SunPower reported Q4 2025 revenue of $88.5 million, up 26% from $70.0 million in Q3, driven by full-quarter contributions from the Sunder acquisition and partial-quarter revenue from Ambia. GAAP gross profit for the quarter was $48.8 million (55% margin), while non-GAAP gross profit reached $50.9 million (57% margin). On a non-GAAP basis, operating income was $3.5 million (4.0% of revenue), compared with $2.0 million in Q3. The company closed the quarter with $9.3 million in cash, more than double the Q3 balance of $5.1 million. For full-year 2025, SunPower generated $308.8 million in revenue and $10.9 million in operating income, marking its first profitable year after four consecutive loss-making years under the prior ownership structure.

Management expects Q1 2026 revenue of approximately $84 million, with a variance of ±$4 million, reflecting the seasonal 10%–15% winter-quarter solar slowdown and the reduction in the ITC tax credit. Non-GAAP operating income is forecast at $2.0 million, and the company anticipates maintaining profitability throughout 2026. These projections exclude potential impacts from new partnerships or additional acquisitions currently under consideration.

Through the acquisitions of Sunder, Ambia and a recently closed Purelight deal, SunPower onboarded 1,446 commissioned sales representatives by quarter end (893 from Sunder, 203 from Ambia, 350 from Purelight), bringing the total to 1,977 reps. Despite this salesforce expansion, direct full-time headcount remained flat at 847 employees. This focus on acquisition synergies and headcount discipline drove record productivity of $445,000 revenue per employee—more than double the industry leader’s benchmark of $217,037. SunPower also executed a joint development agreement with REC to commercialize its ‘Monolith’ 470W frameless bifacial panel, with plans to exceed 500W output in future iterations.

To bolster liquidity, SunPower increased its equity line of credit with White Lion Capital to $55 million on January 11, providing a backstop to maintain cash above the $10 million threshold. Three additional financing deals are in progress. The company’s price-to-sales ratio remains near 0.55—a discount to peer Sunrun’s 1.75 and the high-tech index’s 2.2—prompting management to target a P/S multiple of 1.75, which would imply a threefold uplift in per-share valuation without considering share count changes. SunPower has also signed an LOI to acquire Cobalt Power Systems, which will install the first Monolith panels on a 111 kW project at Fortinet’s Sunnyvale headquarters, further accelerating market share gains in 2026.
