[Form 4] Southside Bancshares, Inc. Insider Trading Activity

Rhea-AI Filing Summary

Susan Elaine Anderson, a director of Southside Bancshares, Inc. (SBSI), received 15 shares on 09/04/2025 as dividend equivalent rights tied to restricted stock units (RSUs). The shares were issued at $0 as part of a cash dividend treatment and increased Ms. Anderson's direct beneficial ownership to 11,470 shares. The filing also reports indirect holdings of 23,143 shares (spousal IRA) and 681 shares (IRA). The Form 4 was signed by an attorney-in-fact on 09/08/2025. The disclosure reflects a routine equity issuance tied to compensation/dividend mechanics rather than an open-market purchase or sale.

Insights

Financial Analyst

TL;DR: Small issuance of 15 dividend-equivalent shares minimally alters ownership; no cash consideration and no market trade reported.

The transaction is a non-cash issuance of 15 shares as dividend equivalents on RSUs, which increases the reporting person’s direct stake to 11,470 shares while significant indirect holdings remain in retirement accounts. Because the shares were issued at $0 and arise from compensation/dividend mechanics, this filing is unlikely to affect short-term market valuation or signal a change in insider conviction. Materiality is low given the small number of shares relative to typical institutional positions.

Corporate Governance Expert

TL;DR: Routine equity compensation event for a director; disclosure complies with Section 16 reporting requirements.

This Form 4 documents the reporting of dividend-equivalent rights converted to common stock underlying RSUs. The filing identifies the reporting person as a director and discloses direct and indirect ownership breakdowns, including spousal IRA and personal IRA holdings. The signature by an attorney-in-fact and the explanatory remark clarify the non-market nature of the transaction. From a governance standpoint, the filing is standard and presents no control or related-party concerns.
