Aritzia at 34x: What the Multiple Gap Versus Lululemon Actually Tells You

Aritzia and Lululemon share the same Canadian roots and a similar premium-positioning playbook. The numbers separating them right now would be almost comic if they did not determine portfolio returns.

Aritzia trades at a P/E of roughly 34 times trailing earnings. Lululemon trades at 9. Both are women's premium apparel brands that built their moats through proprietary products, controlled retail experiences, and U.S. expansion. One is in the growth-and-margin-expansion phase. The other is past it.

The 34-versus-9 multiple gap is not the story. The story is what each multiple is buying you and what can go wrong with the assumption baked into the pricier one.

A comparison that does not need a disclaimer

Aritzia grew fiscal 2026 net revenue 35% to CAD 3.7 billion. Lululemon's latest full-year revenue was about USD 11 billion, growing roughly 4%. That is a scale gap of about 3-to-1 in Lululemon's favor, and a growth gap of about 9-to-1 in Aritzia's favor.

The multiple gap sits between those two extremes. Aritzia's P/E is about 3.7 times Lululemon's. A rough PEG calculation puts Aritzia at roughly 0.97 and Lululemon at 2.25. The math suggests that, growth-adjusted, Aritzia is not the expensive one. But PEG is a backward-looking comfort blanket. What investors really need to assess is whether Aritzia can deliver the acceleration that justifies the multiple, not whether past acceleration looks attractive relative to the price.

The growth is not a rounding error

Aritzia's first quarter of fiscal 2027 -- the 13 weeks ended May 31, 2026 -- reported net revenue of CAD 951 million, up 43% from a year earlier. Comparable sales grew 35%. U.S. revenue, already 67% of the total, jumped 55% to CAD 638 million.

For fiscal 2026 as a whole, the company delivered a four-year revenue CAGR of 25% and raised adjusted EBITDA margins to 17.5%, up 260 basis points from the prior year. Net income surged 84% to CAD 382 million.

The margin expansion is where the operating story gets sharper. Gross profit margin reached 50.3% in Q1 fiscal 2027, up 310 basis points from a year earlier and a 410-basis-point expansion in adjusted EBITDA margin to a record 20.1%. These gains came from IMU improvements, lower markdowns, and expense leverage -- even while the company absorbed additional tariffs and the elimination of the de minimis exemption.

For context, Lululemon's gross margin is about 56% and operating margin around 18%. Aritzia is still a smaller company with a leaner footprint, and it is closing the profitability gap from below while adding 12 to 13 new boutiques this fiscal year.

The growth is real. The question is not whether it is happening but whether the market's expectation of its durability is priced at a level that tolerates a miss.

What the P/E of 34 is actually buying

The market is pricing Aritzia for three things: sustained high-teens revenue growth, continued margin expansion into the high-teens on EBITDA, and successful execution on a rapid U.S. boutique rollout.

Management's fiscal 2027 guidance supports each of these assumptions. Revenue is expected at CAD 4.55 to 4.75 billion, representing 23% to 28% growth. Adjusted EBITDA margin is projected at roughly 19.5%, up from 17.5% in fiscal 2026. SG&A as a percentage of revenue is expected to be flat to down 50 basis points.

But a P/E of 34 does not forgive execution risk the way Lululemon's P/E of 9 does. Lululemon's multiple has already discounted growth deceleration, CEO transition, and consumer hesitation. Aritzia's multiple has not discounted anything.

Think of it this way: if Lululemon misses earnings, the stock is already cheap. If Aritzia misses, the multiple compresses because the entire premium rests on the assumption that the growth trajectory holds. A stock priced at 34 times earnings needs its growth to compound for the valuation to stay intact. That is not a flaw -- it is the structure of a growth premium.

The balance sheet is the one factor that does not say A+

Aritzia holds CAD 472 million in cash and carries minimal traditional debt. The balance sheet looks clean until you look at the commitment side. Capital expenditures are projected at CAD 250 million for fiscal 2027, including roughly CAD 210 million in real-estate projects.

The company is funding an aggressive expansion -- 143 boutiques and counting -- with a mix of operating cash flow, share repurchases, and what amounts to heavy real-estate leverage through lease commitments. A CAD 38.5 million joint-venture investment in Q1 fiscal 2027 and over CAD 90 million used in financing activities suggest the company is deploying capital faster than its cash position alone supports.

This is not a red flag in isolation. Retail expansion is capital-intensive and lease-heavy. But it is worth noting that Aritzia's growth premium is being funded against future store cash flows, not against a mountain of existing cash. If new boutique unit economics do not meet plan, the balance sheet flexibility that looks comfortable today becomes a constraint tomorrow.

Insider selling complicates the alignment story

Articles that group Aritzia with "founder-led" stocks point to Brian Hill's position as founder and executive chairman and his remaining 15.8% equity stake. That stake is meaningful. It is also shrinking.

Hill and his family completed a secondary offering of 1.6 million shares in January 2026, raising CAD 209 million -- all proceeds going to the sellers, not the company. Multiple executives have sold shares throughout 2025 and 2026, with no insider purchases recorded in the same window. The selling occurred while the stock rose roughly 30% over a 90-day period.

Insider selling during a strong run is not unusual. Founders diversify, executives exercise options and manage taxes. The point is not to read betrayal into routine portfolio management. The point is to recognize that the "skin in the game" argument for Aritzia has a qualifier: the people with the most skin have been methodically reducing their exposure. That does not change the growth story. It does change the alignment story.

Where the stock lands

Aritzia sits in a specific zone of the factor stack. Growth and profitability grades are top-quartile relative to any retail-apparel peer set. Valuation is expensive on an absolute basis but reasonable relative to its growth rate. Momentum is strong. The balance sheet is adequate but under pressure from expansion spending. Insider alignment is positive but weakening.

This is not a value play. It is a growth-compounding story where the multiple is earned only if the execution holds. The comparison to Lululemon clarifies what the market is doing: it is paying a premium for being on the left side of an S-curve rather than the right side. The Lululemon investor bought the brand years ago and is watching the growth taper. The Aritzia investor is buying the growth but accepting that any sign of the taper arriving early will compress the multiple.

The portfolio role is clear. Aritzia belongs in a growth sleeve where you tolerate volatility in exchange for revenue compounding above 20%. It is not a ballast stock, not a dividend name, and not a place to park a position you need stability from.

What would change the read on this position is a durable slowdown in comparable-sales growth below 20%, a failure of gross margins to continue expanding, or a new-store rollout that disappoints on unit economics. Any one of those would tell you the growth premium is losing its foundation. Until then, the factor stack supports the thesis -- but the premium demands that the thesis stay intact.
