Key Drivers of US Foods' Q1 2026 Gross Margin Performance

Key factors driving US Foods’ gross margin performance in Q1 2026

US Foods described adjusted gross profit as rising to $1.7 billion (+4.4% YoY), which management attributed primarily to volume growth and improved cost of goods sold (COGS), including benefits from its vendor management program. ¹ Management also emphasized that it is progressing on “self-help” initiatives aimed at additional cost of goods savings, while reinvesting a portion of those savings to accelerate growth. ¹

Below are the main drivers of gross margin performance highlighted in the Q1 2026 materials.

---

1) Higher volume (including independent restaurant momentum)

Management stated that adjusted gross profit increased and that this was driven by volume growth. ¹

Consistent with that, the company reported Q1 net sales up 2.8% to $9.6 billion, driven by total case volume growth of 1.4% plus food cost inflation and mix of 1.4%. ² The company also reported that independent restaurant volume grew 4.6% (including contributions from acquisitions). ² Separately, management noted profitable volume growth and that adjusted EBITDA growth was driven by volume growth and progress on self-help initiatives to improve gross profit. ²

Why this matters for gross margin: gross profit at the “gross margin” level benefits when higher case volumes spread fixed/semifixed distribution and purchasing-related costs over more units, and when volume aligns with targeted customer types that management believes support better margins. ²

2) Improved COGS / cost of goods sold through vendor management and savings programs

US Foods explicitly linked gross profit growth to “improved cost of goods sold” and cited progress from strategic vendor management aimed at generating additional cost of goods savings. ¹

Management also quantified longer-term objectives: it expects at least $300 million in cost of goods savings over a three-year plan ending in 2027, which is up from an original $260 million commitment. ¹

Why this matters: lower COGS (or better pricing/mix/contract performance) directly lifts gross margin dollars and gross margin rate, assuming sales mix and volumes don’t offset the benefit. US Foods also described private label as a related margin lever (see next section). ¹

3) Private label penetration and brand mix as a margin lever

US Foods emphasized private label brands as a growth and margin opportunity. ¹ Management reported private label penetration of 54% with core independent restaurant customers. ¹ It also stated private label is meaningful because it offers more cost-effective products (helping customers) and supports stronger margins for US Foods. ¹

In addition, management discussed the scale of its exclusive brands (e.g., “more than 22 brands and 10,000 products”) and described the sales force incentives designed to increase penetration, stating these brands are more profitable for US Foods Holding Corp. ³

Why this matters: private label mix typically improves gross margin because the distributor captures more margin via proprietary or exclusive product sourcing versus commoditized brands—an effect management directly tied to stronger margins. ¹

4) Gross profit per case outpacing operating expense pressure (a “margin quality” signal)

While the question is specifically about gross margin performance, US Foods’ commentary often connects gross margin improvements to the resulting operating profitability trend.

Management reported that adjusted gross profit per case increased by $0.23 (+2.9%) vs. prior year, and described the primary driver as self-help initiatives, including cost of goods sold work. ⁴ It also stated adjusted operating expenses per case increased by $0.14 (+2.3%) with $0.04 attributable to incremental expenses from weather and higher fuel. ⁴

US Foods then tied this to EBITDA per case: adjusted EBITDA per case increased by $0.08 to $1.98, because adjusted gross profit per case grew 60 basis points faster than adjusted OpEx per case. ⁴

Why this matters: gross margin improvement (gross profit per case) relative to operating cost per case is a strong indicator that gross margin gains were not merely offset by higher costs elsewhere. ⁴

5) Self-help reinvestment and productivity efforts supported gross margin, even amid weather/fuel disruptions

US Foods acknowledged a headwind-heavy quarter (weather and higher fuel costs), but management still pointed to self-help progress supporting gross profit and gross margin performance.

• It stated that as it realizes COGS savings, it reinvests a portion to accelerate growth. ¹
• It reported a 3% improvement in year-over-year warehouse and selector productivity, driven in part by UMOS (a supply chain process standardization/continuous improvement platform). ¹
• Management also explained that in the quarter, weather and higher fuel impacted EBITDA growth (estimated ~four percentage points reduction), but self-help progress still drove results. ²

Why this matters for gross margin: productivity improvements in warehousing/selection can reduce handling/operating costs tied to delivering product, supporting gross profit conversion even if they don’t change “gross margin” line items mechanically—US Foods connected its supply-chain operating system (UMOS) to productivity targets and overall margin expansion momentum. ¹²

Bottom line

In Q1 2026, US Foods’ gross margin performance (as reflected in adjusted gross profit and adjusted gross profit per case) was driven chiefly by:

1. Volume growth (including 4.6% independent restaurant volume growth) supporting gross profit dollars. ¹²
2. Improved COGS from strategic vendor management and cost of goods savings programs. ¹
3. Private label mix/penetration (54% penetration with core independent customers) supporting margin via more cost-effective products. ¹
4. Gross profit per case rising faster than OpEx per case, with the gross profit per case increase attributed primarily to self-help including COGS work. ⁴
5. Productivity and self-help execution (UMOS and warehouse/selector productivity) helping margin outcomes despite weather and fuel headwinds. ¹²

These are the factors management repeatedly emphasized as the direct drivers of gross margin performance in the quarter. ¹²⁴
