"grant of restricted stock units (RSUs)"

Restricted stock units (RSUs) are a type of company promise to give employees shares of stock in the future, usually after certain conditions like working for a set time. They are like a gift promised today that you receive later, which can become valuable if the company's stock price goes up. RSUs matter because they are a way companies reward employees and can be a significant part of compensation.

"WD-40 Company Profit Sharing / 401(k) Plan account"

A 401(k) plan is a workplace retirement account that lets employees set aside part of their pay into a tax-advantaged savings pot, often with employers adding matching contributions — like a workplace piggy bank for future income. It matters to investors because the amount people save and how employers fund these plans influence consumer spending, corporate payroll costs and the flow of money into financial markets, which can affect stock prices and company valuations.
