Earnings bubble check
Current margins may be above sustainable levels — a P/E based on peak earnings can overstate cheapness.
Disclosure regression check
A previously-disclosed line item is no longer reported. Worth checking the filing for why.
Revenue growth and the path to profitability (margin trend) are the primary reads at this stage.
