Our risk factors are disclosed in Part I, Item 1A of our 2024 Annual Report. [Other than as described below, there have been no material changes from our updates to the risk factors discussed in Part I, Item 1A. Risk Factors, of our 2024 Annual Report as updated in our Quarterly Reports on Form 10-Q for the fiscal quarters ended March 31, 2025 and June 30, 2025.

An extended U.S. Government shutdown could materially adversely affect our business, results of operations, and financial condition.

A portion of our revenue is linked to projects supported directly or indirectly by U.S. government programs, including those administered by the Department of Energy (DOE). The U.S. continues to face a changing geopolitical environment, along with certain fiscal and economic challenges, and uncertainty exists regarding how future budget and program decisions will unfold. During periods of federal government shutdowns, many government agencies and contracting offices cease operations or operate at reduced capacity. These shutdowns may delay funding decisions, new contract awards, contract modifications, and may result in the suspension of ongoing work under existing contracts.

In the event of a prolonged federal government shutdown, we may experience delays in critical DOE-dependent project milestones. This could include:

•Postponed disbursement of grants or cooperative agreements;

•Slower progression through loan guarantee processes; and

•Financing bottlenecks for cost-share projects reliant on DOE commitments.

Such delays could shift expected revenue recognition from project services, equipment sales, or offtake-linked products, particularly for projects in earlier cohorts where DOE involvement plays a catalytic role.

Government shutdowns can also create uncertainty in federal budgeting and procurement priorities, which could reduce future opportunities for our products. We continue to actively manage this risk by seeking to diversify our project funding sources, engage private capital partners, and sequence project cohorts to mitigate dependency. Nonetheless, these efforts may not be successful, and prolonged government funding disruptions could negatively impact the timing of certain revenue streams and increase working capital pressure in the near term.

The timing and duration of any shutdown are unpredictable, and we cannot estimate the ultimate effect on our business. Any prolonged or repeated shutdowns could have a material adverse effect on our financial condition, results of operations, and ability to execute our strategic objectives.
