INDUSTRY AND MARKET DATA

Within this prospectus, we reference information and statistics regarding the industry in which we operate. We have obtained this information and statistics from various independent third-party sources,

 

i

CONFIDENTIAL TREATMENT REQUESTED

PURSUANT TO 17 C.F.R. SECTION 200.83

independent industry publications, reports by market research firms, and other independent sources. Some data and other information contained in this prospectus are also based on management’s estimates and calculations, which are derived from our review and interpretation of internal surveys and independent sources, as well as third-party reports commissioned by us. The information is as of its original publication dates (and not as of the date of this prospectus). Data regarding the industries in which we compete and our market position and market share within these industries are inherently imprecise and are subject to significant business, economic, and competitive uncertainties beyond our control, but we believe they generally indicate size, position, and market share within these industries. While we believe such information is reliable, we have not independently verified any third-party information, and our internal company research, data, and estimates have not been verified by any independent source.

In addition, assumptions and estimates of our and our industry’s future performance are subject to a high degree of uncertainty and risk due to a variety of factors, including those described in “Risk Factors.” These and other factors could cause our future performance to differ materially from our assumptions and estimates. See “Forward-looking Statements.” As a result, you should be aware that market, ranking, and other similar industry data included in this prospectus, and estimates and beliefs based on that data may not be reliable. None of us, the selling stockholders, or the underwriters can guarantee the accuracy or completeness of any such information contained in this prospectus.

NON-GAAP FINANCIAL MEASURES

This prospectus contains “non-GAAP financial measures” that are financial measures that either exclude or include amounts that are not excluded or included in the most directly comparable measures calculated and presented in accordance with GAAP. Specifically, we make use of the non-GAAP financial measures “Adjusted EBITDA,” “Adjusted EBITDA margin,” “non-GAAP net income/(loss),” and “non- GAAP net income/(loss) per share.” Adjusted EBITDA, Adjusted EBITDA margin, non-GAAP net income/ (loss), and non-GAAP net income/(loss) per share have been presented in this prospectus as supplemental measures of financial performance that are not required by, or presented in accordance with, GAAP. We believe they assist investors and analysts in comparing our operating performance across reporting periods on a consistent basis by excluding items that we do not believe are indicative of our core operating performance. Management believes Adjusted EBITDA, Adjusted EBITDA margin, non-GAAP net income/(loss), and non-GAAP income/(loss) per share are useful to investors in highlighting trends in our operating performance, while other measures can differ significantly depending on long-term strategic decisions regarding capital structure, the tax jurisdictions in which we operate, and capital investments. Management uses Adjusted EBITDA, Adjusted EBITDA margin, non-GAAP net income/(loss), and non-GAAP net income/(loss) per share to supplement GAAP measures of performance in the evaluation of the effectiveness of our business strategies, to make budgeting decisions, to establish discretionary annual incentive compensation, and to compare our performance against that of other peer companies using similar measures. Management supplements GAAP results with non-GAAP financial measures to provide a more complete understanding of the factors and trends affecting the business than GAAP results alone provide.

Adjusted EBITDA, Adjusted EBITDA margin, non-GAAP net income/(loss), and non-GAAP net income/(loss) per share are not recognized terms under GAAP and should not be considered as an alternative to net income (loss) or net income (loss) margin as measures of financial performance or cash provided by operating activities as a measure of liquidity, or any other performance measure derived in accordance with

 

iii

CONFIDENTIAL TREATMENT REQUESTED

PURSUANT TO 17 C.F.R. SECTION 200.83

GAAP. Additionally, these measures are not intended to be a measure of free cash flow available for management’s discretionary use, as they do not consider certain cash requirements such as interest payments, tax payments, and debt service requirements. The presentations of these measures have limitations as analytical tools and should not be considered in isolation, or as a substitute for analysis of our results as reported under GAAP. Because not all companies use identical calculations, the presentations of these measures may not be comparable to other similarly titled measures of other companies and can differ significantly from company to company. For a discussion of the use of these measures and a reconciliation of the most directly comparable GAAP measures, see “Summary—Summary Historical Financial and Other Data.”

RISK FACTORS

Investing in our common stock involves a high degree of risk. You should carefully consider all of the risks and uncertainties described below and the other information set forth in this prospectus and in our Annual Report on Form 10-K for the fiscal year ended December 31, 2024 before deciding to invest in shares of our common stock. If any of the following risks actually occurs, our business, results of operations, prospects, and financial condition may be materially adversely affected. In such case, the trading price of our common stock could decline, and you may lose all or part of your investment. Some statements in this prospectus, including statements in the following risk factors, constitute forward-looking statements. See “Forward-looking Statements.”

Risks Related to this Offering and Ownership of our Common Stock

The Institutional Investors will continue to hold a significant percentage of our outstanding common stock after this offering and their interests may be different than the interests of other holders of our securities.

Upon the completion of this offering, the Institutional Investors will own approximately    % of our outstanding common stock, or approximately    % if the underwriters exercise in full their option to purchase additional shares. As a result, the Institutional Investors are able to control or influence actions to be taken by us, including future issuances of our common stock or other securities, the payment of dividends, if any, on our common stock, amendments to our organizational documents, and the approval of significant corporate transactions, including mergers, sales of substantially all of our assets, distributions of our assets, the incurrence of indebtedness, and any incurrence of liens on our assets.

The interests of the Institutional Investors may be materially different than the interests of our other stakeholders. In addition, the Institutional Investors may have an interest in pursuing acquisitions, divestitures, and other transactions that, in their judgment, could enhance their investment, even though such transactions might involve risks to you. For example, the Institutional Investors may cause us to take actions or pursue strategies that could impact our ability to make payments under our Credit Facilities or cause a change of control. In addition, to the extent permitted by agreements governing our Credit Facilities, the Institutional Investors may cause us to pay dividends rather than make capital expenditures or repay debt. The Institutional Investors are in the business of making investments in companies and may from time to time acquire and hold interests in businesses that compete directly or indirectly with us. Our amended and restated certificate of incorporation provides that none of the Institutional Investors, any of their respective affiliates, or any director who is not employed by us (including any non-employee director who serves as one of our officers in both his director and officer capacities) or his or her affiliates will have any duty to refrain from engaging, directly or indirectly, in the same business activities or similar business activities or lines of business in which we operate. The Institutional Investors also may pursue acquisition opportunities that may be complementary to our business, and, as a result, those acquisition opportunities may not be available to us.

So long as the Institutional Investors continue to own a significant amount of our outstanding common stock, even if such amount is less than 50%, they will continue to be able to strongly influence or effectively control our decisions and, so long as each of the Institutional Investors continues to own shares of our outstanding common stock, they will have the ability to nominate individuals to our board of directors. See “Description of Capital Stock” below and the section entitled “Certain Relationships and Related Transactions and Director Independence—Stockholders Agreement” included in our Annual Report on Form 10-K for the fiscal year ended December 31, 2024 and incorporated by reference herein. In addition, the Institutional Investors, acting together, will be able to determine the outcome of all matters requiring stockholder approval and will be able to cause or prevent a change of control of our company or a change in the composition of our board of directors and could preclude any unsolicited acquisition of our company. The concentration of ownership could deprive you of an opportunity to receive a premium for your shares of common stock as part of a sale of our company and ultimately might affect the market price of our common stock.

We are an “emerging growth company” and we cannot be certain if the reduced disclosure requirements applicable to “emerging growth companies” will make our common stock less attractive to investors.

We are an “emerging growth company,” as defined in Section 2(a)(19) of the Securities Act, and we may take advantage of certain exemptions and relief from various reporting requirements that are applicable

 

15

CONFIDENTIAL TREATMENT REQUESTED

PURSUANT TO 17 C.F.R. SECTION 200.83

to other public companies that are not “emerging growth companies.” In particular, while we are an “emerging growth company,” among other exemptions:

•

we will not be required to engage an independent registered public accounting firm to report on our internal controls over financial reporting pursuant to Section 404(b) of the Sarbanes-Oxley Act;

​

•

we will be subject to reduced disclosure obligations regarding executive compensation in our periodic reports and proxy statements;

​

•

we will not be required to comply with the requirement in Public Company Accounting Oversight Board Auditing Standard 3101, The Auditor’s Report on an Audit of Financial Statements When the Auditor Expresses an Unqualified Opinion, to communicate critical audit matters in the auditor’s report;

​

•

we will be permitted to present only two years of audited financial statements and only two years of related “Management’s Discussion and Analysis of Financial Condition and Results of Operations” in our periodic reports and registration statements, including in this prospectus;

​

•

we will not be required to disclose certain executive compensation related items such as the correlation between executive compensation and performance and comparisons of the chief executive officer’s compensation to median employee compensation; and

​

•

we will not be required submit certain executive compensation matters to stockholder advisory votes, such as “say-on-pay,” “say-on-frequency,” and “say-on-golden parachutes.”

​

In addition, Section 107 of the JOBS Act provides that an emerging growth company can take advantage of the extended transition period provided in Section 7(a)(2)(B) of the Securities Act for complying with new or revised accounting standards, meaning that we can delay the adoption of certain accounting standards until those standards would otherwise apply to private companies. We have elected to take advantage of this extended transition period, and as a result, our financial statements may not be comparable with similarly situated public companies.

We will remain an “emerging growth company” until the earliest to occur of (1) our reporting of $1.24 billion or more in annual gross revenue; (2) our becoming a “large accelerated filer,” with at least $700 million of equity securities held by non-affiliates; (3) our issuance, in any three year period, of more than $1.0 billion in non-convertible debt; and (4) the fiscal year end following the fifth anniversary of the completion of our initial public offering.

We cannot predict whether investors will find our common stock less attractive if we rely on the exemptions and relief granted by the JOBS Act. For example, if we do not adopt a new or revised accounting standard, our future results of operations may not be as comparable to the results of operations of certain other companies in our industry that adopted such standards. If some investors find our common stock less attractive as a result, there may be a less active trading market for our common stock, and our stock price may decline and/or become more volatile.

We have incurred significant increased costs and become subject to additional regulations and requirements as a result of becoming a public company, and our management is required to devote substantial time to compliance matters.

As a public company, we have incurred and will continue to incur significant legal, regulatory, finance, accounting, investor relations, and other expenses that we did not incur as a private company, including costs associated with public company reporting requirements and costs of recruiting and retaining non- executive directors. We also have incurred and will continue to incur costs associated with the Sarbanes- Oxley Act and the Dodd-Frank Act, and related rules implemented by the SEC, and Nasdaq. The expenses incurred by public companies for reporting and corporate governance purposes have been increasing. These rules and regulations have increased our legal and financial compliance costs and have made some activities more time-consuming and costly. Our management devotes a substantial amount of time to ensure that we comply with all of these requirements, diverting the attention of management away from revenue- producing activities. These laws and regulations also could make it more difficult or costly for us to obtain certain types of insurance, including director and officer liability insurance, and we may be forced to accept reduced

 

16

CONFIDENTIAL TREATMENT REQUESTED

PURSUANT TO 17 C.F.R. SECTION 200.83

policy limits and coverage or incur substantially higher costs to obtain the same or similar coverage. These laws and regulations could also make it more difficult for us to attract and retain qualified persons to serve on our board of directors, our board committees, or as our executive officers. Furthermore, if we are unable to satisfy our obligations as a public company, we could be subject to delisting of our common stock, fines, sanctions, and other regulatory action and potentially civil litigation.

Failure to comply with requirements to design, implement, and maintain effective internal controls could have a material adverse effect on our business and stock price.

