Shares of Aritzia surged 16.1% to CA$141.52 on October 9 after the Canadian luxury-casual retailer posted second-quarter results that demolished expectations on every metric. Revenue of C$1.17 billion came in ahead of the consensus forecast of C$1.12 billion, while adjusted EBITDA of $246 million crushed the Street's estimate of $198 million.

Earnings per share of C$1.31 (adjusted) beat the consensus of C$1.05 by nearly 25%. The question now: whether this momentum justifies a stock that still trades above 34 times trailing earnings.

  • The U.S. Is Becoming the Bigger Business — and the Bigger Bet. U.S. revenue jumped 60.3% to C$779.4 million, now comprising 66.6% of total sales. That means two-thirds of Aritzia's business now depends on American consumers — a massive geographic shift for a Vancouver-born brand. If U.S. consumer spending softens, the company's top line is far more exposed than it was even a year ago.

  • Record Profitability Despite Tariff Headwinds. The 21% adjusted EBITDA margin was a Q2 record, achieved "in spite of the tariff and de minimis pressure," with management now forecasting 20% for the full year — 100 basis points above its prior long-range target.

SG&A expenses fell 130 basis points as a share of revenue, driven by cost discipline and what the company calls its "smart spending initiative." Shareholders are effectively getting better earnings per dollar of sales even as the company invests heavily in expansion.

  • The Raised Guidance Topped Even the Bulls. Aritzia raised its full-year revenue outlook to C$4.78–C$4.88 billion, up 29–32% from fiscal 2026.

The Q3 revenue forecast of C$1.275–C$1.325 billion exceeded the analyst consensus of C$1.232 billion — signaling management sees no near-term slowdown. For context, just one quarter ago, full-year guidance was C$4.55–C$4.75 billion , meaning the midpoint jumped roughly 5% in three months.

  • Inventory Is Climbing Fast — On Purpose. Inventory ended the quarter at C$715 million, up 36% year over year. Management says the buildup is deliberate, positioning stock ahead of boutique openings and holiday demand. The company plans 12–13 new stores and four to five repositions this fiscal year, mostly in the U.S. But inventory growing roughly in line with revenue leaves little margin for error if demand cools.

An investor day scheduled for October 27 will unveil a new multi-year strategic plan , potentially the next catalyst. For now, Aritzia has earned its rally — the open question is how much of the future is already priced in.
