Capstone Energy+ is a high-risk microgrid turnaround with improving margins and powerful data-center optionality, but refinancing and contract execution determine whether upside outweighs dilution risk.
Overview
Capstone Energy+ develops and services customized microgrid and behind-the-meter systems using oil-free microturbines that run on natural gas, biogas, flare gas, propane, and hydrogen blends. Its three segments are Product and Accessories, Parts and Service, and Rentals/EaaS. The United States generated $70.13 million of FY2026’s $106.00 million revenue, while an 89-country distributor network provides international reach. The investment case combines a niche market position—over 50% to 60% microturbine share—with structural demand for resilient power and AI data-center capacity. **Q1 FY2027 showed operating leverage:** revenue fell 10.58% to $24.923 million, but gross profit rose 15.81% to $8.760 million, gross margin expanded 801 bps to 35.15%, operating income reached $1.000 million, and operating cash flow turned positive at $5.410 million. The valuation is moderate at 2.67x to 2.80x EV/revenue versus Bloom Energy’s 19.3x, although leverage and dilution matter. Near-term catalysts are refinancing the $25.3 million Exit Notes by December 7, 2026 and converting the data-center pipeline into contracts. The stock closed at $5.98 and trades below key moving averages.
