The latest data point for LULU's diluted EPS in Q4'26 stands at 4.97 USD, reflecting a notable increase from the previous quarter's 2.59 USD in Q3'26 and marking one of the higher values in the series, though it represents a year-over-year decline of 18.4%. Over the period from Q1'24 to Q4'26, LULU's diluted EPS exhibits a volatile trend with an overall upward trajectory, starting at 2.28 USD and peaking at 6.09 USD in Q4'25, driven by significant growth in Q4'24 (5.28 USD) and Q4'25. Year-over-year EPS growth was strongest in Q4'24 at 461.7%, but turned negative from Q2'26 onward, with declines accelerating to -18.4% in Q4'26, indicating potential weakening profitability amid quarterly fluctuations typical of the apparel sector. The bar chart visualization highlights these periodic spikes, particularly in Q4 periods, suggesting seasonal strength offset by broader growth challenges.
