About Stem, Inc.
Stem, Inc. is a U.S.-listed company traded on the NYSE under the ticker STEM, headquartered in Houston, Texas, in the United States. Founded in 2009 and incorporated in Delaware, the company has built its identity around the energy transition, using software, services, and edge hardware to help customers develop, operate, and optimize solar and storage assets. Stem initially gained traction by applying data analytics and artificial intelligence to energy management, and over time it has evolved from a hardware-heavy model toward a more software-led platform with recurring service revenues and a stronger focus on asset optimization.
Today, the core commercial offering is organized around the PowerTrack suite, which unifies products and services for commercial and industrial solar, utility-scale solar, storage, and hybrid applications. Stem’s platform provides monitoring, forecasting, optimization, and operational control tools designed to improve the economic performance and reliability of distributed and utility energy portfolios. The company also offers lifecycle services and OEM-agnostic edge devices that connect solar and storage assets to its software applications in a unified view. This gives Stem a differentiated position in the clean-energy software niche, at the intersection of storage orchestration, analytics, and energy asset management.

From a competitive standpoint, Stem is still best viewed as a specialist rather than a broad-based energy company. Its value proposition is tied to software intelligence, grid flexibility, and the monetization of renewable and storage assets, and management has repeatedly emphasized a strategic pivot toward software-focused growth. Stem’s footprint is global, with operations and assets under management in more than 50 countries according to company disclosures, which makes it relevant for investors seeking exposure to electrification, renewable integration, and grid modernization themes.
A major recent theme has been strategic realignment. During 2024 and 2025, Stem reduced its reliance on what had historically been a key source of revenue, battery resales, while reorganizing product development, marketing, and internal processes around its software and services roadmap. In early 2026, the company reported full-year 2025 results and then first-quarter 2026 earnings, highlighting continued progress in software revenue, gross margin improvement, and a fourth consecutive quarter of positive adjusted EBITDA. Stem also strengthened its balance sheet through a convertible note exchange and new debt issuance, improving financial flexibility as it executes its software-centered strategy.
For investors, Stem represents a U.S. public clean-energy technology company with meaningful operating leverage potential, but also with execution risk typical of smaller-cap growth names. Its market position is anchored in the U.S. and in NYSE-listed exposure to AI-enabled energy optimization, making it a distinct way to play the long-term decarbonization and grid digitization trend.
