Dollar General: The AI Rollout Is Real, but Tariff Refunds Did the Heavy Lifting

On the morning of August 27, Dollar General delivered two announcements at once. The first: it reported second-quarter results that beat, with earnings of $2.48 a share versus the roughly $2.00 analysts expected, net sales up 5.2% to $11.3 billion, and a raise to its full-year forecast. The second: it is rolling out an AI-based forecasting and replenishment system, built with RELEX Solutions, across more than 21,000 stores and 34 distribution centers. Shares jumped in premarket trading and then gave most of the gain back; the stock sits near $126, roughly 20% below its 52-week high.

That muted reception is the market sorting the two stories apart, which is the right instinct. The AI rollout is real and worth taking seriously. It is also not what paid for the quarter.

The refund is the number that matters first

Dollar General's gross margin expanded 127 basis points to 32.6%. Roughly 81 of those basis points came from tariff refunds — money the government returned for duties the company previously paid, net of the price reinvestments it made — and management said most of the benefit arrived in the second quarter, with no material impact expected in the second half. The refunds were an industry event, not a company skill: retailers reported more than $5 billion in federal tariff refunds in earnings released in a single week, part of a wave that topped $9.6 billion across more than 40 S&P 500 companies.

This changes how to read the beat. Tariff refunds added about $0.25 to quarterly earnings per share and about 66 basis points to operating margin. Take that out and the quarter is still real — higher inventory markups, continued shrink improvement, a lower LIFO provision and lower distribution costs outweighed more markdowns and higher transportation costs — but it becomes a good quarter rather than the blowout the headline number suggests. The raised full-year guidance of $7.80 to $8.00 per share carries the same one-time $0.25 embedded inside it. First-half earnings were $4.48 — $2.00 in Q1 plus Q2's $2.48 — and the raised range implies second-half earnings of roughly $3.32 to $3.52, barely above the $3.21 delivered a year ago. The windfall is being banked, not compounded.

Where the AI story actually fits

The RELEX partnership consolidates forecasting, replenishment and allocation onto one AI-driven platform across the chain's roughly 18,000 SKUs. For a business of this scale the pitch is straightforward: better demand forecasts mean fewer out-of-stocks — a lost sale for a value retailer whose customer usually arrives wanting one specific cheap item — and less inventory lingering long enough to be stolen or marked down. It is a supply-chain productivity and working-capital story, not a sales story.

And it connects to refund-independent evidence already visible in the numbers. Comparable sales rose 3.5%, driven by 2.0% customer traffic growth, the fifth straight quarter of traffic gains, and management called it the best two-year comparable stack in three years. Merchandise inventory stayed roughly flat year over year while sales grew, so per-store inventory fell 2.7% — extending the same discipline that ended fiscal 2025 with per-store inventories down 7%. Dollar General has also removed more than 1,500 SKUs over the past few years to improve in-stocks. Shrink — inventory lost to theft and error — was again a meaningful driver of the margin gain.

Here is the discipline problem with the headline. On the same call, executives made clear the AI work is not yet in the financial model: the company is "still early in our AI journey," and its long-term financial framework does not currently contemplate any benefit from AI. Jeff Vaughan, Dollar General's SVP of global inventory management, called RELEX a "practical way to use AI in planning" that gives teams "greater visibility across the network." That is direction, not numbers. The press release and the profit-and-loss statement are not connected yet, and management declined to bridge them.

The multiple already prices the recovery

So what is the stock worth for what is actually real? At about $126, Dollar General trades at roughly 16 times the midpoint of its newly raised guidance, about in line with Target's roughly 17 times trailing earnings, and a long way from the deep-discount multiple you would expect for a stock down about 14% over the past four months. The setup underneath is respectable: a roughly 1.9% dividend paying out about 30% of earnings, on the order of $2 billion of annual free cash flow, a debt-to-EBITDA target below 3x, and share repurchases restarting with up to $700 million authorized for the second half.

The valuation question is whether the market is wrong to stay lukewarm. Operating margin reached about 6.8% this quarter including the refunds — around 6.1% without them — versus about 5.2% for all of fiscal 2025. For scale: Dollar General earned $6.85 a share in fiscal 2025, up 34%, and now guides fiscal 2026 to $7.80 to $8.00, against its own long-term framework calling for operating margin of 6% to 7% beginning in fiscal 2028/29. One quarter is not a run rate, but the gap between the framework and today's actual margins is closing faster than the company itself planned. If that trend is real, 16 times is not expensive for a mid-teens EPS grower whose buyback has returned.

What would change the call

The honest verdict here is wait-and-see, and that is acceptable: the market is not obviously wrong, and the AI news is not a reason to buy by itself. The proof window is the next two quarters, because they have to be earned without tariff refunds. What would make the stock more interesting: second-half comparable sales holding near 2% to 3% with gross margin at or above roughly 31.5% on an operating basis; per-store inventory still falling while in-stock rates improve, the first visible sign the RELEX work is changing operations; and operating margin tracking toward the 6%-7% band on ordinary leverage rather than on a refund. What would break the case: comps fading below 2%, the shrink improvement reversing, another round of tariffs squeezing cost of goods, or Walmart and Amazon promoting more aggressively on the same consumables.

Dollar General has repaired much of what was broken — both the business and the stock have recovered sharply off the bottom — and investors are already paying a fair price for that repair. The AI deal gives the story direction. It does not yet give it a number. The next two quarters have to prove the margin without the refund.
