Forget Occidental Petroleum. Buy This Pipeline Stock in September Instead.

Williams Companies is presented as a more defensive energy investment than Occidental Petroleum, with a 2.8% forward dividend yield, a 25% year-to-date share gain, and a valuation below 13x next year's adjusted EBITDA. Williams transported roughly 30% of U.S. natural gas and is expanding behind-the-meter natural-gas systems for data centers, which can be deployed in 18-24 months versus 4-7 years for grid connections. First-half 2026 AFFO rose 17% year over year to $3.2 billion, covering dividends by 2.5x, while analysts project 7% adjusted-EBITDA CAGR for 2025-2028.

Analysis

The relevant relative-value question is not WMB versus OXY in isolation, but whether incremental data-center power demand can tighten Northeast gas basis and raise Transco utilization faster than the market has modeled. WMB’s contracted cash flows should support a lower beta profile, but AI-related upside requires signed capacity, rate-base-like returns on behind-the-meter deployments, and creditworthy hyperscaler counterparties; otherwise the “AI infrastructure” label risks becoming a multiple-expansion story without material EBITDA acceleration.

OXY remains the higher-torque expression of sustained geopolitical oil disruption, but its equity upside is increasingly dependent on crude remaining elevated rather than on volume growth. A sharp oil reversal would compress upstream cash generation and capital-return capacity more quickly than WMB’s fee-based earnings, while WMB is exposed to a different risk: lower gas demand from a recession, project delays, and rising financing costs reducing the value of its long-duration growth backlog.

Near term, retail-oriented commentary is unlikely to create a durable catalyst after WMB’s strong run. Over the next 1-3 months, watch announced hyperscaler power contracts, Transco expansion permitting, Appalachian/Haynesville production commitments, and winter gas spreads. Over 6-18 months, the key structural issue is whether gas-fired distributed generation becomes a bridge solution before utility interconnection queues clear; that would favor WMB, ENB, KMI and select gas generators, but could invite regulatory scrutiny over emissions and local permitting.

Contrarian view: WMB’s defensive/AI narrative may already be crowding a stock historically owned for yield, leaving less upside if EBITDA growth merely meets expectations. The cleaner asymmetric trade may be long WMB versus short a more oil-sensitive producer only while crude remains vulnerable to a de-escalation-driven decline; do not assume midstream is commodity-proof, as producer activity ultimately determines throughput and expansion economics.

Key Decisions for Investors

• Initiate a 3-6 month relative-value position: long WMB / short OXY, dollar-neutral. Thesis is cash-flow durability and gas-power optionality versus OXY’s greater sensitivity to a crude pullback; target 10-15% relative outperformance. Exit if WTI sustains above $100/bbl with escalating supply disruption, or if WMB discloses material BTM project slippage.
• Do not add outright WMB aggressively at current momentum; accumulate only on a 7-10% pullback or following independently verifiable contracted-capacity awards. Require evidence that new data-center-related projects are accretive to EBITDA rather than merely announced development opportunities.
• Maintain OXY only as a tactical oil hedge, preferably through defined-risk calls or a small USO/XLE overlay rather than unhedged equity exposure. Reassess after the next earnings update for capital-return guidance, realized-price sensitivity, and any change in production or debt-reduction priorities.
• Set alerts for Transco expansion approvals, hyperscaler BTM contract disclosures, and Henry Hub forward-curve strengthening. Positive confirmation supports increasing WMB; a weakening gas curve combined with producer capex cuts would falsify the throughput-growth component of the thesis.
