10-QPeriod: Q2 FY2026

Guardant Health, Inc. Quarterly Report for Q2 Ended Jun 30, 2026

Filed July 30, 2026For Securities:GH

Summary

Guardant Health, Inc. reported strong revenue growth of 44% year-over-year for the second quarter of 2026, reaching $335.0 million, and 46% for the first six months, totaling $636.6 million. This growth was primarily driven by a significant increase in test volumes across its oncology and, notably, its screening segment, with Shield screening test volume more than tripling. Despite this robust top-line performance, the company continued to incur substantial net losses, reporting $120.1 million for the quarter and $232.2 million for the first six months. These losses are a result of continued heavy investment in research and development, and a significant increase in sales and marketing expenses, up 59% and 60% for the respective periods, to support commercial expansion and product adoption. The company's balance sheet shows a healthy cash position of $1.2 billion as of June 30, 2026, providing ample liquidity for continued operations and investment. However, investors should note the ongoing legal proceedings, particularly the intellectual property dispute with TwinStrand Biosciences, which resulted in a significant jury verdict against Guardant Health, with a potential loss estimated between $0 and $250 million. While the company is contesting this verdict and has favorable developments in USPTO reviews of the patents, this remains a material contingent liability.

Frequently Asked Questions

Guardant Health's primary revenue driver is its Oncology segment, which saw a 38% increase year-over-year to $219.1 million in Q2 2026, driven by higher test volumes. The Screening segment, driven by the Shield test, experienced exceptional growth of 257% to $52.9 million in Q2 2026, with test volumes more than tripling, indicating strong market adoption and expansion.

The company continues to operate at a net loss, reporting $120.1 million for Q2 2026 and $232.2 million for the first six months of 2026. While revenue is growing significantly, substantial investments in research and development, along with a considerable increase in sales and marketing expenses, are contributing to these losses. Profitability is not expected in the immediate short term as the company prioritizes growth and market penetration.

A significant financial risk is the ongoing intellectual property dispute with TwinStrand Biosciences, which resulted in a jury verdict against Guardant Health for $83.4 million in damages. The company estimates a potential loss range of $0 to $250 million for this matter, although they are appealing the decision and have seen positive developments in patent office reviews. Additionally, the company's substantial convertible senior notes ($1.5 billion outstanding) represent a significant long-term liability that will need to be managed upon maturity or conversion.

Guardant Health maintains a strong liquidity position with approximately $1.2 billion in cash, cash equivalents, and restricted cash as of June 30, 2026. This ample cash balance, combined with anticipated cash flows from operations, is believed to be sufficient to meet capital requirements for more than 12 months. The company may seek additional capital if needed for expansion, strategic investments, or other opportunities, though this could result in dilution to existing shareholders.
