1 — At a Glance
Blue Star sells cooling. India, in the June quarter of 2026, declined to get hot on schedule.
Revenue for the quarter came in at ₹3,378 Cr, up 13.3% from ₹2,982 Cr. Operating profit went the other way — ₹175 Cr against ₹199 Cr, an operating margin of 5% versus 7%. Net profit was ₹102.5 Cr against ₹121 Cr. Profit before tax and exceptional items fell 23.7% to ₹125.6 Cr, per the company’s own investor update.
Management’s description of the quarter, on the August call, was “challenging,” and they listed the ingredients: “unprecedented escalation in commodity prices, depreciation of rupee, delayed onset of summer season and a huge inventory pile up of room ACs in the trade.” The Unitary Products segment — room ACs, deep freezers, water coolers — grew revenue 12.8% to ₹1,689 Cr while its EBIT margin went from 5.8% to 2.9%. Management sought to pass on about 13% of cost inflation and passed on 5%.
Meanwhile the projects half of the house had a fine time. Electro-Mechanical Projects revenue rose 15.1% to ₹1,625 Cr, order inflow rose 24% to ₹2,435 Cr, and roughly ₹1,500 Cr of that came from data centres alone. The carry-forward order book stands at ₹7,764 Cr, up 13.5% year on year.
An 83-year-old air conditioning company now has a quarter where the servers ordered more cooling than the households did. The rest of this entry works through what each half contributed.
2 — Introduction
Blue Star was established in 1943 by the late Mohan T Advani and listed on the Bombay Stock Exchange in 1969. It manufactures air purifiers, air coolers, water purifiers, cold storage and speciality products, offers turnkey solutions in MEP — Mechanical, Electrical, Plumbing and Fire-fighting — projects, and per its filings is the largest after-sales service provider for air conditioning and commercial refrigeration products in the country, maintaining roughly two million tonnes of installed equipment.
Seven manufacturing plants sit across Dadra, Wada, Ahmedabad, two facilities in Himachal Pradesh, and Sri City, the last of which began commercial production in 2023 and carries AC capacity of 10.50 lakh units. CARE Ratings notes the Sri City plant now makes heat exchangers and sheet metal parts in-house, and that over 40% of RAC sales are concentrated in South India. Distribution runs through 4,000-plus channel partners, plus Amazon, Flipkart, direct-seller and dropship models. Virat Kohli has been the brand ambassador for Room ACs and Air Coolers since 2019.
The recent calendar has been busy. In January 2026 the company reported unauthorised access to product installation data, with a cybersecurity investigation ongoing. Sam Balsara retired from the board on January 31, M S Unnikrishnan joined as Independent Director on January 29, Executive Director Venkata Rao Ponnada resigned effective January 15 and was relieved on February 28, and Independent Director Arvind Singhal resigned effective May 30, 2026. A postal ballot on March 31, 2026 re-appointed B Thiagarajan as Managing Director through May 24, 2027 and confirmed Mohit Sud as Executive Director from April 1, 2026.
In July 2026, an ICC arbitrator dismissed WJT’s ₹461.74 crore claim against the company, with interest and costs pending. CARE reaffirmed its long-term rating at AA+; Stable on July 7, 2026. Then on August 14, 2026, Blue Star E&E signed a business transfer agreement to sell its MedTech division to Cyrix for up to ₹40 crore.

3 — Business Model: WTF Do They Even Do?
Three segments, wildly different temperaments, one balance sheet.
Electro-Mechanical Projects and Commercial Air Conditioning was 54.5% of FY26 revenue. Central air-conditioning projects, electrical contracting, packaged and ducted systems, VRF units, scroll, screw, centrifugal and data-centre chillers, plus turnkey MEP and firefighting for buildings, factories, data centres, metro rail and substations. This is the business of promising a hospital that its operating theatre will be 21°C in 2028 and then, some years later, making that true. Clients include Nippon, Ola Electric Mobility, JCB India, Salcomp, LuLu Group, K Raheja Corp, Embassy Group, Wells Fargo, Oberoi Realty and Yashoda Hospitals.
Unitary Products was 43.0% of FY26 revenue: fixed-speed splits, inverter ACs, window ACs, deep freezers, storage water coolers, bottled water dispensers, visi coolers, cold rooms, supermarket refrigeration, kitchen refrigeration, healthcare refrigeration. Room AC market share was ~14.25% by value and ~11.25% by volume at Q4 FY26, against an FY26 Indian air-conditioning market the company sizes at ₹35,500 Cr, of which room ACs are ₹30,000 Cr. Note the gap between the value share and the volume share: Blue Star’s boxes carry a higher average ticket than the market’s. Note also that on the August call management said the fix is “the lowest cost entry-level products… 90% has to be that.”
Professional Electronics & Industrial Systems was 2.5% of FY26 revenue, run through wholly owned Blue Star Engineering & Electronics — MedTech Solutions, Data Security Solutions, Industrial Solutions, including refurbishing medical diagnostic equipment. It is the segment that most reliably requires a footnote, and as of August 14 the MedTech part of it is being sold.
R&D ran ₹147.56
