What Happened

• Joseph H. Griffith IV, Chief Financial Officer of 908 Devices (MASS), settled multiple RSU awards and had a portion of resulting shares sold to cover tax withholding. The Form 4 shows conversions/settlements on Feb 1, 2026 (5,102; 10,306; 11,260; and 43,473 shares) and grant/award entries on Feb 2, 2026 (121,164 and 52,967 RSU-related entries). On Feb 2, 2026 he sold 23,175 shares in the open market at a weighted average price of $6.18 for aggregate proceeds of $143,222 (sales executed at prices ranging $6.105–$6.35).

Key Details

• Transaction dates: Feb 1–2, 2026.
• Sale: 23,175 shares disposed at a weighted average price of $6.18; total proceeds $143,222 (prices ranged $6.105–$6.35). The reporting person can provide detailed per-price breakdown on request (per footnote).
• RSU activity: multiple RSU settlements (reported as exercise/conversion M-type entries) and award/grant entries at $0 reported value (derivative transactions) — these reflect RSU vesting/settlement, not a cash purchase.
• Tax withholding: The sale was a “sell to cover” mandated by the issuer to satisfy tax withholding on the RSU settlement (footnote indicates the sale was not a discretionary open-market trade by the insider).
• Shares owned after transaction: not specified in the provided filing excerpt.
• Filing timeliness: no late-filing flag indicated in the provided details.

Context

• These filings reflect RSU vesting and settlement (footnote: each RSU converts into one share at settlement) and a routine sell-to-cover for required taxes—common when equity awards vest. The derivative entries reported with $0 disposed value reflect RSU settlement/withholding mechanics, not a market sale of those specific lots.
• For retail investors: this is a routine insider action to satisfy taxes on vested awards rather than an independent, discretionary sale signaling a change in outlook.
