Allison Transmission Holdings, Inc. filed an amended Form 8‑K to add detailed financial information for its acquisition of Dana Incorporated’s off‑highway business. The Dana Business was bought for $2.732 billion, funded with cash on hand and debt financing.
The amendment supplies audited combined financial statements of the Dana Business for 2023 and 2024 and unaudited interim results through September 30, 2025, plus unaudited pro forma combined results for Allison showing the deal’s impact. In 2024, the Dana Business generated $2.696 billion in net sales and $205 million in net income.
The Dana Business also restated its 2023 and 2024 cash flow statements to correct a foreign‑currency translation error that only affected cash flow classifications, not net income, total equity, or the balance sheet. Independent auditors issued an unqualified opinion on the restated financials.
