Repsol (BME:REP) Could Be 40% Undervalued As Valuation Views Split

Listen to the news

Repsol (BME:REP) has drawn fresh attention after its recent share price move, with the stock closing at €29.38. That shift puts the current performance and the wider multi-energy business mix back in focus for investors.

For context, Repsol’s recent 1-month share price return of 9.67% and 90-day gain of 34.65% point to building momentum. The 79.04% year-to-date share price return and 107.03% 1-year total shareholder return indicate that this latest move extends a much stronger run rather than breaking a quiet stretch.

Repsol’s surge has already rewarded holders in a big way, yet the share price still screens at a sizeable intrinsic discount. Is most of the upside already in the rear-view mirror, or does the valuation still leave room on the table?

Most Popular Narrative: 6% Overvalued

The most followed narrative puts Repsol’s fair value at €27.63, which sits below the last close of €29.38. That gap frames the current rally as slightly ahead of the underlying valuation work rather than lagging it.

Repsol's continued expansion and asset rotations in renewable energy (notably wind, solar, and renewable fuels) are poised to diversify revenue streams, lessen earnings volatility, and capture higher-margin growth in low-carbon markets; this is strengthened by increasing policy support for renewables and rising demand in both the U.S. and Spain, directly impacting future revenue and net margins.

See why 76 investors see Repsol as 6% overvalued.

The fair value estimate is built using a 7.4% discount rate and assumes revenue growth of about 2.35% a year in euro terms with future net profit margins near 5.65%. That framework also applies a future P/E of roughly 9.15x on those earnings, which is slightly lower than the previous multiple used in this narrative.

Analysts feeding into this view are effectively saying the current price already reflects much of Repsol’s multi-energy repositioning, while still assigning value to the renewable and low carbon projects described in the narrative. The modest revision of fair value from €27.08 to €27.63, alongside a share price above both levels, points to limited implied upside within this specific model at today’s quote.

Result: Fair Value of €27.63 (OVERVALUED)

Still, any acceleration in carbon pricing or a slower shift into renewables than analysts expect could pressure Repsol’s cash generation and challenge this valuation story.
