Item 1.01 Entry Into a Material Definitive Agreement.

On August 14, 2017 (the “Second Amendment Effective Date”), Engility Holdings, Inc., a Delaware corporation (the “Company”), and Engility Corporation, a Massachusetts corporation and a wholly owned subsidiary of the Company (the “Borrower”), entered into Amendment No. 2 (the “Second Amendment”) to the Credit Agreement, dated as of August 12, 2016, and amended by Amendment No. 1 thereto, dated as of February 13, 2017, by and among the Borrower, the Company, the several lenders from time to time parties thereto and Morgan Stanley Senior Funding, Inc., as administrative agent and collateral agent (“Morgan Stanley”).

The parties entered into the Second Amendment in order to reduce the interest rate margins applicable to (i) the Borrower’s senior secured term B1 loan facility in the original principal amount of $195 million (“Existing Term B1 Loans”) from 2.25% to 1.75%, in the case of alternate base rate loans, and from 3.25% to 2.75%, in the case of Eurocurrency loans, and (ii) the Borrower’s senior secured term B2 loan facility in the original principal amount of $608 million (“Existing Term B2 Loans”) from 2.75% to 2.25%, in the case of alternate base rate loans, and from 3.75% to 3.25%, in the case of Eurocurrency loans. The Second Amendment was accomplished by (i) the Borrower obtaining new term B1 loan commitments (“Term B1 Loans”) to refinance the Existing Term B1 Loans and Morgan Stanley making additional Term B1 Loans to the Borrower in a principal amount equal to $185 million minus the principal amount of any Existing Term B1 Loans outstanding on the Second Amendment Effective Date that were converted into Term B1 Loans on the Second Amendment Effective Date, and (ii) the Borrower obtaining new term B2 loan commitments (“Term B2 Loans”) to refinance the Existing Term B2 Loans and Morgan Stanley making additional Term B2 Loans to the Borrower in a principal amount equal to $579 million minus the principal amount of any Existing Term B2 Loans outstanding on the Second Amendment Effective Date that were converted into Term B2 Loans on the Amendment Effective Date. The proceeds of the Term B1 Loans and Term B2 Loans, respectively, will be applied to repay in full the Existing Term B1 Loans and Existing Term B2 Loans, respectively, outstanding as of the Second Amendment Effective Date.

The foregoing description of the Second Amendment does not purport to be a complete description of the parties’ rights and obligations under the Second Amendment. The above description is qualified in its entirety by reference to the complete Second Amendment, a copy of which is filed herewith as Exhibit 10.1 and is incorporated herein by reference.
