Signet’s Momentum in Bridal and Fashion Jewelry Segments

Signet marked notable gains in its bridal and fashion jewelry segments during the fourth quarter of fiscal 2025. Bridal jewelry, accounting for nearly half of the company’s merchandise sales, posted a 2% increase in average unit retail (“AUR”), its strongest in the past two years. This improvement highlights the success of strategic pricing and innovative product offerings that continue to resonate with affluent consumers.

Fashion jewelry also delivered strong results, with AUR climbing 8%. The key contributor was a 60% year-over-year spike in lab-grown diamond sales as of March 19. This growth not only elevated the premium mix of offerings but also expanded market share by five percentage points. By appealing to both established tastes and newer preferences, Signet is effectively strengthening customer engagement and sustaining AUR momentum across core categories.

SIG’s Streamlined Structure Boosts Efficiency and Cuts Costs

In pursuit of enhanced operational performance, Signet initiated a company-wide restructuring in the fiscal fourth quarter. Shifting from a traditional banner-focused model to a more brand-led strategy, the company streamlined leadership by 30% and centralized essential functions like merchandising, media planning and repair services.

This structural realignment enabled tighter cost controls, particularly around store labor, contributing to a 4.9% year-over-year decrease in SG&A expenses, which totaled $639.2 million in the fiscal fourth quarter. Although a slight percentage increase due to strategic investments in advertising, management anticipates $50-$60 million in annualized savings from these efforts.

Over the longer term, Signet is targeting at least $100 million in SG&A improvements. These measures are intended to accelerate decision-making, improve operational accountability and drive long-term margin expansion.
