AI Brief

Q2 FY26 earnings call · Aug 11, 2026
Q2 FY26

TL;DR. Arq delivered Q2 2026 adjusted EBITDA of $5.8M (up 59% YoY) and gross margin of 38.5% (up 520 bps) on $29.9M in revenue, driven by its core PAC business, and reiterated full-year 2026 guidance of $120–125M revenue and $17–20M adjusted EBITDA. Management unveiled a new 'PAC for PFAS' product targeting water utilities near the 4 ppt threshold, while revealing the cost to complete its bituminous GAC plant could run $40–60M with no decision yet to invest.

Bullish
  • + Q2 adjusted EBITDA of ~$5.8M rose 59% YoY with gross margin up 520 bps to 38.5%, driven by core PAC business strength. new
  • + Q2 revenue grew ~5% YoY to $29.9M on improved pricing and volumes. new
  • + Management reaffirmed full-year 2026 guidance of $120–125M revenue and $17–20M adjusted EBITDA, signaling confidence in the seasonal ramp. new
  • + Net loss narrowed to $0.7M from $2.4M YoY and R&D spend fell 64% as prior-year GAC ramp costs did not repeat. new
  • + Corbin monetization optionality advanced, with positive NCAT asphalt trial results and ongoing third-party interest in sale or JV. new
Bearish
  • − GAC project completion cost estimate of $40–60M remains wide and unfinalized, and no investment decision has been made. new
  • − No bituminous GAC production or sales are expected in 2027, deferring the previously anticipated GAC revenue contribution. new
  • − Q2 SG&A rose ~$0.9M YoY to $6.8M driven by severance and recruiting costs tied to leadership transitions. new
  • − Unrestricted cash at quarter-end was only ~$0.9M, with total cash of $12.1M heavily restricted ($11.2M), and total debt rose to $30.7M from $28.5M at year-end. new
  • − PAC for PFAS is not expected to contribute materially to 2026 results, with only limited sales expected in the second half of 2026. new
