What Lam Research puts in, and what the plan costs
What Lam Research put into the plan, per active participant
$4,188
Lam Research Corp put $4,188 into this plan for each of its 8,132 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.
Lam Research put in less per active participant than 62% of plans with 5,000+ participants in computers and electronics manufacturing. The middle plan in that group of 46 reported $4,837. Computers and electronics manufacturing comes from business code 334410, which Lam Research 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 Lam Research 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 $4,188 above is the Form 5500 figure for plan year 2024, and it counts every employer dollar on one line. Lam Research Corp 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, 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 Lam Research puts in
$1,485
a year, at a $49,500 salary.
The match paragraph, word for word
“The Company may make matching contributions as defined in the Plan. In 2025, the Company matched 50% of each eligible participant’s salary deferral contribution (excluding catch-up contributions and after-tax contributions) up to a maximum of the first 6% of the participant’s eligible compensation, on a per-payroll-period basis. If a participant who was an active employee on the last day of the plan year did not receive the full 50% Company match, the Company provided a year end “true up” contribution to provide such participants with the 50% that they would have received had the timing of their contributions not limited the Company match. The Plan also permits additional discretionary matching and profit sharing contributions. No additional discretionary matching contributions or discretionary profit sharing contributions were made for the year ended December 31, 2025.”
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
100 out of 100
How fast the employer’s money becomes yours. Higher than 48% 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: 100%, 100%, 100%, 100%, 100%, 100%, 100%. The score is the average of those 7 readings.
Vesting, word for word
“Participants are immediately vested in their entire account, including employer matching, additional discretionary matching, and discretionary profit sharing contributions (if any).”
The plan tops the match up after year end, so contributing unevenly through the year does not cost the worker part of it.
The same match paragraph, word for word
“The Company may make matching contributions as defined in the Plan. In 2025, the Company matched 50% of each eligible participant’s salary deferral contribution (excluding catch-up contributions and after-tax contributions) up to a maximum of the first 6% of the participant’s eligible compensation, on a per-payroll-period basis. If a participant who was an active employee on the last day of the plan year did not receive the full 50% Company match, the Company provided a year end “true up” contribution to provide such participants with the 50% that they would have received had the timing of their contributions not limited the Company match. The Plan also permits additional discretionary matching and profit sharing contributions. No additional discretionary matching contributions or discretionary profit sharing contributions were made for the year ended December 31, 2025.”
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
57th percentile
$61.55 per participant in plan-paid administrative cost, more expensive than 57% of plans with 5,000+ participants.
What is Lam Research's 401(k) match formula?
Lam Research's 401(k) employer match tops out at 3% of pay. The match is deposited each payroll and the plan pays an annual true-up. What an annual true-up repays is the arithmetic behind that line: it matters most in a year when contributions land unevenly.
| Match formula | 50% of the first 6% of pay |
|---|---|
| Maximum employer match | 3% of compensation |
| True-upA year-end recalculation that repays match lost to uneven contributions. | Yes, annual true-up |
| Deposited | Each payroll |
| Conditions | If a participant who was an active employee on the last day of the plan year did not receive the full 50% Company match, the Company provided a year end "true up" contribution to provide such participants with the 50% that they would have received had the timing of their contributions not limited the Company match. |
| Other employer contribution | Discretionary matching contributions (permitted, none made for year ended December 31, 2025) |
| Other employer contribution | Discretionary profit sharing contributions (permitted, none made for year ended December 31, 2025) |
At a $60,000 salary, contributing 6% ($3,600) earns the full employer match of $1,800 for the year.

What is Lam Research's 401(k) vesting schedule?
Lam Research vests the employer match immediately: 100% is yours as soon as it is paid in. Nothing is forfeited when you leave, which is not true of the two schedules that vest over time.
| Employer match vesting | Immediate: employer match is 100% vested when contributed |
|---|---|
| Your own contributions | Immediate: always 100% yours |
| Other employer contributions | Immediately vested, same as employer match (additional discretionary matching and discretionary profit sharing contributions, if any). |
