Credit Facility

On December 9, 2021, we, along with IDEXX Distribution, Inc., IDEXX Operations, Inc., OPTI Medical Systems, Inc., IDEXX Laboratories Canada Corporation, IDEXX B.V., IDEXX Laboratories B.V., and IDEXX Laboratories GmbH, our wholly-owned subsidiaries (whether directly or indirectly held) (collectively, the “Borrowers”), entered into a fourth amended and restated credit agreement (the “Credit Agreement”) relating to a five year unsecured revolving credit facility in the principal amount of $1 billion, among the Borrowers, the lenders party thereto, JPMorgan Chase Bank, N.A., as administrative agent, JPMorgan Chase Bank, N.A., Toronto Branch, as Toronto agent, and the other parties thereto.

The Credit Agreement amends and restates that certain third amended and restated credit agreement, dated as of April 14, 2020, (which provided for a $1 billion three-year unsecured revolving credit facility) to extend the maturity to December 9, 2026 with aggregate commitments available for borrowing by the Borrowers of $1 billion with the option to increase the aggregate commitments by $250 million, for an aggregate maximum of up to $1.25 billion, subject to the Borrowers obtaining commitments from existing or new lenders and satisfying other conditions specified in the Credit Agreement.

Under our Credit Facility prior to the December 9, 2021 amendment, the applicable interest rates on borrowings are based on the prevailing LIBOR, Canadian Dollar Rate, or EURIBOR, but not less than 1.0%, plus a credit spread ranging from 1.375% to 2.00%, based on our gross leverage ratio. The Credit Facility also allowed for borrowings based on the prevailing Prime rate, but not less than 2.00%, plus a credit spread from 0.375% to 1.00%. Under the Credit Facility, we also pay quarterly commitment fees ranging from 0.2% to 0.375%, based on our leverage ratio, on any unused commitment. Under our current amended Credit Facility, the applicable interest rates on borrowings are based on the prevailing LIBOR, Canadian Dollar Rate, or EURIBOR, but not less than 0.0%, plus a credit spread ranging from 0.875% to 1.375%, depending on our gross leverage ratio. The Credit Facility also allowed for borrowings based on the prevailing Prime rate, but not less than 1.00%, plus a credit spread from 0.0% to 0.375%. Under the current Credit Facility, we also pay quarterly commitment fees ranging from 0.075% to 0.25%, based on our leverage ratio, on any unused commitment. Our Credit Facility includes a provision for the determination of one or more benchmark replacement rates (including SOFR) as a successor to the LIBOR rate.

At December 31, 2021, we had $73.5 million outstanding borrowings under our Credit Facility with a weighted average effective interest rate of 1.1%. Our weighted average borrowing rate for the year ended December 31, 2021, was 2.7%, which reflected borrowings under our prior Credit Facility. At December 31, 2020, we had no outstanding borrowings under our Credit Facility. The funds available under the Credit Facility reflect a further reduction due to the issuance of letters of credit, which were issued in connection with our workers’ compensation policy, for $1.4 million in the year ended December 31, 2021 and 2020.

Although the Credit Facility does not mature until December 9, 2026, all individual borrowings under the terms of the Credit Facility with an interest rate based on the prevailing LIBOR, Canadian Dollar Rate, or EURIBOR (as selected by the Borrower) have a stated term between 1 and 180 days. At the end of each term, the obligation is either repaid or rolled over into a new borrowing, or replaced by a borrowing based on a specific benchmark rate (where interest is then paid monthly). The Credit Facility contains a subjective material adverse event notification clause, which allows the debt holders to call the loans under the Credit Facility if we fail to provide prompt written notice to the syndicate of such an event. Based on the stated term and the existence of the subjective material adverse event clause, this Credit Facility is reflected in the current liabilities section of our consolidated balance sheets.

