Audit Committee financial

"Concurrent with her appointment to the Board, Ms. Herubin was appointed to the Board’s Audit Committee"

A company's audit committee is a small group of board members who act like independent inspectors for the firm's finances, overseeing how financial reports are prepared, monitoring internal controls, and managing the relationship with external auditors. Investors care because a strong audit committee reduces the risk of accounting errors, fraud, or misleading statements, making financial statements more trustworthy and helping protect shareholder value.

Corporate Governance Committee regulatory

"including as chair of the Corporate Governance Committee and as a member of the Audit Committee"

A corporate governance committee is a group of board members responsible for defining and overseeing the rules, policies and ethical standards that guide how a company is run, how directors are chosen, and how conflicts are managed. For investors it matters because this committee acts like a referee and coach—shaping leadership choices, enforcing accountability and reducing governance-related risks that can affect trust, reputation and long-term value.

Item 404(a) of Regulation S-K regulatory

"no transactions or relationships between Ms. Herubin and the Company that would be required to be reported under Item 404(a) of Regulation S-K"

Emerging growth company regulatory

"Brandywine Realty Trust Emerging growth company Brandywine Operating Partnership, L.P. 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.
