Sunrise Batteries portfolio and diversification
Sunrise Batteries Ltd is a ₹850 crore lead-acid battery maker. Its product mix is: automotive replacement batteries, 60% of revenue, market growth 4%, relative market share 1.3; industrial UPS batteries, 25%, growth 9%, relative share 0.7; and two-wheeler OEM batteries, 15%, growth 14%, relative share 0.5. EBITDA margin is 11%, debt is low, and it holds ₹120 crore cash. The board sees lithium-ion as both a threat and an opportunity, but the firm has no cell-manufacturing capability. A consultant proposes either (i) a ₹100 crore joint venture to assemble lithium-ion battery packs for buses and stationary storage, using Sunrise’s distribution and service network, or (ii) an unrelated investment in commercial real estate to diversify cash flows. The promoter favours real estate because it is familiar and less technical. The CEO wants a strategy that protects the core while creating a second growth engine.
1. Classify the three businesses on the BCG matrix using the given growth and relative-share data, and explain the cash-flow implication for corporate strategy.

Classification
- Automotive replacement: growth 4% is low and relative share 1.3 is above 1.0, so it is a cash cow. It should generate cash, protect distribution and brand, and avoid heavy new capex unless it defends share.
- Industrial UPS: growth 9% is moderate-to-high and relative share 0.7 is below 1.0, so it is a question mark. It consumes cash if Sunrise tries to build share; the choice is selective investment, partnering, or a niche focus.
- Two-wheeler OEM: growth 14% is high and relative share 0.5 is below 1.0, so it is also a question mark, but with a weaker position and likely OEM price pressure. It is a candidate for a focused niche, contract manufacturing, or exit as electrification changes the powertrain mix.
The cash cow funds the question marks. The strategic error would be to let the cash cow stagnate while spreading cash across too many weak-share segments, or to divert the ₹120 crore into an unrelated business before the core is protected. The portfolio logic supports a disciplined build in one adjacent battery opportunity, not a broad diversification. The two-wheeler OEM business should be retained only if it provides scale, learning, or a route into EV customers; otherwise it is a cash trap.
2. Evaluate the two diversification proposals using the tests of corporate strategy - suitability, acceptability, and feasibility - and recommend one.

Lithium-ion pack JV
- Suitability: high. Pack assembly uses Sunrise’s battery distribution, service network, customer relationships, and quality systems. It is an adjacent step in the value chain, not a leap into an unrelated industry. It addresses the EV/storage threat and creates a second growth engine.
- Acceptability: moderate. ₹100 crore is within the ₹120 crore cash pile but would consume most of it; a JV structure shares capital and technology risk. Returns may be delayed, and the promoter may resist dilution of control.
- Feasibility: workable but capability-constrained. Sunrise lacks cell manufacturing, but pack assembly needs BMS integration, thermal engineering, and cell sourcing rather than cell fabrication. The JV partner must supply technology and qualification; Sunrise must hire engineering talent and secure cell supply contracts.
Commercial real estate
- Suitability: low. It does not use Sunrise’s battery capabilities and creates no learning or customer synergy. It is a financial diversification, not a corporate strategy.
- Acceptability: superficially attractive because it is familiar to the promoter, but it exposes the firm to a new cyclical sector and may signal that the core has no growth story.
- Feasibility: financially feasible but strategically distracting. It would consume cash and management attention without building a defensible position.
Recommend the lithium-ion pack JV, staged: commit ₹40 crore initially for a pilot line and technology transfer, with further tranches tied to customer contracts, safety certification, and gross-margin milestones. Keep the real estate proposal out unless the JV fails and the firm has genuinely surplus cash after protecting the cash cow.
