In addition, Couchbase has agreed that, subject to certain exceptions, the Board will not withdraw its recommendation that Couchbase’s stockholders vote to adopt the Merger Agreement and approve the Merger.

Parent may terminate the Merger Agreement in certain additional limited circumstances, including if the Board withdraws its recommendation that Couchbase’s stockholders vote to adopt the Merger Agreement.

~~The~~Upon ~~Company~~termination of the Merger Agreement under specified circumstances, Couchbase will be required to pay Parent a termination fee of $42,000,000. Specifically, this termination fee is payable by Couchbase to Parent if the Merger Agreement is terminated by (1) Parent following the Board’s ~~stockholders~~determination ~~approved,~~to onchange its recommendation with respect to the Merger; or (2) Couchbase following the decision by the Board to authorize the acceptance of a ~~non~~Superior Proposal in accordance with the terms of the Merger Agreement (provided, that the termination fee will be $21,000,000 if (x) prior to the No-~~binding~~Shop ~~advisory~~Period ~~basis~~Start Date, ~~“One~~Couchbase ~~Year”~~terminates asthe Merger Agreement to enter into a definitive agreement with respect to a Superior Proposal, or (y) after the ~~preferred~~No-Shop ~~frequency~~Period Start Date, Couchbase terminates the Merger Agreement to enter into a definitive agreement with respect to a Superior Proposal in respect of ~~future~~which ~~advisory~~Couchbase ~~non~~has delivered the notice to Parent prior to the No-~~binding~~Shop ~~votes~~Period Start Date in accordance with the Merger Agreement).

Upon termination of the Merger Agreement under specified circumstances, Parent will be required to pay the Company a termination fee of $82,500,000. Specifically, this termination fee is payable by Parent to Couchbase if the Merger Agreement is terminated by (1) the Company’s termination of the Merger Agreement if Parent fails to timely consummate the Merger after the satisfaction or waiver of certain closing conditions and the Company stands ready to consummate the Closing; and (2) the Company’s termination of the Merger Agreement if Parent breaches its representations, warranties or covenants under the Merger Agreement such that there is a failure of certain conditions to the Merger that is not timely cured.

The Merger Agreement also provides that Couchbase, on one hand, or Parent and Merger Sub, on the other hand, may specifically enforce the obligations under the Merger Agreement, including the obligation to consummate the Merger if the conditions set forth in the Merger Agreement are satisfied.

Parent’s and Merger Sub’s aggregate liability for monetary damages for breaches of the Merger Agreement are capped at $82,500,000 plus certain reimbursement obligations and certain enforcement expenses, and Couchbase’s liability for monetary damages for breaches of the Merger Agreement are capped at $42,000,000 plus certain enforcement expenses, in each case subject to limited exceptions set forth in the Merger Agreement.

Pursuant to equity commitment letter, dated June 20, 2025 (the “Equity Commitment Letter”), investment funds managed by Haveli (the “Buyer Funds”) committed to provide Parent, at the consummation of the Merger, with an equity contribution to pay the cash amounts set forth therein for the purpose of funding up to the full amount of the aggregate merger consideration payable and all related fees and expenses related to the Merger, subject to the terms and conditions of the Equity Commitment Letter. Couchbase is a third party beneficiary of the Equity Commitment Letter and is entitled to enforce the investment commitment, on the terms and subject to the conditions set forth therein. In addition, the Buyer Funds have entered into limited guarantees with Couchbase, pursuant to which the Buyer Funds have guaranteed the obligations of Parent and Merger Sub to pay the termination fee payable by Parent in the event such termination fee becomes payable and certain reimbursement obligations under the Merger Agreement, on the terms and subject to the conditions set forth therein.

The foregoing description of the Merger Agreement is qualified in its entirety by reference to the full text of the Merger Agreement, a copy of which is filed as Exhibit 2.1 hereto and is incorporated into this report by reference. A copy of the Merger Agreement has been included to provide Couchbase’s stockholders and other security holders with information regarding its terms and is not intended to provide any factual information about Couchbase, Parent, Merger Sub or their respective affiliates. The representations, warranties and covenants contained in the Merger Agreement have been made solely for the purposes of the Merger Agreement and as of specific dates; were made solely for the benefit of the parties to the Merger Agreement; are not intended as statements of fact to be relied upon by Couchbase’s stockholders or other security holders, but rather as a way of allocating the risk between the parties in the event the statements therein prove to be inaccurate; have been modified or qualified by certain confidential disclosures that were made between the parties in connection with the negotiation of the Merger Agreement, which disclosures are not reflected in the Merger Agreement itself; may no longer be true as of a given date; and may apply standards of materiality in a way that is different from what may be viewed as material by Couchbase’s stockholders or other security holders. Couchbase’s stockholders and other security holders should not rely on the representations, warranties and covenants or any descriptions thereof as characterizations of the actual state of facts or condition of Couchbase, Parent, Merger Sub or their respective affiliates. Moreover, information concerning the subject matter of the representations and warranties may change after the date of the Merger Agreement, which subsequent information may or may not be fully reflected in Couchbase’s public disclosures. Couchbase acknowledges that, notwithstanding the inclusion of the foregoing cautionary statements, it is responsible for considering whether additional specific disclosures of material information regarding material contractual provisions are required to make the statements in this Form 8-K not misleading. The Merger Agreement should not be read alone but should instead be read in conjunction with the other information regarding the Merger Agreement, the Merger, Couchbase, Parent, Merger Sub, their respective affiliates and their respective businesses, that will be contained in, or incorporated by reference into, the Transaction Proxy Statement (as defined below) that Couchbase will file, as well as in the Forms 10-K, Forms 10-Q, Forms 8-K and other filings that Couchbase has made or will make with the SEC.

