Should You Buy First Solar Stock For Its Cash?

For questions about this article or underlying research, email help@trefis.com.

First Solar (FSLR) stock trades 45.2% below its June 3, 2026 high, a decline that warrants a closer look. At today’s price, First Solar’s free cash over the last twelve months yields 8.0%, compared with 4.4% for the median S&P 500 company. A gap of that size marks either a business on sale or one the market expects to shrink. So what does a cash yield that high give you as an owner?

First Solar’s Free Cash Belongs To Its Owners

Shareholders own a portion of the free cash First Solar produces, just as they own a part of its profit, whether or not the company pays it out. Cash retained in the business still belongs to investors, and First Solar has kept its cash inside the company. Over the year to June 30, 2026, the company paid down most of its debt while increasing its cash and short-term investments from $1.15 billion to $1.73 billion. Over time, that cash can support the share price, more so if it keeps rising.

How Does First Solar Make Its Cash?

First Solar manufactures solar modules at a wide margin. Over the twelve months to June 30, 2026, the company posted an operating margin of 33.6%, nearly matching the 34.0% it reported two years earlier. Revenue during the same period rose 23.8% from a year earlier to $5.38 billion. First Solar reinvested about 30% of the cash from its operations into capital spending, leaving most of that cash as free cash flow. In the first half of 2026, that spending went mainly to its South Carolina finishing facility.

Generating this much leftover cash is a recent development. First Solar’s free cash flow over twelve months swung from an outflow of $0.943 billion in the year to June 2025 to an inflow of $1.5 billion a year later. The metric peaked at $1.67 billion in the twelve months to March 2026, and out of the last 13 such periods, only the four most recent finished above zero. Lenders have almost no claim on this money, since First Solar owed just $0.194 billion at June 30, 2026. Twelve-month sales growth and a steady margin look like a business on sale. But the company’s 2026 sales guide of $4.9 billion to $5.2 billion sits below its 2025 sales of $5.22 billion, so sales are expected to slip this year. The other catch is how recently the cash arrived.

Where Could First Solar’s Cash Come Under Pressure?

On the July 30, 2026 call, management said the policy environment still influences near-term customer activity. That environment includes a pending government investigation into polysilicon, and management could not say when a decision would come. Costs are rising too. Management described the increase in commodity costs as challenging and put the cost of underused capacity at around $30 million a quarter.

Net sales in the June 2026 quarter fell about 4% from a year earlier. Management said the drop happened mainly because revenue from customer contract terminations was lower than a year earlier. The company kept its 2026 net sales guidance unchanged at $4.9 billion to $5.2 billion, ending the quarter with contract backlog worth $13.6 billion. At 10.7 times earnings, compared with 23.0 for the S&P 500, the stock price appears to assume those worries win out.

What To Watch In First Solar’s Next Report

First Solar has not yet shown that its cash is steady. Twelve-month free cash flow slipped to $1.5 billion from its $1.67 billion March 2026 peak, and the company spent more cash than it brought in during each of the first two quarters of 2026. Its debt is the smaller question, since First Solar holds far more cash than it owes. The company’s next report, expected on or around October 29, 2026, will show whether that cash is holding up. Its free cash flow over twelve months is the number to watch.
