Sobhagya Mercantile Limited is fundamentally a platform for building infrastructure - not just as a contractor, but by owning the materials, the machines, and the expertise that construction demands. Incorporated in 1983 and listed on the Bombay Stock Exchange, the company was reshaped after the MKS Constro-Venture group took control, transforming it from a single-focus player into a diversified enterprise that now reaches from road-building and engineering design all the way back to the stone quarries and coal mines that feed its projects. The recurring approach is backward integration: whenever the business spots a reliable need in its own supply chain - aggregates for roads, coal for energy, steel for construction - it moves to supply that need itself, turning cost centres into standalone revenue engines. # Business segments Three engines at different stages - a construction-and-consultancy core that generates the bulk of activity, a materials business that feeds it from behind, and a cluster of resource bets being built for the future - each one designed to capture more of the value chain. ## 1. Infrastructure Construction: where the group builds its reputation **The company bids for and executes large government road and irrigation projects, earning fees under long-term contracts where the customer pays for both construction and the capital tied up during the build.** - **Paid to build, then paid to wait** - under the Hybrid Annuity Model (HAM), the government pays 40% of the project cost during construction and the remaining 60% as an annuity over the concession period, which gives the company a steady post-construction income stream alongside the upfront construction margin. - **Roads are the backbone** - the company has completed multiple road projects in Chandrapur District, Maharashtra, including a 73.5-kilometre stretch under the NAG 182 project and a roughly 95-kilometre package under NAG 176, establishing a track record that supports its aggressive bidding strategy for new government tenders. - **Irrigation opens a second front** - in mid-2026, SML entered a joint venture as a 40% partner to build the Adyal Lift Irrigation Scheme for Vidarbha Irrigation Development Corporation, a Rs. 260-crore contract with a 33-month timeline, signalling a deliberate push beyond roads into water infrastructure. - **Projects run through promoter-group SPVs** - the Board has identified HAM road projects awarded to special-purpose vehicles controlled by the promoter group as an attractive investment channel, meaning SML can participate in projects originated and structured by its own ecosystem rather than competing blind. ## 2. Infrastructure Engineering: the consultancy that feeds the pipeline **The company designs and supervises infrastructure projects from concept to completion, earning fees for the intellectual work that precedes and oversees the physical construction.** - **End-to-end project brain** - the division delivers everything from conceptual design and Detailed Project Reports (DPRs) through to construction supervision and Project Management Consultancy (PMC), guiding clients across the entire lifecycle of an infrastructure asset. - **A separate revenue stream from the same client base** - engineering consultancy is reported as a distinct segment alongside construction, meaning the company gets paid twice on many projects: once for designing them and again for building them. - **Eyeing specialised niches** - the company sees growth in expanding into geotechnical, structural, and environmental engineering, which would move it up the value chain into higher-margin advisory work that requires credentials fewer competitors hold. ## 3. Metal Sale: the quarry that supplies its own projects **The company crushes and sells stone aggregates - the literal building blocks of roads and concrete - through its own stone-crushing unit, turning a raw-material cost into a revenue line.** - **Aggregates for its own roads and for others** - the segment produces high-quality crushed stone and sells it to infrastructure projects, which means SML can supply its own construction sites while also serving external customers. - **A standalone business, not just a cost centre** - this is one of the company's two reportable segments, with its own plant and machinery including crushers, conveyor belts, weigh bridges, and rollers, and its own cost structure covering drilling, blasting, royalty payments, and transportation. - **Backward integration in its simplest form** - rather than buying aggregates from third parties for its road contracts, the company owns the crushing unit that produces them, capturing the margin a supplier would otherwise take. ## 4. Mining: the resource bets being built for tomorrow **The company is developing two mining assets - a coal block and a critical-minerals venture - that will supply raw materials to energy and industrial customers once operational.** - **Critical minerals through a new subsidiary** - in April 2026, the company incorporated Vadakhol Asoli Mining Private Limited (60% owned by SML) to explore and mine nickel, chromium, cobalt, and associated minerals in Maharashtra. - **From extraction to sale** - the subsidiary's mandate covers the full chain: geological surveys, land acquisition, drilling, excavation, beneficiation, processing, refining, and ultimately the sale of minerals and value-added products like ferro alloys, making it a vertically integrated mining play rather than a pure extraction licence. ## 5. Steel Manufacturing: the forward-integration bet on construction-grade steel **The company is setting up an integrated steel plant in Gadchiroli, Maharashtra, that will produce sponge iron, billets, and rolled products - feeding its own construction needs and the open market.** - **Mega Project status secured** - the Government of Maharashtra conferred the 'Mega Project' designation on the proposed plant in January 2025, which typically brings with it a package of fiscal incentives and streamlined approvals. - **A full production chain under one roof** - the plant is designed to house a sponge-iron unit (1,000 tonnes per day), an induction furnace (1,500 TPD), a rolling mill for long and flat products (1,500 TPD), and a 32-megawatt waste-heat-recovery power plant, with a proposed investment of roughly Rs. 838 crore across 150 acres of industrial land. - **Forward integration to cut procurement costs** - the steel plant is explicitly described as a move to reduce reliance on external steel suppliers, meaning the construction division will eventually source its steel internally, capturing another layer of margin. # Group structure and partners **The company operates within a tight promoter ecosystem - projects, funding, and joint ventures flow through entities controlled by the same group, creating an integrated deal pipeline that standalone competitors cannot easily replicate.** - **No listed subsidiaries, but a growing web** - as of March 2025, SML had no subsidiaries, but it maintains extensive related-party relationships with promoter-group entities including MKS Constro-Venture Private Limited, B.K. Buildcon, R.B. Infra, and several others. - **The promoter group originates the deals** - the Board has explicitly approved investing in HAM road projects held through promoter-group SPVs, and the company has proposed related-party transactions with MKS Constro-Venture of up to Rs. 375 crore for FY 2026-27, covering both the sale of goods and services and the advancing of loans. - **Joint ventures extend the reach** - the Adyal Lift Irrigation Scheme is being executed through a 40:60 joint venture with S. S. Fabricators & Manufacturers, a structure that shares risk while bringing SML into a new infrastructure vertical.
