AI Insider Summary

Some of the stock options Francis Lo exercised in the first half of July 2026 were struck as low as $3.99 a share. Others, exercised the same week, were struck as high as $12.14 — a threefold spread in cost basis across five distinct option tranches. All of it was sold within days at essentially the same price: $22.18 to $22.59. Across three trading sessions — July 1, July 2 and July 15 — Lo exercised roughly 181,000 shares' worth of options across those five strike prices and sold roughly 201,600 shares on the open market, worth a combined $4.5 million. The largest single day was July 15, when 105,762 shares from three tranches (struck at $7.80, $8.46 and $12.14) were exercised and sold the same day at $22.59. Across all 133 transactions in this record, spanning February 2020 through July 2026, Lo has sold 631,386 shares in total and never bought any — a pattern of systematic option exercise and same-day sale rather than a single discretionary decision.

The activity ran across three trading sessions. On July 1, five separate exercises totaling roughly 37,800 shares were sold the same day in two blocks, 42,261 shares at $22.50 and 8,743 shares at $22.18. On July 2, three exercises totaling 37,863 shares were sold as a single 44,838-share block at $22.59. On July 15, the largest session, three exercises — 59,374 shares at a $7.80 strike, 22,711 at $8.46, and 23,677 at $12.14 — totaled exactly 105,762 shares, sold that same day in one block at $22.59.

Adding up the three sessions: roughly 181,000 shares exercised across five different strike prices, and roughly 201,600 shares sold on the open market, worth a combined $4.5 million in proceeds over just two weeks.
