Methodology

Reported and consensus figures come from FN2's earnings event records. Market reaction and volume are calculated from daily adjusted bars around the event; abnormal move subtracts the SPY move over the same window.

Analyst target low, average, and high values are derived at request time from each named analyst's latest persisted FMP target. The current-price marker comes from FN2's persisted market snapshot. They are sell-side estimates, not an FN2 valuation or recommendation.

Transcript intelligence is a structured synthesis of the current and prior earnings-call analyses. Missing values stay missing and are never estimated.
