What AECOM puts in, and what the plan costs
What AECOM put into the plan, per active participant
$2,839
AECOM put $2,839 into this plan for each of its 17,515 active participants in plan year 2024. This is the whole employer side of the plan: matching money, profit sharing, non-elective and safe-harbor contributions, and reallocated forfeitures. The Form 5500 does not separate them, so this is what the employer put in and not the match.
AECOM put in less per active participant than 54% of plans with 5,000+ participants at law, consulting and engineering firms. The middle plan in that group of 168 reported $2,987. Law, consulting and engineering comes from business code 541330, which AECOM entered on its own Form 5500. Sponsors pick that code themselves, so a code that does not describe what the employer does ranks the plan against the wrong companies.
What this figure cannot separate: how much AECOM pays, and how much it puts in
This is dollars, not a rate. A Form 5500 carries no payroll, so the figure reflects both how much the employer puts in and how much the employer pays: two plans running the same formula report different amounts when one pays better. Crossing the peer group with industry holds most of that difference still, and none of it disappears.
This is one plan year, not an average. A true-up, a plan merger or a one-off contribution moves a single year on its own.

The $2,839 above is the Form 5500 figure for plan year 2024, and it counts every employer dollar on one line. AECOM also files a Form 11-K, which states the match formula for plan year 2025: the card below reads $1,485 a year at a $49,500 salary. That second figure is what the formula pays one worker on that salary, and not an amount either filing reports. The two figures cover different plan years and measure different things, so neither one is the other one corrected.
What AECOM puts in
$1,485
a year, at a $49,500 salary.
The match paragraph, word for word
“The participants’ pre-tax and Roth 401(k) contributions made to the Plan are matched 50% by the Company up to 6% of eligible compensation.”
What you contribute to collect all of it
Contribute at least 6% of your pay to collect the full match.
That is $2,970 a year at a $49,500 salary, and it scales with your own.
Vesting score
71.43 out of 100
How fast the employer’s money becomes yours. Higher than 32% of the 253 schedules we have scored.
It measures vesting speed and nothing else. It says nothing about the size of the match, what the plan charges, or the funds inside it.
Share of the employer's money that is the worker's at hire and at each of the first 6 anniversaries: 0%, 33%, 67%, 100%, 100%, 100%, 100%. The score is the average of those 7 readings.
Vesting, word for word
“Vesting — Participants’ contributions and rollovers, and the earnings thereon, are at all times vested in such participants’ accounts. Vesting in the Company contributions and associated earnings is based on years of continuous service. A participant vests in the Company contributions and associated earnings over a three-year period (33% after one year of service, 67% after two years of service, and 100% after three years of service). In addition, participants who are employees become fully vested upon attaining age 65, becoming disabled or deceased while employed at the Company, or upon termination of the Plan.”
The wait before the match starts and the year-end true-up appear above when the filing states them. Neither is part of the score, and a filing that is silent on one of them is not a plan without it.
What the plan costs, against plans of its size
37th percentile
$42.39 per participant in plan-paid administrative cost, cheaper than 63% of plans with 5,000+ participants.
What is AECOM's 401(k) match formula?
AECOM's 401(k) employer match tops out at 3% of pay. The match is deposited once a year. One rate up to one limit is the commonest of the four shapes a match formula takes.
| Match formula | 50% of the first 6% of pay |
|---|---|
| Maximum employer match | 3% of compensation |
| Deposited | Once a year |
| Paid in company stock | Yes |
| Conditions | To receive the annual match, participants must generally be employed on the last day of the Plan year. After-tax contributions are not eligible for the match. The annual match is allocated 50% to the participant's selected investments and 50% to AECOM common stock. Participants covered by a collective bargaining agreement, government contract, or specific project agreement receive the match (if any) described in that agreement. |
At a $60,000 salary, contributing 6% ($3,600) earns the full employer match of $1,800 for the year.
What the filing says, word for word
“The participants’ pre-tax and Roth 401(k) contributions made to the Plan are matched 50% by the Company up to 6% of eligible compensation.”

What is AECOM's 401(k) vesting schedule?
AECOM vests the employer match on a graded schedule: 33% after one year, rising to 100% after three. Each step is money that leaves with you that year, which is how a graded schedule differs from a cliff.
| Employer match vesting | Graded: 33% at 1 yr, 67% at 2 yr, 100% at 3 yr |
|---|---|
| Your own contributions | Immediate: always 100% yours |
| Year of service | Years of continuous service |
| Accelerated vesting | Fully vested upon attaining age 65, becoming disabled or deceased while employed at the Company, or upon termination of the Plan; different vesting requirements may apply under a CBA, government contract, specific project agreement, or corporate transaction |
