Item 1.01. Entry into a Material Definitive Agreement.

SiteOne Landscape Supply, Inc. (the “Company”) announced today that certain of its subsidiaries have entered into the Second Amendment to Amended and Restated Credit Agreement, dated as of May 24, 2017 (the “Second Amendment”), by and among SiteOne Landscape Supply Holding, LLC (“Holding”) and SiteOne Landscape Supply, LLC, as borrowers (collectively, the “Borrowers”), UBS AG, Stamford Branch, as administrative agent and collateral agent, the several banks and other financial institutions party thereto and certain other parties party thereto from time to time, which amends the Amended and Restated Credit Agreement, dated as of April 29, 2016, as amended on November 23, 2016 (the “Term Loan Facility”), by and among the Borrowers, UBS AG, Stamford Branch, as administrative agent and collateral agent, the several banks and other financial institutions party thereto and certain other parties party thereto from time to time, in order to, among other things, add an additional credit facility under the Term Loan Facility consisting of additional term loans (the “Tranche C Term Loans”) in an aggregate principal amount of $299,493,729.43. Proceeds of the Tranche C Term Loans were used to repay in full the term loans outstanding under the Term Loan Facility immediately prior to effectiveness of the Second Amendment (the “Existing Term Loans”) and pay fees and expenses in connection with the Second Amendment.

The Existing Term Loans bore interest, at Holding’s option, at either (i) an adjusted LIBOR rate plus an applicable margin equal to 4.50% or (ii) an alternative base rate plus an applicable margin equal to 3.50%. The Tranche C Term Loans bear interest, at Holding’s option, at either (i) an adjusted LIBOR rate plus an applicable margin ranging from 3.25% to 3.50% or (ii) an alternative base rate plus an applicable margin ranging from 2.25% to 2.50%. Voluntary prepayments of the Tranche C Term Loans are permitted at any time, in minimum principal amounts, without premium or penalty, subject to a 1.00% premium payable in connection with certain repricing transactions within the first six months after the date of the initial funding of the Tranche C Term Loans. Like the Existing Term Loans, the Tranche C Term Loans will mature on April 29, 2022. The other terms of the Tranche C Term Loans are generally the same as the terms applicable to the Existing Term Loans.

The Company also announced today that certain of its subsidiaries have entered into the Omnibus Amendment, dated as of May 24, 2017 (the “Omnibus Amendment”), by and among the Borrowers, UBS AG, Stamford Branch, as administrative agent and collateral agent, the several banks and other financial institutions party thereto and certain other parties party thereto from time to time, which amends, among other things, the Credit Agreement, dated as of December 23, 2013, by and among the Borrowers, UBS AG, Stamford Branch, as administrative agent and collateral agent, the several banks and other financial institutions party thereto and certain other parties party thereto from time to time, in order to, among other things, update certain provisions relating to secured cash management and hedging obligations.
