First Solar (FSLR) CPO Patrick Buehler Sells Shares, Receives RSUs
What Happened
Patrick Buehler, Chief Product Officer of First Solar (FSLR), had restricted stock units (RSUs) convert/vest on March 6, 2026 and received a new RSU grant the same day. Several vested/converted shares (1,675 total) were recorded as acquired via conversion at $0.00 (vesting), and the company recorded a separate grant/award of 1,903 RSU units. On March 9, 2026 he sold 697 shares in open-market transactions at $190.36 per share for total proceeds of $132,680. The zero-price conversions indicate vesting of RSUs rather than cash purchases.
Key Details
- Vesting/conversion (listed as "M" exercise/conversion at $0.00) on 2026-03-06: 434, 189, 442 and 610 shares (total 1,675) converted/issued.
- Grant/award (listed as "A") on 2026-03-06: 1,903 RSUs granted.
- Open-market sales (listed as "S") on 2026-03-09: 181, 79, 184 and 253 shares sold at $190.36 each; proceeds ≈ $132,680.
- Purpose of sales: footnote states shares were sold to satisfy tax withholding on RSU vesting (sell-to-cover).
- Shares owned after the transactions: not specified in the filed summary.
- Filing: Form 4 filed 2026-03-10 for transactions dated 2026-03-06 — this filing date is four days after the transactions and appears later than the usual 2-business-day Form 4 deadline.
Context
- The M (exercise/conversion) entries here reflect RSUs vesting (conversion to common stock) at $0 cost to reflect issuance, not a cash purchase of stock.
- The subsequent open-market sales were routine sell-to-cover transactions to satisfy tax withholding obligations (per footnote), which are common and do not necessarily indicate a change in sentiment.
- Grants and ongoing RSU vesting are part of standard executive compensation (annual grants with multi-year vesting schedules per the footnotes). Purchases would be a stronger bullish signal; these transactions are mainly compensation-related.
