A class action lawsuit has already been filed. If you wish to serve as lead plaintiff, you must move the Court no later than July 27, 2026. A lead plaintiff is a representative party acting on behalf of other class members in directing the litigation.

According to the lawsuit, throughout the Class Period, defendants made false and/or misleading statements and/or failed to disclose that: (1) Calix's first quarter margins had significantly benefited from advanced purchasing of memory components; (2) Calix's advanced supply of memory components was dwindling; (3) as a result, Calix was experiencing negative margin pressure as it was forced to purchase memory components at rising market prices; and (4) as a result of the foregoing, defendants' positive statements about Calix's margins, business, operations, and prospects were materially misleading and/or lacked a reasonable basis. When the true details entered the market, the lawsuit claims that investors suffered damages.

No Class Has Been Certified. Until a class is certified, you are not represented by counsel unless you retain one. You may select counsel of your choice. You may also remain an absent class member and do nothing at this point. An investor's ability to share in any potential future recovery is not dependent upon serving as lead plaintiff.
