Dollar General (DG) Increased Traffic 2% and Expanded Gross Margin. How Much Improvement Was Temporary?

Dollar General Corporation (NYSE: DG ) reported a quarter that combined stronger customer demand with a large temporary margin benefit. Second-quarter net sales increased 5.2% to $11.3 billion. Same-store sales increased 3.5%, reflecting a 2.0% increase in customer traffic and a 1.5% increase in average transaction amount. Same-store sales increased across consumables, seasonal merchandise, home products, and apparel, giving the sales recovery a broader base than traffic growth alone.

Gross margin increased to 32.6% from 31.3%, an expansion of 127 basis points. However, tariff refunds contributed approximately 81 basis points after gross-margin-related reinvestments. Mechanically removing that benefit leaves about 46 basis points of expansion excluding the refund benefit, meaning nearly two-thirds of the reported improvement came from refunds.

The remaining margin improvement still matters. Dollar General Corporation (NYSE:DG) attributed the reported expansion to tariff refunds, a lower LIFO provision and lower distribution costs, partly offset by higher markdowns and transportation costs. Dollar General Corporation (NYSE:DG) also reported continued improvement in shrink and damages despite comparing against a prior-year quarter that already included substantial shrink gains.

Dollar General Corporation (NYSE:DG) said combined non-consumable same-store sales grew 4.5%, supporting a more favorable merchandise mix.

Inventory discipline provides another encouraging signal. Merchandise inventory remained at $6.6 billion and declined 2.7% on an average per-store basis, even as sales increased. Operating profit rose 29.2% to $769.2 million, while year-to-date operating cash flow reached $1.5 billion. The tariff refunds contributed an estimated 66 basis points to operating margin and $0.25 to diluted earnings per share after related reinvestments, but results exceeded management's expectations even before that benefit.

Dollar General Corporation (NYSE:DG) raised fiscal 2026 guidance. Net sales are now expected to grow 4.0%-4.3%, compared with the previous 3.7%-4.2% range. Same-store sales guidance increased to 2.5%-2.9% from 2.2%-2.7%, while diluted earnings per share guidance rose to $7.80-$8.00 from $7.20-$7.45. The revised earnings outlook includes the $0.25 refund benefit.

The temporary component was substantial. Dollar General Corporation (NYSE:DG) received most of the anticipated tariff refunds during the second quarter and does not expect a material refund benefit after reinvestments during the second half. The 46-basis-point gross-margin expansion excluding the refund benefit is positive, but much smaller than the reported 127-basis-point increase. A lower LIFO provision may also provide less durable support than improvements in shrink or distribution productivity.

Transportation and fuel costs remain headwinds. Dollar General Corporation (NYSE:DG) expects elevated fuel costs during the second half, while higher markdowns also offset part of the quarterly margin improvement. The core lower-income customer remains financially constrained by inflation and volatile fuel prices. Trade-down activity from middle- and higher-income shoppers supports demand, but it also reflects a pressured consumer environment.
