1. Organization

Aqua Metals (NASDAQ: AQMS) is engaged in the business of applying its commercialized clean, water-based recycling technology principles to develop the clean and cost-efficient recycling solutions for both lead and lithium-ion batteries, or "Li". We offer technology licensing and related services to recyclers across the globe for lead recycling and expect to provide recycling services for Li batteries. Our recycling process is a patented hydrometallurgical technology that is a novel, proprietary and patented process we developed and named "AquaRefining". AquaRefining is a room temperature, water and organic acid-based process that greatly reduces environmental emissions. The modular Aqualyzers cleanly generate ultra-pure metal one atom at a time, closing the sustainability loop for the rapidly growing energy storage economy. Our process was originally designed for lead recycling. Lead is a globally traded commodity with a worldwide market value in excess of $20 billion. We believe our suite of patented and patent pending AquaRefining technologies will allow the lead-acid battery industry to simultaneously improve the environmental impact of lead recycling and scale recycling production to meet demand. Furthermore, our AquaRefining technologies result in high purity lead. We are also applying our commercialized clean, water-based recycling technology principles with the goal of developing the cleanest and most cost-efficient recycling solution for lithium-ion batteries. We believe our process has the potential to produce higher quality products at a lower operating cost without the damaging effects of furnaces and greenhouse emissions. Aqua Metals estimates its total addressable market for lithium-ion battery recycling will be approximately $9 billion by 2025 and grow to exceed lead battery recycling by the end of the decade. Unlike the mature lead recycling market, the deployed lithium-ion battery recycling infrastructure to serve market growth does not exist today.

We were formed as a Delaware corporation on June 20, 2014 for the purpose of engaging in the business of recycling metals through our patent-pending process that we developed and named “AquaRefining”. Since 2015, Aqua Metals has developed breakthrough metal recycling technologies that utilize a clean, closed-loop process that can produce ultra-high purity metal. Our innovative approach, AquaRefining, delivers raw materials back into the manufacturing supply chain while reducing emissions and toxic byproducts and creating a safer work environment. The patented AquaRefining modular systems have already demonstrated how they can reduce environmental impact and scale lead-acid battery recycling capacity.

We completed the development of our first LAB recycling facility at the Tahoe Reno Industrial Center in McCarran, Nevada (“TRIC”) and commenced production of battery breaking. During 2020 and 2021, we successfully iterated our lead AquaRefining Aqualyzer through a 1.25 and a 1.5 version which now has triple the throughput of the 2019 iteration that produced over 35,000 industry standard ingots in commercial production. During the second half of 2022, we are deploying and operating a Phase 1 deployment of lead AquaRefining with our partner ACME Metal in Taiwan. This showcase installation will inform management of the interest in ACME to move forward with larger deployments by the first quarter of 2023 as well as other potential licensees and partners in the same timeframe.

In February 2021, we announced a strategic investment in LINICO Corporation of up to $2 million to be paid in Aqua Metals shares and cash for an approximate 12% ownership in LINICO as part of our strategy to strengthen growth by potentially applying AquaRefining intellectual property to lithium-ion battery recycling while meeting our lead recycling commercial guidance. In November 2021, Aqua Metals and LINICO signed a collaboration agreement which sets the parameters for future research and development cooperation, as both companies expand into lithium-ion battery recycling and advance our technologies designed to recycle lithium-ion batteries cost-effectively and sustainably. Aqua Metals and LINICO plan to source the necessary lithium-ion feedstock from battery manufacturing scrap and end-of-life cells from various sources, including electric vehicle battery suppliers interested in participating in the eco-network the two companies announced in 2021. LINICO intends to process the feedstock into high-quality black mass utilizing its proprietary process. The resulting black mass will be used as input feedstock for Aqua Metals’ AquaRefining pilot cells intended to create high purity metals such as nickel, cobalt, and copper as well as other compounds.

