Will Ulta Beauty's FY2025 inventory turnover ratio fall below 3.50x?

The preliminary math strongly favors NO. COGS = $12.4B × (1 - 0.391) = ~$7.55B. Beginning inventory (FY2024 end) = ~$1.99B. Ending inventory = $2.2B. Simple average = $2.09B. Turns = $7.55B / $2.09B = 3.61x — above 3.50x by a meaningful margin. Even with some calculation differences in the 10-K (quarterly average inventory is often slightly different from simple two-point average), the margin of safety is ~0.11x above the threshold, which would require significant methodology differences to reverse. Management commentary was positive on 'inventory productivity' and shrink improvement. The 10.8% inventory growth is above sales growth (9.7%), but the gap is much smaller than FY2024's 13% inventory growth vs 0.8% sales growth. The trajectory has improved. However, I can't be 100% certain because: (1) the 10-K may use a different average inventory methodology, (2) Space NK inventory could be allocated differently across quarters, and (3) COGS includes items beyond inventory (store costs, distribution). Some residual uncertainty remains.

The calculation is fairly straightforward for a retail company. COGS / average inventory is the standard formula. My estimate: ~$7.55B / ~$2.09B = ~3.61x. The prior prediction of 53% was made before having FY2025 actual financials — it was essentially a coin flip based on the FY2024 trajectory and Space NK unknowns. Now we have the actual numbers and the math clearly points above 3.50x. Key nuance: Ulta's COGS in the 10-K may be slightly different from the simple gross margin calculation because COGS for retailers can include various cost items. Also, the 10-K typically reports a more precise average inventory figure. But the 11 bps margin above 3.50x is substantial enough that methodology differences are unlikely to flip the result. Management's emphasis on inventory productivity suggests they are tracking this metric internally and managing toward it.

I want to be more cautious about the calculation precision. A few factors could push turns below 3.50x: (1) If the 10-K uses quarterly average inventory rather than simple beginning/ending average, Space NK's mid-year acquisition could make the quarterly average higher (because Space NK inventory was on the books for Q2-Q4 but not Q1). This would increase average inventory and lower turns. (2) The $2.2B ending inventory includes Space NK (86 stores of UK inventory), and if Space NK inventory was added mid-year, the quarterly average could be ~$2.15-2.20B rather than $2.09B. At $2.15B average, turns = $7.55B / $2.15B = 3.51x — barely above threshold. At $2.20B, turns = 3.43x — below threshold. So the calculation methodology matters significantly. (3) I don't know exactly when Space NK inventory hit the balance sheet. Given this methodology uncertainty, I assign higher probability than pure two-point average suggests.

Preliminary estimate of 3.61x turns is clearly above 3.50x. The math: $12.4B × 0.609 (COGS ratio) = ~$7.55B COGS. Average inventory (simple: ($1.99B + $2.2B) / 2) = $2.09B. Turns = 3.61x. This is above threshold by a reasonable margin. Management commentary supports: 'inventory productivity' improvements and shrink reduction. Inventory growth (10.8%) tracked much closer to sales growth (9.7%) than in FY2024 (13% vs 0.8%). The decline in turns from FY2024's 3.72x to an estimated 3.61x is concerning as a trend but still above the binary threshold. The main risk is calculation methodology — if 10-K reports different average inventory. But the directional evidence strongly favors NO.

I share Opus Run 3's concern about calculation methodology. Space NK was acquired in July 2025 (Q2 FY2025). If we think about quarterly inventory levels: Q1 ~$1.99B (no Space NK), Q2 ~$2.0-2.1B (Space NK added mid-quarter), Q3 ~$2.1-2.2B, Q4 ~$2.2B. A quarterly average could be: ($1.99 + $2.05 + $2.15 + $2.2) / 4 = ~$2.10B — actually quite close to the simple two-point average. So the methodology concern may be smaller than feared. But there's another issue: Ulta's COGS line in the 10-K may not exactly equal revenue × (1 - gross margin) as presented in the press release due to rounding and line item classifications. I'll estimate 28% to account for these unknowns, though I think the most likely outcome is above 3.50x.

The FY2025 data provides a clear signal. Inventory turns estimated at ~3.61x, above the 3.50x threshold. This represents a continued decline from FY2024's 3.72x (3% decline) but a much slower rate than FY2024's 8.8% decline from FY2023. The deceleration in the decline rate, combined with inventory growth tracking closer to sales growth, suggests the inventory efficiency trend is stabilizing. Management emphasis on 'inventory productivity' and shrink improvement adds qualitative support. The 10-K will provide the definitive answer, but the preliminary data strongly favors NO. Residual 20% accounts for calculation methodology differences.

Estimated turns 3.61x — above 3.50x. COGS ~$7.55B, average inventory ~$2.09B. Inventory growth closer to sales growth than FY2024. Management positive on inventory productivity. Prior 53% was pre-data estimate. Clear shift toward NO. Some residual uncertainty from 10-K methodology.

Math clearly favors NO. $7.55B COGS / $2.09B average inventory = 3.61x. Space NK inventory adds some calculation uncertainty for 10-K methodology. But 11 bps above threshold is meaningful margin. Shrink improvement and inventory productivity emphasis support above-3.50 outcome. Prior 53% dramatically too high given actual data.

FY2025 data strongly favors turns above 3.50x. Estimated 3.61x with reasonable methodology. Inventory management improved — growth tracked closer to sales. Shrink improved. Prior uncertainty was about whether Space NK inventory would push turns below threshold; it appears not. 10-K will confirm but preliminary data is clear. 20% residual for methodology surprises.
