&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Operating expenses of $17.6 million, an increase of 3.2%, as compared to Q1'2025, due primarily to impairment of goodwill and restructuring charges incurred as part of the wind down of the CO2 retail grocery business.

**Forward-Looking Statements**

Certain matters discussed in this press release and on the conference call are "forward-looking statements" within the meaning of Section 27A of the Securities Act of 1933, as amended, and Section 21E of the Securities Exchange Act of 1934, as amended. These forward-looking statements are based on information currently available to the Company and on management's beliefs, assumptions, estimates, or projections and are not guarantees of future events or results. Potential risks and uncertainties include risks relating to the future demand for the Company's products, risks relating to performance by our customers and third-party partners, risks relating to the timing of revenue, and any other factors that may have been discussed herein regarding the risks and uncertainties of the Company's business, and the risks discussed under "Risk Factors" in the Company's Form 10-K filed with the U.S. Securities and Exchange Commission ("SEC") for the year ended December 31, 2025, as well as other reports filed by the Company with the SEC from time to time.

------

**Use of Non-GAAP Financial Measures**

This press release includes certain non-GAAP financial measures, including adjusted operating margin, adjusted net loss, adjusted loss per share, adjusted EBITDA and free cash flow. Generally, a non-GAAP financial measure is a numerical measure of a company's performance, financial position, or cash flows that either exclude or include amounts that are not normally excluded or included in the most directly comparable measure calculated and presented in accordance with generally accepted accounting principles in the United States of America, or GAAP. These non-GAAP financial measures do not reflect a comprehensive system of accounting, differ from GAAP measures with the same captions, and may differ from non-GAAP financial measures with the same or similar captions that are used by other companies. As such, these non-GAAP measures should be considered as a supplement to, and not as a substitute for, or superior to, financial measures calculated in accordance with GAAP. The Company uses these non-GAAP financial measures to analyze its operating performance and future prospects, develop internal budgets and financial goals, and to facilitate period-to-period comparisons. The Company believes these non-GAAP financial measures reflect an additional way of viewing aspects of its operations that, when viewed with its GAAP results, provide a more complete understanding of factors and trends affecting its business.

**Notes to the Financial Results**

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;*• Adjusted operating margin* is a non-GAAP financial measure that the Company defines as loss from operations which excludes i) stock-based compensation; ii) restructuring charges, iii) restructuring - inventory reserve, iv) impairment of long-lived assets, and v) impairment of goodwill, divided by revenues.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;*• Adjusted loss per share* is a non-GAAP financial measure that the Company defines as net loss, which excludes i) stock-based compensation; ii) restructuring charges; iii) restructuring - inventory reserve, iv) impairment of long-lived assets; v) impairment of goodwill and vi) the applicable tax effect of the excluded items including the stock-based compensation discrete tax item, divided by basic shares outstanding.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;*• Adjusted EBITDA* is a non-GAAP financial measure that the Company defines as net loss which excludes i) depreciation and amortization; ii) stock-based compensation; iii) restructuring charges; iv) restructuring - inventory reserve, v) impairment of long-lived assets; vi) impairment of goodwill vii) other income, net, such as interest income and other non-operating income, net; and viii) benefit from income taxes.
