Strategic case

Why Frontier Power USA, and why now.

With interconnection secured and offtake agreements locked, customers are ready to deploy projects, and Frontier Power USA is expected to enable faster execution by shortening the project lifecycle from commitment to first energy cycle. As an independent entity, Frontier Power USA separates project-level capital from the Eos corporate balance sheet.

Important facts

What shareholders need to know

Annual meeting

The annual meeting vote authorizes an increase in authorized shares of common stock, among other matters. It does not commit any individual shareholder to participate in any offering. Voting is per the proxy materials, typically through your broker. Broker deadlines are usually a few days before the official deadline.

The rights offering

Eligible shareholders receive rights based on existing ownership. Each right would entitle the holder to buy a specified number of new securities at the subscription price. Three options: exercise, sell rights on the market, or let lapse.

Ownership

Non-participating shareholders are expected to experience an additional reduction as unsubscribed shares are absorbed by other participants. Dilution figures move modestly with share price; the directional structure (small for participants, larger for non-participants) holds across scenarios.

Why this raise is different

Prior raises funded manufacturing, technology, and product development. They delivered—the technology works, the factory is running, customers are advancing projects. This is expected to raise funds dedicated to project capital that is expected to convert that capability into deployed assets. The pro rata structure is also different: it is specifically designed to give existing shareholders the first opportunity on equal and advantaged terms.
