COMPLAINT ALLEGATION SUMMARY:
Tigo provides solar and energy storage solutions, including module level power electronics designed to maximize the energy output of individual solar modules.

The complaint alleges that, throughout the Class Period, Defendants made materially false and/or misleading statements, as well as failed to disclose material facts about the company’s business, operations, and prospects. Specifically, Defendants misrepresented and/or failed to disclose that: (1) the company’s 2025 financial guidance was erroneously based off of its manufacturing and marketing partnership with EG4 Electronics (“EG4”); (2) in reality, the EG4 partnership would not provide material revenue until at least Q4 2026; and (3) as a result of the foregoing, Defendants’ statements about the company’s business, operations, and prospects were materially false and misleading and/or lacked a reasonable basis at all relevant times.

WHY DID TIGO’S STOCK DROP?
On August 4, 2026, Tigo reported its Q2 2026 financial results, revealing that its’ revenue fell below prior guidance. Furthermore, the company reduced its full-year 2026 guidance by approximately 20.8%, stating that “[t]he revision to our full-year 2026 outlook reflects our U.S. optimized inverter partner’s shift of its go-to-market launch to the fourth quarter, the slower ramp of our new GO Battery, and a more gradual recovery in Europe.” On this news, the price of Tigo’s stock fell approximately 37%.

THE LEAD PLAINTIFF PROCESS:
The Private Securities Litigation Reform Act of 1995 permits any investor who purchased or acquired Tigo securities during the Class Period to seek appointment as lead plaintiff in the Tigo class action lawsuit. A lead plaintiff is a representative party that acts on behalf of other class members in directing the litigation. In order to be appointed lead plaintiff, the Court must determine that the class member’s claim is typical of the claims of other class members, and that the class member will adequately represent the class. Your ability to share in any recovery is not, however, affected by the decision whether or not to serve as a lead plaintiff. Filling out the online form above or communicating with any counsel is not necessary to participate or share in any recovery achieved in this case. Any member of the purported class may move the court to serve as a lead plaintiff through counsel of his/her choice, or may choose to do nothing and remain an inactive class member.
