Provides Greater Value than STAAR Could Achieve on a Standalone Basis in the Foreseeable Future and is the Best Path Forward for STAAR Stockholders

Files Definitive Proxy Materials and Mails Letter to STAAR Stockholders

Encourages Stockholders to Vote “FOR” the Value Maximizing Alcon Merger Today

STAAR Surgical Company (NASDAQ: STAA), the global leader in phakic IOLs with the EVO family of Implantable Collamer® Lenses (EVO ICL™) for vision correction, today announced that it has filed its definitive proxy statement with the U.S. Securities and Exchange Commission in connection with the Company’s pending merger with Alcon (SIX/NYSE: ALC). STAAR will hold a Special Meeting of Stockholders on October 23 at 8:30 a.m. (Pacific Time) to vote to adopt the merger agreement. Stockholders of record as of the close of business on September 12, 2025, are entitled to vote at the meeting.

In conjunction with the definitive proxy filing, STAAR is mailing the following letter to STAAR stockholders:

Dear Fellow Stockholders,

On August 5, 2025, we announced that STAAR Surgical Company entered into a definitive merger agreement to be acquired by Alcon for $28.00 per share in cash. STAAR will hold a virtual Special Meeting of Stockholders on October 23 at 8:30 a.m. (Pacific Time) to ask for your vote to adopt the merger agreement. The STAAR Board of Directors unanimously determined that the proposed merger with Alcon is in the best interests of STAAR and its stockholders and strongly recommends that you vote “FOR” the merger proposal, as described in the accompanying proxy statement.

$28.00 per share is a compelling premium on multiple measures:

We believe the value provided by the Alcon merger exceeds what STAAR could achieve on a standalone basis in the foreseeable future, particularly given STAAR’s lower growth rate and the resulting impact on its valuation, and the substantial competitive and macro challenges in the markets STAAR serves. Our business is heavily exposed to China, which faces significant economic uncertainty and where sales trends have been declining despite actions taken by the Company.

Notably, STAAR’s common stock closed at only $18.49 per share just prior to the announcement of the Alcon agreement.

Vote “FOR” the Merger Proposal TODAY

Your vote is important because the merger is subject to approval by the holders of a majority of STAAR’s outstanding shares of common stock. Failure to vote will have the same effect as an “AGAINST” vote. To help ensure you receive the compelling, premium $28.00 per share cash value afforded by the Alcon merger please vote “FOR” the merger proposal TODAY.

If you have questions about voting your shares, please contact our proxy solicitor, Innisfree M&A Incorporated:

Stockholders, please call toll-free: (877) 750-8233. Banks and brokerage firms, please call: (212) 750-5833.

On behalf of the STAAR Board, thank you for your continued support of STAAR.

Sincerely,
