The Fund gained 11.99% during the quarter, compared with the 10.48% gain for the Russell 3000 Health Care Index and the 15.44% gain for the Russell 3000 Index. Since inception, the Fund appreciated 10.61% on an annualized basis, compared with 10.02% for the Benchmark and 14.83% for the Index. Strong stock selection in pharmaceuticals, biotechnology, health care equipment, and life sciences tools and services supported the Fund’s outperformance, although limited exposure to managed care stocks reduced relative returns.

Baron Health Care Fund stated the following regarding Guardant Health, Inc. (NASDAQ:GH) in its Q2 2026 investor letter:

Guardant Health, Inc. (NASDAQ:GH) is a specialty diagnostics company best known for its blood-based liquid biopsy tests used in cancer therapy selection, monitoring, and screening. Shares increased following strong first-quarter results, with revenue growing 48% year over-year due to continued adoption of the Guardant360 cancer treatment selection test and accelerating uptake of the Shield colorectal cancer blood test. Guardant360 continues to gain share within the rapidly growing liquid biopsy market, with momentum accelerating following FDA approval of the new Guardant360 Liquid CDx assay, which should qualify for Advanced Diagnostic Laboratory Test status and meaningfully expand average selling prices. Meanwhile, Shield has the potential to drive meaningful upside as adoption continues to beat expectations. Notably, the American Cancer Society recently recommended Shield in its updated colorectal cancer screening guidelines, significantly increasing the potential for expanded commercial insurance coverage. Looking ahead, we see Guardant360, Shield, and Reveal (Guardant’s cancer recurrence monitoring test) positioning the company to achieve positive free cash flow over time.”
