CALIX, INC. CLASS ACTION DEADLINE ALERT: Bragar Eagel & Squire, P.C.

Bragar Eagel & Squire, P.C., a nationally recognized stockholder rights law firm, announces that a class action lawsuit has been filed against Calix, Inc. (“Calix” or the “Company”) (NYSE:CALX) in the United States District Court for the Northern District of California on behalf of all persons and entities who purchased or otherwise acquired Calix securities between January 28, 2026 and April 21, 2026 , both dates inclusive (the “Class Period”). Investors have until July 27, 2026 to apply to the Court to be appointed as lead plaintiff in the lawsuit.

The complaint filed in this class action alleges that throughout the Class Period, Defendants made materially false and/or misleading statements, as well as failed to disclose material adverse facts about the Company’s business, operations, and prospects. Specifically, Defendants failed to disclose to investors: (1) the Company’s first quarter margins had significantly benefited from advanced purchasing of memory components; (2) that the Company’s advanced supply of memory components was dwindling; (3) that, as a result, the Company was experiencing negative margin pressure as it was forced to purchase memory components at rising market prices; and (4) that, as a result of the foregoing, Defendants’ positive statements about the Company’s margins, business, operations, and prospects were materially misleading and/or lacked a reasonable basis.
