LULULEMON ATHLETICA INC. RAISES GUIDANCE FOR FOURTH QUARTER OF FISCAL 2010

Vancouver, Canada — January 11, 2011 — lululemon athletica inc. [NASDAQ: LULU; TSX: LLL] today announced that the Company is raising its guidance for the fourth quarter of fiscal 2010 ending January 30, 2011.

For the fourth quarter of fiscal 2010, the Company now expects diluted earnings per share to be in the range of $0.55 to $0.57 as compared to its previous guidance range for diluted earnings per share of $0.46 to $0.48. The Company’s improved guidance reflects stronger than anticipated net revenues for the quarter.

The Company now expects net revenue to be in the range of $237 million to $239 million for the fourth quarter of fiscal 2010. This compares to the Company’s previous guidance of net revenue in the range of $210 million to $215 million for the quarter, and compares to net revenue of $161 million for the fourth quarter of fiscal 2009. Comparable-store sales for the fourth quarter of fiscal 2010 are expected to reflect a mid- to upper-twenties percentage increase on a constant-dollar basis. This compares to the Company’s previous guidance of high teens comparable-store sales for the fourth quarter of fiscal 2010.

Christine Day, lululemon’s CEO stated: “We are wrapping up another record year for lululemon, one in which we were able to drive strong earnings growth due to exceptional results across our retail and e-commerce channels. In 2010, we were able to strengthen our brand awareness while making key investments for the future. We will be chasing inventory for the remainder of the fourth quarter and into the spring season, and in the near term will be focused once again on matching supply with demand. For fiscal 2011, our plans remain to open 20-25 stores while making key strategic investments to support our long term growth trajectory.”

The Company has also announced that management will be presenting at the ICR XChange Conference on Wednesday, January 12, 2011 in Dana Point, California. See separate release for webcast information.

The Company is providing this information in light of the significant expected outperformance of its original fourth quarter guidance provided in conjunction with the announcement of the Company’s third quarter results on December 9, 2010. Investors should not expect the Company to provide regular interim quarterly updates of guidance or outlook information in advance of quarterly earnings announcement dates.

Non-GAAP Financial Measure

Constant-dollar net revenue changes, which exclude the impact of changes in foreign exchange rates, is not a United States Generally Accepted Accounting Principle (“GAAP”) performance measure. We provide constant-dollar net revenue changes because we use the measure to understand the underlying growth rate of revenue excluding the impact on a quarter-by-quarter basis of changes in foreign exchange rates, which are not under management’s direct control. We believe that disclosing net revenue changes on a constant-dollar basis is useful to investors because it enables them to better understand the level of growth of our business.
