On January 4, 2023, Illumina, Inc. entered into a credit agreement among the Company, as the borrower, the lenders from time to time party thereto, Bank of America, N.A., as administrative agent, an issuing bank and the swingline lender, and the other issuing banks from time to time party thereto. The Credit Agreement provides for a $750 million senior unsecured five-year revolving credit facility (with a $40 million sublimit for swingline borrowings and a $50 million sublimit for letters of credit) (the “Credit Facility”). Any loans under the Credit Facility will have a variable interest rate based on either the term secured overnight financing rate or the alternate base rate, plus an applicable rate that varies with the Company's debt rating and, in the case of loans bearing interest based on the term secured overnight financing rate, a credit spread adjustment equal to 0.10% per annum.

The Credit Agreement includes an option for the Company to elect to increase the commitments under the Credit Facility or to enter into one or more tranches of term loans in the aggregate principal amount of up to $250 million, subject to the consent of the lenders providing the additional commitments or term loans, as applicable, and certain other conditions. The proceeds of the loans under the Credit Facility may be used to finance the working capital needs, and for general corporate or other lawful purposes, of Illumina and its subsidiaries. The Credit Agreement contains financial and operating covenants.

The financial covenant provides for a maximum total leverage ratio. Operating covenants include, among other things, limitations on (i) the incurrence of indebtedness by the Company's subsidiaries, (ii) liens on assets of the Company and its subsidiaries and (iii) certain fundamental changes and the disposition of assets by the Company and its subsidiaries. The Credit Agreement contains other customary covenants, representations and warranties, and events of default.

The Credit Facility matures, and all amounts outstanding thereunder will become due and payable in full, on January 4, 2028, subject to two one-year extensions at the option of the Company, the consent of the extending lenders and certain other conditions. Amounts borrowed under the Credit Facility may be prepaid, and the commitments under the Credit Facility may be terminated by the Company, at any time without premium or penalty. As of the date of this report, no borrowings were outstanding under the Credit Facility.

The commitments under the Credit Agreement replace, in their entirety, the commitments under the Credit Agreement dated as of March 8, 2021 (as amended, restated, amended and restated, supplemented or otherwise modified from time to time, the “Existing Credit Agreement”), among the Company, as the borrower, the lenders party thereto, Bank of America, N.A., as administrative agent, an issuing bank and the swingline lender, and the other issuing banks party thereto. The Existing Credit Agreement and the commitments thereunder were terminated as of January 4, 2023.
