Insights

Credit & Capital Structure Analyst

Allison lines up mixed-rate debt to fund a targeted acquisition.

ATI priced fixed-rate senior notes at $500 million with a 5.875% coupon due 2033 and arranged a floating-rate incremental term loan of $1,200 million at Term SOFR + 1.75%. This blend balances duration and rate exposure while providing acquisition funding capacity alongside revolver borrowings and cash.

Proceeds are earmarked to finance the purchase of Dana’s off-highway business and related costs. The notes closing is expected on or about November 21, 2025, subject to customary conditions; the term loan is expected to close concurrently with the acquisition.

Key dependencies include successful completion of the private placement, execution of the credit agreement amendment enabling the term loan, and closing of the acquisition. Actual leverage and interest expense will hinge on final sizing and timing; the filing does not quantify pro forma metrics.
