ZKH Group (ZKH) Q2 2026 earnings review
Operating Profit Reached as Growth Accelerates
ZKH Group achieved a major milestone in Q2 2026, reporting its first-ever GAAP operating profit (RMB 4.0M) as strategic pivots toward high-margin segments paid off. The top line is accelerating aggressively, with GMV surging 18.9% YoY and Net Revenues growing 12.8%, driven by a 50.7% spike in Marketplace (3P) volume and strong SME demand. Gross margins expanded 110 bps to 17.6% due to private-label growth. However, beneath the strong headline numbers, operating cash flow remains negative and total transacting customers actually declined YoY, indicating the top-line beat is driven by deeper wallet share rather than a widening base.
🐂 Bull Case
The transition to profitability is structural. Operating expenses as a percentage of revenue dropped to 17.4% from 19.8% a year ago, leading to the company's first GAAP operating profit.
Marketplace (3P) GMV exploded 50.7% YoY, and private-label products grew >25% YoY to hit 10% of total GMV. This mix shift directly drives the 110 bps gross margin expansion.
🐻 Bear Case
Despite achieving positive net income, Operating Cash Flow was negative RMB 122.4M (worse than the RMB 110.7M outflow last year), weighed down by climbing accounts receivable.
Total transacting customers fell 1.7% YoY to 73,547. The impressive GMV growth is reliant on existing customers spending more, which limits long-term total addressable market penetration.
⚖️ Verdict: 🟢
Bullish. Achieving GAAP operating profit while simultaneously accelerating top-line growth to 18.9% GMV is exactly what investors want to see from a scaling B2B platform. If they correct the cash flow drag, the fundamental thesis is highly intact.
Key Themes
Inflection to GAAP Operating Profitability
Reversing a trend of consistent losses, ZKH generated RMB 4.0M in GAAP operating profit (0.2% margin), compared to a RMB 72.0M loss a year ago. Non-GAAP EBITDA swung from negative RMB 38.7M to a positive RMB 41.9M. This was achieved through massive operational leverage: total operating expenses dropped 0.8% absolutely, despite GMV scaling by nearly 19%.
Marketplace (3P) and SME Segments Driving Growth
Accelerating. The asset-light Marketplace (3P) model was the undisputed growth engine this quarter, with GMV surging 50.7% YoY to RMB 431.5M. Meanwhile, GMV from SME customers grew approximately 30% YoY. These two cohorts are structurally higher-margin and are the primary reason gross profit grew much faster (+20.3%) than net revenues (+12.8%).
Private-Label Product Margin Engine
Accelerating. The company scaled its higher-margin private-label products by adding over 700 SKUs during the quarter. Private-label GMV grew more than 25% YoY and now accounts for approximately 10% of total GMV. This initiative is directly responsible for the 50 basis point sequential gross margin improvement on a GMV basis.
Domino AI Data Engine Boosting Efficiency
AI integration is producing measurable results. ZKH launched 'Domino', a billion-parameter industrial supplies data engine, and reported that AI now supports >70% of R&D coding. Company-wide AI adoption generated an estimated 12,759 hours of productivity gains in Q2. AI Materials Manager users surged 200% YoY to over 8,000.
Operating Cash Flow Disconnect
A notable red flag: despite Net Profit swinging to a positive RMB 26.7M, Operating Cash Flow worsened to a negative RMB 122.4M (from -110.7M a year ago). The balance sheet shows Accounts Receivable climbed from RMB 3.26B at year-end to RMB 3.45B, indicating that growth is consuming significant working capital and requiring extended credit terms.
Customer Count Contradicts Growth Narrative
Despite GMV accelerating to 18.9% growth, the actual number of transacting customers declined 1.7% YoY to 73,547. While increasing wallet share with existing Key Accounts (KAs) and SMEs is positive, failing to expand the absolute customer base in China's highly fragmented MRO market is a concerning signal for long-term user acquisition.
GBB Platform Contraction
Decelerating/Reversing. While the flagship ZKH Platform grew GMV by a robust 22.9%, the secondary GBB Platform saw GMV decline 12.1% YoY to RMB 242.5M. The company did not explain this divergence, but it indicates severe weakness in the non-core platform offering.
China Macro and KA/SOE Resilience
Despite a choppy macro environment in China, ZKH noted that Industry Key Accounts (KAs) and central State-Owned Enterprises (SOEs) sustained healthy double-digit growth. Core verticals like communications, electronics, and fine chemicals outpaced average platform growth, proving resilience in advanced manufacturing.
Other KPIs
Accelerating. Up 110 basis points YoY from 16.5%. Driven by scaling higher-margin private-label products and a massive 50.7% volume surge in the asset-light 3P Marketplace business.
Accelerating efficiency. Fulfillment as a percentage of revenue declined by 50 basis points YoY to 3.7%. Absolute costs actually dropped 1.3% YoY despite an 18.9% increase in GMV, demonstrating exceptional warehouse utilization and delivery network leverage.
Accelerating. While still off a small base, International GMV increased tenfold YoY in the first half of 2026, supported by local US operations and Chinese manufacturers expanding overseas.
Guidance
Accelerating. Management explicitly expects "growth to accelerate further in the second half of the year." Given Q2's 18.9% GMV print, this implies expectations of 20%+ YoY growth in the coming quarters.
Key Questions
Customer Acquisition Stagnation
Despite GMV accelerating to nearly 19% growth, transacting customers fell 1.7% YoY. Is this an intentional optimization of low-value accounts, or are you facing headwinds in net new logo acquisition?
GBB Platform Decline
The GBB platform saw a 12.1% YoY decline in GMV while the main ZKH platform grew 22.9%. What is driving this divergence, and what is the strategic future for the GBB platform?
Working Capital & Cash Burn
With the business achieving GAAP operating profitability, operating cash flow remained negative at RMB 122.4M due to climbing accounts receivable. When do you expect working capital dynamics to normalize so operating cash flow turns positive?
