Form 144 regulatory

"Filer Information | | | 144: Filer Information"

Form 144 is a document that investors must file with the government when they plan to sell a large number of shares of a company's stock. It helps ensure transparency so everyone knows how many shares are being sold and when, which can impact the stock's price.

cashless financial

"02/15/2019 | Stock grant | MKS Inc. | | | 20000 | 02/15/2019 | Cashless"

A cashless transaction is any deal settled without exchanging physical money; value is transferred by swapping or adjusting securities, like shares or options, rather than paying cash. For investors this matters because cashless settlements preserve a company’s cash balance but can change share counts or ownership percentages, affecting dilution, earnings per share and the value of holdings—similar to trading goods for goods instead of using cash at checkout.

stock grant financial

"02/15/2019 | Stock grant | MKS Inc."

A stock grant is an award of company shares given to an individual, often as part of compensation for employees or executives. It matters to investors because grants can change the number of shares outstanding (dilution) and signal how company leaders are being paid and motivated—think of it like receiving a slice of the company as part of your paycheck, which can affect ownership and future share supply.
