Ricardo C. Rodriguez, Chief Financial Officer and Treasurer noted, "We're increasingly optimistic about our EV customers' ability to ramp up production in 2024 and see meaningful upside potential to our outlook. In the meantime, we remain focused on gearing the business for sustained profitability that isn't dependent on outsized revenue growth. We will continue managing our fixed cost base within clear targets, right-timing capital investments, and increasing our focus on cash conversion. The last quarter of 2023 gave us a glimpse of what our asset base can deliver, and our team is energized to drive additional scale in 2024."

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.
