What AZZ puts in, and what the plan costs
What AZZ put into the plan, per active participant
$1,533
AZZ Inc. put $1,533 into this plan for each of its 2,495 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.
AZZ put in less per active participant than 75% of plans with 1,000–4,999 participants in industrial and materials manufacturing. The middle plan in that group of 766 reported $2,514. Industrial and materials manufacturing comes from business code 332810, which AZZ 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 AZZ 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 $1,533 above is the Form 5500 figure for plan year 2024, and it counts every employer dollar on one line. AZZ Inc. also files a Form 11-K, which states the match formula for plan year 2024: the card below reads $1,733 a year at a $49,500 salary, and the same filing states employer contributions made outside the match. That second figure is what the formula pays one worker on that salary, and not an amount either filing reports. The two figures measure different things, so neither one is the other one corrected.
What AZZ puts in
$1,733
a year, at a $49,500 salary.
The match paragraph, word for word
“The Company currently makes a matching contribution equal to the first 1% of a participant’s compensation that is deferred to the Plan, plus 50% of the next 5% of compensation deferred to the Plan.”
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 369 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%, 0%, 100%, 100%, 100%, 100%, 100%. The score is the average of those 7 readings.
Vesting, word for word
“Participant contributions to the Plan plus actual earnings or losses thereon are fully vested at all times.”
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
40th percentile
$69.41 per participant in plan-paid administrative cost, cheaper than 60% of plans with 1,000–4,999 participants.
What is AZZ's 401(k) match formula?
AZZ's 401(k) employer match tops out at 3.5% of pay. A tiered formula pays its best rate on the first slice of pay and less on the next, which is how the rate steps down.
| Match formula | 100% (dollar-for-dollar) of the first 1% of pay |
|---|---|
| then | 50% of the next 5% of pay |
| Maximum employer match | 3.5% of compensation |
| Other employer contribution | Discretionary non-elective contribution permitted for participants who completed a year of service, 1,000 hours of service during the year, and were employed on the last day of the year; none made in 2024 or 2023 |
At a $90,000 salary, contributing 6% ($5,400) earns the full employer match of $3,150 for the year.
What the filing says, word for word
“The Company currently makes a matching contribution equal to the first 1% of a participant’s compensation that is deferred to the Plan, plus 50% of the next 5% of compensation deferred to the Plan.”

What is AZZ's 401(k) vesting schedule?
AZZ vests the employer match on a cliff schedule: nothing is yours until two years of service, then 100% at once. Leave a day early and the employer money goes back to the plan, the edge a two-year cliff creates.
| Employer match vesting | Cliff: 100% vested after 2 years of service |
|---|---|
| Your own contributions | Immediate: always 100% yours |
| Accelerated vesting | Participants will vest 100% upon attainment of age 65, or in the event of death or disability while employed by the Company. |
| Other employer contributions | Non-elective contributions and non-safe-harbor matching contributions held in the Plan vest in accordance with a schedule: less than 1 year 0%, 1 year 20%, 2 years 40%, 3 years 60%, 4 years 80%, 5 years 100%. |

Who holds your account
Schedule C of the Form 5500 filed for plan year 2024 reports Principal, filed as “PRINCIPAL LIFE INSURANCE COMPANY”. That is the company paid to keep the account records: what is in an account, what went into it, and usually the site a participant signs in to. The trustee that holds the plan’s assets can be a different company, and this filing does not name it.
5,239 plans on file name Principal as their recordkeeper. Of those, the 5,230 with a computable fee have a median plan-paid cost of $170.05 per participant.
