelerate growth, allow high potential employees to develop their own careers and in turn enable the company to realize its full potential.

Following completion of the Offer, K1 and Bidco intend to work with MariaDB’s senior management team to review the operating performance of the business and align on operational best practices to implement in order to accelerate MariaDB’s growth and operating profitability and over the long term, create greater employment opportunities for existing and prospective team members. Following completion of the Transactions, certain corporate functions which have historically been related to MariaDB’s status as a publicly traded company may no longer be required or may be reduced in size to reflect MariaDB ceasing to be a public company.

As of the date of this Offer Document, the result of the review is uncertain, and no firm decisions have been made by K1 and Bidco in relation to specific actions which may be taken. K1 and Bidco do not have any intention of making material changes to the balance of skills and functions of MariaDB and do not expect their review to result in a material headcount reduction in the aggregate once implemented. Any headcount reductions will be carried out in accordance with applicable law.

K1 and Bidco confirm that, where employees of MariaDB have existing employment rights, including pension rights, under applicable law, those rights and agreements will be fully safeguarded in accordance with applicable law following the Offer becoming unconditional to the extent valid and in good standing under applicable law and such underlying agreements are effective. K1 and Bidco look forward to working with MariaDB's employees, customers and other stakeholders following the completion of the Offer.

Following completion of the Offer, K1 and Bidco intend to review the management, governance and incentive structures of MariaDB. K1 and Bidco have not entered into, and have not agreed to nor memorialised any form of incentivisation arrangements with members of MariaDB’s management as of the date of this Offer Document, but may put in place incentive arrangements for certain members of the MariaDB’s management team following completion of the Offer when appropriate under applicable law. No discussions have taken place between K1 and MariaDB management to date in relation to management incentive arrangements.

K1 and Bidco do not have plans to change the locations of business, headquarters or headquarters functions of MariaDB and intend to defer to any such decisions that may have been made by existing management, if any. K1 and Bidco do not intend to redeploy the fixed assets of MariaDB but may, in the future, consider and implement strategic alternatives concerning certain assets owned by MariaDB and locations of the business and headquarters.

MariaDB Shares are currently listed on the NYSE. As set out in paragraph 11, as soon as it is appropriate and possible to do so, applications will be made for the deregistration of the MariaDB Shares under the US Exchange Act and delisting from the NYSE.

The Offer is being extended to any MariaDB Shares which are issued or unconditionally allotted and fully paid (or credited as fully paid) while the Offer remains capable of acceptance, including, without limitation, any MariaDB Shares issued pursuant to the exercise of options granted pursuant to the Employee Share Plans or pursuant to exercise of the Warrants.

Bidco will make appropriate proposals to MariaDB Optionholders and MariaDB Warrantholders. These proposals will be sent as soon as practicable following the date of this Offer Document and will be made subject to the Offer becoming or being declared unconditional in all respects.

If the Offer becomes or is declared unconditional in all respects and sufficient acceptances have been received at the Expiration Time (and in all cases within four months of the date of this document), following closing of the Offer, Bidco intends to apply the provisions of Sections 456 to 460 of the Companies Act 2014 to acquire compulsorily any outstanding MariaDB Shares not acquired or agreed to be acquired pursuant to the Offer or

otherwise. The default election for all MariaDB Shareholders during this compulsory acquisition process will be for the Cash Offer. Furthermore, if Bidco has exercised its Rollover Withdrawal Right, the Unlisted Unit Alternative will not be available to any MariaDB Shareholders during this compulsory acquisition process and each remaining MariaDB Shareholder will be deemed to have elected for the Cash Offer.

Notwithstanding the Offer being declared unconditional as to acceptances, Bidco and K1 also cannot guarantee that it will be in a position to carry out the Buy Out, including because the number of withdrawals during the Post Acceptance Unconditional Period may be such that Bidco may not have received sufficient acceptances at the Expiration Time to carry out the Buy Out under the provisions of Sections 456 to 460 of the Companies Act 2014. In addition, Bidco and K1 cannot guarantee that it will control MariaDB after the close of the Offer as the number of withdrawals during the Post Acceptance Unconditional Period may be such that Bidco may not have received sufficient acceptances at the Expiration Time to acquire control of MariaDB (e.g. 50%+ of the issued share capital of MariaDB). However, the K1 Group has received irrevocable undertakings to accept the Offer, or, where Bidco and/or the K1 Group elects to switch to a scheme of arrangement with respect to MariaDB under the Companies Act 2014, vote in favour of the scheme of arrangement under the Companies Act 2014, in respect of, in aggregate, 47,402,907 MariaDB Shares, representing in aggregate approximately 68.67% of the existing issued share capital of MariaDB as of 16 May 2024. The details of such irrevocable undertakings are set out in paragraph 6 “Disclosable Transactions” of the “Special Factors” section of this Offer Document.

After the Offer has closed and as soon as it is appropriate and possible to do so, and subject to the Offer becoming or being declared unconditional in all respects, Bidco intends to cause MariaDB to apply for the cancellation of the listing and trading of the MariaDB Shares on the NYSE. Such cancellation of the listing and trading of MariaDB Shares is likely to reduce significantly the liquidity and marketability of any MariaDB Shares with respect to which the Offer has not been accepted.

Bidco intends to take, or cause to be taken, all actions, and do or cause to be done all things, reasonably necessary, proper or advisable on its part under applicable law to cause the de-registration of the MariaDB Shares under the US Exchange Act as soon as practicable after such delisting.

Following deregistration of the MariaDB Shares under the US Exchange Act and delisting from the NYSE, Bidco intends to procure that MariaDB is re-registered as a private company under the relevant provisions of the Companies Act 2014.

The attention of MariaDB Shareholders is drawn to Appendix 6, which contains a summary, as a general guide only, of certain limited aspects of the Irish and US federal income taxation treatment of acceptance of the Offer. These summaries are not intended to be, and should not be construed to be, legal or taxation advice to any particular MariaDB Shareholder. Any MariaDB Shareholder who, or which, is in doubt as to his, her, or its position or who is subject to taxation in any jurisdiction other than Ireland or the United States is strongly recommended to consult his, her or its own independent professional advisers.

If you hold your MariaDB Shares directly as the holder of record, complete and sign the Letter of Transmittal (either manually or electronically) (or, in the case of a book-entry transfer, deliver an Agent’s Message in lieu of the Letter of Transmittal) that accompanies this Offer Document (which constitutes the form of acceptance for the Offer for the purposes of the Irish Takeover Rules) in accordance with the instructions set forth therein and mail or electronically deliver the Letter of Transmittal with any required signature guarantees and all other required documents to the Exchange Agent. These materials must be delivered to the Exchange Agent prior to the Expiration Time. See Part 3 of Appendix 1 for further details on the procedures for book-entry transfer.

If you hold your MariaDB Shares through a broker, dealer, commercial bank, trust company or other nominee, request your broker, dealer, commercial bank, trust company or other nominee to tender your MariaDB Shares through DTC’s Automated Tender Offer Program (“ATOP”) prior to the Expiration Time.

We are not providing for guaranteed delivery procedures. Therefore, MariaDB Shareholders must allow sufficient time for the necessary tender procedures to be completed during normal business hours.

The method of delivery of share certificates and all other required documents, including delivery through the Book-Entry Transfer Facility, is at the option and risk of the tendering MariaDB Shareholder, and the delivery will be deemed made only when actually received by the Exchange Agent. If delivery is by mail, registered mail with return receipt requested, properly insured, is recommended. In all cases, sufficient time should be allowed to ensure timely delivery.

