Construction isn’t exactly a sector known for lightning-fast pivots. It's usually slow, heavy, and burdened by massive debts. But then you look at what happened with Juan Santamaría CEO ACS 2023 and realize the game changed. By the time 2023 rolled around, Santamaría wasn't just a new face in the boardroom; he was the primary architect of a massive cultural and financial overhaul at Actividades de Construcción y Servicios (ACS).
He took the reins from Marcelino Fernández Verdes in 2022, but 2023 was the year the dust actually settled on his vision.
If you've followed the Spanish construction giant at all, you know it was basically a collection of loosely affiliated kingdoms for decades. You had Cimic in Australia, Hochtief in Germany, and Turner in the US. They all did their own thing. Santamaría looked at that and basically said, "No." He spent most of 2023 trying to glue those pieces together into a single, cohesive unit. It’s a move that sounds corporate and boring on paper, but in the world of multi-billion dollar infrastructure, it was a radical shift in how risk is managed.

Why the 2023 Pivot Actually Matters
Most people think of ACS as a company that builds bridges and then walks away. That's the old model. Under the leadership of Juan Santamaría CEO ACS 2023, the focus shifted heavily toward "new generation" infrastructure. We're talking data centers, 5G networks, and massive battery factories.
Why? Because the margins on traditional civil engineering are razor-thin.
Honestly, the risk-reward profile of building a highway in a volatile economy is stressful. Santamaría pushed the company toward the US market—specifically through Turner and Flatiron—because that's where the subsidies are. The Inflation Reduction Act in the United States became a massive tailwind for ACS in 2023. While other European firms were struggling with energy costs at home, Santamaría was doubling down on North American tech infrastructure.
He’s a civil engineer by trade, graduating from the Polytechnic University of Madrid, so he gets the technical side. But his real skill is math—specifically, the balance sheet.
During 2023, he simplified the group's structure. He didn't just want to build things; he wanted to own the process. By increasing the stake in Hochtief and consolidating the Australian operations under the Cimic umbrella, he cut out the middleman. It made the company leaner. It made it faster.
The Turner Power Play
You can't talk about Juan Santamaría CEO ACS 2023 without talking about Turner Construction. It’s the crown jewel of the group. In 2023, Turner was the engine driving a huge portion of the company’s 35 billion euro plus revenue.

Santamaría realized something crucial: the US is going through a massive re-industrialization phase.
He didn't just sit in Madrid. He spent an enormous amount of time ensuring Turner was positioned to win contracts for semi-conductor plants and EV battery facilities. This wasn't just luck. It was a calculated bet that the world was moving away from simple concrete and steel toward high-tech "critical infrastructure."
Beyond the Hard Hats
There's a specific kind of nuance Santamaría brought to the role that his predecessors lacked. He’s younger. He’s more mobile. He doesn't just rely on the "old boys' club" of Spanish business.
He focused heavily on ESG—not just as a buzzword, but as a way to lower the cost of capital. In 2023, if you aren't "green," you aren't getting the cheap loans. He knew that. He pushed for sustainable building practices because they made financial sense, not just because they looked good on a brochure.
One of the most interesting things he did was focus on "early contractor involvement." Instead of just bidding on a finished design and hoping for the best, he pushed ACS companies to get into the room with the client while the project was still a sketch. This reduces the risk of massive cost overruns that usually kill construction margins. It’s a smarter, more collaborative way to work. It’s also much more profitable.
The Challenges Nobody Talks About
It wasn't all a victory lap, though. 2023 was a year of punishing interest rates.
When you're running a company the size of ACS, debt is a constant shadow. Santamaría had to navigate a world where the cost of borrowing was skyrocketing. His strategy? Cash flow. He prioritized projects with high cash conversion. Basically, he wanted the money in the bank as fast as possible to keep the debt-to-EBITDA ratios looking healthy for the ratings agencies like S&P and Moody’s.
There was also the complexity of managing Florentino Pérez.
Pérez is a legend in Spain, not just as the Chairman of ACS but as the President of Real Madrid. He’s a massive personality. For Santamaría to step in as CEO and actually exert influence requires a specific kind of diplomatic skill. He had to honor the legacy of the founder while simultaneously dragging the company into the 21st century. Most people would have folded under that pressure. He didn't.
Breaking Down the 2023 Numbers
If you look at the 2023 financial reports, the geographic distribution of revenue tells the whole story:

Santamaría effectively turned a Spanish company into an American power player that happens to be headquartered in Madrid. It’s a brilliant hedge against the stagnant growth in parts of the Eurozone. He also focused on the "services" side of the business—maintenance and operation. Why build a bridge once when you can get paid to maintain it for thirty years?
What This Means for the Future of Infrastructure
The legacy of Juan Santamaría CEO ACS 2023 is ultimately about de-risking.
He moved away from the "lump sum" contracts that have bankrupted so many construction firms. In these deals, the builder takes all the risk if prices go up. Santamaría shifted the portfolio toward "cost-plus" and "incentive-based" contracts. This means if the price of steel spikes, ACS isn't the one left holding the bag. It’s a subtle change that makes the stock much more attractive to conservative investors.
He also leaned into the digital twin revolution. ACS started using AI and sophisticated modeling to predict where things might go wrong on a job site before a single shovel hit the dirt. In 2023, this moved from a "cool pilot program" to a standard operating procedure across the group’s major subsidiaries.
Real-World Actionable Insights
If you’re looking at the construction or infrastructure space, the "Santamaría Model" offers a few clear lessons:
- Pivot to Tech: Traditional infrastructure is a commodity. Data centers and high-tech manufacturing facilities are where the high-margin growth lives.
- Geographic Hedging: Don't get stuck in one economy. Santamaría’s aggressive push into the US was the safety net ACS needed during European volatility.
- Risk Management over Revenue: It’s better to have a smaller, profitable contract than a massive, risky one. Santamaría prioritized the "bottom line" over "top line" vanity metrics.
- Consolidate Identity: If you own five companies, make sure they talk to each other. The "One ACS" philosophy simplified procurement and shared best practices across continents.
The 2023 era of ACS was defined by a transition from a traditional builder to a global infrastructure manager. It required someone who understood the granular details of engineering but had the stomach for high-level global finance. Santamaría proved he was that person.
To really understand where the industry is going, watch the movements of the ACS North American subsidiaries. That is where the next decade of infrastructure value is being created. The groundwork laid in 2023 wasn't just about finishing projects; it was about redesigning the blueprint of the company itself. Keep an eye on the transition from "construction" to "integrated solutions"—that's the real Santamaría playbook.
Moving forward, focus on companies that mimic this shift toward "critical infrastructure" services rather than just heavy civil works. The era of the simple builder is over; the era of the high-tech infrastructure partner has arrived.
