In a recent filing detailing insider activity, Michael Koralewski, the Chief Supply Chain Officer at First Solar, Inc. (NASDAQ:FSLR), sold 215 shares of common stock on May 5, 2026. The transaction was executed at a price of $215.63 per share, resulting in a total sale value of roughly $46,360.
This movement of shares follows an acquisition of 518 shares of common stock on May 4, 2026. That acquisition was the result of restricted stock units (RSUs) vesting. These RSUs were originally granted to Koralewski on May 1, 2025, and they vest at a rate of 25% on their first anniversary. Under the terms of the grant, each RSU provides the right to receive one share of First Solar common stock.
The sale of the 215 shares was conducted by the issuer for the purpose of satisfying specific tax withholding obligations tied to the vesting of these restricted stock units. Following these series of transactions, Koralewski maintains a direct holding of 14,642 shares of First Solar common stock, in addition to holding 1,556 restricted stock units.
The timing of this transaction comes during a period of significant upward momentum for the company's stock. First Solar shares have experienced a 73% surge over the past year and are currently trading at $219.38. Furthermore, the stock has seen a 15% gain within the last week alone. From a valuation standpoint, First Solar is trading at a P/E ratio of 14.18 and a PEG ratio of 0.43, metrics that suggest an attractive valuation relative to its growth. Analysis from InvestingPro indicates that the stock continues to trade at undervalued levels.
Looking at the broader financial context for First Solar, the company recently released its first-quarter 2026 earnings report. The results showed an earnings per share (EPS) of $3.22, which surpassed the anticipated $3.08 by a margin of 4.55%.