WHILE YOU HAVE UNTIL THE EXPIRATION TIME TO COMPLETE YOUR TENDER, IF BIDCO CANNOT DETERMINE AT THE ACCEPTANCE UNCONDITIONAL TIME (AS IT MAY BE EXTENDED AS DESCRIBED HEREIN) THAT (I) THE ACCEPTANCE CONDITION HAS BEEN SATISFIED, FULFILLED OR, TO THE EXTENT PERMITTED, WAIVED, AND (II) ALL OTHER CONDITIONS WILL BE SATISFIED, FULFILLED OR, TO THE EXTENT PERMITTED, WAIVED BY THE EXPIRATION TIME, THE OFFER WILL LAPSE AND THERE WILL BE NO POST-ACCEPTANCE UNCONDITIONAL PERIOD. THEREFORE, MARIADB SHAREHOLDERS ARE STRONGLY ENCOURAGED TO TENDER THEIR MARIADB SHARES AS SOON AS POSSIBLE AND PRIOR TO THE ACCEPTANCE CUT-OFF TIME.

In addition, Eligible MariaDB Shareholders that wish to receive the Unlisted Unit Alternative will be required to (i) provide a completed Response Letter and (ii) following receipt of the Offering Memorandum (if applicable), a signature page to the Topco LLCA by the Expiration Time, as further described in Part 3 of Appendix 1. Failure to complete these additional requirements will result in the relevant Eligible MariaDB Shareholders that tender their MariaDB Shares being unable to receive the Unlisted Unit Alternative.

For further details on the procedure for tendering MariaDB Shares, please see Part 3 of Appendix 1.

IF YOU HAVE ANY QUESTIONS ABOUT THE PROCEDURE FOR TENDERING MARIADB SHARES, PLEASE CONTACT THE INFORMATION AGENT AT ITS TELEPHONE NUMBER SET FORTH ON THE FRONT OF THIS OFFER DOCUMENT.

The full text of all of the conditions to the Offer is set out in Part 1 of Appendix 1.

Any person that tenders MariaDB Shares will have the right to withdraw such MariaDB Shares at any time until the Expiration Time.

The Offer will not be deemed to have been accepted in respect of any MariaDB Shares which have been validly withdrawn.

This right of withdrawal is equally available to all MariaDB Shareholders.

Further details of this right of withdrawal and the procedure for effecting withdrawals are set out in paragraph 4 of Part 2 of Appendix 1.

Subject to the Offer becoming or being declared unconditional in all respects (except in the case of certain Overseas Shareholders (other than those resident in, or otherwise subject to the jurisdiction of, Ireland or the United States) as described in this Offer Document and save to the extent that the Irish Takeover Panel permits any extension of such period) by the Expiration Time (as it may be extended as described herein), settlement of the consideration to which accepting MariaDB Shareholders are entitled under the Offer will be effected promptly and no later than three Business Days after the Expiration Time.

Where an acceptance relates to MariaDB Shares in certificated or registered form, settlement of any cash consideration due will be sent by post (or such other method as may be approved by the Irish Takeover Panel) to the accepting holder or his, her or its appointed agent(s) whose name and address (outside a Restricted Jurisdiction) is set out in the relevant box in the Letter of Transmittal or, if none is set out, to the first named holder at his, her or its registered address (outside of a Restricted Jurisdiction). The cash consideration due will be paid in US dollars and will be effected by the issue of cheques.

Where an acceptance relates to MariaDB Shares in book-entry form held through the Book-Entry Transfer Facility, the cash consideration to which the accepting holder is entitled will be paid in US dollars and will be effected by means of a payment by the Exchange Agent to the Book-Entry Transfer Facility for credit to the account of the participant in the Book-Entry Transfer Facility that tendered the MariaDB Shares for further credit to the account of the accepting holder.

If the Offer lapses or is withdrawn, or if any tendered MariaDB Shares are not accepted for exchange for any reason pursuant to the terms and conditions of the Offer (including if the Offer lapses (i.e., expires before becoming unconditional in all respects)), or if certificates representing such shares are submitted representing more MariaDB Shares than are tendered, certificates representing unexchanged or untendered MariaDB Shares will be returned (by post or such other method as may be approved by the Irish Takeover Panel), without expense to the tendering shareholder (or, in the case of MariaDB Shares tendered by book-entry transfer into the Exchange Agent’s account at a Book-Entry Transfer Facility, such MariaDB Shares will be credited to an account maintained at such Book-Entry Transfer Facility), as soon as practicable and in any event within three Business Days following the lapse or withdrawal of the offer.

Your attention is drawn to the information set out in the rest of this Offer Document, including the appendices.

Yours faithfully,

For the purposes of the conditions in Appendix 1:

In the event that the Offer lapses in any circumstances, the Offer will cease to be capable of further acceptance and Bidco and accepting MariaDB Shareholders will thereupon cease to be bound by prior acceptances. If Bidco is required to make an offer for MariaDB Shares under the provisions of Rule 9 of the Irish Takeover Rules, Bidco may make such alterations to any of the above conditions as are necessary to comply with the provisions of that rule.

Bidco reserves the right for one or more subsidiaries of Bidco or another Affiliate owned by K1 from time to time to implement the acquisition of the MariaDB Shares with the prior written approval of the Irish Takeover Panel.

Bidco reserves the right, with the consent of the Irish Takeover Panel and MariaDB, to elect to implement the acquisition of the MariaDB Shares by way of a scheme of arrangement of MariaDB under the Companies Act 2014. In such event, the scheme of arrangement will be implemented on substantially the same terms, so far as applicable, as those which would apply to the Offer, subject to appropriate amendments (including to statutory voting requirements) to reflect the change in method of implementing the Offer.

Without prejudice to the terms of the Letter of Transmittal and the provisions of Parts 1 and 2 of this Appendix 1, by executing the Letter of Transmittal or delivering an Agent’s Message to the Exchange Agent:

The amended and restated limited liability company agreement of Topco (the “Topco LLCA”) will amend and restate that certain Limited Liability Company Agreement of Topco, dated as of 28 March 2024.

The Topco LLCA sets forth the rights and obligations of Topco’s members (the “Members”) with respect to their limited liability company interests in Topco. It also provides for, among other things, how Topco will be managed and dissolved and the treatment of certain tax matters. A summary of the material provisions of the Topco LLCA is set forth below. This summary has been included to provide potential investors in Topco with information regarding the terms of the Topco LLCA, but it does not purport to be and is not a complete summary of all terms, and it is qualified in its entirety by reference to the form of the final agreement, which has been filed as Exhibit (d)(6) to the Schedule TO and is incorporated herein by reference.

The Topco LLCA provides that limited liability company interests in Topco will be represented by units (“Units”). Units include Class A units, which shall have the right to vote on any action, approval or consent by the holders of Class A units to the extent such right is granted to them pursuant to the Topco LLCA, Class B units which, except for non-waivable rights (if any) expressly granted to the holders of such Units pursuant to Delaware law, shall have no voting rights, and any other Units created and authorized by Topco’s board of managers (“Board”). Topco will maintain a Unit ownership ledger setting forth, among other things, the name of each Member, the number of each class of Units they hold, and the capital contributions made by such Member.

The Topco LLCA also provides that, except as expressly provided therein, no Member will be entitled to withdraw any part of their capital contributions or receive any distribution from Topco.

