Inverter and optimizer manufacturing partnership will bring Tigo products into the American domestic market manufacturing lines; companies to host joint session for installers at RE+ 2025 tradeshow.

LOS GATOS, Calif., August 25, 2025 — Tigo Energy, Inc. (NASDAQ: TYGO) ("Tigo" or "Company"), a leading provider of intelligent solar and energy software solutions, today announced a manufacturing and marketing partnership with EG4 Electronics, a leading American provider of innovative solar solutions, to produce Tigo optimized inverters and Module Level Power Electronics (MLPE) together with EG4 solar inverters in the United States of America. Solar installers in the U.S. currently already pair inverters from EG4 with Tigo MLPE devices, which have been certified as compatible.

The manufacturing partnership between Tigo and EG4 will build momentum to help bring critical energy manufacturing back to the United States and power reliable, homegrown solar solutions. In March 2025, EG4 Electronics' parent company, Energy Access Innovations (EAI), announced the acquisition of a state-of-the-art 310,000 sq. ft. manufacturing facility in Commerce, Texas. The facility is a further milestone for American energy independence and economic prosperity, creating more than 1,000 new American jobs and helping to advance the nation's energy security.

"We believe in energy autonomy for our customers just as much as we believe in manufacturing autonomy for American innovators, and this partnership with Tigo allows us to make significant progress on both of those fronts," said James Showalter, founder at EG4 Electronics. "This partnership with Tigo is exactly the kind of arrangement we had in mind when we announced our new manufacturing facility earlier this year. We look forward to building American-made energy infrastructure together with Tigo."

"EG4 is at the forefront of re-shoring manufacturing for American solar innovations, and we are delighted to work in partnership with James and his team," said Zvi Alon, chairman and CEO at Tigo Energy. "Tigo and EG4 are in alignment on some of the most critical success factors in solar, which include innovation and quality. This makes for a strong foundation for success, and I expect great things for American energy independence from this important collaboration."
