Industry Context

These transactions position Antero Midstream as a more focused and scaled pure-play midstream operator in the Appalachian Basin, specifically strengthening its presence in the Marcellus Shale, a low-cost basin. The divestiture of Utica Shale assets, which had limited future development, allows the company to reallocate capital to its core, higher-growth Marcellus operations. The simultaneous upstream acquisition by Antero Resources from the same seller (HG Energy) indicates a coordinated strategy between the related entities to consolidate and optimize their respective asset bases in key regions.

Comparison to Industry Standards

• The HG Midstream acquisition multiple of 7.0x (adjusted for synergies) is generally considered attractive for midstream assets, especially for a strategic bolt-on in a core basin with an investment-grade customer like Antero Resources. This multiple suggests a favorable valuation compared to some broader industry averages for midstream infrastructure.
• The Utica Shale divestiture multiple of over 11x next three years average annual EBITDA is a strong valuation for non-core assets with limited future development, indicating a successful monetization of less strategic infrastructure at a premium.
• The expected immediate accretion of over 15% to Free Cash Flow after dividends from the acquisition demonstrates strong financial discipline and value creation, which is a key metric for midstream companies and often exceeds typical accretion targets for similar transactions in the sector.
