Item 1.01 Entry into a Material Definitive Agreement.

Merger Agreement

On November 18, 2025, Semrush Holdings, Inc., a Delaware corporation (the “Company”), entered into an Agreement and Plan of Merger (the “Merger Agreement”) by and among the Company, Adobe Inc., a Delaware corporation (“Adobe”), and Fenway Merger Sub, Inc., a Delaware corporation and a wholly owned subsidiary of Adobe (“Merger Sub”). Pursuant to the Merger Agreement, and upon the terms and subject to the conditions therein, Merger Sub will merge with and into the Company (the “Merger”), with the Company surviving the Merger as a wholly owned subsidiary of Adobe.

Subject to the terms and conditions of the Merger Agreement, at the effective time of the Merger (the “Effective Time”), each share of Class A common stock, par value $0.00001 per share, of the Company (“Class A Common Stock”) and each share of Class B common stock, par value $0.00001 per share, of the Company (the “Class B Common Stock” and, together with the Class A Common Stock, the “Company Common Stock”), in each case, issued and outstanding immediately prior to the Effective Time, subject to certain limitations, will be converted into the right to receive $12.00 in cash, without interest (the “Merger Consideration”).

Treatment of Company Equity Awards

At the Effective Time, outstanding equity awards of the Company will generally be treated as follows:

Options. Each vested option to purchase shares of Company Common Stock (“Option”) and each Option held by a non-employee director or certain contractors or service providers (each, a “Specified Individual”) will be cancelled and cashed out for a payment equal to the excess of the Merger Consideration over the exercise price of such Option in respect of each underlying share. Otherwise, each unvested in-the-money Option will be assumed and converted into a restricted stock unit award relating to Adobe common stock (an “Adobe RSU Award”), based on the spread value of the Option and the closing price per share of Adobe common stock over the 30 consecutive calendar days ending on (and including) the second to last calendar day preceding the closing date (“Adobe Trading Price”), with no less favorable vesting terms. Options with an exercise price equal to or greater than the Merger Consideration will be cancelled for no consideration.

RSU Awards. Each restricted stock unit award relating to shares of Company Common Stock that was subject solely to service-based vesting requirements as of the grant date (“RSU Award”) held by a Specified Individual will be cancelled and cashed out for a payment equal to the Merger Consideration in respect of each underlying share. Each other RSU Award will be assumed and converted into an Adobe RSU Award representing equivalent value based on the Adobe Trading Price, with no less favorable vesting terms.

PSU Awards. Each restricted stock unit award relating to shares of Company Common Stock that is subject to performance-based vesting requirements (“PSU Award”) that becomes vested at the Effective Time in accordance with the terms of the applicable award agreement will be cancelled and cashed out for a payment equal to the Merger Consideration in respect of each underlying share (with achievement of applicable performance metrics determined based on actual performance in accordance with the terms of the applicable award agreement), and the portion of the award that does not become vested at the Effective Time in accordance with the terms of the applicable award agreement will be forfeited for no consideration. Each other outstanding PSU Award will be assumed and converted into an Adobe RSU Award (with applicable performance goals deemed achieved based on actual performance through the latest practicable date prior to the Closing Date) representing equivalent value based on the Adobe Trading Price, with no less favorable service-based vesting terms.

RS Awards. The restricted stock award relating to shares of Company Common Stock will be assumed and converted into a restricted stock award of Adobe representing equivalent value based on the Adobe Trading Price, with no less favorable vesting terms.

Closing Conditions

Under the terms of the Merger Agreement, the completion of the Merger is subject to certain customary closing conditions, including, among others: (i) the approval of the Merger Agreement and the Merger by the affirmative vote (in person or by proxy) of the holders of a majority of the voting power of the outstanding Company Common Stock entitled to vote thereon voting as a single class (the “Company Stockholder Approval”); (ii) the accuracy of the parties’ respective representations and warranties in the Merger Agreement, subject to specified materiality qualifications; (iii) compliance by the parties with their respective covenants in the Merger Agreement in all material respects; (iv) the absence of any law or order restraining, enjoining, or otherwise prohibiting the consummation of the Merger; (v) the expiration of the waiting period applicable to the Merger under the Hart-Scott-Rodino Antitrust Improvements Act of 1976, as amended, and receipt of other approvals under specified antitrust and foreign investment laws; and (vi) the absence of a Company Material Adverse Effect (as defined in the Merger Agreement) on or after the date of the Merger Agreement that is continuing as of immediately prior to the closing.