Under the terms of the Topco LLCA, the Board will consist of three managers appointed by K5 (collectively, the “K1 Managers”), each of whom shall be entitled to three votes, and such other managers appointed from time to time by K5, each of whom shall be entitled to one vote. The K1 Managers will at all times hold a majority of the total votes of the Board, and K5 may elect to vest any one appointed K1 Manager with the vote or votes of any unappointed K1 Manager(s). The affirmative vote (whether by proxy or otherwise) of the managers holding at least a majority of the votes of all managers then serving on the Board shall be the act of the Board. Each manager will serve until a successor is appointed or their earlier resignation, death or removal. A manager may resign at any time by delivering written notice to Topco. Managers may be removed from the Board or any committee thereof only by K5.

The Board or K5 may approve one or more observers of the Board that shall (i) be entitled to attend meetings of the Board, but not vote and (ii) be entitled to receive all notices, information and reports as determined by the Board that are generally furnished by Topco to the Board, at the same time and in the same manner as furnished to the Board. Any such observer may be removed for any reason at any time by the Board or K5.

Topco will pay, or cause one of its subsidiaries to pay, the reasonable out of pocket costs and expenses incurred by each manager and any observer of the Board in the course of such person’s service, including in connection with attending regular and special meetings of the Board or any committee thereof. Such reimbursement will be subject to Topco’s and its subsidiaries’ policies and procedures with respect to reimbursements and any other limitations or conditions determined by the Board.

The Topco LLCA contains customary exculpation and indemnification provisions in respect of Topco’s managers and provides that, unless otherwise determined by the Board, Topco will maintain, at its or its subsidiaries’ expense, insurance to protect such persons against any expense, liability or loss against which they are so indemnified.

Pursuant to the Topco LLCA, except for any actions that expressly require the approval or consent of K5 or the Members thereunder, and notwithstanding anything to the contrary in the Delaware Limited Liability Company Act (the “Delaware Act”), the Board shall have the exclusive authority and power to, among other things: (i) conduct,

direct and exercise full control over all activities of Topco, including all decisions relating to the issuance, voting, sale and transfer of, and the exercise of other rights with respect to, securities of Topco’s subsidiaries; (ii) manage the business and affairs of Topco, including matters concerning (A) distribution of net profits, net losses and investment proceeds, including the taxes thereon, and (B) accounting procedures and determinations, tax determinations and elections; (iii) (A) bind or take any action on behalf of Topco and (B) exercise any rights and powers (including the rights and powers to take certain actions, give or withhold certain consents or approvals, or make certain determinations, opinions, judgments or other decisions) granted to Topco under the Topco LLCA or any other contract, instrument or agreement to which Topco is a party; (iv) (A) approve, on behalf of Topco and all of the Members, a Sale Transaction (defined below) in which Topco or any of its subsidiaries is the seller or any merger, consolidation or other transaction involving Topco, any of its subsidiaries or any of their assets, and to cause Topco to enter into any agreement regarding any Sale Transaction in which Topco or any of its subsidiaries is the seller or any merger, consolidation or other transaction involving Topco, any of its subsidiaries or any of their assets, (B) approve and structure an initial public offering, (C) determine the location of the principal and any other office of Topco, (D) cause Topco to transfer to, or domesticate or continue in any jurisdiction, and, in connection therewith, elect to continue its existence as a limited liability company, in the State of Delaware, (E) cause Topco to convert to a corporation or other entity, (F) cause Topco to create and issue Units (including other classes of Units having rights, powers or duties different from, senior to or more favorable than existing classes of Units) and to determine the consideration payable in connection with the issuance of Units, if any, and, in connection therewith, amend and restate the Topco LLCA to reflect such issuances and to make such other amendments as the Board deems necessary or desirable to reflect such issuances, (G) cause Topco to repurchase, redeem or otherwise acquire Units, (H) determine the fair market value of any Unit and the fair value of any assets of Topco, including any equity or debt securities of any subsidiary of Topco, in each case, taking into account all factors determinative of value that the Board deems relevant, (I) determine, as of any applicable time, any amounts contemplated to be determined or calculated in the Topco LLCA, (J) admit any person as a Member, (K) amend and restate the Topco LLCA, (L) permit certain persons to continue as Members notwithstanding certain provisions of the Delaware Act, and (M) cause Topco to dissolve and wind up its affairs; (v) cause Topco to make distributions; (vi) determine the timing, amount and other terms of any investment in Topco and to effect amendments to the Topco LLCA necessary in order to effectuate such investments and to determine on whose behalf expenses were incurred and the attribution of fees and expenses to the investment made directly or indirectly by Topco, its subsidiaries and affiliates; and (vii) make such other determinations and interpretations not provided for by the terms of the Topco LLCA, taking into account any interests and factors the Board deems appropriate.

Notwithstanding the preceding paragraph, without the prior written consent of K5, Topco shall not, and shall not permit any of its subsidiaries to, and no manager shall vote to cause any such entity to, (i) dispose of, divest, exchange or sell any material assets of Topco or any material assets, equity interests or securities of any of Topco’s subsidiaries or (ii) enter into or initiate any process in respect of a Sale Transaction, public offering, merger, combination, conversion, consolidation, amalgamation, recapitalization, reorganization, joint venture, partnership or similar transaction.

The Board may, from time to time, delegate to one or more persons (including any manager, Member or officer and including through the creation of one or more other committees) such authority and duties as the Board may deem advisable. Any such delegation may be revoked for any reason at any time by the Board.

The Topco LLCA provides that, to the maximum extent permitted under the Delaware Act and other applicable law, neither the Board nor any manager shall owe any fiduciary duties to Topco, any other manager or the Members, and any and all such fiduciary duties are thereby eliminated in all respects. Furthermore, each Member waives any right to make a claim or demand or bring a suit or action, and agrees not to make any claim or demand or bring any suit or action, against the Board or any manager that such Member may have been entitled to make or bring if such fiduciary duties were not so eliminated.

Under the Topco LLCA, the Board may from time to time appoint persons to serve as officers of Topco. Officers will have only such title, authority and duties as the Board may provide, and will hold office until such officer’s successor is appointed or until such officer dies, resigns or is removed. Officers may resign at any time by delivering written notice to the Board. Officers may be removed for any reason by the Board at any time.

Pursuant to the Topco LLCA, except as otherwise required by applicable law, the debts, liabilities, commitments and other obligations of Topco, whether arising in contract, tort or otherwise, shall be solely the debts, obligations and liabilities of Topco, and no Member shall have any personal liability whatsoever in its capacity as a Member, whether to Topco, to any of the other Members, to the creditors of Topco or to any other person, for the debts, liabilities, commitments or any other obligations of Topco or for any losses of Topco.

Except as otherwise expressly permitted by the Topco LLCA, no Member may withdraw from Topco prior to the dissolution and winding up of Topco without the prior written consent of the Board.

No Member, in its capacity as such, has the authority or power to act for or on behalf of Topco, to bind Topco, or to take any action that would or could be construed as binding on Topco, or to make any expenditures on behalf of Topco, unless such authority and power has been expressly granted to and not revoked from such Member by the Board or pursuant to the Topco LLCA.

Except as expressly and specifically provided in the Topco LLCA, the Members agree to waive any right to vote on, consent to or approve any matter or action to the greatest extent permitted by the Delaware Act, such that wherever the Delaware Act permits actions to be taken with the vote, consent or approval of Members, any group of Members or class of Members, the Topco LLCA shall be construed to have otherwise provided that such vote, consent or approval may be made by the Board without the vote, consent or approval of any Members, group of Members or class of Members. Any action, approval or consent by the Members (or a subset of Members) expressly required or permitted by the Topco LLCA may be taken (i) at a meeting called by the Board or by Members holding at least a majority of the Units entitled to approve or consent to such matter on at least 24 hours prior written notice to each Member entitled to approve or consent to such matter, which notice shall state the purpose or purposes for which such meeting is being called, or (ii) by written consent without a meeting so long as such consent is signed by Members holding at least a majority of all Units entitled to approve or consent to such matter.

