The transaction also represents over 20x enterprise value / 2025 unlevered free cash flow¹, representing a significant premium to peers.

The revised transaction is structured as a tender offer and is conditioned on a majority of the shares held by unaffiliated stockholders tendering into the offer. The amendment was unanimously approved and recommended by a Special Committee of the Squarespace Board of Directors, composed entirely of independent and disinterested directors, and unanimously approved by the Squarespace Board of Directors. All existing rolling shareholders have agreed to roll at the revised offer price.

"The Special Committee is pleased to announce the revised terms of our agreement with Permira," said Michael Fleisher, Chairman of the Special Committee of the Squarespace Board of Directors. "Our core focus has been maximizing value and certainty for the unaffiliated stockholders. This transaction is the result of a deliberate and thoughtful process and ultimately represents a great outcome that is in the best interest of Squarespace and all of its stockholders."

David Erlong, Partner at Permira, said, "We are pleased that the revised offer and merger agreement have been unanimously approved by Squarespace's Special Committee and Board of Directors and appreciate their focus throughout this process. This best and final offer allows Squarespace stockholders to capture immediate and certain value for their investment. By tendering their shares, Squarespace stockholders can act directly to accept the compelling value of this offer."

These forward-looking statements are based on the Company's current expectations, estimates and projections regarding, among other things, the expected date of closing of the Transaction and the potential benefits thereof, its business and industry, management's beliefs and certain assumptions made by the Company, all of which are subject to change. Forward-looking statements often contain words such as "expect," "anticipate," "intend," "aims," "plan," "believe," "could," "seek," "see," "will," "may," "would," "might," "considered," "potential," "estimate," "continue," "likely," "expect," "target" or similar expressions or the negatives of these words or other comparable terminology that convey uncertainty of future events or outcomes. By their nature, forward-looking statements address matters that involve risks and uncertainties because they relate to events and depend upon future circumstances that may or may not occur, such as the consummation of the Transaction and the anticipated benefits thereof. These and other forward-looking statements are not guarantees of future results and are subject to risks, uncertainties and assumptions that could cause actual

results to differ materially from those expressed in any forward-looking statements. Important risk factors that may cause such a difference include, but are not limited to: (i) the completion of the Transaction on anticipated terms and timing, including satisfying the minimum tender condition and obtaining any regulatory approvals, and the satisfaction of other conditions to the completion of the Transaction; (ii) the ability of affiliates of Permira to obtain the necessary financing arrangements set forth in the commitment letters received in connection with the Transaction; (iii) potential litigation relating to the Transaction that could be instituted against Permira, the Company or their respective directors, managers or officers, including the effects of any outcomes related thereto;
