All facilities are senior secured and guaranteed by substantially all tangible and intangible assets of Amentum and its wholly owned material domestic restricted subsidiaries.

Insights

Credit and capital structure analyst

Amentum refinances and extends large secured debt stack with new covenant package.

Amentum replaced its prior credit agreement with a structured package: a $1.400 billion term loan A, a $1.591 billion term loan B, and a $1.000 billion revolving facility. Proceeds repaid the old term loan B and revolver, so this is primarily a refinancing and maturity extension.

The term loan A amortizes more quickly than the term loan B and, together with the revolver, carries a financial maintenance covenant based on a maximum first lien net leverage ratio of 4.50x, stepping to 5.00x for four quarters after certain qualified material acquisitions. The term loan B has no maintenance covenants, which gives flexibility for that tranche but concentrates covenant pressure in the A and revolver.

All facilities are senior secured and guaranteed by substantially all tangible and intangible assets of Amentum and its wholly owned material domestic restricted subsidiaries, which is typical for leveraged corporate structures. Actual impact on interest cost will depend on Amentum’s first lien leverage ratio, which drives the margin ranges disclosed in the agreement.

senior secured term loan A facility financial

"a new five-year senior secured term loan A facility in an aggregate principal amount of $1.400 billion"

A senior secured term loan A facility is a bank-style loan where a company borrows a fixed amount and repays it on a set schedule; the loan is backed by specific company assets (secured) and has first claim over those assets ahead of other creditors (senior). For investors it matters because it creates near-term cash obligations, reduces the asset cushion available to equity or junior creditors, and sets repayment and interest priority—like a mortgage that must be paid down first, which affects the company’s financial risk and reward profile.

senior secured term loan B facility financial

"a new senior secured term loan B facility in an aggregate principal amount of $1.591 billion"

A senior secured term loan B facility is a large, fixed-length bank loan that a company borrows against specific assets as collateral and that ranks high in repayment priority if the company runs into financial trouble. Think of it like a long-term mortgage with a higher interest rate, often held by institutional lenders; investors watch it because its size, interest cost and repayment schedule directly affect a company’s financial risk and ability to pay shareholders.

revolving facility financial

"a new five-year senior secured revolving facility with commitments in an aggregate amount of $1.000 billion"

A revolving facility is a bank loan that works like a company credit card: the borrower can draw funds, repay them, and draw again up to a set limit during the agreement period. It matters to investors because it provides short-term cash flexibility for operations, investments, or emergencies, and the cost or availability of that credit can affect a company’s liquidity, interest expenses, and financial stability.

first lien net leverage ratio financial

"requires compliance with a maximum first lien net leverage ratio of 4.50 to 1.00"

First lien net leverage ratio measures how much of a company’s top-priority secured debt remains after using available cash, compared with the company’s recurring cash earnings. Think of it like the size of a primary mortgage relative to your annual take-home pay after you count money in your savings account. Investors use it to judge credit risk and borrowing capacity: a higher ratio suggests greater default risk, tighter financing terms, or covenant pressure.

financial maintenance covenant financial

"the revolving facility include a financial maintenance covenant that requires compliance with a maximum first lien net leverage ratio"

first-priority security interests financial

"secured by perfected first-priority security interests in substantially all tangible and intangible assets"

Item 1.01. Entry into a Material Definitive Agreement.

Amended Credit Agreement

On April 24, 2026, Amentum Holdings, Inc., a Delaware corporation (“Amentum”), entered into the First

Amendment (the “First Amendment”), dated as of such date, among Amentum, Amentum Services, Inc., a Delaware

corporation (“Amentum Services”), Amentum Technology, Inc., a Tennessee corporation (“Amentum

Technology”), the other loan parties party thereto, the lenders party thereto, the issuing banks party thereto and

JPMorgan Chase Bank, N.A., as administrative agent (the “Administrative Agent”), which amends the Credit

Agreement dated as of September 27, 2024 (the “Existing Credit Agreement” and, as amended by the First

Amendment, the “Credit Agreement”), among Amentum, the borrowing subsidiaries from time to time party thereto,

the lenders from time to time party thereto and the Administrative Agent.

The Credit Agreement provides for, among other things, (a) a new five-year senior secured term loan A facility in an

aggregate principal amount of $1.400 billion, (b) a new senior secured term loan B facility in an aggregate principal

amount of $1.591 billion and (c) a new five-year senior secured revolving facility with commitments in an aggregate

amount of $1.000 billion. The new term loan A facility and the new term loan B facility replaced the existing term

loan B facility under the Existing Credit Agreement, and the new revolving facility replaced the existing revolving

facility under the Existing Credit Agreement. Amentum, Amentum Services and Amentum Technology are co-

borrowers under the term facilities.

