ACS earnings call: growth, data centers and cash

Actividades de Construccion y Servicios SA ((ACSAY)) has held its Q4 earnings call. Read on for the main highlights of the call.

Actividades de Construcción y Servicios SA’s latest earnings call struck an upbeat tone, underpinned by double‑digit revenue growth, strong EBITDA expansion and record backlog. Management acknowledged some balance‑sheet and execution risks, but insisted that powerful data‑center momentum, Turner’s outperformance and solid cash conversion give the group a robust platform for further growth.

Strong top-line growth and rising profitability

Sales climbed 19.7% to EUR 49.8 billion, while ordinary net profit jumped 25.3% to EUR 857 million, or 32.4% on a currency‑adjusted basis. Reported net profit reached EUR 950 million and EBITDA rose 25% to EUR 3.1 billion, with margins improving across business segments and signaling a healthier, more efficient earnings mix.

Cash generation fuels balance-sheet improvement

Net operating cash flow over the last 12 months reached EUR 2.2 billion, EUR 320 million higher after adjusting for factoring. This cash engine allowed ACS to end 2025 with a modest net cash position of EUR 17 million, a swing of EUR 719 million year on year, even after EUR 2.1 billion in investments and payouts to shareholders.

Record backlog and strong order intake

The order backlog hit an all‑time high of EUR 92.9 billion, up 14.6% on a currency‑adjusted basis and giving solid visibility on future revenues. New orders of EUR 62.5 billion, up roughly 26.6–27% FX‑adjusted, drove a healthy book‑to‑bill ratio of 1.3 times, indicating the portfolio is still expanding faster than it is being delivered.

Data centers power digital-infrastructure surge

Digital infrastructure accounted for about 28% of new orders, or around EUR 17.6 billion, representing roughly 130% growth on an FX‑adjusted basis. Global data‑center intake more than doubled to EUR 17 billion in 2025, including major wins such as a 902 MW campus in Wisconsin, a 1 GW project in India, 160 MW in the Netherlands and 58 MW in Malaysia.

Turner delivers standout performance

Turner posted sales of EUR 25.8 billion, up 33.9%, while profit before tax surged over 61% to EUR 921 million and margins widened by about 80 basis points to 3.6%. Net operating cash flow at Turner increased by EUR 523 million to EUR 1.2 billion, lifting net cash to EUR 3.3 billion, with new orders of EUR 33.6 billion and a record EUR 37.7 billion backlog.

Broad-based momentum and margin gains

Engineering and Construction sales rose around 15.1% to more than EUR 10.6 billion, with EBITDA margin expanding 53 basis points to 5.9% and profit before tax up 45.2% FX‑adjusted to EUR 275 million. CIMIC delivered 11.2% sales growth and double‑digit PBT growth FX‑adjusted, while Iridium grew sales 45% and Abertis’ recurring business advanced more than 6%.

Strategic wins in energy, defense and minerals

ACS joined the Amentum/Rolls‑Royce SMR delivery team and secured a nuclear and civil framework contract worth up to EUR 685 million, reinforcing its low‑carbon credentials. Defense backlog reached EUR 3.5 billion, supported by a EUR 1 billion German award, while in critical minerals the group advanced its Vulcan stake and EPCM role, targeting future energy‑transition demand.

Capital deployment and data-center platform build-out

The group invested EUR 1.7 billion in financial assets, including EUR 564 million in data centers, EUR 436 million for Dornan and EUR 200 million for Abertis. It also completed a joint venture with BlackRock GIP covering more than 1.7 GW, with 100 sites already connected to the grid and about 80% of power contracted as commercialization and lease talks progress.

Thin net cash highlights heavy investment

Despite its strong cash generation, ACS ended 2025 with only EUR 17 million of net cash, underscoring the intensity of its capital deployment. Management framed this as a deliberate choice to fund high‑conviction growth projects and sustain shareholder returns, rather than evidence of balance‑sheet weakness, but it does limit short‑term financial buffer.

Abertis’ leverage remains a key concern

Abertis continued to perform solidly at an operational level but was hurt by non‑operating items and carries net debt of EUR 22.7 billion. Management stressed that future dividend capacity hinges on ongoing renegotiations and planned transactions aimed at improving funds‑from‑operations‑to‑debt ratios, making this a central risk to watch.

CIMIC faces cash-timing pressures

At CIMIC, cash flow is being squeezed as large legacy transport and civil projects wind down, reducing advance payments, while new high‑tech contracts are not yet fully cash generative. As a result, attributable net profit grew just 1.4% FX‑adjusted, confirming that the transition in project mix is creating a temporary drag despite solid operational trends.

Slow progress on asset disposals

Several energy and industrial assets remain classified as held for sale longer than originally planned, leaving capital tied up on the balance sheet. Management framed the delay as intentional, saying it prefers to wait for better market conditions and stronger valuations rather than rush disposals that could crystallize unnecessary value leakage.

Conservative FX assumptions temper guidance

Management built its 2026 outlook on cautious foreign‑exchange assumptions, including a weaker U.S. dollar, which could dampen reported results if the currency holds up. Even so, the group targets ordinary net profit growth of 20–25% to as much as EUR 1.07 billion, noting that FX could provide upside if moves are less adverse than modeled.

Hyperscaler concentration and regional imbalances

The booming data‑center pipeline is heavily dependent on hyperscaler demand, exposing ACS to shifts in investment cycles and procurement strategies. Regional dynamics also vary, with Europe progressing more slowly due to regulatory and power‑grid constraints, making the pace of commercialization and leasing on parts of the platform a key execution swing factor.

Guidance underpinned by robust pipelines

For 2026, ACS is guiding 20–25% growth in ordinary net profit to up to EUR 1.070 billion, while Turner is expected to deliver as much as roughly 30% profit growth, implying EUR 1.3–1.4 billion of PBT. Management is planning capital allocation on a conservative EUR 1.5 billion annual cash‑flow basis, backed by data‑center and defense revenue ambitions through 2030 and tangible leasing milestones targeted this year.

ACS’s earnings call portrayed a company in expansion mode, leveraging data centers, defense and infrastructure to drive growth while staying wary of leverage and FX headwinds. For investors, the story combines powerful order momentum and cash generation with execution and balance‑sheet risks that will need close monitoring, but the risk‑reward profile currently tilts clearly to the upside.
