NORTHBOROUGH, Mass., Oct. 16, 2024 /PRNewswire/ -- Aspen Aerogels, Inc. (NYSE: ASPN) ("Aspen" or the "Company"), a technology leader in sustainability and electrification solutions, today announced that it has received a conditional commitment from the U.S. Department of Energy ("DOE") for a proposed loan of up to $670.6 million (the "Loan") under the Advanced Technology Vehicles Manufacturing loan program within DOE's Loan Programs Office ("LPO") for financing the construction of its planned second aerogel manufacturing facility ("Register Plant") in Register, Georgia. The Company also announced Q3 2024 preliminary financial results and details regarding its planned Q3 earnings conference call.

Loan and Project Highlights:

• Aspen Aerogels Georgia, LLC, a subsidiary of Aspen Aerogels, Inc., is the intended borrower of the loan. The loan would be structured as project financing, providing for repayment commencing upon project commissioning.
• The interest rate will be the applicable U.S. Treasury Rate at the time of each cash draw.
• The Register Plant is designed to manufacture PyroThin® aerogel blankets. Aspen's PyroThin platform offers ultrathin and lightweight thermal barriers designed to help prevent thermal runaway propagation - an event in which a battery cell overheats and triggers neighboring cells, possibly resulting in a sudden fire - in batteries. Aspen's PyroThin is designed to offer a unique combination of thermal management, mechanical performance, and fire protection properties. Aerogel thermal barriers have the potential to increase energy density of EV battery systems when compared to alternative thermal barrier products.
• The Register Plant has an initial estimated revenue capacity of $1.2B - $1.6B, depending on product mix.
• The Register Plant project is expected to create up to 550 construction jobs and 255 permanent, full-time operations jobs.
• The project aligns with the LPO's mission of supporting U.S. manufacturing that will help enable the growth of zero-emissions vehicles.

"With this Conditional Commitment, we are pleased to announce that the proposed loan would fully fund the required CAPEX for our second aerogel manufacturing facility, which is expected to play a key role in scaling our PyroThin supply for our rapidly growing Thermal Barrier business," noted Donald R. Young, Aspen's President and CEO. "We believe that PyroThin, which can enable increased battery safety and performance, is a unique and differentiated product that solves an important and challenging problem. The past 12 months have further validated these beliefs; we have increased our revenues to $232 million in this segment, a 277% year-over-year increase¹; secured additional EV production contracts, bringing us to a total of six major OEMs in the United States and Europe; and, won a prestigious Automotive News Pace Award. We are also excited to further DOE's mission to onshore and re-shore domestic manufacturing technologies that are critical to meeting the current federal goal of having half of all new vehicles sold in 2030 be zero-emissions vehicles. We want to thank the DOE Loan Programs Office for its continued support and partnership throughout this process."

Ricardo C. Rodriguez, Aspen's Chief Financial Officer and Treasurer added, "Securing the lowest cost of capital has been the top priority of our financing strategy. This proposed loan, and its terms, will provide us, if finalized, with the opportunity to optimize our capital structure and capture the long-term opportunity that is in front of us. In the meantime, we'll continue maximizing our existing assets and resources to drive profitability."

While this conditional commitment indicates the DOE's intent to finance the project, the DOE and the Company must satisfy certain technical, legal, environmental, and financial conditions before the DOE enters into definitive financing documents and funds the loan.

Non-GAAP Financial Measures

In addition to providing financial measurements based on generally accepted accounting principles in the United States of America ("GAAP"), Aspen provides an additional financial metric that is not prepared in accordance with GAAP ("non-GAAP"). The non-GAAP financial measure included in this press release is Adjusted EBITDA. Management uses this non-GAAP financial measure, in addition to GAAP financial measures, as a measure of operating performance because the non-GAAP financial measure does not include the impact of items that management does not consider indicative of Aspen's core operating performance. In addition, management uses Adjusted EBITDA (i) for planning purposes, including the preparation of Aspen's annual operating budget, (ii) to allocate resources to enhance the financial performance of its business, and (iii) as a performance measure under its bonus plan.

Management believes that this non-GAAP financial measure reflects Aspen's ongoing business in a manner that allows for meaningful comparisons and analysis of trends in its business, as it excludes expenses and gains not reflective of Aspen's ongoing operating results or that may be infrequent and/or unusual in nature. Management also believes that this non-GAAP financial measures provides useful information to investors in understanding and evaluating Aspen's operating results and future prospects in the same manner as management and in comparing financial results across accounting periods and to those of peer companies. This non-GAAP measure may not be comparable to similarly titled measures presented by other companies.

The non-GAAP financial measure does not replace the presentation of Aspen's GAAP financial results and should only be used as a supplement to, not as a substitute for, Aspen's financial results presented in accordance with GAAP. In this press release, Aspen has provided a reconciliation of Adjusted EBITDA to net income (loss), the most directly comparable GAAP financial measure. Management strongly encourages investors to review Aspen's financial statements and publicly filed reports in their entirety and not rely on any single financial measure.
