Q1 2026 EPS of $5.10 beat estimates by +4%, with revenue up 26% YoY to $804M. However, the stock trades at 52x forward P/E and ~89x EV/EBITDA — multiples that price in near-perfection and leave no margin of safety against any deceleration. The Schall Law Firm has launched a governance-related investigation into directors and management (June 9), adding a new risk vector. Insider activity over 90 days shows exclusively Rule-10b5-1 scheduled sales from Maurice Sciammas (EVP Sales) with zero open-market purchases from CEO/CFO/directors — the opposite of conviction buying. Options flow is mildly put-skewed (PC ratio 1.24, net dollar bias -$979K bearish). At ~8% below its all-time high and near-neutral RSI on a stock that has run +63% YTD, the risk/reward for an asymmetric long thesis does not exist at current levels.",

However, valuation has become stretched — forward P/E of ~52x and EV/EBITDA of ~88x leave little error room. The Form 4 cluster that triggered this investigation turned out to be a misleading signal: all recent insider activity is SELLING (CEO Hsing sold ~40k shares on May 18 via Rule 10b5-1; several other insiders selling via pre-planned programs), with ZERO open-market purchases in the past 90 days. A $195M non-cash tax restatement was filed in February 2026 but had no impact on operational metrics or guidance.
