First Solar’s Q1 Call Highlights Profits Amid Policy Risk

First Solar ((FSLR)) has held its Q1 earnings call. Read on for the main highlights of the call.

First Solar’s latest earnings call struck a confident tone, with management leaning on record first‑quarter revenue, powerful margin expansion, and a fortress‑like balance sheet to argue the business is gaining strength. Yet they also acknowledged that trade policy, tariff shifts, and underused overseas factories could pressure results if recent tailwinds fade.

Record Revenue and Volume Growth

First Solar delivered net sales of $1.0 billion in Q1, its strongest first quarter ever and 24% higher than a year ago. Module production reached 4.3 GW, led by roughly 3.0 GW from U.S. plants and 1.3 GW from international sites, with volumes sold jumping 31% year over year.

Margins, EBITDA, and Earnings Surge

Profitability was a standout as gross margin hit 47%, about six percentage points above last year, helped by scale and lower costs. Adjusted EBITDA climbed to $520 million, translating to a robust 50% margin, while net income rose 65% to $347 million, or $3.22 per diluted share.

Cash Strength and Balance Sheet Resilience

The company ended the quarter with $2.4 billion in cash, equivalents, restricted cash, and marketable securities, supporting a net cash position of $2.0 billion. Management highlighted this as the top end of their target range, giving First Solar ample flexibility to fund expansion and ride out policy or demand swings.

Efficiency Gains and Cost Discipline

Operational efficiency is improving, with sales freight cost dropping to about $0.017 per watt, roughly half last year’s level. Warehouse costs fell $22 million sequentially, part of an effort to strip out around $100 million of warehousing expenses by 2027 and support structurally higher margins.

CURE Technology Rollout

First Solar completed the CURE technology launch in Perrysburg and is ramping its Series 6 line with the upgrade. Management expects CURE to deliver up to roughly 8% more lifetime specific energy yield than crystalline silicon TOPCon and to unlock as much as $600 million of technology‑related revenue embedded in the backlog, mainly in 2027–2028.

Backlog Depth and Booking Trends

The company’s contracted backlog stood at 47.9 GW at quarter‑end, representing $14.4 billion in transaction value excluding future technology adjusters. Gross bookings reached about 1.9 GW since the prior call, including 1.7 GW in Q1 split between 0.9 GW in the U.S. at roughly $0.34 per watt and 0.8 GW in India.

Domestic Utilization and U.S. Manufacturing Push

U.S. facilities ran at about 96% utilization, underscoring strong domestic demand and policy‑driven momentum. The South Carolina finishing facility remains on track to begin production in 2026, with equipment installation already underway and expected benefits in freight, tariff exposure, domestic content, and related tax incentives.

Improving Cash Flow and Focused Capex

Operating cash outflow improved to $215 million, narrowing sharply from the prior‑year period’s $608 million outflow. Capital expenditures were $119 million, with spending largely directed toward the South Carolina finishing plant that should help optimize logistics and content economics.

Underused International Plants and Cost Headwinds

In contrast to the U.S., factories in Malaysia and Vietnam are running well below capacity amid trade uncertainty and weaker expected pricing for those modules. Management warned that underutilization charges will be higher in Q2, adding to cost pressure even as operational metrics improve elsewhere.

Tariff and Policy Risks Cloud Visibility

Executives emphasized that uncertainty around Section 232 measures, the Section 122 expiration window, proposed FEOP rules, and possible Section 301 actions is weighing on pricing and booking decisions. The company is being selective on new contracts, and its internal models assume no replacement tariffs beyond the current Section 122 window, which could change outcomes.

Underutilization Exposure and Guidance Assumptions

For the full year, First Solar has baked in $115 million to $155 million of underutilization costs tied to lower Southeast Asia use and the ramp of finishing lines. With utilization in Malaysia and Vietnam set to fall further in Q2, the company expects a noticeable uptick in associated charges even as overall profitability stays solid.

India Mix Pressures Pricing

Average selling prices came under pressure due to a larger share of modules shipped to India, where around 1 GW was sold domestically at about $0.20 per watt in Q1. While India still delivers attractive gross margins on a percentage basis, the lower dollar‑per‑watt pricing drags on blended ASPs and partly offsets other margin drivers.

Rising R&D and Launch Spending

Operating expenses reached $141 million, driven by $67 million in R&D, up $15 million year over year as the firm invests in perovskite development and CURE deployment. Management framed these as deliberate, near‑term cost increases aimed at securing long‑term technology leadership rather than transient overhead creep.

Backlog Execution and Capacity Reallocation

To support a planned 1 GW perovskite pilot line, First Solar is reallocating back‑end tools from existing lines, which trims finished‑module throughput in Malaysia and Vietnam. Management estimates slightly under 2 GW of fully finished capacity remains available from those plants for U.S. shipments, adding cadence and capacity risk that hinges on future tariff rules.

Regulatory and Execution Risks in India

Proposed changes to India’s ALMM framework, including possible minimum efficiency thresholds from 2027 and a cell‑level list, create another layer of execution risk. First Solar plans to introduce CURE in India to boost efficiency and energy attributes, but the evolving rules could influence project timelines and product qualification.

IP Litigation and Market Dynamics

The company is actively enforcing its intellectual property, with a Section 337 investigation launched in March that could lead to preliminary findings in about 11 months. Management flagged the risk of infringement among TOPCon manufacturers and indicated it is pursuing licenses where warranted, a strategy that could reshape competitive dynamics over time.

Near‑Term Margin Mix Headwinds

Guidance implies Q2 margins will be roughly flat with Q1 despite further savings in freight and warehousing as mix and utilization offset those gains. Lower use of Southeast Asia facilities and a higher share of lower‑priced output are expected to weigh on reported profitability in the short term even as structural cost improvements continue.

Perovskite Roadmap Still Unsettled

First Solar’s 1 GW perovskite pilot is targeted for 2027, but management was clear that early economics will be above high‑volume manufacturing costs. Durability and bankability will require substantial field data before the technology can be scaled, leaving both the cost curve and commercialization timing as key open questions for investors.

Guidance and Outlook

The company reaffirmed its full‑year 2026 outlook and guided Q2 volumes sold to 3.4–4.0 GW with adjusted EBITDA between $400 million and $500 million. It reiterated a full‑year module gross margin assumption of about 7% excluding incentives, with stronger performance in the back half, while assuming current tariff structures persist through the roughly 150‑day window but are not replaced afterward in its base case.

First Solar’s earnings call painted a picture of a manufacturer hitting its stride in the U.S. while navigating a shifting global trade and technology landscape. For investors, the story is one of strong current execution and balance‑sheet strength, tempered by policy, mix, and technology‑ramp risks that will determine how durable today’s elevated margins prove to be.
