On October 26, 2026, TrueBlue, Inc. (the “Company”) announced the appointment and election of Elizabeth Castro Gulacsy to the Company’s board of directors (the “Board”), effective October 26, 2026. In connection with Ms. Castro Gulacsy’s appointment, the Board increased the size of the Board to ten directors, effective October 26, 2026.

Ms. Castro Gulacsy has served as a director of NNN REIT, Inc. (NYSE: NNN), including on its Audit Committee since 2022 and on its Governance and Nominating Committee since 2026. She is the former Chief Financial Officer and Treasurer of United Parks & Resorts Inc. (NYSE: PRKS) (formerly SeaWorld Entertainment, Inc.

During her tenure from 2013 to 2023, she held finance roles of increasing responsibility, including Chief Accounting Officer, before serving as Chief Financial Officer and Treasurer, a position she held until 2022, when she transitioned to provide CFO consulting and advisory services to the company. During her tenure, she chaired the company’s Disclosure Committee and Enterprise Risk Management Committee and played a key role in the company’s 2013 initial public offering. She also led senior notes offerings, debt amendments, a debt refinancing, and multiple cost-saving initiatives.

Earlier, Ms. Castro Gulacsy spent more than a decade at Cross Country Healthcare, Inc. (formerly Nasdaq: CCRN), a provider of healthcare recruiting, staffing and workforce management solutions, where she rose from Assistant Controller to Chief Accounting Officer and Corporate Controller.
