QSI

Over the past six months (March-September 2026), Quantum-Si's stock was impacted by several events. The company held earnings calls for Q4 2025, Q1 2026, and Q2 2026, reporting Q2 2026 EPS of -$0.11 (meeting expectations) and revenue of $344,000 (exceeding estimates), despite a 41.8% year-over-year sales decline. QSI participated in two H.C. Wainwright investor conferences. Both CFO Jeffry R. Keyes and CEO Jeffrey Hawkins sold shares in September 2026 as part of mandatory 'sell-to-cover' provisions for tax obligations. A significant concern for investors is the delay in the launch of the next-generation Proteus platform, now postponed to Q2 2027. The stock experienced a 7.82% decline over this period, trading at $0.75 as of September 18, 2026, representing a 50.33% drop from the previous year, with a 52-week range between $0.69 and $3.10.
