4 terms

Annual Meeting of Stockholders financial

"he will not stand for re-election to the Company’s Board of Directors at the 2027 Annual Meeting of Stockholders"

Board of Directors financial

"a member of the Board of Directors, of Northern Technologies International Corporation"

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. They act like a team of advisors or managers, making sure the company stays on track and meets its goals. Their choices can influence the company's success and how it grows.

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.

The Nasdaq Stock Market market

"Common stock, par value $0.02 per share | NTIC | The Nasdaq Stock Market"

The Nasdaq Stock Market is an electronic marketplace where investors buy and sell shares of publicly traded companies, often including many technology and growth-oriented firms. It matters because listing there creates a public price, liquidity and regulatory oversight — like a busy public market where buyers and sellers set value — and Nasdaq’s trading systems and listing standards affect how easily investors can trade shares and how companies raise capital.
