Arq Inc. (ARQ) Q2 Revenue Beats Despite EPS Miss as EBITDA Growth Points to Operating Progress

The Quick Take

• Arq Inc. (ARQ) delivered Q2 2026 revenue that surpassed analyst expectations while EPS missed, reflecting ongoing investment in the company's activated carbon and power generation technology businesses.
• Strong adjusted EBITDA growth suggests operational improvements are translating to cash generation even as GAAP earnings remain pressured by depreciation and amortization charges.
• Arq's environmental technology position—supplying mercury and pollutant control solutions to coal-fired power plants—faces a structural demand question as the US power fleet transitions to natural gas and renewables.

Arq's Q2 result of a revenue beat paired with an EPS miss is a classic profile for a capital-intensive industrial company transitioning its business model. The company produces activated carbon products used for mercury control at power plants and is developing a granular activated carbon (GAC) line targeting water treatment markets. Revenue growth suggests commercial momentum in at least one of these segments, while the EPS miss may reflect higher depreciation from recent capital expenditure investments or non-cash amortization of intangible assets—both of which suppress GAAP earnings without representing cash outflows.

The strong adjusted EBITDA growth—highlighted as a key metric in the earnings commentary—is the most bullish signal in Arq's Q2 report. EBITDA growth in an asset-heavy industrial business indicates that gross margins and operational leverage are improving, even if accounting charges depress the bottom line. For investors focused on cash generation quality, the EBITDA trajectory is more informative than GAAP EPS for companies in heavy capital expenditure cycles.

The structural demand question for Arq's core activated carbon business is worth monitoring carefully. As coal-fired power plants retire across the US, the addressable market for mercury control solutions shrinks. Arq's diversification into water treatment GAC markets represents the strategic hedge against this secular decline. Progress in winning municipal water treatment contracts and securing EPA compliance-driven utility demand will be the key growth catalysts. The timing and pace of the coal retirement cycle will determine how much runway Arq has to complete its pivot.
