- What they said
- Management highlighted strong operational and financial performance in Q2 2026 following integration of HG Midstream assets. Gas gathered averaged over 4.1 Bcf/d (≈20% YoY increase). Adjusted EBITDA was a company record $289 million (2% YoY), capital invested was $47 million, and free cash flow after dividends was $80 million—marking the 12th consecutive quarter of free cash flow generation. Management received over $370 million from Veolia, reducing pro forma leverage to 2.8x and enabling calling the 2028 maturity; liquidity remains strong with undrawn credit capacity. Strategic initiatives include the East Side Express intrastate pipeline (1.5–2 Bcf/d capacity), expected to be underwritten by Antero Resources with estimated capex of $200–300 million over 2–3 years, and a broader pipeline/backlog of ~15 West Virginia projects. Management emphasized opportunities from accelerating gas-fired power generation, data center demand, and water reuse/closed-loop systems that should support higher returns and EBITDA growth into 2027. Management portrayed strong execution, financial flexibility, and a growth-oriented posture while noting limited downside from modest planned curtailments.
- Guidance
- Q3: high single-digit sequential EBITDA growth (driven by increased volumes), on track to achieve full-year EBITDA guidance. East Side Express capex expected $200–300 million over the next 2–3 years (roughly ~$100 million/year). Management also referenced high single-digit EBITDA growth for 2027 tied to water system connections and expanded operations.
- Risks flagged
- Concentration risk from reliance on Antero Resources (AR) to underwrite projects and supply a substantial portion of volumes; project execution and timing risk for East Side Express and other regional pipeline projects (dependence on FIDs from power/data projects); potential for increased seasonality due to curtailments (though management quantified this as modest); dependence on regional demand growth (power plants, data centers) which requires successful FIDs and construction.
