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 additional financial metrics that are not prepared in accordance with GAAP ("non-GAAP"). The non-GAAP financial measures included in this press release are Adjusted EBITDA, adjusted net loss and adjusted net loss per share. Management uses these non-GAAP financial measures, in addition to GAAP financial measures, as a measure of operating performance because the non-GAAP financial measures do 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 these non-GAAP financial measures reflect 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 these 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. These non-GAAP measures may not be comparable to similarly titled measures presented by other companies.

The non-GAAP financial measures do 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), adjusted net loss to net loss and adjusted net loss per share to net loss per share, in each case 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. About Aspen Aerogels, Inc.
