Sun Mobility Narrows Annual Loss As Revenue Surges 79% on EV Infrastructure Demand

Sun Mobility Private Limited, a prominent player in India’s electric vehicle (EV) energy infrastructure space, reported a significant narrowing of its annual loss for the fiscal year ended March 31, 2026, driven by a near-doubling of its top-line revenue.

The company, founded by EV pioneer Chetan Kumar Maini, saw its total revenue jump 79% to Rs 594.88 crore, up from Rs 331.71 crore in the previous fiscal year, according to filings with the Ministry of Corporate Affairs sourced through Tracxn. This growth comes as the automotive industry accelerates its transition toward electrification, particularly in the commercial fleet and two-wheeler segments where Sun Mobility’s core business operates.

Losses Shrink Amid Scaling

The Bengaluru-based firm reported a net loss of Rs 9.33 crore for FY2025-26, a sharp decline from the Rs 92.43 crore loss recorded the year prior. This improvement suggests the company is beginning to find economies of scale in its capital-intensive business model. Total expenditure for the year rose more modestly than revenue, reaching Rs 621.74 crore compared to Rs 430.74 crore in the previous period.

Business Model and Industry Context

Sun Mobility operates at the intersection of energy and transportation through three primary verticals. Instead of the traditional plug-in charging model, which can take hours, the company provides stations where EV drivers can swap a depleted battery for a fully charged one in minutes. This technology is critical for the automotive industry to solve range anxiety and minimize downtime for commercial drivers. The company produced and sold batteries and charging stations worth Rs 331.96 crore, with a significant portion of these sales directed toward its partner, Indofast Swap Energy.

Moving beyond just hardware, Sun Mobility’s MaaS model provides customers with a bundled package of vehicles and energy infrastructure, effectively lowering the upfront cost of EV adoption for fleet operators. This segment, along with engineering services, generated Rs 181.58 crore in revenue.

The Mobility-as-a-Service (MaaS) model operated by Sun Mobility functions as an integrated solution that transforms electric transportation into a subscription-like utility for its customers. This approach leverages the company's proprietary energy infrastructure platform to provide electric vehicle mobility directly to users, particularly commercial fleet operators who need to minimize the high upfront costs of transitioning to electric fleets.

The financial mechanics of the model are based on specific customer agreements, where the revenue is divided into two primary streams: a fixed monthly charge that provides a stable baseline for the service and a variable charge that is calculated based on the actual usage of the vehicles.

By bundling the vehicle, the battery, and the energy required to power them into a single offering, the company allows its clients to pay for mobility as an operational expense rather than a massive capital investment, with the provider handling the underlying complexities of battery-vehicle integration and energy management.

International expansion

While India remains its primary market, Sun Mobility is increasingly looking abroad. Export earnings reached Rs 130.58 crore during the year, nearly doubling from the previous year's Rs 75.37 crore. This international expansion is a strategic move to diversify revenue streams as global demand for interoperable EV battery standards grows. The majority of the exports revolved around services Sun Mobility offered to its Singapore-based holding company, Sun Mobility Pte. Ltd., thereby acting like a Global Capability Center (GCC) model, where Indian engineering talent is powering the international EV infrastructure of the parent brand.
