"These shares were acquired pursuant to the vesting of performance share units (PSUs)."

total shareholder return (TSR) financial

"total shareholder return (TSR) relative to the other companies in the Russell 3000 index"

Total shareholder return (TSR) measures how much an investment in a company's stock has grown over a specific period by combining the change in the share price and all dividends paid, expressed as a percentage. Think of it like tracking the total balance of a savings jar that increases both from added cash (dividends) and a rising sticker price on the jar (share price); investors use TSR to compare how well different stocks or managers deliver real, money-in-hand returns.

Russell 3000 index financial

"TSR relative to the other companies in the Russell 3000 index"

A broad stock market index that tracks the performance of the roughly 3,000 largest publicly traded U.S. companies by total market value, representing almost the entire U.S. equity market. Investors use it like a big basket or thermometer: it provides a simple snapshot of overall U.S. stock market health, serves as a benchmark for funds and portfolios, and helps measure diversification, risk and returns over time.

non-GAAP operating income financial

"based on Logitech's average revenue growth in constant currency, non-GAAP operating income, total shareholder return"

Non-GAAP operating income is a measure of a company's profit from its core business activities, calculated by excluding certain expenses or income that are not part of regular operations. It provides a clearer picture of how well the business is performing by focusing on ongoing operations, helping investors compare companies more consistently and make better-informed decisions.
