The company anticipates capitalizing on increasing demand for resilient, cost-effective, low-carbon energy infrastructure, supported by favorable long-term tailwinds and potential tax equity investments. Zeo also intends to pursue organic regional expansion in underpenetrated geographies, broaden its service offerings to include roofing and other home services, and engage in strategic bolt-on mergers and acquisitions.

Management Comments

• Zeo believes these non-GAAP measures of financial results provide useful information to management and investors regarding certain financial and business trends relating to Zeo's financial condition and results of operations.
• Management believes that an integrated installation business maximizes profitability, ensures efficient navigation of local regulatory processes and drives sustained customer satisfaction.

Industry Context

This acquisition positions Zeo Energy to address the accelerating demand for electricity driven by the electrification mega-trend and the significant power requirements of AI data centers. By acquiring Heliogen's LDES technology, Zeo can offer solutions for power quality, capacity, and long-duration energy needs, which are critical for mission-critical AI infrastructure. The move also aligns with broader industry trends of increasing utility prices, growing demand for grid resilience due to rising outages, and a shift in financing towards solar leases and Power Purchase Agreements (PPAs) amidst high interest rates. Furthermore, Zeo aims to capitalize on opportunities arising from recent residential solar bankruptcies, which have created a need for operations and maintenance (O&M) services for stranded assets.

Comparison to Industry Standards

• Zeo's U.S. residential solar market adoption (5%) materially lags other international markets, such as Australia (38%), Netherlands (24%), and Germany (12%), indicating significant room for domestic growth.
• Compared to industry peers (Complete Solaria, Sunrun, Sunnova, Enphase Energy), Zeo maintains a low Net Debt / Market Cap ratio of 0.1x, similar to Complete Solaria and Sunrun, but significantly lower than Sunnova (8.4x) and Enphase Energy (1.3x).
• Zeo differentiates itself with a vertically integrated sales and installation model and in-house financing, contrasting with competitors who may rely on large dealer networks or are financing agnostic.
