First Solar (FSLR) Q3 2026 earnings review
First Solar profit rises 25%, but it cuts full-year sales
First Solar, the largest U.S. solar panel maker, earned more profit in the third quarter even as its shipments and revenue dropped. Net sales fell 23% from a year ago because the company delivered fewer panels, but U.S. manufacturing tax credits lifted gross margin to 58% and drove profit per share up 25%. Chief executive Mark Widmar praised U.S. trade rules and announced a $500 million share buyback, yet the company cut its full-year sales outlook by $300 million.
| Net sales | $1.23B -23% from a year ago |
|---|---|
| Gross margin | 57.9% +19.6 percentage points from a year ago |
| Contracted sales backlog | 44.0 GW 45.1 GW last quarter |
| Full-year sales outlook | Cut $300M middle of the range: $4.75B (-9%) |
⚖️ Verdict: 🔴 Bearish
The story got worse because customer shipment volume is now falling short of the full-year plan, while uncollected government tax credits reached $1.9 billion and pushed operating cash flow below zero. On the bright side, First Solar held its full-year gross profit target unchanged despite lower sales, and the quarterly drop in its order book slowed to 1.1 gigawatts.
The question now is whether the shipment cut reflects temporary customer delivery delays or weak demand for panels made at its Asian factories. If buyers simply pushed deliveries into 2027, the order book and U.S. pricing stay intact; if international demand is drying up, First Solar may have to shut idle foreign lines. Management's regional volume breakdown on the conference call will tell.
🐂 Bull Case
Lower Production Costs Keep Gross Margin Near 58%
First Solar makes thin-film solar panels in the United States, which earns the company federal manufacturing tax credits under Section 45X of the tax code. Those credits are recorded by reducing the cost of making the panels. Last quarter, a temporary $89 million tariff recovery estimate lifted gross margin to 57.3%, raising a concern that profitability would fall back once the one-off benefit passed.
Instead, third-quarter gross margin rose 19.6 percentage points from a year ago to 57.9%. The cost of making the panels dropped from 61.7% of revenue to 42.1%, offsetting a 4.0 percentage point rise in overhead, research, and factory start-up costs. First Solar also kept its full-year gross profit plan at $2.4 billion to $2.6 billion even after cutting its sales outlook by $300 million.
This matters because holding the gross profit target on lower sales lifts the full-year gross margin implied by the outlook from 49.5% to 52.6% by our math. However, the release did not update last quarter's tariff recovery estimate, and the full-year plan still points to fourth-quarter gross margin stepping down to about 49.1%.
What to watch: the manufacturing tax credit and tariff breakdown in the quarterly filing. It will show how much of the 57.9% gross margin came from U.S. factory mix versus any revision to tariff recoveries.
Trade Rules and New Orders Slow Backlog Drain
"Section 232 represents a structural change in how the United States approaches solar manufacturing," chief executive Mark Widmar said. Section 232 is a U.S. trade probe into imported polysilicon, the main material in rival Chinese solar panels. First Solar does not use silicon, so tariffs or quotas on silicon imports help its competitive position.
While the release did not print third-quarter shipments or new orders, the order book shrank by only 1.1 gigawatts (GW, a billion watts of power capacity) to 44.0 GW. By our math, the full-year and fourth-quarter shipment plans leave about 4.1 GW of third-quarter shipments, which means the company booked about 3.0 GW of net new orders in the quarter.
That 1.1 GW drawdown is less than half the 2.8 GW drop in the second quarter, so orders came closer to matching shipments. Still, the order book has fallen 18.1% over the past year because shipments continue to outrun new contracts.
What to watch: gross bookings and any contract cancellations on the conference call. Those figures will confirm whether new orders reached 3.0 GW and whether policy clarity is unlocking the 4 GW pipeline management discussed last quarter.
Positives this quarter didn't test
Three standing growth drivers from prior quarters rely on commercial details that First Solar gives in prepared remarks rather than the earnings release.
- U.S. booking prices and domestic-content mix: not in the release; the call's bookings commentary will show whether new U.S. contracts held near 36 cents per watt.
- CuRe (Copper Replacement, a panel efficiency upgrade) price adders: not in the release; the call or filing will show if customer notifications turned into higher contract value.