As a public company, we are subject to significant requirements for enhanced financial reporting and internal controls. The process of designing and implementing effective internal controls is a continuous effort that requires us to anticipate and react to changes in our business and the economic and regulatory environments and to expend significant resources to maintain a system of internal controls that is adequate to satisfy our reporting obligations as a public company. If we are unable to establish or maintain appropriate internal financial reporting controls and procedures, it could cause us to fail to meet our reporting obligations on a timely basis, result in material misstatements in our consolidated financial statements, and harm our results of operations. In addition, we are required, pursuant to Section 404(a) of the Sarbanes-Oxley Act (“Section 404”), to furnish a report by management on, among other things, the effectiveness of our internal control over financial reporting in the second annual report following the completion of our initial public offering. This assessment must include disclosure of any material weaknesses identified by our management in our internal control over financial reporting. The rules governing the standards that must be met for our management to assess our internal control over financial reporting are complex and require significant documentation, testing, and possible remediation. Testing and maintaining internal controls may divert our management’s attention from other matters that are important to our business. Once we are no longer an “emerging growth company,” our auditors will be required to issue an attestation report on the effectiveness of our internal controls on an annual basis.

In connection with the implementation of the necessary procedures and practices related to internal control over financial reporting, we may identify deficiencies that we may not be able to remediate in time to meet the deadline imposed by the Sarbanes-Oxley Act for compliance with the requirements of Section 404. In addition, we may encounter problems or delays in completing the remediation of any deficiencies identified by us or our independent registered public accounting firm in connection with the issuance of their attestation report. Our testing, or the subsequent testing (if required) by our independent registered public accounting firm, may reveal deficiencies in our internal controls over financial reporting that are deemed to be material weaknesses. Any material weaknesses could result in a material misstatement of our annual or quarterly financial statements or disclosures that may not be prevented or detected.

We may not be able to conclude on an ongoing basis that we have effective internal control over financial reporting in accordance with Section 404 or our independent registered public accounting firm may not issue an unqualified opinion. If either we are unable to conclude that we have effective internal control over financial reporting or our independent registered public accounting firm is unable to provide us with an unqualified report (to the extent it is required to issue a report), investors could lose confidence in our reported financial information, which could have a material adverse effect on the trading price of our common stock.

The market price of our common stock has been volatile and may continue to fluctuate substantially, which could result in substantial losses for purchasers of our common stock.

The stock market has experienced extreme volatility in the past. This volatility often has been unrelated or disproportionate to the operating performance of particular companies. Since shares of our common stock were sold in our initial public offering in June 2024 at a price of $21.50 per share, the market price of our common stock has fluctuated, and it may continue to fluctuate substantially due to a number of factors such as those listed in “—Risks Related to our Business and our Industry” and the following:

•

results of operations that vary from the expectations of securities analysts and investors;

​

•

results of operations that vary from those of our competitors;

​

 

17

CONFIDENTIAL TREATMENT REQUESTED

PURSUANT TO 17 C.F.R. SECTION 200.83

•

changes in expectations as to our future financial performance, including financial estimates and investment recommendations by securities analysts and investors, or failure of securities analysts to initiate or maintain coverage of our common stock;

​

•

changes in economic conditions for companies in our industry;

​

•

changes in market valuations of, or earnings and other announcements by, companies in our industry;

​

•

declines in the market prices of stocks generally, particularly those of healthcare technology companies or SaaS companies regardless of industry;

​

•

additions or departures of key management personnel;

​

•

strategic actions by us or our competitors;

​

•

announcements by us, our competitors, dispositions, joint ventures, other strategic relationships, or capital commitments;

​

•

future sales of our common stock by our officers, directors, and significant stockholders;

​

•

expiration of market standoff or lock-up agreements;

​

•

changes in preference of our clients and our market share;

​

•

changes in general economic or market conditions or trends in our industry or the economy as a whole;

​

•

changes in business or regulatory conditions;

​

•

future sales of our common stock or other securities;

​

•

investor perceptions of or the investment opportunity associated with our common stock relative to other investment alternatives;

​

•

the public’s response to press releases or other public announcements by us or third parties, including our filings with the SEC;

​

•

changes or proposed changes in laws or regulations or differing interpretations or enforcement thereof affecting our business;

​

•

announcements, claims and/or allegations relating to litigation, governmental investigations, or compliance with applicable laws and regulations;

​

•

guidance, if any, that we provide to the public, any changes in this guidance, or our failure to meet this guidance;

​

•

the development and sustainability of an active trading market for our stock;

​

•

changes in accounting principles; and

​

•

other events or factors, including those resulting from informational technology system failures and disruptions, data security incidents or breaches, natural disasters, war, including the ongoing conflict in Ukraine, acts of terrorism, or responses to these events.

​

Furthermore, the stock markets in general have experienced extreme volatility that, in some cases, may be unrelated or disproportionate to the operating performance of particular companies. These broad market and industry fluctuations may adversely affect the market price of our common stock, regardless of our actual operating performance. In addition, price volatility may be greater if the public float and trading volume of our common stock are low.

In the past, following periods of market volatility, stockholders have instituted securities class action litigation. If we were to become involved in securities litigation, it could have a substantial cost and divert resources and the attention of executive management from our business regardless of the outcome of such litigation.

Your percentage ownership in us may be diluted by future issuances of our common stock, which could reduce your influence over matters on which stockholders vote.

After this offering we will have approximately 2.3 billion shares of common stock authorized but unissued. Our amended and restated certificate of incorporation authorizes us to issue these shares of common stock, other equity or equity-linked securities, options, and other equity awards relating to our common stock for the consideration and on the terms and conditions established by our board of directors in its sole discretion, whether in connection with acquisitions or otherwise. Issuances of common stock or voting preferred stock would reduce your influence over matters on which our stockholders vote, and, in the case of issuances of preferred stock, would likely result in your interest in us being subject to the prior rights of holders of that preferred stock, if any.

We have reserved, or will reserve in the future, shares for issuance (i) for outstanding awards under our 2019 Stock Incentive Plan and for grants under our 2024 Equity Incentive Plan and (ii) under our 2024 Employee Stock Purchase Plan. See “Executive Compensation—Equity Awards” included in our Annual Report on Form 10-K for the fiscal year ended December 31, 2024 and incorporated by reference herein. Any common stock that we issue, including under our 2019 Stock Incentive Plan, 2024 Equity Incentive Plan, 2024 Employee Stock Purchase Plan, or other equity incentive plans that we may adopt in the future, would dilute the percentage ownership held by the investors who purchase common stock in this offering. In the future, we may also issue our securities in connection with investments or acquisitions. The amount of shares of our common stock issued in connection with an investment or acquisition could constitute a material portion of our then- outstanding shares of our common stock. Any issuance of additional securities in connection with investments or acquisitions may result in additional dilution to you.

Because we have no current plans to pay cash dividends on our common stock, you may not receive any return on investment unless you sell your shares of common stock for a price greater than that which you paid for it.

We have no current plans to pay cash dividends on our common stock. The declaration, amount, and payment of any future dividends will be at the sole discretion of our board of directors, and will depend on, among other things, general and economic conditions, our results of operations and financial condition, our available cash and current and anticipated cash needs, capital requirements, contractual, legal, tax, and regulatory restrictions and implications on the payment of dividends by us to our stockholders or by our subsidiaries to us, including restrictions under our credit agreements and other indebtedness we may incur, and such other factors as our board of directors may deem relevant. See “Dividend Policy.”

As a result, you may not receive any return on an investment in our common stock unless you sell our common stock for a price greater than your purchase price.

Future sales, or the perception of future sales, by us or our existing stockholders in the public market following the completion of this offering could cause the market price for our common stock to decline.

The sale of substantial amounts of shares of our common stock in the public market after this offering, or the perception that such sales could occur, could harm the prevailing market price of shares of our common stock. These sales, or the possibility that these sales may occur, also might make it more difficult for us to sell equity securities in the future at a time and at a price that we deem appropriate.

The selling stockholders and certain of our executive officers and directors have signed lock-up agreements in connection with this offering that restrict the sale of the shares of our common stock and certain other securities held by them for   days from the date of this prospectus except with the prior written consent of J.P. Morgan Securities LLC and Goldman Sachs & Co. LLC. Upon the expiration of such lock-up agreements, all of the outstanding         shares (or        shares, if the underwriters exercise their option to purchase additional shares in full) held by the selling stockholders, certain executive officers and directors will be eligible for resale in a public market, subject to vesting in some cases and to volume, manner of sale and other limitations under Rule 144.

In addition, pursuant to the Amended and Restated Registration Rights Agreement, dated as of June 10, 2024, by and among Waystar Holding Corp. and the other parties named therein, certain of our existing stockholders have the right, subject to certain conditions, to require us to register the sale of their

 

19

CONFIDENTIAL TREATMENT REQUESTED

PURSUANT TO 17 C.F.R. SECTION 200.83

shares of our common stock under the Securities Act. See “Certain Relationships and Related Transactions and Director Independence—Registration Rights Agreement” included in our Annual Report on Form 10-K for the fiscal year ended December 31, 2024 and incorporated by reference herein. By exercising their demand registration rights and selling a large number of shares, such existing stockholders could cause the prevailing market price of our common stock to decline. Following completion of this offering, the shares covered by demand registration rights would represent approximately    % of common stock outstanding (or    % if the underwriters exercise in full their option to purchase additional shares). Registration of any of these outstanding shares of our common stock would result in such shares becoming freely tradable without compliance with Rule 144 upon effectiveness of the registration statement. See “Shares Eligible for Future Sale.”

We filed a registration statement on Form S-8 under the Securities Act to register common stock issued or reserved for issuance under our 2019 Stock Incentive Plan, 2024 Equity Incentive Plan, and 2024 Employee Stock Purchase Plan, which automatically became effective upon filing. Accordingly, shares registered under such registration statement are available for sale in the open market, unless such shares are subject to vesting restrictions or lock-up restrictions.

As restrictions on resale end, or if the existing stockholders exercise their registration rights, the market price of our shares of common stock could drop significantly if the holders of these restricted shares sell them or are perceived by the market as intending to sell them. These factors could also make it more difficult for us to raise additional funds through future offerings of our shares of common stock or other securities.

If securities analysts do not publish research or reports about our business or if they downgrade our stock or our sector, our stock price and trading volume could decline.

The trading market for our common stock depends in part on the research and reports that industry or financial analysts publish about us or our business. We do not control these analysts. Furthermore, if one or more of the analysts who do cover us downgrade our stock or our industry, or the stock of any of our competitors, or publish inaccurate or unfavorable research about our business, the price of our stock could decline. If one or more of these analysts ceases coverage of us or fails to publish reports on us regularly, we could lose visibility in the market, which in turn could cause our stock price or trading volume to decline.

Anti-takeover provisions in our organizational documents could delay or prevent a change of control.

Certain provisions of our amended and restated certificate of incorporation and amended and restated bylaws may have an anti-takeover effect and may delay, deter, or prevent a merger, acquisition, tender offer, takeover attempt, or other change of control transaction that a stockholder might consider in its best interest, including those attempts that might result in a premium over the market price for the shares held by our stockholders. These provisions provide for, among other things:

•

a classified board of directors until the second annual meeting of stockholders after the date on which the Institutional Investors collectively own less than 15% in voting power of the then- outstanding power of the then-outstanding shares of stock of our Company entitled to vote generally in the election of directors, as a result of which our board of directors will be divided into three classes until such time, with each class serving for staggered three-year terms;

​

•

the ability of our board of directors to issue one or more series of preferred stock;

​

•

advance notice requirements for nominations of directors by stockholders and for stockholders to include matters to be considered at our annual meetings;

​

•

certain limitations on convening special stockholder meetings and taking stockholder action by written consent;

​

•

during the Protective Period (as defined in “Description of Capital Stock”), the removal of directors only for cause and only upon the affirmative vote of the holders of at least 662∕3% of the shares of common stock entitled to vote generally in the election of directors; and

​

•

during the Protective Period, the required approval of at least 662∕3% of the voting power of the outstanding shares of capital stock entitled to vote generally in the election of directors, voting

together as a single class, to adopt, amend, or repeal certain provisions of our amended and restated certificate of incorporation.

