Wallbox (WBX) Q2 2025: Backlog Expands €5M as Europe and Fast Charging Regain Momentum

Wallbox’s Q2 revealed a pivotal shift as backlog grew by more than €5 million, signaling renewed demand traction in both AC and DC charger lines, especially in Europe and North America. Margin stability and a 35% year-over-year cut in cash costs highlight disciplined operational execution, while new product launches and strategic partnerships set the stage for a stronger second half. Investors should watch for the company’s ability to convert backlog and sustain cost discipline as the European EV recovery accelerates and U.S. policy uncertainty looms.

Summary

  • Backlog Acceleration: Order backlog grew over €5 million, boosting near-term sales visibility and operational leverage.
  • Cost Discipline Outpaces Revenue: Cash costs fell 35% year-over-year, driving EBITDA improvement despite revenue softness.
  • Strategic Product Launches: Quasar 2 and virtual power plant initiatives position Wallbox for energy ecosystem expansion.

Performance Analysis

Wallbox delivered Q2 revenue of €38.3 million, in line with guidance, with Europe accounting for 68% and North America 30% of the total. European sales showed incremental quarter-over-quarter improvement, led by Spain and Italy, while North America maintained steady contribution amid a contracting EV market. AC charger sales, including ABL and Quasar, comprised 69% of revenue and grew 4% sequentially, though remained below last year’s record levels. DC charger sales stabilized after prior weakness, with backlog growth suggesting a potential inflection in the second half.

Gross margin held steady at 37.8%, as product mix and cost structure remained consistent. Operating leverage improved meaningfully: labor and operating expenses declined 25% year-over-year, and cash costs dropped 35%, reflecting aggressive efficiency measures. Adjusted EBITDA loss narrowed 33% from the prior year, though remained at negative €7.5 million, constrained by slower-than-expected OPEX reduction and freight/tariff costs tied to U.S. demand. Inventory reduction of 33% year-over-year further released cash, supporting operational flexibility.

  • Backlog Growth Signal: Over €5 million increase in backlog, with AC and DC orders driving future visibility.
  • Cash Cost Compression: 35% year-over-year reduction in cash costs, outpacing revenue contraction.
  • Margin Stability Amid Mix Shift: Gross margin maintained despite higher bill of material and freight costs.

Wallbox’s ability to sustain margin and cost progress while building backlog is a critical signal of operational control, with the next quarters hinging on backlog conversion and continued cost discipline.

Executive Commentary

"Most importantly, we built a significant backlog for both AC and DC, which increased by more than 5 million euros. We aim to continue building our backlog to increase sales visibility and, as a result, improve our operational efficiency."

Henrique Asuncion, Chief Executive Officer

"Even though we are making progress on the combined labor costs and OPEX results, this quarter showed a slight increase in OPEX due to additional freight, duty, and tariff costs. This was unexpected, as we had to react to the consistent high demand in the U.S. Going forward, we see opportunities to better manage and mitigate these variances for greater margin read-through."

Luis Boada, Chief Financial Officer

Strategic Positioning

1. Backlog and Sales Pipeline Expansion

Wallbox’s backlog grew by nearly €6 million in Q2, driven by both AC and DC product lines. This backlog build provides improved revenue visibility and operational planning confidence, especially as Europe’s EV market rebounds and North American partnerships deepen. The company is prioritizing backlog conversion, particularly in fast-charging segments (80-400 kW), where profitability and volume are highest for both Wallbox and charge point operators (CPOs, companies that operate EV charging infrastructure).

2. Product Innovation and Energy Ecosystem Integration

The launch of Quasar 2, a certified bidirectional charger, puts Wallbox ahead in the home energy management space, enabling EV batteries to serve as backup power and participate in grid flexibility programs. Virtual power plant (VPP, aggregated distributed energy resources providing grid services) pilots in California and New York further position the company as an energy ecosystem enabler, leveraging its installed base for recurring software and service revenue.

3. Geographic Diversification and Market Adaptation

Europe’s 30% EV market rebound is fueling renewed growth, with Spain and Germany now among the fastest-growing markets. North America remains critical, supported by partnerships with Stellantis, Generac, and others, though U.S. policy shifts and tax credit expirations introduce volatility. Wallbox’s resource allocation is increasingly dynamic, shifting sales and support investment to regions and channels with the greatest near-term opportunity.

