Background

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, thereby injuring investors.
