The accelerating global energy transition, driven by increased adoption of renewable energy and electrification, represents a clear emerging threat by potentially reducing long-term demand for the fossil fuels transported and processed by Summit Midstream. This trend is amplified by increasing regulatory scrutiny and permitting challenges for new fossil fuel infrastructure, coupled with growing pressure from investors and lenders to de-emphasize fossil fuel assets.

Summit Midstream (SMC) operates in the midstream energy sector, primarily focusing on natural gas, crude oil, and produced water services within the continental United States. The addressable markets for their main products and services are sized as follows:

• Natural Gas Gathering, Processing, and Transportation: The U.S. gas pipeline infrastructure market, which includes gathering pipelines, was valued at approximately USD 1,058.73 billion in 2024. This market is projected to reach around USD 2,431.55 billion by 2034, exhibiting a Compound Annual Growth Rate (CAGR) of 8.67% between 2025 and 2034. The gathering pipelines segment specifically is expected to experience the fastest growth due to increasing shale gas production.
• Crude Oil Gathering: The broader U.S. oil and gas infrastructure market, which encompasses gathering activities, was valued at USD 78.9 billion in 2024. It is projected to grow at a CAGR of 6.4% from 2025 to 2034.
• Produced Water Gathering and Treatment: The U.S. water and wastewater treatment market, which includes the treatment of produced water from oil and gas operations, was valued at USD 121.85 billion in 2024. This market is expected to reach approximately USD 238.36 billion by 2034, growing at a CAGR of 6.94% over the forecast period from 2025 to 2034.

Summit Midstream (SMC) is expected to experience future revenue growth over the next 2-3 years driven by several key factors:

1. Strategic Acquisitions and Integration: Summit Midstream has recently completed significant acquisitions, including the Tall Oak transaction in December 2024 and the Moonrise acquisition in March 2025. These acquisitions are anticipated to expand the company's operational capacity and flexibility, contributing to increased throughput volumes. The ongoing integration of these acquired assets is expected to continue supporting operating cash flow and overall revenue.

2. Increased Well Connections and Producer Activity: The company has a strong focus on connecting new wells and benefiting from ongoing producer development programs. Summit Midstream completed 47 new well connections in the first half of 2025 and 109 year-to-date as of the third quarter of 2025. Projections indicate approximately 50 additional wells are expected to be connected in the fourth quarter of 2025, with more than 120 new well connections anticipated in the first half of 2026. This sustained customer activity, particularly in the Rockies and Mid-Con segments, is a direct driver of increased volume throughput.

3. Long-Term Contract Extensions and New Commercial Agreements: Summit Midstream has secured key commercial agreements that are set to drive stable revenue. Notably, the company executed a new 10-year extension of certain gathering agreements with a major customer in the Williston Basin, which significantly increases its weighted average contract life. Additionally, a new 10-year precedent agreement for 100 million cubic feet per day of firm capacity on the Double E pipeline in the Permian region, with an in-service date targeted for Q4 2026, is expected to provide substantial new revenue.

4. Volumetric Growth in Core Operating Basins: The company anticipates volumetric increases across its key operating regions. In the Arkoma Basin, a primary customer commenced a 20-well drilling program that is projected to drive 5% to 10% volumetric growth in 2026. The Rockies segment, encompassing the DJ and Williston Basins, experienced a 7.5% quarter-over-quarter increase in natural gas volumes in Q3 2025 due to ongoing development. Similarly, the Mid-Con segment saw a 2.9% rise in volume throughput and higher natural gas sales in Q2 2025, largely attributed to new well connections and the Tall Oak acquisition.
