Why This High-Yield Pipeline Stock Appears Undervalued After Its 2026 Rally

OneOK represents a compelling opportunity within the infrastructure-focused pipeline stock category. The Tulsa-based midstream operator has delivered solid returns alongside a substantial dividend yield, yet market valuations still suggest room for further appreciation.

Understanding OneOK’s Stable Pipeline Business Model

Operating across 60,000 miles of infrastructure, OneOK functions as a critical intermediary in the energy sector’s transportation ecosystem. Rather than producing energy commodities itself, the company generates revenue through a toll-like fee structure—charging users to transport crude oil, carbon dioxide, natural gas, and natural gas liquids (NGLs) through its extensive network.

This business model creates inherent stability. Long-term contracts with shippers provide predictable cash flows that don’t depend on commodity prices or production volumes. The 120-year operating history demonstrates the durability of this infrastructure-dependent approach. The company’s scale and geographic footprint create a moat that protects margins and ensures continued demand.

Strong Dividend Yield Backed by Strategic Acquisitions

Year-to-date performance has been noteworthy, with the pipeline stock appreciating approximately 18% through early 2026. The current dividend yield of 4.9% sits well above historical averages, rewarding patient investors with substantial income.

OneOK’s recent acquisition strategy has amplified growth prospects. The company acquired Magellan Midstream for $18.8 billion in 2023, followed by Medallion Midstream ($2.6 billion in 2024) and EnLink ($4.3 billion in January 2025). These strategic consolidations expand the pipeline stock’s asset base and revenue-generating potential. Management has committed to annual revenue growth targets of 3-4%, marking the fourth consecutive year of dividend increases.

A critical consideration for yield-focused investors involves dividend safety. While the payout ratio approaches 85%, this metric can be misleading because it includes substantial noncash charges. A more meaningful measure examines how operational cash flows cover dividend distributions. Through the first nine months of 2025, OneOK generated $4.1 billion in operating cash flow while distributing $1.94 billion in dividends—a comfortable 2.1x coverage ratio.

Valuation Analysis: Pipeline Stock Trading at a Discount

Financial momentum has intensified recently. First-nine-month adjusted EBITDA reached $5.9 billion, representing a 27.4% year-over-year increase. Earnings per share climbed 8% to $3.87 during the comparable period.

Near-term expectations show some moderation. Analysts forecast fourth-quarter EPS of $1.50, reflecting a 4% decline year-over-year, with revenues anticipated around $8.9 billion (up 3% annually). Despite this near-term headwind, the pipeline stock’s current valuation around 16 times earnings appears attractive relative to comparable midstream operators. This pricing suggests the market has yet to fully incorporate the earnings power generated by recent acquisitions.

Energy Market Tailwinds Supporting Pipeline Utilization

Current geopolitical dynamics in the Persian Gulf are already supporting crude prices higher. While OneOK doesn’t explore or produce oil, it benefits from elevated energy prices through increased drilling activity. Oil wells produce “associated” natural gas and NGLs alongside crude—commodities that flow through OneOK’s pipeline infrastructure.

Higher drilling rates directly translate to better utilization of the company’s pipeline assets, improving throughput volumes and fee-based revenues. This indirect leverage to oil prices—without commodity exposure risk—represents a distinct advantage for this pipeline stock during periods of energy market strength.

Making the Investment Case Now

Despite analyst projections suggesting lower fourth-quarter earnings, the fundamental case for ownership appears sound. The pipeline stock combines above-average income generation, stable cash flows, and reasonable valuation with near-term catalysts. Infrastructure consolidation trends, operational leverage from recent acquisitions, and current energy market conditions all support potential upside.

For investors seeking exposure to energy infrastructure through a high-yielding pipeline stock, current levels warrant consideration before the market fully reprices these advantages.
