Antero Floats $750M in IOUs to Help Fund Purchase of HG Energy
In December, MDN brought you the news that Antero Resources, the country’s fifth-largest natural gas producer and largest producer in West Virginia, had cut a deal to buy WV driller and midstreamer HG Energy II for a combined (upstream & midstream) $3.9 billion (see Antero Resources Buys HG Energy II in Deal Worth $3.9 Billion). The deal will add a massive 385,000 net acres to Antero’s existing ~475,000 net core Marcellus acreage position, bringing with it another 850 MMcfe/d in production. The same day, we told you that Antero was selling its considerable Ohio Utica assets for $1.2 billion, which will help fund the purchase (see NOG & INR Partner to Buy Antero Resources’ Ohio Utica for $1.2B). The company still needs cash to buy HG Energy, so on Tuesday, Antero announced it will issue a new round of IOUs (“senior notes”) to raise another $750 million.

The bidding war for Ascent Resources continues and gets more complex. Law firm Kirkland & Ellis has been drawn into a dispute between Ascent Resources investors and the private equity firm Energy & Minerals Group (EMG). Mason Capital Management is questioning Kirkland & Ellis’s role representing the Ascent board while also advising EMG in its legal fight with the Abu Dhabi Investment Council. The dispute concerns EMG’s plan to put Ascent into a “continuation vehicle,” which Mason Capital and other investors have opposed. Other companies have since jumped in to make bids to take over Ascent. 
Vickery Energy Partners, LLC, a portfolio company of the private equity firm Quantum Capital Group, announced yesterday that it has closed on the acquisition of Tribune Resources.

Constellation Energy Corporation has finalized its acquisition of Calpine Corporation from Energy Capital Partners, becoming the largest electricity producer in the United States, with a generating capacity of 55 gigawatts. This merger integrates Constellation’s zero-emission nuclear fleet with Calpine’s natural gas and geothermal assets. Prior to the merger, Calpine owned 79 energy facilities across the country, generating some 27 gigawatts (GW) of electricity, with a significant number located in the eastern U.S. Many of Calpine’s facilities use natural gas to produce electricity.

In August 2024, Quantum Capital Group entered into an agreement to acquire Cogentrix Energy, an independent power producer, from another investment firm (Carlyle) for $3 billion (see 
Two weeks ago, MDN brought you the news that Antero Resources, the country’s fifth-largest natural gas producer and largest producer in West Virginia, had cut a deal to buy WV driller and midstreamer HG Energy II for a combined (upstream & midstream) $3.9 billion (see 
The bidding war is heating up for those interested in buying Ascent Resources, a privately held company focused 100% on the Ohio Utica Shale. Ascent is Ohio’s largest natural gas producer and the 8th largest natural gas producer in the U.S. Kimmeridge Energy, a private investment firm focused on the energy sector (sometimes called an “activist investor” and/or corporate raider), has put an offer on the table to buy out and take over Ascent: $6 billion. This is the first hard number we’ve seen since the whole bidding war began last week. 
In October, National Fuel Gas Company, a large utility company headquartered in the Buffalo, NY area with both upstream and midstream subsidiaries (Seneca Resources and NFG Midstream), announced a deal with CenterPoint Energy to acquire CenterPoint’s Ohio natural gas utility business (CNP Ohio) for $2.62 billion (see 
Earlier this year, Houston-based EOG Resources acquired Encino Acquisition Partners for $5.6 billion, establishing the Utica Shale as a “third foundational play” alongside its Permian and Eagle Ford assets (see 
We’ll open this post with this statement: There are no active rumors (that we are aware of) that Permian/Anadarko/Marcellus driller Coterra Energy is considering a merger with Permian/Anadarko/Monteny driller Ovintiv (formerly Encana). We did spot a post by Rystad Energy analysts who theorize that both companies (peers) would make a great combined company. The comments are part of a post titled “US shale braces for next consolidation wave as smaller players seek scale.” Rystad’s theory is that we will soon see smaller independents begin to merge to defend against the recent merger mania by larger companies, including ExxonMobil, Diamondback, Occidental, and ConocoPhillips. 
The second round of big news coming from Antero Resources today is the sale of the company’s Utica Shale assets. We told you in November that Antero, the largest Marcellus/Utica (M-U) driller in West Virginia, officially began to market its Ohio Utica assets for sale (see 
In January, Constellation Energy (a huge power-generating company) announced a deal to buy out and merge with Calpine (another huge power-generating company). Calpine owns 79 energy facilities across the country, generating some 27 gigawatts (GW) of electricity, with a significant number located in the eastern U.S. Many of Calpine’s facilities use natural gas to produce electricity. The two companies combined would own almost 60 GW of nuclear, natural gas, geothermal, hydro, wind, solar, cogeneration, and battery storage. The Federal Energy Regulatory Commission (FERC) signed off on the deal in July, with conditions (see
