Adient US LLC Savings and Investment (401(k)) Plan is an ESOP with a 401(k) feature sponsored by Adient US LLC of Plymouth, Michigan. For the plan year ending 31 Dec 2025 it reported 7,916 participants, 5,551 of them active, and net assets of $1.05B.
Net assets came to $112,322 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 $62,303 median for defined contribution plans in manufacturing. 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 $24.9M during the year, or $4,482 per active participant against a same-size median of $2,424; participants contributed $33.6M and $2.1M arrived as rollovers and other contributions. Benefits paid out totalled $107M.
Schedule C lists 4 service provider organisations paid $5,000 or more, with reported compensation of $866K: $109 per participant, well above the same-size median of $53.38. Administrative expenses charged to the plan were $866K. 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 $696M in 2016 to $1.05B in 2025 (up 51%), and participants from 8,081 to 7,916 (down 2%).
The independent accountant's opinion on the financial statements was unmodified (unqualified).

Questions and answers
How big is Adient US LLC Savings and Investment (401(k)) Plan?
7,916 participants at the end of the plan year ending 31 Dec 2025, of whom 5,551 were active employees, with net assets of $1,053,491,212. 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 Adient US LLC contribute per participant?
The filing reports $24,880,804 in employer contributions for the year, which is $4,482 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 $866,314 in compensation to service provider organisations, $109 per participant or 0.08% 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 $866,314. 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 Adient US LLC. Recordkeeping or administration: Fidelity Invest. Inst. Opr. Co.. Investment advisory or management: Financial Engines, Aon Investments USA Inc. and Schwartz & Co.. The financial statements were audited by BDO USA, P.C.. 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 28 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.
