ONEOK (OKE) Stock Still Looks Like A Bargain On Cash Flow

Trade ONEOK on Coinbase

ONEOK stock has delivered strong multi year gains, yet the current valuation picture is more nuanced, with recent returns and the broader checks not lining up as a simple bargain or an obvious stretch.

  • Over the past 5 years, ONEOK has returned 133.5%, which puts more focus on whether the current price already reflects much of the progress investors have been paying for.

  • For a pipeline and midstream focused business like ONEOK, expectations for steady cash generation can support the current share price. At the same time, exposure to volume swings and funding needs for large projects may weigh on how much investors are willing to pay.

  • The broader valuation framework points to a mixed picture rather than a clear bargain or clear overvaluation. The company screens on the cheaper side in 4 of 6 checks according to its value score of 4 .

For investors, the debate is whether ONEOK's recent share price strength already reflects the key cash flow and risk factors or whether the current multiples still leave room for further upside over time.

Is ONEOK Still Cheap on Earnings?

The P/E ratio is a useful way to think about what you are paying today for each dollar of ONEOK earnings. It links directly to the company focus on steady profit generation from its pipeline and midstream assets.

ONEOK currently trades on a P/E of about 16.3x. That is higher than the broader Oil and Gas industry average of roughly 12.7x, so the stock does not screen as cheap against the sector as a whole. However, it sits below the peer group average of about 18.7x, which indicates investors are paying less for each dollar of earnings than for similar companies.

The tailored fair P/E ratio for ONEOK is estimated at about 22.2x. This is meaningfully above the current 16.3x level, which points to a discount relative to what the model suggests might be justified given the company profile and risk factors.

Overall, ONEOK stock appears undervalued on the P/E multiple compared with both its peer group and the model based fair ratio.

The ONEOK Narrative: What Would Justify Today's Price?

Bull case: 12% undervalued

"The build-out of large-scale, integrated midstream infrastructure in cost-advantaged U.S. shale basins, alongside dedicated acreage and increased control over Delaware Basin operations, gives ONEOK a structural cost and market access advantage that should meaningfully increase fee-based revenues, protect margins, and accelerate free cash flow growth..."

Bear case: 8% overvalued

"Despite renewable demand remaining a slow threat in the near term, the long-term pace of technology innovation and cost improvements in renewables and battery storage could accelerate displacement of natural gas in the power and industrial sectors, ultimately eroding pipeline utilization rates and reducing revenue visibility for ONEOK's core assets..."

The Bottom Line

ONEOK screens as undervalued on key market multiples, yet the broader checks still point to a mixed picture rather than a clear-cut bargain. For you as an investor, the core issue is whether the current earnings power and the balance of risks around project funding and volume exposure justify any valuation gap that remains.

The debate now largely turns on one assumption: either ONEOK continues to generate the reliable cash flows that support its current earnings multiple, or long term energy transition and utilization risks indicate that the current discount is there for a reason.