Further, EQT, CPPIB, and Bain each currently has the right to nominate to our board of directors one nominee for so long as each such Institutional Investor beneficially owns 5% or greater of our then-outstanding common stock. See “Description of Capital Stock—Anti-takeover Effects of Our Amended and Restated Certificate of Incorporation and Amended and Restated Bylaws, and Certain Provisions of Delaware Law—Director nomination rights.”

These anti-takeover provisions could make it more difficult for a third party to acquire us, even if the third party’s offer may be considered beneficial by many of our stockholders. These provisions also may have the effect of preventing changes in our board of directors and may make it more difficult to accomplish transactions that stockholders may otherwise deem to be in their best interests. As a result, our stockholders may be limited in their ability to obtain a premium for their shares. See “Description of Capital Stock.”

Our board of directors is authorized to issue and designate shares of our preferred stock in additional series without stockholder approval.

Our amended and restated certificate of incorporation authorizes our board of directors, without the approval of our stockholders, to issue 100,000,000 shares of our preferred stock, subject to limitations prescribed by applicable law, rules and regulations and the provisions of our amended and restated certificate of incorporation, as shares of preferred stock in series, to establish from time to time the number of shares to be included in each such series and to fix the designation, powers, preferences, and rights of the shares of each such series, and the qualifications, limitations, or restrictions thereof. The powers, preferences, and rights of these additional series of preferred stock may be senior to or on parity with our common stock, which may reduce its value.

Our amended and restated certificate of incorporation provides that the Court of Chancery of the State of Delaware (or if such court does not have jurisdiction, another state or the federal courts (as appropriate) located within the State of Delaware) will be the sole and exclusive forum for certain stockholder litigation matters, which could limit our stockholders’ ability to obtain a favorable judicial forum for disputes with us or our directors, officers, employees, or stockholders.

Our amended and restated certificate of incorporation provides that unless we consent to the selection of an alternative forum, the Court of Chancery of the State of Delaware (or if such court does not have jurisdiction, another state or the federal courts (as appropriate) located within the State of Delaware) shall, to the fullest extent permitted by law, be the sole and exclusive forum for any (i) derivative action or proceeding brought on behalf of us, (ii) action asserting a claim of breach of a fiduciary duty owed by any current or former director, officer, or other employee or stockholder of ours to us or our stockholders, (iii) action asserting a claim against us or any director or officer of ours arising pursuant to any provision of the DGCL, or our amended and restated certificate of incorporation or our amended and restated bylaws or as to which the DGCL confers jurisdiction on the Court of Chancery of the State of Delaware, or (iv) action asserting a claim governed by the internal affairs doctrine of the State of Delaware. Our amended and restated certificate of incorporation further provides that, unless we consent in writing to the selection of an alternative forum, to the fullest extent permitted by law, the federal district courts of the United States of America will be the exclusive forum for the resolution of any complaint asserting a cause of action arising under the federal securities laws of the United States, including any claims under the Securities Act and the Exchange Act. However, Section 22 of the Securities Act creates concurrent jurisdiction for federal and state courts over all suits brought to enforce a duty or liability created by the Securities Act or the rules and regulations thereunder and accordingly, we cannot be certain that a court would enforce such provision. See “Description of Capital Stock—Exclusive Forum.”

Any person or entity purchasing or otherwise acquiring any interest in shares of our capital stock shall be deemed to have notice of and consented to the forum provisions in our amended and restated certificate of incorporation, except our stockholders will not be deemed to have waived (and cannot waive) compliance with the federal securities laws and the rules and regulations thereunder. This choice of forum provision may limit a stockholder’s ability to bring a claim in a judicial forum that it finds favorable for disputes with us or any of our directors, officers, other employees, or stockholders which may discourage lawsuits with

respect to such claims. Alternatively, if a court were to find the choice of forum provision contained in our amended and restated certificate of incorporation to be inapplicable or unenforceable in an action, we may incur additional costs associated with resolving such action in other jurisdictions, which could harm our business, results of operations, and financial condition.

PRINCIPAL AND SELLING STOCKHOLDERS

The following table contains information about the beneficial ownership of our common stock as of March 31, 2025, (i) immediately prior to the consummation of this offering and (ii) as adjusted to reflect the sale of shares of our common stock offered by this prospectus by:

•

each individual or entity known by us to beneficially own more than 5% of our outstanding common stock;

​

•

each named executive officer;

​

•

each of our directors;

​

•

all of our directors and executive officers as a group; and

​

•

all selling stockholders.

​

Our calculation of the percentage of beneficial ownership prior to and after the offering is based on         shares of our outstanding common stock as of March 31, 2025.

Beneficial ownership and percentage ownership are determined in accordance with the rules and regulations of the SEC. Under SEC rules, a person is deemed to be a “beneficial owner” of a security if that person has or shares voting power or investment power, which includes the power to dispose of or to direct the disposition of such security. A person is also deemed to be a beneficial owner of any securities of which that person has a right to acquire beneficial ownership within 60 days. Securities that can be so acquired are deemed to be outstanding for purposes of computing such person’s ownership percentage, but not for purposes of computing any other person’s percentage. Under these rules, more than one person may be deemed to be a beneficial owner of the same securities and a person may be deemed to be a beneficial owner of securities as to which such person has no economic interest. Except as indicated in the footnotes to the following table or pursuant to applicable community property laws, we believe, based on information furnished to us, that each stockholder named in the table has sole voting and investment power with respect to the shares set forth opposite such stockholder’s name.

For further information regarding material transactions between us and certain of our stockholders, see “Certain Relationships and Related Transactions and Director Independence” included in our Annual Report on Form 10-K for the fiscal year ended December 31, 2024 and incorporated by reference herein.

DESCRIPTION OF CAPITAL STOCK

The following is a description of the material terms of, and is qualified in its entirety by, our amended and restated certificate of incorporation and amended and restated bylaws, which are filed as exhibits to the registration statement of which this prospectus is a part. For a complete description of our capital stock, you should refer to our amended and restated certificate of incorporation, amended and restated bylaws, and the applicable provisions of Delaware law. In this section, “we,” “us,” “our,” “the Company” and “our Company” refer to Waystar Holding Corp. and not to any of its subsidiaries and “Institutional Investors” refers to EQT, CPPIB, and Bain, in each case, so long as they own shares of common stock of our Company.

Our purpose is to engage in any lawful act or activity for which corporations may be organized under the DGCL. Our authorized capital stock consists of 2,500,000,000 shares of our common stock, $0.01 par value per share; and 100,000,000 shares of preferred stock, par value $0.01 per share. No shares of preferred stock will be issued or outstanding immediately after the offering contemplated by this prospectus. Unless our board of directors determines otherwise, we will issue all shares of our capital stock in uncertificated form.

Common Stock

Voting rights

Each holder of our common stock is entitled to one vote per share on all matters submitted to a vote of the stockholders. The holders of our common stock do not have cumulative voting rights in the election of directors.

Dividend rights

The holders of our common stock are entitled to receive dividends as may be declared from time to time by our board of directors out of legally available funds. See the section titled “Dividend Policy” for additional information.

Liquidation

In the event of our liquidation, dissolution, or winding up and after payment in full of all amounts required to be paid to creditors and to the holders of preferred stock having liquidation preferences, if any, holders of our common stock will be entitled to share ratably in the net assets legally available for distribution to stockholders.

Rights and preferences

Holders of our common stock have no preemptive, conversion, or subscription rights, and there are no redemption or sinking fund provisions applicable to our common stock.

Fully paid and non-assessable

All shares of our common stock that will be outstanding at the time of the completion of the offering will be fully paid and non-assessable.

The rights, powers, preferences, and privileges of holders of our common stock will be subject to those of the holders of any shares of our preferred stock we may authorize and issue in the future.

Preferred Stock

Our amended and restated certificate of incorporation authorizes our board of directors to establish one or more series of preferred stock (including convertible preferred stock). Unless required by law or by the applicable stock exchange, the authorized shares of preferred stock will be available for issuance without further action by you. Our board of directors may determine, with respect to any series of preferred stock, the terms and rights of that series, including:

 

32

CONFIDENTIAL TREATMENT REQUESTED

PURSUANT TO 17 C.F.R. SECTION 200.83

•

the designation of the series;

​

•

the number of shares of the series, which our board of directors may, except where otherwise provided in the preferred stock designation, increase (but not above the total number of authorized shares of the class) or decrease (but not below the number of shares then outstanding);

​

•

whether dividends, if any, will be cumulative or non-cumulative and the dividend rate of the series;

​

•

the dates at which dividends, if any, will be payable;

​

•

the redemption rights and price or prices, if any, for shares of the series;

​

•

the terms and amounts of any sinking fund provided for the purchase or redemption of shares of the series;

​

•

the amounts payable on shares of the series in the event of any voluntary or involuntary liquidation, dissolution or winding-up of the affairs of the Company;

​

•

whether the shares of the series will be convertible into shares of any other class or series, or any other security, of the Company or any other corporation and, if so, the specification of the other class or series or other security, the conversion price or prices or rate or rates, any rate adjustments, the date or dates as of which the shares will be convertible and all other terms and conditions upon which the conversion may be made;

​

•

restrictions on the issuance of shares of the same series or of any other class or series of our capital stock; and

​

•

the voting rights, if any, of the holders of the series.

​

We may issue a series of preferred stock that could, depending on the terms of the series, impede or discourage an acquisition attempt or other transaction that some, or a majority, of the holders of our common stock might believe to be in their best interests or in which the holders of our common stock might receive a premium for their common stock over the market price of the common stock. In addition, the issuance of preferred stock may adversely affect the holders of our common stock by restricting dividends on the common stock, diluting the voting power of the common stock or subordinating the liquidation rights of the common stock. In addition, the issuance of preferred stock could have the effect of delaying, deferring, or preventing a change of control, or other corporate action. As a result of these or other factors, the issuance of preferred stock may have an adverse impact on the market price of our common stock.

Dividends

The DGCL permits a corporation to declare and pay dividends out of “surplus” or, if there is no “surplus,” out of its net profits for the fiscal year in which the dividend is declared and/or the preceding fiscal year. “Surplus” is defined as the excess of the net assets of the corporation over the amount determined to be the capital of the corporation by our board of directors. The capital of the corporation is typically calculated to be (and cannot be less than) the aggregate par value of all issued shares of capital stock. Net assets equal the fair value of the total assets minus total liabilities. The DGCL also provides that dividends may not be paid out of net profits if, after the payment of the dividend, capital is less than the capital represented by the outstanding stock of all classes having a preference upon the distribution of assets.

Declaration and payment of any dividend will be subject to the discretion of our board of directors. The time and amount of dividends will be dependent upon our financial condition, operations, cash requirements, and availability, debt repayment obligations, capital expenditure needs, and restrictions in our debt instruments, industry trends, the provisions of Delaware law affecting the payment of dividends to stockholders and any other factors our board of directors may consider relevant.

Anti-takeover Effects of Our Amended and Restated Certificate of Incorporation and Amended and Restated Bylaws, and Certain Provisions of Delaware Law

Our amended and restated certificate of incorporation, amended and restated bylaws, and the DGCL, which are summarized in the following paragraphs, contain provisions that are intended to enhance the

 

33

CONFIDENTIAL TREATMENT REQUESTED

PURSUANT TO 17 C.F.R. SECTION 200.83

likelihood of continuity and stability in the composition of our board of directors. These provisions are intended to avoid costly takeover battles, reduce our vulnerability to a hostile change of control, and enhance the ability of our board of directors to maximize stockholder value in connection with any unsolicited offer to acquire us. However, these provisions may have an anti-takeover effect and may delay, deter, or prevent a merger or acquisition of the Company by means of a tender offer, a proxy contest, or other takeover attempt that a stockholder might consider is in its best interest, including those attempts that might result in a premium over the prevailing market price for the shares of common stock held by stockholders.

