Valduga Anthony P. 4

What Happened

Anthony P. Valduga, CoastalSouth Bancshares’ CFO and COO, converted 13,000 restricted stock units (RSUs) into 13,000 shares on April 27, 2026 (exercise/conversion of derivative, code M). To cover tax withholding (code F), 3,841 of those shares were surrendered/issued back at $25.59 per share, yielding approximately $98,291. The RSUs converted at no exercise price ($0), so no cash was paid to acquire the underlying shares; net shares retained from the conversion were 9,159.

Context

This was an RSU conversion with shares withheld to satisfy tax obligations (a common, routine event), not an open‑market sell driven by the insider. The conversion is recorded as an exercise/conversion of a derivative (standard for RSU vesting); the withholding of shares for taxes is effectively a cashless settlement. No 10b5‑1 plan or other special arrangements were disclosed in the filing.
