Boston and Houston, August 30, 2021 — Ziopharm Oncology, Inc. (“Ziopharm” or the “Company”) (Nasdaq: ZIOP), today announced the appointment of Kevin S.

Mr. Boyle has also been named to the Board. In addition, today the Company has announced promotions within its senior leadership.

Mr. Boyle has over 20 years of experience in leading businesses in competitive and transformative situations and has a strong track record of delivering shareholder value. He is also an accomplished capital markets professional with strong banking relationships cultivated by raising over $2.0 billion in equity and debt capital over his career. Most recently, Mr. Boyle was CEO of Kuur Therapeutics (formerly known as Cell Medica Ltd.), leading the company through a successful transformation, culminating in a $185 million acquisition in May 2021 by Athenex (NASDAQ: ATNX), a global biopharma company focusing on the development and commercialization of cancer therapies.

The appointment of Mr. Boyle and the elevation of roles and responsibilities for select executives continue the Board’s actions to solidify the senior leadership team, move the Company forward and execute on its distinctive cell therapy platform and potentially groundbreaking cancer therapies.

“On behalf of the entire Board of Directors, we welcome Kevin to the Company,” said James Huang, Executive Chairman. “During the robust search process, the Board was pleased to interview a number of very strong candidates. The Board was deliberative, and considered candidates from big pharma to small biotechs, and Kevin rose to the top of the list during the process. Kevin brings tremendous business experience with his operational expertise, strong financial acumen, and an ability to drive disciplined capital allocation. He has a strong track record of successfully guiding companies, both in and out of the biotech sector, through critical periods in their growth trajectories. In particular, his work at Kuur demonstrated his operational expertise in effectively managing a business with capital constraints and demanding timelines. We have the right science and scientific team to deliver, and we are confident that we now have the right person to successfully lead the Company forward towards clinical and business success.”

Mr. Huang continued, “We also sincerely thank Heidi for her commitment to the Company and the outstanding job she has done over the past six months. We look forward to her continued contributions as a dedicated and valued Board member.”

Mr. Boyle said, “I am excited to join the Ziopharm team and am impressed by the extraordinary opportunity that lies ahead. Heidi, the management team and the Board have laid the foundation for Ziopharm to succeed based on its best-in-class science. I understand the challenges ahead and I look forward to working diligently with our dedicated and talented team to unlock our incredible potential as an innovative, world-class oncology company. My priorities will be to deliver shareholder value and to ensure the success of the organization by driving the TCR-T program forward, while seeking and executing validating partnerships across our entire portfolio of scientific assets.”

The Board’s selection of Mr. Boyle was unanimous. The CEO search committee was comprised of Robert Postma, Heidi Hagen and Mary Thistle, with support and guidance from the entire Board.
