WD-40's 'Low Point' Has to Prove Itself

A 190-basis-point margin hit and a 27% drawdown collide with a cautious FY27 guide

The quarter that broke the margin streak

WD-40's fiscal fourth quarter was a clean split: demand held, margins did not. Consolidated net sales rose 8% to $177 million and full-year sales climbed 11% to $688 million; maintenance product sales, the metric management actually benchmarks, rose 9% in constant currency for the year, at the top of the 5%-9% long-term range. But Q4 gross margin fell to 52.8%, down 190 basis points year over year, as roughly 370 basis points of higher specialty-chemical and raw-material costs swamped a 170-basis-point benefit from lower aerosol-can costs and fill fees. Sara Hyzer did not soft-pedal it: “Fourth quarter gross margin was 52.8%, down 190 basis points from the prior year. This decline was primarily driven by approximately 370 basis points of higher specialty chemical and raw material costs.” — Sara Hyzer · 2026-10-21 The full year still landed at 55.3%, above the long-term target, which is why the call framed Q4 as an air pocket rather than a change in the model. The last filed quarter before this print showed how high the bar had become: gross margin of 56.6% with a 20.7% operating margin. Q4 gave back a chunk of that.

Nothing new under the sun—except the “low point”

The oil-cost problem is not a surprise. Three months ago, Hyzer told analysts the company had enough inventory to hold Q3 margins but expected cost increases to flow through in Q4, and that price increases would begin to take effect in fiscal 2027. She also warned about the asymmetry now central to the story: “the costs go up pretty fast, and then there is a slower pace for it to step down.” — Sara Hyzer, Vice President and Chief Financial Officer · 2026-07-09 On the April call, Steve Brass said management was “looking actively at mitigation, both in terms of potential price movement and further cost-saving initiatives” — Steven Brass, President and Chief Executive Officer · 2026-04-09. So the current quarter’s message is less a revelation than a confirmation. What is new is the attempt to call the floor. Brass said: “we believe the fourth quarter marked the low point for gross margin and we expect sequential improvement starting in the first quarter of fiscal 27.” — Steven A. Brass · 2026-10-21 The company now has a margin recovery narrative with a timetable: gradual improvement through FY27, acceleration in the second half, back toward the 55%-plus target if oil cooperates. The FY27 guide is 54%-55.5%, which at the midpoint is slightly below FY26’s 55.3%. That is not a victory lap; it is a “prove it” number. The low point language matters because it converts a cost problem into a test of credibility.

Our outlook assumes no material changes in the current economic environment. It also assumes crude oil prices remain near current levels through the first half of fiscal 27 before moderating in the second half.

That is a fragile assumption. The call’s own Q&A made clear that freight is also elevated, and that specialty-chemical inputs can decouple from crude. The oil price path is not a side issue; it is the swing factor between a mid-50s margin and another year of defense. Management is leaning on pricing, cost savings, premiumization, and trade-block mix. Those are real levers—FY26 delivered more than $7 million of supply-chain cost reductions—but they are slower-acting than spot input costs.

The growth story is slowing, not breaking

The other tension is growth. FY26 sales rose 11%, but FY27 guidance is 4%-7%, with $715-$735 million on a constant-currency basis. Management was explicit that the U.S. laps a very strong FY26 and should see “modest single-digit growth,” leaving Europe and Asia Pacific to carry more of the load. That is a deceleration, but not a demand break: Q4 maintenance sales rose 9% reported and 8% constant currency, with growth in all three trade blocks. The newer strategic item is Japan. WD-40 recently made Japan a direct market, its first direct move in Asia Pacific in 20 years. Brass framed it as a slow build but a real one: “in our first year, we do expect to somewhere between 2x and 4x, what were quite moderate sales in our FY 2026.” — Steven A. Brass · 2026-10-21 That is small in absolute dollars today, but it fits the long-running playbook of converting distributor markets into direct operations, as it did in Mexico and Brazil. It also gives Asia Pacific another growth layer beyond China, which management says continues to grow double digits. Digital remains a genuine bright spot. Pure-play e commerce channel sales rose 19% to $66.7 million and now represent 13% of global direct-market maintenance product sales. Brass also flagged a newer priority for FY27—making the brand easy to find across AI-powered search and recommendation tools—which is a sensible hedge as discovery shifts. The data-center construction boom came up in Q&A; Brass called it a strong growing use case for contact cleaners, white lithium greases, and other products, but it is not yet a needle-mover. The global tape has cooled on AI data center exposure over the last 30 and 90 days, so investors should treat that as optionality, not a base-case driver.

Why the tape matters

This report lands into a damaged stock. WDFC is down 14.9% over the last 90 trading days and 27.3% from its July 10 peak of $264.91, even though the long-term chart is still up massively over 15 years. For a $2.6 billion market-cap specialty-chemicals name with a premium multiple, that drawdown is the market’s way of saying it does not fully trust the “low point” call. The temporary cost pressure framing is plausible, but “temporary” has been the operative word for two quarters now. The global tape adds context: oil-linked equities appear among the 90-day advancers, with higher oil prices helping the energy complex. WDFC is not an oil producer; it is an oil-input consumer. So the same macro move that lifts energy stocks is a margin headwind here. That divergence explains why the stock can fall while parts of the commodity tape are firm. The company’s asset-light model, strong free cash flow—117% conversion of non-GAAP net income in FY26—and 28.6% ROIC remain intact, but FY27 is now a margin-recovery year before it is a growth story. The next two quarters are the tell. If gross margin improves sequentially from 52.8% and Q1 revenue starts with the high-single-digit to double-digit growth Brass described for September, the low-point thesis earns credibility. If oil stays sticky and freight remains elevated, the market will treat the 54%-55.5% guide as optimistic. WD-40 still looks like a durable compounder; it just has to prove that the fourth quarter was a trough, not a new baseline.
