Item 1.01Entry into a Material Definitive Agreement

On March 31, 2021, Mueller Industries, Inc. (the "Company") entered into a Credit Agreement (the "Credit Agreement") among the Company (as borrower), Bank of America, N.A. ("Bank of America") (as administrative agent), Citizens Bank, N.A., Regions Bank, Truist Bank, and Wells Fargo Bank, National Association (as co-syndication agents), First Horizons Bank, Regions Bank, and U.S. Bank National Association (as co-documentation agents) and other lenders from time to time parties thereto. The Credit Agreement replaces the Company's prior credit agreement among the Company (as borrower), Bank of America (as administrative agent) and certain lenders (including Bank of America) parties thereto, dated as of December 6, 2016.

The Company's total borrowing capacity under the Credit Agreement is $500 million. The Credit Agreement provides for an unsecured $400 million revolving credit facility, which matures March 31, 2026, and a term loan facility of $100 million, which matures March 31, 2022. Funds borrowed under the Credit Agreement may be used by the Company for working capital purposes and other general corporate purposes. In addition, the Credit Agreement provides a sublimit of $50 million for the issuance of letters of credit, a sublimit of $35 million for loans and letters of credit made in certain foreign currencies, and a Swing Line sublimit of $25 million. Outstanding letters of credit and foreign currency loans reduce borrowing availability under the Credit Agreement on a dollar-for-dollar basis.

Loans under the Credit Agreement bear interest, at the Company's option, at a rate per annum equal to (i) the Eurocurrency Rate ("Eurocurrency Rate"), which is determined by the underlying currency of the Credit Extension (LIBOR for those denominated in a LIBOR Quoted Currencies, EURIBOR for those denominated in Euros, CDOR for those denominated in Canadian Dollars) for interest periods (at the Company's option) of one, two, three or six months, or (ii) the Base Rate ("Base Rate") which is equal to the greatest of (a) the overnight federal funds rate plus 0.50 percent, (b) Bank of America's "prime rate" or (c) the Eurocurrency Rate plus 1.00 percent, in each case plus an applicable margin. Applicable margin is based on the Company's consolidated funded indebtedness to capitalization ratio and can range from 112.5 to 162.5 basis points per annum over the Eurocurrency Rate and from 12.5 to 62.5 basis points over the Base Rate. Additionally, a commitment fee is payable quarterly on the average daily unused amount of the commitments and varies from 15.0 to 30.0 basis points per annum based upon the Company's consolidated funded indebtedness to capitalization ratio. Certain fees are also payable in connection with letters of credit, including an annual fee on each letter of credit equal to the applicable margin for loans made at the Eurocurrency Rate times the face amount of such letter of credit.

Borrowings under the Credit Agreement require the Company, among other things, to meet certain minimum financial ratios and to comply with customary affirmative and negative covenants.

The Company's obligations under the Credit Agreement are guaranteed on a joint and several basis by certain of the Company's domestic wholly-owned subsidiaries, including all of its material domestic subsidiaries.

There is no material relationship between the Company and any of the parties to the Credit Agreement other than in respect to the Credit Agreement and other routine commercial banking services.

The description of the Credit Agreement contained herein is qualified in its entirety by reference to the Credit Agreement, a copy of which is attached hereto as Exhibit 10.1 and is incorporated therein by reference.
