The short version

What the latest filing tells us

For the plan year ended Dec 31, 2024, AMTECH SYSTEMS, INC. reported $375,806 in employer contributions across the plan and 149 active participants. That works out to $2,522 per active participant. It is useful context, but it is not the current match formula and it does not show what any one employee received.

Participation proxy58%

Active participants divided by all end-of-year plan participants. This is not the company participation rate because the filing does not report every eligible employee.

Employer money trendUp 5.2%

Change in reported employer contribution per active participant across the filing history shown.

Expense trendDown 71.3%

Change in reported administrative expense per participant. Investment expenses may not be included.

Peer context61/100

A filing comparison among similar-size plans in the same industry when enough peers exist.

Where the public filing stops

Current match, vesting, eligibility, employee fees, and investment choices require a dated plan document. Until we have one, those details stay blank.
