The primary clear emerging threat to ONEOK (OKE) is the accelerating global energy transition and decarbonization efforts, which directly challenge the long-term demand for the fossil fuels (natural gas, natural gas liquids, and crude oil) that constitute the core of the company's midstream transportation and processing business. This transition, analogous to how new technologies or business models have disrupted incumbents historically, manifests through:

• The increasing cost-effectiveness and widespread adoption of renewable energy sources (e.g., solar, wind) for power generation, which displaces demand for natural gas.
• Aggressive policy initiatives and regulatory frameworks globally, including carbon pricing and emissions reduction mandates, incentivizing reduced reliance on fossil fuels.
• Significant growth in electric vehicle adoption and battery storage solutions, which collectively decrease long-term demand for crude oil and potentially natural gas.
• Rising investor and public pressure for environmental sustainability, leading to reduced capital availability and increased scrutiny for new fossil fuel infrastructure projects.

• Natural Gas Liquids (NGLs): The North American Natural Gas Liquids market was estimated at USD 7.08 billion in 2024 and is projected to grow to USD 11.53 billion by 2033, demonstrating a compound annual growth rate (CAGR) of 5.57%. Specifically within the U.S., the NGL market had a size of USD 5,536.32 million in 2024. The global natural gas liquids market was valued at USD 23.38 billion in 2024 and is projected to reach USD 43.04 billion by 2035, growing at a CAGR of 5.70%.
• Natural Gas Gathering and Processing: The global gas processing market was valued at USD 228.66 billion in 2024 and is projected to surpass USD 430.84 billion by 2034, with a CAGR of 6.54%. North America holds the largest share in the global gas processing market, with the U.S. being a significant contributor.
• Natural Gas Pipelines: The U.S. gas pipeline infrastructure market was valued at USD 1,149.26 billion in 2025 and is projected to reach approximately USD 2,431.55 billion by 2034, growing at a CAGR of 8.67% between 2025 and 2034. The broader North American gas pipeline infrastructure market was valued at US$ 21,084.52 billion in 2022, with projections to reach US$ 27,641.34 billion by 2030, at a CAGR of approximately 3.4%.
• Refined Products and Crude Oil Transportation: Information specifically sizing the U.S. or North American market for refined products and crude oil *transportation via pipelines* (as a distinct market segment from overall crude oil or refined product markets) was not readily available in the provided search results. Therefore, it is not possible to size this specific addressable market based on the current information.

ONEOK (OKE) is poised for future revenue growth over the next 2-3 years, driven by several strategic initiatives and expansions across its diversified energy infrastructure. Key drivers include significant investments in natural gas liquids (NGL) infrastructure, expansion of refined products pipelines, realization of synergies from recent acquisitions, and growth in natural gas gathering and processing volumes.

Here are the expected drivers of future revenue growth for ONEOK:

1. NGL Infrastructure Expansions: The completion and ramp-up of major NGL infrastructure projects, such as the MB-6 NGL fractionator in Mont Belvieu, Texas, and the full looping of the West Texas NGL Pipeline system, are significant drivers. The MB-6 fractionator has increased ONEOK's total fractionation capacity to over 1 million barrels per day (bpd), reducing reliance on third-party facilities. The West Texas NGL Pipeline system's capacity has expanded to 515,000 bpd, with further expansion to 740,000 bpd expected by mid-2025 through additional pump stations. These expansions are critical for meeting growing NGL market demand and enhancing operational control.
2. Refined Products Pipeline Expansion to Denver: ONEOK is expanding its refined products pipeline capacity to the greater Denver area. This project, involving a new 230-mile pipeline from Scott City, Kansas, to Denver International Airport (DIA) and upgrades to existing pump stations, is expected to be completed by mid-2026. It will increase total system capacity by 35,000 bpd and is aimed at meeting the rising demand for refined products and renewable fuels, including aviation and sustainable aviation fuel, in the Denver region.
3. Synergies from Strategic Acquisitions: The integration of recent acquisitions, including Medallion Midstream and EnLink assets, is a substantial driver of future revenue growth. These acquisitions have already contributed significantly to adjusted EBITDA, with the acquired EnLink and Medallion assets delivering nearly $470 million in adjusted EBITDA in Q3 2025. ONEOK aims to achieve $870 million in synergies and growth by 2026, and projects this to reach $1.3 billion by 2027, by expanding its crude oil gathering and transportation infrastructure in the Permian Basin and strengthening its position in the natural gas and NGL sectors.
4. Increased Natural Gas Gathering and Processing Volumes: Growth in natural gas gathering and processing volumes, particularly in key production basins like the Permian (Delaware and Midland basins) and Rocky Mountain regions, is expected to boost revenue. ONEOK is actively expanding its natural gas processing capacity, including a new processing plant in the Delaware Basin scheduled for completion by mid-2027, to support increasing production from producers.
