Maximum employer match, as a share of pay

4%

Huntington Ingalls Industries, Inc. matches 100% (dollar-for-dollar) of the first 2% of pay, then 50% of the next 2% of pay, then 25% of the next 4% of pay, for a maximum employer match of 4% of pay.

Huntington Ingalls filed two Form 11-K reports for plan year 2025, of which one has been read. The other report has not, so this page cannot say what the plan it covers pays.

From the Form 11-K filed June 10, 2026, covering the plan year ended December 31, 2025. Page data last updated July 28, 2026, when the Form 5500 bulk data was last refreshed. Why filings lag

What Huntington Ingalls puts in, and what the plan costs

What Huntington Ingalls put into the plan, per active participant

$4,233

Huntington Ingalls Industries, Inc. put $4,233 into this plan for each of its 36,917 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.

0 · least per person100 · most per person

Huntington Ingalls put in more per active participant than 50% of plans with 5,000+ participants in aerospace and vehicle manufacturing. The middle plan in that group of 69 reported $4,233. Aerospace and vehicle manufacturing comes from business code 336610, which Huntington Ingalls 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 Huntington Ingalls 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 $4,233 above is the Form 5500 figure for plan year 2024, and it counts every employer dollar on one line. Huntington Ingalls Industries, Inc. also files a Form 11-K, which states the match formula for plan year 2025: the card below reads $1,980 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 cover different plan years and measure different things, so neither one is the other one corrected.

What Huntington Ingalls puts in

$1,980

a year, at a $49,500 salary.

The match paragraph, word for word
The Company’s matching contributions are generally as follows: Company Employee Contribution Match First 2% of participant’s eligible compensation 100% Next 2% of participant’s eligible compensation 50% Next 4% of participant’s eligible compensation 25%

What you contribute to collect all of it

Contribute at least 8% of your pay to collect the full match.

That is $3,960 a year at a $49,500 salary, and it scales with your own.

Vesting score

100 out of 100

How fast the employer’s money becomes yours. Higher than 48% 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.

Vesting scheduleImmediate

Share of the employer's money that is the worker's at hire and at each of the first 6 anniversaries: 100%, 100%, 100%, 100%, 100%, 100%, 100%. The score is the average of those 7 readings.

Vesting, word for word
Vesting — Plan participants are immediately vested in their own and employer matching contributions (including any investment earnings thereon). Plan participants are fully vested in their RAC, plus earnings thereon, upon the completion of three years of vesting service.

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.
