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 Item 5.02 Departure of Directors or Certain Officers"

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.