- Data-center developer demand: not in the release; management's pipeline update on the call will show whether large tech buyers signed new contracts.
🐻 Bear Case
Lower Shipments Force a $300 Million Sales Cut
Widmar said First Solar is positioned to benefit from U.S. trade policy and that its new share buyback reflects "confidence in the long-term value of the business". Last quarter, the company attributed a 3.7% revenue dip to one-off contract cancellation fees from a year earlier and kept its full-year sales and shipment targets unchanged.
This quarter, the solar manufacturer cut its 2026 shipment plan by 1.1 GW at the middle of the range and lowered its net sales outlook by $300 million. Third-quarter revenue dropped 22.8% from a year ago to $1.23 billion, "driven primarily by a decrease in the volume of modules sold to third parties".
- Third-quarter revenue: $1.23 billion, down 22.8% from $1.59 billion a year ago
- Full-year volume outlook: 16.0 to 17.0 GW, down from 17.0 to 18.2 GW
- Full-year net sales outlook: $4.6 billion to $4.9 billion, down from $4.9 billion to $5.2 billion
- Implied fourth-quarter revenue: $1.42 billion at the middle of the range, down 15.7% from a year ago by our math
This cuts against management's confidence narrative because customer delivery delays or weaker international demand are now hitting 2026 shipments. Even with high U.S. factory utilization, the company will sell about 5.7% fewer gigawatts this year than in 2025.
What to watch: the regional breakdown of the 1.1 GW volume cut on the call. A cut in U.S. shipments would mean domestic project delays, whereas an international cut would point to weak demand for panels made in Malaysia and Vietnam.
Uncollected Tax Credits Push Operating Cash Below Zero
First Solar books Section 45X manufacturing tax credits in profit as it sells U.S. panels, but it only collects the cash when the government pays out the refund or when the company sells the credits to another taxpayer. This year, the company stopped selling its credits at a discount and waited for direct government payments.
As a result, unpaid government grants on the balance sheet tripled from $625.2 million at the end of 2025 to $1.87 billion at the end of September. That $1.29 billion buildup drained working capital and pushed nine-month operating cash flow to negative $402.7 million, compared with positive $815.2 million a year ago.
Net cash fell from $2.4 billion at year-end to $1.5 billion, "driven by working-capital needs and capital expenditures primarily for our U.S. facilities, partially offset by Section 45X cash receipts and IEEPA tariff refunds received". Because First Solar still plans to end 2026 with $1.7 billion to $2.3 billion of net cash, it must collect roughly $500 million of cash in the fourth quarter to reach the middle of its plan.
What to watch: fourth-quarter cash collections from the U.S. Treasury. Any processing delay at the Internal Revenue Service would cause First Solar to miss its year-end net cash outlook.
Risks this quarter didn't answer
Five standing concerns from last quarter were not addressed in the earnings release and wait on the conference call or quarterly filing.
- Idle Southeast Asia factories: full-year underutilization costs edged down to $110–120 million from $115–135 million, but the release gave no decision on the 1.8 GW of idle capacity.
- Raw material and U.S. trucking inflation: not in the release; the call's margin bridge will show whether domestic freight costs kept rising.
- Customer collateral hurdles: not in the release; Q&A will show if buyers still struggle to post cash security on new contracts.
- South Carolina factory and perovskite pilot line: full-year start-up expense fell by $10 million, but the release gave no timeline or budget update.
- Section 301 excess-capacity tariff probe: not in the release; the call will show if new tariffs threaten panels from Malaysia and Vietnam.

Board Approves $500 Million Buyback as Capex Slows
First Solar's board approved a $500 million share repurchase programme with no expiration date. At the same time, the solar maker trimmed its 2026 capital spending plan by $200 million to a range of $600 million to $800 million. Nine-month capital spending fell 37.7% from a year ago to $434.7 million, leaving $265.3 million for the fourth quarter by our math.
💲 Other KPIs
Current and long-term inventories rose 34.8% from $974.2 million at the end of 2025, and grew 3.1% from $1,273.6 million last quarter. The buildup comes as third-quarter revenue fell 22.8% from a year ago and management cut its full-year shipment target by 1.1 GW, tying up $349.0 million of cash over the first nine months.