Authorized but unissued capital stock

Delaware law does not require stockholder approval for any issuance of authorized shares. However, the listing requirements of Nasdaq, which apply so long as our common stock remains listed on Nasdaq, require stockholder approval of certain issuances equal to or exceeding 20% of the then-outstanding voting power or then-outstanding number of shares of common stock. These additional shares may be used for a variety of corporate purposes, including future public offerings to raise additional capital or to facilitate acquisitions.

Our board of directors may issue shares of preferred stock on terms calculated to discourage, delay, or prevent a change of control of the Company or the removal of our management. Moreover, our authorized but unissued shares of preferred stock are available for future issuances without stockholder approval and could be utilized for a variety of corporate purposes, including future offerings to raise additional capital, acquisitions, or employee benefit plans.

One of the effects of the existence of unissued and unreserved common stock or preferred stock may be to enable our board of directors to issue shares to persons friendly to current management, which issuance could render more difficult or discourage an attempt to obtain control of the Company by means of a merger, tender offer, proxy contest, or otherwise, and thereby protect the continuity of our management and possibly deprive our stockholders of opportunities to sell their shares of common stock at prices higher than prevailing market prices.

Director nomination rights

Our amended and restated certificate of incorporation provides that our board of directors will consist of not more than ten members and not less than the number of directors as is required to allow for the election of each director nominee as described below. EQT will have the right to nominate to our board of directors (i) two nominees for so long as EQT beneficially owns 25% or greater of our then-outstanding common stock, and (ii) one nominee for so long as EQT beneficially owns 5% or greater, but less than 25% of our then- outstanding common stock. CPPIB will have the right to nominate to our board of directors one nominee for so long as CPPIB beneficially owns 5% or greater of our then-outstanding common stock. Bain will have the right to nominate to our board of directors one nominee for so long as Bain beneficially owns 5% or greater of our then-outstanding common stock. In addition, we will cause the nomination of five independent director nominees as well as the nomination of the person who, as of the date of nomination, is then- serving as our Chief Executive Officer. As of the date of this prospectus, each of EQT, CPPIB, and Bain has the right to one director nominee pursuant to the foregoing director nomination rights.

In addition, EQT will have the right to designate the chairperson of our board of directors for so long as it beneficially owns at least 20% of our then-outstanding common stock, with the consent of CPPIB (not to be unreasonably withheld).

Further, for so long as EQT, CPPIB, and Bain collectively beneficially own 5% or greater of our then- outstanding common stock, (i) the Bain director nominee will be appointed to serve on the Audit, Compliance, & Risk Committee, (ii) the CPPIB director nominee and one EQT director nominee will be appointed to serve on the Talent & Compensation Committee, and (iii) the CPPIB director nominee and one EQT director nominee will be appointed to serve on the Nominating and Corporate Governance Committee, subject to certain exceptions.

Classified board of directors

Our amended and restated certificate of incorporation provides that, subject to the right of holders of any series of preferred stock, our board of directors will be divided into three classes of directors, with the

 

34

CONFIDENTIAL TREATMENT REQUESTED

PURSUANT TO 17 C.F.R. SECTION 200.83

classes to be as nearly equal in number as possible, and with the directors serving three-year terms, with only one class of directors being elected at each annual meeting of stockholders. At the second annual meeting of stockholders after the date on which the Institutional Investors collectively own less than 15% in voting power of the then-outstanding power of the then-outstanding shares of stock of our Company entitled to vote generally in the election of directors (the “Triggering Annual Meeting”), and each annual meeting of stockholders thereafter, all directors shall be elected to hold office for a one-year term expiring at the next annual meeting of stockholders. Pursuant to such procedures, effective as of the Triggering Annual Meeting, our board of directors will no longer be classified under Section 141(d) of the DGCL and directors shall no longer be divided into three classes. As a result, prior to the Triggering Annual Meeting, approximately one-third of our board of directors will be elected each year. The classification of directors prior to the Triggering Annual Meeting has the effect of making it more difficult for stockholders to change the composition of our board of directors. Our amended and restated certificate of incorporation and amended and restated bylaws provide that, subject to any rights of holders of preferred stock to elect additional directors under specified circumstances, the number of directors will be fixed from time to time exclusively pursuant to a resolution adopted by our board of directors; however, if at any time the Institutional Investors collectively own at least 40% in voting power of the then-outstanding shares of stock of our Company entitled to vote generally in the election of directors, the stockholders may also fix the number of directors.

Business combinations

We have opted out of Section 203 of the DGCL; however, our amended and restated certificate of incorporation contains similar provisions providing that we may not engage in certain “business combinations” with any “interested stockholder” for a three-year period following the time that the stockholder became an interested stockholder, unless:

•

prior to such time, our board of directors approved either the business combination or the transaction that resulted in the stockholder becoming an interested stockholder;

​

•

upon consummation of the transaction which resulted in the stockholder becoming an interested stockholder, the interested stockholder owned at least 85% of our voting stock outstanding at the time the transaction commenced, excluding certain shares;

​

•

at or subsequent to that time, the business combination is approved by our board of directors and by the affirmative vote of holders of at least 662∕3% of our outstanding voting stock that is not owned by the interested stockholder; or

​

•

the stockholder became an interested stockholder inadvertently and (i) as soon as practicable divested itself of sufficient ownership to cease to be an interested stockholder and (ii) had not been an interested stockholder but for the inadvertent acquisition of ownership within three years of the business combination.

​

Generally, a “business combination” includes a merger, asset, or stock sale or other transaction resulting in a financial benefit to the interested stockholder. Subject to certain exceptions, an “interested stockholder” is a person who, together with that person’s affiliates and associates, owns, or within the previous three years owned, 15% or more of our outstanding voting stock. For purposes of this section only, “voting stock” has the meaning given to it in Section 203 of the DGCL.

Under certain circumstances, these provisions make it more difficult for a person who would be an “interested stockholder” to effect various business combinations with our company for a three-year period. These provisions may encourage companies interested in acquiring our Company to negotiate in advance with our board of directors because the stockholder approval requirement would be avoided if our board of directors approves either the business combination or the transaction which results in the stockholder becoming an interested stockholder. These provisions also may have the effect of preventing changes in our board of directors and may make it more difficult to accomplish transactions that stockholders may otherwise deem to be in their best interests.

Our amended and restated certificate of incorporation provides that each of the Institutional Investors, and any of their respective direct or indirect transferees and any group as to which such persons or entities are a party, does not constitute an “interested stockholder” for purposes of these provisions.

Removal of directors; vacancies

Under the DGCL, unless otherwise provided in our amended and restated certificate of incorporation, directors serving on a classified board may be removed by the stockholders only for cause. Our amended and restated certificate of incorporation provides that, other than directors elected by holders of our preferred stock, if any, directors may be removed with or without cause upon the affirmative vote of a majority in voting power of all outstanding shares of stock entitled to vote thereon, voting together as a single class; provided, however, at any time commencing on the day on which the Institutional Investors collectively beneficially own less than 40% in voting power of the then-outstanding shares of stock of our company entitled to vote generally in the election of directors and ending immediately following the final adjournment of the Triggering Annual Meeting (such period, the “Protective Period”), directors may only be removed for cause, and only by the affirmative vote of holders of at least 662∕3% in voting power of all the then-outstanding shares of stock of our company entitled to vote thereon, voting together as a single class. In addition, our amended and restated certificate of incorporation will also provide that, subject to the rights granted to one or more series of preferred stock then outstanding or the rights granted pursuant to the Stockholders Agreement, any newly created directorship on our board of directors that results from an increase in the number of directors and any vacancies on our board of directors will be filled only by the affirmative vote of a majority of the remaining directors, even if less than a quorum, or by a sole remaining director or by the stockholders; provided, however, at any time when the Institutional Investors collectively beneficially own less than 40% in voting power of the then-outstanding shares of stock of our company entitled to vote generally in the election of directors, any newly created directorship on our board of directors that results from an increase in the number of directors and any vacancy occurring in our board of directors may only be filled by a majority of the directors then in office, although less than a quorum, or by a sole remaining director (and not by the stockholders). Our amended and restated certificate of incorporation provides that our board of directors may increase the number of directors by the affirmative vote of a majority of the directors or, at any time when the Institutional Investors collectively beneficially own at least 40% of the voting power of the then-outstanding shares of stock of our Company entitled to vote generally in the election of directors, of the stockholders.

Notwithstanding the foregoing, EQT, CPPIB, or Bain, as applicable, shall have the exclusive right to remove their respective nominees from our board of directors, with or without cause. For so long as EQT, CPPIB, or Bain have the right to nominate their respective directors, the shares of common stock held by EQT, CPPIB, or Bain, as applicable, shall be the only shares entitled to vote on the removal without cause of any of their respective nominees, and the shares of common stock owned by any holders as of the record date for determining stockholders entitled to vote thereon shall have no voting rights on such matter.

No cumulative voting

Under Delaware law, the right to vote cumulatively does not exist unless the certificate of incorporation specifically authorizes cumulative voting. Our amended and restated certificate of incorporation does not authorize cumulative voting. Therefore, stockholders holding a majority in voting power of the then- outstanding shares of our stock entitled to vote generally in the election of directors are able to elect all of our directors.

Special stockholder meetings

Our amended and restated certificate of incorporation provides that special meetings of our stockholders may be called at any time only by or at the direction of our board of directors or the chairman of our board of directors; provided, however, at any time when the Institutional Investors beneficially own, in the aggregate, at least 40% in voting power of the then-outstanding shares of stock of our Company entitled to vote generally in the election of directors, special meetings of our stockholders may be called at any time by or at the direction of our board of directors or the chairman of our board of directors and shall be called by the secretary of our company at the request of at least two of the Institutional Investors. Our amended and restated bylaws prohibit the conduct of any business at a special meeting other than as specified in the notice for such meeting. These provisions may have the effect of deferring, delaying, or discouraging hostile takeovers, or changes in control or management of the Company.

Requirements for advance notification of director nominations and stockholder proposals

Our amended and restated bylaws establish advance notice procedures with respect to stockholder proposals and the nomination of candidates for election as directors, other than nominations made as provided in our amended and restated certificate of incorporation, the Stockholders Agreement or by or at the direction of our board of directors or a committee of our board of directors. In order for any matter to be “properly brought” before a meeting, a stockholder will have to comply with advance notice requirements and provide us with certain information. Generally, to be timely, a stockholder’s notice must be received at our principal executive offices not less than 90 days nor more than 120 days prior to the first anniversary date of the immediately preceding annual meeting of stockholders. Our amended and restated bylaws also specify requirements as to the form and content of a stockholder’s notice. Our amended and restated bylaws allow the chairman of the meeting at a meeting of the stockholders to adopt rules and regulations for the conduct of meetings which may have the effect of precluding the conduct of certain business at a meeting if the rules and regulations are not followed. These notice requirements will not apply to the Institutional Investors and their affiliates for as long as the Stockholders Agreement remains in effect. These provisions may also deter, delay, or discourage a potential acquirer from conducting a solicitation of proxies to elect the acquirer’s own slate of directors or otherwise attempting to influence or obtain control of the Company.

Stockholder action by written consent

Pursuant to Section 228 of the DGCL, any action required to be taken at any annual or special meeting of the stockholders may be taken without a meeting, without prior notice and without a vote if a consent or consents in writing, setting forth the action so taken, is signed by the holders of outstanding stock having not less than the minimum number of votes that would be necessary to authorize or take such action at a meeting at which all shares of our stock entitled to vote thereon were present and voted, unless our amended and restated certificate of incorporation provides otherwise. Our amended and restated certificate of incorporation precludes stockholder action by written consent at any time when the Institutional Investors collectively beneficially own less than 40% in voting power of the then-outstanding shares of stock of our Company entitled to vote generally in the election of directors, other than certain rights that holders of our preferred stock may have to act by consent.