Topco is permitted under the Topco LLCA to transact business with any manager, Member or officer of Topco or any affiliate thereof, provided that Topco is not permitted to enter into any agreement with any such person that is not on arms’-length terms without the prior written consent of the Board.

The Topco LLCA contains customary restrictions on Members’ use and disclosure of Confidential Information (as defined in the Topco LLCA).

Pursuant to the Topco LLCA, Topco agrees to deliver to each Member of Topco other than K5 (“Restricted Investors”) (i) all information deemed by the Board to be reasonably necessary for such Restricted Investors to comply with their respective tax reporting obligations and (ii) upon written request by any Restricted Investor, within 180 days following such statements being finalized in any fiscal year, a copy in electronic form of the audited, consolidated annual financial statements of Topco and its subsidiaries for the most recently completed fiscal year.

Under the Topco LLCA, unless otherwise determined by the Board, each Management Investor (as defined in the LLCA) is required to bring all investment or business opportunities of which such Management Investor becomes aware and which are, or may reasonably be expected to be, (x) within the scope and investment objectives related to Topco’s business or (y) otherwise competitive with Topco’s business, to Topco.

In addition, the Members expressly acknowledge and agree that (a) K5 and its affiliates and its and their respective managers, directors, officers, shareholders, members, employees, representatives and agents (the “Specified Persons”) are

permitted (i) to have, develop and engage in, and may presently or in the future have, develop and engage in, investments, transactions, business ventures, contractual, strategic or other business relationships, prospective economic advantages or other opportunities (the “Business Opportunities”) in businesses that are and may be competitive or complementary with or to Topco and its subsidiaries, for their own account or for the account of any person other than Topco and its subsidiaries or any other Member, and (ii) to direct any such Business Opportunities to any other person, in each case, regardless of whether such Business Opportunities are presented to a Specified Person in such Specified Person’s capacity as a manager or otherwise, (b) none of the Specified Persons will be prohibited by virtue of their investments in Topco and its subsidiaries or their service as a manager or service on the Board or otherwise from pursuing and engaging in any such activities or consummating transactions related thereto, (c) none of the Specified Persons will be obligated to inform or present Topco and its subsidiaries or the Board or any other Member of or with any such Business Opportunity and (d) neither Topco and its subsidiaries nor any other Member will have or acquire or be entitled to any interest or expectancy or participation in any Business Opportunity as a result of the involvement therein of any of the Specified Persons.

The Topco LLCA also provides that, to the maximum extent permitted by the Delaware Act and other applicable law, K5 shall not owe any fiduciary duties to any other Members, and any and all such fiduciary duties are thereby eliminated. Furthermore, each Member thereby waives and agrees not to make any claim or demand or bring any suit or action against K5 (or any of its affiliates, employees, representatives or agents), the Board or any manager (or any of their respective affiliates, employees, representatives or agents) in respect thereof.

Except as set forth in the Topco LLCA, and subject to the terms of any Equity Plan (defined below), distributions shall be made, subject to any offsets permitted by the terms of the Topco LLCA, to the holders of Class A Units and Class B Units ratably among such holders based on the number of Class A Units and Class B Units held by each such holder immediately prior to each such distribution.

As noted above, pursuant to the Topco LLCA, the timing and amount of any distributions by Topco are solely within the authority and discretion of the Board.

Under the terms of the Topco LLCA, no Restricted Investor may, without the prior written consent of K5 and the Board, transfer its Membership Interest, LLC Interest (in each case, as defined in the Topco LLCA) or any of its Units. Notwithstanding the foregoing, Management Investors may transfer Units to certain permitted transferees in certain circumstances, as more fully described in the Topco LLCA.

Furthermore, each Restricted Investor that is not a natural person agrees under the Topco LLCA to (i) take such action as necessary to prohibit and prevent the direct or indirect transfer of all or any portion of the direct or indirect equity or beneficial interest in such Restricted Investor or any person holding an interest in such Restricted Investor and (ii) not seek to avoid the foregoing transfer restrictions by issuing, or permitting the issuance of, any direct or indirect equity or beneficial interest in such Member in a manner that would fail to comply with the Topco LLCA if such Member had transferred Units directly.

The Topco LLCA provides that if K5 desires to sell or otherwise dispose of the Units held by K5 at any time (other than pursuant to an Exempt Transfer (as defined in the Topco LLCA)), and the effect of such sale or other disposal, if completed, would be that K5 is no longer, in the aggregate, the beneficial owner, directly or indirectly through one or more intermediaries, of Units representing more than 50% of the Total Equity Value (as defined in the Topco LLCA), then K5 shall provide each Restricted Investor with reasonable prior written notice thereof (which notice shall include the estimated per Unit consideration, the date by which such Restricted Investor must elect to participate and other material terms of such sale or other disposal that K5 deems relevant) and the opportunity (to be exercised by such Restricted Investor in writing delivered to K5 prior to such date) to participate in and sell or otherwise dispose of such Restricted Investor’s pro rata share of the Units being sold or disposed of by K5 (based on the number of Units held by such Restricted Investor relative to the aggregate number of Units held by all Members) for the same amount and kind of consideration received by K5.

If requested by K5 in connection with such sale or other disposal, such participating Restricted Investor agrees pursuant to the Topco LLCA to sign and deliver any customary agreements and other documentation (provided that any indemnity obligations shall be on a pro rata basis and limited in amount to no more than the sale or other disposal proceeds actually received by such Restricted Investor).

Under the Topco LLCA, a “Sale Transaction” means, unless otherwise determined by the Board, (i) a transaction or series of transactions with any unaffiliated third party the result of which is that (a) K5 is no longer, in the aggregate, the beneficial owner of Units representing more than 50% of the Total Equity Value, (b) Topco is no longer, in the aggregate, the beneficial owner of equity interests representing more than 50% of the aggregate equity value of MariaDB USA Inc., or (c) the K1 Managers no longer hold a majority of the total votes of the Board or (ii) the sale, in one transaction or a series of transactions, of all or substantially all of the assets of Topco and its subsidiaries, taken as a whole, to an unaffiliated party.

If either (i) the Board and K5 or (ii) K5 (independently of the Board) approve a Sale Transaction (an “Approved Sale”), each Member, in its capacity as such, agrees to raise no objections against, and not to otherwise hinder, impede, delay or take any action that could cause any adverse effect on, such Approved Sale.

If the Approved Sale is structured as a (x) merger or consolidation and the waiver by the Members pursuant to the Topco LLCA of any right to vote on, consent to or otherwise approve any actions that under the Delaware Act such Members would have been entitled to vote on, consent to or otherwise approve in the absence of such waiver, is or becomes invalid or unenforceable under the Delaware Act or is determined by a court of competent jurisdiction to be invalid or unenforceable, then each Member shall vote for, consent to and, to the extent applicable under the laws governing such transaction, waive any dissenters rights, appraisal rights or similar rights in connection with such merger or consolidation or (y) sale of Units, each Member agrees to transfer, and shall transfer, all (or such lesser portion reflecting such person’s proportionate interest in the aggregate portion of the Total Equity Value being sold in such Approved Sale) of such Member’s Units on the terms of the Sale Transaction approved by the Board and K5 acting together or K5 acting alone, as the case may be. In addition, each Member agrees to take all necessary or customary actions, and the receipt of any proceeds of such Approved Sale shall be conditioned on the taking of such actions, in connection with the consummation of the Approved Sale (whether in such person’s capacity as a Member, manager, officer or otherwise) as reasonably requested by the Board and K5 acting together or K5 acting alone, as the case may be (including signing and delivering any and all agreements, instruments, consents, waivers and other documents in substantially the same forms signed by K5 and any other customary agreements and documentation, including any applicable purchase agreement and, solely with respect to Management Investors, attending presentations, cooperating in facilitating the sale process and providing information reasonably requested by potential acquirers, in each case, on terms which shall be determined by the Board. Notwithstanding the foregoing, no Member shall be required to make any representations and warranties other than customary “fundamental” representations and warranties relating to such Member’s status as a holder and seller of Units, including in respect of such Member’s unencumbered title to its Units, its power, authority and legal right to transfer its Units, and the enforceability against such Member of agreements to which such Member is a signatory.

