Corning Incorporated 401(k) match: 4% max

Corning Incorporated Investment Plan · GLW · CIK 24741

Maximum employer match, as a share of pay

4%

Corning Incorporated matches 100% (dollar-for-dollar) of the first 2% of pay, then 50% of the next 4% of pay, for a maximum employer match of 4% of pay.

Corning's Form 11-K filings for plan year 2025 describe two separate 401(k) plans. The terms on this page are read from the Corning Incorporated Investment Plan. They do not all state the same match, so each one is listed below with the group it covers and what it pays.

From the Form 11-K filed June 15, 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 Corning puts in, and what the plan costs

What Corning put into the plan, per active participant

$4,107

Corning Incorporated put $4,107 into this plan for each of its 11,726 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

Corning put in less per active participant than 54% of plans with 5,000+ participants in medical devices and other manufacturing. The middle plan in that group of 81 reported $4,432. Medical devices and other manufacturing comes from business code 339900, which Corning 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.

Matched to this employer by sponsor name, not by an identifier stated in the filing. This record could cover another plan of the same employer.

What this figure cannot separate: how much Corning 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 $4,107 above is the Form 5500 figure for plan year 2024, and it counts every employer dollar on one line. Corning Incorporated 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. 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 Corning puts in

$1,980

a year, at a $49,500 salary.

The match paragraph, word for word
Employees receive matching contributions that equal 100% of the first 2% of eligible pay contributed and 50% of the next 4% of the eligible pay contributed.

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

How fast the employer’s money becomes yours. Higher than 4% 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 scheduleCliff, 3 years

Share of the employer's money that is the worker's at hire and at each of the first 6 anniversaries: 0%, 0%, 0%, 100%, 100%, 100%, 100%. The score is the average of those 7 readings.

Vesting, word for word
Participants are vested immediately in their contributions plus actual earnings thereon. Company contributions to the Plan are fully vested after three years of service. All Company contributions become fully vested upon attainment of Early or Normal Retirement Age, total and permanent disability, or death.

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 is Corning's 401(k) match formula?

Corning's 401(k) employer match tops out at 4% 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.

What is Corning's 401(k) vesting schedule?

Corning vests the employer match on a cliff schedule: nothing is yours until three years of service, then 100% at once. Leave a day early and the employer money goes back to the plan, the edge a three-year cliff creates.

An employee is eligible for participation in the Plan upon reaching the age of 18 and completing one year of eligible service (or if earlier, upon satisfying the special service requirements with respect to employee contributions for certain long-term part-time employees). Notwithstanding the foregoing, an employee who has attained age 18 and is scheduled on a normal basis to work at least 16 hours a week shall be immediately eligible.
Automatic enrollment, word for word
The Plan includes an auto-enrollment provision whereby all newly eligible employees are automatically enrolled in the Plan unless they affirmatively elect not to participate in the Plan or they make an affirmative election to contribute to the Plan. Automatically enrolled participants have their before-tax deferral rate set at 6% of eligible compensation. New employees have 90 days in which to change or opt-out of this provision before deferrals begin. Such auto-enrolled new employee shall have their before-tax contribution automatically increased annually in 1% increments until the employee’s contribution percentage reaches 10% of eligible compensation, provided the employee has not elected to opt-out of the automatic increase feature.
