Solar-glass margins and capacity prep: can Q1's 35% EBITDA hold into H2?
A quarter to watch capacity utilization ahead of the Dec '26 furnace-ramp—and whether Q1's stellar 35% standalone EBITDA margin holds as pricing pressures mount in solar glass.
The Setup: Margin Hold vs Capacity Timing
Borosil Renewables enters Q2 FY27 riding a dramatic margin expansion—standalone EBITDA of 35% in Q1, up from 27.9% a year ago—as solar-glass pricing normalised and the company bore down on cost efficiency. The Street's consensus target sits at ₹580 (JM Financial: ₹600 Buy; Kotak: ₹560 Neutral), a 51% premium to today's depressed ₹383.65, but execution risk looms: the flagship 600 TPD capacity expansion—originally due in December—has slipped to March 2027, shaving full-year utilization and pushing the revenue inflection to FY28. Watch whether Q2 sustains Q1's margin fireworks, or whether competitive solar-glass pricing and the utilization gap force a retrenchment.
~₹370–390 Cr
Q1 FY27 was ₹405.7 Cr (up 17.1% YoY); Q2 FY26 baseline ₹379 Cr. Expect mid-single-digit growth.
~32–35%
Q1 FY27 hit 35% (vs 27.9% YoY). Pricing normalisation and cost controls have lifted the floor, but watch for seasonal or competitive pressure.
~600 TPD baseline
Existing installed capacity. New furnaces pushed to Mar 2027, so no incremental throughput in Q2.
18% EBITDA margin target
Management aims for 18% EBITDA margin and ₹125–150 Cr capex for the year. On-plan if margins hold.
A strong Q2 would sustain Q1's margin momentum—30%+ standalone EBITDA with flat-to-modest revenue growth, showing that the 31% solar-glass margin from Q1 is durable, and that cost initiatives (furnace efficiency, raw-material yields) are structural wins, not a one-quarter bounce. A weak print would be margins compressing below 30%, signalling either competitive solar-glass pricing pressure or that some of Q1's margin beat was transient (favourable input costs, higher-margin product mix that couldn't repeat). Revenue misses south of ₹360 Cr would flag demand softness in the solar-sector order book.
On Track?
Borosil is tracking its trajectory: Q1 FY27 delivered ₹405.7 Cr revenue (17.1% YoY) and a consolidated swing from ₹203.5 Cr loss to ₹86.6 Cr PAT. Margins expanded sharply across both standalone (35% EBITDA) and consolidated lines. The company guided for an 18% EBITDA margin in FY27 and ₹125–150 Cr capex; Q1's 35% standalone easily clears that bar. The risk: the March 2027 slip on the 600 TPD expansion means FY27 benefits only modestly from new capacity (a few months of operation at best), pushing the full profit inflection to FY28. Guidance assumed Dec '26 commissioning; a shift to March is a 3-month headwind on the year-on-year growth, though the company has raised FY26–FY28 revenue expectations to ₹2,500+ Cr post-expansion.
What the Street Says
Since Last Quarter: The Filings Scan
1 · Capacity Expansion Slip (Sep 22, 2026)
The 600 TPD Bharuch expansion, originally planned for Dec 2026, now slips to Mar 2027—a 3-month delay. Original capex ₹1,100 Cr; this is the material headwind to FY27 revenue and margin inflection. No re-guidance has been issued, suggesting management sees the slip as manageable within FY27 guidance.
2 · Customs Fine (Oct 17, 2026)
Borosil received a redemption fine of ₹30 Cr + ₹30 L penalty (total ₹33.3 L) for incorrect customs classification. Non-material to Q2, but flag any broader compliance commentary on the call.
3 · Insider Trading Window Closure (Sep 25, 2026)
Trading window closed ahead of results. Routine, per SEBI rules; note it if there's material insider activity post-close.
4 · Warrant Conversions & Allotments (Jul–Aug 2026)
Ongoing warrant conversions (53.38 L shares in Aug, 12.5 L in Jul, 3.09 L in mid-Jul) adding ~69 L incremental shares. Dilution is factored into consensus EPS, but watch for any guidance on fully-diluted share count.
5 · Board Meeting Scheduled Oct 30, 2026
Q2 FY27 results expected on result day. The Oct 23 intimation confirmed a board meeting for unaudited results approval—on schedule.
Three Things to Watch on October 30
1. Can margins hold? The litmus test. 30%+ standalone EBITDA (vs 35% in Q1) signals durability; below 28% is a red flag that Q1's exceptional margin was transient or dependent on pricing benign conditions that have since shifted. 2. Capacity update. Management may re-guide on the Mar 2027 furnace commissioning—any further delays or revised capex outlook would reshape FY27–FY28 growth expectations. Listen for demand signals: is the delay tactical (deliberate hold pending solar-panel orders) or forced (supply-chain/project challenges)? 3. Consolidated margin & PAT.** Q1 swung to ₹86.6 Cr profit; watch whether Q2 sustains it or moderates as standalone profitability is offset by lower-margin legacy segments or higher depreciation from the capex ramp. A miss on PAT guidance could drag valuation even if EBITDA holds.
Borosil Renewables enters Q2 FY27 as a margin-expansion story—Q1's 35% EBITDA is exceptional and now the earnings bar to hold. The capacity expansion slip to March 2027 is a real headwind, shaving FY27 incremental revenue, but management has signalled confidence in full-year guidance and the long-term trajectory (₹2,500+ Cr revenue post-expansion). The Street sees ₹580 consensus value; getting there requires margin durability, on-time capacity commissioning, and credible FY28 pre-guidance. On October 30, watch the margin floor, the capacity update, and any restatement of FY27 PAT expectations—those will frame the next 12-month narrative.
