FAQ

What insider transaction did CoastalSouth Bancshares (COSO) report for James S. Macleod?

CoastalSouth Bancshares reported that director James S. Macleod received an award of 1,189 restricted stock units on February 11, 2026. These RSUs represent a form of equity compensation rather than an open-market purchase or sale of the company’s common stock.

How many restricted stock units did the COSO director receive in this Form 4 filing?

The director received 1,189 restricted stock units. This entire amount was reported as acquired in a single transaction and matches the total number of derivative securities beneficially owned following the transaction, indicating this filing reflects the full grant.

When do the CoastalSouth Bancshares (COSO) RSUs granted to James S. Macleod vest?

The RSUs granted to James S. Macleod vest 100% on December 31, 2026. Vesting means the units fully become his, and after vesting they can convert into an equal number of CoastalSouth Bancshares common shares on a one-for-one basis.

What does one-for-one conversion of COSO restricted stock units mean in this filing?

One-for-one conversion means each restricted stock unit turns into one share of CoastalSouth Bancshares common stock. For this grant, 1,189 RSUs can ultimately become 1,189 common shares once they are vested and settled according to the award’s terms.

Was the insider COSO transaction a purchase or a grant of equity?

The transaction was a grant or award of equity, not a market purchase. The Form 4 uses transaction code “A” for acquisition and describes the RSUs as a grant, with a reported price per unit of 0.0000, indicating a compensation-related award.

How is ownership reported for the RSUs in the COSO Form 4?

Ownership for these RSUs is reported as direct. After the February 11, 2026 grant of 1,189 restricted stock units, the Form 4 shows James S. Macleod directly and beneficially owning 1,189 derivative securities tied to CoastalSouth Bancshares common stock.
