What Happened

Ryan F. Raber, EVP — Strategy, Sales & Marketing at Mayville Engineering Company, Inc. (MEC), sold 20,000 shares in an open-market transaction on May 26, 2026. The shares were sold at $26.00 per share for a total proceed of $520,000. This was a sale (code S), not a purchase or option exercise.

Key Details

  • Transaction date: 2026-05-26; Price: $26.00 per share; Total proceeds: $520,000.
  • Transaction type: Open-market sale (Form 4 code S).
  • Filing date / timeliness: Report filed 2026-05-27 (period of report 2026-05-26) — appears timely under Form 4 rules.
  • Shares owned after transaction: Not specified in the provided excerpt.
  • Notable footnotes in the filing: F1 notes most recent ESOP/401(k) balance; F2–F5 describe option vesting schedules; F6–F8 describe restricted stock unit (RSU) vesting schedules.
  • No 10b5-1 plan, tax-withholding sale, or gift notation provided in the supplied data.

Context

  • Sales by executives can be routine (diversification, tax or liquidity needs) and do not, by themselves, indicate management’s view of company prospects. This report documents an outright open-market sale rather than an exercise, gift, or award.
  • The filing’s footnotes show the insider has additional equity subject to vesting (options and RSUs), which may impact future transactions but are separate from this sale.
