Amentum shares rise as market digests $3.99B credit facility refinancing
AMTM•Amentum Holdings (AMTM) is moving higher as investors digest its newly amended and expanded senior secured credit facilities. The April 24, 2026 refinancing put in place $1.4B Term Loan A, $1.591B Term Loan B, and a $1.0B revolving credit facility, replacing prior facilities.
1. What’s moving the stock
Amentum Holdings shares are higher today as traders and investors focus on the company’s updated financing package disclosed in a recent SEC filing. The company amended its credit agreement on April 24, 2026, establishing a new $1.4 billion five-year senior secured Term Loan A, a $1.591 billion Term Loan B, and a $1.0 billion five-year revolving credit facility, replacing its prior term loan and revolving facilities and fully repaying amounts outstanding under the prior agreement.

2. Why it matters
A refinancing of this size can change the risk profile for a levered government-services contractor by extending maturities, resetting pricing grids, and clarifying covenant headroom. In Amentum’s case, the new structure includes maturities stretching to 2031 for the Term Loan A and revolver, and to 2031 for the Term Loan B, alongside a maximum first-lien net leverage maintenance covenant that applies to the Term Loan A and the revolver (but not the Term Loan B).

3. What investors will watch next
The next questions are whether the refinancing translates into lower all-in borrowing costs as rate margins step with leverage, and whether the new revolving capacity supports working-capital needs and future program wins. Separately, investors are still tracking contract momentum, including Amentum’s recently announced $425 million CAL FIRE aerial firefighting support award, as they assess backlog durability and revenue conversion timing.
