Key Details

• Transaction date: March 24, 2026; Form 4 filed March 26, 2026.
• Acquired: 3,026 shares at $11.20/share — total cost $33,891 (code M: option exercise/conversion).
• Disposed: 3,026 derivative instruments at $0.00 (code M) — represents cancellation of the exercised options.
• Shares owned after transaction: not specified in the provided excerpt.
• Footnote: the option became fully vested and exercisable as of July 21, 2017.
• Remarks: Exhibit 24 (Power of Attorney) attached to the filing.
• Filing timeliness: transaction dated Mar 24, filed Mar 26 — appears timely (within the typical two-business-day Form 4 window).

Context

• This was an option exercise (insider paid the strike price to receive shares). The separate “disposed” line at $0.00 is standard when options are cancelled upon exercise and does not indicate a market sale of the acquired shares.
• No immediate sale is reported here, so this filing signals acquisition of shares rather than a sell-off. Purchases or exercises are generally considered more informative than sales, but this report alone does not indicate the insider’s motive.