In August 2021, we announced that we had established an Innovation Center focused on applying our proven technology to lithium-ion battery recycling research and development and prototype system activities. During the first half of 2022, we announced our ability to recover copper, lithium hydroxide, nickel, and cobalt from lithium-ion battery black mass at the Company's Innovation Center. Our strategic decision to apply our proven clean, closed-loop hydrometallurgical and electro-chemical recycling experience to lithium-ion battery recycling is designed to meet the growing demand for critical metals driven by the global transition to electric vehicles, growth in Internet data centers, and alternative energy applications including solar, wind, and grid-scale storage. In July 2022, we signed a letter of intent with Dragonfly Energy Corporation, a leader in lithium-ion deep cycle batteries, pursuant to which Dragonfly would purchase commercial quantities of lithium hydroxide for ongoing development of solid-state lithium-ion battery technologies and future manufacturing activities. The Company is on schedule to have the Innovation Center’s lithium-ion recycling pilot plant to be fully operational in the fourth quarter of 2022.

2. Summary of Significant Accounting Policies

The significant accounting policies and estimates used in preparation of the condensed consolidated financial statements are described in the Company’s audited consolidated financial statements as of and for the year ended December 31, 2021, and the notes thereto, which are included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2021, as filed with the Securities and Exchange Commission, or the SEC, on February 24, 2022. There have been no material changes in the Company’s significant accounting policies during the three and nine months ended September 30, 2022.

Basis of presentation

The accompanying unaudited condensed consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America (“U.S. GAAP”) as found in the Accounting Standards Codification (“ASC”) and Accounting Standards Updates ("ASU") of the Financial Accounting Standards Board (“FASB”) and pursuant to the rules and regulations of the SEC. Accordingly, they do not include all the information and footnotes required by such accounting principles for complete financial statements. In the opinion of management, all adjustments (which include normal recurring adjustments) considered necessary to present fairly each of the condensed consolidated balance sheet as of September 30, 2022, the condensed consolidated statements of operations for the three and nine months ended September 30, 2022 and September 30, 2021, the condensed consolidated statements of stockholders' equity for the three and nine months ended September 30, 2022 and September 30, 2021 and the condensed consolidated statements of cash flows for the nine months ended September 30, 2022 and September 30, 2021, as applicable, have been made. The condensed consolidated balance sheet as of December 31, 2021 has been derived from the Company’s audited financial statements as of such date, but it does not include all disclosures required by U.S. GAAP. The accompanying unaudited condensed consolidated financial statements should be read in conjunction with the Company's audited consolidated financial statements for the period ended December 31, 2021, which are included on Form 10-K filed with the Securities and Exchange Commission on February 24, 2022.

The results of operations for the three and nine months ended September 30, 2022 are not necessarily indicative of results that may be expected for the year ending December 31, 2022.

Principles of consolidation

The accompanying unaudited condensed consolidated financial statements include the accounts of the Company and its Subsidiaries, both of which are wholly-owned subsidiaries. Significant inter-company accounts and transactions have been eliminated in consolidation.

Use of estimates

The preparation of the condensed consolidated financial statements requires management of the Company to make a number of estimates and assumptions relating to the reported amount of assets and liabilities and the disclosure of contingent assets and liabilities at the date of the condensed consolidated financial statements, and the reported amounts of expenses during the period. Significant items subject to such estimates and assumptions include the carrying amount and valuation of long-lived assets, valuation allowances for deferred tax assets, the determination of stock option expense and the determination of the fair value of stock warrants issued. Actual results could differ from those estimates.

