The Company’s ability to meet its liquidity needs will largely depend on its ability to generate cash in the future. During the three months ended March 31, 2023, the Company used $<span id="xdx_909_eus-gaap--CashAndCashEquivalentsAtCarryingValue_iI_pn3n3_dm_c20230331__us-gaap--CashAndCashEquivalentsAxis__us-gaap--CashEquivalentsMember_z5H8AdikCvy4" title="Cash">11.4</span> million of cash in operating activities, and the Company’s ability to generate cash in the future is subject to general economic, financial, competitive, legislative, regulatory, and other factors that are beyond the Company’s control. The transition to profitability is dependent upon the successful development, approval, and commercialization of its products and the achievement of a revenue level adequate to support its cost structure. Based on the Company’s current operating plan, the Company believes that its cash and cash equivalents as of March 31, 2023 of $<span id="xdx_900_eus-gaap--CashEquivalentsAtCarryingValue_iI_pn3n3_dm_c20230331_zd7CRfRkFnqf" title="Cash">19.5</span> million will not be sufficient to fund operations and capital expenditures for the twelve months following the filing of this Quarterly Report on Form 10-Q, and the Company will need to obtain additional funding. In July 2022, the Company received official ratification from the European Commission of the European Union for one of the Important Projects of Common European Interest (“IPCEI”), Green HiPo. This project provides for the availability of funding of €782.1 million over the next six years. As of the issuance date of the unaudited condensed consolidated financial statements, the Company has not received an agreement which provides the terms of the funding. In addition, on April 10, 2023, the Company entered into a purchase agreement (the “Purchase Agreement”) with Lincoln Park Capital Fund, LLC (“Lincoln Park”), which provides that the Company has the right, but not the obligation, to sell to Lincoln Park up to $50 million worth of shares of the Company’s common stock, par value $<span id="xdx_902_eus-gaap--CommonStockParOrStatedValuePerShare_c20230331_pdd" title="Common stock, par value (in dollars per share)">0.0001</span> (the “Common Stock”), from time to time over the 36 month term of the Purchase Agreement. Concurrently with entering into the Purchase Agreement, the Company also entered into a registration rights agreement with Lincoln Park, pursuant to which the Company agreed to register the resale of the shares of the Company’s Common Stock that have been and may be issued to Lincoln Park under the Purchase Agreement pursuant to a registration statement (the “Registration Statement”). The Registration Statement was filed on April 21, 2023 and declared effective on May 2, 2023. Per the terms of the Purchase Agreement, the Company will be unable to sell shares of the Company’s Common Stock to Lincoln Park if the sale price falls below $0.50 per share. Therefore, there is no assurance that the Company will have full access to the facility over the next twelve months. If the Company is unable to obtain sufficient funding, it could be required to delay its development efforts, limit activities and reduce research and development costs, which could adversely affect its business prospects. Because of the uncertainty in securing additional funding and the insufficient amount of cash and cash equivalents as of the financial statement filing date, management has concluded that substantial doubt exists with respect to the Company’s ability to continue as a going concern for one year from the date the unaudited condensed consolidated financial statements are issued.</span></p>

Management bases its estimates and judgments on historical experience and on various other factors that are believed to be reasonable under the circumstances, the results of which form the basis for making judgments about the carrying values of assets and liabilities that are not readily apparent from other sources.
