NEW YORK, June 13, 2026 (GLOBE NEWSWIRE) -- Faruqi & Faruqi, LLP, a leading national securities law firm, is investigating potential claims against Calix, Inc. (“Calix” or the “Company”) (NYSE: CALX) and reminds investors of the July 27, 2026 deadline to seek the role of lead plaintiff in a federal securities class action that has been filed against the Company.

Faruqi & Faruqi is a leading national securities law firm with offices in New York, Pennsylvania, California and Georgia. The firm has recovered hundreds of millions of dollars for investors since its founding in 1995. See www.faruqilaw.com.

As detailed below, the complaint alleges that the Company and its executives violated federal securities laws by making false and/or misleading statements and/or failing to disclose that: (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 reported results for the first quarter of 2026 earnings, including that "Non-GAAP gross margin was 57.2%, down 80 basis points sequentially." Further, the Company reported "gross margin guidance for the second quarter of 2026 is between 54.25% and 57.25%" and "[f]or the year, we expect our non-GAAP gross margin to decline between 50 and 150 basis points."

In the accompanying earnings call, the Company’s CFO stated "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."

On this news, Calix's stock price fell $6.93, or 13.98% to close at $42.65 per share on April 22, 2026, on unusually heavy trading volume.

The court-appointed lead plaintiff is the investor with the largest financial interest in the relief sought by the class who is adequate and typical of class members who directs and oversees the litigation on behalf of the putative class. Any member of the putative class may move the Court to serve as lead plaintiff through counsel of their choice, or may choose to do nothing and remain an absent class member. Your ability to share in any recovery is not affected by the decision to serve as a lead plaintiff or not.  

Faruqi & Faruqi, LLP also encourages anyone with information regarding Calix’s conduct to contact the firm, including whistleblowers, former employees, shareholders and others.

The Calix securities fraud lawsuit is a federal securities class action alleging that Calix, Inc. (NYSE: CALX) and its executives made false and misleading statements to investors by concealing that the Company's strong first quarter margins were artificially inflated by advanced purchasing of memory components, that its advanced supply of those components was dwindling, and that it would soon be forced to purchase memory components at rising market prices — creating significant negative margin pressure. As the truth emerged on April 21, 2026, when Calix reported Q1 2026 results and its CFO disclosed that "advanced supply has run its course" and the Company would "now face market prices," CALX's stock price fell $6.93 per share, or 13.98%, causing significant losses for investors.