The foregoing obligations of the Members under the Topco LLCA with respect to an Approved Sale are subject to the satisfaction of the following conditions: (i) the consideration payable on consummation of such Approved Sale to all Members shall be allocated among the Members based on the pro rata share represented by the Units sold by such Member pursuant to such Approved Sale (as determined by the Board, treating the Units sold pursuant to the Approved Sale as the only Units outstanding for the purposes of determining each such Unit’s pro rata share) and (ii) on the consummation of the Approved Sale, all of the Members holding a particular class of Unit shall receive (or shall have the option to receive) the same form of consideration for such class of Unit (provided that the condition that each Member is provided with the same option to receive the same form of consideration shall be deemed satisfied even if (x) any Management Investor receives additional consideration in the form of salary, bonus or other management consideration for entering into employment or similar arrangements in favor of an acquiror, (y) any Management Investor elects to receive securities of the acquiror or any of its affiliates or (z) certain Members (other than the Management Investors) elect to receive securities of the acquiror or any of its affiliates, so long as such election is available to all Members holding the same class of Units and so long as each holder of the same class of Units receives the same amount of value, whether in cash or such securities, as of the closing of such Approved Sale with respect to such holder’s Units of such class (provided further that, in the event that any securities are part of the consideration payable to the Members, if a Member is not an “accredited investor” (as such term is defined under the Securities Act) or the receipt of such securities might have an adverse effect on such Approved Sale, then the Board may cause such Member to receive, and each such Member hereby agrees to accept, in lieu of such securities, cash consideration equal to the fair market value of such securities as of the closing of such Approved Sale)).

In connection with an Approved Sale, the Members shall be obligated to join (severally but not jointly, and on a pro rata basis) in any indemnification obligation the Board and K5 acting together or K5 acting alone, as the case may be, have agreed to be bound by in connection with such Approved Sale (including any such obligations that relate specifically to a particular Member, such as indemnification with respect to representations and warranties given by a Member regarding such Member’s title to and ownership of Units), provided that any escrow or holdback of proceeds of any such transaction shall be withheld on a pro rata basis among all Members, and provided further that (i) in respect of representations that are specific to a Member (e.g., ownership of Units), no Member will be required to make such Member-specific representations about other Members or indemnify a buyer in respect thereof and (ii) no Member shall be obligated in connection with an Approved Sale to agree to indemnify any party with respect to an amount in excess of the cash proceeds actually received by such Member in connection with such Approved Sale. Each Member shall also enter into any indemnification or contribution or other agreement reasonably requested by the Board and K5 acting together or K5 acting alone, as the case may be, to ensure compliance with the foregoing obligations. Each Member also agrees to pay its share, determined on a pro rata basis, of the expenses incurred by K5 and its affiliates pursuant to an Approved Sale to the extent such expenses are incurred for the benefit of all Members. Expenses incurred by any Member on such Member’s own behalf (including the fees and disbursements of counsel, advisors and other persons retained by such Member in connection with the Approved Sale) will not be considered costs incurred for the benefit of all Members and, to the extent not paid by Topco, will be the responsibility of such Member.

The Topco LLCA provides that it shall in no manner be construed to grant to any Member any dissenters rights or appraisal rights or give any Member any right to vote in any transaction structured as a merger or consolidation. Furthermore, each Member expressly grants to the Board and K5 acting together or K5 acting alone, as the case may be, the sole right to approve or consent to a Sale Transaction (or other merger or consolidation involving Topco) without approval or consent of the Members. The Topco LLCA also provides that K5 shall, in its sole discretion, decide whether or not to pursue, consummate, postpone or abandon any Approved Sale and the terms thereof, and neither K5 nor any of its affiliates shall have any liability to any other Member arising from, relating to or in connection with the pursuit, consummation, postponement, abandonment or terms of any such Approved Sale.

Except as provided in the Topco LLCA, and unless otherwise determined by the Board, the transferor and transferee of any Units shall be jointly and severally obligated to pay all reasonable expenses (including attorneys’ fees and expenses) incurred by Topco or any of its affiliates in connection with any transfer or proposed transfer, whether or not such proposed transfer is consummated.

The Topco LLCA provides Topco with the right to, at any time following the termination of a Management Investor’s employment or engagement for any reason, repurchase all or any portion of the Units issued to such Management Investor. This right is subject to the terms of any Equity Plan or other plan or agreement governing such Units, as well as any applicable restrictions and limitations contained in the Delaware Act, the Delaware General Corporation Law, and such other applicable governing law, and in Topco’s and its subsidiaries’ debt and equity financing agreements, in each case, as of the time of any repurchase.

Topco may exercise its repurchase right by written notice to the holders of such Units of the aggregate number of Units it is repurchasing, the aggregate purchase price therefor, the contemplated date of such repurchase and any other material terms of such repurchase. Under the terms of the Topco LLCA, the holders of such Units will be required to sign and deliver to Topco documentation effectuating the repurchase, as reasonably requested by, and in a form reasonably acceptable to, Topco.

The purchase price for any Units repurchased from Management Investors shall be the fair market value of such Units as of the date of the repurchase notice, as conclusively determined by the Board, and subject to the provisos set forth in the Topco LLCA. Topco may pay the purchase price for the Units by check or wire transfer of immediately available funds or by issuing (or causing a subsidiary to issue) a promissory note bearing simple interest (payable at maturity) at a rate equal to the prime rate, which note shall mature and be payable on the earlier of the consummation of a Sale Transaction and the date that is the third anniversary of the closing of such repurchase (or by any combination of the foregoing).

Topco may assign all or any portion of its rights to repurchase Units under the Topco LLCA to K5 or any person consented to in writing by K5 and may effectuate the repurchase of Units through any of its subsidiaries.

The Topco LLCA contemplates that the Board may, at a later date, adopt an incentive plan in respect of Units (the “Equity Plan”).

Topco shall continue in existence until the Board determines that it shall be dissolved and its affairs be wound up or it is dissolved pursuant to Section 18-802 of the Delaware Act. Neither the admission of a new Member nor the death, retirement, resignation, expulsion, bankruptcy or dissolution of a Member, or the occurrence of any other event that terminates the continued membership of a Member in Topco, shall cause a dissolution of Topco.

Pursuant to the Topco LLCA, on the dissolution of Topco, the Board or its designee shall act as liquidator or may appoint one or more representatives, Members or other persons as liquidators. The liquidators shall proceed diligently to wind up the affairs of Topco and make final distributions as provided under the Topco LLCA and in the Delaware Act. The costs of liquidation shall be borne as Topco’s expense. Until final distribution, the liquidators shall continue to operate Topco’s properties with all of the power and authority of the Board.

