Flux Power (FLUX) Q4 2025: Gross Margin Jumps to 34.5% as Software-Driven Model Gains Traction
Flux Power’s Q4 saw a decisive shift toward higher-margin, software-integrated battery solutions, with gross margin climbing to 34.5% on improved product mix and operational discipline. Management’s focus on recurring software revenue, cost controls, and solution selling is reshaping the business model, but persistent tariff headwinds and cautious customer spending temper near-term optimism. Momentum in quoting activity and a $9 million backlog position the company for a stronger second half, provided execution on software attach and cost initiatives continues.
Summary
- Margin Expansion Signals Model Shift: Higher-margin product mix and operational savings drove significant gross margin improvement.
- Software Integration Accelerates: Sky EMS platform is moving from beta to commercial rollout, underpinning recurring revenue ambitions.
- Order Pipeline Rebounds: Increased quoting activity and a $9 million backlog set the stage for a stronger second half.
Business Overview
Flux Power designs, manufactures, and sells advanced lithium-ion battery packs and energy management solutions for industrial applications, primarily targeting material handling and ground support equipment (GSE) markets. The company generates revenue from battery hardware sales and is now layering in software, notably its Sky EMS (Energy Management System), to create integrated, intelligent fleet solutions. Key segments include material handling (e.g., forklift batteries) and GSE (airport ground vehicle power), with a growing focus on recurring software and telemetry revenue streams.
Performance Analysis
Q4 revenue reached $16.7 million, reflecting a robust increase from the prior year, with full-year sales up as well, driven by higher volumes in both core markets. The GSE segment benefited from higher average selling prices, while material handling saw a marginal offset from slightly lower pricing. Gross margin rose sharply to 34.5% for the quarter, up from 26.8% a year ago, propelled by cost-saving initiatives, improved product mix, and lower warranty expense.
Operating expenses increased, largely due to $2.9 million in one-time costs tied to a multi-year financial statement restatement. Excluding these, non-GAAP net loss narrowed substantially, and Q4 adjusted EBITDA turned positive at $600,000, a marked turnaround from the prior year’s loss. Cash on hand improved to $1.3 million, reflecting better working capital discipline.
- Product Mix Drives Margin: Sales of redesigned, higher-margin batteries and lower warranty expenses were key contributors.
- Cost Actions Materialize: Headcount reductions and vendor renegotiations helped offset tariff pressures.
- Software Attach Emerging: Initial Sky EMS sales contributed to both hardware and software revenue, supporting the shift to solutions-based selling.
Despite improved profitability metrics, the company remains below breakeven but is on a clear path toward sustainable positive EBITDA, contingent on continued execution.

Strategic Positioning
1. Integrated Solutions and Recurring Revenue
Flux Power’s transition from pure hardware to integrated solutions is accelerating, with the Sky EMS platform now being packaged alongside battery sales. This “intelligent battery” approach aims to embed telemetry and software into every unit, creating opportunities for recurring software revenue and post-sale upsell across an installed base of over 28,000 packs.
2. Operational Discipline and Cost Structure Realignment
Management executed a 15% workforce reduction (excluding sales/marketing) and renegotiated supplier contracts, both domestically and in China, to counteract tariff and inflation pressures. Additional product engineering efforts are underway to further reduce bill of materials costs, with the goal of sustaining margin gains.
3. Solution Selling and Customer Engagement
The sales organization has shifted to a “solution selling” model, engaging directly with end-users and OEMs to tailor offerings and maximize value. This approach has already yielded sizable new orders, including a $2 million+ GSE battery contract and a $1.2 million Sky EMS-enabled package, validating the strategy’s traction.
4. Market Expansion and Pipeline Visibility
Flux Power is leveraging its U.S. base to pursue growth in North and Central America, targeting both new verticals and geographies. Quoting activity has increased significantly, and the $9 million quarter-end backlog provides improved visibility, though conversion to revenue will lag by several quarters.
Key Considerations
This quarter marks a pivotal phase in Flux Power’s evolution, as management’s efforts to embed software and drive operational efficiency begin to reshape both the financial profile and the strategic narrative.
Key Considerations:
- Margin Expansion Sustainability: Cost actions and higher-margin product mix delivered results, but sustaining 30%+ gross margin will require continued supply chain management and product redesign.
- Software Monetization Pathway: Sky EMS attach rate and upsell to the existing installed base are critical for recurring revenue growth, with early customer feedback positive but commercial ramp still nascent.
- Tariff and Macro Uncertainty: Customer capital expenditure hesitancy, especially in material handling, remains a near-term headwind, as does the risk of further tariff escalation.
- Execution on Backlog: The $9 million backlog and increased quoting must translate into revenue to support the path to sustained profitability.
Risks
Persistent tariff exposure and macroeconomic caution among customers present ongoing risks, particularly as capital-intensive buyers in material handling and GSE markets defer purchases. The company’s reliance on successful software rollout and attach rates introduces execution risk, while one-time costs and the recent restatement highlight the importance of continued financial discipline and transparency. Failure to convert pipeline activity into revenue could stall the path to profitability.
Forward Outlook
For the first fiscal quarter, management noted:
- Some customer slowdown and pause in orders, especially in material handling, due to tariff and macro uncertainty.
- Significant increase in quoting activity, signaling stronger demand for the second fiscal quarter (calendar Q4 2025).
For full-year 2026, management did not provide formal guidance but emphasized:
- Continued focus on profitable growth and gross margin expansion.
- Acceleration of Sky EMS rollout and recurring revenue streams.
Management cautioned that tariff and macro headwinds will persist in the near term, but sees “increasing optimism for the later part of our fiscal year” as quoting activity converts to orders and solution selling gains traction.
Takeaways
- Margin Structure Reset: Cost actions and higher-margin products have reset the baseline, but margin durability will depend on further execution and market conditions.
- Software Upside Emerges: Sky EMS integration is early but promising, with a large installed base offering substantial upsell potential if attach and conversion rates accelerate.
- Pipeline Conversion Is Critical: A $9 million backlog and rising quoting activity must translate into revenue to sustain momentum and achieve breakeven.
Conclusion
Flux Power’s Q4 marks a turning point, with gross margin gains and software integration validating the strategic pivot toward solutions-based, recurring revenue. Execution on backlog and software attach will determine whether these early gains translate into sustainable profitability and market share expansion in fiscal 2026.
