Aqua Metals, Inc.

Part I, Item 1A of our Annual Report on Form 10-K for the year ended December 31, 2024 includes certain risk factors that could materially affect our business, financial condition or future results. There have been no material changes to those risk factors, except as described below:

We will need additional financing to execute our business plan and fund operations, which additional financing may not be available on reasonable terms or at all*.* As of March 31, 2025, we had cash and cash equivalents of approximately $1,589,000, current liabilities of $7,164,000 and a working capital deficit of $4,945,000. As of the date of this report, we believe that we will require additional capital in order to fund our current level of ongoing costs and our proposed business plan over the next 12 months as we move forward with our business strategy. We intend to acquire the necessary capital though debt financing, sale of assets or through the sale of equity. Funding that includes the sale of our equity may be dilutive. If such funding is not available on satisfactory terms, we may be unable to further pursue our business plan and we may be unable to continue operations, in which case you may lose your entire investment.

The report of our independent registered public accounting firm for the year ended December 31, 2024 states that there is substantial doubt about our ability to continue as a going concern within one year after the date that the financial statements are issued.
