Aspen Aerogels, Inc. Reports Second Quarter 2020 Financial Results

and Recent Business Developments

NORTHBOROUGH, Mass., July 30, 2020 — Aspen Aerogels, Inc. (NYSE: ASPN) (“Aspen”) today announced financial results for the second quarter and first half of 2020, which ended June 30, 2020, and discussed recent business developments.

Total revenue for the second quarter was $24.6 million compared to $29.5 million in the second quarter last year. Second quarter net loss was $5.7 million compared to a net loss of $5.3 million in the second quarter of 2019. Net loss per share for the second quarter was $0.21 compared to a net loss per share of $0.22 in the second quarter last year.

Total revenue for the first half was $53.1 million compared to $57.4 million in the first half last year. First half net loss was $8.9 million compared to a net loss of $11.3 million in the first half of 2019. Net loss per share for the first half was $0.34 compared to a net loss per share of $0.47 in the first half last year.

Adjusted EBITDA for the second quarter was $(2.1) million compared to $(1.7) million in the second quarter of 2019. Adjusted EBITDA for the first half was $(1.6) million compared to $(4.2) million in the first half of 2019. A reconciliation of non-GAAP Adjusted EBITDA to net loss is provided in the financial schedules that are part of this press release. An explanation of this non-GAAP financial measure is also included below under the heading “Non-GAAP Financial Measures.”

Recent Business Developments

“As expected, our second quarter revenue declined 17% due to a decrease in subsea project work and the impact of COVID-19 on our maintenance related business, most notably in the U.S. petrochemical and refinery market. We did, however, experience year-over-year growth in on-shore project work globally, led by continued strong demand in the LNG market. In addition, our initiatives to reduce compensation, discretionary expenses and bill of material costs offset most of the impact of the decrease in revenue. As a result, we experienced a relatively modest decrease in gross profit and Adjusted EBITDA and increase in net loss versus the second quarter of 2019,” said Don Young, President and CEO of Aspen.

“Importantly, we continued to make solid progress on our strategy to leverage our aerogel technology platform within the electric vehicle market. During the quarter, we achieved a number of cost and performance milestones in our development effort with SKC Co., Ltd. to optimize our proprietary carbon aerogels to improve lithium-ion batteries for electric vehicles. In addition, our work with several automotive OEMs to explore the role our silica aerogel materials can play in impeding thermal runaway in lithium-ion batteries appears increasingly promising. We received an initial order for our silica aerogel blankets for one of Asia’s largest electric vehicle producers for use as a thermal runaway mitigation solution. We also are responding to a “request for quote” for our PyroThin^TM product for a leading North American electric vehicle manufacturer,” continued Mr. Young.

2020 Financial Outlook

Aspen issues a new 2020 full year outlook as follows:

Aspen’s new 2020 outlook assumes depreciation and amortization of $10.5 million, stock-based compensation expense of $4.0 million, interest and other expense of $0.2 million, and weighted average shares outstanding of 26.3 million for the full year.

“In April 2020, we withdrew our prior 2020 financial outlook due to the general uncertainty in the markets for our products resulting from the COVID-19 pandemic and the potential impact of significant volatility in the global oil markets. Looking forward to the second half of 2020, we anticipate that contractor access issues at energy facilities will continue to reduce demand for our products during the COVID-19 pandemic. While risks and uncertainties remain, we currently expect that our second half revenue will fall roughly in line with first half actuals with some potential for project-related upside. Accordingly, we expect to experience a year-over-year decrease in revenue, increase in net loss and a decrease in Adjusted EBITDA during the second half of the year,” stated Mr. Young.

“However, we are confident that Aspen’s underlying business fundamentals and operational effectiveness are strong. We also remain committed to fully implementing our strategy. We intend to complete our planned R&D investments, advance our electric vehicle

programs with the support of our partners, and implement our bill of material cost initiatives to continue to improve our profit potential,” said Mr. Young.

“We will also continue to monitor all aspects of our business to position Aspen Aerogels to successfully execute its strategy. We remain confident that the actions we’ve taken during 2020 both to reduce expenses and to bolster our financial resources will position us to navigate through the current challenging environment and to thrive when business conditions improve,” concluded Mr. Young.

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 measure included in this press release is Adjusted EBITDA. Management uses 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 they exclude 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 provide 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 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.
