New York, January 17, 2026, 19:22 EST — Market closed
First Solar, Inc. shares ended Friday nearly unchanged at $243.73, up 0.04%, after trading between $243.01 and $248.43. About 2.0 million shares changed hands.
That flat finish came after a sharper move a day earlier and leaves the solar manufacturer heading into the long weekend with investors looking for the next push — from rates, policy headlines and, eventually, guidance.
U.S. stocks ended nearly flat on Friday and all three major indexes logged weekly losses as fourth-quarter earnings season got going. “Most investors will take that as a win,” said Anthony Saglimbene, chief market strategist at Ameriprise Financial, with Wall Street shut on Monday for the Martin Luther King Jr. holiday. 1
First Solar climbed about 3% on Thursday, closing at $243.64 after swinging from $234.81 to $252.52 in the session, according to trading data. 2
Solar names finished mixed on Friday. The Invesco Solar ETF slipped 0.15%, while Enphase fell 1.1% and Sunrun edged down 0.1%; SolarEdge added 0.3%.
First Solar, based in Arizona, makes thin-film photovoltaic modules — panels that turn sunlight into electricity — and sells into utility-scale projects. 3
At its last quarterly update in October, the company said it would establish a 3.7 gigawatt (GW) U.S. finishing facility — GW is a measure of power capacity — with production expected to start at the end of 2026 and ramp through the first half of 2027. CEO Mark Widmar told investors the plan puts First Solar “at the intersection of several of the administration’s key priorities,” and the company also trimmed its 2025 sales outlook after customer terminations. 4
But the setup cuts both ways. If policy support for domestic solar manufacturing shifts, or if project financing costs rise, developers can delay orders and the stock can gap before buyers show up.
With trading set to resume on Tuesday, investors will watch whether clean-energy names keep tracking broader risk appetite or start moving on company-specific signals again. Thin volume after a holiday can magnify the first move.
The next clear marker on the calendar is First Solar’s quarterly report. Nasdaq’s earnings calendar pegs the release for Feb. 24, though the company has not confirmed a date. 5