Supermajority provisions

Our amended and restated certificate of incorporation and our amended and restated bylaws provide that our board of directors is expressly authorized to make, alter, amend, change, add to, rescind, or repeal, in whole or in part, our amended and restated bylaws without a stockholder vote in any matter not inconsistent with Delaware law or our amended and restated certificate of incorporation. Any amendment, alteration, rescission, or repeal, of our amended and restated bylaws by our stockholders requires the affirmative vote of a majority in voting power of the outstanding shares of our stock present in person or represented by proxy at the meeting of stockholders and entitled to vote on such amendment, alteration, change, addition, rescission, change, addition, or repeal, except that during the Protective Period, any amendment, alteration, rescission, change, addition, or repeal of our amended and restated bylaws by our stockholders will require the affirmative vote of the holders of at least 662∕3% in voting power of all the then- outstanding shares of stock of our Company entitled to vote thereon, voting together as a single class.

The DGCL provides generally that the affirmative vote of a majority of the outstanding shares entitled to vote thereon, voting together as a single class, is required to amend a corporation’s certificate of incorporation, unless the certificate of incorporation requires a greater percentage.

Our amended and restated certificate of incorporation provides that during the Protective Period, the following provisions in our amended and restated certificate of incorporation may be amended, altered, repealed, or rescinded only by the affirmative vote of the holders of at least 662∕3% in voting power of all the then-outstanding shares of stock of our company entitled to vote thereon, voting together as a single class:

•

the provision requiring a 662∕3% supermajority vote for stockholders to amend our amended and restated bylaws;

​

•

the provisions providing for a classified board of directors (the election and term of our directors);

​

 

37

CONFIDENTIAL TREATMENT REQUESTED

PURSUANT TO 17 C.F.R. SECTION 200.83

•

the provisions regarding resignation and removal of directors;

​

•

the provisions regarding competition and corporate opportunities;

​

•

the provisions regarding entering into business combinations with interested stockholders;

​

•

the provisions regarding stockholder action by written consent;

​

•

the provisions regarding calling annual or special meetings of stockholders;

​

•

the provisions regarding filling vacancies on our board of directors and newly created directorships;

​

•

the provisions eliminating monetary damages for breaches of fiduciary duty by a director or officer; and

​

•

the amendment provision requiring that the above provisions be amended only with a 662∕3% supermajority vote.

​

The combination of the classification of our board of directors, the lack of cumulative voting and the supermajority voting requirements will make it more difficult for our existing stockholders to replace our board of directors as well as for another party to obtain control of us by replacing our board of directors. Because our board of directors has the power to retain and discharge our officers, these provisions could also make it more difficult for existing stockholders or another party to effect a change in management.

These provisions may have the effect of deterring hostile takeovers, delaying, or preventing changes in control of our management or the Company, such as a merger, reorganization or tender offer. These provisions are intended to enhance the likelihood of continued stability in the composition of our board of directors and its policies and to discourage certain types of transactions that may involve an actual or threatened acquisition of the Company. These provisions are designed to reduce our vulnerability to an unsolicited acquisition proposal. The provisions are also intended to discourage certain tactics that may be used in proxy fights. However, such provisions could have the effect of discouraging others from making tender offers for our shares and, as a consequence, they also may inhibit fluctuations in the market price of our shares that could result from actual or rumored takeover attempts. Such provisions may also have the effect of preventing changes in management.

Dissenters’ Rights of Appraisal and Payment

Under the DGCL, with certain exceptions, our stockholders will have appraisal rights in connection with a merger or consolidation of us. Pursuant to the DGCL, stockholders who properly request and perfect appraisal rights in connection with such merger or consolidation will have the right to receive payment of the fair value of their shares as determined by the Delaware Court of Chancery.

Stockholders’ Derivative Actions

Under the DGCL, any of our stockholders may bring an action in our name to procure a judgment in our favor, also known as a derivative action, provided that the stockholder bringing the action is a holder of our shares at the time of the transaction to which the action relates or such stockholder’s stock thereafter devolved by operation of law.

Exclusive Forum

Our amended and restated certificate of incorporation provides that unless we consent in writing to the selection of an alternative forum, the Court of Chancery of the State of Delaware (or if such court does not have subject matter jurisdiction another state or the federal court (as appropriate) located within the State of Delaware) shall, to the fullest extent permitted by law, be the sole and exclusive forum for any (i) derivative action or proceeding brought on behalf of our company, (ii) action asserting a claim of breach of a fiduciary duty owed by any current or former director, officer, employee, or stockholder of our company to our company or our company’s stockholders, (iii) action asserting a claim against our company or any current or former director, officer, employee, or stockholder of our company arising pursuant to any provision of the DGCL or our amended and restated certificate of incorporation or our amended and restated bylaws (as either may be amended from time to time) or (iv) action asserting a claim governed by the

 

38

CONFIDENTIAL TREATMENT REQUESTED

PURSUANT TO 17 C.F.R. SECTION 200.83

internal affairs doctrine of the State of Delaware. These provisions shall not apply to suits brought to enforce a duty or liability created by the Exchange Act or any other claim for which the federal courts have exclusive jurisdiction and our stockholders cannot waive compliance with federal securities laws and the rules and regulations thereunder. Our amended and restated certificate of incorporation further provides that, unless we consent in writing to the selection of an alternative forum, to the fullest extent permitted by law, the federal district courts of the United States of America will be the exclusive forum for the resolution of any complaint asserting a cause of action arising under the federal securities laws of the United States, including any claims under the Securities Act and the Exchange Act. Any person or entity purchasing or otherwise acquiring any interest in shares of capital stock of our company shall be deemed to have notice of and consented to the forum provisions in our amended and restated certificate of incorporation. Although our amended and restated certificate of incorporation contains the exclusive forum provision described above, it is possible that a court could find that such a provision is inapplicable for a particular claim or action or that such provision is unenforceable. In particular, Section 22 of the Securities Act creates concurrent jurisdiction for federal and state courts over all suits brought to enforce a duty or liability created by the Securities Act or the rules and regulations thereunder and accordingly, we cannot be certain that a court would enforce such provision. Our exclusive forum provision shall not relieve the Company of its duties to comply with the federal securities laws and the rules and regulations thereunder, and our stockholders will not be deemed to have waived our compliance with these laws, rules and regulations. Further, stockholders may not waive their rights under the Exchange Act, including their right to bring suit.

Conflicts of Interest

Delaware law permits corporations to adopt provisions renouncing any interest or expectancy in certain opportunities that are presented to the corporation or its officers, directors, or stockholders. Our amended and restated certificate of incorporation, to the maximum extent permitted from time to time by Delaware law, renounces any interest or expectancy that we have in, or right to be offered an opportunity to participate in, specified business opportunities that are from time to time presented to our officers, directors, or stockholders or their respective affiliates, other than those officers, directors, stockholders, or affiliates who are our or our subsidiaries’ employees. Our amended and restated certificate of incorporation provides that, to the fullest extent permitted by law, none of the Institutional Investors or any director who is not employed by us (including any non-employee director who serves as one of our officers in both his or her director and officer capacities) or his or her affiliates will have any duty to refrain from (1) engaging in a corporate opportunity in the same or similar business activities or lines of business in which we or our affiliates now engage or propose to engage or (2) otherwise competing with us or our affiliates. In addition, to the fullest extent permitted by law, in the event that any of the Institutional Investors or any non-employee director acquires knowledge of a potential transaction or other business opportunity which may be a corporate opportunity for itself or himself or its or his affiliates or for us or our affiliates, such person will have no duty to communicate or offer such transaction or business opportunity to us or any of our affiliates and they may take any such opportunity for themselves or offer it to another person or entity. Our amended and restated certificate of incorporation does not renounce our interest in any business opportunity that is expressly offered to a non-employee director solely in his or her capacity as a director or officer of the Company. To the fullest extent permitted by law, no business opportunity will be deemed to be a potential corporate opportunity for us unless we would be permitted to undertake the opportunity under our amended and restated certificate of incorporation, we have sufficient financial resources to undertake the opportunity and the opportunity would be in line with our business.

Limitations on Liability and Indemnification of Officers and Directors

The DGCL authorizes corporations to limit or eliminate the personal liability of directors and certain officers to corporations and their stockholders for monetary damages for breaches of directors’ fiduciary duties, subject to certain exceptions. Our amended and restated certificate of incorporation includes a provision that eliminates the personal liability of directors and officers for monetary damages for any breach of fiduciary duty as a director or officer, except to the extent such exemption from liability or limitation thereof is not permitted under the DGCL. The effect of these provisions is to eliminate the rights of us and our stockholders, through stockholders’ derivative suits on our behalf, to recover monetary damages from a director for breach of fiduciary duty as a director, including breaches resulting from grossly negligent behavior. This provision does not limit or eliminate the liability of any officer in any action by or in the right

 

39

CONFIDENTIAL TREATMENT REQUESTED

PURSUANT TO 17 C.F.R. SECTION 200.83

of the Company, including any derivative claims. However, exculpation will not apply to any director if the director has breached the duty of loyalty to the corporation and its stockholders, acted in bad faith, knowingly or intentionally violated the law, authorized illegal dividends or redemptions, or derived an improper benefit from his or her actions as a director.

Our amended and restated bylaws provide that we must generally indemnify, and advance expenses to, our directors and officers to the fullest extent authorized by the DGCL. We also are expressly authorized to carry directors’ and officers’ liability insurance providing indemnification for our directors, officers, and certain employees for some liabilities. We also have entered into indemnification agreements with our directors, which agreements require us to indemnify these individuals to the fullest extent permitted under Delaware law against liabilities that may arise by reason of their service to us, and to advance expenses incurred as a result of any proceeding against them as to which they could be indemnified. We believe that these indemnification and advancement provisions and insurance are useful to attract and retain qualified directors and officers.

The limitation of liability, indemnification, and advancement provisions in our amended and restated certificate of incorporation and amended and restated bylaws may discourage stockholders from bringing a lawsuit against directors or officers for breach of their fiduciary duty. These provisions also may have the effect of reducing the likelihood of derivative litigation against directors and officers, even though such an action, if successful, might otherwise benefit us and our stockholders. In addition, your investment may be adversely affected to the extent we pay the costs of settlement and damage awards against directors and officers pursuant to these indemnification provisions.

There is currently no pending material litigation or proceeding involving any of our directors, officers, or employees for which indemnification is sought.

SHARES ELIGIBLE FOR FUTURE SALE

General

We cannot predict what effect, if any, market sales of shares of common stock or the availability of shares of common stock for sale will have on the market price of our common stock prevailing from time to time. Nevertheless, sales of substantial amounts of common stock, including shares issued upon the exercise of outstanding options, in the public market, or the perception that such sales could occur, could materially and adversely affect the market price of our common stock and could impair our future ability to raise capital through the sale of our equity or equity-related securities at a time and price that we deem appropriate. Furthermore, there may be sales of substantial amounts of our common stock in the public market after the existing legal and contractual restrictions lapse. This may adversely affect the prevailing market price and our ability to raise equity capital in the future. See “Risk Factors—Risks Related to this Offering and our Common Stock—Future sales, or the perception of future sales, by us or our existing stockholders in the public market following the completion of this offering could cause the market price for our common stock to decline.”

As of March 31, 2025, we had 172,963,709 shares of common stock outstanding. All shares sold in this offering will be freely tradable without registration under the Securities Act and without restriction, except for shares held by our “affiliates” ​(as defined under Rule 144). The shares of common stock held by certain stockholders including EQT, CPPIB, and Bain and certain of our directors, officers, and employees after this offering will be “restricted” securities under the meaning of Rule 144 and may not be sold in the absence of registration under the Securities Act, unless an exemption from registration is available, including the exemptions pursuant to Rule 144 under the Securities Act.

Pursuant to Rule 144, the restricted shares held by our affiliates will be available for sale in the public market at various times after the date of this prospectus following the expiration of the applicable lock-up period.

