SunPower Completes the Integration of Sunder Energy

Integration Strengthens New Engine of Growth, Quality Standards, and Gains U.S. No 4 Spot

OREM, Utah, March 13, 2026 -- SunPower Inc. (“SunPower,” the “Company” or Nasdaq: “SPWR”) a solar technology, services, and installation company, today announced the successful completion of its integration of Sunder Energy, marking a significant milestone in SunPower’s growth and operational transformation strategy.

The Sunder Energy integration used SunPower’s structured stage-gate integration methodology to ensure consistent and disciplined execution across all corporate functions by embedding into Sunder SunPower’s quality systems, engineering rigor, and customer success standards.

SunPower Chairman and CEO, T.J. Rodgers said, “Usually closing an integration does not make headlines, but the most common acquisition failure mode is poor integration of the two companies, leading to devastating talent and value loss. We use a detailed acquisition process that has been successfully applied 28 times in three different companies, starting with Cypress Semiconductor. The process has five stage-gates: Integration Review Zero (IR0) creates a detailed plan with the 300 to 500 tasks needed to successfully integrate an acquisition. IR1 is achieved when basic corporate functions – finance, HR, admin, etc. – are fully integrated forming an engine to integrate the rest of the company. IR2, which contains the most tasks, is achieved when sales, products and customers are put on common platforms under common management. IR3 is achieved after the integration of the branding and pricing functions. Finally, IR4 requires us to successfully complete a giant checklist that is in turn reviewed by the six-person integration review board, which includes me. In other words, it is a thorough process which leads to permanent integration.”

Rodgers continued, “Each of the five Integration Reviews involves ten work groups – IT, HR, finance, sales, operations, quality, legal, facilities, customer success and marketing – which are led by a group of 20 managers, one from each side in each work group. That’s why Sunder’s 311 tasks took us six months to complete and are a significant accomplishment to us.”

The leader of the integration effort, Surinder S. Bedi, Executive Vice President, Quality, Engineering and Customer Success at SunPower, added: “SunPower’s Quality Standard for First Pass Yields is 100% which signifies a commitment to ‘First Time Right’ execution across IR1, IR2, IR3 and IR4 stage-gate execution phases – ensuring precision, accountability and value created at every step.”

Rodgers concluded, “Our integration pipeline now contains Ambia and Cobalt, which are scheduled for completion in May and June 2026, respectively. That leaves room for one more acquisition, for which we have two candidates.”
