Signet Jewelers Ltd. reported an increase in total sales for the North America segment, reaching $2.88 billion, up 2.1% from $2.82 billion in the previous year. This growth was attributed mainly to improvements in its three largest brands and an increased penetration of fashion lab-grown diamonds, although partially offset by the underperformance of the James Allen brand. Same store sales in North America rose by 2.2% compared to a 6.6% decrease in the prior year. The average unit retail $(AUR)$ in North America increased by 9.1%, while the number of units sold decreased by 7.0%. Internationally, the segment's total sales increased by 5.0% to $171.9 million, despite a negative exchange translation impact of 1.6%. Overall, Signet's total sales increased by 2.5% to $3.08 billion. Signet's business reflects seasonality, with the fourth quarter typically accounting for 35-40% of annual sales, driven by the holiday season.
