• Energy Industrial revenues of $128 million, up 3% year-over-year despite capacity constraints
• 1.96X 2021's revenues, effectively meeting a target set in early 2021 to double revenues by 2023

Current 2024 Baseline Revenue Outlook:

Initial Shipments from Supplemental Supply
In the fourth quarter of 2023, the company successfully delivered Energy Industrial products to customers through its supplemental supply.

"The successful launch of our supplemental supply provides critical capacity that we believe will enable our Energy Industrial business to live up to its full demand potential," commented Don Young, Aspen's President and CEO.

"We are proud of the results that the team delivered in 2023 by effectively doubling our revenues in two years, a goal that we've been striving for since early 2021," continued Mr. Young. "Our profitability profile is also vastly improved as we focus on driving to our gross margin and adjusted EBITDA margin targets of 35% and 25%, respectively."

Ricardo C. Rodriguez, Chief Financial Officer and Treasurer added, "There's potential for further growth beyond our current 2024 expectations. However, we remain cautious given the challenges that our customers face with launching and scaling new EV nameplates."

"We believe our best hedge to this uncertainty is continuing to optimize our cost structure, maximize the potential of our Energy Industrial business, broaden our EV customer base, right-time capital expenditures, and identify further operating efficiencies," continued Mr. Rodriguez. "We believe our December 2023 registered direct financing of $75 million positions us to capture additional demand upside and fully funds our near-term objectives as we turn EBITDA positive. It is also enabling potential long-term reductions in our cost of capital."

Aspen's preliminary 2023 results are based solely on information currently available to management and are unaudited. This financial information does not represent a comprehensive statement of Aspen's financial results for the fourth quarter or full year 2023 and remains subject to the completion of Aspen's financial closing procedures and internal reviews. As a result, Aspen's actual results for the fourth quarter and full year 2023 may vary materially from these preliminary estimates.

Aspen expects to release actual financial results for the fourth quarter on Monday, February 12, 2023, following the market close.

With respect to the 2024 baseline revenue outlook, Aspen may experience other events in 2024, including those related to the planned capacity expansion, supply chain disruptions or further cost inflation, that could cause actual results to vary materially from this baseline revenue outlook. See Special Note Regarding Forward-Looking and Cautionary Statements below.

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. 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.
