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.

On April 21, 2026, Calix announced its financial results for the first quarter of 2026, reporting that “Non-GAAP gross margin was 57.2%, down 80 basis points sequentially.” The Company also disclosed that “gross margin guidance for the second quarter of 2026 is between 54.25% and 57.25%” and that “[f]or the year, we expect our non-GAAP gross margin to decline between 50 and 150 basis points.” During the related earnings call, Calix’s CFO explained that “advanced purchasing had allowed us to avoid higher memory component costs during the first quarter. However, that advanced supply has run its course, and we now face market prices.” Following this announcement, Calix’s stock price fell $6.93 per share, or approximately 14%, declining from $49.58 per share on April 21, 2026 to close at $42.65 per share on April 22, 2026.
