Under Armour’s 25% SKU Cut Is a Supply Chain Simplification Play, Not Just Merchandising

Under Armour's decision to cut a quarter of its SKUs is easy to frame as a merchandising reset. The better read is operational: fewer products can mean cleaner inventory, simpler warehouse execution, tighter replenishment, and less transportation noise.

According to Supply Chain Dive, Under Armour has reduced 25% of its SKUs over the last two years as CEO Kevin Plank pushes the brand toward “fewer, better products.” CFO Reza Taleghani told analysts the work is “not just lower inventory, but better inventory,” driven by tighter buys, a more focused assortment, and stronger demand alignment. The company ended its fiscal year with $915 million in inventory, down 3% year over year.

That distinction matters. Cutting SKUs is not automatically good. A retailer can remove products and still create stockouts, lost sales, awkward substitutions, and frustrated customers. The win comes when assortment decisions reduce bad complexity: items with weak velocity, poor margin, high handling costs, confusing demand signals, or disproportionate return exposure.

SKU rationalization changes the operating model

Every SKU carries a supply chain footprint. It needs a supplier setup, purchase order logic, carton dimensions, slotting rules, replenishment parameters, safety stock assumptions, transportation routing, receiving checks, return disposition, and sometimes special packaging or labeling. Multiply that by thousands of slow-moving items and the catalog becomes a hidden tax on the network.

For apparel, that tax gets heavier because size, color, style, and seasonal variation create long-tail complexity. A single product family can become dozens of active SKUs before the logistics team ever touches a carton. If demand is fragmented across too many variants, planners are forced to spread buys thinly, warehouses hold more partial positions, and stores or e-commerce channels chase inventory that is technically in the network but not where demand appears.

Under Armour's “fewer, better products” language points to a healthier model: concentrate demand around items that deserve operational priority. That can improve forecast quality because demand signals are less diluted. It can improve inventory quality because capital is not trapped in low-velocity variants. It can improve warehouse productivity because slotting teams can allocate prime locations to products that actually move.

The result is not just a smaller catalog. It is a simpler flow of goods.

The broader retail pattern is getting clearer

Under Armour is not alone. Dollar General has cut more than 1,500 SKUs over the last few years, Supply Chain Dive reported in a separate article on the retailer's inventory program. The company said Q4 merchandise levels were down 5.7% year over year, a $379 million reduction, while stores averaged a 7% decline in inventory levels. Just as important, Dollar General said in-stocks improved by roughly 250 basis points year over year.

That is the signal logistics teams should care about: inventory can come down while availability improves if the assortment gets cleaner. Fewer SKUs do not have to mean less reliable service. Done well, they can mean better focus on the products customers actually buy.

The same article noted that Bath & Body Works has been simplifying categories after customers found stores overwhelming, while Lowe's has pursued a goal of cutting 15% of SKUs. In food manufacturing, Supply Chain Dive reported that brands are also rethinking portfolios, with Kearney's Mihir Tamhankar describing a shift toward fewer SKUs with larger targeted pushes. Bain partner Dheera Anand framed the issue as separating “good complexity” that drives growth from “bad complexity” that adds cost without enough benefit.

That is exactly the right lens. Assortment complexity is not evil. Customers need choice, brands need differentiation, and some long-tail products create real loyalty. But complexity has to earn its keep. If a SKU creates extra touches, poor cube utilization, emergency replenishment, higher returns, and weak sell-through, its gross margin is probably overstating its true value.

What changes in the warehouse

The most immediate logistics impact is slotting. Fewer active SKUs allow warehouse teams to reduce scattered pick faces, consolidate locations, and give high-velocity items better placement. That can shorten pick paths and reduce the number of exceptions created by tiny balances sitting in inconvenient locations.

Receiving gets cleaner too. A focused assortment usually means fewer inbound line items, fewer item-master errors, fewer vendor compliance edge cases, and simpler quality checks. That matters when distribution centers are already managing labor pressure and tight dock schedules.

Inventory control also improves. Cycle counting thousands of marginal SKUs burns time without necessarily reducing business risk. When the assortment is sharper, teams can spend more attention on high-value, high-velocity, or service-critical products. Accuracy improves where it matters most.

Returns are another underappreciated benefit. In apparel, poorly performing variants often return at higher rates because sizing, style expectation, or channel presentation is off. Removing weak variants can lower reverse-logistics volume and reduce the amount of inventory that has to be inspected, repackaged, discounted, or liquidated.

Transportation gets less noisy

SKU reduction can also improve freight economics, though not automatically. If a retailer simply cuts products without redesigning replenishment rules, the network may keep moving the same number of shipments with fewer units. The logistics team has to convert assortment simplification into transportation simplification.

That means checking cube impact first. Which discontinued SKUs were inefficient to pack or palletize? Which remaining products can ship in fuller case quantities? Which vendors can now consolidate purchase orders into fewer, denser inbound moves?

Replenishment frequency is next. A smaller assortment can support cleaner ordering patterns, but only if planners reset minimum order quantities, safety stock, and review cycles. Otherwise, old parameters continue to generate small, expensive shipments.

Vendor agreements need attention as well. When a retailer cuts the tail, supplier minimums and pack-size assumptions may no longer fit the new demand profile. Logistics and procurement should renegotiate around the future assortment, not the historical catalog.

Finally, transportation teams should monitor returns exposure by SKU family. A rationalization program that lowers outbound complexity but leaves a messy reverse flow has only solved half the problem.

A practical checklist for logistics teams

For shippers watching Under Armour's move, the playbook is straightforward:

• Identify SKUs with high logistics cost-to-serve, not just low sales.
• Model warehouse cube, pick-location, and replenishment impacts before final cuts.
• Reset vendor MOQs, lead times, and inbound consolidation rules after assortment changes.
• Track whether fewer SKUs actually improve in-stock performance and order cycle time.
• Compare return rates before and after rationalization, especially for apparel and seasonal categories.
• Update TMS and WMS master data quickly so discontinued products stop creating planning noise.

The companies that get this right will treat SKU reduction as a cross-functional operating change, not a one-time merchandising cleanup. Merchants may decide what stays in the catalog, but logistics determines whether simplification turns into measurable performance.

Under Armour's 25% cut is a useful reminder: the best supply chains are not always the ones carrying the most choice. They are the ones that know which choices are worth the operational cost.
