What does MKSI's Form 144 report?

It reports a proposed sale of common stock by an affiliate under Rule 144. The excerpt lists multiple stock-grant line items with dates and share counts, indicating intended resale activity rather than a company-initiated offering.

How many shares are shown in the excerpt for MKSI?

The excerpt lists specific grant-related quantities including 10,979; 4,269; and 4,748 shares. It also contains a separate line showing 20,000 beside common stock; the filing lists dates tied to each grant entry.

Do the entries show when the shares were granted or sold?

The lines include grant dates such as 02/15/2020, 07/02/2020, 05/10/2021, 05/09/2022, 02/15/2018, and 02/15/2019. The form lists these dates alongside each stock-grant entry rather than confirming completed sales in the excerpt.

Does the excerpt state prior sales in the past three months for MKSI?

A heading for "Securities Sold During The Past 3 Months" appears, but no numeric totals are shown in the provided excerpt. The filing excerpt therefore lists proposed resale activity and grant details without completed three-month sale totals.
