Key Terms

6 terms

Non-Employee Director Compensation Policy financial

"In accordance with the Company’s Non-Employee Director Compensation Policy (the “Policy”), as a non-employee director..."

Equity Incentive Plan financial

"Dr. Gormley was granted an option under the Company’s 2026 Equity Incentive Plan (the “Plan”) to purchase up to 37,866 shares..."

An equity incentive plan is a program that gives employees, executives or directors the right to receive company stock or options to buy stock as part of their pay. Think of it as offering slices of future company profit to motivate people to boost long‑term performance; for investors it matters because it can align employee goals with shareholder value but also increases the number of shares outstanding, which can dilute existing ownership.

Science and Technology Committee financial

"appointed to the newly created Science and Technology Committee of the Board (the “Science and Technology Committee”) to serve as Co-Chairperson..."

indemnification agreement regulatory

"The Company also entered into an indemnification agreement with Dr. Gormley in the same form as its standard form of indemnification agreement."

An indemnification agreement is a contract in which one party promises to cover losses, costs, or legal claims that another party might face, acting like a tailored safety net or private insurance policy. For investors, it matters because such agreements shift potential financial risk away from a company or its officers and onto the indemnifier, which can affect a company’s future liabilities, cash flow and how risky the investment appears during deal-making or litigation.

forward looking statements regulatory

"This press release contains forward looking statements within the meaning of Section 27A of the Securities Act of 1933..."

Statements about a company’s expected future performance, plans, goals, or projections that are not historical facts and involve assumptions and estimates. Investors care because these are predictions that guide decisions but can be wrong; like a weather forecast, they help set expectations and risk — if circumstances change, actual results may differ significantly, so investors should weigh them alongside hard data and risk factors.

miniprotein radioconjugate platform technical

"Aktis has developed a proprietary, isotope-agnostic miniprotein radioconjugate platform to selectively deliver the tumor-killing properties of radioisotopes..."

Aktis Oncology Appoints Industry Research and Development Veteran Glenn Gormley, MD, PhD to its Board of Directors

BOSTON – April 16, 2026 – Aktis Oncology, Inc. (NASDAQ:AKTS) (the “Company”), a clinical-stage oncology company focused on expanding the breakthrough potential of targeted radiopharmaceuticals to large populations, including those not addressed by existing platform technologies, today announced the appointment of Glenn Gormley, MD, PhD, as an independent director to its Board of Directors and co-chair of the Company’s newly established Science and Technology Committee of the Board of Directors.

“We are delighted to welcome Glenn to our Board as we continue to make significant progress toward upcoming clinical and corporate milestones,” said Matthew Roden, PhD, President and Chief Executive Officer of Aktis Oncology. “Glenn brings deep expertise in global biopharmaceutical leadership and oncology innovation, having guided several blockbuster medicines to approval. In particular, Glenn’s instrumental role in leading the discovery and development of a new generation of optimized, novel antibody drug conjugate (ADC) formats, which created an inflection point in the ADC field, is highly relevant to our vision of broadening the impact of targeted radiopharmaceuticals to large patient populations in need of new treatment options.”

“I am thrilled to work with the Aktis Board and leadership team as the Company continues to gain momentum in broadening the reach and unique benefits of targeted radiopharmaceuticals for patients,” said Dr. Gormley. “I am impressed not only by Aktis’ novel miniprotein radioconjugate platform, but also by its robust end-to-end supply chain to ensure reliability and scalability of product delivery, which I see as key differentiators for Aktis as a next-generation radiopharmaceuticals leader.”

Dr. Gormley brings more than three decades of biopharmaceutical leadership across research and development, executive leadership, and board service. Most recently, Dr. Gormley served as Senior Executive Officer and Global Head of Research and Development at Daiichi Sankyo Co., Ltd., and as Executive Chairman and President of Daiichi Sankyo, Inc. In these roles, he led the global R&D strategy and oversaw the development of a broad and diversified pipeline, including the successful build-out of Daiichi Sankyo’s ADC platform. Prior to Daiichi Sankyo, Dr. Gormley held senior leadership positions at several global pharmaceutical companies. He served as Chief Medical Officer at AstraZeneca and as Global Head of Clinical Development and Medical Affairs at Novartis, where he led late-stage development and medical strategy across multiple programs. Earlier in his career, he held senior clinical development roles at Merck. Dr. Gormley holds an MD and a PhD from the University of Chicago and completed his training at UCLA and New York University leading to board certification in pediatrics and pediatric endocrinology.

Concurrent with Dr. Gormley’s appointment to Aktis’ Board of Directors, current Board members Helen Kim and Oleg Nodelman plan to step down from Aktis’ Board of Directors, effective May 20, 2026.

“On behalf of the Board, I would like to thank Helen and Oleg for their commitment to Aktis from our earliest days as Series A investors and through our transition to a clinical-stage, publicly traded company,” said Todd Foley, Co-Founder and Chairman of Aktis Oncology. “We are deeply grateful for their five years of service, which helped us establish a strong foundation for the Company and shape our ambitious strategy and vision for the future.”

About Aktis’ miniprotein radioconjugate platform

Aktis has developed a proprietary, isotope-agnostic miniprotein radioconjugate platform to selectively deliver the tumor-killing properties of radioisotopes to targeted tumors. Aktis’ therapeutic miniprotein radioconjugates are designed to maximize anti-cancer activity through high tumor penetration coupled with internalization and retention in cancer cells, while rapidly clearing from normal organs and tissues. The Aktis platform further enables clinicians to visualize and verify target engagement with imaging isotopes prior to exposure to therapeutic radioisotopes. Leveraging this platform, and its patient-first end-to-end supply chain, Aktis is advancing a pipeline of next-generation targeted radiopharmaceuticals to address the unmet needs of patients across a broad spectrum of solid tumors.

About Aktis Oncology

Aktis Oncology, Inc. is a clinical-stage oncology company focused on expanding the breakthrough potential of targeted radiopharmaceuticals to large patient populations, including those not addressed by existing platform technologies. Aktis’ most advanced pipeline program, AKY-1189, is a miniprotein radioconjugate targeting Nectin-4, with multi-indication potential across multiple tumor types, including locally advanced or metastatic urothelial cancer, breast cancer, non-small cell lung cancer, colorectal cancer, cervical cancer, and head and neck cancer. Aktis’ second pipeline program, AKY-2519, is a miniprotein radioconjugate targeting B7-H3 expressing tumors, including prostate, lung and other solid tumors. Aktis has a strategic collaboration with Eli Lilly and Company to leverage its miniprotein platform to develop novel radioconjugates outside of Aktis’ proprietary pipeline.
