Shareholder rights law firm Robbins LLP informs investors that a class action was filed on behalf of persons or entities who purchased or otherwise acquired Tigo Energy (NASDAQ: TYGO) securities between February 24, 2026 and August 4, 2026, inclusive (the “Class Period”). Tigo provides solar and energy storage solutions, including module level power electronics (“MLPE”) designed to maximize the energy output of individual solar modules.
The complaint alleges that Tigo misled investors regarding the viability of the Company’s EG4 partnership.
Investors who suffered significant losses during the Class Period may be eligible to participate in the lawsuit and should contact Robbins LLP.
Why Was Tigo Sued?
According to the complaint, on August 25, 2025, Tigo announced a manufacturing and marketing partnership with EG4 Electronics (“EG4”), a company that manufactures solar energy products. Per Tigo’s press release, the partnership was intended to “produce Tigo optimized inverters and Module Level Power Electronics (MLPE) together with EG4 solar inverters.”
On May 5, 2026, Tigo issued its first-quarter 2026 financial results projecting revenue for FY 2026 of $130-135 million, and projected revenue of $30–$32 million for Q2 2026 specifically. Plaintiff alleges that these statements were materially false and/or misleading at the time they were made because: (1) the projections were based on the launch of the EG4 partnership and attendant revenue; (2) however, the EG4 partnership would not provide material revenue until Q4 2026 at the earliest; and (3) therefore, there was no basis for the projections.
Why did Tigo Stock Drop?
The complaint alleges that on August 4, 2026, Tigo reported its 2Q 2026 financial results in a press release. The press release stated that Tigo’s Q2 revenue was $25.4 million, versus the Company’s prior guidance of $30–$32 million. Furthermore, the Company revised its full-year 2026 guidance downward, reducing it from $130–$135 million to $100–$110 million—a midpoint reduction of approximately 20.8%.
The release quoted defendant Tigo’s CFO, who stated 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.” The “optimized inverter partner” referenced in the above quote is EG4. On this news, Tigo’s stock price fell from $2.04 on August 4 to $1.29 per share on August 5, a drop of approximately 37%.
Who May Be Eligible to Participate in the Tigo Class Action?
The lawsuit seeks to represent investors who purchased Tigo securities between February 24, 2026 and August 4, 2026. Investors who suffered losses during that period may have legal rights under the federal securities laws.
