BillionToOne, Inc.

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 Factors—Risks Related to Our Business and Strategy—We have been, and in the future may be, involved in legal proceedings, regulatory investigations and inquiries and other legal matters, which may have an adverse effect on our business, financial condition, results of operations and prospects.”