4. Operational Efficiencies and Cost Structure Reset

Wallbox’s 25% reduction in labor and OPEX and 35% cash cost cut reflect a significant restructuring over the past year, including integration synergies from the ABL acquisition (ABL, German AC charger manufacturer). Inventory drawdown and CapEx discipline further support the company’s push toward EBITDA break-even, even at current revenue levels.

5. Strategic Partnerships and Channel Expansion

Ongoing collaboration with Generac in North America and Pramac in Europe is yielding both product integration and sales channel expansion. The rollout of fast-charging solutions paired with industrial batteries addresses CPO pain points and opens new commercial opportunities. ABL cross-selling is ramping, with double-socket commercial charger sales outside Germany exceeding €1 million per quarter within three quarters of acquisition integration.

Key Considerations

Wallbox’s Q2 marks a transition from defensive cost management to proactive growth capture, with backlog, product launches, and geographic focus all shifting toward opportunity. The company’s ability to execute on backlog and sustain cost discipline will determine the strength of the recovery as market conditions evolve.

Key Considerations:

  • Backlog Conversion Pace: Timely conversion of the €5M+ backlog into revenue is essential for margin and cash flow improvement.
  • Cost Structure Sustainability: Maintaining OPEX and cash cost discipline as sales investments are selectively ramped will test operational agility.
  • Product and Channel Differentiation: Early-mover advantage in bidirectional charging and energy services could drive higher-margin, recurring revenue streams.
  • Regional Policy and Demand Volatility: U.S. EV policy changes and European subsidy shifts present ongoing demand and pricing risk.

Risks

Wallbox faces significant external risks from U.S. regulatory changes, notably the expiration of the 30D tax credit and evolving emissions policies, which could dampen North American EV demand. Execution risk remains in converting backlog and scaling new products, while freight and tariff costs may pressure margins if demand spikes unpredictably. European growth is uneven by country, requiring ongoing resource reallocation and market vigilance.

Forward Outlook

For Q3 2025, Wallbox guided to:

  • Revenue between €38 million and €41 million
  • Gross margin of 37% to 39%
  • Adjusted EBITDA loss of €6 million to €4 million

For full-year 2025, management reiterated a focus on:

  • Operational break-even at the adjusted EBITDA level
  • Continued backlog build and conversion, especially in fast charging

Management highlighted European EV market recovery, North American partner traction, and backlog conversion as key drivers for a stronger second half. Ongoing cost discipline and selective sales investments are expected to underpin progress toward profitability.

Takeaways

Wallbox’s Q2 signals a shift from stabilization to growth capture, with backlog expansion and operational discipline setting up a more constructive second half. Execution on backlog, cost control, and new product scaling are the levers to watch as the company navigates a recovering European market and a volatile U.S. landscape.

  • Backlog Momentum: The €5M+ increase in backlog is a leading indicator for near-term revenue acceleration, especially as fast-charging demand returns.
  • Cost Reset Foundation: Sustained cost reductions provide flexibility for targeted growth investments without sacrificing the path to profitability.
  • Energy Ecosystem Positioning: Quasar 2 and VPP initiatives could unlock higher-margin, recurring revenue, differentiating Wallbox from commodity hardware peers.

Conclusion

Wallbox delivered a disciplined Q2, balancing cost control with renewed backlog growth and strategic product launches. The company’s trajectory now hinges on converting backlog and scaling energy services, with European recovery and U.S. policy shifts as key external variables.

Industry Read-Through

Wallbox’s backlog expansion and margin discipline reflect a broader EV charging market pivot from oversupply to targeted growth, especially in Europe where subsidy-driven demand is rebounding. Bidirectional charging and virtual power plant pilots signal a shift toward energy management and grid services, a trend likely to accelerate across the sector. U.S. regulatory risk remains a headwind for all EV infrastructure players, while inventory and cost resets are becoming a baseline for capital-efficient growth. Competitors and suppliers should expect intensified focus on product differentiation, channel integration, and recurring software revenue as hardware margins compress.