The Board may amend the Topco LLCA without the consent of any Member as provided thereunder, and otherwise with the prior written consent of K5, and such amendment shall be binding on all Members as if such Members had expressly consented thereto. Notwithstanding the foregoing, if any amendment would materially and adversely affect (a) the economic rights of the Class B Units in a disproportionate manner to the economic rights of the Class A Units or (b) the rights of the Restricted Investors with respect to their tag-along rights, rights on an Approved Sale, repurchase rights, or rights in respect of any amendments to the Topco LLCA, then such amendment requires the prior written consent of the Restricted Investors holding a majority of such Class B Units (such consent not to be unreasonably withheld, conditioned or delayed).

Pursuant to the Topco LLCA, to the extent that K1 Investment Management, K1 Group (in each case, as defined in the Topco LLCA), K5 or any of their respective affiliates, on behalf of Topco, incurs administrative costs and expenses in respect of the formation, maintenance and operation of Topco and its subsidiaries, including annual filing fees and tax preparation fees, then (x) Topco shall reimburse such persons or a designee thereof for such reasonable costs and expenses prior to making any distributions pursuant to the Topco LLCA or (y) the net proceeds payable to the Members in a Sale Transaction shall be reduced by such amount and paid to such persons or such designee thereof.

The law of the State of Delaware governs all claims, controversies or matters related to or arising from the Topco LLCA, any questions concerning the construction, interpretation, validity and enforceability of such agreement, and the performance of the obligations imposed by such agreement, in each case, without giving effect to any choice of law or conflict of law rules or provisions (whether of the State of Delaware or any other jurisdiction) that would cause the application of the law of any jurisdiction other than the State of Delaware.

Except with respect to claims for specific performance or injunctive or other equitable relief, and except for certain final judgments, all actions, proceedings, disputes, matters or claims related to or arising from the Topco LLCA are to be heard and determined through the binding arbitration mechanisms described further in Exhibit A to the Topco LLCA.

Re: Recommended Cash Offer for MariaDB plc (“MariaDB”) by Meridian Bidco LLC (“Bidco”),

(i) an Affiliate of K1 Investment management LLC (“K1”) as manager of K5 Private Investors L.P. (“K5”)

and (ii) a wholly owned subsidiary of Meridian Topco LLC (“Topco”)

Dear Sirs,

We refer to the recommended cash offer for MariaDB by Bidco announced on April 24, 2024 (the “Offer”). Under the terms of the Offer, each MariaDB Shareholder is entitled to receive $0.55 in cash for each MariaDB Share. As an alternative, Eligible MariaDB Shareholders may elect to receive, in lieu of the cash to which they are otherwise entitled, one unlisted, unregistered non-voting Class B unit of Topco (each, a “Topco Rollover Unit”) for each MariaDB Share (the “Unlisted Unit Alternative”).

Pursuant to the requirements of Rule 24.11 of the Irish Takeover Rules (the “Takeover Rules”), you have requested our opinion as to the estimated value of the Topco Rollover Units and, accordingly, the Unlisted Unit Alternative as of the Latest Practicable Date (the “Estimate of Value”).

The Topco Rollover Units are unlisted and therefore do not have a public valuation. It is not proposed that the Topco Rollover Units will be admitted to trading on any recognized stock exchange or other market after the Unconditional Date, nor is it proposed that any alternative trading facilities will be made available.

The rights of a holder of Topco Rollover Units are described in Appendix 2 and Appendix 4 of the offer document dated May 24, 2024 in relation to the Offer (the “Offer Document”) and risk factors relating to the holding of Topco Rollover Units are set out in Appendix 9 of the Offer Document.

Capitalized terms used in this letter will, unless otherwise stated, have the same meanings given to them in the Offer Document of which this letter forms part.

This Estimate of Value has been provided to the directors of Bidco solely for the purposes of Rule 24.11 of the Irish Takeover Rules and may not be used or relied upon by Bidco or any other person for any other purpose whatsoever. In particular, the Estimate of Value is not a valuation that has been prepared as a result of the requirements of, or in accordance with, nor has any regard been had to, the terms of any applicable law or regulations in any jurisdiction other than Ireland. It is not addressed to, and may not be relied upon by, any other person (including any creditor, employee or shareholder of MariaDB) for any purpose whatsoever and Lazard Frères & Co. LLC (“Lazard Frères”), on behalf of itself and its affiliates, including Lazard & Co., Limited, expressly disclaims any duty, liability or responsibility (whether direct or indirect, whether in contract, in tort, under statute or otherwise) of Lazard Frères or any of its affiliates to any third party (including any creditor, employee or shareholder of MariaDB) with respect to the contents of this letter.

In providing this Estimate of Value, Lazard Frères consents to the inclusion of this Estimate of Value in the Offer Document on the basis that no duties or responsibilities are accepted by Lazard Frères or any of its affiliates to any third party, individually or collectively, with respect to this Estimate of Value. This letter sets out our Estimate of Value, which is an estimate of the fair market value of a Topco Rollover Unit as of the Latest Practicable Date, assuming such Topco Rollover Unit had been in issue as of the Latest Practicable Date and there was as of the Latest Practicable Date a willing buyer and seller with equal bargaining power, neither being under any compulsion to buy or sell, dealing on an arm’s length basis, each having equal knowledge of all relevant facts. We have assumed for this purpose that, as of the Latest Practicable Date, the Offer had become Effective, that MariaDB is a wholly owned

subsidiary of Bidco, that the Topco Rollover Units had been validly issued and the Offer would be implemented on the terms described in the Offer Document, without any modification of any material terms or conditions. We have also assumed that obtaining the necessary governmental, regulatory or third party approvals and consents for the Offer would not have an adverse effect on MariaDB, Bidco, Topco or the Offer and that, following the Offer becoming Effective, Topco would, as contemplated in the Offer Document, both (i) cancel the RPV Note and (ii) provide additional equity of at least $23 million to MariaDB.

This Estimate of Value does not represent the value that a holder of Topco Rollover Units may realise on any future sale of Topco Rollover Units; such a value may be higher or lower than the range set out in this letter.

In arriving at the Estimate of Value, we have, among other things:

We have relied on, and assumed, without independent verification (nor have we assumed responsibility or liability for independently verifying), the accuracy and completeness of the information reviewed by us for the purposes of this Estimate of Value and this Estimate of Value is conditional upon such accuracy and completeness. We did not conduct any independent valuation or appraisal of any of the assets or liabilities (contingent or otherwise) of MariaDB, Bidco or Topco or concerning the solvency of MariaDB, Bidco or Topco, and we were not furnished with any such valuation or appraisal. We were not provided with access to management of MariaDB in connection with preparation of our Estimate of Value and we did not receive financial forecasts prepared by management of MariaDB other than limited financial forecasts prepared by MariaDB in December 2023 which covered only their expectations at that time with respect to 2024. Accordingly, for purposes of our Estimate of Value, at your direction, we have utilized only the Forecasts (and not any other forecast scenario provided by K1). With respect to the Forecasts, you have informed us, and we have assumed, that they have been reasonably and properly prepared by K1 on bases reflecting K1’s best currently available estimates and judgments of the future financial performance of Topco. In addition, we have assumed that the Forecasts would be realized in the amounts and at the times contemplated thereby. We assume no responsibility for and express no view as to the Forecasts or the assumptions on which they are based and this letter does not constitute a report under Rule 28.1(a) of the Takeover Rules in relation to the Forecasts. We have also assumed the accuracy and fair presentation of, and relied upon, MariaDB’s audited financial statements and the reports of the auditors thereon and MariaDB’s unaudited interim financial statements.

