The Portnoy Law Firm has announced a class action lawsuit on behalf of Calix, Inc. investors who purchased securities between January 28, 2026 and April 21, 2026. Investors have until July 27, 2026 to file a lead plaintiff motion. The lawsuit follows Calix's April 21, 2026 earnings report, which disclosed a sequential decline in non-GAAP gross margin to 57.2% and second-quarter guidance of 55.8% at the midpoint, down 140 basis points due to higher memory component costs. On an earnings call, CFO Cory Sindelar stated that advanced purchasing had previously shielded the company from these costs but that supply has now run out, and full-year non-GAAP gross margin is expected to decline between 50 and 150 basis points. On this news, Calix's stock price fell $6.93 per share, or 13.98%, to close at $42.65 per share on April 22, 2026.
