Here are the 424B prospectus supplements from Antero Resources Corporation (AR) in our archive over the last 12 months, newest first, and each one links through to the document itself with the summary and the scores our analysis gives it.
A 424B covers the supplement that carries the terms of a priced offering, so if you follow AR and want that one kind of document rather than the whole filing history, this is the page to keep. The company's other filings, of every form, are on the full AR filings page.
Antero Resources Corporation is issuing $750,000,000 of 5.400% senior notes due 2036 to help finance its pending HG Acquisition. The notes pay interest semi-annually on February 1 and August 1, starting August 1, 2026, and mature on February 1, 2036. They are senior unsecured obligations, ranking equally with Antero’s other senior unsecured debt and structurally subordinated to liabilities at its subsidiaries.
Antero expects net proceeds of about $743 million, which, together with a proposed $1.5 billion three-year Term Loan A and proceeds from an $800 million Utica Shale asset sale, will fund the $2.8 billion purchase of HG Energy II Production Holdings and related costs. If the HG Acquisition does not close by the specified outside date, or the purchase agreement is terminated, the company must redeem all notes at 101% of principal plus accrued interest under a special mandatory redemption provision.
The filing notes that, after giving effect to the notes, the Term Loan A and the Utica Disposition, total indebtedness would be approximately $3.3 billion as of September 30, 2025. HG Production’s assets include about 385,000 net Marcellus acres and roughly 700 MMcfe/d of net production, which is expected to extend Antero’s drilling inventory by over five years at maintenance capital levels.
Antero Resources plans to issue new senior unsecured notes due 2036, with fixed semi-annual interest, to help finance a large acquisition in the Appalachian Basin. The notes rank equally with Antero’s other senior unsecured debt, are structurally subordinated to subsidiary liabilities, and can be redeemed early at specified prices, including a make-whole call and a par call close to maturity.
Net proceeds, together with borrowings under a proposed $1.5 billion Term Loan A, are intended to fund the $2.8 billion HG Acquisition of HG Energy II Production Holdings, which adds roughly 385,000 net Marcellus acres and over 400 drilling locations. Antero also has an $800 million Utica Disposition pending to help fund the transaction and potentially repay debt.
If the HG Acquisition does not close by the Special Mandatory Redemption Outside Date, if the purchase agreement is terminated, or if Antero concludes it will not close, the company must redeem all notes at 101% of principal plus accrued interest. Key risks highlighted include higher leverage, dependence on commodity prices and capital markets, integration risks for the HG assets, and the possibility that the acquisition or disposition is delayed or not completed.