Board Approval of the Merger Agreement

The Merger Agreement and the consummation of the transactions contemplated thereby have been unanimously approved by the Company Board of Directors and the Company Board of Directors has resolved to recommend to the stockholders of the Company to approve the Merger Agreement and the transactions contemplated by the Merger Agreement, including the Merger.

Representations, Warranties and Covenants

The Merger Agreement contains customary representations, warranties and covenants made by each of the Company, Adobe and Merger Sub, including, among others, covenants by the Company regarding the conduct of its business during the pendency of the transactions contemplated by the Merger Agreement, public disclosures and other matters. The Company is required, among other things, not to solicit alternative business combination transactions and, subject to certain exceptions, not to engage in discussions or negotiations regarding an alternative business combination transaction.

Termination Rights, Termination Fee

Both the Company and Adobe may terminate the Merger Agreement under certain specified circumstances, including, among others, (i) if the Merger is not consummated by August 18, 2026, subject to an extension to November 18, 2026, in order to obtain required regulatory approvals, (ii) if the Company Stockholder Approval is not obtained at the Company’s stockholders meeting to approve the Merger and the Merger Agreement, (iii) in the case of Adobe, if the Company materially breaches its covenants not to solicit alternative business combination transactions or the Company’s Board of Directors effects a change of recommendation with respect to the proposed transaction or (iv) in the case of the Company, in order to enter into a definitive agreement with respect to a “superior proposal” subject to certain requirements. In certain circumstances in connection with the termination of the Merger Agreement, including if the Company materially breaches its covenants not to solicit alternative business combination transactions, the Company’s Board of Directors effects a change of recommendation, or the Company terminates the Merger Agreement to enter into a definitive agreement with respect to a “superior proposal,” the Company would be required to pay Adobe a termination fee of $63,000,000 in cash.

The foregoing description of the Merger Agreement does not purport to be complete and is qualified in its entirety by the full text of the Merger Agreement, a copy of which is filed as Exhibit 2.1 hereto and is incorporated by reference herein. The Merger Agreement has been attached to provide investors with information regarding its terms. It is not intended to provide any other factual information about the Company, Merger Sub or Adobe. In particular, the assertions embodied in the representations and warranties contained in the Merger Agreement are qualified by information in confidential disclosure letters provided by each of the Company and Adobe to each other in connection with the signing of the Merger Agreement or in filings of the respective parties with the United States Securities and Exchange Commission (the “SEC”). These confidential disclosure letters contain information that modifies, qualifies and creates exceptions to the representations and warranties and certain covenants set forth in the Merger Agreement. Moreover, the representations and warranties in the Merger Agreement were used for the purposes of allocating risk between the Company and Adobe rather than establishing matters of fact. Accordingly, the representations and warranties in the Merger Agreement should not be relied on as a characterization of the actual state of facts about the Company, Merger Sub or Adobe. 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, the Company, Merger Sub, Adobe, their respective affiliates and their respective businesses, that will be contained in, or incorporated by reference into, the proxy statement on Schedule 14A that the Company will file, as well as in the Forms 10-K, Forms 10-Q, Forms 8-K and other filings that the Company may make with the SEC.

Voting Agreements

In connection with the transaction, certain stockholders of the Company, (collectively, the “Support Stockholders”) have executed voting and support agreements (the “Voting Agreements”) in favor of Adobe concurrently with the execution of the Merger Agreement, pursuant to which such Support Stockholders have agreed, among other things and subject to the terms and conditions of the Voting Agreements, to vote certain shares of Company Common Stock owned by them in favor of the approval and adoption of the Merger and the Merger Agreement. The Support Stockholders represent approximately 75% of the votes of all issued and outstanding shares of the Company Common Stock entitled to vote on the adoption of the Merger Agreement. The Voting Agreements will terminate upon the earliest of (i) such date and time as the Merger Agreement shall be validly terminated, (ii) the effective time of the Merger, or (iii) any amendment of the Merger Agreement that (x) results in a decrease in, or a change to the form of, the consideration that would be payable to the Support Stockholders or (y) otherwise amends the Merger Agreement in a manner adverse in any material respect to the Support Stockholders.

The foregoing description of the Voting Agreement does not purport to be complete and is qualified in its entirety by the full text of the Voting Agreement, a copy of which is filed as Exhibit 10.1 hereto and is incorporated by reference herein.
