The sleeper story is Purple AI becoming the real revenue engine with triple-digit bookings growth and 25% attach rates while traditional endpoint business shrinks to 50% of bookings. Everyone will focus on the net new ARR weakness, but the AI transformation is happening faster than the headline metrics suggest. The binding constraint is new customer acquisition, not platform expansion - existing customers are buying more AI and longer contracts, but macro uncertainty is freezing new logo decisions. Tomer's most telling quote: 'Known endpoint solutions represent approximately half of quarterly bookings' - this isn't an endpoint company anymore, it's an AI security company in transition. My view changes if Q2 net new ARR doesn't recover as promised or if Purple AI attach rates plateau below 30%.
