[144] Third Coast Bancshares, Inc. SEC Filing

Rhea-AI Filing Summary

Third Coast Bancshares, Inc. (TCBX) – Form 144 filing

An insider has filed a notice to sell 3,000 common shares via Fidelity Brokerage Services on or about 29 July 2025. At the current market value of $110,940, the proposed sale meets Rule 144’s reporting threshold. The shares equal roughly 0.02 % of the 13.83 million shares outstanding. The stock being sold was originally purchased—1,000 shares on 01-Jul-2013 and 2,000 shares on 04-Feb-2017. No other sales by this insider have occurred in the past three months.

The filing does not introduce new dilution; it merely registers the intent to dispose of already issued shares. The signer certifies that no undisclosed material adverse information exists. While the stake is immaterial to float, investors often monitor insider activity; even a modest sale can be interpreted as a short-term sentiment indicator.

Positive

• None.

Negative

• Insider intends to sell 3,000 shares (~$111k), which can be interpreted as a modestly bearish signal despite representing just 0.02 % of shares outstanding.

Insights

Securities Analyst

TL;DR: Small insider sale (<$0.11m, 0.02 % float) – negligible fundamental impact, mild negative sentiment.

The Form 144 discloses a planned disposition of 3,000 TCBX shares. Dollar value is modest and volume far below any level that would pressure liquidity. Because the shares were previously acquired in open-market purchases, the transaction merely transfers ownership and does not dilute existing shareholders. Nevertheless, insider selling—regardless of size—is often viewed cautiously by momentum traders and could weigh on near-term sentiment. From a long-term fundamental perspective, impact is immaterial.
