*Adrian Zuckerman From Left to Right* 

New York, NY — Hadron Energy, Inc. ("Hadron") proudly announces the designated nominees for its seven-member Board of Directors (BOD), a leadership body composed of some of the most accomplished figures in nuclear energy, public policy, advanced technology, regulatory governance, and public-company operations. Designated ahead of Hadron's proposed $1.2 billion public listing through its definitive business combination with GigCapital7 Corp. (Nasdaq: GIG), the BOD brings together unmatched expertise essential for guiding America's next generation of nuclear deployment.

This distinguished BOD represents a rare concentration of experience: former U.S. diplomatic leadership, decades of NRC executive oversight, global nuclear project development, semiconductor and advanced-technology public-company building, Fortune 500 operational and financial governance, and deep entrepreneurial execution within critical infrastructure markets. Collectively, these directors strengthen Hadron's position as it advances the Halo Micro-Modular Reactor toward commercial deployment, supporting the surging energy demands of data centers, industrial facilities, and national security installations.

------

The BOD of the future public Hadron will comprise of the following members that will serve on the various BOD committees noted below:

**Dr. Avi Katz – As an Independent Director, Executive Chairman of the BOD, and member of the Compensation and Nominating and Corporate Governance Committees** 

Founder and Managing Partner of GigCapital Global, a serial issuer of Private-to-Public Equity (PPE)<sup>™</sup> companies, one of the most experienced technology and public-company builders in the sector, with more than 35 years leading semiconductor and TMT innovation, and fourteen successful Nasdaq and NYSE listings. A Ph.D. in Materials Engineering, a former operating private and public company C-suite executive in various roles with more than 25 years entrepreneurial private and public company Chief Executive Officer and Chairman of the Board experience, which brings unmatched expertise in public-company formation, capital markets, governance, and long-term strategic scaling.

**Ambassador Adrian Zuckerman – As an Independent BOD member, Chair of the Nominating and Corporate Governance Committee, and member of the Compensation Committee** 

Former U.S. Ambassador to Romania between the years of 2018 and 2020, and a seasoned international attorney known for advancing U.S. energy security, foreign investment, and rule-of-law reforms. With decades of legal and policy leadership at the intersection of government, global commerce, and infrastructure, he brings strategic geopolitical insight and strong governance expertise to Hadron's BOD.

**Robert Lewis – As an Independent BOD member, member of the Nominating and Corporate Governance and the Audit Committees** 

Past senior NRC executive with 32 years of leadership in nuclear safety, security, and emergency preparedness. As NRC Deputy Executive Director for Operations, he oversaw nuclear materials, fuel cycle, waste management, rulemaking, and environmental programs, shaping post-Fukushima reforms and major regulatory modernizations. He now advises industry on licensing and regulatory strategy.

**Bryan Timm – As an Independent BOD member, Chair of the Audit Committee and member of the Compensation Committee** 

Veteran public-company operator and board leader with deep expertise in audit, finance, and large-scale operational transformation. He spent 20 years at Columbia Sportswear (Nasdaq: COLM) as President, COO, and CFO and served nearly two decades on the Umpqua Holdings (Nasdaq: UMPQ) board as Vice Chairman of the Board and Audit Committee Chair. He currently chairs the Audit Committee of GigCapital8 (Nasdaq: GIW) and brings strong capital-markets, governance, and financial-oversight experience to Hadron.

**Dr. Raluca Dinu – As an Independent BOD member, Chair of the Compensation Committee and member of the Nominating and Corporate Governance Committee** 

Semiconductor industry executive and Chief Executive Officer of QT Imaging Holdings (OTCQB:QTIH) with a track record of driving global operations, manufacturing excellence, and cross-border technology integrations. As a Managing Partner at GigCapital Global and former senior executive at IDT International, Renesas and GigPeak/GigOptix, she brings deep operational rigor, compensation-design expertise, and public-company transactional experience to Hadron's board.

**Ralph Hunter – As an Independent BOD member, member of the Audit and Nominating and Corporate Governance Committees** 

Globally recognized nuclear-industry executive with 35 years of leadership across SMR development, international nuclear projects, and major utility operations. He has served as CEO of Orion Nuclear, President of Constellation Generation Development, Executive Vice President of JExel Nuclear, and a Board Director of Rolls-Royce SMR. He currently leads RC Nuclear Consultants, advising data centers, investors, and developers on licensing, siting, and new-nuclear deployment.

**Samuel Gibson – As a Non-Independent BOD member and Chief Executive Officer** 

Founder & CEO of Hadron and the visionary behind the Hadron Halo Micro-Modular Reactor. He leads the company's technology development, licensing strategy, commercialization efforts, and growth across the data-center, industrial, and defense sectors. Under his leadership, Hadron entered into a business combination agreement with GigCapital7 to deSPAC in a $1.2B business combination with GigCapital7 and is advancing to become the first publicly traded light-water micro-modular reactor (MMR) company.

"Our Board represents the strongest cross-section of relevant experiences for leading a company in the U.S. nuclear and clean-energy sector today," said Samuel Gibson, Founder and Chief Executive Officer of Hadron. "Each director brings unmatched operational, regulatory, government or financial expertise that will guide Hadron through its transition to the public markets and accelerate the commercial deployment of the Halo Micro-Modular Reactor across data centers, industrial facilities, and critical infrastructure."

Hadron's designation of its BOD composition follows its recently announced $1.2 billion definitive business combination agreement with GigCapital7 Corp. (Nasdaq: GIG), and supports the positioning of Hadron to become the world's first publicly traded light-water MMR company. Achieving this milestone reinforces Hadron's positioning at the forefront of the U.S. nuclear industry.
