Matador’s Midstream Power Play: A $752M Bet on Delaware Basin Control

DALLAS, TX – June 29, 2026 – In a move that signals a significant consolidation of energy infrastructure in one of America's most productive oil and gas regions, Matador Resources Company announced that its midstream joint venture, San Mateo Midstream, will acquire Cardinal Midstream for $752 million. The all-cash deal is more than a simple expansion; it represents a calculated maneuver to build a dominant, integrated system for moving natural gas, oil, and water across the northern Delaware Basin, a landscape where pipeline capacity is king.

San Mateo, a 51-49 joint venture between producer Matador and infrastructure specialist Five Point Infrastructure, is acquiring a complementary set of assets that will significantly bolster its operational footprint. The transaction underscores a broader trend where exploration and production companies are leveraging sophisticated midstream partnerships not just to service their own wells, but to build powerful, self-funding businesses that reshape regional energy flows.

"Completing the Circle": A Strategic Infrastructure Buildout

The core of the deal’s logic lies in the concept of “flow assurance”—a term that, for producers, means the difference between profit and stranded assets. In the complex plumbing of the Delaware Basin, the ability to reliably move natural gas from the wellhead to processing plants and on to major markets is paramount. This acquisition is engineered to deliver exactly that.

Cardinal Midstream brings a critical set of assets to the San Mateo network, including a cryogenic natural gas processing plant in Loving County, Texas, with a capacity of 320 million cubic feet per day (MMcf/day), and approximately 145 miles of gathering pipelines. When integrated, these assets will create a system with formidable scale: San Mateo’s total natural gas processing capacity will surge to over one billion cubic feet per day (Bcf/day), supported by a sprawling network of more than 800 miles of pipeline.

Joseph Wm. Foran, Matador’s Founder and CEO, described the strategic fit as effectively “completing the circle” for San Mateo’s infrastructure. The combined system will grant the company the flexibility to route natural gas north-to-south or south-to-north between its Black River and Marlan plants in New Mexico and the newly acquired Cardinal plant in Texas. This interconnectivity creates redundancy and optionality, minimizing bottlenecks and ensuring that gas from Matador and other customers keeps flowing even if one part of the system faces constraints. This level of system flexibility, as Foran noted, is something “few midstream providers can match.”

This enhanced assurance directly supports Matador’s own growth ambitions. The company plans to use the expanded network to service its development on recently acquired federal lease acreage in Lea County, New Mexico, and its Wolf asset area in Loving County, Texas. By controlling a larger, more robust midstream system, Matador de-risks its own upstream investments, ensuring its future production has a guaranteed path to market.

Midstream Money for Midstream Deals

Beyond the operational synergies, the transaction is a case study in modern energy finance. Matador has structured the deal so that the significant $752 million price tag is expected to be “cash neutral” for the parent company. This financial architecture allows Matador to fuel major growth in its midstream segment without straining its own balance sheet or diverting capital from its primary business of drilling wells.

The financing is led by a new term loan of up to $650 million under San Mateo’s existing credit facility. Notably, this loan has a 364-day maturity, acting as a short-term bridge. This suggests that the company and its partners are not planning to carry this debt long-term, but are instead positioning San Mateo for a subsequent, more permanent capital event. The remainder of the purchase price will be covered by cash on hand and capital contributions from the partners.

Matador’s contribution will be funded by what Foran calls “midstream money.” The company expects to use cash distributions it receives from the profitable San Mateo venture itself, or proceeds from the potential sale or “drop-down” of other wholly-owned midstream assets into the joint venture. This creates a virtuous cycle: the midstream business generates cash, which is then used to acquire more midstream assets, which in turn generate more cash and increase the venture’s overall value. This strategy is underpinned by Matador's robust financial health, with projections of over $1.1 billion in free cash flow for 2026 and a recently paid-down credit facility, giving it immense flexibility.

Expanding Influence and Positioning for the Future

This acquisition is not merely defensive; it is an offensive move to capture a larger share of the lucrative third-party midstream market in the Delaware Basin. The deal immediately brings nine new natural gas customers from Cardinal’s portfolio into the San Mateo fold. This diversifies San Mateo’s revenue streams, reducing its reliance on Matador’s volumes and proving its competitiveness in the open market. The increased third-party business is a key driver behind the projection that the Cardinal assets will generate up to $110 million in annualized Adjusted EBITDA by 2028.

The expanded scale and diversified customer base do more than just boost current cash flow; they set the stage for San Mateo’s “next chapter.” Company leadership explicitly stated that the transaction improves San Mateo’s “positioning for potential strategic alternatives at the corporate level.” The short-term bridge loan is a strong indicator of this intent. Industry observers suggest this could pave the way for several value-unlocking possibilities, including an Initial Public Offering (IPO) of San Mateo, a partial sale to another strategic or financial partner, or using the newly enlarged platform to further consolidate smaller players in the basin.

Since its formation in 2017, San Mateo has evolved from a startup into what Foran calls “one of the premier midstream businesses in the northern Delaware Basin.” By acquiring Cardinal, Matador and Five Point are not just buying pipes and plants; they are buying scale, market share, and strategic options, transforming their joint venture into a formidable infrastructure player ready for its next major move.