In addition, a total of 26,445,915 shares of our common stock has been reserved for issuance under (i) existing options awarded under our 2019 Stock Incentive Plan, (ii) our 2024 Equity Incentive Plan, and (iii) our 2024 Employee Stock Purchase Plan (each subject to adjustments for stock splits, stock dividends, and similar events), which equals approximately 15.3% of the shares of our common stock outstanding immediately following this offering. We have filed a registration statement on Form S-8 under the Securities Act to register common stock issued or reserved for issuance under (i) our 2019 Stock Incentive Plan, (ii) our 2024 Equity Incentive Plan, and (iii) our 2024 Employee Stock Purchase Plan, which statement automatically became effective upon filing. Accordingly, shares registered under such registration statement are available for sale in the open market, unless such shares are subject to vesting restrictions or the lock-up restrictions described below.

Rule 144

In general, under Rule 144, as currently in effect, a person (or persons whose shares are deemed aggregated) who is not deemed to be or have been one of our affiliates for purposes of the Securities Act at any time during 90 days preceding a sale and who has beneficially owned the shares proposed to be sold for at least six months, including the holding period of any prior owner other than an affiliate, is entitled to sell such shares without registration, subject to compliance with the public information requirements of Rule 144. If such a person has beneficially owned the shares proposed to be sold for at least one year, including the holding period of a prior owner other than an affiliate, then such person is entitled to sell such shares without complying with any of the requirements of Rule 144.

Under Rule 144, our affiliates or persons selling shares on behalf of our affiliates, who have met the six-month holding period for beneficial ownership of “restricted shares” of our common stock, are entitled to sell within any three-month period, a number of shares that does not exceed the greater of:

•

1% of the number of shares of our common stock then outstanding, which equals approximately 1,729,637 shares; or

​

 

41

•

the average reported weekly trading volume of our common stock on Nasdaq during the four calendar weeks preceding the filing of a notice on Form 144 with respect to such sale.

​

Sales under Rule 144 by our affiliates or persons selling shares on behalf of our affiliates are also subject to certain manner of sale provisions and notice requirements and to the availability of current public information about us. The sale of these shares, or the perception that sales will be made, could adversely affect the price of our common stock because a great supply of shares would be, or would be perceived to be, available for sale in the public market.

We are unable to estimate the number of shares that will be sold under Rule 144 since this will depend on the market price for our common stock, the personal circumstances of the stockholder and other factors.

Rule 701

In general, under Rule 701 of the Securities Act as currently in effect, any of our employees, consultants, or advisors who purchase shares from us in connection with a compensatory stock or option plan or other written agreement in a transaction that was completed in reliance on Rule 701, and complied with the requirements of Rule 701, is eligible to resell such shares in reliance on Rule 144, but without compliance with certain restrictions, including the holding period, contained in Rule 144.

Registration rights

For a description of rights that certain of our stockholders will have to require us to register the shares of our common stock they own, see “Certain Relationships and Related Transactions and Director Independence—Registration Rights Agreement” included in our Annual Report on Form 10-K for the fiscal year ended December 31, 2024 and incorporated by reference herein. Registration of these shares under the Securities Act would result in these shares becoming freely tradable immediately upon effectiveness of such registration.

Lock-up agreements

In connection with this offering, we, the selling stockholders and certain of our officers and directors have agreed with the underwriters, subject to certain exceptions, not to sell, dispose of or hedge any shares of our common stock or securities convertible into or exchangeable for shares of common stock during the period ending      days after the date of this prospectus (the “restricted period”) except with the prior written consent of J.P. Morgan Securities LLC and Goldman Sachs & Co. LLC.

CERTAIN UNITED STATES FEDERAL INCOME TAX CONSEQUENCES TO NON-U.S. HOLDERS

The following is a summary of certain United States federal income tax consequences to non-U.S. holders (as defined below) of the ownership and disposition of our common stock. Except where noted, this summary deals only with common stock that is held as a capital asset by a non-U.S. holder (as defined below).

A “non-U.S. holder” means a beneficial owner of our common stock (other than an entity or arrangement treated as a partnership for United States federal income tax purposes) that is not, for United States federal income tax purposes, any of the following:

•

an individual who is a citizen or resident of the United States;

​

•

a corporation (or any other entity treated as a corporation for United States federal income tax purposes) created or organized in or under the laws of the United States, any state thereof or the District of Columbia;

​

•

an estate the income of which is subject to United States federal income taxation regardless of its source; or

​

•

a trust if it (1) is subject to the primary supervision of a court within the United States and one or more “United States persons” ​(within the meaning of Section 7701(a)(30) of the Code) have the authority to control all substantial decisions of the trust or (2) has a valid election in effect under applicable United States Treasury regulations to be treated as a United States person.

​

This summary is based upon provisions of the Code, and United States Treasury regulations, rulings, judicial decisions, and administrative pronouncements, in each case as of the date hereof. Those authorities may be changed, perhaps retroactively, so as to result in United States federal income tax consequences different from those summarized below. This summary does not address all of the United States federal income tax considerations that may be relevant to you in light of your particular circumstances, nor does it address the Medicare tax on net investment income, the alternative minimum tax, United States federal estate and gift taxes or the effects of any state, local or non-United States tax laws. In addition, it does not represent a detailed description of the United States federal income tax consequences applicable to you if you are subject to special treatment under the United States federal income tax laws (including if you are a United States expatriate, foreign pension fund, “controlled foreign corporation,” “passive foreign investment company,” tax-exempt or governmental organization, brokers, dealer or trader in securities, bank, insurance company, or a partnership or other pass-through entity for United States federal income tax purposes (and investors therein)). We cannot assure you that a change in law will not alter significantly the tax considerations that we describe in this summary.

If a partnership (or other entity or arrangement treated as a partnership for United States federal income tax purposes) holds our common stock, the tax treatment of a partner will generally depend upon the status of the partner and the activities of the partnership. If you are a partner of a partnership considering an investment in our common stock, you should consult your tax advisors.

If you are considering the purchase of our common stock, you should consult your own tax advisors concerning the particular United States federal income tax consequences to you of the purchase, ownership, and disposition of our common stock, as well as the consequences to you arising under other United States federal tax laws and the laws of any other taxing jurisdiction.

Dividends

As described in the section entitled “Dividend Policy,” we do not anticipate declaring or paying dividends to holders of our common stock in the foreseeable future. However, in the event that we make a distribution of cash or other property (other than certain pro rata distributions of our stock) in respect of our common stock, the distribution generally will be treated as a dividend for United States federal income tax purposes to the extent it is paid from our current or accumulated earnings and profits, as determined under United States federal income tax principles. Any portion of a distribution that exceeds our current and accumulated earnings and profits generally will be treated first as a tax-free return of capital, causing a reduction in the adjusted tax basis of a non-U.S. holder’s common stock, and to the extent the amount of

 

43

CONFIDENTIAL TREATMENT REQUESTED

PURSUANT TO 17 C.F.R. SECTION 200.83

the distribution exceeds a non-U.S. holder’s adjusted tax basis in our common stock, the excess will be treated as gain from the disposition of our common stock (the tax treatment of which is discussed below under “—Gain on disposition of common stock”).

Dividends paid to a non-U.S. holder generally will be subject to withholding of United States federal income tax at a 30% rate or such lower rate as may be specified by an applicable income tax treaty. However, dividends that are effectively connected with the conduct of a trade or business by the non-U.S. holder within the United States (and, if required by an applicable income tax treaty, are attributable to a United States permanent establishment) are not subject to the withholding tax, provided certain certification and disclosure requirements are satisfied. To claim the exemption, the non-U.S. holder must furnish to the applicable withholding agent a valid IRS Form W-8ECI, certifying that the dividends are effectively connected with the non-U.S. holder’s conduct of a trade or business within the United States. Instead, such dividends are subject to United States federal income tax on a net income basis generally in the same manner as if the non-U.S. holder were a United States person as defined under the Code. Any such effectively connected dividends received by a foreign corporation may be subject to an additional “branch profits tax” at a 30% rate or such lower rate as may be specified by an applicable income tax treaty.

A non-U.S. holder who wishes to claim the benefit of an applicable income tax treaty rate and avoid backup withholding, as discussed below, for dividends will be required (1) to provide the applicable withholding agent with a properly executed IRS Form W-8BEN or Form W-8BEN-E (or other applicable form) certifying under penalty of perjury that such holder is not a United States person as defined under the Code and is eligible for treaty benefits or (2) if our common stock is held through certain foreign intermediaries, to satisfy the relevant certification requirements of applicable United States Treasury regulations. Special certification and other requirements apply to certain non-U.S. holders that are pass-through entities rather than corporations or individuals.

A non-U.S. holder eligible for a reduced rate of United States federal withholding tax pursuant to an applicable income tax treaty may obtain a refund of any excess amounts withheld by timely filing an appropriate claim for refund with the IRS.

Gain on disposition of common stock

Subject to the discussion of backup withholding and FATCA (as defined below) below, any gain realized by a non-U.S. holder on the sale or other disposition of our common stock generally will not be subject to United States federal income or withholding tax unless:

•

the gain is effectively connected with a trade or business of the non-U.S. holder in the United States (and, if required by an applicable income tax treaty, is attributable to a United States permanent establishment of the non-U.S. holder);

​

•

the non-U.S. holder is a nonresident alien individual who is present in the United States for 183 days or more in the taxable year of that disposition, and certain other conditions are met; or

​

•

we are or have been a “United States real property holding corporation” for United States federal income tax purposes at any time within the five-year period preceding the disposition or the non-U.S. holder’s holding period, whichever period is shorter, the non-U.S. holder is not eligible for a treaty exemption, and either (1) our common stock is not regularly traded on an established securities market during the calendar year in which the sale or disposition occurs or (2) the non-U.S. holder owned or is deemed to have owned at any time within the five-year period preceding the disposition or the non-U.S. holder’s holding period, whichever period is shorter, more than 5% of our common stock.

​

A non-U.S. holder described in the first bullet point immediately above will be subject to tax on the gain derived from the sale or other disposition in the same manner as if the non-U.S. holder were a United States person as defined under the Code. In addition, if any non-U.S. holder described in the first bullet point immediately above is a foreign corporation, the gain realized by such non-U.S. holder may be subject to an additional “branch profits tax” at a 30% rate or such lower rate as may be specified by an applicable income tax treaty. An individual non-U.S. holder described in the second bullet point immediately above will be subject to a 30% (or such lower rate as may be specified by an applicable income tax treaty) tax on the gain derived from the sale or other disposition, which gain may be offset by United States source capital losses even

PURSUANT TO 17 C.F.R. SECTION 200.83

though the individual is not considered a resident of the United States provided the non-U.S. holder has timely filed U.S. federal income tax returns with respect to such losses.

Generally, a corporation is a “United States real property holding corporation” if the fair market value of its United States real property interests equals or exceeds 50% of the sum of the fair market value of its worldwide real property interests and its other assets used or held for use in a trade or business (all as determined for United States federal income tax purposes). We believe we are not and do not anticipate becoming a “United States real property holding corporation” for United States federal income tax purposes.

Information reporting and backup withholding

Distributions paid to a non-U.S. holder and the amount of any tax withheld with respect to such distributions generally will be reported to the IRS. Copies of the information returns reporting such distributions and any withholding may also be made available to the tax authorities in the country in which the non-U.S. holder resides under the provisions of an applicable income tax treaty.

A non-U.S. holder will not be subject to backup withholding on distributions received if such holder certifies under penalty of perjury that it is a non-U.S. holder, such as by furnishing a valid IRS Form W-8BEN, W-8BEN-E, or W-8ECI (and the payor does not have actual knowledge or reason to know that such holder is a United States person as defined under the Code), or such holder otherwise establishes an exemption.

