Westlake Services Holding Company Employee Stock Ownership Plan is an ESOP with a 401(k) feature sponsored by Westlake Services Holding Company of Los Angeles, California. For the plan year ending 31 Dec 2025 it reported 2,174 participants, 1,917 of them active, and net assets of $591M.
Net assets came to $240,888 per participant in plan year 2024, well above the $50,295 median for defined contribution plans with 1,000 to 4,999 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 $4.6M during the year, or $2,401 per active participant against a same-size median of $2,045; participants contributed $10.3M. Benefits paid out totalled $51.1M.
The filing reports no service provider compensation on Schedule C. That is common where fees are paid by the employer or taken from investment returns, neither of which appears there. Administrative expenses charged to the plan were $317K.
Across the filings on record, net assets went from $88.5M in 2011 to $591M in 2025 (up 568%), and participants from 1,296 to 2,174 (up 68%).

Questions and answers
How big is Westlake Services Holding Company Employee Stock Ownership Plan?
2,174 participants at the end of the plan year ending 31 Dec 2025, of whom 1,917 were active employees, with net assets of $591,207,452. Among defined contribution plans that places it in the 1,000 to 4,999 participants band, which held 10,207 plans in plan year 2024.
What does Westlake Services Holding Company contribute per participant?
The filing reports $4,603,244 in employer contributions for the year, which is $2,401 per active participant; the median for plans of the same type and size was $2,045 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 no provider compensation for the year. Administrative expenses on Schedule H were $316,947. 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 Westlake Services Holding Company. The financial statements were audited by LSL, 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. 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.