Our Estimate of Value is necessarily based on economic, monetary, market, general business, financial and other conditions prevailing on the Latest Practicable Date and the condition and prospects, financial and otherwise, of Topco as they were reflected in the information provided to us. Any changes therein may affect this Estimate of Value and we disclaim any undertaking or obligation to advise any person of any such change that may come to our attention or to update or revise this Estimate of Value at any time. We further note that the current volatility and disruption in the credit and financial markets as of the Latest Practicable Date may or may not have an effect on MariaDB, K1, Bidco or Topco and we express no opinion as to the effects of such volatility or such disruption on MariaDB, K1, Bidco or Topco.

The taxation position of individual MariaDB Shareholders will vary and so we express no opinion as to any tax or other consequences that might result from the Offer or the holding of Topco Rollover Units, including the effects of any taxation exemptions, allowances or reliefs available for the purposes of income, capital gains, inheritance or any other applicable tax, duty or levy, notwithstanding that these may be significant in the case of some MariaDB Shareholders.

We express no opinion as to any legal, tax, regulatory or accounting matters, as to which we understand that K1 and Bidco have obtained such advice as they deem necessary from qualified professionals.

In analyzing the range of value of the Topco Rollover Units for purposes of this Estimate of Value, no account has been taken of any potential transaction costs that a holder of Topco Rollover Units may incur, including any associated dealing costs, or any potential costs that may be associated with a sale of Topco to a third party or a liquidation of Topco and which might be expected to reduce any return to a holder of a Topco Rollover Unit upon the occurrence of such an event.

In addition, no account has been taken of any minority shareholder issues arising from the existence of a controlling shareholder in Topco, or of the fact that K5, as controlling member of Topco, has power to appoint all of the members of the board of Topco, who have the exclusive authority and power to manage the business and affairs of Topco, and we have not made any adjustment for such factors.

In performing this analysis, we have relied upon certain assumptions provided by K1 with respect to general business, economic and market conditions, many of which are beyond the control of Topco. This Estimate of Value may differ substantially from estimates available from other sources. In addition, our view would be expected to fluctuate with changes in prevailing market and industry conditions, the financial performance and prospects of Topco and other factors after the date of this letter which generally influence the valuation of companies and securities.

The valuation of non-publicly traded securities is inherently imprecise and is subject to certain uncertainties and contingencies, all of which are difficult to predict and are beyond our control. As it relates to the Topco Rollover Units, the reasons for this inherent uncertainty include, but are not limited to, the following factors, as well as the risk factors relating to the holding of Topco Rollover Units set out in Appendix 9 of the Offer Document:

1. The Topco Rollover Units will be:

a. unquoted and will not be listed or admitted to trading on any exchange or market for the trading of securities, and will therefore be illiquid. In addition, the Topco Rollover Units will not be registered under US securities laws;

b. non-transferable, other than with the prior written consent of K5 (and then only in K5's sole and absolute discretion). The future monetisation of the Topco Rollover Units therefore remains entirely in the discretion of K5, subject to a customary “tag-along” right for Topco Rollover Units as described in Appendix 2 and Appendix 4 of the Offer Document;

c. of uncertain value at all times and there can be no assurance that they will be capable of being sold in the future or that they will be capable of being sold at the value per the Estimate of Value;

2. Upon the Unconditional Date, Topco will be solely controlled by K5, who will exercise all decision-making powers relating to Topco and its Subsidiaries (including Bidco and all members of the MariaDB Group) and the businesses thereof. Holders of the Topco Rollover Units, which will not carry any voting rights (other than those non-waivable voting rights, if any, required pursuant to applicable Delaware law) or rights to appoint (or vote for the appointment of) directors, officers or other control persons of Topco, will therefore have no influence over decisions made by Topco in relation to its investment in MariaDB or in any other business;

3. Individual holders of Topco Rollover Units will have limited control (if any) over the date(s) on and value(s) at which they may be able to realise their investment in the Topco Group;

4. The Topco Rollover Units will be subject to a customary “drag-along” right. As a result, given its sole control over Topco, K5 will have sole and absolute discretion to “drag” the holders of Topco Rollover Units, at any time, into a future sale or change of control transaction involving Topco or any of its Subsidiaries (including MariaDB) and require such holders to sell or transfer their Topco Rollover Units, and K5 will therefore control the future monetization of the Topco Rollover Units;

5. K5 will control the timing of distributions, dividends and payments of capital proceeds (in each case, if any) to the holders of Topco Rollover Units and will also control the capital structure of Topco as a whole, with the ability to take decisions in its sole discretion as to, among other things, the incurrence of debt financing and the structure and terms thereof, all of which may materially affect the Topco Rollover Units. There is no guarantee that Topco will make any distributions, dividends or payments of capital proceeds at any time with respect to the Topco Rollover Units (however, Topco Rollover Units will rank pari passu with Class A Topco Units in respect of any such distributions, dividends or payments of capital proceeds that are made);

6. None of K1, Topco or Bidco are contractually bound to (i) cancel the RPV Note or (ii) provide any additional liquidity to MariaDB;

7. Topco Rollover Units will carry no pre-emption rights and any participation by the holders of Topco Rollover Units in future issues of securities by the Topco Group will be at the discretion of K5 and also be subject to other important exceptions and risk which may result in them suffering significant dilution;

8. The holders of Topco Rollover Units will enjoy only limited minority protections and other rights as described in Appendix 2 and Appendix 4 of the Offer Document;

9. K5 may freely dispose of some or all of its Class A Topco Units, meaning that the holders of Topco Rollover Units may find themselves owning units in Topco alongside different owners. The Topco Rollover Units will benefit from a “tag-along” right (as described in Appendix 2 and Appendix 4 of the Offer Document), but K5 will be able to dispose of some or all of its Class A Topco Units without triggering this tag-along right;

10. Individual holders of Topco Rollover Units will have very limited control (if any) over the date(s) on and value(s) at which they may be able to realize their investment in the Topco Group; the value of the Topco Rollover Units will at all times be uncertain and there can be no assurance that any Topco Rollover Units will be capable of being sold in the future or that they will be capable of being sold at the value estimated in this letter;

11. Holders of Topco Rollover Units will have no opportunity to convert their Topco Rollover Units into Class A Topco Units;

12. The MariaDB Shares are currently admitted to trading on NYSE and MariaDB Shareholders are afforded certain standards and protections, including in respect of disclosure. As a result. MariaDB Shareholders who receive Topco Rollover Units (being unlisted, unregistered securities in a private company) will not be afforded protections commensurate with those that they currently benefit from as shareholders in MariaDB, including because Topco intends to rely on an exemption from registration under US securities laws and will therefore not be registering the Topco Rollover Units with the SEC. Except for certain limited information to be provided to holders of the Topco Rollover Units as described in Appendix 2 and Appendix 4 of the Offer Document, the Topco LLCA will not provide holders of Topco Rollover Units with information rights;

13. There can be no certainty or guarantee as to the performance of the Topco Group or the MariaDB Group following the Effective Date, and past performance cannot be relied upon as an indication of future performance or growth; while K1 has stated in the Offer Document that it intends to focus on key operational initiatives to position MariaDB for sustainable long-term growth, these operational initiatives carry high levels of execution risk;

14. There is no certainty as to the number of MariaDB Shareholders that will accept the Offer and therefore Topco may hold less than all of the MariaDB Shares following the Initial Closing Date and which, therefore, could impact the value of Topco’s assets; and

15. MariaDB Shareholders will have no certainty as to the amount of Topco Rollover Units they would receive because:

a. the maximum number of Topco Rollover Units available to MariaDB Shareholders under the Unlisted Unit Alternative will be limited to the Rollover Threshold; and

b. to the extent that elections for the Unlisted Unit Alternative cannot be satisfied in full, the number of Topco Rollover Units to be issued to each MariaDB Shareholder who has elected for the Unlisted Unit Alternative will be reduced on a pro rata basis, and the consideration for each MariaDB Share that is not exchanged for Topco Rollover Units will be paid in cash in accordance with the terms of the Cash Offer.

