Q1 2022 Highlights and Recent Business Developments

• Total first quarter 2022 revenue of $38.4 million grew 37% year-over-year.
• First quarter PyroThin^® thermal barrier record revenue of $7.6 million increased 41% compared to the fourth quarter 2021.
• Strengthened balance sheet with financing from Koch Strategic Platforms ("KSP") comprised of $100.0 million convertible notes and $50.0 million common stock equity.
• Raised $23.6 million through the At-the-Market ("ATM") equity offering, which went into effect March 16, 2022.
• Broke ground at the Company's second aerogel manufacturing plant ("Plant II"). The Statesboro, Georgia advanced aerogel manufacturing facility supports Aspen's thermal barrier expansion plan in the fast-growing electric vehicle ("EV") market.
• Received Overdrive Award as part of GM's 30th Annual Supplier of the Year awards (for Launch Excellence recognizing Aspen's key role in GM's Ultium battery platform thermal propagation strategy).

"Aspen is off to a strong start for the year," commented Don Young, Aspen's President and CEO. "Total first quarter revenue grew 37% year-over-year and 22% sequentially, reflecting continued penetration in the EV market and healthy energy industrial growth." Mr. Young added, "We significantly strengthened Aspen's balance sheet during the quarter, with financings comprised of a $150.0 million follow-on investment from KSP and $23.6 million raised through our ATM equity offering. These investments increase the financial resources we have available to capitalize on significant opportunities in our commercial markets and give us improved flexibility with regard to the timing of future capital raises to support our planned growth. We will maintain a multi-faceted efficient approach to raising capital, including the potential utilization of public offerings, strategic financings, government supported financing vehicles, and debt, where appropriate."

2022 Financial Outlook

Aspen's 2022 full year outlook remains unchanged.

• Total revenue is expected to range between $145.0 million and $155.0 million
• Net loss is expected to range between $66.7 million and $70.7 million
• Adjusted EBITDA is expected to range between $(42.0) million and $(46.0) million
• Net loss per share is expected to range between $1.88 and $1.99

The Company's 2022 outlook assumes depreciation and amortization of $9.7 million, stock-based compensation expense of $8.2 million, interest expense of $6.8 million and weighted average shares outstanding of 34.2 million for the full year.

Mr. Young noted, "Our growth targets remain unchanged for a doubling of revenue from 2021 to 2023 and tripling revenue from 2023 to 2025 to approximately $720 million. We are increasing our investment levels throughout the year to keep pace with the size and intensity of growth within our PyroThin thermal barrier business. These investments are focusing on Plant II; a high-volume fabrication operation in Mexico; and enhancing the technical, commercial and operational teams that support our thermal barrier business. Leveraging higher volumes, coupled with the impact of these investments, advances our path to profitability and sets the stage for strong revenue and profit growth through the decade."

A reconciliation of non-GAAP Adjusted EBITDA to net loss for the 2022 financial outlook 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."

Aspen Aerogels may incur charges, realize gains or losses, incur financing costs or interest expense, or experience other events in 2022, including those related to the planned capacity expansion, that could cause actual results to vary materially from this outlook.

Conference Call Notification
A conference call with Aspen management to discuss first quarter 2022 results and recent business developments will be held at 8:30 am ET on April 28, 2022. During the call, management will respond to questions concerning, but not limited to, Aspen's financial performance, business conditions, and financial outlook. Management's discussion and responses could contain information that has not been previously disclosed. Shareholders and other interested parties may call (844) 200-6205 (domestic) or (929) 526-1599 (international) and reference conference ID "313156" to participate in the conference call.

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.
