Business Context and Reporting Period
This Current Report on Form 8-K was filed by Antero Midstream Corporation on December 9, 2025. The filing announces a planned private offering of senior notes and details the funding strategy for a major acquisition and asset disposition.
Key Financial Metrics and Capital Structure
- Notes Offering: The Company's subsidiaries, Antero Midstream Partners LP and Antero Midstream Finance Corporation, intend to offer $500 million in aggregate principal amount of senior notes due 2034.
- Existing Debt: As of December 8, 2025, approximately $462 million was outstanding under Antero Midstream Partners' revolving credit facility.

- Transaction Costs: Estimated fees and expenses related to the HG Acquisition and Utica Disposition total approximately $16 million.
Material Changes and Strategic Transactions
The filing outlines a significant capital deployment strategy involving three concurrent but non-contingent events:
- HG Acquisition: Funding the acquisition of HG Energy II Midstream Holdings, LLC from HG Energy II LLC.
- Utica Disposition: Proceeds from the disposition of all Utica Shale midstream assets will be used to fund the acquisition.
- Debt Financing: Net proceeds from the $500 million Notes Offering and borrowings under the revolving credit facility will supplement the acquisition funding.
The completion of the Notes Offering is not contingent on the consummation of the HG Acquisition or the Utica Disposition, and vice versa.
Guidance, Risks, and Contingencies
Special Mandatory Redemption: The Notes include a special mandatory redemption provision. If the HG Acquisition does not close by the "Special Mandatory Redemption Outside Date" (the later of June 2, 2026, or an extended date no later than September 2, 2026), or if the purchase agreement is terminated, the Issuers must redeem all outstanding Notes at 100% of the initial issue price plus accrued interest.
Legal Disclaimer: This filing is not an offer to sell securities. The notes are being offered privately and have not been registered under the Securities Act of 1933.
Investor Verification Checklist
- Verify the final terms and interest rate of the $500 million senior notes due 2034 once the offering is completed.
- Monitor the status of the HG Acquisition and the Utica Disposition to assess the risk of the special mandatory redemption trigger.
- Review the definitive Membership Interest Purchase Agreement for the HG Acquisition to understand extension rights and termination conditions.
- Confirm the actual cash proceeds from the Utica Shale asset disposition versus current estimates.
