Introductory Note

This Current Report on Form 8-K is being filed in connection with the consummation on March 17, 2026 (the “Closing Date”) of the transaction contemplated by that certain Agreement and Plan of Merger, dated December 7, 2025 (the “Merger Agreement”), by and among International Business Machines Corporation, a New York corporation (“IBM”), Corvo Merger Sub, Inc., a Delaware corporation and a wholly owned subsidiary of IBM (“Sub”), and Confluent, Inc., a Delaware corporation (“Confluent”).

On the Closing Date, pursuant to the Merger Agreement, Sub merged with and into Confluent (the “Merger”), with Confluent surviving the Merger as a wholly owned subsidiary of IBM (the “Surviving Corporation”).

Pursuant to the Merger Agreement, at the effective time of the Merger (the “Effective Time”), which time occurred on the Closing Date, each share of Confluent’s Class A common stock (the “Class A Common Stock”) and Class B common stock (the “Class B Common Stock” and, together with the Class A Common Stock, the “Common Stock”) issued and outstanding immediately prior to the Effective Time (subject to certain customary exceptions specified in the Merger Agreement) was automatically canceled and converted into the right to receive $31.00 in cash, without interest (the “Per Share Price”), subject to applicable withholding taxes.

The information set forth in the Introductory Note of this Current Report on Form 8-K is incorporated by reference into this Item 1.01.

On the Closing Date, Confluent and U.S. Bank Trust Company, National Association (as successor in interest to U.S. Bank National Association), as trustee (the “Trustee”), entered into the First Supplemental Indenture, dated as of the Closing Date (the “First Supplemental Indenture”), to the Indenture, dated as of December 13, 2021, by and between Confluent and the Trustee (the “Original Indenture” and, together with the First Supplemental Indenture, the “Indenture”), relating to Confluent’s 0% Convertible Senior Notes due 2027 (the “Notes”). As of the Closing Date, $1,100,000,000 aggregate principal amount of the Notes were outstanding.

As a result of the Merger, and pursuant to the First Supplemental Indenture, at and after the Effective Time, the right to convert each $1,000 principal amount of Notes was changed to a right to convert such principal amount of Notes into solely a number of units of Reference Property (as defined in the Indenture) in an aggregate amount equal to the conversion rate of the Notes in effect on the relevant conversion date (subject to any adjustments pursuant to the terms of the Indenture), with each unit of Reference Property consisting of $31.00 in cash, which is equal to the Per Share Price.

The consummation of the Merger constitutes a Fundamental Change, a Make-Whole Fundamental Change and a Share Exchange Event (each as defined in the Indenture) under the Indenture. The effective date of the Share Exchange Event, Fundamental Change and Make-Whole Fundamental Change in respect of the Notes is March 17, 2026, which is the Closing Date.

As a result of the Fundamental Change, each holder of the Notes will have the right to require Confluent to repurchase its Notes pursuant to the terms and procedures set forth in the Indenture on the fundamental change repurchase date for a cash repurchase price equal to 100% of the principal amount thereof, plus any accrued and unpaid special interest thereon to, but excluding, the fundamental change repurchase date.

The foregoing descriptions of the Indenture and the transactions contemplated thereby are subject to and qualified in their entirety by reference to the full text of the Indenture. A copy of the Original Indenture was filed as Exhibit 4.1 to the Current Report on Form 8-K filed by Confluent with the Securities and Exchange Commission (the “SEC”) on December 14, 2021. A copy of the First Supplemental Indenture is filed as Exhibit 4.1 hereto. The Original Indenture and the First Supplemental Indenture are incorporated by reference into this Item 1.01.  This Current Report on Form 8-K does not constitute an offer to tender for, or purchase, or a solicitation of an offer to tender for, or purchase, any of the Notes or any other security.

Following the effectiveness of the Form 25, the Surviving Corporation intends to file with the SEC a certification and notice of termination on Form 15 to terminate the registration of the Class A Common Stock under Section 12(g) of the Exchange Act and suspend Confluent’s reporting obligations under Section 13 and Section 15(d) of the Exchange Act with respect to the Class A Common Stock.
