First Solar surged in afternoon trading after a prominent analyst firm reversed course on the stock, raising both its rating and its price target. GLJ Research moved its recommendation to Buy from Hold and lifted its target to $315, up from $207.82. The firm cited a materially lower risk of contract debookings and framed an approaching Section 232 decision on polysilicon imports as an imminent positive catalyst for the company.
The upgrade represents a stark turnaround from the same firm's downgrade less than three months earlier. Market commentary around the Section 232 review of polysilicon has circulated for some time; Roth Capital had earlier described the probe as likely to be a positive catalyst for First Solar, highlighting the company’s cadmium telluride (CdTe) thin-film technology as insulated from tariff or trade issues affecting silicon-based solar manufacturers.
Price action for First Solar had already been strong heading into the day of the upgrade. The stock entered the session on a five-day winning streak, with cumulative gains of roughly 23% over that period. That momentum translated into an approximate $5.6 billion increase in the company's market capitalization ahead of the GLJ move.
Fundamentals also provided supporting context for the analyst re-rating. First Quarter 2026 results topped analyst expectations, with reported earnings per share of $3.22 versus consensus estimates of $2.87, and revenue of $1.04 billion. Those results form a part of the rationale that appears to be underpinning renewed optimism among some sell-side voices.
The broader equity market offered a constructive but limited lift on the day. The S&P 500 advanced 0.6% while the NASDAQ rose 0.9%, a risk-on tone that was modest compared with the outsized move in First Solar's shares. The company benefited disproportionately from sector-specific policy dynamics tied to the Section 232 investigation.
The Section 232 inquiry itself was launched by the U.S. Secretary of Commerce on July 1, 2025. The probe is evaluating whether imports of polysilicon and related derivatives constitute an impairment to U.S. national security. Market observers and some analysts view that process as offering a competitive edge to domestic thin-film producers, a category that includes First Solar.
Beyond near-term trading drivers, First Solar has an explicit capacity-growth timeline that market participants are watching. The company plans to bring a sixth domestic manufacturing facility online in South Carolina in the second half of 2026. Management projects that, once this facility is fully ramped in 2027, First Solar will have more than 17 GW of annual domestic nameplate capacity. The GLJ Research upgrade appears to factor that longer-term capacity build and its potential implications for the company's outlook into the refreshed valuation.
Analysis - What moved the stock
Three primary elements converged to produce the sharp intraday move: the abrupt analyst re-rating, the market expectation of a beneficial Section 232 outcome for domestic thin-film producers, and the stock’s own recent momentum following a multi-day rally. While broader indices were up modestly, none of those moves account for the full magnitude of First Solar’s gain, which was concentrated in the company’s shares and sector.
Investors will likely monitor the timing and substance of any Section 232 decision closely, along with execution on First Solar’s planned capacity expansion in South Carolina and how quickly that incremental nameplate capacity ramps toward the company’s 2027 target.
