About ACS Actividades de Construcción y Servicios

ACS Actividades de Construcción y Servicios is a global infrastructure and engineering group focused on complex construction, concessions and high value added industrial and digital projects.

What are the underlying business or industry changes driving this perspective?

• Explosive demand for digital infrastructure and artificial intelligence capacity, evidenced by multi gigawatt data center development and landmark wins such as Meta Louisiana and CoreWeave Pennsylvania, is turning ACS into a scaled specialist in high tech builds, supporting outsized revenue growth and structurally higher EBITDA.
• Global reindustrialization in semiconductors, batteries, critical minerals and advanced manufacturing, supported by large U.S. and European incentive frameworks, is creating a deep pipeline of complex engineering work where ACS already participates in tenders, positioning future backlog and earnings ahead of current market expectations.
• Long duration investment cycles in transport, energy transition and social infrastructure, including rail, hospitals, airports and HVDC grids in core markets like Germany, the U.S. and Australia, underpin a growing, multi year order book that enhances visibility on sales and supports progressive margin expansion.
• Increasing monetization of equity based and concession style platforms such as Abertis, Iridium and the emerging data center vehicle, combined with disciplined capital recycling and asset sales, is expected to elevate recurring cash flow, reduce net debt intensity and support growth in net profit and dividends.
• Operational leverage from integrating Turner's advanced technology focus, CIMIC and Thiess in Asia Pacific, and Dragados and HOCHTIEF in Europe and North America, together with ongoing efficiency programs, is contributing to margin improvement and earnings growth relative to topline expansion.

Assumptions

This narrative explores a more optimistic perspective on ACS Actividades de Construcción y Servicios compared to the consensus, based on a Fair Value that aligns with the bullish cohort of analysts. How have these above catalysts been quantified?

• The bullish analysts are assuming ACS Actividades de Construcción y Servicios's revenue will grow by 11.5% annually over the next 3 years.
• The bullish analysts assume that profit margins will increase from 1.8% today to 2.1% in 3 years time.
• The bullish analysts expect earnings to reach €1.4 billion (and earnings per share of €5.15) by about December 2028, up from €877.6 million today. However, there is some disagreement amongst the analysts with the more bearish ones expecting earnings as low as €1.2 billion.
• In order for the above numbers to justify the price target of the more bullish analyst cohort, the company would need to trade at a PE ratio of 29.2x on those 2028 earnings, up from 24.7x today. This future PE is greater than the current PE for the GB Construction industry at 18.9x.
• The bullish analysts expect the number of shares outstanding to grow by 1.83% per year for the next 3 years.
• To value all of this in today's terms, we will use a discount rate of 12.1%, as per the Simply Wall St company report.

Risks

What could happen that would invalidate this narrative?

• The group is heavily leaning into AI led digital infrastructure and data centers, with EUR 500 million already deployed in land, energy and fiber for a 2.1 gigawatt development and a broader 11 gigawatt pipeline. Any cyclical slowdown in hyperscale AI spending, changes in technology such as cooling standards or cloud architectures, or regulatory constraints on power and permitting could leave ACS overexposed to a narrower growth pocket and force write downs or lower utilization that would pressure revenue growth and EBITDA margins over the long term.
• Turner and CIMIC are currently delivering outsized growth in sectors such as biopharma, health care and advanced technology against a U.S. nonresidential market that is already described as flat to slightly down. This suggests a degree of overperformance that may prove unsustainable once the current wave of high tech awards normalizes, which could lead to slower order intake, weaker book to bill ratios and lower earnings growth than implied by recent 28.6% sales and 23.9% EBITDA expansion.
• The strategy relies on intensive capital deployment into equity investments, M&A and concessions, with EUR 1.2 billion in net equity investments and M&A and EUR 652 million in shareholder remuneration over 12 months contributing to an increase in net debt to EUR 2.2 billion. Any deterioration in traffic at Abertis, delays in monetizing Iridium or the data center platform, or rising interest rates could erode cash generation and constrain the ability to sustain current dividend and profit growth targets, directly affecting net profit and free cash flow.
• Abertis has a large, levered toll road portfolio with EUR 23.4 billion of net debt and is already facing adverse tax changes in France. While management plans to extend concession lives and add new assets, long term shifts in mobility policies, climate regulation, or political pressure on tolls and concession terms in Europe and Latin America could cap tariff growth and shorten asset duration, reducing EBITDA growth and the EUR 600 million dividend stream that underpins ACS earnings and cash flow visibility.

Valuation

How have all the factors above been brought together to estimate a fair value?

• The assumed bullish price target for ACS Actividades de Construcción y Servicios is €106.24, which represents up to two standard deviations above the consensus price target of €80.53. This valuation is based on what can be assumed as the expectations of ACS Actividades de Construcción y Servicios's future earnings growth, profit margins and other risk factors from analysts on the bullish end of the spectrum.
  
• However, there is a degree of disagreement amongst analysts, with the most bullish reporting a price target of €107.0, and the most bearish reporting a price target of just €53.1.
  
• In order for you to agree with the more bullish analyst cohort, you'd need to believe that by 2028, revenues will be €67.4 billion, earnings will come to €1.4 billion, and it would be trading on a PE ratio of 29.2x, assuming you use a discount rate of 12.1%.
  
• Given the current share price of €84.65, the analyst price target of €106.24 is 20.3% higher.
  
• We always encourage you to reach your own conclusions though. So sense check these analyst numbers against your own assumptions and expectations based on your understanding of the business and what you believe is probable.
