Antero Resources (NYSE: AR) said it will acquire the upstream assets of HG Energy II, LLC for $2.8 billion in cash, plus the assumption of HG’s commodity hedge book, subject to customary closing adjustments. The deal is expected to close in 2Q 2026 with an effective date of January 1, 2026. In parallel, Antero agreed to sell its Ohio Utica Shale upstream assets for $800 million in cash, expected to close in 1Q 2026 with an effective date of July 1, 2025.

Why this matters: Marcellus scale + inventory life, funded by a Utica exit

The HG acquisition is a strategic “add-on” in West Virginia’s core Marcellus, directly expanding Antero’s operated footprint and sharpening its position as a liquids-weighted Marcellus developer. Antero says the HG package adds:

• ~850 MMcfe/d of expected 2026 production

• 385,000 net acres that offset Antero’s existing ~475,000 net core position

• 400+ remaining gross locations with high NRIs and 20,300-foot average laterals

• an estimated ~5-year inventory life extension at maintenance capital levels

Antero also laid out a sizable synergy case: ~$950 million of synergies over 10 years on a PV-10 basis, including ~$550 million tied to development planning optimization and D&C savings, and ~$400 million tied to net marketing, water handling optimization, and tax benefits.

Who is HG Energy, and why PE is selling now?

HG Energy is a long-standing Appalachian operator that has been private equity-backed, including sponsorship by Quantum Capital Group, one of the largest and most active energy-focused PE firms. HG has built a reputation as a scale consolidator—assembling and developing positions across the region over multiple cycles, often using infrastructure/operating discipline as a differentiator.

This transaction reads like a classic PE outcome: monetize a mature, de-risked development inventory in the basin’s core to a strategic buyer that can extract additional value through:

• larger-scale development sequencing,

• marketing/transport optimization,

• and cost of capital advantages (investment grade balance sheet).

The hedge book is a key (and underappreciated) part of the deal

Antero emphasized that HG’s production is heavily hedged—approximately 90% of HG natural gas production is hedged in 2026 and 2027 at average NYMEX prices of $4.00 and $3.88, respectively. In practice, that hedge book is a major “financing bridge” that supports near-term free cash flow and helps de-risk leverage targets post-close.

Financing: term loan bridge + free cash flow + Utica proceeds

Antero expects to fund the transaction with a mix of free cash flow, proceeds from the Utica divestiture, and a $1.5 billion underwritten 3-year term loan led by RBC and JPMorgan, with the revolver as additional flexibility.

Pro forma: a step-up in scale, still investment grade

Assuming the HG acquisition and Utica divestiture contribute beginning April 1, 2026, Antero presented a pro forma maintenance production target of ~4.2–4.225 Bcfe/d for 2Q26–4Q26—up from its standalone level of ~3.5 Bcfe/d. The company reiterated an expectation to maintain investment grade ratings and target <1.0x leverage in 2026 based on current strip pricing.

Midstream: Antero Midstream also buying HG’s assets and selling Utica midstream

In a coordinated set of transactions, Antero Midstream (NYSE: AM) agreed to acquire HG’s midstream assets for $1.1 billion and sell its Utica midstream assets for $400 million, further reinforcing the strategic pivot toward the core Marcellus footprint.