Information reporting and, depending on the circumstances, backup withholding will apply to the proceeds of a sale or other disposition of our common stock within the United States or conducted through certain United States-related financial intermediaries, unless the beneficial owner certifies under penalty of perjury that it is a non-U.S. holder (and the payor does not have actual knowledge or reason to know that the beneficial owner is a United States person as defined under the Code) or such owner otherwise establishes an exemption.

Backup withholding is not an additional tax and any amounts withheld under the backup withholding rules will be allowed as a refund or a credit against a non-U.S. holder’s United States federal income tax liability provided the required information is timely furnished to the IRS.

Additional withholding requirements

Under Sections 1471 through 1474 of the Code (such sections commonly referred to as “FATCA”), a 30% United States federal withholding tax may apply to any dividends paid on our common stock to (1) a “foreign financial institution” ​(as specifically defined in the Code and whether such foreign financial institution is the beneficial owner or an intermediary) which does not provide sufficient documentation, typically on IRS Form W-8BEN-E, evidencing either (x) an exemption from FATCA or (y) its compliance (or deemed compliance) with FATCA (which may alternatively be in the form of compliance with an intergovernmental agreement with the United States) in a manner which avoids withholding or (2) a “non-financial foreign entity” ​(as specifically defined in the Code and whether such non-financial foreign entity is the beneficial owner or an intermediary) which does not provide sufficient documentation, typically on IRS Form W-8BEN-E, evidencing either (x) an exemption from FATCA or (y) adequate information regarding certain substantial United States beneficial owners of such entity (if any). If a dividend payment is both subject to withholding under FATCA and subject to the withholding tax discussed above under “—Dividends,” an applicable withholding agent may credit the withholding under FATCA against, and therefore reduce, such other withholding tax. FATCA withholding may also apply to payments of gross proceeds of dispositions of our common stock, although under proposed United States Treasury regulations (the preamble to which specifies that taxpayers are permitted to rely on them pending finalization), no withholding will apply on payments of gross proceeds. You should consult your own tax advisors regarding these requirements and whether they may be relevant to your ownership and disposition of our common stock.

UNDERWRITING

The selling stockholders are offering the shares of common stock described in this prospectus through a number of underwriters. J.P. Morgan Securities LLC and Goldman Sachs & Co. LLC are acting as joint book-running managers of the offering and representatives of the underwriters. We and the selling stockholders have entered into an underwriting agreement with the underwriters. Subject to the terms and conditions of the underwriting agreement, the selling stockholders have agreed to sell to the underwriters, and each underwriter has severally agreed to purchase, at the public offering price less the underwriting discount set forth on the cover page of this prospectus, the number of shares of common stock listed next to its name in the following table:

The underwriters are committed to purchase all the shares of common stock offered by the selling stockholders if they purchase any shares. The underwriting agreement also provides that if an underwriter defaults, the purchase commitments of non-defaulting underwriters may also be increased or the offering may be terminated.

The underwriters propose to offer the shares of common stock directly to the public at the public offering price set forth on the cover page of this prospectus and to certain dealers at that price less a concession not in excess of $      per share. Any such dealers may resell shares to certain other brokers or dealers at a discount of up to $          per share from the public offering price. After the offering of the shares to the public, if all of the shares of common stock are not sold at the public offering price, the underwriters may change the offering price and the other selling terms. The offering of the shares by the underwriters is subject to receipt and acceptance and subject to the underwriters’ right to reject any order in whole or in part. Sales of any shares made outside of the United States may be made by affiliates of the underwriters.

The underwriters have an option to purchase up to            additional shares of common stock from the selling stockholders to cover sales of shares by the underwriters that exceed the number of shares specified in the table above. The underwriters have 30 days from the date of this prospectus to exercise this option to purchase additional shares. If any shares are purchased with this option to purchase additional shares, the underwriters will purchase shares in approximately the same proportion as shown in the table above. If any additional shares of common stock are purchased, the underwriters will offer the additional shares on the same terms as those on which the shares are being offered.

The underwriting fee is equal to the public offering price per share of common stock less the amount paid by the underwriters to the selling stockholders per share of common stock. The underwriting fee is $          per share. The following table shows the per share and total underwriting discount to be paid to the underwriters assuming both no exercise and full exercise of the underwriters’ option to purchase additional shares from the selling stockholders.

We estimate that the total expenses of this offering, including registration, filing and listing fees, printing fees, and legal and accounting expenses, but excluding the underwriting discount, will be

approximately $      . We have also agreed to reimburse the underwriters for certain of their expenses in an amount up to $      . The underwriters have agreed to reimburse us for a certain portion of the expenses in connection with this offering.

A prospectus in electronic format may be made available on the web sites maintained by one or more underwriters, or selling group members, if any, participating in the offering. The underwriters may agree to allocate a number of shares to underwriters and selling group members for sale to their online brokerage account holders. Internet distributions will be allocated by the representatives to underwriters and selling group members that may make Internet distributions on the same basis as other allocations.

We have agreed that we will not (i) offer, pledge, sell, contract to sell, sell any option or contract to purchase, purchase any option or contract to sell, grant any option, right, or warrant to purchase, lend or otherwise transfer or dispose of, directly or indirectly, or submit to, or file with, the SEC a registration statement under the Securities Act relating to, any shares of our common stock or securities convertible into or exercisable or exchangeable for any shares of our common stock, or publicly disclose the intention to undertake any of the foregoing, or (ii) enter into any swap or other agreement that transfers all or a portion of the economic consequences associated with the ownership of any shares of common stock or any such other securities (regardless of whether any of these transactions are to be settled by the delivery of shares of common stock or such other securities, in cash or otherwise), in each case, without the prior written consent of J.P. Morgan Securities LLC and Goldman Sachs & Co. LLC for a period of      days after the date of this prospectus, other than the shares of our common stock to be sold in this offering, subject to certain exceptions.

The restrictions on our actions, as described above, do not apply to certain transactions, including (i) any grants of options or other equity awards or issuances of shares of our common stock upon the exercise of options or other equity awards, in each case, granted under the terms of an equity compensation plan as described in this prospectus, (ii) any filing by us of a registration statement on Form S-8 relating to any equity compensation plan or arrangement described in this prospectus or any assumed benefit plan pursuant to an acquisition or similar strategic transaction, (iii) any shares of our common stock issued upon the exercise, conversion, or exchange of our securities outstanding as of the date of this prospectus and described in this prospectus, (iv) up to 5.0% of the total number of outstanding shares of our common stock issued by us in connection with mergers, acquisitions, or commercial or strategic transactions (including, without limitation, entry into joint ventures, marketing, or distribution agreements or collaboration agreements or acquisitions of technology, assets, or intellectual property licenses), and (v) confidential submission with the SEC or the Financial Industry Regulatory Authority, Inc. of any registration statement under the Securities Act; provided that in the case of clauses (iii) through (v), we shall cause each recipient that is a member of our board of directors, one of our executive officers, or a beneficial holder of 5.0% or more of our fully diluted capital stock to execute a lock-up agreement for the restricted period subject to the terms and conditions summarized herein, if not already a party thereto; provided, further, that in the case of clause (iv), we shall cause each recipient to execute a lock-up agreement for the restricted period.

Certain of our directors and executive officers and the selling stockholders (such persons, the “lock-up parties”) have entered into lock-up agreements with the underwriters prior to the commencement of this offering pursuant to which each lock-up party, with limited exceptions, for a period of      days after the date of this prospectus, may not (and may not cause any of their direct or indirect affiliates to), without the prior written consent of J.P. Morgan Securities LLC and Goldman Sachs & Co. LLC, (1) offer, pledge, sell, contract to sell, sell any option or contract to purchase, purchase any option or contract to sell, grant any option, right, or warrant to purchase, lend or otherwise transfer or dispose of, directly or indirectly, any shares of our common stock or any securities convertible into or exercisable or exchangeable for our common stock (including, without limitation, common stock or such other securities which may be deemed to be beneficially owned by such lock-up parties in accordance with the rules and regulations of the SEC and securities which may be issued upon exercise of a stock option or warrant (collectively with the common stock, the “lock-up securities”)), (2) enter into any hedging, swap, or other agreement or transaction that transfers, in whole or in part, any of the economic consequences of ownership of the lock-up securities, whether any such transaction described in clause (1) or (2) above is to be settled by delivery of lock-up securities, in cash or otherwise, (3) make any demand for, or exercise any right with respect to, the

Such persons or entities have further acknowledged that these undertakings preclude them from engaging in any hedging or other transactions or arrangements (including, without limitation, any short sale or the purchase or sale of, or entry into, any put or call option, or combination thereof, forward, swap or any other derivative transaction or instrument, however described or defined) designed, or intended, or which could reasonably be expected, to lead to or result in a sale, disposition or transfer (by any person or entity, whether or not a signatory to such agreement) of any economic consequences of ownership, in whole or in part, directly or indirectly, of any lock-up securities, whether any such transaction or arrangement (or instrument provided for thereunder) would be settled by delivery of lock-up securities, in cash or otherwise.

The restrictions described in the immediately preceding paragraph and contained in the lock-up agreements between the underwriters and the lock-up parties do not apply, subject in certain cases to various conditions, to certain transactions, including: (a) transfers of lock-up securities: (i) as bona fide gifts, or for bona fide estate planning purposes; (ii) by will or intestacy; (iii) to any trust for the direct or indirect benefit of the lock-up party or any immediate family member; (iv) to any immediate family member of the lock-up party; (v) to a nominee or custodian of a person or entity to whom a disposition or transfer would be permissible under clauses (i) through (iv); (vi) by operation of law; (vii) to us from a current or former employee of ours upon death, disability, or termination of employment of such employee or to us pursuant to any contractual arrangement that provides us with a right to purchase lock-up securities; (viii) if the lock-up party is not a natural person, to any (1) corporation, partnership, limited liability company, trust or other entity, in each case, that controls, or is controlled by or is under common control with, the lock-up party or its immediate family, or is otherwise a direct or indirect affiliate (as defined in Rule 405 promulgated under the Securities Act) of the lock-up party, or (2) investment fund or other entity controlling, controlled by, managing or managed by or under common control with the lock-up party or its affiliates or as part of a distribution, transfer or disposition by the lock-up party to its stockholders, partners, members or other equity holders; (ix) as part of a sale of lock-up securities acquired in open-market transactions after the completion of this offering; (x) to us in connection with the vesting, settlement or exercise of restricted stock units, options, warrants or other rights to purchase shares of our common stock (including “net” or “cashless” exercise), including for the payment of exercise price and tax and remittance payments; (xi) pursuant to a bona fide third-party tender offer, merger, consolidation or other similar transaction approved by our board of directors and made to all stockholders involving a change in control in which the acquiring party or “group” ​(within the meaning of Section 13(d)(3) of the Exchange Act) of persons becomes the beneficial owner of more than 50% of the total voting power of the voting stock of us following such transaction; provided that if such transaction is not completed, all such lock-up securities would remain subject to the restrictions in the immediately preceding paragraph; (xii) in connection with any reclassification or conversion of our common stock; (xiii) to the lock-up party’s direct or indirect general partner or managing member or to certain officers, partners, or members thereof in connection with such general partner’s, managing member’s, officers’, partners’ or members’ donation to charitable organizations, educational institutions, family foundations or donor advised funds at sponsoring organizations; (xiv) in connection with the sales of shares of common stock pursuant to a trading plan under Rule 10b5-1 of the Exchange Act; (xv) the sale of shares of common stock to the underwriters pursuant to the underwriting agreement; or (xvi) for Institutional Investors only, pursuant to the pledge, hypothecation or other granting of a security interest in lock-up securities to one or more lending institutions as collateral or security for any loan, advance or extension of credit and any transfer upon foreclosure upon such securities; provided, that (unless entered into prior to the execution of the lock-up agreement) prior to entering into the collateral agreement or similar agreement in connection with the loan, advance or extension of credit, each pledgee shall enter into a lock-up agreement to take effect in the event that the pledgee takes possession of such lock-up party’s lock-up securities as a result of a foreclosure, margin call or similar disposition; provided further, that the lock-up party shall provide each of J.P. Morgan Securities LLC and Goldman Sachs & Co. LLC with prior written notice informing them of any public filing, report or announcement with respect to such pledge, hypothecation or other grant of a security interest or foreclosure; provided further that for any pledge, hypothecation, granting of security entered into after the execution of the lock-up agreement, the aggregate amount of lock-up securities pledged as collateral pursuant to this clause (together with any shares pledged prior to the execution of the lock-up agreement) during the restricted period shall not exceed 10% of the total number of shares of common stock beneficially owned by the applicable lock-up party; (b) exercise of the options, settlement of RSUs or other equity awards, or the exercise of warrants, granted

pursuant to plans described in this prospectus; provided that any lock-up securities received upon such exercise, vesting or settlement would be subject to restrictions similar to those in the immediately preceding paragraph; and (c) the establishment by lock-up parties of trading plans under Rule 10b5-1 under the Exchange Act; provided that such plan does not provide for the transfer of lock-up securities during the restricted period.

