Synopsis: Foreign investors have sharply raised their holding in a leading solar glass manufacturer just as the company posted a strong June quarter, backed by pricing power and an ongoing capacity expansion.
Shareholding pattern data often gives early clues about how big money views a business. When foreign institutional investors raise their stake meaningfully in a single quarter, it usually reflects growing confidence in near-term earnings visibility. A recent stake addition in a solar glass player, alongside a robust June quarter show, has put the spotlight back on this stock.
Shares of Borosil Renewables Limited, with a market capitalization of Rs.8,150 Crore, closed at Rs.577.9 i.e. around 2.39% below its previous closing price of Rs.592.05. It trades at a P/E ratio of 19.89.
FII Stake Jumps Sharply in June Quarter
FIIs raised their holding in Borosil Renewables to 6.14% in the June 2026 quarter, up from 4.27% in March 2026, the highest level since at least September 2023. Promoter holding stayed largely steady near 58.78%, while public shareholding eased to 32.46% from 34.63%.
The stake addition comes alongside a period of policy tailwinds for domestic solar glass makers. The government extended countervailing duty on solar glass imports from Malaysia by five years in June 2026, adding to anti-dumping duties already in place on imports from China and Vietnam since December 2024. With domestic solar glass capacity still meeting only around a quarter of the country’s demand, local manufacturers continue to enjoy strong pricing support.
Strong Q1 FY27 Performance Backs the Confidence
The stake addition also comes on the back of a strong June 2026 quarter. Consolidated sales rose 53% year-on-year to ₹405.69 crore, while EBITDA came in at ₹142 crore, translating into a margin of 35%, up from 27.9% a year ago. This marks the fourth straight quarter of EBITDA margin staying above 33%.
The improvement was largely price-led. The average ex-factory selling price rose to ₹160.30 per square metre from ₹138.10 a year earlier, aided partly by a fuel surcharge introduced in March 2026 to offset rising energy costs following disruptions in West Asia. Sales volumes were also up 8% year-on-year, with the company running its plants at full capacity through the quarter.
Expansion and New Business Lines in Focus
The company is expanding its solar glass capacity by 600 tonnes per day at its existing location, a 60% jump over current capacity, with commissioning expected by March 2027. Management expects this to lift both sales and EBITDA proportionately once operational.
Beyond glass manufacturing, the company has entered the residential rooftop solar solutions space, offering complete systems comprising modules, inverters and batteries. This business is still at an early stage, with an internal revenue target of about ₹36 crore for the current financial year, though margins here are expected to be in single digits, unlike the 30-35% seen in the core glass business.
Government policies such as anti-dumping duties on imports and mandates requiring domestic sourcing of solar cells and modules continue to support local manufacturers, with management noting that domestic solar glass supply still falls well short of overall demand.
Eyes on Long-Term Growth Beyond FY27
Management has laid out plans to nearly double revenue from around ₹2,500 crore currently to ₹4,000 crore over the next three to four years, evaluating both additional solar glass furnaces and adjacent product lines to diversify beyond a single-product dependence.
Separately, the government’s upcoming ALMM 3 mandate, requiring domestic sourcing of ingots and wafers from mid-2028, is expected to further strengthen India’s solar manufacturing ecosystem and benefit component suppliers like Borosil Renewables over time.
Bottom Line
The sharp rise in FII holding aligns with a quarter of strong pricing power, healthy margins, and steady volume growth. With capacity expansion underway and a policy environment favouring domestic manufacturers, institutional interest appears rooted in fundamentals rather than sentiment. That said, near-term profitability includes a one-off tax adjustment, and investors should track how furnace maintenance and fuel-cost-linked pricing evolve in coming quarters.
