Walmart stock drops 9%: WMT comps slow to 2.6% despite EPS beat

Walmart stock does not usually move 9% in a day. When it does, markets are reading the print as a consumer weather report, not a rounding error on Bentonville’s P&L. Aug. 20 delivered exactly that: a clean revenue and EPS beat wrapped around the softest U.S. same-store growth in six years. The tape chose the soft part.

What Walmart stock did on Aug. 20

WMT sold off roughly 9% after the open, dragging consumer staples and putting pressure on peers — TJX slipped modestly; Target barely moved. Shares had already given back ground from a ~$135 52-week high into the mid-$100s; the earnings gap pushed price near the $104 area in Aug. 20 coverage, about 17% off the six-month peak in some trackers.

The Dow’s broader Aug. 20 drop (about 700 points) mixed Walmart with bond-yield and oil jitters. WMT was the retail headline, not a side note.

The beat that still felt like a miss

Q2 FY27 (ended late July / early August cycle) versus consensus:

• Revenue: $187.9 billion vs ~$186–186.8 billion expected
• Adjusted EPS: $0.81 vs ~$0.74 expected
• U.S. comps: +2.6% vs ~3.5–3.8% expected
• Global eCommerce: +23%

GAAP net income fell year over year to about $6.37 billion ($0.80/share) from $7.03 billion ($0.88), reminding holders that adjusted beats and reported income can tell different stories in the same quarter.

Why 2.6% comps rattled investors

Comparable sales are the metric premium retail multiples live and die on. At 2.6%, Walmart printed its slowest U.S. comps since Q4 2020 — pandemic-era territory for a company that spent the mid-2020s taking share from everyone.

Strip out the health-and-wellness / pharmacy pricing headwind (about 80 basis points) and comps would have been closer to 3.4% — still down from 4.1% in Q1 and still short of the Street. Transactions grew; ticket and category mix did not deliver the growth investors had priced in.

CFO John David Rainey said shoppers are making “trade-offs” amid high fuel costs — fewer discretionary baskets, more grocery and essentials focus. That is classic late-cycle Walmart behavior; the market hated seeing it show up this clearly while the stock still traded at a premium multiple.

Fuel costs and pharmacy pricing drag

Two structural headwinds dominated the call narrative:

• Fuel: Walmart expects more than $2 billion in incremental fuel-related costs above original guidance this year — Iran-Gulf shipping risk and elevated diesel/gasoline prices feed both store logistics and customer wallet share. See related pump pressure in diesel price 2026.
• Pharmacy / health & wellness: New drug-pricing rules cut U.S. comps by ~80 bps. Sales in the U.S. pharmacy business declined; that line item used to be a growth contributor.

Neither issue is a one-week weather blip. Fuel stays elevated while Hormuz risk and energy markets remain unsettled after the UAE Iran trade embargo. Pharmacy regulation is policy, not a promotion calendar.

$2.9B tariff refunds — one-time juice

Walmart received roughly $2.9 billion in IEEPA / tariff-related refunds — about 0.5% of U.S. annual sales — and said it has received substantially all of that pot. Management reinvested into price leadership: cuts on about 11,000 items, with grocery and general merchandise prioritized. Gross margin rose ~96 bps in the quarter, driven largely by the refund.

Rainey urged investors to judge Q2 and Q3 together because price investments funded by refunds hit margins and comps with a lag. Translation: Q2 looked better on adjusted EPS partly because of a windfall; Q3 guidance embeds continued price investment and looks softer by design.

One-time refunds do not recur. Walmart stock holders who treat $0.81 adjusted EPS as a new run-rate will get burned when that juice fades.

Raised FY guide, soft Q3 EPS

Outlook as of Aug. 20:

• Q3 net sales growth: 3.0%–3.75%
• Q3 adjusted EPS: $0.62–$0.64 (Street had been higher into the print)
• FY27 net sales growth: raised to 4.0%–5.0% (from 3.5%–4.5%)
• FY27 adjusted EPS: $2.80–$2.87 (raised from $2.75–$2.85, but below some prior consensus near $2.97)

Raising the top line while guiding earnings below what bulls wanted is the classic “good news, bad news” package. Walmart stock sold the bad news.

What the print says about the U.S. consumer

Walmart is still the bellwether. When its U.S. comps decelerate this sharply, the read-across hits Target, dollar stores, and discretionary retail. Management insists the consumer is “resilient” — shopping, just choosing carefully. That can be true and still leave WMT’s premium valuation unsupported if 2–3% comps become the new normal.

Higher long-term yields and sticky inflation (the same tape that knocked the Dow Aug. 20) squeeze household budgets the same way $4+ diesel squeezes them. Retail and rates are not separate stories this month.

What WMT holders watch next

Checklist into Q3:

• U.S. comps — does 2.6% stabilize near 3%+ once pharmacy noise clears?
• Tariff-refund burn rate — how much price investment remains after Q3?
• Fuel cost guide — $2B+ incremental already; any upward revision?
• Holiday inventory and promotions — early Q3 guide is the setup for Black Friday math
• Multiple compression — if premium valuation re-rates toward slower growth peers, absolute EPS can rise while the stock stays flat

Walmart stock on Aug. 20 punished a comps miss inside a beat. That is what premium multiples do. The company still grew eCommerce 23% and raised full-year sales guidance — bulls will call the selloff overdone. Bears will say 2.6% comps are the real signal. The next print decides which camp was early.
