Munch Mark 4

What Happened

• Mark Munch, Executive VP & President of Bruker Nano Inc., exercised 2,000 stock options at $22.19 (cost $44,380) on 2026-03-13 and sold 2,000 shares that same day in an open-market sale at $35.44, generating proceeds of $70,880. The transactions produced roughly $26,500 in pre-tax proceeds (sale proceeds minus exercise cost).
• The filing also reports a separate 2,000-share derivative disposition listed with a $0.00 price on the same date (see Key Details and Context below).

Key Details

• Transaction date: March 13, 2026.
• Exercise: 2,000 shares at $22.19 = $44,380 (code M).
• Sale: 2,000 shares at $35.44 = $70,880 (code S). Sale effected pursuant to a Rule 10b5-1 trading plan (footnote F1).
• Additional derivative disposition: 2,000 shares reported at $0.00 (listed as disposed) — shown in the filing but no cash value reported.
• Shares owned after the transactions: not specified in the provided excerpt; see the full Form 4 for post-transaction holdings.
• Filing timeliness: Reported on March 16, 2026 for a March 13 transaction — appears to be filed within the Form 4 timing requirements (not flagged as late).

Context

• Because the exercise and sale occurred the same day, this effectively sold the exercised shares into the market (a common liquidity/cashless-like outcome). The open-market sale was made under a pre-established 10b5-1 plan, which typically schedules sales in advance.
• Footnote F2 notes the related option grant (originally dated Oct 4, 2016) vests over anniversaries of that grant; the exercises reported are tied to vested option rights from that grant.
• These transactions are factual disclosures of insider activity; they do not by themselves indicate the insider’s future view of the company’s prospects.
