Key Details

• Transaction date: 2026-07-01 (Disposition to issuer, code D); Form 4 filed same day.
• Form 4 shows price per share: $0.00 (reflects conversion/cancellation, not an open-market sale).
• Merger consideration per share (Footnote F1): 0.3803 Prosperity shares + $11.36 cash.
• Total consideration for 2,230 shares: $25,332.80 cash + ~848.07 Prosperity shares.
• Shares owned after transaction: not specified in the filing.
• No 10b5-1, tax-withholding, or late-filing notes were reported.

Context This was a corporate merger-related conversion (Stellar merged into Prosperity) rather than an open-market sale by the insider. The filing documents the mechanical conversion of Stellar shares into cash and Prosperity stock under the merger agreement and should be read as a transaction tied to that corporate event, not necessarily an indicator of the director’s market view.