Any assessment of the value of the Topco Rollover Units to an individual shareholder should take into account an individual shareholder's assessment of an appropriate discount to reflect the illiquidity of the Topco Rollover Units and the other factors described in this section. We have not made any adjustment in respect of any illiquidity discount or to address any of the other factors described in this section.

In arriving at the Estimate of Value:

(a) we have primarily relied on a valuation analysis based on financially comparable companies public trading analysis and discounted cash flow analysis; and

(b) we have not made any adjustment for the illiquidity or non-transferability of the Topco Rollover Units, or the governance arrangements in relation to Topco, either in relation to the discount rate used in the discounted cash flow analysis, or in relation to the Estimate of Value itself, or made any adjustment for any of the other factors described in this section.

We have produced the Estimate of Value using this methodology and taken into account the information, factors, assumptions and limitations set out in this letter.

In particular, when calculating the Estimate of Value, we applied the financially comparable companies public trading analysis and discounted cash flow analysis to the Forecasts. MariaDB Shareholders should note that the Estimate of Value is highly sensitive to a number of assumptions, including amongst others the future financial performance and financial position of Topco.

Any assessment that an Eligible MariaDB Shareholder may wish to make as to the appropriate discount, if any, to take into account the illiquidity or non-transferability of the Topco Rollover Units, the governance arrangements in relation to Topco, or any of the other factors described in this section will depend on, among other things, the type of holder and their individual circumstances and we therefore make no estimate of, and express no opinion as to, the materiality or amount of any such discount.

On the basis of and subject to the matters described in sections headed “Information” and “Methodology”, if the Topco Rollover Units had been in issue as of the Latest Practicable Date, the Estimate of Value (being the estimated value of each Topco Rollover Unit) would be in the range of $0.40 to $0.65 per Topco Rollover Unit.

Lazard Frères and its affiliate, Lazard & Co., Limited (together, “Lazard”) are acting exclusively as financial adviser to K1 and Bidco and no one else in connection with the Offer and will not be responsible to anyone other than K1 and Bidco for providing the protections afforded to clients of Lazard nor for providing advice in relation to this letter or any other matters referred to in this letter or any other document or announcement issued or to be issued in connection with the Offer. Neither Lazard nor any of its affiliates owes or accepts any duty, liability or responsibility whatsoever (whether direct or indirect, whether in contract, in tort, under statute or otherwise) to any person who is not a client of Lazard in connection with this letter or any other document or announcement issued or to be issued in connection with the Offer, any statement contained herein or therein, or otherwise.

Lazard will receive certain fees from K1 and Bidco for our services, a portion of which are payable upon delivery of this letter and the majority of which are contingent upon the Offer becoming Effective.

Eligible MariaDB Shareholders who may be considering a continuing investment in the future of MariaDB through the Topco Rollover Units are urged to read carefully all the information relating to the Topco Rollover Units contained in the Offer Document and the Offering Memorandum, and to also read in full the Topco LLCA.

This letter is not addressed to, or provided on behalf of, nor shall it confer any rights or remedies upon, any shareholder, employee or creditor of MariaDB or any other person whatsoever. In providing this Estimate of Value, we express no opinion or recommendation to any person as to whether they should accept the Offer or whether they should make an election for the Unlisted Unit Alternative. MariaDB Shareholders should seek their own independent financial advice.

This Estimate of Value does not address the relative merits of the Offer as compared to other transactions or business strategies that might be available to K1, Bidco, Topco or MariaDB, the merits of the underlying decision by K1, Bidco, Topco and MariaDB to engage in the Offer, or the election which Eligible MariaDB Shareholders may make

in respect of the Unlisted Unit Alternative. We express no opinion with respect to the future trading prices of securities of MariaDB or any of its affiliates or the future value at which Topco Rollover Units may be sold. In addition, we express no view or opinion as to the fairness of the amount or nature of, or any other aspects relating to, the compensation to any officers, directors or employees of any parties involved in the Offer, or class of such persons, relative to the consideration payable to MariaDB Shareholders or otherwise.

We express no opinion as to the fairness of the financial terms of the Offer or the Unlisted Unit Alternative, or as to any terms or other aspects of the Offer, including, without limitation, the form or structure of the Offer or any agreements or arrangements entered into in connection with, or contemplated by, the Offer.

This letter may be reproduced in full in the Offer Document on the basis that no duties or responsibilities are accepted by Lazard to any person, individually or collectively, but this letter may not otherwise be published or reproduced publicly in any manner without our prior written approval.

This letter and all matters contained in this letter (in addition to any non-contractual matters arising out of or in connection with this letter) shall be governed by and construed in accordance with Irish law, and the courts of the Republic of Ireland are to have exclusive jurisdiction for the purpose of determining any matter arising out of or in any way relating to this letter.

Yours faithfully,

MariaDB Shareholders who validly tender their MariaDB Shares in the Offer and elect to receive the Unlisted Unit Alternative may, in accordance with the terms of this Offer Document, receive Topco Rollover Units following consummation of the Offer. MariaDB Shareholders should note that no application for quotation of the Topco Rollover Units has been or will be made to any stock exchange or market.

As MariaDB is an Irish public limited company, the rights of MariaDB Shareholders are currently governed by the Irish Companies Act 2014, the constitution of MariaDB and other laws affecting Irish companies. As Topco is a Delaware limited liability company, the rights of the MariaDB Shareholders who receive Topco Rollover Units pursuant to the Offer will be governed by the applicable laws of the State of Delaware, including the Delaware Limited Liability Company Act, and by the Topco LLCA. The following summary compares the material differences between the rights of MariaDB Shareholders and the rights of the holders of Topco Rollover Units.

The section does not include a complete description of all differences between the rights of MariaDB Shareholders and the holders of Topco Rollover Units, nor does it include a complete description of the specific rights referred to below. Furthermore, the description of some of the differences in rights in this section is not intended to indicate, and does not indicate, that other differences, each of which may be of equal or greater importance than the differences set forth herein, do not exist. All MariaDB Shareholders are urged to read carefully and compare the relevant provisions of the Irish Companies Act 2014 and the Delaware Limited Liability Company Act, as well as each company’s governing documents; this summary is qualified in its entirety by reference to the full text of the constitution of MariaDB as adopted on 16 December 2022 (the “MariaDB Constitution”), attached as Exhibit 3.1 to the MariaDB Annual Report, and the Topco LLCA.

The information incorporated by reference is considered to be part of this Offer Document, and information that MariaDB files later with the SEC will automatically update and supersede information included or previously incorporated by reference into this Offer Document from the date MariaDB files the document containing such information. Any statement so modified or superseded shall not be deemed, except as so modified or superseded, to constitute a part of this Offer Document. Except to the extent furnished and not filed with the SEC pursuant to Items 2.02 or 7.01 of Form 8-K or as otherwise permitted by the SEC rules, we incorporate by reference the documents listed below and any future filings MariaDB will make with the SEC under Sections 13(a), 13(c), 14 or 15(d) of the Exchange Act from and including the date hereof to the date that is the later of the date of the Offer is completed or the Offer is terminated, and such documents shall be deemed to be incorporated by reference into this Offer Document and to be a part of this Offer Document from the respective dates of filing thereof.
