Expansion on track, margins reset lower—60% growth comes at cost of near-term pain
The verdict, the claims that held up, the sharpest analyst exchanges, and the risks — the earnings call, decoded from the transcript.
Hold
confidence 6/10
Grade B
Missed margin guidance (33%+ → 29.3%). H1 delivered 12.8% revenue growth but Q2 was flat QoQ. Capex plan on track; funding confirmed.
Optimistic

multi-year
Borosil is executing a credible 60% capacity expansion (600-TPD plant, ₹1,100 Cr capex, Q4 FY27 commissioning) with real demand tailwinds in solar glass. However, Q2 delivered EBITDA margin of 29.3% falls short of prior 33%+ guidance, management has reset expectations to 31%-32%, and Q2 revenue contracted 2.2% QoQ. Near-term (FY27-H1 FY28) is pressured by furnace maintenance downtime and cost inflation; long-term opportunity is genuine but execution risk and margin reset warrant a Hold pending new plant ramp.

Earnings quality
What changed since the last call
EBITDA margin guidance reset lower
DowngradeFrom 33%+ (Q1 call) to 31%-32% (Q2 call), floor 30%. Q2 delivered 29.3%. Clear step-down; management expects recovery but cautious.
Capex increased ₹150 Cr
UpgradeNew plant capex revised from ~₹950 Cr to ₹1,100 Cr. Exchange impact ~20%, additional cost redundancy for power failure. But full funding confirmed (internal + debt).
Furnace maintenance impact quantified
NewManagement disclosed 75-day shutdown for 2 existing furnaces in H1 FY28; estimated ₹15 Cr revenue loss but offset by new plant.
Rooftop business ₹100 Cr target upsized
UpgradeFrom implied ₹36 Cr (Q1 call) to ₹100 Cr in FY27 end. Early response 'extremely good'; distributors in 4 states, projects signed. But unproven at scale.
Cost inflation acknowledged but pass-through limited
DowngradeSoda ash +10%, imported limestone/dolomite +10% from freight/China tariffs. Pass-through to customers limited; gross margin erosion persists.
The Q&A
Analysts pressed hard on furnace downtime (Sanyam Dhoka: can 60% growth survive 75 days?), cost inflation (Pankaj Kumar: raw material cost pass-through?), and rooftop profitability (Adit: how sustainable?). Management held firm on capex plan and demand, but conceded margin pressure temporary; some evasion on rooftop unit economics and specific FY28 milestones. Pressure was medium; management articulate but occasionally speculative.
Production disruption revenue impact — Deepak Purswani, SVAN Investments
AnsweredEstimated ₹15 Cr revenue loss from 4.5% production dip. Capex revised up ₹150 Cr due to exchange (20%) and redundancy for power supply—fully funded internally + ₹300 Cr debt already arranged.
Realization and furnace timeline — Kaushal Sharma, Equinox Capital Ventures
AnsweredCurrently ₹155.9/mm, targeting ₹160/mm by Q3 FY27. Two furnaces to fire in February and March respectively; on track to deliver by end of FY27.
60% growth feasibility with furnace downtime — Sanyam Dhoka, Front Wave Research
PartialNew plant comes online end of Q4 FY27, offsetting old furnace downtime. New plant production 600 TPD will more than compensate; no net output loss expected.
Capex funding structure and debt — Saket Kapoor, Kapoor & Co.
Answered₹800 Cr from internal accruals, ₹300 Cr debt already committed (no further debt needed). Equity already raised via warrant/preferential issuance. Fully funded; no increase in debt post-commissioning.
Rooftop business scalability and profitability — Adit, AG Capital
PartialVery early stage; leveraging Borosil brand and distributor network. Early response 'extremely good' from customers. Margins will be low initially (trading model) but improve as operations scale. ₹100 Cr revenue target for FY27-end; full profitability and scale plan TBD by end of year.
Raw material cost and gross margin decline — Pankaj Kumar, Kotak Neo
AnsweredSoda ash prices up 10% but negotiated; dolomite/limestone imported at 10% higher cost due to China tariffs and freight. Limited pass-through model due to market pricing. Plan to increase domestic sourcing (currently 30-40%, target ~60%) and productivity gains to offset.
