Scope and reporting notes
Current 14,000 figure includes contractors and should be labeled workforce, not employee-only headcount. The presentation gives no explicit measurement date; it was published August 10, 2026.
Dana Off-Highway business acquisition closed January 1, 2026. FY2025 4,000 excludes the acquired business and is historical.
FY2025 Form 10-K separately states approximately 8,000 additional employees, excluding contractors, were acquired effective January 1, 2026. No current consolidated employee-only count was verified; do not automatically treat 14,000 as employees or infer Indiana employment.
Allison Transmission is also the name of a legacy business unit in 2026 reporting; this entry describes the listed corporate group, not just that unit.
Company-wide, Indiana, local and parent figures are shown separately. Reporting dates may be older than the date checked. Unavailable figures remain unverified.
