Questions and answers
How big is Axillon Aerospace Group 401(k) Plan?
1,355 participants at the end of the plan year ending 31 Dec 2024, of whom 1,137 were active employees, with net assets of $105,195,511. 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 Carbon Topco, Inc. contribute per participant?
The filing reports $0 in employer contributions for the year, which is $0 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 $0. 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 Carbon Topco, Inc.. The financial statements were audited by RSM US 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 does not state an accountant's opinion type.
How current is this, and does it show my balance?
This is the Form 5500 for the plan year 31 Dec 2024 to 31 Dec 2024, received by the Department of Labor on 2 Dec 2025. 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.
