What the AI said
Gap: operating margin 5.9%, adjusted diluted EPS $0.42, full-year 'growth in the low double digits', cash $1.4B, inventory $1.9B. Lululemon: gross margin 58.7%, operating margin 20.7%, diluted EPS $1.65.
What was actually true
Gap: operating margin 4.6%, adjusted diluted EPS $0.71, Q4 net sales 'could be down mid-single digits', cash $679M, inventory $3.04B. Lululemon: gross margin 55.9%, operating margin 19%, diluted EPS $2 (adjusted $1.62). CNBC said 5.9% and $0.42 do not appear in Gap's report.
Cost or impact
No dollar cost reported. Microsoft said it expected 'the system may make mistakes during this preview period'.
