Laboratory and R&D Facilities

Our
headquarters is located in Menlo Park, California, where we lease approximately 36,000 square feet of office and laboratory space pursuant to a lease that expires in February 2031. We also lease approximately 90,000 square feet of office and
laboratory space in Union City, California, pursuant to a lease that expires in June 2033. We have an option to extend this lease for an additional five years.

To support our planned growth, we have also entered into a lease for a new facility with 220,000 square feet of office and custom laboratory space located in Austin,
Texas, expected to commence on or before December 31, 2026, and expiring in October 2042, with an option to extend for an additional seven years. We expect the new facility to nearly triple our current testing capacity We also have commercial
leases for patient service centers in various cities, for an aggregate of approximately 8,000 square feet as of June 30, 2025. We expect to enter into additional leases for patient service centers in the ordinary course.

We believe that our current facilities are adequate to meet our current needs and that, should it be needed, suitable additional or alternative space will be available
to accommodate our operations.

Legal Proceedings

From time to time, we
are involved in legal claims, regulatory investigations, inquiries, proceedings and other legal matters arising from the normal course of business and typical for our industry. Although no formal legal proceeding has been instituted, from time to
time, we receive requests from governmental agencies, or third parties working on their behalf, for documents and information related to our products. We do not view any of the legal claims, regulatory investigations, inquiries, proceedings and
other legal matters that we are currently subject to as being material to our business; however, it is difficult to assess the outcome of these matters, and we may not prevail in any current or future proceedings or litigation.

Litigation or any other legal, regulatory or administrative proceedings, regardless of the outcome, can result in substantial cost and diversion of our resources,
including our management’s time and attention, and there can be no assurances that favorable final outcomes will be obtained. For additional information on risks relating to legal proceedings, see the section titled “Risk
