Marx Dylan 4/A

What Happened Dylan Marx, Chief Operating Officer of Canadian Solar (CSIQ), exercised or converted 1,527 derivative shares on May 21, 2026 at an exercise price of $0.00 (code M). To cover tax withholding (code F), 903 of those shares were surrendered/withheld at $16.34 each, generating $14,758. Net shares added to his holding from this transaction were 624 shares (1,527 − 903). This is an exercise/conversion with shares withheld for taxes, a routine administrative outcome rather than an open‑market sale.

Key Details

• Transaction date: May 21, 2026
• Actions and codes: M = exercise/conversion of derivative (1,527 shares @ $0.00 acquired); F = tax withholding (903 shares @ $16.34 disposed) totaling $14,758
• Net new shares to insider: 624 shares retained after withholding
• Filing: Form 4 filed (and amended) on May 28, 2026; the amendment corrects a clerical error in the reported number of common shares beneficially owned
• Timeliness: The original transaction date (May 21) and filing date (May 28) indicate the Form 4 was filed/amended after the typical two‑business‑day reporting window (i.e., appears late)

Context This was a derivative exercise with a portion of the shares withheld to satisfy tax obligations (a common, routine occurrence). The F code means shares were used to cover withholding rather than sold on the open market, so it’s not a typical insider "sell" that signals liquidity taking. The amended filing only corrects the reported beneficial ownership number and does not change the transaction details.
