SunPower Corp. (NASDAQ: SPWR) announced the completion of its integration of Sunder Energy, following a six-month process involving 311 tasks across multiple corporate functions.

The solar technology and installation company used what it calls a structured stage-gate integration methodology with five phases, designated as Integration Reviews IR0 through IR4. The process involved ten work groups including IT, HR, finance, sales, operations, quality, legal, facilities, customer success and marketing, led by 20 managers.

"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," said T.J. Rodgers, SunPower's chairman and CEO, in a statement.

Rodgers said the company has applied this integration process 28 times across three different companies, beginning with Cypress Semiconductor. The methodology begins with IR0, which creates a detailed plan with 300 to 500 tasks, and concludes with IR4, which requires completion of a checklist reviewed by a six-person integration review board.

The integration embedded SunPower's quality systems, engineering standards and customer success protocols into Sunder Energy's operations. Surinder S. Bedi, executive vice president of quality, engineering and customer success at SunPower, stated the company maintains a quality standard for first pass yields of 100%.

SunPower has two additional acquisitions in progress: Ambia and Cobalt, scheduled for completion in May and June 2026, respectively. Rodgers indicated the company has two candidates for a potential fourth acquisition.
