SCHEDULE 13D

Page 11 of 16

Item 1. Security and Issuer.

This Amendment No. 3 (this “Amendment No. 3”) to Schedule 13D (the “Statement”) is being filed to amend the Statement as originally filed with the U.S. Securities and Exchange Commission (the “SEC”) on May 20, 2024, as amended by Amendment No. 1 dated September 11, 2024 and Amendment No. 2 dated September 18, 2024, with respect to the Class A common stock, par value $0.0001 per share (the “Class A Common Stock”) of Squarespace, Inc., a Delaware corporation (the “Company”), whose principal executive offices are located at 225 Varick Street, 12th Floor, New York, New York 10014. Capitalized terms used herein and not defined herein have the meanings ascribed thereto in the Statement. Except as set forth below, all previous Items and disclosures set forth in the Statement remain unchanged.

Item 4. Purpose of Transaction.

Item 4 of the Statement is hereby amended and supplemented by the addition of the following:

The cash tender offer (the “Tender Offer”) by Spaceship Group MergerCo, Inc., a Delaware corporation (“Merger Sub”) and a wholly owned subsidiary of Spaceship Purchaser, Inc., a Delaware corporation (“Parent”), to purchase all of the outstanding shares of the Company’s common stock (collectively, the “Shares” and each, a “Share”) at an offer price of $46.50 per Share, expired as scheduled at one (1) minute after 11:59 p.m., New York City time, on October 11, 2024. As all conditions to the Tender Offer have been satisfied or waived, on October 14, 2024, Parent irrevocably accepted for payment all Shares validly tendered into and not validly withdrawn from the Tender Offer and paid for all such Shares in accordance with the Tender Offer.

On October 17, 2024, following the consummation of the Tender Offer, upon the terms and conditions set forth in the Amended and Restated Agreement and Plan of Merger, dated as of September 9, 2024, the Company filed a Certificate of Merger with the Secretary of State of the State of Delaware, pursuant to which the merger (the “Merger”) became effective. In the Merger, Merger Sub merged with and into the Company, with the Company continuing as the surviving corporation (the “Surviving Corporation”). As a result of the Merger, the Company ceased to be a publicly traded company and became a privately held company and a subsidiary of Parent, beneficially owned by Permira Portfolio Management Limited and certain of its affiliates and the Rollover Stockholders (as defined below).

Immediately prior to the effective time of the Merger (the “Effective Time”), each of (a) GA SQRS II, (b) Accel Leaders 3 L.P. and certain of its affiliated funds (collectively, “Accel”) and (c) Anthony Casalena, the Casalena Foundation and/or certain of their affiliates (collectively, “Casalena” and together with Accel and GA SQRS II, the “Rollover Stockholders”) contributed to an indirect parent company of Parent (“Topco”) a portion of their respective holdings of Shares (the “Rollover Shares”) in exchange for equity interests in Topco pursuant to their respective tender and support agreements. The remainder of the Rollover Stockholders’ respective holdings of Shares were sold to Topco pursuant to their respective tender and support agreements (collectively, the “Sale Shares”). At the Effective Time, each Share issued and outstanding immediately prior to the Effective Time (other than Shares (i) held by the Company and its subsidiaries, (ii) owned by Parent and Merger Sub (together, the “Buyer Parties”), (iii) that are Rollover Shares and Sale Shares, (iv) owned by any direct or indirect wholly owned subsidiary of the Buyer Parties as of immediately prior to the Effective Time, or (v) irrevocably accepted for purchase by Merger Sub in the Tender Offer, which were automatically cancelled and extinguished without any conversion thereof or consideration paid therefor), was converted into the right to receive an amount in cash equal to $46.50 per Share, without interest, and subject to deduction for any required tax withholding.

As a result of the Merger, the Class A Common Stock will no longer be listed on any securities exchange or quotation system, including the New York Stock Exchange (“NYSE”) and the Company will cease to be a publicly traded company. On October 17, 2024, NYSE filed an application on Form 25 with the SEC to withdraw registration of the Class A Common Stock under the Exchange Act. The deregistration will become effective 90 days after the filing of Form 25, or such shorter period as may be determined by the SEC. The Company intends to suspend its reporting obligations under the Exchange Act by filing a Form 15 with the SEC in approximately 10 days following the filing of the Form 25. The Company’s reporting obligations under the Exchange Act will be suspended immediately as of the filing date of the Form 15.

The consummation of the Merger and the other transactions described in this Item 4 have resulted or will result in a number of the actions specified in clauses (a)-(j) of Item 4 of Schedule 13D with respect to the Company, including the acquisition or disposition of securities of the Company, a merger or other extraordinary transaction involving the Company, a change to the board of directors of the Company (as the surviving corporation), causing a class of securities of the Company to be delisted from a national securities exchange, a class of equity securities of the Company becoming eligible for termination of registration and a change in the Company’s articles of incorporation and bylaws to reflect that the Company has become a privately held company.
