Item 1. Security and Issuer.

This Amendment No. 2 (“Amendment No. 2”) to Schedule 13D (the “Statement”) amends the Statement 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, with respect to the Class A common stock, par value $0.0001 per share (the “Class A common stock”) and the Class B common stock, par value $0.0001 per share (the “Class B 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 is hereby amended and supplemented with 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 minute after 11:59 p.m., New York City time, on October 11, 2024. As all conditions to the Tender Offer were 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waived, on October 14, 2024, Parent irrevocably accepted for payment all Shares validly tendered into and not validly withdrawn from the Tender Offer and paid for all such Shares in accordance with the Tender Offer.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) the Casalena Foundation and/or certain affiliates of Anthony Casalena (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”), less and excluding, with respect to a portion of Casalena’s Shares, certain Shares that were eligible to be sold pursuant to any 10b5-1 Plan as of immediately prior to the Effective Time (the “Casalena 10b5-1 Shares”). At the Effective Time, the Casalena 10b5-1 Shares and each other 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.


CUSIP No. 85225A107		SCHEDULE 13D		Page 5 of 6

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.

Item 5. Interest in Securities of the Issuer.

Item 5 is hereby amended and restated in its entirety as follows:

The information set forth in Item 4 of this Amendment No. 2 is incorporated herein by reference.

(a) and (b) As of the date of this Amendment No. 2, the Reporting Person does not beneficially own any Class A common stock.

(c) Except as set forth herein and pursuant to, and in compliance with, a written plan that meets the requirements of Rule 10b5-1 under the Exchange Act in existence as of the date hereof, the Reporting Person has not effected any transaction in shares of Class A common stock in the past 60 days.

(d) Not applicable.

(e) At the Effective Time, each of the Reporting Person ceased to be the beneficial owner of more than 5% of the Class A common stock.

Item 6. Contracts, Arrangements, Understandings or Relationships with Respect to the Issuer.

Item 6 is hereby amended and supplemented as follows:

The information disclosed under Item 4 of this Amendment No. 2 is hereby incorporated by reference into this Item 6.

Item 7. Materials to be Filed as Exhibits.
