ACS (ISIN ES0167050915) was last at EUR 95 on BME on October 2, 2026, at 5:38 p.m. CEST, up 3.20 percent from EUR 92.05. The immediate catalyst was a new long-term nuclear contract for ACS subsidiary HOCHTIEF in the United Kingdom, announced by ACS on September 30, 2026.

Sellafield adds long-term visibility

HOCHTIEF Infrastructure will support Lot 2 of Sellafield's Project and Asset Care Execution framework. The contract has a value of up to GBP 1.5 billion, equivalent to EUR 1.75 billion in the company release, and can run for 15 years through an initial nine-year term and a six-year extension.

The work covers design, procurement, installation, commissioning, asset care and project management at the United Kingdom's largest nuclear site. For ACS, the significance lies in the service mix: the award adds maintenance and development work to a portfolio that already spans construction, infrastructure and digital assets.

Half-year profit supports the contract story

Benzinga reported that ACS's first-half 2026 attributable net profit reached EUR 510 million, up 13.3 percent year over year, while ordinary net profit increased 30 percent. The company raised its 2026 ordinary net profit growth forecast to 30 percent to 35 percent.

The order book reached EUR 105.856 billion, up 21 percent on a comparable basis, according to Benzinga. Turner, another ACS business, improved its EBITDA margin by 64 basis points to 4.0 percent, making margin delivery a key checkpoint for the next update.

Analyst targets remain above the market

Marketscreener shows an Outperform consensus from 17 analysts, with an average target of EUR 130.32, a high target of EUR 159.00 and a low target of EUR 78.10. The average target lies 37.18 percent above the EUR 95 reference price on October 2, 2026.

The next scheduled checkpoint is November 12, 2026, when ACS plans to publish its nine-month results and hold a Capital Markets Day, as Benzinga reported. That event should put the Sellafield award, Turner margins and the 30 percent to 35 percent earnings outlook into one operational frame.

Stock sits 32.72 percent below yearly high

ACS stock was last at EUR 95 on BME on October 2, 2026, with a session range of EUR 93.20 to EUR 95.60 and volume of 403,456 shares. The 52-week range is EUR 69.35 to EUR 141.20, placing the latest price 32.72 percent below the high.
