(d) Appointment of Directors.

Effective September 29, 2025, the board of directors (the “Board”) of Cantor Equity Partners III, Inc. (the “Company”) appointed Natasha Cornstein as a member of the Board. Ms. Cornstein will serve as a Class I director. Additionally, effective September 29, 2025, the Board appointed Ms. Cornstein as a member of the audit committee of the Board (the “Audit Committee”) and a member of the compensation committee of the Board (the “Compensation Committee”).

Natasha Cornstein is an accomplished executive with over two decades of leadership experience spanning operations, marketing, communications, and digital transformation. As Chief Executive Officer of Blushington Holdings Inc. and its predecessor company (“Blushington”) since 2016, Ms. Cornstein has led teams of over 100, set the strategic vision for the brand, and overseen its evolution from a national brick-and-mortar beauty services business to a cutting-edge, technology-driven beauty education platform and franchise business model. Under her leadership, Blushington successfully expanded its footprint and pioneered new digital strategies. Ms. Cornstein brings deep expertise in brand building, franchising, and omni-channel marketing, and has consistently driven growth through innovation and operational excellence. Ms. Cornstein is a recognized thought leader and passionate advocate for women in business, named a Beauty United Mentor for women of color in 2020 and honored as part of Glossy’s “Glossy 50” in 2020 for leadership in the beauty industry. Prior to Blushington, Ms. Cornstein served as Director of Brand Management at CIRCA (2012–2014), where she led the company’s global rebranding across digital and traditional platforms and represented the brand during its international expansion. From 2003 to 2012, Ms. Cornstein was Vice President of Client Services and Media Relations at Pinnacle Management Corp, a boutique agency representing NBA and international basketball players, where she directed client marketing strategies and high-impact media campaigns. In addition to her executive roles, Ms. Cornstein is the Founder of the Beauty & Wellness Forum, which convened over 100 CEOs across the industry to collaborate during the COVID-19 pandemic. She is also the Co-founder of the Courts of Dreams Foundation, a nonprofit restoring outdoor basketball courts in underserved New York City neighborhoods. Ms. Cornstein also previously served as a director of CF Acquisition Corp. V from January 2021 until consummation of its business combination with Satellogic, Inc. in January 2022 and as a director of CF Acquisition Corp. VII from December 2021 to December 2024 when it liquidated. Ms. Cornstein is a graduate of the CORO Fellows Program in Public Affairs and holds a B.A. in Latin American Studies from Washington University in St. Louis. We believe that Ms. Cornstein is qualified to serve as a member of the Board due to her extensive experience in business management.

In connection with the appointment of Ms. Cornstein, the Board approved the compensation to be paid to Ms. Cornstein for serving as a member of the Board of $50,000 per year, paid quarterly.

There are no family relationships between Ms. Cornstein and any director, executive officer, or person nominated or chosen by the Company to become an executive officer of the Company.
