Henry David Philip 4

What Happened

• Henry David Philip, EVP, Global Strategic Marketing & GM, MSD at MKS Inc., had multiple restricted stock units (RSUs) convert to common shares on Feb 17, 2026. As part of the vesting/conversion, 4,097.269 shares were withheld by the company to satisfy tax withholding obligations at $260.74 per share, totaling $1,068,322. The filing also shows a new RSU award of 2,567.126 units (derivative) granted the same day.
• This activity reflects routine vesting and company tax withholding rather than an open-market sale or discretionary trade by the insider.

Key Details

• Transaction date: Feb 17, 2026 (reported Feb 18, 2026).
• Material tax withholding: 4,097.269 shares withheld at $260.74/share = $1,068,322 (coded F = payment of exercise price or tax liability).
• Multiple entries coded M indicate conversion/exercise of derivative awards (RSUs converting to shares); one entry coded A is a grant/award of 2,567.126 RSUs.
• Footnote F1: each RSU = right to one share. F2: shares were withheld by MKS to satisfy tax withholding and do not represent a discretionary sale. Several footnotes (F3–F9) describe vesting schedules and that some RSUs were performance-based with vesting in three equal annual installments.
• Filing appears timely (reported the day after the transaction); no late-filing flag indicated in the provided data.
• Shares owned after the transaction are not disclosed in the supplied summary.

Context

• The M-coded entries here reflect RSU vesting/conversion rather than an outright purchase. The F-coded withholding is essentially a cashless method: the company keeps a portion of the newly issued shares to cover taxes rather than the insider selling shares on the open market.
• For retail investors: this is a routine compensation-related event and not necessarily a signal of insider sentiment. The most relevant datapoint is the ~$1.07M withheld for taxes following RSU vesting.
