Principal Accounting Officer Mastrocola sells 13,600 shares at $191.96–$192.71 for $2.6M; retains 10.4K shares post-sale

Mastrocola executed 2 separate sales totaling 13,600 shares for $2,612,243.99, reducing her holdings by 56.6% to 10,441 shares. The sales occurred at a blended average price of $192.08, near the company's 52-week high of $201.00, with the current price at $169.80 reflecting a -15.5% decline from peak. Praxis is unprofitable with latest quarterly revenue of $0.00 and a net loss of $-73,934,000.00, though it reported annual revenue growth of +249.5%. The timing of a major insider share reduction by the Principal Accounting Officer at near-peak prices—given the company's cash-burn profile and lack of current revenue generation—warrants scrutiny of the firm's path to profitability and whether this sale reflects confidence constraints at the current valuation.
