restricted shares financial

"vesting of a previously reported grant of restricted shares to satisfy the income tax"

Restricted shares are company stock that cannot be sold or transferred immediately because they are subject to legal or contractual limits, such as a required holding period or performance conditions. They matter to investors because these locked-up shares can affect a company’s available stock for trading, future dilution, and insider incentives—imagine a gift that can’t be cashed until certain conditions are met, which changes when and how much supply can suddenly enter the market.

income tax withholding financial

"to satisfy the income tax withholding and remittance obligations of the reporting person"

net settlement price financial

"at a net settlement price equal to closing price on the NASDAQ Global Select Market"

NASDAQ Global Select Market market

"equal to closing price on the NASDAQ Global Select Market on July 21, 2026"

A Nasdaq Global Select Market listing is the highest tier of stocks on the Nasdaq exchange, reserved for companies that meet the strictest financial, reporting and governance standards. For investors, it acts like a premium quality label—signaling larger, more transparent and better-governed companies that tend to offer greater liquidity and lower perceived risk compared with lower-tier listings, making it easier to buy, sell and evaluate shares.
