AECOM (ACM) stock intrinsic value fair value estimate & owner earnings analysis

AECOM is a design, engineering, program-management and construction-management consultancy for public infrastructure: transit, highways, water, environmental clean-up, energy and government facilities, with roughly two thirds of its work in the Americas and the rest mainly in the United Kingdom, Australia, the Middle East and Hong Kong. Between 2019 and 2022 it sold its Management Services business and its self-perform construction businesses, so the company today is mostly a professional-services firm paid on cost-plus and time-and-materials terms, with a record $27.8 billion backlog at June 2026. We therefore judge the business from fiscal 2021 onward; the older, larger company described a different business. What the business earns. We measure the cash the owners could take out each year: operating cash flow, minus the swings in working capital, minus stock-based pay, minus the capital spending needed just to keep the business running (AECOM spends well under 1% of revenue on equipment, so almost all of its capital spending is maintenance). On that basis the owners' cash was $3.02 a share in fiscal 2021, $2.83 in 2022, $3.60 in 2023, $5.94 in 2024 and $5.75 in 2025 (year ending September). These figures are lower and more variable than the ones we showed before, because we now strip out working-capital swings; in 2024 and 2025 customers' receivables and advance payments moved against the company and that timing is removed rather than counted as lost earnings. Reported profit was very low in 2023 because of a $279 million write-off of a joint-venture investment and an $86 million impairment; those were non-cash charges against capital spent years earlier, and they are added back here, but repeated losses of that kind belong in the bear case. To value the whole business before its lenders, we add back interest paid (about $167 million in 2025) net of interest earned and remove the share belonging to minority partners in consolidated joint ventures (about $74 million in 2025). That gives a business cash flow of roughly $500 million to $870 million a year over the last five years, with a median near $700 million. We use about $700 million as the normal level, not the higher 2024-2025 figures, because those two years rode a surge in revenue that has since reversed. What changed. In the quarter to June 2026 AECOM took a $337 million pre-tax charge on a single Construction Management project in the Americas, bid in 2019, where poor subcontractor productivity pushed out completion and raised the cost to finish. The quarter showed an operating loss of $76 million, Americas revenue fell 20%, and operating cash flow for the nine months was only $169 million against $625 million a year earlier. Revenue for the nine months was down 6% to $11.2 billion, partly because construction-management starts were delayed and partly the Middle East conflict. The design business itself kept growing (design fee revenue up 4%) and new orders were a record $4.2 billion in the quarter. This is why our values are lower than before: the construction-management segment we had treated as fully de-risked has shown it can still lose a year's worth of profit on one legacy job, and cash generation in fiscal 2026 is weak. Growth. The last full year's owner earnings fell about 3% a share. The base case therefore does not start with growth: year one (fiscal 2026-27) carries about $420 million, reflecting the cash cost of the project overrun and the weak year to date, then returns to roughly $690-710 million and is held flat. We do not credit growth from the 2021 federal infrastructure law, from the record backlog converting at better margins, or from management's margin targets; the infrastructure law's authorizations run out in 2026 and its replacement is not yet enacted, and backlog converts into revenue that has already been running at today's level. We do credit the buyback indirectly only to the extent it has already shrunk the share count (128.6 million diluted shares in the June 2026 quarter, down from 149.7 million in 2021); we do not assume further buybacks. Debt. At June 2026 AECOM owed about $2.72 billion (mainly $1.2 billion of 6% senior notes due 2033 and a $700 million term loan priced around SOFR plus 1.75%, plus finance leases), against $1.01 billion of cash, of which we treat about $600 million as surplus to day-to-day needs. Net debt is therefore about $2.1 billion, or $16.35 a share. The fixed notes cost about 6% and the floating loan about the same, so no adjustment for cost of debt is needed. Leverage is about 1.5 times earnings and there are no large maturities before the 2033 notes. Base case: business cash flow of about $420 million in the first year, about $690 million in the second and about $711 million thereafter, kept flat beyond year ten on the strength of AECOM's long-standing position on recurring public infrastructure programs that need design and oversight whether or not new money is added. The business is worth about $11.6 billion, it owes about $2.1 billion net, leaving about $9.5 billion, or $73.54 a share. Bear case: the shutdown year of 2020, when this company's cash flow fell to less than half its normal level, and the 2009-2011 squeeze on state and municipal budgets are the named precedents. We assume year one at $350 million, a further construction-management loss of the size just seen landing in year three (cash flow $300 million), a public-spending slowdown holding cash flow in the $450-520 million range for years four to six, and recovery only to about $580 million, below today's normal level, because some of the construction-management and Middle East business does not come back. The business is worth about $9.0 billion, owes $2.1 billion, leaving about $6.9 billion or $53.31 a share. Even in this case cash flow covers interest of about $170 million comfortably every year, so the debt does not threaten the equity. Bull case: the delayed construction-management starts arrive, the overrun project is finished without further losses, and the design business keeps its demonstrated 4-5% fee growth for four years before slowing to 3%, taking business cash flow from about $800 million to about $1.02 billion. The business is worth about $15.9 billion, owes $2.1 billion, leaving about $13.8 billion or $107.13 a share. Margin-of-safety price. How sure are we of the earnings level? Moderately. The design business is steady, but in five years since the transformation owners' cash has ranged from $2.83 to $5.94 a share, and the current year will be well below that range; the $700 million normal level sits near the median of what the business has actually done, not its best years. The worst plausible outcome is another legacy fixed-price construction-management job going wrong while public spending pauses, the bear case in essence; the business would survive it, because it owns few hard assets, owes modest debt with nothing due until 2033, and has no single customer that dominates, although it is heavily dependent on government budgets. If we are wrong about the two things most likely to be wrong, the normal earning level (say $600 million, not $700 million) and further project losses, the shares are worth roughly the low $50s. While waiting the company pays a dividend of a little over 1% and has been shrinking its share count. The price assumes a two-to-three-year holding period for the construction-management problem to be worked through and for cash generation to return to its normal level. At $48 the price is below the bear case value, and if the business merely returns to the earning power it has already shown, a gain to the low $70s within two to three years plus the dividend implies about 20% a year. At prices much above $50 that return depends on the base case arriving on time, which the 2026 results make less certain. The margin-of-safety price is $48.
