Risks Related to Our Investment in Frontier Power USA
Previous wording
Our minority investment in Frontier Power USA and related commercial arrangements may expose us to new risks and may not achieve the anticipated strategic or financial benefits.
Current wording
Our minority investment in FPUSA and related commercial arrangements may expose us to new risks and may not achieve the anticipated strategic or financial benefits.
Previous wording
Our minority investment in Frontier Power USA represents an expansion of our business model beyond the manufacture and sale of energy storage systems. Frontier Power USA is expected to develop, finance, own and operate long-duration energy storage projects, which may expose us to risks associated with project development, financing, permitting, construction, interconnection, operations, electricity markets, asset ownership, insurance availability, third-party performance and other matters outside our historical business. These risks may be difficult to predict or manage and may be affected by factors outside our control. Because we do not own a controlling interest in Frontier Power USA, we may have limited ability to influence strategic, operational, financing or commercial decisions that could affect the value of our investment or our broader business objectives.
Current wording
Our minority investment in FPUSA represents an expansion of our business model beyond the manufacture and sale of energy storage systems. FPUSA has been formed to develop, finance, own and operate long-duration energy storage projects, which may expose us to risks associated with project development, financing, permitting, construction, interconnection, operations, electricity markets, asset ownership, insurance availability and performance, third-party performance and other matters outside our historical business. These risks may be difficult to predict or manage and may be affected by factors outside our control. Because we do not own a controlling interest in FPUSA, we may have limited ability to influence strategic, operational, financing or commercial decisions that could affect the value of our investment or our broader business objectives.
Previous wording
Frontier Power USA is expected to become a customer of the Company under arms length commercial arrangements. Our future revenues, backlog and growth strategy may therefore be affected, in part, by Frontier Power USA's ability to develop, finance and operate energy storage projects. If Frontier Power USA is unable to execute its business plan, experiences financial or operational challenges, reduces or delays purchases of our products, or otherwise fails to meet expectations, our business, financial condition, results of operations and growth prospects could be adversely affected. We will also need to continue to maintain a diversified customer base and avoid undue reliance on any single customer or commercial relationship.
Current wording
FPUSA is, and is expected to remain, a customer of the Company under arm’s length commercial arrangements, and may also finance or facilitate purchases of our products by project companies, developers and other third parties, either directly or as co-customers with FPUSA. Our future revenues, backlog, customer concentration and growth strategy may therefore be affected, in part, by FPUSA’s ability to develop, finance, construct, own, operate and monetize energy storage projects. If FPUSA is unable to execute its business plan, experiences financial or operational challenges, reduces or delays purchases of our products, or otherwise fails to meet expectations, our business, financial condition, results of operations and growth prospects could be adversely affected. Because FPUSA has represented, and may continue to represent, a significant portion of our backlog or revenues, any such reduction or delay could have a disproportionate effect on our near-term commercial performance. We will also need to continue to maintain a diversified customer base and avoid undue reliance on any single customer or commercial relationship.
Previous wording
As currently constructed, Frontier Power USA will be controlled and managed by a related party. As a result, situations may arise in which the interests of Frontier Power USA, its owners and the Company are not fully aligned with respect to commercial arrangements, governance matters, financing decisions or other business activities. While we expect to work collaboratively with our partners and maintain appropriate governance arrangements, our ability to influence matters affecting Frontier Power USA may be limited and may depend on the nature of our ownership and governance rights from time to time.
Current wording
As currently constructed, FPUSA is controlled and managed by affiliates of Cerberus Capital Management, a related party with other financing and equity relationships with the Company. As a result, situations may arise in which the interests of FPUSA, its owners and the Company are not fully aligned with respect to commercial arrangements, governance matters, financing decisions or other business activities. Although we have governance rights and expect to work collaboratively with our partners, our ability to influence matters affecting FPUSA may be limited and may depend on the nature of our ownership and governance rights from time to time.
Previous wording

This conclusion involves some judgment and will be reassessed periodically, including each reporting period and as relevant facts and circumstances evolve. Changes in Frontier Power USA's business, ownership structure, governance arrangements, financing activities or other factors could result in a different accounting conclusion in the future, which could materially affect our financial statements, reported operating results and financial condition.

Our investment in Frontier Power USA may be difficult to monetize and may result in losses, impairment charges, dilution or other adverse consequences. Our ability to exit or monetize our investment may be limited. In addition, equity financings, warrants, exchange rights or other securities issued or issuable in connection with our investment or related transactions may dilute existing stockholders.
