02:49 PM EDT, 10/15/2025 (MT Newswires) -- STAAR Surgical ( STAA ) investors were urged to reject Alcon's ( ALC ) proposed acquisition by Institutional Shareholder Services.

ISS joined proxy advisory firms Glass Lewis and Egan-Jones Ratings in opposing the merger, Broadwood Partners, which holds more than 27% of STAAR, said Wednesday in a statement.

In early September, Broadwood Partners first criticized the sale process as flawed and the valuation as inadequate.

STARR didn't immediately reply to a request for comment from MT Newswires.

STAAR shares fell 4.2% in Wednesday trading, and Alcon ( ALC ) rose 0.5%.
