Illumina's planned divestment of GRAIL approved by the European Commission

SAN DIEGO, April 12, 2024

While this does not mean the method of divestment has been finalized, the company is pleased to reach an agreement with the EC on specific divestment options as it represents an important milestone in the process. Illumina continues to explore divesting GRAIL through either a trade sale or a capital markets transaction, each of which are contemplated by the plan approved today. In the event of a capital markets transaction, Illumina must capitalize GRAIL with two-and-a-half years of funding, which is estimated at approximately $1 billion based on GRAIL's long-range plan.

Illumina looks forward to working with the EC on approval of final terms consistent with the divestment plan. As previously stated, Illumina has a goal of finalizing those terms by the end of the second quarter of 2024.
