Recent briefings through late September 2026 referenced a series of prior updates covering ISRG's Q2 2026 period. A briefing dated 2026-09-27 noted that earlier recaps from 2026-08-13 and 2026-07-23 had cited broader market conditions during the quarter, including geopolitical turbulence stemming from the US-Iran military conflict.
