Antero Resources acquired the upstream assets of HG Energy II Production Holdings for approximately $2.8 billion in cash, while its affiliated entity, Antero Midstream, separately acquired complementary midstream infrastructure assets from HG Energy for $1.1 billion in cash, bringing the combined enterprise transaction value to roughly $3.9 billion. This massive strategic acquisition significantly expanded the company's core Marcellus Shale acreage footprint in West Virginia, added substantial high-return drilling locations, and extended its overall inventory life while maintaining a disciplined investment-grade balance sheet profile.