Deferred revenue — upfront deposits customers pay before First Solar delivers their panels — fell 12.2% from $1,819.4 million at the end of 2025 and 6.0% from $1,698.9 million in the second quarter. As the company delivers panels against old contracts faster than it collects deposits on new ones, the drawdown reduced nine-month operating cash flow by $220.7 million.
Spending on research and development rose 10.9% from $60.6 million a year ago, and jumped from 3.8% of revenue to 5.5% because sales declined. Over the first nine months, research spending climbed 25.6% to $210.4 million as the solar group invests in next-generation panel technology.
🔮 Guidance
Cut. The middle of the range dropped by 1.1 GW to 16.5 GW, which means full-year shipments will fall 5.7% from 17.5 GW in 2025. First Solar had held the previous range through three updates since February. With 7.6 GW shipped in the first half and 4.3 to 5.3 GW planned for the fourth quarter, the outlook leaves about 4.1 GW for the third quarter by our math.
Cut. Management lowered the middle of the range by $300 million to $4.75 billion, pointing to a 9.0% revenue drop for the year after holding the target flat for three quarters. By our math, subtracting nine-month sales of $3.33 billion leaves $1.42 billion for the fourth quarter, down 15.7% from $1.68 billion a year ago.
Unchanged. The plan still has gross profit rising 17.9% at the middle of the range to $2.50 billion, including $2.07 billion to $2.19 billion of manufacturing tax credits and $110 million to $120 million of factory underutilization costs. By our math, that leaves $695.8 million of gross profit for the fourth quarter, or a 49.1% gross margin, down from 57.9% in the third quarter.
Unchanged. Full-year operating costs stay at $622.5 million at the middle of the range, up 18.9% from 2025, while the assumption for factory start-up costs inside that total dropped by $10 million to a range of $80 million to $90 million. By our math, the outlook leaves $160.1 million of operating expenses for the fourth quarter, down from $167.0 million in the third quarter.
Cut. The panel maker trimmed the middle of the range by $50 million to $2.65 billion, which still represents 12.2% growth over 2025. The reduction is much smaller than the $300 million revenue cut because U.S. tax credits and lower start-up addbacks protect profit.
Cut. Planned spending on factories and equipment dropped by $200 million at the middle of the range to $700 million, a 19.5% decrease from $869.9 million in 2025. After $434.7 million of spending in the first nine months, the plan leaves $265.3 million for the fourth quarter by our math.
Unchanged. First Solar still expects to finish the year with $2.0 billion of net cash at the middle of the range, down from $2.4 billion at the end of 2025. Reaching that midpoint from September's $1.5 billion balance requires a $500 million cash inflow in the fourth quarter, aided by the $200 million cut to capital spending.
New. The fourth-quarter plan calls for 4.8 GW of shipments at the middle of the range, including 3.4 to 4.3 GW from U.S. factories. By our math, that is up from about 4.1 GW of total shipments in the third quarter.
New. Fourth-quarter operating profit before depreciation and one-offs is set for $743 million at the middle of the range, matching the $744 million delivered in the third quarter despite higher planned shipments.
❓ Key Questions
What were Q3 shipments, gross bookings, and cancellations?
The earnings release gave the 44.0 GW ending backlog but omitted third-quarter volume sold and gross bookings. Investors need the exact rollforward to verify whether net orders reached 3.0 GW and whether any customer contracts were cancelled.
Where did the 1.1 GW full-year shipment cut come from?
First Solar cut its 2026 volume outlook from 17.0–18.2 GW to 16.0–17.0 GW while holding its gross profit range flat. That combination suggests the lost shipments carried low margins, likely from international factories, or that customer delivery delays pushed volume into 2027.
When will the Treasury pay the $1.87 billion of tax credits?
Total government grants receivable tripled over the first nine months to $1.87 billion, pushing operating cash flow to negative $402.7 million. Reaching the $2.0 billion net cash midpoint requires collecting a large portion of the $286.9 million current receivable before December.
Why cut capital spending by $200 million right now?
Management trimmed 2026 capital expenditures from $0.8–1.0 billion to $0.6–0.8 billion and lowered start-up expense by $10 million. We need to know if equipment payments for the South Carolina factory or the perovskite pilot line slipped into 2027.