Net loss per share

Basic net loss per share is computed by dividing net loss by the weighted average number of common shares outstanding during the period. Diluted net loss per share is computed by dividing the net loss by the weighted average number of common share equivalents outstanding for the period determined using the treasury-stock method or the if-converted method, as applicable. For purposes of this calculation, stock options, restricted stock units (RSUs) and warrants to purchase common stock are considered to be common stock equivalents and are only included in the calculation of diluted net loss per share when their effect is dilutive. The following shares underlying outstanding convertible notes, stock options, RSUs and warrants to purchase common stock were anti-dilutive due to a net loss in the periods presented and, therefore, were excluded from the dilutive weighted average securities computation for the three and nine months ended September 30, as indicated below:

	Three Months Ended September 30,				Nine Months Ended September 30,
Excluded potentially dilutive weighted average securities (1):	2022		2021		2022		2021

Options to purchase common stock		1,009,230		1,038,439		1,018,900		1,115,380
Unvested restricted stock units		3,221,803		3,772,069		3,921,702		4,543,145
Financing warrants to purchase common stock		6,372		6,372		6,372		6,372
Total potential dilutive weighted average securities		4,237,405		4,816,880		4,946,974		5,664,897

(1)	Securities are presented on a weighted average outstanding calculation as required if the securities were dilutive

Concentration of credit risk

The Company did not generate revenue other than nominal revenue from the sale of inventory during the three and nine months ended September 30, 2022 or the three and nine months ended September 30, 2021. The accounts receivable balance on the Company's condensed consolidated balance sheets as of September 30, 2022 and December 31, 2021 consisted of amounts due from the return or sale of inventory and proceeds from assets held for sale.

Recent accounting pronouncements

There were no recent accounting pronouncements or changes in accounting pronouncements during the nine months ended September 30, 2022 that are of significance or potential significance to the Company.

Insurance Proceeds

On November 29, 2019, there was a fire in the AquaRefining area of the TRIC facility. As of December 31, 2021, the Company had received a total of $30.25 million in insurance payments as a result of the fire damage. The Company does not expect any additional insurance payments related to this matter.

3. Revenue Recognition

The Company has historically generated revenues by recycling lead acid batteries (“LABs”) and selling the recovered lead to its customers. Primary components of the recycling process include sales of recycled lead consisting of lead compounds, ingoted hard lead and ingoted AquaRefined lead as well as plastics. The Company commenced the shipment of products for sale, consisting of lead compounds and plastics, in April 2017, and through March 31, 2018, all revenue was derived from the sale of lead compounds and plastics. In April 2018, the Company began shipping lead bullion in addition to lead compounds and plastics. In June 2018, the Company began shipping high purity lead from its AquaRefining process.

The Company was not in commercial production during the three and nine months ended September 30, 2022 or during the three and nine months ended September 30, 2021. Historically, Company products transferred to customers at a single point in time accounted for 100% of its revenue.

4. Lease Receivable

The Company has entered into an Industrial Lease Agreement with LINICO Corporation, a Nevada corporation, or ("LINICO"), dated February 15, 2021 pursuant to which the Company has leased to LINICO its 136,750 square foot recycling facility at TRIC. The lease commenced April 1, 2021 and expires on March 31, 2023. During the lease term, LINICO has the option to purchase the land and facilities at a purchase price of $14.25 million if the option is exercised and the sale is completed by October 1, 2022 and $15.25 million if the option is exercised and the sale is completed after October 1, 2022 and prior to March 31, 2023. The purchase option is subject to LINICO’s payment of a nonrefundable deposit of $1.25 million, which was paid on October 15, 2021, and a second nonrefundable deposit of $2.0 million by November 1, 2022, both of which will be applied towards the purchase price. LINICO did not exercise the option to purchase the land and facilities at a purchase price of $14.25 million on October 1, 2022. The lease agreement is a triple-net lease pursuant to which LINICO is responsible for all fixed costs, including maintenance, utilities, insurance, and property taxes. The lease agreement provides for LINICO’s monthly lease payments starting at $68,000 per month and increasing to $100,640 in the last six months of the lease.

With respect to the portion of the facility that was damaged in the November 2019 fire, consisting of approximately 30,000 square feet, the Company was obligated to complete the clean-up of the damaged area, at the Company's expense and repair all damage to the damaged area, at the Company's expense. Both the clean-up and the repair of the building has been completed. With regard to the equipment on-site at TRIC, the Company has granted LINICO the right of first offer to purchase any equipment the Company offers for sale. The lease agreement contains customary representations, warranties and indemnities on the part of both parties.

