Christen Timothy L 4

What Happened

• Timothy L. Christen, a director of Mayville Engineering Company, converted/exercised 12,397 derivative shares (form code M) on April 21, 2026 and a matching disposition of 12,397 derivative shares is reported the same date. He also acquired 7,150 shares via a grant/award (form code A). All reported transactions show a $0.00 per-share price. Net effect reported in the filing is an increase of 7,150 shares (12,397 acquired then 12,397 disposed, plus 7,150 awarded).
• These entries indicate conversion/vesting activity rather than an open-market cash purchase or sale. The filing does not show cash value for the transactions.

Key Details

• Transaction date: 2026-04-21; Form 4 filed: 2026-04-23 (timely within the usual 2-business-day window).
• Reported items: M — 12,397 shares exercised/converted (acquired) and 12,397 shares disposed (derivative); A — 7,150 shares granted/awarded (acquired). Price per share reported: $0.00.
• Net share change from these entries: +7,150 shares. The filing does not state the total shares owned after these transactions.
• Footnotes: F1/F2 indicate these were restricted stock units that vest 100% after one year or at the earlier of one year or the next annual shareholder meeting.
• Filing gives no explanation for the contemporaneous disposition (e.g., sale vs. transfer for tax withholding), and no 10b5-1 or other sale-plan is listed.

Context

• For retail investors: awards/RSU vesting and derivative conversions are routine forms of insider compensation and do not necessarily indicate an intent to buy or sell stock on the market. The conversion plus immediate disposition pattern often reflects tax withholding or settlement mechanics, but the filing does not specify the reason.
• This report documents internal compensation/vesting activity rather than an open-market purchase or strategic sale.
