What Is The Lawsuit About?

The lawsuit has been filed on behalf of investors who purchased securities during the period of January 28, 2026 through April 21, 2026, inclusive (“the Class Period”). The lawsuit alleges 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; and (3) that, as a result, the Company was experiencing negative margin pressure as it was forced to purchase memory components at rising market prices.

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, the price of Calix shares declined by $6.93 per share, or approximately 14%, from $49.58 per share on April 21, 2026 to close at $42.65 on April 22, 2026.
