Board of Directors financial

"notified the Board of Directors (the “Board”) of Allbirds, Inc."

The Board of Directors is a group of people chosen by a company's owners to help make big decisions and oversee how the company is run.

Emerging growth company regulatory

"Emerging growth company"

An emerging growth company is a recently public or smaller public firm that qualifies for temporary, lighter regulatory and disclosure rules to reduce the cost and effort of being public. For investors, it means the company may provide less historical financial detail and face fewer reporting requirements than larger firms, so it can grow more quickly but also carries higher uncertainty—like buying a promising early-stage product with fewer user reviews.

Nasdaq Stock Market LLC financial

"BIRD | The Nasdaq Stock Market LLC"

Nasdaq Stock Market LLC is the company that operates the Nasdaq electronic stock exchange, a large centralized marketplace where shares of publicly traded companies are listed and bought and sold. Think of it as a high-speed digital auction house and storefront combined: being listed there gives a company visibility and easier access to many buyers, while investors benefit from transparent prices, fast trades and regulated rules that help protect fair trading.
