On January 23, 2026, at 12:00 a.m., New York City time, the "go-shop" period expired under the terms of the previously announced Agreement and Plan of Merger, dated as of December 20, 2025 (the "Merger Agreement"), by and among GT Silver BidCo, Inc., a Delaware corporation ("Parent"), GT Silver Merger Sub, Inc., a Delaware corporation and wholly owned subsidiary of Parent, and Clearwater Analytics Holdings, Inc., a Delaware corporation (the "Company").

Pursuant to the Merger Agreement, at the direction of the special committee (the "Special Committee") of the board of directors of the Company, representatives of PJT Partners LP, the independent financial advisor of the Special Committee, and J.P. Morgan Securities LLC, the financial advisor of the Company, actively solicited alternative acquisition proposals from 44 parties, consisting of 20 financial sponsors and 24 strategic parties. Six of these parties entered into confidentiality agreements and received access to a virtual data room containing non-public information about the Company. As of the expiration of the "go-shop" period, the Company did not receive an alternative acquisition proposal from any third party.

Upon the expiration of the "go-shop" period, the Company became subject to customary "no-shop" restrictions on its ability to solicit alternative acquisition proposals from third parties and to provide non-public information to and engage in discussions or negotiations with third parties regarding alternative acquisition proposals, subject to certain exceptions as set forth in the Merger Agreement.

Use of Forward-Looking Statements

This report contains "forward-looking statements" within the meaning of the safe harbor provisions of the Private Securities Litigation Reform Act of 1995. These forward-looking statements are based on management's beliefs and assumptions and on information currently available to management. Forward-looking statements include information concerning the Company's expectations with respect to the proposed transaction, including the timing thereof, and the Company's possible or assumed future results of operations, business strategies, technology developments, financing and investment plans, dividend policy, competitive position, industry, economic and regulatory environment, potential growth opportunities and the effects of competition. Forward-looking statements include statements that are not historical facts and can be identified by terms such as "anticipate," "believe," "could," "estimate," "expect," "intend," "aim," "may," "plan," "potential," "predict," "project," "seek," "should," "will," "would" or similar expressions and the negatives of those terms, but are not the exclusive means of identifying such statements.

Forward-looking statements involve known and unknown risks, uncertainties, and other factors, many of which are beyond the Company's control, that may cause the Company's actual results, performance, or achievements to be materially different from any future results, performance or achievements expressed or implied by the forward-looking statements. These risks and uncertainties may cause actual results to differ materially from the Company's current expectations and include, but are not limited to: (i) the risk that the proposed transaction may not be completed in a timely manner or at all; (ii) the failure to receive, on a timely basis or otherwise, the required approvals of the proposed transaction by the Company's stockholders; (iii) the possibility that any or all of the various conditions to the consummation of the proposed transaction may not be satisfied or waived, including the

failure to receive any required regulatory approvals from any applicable governmental entities (or any conditions, limitations or restrictions placed on such approvals); (iv) the occurrence of any event, change or other circumstance that could give rise to the termination of the definitive transaction agreement relating to the proposed transaction, including in circumstances which would require the Company to pay a termination fee; (v) the effect of the announcement or pendency of the proposed transaction on the Company's ability to attract, motivate or retain key executives and associates, its ability to maintain relationships with its customers, vendors, service providers and others with whom it does business, or its operating results and business generally; (vi) risks related to the proposed transaction diverting management's attention from the Company's ongoing business operations; (vii) the risk of shareholder litigation in connection with the proposed transaction, including resulting expense or delay; (viii) certain restrictions during the pendency of the proposed transaction that may impact the Company's ability to pursue certain business opportunities or strategic transactions; (ix) risks that the anticipated benefits of the proposed transaction are not realized when and as expected; (x) the availability of capital and financing and rating agency actions in connection with the proposed transaction; and (xi) other risks and uncertainties detailed in the Company's periodic public filings with the SEC, including but not limited to those discussed under "Risk Factors" in the Company's Annual Report on Form 10-K for the year ended December 31, 2024 filed on February 26, 2025 (as amended by Amendment No. 1 thereto, filed with the SEC on March 7, 2025), and in other periodic reports filed by the Company with the SEC. These filings are available at www.sec.gov and on the Company's website.

Given these uncertainties, you should not place undue reliance on forward-looking statements. Also, forward-looking statements represent management's beliefs and assumptions only as of the date of this report and should not be relied upon as representing the Company's expectations or beliefs as of any date subsequent to the time they are made. The Company does not undertake to and specifically disclaims any obligation to update any forward-looking statements that may be made from time to time by or on behalf of the Company.

Additional Information and Where to Find it

This report may be deemed to be solicitation material in respect of the proposed acquisition of the Company by Parent. In connection with the proposed transaction, the Company intends to file relevant materials with the Securities and Exchange Commission (the "SEC"), including the Company's proxy statement on Schedule 14A in preliminary and definitive form for its special meeting of stockholders to approve the proposed transaction, and may file or furnish other documents with the SEC regarding the proposed transaction. In addition, the Company and certain affiliates of the Company intend to jointly file a transaction statement on Schedule 13E-3 (the "Schedule 13E-3"). INVESTORS AND STOCKHOLDERS OF THE COMPANY ARE URGED TO READ ALL RELEVANT DOCUMENTS FILED WITH THE SEC, INCLUDING THE COMPANY'S PROXY STATEMENT AND SCHEDULE 13E-3 (IF AND WHEN THEY BECOME AVAILABLE) BECAUSE THEY CONTAIN OR WILL CONTAIN IMPORTANT INFORMATION ABOUT THE PROPOSED TRANSACTION.

Participants in the Solicitation

The Company and its directors, executive officers and other members of management and employees, under SEC rules, will be deemed to be "participants" in the solicitation of proxies from stockholders of the Company in favor of the proposed transaction.
