Summit Midstream SEC Filings

Summit Midstream Corporation filed a current report describing strong commercial momentum on two key growth platforms: the Double E natural gas pipeline in the Permian and its crude oil gathering systems in the Williston Basin.

For Double E, the company has executed three new long-term firm transportation agreements totaling 250 MMcf/d during a binding open season and entered into a firm option agreement for an additional 200 MMcf/d. With these commitments and an affirmative FID notice tied to a prior 230 MMcf/d agreement, Double E’s total contracted firm capacity has risen to about 1.9 Bcf/d. The planned Compression Expansion would increase pipeline capacity by roughly 50%, from about 1.6 Bcf/d to about 2.4 Bcf/d, with a targeted in-service date at the end of 2028.

In the Williston Basin, Summit signed a new crude oil gathering agreement in Divide County, North Dakota, covering a 40,000-acre area of dedication and supporting 15 new four-mile lateral well connects expected by year-end 2026. Management notes that, over the past six months, dedicated crude gathering acreage has expanded by more than 240,000 acres as development activity migrates toward the company’s existing footprint.

Summit Midstream Corporation announced that its Board of Directors has authorized an inaugural stock repurchase program to buy back up to $35 million of its outstanding common stock. This gives the company flexibility to return capital to shareholders when it views the share price as attractive.

Management highlighted that all arrears on the Series A Preferred Stock have been repaid and that improving free cash flow and financial flexibility support the decision. Repurchases may be made in the open market or through privately negotiated and block transactions, including under a Rule 10b5-1 trading plan, and can be started, paused, or discontinued at management’s discretion with no fixed end date.

Summit Midstream Corp director Jerry L. Peters reported an open-market sale of 10,000 shares of Common Stock at $32.00 per share through a Joint Spousal Trust. The transaction was reported as an indirect ownership change.

Following this sale, the Joint Spousal Trust held 16,979 Summit Midstream Corp shares attributable to Peters.

Charles Schwab Corporation submitted a Form 144 notice relating to the proposed sale of 10,000 shares of Common Stock. The filing lists an aggregate amount of $317,000.00 and includes multiple prior director compensation equity grants dated 03/15/2022, 03/15/2023, 03/14/2025, and 03/16/2026 with share counts shown. The filing identifies the exchange as NYSE.

Summit Midstream Corporation held its 2026 annual meeting of stockholders on May 7, 2026, where investors voted on five proposals. Holders of common and Class B common stock voted together on most items, while Class B stockholders voted separately on one director seat.

Stockholders elected three Class II directors and one Class II Class B director to serve until the 2029 annual meeting. They also ratified Deloitte & Touche LLP as independent registered public accounting firm for the year ending December 31, 2026, approved an advisory resolution on executive compensation, and approved Amendment No. 1 to the Summit Midstream Corporation 2024 Long-Term Incentive Plan.

Summit Midstream Corporation reported a small loss for the first quarter of 2026 but kept its full-year outlook intact. The company posted a net loss of $3.2 million, compared with net income of $4.6 million a year earlier, as operating costs and interest expense offset modest revenue growth.

Adjusted EBITDA was $54.2 million, down from $57.5 million, with Distributable Cash Flow of $26.9 million and Free Cash Flow of $11.4 million. Natural gas throughput on wholly owned systems slipped to 870 MMcf/d and liquids volumes to 64 Mbbl/d, while the Double E Pipeline averaged 805 MMcf/d and contributed $8.7 million of Adjusted EBITDA.

The company highlighted a new 100 MMcf/d, 10‑year firm capacity agreement on Double E and reiterated 2026 Adjusted EBITDA guidance of $225 million to $265 million. Liquidity remained solid with $43.4 million of cash and $381 million of ABL borrowing availability, and Summit was in compliance with leverage and interest coverage covenants. Summit repaid all $45–46.3 million of accrued Series A preferred dividends and completed a $42 million private placement of common stock, but the board continued to suspend the common dividend.

Summit Midstream Corporation reported a Q1 2026 net loss and executed major balance sheet moves. Total revenues rose to $139,142 (thousand dollars) from $132,697, driven mainly by higher natural gas, NGL and condensate sales, while net income swung to a loss of $3,166 (thousand dollars) from a $4,634 profit a year earlier.

Net loss attributable to common shareholders widened to $5,295 (thousand dollars), or $0.43 per share, versus a $0.16 loss. Operating cash flow fell to $6,870 (thousand dollars), but cash and restricted cash increased to $49,522 (thousand dollars) as the company refinanced its Permian credit facilities with a $440,000 (thousand dollars) New Permian Transmission Facility, redeemed $143,226 (thousand dollars) of Subsidiary Series A Preferred Units, paid $49,416 (thousand dollars) of Series A Preferred dividends including $46,300 (thousand dollars) in arrears, and raised $41,459 (thousand dollars) via a related-party equity issuance.

The filing attributes these holdings to certain Reporting Business Units of BlackRock and shows sole voting power for 602,656 shares and sole dispositive power for 612,798 shares.
