Knopp Kevin J. 4

What Happened

• Kevin J. Knopp, President, CEO and Director of 908 Devices (MASS), had multiple derivative instruments (RSUs/options) convert/settle into shares on Feb 1–2, 2026, totaling 404,020 shares acquired through exercises/conversions and RSU settlements.
• On Feb 2, 2026 he sold 34,764 shares in the open market at a weighted average price of $6.18 for aggregate proceeds of $214,842. The sale was a mandatory "sell-to-cover" to satisfy tax withholding obligations related to the RSU settlements.

Key Details

• Dates: conversions/settlements reported Feb 1–2, 2026; Form 4 filed Feb 3, 2026 (appears timely).
• Shares acquired (via exercise/conversion and RSU settlement): 404,020 total (11,255; 13,449; 17,007; 66,288; 205,978; 90,043).
• Shares sold: 34,764 at a weighted average price of $6.18, proceeds $214,842 (sale prices ranged $6.105–$6.32).
• Net increase from these transactions (acquisitions minus sell-to-cover): +369,256 shares. (The Form 4 did not disclose a prior total holdings in the provided data.)
• Notable footnotes: RSU settlements represent one share per RSU at vesting (F1). The sale was mandatory to cover tax withholding (sell-to-cover) and not a discretionary sale by the reporting person (F2). Price reported is weighted average; full price breakdown available on request (F3). Several RSU/option awards have multi‑year vesting schedules (F5–F10). Some shares are held in an irrevocable trust that the reporting person may be deemed to beneficially own (F4).

Context

• These transactions mainly reflect scheduled vesting/settlement of RSUs/options and a routine sell-to-cover for taxes. Derivative entries labeled "exercise/conversion" indicate conversion of vested rights into common shares; the subsequent sale was a tax-related disposal, not necessarily a signal of investment intent.
