Aqua Metals, which is developing its AquaRefining clean recycling technology for lithium‑ion and lead‑acid batteries, reported a net loss of $4,480,000 for the three months and $8,434,000 for the six months ended June 30, 2026, with no commercial revenue. Total assets were $12,622,000 and stockholders’ equity $9,530,000 as of that date.
The company advanced its Project Headwaters ARC commercialization plans but recorded a $2,496,000 allowance for credit losses on its $4,160,000 Lion Energy participation interest after default and reduced information access. Cash and cash equivalents were $4,744,000, and operating cash outflow was $6,474,000 for the six months, leading management to conclude there is substantial doubt about continuing as a going concern despite raising $1,876,000 via its ATM program and $621,000 through its 2026 ESPP.
Aqua Metals, Inc. reported second quarter 2026 results and highlighted progress on its phased Headwaters ARC commercialization plan for LFP battery recycling. For the quarter ended June 30, 2026, the company recorded a net loss of $4,480 thousand, or $(1.31) per share, compared with a net loss of $6,770 thousand in the second quarter of 2025.
As of June 30, 2026, cash and cash equivalents were $4,744 thousand, with total assets of $12,622 thousand and stockholders’ equity of $9,530 thousand. The CEO noted that the company has entered the current commercialization phase debt-free and intends to align capital deployment with commercial milestones.
The Headwaters ARC plan is described as a staged model. Phase 1 focuses on mechanically processing LFP battery materials to produce copper and aluminum fines and high-specification black mass, building feedstock and offtake relationships. Phase 2 is expected to integrate AquaRefining™ to upcycle black mass into battery-grade lithium carbonate, iron phosphate and graphite. Aqua Metals is advancing diligence on a Midwest site of approximately 150,000 square feet on more than 50 acres, has logged over 5,000 operating hours at its demonstration plant, and was selected as an industrial partner on a DOE-funded program, while maintaining multiple commercial partnerships and memoranda of understanding.
Aqua Metals is asking stockholders to vote at its 2026 annual meeting on four key items. Stockholders will elect four directors, including CEO Stephen Cotton and three independent directors, and vote on an amendment to the 2019 Stock Incentive Plan.
The plan amendment would add 750,000 shares of common stock for equity awards, about 21% of the 3,543,793 shares outstanding as of June 30, 2026, to support long-term incentives for employees, executives, directors and advisors. Stockholders will also vote on ratifying Forvis Mazars, LLP as independent auditor for 2026 and cast an advisory “say‑on‑pay” vote on executive compensation.
The proxy details board independence, committee structures, a formal clawback policy tied to accounting restatements, insider trading and hedging restrictions, and change‑in‑control and severance protections for senior executives. It also discloses 2025 compensation, including total pay of $1,869,000 for the CEO.
Aqua Metals, Inc. reported a routine insider share withholding by Chief Eng and Opr Officer Benjamin S. Taecker. On July 1, 2026, 744 shares of common stock were withheld and returned to the company’s equity plan to cover tax obligations arising from the vesting of a previously reported restricted share grant. This was recorded as a tax-withholding disposition, not an open-market sale, at a price of $2.97 per share. After this transaction, Taecker directly held 57,321 common shares, including 24,727 shares underlying restricted stock units that are not yet vested and deliverable.
Aqua Metals, Inc. Chief Executive Officer Stephen Cotton reported a routine tax-related share disposition. On the vesting of a previously granted restricted share award on July 1, 2026, 2,402 shares of common stock were withheld and returned to the company plan to cover the related tax liability.
After this withholding, Cotton holds 217,271 shares of Aqua Metals common stock directly, which the disclosure states includes 81,522 shares underlying unvested restricted stock units that are not yet deliverable. The transaction did not involve an open-market purchase or sale of shares.
Aqua Metals, Inc. Chief Financial Officer Eric West reported a routine tax-withholding transaction related to a vesting of restricted stock. On the vesting date, 721 common shares were withheld and returned to the equity plan at a price of $3.91 per share to cover tax liabilities. Following this withholding, West directly holds 64,337 common shares, which includes 31,102 shares underlying restricted stock units that are not yet vested and deliverable.
Aqua Metals reported its first quarter 2026 results and strategic progress, highlighting narrower losses and continued commercialization efforts for its AquaRefining™ battery materials platform. The company is advancing toward its first commercial lithium battery recycling facility, working through U.S. site selection, detailed engineering, and partner engagement.
For the quarter ended March 31, 2026, Aqua Metals posted a net loss of $3.95 million, compared with a net loss of $8.32 million a year earlier, as total operating expense declined to $4.14 million from $8.68 million. Cash and cash equivalents were $6.82 million and total assets were $17.12 million as of March 31, 2026.
The company decided not to proceed with its previously outlined acquisition of Lion Energy under the February 11, 2026 non-binding term sheet, citing misalignment with its capital structure and shareholder value objectives. It continues to evaluate alternative, more capital-efficient ways to integrate selected energy storage assets while pursuing multiple commercial partnerships and technical validation at its Innovation Center.
Aqua Metals, Inc. reported a net loss of $3.95M for the quarter ended March 31, 2026, narrower than the $8.32M loss a year earlier, mainly because the prior period included a large non-cash impairment. The company still generated no revenue and used $3.84M of cash in operating activities.
Cash and cash equivalents were $6.82M with working capital of $7.48M, while management disclosed “substantial doubt” about the ability to continue as a going concern without new financing. Aqua Metals raised $1.30M via its at-the-market program and $0.62M through its employee stock purchase plan.
The company recorded a $437K allowance for credit losses on its $4.1M Lion Energy exposure, reflecting default under Lion’s senior facility and subordinated positioning. Development of its lithium-ion recycling technology and pilot operations continued, but commercialization and construction of a first commercial facility remain dependent on securing additional capital.
Aqua Metals, Inc. filed Amendment No. 1 to its 2025 annual report to add full Part III disclosures on directors, executive compensation, ownership, related-party transactions and auditor fees that were previously expected to come from a proxy statement. The company reports an aggregate market value of non-affiliate equity of $4,815,945 and 3,350,604 common shares outstanding as of March 24, 2026. The four-member Board includes three independent directors, separate chair and CEO roles, and active audit, compensation, and nominating/governance committees. The filing details substantial equity-based incentives and change-of-control severance for senior executives, a clawback policy for erroneously awarded incentive pay, stock ownership guidelines for directors, and related-party financings including a $3 million secured debt facility and a $1.5 million notes-and-warrants private placement involving insiders. Auditor Forvis Mazars, LLP billed $388,000 in 2025 audit fees.
