“NNN has long benefited from a Board of Directors that brings together seasoned public company management, sophisticated backgrounds and expertise, and a proven commitment to creating long-term value for shareholders,” said Edward J.

She began her career as a real estate investment banking analyst on both principal investing and strategic advisory transactions. Ms. Chiu earned a Bachelor of Science in Finance and Accounting, summa cum laude, from NYU Stern School of Business.

Mr. Mueller currently serves as a member of the Board of Trustees of Vivmark Residential, the combined company formed in 2026 through the merger of AvalonBay Communities and Equity Residential, creating the largest publicly traded multifamily apartment REIT in the United States.
