HF Sinclair stock has more than tripled over the past five years, yet its valuation checks still lean cheap, which raises a clear question over how much of that past share price strength is already reflected in today's price. With investors also weighing the planned separation of the Lubricants & Specialties segment and the closure of Canada's largest base oil refinery, the current market value is under close scrutiny.

• HF Sinclair has delivered a 224.8% return over the last five years, which means anyone looking at the stock today is assessing it after a strong multi year run rather than at the start of a story.
• The planned separation of the Lubricants & Specialties segment and the scheduled shutdown of the Mississauga base oil refinery by 2027 can support a sharper focus on core refining and midstream operations, while also introducing execution and transition risks around asset closures and supply reshaping.
• Across Simply Wall St's broader valuation checks, HF Sinclair screens as undervalued in most areas, with 5 of 6 tests indicating the stock looks cheap relative to its fundamentals.

The issue now is whether HF Sinclair's current share price still leaves a margin of value support after this strong five year performance and the announced corporate reshaping.

Is HF Sinclair a Bargain on Earnings?

The P/E ratio is a useful measure for HF Sinclair because earnings are a key anchor for how investors value a refiner. HF Sinclair currently trades on a P/E of about 7.7x, which is well below the Oil and Gas industry average of around 13.2x and also under the broader peer group on roughly 17.4x. That places the stock at a clear discount on earnings compared with many other listed energy companies.

The internal fair P/E for HF Sinclair is estimated at about 9.9x, which is higher than where the stock trades today. This indicates the market is pricing HF Sinclair below a level suggested by its earnings profile, industry position and stated risk assumptions. Despite the recent decision to separate the Lubricants & Specialties segment and close the Mississauga refinery by 2027, the earnings multiple remains materially under both industry and peer benchmarks.

On the P/E multiple, HF Sinclair stock appears undervalued relative to both its fair ratio and sector peers.

The HF Sinclair community is split between those who see room for more value and those who think recent strength already prices in the cycle.

Bull case: roughly fairly valued

Bear case: 24% overvalued

"Accelerating adoption of electric vehicles will steadily reduce demand for gasoline and diesel, undermining HF Sinclair’s core refining revenues and leading to persistent declines in top-line growth as transportation consumption patterns change globally…"

The Bottom Line

HF Sinclair screens as undervalued on earnings, with a P/E discount to both its sector and peer group, and broader valuation checks that point in the same direction. For you the key question is whether this discount reflects mispricing or is the market’s way of accounting for refining cyclicality, the Lubricants & Specialties separation and the Mississauga refinery closure by 2027. The crux of the debate is whether HF Sinclair can sustain earnings quality and capital allocation discipline through that transition so that the current multiple eventually re-rates, or whether the lower valuation simply proves to be the right price for the risks involved.
