SUNation Secures $835 Million to Fund Major U.S. Solar Cell Manufacturing Facility

The financing was backed by a broad group of investors, including Lion Point Capital, Goldman Sachs Alternatives, I Squared Capital, JBA Asset Management, Electron Capital Partners, Orion Infrastructure Capital and Rubric Capital.
The planned Laurens County facility will occupy a 621,468-square-foot building whose shell has already been completed; operations are expected to begin in late 2027, with the plant reaching full production in 2028.
Under the June 5 merger agreement, SUNation Merger Sub is expected to merge into Suniva, with Suniva continuing as a wholly owned subsidiary of SUNation and surviving as the merger entity, subject to the agreement’s conditions.
GuruFocus reported that SUNation’s price-to-sales ratio was about 0.14 times, compared with a historical median of 0.08 times, while its GF Score was 23 out of 100, reflecting continuing profitability and momentum concerns.
The company reported $1.2 million in net insider purchases over the prior 12 months, with no insider selling, although one premium guru investor had recently reduced its position.
SUNation Energy secured $835 million in financing to build a second U.S. solar-cell factory in South Carolina, marking a major bet on domestic manufacturing. Pulse2 reported the deal will expand the combined company's American solar-cell capacity from 1 gigawatt to 5.5 gigawatts by late 2027. The financing round included backing from Lion Point Capital, Goldman Sachs Alternatives, and six other major investors.
SUNation shares surged 24.9% in after-hours trading on the announcement. The $600 million Laurels County plant is expected to create 564 jobs and reach full production in 2028. However, GuruFocus noted the company remains unprofitable, with a GF Score of just 23 out of 100, signaling execution risks ahead.
The Laurens County facility will occupy a 621,468-square-foot building with shell construction already complete. PV Magazine USA reported operations are expected to begin in late 2027, with the plant hitting full production in 2028. The expansion nearly quintuples current domestic manufacturing capacity.
The financing supports a June 5 merger agreement where SUNation Merger Sub combines with Suniva. Suniva will become a wholly-owned subsidiary and survive as the merger entity. The deal strengthens the domestic solar supply chain through long-term customer agreements and expanded capacity.
Seven major investment groups put money behind the deal. Pulse2 listed the investors as Lion Point Capital, Goldman Sachs Alternatives, I Squared Capital, JBA Asset Management, Electron Capital Partners, Orion Infrastructure Capital, and Rubric Capital. The mix of debt and equity financing shows confidence in the domestic solar sector's growth.
Insiders have shown bullish conviction on SUNation. The company reported $1.2 million in net insider purchases over the prior 12 months with zero insider selling. This suggests management believes the merger and expansion will succeed.
QuiverQuant reported SUNation surged as high as 43.2% on merger-related optimism. After-hours trading showed a more modest 24.9% gain following the financing announcement. The stock is trading like a turnaround story—real revenue but still unprofitable.
Valuation metrics show mixed signals. GuruFocus noted SUNation's price-to-sales ratio hit about 0.14 times versus a historical median of 0.08 times. The company's low GF Score reflects ongoing concerns about profitability and whether it can execute the ambitious expansion on time.
