The key risks to Antero Midstream's business include a significant reliance on Antero Resources, indirect exposure to commodity price fluctuations, and regulatory and environmental challenges.

1. Customer Concentration Risk: Antero Midstream's business is highly dependent on Antero Resources Corporation ("Antero Resources"), its primary customer and affiliated producer. Substantially all of Antero Midstream's revenue is derived from Antero Resources, as its gathering and processing segment collects and processes production from Antero Resources' wells. This reliance means that any operational or financial challenges faced by Antero Resources, such as reduced drilling activity or production declines, would directly and materially impact Antero Midstream's cash flow, revenue, and growth prospects.
2. Indirect Exposure to Commodity Price Fluctuations: Although Antero Midstream largely operates under fixed-fee contracts, its volumes and, consequently, its revenue are indirectly tied to the production activities of Antero Resources, which are influenced by natural gas and natural gas liquids (NGL) prices. A sustained period of low commodity prices could compel Antero Resources to decrease its drilling and development plans, leading to reduced production volumes. Such a reduction in volumes would directly impact the demand for Antero Midstream's gathering, processing, and water handling services.
3. Regulatory and Environmental Risks: As an owner and operator of midstream energy infrastructure, Antero Midstream is subject to extensive and evolving environmental, social, and governance (ESG) regulations. Changes in environmental laws, increased regulatory scrutiny, or stricter permitting requirements for pipeline construction and operation could lead to delays, increased compliance costs, or even project cancellations. Furthermore, the company faces potential litigation risks related to climate change and could experience impacts on its access to capital if financial institutions adopt policies reducing funding to the fossil fuel sector.

Clear Emerging Threats for Antero Midstream (AM):

• Accelerating Energy Transition and Decarbonization: The global shift towards renewable energy sources, energy storage advancements, and decarbonization policies represents a significant emerging threat. As demand for natural gas potentially declines due to these trends, the long-term throughput and value of Antero Midstream's natural gas gathering and processing infrastructure could be diminished. This could lead to underutilized assets and reduced opportunities for expansion.
• Increased On-site Water Recycling and Management by Upstream Operators: Upstream energy producers, including Antero Resources, are increasingly investing in and implementing advanced technologies for on-site water recycling, treatment, and reuse. This trend reduces their reliance on third-party services for fresh water delivery and disposal, directly threatening the demand for Antero Midstream's water handling services.

Antero Midstream (AM) Addressable Market Sizes

• Natural Gas Gathering and Processing: The Appalachian Basin, encompassing West Virginia and Ohio, is the largest natural gas-producing region in the United States. In 2025, natural gas production in the Appalachian Basin reached 36.6 billion cubic feet per day (Bcf/d). The natural gas processing capacity across Kentucky, Ohio, Pennsylvania, and West Virginia is projected to increase by 2.5 Bcf/d over the next few years. The overall U.S. oil and gas midstream market, which includes gathering and processing, was valued at approximately USD 17.10 billion in 2025 and is projected to grow to USD 21.08 billion by 2031.
• Water Handling Services (for oil and gas operations): The U.S. midstream water market for oil and gas is projected to reach a total of USD 156 billion between 2025 and 2030, averaging over USD 26 billion annually. North America holds approximately 45% of the global market share for oil and gas water management services. While the Permian Basin dominates U.S. midstream water spending, the Appalachian Basin remains strategically important for natural gas production.

Antero Midstream Corporation (AM) is expected to drive future revenue growth over the next two to three years through a combination of increased throughput, strategic acquisitions, and infrastructure expansion within its core operating areas.

The key drivers for Antero Midstream's future revenue growth include:

• Increased Gathering and Processing Volumes from Antero Resources: A primary driver of revenue growth for Antero Midstream is the anticipated increase in gathering and processing volumes from its anchor customer, Antero Resources (AR). Antero Resources' multi-decade drilling inventory is expected to support sustained production, which in turn will drive demand for Antero Midstream's gathering, compression, and processing services. For instance, in Q3 2023, low-pressure gathering volumes increased by 13% year-over-year, with approximately 6% organic growth, and processing volumes set a company record in Q1 2025. The company anticipates low to mid-single-digit year-over-year growth in gathering volumes for 2025.
• Strategic Acquisitions and Integration: The recent acquisition of HG Midstream for $1.1 billion is a significant driver, adding over 400 undeveloped locations dedicated to Antero Midstream. This acquisition is expected to provide a substantial addition to the company's asset base and future development projects, contributing to EBITDA and free cash flow growth in fiscal year 2026 and beyond. The integration of the acquired water assets is also projected to lead to further growth in the water business starting in 2027.
• Expansion of Rich Gas Gathering System and Dry Gas Infrastructure: Antero Midstream plans capital investments in high rate-of-return infrastructure projects within the Marcellus Shale. These include the buildout of its rich gas gathering system and new expansion projects aimed at supporting additional dry gas growth on dedicated acreage. These initiatives are designed to provide incremental market opportunities and unlock further development optionality across Antero Midstream's diverse portfolio of rich and dry gas assets.
• Growth in Water Handling Services: Beyond the integration of acquired assets, Antero Midstream's Water Handling segment is expected to continue growing. The company forecasts servicing 65 to 75 wells with its fresh water delivery system in 2026, primarily for Antero Resources' legacy acreage completions, before fully integrating and expanding services on the newly acquired HG acreage in 2027 and subsequent years.

Share Repurchases

• Antero Midstream repurchased 2.7 million shares for $48 million during the fourth quarter of 2025.
