Ricardo C. Rodriguez, Chief Financial Officer and Treasurer noted, "We added $10 million of revenue quarter over quarter, a 12% increase. More importantly, we increased Adjusted EBITDA by 42% quarter over quarter, to $12.9 million, and operating income increased by 76%, further validating the scalability of our operations. We are increasingly optimistic about our outlook for the year as our main automotive OEM customers capture their fair share of the EV market, and our Energy Industrial customers benefit from incremental supply through our external manufacturing facility." Mr. Rodriguez added, "These elements, combined with our team's continued execution, enable us to raise our 2024 baseline Adjusted EBITDA outlook by 83%, to $55 million on $380 million of revenue, and to anticipate positive net income for the year."

Aspen may incur, among other items, additional charges, realize gains or losses, incur financing costs or interest expense, or 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 outlook.

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 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.
