Sunoco (SUN) Following Oil Supply Disruption Looks Close To Fair Value

Simply Wall St · 2d ago

U.S.-based oil and gas stocks are having a record year as the war in Iran disrupts global supplies, and Sunoco (SUN) has joined the move, with the stock up more than 50% in 2026.

For Sunoco, that surge has come with steady momentum rather than a single spike, with a 27.3% 3‑month share price return and a 69.95% 1‑year total shareholder return. This suggests investors are repricing the stock as war related supply risks keep U.S. fuel distributors in focus.

After a run like this, some investors will want to lock in Sunoco exposure now, while others prefer to wait for a calmer entry. The valuation work below helps frame that trade off.

Most Popular Narrative: 3% Undervalued

On the most followed narrative, Sunoco’s fair value sits at about $83, just above the last close at $79.97. This frames the recent surge as roughly in line with updated cash flow expectations rather than disconnected momentum.

Sunoco's consistent expansion through organic projects and roll-up acquisitions in a highly fragmented fuel distribution market, where over 60% of participants are small, single-store operators, positions the partnership to capture additional market share over time, supporting sustained revenue and EBITDA growth. Management and external analysts see the NuStar and pending Parkland and TanQuid transactions as materially accretive to earnings, with cost and operating synergies expected to increase operating leverage, widen net margins, and extend Sunoco's reach beyond its traditional U.S. footprint.

See why 17 investors see Sunoco as 3% undervalued.

Result: Fair Value of $83 (UNDERVALUED)

Still, the Sunoco story can break if long term gasoline demand drifts lower, or if acquisition leverage and integration issues start to pressure earnings.
