ZKH (ZKH) Q4 2025: SME Customer Base Expands 60%, Fueling Margin Tailwinds and Profit Inflection
ZKH’s fourth quarter marked a decisive inflection as profitability returned and SME-driven growth accelerated, signaling a post-optimization business reset. The company’s multi-pronged strategy—spanning private label expansion, AI-driven operational gains, and a broadened customer footprint—has begun to deliver structural improvements, with management targeting full-year profitability in 2026. Investors should watch for sustained margin recovery and the scaling impact of automation and digital intelligence on ZKH’s evolving business model.
Summary
- SME Customer Surge: Transacting SME customers grew 60%, powering double-digit GMV gains.
- AI-Driven Efficiency: Automation and digital tools materially improved operating leverage and labor productivity.
- Profitability Pivot: Management signals confidence in achieving full-year profitability as business mix and cost structure improve.
Performance Analysis
ZKH exited 2025 with a marked turnaround in both top-line growth and profitability, as the company’s strategic optimization efforts transitioned from headwind to tailwind. Q4 delivered solid revenue and GMV acceleration, with GMV up 8.5% year over year and 11% sequentially, reflecting broad-based demand recovery across key accounts and SME segments. Notably, the number of transacting customers surged to nearly 74,000—a 60% increase—driven by a blend of digital marketing, regional network expansion, and AI-enabled customer targeting.
While gross margin compressed to 15.5% amid product mix shifts and higher SOE (state-owned enterprise) volume, structural drivers such as SME and private label growth provided a positive margin outlook. Operating expenses fell 3% year over year, yielding improved operating leverage and a return to positive EBITDA and net profit for the quarter. Cash flow from operations was robust, further strengthening ZKH’s liquidity and financial flexibility.
- Customer Mix Shift: SME and key account GMV both grew over 20% YoY, with SME momentum outpacing legacy segments.
- Private Label Expansion: Private label GMV rose 21% YoY, increasing its share of GMV to 8.3% from 6.7%.
- Operational Efficiency: Warehouse fulfillment costs declined by 13%, and labor productivity improved 20% YoY.
Despite margin pressures from commodity-driven product mix changes, ZKH’s underlying business quality improved, setting the stage for sustainable margin expansion as higher-value segments scale.
Executive Commentary
"Both GMB and revenue largely recovered to prior year levels in the third quarter, then accelerated into solid year-over-year growth in the fourth quarter. At the same time, our earnings quality continued to strengthen. We successfully returned to profitability in the fourth quarter with an adjusted net profit of 14.8 RMB million... These results signal that we have moved past the transitional effects of strategic optimization and entered a healthier, more resilient phase of development."
Eric Chen, Founder, Chairman & CEO

Strategic Positioning
1. SME and Key Account Penetration
ZKH’s core growth engine has shifted decisively toward SME customers, supported by digital marketing, regional service expansion, and AI-driven customer acquisition. SME GMV rose over 20%, and key account coverage now exceeds 680 of China’s top 1000 manufacturers, with industry verticals like electrical, chemical, and transport each exceeding 20% GMV growth.
2. Private Label and Product Mix Evolution
Private label, ZKH’s in-house product line, expanded rapidly, with 349 new SKUs launched in Q4 and GMV share rising to 8.3%. Management targets 10% GMV share in 2026, with a long-term goal of 30%. This shift not only drives customer loyalty and supply chain control but also supports margin expansion as the mix tilts toward higher-value, differentiated offerings.
3. AI and Automation as Competitive Moat
ZKH’s AI strategy—spanning data infrastructure, domain-specific models, and scenario applications— is now a core differentiator. The H-NIMBL model, tailored for MRO (maintenance, repair, and operations) procurement, and RPA (robotic process automation) digital workforce (now exceeding 5,000) have delivered a step change in process automation, cost reduction, and customer service productivity. Token usage, a proxy for AI workload, is expected to grow tenfold in the next 2-3 years, further embedding digital intelligence across the business.
4. Fulfillment Network Optimization
Warehouse and delivery network rationalization has driven eight consecutive quarters of double-digit fulfillment cost reductions. ZKH now operates 30 distribution centers, over 100 transit warehouses, and a fleet of 200+ vehicles, supporting both national and international expansion (now in 17 countries).
5. International Expansion
The overseas business showed 50% sequential GMV growth, with customer count up 20% and fulfillment network extended to 17 countries. Management plans to deepen local capabilities and leverage China’s manufacturing export wave as a long-term growth lever.
Key Considerations
ZKH’s Q4 results highlight a company at a structural inflection, with profitability and operating leverage returning as SME, private label, and AI initiatives scale. However, the path forward will require careful navigation of product mix volatility and continued execution on digital transformation.
Key Considerations:
- Margin Leverage from SME and Private Label: SME and private label mix are structural margin tailwinds, but commodity-driven product mix swings can mask progress quarter to quarter.
- AI as a Structural Cost Advantage: RPA and AI-driven process automation have already saved nearly 1 million man-hours, but scaling further will require ongoing investment in data and model quality.
- Customer Base Diversification: SME and international market expansion diversify risk but also introduce new operational complexities and working capital demands.
- Fulfillment Cost Discipline: Sustained double-digit cost reductions in warehousing and delivery are critical for offsetting price and margin pressures in commoditized categories.
Risks
Gross margin volatility remains a near-term risk, with Q4 impacted by low-margin commodity categories and a higher mix of SOE customers. Management expects gradual margin recovery, but external shocks (such as oil price spikes or supply chain disruptions) could pressure margins and cash flow. Scaling AI and automation requires ongoing capital and talent investment, and competitive intensity in China’s industrial procurement space may challenge customer retention and price discipline.
Forward Outlook
For Q1 2026, ZKH expects:
- Double-digit year-over-year GMV growth, driven by SME and international expansion.
- Gradual margin recovery as product mix normalizes and private label share rises.
For full-year 2026, management is targeting:
- Return to full-year profitability, supported by margin expansion and cost discipline.
- Private label share of GMV to reach 10%, with a 30% growth target in private label GMV.
Management emphasized continued investment in product, supply chain, and AI capabilities, alongside disciplined working capital and cost management, as the foundation for sustainable growth.
- Focus on deepening SME penetration and customer quality improvement.
- Acceleration of AI product launches and automation initiatives.
Takeaways
ZKH’s Q4 marked a structural pivot, with SME and private label scaling, AI-driven cost advantages, and a renewed profitability trajectory.
- Business Mix Shift: SME and private label growth are now the primary levers for both revenue and margin expansion, offsetting legacy and commodity category headwinds.
- Digital Transformation: AI and automation are delivering tangible cost and productivity gains, with further upside as digital capabilities deepen.
- Execution Watchpoint: Investors should monitor the pace of margin recovery, the scaling of international and SME businesses, and the sustainability of operational efficiency gains.
Conclusion
ZKH’s fourth quarter confirms a business model reset, with profitability restored, SME and private label scaling, and AI-powered efficiency gains underpinning a more resilient growth trajectory. Execution on digital transformation and disciplined cost management will be critical to sustaining this momentum through 2026 and beyond.
Industry Read-Through
ZKH’s results signal a broader shift in China’s industrial distribution landscape, where digital platforms leveraging AI, automation, and private label strategies are gaining share against legacy procurement models. The company’s success in scaling SME and international business, alongside AI-driven operational gains, highlights the competitive imperative for digital transformation and supply chain integration across the sector. Players lacking digital scale or automation risk margin compression as the industry moves toward higher efficiency and customer-centric models. The read-through is clear: AI, private label, and fulfillment agility are now table stakes for industrial distribution leadership in China and potentially other emerging markets.