J.P. Morgan Securities LLC and Goldman Sachs & Co. LLC, in their sole discretion, may release the securities subject to any of the lock-up agreements with the underwriters described above, in whole or in part at any time.

We have agreed to indemnify the underwriters against certain liabilities, including liabilities under the Securities Act.

Our common stock is listed on Nasdaq under the symbol “WAY.”

In connection with this offering, the underwriters may engage in stabilizing transactions, which involves making bids for, purchasing, and selling shares of common stock in the open market for the purpose of preventing or retarding a decline in the market price of the common stock while this offering is in progress. These stabilizing transactions may include making short sales of common stock, which involves the sale by the underwriters of a greater number of shares of common stock than they are required to purchase in this offering, and purchasing shares of common stock on the open market to cover positions created by short sales. Short sales may be “covered” shorts, which are short positions in an amount not greater than the underwriters’ option to purchase additional shares referred to above, or may be “naked” shorts, which are short positions in excess of that amount. The underwriters may close out any covered short position either by exercising their option to purchase additional shares, in whole or in part, or by purchasing shares in the open market. In making this determination, the underwriters will consider, among other things, the price of shares available for purchase in the open market compared to the price at which the underwriters may purchase shares through the option to purchase additional shares. A naked short position is more likely to be created if the underwriters are concerned that there may be downward pressure on the price of the common stock in the open market that could adversely affect investors who purchase in this offering. To the extent that the underwriters create a naked short position, they will purchase shares in the open market to cover the position.

The underwriters have advised us that, pursuant to Regulation M of the Securities Act, they may also engage in other activities that stabilize, maintain, or otherwise affect the price of the common stock, including the imposition of penalty bids. This means that if the representatives of the underwriters purchase common stock in the open market in stabilizing transactions or to cover short sales, the representatives can require the underwriters that sold those shares as part of this offering to repay the underwriting discount received by them.

These activities may have the effect of raising or maintaining the market price of the common stock or preventing or retarding a decline in the market price of the common stock, and, as a result, the price of the common stock may be higher than the price that otherwise might exist in the open market. If the underwriters commence these activities, they may discontinue them at any time. The underwriters may carry out these transactions on Nasdaq, in the over-the-counter market or otherwise.

Other than in the United States, no action has been taken by us or the underwriters that would permit a public offering of the securities offered by this prospectus in any jurisdiction where action for that purpose is required. The securities offered by this prospectus may not be offered or sold, directly or indirectly, nor may this prospectus or any other offering material or advertisements in connection with the offer and sale of any such securities be distributed or published in any jurisdiction, except under circumstances that will result in compliance with the applicable rules and regulations of that jurisdiction. Persons into whose possession this prospectus comes are advised to inform themselves about and to observe any restrictions relating to the offering and the distribution of this prospectus. This prospectus does not constitute an offer to sell or a solicitation of an offer to buy any securities offered by this prospectus in any jurisdiction in which such an offer or a solicitation is unlawful.

Certain of the underwriters and their affiliates have provided in the past to us and our affiliates and may provide from time to time in the future certain commercial banking, financial advisory, investment

banking, and other services for us and such affiliates in the ordinary course of their business, for which they have received and may continue to receive customary fees and commissions. In addition, from time to time, certain of the underwriters and their affiliates may effect transactions for their own account or the account of customers, and hold on behalf of themselves or their customers, long or short positions in our debt or equity securities or loans, and may do so in the future. Certain of the underwriters and/or certain of their affiliates are lenders and/or agents under the Credit Facilities, and accordingly, are entitled to fees and expenses in connection therewith.

Item 14.   Indemnification of directors and officers

Section 102(b)(7) of the Delaware General Corporation Law (the “DGCL”) allows a corporation to provide in its certificate of incorporation that a director of the corporation will not be personally liable to the corporation or its stockholders for monetary damages for breach of fiduciary duty as a director, except where the director breached the duty of loyalty, failed to act in good faith, engaged in intentional misconduct or knowingly violated a law, authorized the payment of a dividend, or approved a stock repurchase in violation of Delaware corporate law or obtained an improper personal benefit. Our amended and restated certificate of incorporation provides for this limitation of liability.

Section 145 of the DGCL (“Section 145”) provides, among other things, that a Delaware corporation may indemnify any person who was, is or is threatened to be made, party to any threatened, pending or completed action, suit, or proceeding, whether civil, criminal, administrative, or investigative (other than an action by or in the right of such corporation), by reason of the fact that such person is or was an officer, director, employee, or agent of such corporation or is or was serving at the request of such corporation as a director, officer, employee, or agent of another corporation or enterprise. The indemnity may include expenses (including attorneys’ fees), judgments, fines, and amounts paid in settlement actually and reasonably incurred by such person in connection with such action, suit or proceeding, provided such person acted in good faith, and in a manner he or she reasonably believed to be in or not opposed to the corporation’s best interests and, with respect to any criminal action or proceeding, had no reasonable cause to believe that his or her conduct was unlawful. A Delaware corporation may indemnify any persons who were or are a party to any threatened, pending or completed action or suit by or in the right of the corporation by reason of the fact that such person is or was a director, officer, employee, or agent of another corporation or enterprise. The indemnity may include expenses (including attorneys’ fees) actually and reasonably incurred by such person in connection with the defense or settlement of such action or suit, provided such person acted in good faith, and in a manner he or she reasonably believed to be in or not opposed to the corporation’s best interests, provided further that no indemnification is permitted without judicial approval if the officer, director, employee, or agent is adjudged to be liable to the corporation. Where an officer or director is successful on the merits or otherwise in the defense of any action referred to above, the corporation must indemnify him or her against the expenses (including attorneys’ fees) which such officer or director has actually and reasonably incurred.

PURSUANT TO 17 C.F.R. SECTION 200.83

Section 145 further authorizes a corporation to purchase and maintain insurance on behalf of any person who is or was a director, officer, employee, or agent of the corporation or is or was serving at the request of the corporation as a director, officer, employee, or agent of another corporation or enterprise, against any liability asserted against such person and incurred by such person in any such capacity, or arising out of his or her status as such, whether or not the corporation would otherwise have the power to indemnify such person under Section 145.

Our amended and restated bylaws provide that we must indemnify, and advance expenses to, our directors and officers to the full extent authorized by the DGCL. We have also entered into indemnification agreements with our directors, which agreements require us to indemnify these individuals to the fullest extent permitted under Delaware law against liabilities that may arise by reason of their service to us, and to advance expenses incurred as a result of any proceeding against them as to which they could be indemnified.

The indemnification rights set forth above shall not be exclusive of any other right which an indemnified person may have or hereafter acquire under any statute, provision of our amended and restated certificate of incorporation, our amended and restated bylaws, agreement, vote of stockholders, or disinterested directors or otherwise. Notwithstanding the foregoing, we shall not be obligated to indemnify a director or officer in respect of a proceeding (or part thereof) instituted by such director or officer, unless such proceeding (or part thereof) has been authorized by our board of directors pursuant to the applicable procedure outlined in the amended and restated bylaws.

Section 174 of the DGCL provides, among other things, that a director, who willfully or negligently approves of an unlawful payment of dividends or an unlawful stock purchase or redemption, may be held jointly and severally liable for such actions. A director who was either absent when the unlawful actions were approved or dissented at the time may avoid liability by causing his or her dissent to such actions to be entered in the books containing the minutes of the meetings of the board of directors at the time such action occurred or immediately after such absent director receives notice of the unlawful acts.

We maintain standard policies of insurance that provide coverage (1) to our directors and officers against loss rising from claims made by reason of breach of duty or other wrongful act and (2) to us with respect to indemnification payments that we may make to such directors and officers.

The underwriting agreement will provide for indemnification by the underwriters of us and our officers and directors, and by us of the underwriters, for certain liabilities arising under the Securities Act or otherwise in connection with this offering.

Insofar as indemnification for liabilities arising under the Securities Act may be permitted to directors, officers or persons controlling us under any of the foregoing provisions, in the opinion of the SEC, such indemnification is against public policy as expressed in the Securities Act and is therefore unenforceable.

Item 15.   Recent sales of securities

Since January 1, 2022, the Registrant has granted or issued the following securities of the Registrant which were not registered under the Securities Act:

•

An aggregate of 5,366,768 stock options to employees, directors, and consultants under the Registrant’s 2019 Stock Incentive Plan and 2024 Equity Incentive Plan, with per share exercise prices ranging from $21.50 to $39.67.

​

•

An aggregate of 1,376,139 shares of common stock that were not registered under the Securities Act to employees, directors, or consultants under our 2019 Stock Incentive Plan upon the exercise of vested stock options with per share exercise prices ranging from $4.14 to $37.20.

​

None of the foregoing transactions involved any underwriters, underwriting discounts or commissions, or any public offering. Unless otherwise stated, the sales of the above securities were deemed to be exempt from registration under the Securities Act in reliance upon Section 4(a)(2) of the Securities Act (or Regulation D or Regulation S promulgated thereunder) or Rule 701 promulgated under Section 3(b) of the Securities Act as transactions by an issuer not involving any public offering or pursuant to benefit plans and contracts relating to compensation as provided under Rule 701. The recipients of the securities in each of these transactions represented their intentions to acquire the securities for investment only and not with a

Item 17.   Undertakings

(1)   Insofar as indemnification for liabilities arising under the Securities Act may be permitted to directors, officers, and controlling persons of the Registrant pursuant to the foregoing provisions, or otherwise, the Registrant has been advised that in the opinion of the Securities and Exchange Commission such indemnification is against public policy as expressed in the Securities Act and is, therefore, unenforceable. In the event that a claim for indemnification against such liabilities (other than the payment by the registrant of expenses incurred or paid by a director, officer, or controlling person of the registrant in the successful defense of any action, suit, or proceeding) is asserted by such director, officer or controlling person in connection with the securities being registered, the Registrant will, unless in the opinion of its counsel the matter has been settled by controlling precedent, submit to a court of appropriate jurisdiction the question of whether such indemnification by it is against public policy as expressed in the Securities Act and will be governed by the final adjudication of such issue.

(2)   The undersigned Registrant hereby undertakes that:

(A)   For purposes of determining any liability under the Securities Act, the information omitted from the form of prospectus filed as part of this registration statement in reliance upon Rule 430A and contained in a form of prospectus filed by the Registrant pursuant to Rule 424(b) (1) or (4) or 497(h) under the Securities Act shall be deemed to be part of this registration statement as of the time it was declared effective.

(B)   For the purpose of determining any liability under the Securities Act, each post-effective amendment that contains a form of prospectus shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof.

(3)   The undersigned Registrant hereby undertakes to provide to the underwriters at the closing specified in the underwriting agreement certificates in such denominations and registered in such names as required by the underwriters to permit prompt delivery to each purchaser.
