Jacqueline F. Moloney, a member of the board of directors at MKS Inc (NASDAQ: MKSI), completed a sale of 340.107 shares of the companys common stock on March 12, 2026, according to a Form 4 filed with the Securities and Exchange Commission. The shares were disposed of at a weighted average price of $213.7717 per share, producing a total transaction value of $72,705.
The trades that made up the overall sale were executed in multiple transactions, with execution prices ranging from $213.7716 to $214.015. After the transaction, Moloney is recorded as holding 10,393.197 shares of MKS Inc directly.
On the corporate results front, MKS Instruments reported fourth-quarter earnings per share of $2.47, narrowly surpassing the consensus estimate of $2.46. Quarterly revenue came in at $1.03 billion, above the consensus projection of $995.32 million and KeyBancs internal forecast of $1,005 million. The reported revenue figure represents a 10.5% increase compared with the same quarter a year earlier.
Management also provided first-quarter revenue guidance that exceeded market expectations. That guidance was highlighted by Needham as a factor in its decision to raise its price target for MKS Instruments to $300 while maintaining a Buy rating. KeyBanc reiterated an Overweight rating and set a $250 price target in response to the companies strong quarterly performance.
Despite the earnings beat and encouraging guidance, MKS Instruments shares fell 7.3% in after-hours trading following the announcement. The companys Electronics & Packaging segment and its Semi division were cited as continued sources of strength contributing to the overall positive financial showing for the quarter.
Taken together, the disclosed director sale and the companies recent financial results provide a mixed set of datapoints for investors. The Form 4 filing documents the precise terms of the director sale, while the quarterly report and guidance updates have drawn affirmations from several research analysts even as the market reacted negatively in after-hours trading.
Where additional context is limited in public filings and announcements, the record in the Form 4 and the companies earnings release remain the primary sources for the transactions and performance metrics reported here.
