What the changes say

  • China’s export ban on sequencing instruments adds a direct threat to Illumina’s sales and operations in China.
  • Tariffs and trade restrictions are newly identified as raising costs, delaying supply, and potentially reducing demand.
  • GRAIL-related risks now emphasize potential shareholder demands, investigations, and litigation after the separation.

What changed since the prior 10-K

New

  • NewRisks Relating to Our Sales of Products and Services, Marketing and Research and Development

    Changes in tariffs, trade restrictions, and customs or export/import regulations have impacted, and we expect will continue to impact, our business by increasing costs and administrative burdens, disrupting cross-border flows, and affecting customer demand

    Tariffs and trade restrictions, including in the U.S. and China, may raise costs and lead times, disrupt shipments, and limit Illumina’s ability to pass costs to customers.

Dropped

  • DroppedRisks Related to Acquisitions, Including the Acquisition of GRAIL

    The Spin-Off could adversely affect the market value of the CVRs

  • DroppedRisks Relating to Government Regulation