Voting Agreement

Also on June 20, 2025, in connection with the execution of the Merger Agreement, certain stockholders of Couchbase entered into voting agreements (the “Voting Agreements”) with the Company. These stockholders represent approximately 30 percent of Couchbase’s outstanding voting power. Under the Voting Agreements, the stockholders party thereto have agreed to vote their shares of Common Stock in favor of the adoption of the Merger Agreement and certain other matters. The Voting Agreements terminate in certain circumstances, including upon the valid termination of the Merger Agreement in accordance with its terms. The Voting Agreements also contain restrictions on transfer of shares of Common Stock held by the stockholders party thereto, subject to certain exceptions.

The foregoing description of the Voting Agreements is qualified in its entirety by reference to the full text of the forms of the Voting Agreements, copies of which are filed as Exhibit 10.1 and Exhibit 10.2 and are incorporated into this report by reference.

Additional Information and Where to Find It

Couchbase, the members of the Board and certain of Couchbase’s executive officers are participants in the solicitation of proxies from stockholders in connection with the Merger. Couchbase plans to file a proxy statement (the “Transaction Proxy Statement”) with the SEC in connection with the solicitation of proxies to approve the Merger. Matthew M. Cain, Alvina Y. Antar, Edward T. Anderson, Carol W. Carpenter, Lynn M. Christensen, Kevin J. Efrusy, Jeff Epstein, Aleksander J. Migon, David C. Scott and Richard A. Simonson, all of whom are members of Couchbase’s board of directors, and Margaret Chow, SVP, Chief Legal Officer and Corp. Secretary, William R. Carey, Vice President, Interim Chief Financial Officer and Chief Accounting Officer, and Huw Owen, SVP and Chief Revenue Officer, are participants in Couchbase’s solicitation.

Information regarding such participants, including their direct or indirect interests, by security holdings or otherwise, will be included in the Transaction Proxy Statement and other relevant documents to be filed with the SEC in connection with the Merger. Additional information about such participants is available under the captions “Board of Directors and Corporate Governance,” “Executive Officers” and “Security Ownership of Certain Beneficial Owners and Management” in Couchbase’s definitive proxy statement in connection with its 2025 Annual Meeting of Stockholders (the “2025 Proxy Statement”), which was filed with the SEC on April 16, 2025 (and is available at https://www.sec.gov/ix?doc=/Archives/edgar/data/0001845022/000184502225000036/base-20250416.htm). To the extent that holdings of Couchbase’s securities have changed since the amounts printed in the 2025 Proxy Statement, such changes have been or will be reflected on Statements of Change in Ownership on Form 4 filed with the SEC (which are available at https://www.sec.gov/cgi-bin/browse-edgar?action=getcompany&CIK=1845022&type=&dateb=&owner=only&count=40&search_text=). Information regarding Couchbase’s transactions with related persons is set forth under the caption “Related Person Transactions” in the 2025 Proxy Statement. Certain illustrative information regarding the payments to that may be owed, and the circumstances in which they may be owed, to Couchbase’s named executive officers in a change of control of Couchbase is set forth under the caption “Executive Compensation-Potential Payments upon Termination or Change in Control” in the 2025 Proxy Statement.

Promptly after filing the definitive Transaction Proxy Statement with the SEC, Couchbase will mail the definitive Transaction Proxy Statement and a WHITE proxy card to each stockholder entitled to vote at the special meeting to consider the adoption of the Merger Agreement. STOCKHOLDERS ARE URGED TO READ THE TRANSACTION PROXY STATEMENT (INCLUDING ANY AMENDMENTS OR SUPPLEMENTS THERETO) AND ANY OTHER RELEVANT DOCUMENTS THAT COUCHBASE WILL FILE WITH THE SEC WHEN THEY BECOME AVAILABLE BECAUSE THEY WILL CONTAIN IMPORTANT INFORMATION. Stockholders may obtain, free of charge, the preliminary and definitive versions of the Transaction Proxy Statement, any amendments or supplements thereto, and any other relevant documents filed by Couchbase with the SEC in connection with the Merger at the SEC’s website (http://www.sec.gov). Copies of Couchbase’s Transaction Proxy Statement, any amendments or supplements thereto, and any other relevant documents filed by Couchbase with the SEC in connection with the Merger will also be available, free of charge, at Couchbase’s investor relations website (https://investor.couchbase.com), or by emailing Couchbase’s investor relations department (ir@couchbase.com).
