Guardant Health, Inc. 4

Co‑CEO Helmy Eltoukhy transferred and gifted Guardant Health common stock among his revocable trust, The Eltoukhy Foundation, and a donor‑advised fund, with no open‑market trading reported.

On August 26, 2026, Guardant Health Co‑Chief Executive Officer Helmy Eltoukhy reported non‑market transactions involving transfers and gifts of Guardant Health common stock among his related entities and a charitable vehicle. Specifically, 25,000 shares previously held indirectly via the Helmy A. Eltoukhy Revocable Trust were reclassified as held by The Eltoukhy Foundation, reflecting a change in the form of beneficial ownership to a foundation, while a separate 30,000‑share disposition was reported as a gift to a donor‑advised fund at Vanguard. These actions are characterized as charitable gifts and internal reallocations rather than open‑market purchases or sales, and they modestly reduced the trust’s reported indirect stake while increasing shares held by the foundation; no transaction prices or market values were disclosed in the filing, so the dollar amounts must be inferred from prevailing market prices at the time.
