Repsol stock (ISIN ES0173516115) was trading at EUR 31.28 on BME on September 28, 2026, up 1.72 percent from the previous close of EUR 30.75. The Spanish energy group has gained 87.19 percent in 2026 through September 23, giving the market move a clear earnings backdrop.

Refining drives first-half earnings

According to Mondo Expat on September 2, 2026, Repsol reported EUR 33.95 billion in first-half 2026 revenue, compared with EUR 27.94 billion in the first half of 2025. That represents an increase of 21.50 percent.

Adjusted net income rose from EUR 1.16 billion to EUR 2.71 billion over the same periods, an increase of 133.62 percent based on the reported figures. The industrial division was the main earnings engine, with adjusted net income increasing from EUR 235 million to EUR 1.68 billion.

Buybacks add a second support

Repsol's investor-relations page lists buyback transactions carried out between September 16 and September 22, 2026, with the communication dated September 23, 2026. The company has framed its capital allocation around shareholder remuneration, financial strength and investment discipline, according to Repsol.

The profit comparison also carries a quality caveat. The first-half figures included a positive inventory effect of EUR 823 million, compared with a negative effect of EUR 394 million a year earlier, so refining margins and inventory accounting both shaped the year-on-year result, as Mondo Expat reported.

Stock sits below the yearly high

At EUR 31.28, Repsol shares were EUR 0.36 below the 52-week high of EUR 31.64 and EUR 20.86 above the 52-week low of EUR 10.42 on September 28, 2026. The market capitalization stood at EUR 34.1 billion, while volume reached 855,217 shares.

Euronews reported on September 24, 2026, that Repsol had gained 87.19 percent in 2026, the strongest performance among the large European energy stocks in its comparison. For investors, the key test is whether refining profitability can remain strong enough to support earnings after the inventory effect fades.
