Steve Cotton, President and Chief Executive Officer, commented, “Aqua Metals continues to deliver on our stated objectives regarding the deployment of clean AquaRefining technology for recycling of lead-acid batteries. In addition, I am very excited about our advancements in applying AquaRefining technology to the recycling of lithium-ion batteries, which can significantly augment Aqua Metals capabilities and more than doubles our addressable market. During the third quarter, we finalized our first ever agreement to deploy AquaRefining technology at the facility of our new partner in Taiwan. Plans are currently being finalized for the shipping and installation of the phase 1 deployment package to the ACME Taiwan facility this quarter with plans for installation and initial operations during the first quarter of 2022. This operation will benefit from the enhancements recently made to our third generation Aqualyzer, that has achieved production over 300% of the original model. Also, during the third quarter, we established our new Innovation Center that is focused on developing the capability to utilize AquaRefining technology to recover metals from recycled lithium-ion batteries. Lab scale testing has already begun with promising results. In addition, we believe that our just announced collaboration agreement with LINICO will enable and evidence that our already proven technology can be applied to recycling lithium-ion batteries.”

Third Quarter 2021 Financial Results

During the third quarter of 2021, the Company achieved a historic milestone of finalizing its first agreement to deploy AquaRefining technology and equipment to a third-party facility, which was completed on July 28, 2021. As Aqua Metals concentrated its efforts on this agreement and further enhancing its product offerings for future partners, the Company did not generate revenue during the third quarter of 2021.

Cost of product sales increased slightly to $1.7 million compared to $1.6 million for the same period in 2020. The increase in cost of product sales was driven by accounting for legacy plant clean-up costs in preparation for the $14.25 million/$15.25 million lease-to-sale of the AquaRefinery in the Tahoe-Reno Industrial Center to our partner LINICO, which has been leasing the facility since April, 2021. General and administrative expenses for the third quarter of 2021 increased approximately 62% compared to the third quarter of 2020, driven primarily by non-cash costs. Increases in general and administrative expenses included changes in non-cash stock-based compensation as well as increased legal and insurance expenses.

Aqua Metals received an insurance payment of $5.25 million during the third quarter of 2021 related to the 2019 fire. This is the final insurance payment bringing the total collected to $30.25 million. As the amounts received have exceeded the original insurance receivable balance, that was limited by GAAP accounting standards, payments are reported as other income and are netted against related expenses.

During the third quarter of 2021, the Company reclassified certain assets with a net book value of $0.2 million to assets held for sale. Company management determined these are non-core assets and are no longer necessary for Aqua Metals future operating plans. In addition, in conjunction with the plant clean-up, the Company disposed of assets held for sale with a book value of approximately $1.4 million. These changes resulted in a non-cash loss on the disposal of fixed assets of $1.4 million for the quarter ended September 30, 2021, and total assets held for sale of $3.2 million as of September 30, 2021.

Interest expense decreased approximately 97% for the third quarter of 2021 compared to the same period in 2020. The decrease resulted from the retirement of the Veritex loan during the fourth quarter of 2020, leaving the Company debt free.

During the third quarter ended September 30, 2021, the Company recognized interest and other income of $0.3 million compared to $18,000 for the quarter ended September 30, 2020. The increase was primarily due to the payments received for scrap material salvaged during the plant clean-up process and a payment for electricity credits.  

For the third quarter of 2021, the Company had an operating loss of $4.6 million, compared to an operating loss of $3.4 million for the quarter ended September 30, 2020. The net loss for the third quarter was $1.4 million, or $0.02 per basic and diluted share, compared to a net loss of $1.8 million, or $0.03 per basic and diluted share, for the quarter ended September 30, 2020. The net loss reported for the third quarter of 2021 included the non-cash amount of $1.4 million recognized for the loss related to the disposal of property and equipment. 

As of September 30, 2021, the Company had $11.7 million in cash and cash equivalents. This balance does not reflect the $1.25 million deposit for the purchase of the McCarran Nevada facility, which was received subsequent to quarter end.

The previously announced lease-to-buy agreement related to the Company’s McCarran, Nevada plant commenced on April 1, 2021. The Company accounted for the lease-to-buy agreement as a sale-type lease. As a component of the accounting for this agreement, Aqua Metals recognized the estimated fair value of the land and plant of $17.0 million as a lease receivable. The Company applies the monthly lease payments received as a reduction to lease receivable and interest income. The lease receivable balance as of September 30, 2021, is reflected on the Company’s condensed consolidated balance sheets and allocated between a current and non-current portion.

Accrued expenses as of the quarter ended September 30, 2021, totaled $4.7 million, compared to $1.3 million for the quarter ended September 30, 2020. The most significant driver of the increase was $2.3 million for building repair costs that were accrued as part of the plant lease-to-buy agreement.
