Executive Snapshot
On February 24, 2026, shares finished at $243.21, but after hours they dropped to $212.27 (-12.7%), indicating a strong post-release reaction.
First Solar Q4 net sales were $1.68 billion, which was a 7.0% surprise and more than the $1.57 billion projection.
The adjusted EPS of $4.84 was below the forecast range of $5.15 to $5.22 (a surprise of -6.3% to -7.3%).
With adjusted EBITDA of $2.6B to $2.8B and capital expenditures of $0.8B to $1.0B, the projected net sales for 2026 are $4.9B to $5.2B.
With a backlog of 50.6 GW as of February 24, 2026, and a record 2025 volume sold of 17.5 GW, demand visibility remains high.
What’s moving the stock now
The market is responding to a mixed quarter in which EPS declined, but revenue beat expectations following the FSLR earnings release.
Earnings missed expectations, but sales exceeded expectations. When that occurs, even if top-line demand appears fine, investors often think expenses, mix, or one-time factors were heavier than expected. The after-hours shift seems to be motivated by the "quality of earnings" debate.
There are several recognized cost headwinds and significant spending in the FSLR guidance 2026 projection.
The 2026 plan includes $100 million for perovskite research and development, $400 million for technology and R&D, and a substantial investment of $0.8 billion to $1.0 billion. Additionally, the projection includes specific cost elements such as manufacturing start-up expenses ($110M–$120M) and underutilization costs ($115M–$155M).
Exposure to tariffs is quantified explicitly.
Tariff-related expenses, such as $120–$130 million for imported bills of materials and $35–$45 million for imported completed modules, are included in the projection. Investor mood can be swiftly influenced by unambiguous figures like these.
The backlog and balance sheet continue to be stabilizers.
With $499 million in debt and $2.866 billion in cash and marketable securities at the end of 2025, the corporation still has more than 50 GW in backlog. These are important "support" points that investors keep an eye on, even amid erratic price movements.
Expectations Gap
Q4 2025 vs estimates:
- Net sales: $1.68B vs ~$1.57B → +7.0% surprise
- This indicates demand and deliveries were stronger than expected for the quarter.
- Adjusted EPS: $4.84 vs ~$5.15–$5.22 → -6.3% to -7.3% surprise
- This suggests that despite increasing sales, profitability (or below-the-line items) was lower than anticipated.
Guidance vs expectations (what matters next):
- 2026 net sales guidance: $4.9B–$5.2B
- 2026 Adjusted EBITDA guidance: $2.6B–$2.8B
- 2026 capex: $0.8B–$1.0B
The market's response indicates that investors are considering how the cost structure and investments in 2026 will affect earnings power.
Operating read-through
Despite the huge margins, investors are keeping an eye on what lies beneath.
The manufacturer's gross margin was 40.6% for the entire year 2025 and 39.5% for the fourth quarter. However, the EPS shortfall implies that the market's assessment of this quarter's sales beat was less significant than other expense lines (or non-operating items).
Demand visibility appears to be high based on bookings and backlog.
As of February 24, 2026, the backlog has increased to 50.6 GW from 50.1 GW at the end of 2025. The company further confirmed that it is shipping at scale by announcing a record 2025 volume shipped of 17.5 GW.
The 2026 plan shows stable volumes and a heavy investment cycle.
- 2026 volumes sold (global): 17.0–18.2 GW
- 2026 U.S. volumes sold: 12.6–13.1 GW
- ASP assumptions: ~30.8¢/W (U.S.) and ~28.7¢/W (global)
This is combined with large expenditures (R&D and capital expenditures) and cost factors (underutilization and start-up), which might put short-term profitability under pressure even if demand remains strong.
For the model, policy-linked credits are important.
Section 45X tax credits of $2.10 billion to $2.19 billion are assumed in the 2026 projection. Changes in time or eligibility could affect results because it is a significant factors in profitability predictions.
Valuation + positioning
Price behavior (near-term):
- Close: $243.21, after-hours: $212.27 (-12.7%)
- Short-term performance: +0.44% (1D), +1.94% (5D), -2.31% (1M), -7.51% (3M), +11.35% (YTD)
- Volume: 3,336,867 vs ~2,206,769 20D average (above-normal trading interest)
The above multiples indicate that the market is pricing in a lower forward earnings multiple than trailing:
- P/E: 18.6x trailing vs ~10.2x–10.5x forward (FY2026E)
- EV/EBITDA: 12.2x–12.4x trailing vs ~8.5x–9.1x forward
This arrangement usually indicates that investors anticipate stronger earnings in the upcoming year than in the previous 12 months; however, the after-hours action suggests that confidence in that trajectory may change quickly following guidance and quarterly results.
Catalysts
- Following through on the 2026 forecast, management is working toward net sales of $4.9 billion to $5.2 billion and adjusted EBITDA of $2.6 billion to $2.8 billion.
- Tariff effect management updates include whether the estimated cost headwinds ($120M–$130M BOM; $35M–$45M final modules) have changed.
- Ramp and utilization execution: how start-up costs ($110M–$120M) and underutilization ($115M–$155M) compare to the plan.
- Clarity regarding credit: the $2.10B–$2.19B Section 45X credit assumption is stable.
- Technology benchmarks: advancements in the roadmaps for perovskites and CuRe (while the investment cycle continues).
Risks
Sensitivity to profitability despite robust sales: Q4's sales beat, and EPS miss raise questions about cost structures and the caliber of earnings.
Policy and tariff risk: Credit assumptions and measured tariff costs are important determinants of 2026 results.
Execution risk on ramps and utilization: results may change if ramp time varies, and guidance specifically accounts for underutilization and startup expenses.
High investment load: if conditions improve, $0.8B to $1.0B in capital expenditures, as well as R&D and technology expenditures, may affect short-term free cash flow.
Shariah compliance
For investors reviewing Shariah-compliant stocks, FSLR, the screening status for First Solar is Pass. 98.49% of business activity is halal, 0.00% is doubtful, and 1.51% is not halal. Interest-bearing debt is shown at 3.99% and interest-bearing securities/assets at 11.54% on financial screens. The breakdown that was presented did not identify the primary cause of the Not Halal component.
Bottom line
Although the quarter's top line was clearly superior, the EPS shortfall and the market's -12.7% after-hours reaction indicate that investors are paying more attention to the 2026 plan's cost/investment profile and profitability specifics. The findings indicate that the company's ability to reliably meet its 2026 goals while controlling tariff costs, utilization/start-up costs, and credit-related assumptions will determine the near-term setup.
