This Transaction Statement relates to the Agreement and Plan of Merger, dated May 13, 2024 (including all exhibits and documents attached thereto, and as it may be amended, supplemented or modified, from time to time, the "Merger Agreement"), by and among Squarespace, Parent and Merger Sub. The Merger Agreement provides that, subject to the terms and conditions set forth in the Merger Agreement, Merger Sub will merge with and into Squarespace (the "Merger"), with Squarespace surviving the Merger and becoming a wholly owned subsidiary of Parent.

At the effective time of the Merger (the "Effective Time"), (1) each share of Company common stock issued and outstanding as of immediately prior to the Effective Time (other than shares held by (a) the Company, the Buyer Parties and any of their respective subsidiaries and the shares of Company common stock rolled over by (i) certain funds affiliated with Accel (the "Accel Rollover Entities"), (ii) GA SQRS II and (iii) Casalena pursuant to the Support Agreements (as defined below) (the "Owned Company Shares") and (b) stockholders who have neither voted in favor of the Merger nor consented thereto in writing and who have properly demanded appraisal of such shares of Company common stock pursuant to, and in accordance with, Section 262 of the General Corporation Law of the State of Delaware (the "DGCL")) will be cancelled and extinguished and automatically converted into the right to receive cash in an amount equal to $44.00, without interest thereon and subject to any applicable withholding taxes and (2) each Owned Company Share will be cancelled and extinguished without any conversion thereof or consideration paid therefor. Following the Merger, Company common stock will no longer be publicly traded, and the Company's stockholders (other than Accel (and certain of its affiliated funds), GA SQRS II and Casalena, indirectly) will cease to have any ownership interest in the Company.

In connection with entering into the Merger Agreement, on May 13, 2024, Parent and Squarespace entered into support agreements with (a) certain funds affiliated with Accel (the "Accel Supporting Entities"), (b) GA SQRS II and (c) Casalena (together, the "Support Agreements"). Pursuant to the Support Agreements, such stockholders have agreed, among other things, to vote all of their shares of Company common stock in favor of the adoption of the Merger Agreement and the approval of the Merger and against any other action, agreement or proposal which would reasonably be expected to prevent, materially impair or materially delay the consummation of the Merger or any of the transactions contemplated by the Merger Agreement, subject to the terms and conditions contained in the Support Agreements. In addition, the Accel Rollover Entities, GA SQRS II, the Casalena Foundation, the Anthony Casalena 2019 Family Trust and the Anthony Casalena Revocable Trust agreed to contribute to a direct or indirect parent company of Parent a portion of their respective holdings of Company common stock in exchange for equity interests in such a direct or indirect parent company of Parent. As a result of the Merger, the shares of Company common stock contributed to such direct or indirect parent company of Parent by the Accel Rollover Entities, GA SQRS II, the Casalena Foundation, the Anthony Casalena 2019 Family Trust and the Anthony Casalena Revocable Trust will be cancelled and extinguished without any conversion thereof or consideration paid therefor along with the other Owned Company Shares. In connection with entering into the Merger Agreement, on May 13, 2024, Intermediate 1 (an indirect parent of Parent), Casalena, GA SQRS II, ALF3 (for itself and as nominee for ALF3, ALF3E and ALFI20) and Accel Leaders 4 L.P. (for itself and as nominee for Accel Leaders 4 L.P., Accel Leaders 4 Entrepreneurs L.P. and Accel Leaders 4 Investors (2022) L.P.) entered into an interim investors agreement governing the relationship among the parties thereto between signing and closing of the Merger Agreement.

The board of directors of the Company (the "Board") formed a special committee of the Board comprised solely of independent and disinterested directors (the "Special Committee") to evaluate and negotiate a possible sale transaction involving the Company and other strategic alternatives and provide a recommendation to the Board as to whether or not to approve any such transaction. The Special Committee, as more fully described in the preliminary Proxy Statement, evaluated the Merger, with the assistance of its own independent financial and legal advisors. After careful consideration, the Special Committee, pursuant to resolutions adopted at a meeting of the Special Committee held on May 12, 2024, unanimously (1) determined that the Merger Agreement and the transactions contemplated thereby, including the Merger, are advisable, fair to, and in the best interests of Squarespace and the Unaffiliated Company Stockholders (as defined below), (2) recommended that the Board approve and adopt the Merger Agreement and the transactions contemplated thereby, including the Merger, and (3) resolved to recommend that the Unaffiliated Company Stockholders adopt the Merger Agreement. "Unaffiliated Company Stockholders" means the holders of Company common stock, excluding (1) General Atlantic, L.P., its investment fund affiliates and its portfolio companies majority owned by such investment fund affiliates, (2) Accel Management Co. Inc., its investment fund affiliates and its portfolio companies majority owned by such investment fund affiliates, (3) Permira Advisers, its investment fund affiliates and its portfolio companies majority owned by such investment fund affiliates, (4) Anthony Casalena and his controlled affiliates, (5) the members of the Board and (6) any person that Squarespace has determined to be an "officer" of Squarespace within the meaning of Rule 16a-1(f) of the Exchange Act.

The Board, acting upon the recommendation of the Special Committee, unanimously (1) determined that the Merger Agreement and the transactions contemplated thereby, including the Merger, are advisable, fair to, and in the best interests of Squarespace and its stockholders, (2) approved the execution and delivery of the Merger Agreement by Squarespace, the performance by Squarespace of its covenants and other obligations in the Merger, and the consummation of the Merger Agreement upon the terms and conditions set forth therein, and (3) resolved to recommend that Squarespace's stockholders adopt the Merger Agreement.

The Merger cannot be completed without the affirmative vote of (1) the holders of a majority in voting power of the outstanding shares of Company common stock; (2) the holders of a majority in voting power of the outstanding shares of Company common stock beneficially owned, directly or indirectly, by the Unaffiliated Company Stockholders; (3) the holders of a majority of the outstanding shares of Class A common stock; and (4) the holders of a majority of the outstanding shares of Class B common stock, in each case, to adopt the Merger Agreement.

Concurrently with the filing of this Amendment No. 1, the Company is filing Amendment No. 1 to its preliminary proxy statement (as amended thereby, the "Proxy Statement") under Regulation 14A of the Exchange Act with the SEC, pursuant to which the Company is soliciting proxies from the Company's stockholders in connection with the Merger.
