Our decision to temporarily suspend activities related to the DOE loan program could adversely affect our access to low-cost capital, delay project execution, and expose us to potential termination or modification of the DOE loan guarantee.

On January 16, 2025, the DOE agreed to arrange a multi-draw term-loan facility to finance the development, construction, and ownership of up to six green-hydrogen production facilities. Our ability to receive advances under the DOE loan remains subject to technical, legal, environmental, and financial conditions and achievement of specific milestones, which may not be achieved when anticipated or at all.

In November 2025, we elected to temporarily suspend activities related to the DOE loan program while we evaluate our optimal reallocation of capital, including projects previously contemplated in New York and Texas. This suspension, although intended to align capital allocation with higher-return opportunities, could cause the DOE to delay, reduce, or withdraw future funding commitments if it determines that project-development conditions are no longer being met or that milestones must be re-established. The DOE loan guarantee contains conditions precedent, milestones, and ongoing covenants that may be impacted by changes in project scope or timing. There can be no assurance that the DOE will consent to modified development plans, or that the loan guarantee will remain available under the same terms following a suspension of activity.

If the DOE determines that we are not meeting required conditions or project milestones, the agency could terminate its loan guarantee commitment. Any such action could limit our ability to finance future hydrogen-generation or infrastructure projects on comparable terms, increase our cost of capital, or cause delays in the development of projects. In addition, suspension of the DOE loan program could be viewed unfavorably by other counterparties, lenders, or strategic partners and could adversely affect our reputation or perceived creditworthiness. While we believe that reallocating capital toward higher-return initiatives represents a prudent financial and strategic decision, these actions may also result in foregone benefits associated with the DOE program, including favorable interest rates and long-term governmental support for hydrogen infrastructure, and our financial condition, liquidity, and ability to execute our growth strategy could be adversely affected.
