Business Overview
Stem is a global provider of artificial intelligence-enabled clean energy software and services, specializing in optimizing solar and energy storage assets. The company generates revenue primarily through software subscriptions, edge hardware sales, professional services, and battery hardware resale. Its core business segments include PowerTrack software, storage asset management, and legacy hardware sales, with a strategic pivot towards recurring software and services revenue.
Performance Analysis
In the fourth quarter of 2024, Stem reported a significant revenue decline of 67% year-over-year to $55.8 million, reflecting a sharp reduction in battery hardware sales as the company transitions to a software-first strategy. Despite this drop, software revenue grew by 6% year-over-year, driven largely by PowerTrack’s expanding footprint. Non-GAAP gross margin improved to 36%, up from 13% in the prior-year quarter, illustrating the higher margin profile of software and services compared to hardware.
Adjusted EBITDA remained positive at $4.2 million, slightly below the prior-year quarter, as lower gross profit dollars from hardware sales weighed on profitability. Contracted backlog decreased 25% sequentially to $1.17 billion due to a conservative repricing of OEM hardware and elimination of delayed projects. Meanwhile, contracted storage assets under management (AUM) remained stable at 5.6 gigawatt hours, and solar monitoring AUM grew 5% sequentially to 29.9 gigawatts, underscoring steady demand for software-driven asset optimization.
- Hardware Revenue Contraction: Legacy battery hardware sales declined sharply, reflecting strategic deprioritization and market challenges.
- Software Revenue Expansion: PowerTrack’s adoption by major solar asset owners and international clients fueled recurring revenue growth.
- Backlog Recalibration: Conservative backlog adjustments improved visibility but reduced near-term revenue expectations from hardware projects.
Overall, Stem’s financial performance highlights the tension between legacy hardware declines and emerging software growth. The company’s improved gross margins and stable adjusted EBITDA signal progress in its transformation, albeit amid ongoing operational and market challenges.

Strategic Positioning
1. Software-Centric Growth with PowerTrack
Stem is doubling down on PowerTrack, its AI-enabled solar monitoring and optimization platform, which commands high growth margins of 70 to 80 percent. The software’s adoption by 13 of the top 16 U.S. commercial solar asset owners and new international contracts, such as the 484 megawatt deal in Hungary, underscore its strategic importance. PowerTrack’s relatively short sales cycle and scalable recurring revenue model position it as the cornerstone for sustainable growth.
2. Operational Cost Reduction and Efficiency
The company targets over 20 percent operational cost savings in 2025 beyond prior reductions, focusing on eliminating inefficiencies, streamlining corporate structure, and empowering management accountability. This initiative aims to improve adjusted EBITDA and cash flow, critical for Stem’s path to profitability amid ongoing revenue headwinds from hardware.
3. Revamped Software Development and AI Integration
Stem plans to overhaul its software development processes, refine product roadmaps, and accelerate AI incorporation both in development and product features. These efforts intend to enhance product competitiveness and customer value without disrupting existing client operations, aligning with the company’s software-first vision.
4. Financial Transparency Through New Metrics
Stem introduced updated definitions for backlog, contracted annual recurring revenue (CARR), and storage operating AUM to better reflect the evolving business model. Backlog now includes only fully executed purchase orders for hardware and non-recurring services, while CARR captures recurring software and service contracts. This segmentation improves visibility into revenue streams and growth drivers.
5. Hardware Business as Opportunistic and Declining
Battery hardware resale is expected to continue declining, with 2025 guidance capping this segment at $35 million. Stem views hardware sales as opportunistic, focusing on deals that complement software and services revenue while maintaining modest margins. This shift aligns with the broader industry move away from capital-intensive hardware toward scalable software solutions.