Amentum, Amentum Services and Amentum Technology used the proceeds of the term facilities, together with

other cash on hand of Amentum and its subsidiaries, to repay in full all outstanding borrowings and other amounts

under the Existing Credit Agreement and to pay fees and expenses related to the financing. Proceeds of the

revolving facility under the Credit Agreement may be used for general corporate purposes. Any repayments and

prepayments of the term facilities may not be reborrowed; repayments of the revolving facility may be reborrowed

prior to the termination thereof.

The term loan A facility will mature on April 24, 2031 and, prior to its scheduled final maturity, will amortize in

quarterly installments in an aggregate annual amount equal to (a) from September 30, 2026 through June 30, 2028,

2.50% of the original principal amount of the loans borrowed thereunder, (b) from September 30, 2028 through June

30, 2030, 5.00% of the original principal amount of the loans borrowed thereunder and (c) for each fiscal quarter

thereafter, 7.50% of the original principal amount of the loans borrowed thereunder. The term loan B facility will

mature on September 27, 2031 and, prior to its scheduled final maturity, will amortize in equal quarterly installments

in an aggregate annual amount equal to 1.00% of the original principal amount of the loans borrowed thereunder.

The revolving facility will mature on April 24, 2031. Borrowings under the revolving facility are available in U.S.

dollars, Canadian dollars, euro and Sterling. A portion of the revolving facility is available for the issuance of letters

of credit in U.S. dollars, Canadian dollars, euro, Sterling and certain other foreign currencies.

The interest rate per annum applicable to the term loan A facility is, at Amentum’s option, equal to either the

Alternate Base Rate (as defined in the Credit Agreement) plus an interest rate margin of 0.25% to 1.00% or the Term

SOFR (as defined in the Credit Agreement) plus an interest rate margin of 1.25% to 2.00%, in each case, based on

Amentum’s first lien leverage ratio. The interest rate per annum applicable to the term loan B facility is, at

Amentum’s option, equal to either the Alternate Base Rate plus an interest rate margin of 0.75% or the Term SOFR

plus an interest rate margin of 1.75%. The interest rate per annum applicable to the revolving facility under the

Credit Agreement is, at Amentum’s option, equal to either the Alternate Base Rate or Canadian Prime Rate (as

defined in the Credit Agreement) plus an interest rate margin of 0.25% to 1.00% or the Term SOFR, Daily Simple

SOFR (as defined in the Credit Agreement), EURIBOR (as defined in the Credit Agreement), Daily Simple SONIA

(as defined in the Credit Agreement) or Term CORRA (as defined in the Credit Agreement) plus an interest rate

margin of 1.25% to 2.00%, in each case, based on Amentum’s first lien leverage ratio.

The Credit Agreement contains customary prepayment rights and customary mandatory prepayments, as well as

customary affirmative and negative covenants that apply to Amentum and its restricted subsidiaries, including

limitations on indebtedness, liens, restricted payments, restricted debt payments, investments, burdensome

agreements, disposition of assets, transactions with affiliates, conduct of business and fundamental changes. The

term loan B facility does not include any financial maintenance covenants. The term loan A facility and the

revolving facility include a financial maintenance covenant that requires compliance with a maximum first lien net

leverage ratio of 4.50 to 1.00, stepping up to 5.00 to 1.00 for four quarters following the consummation of certain

qualified material acquisitions. A breach of the financial maintenance covenant will only result in a default or event

of default with respect to the term loan B facility if the lenders under the term loan A facility and the revolving

facility have, as a result of such breach, demanded repayment of the obligations under the term loan A facility and

the revolving facility or otherwise accelerated such obligations (and terminated the commitments under the

revolving facility) and such demand or acceleration has not been rescinded.

The Credit Agreement contains customary events of default (with customary qualifications, exceptions, grace

periods and notice provisions), including nonpayment of principal, interest, fees or other amounts, defaults under

other agreements, breach of loan documents, breach of representations and warranties, voluntary and involuntary

bankruptcy or appointment of receiver, unsatisfied judgments and attachments, certain ERISA events, change of

control, invalidity of guaranties, collateral documents and other loan documents, and obligations ceasing to

constitute senior indebtedness for purposes of certain subordinated indebtedness.

The obligations of Amentum, Amentum Services, Amentum Technology and any other borrowing subsidiaries

under the Credit Agreement and certain designated cash management obligations, hedging obligations and ancillary

services obligations, are unconditionally guaranteed on a senior basis (subject to customary exceptions) by, and

secured by perfected first-priority security interests (subject to permitted liens and other customary exceptions) in

substantially all tangible and intangible assets of, Amentum and its wholly owned material domestic restricted

subsidiaries.

Amendment, which is filed as Exhibit 10.1 hereto and is incorporated by reference herein.
