Event Summary

Multiple law firms, including Robbins LLP, Glancy Prongay & Murray, Rosen Law Firm, and the The Law Offices of Frank R. Cruz, have filed or announced securities class action lawsuits against Calix, Inc. (NYSE: CALX) on behalf of investors who purchased Calix securities between January 28, 2026 and April 21, 2026. The lawsuits allege that Calix misled investors by failing to disclose that its first-quarter margins were significantly boosted by advanced purchasing of memory components, that its advanced supply of memory components was dwindling, and that the company was facing negative margin pressure due to rising memory component costs. On April 21, 2026, after Calix reported first-quarter earnings revealing lower gross margins and guidance for further declines, its stock price fell $6.93 (13.98%) to close at $42.65 per share on April 22, 2026. The lead plaintiff deadline is July 27, 2026.
