ABM Industries Inc. (ABM) | The Buildout — AI Infrastructure
The Verdict
ABM provides facility maintenance, engineering, and infrastructure services through five segments. It sells into the physical build-out that AI requires — semiconductor fabs, data centers, and power and microgrid infrastructure — mainly through Technical Solutions and the semiconductor-facing part of Manufacturing & Distribution. It is not an AI company and does not report AI-only revenue.

What We Like
- High-tech businesses — semiconductors, microgrids, and data centers — were more than 11% of ABM revenue through the first nine months of FY2026, generated nearly $775 million, grew 26% organically, and carried a double-digit blended operating margin.
- Semiconductor revenue grew 65% organically in the first nine months and more than doubled including almost two quarters of WGNSTAR. WGNSTAR is tracking above its $120 million to $130 million annualized revenue guide with 2 to 3 cross-sells already.
- The data center pipeline is described as a multiple of the prior-year level, with colocation customers as the main near-term target and meaningful conversion expected in fiscal 2027 and 2028.
- Nine-month free cash flow was $199.6 million versus $42.4 million a year earlier, an improvement of over $150 million, and leverage fell to 2.9x, below the 3x target a quarter early.
- M&D grew 18% to $481.0 million in Q3 with an 8.4% margin, or 9.2% excluding WGNSTAR amortization; Education margin was 9.7%, up 70 basis points year over year.
What We’re Watching
- Q4 ATS recovery is the key near-term test: about $15 million of projects were deferred from Q3, almost all expected in Q4 and a little in Q1 FY2027, with double-digit organic growth guided.
- B&I, the largest segment, declined 2.6% in Q3; management expects a return to organic growth around mid-FY2027 as it laps the large UK client exit, with about $70 million of annual revenue impact.
- Aviation margin fell to 5.6% from 6.8% as airline clients seek cost relief from elevated fuel costs; management declined to quantify the concession impact and said pressure is stabilizing.
- Customer concentration is disclosed but unresolved: the FY2025 10-K shows one client at about 32% of a segment's revenue, two clients at about 27%, and one client at about 30%, with segments and counterparties unnamed.
The thesis is strengthening on mix and cash generation but not yet proven on durability. The high-tech bucket is now more than 11% of revenue, growing 26% organically at double-digit margins, while free cash flow and leverage improved ahead of plan. The open question is whether Q4 ATS conversion and mid-FY2027 B&I recovery validate management's timing claims, or whether project timing remains a recurring constraint.
Earnings
ABM reported record FY2026 Q3 revenue of $2.32 billion, up 4.2% year over year, with 2.1% organic growth and 2.1% from acquisitions, primarily WGNSTAR. Gross margin was 12.3%. Adjusted EPS rose 27% to $1.04, and free cash flow was $128.4 million.
| Metric | Q3 FY2026 | Q2 FY2026 | Q3 FY2025 | YoY |
|---|---|---|---|---|
| Revenue | $2.3B | $2.3B | $2.2B | +4.2% |
| Gross margin | 12.3% | 12.1% | 11.7% | +60bps |
| EBITDA | $122M | $117M | $111M | +10.3% |

| Adjusted EPS | $1.04 | $0.90 | $0.82 | +26.8% |
Revenue grew 4.2% year over year to an all time quarterly record of slightly above $2.3 billion driven by 2.1% organic growth and a 2.1% contribution from acquisitions, primarily WGNSTAR.— David Orr, CFO, 2026-09-08
Management tone: On the Q3 call, management was confident and execution-focused. It quantified the $15 million ATS deferrals and said work was already underway, raised the adjusted EPS midpoint and free cash flow outlook, and noted leverage below 3x a quarter early. It declined to size aviation airline cost-relief concessions and did not revisit the prior Q2 self-insurance de-risking commitment or the M&A pipeline.
Management Guidance
For FY2026, management guided organic revenue growth of 3% to 4% toward the higher end, with WGNSTAR adding about 1 point for total growth at the high end of 4% to 5%. Adjusted EPS is guided to $3.95 to $4.10, segment operating margin to 7.7% to 7.8%, normalized free cash flow to approximately $285 million, reported free cash flow to approximately $210 million, interest expense to approximately $110 million, and a normalized tax rate of 29% to 30%. For Q4, management guided consolidated margin north of 8%, ATS operating margin of 10% to 11%, and double-digit ATS organic growth.
Trajectory
Revenue growth decelerated on the headline from Q2 to Q3 FY2026, largely because B&I declined 2.6% and ATS organic growth slowed to 2% on about $15 million of client deferrals. Gross margin improved to 12.3% from 11.7% a year earlier, and segment operating margin rose to 7.7%, up 40 basis points sequentially. The high-tech bucket grew 26% organically, and nine-month free cash flow rose to $199.6 million from $42.4 million a year earlier.
The Model
The model projects FY+1 revenue of $9,709.0 million and EBITDA of $611 million, a 6.29% margin. For FY+2, it projects revenue of $10,279 million and EBITDA of $675 million, a 6.57% margin. The near-term anchor is Q4 ATS execution and the high-tech mix, while FY+2 depends on data center pipeline conversion in fiscal 2027 and 2028, semiconductor and WGNSTAR cross-sells, and microgrid growth.

