Financing Information

As previously disclosed, on June 17, 2024, Illumina entered into a 364-day delayed draw credit agreement that provided for a senior unsecured term loan credit facility in an aggregate principal amount of up to $750 million. The credit facility was drawn in full on June 20, 2024, and the proceeds, together with cash from Illumina's balance sheet, were used to fund cash to the balance sheet of GRAIL in connection with Illumina's divestment of GRAIL. The current borrowing rate under the credit facility is approximately 6.70%.

Distribution Details

The separation was achieved through the distribution of 85.5% of the outstanding shares of GRAIL to holders of Illumina common stock at 12:01 a.m. ET on June 24, 2024 (the "Distribution Date"). In addition to retaining their shares of Illumina common stock, Illumina shareholders received one share of GRAIL common stock for every six shares of Illumina stock held as of close of business on the record date of June 13, 2024. Illumina retained 14.5% of the outstanding shares of GRAIL common stock.

On Tuesday, June 25, 2024, the first trading day following the Distribution Date, GRAIL will begin trading "regular way" on Nasdaq under the ticker symbol "GRAL." There will no longer be two markets in Illumina common stock and Illumina will continue to trade on Nasdaq under the ticker symbol "ILMN."

Fractional shares of GRAIL common stock were not distributed to Illumina shareholders and are instead being aggregated and sold in the open market. The net proceeds will be distributed pro rata, in cash, to Illumina shareholders who would otherwise have received a fractional share of GRAIL common stock.

For U.S. federal income tax purposes, Illumina's U.S. shareholders (other than those subject to special rules) generally should not recognize a gain or loss as a result of the distribution of GRAIL shares, except with respect to cash received in lieu of fractional shares.
