Zalando's 20.7% Q2 GMV Jump Masks the Real Risk: A Lower 2026 Guide

Zalando posted a strong quarter, but the market focused on the softer guide

Zalando's Q2 numbers were solid, but the more important signal was forward-looking. GMV grew 20.7% to 4.9 billion euros, and adjusted EBIT rose 10% to 205 million euros. At the same time, the company moved to the lower half of its previously communicated range for 2026 GMV and revenue growth. For investors, that shifted attention from the beat to the cut.

Why the guidance cut matters more than the beat

Bulls can still point to a business with momentum. Zalando followed a powerhouse 2025 performance, and the stock had already been down 20% since the start of the year. Bears, though, will argue that a guidance reset matters more than one strong quarter. That was especially true after the first full-year 2025 guidance for the combined group, when investors were looking for confirmation that the larger group would bring clarity and confidence.

ABOUT YOU synergies, B2B growth, and AI are showing up in the results

The better reading is not simply "great quarter, weak outlook." It is that several parts of the earnings base are becoming easier to model.

ABOUT YOU synergies are already helping EBIT

The clearest signal is that integration is producing real operating leverage, not just higher sales. Synergies from the ABOUT YOU acquisition contributed more than 10 million euros to Q2 adjusted EBIT. That matters because synergy dollars do more than lift one quarter: they can improve the earnings base if they persist as the combined business scales.

B2B is becoming the higher-value growth engine

B2B revenue grew 27.6% to 335 million euros, while B2B margin to 12.2%. That is the part of the story investors should watch most closely. Marketplace growth can be volatile if it depends heavily on price-sensitive demand, but stronger B2B profitability suggests Zalando's services and software mix is becoming more important. That is generally a better earnings profile than pure GMV growth.

AI is starting to show up as operating capacity

Zalando also reported that SCAYLE STUDIOS scales to more than 100 brands within 2.5 months of launch, allowing them to create fashion content digitally, cutting content production time by more than 95% and costs by around 90%. That does not prove monetization on its own, but it does point to a real capacity gain. If content creation becomes faster and cheaper, merchant adoption and marketplace efficiency can improve without a matching rise in costs.

The 2026 reset shifts the burden back to management

The quarter itself was not the problem. The issue was the frame of reference. After the first full-year 2025 guidance for the combined group, investors expected a clearer confidence test. Instead, Zalando said 2026 is now in the lower half of its previously communicated range. That does not break the story, but it does make the next few updates more important.

Combined guidance is still meaningful, just less generous

The combined group guidance remains substantial: GMV of 17.2 – 17.6 billion euros, revenue of 12.1 – 12.4 billion euros, and adjusted EBIT of 550 – 600 million euros. But the market is trading the change in expectations, not just the absolute targets. Reuters had previously cited GMV growth of 12% to 17% in 2026, and adjusted EBIT of 660 million to 740 million euros in 2026. So the issue is not a collapse in prospects. It is that the ceiling got lower just as investors wanted proof that the merged business could expand the upside.

Why the bull case still exists

Bears can argue that fashion e-commerce is entering a softer phase, and the lower guide leaves room for that view. Bulls, though, still have evidence to point to: Zalando has 10 million users engaging with its AI assistant, and management has backed the long-term case with share buybacks as key elements of its plan to create long-term shareholder value. That keeps the debate about rerating, not survival.

What next needs to prove the thesis

Q2 showed that the combined engine can still grow profitably. The next updates need to show that earnings can improve faster than market patience runs out.

The main watchpoints

• Merged growth needs to hold. The key test is whether the combined group can stay on track for GMV of 17.2 – 17.6 billion euros and revenue of 12.1 – 12.4 billion euros.
• EBIT leverage must show up clearly. Investors should watch whether adjusted EBIT keeps moving toward 680 million to 720 million euros as ABOUT YOU synergies continue to flow through.
• B2B has to remain the higher-quality engine. After B2B margin to 12.2%, the next question is whether profitability holds as the segment keeps scaling.
• SCAYLE and ZEOS need continued proof of scale. That includes merchant adoption in SCAYLE STUDIOS and deeper connectivity through ZEOS.
• AI usage has to translate into productivity. The 10 million users figure is a meaningful adoption signal, but investors also need to see whether that engagement improves conversion, lowers content costs, or lifts operating efficiency.

The core thesis is still intact: Zalando has growth, integration progress, and new platform levers. But the next rerating now depends on evidence that those advantages are becoming more visible in earnings, not just in headlines.
