FAQ

What insider transaction did COSO director John G. Aldridge Jr report?

John G. Aldridge Jr reported an equity compensation grant of 927 restricted stock units. The RSUs were awarded on 02/11/2026 and represent a grant or other acquisition, not an open-market purchase or sale of CoastalSouth Bancshares common stock.

How many restricted stock units were granted to COSO director Aldridge?

Aldridge received 927 restricted stock units. These RSUs are derivative securities that each convert into one share of CoastalSouth Bancshares common stock, bringing his total beneficially owned derivative securities reported in this filing to 927 units held directly.

When do John G. Aldridge Jr’s COSO RSUs vest?

The 927 restricted stock units granted to Aldridge are scheduled to vest 100% on 12/31/2026. Once vested, each RSU converts into one share of CoastalSouth Bancshares common stock, aligning his compensation with the company’s long-term performance.

Are Aldridge’s COSO restricted stock units directly owned?

Yes. The Form 4 shows the 927 restricted stock units as directly owned. The ownership code is reported as “D” for direct, and there is no footnote indicating indirect ownership through another entity, trust, or family vehicle for these derivative securities.

Does Aldridge’s COSO Form 4 involve an open-market stock trade?

No. The transaction code is “A,” described as a grant, award, or other acquisition. The 927 restricted stock units were granted at a price of $0.0000 per unit, indicating equity compensation rather than an open-market buy or sell of existing common shares.

What does one-for-one conversion mean for COSO restricted stock units?

One-for-one conversion means each RSU becomes one share of CoastalSouth Bancshares common stock upon settlement. For Aldridge’s 927 RSUs, full vesting and conversion would result in 927 shares, directly tying his compensation to the company’s future share performance.
