The Company ended fiscal 2010 with $316.3 million in cash and cash equivalents compared to $159.6 million at the end of fiscal 2009. Inventory at the end of fiscal 2010 totaled $57.5 million compared to $44.1 million at the end of fiscal 2009. The Company ended the quarter with 137 stores in North America and Australia.

Christine Day, lululemon’s CEO, stated: “We ended one of the best years in lululemon’s history with strong Q4 results that extended the consistent sales growth and margin expansion that we enjoyed for each quarter of 2010. The exceptionally strong sell through of our Q4 product line leaves us with short term unmet demand in the first quarter due to a low inventory position. However, the strength of our business model and growing guest demand for our product give us the opportunity to accelerate our store and e-commerce channel growth in 2011 and to establish ourselves as the number one women’s athletic wear brand. While we will see some cost pressures in 2011, we are confident in our ability to maintain our business model through disciplined management, operating efficiencies and leverage on higher sales.”

Updated Outlook

For the first quarter of fiscal 2011, we expect net revenue to be in the range of $175 million to $180 million based on a comparable-store sales percentage increase in the low double digits on a constant-dollar basis. Diluted earnings per share are expected to be in the range of $0.36 to $0.38 for the quarter. This assumes 72.4 million diluted weighted-average shares outstanding and a 36% tax rate.

For fiscal 2011, we expect net revenue to be in the range of $885 million to $900 million and diluted earnings per share are expected to be in the range of $1.90 to $2.00 for the full year. This assumes a tax rate of 36% and 72.6 million diluted weighted-average shares outstanding.

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.
