Intuit's Fiscal Q3 Performance Driven by Tax Segment Strength, Morgan Stanley Says

Intuit's (INTU) better-than-expected fiscal Q3 results were driven by strong growth in TurboTax Live and Consumer Tax revenue, Morgan Stanley said Friday in a research note.

The company reported non-GAAP earnings of $11.65 per diluted share for the quarter ended April 30, ahead of the Street consensus of $10.93. Revenue rose to $7.75 billion, topping expectations of $7.57 billion. Intuit also raised its fiscal 2025 revenue and EPS guidance.

TurboTax Live revenue jumped 47% year over year, with unit growth of 24%, a sharp acceleration from last year's 17% and 12%, respectively. Consumer Tax revenue grew 11% year over year, beating the Street's 8% estimate, which likely prompted management to raise its fiscal 2025 segment outlook from 7-8% to 10%, the brokerage said.
