Business context and reporting period
Arq, Inc. (formerly Advanced Emissions Solutions) filed this Form 10-K for the fiscal year ended December 31, 2023; it reports full-year results, not standalone fourth-quarter results. Arq sells activated carbon and other contaminant-treatment products, with existing exposure to coal-fired power generation and expansion plans in water, industrial and remediation markets. The February 2023 acquisition of Legacy Arq added a Kentucky coal-waste processing facility and technology intended to supply feedstock for granular activated carbon (GAC). The company adopted the Arq name and ARQ ticker in February 2024.
Financial performance and position
| Metric | 2023 | 2022 |
|---|---|---|
| Revenue | $99.2 million | $103.0 million |
| Operating loss | $13.3 million | $12.1 million |
| Net loss | $12.2 million | $8.9 million |
| Adjusted EBITDA (non-GAAP) | $(2.6) million | $1.3 million |
| Cash used in operating activities | $16.7 million | $6.1 million |
| Cash used in investing activities | $28.5 million | $4.6 million |
Revenue was entirely from consumables. Cost of revenue, excluding depreciation and amortization, was $67.3 million; on that basis, gross profit was approximately $31.9 million, or 32.1% of revenue, versus $22.5 million, or 21.9%, in 2022. The filing attributes the improvement mainly to better pricing, lower feedstock and additive costs, product mix, and $4.7 million of revenue from minimum-quantity contract settlements; lower sales volumes weighed on margins.
At year-end, cash was $45.4 million and restricted cash was $8.8 million. Current assets were $86.5 million against current liabilities of $23.0 million. Total debt carrying value was $20.9 million, including the $10.0 million CFG loan and the assumed CTB loan; the debt table reports $23.0 million before unamortized discounts and issuance costs. Total liabilities were $57.1 million and stockholders’ equity was $178.4 million.
Cash and restricted cash declined $22.3 million to $54.2 million. Financing provided $22.9 million, principally from stock issuance and the CFG loan, partially funding operating and investment outflows. The company reported a $2.7 million gain on the sale of Marshall Mine and $1.6 million of equity-method earnings, down from $3.5 million in 2022. Its $86.1 million of tax-credit carryforwards and other deferred tax assets were fully offset by a valuation allowance; management concluded realization was not more likely than not.
Material changes versus 2022
- Revenue declined 4%, primarily because lower natural-gas prices reduced coal-fired generation and product volumes; improved pricing added approximately $10.6 million.
- Net loss increased by $3.3 million, while Adjusted EBITDA moved from positive $1.3 million to negative $2.6 million. Higher payroll, general and administrative costs, depreciation and interest contributed; the 2023 results also included acquisition and integration costs.
- Operating cash use increased by $10.6 million, including significant payments on acquired payables and accrued expenses. Investing cash use rose with acquisition-related and expansion spending.
- The acquisition expanded assets and operations but also added debt, employees and operating costs. Legacy Arq generated no revenue after acquisition in 2023 and contributed $11.7 million of net loss, according to the filing.
Outlook, risks and unusual items
Management expects year-end 2023 cash to fund operations for the next 12 months at current operating levels, but says additional financing is needed to meet its construction and production targets. Arq targets commercial Arq Powder and GAC production by the end of 2024. It estimates Red River GAC construction costs of $62–$67 million and Corbin construction and commissioning costs of $10–$15 million. It expects to spend $45–$50 million on the Red River expansion and $5–$10 million on Corbin in 2024. Potential funding sources include cash, operating cash generation, cost reductions, customer prepayments, and refinancing or expanding the term loan; failure to secure financing could delay the projects.
The CFG loan bears cash interest at a floating benchmark plus a 9% margin (or base rate plus 8%) and an additional 5% paid in kind. It includes a $5 million minimum unrestricted-cash covenant, minimum revenue requirements of $85 million for 2024 and $100 million thereafter, and minimum Consolidated EBITDA of $3 million for 2024 and $16 million thereafter. The filing does not clearly state whether the company has arranged the expected refinancing or how it will fund all planned spending.
Key risks include construction delays or cost overruns, difficulty scaling and selling products not yet commercially established, customer concentration (top three customers were 37% of consumables revenue), dependence on coal generation and environmental rules, supply and transportation constraints, and competition. Surety bonds totaled $11.2 million, supported in part by restricted cash; reclamation obligations were $6.2 million. The company disclosed limited contingent guarantees related to Tinuum Group and no significant legal proceedings at year-end. The audited financial statements received an unqualified opinion; management reported effective disclosure controls and internal controls, but excluded Legacy Arq from the internal-control assessment while integration work continues. No cybersecurity incident had materially affected operations.
Important facts for investors to verify
- Funding availability, loan refinancing terms and covenant compliance for the 2024 buildout, including the timing and total cost of both facilities.
- Actual commissioning, production ramp, product quality, customer acceptance and contracted demand for Arq Powder and GAC.
- Whether operating cash use moderates and whether the reported 12-month liquidity outlook remains valid after planned capital spending; distinguish unrestricted cash from restricted cash.
- Customer concentration, coal-generation trends, regulatory developments affecting mercury and PFAS treatment, and the effect of input and transport costs on margins.
- Potential dilution from future financing and the usability of tax-credit carryforwards, including possible ownership-change limits.
