First Solar, Inc.: what insiders have been doing
First Solar, Inc., founded in 1999, is a Energy company based in Tempe, United States. Its directors and officers file their transactions with SEC (Form 4). The last twelve months, up to 18 October 2026, brought 116 filings signed by 25 insiders.
No insider bought on the market over the period, while 11 insiders filed 41 sales totalling €10.3M. The largest single trade was a sale of €2.5M by Stockdale Caroline, published on 1 June 2026, equal to 0.010% of the market capitalisation.
With 116 filings in twelve months, the company is more active than the median of 19 filings across the 5,811 companies we follow on the same exchange. The full history, which starts in 2016, counts 4 purchases against 142 sales. The 10-K for the year ended 31 December 2025 shows 5.22 bn USD of revenue and 1.53 bn USD of net income.
The median gap between a trade and its publication by SEC (Form 4) is 4 days. Section 16 rules allow two business days to file each Form 4. A sale on its own says little: insiders also sell to pay tax, fund a purchase or diversify.
In the same sector, recent insider purchases at RGC Resources Inc and Empire Petroleum Corp also feature in our signals. This summary is built from SEC (Form 4) disclosures alone and does not predict where the share price will go.

About First Solar, Inc.
First Solar, Inc. is a leading American solar technology and manufacturing company listed on the NYSE/NASDAQ in the United States. Founded in 1999, the company built its business around a differentiated photovoltaic platform: cadmium telluride (CdTe) thin-film technology, developed through R&D centers in California and Ohio. For investors, First Solar is not just a solar panel vendor; it is a vertically integrated industrial platform focused on utility-scale solar modules with an emphasis on performance, traceability, and supply-chain resilience.
The company’s core business consists of the design, manufacture, and sale of advanced thin-film solar modules, supplemented by post-sales support and recycling solutions. Its flagship products include the Series 6 and Series 7 module families, which are primarily targeted at large-scale solar projects rather than rooftop distributed generation. First Solar’s technology is positioned as an alternative to conventional crystalline silicon PV: it uses less semiconductor material, is produced through a streamlined integrated manufacturing process, and is marketed on advantages such as lower carbon intensity, lower water use, durability, and strong performance in hot or humid conditions. Those attributes are increasingly relevant for utility customers that prioritize long-life assets, bankability, and responsible sourcing.

From a historical standpoint, First Solar has become one of the most important U.S.-headquartered players in global solar manufacturing. Its headquarters are in Tempe, Arizona, and the company has built a substantial manufacturing footprint in the United States, with operational factories in Ohio, Alabama, and Louisiana, alongside production capacity in India, Malaysia, and Vietnam. Management has said it expects global annual manufacturing capacity of roughly 25 GW by 2026, underscoring both the scale of the platform and the company’s effort to align industrial expansion with policy support for domestic manufacturing.
Competitively, First Solar occupies a distinctive niche. It is the only U.S.-headquartered company among the world’s largest solar manufacturers, and it does not rely on the same Chinese crystalline-silicon supply chain as many peers. That differentiation can matter in procurement, tariff, and geopolitics-sensitive markets. Its CdTe technology is often framed as a strategic advantage because it combines industrial scale with a lower environmental footprint and a clear manufacturing narrative tied to American jobs and domestic capacity. This makes the company especially relevant in the context of the energy transition, U.S. industrial policy, and utility-scale decarbonization.
Recent developments have centered on capacity expansion and execution. First Solar has continued to invest in new manufacturing lines, including an Alabama facility intended to strengthen its North American footprint. Its latest annual reporting also indicates that a majority of its module sales are made to customers with projects in the United States, highlighting the importance of the domestic market in its revenue mix. For investors in France, Belgium, and Switzerland, First Solar offers a clean-energy industrial equity with exposure to U.S. solar build-out, manufacturing reshoring, and long-term demand for utility-scale renewable power, while remaining sensitive to solar pricing cycles, project timing, and policy-driven demand dynamics.
