Stem, Inc. (STEM) How It Makes Money

Stem, Inc. primarily generates revenue by selling its AI-driven clean energy software, PowerTrack, which is often bundled with energy storage and solar monitoring hardware, creating a high-margin, recurring revenue model. This strategy centers on optimizing clean energy assets to maximize their economic value for customers, moving the company away from its historical, lower-margin focus on battery hardware resale.

Stem, Inc.'s Revenue Breakdown

The company's strategic pivot to a software-centric model is clearly visible in the Q3 2025 revenue mix. Total revenue for the third quarter of 2025 was $38.2 million, a 31% increase year-over-year. The vast majority now comes from its core, higher-margin offerings.

Here's the quick math: The Battery Hardware Resale segment contributed approximately $4.0 million to the Q3 2025 total. That leaves the high-growth, strategic Software and Edge Hardware/Services segment at about $34.2 million, or roughly 89.5% of the quarter's revenue. PowerTrack software revenue alone grew 11% year-over-year, and Edge Hardware grew a strong 18% year-over-year, confirming the strategic shift is defintely working.

Business Economics

The core of Stem, Inc.'s financial engine is the shift from transactional, low-margin hardware sales to a subscription-based, high-margin software-as-a-service (SaaS) model. This change fundamentally alters the company's cost structure and long-term financial stability.

• Pricing Strategy: The PowerTrack platform is sold via long-term contracts, generating Annual Recurring Revenue (ARR), which stood at $60.2 million as of Q3 2025, up 17% year-over-year.
• Margin Profile: The gross margins on the software products are substantially higher, reportedly in the 70% to 80% range, compared to the thinner margins on the bundled hardware. This mix shift is the main driver of overall margin expansion.
• Hardware as a Value-Add: The company now views the energy storage and solar monitoring hardware as a necessary component to enable the software, not the primary profit driver. This reduces working capital risk and balance sheet burden associated with large, low-margin inventory.
• Contracted Backlog: The contracted backlog stood at $22.2 million at the end of Q3 2025. This backlog, while down sequentially due to recognizing hardware revenue, represents future revenue visibility and is a key indicator of forward performance.

The name of the game is recurring revenue. If you want a deeper look at the balance sheet implications, check out Breaking Down Stem, Inc. (STEM) Financial Health: Key Insights for Investors.

Stem, Inc.'s Financial Performance

The Q3 2025 results, released in October 2025, show a clear inflection point, with the company achieving positive profitability on an adjusted basis for the second consecutive quarter.

• Revenue Guidance: Full-year 2025 revenue guidance was tightened to a range of $135 million to $160 million. This reflects management's increased confidence and reduced business volatility.
• Profitability Turnaround: Adjusted EBITDA (Earnings Before Interest, Taxes, Depreciation, and Amortization) was positive at $2.0 million in Q3 2025, a significant improvement from a loss of $(3.5) million in the prior year quarter.
• Gross Margin Improvement: GAAP Gross Margin was 35% in Q3 2025, up from 21% a year ago. The Non-GAAP Gross Margin reached 47%, demonstrating the immediate impact of the higher software revenue mix.
• Cash Flow: Operating Cash Flow turned positive at $11.4 million for the quarter. This is a monumental shift, tackling the old cash burn problem directly, and is a critical metric for a growth company.
• Net Loss: The Net Loss narrowed dramatically to $23.8 million in Q3 2025, a massive improvement from the $(148.3) million net loss in Q3 2024.

What this estimate hides is the potential for Q4 margin compression due to increased edge hardware deliveries, a timing issue that management is monitoring. Still, the trend toward positive Adjusted EBITDA and cash flow is a major step toward sustainable profitability.
