M&A Strategist

Acquisition adds $83.6 million revenue starting Q1'26; closing targeted in Q4'25, materially boosts scale.

SunPower plans a non‑binding LOI to buy Ambia Solar for $37.5 million in equity with a targeted close in Q4'25. The deal is stated to add $83.6 million of annual revenue starting Q1'26. Ambia is described as the No. 19 U.S. solar installer and brings an operational median order‑to‑install cycle of 41.6 days and an NPS of 71, plus a backlog that is 72% TPO at close.

The business mechanism is scale and operational integration: the transaction folds Ambia into SunPower’s Blue Raven division and reassigns senior leaders to preserve institutional knowledge. The announcement ties timing to policy shifts and company forecasts but provides concrete, auditable metrics: revenue contribution, closing quarter, cycle time, NPS, and TPO share. Key dependencies and risks are the contingency of a definitive agreement and customary closing conditions, plus execution of the stated synergy and integration steps within the stated quarters.

Watch the actual closing in Q4'25, the first post‑close revenue recognition in Q1'26, and whether the stated metrics (backlog composition of 72% TPO, $83.6 million revenue, 41.6‑day cycle time, NPS 71) appear in company filings or earnings. These items provide short‑term verification of the claimed impact and inform whether the announced operational shifts translate into the asserted financial benefit.

Adding $83.6 Million in Annual Revenue Starting in Q1’26

OREM, Utah, Nov. 11, 2025 (GLOBE NEWSWIRE) -- SunPower (herein “SunPower,” the “Company” or Nasdaq: “SPWR”) – a solar technology, services, and installation company – today announced that it has agreed to acquire Ambia Solar (“Ambia”), based in Lindon, Utah, just 1.7 miles from SunPower’s HQ. Ambia is the No. 19 U.S. solar company by installed megawatts as reported by Ohm Analytics. The companies have signed a non-binding LOI for $37.5 million in equity. The transaction will close this quarter (Q4’25), subject to customary closing conditions. (The verb “will” in this press release should be interpreted as “will pursue the result stated in a definitive agreement scheduled for Q4’25 and act vigorously to achieve that agreement thereafter.” It will also serve to highlight planned changes to investors and management alike.)

Based on three quarters of actual results and with one month left in Q4’25, Ambia’s 2025E revenue forecast is $83.6 million. The equivalent 2025E revenue forecast for SunPower is $303.4 million.

SunPower CEO, T.J. Rodgers said, “Ambia’s founding CEO, Conner Ruggio, is an ultra-marathon athlete, licensed pilot and holds an MBA from the University of Utah. He is a sales expert who believes that since the industry pays high commissions for solar sales contracts, winning sales teams should create more added value for their companies by performing the standard initial site survey, which is currently performed at SunPower by the operations team, adding a week of delay and added cost. After our deal is closed, Conner Ruggio will run our Blue Raven division, which Ambia will be merged into – appropriate, given that Ambia spun out of Blue Raven in 2022. Steve Erickson, the SunPower veteran who righted the ship as Blue Raven’s leader over the last year, will take over our new Battery Division, which focuses on battery storage and backup, the biggest opportunity in solar right now.”

Ambia CEO, Conner Ruggio, said, “We have a great opportunity to create significant value in the SPWR stock all Ambia employees will receive at the close by allowing us to bring to SunPower significant new revenue and substantial cost reductions through a formal synergy program which already has a first draft.”

SunPower CEO, T.J. Rodgers said, “We look forward to Ambia’s $83.6 million of added revenue – which will start in Q1’26, just as the ITC for individual homeowners expires – but I stress, as I did with our prior acquisition of Sunder, that the management team and its veteran solar employees are in themselves a big win for SunPower. For example, Ambia’s COO, Spencer Jensen, literally built the SunPower-Blue Raven operation that I chose on merit to be SunPower’s only operations area of the three possible candidates after the SPWR asset purchase. Spencer will be the Blue Raven COO, running all of our combined operations, with the goal of delivering to SunPower the operational improvements achieved at Ambia: a 41.6-day order-to-install median cycle time and NPS score of 71 awarded by customers.”

Spencer Jensen, who has a BS in Chemical Engineering from BYU and an MBA from the University of North Carolina, said, “I look forward to combining the two operations teams and moving them to the next level of operational performance. I also look forward to combining our two midwestern sales forces to bring each state to critical mass without increasing field overhead.”

Rodgers continued, “The SEIA has forecasted that the U.S. residential solar industry will install a massive 11 gigawatts (about $28 billion) – 6.0 gigawatts in 2025 and 5.2 gigawatts in 2026. Right now, due to the 2026 forecasted 13% ITC reduction, the industry is consolidating, giving publicly traded companies like SPWR an opportunity to join with leading private companies like Ambia – not to cash the founders out – but to let them invest in kind in a bigger and more durable company that they will also help run.”

Rodgers concluded, “The tangible benefits of the acquisition after closure will show up fully in Q1’26 financial statements, just when the new industry will be challenged with the ITC loss for homeowners, but not for Third Party Ownership, aka TPO-funded transactions. Fortunately, Ambia’s backlog will be 72% TPO at the close. This proposed acquisition reinforces SunPower’s existing financial forecasts to achieve record revenue and operating income in Q4’25, and to remain profitable in the double-jeopardy Q1’26 quarter.”

Non-GAAP Financial Measures

In addition to providing financial information based on generally accepted accounting principles in the United States of America (“GAAP”), this press release includes additional financial metrics that are not prepared in accordance with GAAP (“non-GAAP”). Management believes the non-GAAP financial measures, in addition to GAAP financial measures, are useful measures of operating performance for SunPower (as well as the combined business with Ambia) because the non-GAAP financial measure does not include the impact of items that management does not consider indicative of SunPower’s operating performance, including as a result of the acquisition of Ambia, such as amortization of goodwill and expensing employee stock options in addition to accounting for their dilutive effect, which facilitates the analysis of SunPower’s core operating results across reporting periods. The non-GAAP financial measures do not replace the presentation of SunPower’s GAAP financial results and should only be used as a supplement to, not as a substitute for, SunPower’s financial results presented in accordance with GAAP. Descriptions of and reconciliations of the non-GAAP financial measures used in this press release are included elsewhere in this press release. We encourage investors to carefully consider our projected operating results under GAAP, as well as our non-GAAP information and the reconciliations between these presentations, to more fully understand our business. Non-GAAP financial measures are reported in addition to, and not as a substitute for, or superior to, financial measures calculated in accordance with GAAP.
