OREM, Utah, May 29, 2026 (GLOBE NEWSWIRE) -- SunPower Inc. ("SunPower," the "Company," or Nasdaq: "SPWR"), a solar technology, services, and installation company, today announced the successful completion of 26 Commercial Solar Projects for Starbuck's, which awarded the company a 90% Net Promoter Score (NPS), marking a significant milestone in SunPower's execution, quality and customer success strategy. NPS scores run from -100% to 100%, with scores above 70% considered world-class.

SunPower uses the NPS a quality method to measure the full customer experience. NPS is based on a standardized customer survey question: On a scale of 0 to 10, how likely are you to recommend this company to a friend or colleague? SunPower's NPS results thus reward a composite of customer experience, advanced product technology, installation quality, system activation performance, and ongoing customer support.

SunPower CEO, T.J. Rodgers said, "NPS performance rarely makes headlines, yet across our industry, the most common failure mode is inconsistent execution – leading to delays, customer dissatisfaction, and value erosion. After a year of focused effort, we were highly honored to receive an NPS score of 90% from Starbucks, a reflection of their view of SunPower's commitment to quality."

Surinder S. Bedi, Executive Vice President, Quality, Engineering and Customer Success at SunPower, added: "We worked diligently to achieve high NPS from Starbucks. SunPower's Quality Standard is to achieve a first-pass yield of 100% on every step – a true commitment to zero-defect quality, which, in turn, not only drives the lowest cost per kilowatt hour (kWh), but also the exceptional reliability and aesthetics that will serve Starbucks customers for decades."
