HYDROGRAPH ADDS NUCLEAR INDUSTRY EXPERT AND SHAREHOLDER KERRY LANDIS TO ITS BOARD

Hydrograph Clean Power Inc. has appointed nuclear industry expert and Hydrograph shareholder Kerry D. Landis to its board of directors.

Mr. Landis specializes in nuclear safety consulting for the power industry, leveraging more than 40 years of experience as an industry expert and team leader across numerous assessments; as chairman of the Virgil C. Summer Nuclear Safety Review Committee; as member of the San Onofre Nuclear Generating Station Nuclear Oversight Board and the Fort Calhoun Station Safety and Review Committee; and as a senior manager and inspection team leader at the U.S. Nuclear Regulatory Commission (USNRC).

Mr. Landis earned a bachelor of science in chemistry from Western Illinois University and served as a qualified naval nuclear engineer officer with deployments under NATO and U.S. Navy nuclear submarine operations, retiring at the rank of commander.

Additionally, Mr. Landis owns approximately 9.3 million Hydrograph shares and 1.0 million warrants to acquire Hydrograph shares across direct and family accounts, acquired through direct and indirect purchases made since the fall of 2022.

On joining the board, Mr. Landis said: "Hydrograph's graphene stands apart as a proven, consistent and effective additive, delivering measurable commercial benefits across a rapidly growing list of applications in large end-markets. As a longtime shareholder in the business, I'm excited to work with the board and team at Hydrograph to commercialize these applications and realize graphene's full potential as a nanomaterial."

"Kerry brings extensive insight to Hydrograph's operating needs and end markets based on his years in the nuclear and power industry markets. In particular, his background in operational excellence, regulatory requirements, risk assessment and safety protocol will be important resources as we scale. Additionally, he has been a longtime investor in the business based on his detailed research into the unique properties of our graphene, providing an important vantage point as we work to create value for our stockholders," said Hydrograph's chief executive officer, Kjirstin Breure, who was named chair of the board this past June.

In connection with Mr. Landis's appointment, the company also announces that David Morris has resigned as a director, effective Sept. 5, 2025. The board of directors would like to thank Mr. Morris for his contributions to the company.
