Enagas (ISIN ES0130960018) was trading at EUR 16.53 at Lang & Schwarz on October 12, 2026 at 9:12 a.m. CEST. On October 5, 2026, the company completed permanent sealing of 13 Castor wells at an estimated EUR 241.00 million cost, while the quote stood 7.86 percent below its EUR 17.94 52-week high. Enagas published the Castor update on October 5, 2026.

Castor work costs EUR 241 million

The Castor operation installed three permanent plugs in each well and left the facility ready for the final dismantling phase. The estimated EUR 241.00 million cost remains subject to final certifications, making the project a material infrastructure item rather than a routine operating update.

The completed work covered eight production wells, four monitoring wells and one fluid reinjection well. The company also reported that the well casings were cut more than three meters below the seabed, a technical step designed to clear the marine floor.

What does Castor mean for Enagas?

The immediate investor question is the balance between this one-off infrastructure obligation and the earnings profile of the regulated gas network. Investisseurs Heureux reported second-quarter 2026 revenue of EUR 226.00 million, down 9.40 percent from the same quarter a year earlier.

That comparison gives the Castor cost a useful scale: EUR 241.00 million is higher than the company's EUR 226.00 million second-quarter revenue, although the two figures describe different items and periods. For investors, the key distinction is between a project cost tied to abandonment work and recurring revenue from Enagas' infrastructure activities.
