Associated Banc-Corp of Green Bay, Wisconsin sponsors Associated Banc-Corp 401(k) and Employee Stock Ownership Plan, an ESOP with a 401(k) feature. Its Form 5500 for the plan year ending 31 Dec 2025 shows 6,115 participants (3,967 active) and $964M in net assets.
Net assets came to $140,602 per participant in plan year 2024, well above the $64,499 median for defined contribution plans with 5,000 to 24,999 participants and well above the $70,381 median for defined contribution plans in management of companies (holding companies). The figure is an average across everyone in the plan, including former employees with small balances; Form 5500 holds no individual account data.
The employer contributed $17.0M during the year, or $4,295 per active participant against a same-size median of $2,424; participants contributed $30.3M and $5.9M arrived as rollovers and other contributions. Benefits paid out totalled $79.5M.
Schedule C lists 1 service provider organisation paid $5,000 or more, with reported compensation of $296K: $48.48 per participant, below the same-size median of $53.38. Administrative expenses charged to the plan were $296K. 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 $338M in 2009 to $964M in 2025 (up 185%), and participants from 6,343 to 6,115 (down 4%).
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 Associated Banc-Corp 401(k) and Employee Stock Ownership Plan?
6,115 participants at the end of the plan year ending 31 Dec 2025, of whom 3,967 were active employees, with net assets of $963,936,083. Among defined contribution plans that places it in the 5,000 to 24,999 participants band, which held 2,605 plans in plan year 2024.
What does Associated Banc-Corp contribute per participant?
The filing reports $17,038,252 in employer contributions for the year, which is $4,295 per active participant; the median for plans of the same type and size was $2,424 in plan year 2024. Form 5500 reports the total only. It does not state the match formula, and the per-participant figure is an average, not any one person's contribution.
What fees does the plan pay and how do they compare?
Schedule C reports $296,451 in compensation to service provider organisations, $48.48 per participant or 0.03% of net assets. The same-size median among plans reporting any Schedule C compensation was $53.38 per participant. Administrative expenses on Schedule H were $296,452. 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 Associated Banc-Corp. Recordkeeping or administration: Associated Trust Company, N.A.. Investment advisory or management: Associated Trust Company, N.A.. Trustee or custodian: Associated Trust Company, N.A.. The financial statements were audited by Wipfli LLP. 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 20 Jul 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.
