What Happened

The filing also shows a simultaneous disposition of those 1,253 shares at $0.00 (no cash proceeds reported).

Key Details

• Transaction date: February 15, 2026.
• Transactions reported: conversion/exercise of 1,253 RSUs (acquired) and disposition of 1,253 shares at $0.00 (disposed); both reported with code M (exercise/conversion of derivative).
• Prices/proceeds: Acquisition listed as N/A; disposition reported at $0.00 (no cash proceeds reported).
• Shares owned after the transaction: not disclosed in the provided filing.
• Footnotes: F1 – each RSU converted one-for-one into a share of common stock. F2 – the RSUs originated from a Feb 15, 2023 grant of 3,684 RSUs vesting in three equal annual installments; the third tranche vested on Feb 15, 2026.
• Filing date/timeliness: Form 4 filed Feb 18, 2026 for a Feb 15 transaction (filed within the typical Form 4 reporting window).

Context

• This was a vesting/conversion of RSUs rather than an open-market buy or typical cash sale. The reported disposition shows $0.00 proceeds (company did not report cash received); filings like this often reflect share conversion and internal disposition mechanics (e.g., withholding), but the Form 4 does not state a cash sale or amount received.
