What Is an ESOP?
An Employee Stock Ownership Plan (ESOP) is a defined-contribution retirement plan designed to invest primarily in employer stock. Form 5500 filings let readers compare the reported assets of plans tagged as ESOPs for plan year 2024; the plan document, not this ranking, controls an individual's benefits.

How ESOPs Work
The IRS describes an ESOP as a qualified defined-contribution plan that is designed to invest primarily in qualifying employer securities. The plan's governing documents determine how shares are acquired and allocated, when a participant becomes vested, and how distributions work. Those details vary by plan. ESOPs are one of several defined-contribution plan structures alongside 401(k) and profit-sharing plans.
- Read the Summary Plan Description for eligibility, allocation, vesting, and distribution rules.
- Use the annual Form 5500 filing to understand the plan's reported assets and filings, not to infer an individual account balance.
- Ask the plan administrator about the plan document and trust agreement when a benefit question turns on a plan-specific rule.
ESOP Advantages and Risks
Employee ownership can give workers a financial stake in their employer, but it can also concentrate employment income and retirement savings around the same company. The Department of Labor notes that an ESOP's governing documents and the applicable federal rules determine participant rights, including any diversification or distribution options. For a broader view of how plan assets compare across types, see the national retirement plan statistics. This page is explanatory, not individual retirement, tax, or legal advice.

ESOP concentration patterns
ESOPs cluster in industries where private ownership transitions are common, construction, professional services, and manufacturing together account for over half of all ESOP filings. Geographically, California leads by count but not by assets: states like Texas and Ohio hold more ESOP wealth in fewer plans, reflecting larger average plan sizes in those markets. For how these states compare across all plan types, see the top states by retirement plan participants.
What the Form 5500 data can show
The ranking above uses the plan-level records in the Department of Labor's public Form 5500 dataset. It can compare reported end-of-year assets across the plans that are tagged as ESOPs in the selected plan year and link each row to its record on this site. It does not establish how many shares a particular worker holds, whether a worker is vested, or when a distribution is due.
