Net assets came to $14,730 per participant in plan year 2024, well below the $48,746 median for defined contribution plans with 250 to 499 participants and well below the $73,951 median for defined contribution plans in professional, scientific and technical services. The figure is an average across everyone in the plan, including former employees with small balances; Form 5500 holds no individual account data.
Schedule C lists 2 service provider organisations paid $5,000 or more, with reported compensation of $60K: $137 per participant, close to the same-size median of $141. Administrative expenses charged to the plan were $60K. Schedule C does not capture every cost: fees netted from fund returns and fees the employer pays directly are outside it.
Across the filings on record, net assets went from $872K in 2015 to $8.3M in 2025 (up 857%), and participants from 139 to 439 (up 216%).
The independent accountant's opinion on the financial statements was unmodified (unqualified), from an audit whose scope was limited under ERISA section 103(a)(3)(C) to exclude investment information certified by a bank or insurer.

Questions and answers
How big is Ampcus, Inc. 401(k) P/s Plan?
439 participants at the end of the plan year ending 31 Dec 2025, of whom 372 were active employees, with net assets of $8,340,825. Among defined contribution plans that places it in the 250 to 499 participants band, which held 17,456 plans in plan year 2024.
What does Ampcus, Inc. contribute per participant?
This filing has no Schedule H financial statement, so employer contributions are not reported here.
What fees does the plan pay and how do they compare?
Schedule C reports $60,296 in compensation to service provider organisations, $137 per participant or 0.72% of net assets. The same-size median among plans reporting any Schedule C compensation was $141 per participant. Administrative expenses on Schedule H were $60,296. Investment costs deducted inside mutual funds and other pooled vehicles are not itemised on Form 5500, so these figures are a floor rather than a full cost.
Who runs the plan?
The sponsor is Ampcus, Inc.. Recordkeeping or administration: ADP, Inc.. Investment advisory or management: ADP Strategic Plan Services. The financial statements were audited by Accountright Inc.. Form 5500 also names the plan administrator's signer and other individuals; this site publishes organisations only.
Was the audit opinion unqualified?
The filing reports an unmodified (unqualified) opinion from a limited-scope audit, in which the accountant did not audit investment information certified by a bank or insurance company. Unmodified (formerly "unqualified") is the standard clean opinion.
How current is this, and does it show my balance?
This is the Form 5500 for the plan year 1 Jan 2025 to 31 Dec 2025, received by the Department of Labor on 19 Aug 2026. Filings are due seven months after the plan year ends, or nine and a half with an extension, so the public record always runs a year or more behind. It contains plan-level totals only: no individual balances, contributions or names of participants exist in the data.
