Blue Star Ltd Q4 FY2026 Concall Summary

Key Takeaways

• Summer arrived late, but Q4 revenue hit a record: Demand for room ACs picked up only toward the end of the quarter, yet the company still delivered its highest-ever quarterly revenue.
• Margin pressure is structural, not seasonal: Management expects unitary product margins to stay under pressure until 2030, even as the room AC market potentially doubles to 4–5 crore units.
• Data centre MEP is the growth engine: The ₹1,000 Cr business is expected to more than double to ₹3,000 Cr within 3 years, driven by manufacturing and data centre build-outs.
• International business is a CDM play with no near-term visibility: The company is making products for others, not building its own brand, but management calls it a "wrong time" to talk long term given trade deal uncertainties.
• What to watch next quarter: Whether the remaining 5% price increase passes through in May/June billings, how long the summer lasts, and any additional input cost spike if the Middle East war continues.

Summer Season & Room AC Demand

• Late onset, cautious optimism: Summer set in on April 13, roughly two weeks later than usual, so advertising and field marketing were not deployed in March. Secondary sales have since picked up and primary movement has commenced, but management needs another 2–3 weeks to assess how the season will pan out.
• Price increase phasing: Of the ~13% warranted price increase, only ~8% has been realized so far because primary sales are just beginning. The remaining 5% will be realized as May/June billings happen, varying by model.
• Consumer impact is a downgrade, not a deferral: A 13% price increase net of the 10% GST benefit means the consumer pays ~3% more. Management believes buyers will trade down (5-Star to 3-Star, or to a cheaper brand) rather than postpone purchase, unless war-driven petroleum and diesel price increases push inflation high enough to force consumers to stop spending altogether.
• Inventory is manageable, margins are the real problem: Current inventory stands at ~45 to 60 days and could be exhausted within 20 days if summer is active. Production was moderated when summer had not set in, so inventory management this year will be better. The issue this year will be about margins rather than inventory.
• Q1 FY27 industry growth could look strong optically: If summer is good, Q1 industry growth could be 25% to 30% over last year, comprising ~15% real growth plus ~10% from the price increase, against a weak prior-year summer.

B. Thiagarajan: "In one single sentence, we are happy that the summer season has set in, we are not celebrating like it was 2024 summer. We have still 2, 3 weeks to go to assess how it is going to pan out."

Margin Pressure & Cost Headwinds

• Unitary products margin under structural pressure: Management expects 8% to 8.5% margins for the year, with 8.5% to 9% possible only in a good summer. The pressure is not cyclical: margins will remain under pressure until 2030 as competition intensifies and manufacturing capacity expands across the industry.
• Input cost visibility is poor: Rising input costs and volatile exchange rates create margin headwinds. Management stated plainly that visibility is absent: "It is bad. You don't have any visibility at all, whether it is exchange rate or whether it is the commodities." An additional input cost increase is expected once the current quarter ends if the war does not end.
• Price increase pass-through is time-sensitive: The additional price increase came into effect in May. Passing it on depends on secondary demand and dealer buying. If not passed on now, it will be more difficult later because the increase will look like only 3% over last year, making further increases harder to justify.
• Segment 1 margins dipped on project mix: Q4 FY26 margin was 6.5% vs 7.6% in Q4 FY25, and FY26 was 7.4% vs 8.2% in FY25, due to a change in project mix within the segment. Management wants to maintain 7% to 7.5% going forward.
• Segment 2 margin improvement was partly timing: Q4 FY26 margin of 10.4% vs 8.4% in Q4 FY25 benefited from the delayed summer onset, which meant advertising and field marketing expenses were not incurred in March, combined with prudent pricing and cost optimization measures in place since April 2025.
• The 13% price increase covers known costs, not future shocks: Management confirmed the 13% increase covers desired margin levels, but it does not account for future cost increases such as plastic and petroleum-based input costs that could arise from war-related supply disruptions.

B. Thiagarajan: "The margins will be continuing to be under pressure until 2030. I am not seeing that it is 8% to 8.5% continuing as the market expands further."

Data Centre & Commercial AC Growth

• Data centre MEP is the standout growth driver: The ₹1,000 Cr data centre MEP business is likely to more than double to ₹3,000 Cr within 3 years. Blue Star provides electrical and mechanical accessories in these projects, not cooling equipment, which data centre providers buy separately.
• Cooling equipment gap being addressed: Blue Star does not have the complete range of data centre cooling equipment such as CDUs and fan wall units. It has few chillers but not the full range, and is discussing partnerships for technology, though nothing material has emerged yet.
• Commercial AC outlook at 8–10% growth: Growth will be driven predominantly by the manufacturing sector and data centres. Manufacturing projects, spanning semiconductors, EV batteries and solar cells, will grow tremendously over the next 3 to 5 years.
• Projects segment margins will not expand with data centre mix: Even as data centre revenue grows to ₹3,000 Cr of a projected ₹20,000 Cr total, blended project margins will not rise to 8–8.5% or higher because the segment also includes buildings and other verticals with different margin profiles.
• Order inflow rebounded in Q4: Bookings grew 35% in Q4, supported by strong equity momentum for buildings, data centres and factories, though full-year order inflow was lower by 10% vs FY25 because previous quarters were sluggish.

International Business: CDM Strategy in an Uncertain World

• Strategy is contract manufacturing only: Blue Star is not entering international markets with its own brand, not acquiring any brand, and not setting up joint ventures. It is making products for others as a CDM manufacturer.
• Near-term visibility is absent: Management called it a "wrong time to be talking about long term" for international business, with many trade deals on the verge of signing and huge uncertainties. The US HVAC market is stagnant or de-growing, and Europe has been slow and continues to be slow.
• US prospects tied to trade deal: Future prospects of the US business are highly dependent on the outcome of the India-US trade deal. The foray into the US is progressing well, and supplies to Europe have commenced.
• Growth is from a tiny base: Blue Star is a new entrant in these markets, so even 100 units represents growth. In about 3 years, depending on how the global economy pans out, management expects to begin growing that business significantly, though no specific revenue targets were provided.

B. Thiagarajan: "Blue Star is not entering with its own brand. Blue Star is not acquiring any brand from those markets. Blue Star is not setting up any joint ventures there. It is Blue Star making products for others as a CDM manufacturer. That is our strategy."

Other Businesses & Strategic Choices

• Commercial refrigeration had a bad year: FY26 was muted, dominated by the ice cream segment, with frozen food and QSR demand subdued throughout. The market is ~₹5,000 Cr vs the ₹35,000 Cr+ room AC market. FY27 outlook is wait-and-watch.
• Storage water coolers bucked the trend: Double-digit growth driven by strong demand from government and corporate sectors.
• MedTech slowed on regulatory uncertainty: The MedTech Solutions business slowed down due to unresolved uncertainties around the regulatory policy framework.
• No plans to enter white goods: Management was explicit that for the foreseeable future, the company will remain focused on air conditioning and refrigeration, with growth coming from geographical expansion and the high-growth India market.
• Market share ambition is measured: Blue Star is marching toward 15% market share from the current ~14.25%, but is not chasing market share at the expense of margins and cash flows.
• RAC capacity expansion decision in October: The Sri City factory is operating at 100% capacity of ~6.5 lakh units. Capacity can be expanded from 9 lakh to 12 lakh units by adding an assembly line, with the building already available. A decision will be taken in October.
