RSUs financial

"Number of shares includes 109,565 RSUs (excluding the impact of shares"

RSUs, or restricted stock units, are a form of company shares given to employees as part of their compensation. They are typically awarded with certain restrictions, such as a waiting period before they can be fully owned or sold, similar to earning a gift that becomes fully yours over time. For investors, RSUs can impact a company's stock offerings and reflect how much the company relies on stock-based incentives to attract and retain talent.

vesting dates financial

"converted on a one-for-one basis into shares of Cohu, Inc. Common Stock immediately upon the vesting dates"

performance goals financial

"assuming continued service through the vesting dates and achievement of specified performance goals"

Performance goals are specific, measurable targets a company sets for financial results, operational milestones, or individual roles—examples include revenue, profit, production levels, or completion of a project. They matter to investors because meeting or missing these targets influences management pay, future forecasts, deal-related payments and market confidence; think of them as a scoreboard that helps outsiders judge whether the business is performing as promised.