The obligations under the Credit Facility may be accelerated upon the occurrence of an event of default under the Credit Facility, which includes customary events of default including payment defaults, defaults in the performance of the affirmative, negative and financial covenants, the inaccuracy of representations or warranties, bankruptcy and insolvency

related defaults, defaults relating to judgments, certain events related to employee pension benefit plans under the Employee Retirement Income Security Act of 1974, the failure to pay specified indebtedness, cross-acceleration to specified indebtedness, and a change of control default. The Credit Facility contains affirmative, negative, and financial covenants customary for financings of this type. The negative covenants include restrictions on liens, indebtedness of subsidiaries of the Company, fundamental changes, investments, transactions with affiliates, and certain restrictive agreements. The sole financial covenant is a consolidated leverage ratio test that requires our ratio of debt to earnings before interest, taxes, depreciation, amortization, and share-based compensation defined as the consolidated leverage ratio under the terms of the Credit Facility, not to exceed 3.5-to-1. At December 31, 2021, we were in compliance with the covenants of the Credit Facility.

On April 10, 2020, we amended the NY Life 2013 Note Agreement and the NY Life 2014 Note Agreement by entering into two Amendments to Note Purchase Agreement with New York Life Insurance Company and the other parties thereto, which modified several defined terms, schedules and covenant baskets in the NY Life 2013 Agreement and the NY Life 2014 Note Agreement to create additional operating flexibility, and in particular to align such provisions with similar modifications we made substantially concurrently in our other debt facilities.

Prudential 2015 Amended Agreement, Including Amendments

In July 2014, we issued and sold through a private placement an aggregate principal amount of $125 million of unsecured senior notes consisting of $50 million of 3.32% Series A Senior Notes due July 21, 2021 (the “2021 Series A Notes”) and $75 million of 3.76% Series B Senior Notes due July 21, 2024 (the “2024 Series B Notes”) under a Note Purchase and Private Shelf Agreement among the Company, Prudential Investment Management, Inc.

We refer to the Original Prudential 2015 Agreement, as amended by the Prudential First Amendment and the Prudential Second Amendment, as the "Prudential 2015 Amended Agreement."

We entered into a Multicurrency Note Purchase and Private Shelf Agreement, dated as of December 19, 2014 (the "Original MetLife 2014 Note Agreement"), among the Company, Metropolitan Life Insurance Company (“MetLife”) and the accredited institutional purchasers named therein pursuant to which we agreed to issue and sell an aggregate principal amount of $150 million of unsecured senior notes consisting of $75 million of our 3.25% Series A Senior Notes having a seven-year term (the "2022 Series A Notes"), and $75 million of our 3.72% Series B Senior Notes having a twelve-year term ("2027 Series B Notes").

The entire outstanding principal balance of the MetLife 2030 Series D Notes is due and payable on April 2, 2030, and the MetLife 2030 Series D Notes bear interest at the rate of 2.50% per annum. We used the proceeds received from the MetLife 2030 Series D Notes for general corporate purposes.

Senior Note Agreements

The Senior Note Agreements contain affirmative, negative, and financial covenants customary for agreements of this type. The negative covenants include restrictions on liens, indebtedness of our subsidiaries, priority indebtedness, fundamental changes, investments, transactions with affiliates, certain restrictive agreements, and violations of laws and regulations. The sole financial covenant is a consolidated leverage ratio test that requires our ratio of debt to earnings before interest, taxes, depreciation, amortization, and share-based compensation, as defined in the Senior Note Agreements, not to exceed 3.5-to-1. At December 31, 2021, we were in compliance with the covenants of the Senior Note Agreements.

Should we elect to prepay the Senior Notes, such aggregate prepayment will include the applicable make-whole amount(s), as defined within the applicable Senior Note Agreements. Additionally, in the event of a change in control of the Company or upon the disposition of certain assets of the Company the proceeds of which are not reinvested (as defined in the Senior Note Agreements), we may be required to prepay all or a portion of the Senior Notes. The obligations under the Senior Notes may be accelerated upon the occurrence of an event of default under the applicable Senior Note Agreement, each of which includes customary events of default including payment defaults, defaults in the performance of the affirmative, negative and financial covenants, the inaccuracy of representations or warranties, bankruptcy and insolvency related defaults, defaults relating to judgments, certain events related to employee pension benefit plans under the Employee Retirement Income Security Act of 1974, the failure to pay specified indebtedness and cross-acceleration to specified indebtedness. We used the net proceeds from the issuances and sale of the Senior Notes for general corporate purposes.
