Context

What This Ranking Tells Us

This list ranks standalone ESOPs: Form 5500 filings that carry a DOL ESOP plan-characteristic code (2O non-leveraged, 2P leveraged, or 2Q S-corporation ESOP) and do not also operate a 401(k) salary-deferral feature. That frame matters in both directions. It excludes big-corporation 401(k) plans that merely hold an ESOP component (Walmart, Target, and many other KSOPs appear in the 401(k) ranking instead), and it cannot capture every "employee-owned company" - worker cooperatives, direct-ownership trusts, and firms with partial employee ownership do not necessarily file an ESOP-coded Form 5500. Within that filing-derived frame, the leaders are familiar names in employee ownership: Publix Super Markets, the largest ESOP in the country, followed by Wawa, U-Haul, and WinCo. Unlike survey-based lists, every row here traces to a specific public filing with a stated plan year.

Methodology

How to Read the Largest ESOPs by Participants (Form 5500 Filings) Ranking

This page ranks 50 esop records by participants, from Publix Super Markets, Inc. Employee Stock Ownership Plan & Trust at the top (149,213) through The Sundt Companies Employee Stock Ownership Plan at #50 (3,220). The underlying dataset is drawn from the Department of Labor, Form 5500 Annual Return/Report (ESOP plan-characteristic codes 2O/2P/2Q) for the 2024 plan year. Each ranked entry links to a detail page with the full set of Form 5500 fields, plan type, sponsor EIN, state, participants, net assets, net income, and prior-year history where available.

Rankings based on a single metric can be misleading in isolation - "Participants" captures one dimension of a plan's profile and does not measure participant outcomes, fees, investment options, or funding health. Year-to-year movement in this ranking reflects market performance, workforce changes, plan mergers, and filing timing as much as plan quality. This page is informational only, summarizing public DOL disclosures for research and educational purposes, and is not retirement, tax, legal, or financial advice. Before relying on any ranking to evaluate an employer's plan or make retirement decisions, verify the underlying filing on EFAST2 and consult a qualified professional.

FAQ

Frequently Asked Questions

What counts as an ESOP in this ranking?

A Form 5500 filing that reports an ESOP plan-characteristic code (2O non-leveraged ESOP, 2P leveraged ESOP, or 2Q S-corporation ESOP) without a section 401(k) feature code. Plans that combine an ESOP component with a 401(k) arrangement (KSOPs, common at large public companies) are classified as 401(k) plans here and appear in the largest 401(k) ranking instead.

Is this the same as a list of the biggest employee-owned companies?

Not exactly. "Employee-owned" is a broader idea than an ESOP filing: it can include worker cooperatives, employee ownership trusts, and companies with partial employee ownership that never file an ESOP-coded Form 5500. Organizations like the NCEO publish survey-based employee-ownership lists; this ranking is narrower but fully reproducible, each entry is a specific DOL filing with a participant count the sponsor reported.

Do participant counts equal current employees?

No. Form 5500 participant counts include active employees plus separated and retired participants who still hold account balances. An ESOP with 20,000 reported participants may have meaningfully fewer current employees.

How Plan Rankings Are Constructed

Ranking retirement plans is more subtle than ranking, say, restaurants or stocks. A "largest" plan is unambiguous when measured by participant count or asset total, both are reported in Form 5500 and audited by an independent accountant once a plan crosses the 100-participant threshold. But a "best" plan is contextual: the right benchmark for a multi-employer pension fund is different from the right benchmark for a single-employer 401(k), and both are different from the benchmark for an ESOP. PlainRetire's ranking pages stick to clearly defined, source-derived metrics, participant counts, plan assets, net contribution, employer contribution as a share of pay, and year-over-year asset growth. Each metric has its own page so readers can decide which framing is relevant for their question.

Each ranking includes the underlying source (Form 5500 schedule and line item), the plan-year vintage, and a footnote when an aggregate excludes plans with incomplete or amended filings. Where a plan has filed multiple amendments, a sometimes-routine but sometimes-meaningful signal, the ranking uses the most recent accepted filing and notes the amendment count on the plan detail page. This approach lets readers see who is at the top of a particular ladder without conflating different scales of "size" or "growth."

Methodology and Limitations

Rankings are computed against the most recent annual dataset released by the Department of Labor. New plans, terminations, and significant amendments will not appear until the next annual release, which has roughly a seven-month publication lag from plan year end. Plans that file Form 5500-EZ (single-participant plans) are not included in the public datasets and therefore do not appear in PlainRetire rankings. International plans, government plans, and church plans (which are exempt from Title I of ERISA) are similarly outside the dataset and outside these rankings. When evaluating a ranking, consider the universe being compared: a national ranking of 401(k) sponsors will be dominated by Fortune 500 employers, while a state-level ranking will surface regionally significant plans that don't appear in the national list.

Asset and participant counts are reported by the plan sponsor and certified by an auditor for plans above 100 participants. Smaller plans rely on plan-sponsor attestation. Both are subject to standard data-quality caveats: corrections appear as amended filings in subsequent years, and PlainRetire reflects amendments as soon as DOL releases updated datasets.
