Stellar Bancorp (STEL) CFO Paul Egge Disposes 68,594 Shares

What Happened

  • Paul P. Egge, Senior Executive VP and Chief Financial Officer of Stellar Bancorp, reported a disposition of 68,594 Stellar shares on July 1, 2026. The Form 4 lists the transaction with a $0.00 per-share price because the shares were cancelled and converted under the merger with Prosperity Bancshares, Inc.
  • Under the merger terms each Stellar share was converted into 0.3803 shares of Prosperity common stock and $11.36 in cash. The 68,594 shares therefore yielded approximately $779,227.84 in cash and about 26,086.3 Prosperity shares (rounded: ~$779.2K cash + ~26,086 Prosperity shares).

Key Details

  • Transaction date: 2026-07-01. Transaction code: D (Disposition to issuer) related to the merger closing (Effective Time).
  • Form 4 shows $0.00 per share (shares were cancelled and converted into merger consideration rather than an open-market sale).
  • Merger consideration per Stellar share: 0.3803 Prosperity shares + $11.36 cash.
  • Cash received (approx): $779,227.84. Prosperity shares received (approx): 26,086.3.
  • Breakdown of the 68,594 converted shares (from footnotes): 38,077 common shares; 10,819 restricted stock awards; 19,698 performance-unit–based awards (6,925 from 2024, 8,202 from 2025, 4,571 from 2026).
  • Performance awards: all performance-unit awards fully vested and converted to cash with performance deemed achieved at 100% of target (except 2024 awards, deemed at 200% of target).
  • Stellar common stock outstanding immediately prior to the Effective Time was cancelled and converted, so Stellar common shares were not held post-closing; this was a corporate-merger conversion rather than a routine insider sale.
  • Filing appears timely (reported with period and filing date of 2026-07-01).

Context

  • This transaction is the result of a corporate merger (Stellar being acquired by Prosperity) and reflects conversion of equity and awards into the agreed merger consideration (cash + Prosperity stock). It is not an open-market trade or an exercised option; restricted and performance awards vested/converted per the merger terms. Such corporate-event dispositions do not necessarily reflect the insider’s personal trading decisions.
