This price comes after a previous close at €105.60 on August 20, 2026, highlighting a short-term rebound in the share price.
Recent share performance and trading context
According to a detailed quotation table of ACS shares that covers recent sessions, the stock changed hands at €107.00 on August 21, 2026, with a daily gain of 1.33% and turnover of 41,723 shares, compared with €105.60 on August 20, 2026, when the share price declined by 0.75%. On August 19, 2026, the same source shows ACS closing at €106.40 with a 1.39% drop, demonstrating that the latest move to €107.00 has taken the stock back above that earlier level.
The same market overview indicates that the most recent last official closing price was €105.60, which means the intraday level of €107.00 on August 21, 2026, puts ACS stock 1.40 points above that last close. At these prices, investors are effectively paying a small premium versus the immediate prior sessions while watching the construction group's broader fundamental story.
Revenue base and order book underpin growth
In a news update on its international contracting footprint published on August 20, 2026, ACS highlighted that in 2025 it generated sales of €49.848 billion, supported by large-scale projects in data centers, digital infrastructure, energy, critical minerals, defense, health care, and sustainable transport. The same report points to a record order backlog of €92.858 billion in 2025, reflecting strong demand for ACS services in its core markets and providing substantial visibility for future revenue.
The 2025 revenue figure of €49.848 billion serves as the latest full-year baseline for ACS operations, while the €92.858 billion order book represents almost 1.86 times that annual revenue, indicating that the company has secured work that extends significantly beyond one year's sales. Management commentary cited in the same communication suggests that this order book is being driven particularly by contracts in strategic sectors such as digital infrastructure and energy transition projects.
Looking ahead, the company projects that this growth will be accompanied by improvements in profitability, with an operating profit target of €1.4 billion by the end of 2026, which would represent an increase of 40% compared with 2025 levels. This quantified guidance implies that ACS expects to convert its record backlog into higher-margin revenue and that operating income in 2026 will be materially stronger than in the prior year.
International ranking and external revenue exposure
A feature article on international contractors published on August 20, 2026, reports that ACS once again leads a ranking of the largest international construction companies by external revenue, with international business of $52.861 billion, equivalent to €45.457 billion at current exchange rates. This ranking underscores the company's scale outside its home Spanish market and shows that international activities represent a significant share of its overall revenue base.
The same analysis notes that ACS and its affiliate Hochtief have maintained their leadership position in global contracting, demonstrating the competitiveness of European construction groups in a market landscape where Chinese companies also have a substantial presence. For investors, the figure of $52.861 billion in overseas revenue in 2025 stands out as a key indicator of ACS exposure to international demand cycles and infrastructure spending trends.
Flagship infrastructure and services projects
One of ACS core business pillars is large-scale infrastructure, including transportation, energy, and digital projects. The company engages in designing, building, and operating assets such as highways, rail lines, data centers, and energy facilities, often through concessions or long-term contracts. These projects contribute to the €49.848 billion sales base reported for 2025 and feed into the €92.858 billion backlog that extends into future years.
In addition to heavy civil construction, ACS participates in services businesses including maintenance, industrial services, and facility management, which can provide recurring revenue streams alongside the more cyclical project portfolio. As the international ranking article highlights, many of the largest contracts are located in North America and other overseas markets, where ACS and Hochtief have secured complex engineering and construction mandates.
Representative data center project
A representative example of ACS activities is its involvement in data center construction projects that support the expansion of cloud computing and digital infrastructure. According to the recent corporate update, the company identifies data centers as one of the strategic sectors contributing to both the €49.848 billion of 2025 sales and the €92.858 billion record order book. These projects typically involve high-specification facilities with stringent requirements for reliability and energy efficiency, which can command attractive contract values and margins.
By participating in such digital infrastructure builds, ACS positions itself within a growth area where demand is being driven by cloud service providers, telecom operators, and enterprise customers. This kind of project portfolio complements more traditional transport and energy infrastructure contracts and supports the projected 40% increase in operating profit by the end of 2026, as the company converts its order book into revenue.
ACS stock and investor takeaway
Based on the latest available quotation table for ACS, the stock traded at €107.00 as of August 21, 2026, during the most recent session recorded, representing a gain of 1.33% on volume of 41,723 shares. With a last official closing price of €105.60 and a substantial backlog of €92.858 billion against 2025 sales of €49.848 billion, investors are evaluating ACS stock in the context of both steady recent share-price performance and guidance for operating profit to reach €1.4 billion by the end of 2026, a 40% increase over 2025.