The Company accounted for the Industrial Lease and Option to Purchase Agreement as a sales-type lease. As a component of the accounting for the agreement, the Company recognized the estimated fair market value of the land and plant of $17.0 million as a lease receivable, which is reflected on the Company's condensed consolidated balance sheets. The implied interest rate of 0.5% was utilized for the amortization of the scheduled building lease/purchase payments outlined in the agreement. The Company applies the monthly payments received as a reduction to lease receivable and interest income. The interest income recognized from the agreement is included in "Interest and other income" on the Company's condensed consolidated statements of operations. For the nine months ended September 30, 2022, the Company recognized a reduction in the lease receivable balance of approximately $636,000 and recorded $57,000 of interest income related to this agreement.

8. Investments

On February 15, 2021, the Company entered into a Series A Preferred Stock Purchase Agreement with LINICO Corporation, a Nevada Corporation, or ("LINICO"), that provided for the Company's issuance of 375,000 shares (“Aqua Shares”) of the Company's common stock in consideration of LINICO’s issuance of 1,500 shares of its Series A Preferred Stock, at a stated aggregate value of $1.5 million, along with a three-year warrant (“Series A Warrant”) to purchase an additional 500 shares of LINICO Series A Preferred Stock at an exercise price of $1,000 per share. During the three months ended March 31, 2022, the Company exercised the warrant for all 500 LINICO Series A Preferred shares. Following the exercise, the Company held a total of 2,000 shares of the Series A Preferred Stock representing approximately 12% of LINICO common stock on a fully diluted basis.

The Company accounted for the LINICO investment under ASC 321, Investments-Equity Securities, using the measurement alternative of recording at cost as the investment in LINICO doesn’t have a readily determinable fair value.

The LINICO Series A Preferred Stock is senior to all other capital stock of LINICO with regard to dividends and distributions upon liquidation, dissolution and sale of the company. Each share of LINICO Series A Preferred Stock is entitled to one vote per share and votes with the common stock on all matters, subject to certain protective provisions that require the approval of the holders of the Series A Preferred Stock voting as a class. The Series A Preferred Stock accrues a cumulative dividend of 8% per annum on the original stated value of $1,000 per share, and all accrued and unpaid dividends on the Series A Preferred Stock must be paid in full prior to the payment of any dividends on any other shares of LINICO capital stock. In the event of any liquidation or dissolution of LINICO, which would include a sale of LINICO, the holders of the Series A Preferred Stock shall receive the return of their stated value of $1,000 per share plus all accrued and unpaid dividends prior to any distribution to the holders of any other capital stock of LINICO, following which the holders of the Series A Preferred Stock shall participate in the distribution of any remaining assets with the holders of the junior stock on an as-converted basis. The Series A Preferred Stock is convertible into shares of LINICO common stock at the Company's option and is automatically converted into LINICO common stock upon the election of the holders of a majority of the LINICO Series A Preferred Stock or upon a qualifying IPO of LINICO common stock. The Series A Preferred Stockholders are also provided with preemptive rights allowing them the right to purchase their proportional share of certain future LINICO equity issuances.

The Series A Preferred Stock Purchase Agreement includes customary representations, warranties, and covenants by LINICO and the Company.

As LINICO’s sale of the 375,000 of Aqua Shares resulted in net proceeds to LINICO that were less than $1,500,000, the Company was required to pay LINICO the difference of $232,000 in cash.

In connection with the investment transactions, the Company also entered into an Investors Rights Agreement and a Voting Agreement, each dated February 15, 2021, pursuant to which LINICO granted the Company customary demand and piggyback registration rights, information rights and the right to nominate one person to the LINICO board of directors as long as the Company is the owner of at least 10% of the LINICO common stock on a fully-diluted basis.

Comstock Inc., a Nevada corporation (NYSE-MKT: LODE), is the beneficial owner of approximately 88% of the common shares of LINICO. The Company's Chief Financial Officer, Judd Merrill, is a member of the board of directors of Comstock Inc.