What Could Go Right — and Wrong
- Q4 ATS delivers double-digit organic growth at 10% to 11% margin, and the roughly $15 million of deferred projects land in Q4 and Q1 FY2027.
- Data center organic growth accelerates from 8% as the pipeline converts in fiscal 2027 and 2028.
- The high-tech bucket keeps compounding at about 26% organic, lifting the blended margin.
- B&I returns to organic growth around mid-FY2027 as the large UK client exit laps.
- WGNSTAR cross-sells convert into named multi-year fab services contracts.
- Another ATS timing miss, with the deferred work slipping again.
- Aviation margin stays at 5.5% to 5.6% as airline cost-relief concessions persist.
- B&I does not inflect in mid-FY2027, leaving the largest segment in decline.
- High-tech growth slows before the mix shift lifts margin, with semiconductor normalizing, data center conversion slipping, and microgrids staying lumpy.
- Customer concentration: loss or reduction in an unnamed client at about 30% or more of a segment.
Looking Ahead
The next 12 months center on Q4 FY2026 execution and the FY2027 outlook management has said it will share with Q4 results in December. Management has guided Q4 consolidated margin north of 8%, double-digit ATS organic growth, and ATS operating margin of 10% to 11%. It also expects the roughly $15 million of deferred ATS projects to land mostly in Q4, B&I to return to organic growth around mid-FY2027, and data center pipeline conversion in FY2027 and 2028.
- Coming days as of 2026-09-08Army Corps finalization — About $20M microgrid project; execution in calendar 2027.
- Q4 FY2026Q4 results and FY2027 guide — Tests Q4 margin north of 8% and ATS recovery.
- Q4 FY2026Deferred ATS projects land — About $15M mostly expected in Q4, a little in Q1 FY2027.
- Q4 FY2026Self-insurance study — Q4 study after Q2 de-risking commitment was not revisited.
- Mid-FY2027B&I return to organic growth — Depends on lapping the large UK client exit.
- FY2027-FY2028Data center pipeline conversion — Meaningful portion of pipeline expected to convert.

The Company
ABM provides facility maintenance, engineering, and infrastructure solutions. Its history dates back to 1909, and it generates revenue exceeding $8.5 billion. It operates five reportable segments: Business & Industry, Manufacturing & Distribution, Education, Aviation, and Technical Solutions. The AI buildout matters to ABM indirectly: it sells services into semiconductor fabs, data centers, and power and microgrid infrastructure, but it is not an AI company and does not report AI-only revenue.
ABM operates from leased offices and operations sites, not owned plants. The FY2025 10-K profile discloses no owned manufacturing plants or factory capacity expansions; its capacity that gates revenue is labor, supervision, engineering depth, and contracts. It employed more than 100,000 people, according to management on the Q3 call. Its largest leased sites include Sugar Land, Texas at 62,500 square feet and Cumming, Georgia at 57,637 square feet.
Business Segments
Competitive Landscape
ABM competes in a fragmented facility-services and technical-infrastructure market. In core janitorial and facilities work, it faces large commercial real estate services platforms and price competition; management said competitors are pricing at levels ABM is not willing to work at. In technical work, it competes with engineering-and-construction firms and energy-infrastructure specialists. Management believes AI will enhance ABM's capabilities rather than disintermediate its core services.
- Named as a competitor. EMCOR's U.S. Building Services grew 5.6% and commercial site-based services rose about 11%, while ABM's B&I revenue declined 2.6%; EMCOR also made five electrical acquisitions.
- Named as a competitor in microgrid and energy infrastructure. Ameresco grew revenue 14% and said data center behind-the-meter conversion remains slow and complex.
- Named as a competitor. Newmark said it is moving into technical facilities management and infrastructure services.
- Named in filings; not discussed.
- Named as a competitor in power equipment and as a supplier of UPS and thermal equipment.
Supply Chain
ABM sits between equipment suppliers and owners of data centers, fabs, and power infrastructure. It buys generators, batteries, UPS systems, switchgear, and cooling equipment, then provides engineering, integration, and facility services. Hyliion names ABM as a deployment partner.