Capacity utilization and future capex — P. K. Kheruka (closing remarks)
AnsweredCompany well-positioned in solar glass due to skill and cost efficiency. For now, focus on commissioning the 600-TPD plant and achieving 1,600 TPD total capacity. Exploring other specialty glass options by end of year; no committed capex beyond the announced ₹1,100 Cr.
Warrant dilution and pending liabilities — Saket Kapoor (final question)
AnsweredAll warrants fully resolved. Promoters paid in full by February 2025. SEBI-compliant; no pending dilution. Equity issuance already accounted for.
Guidance
60% sales growth expected post 600-TPD plant commissioning Q4 FY27
MediumNew plant adds ~600 TPD; at current ex-factory price ₹155-160/mm, annualized revenue potential ~₹800-1,000 Cr. Overall 1,600 TPD capacity by FY28 can support 50-60% growth if demand absorbed and pricing held.
Rooftop business ₹100 Cr revenue target by end of FY27
LowVery early stage (4-state entry, projects signed). Extremely optimistic given typical solar rooftop project ramp; likely to be partially deferred to FY28.
EBITDA margin 31%-32% for FY27 and FY28; floor 30%
MediumReset down from 33%+ (prior call). Q2 delivered 29.3%. Management expects recovery with Oct production ramp and fuel surcharge stabilization by Q3.
Additional 2%-3% EBITDA margin leverage from new facility operational leverage (60% revenue increase on 600 TPD)
MediumDistribution of overheads over larger production base; achievable if volume absorbed and pricing maintained. But depends on market absorption and cost inflation trajectory.
₹1,100 Cr capex for 600-TPD expansion; ₹349 Cr spent to date (Sep 2026)
HighBuilding ~complete; machinery delivery underway; installation to start end of Q4. Full capex expected by March 2027. Commissioning targeted Q4 FY27.
No further capex beyond announced; company to explore new segment options by end of FY27
HighCEO stated no recklessness; will expand in profitable directions. Focus now on 600-TPD ramp and furnace maintenance.
Risks the call surfaced
Execution risk (new plant)
Medium₹1,100 Cr capex could see further cost escalation (exchange, material, labor). New plant may not fire on time (Q4 FY27) if machinery delivery or installation delayed. 600 TPD ramp-up pace unproven.
Margin compression
HighRaw material costs (soda ash +10%, imported dolomite/limestone +10%) rising. Limited pass-through to customers due to market pricing. EBITDA margin guided 31%-32% vs delivered 29.3%. If cost inflation persists, margins could stay below 30%.
Furnace downtime H1 FY28
MediumExisting furnaces (SG1, SG2, 7 years old) require 75-day rebuild each in H1 FY28. Management claims new plant will offset; but if new plant delay or ramp slower than expected, output gap opens.
Rooftop business execution
Medium₹100 Cr revenue target for rooftop solar business by end of FY27 is aspirational. Only 4 states launched; early-stage distributor model untested at scale. Margins likely low (trading model); profitability path unclear.
Customer concentration / demand absorption
LowWhile supply gap exists (62 GW demand vs 18 GW domestic supply), absorbing 600 TPD additional volume at current or higher prices is not guaranteed. Module manufacturers may vertically integrate glass in-house.
Management
Score 8/10. Clear and structured presentation; management fielded most questions directly. Provided specific numbers on capex, timeline, cost drivers. Some evasion on rooftop profitability specifics and speculative answers on 60% growth achievability. Strong track record on operational execution (furnace repair, production ramp in Oct). Capex tracking on schedule. Margin miss vs guidance (33%+ → 29.3%) and QoQ revenue decline are execution lags. H1 12.8% growth is solid but Q2 softness flags caution.
1 · Q3 FY27 (Oct–Dec 2026)
New furnaces (2x) fire in Feb-March; production ramp to record levels; margins recover to 30%+ target
2 · Q4 FY27 (Jan–Mar 2027)
600-TPD new plant commissioning expected; capex completion; revenue run-rate inflection
3 · H1 FY28 (Apr–Sep 2027)
Furnace 1 & 2 75-day maintenance shutdown; offset by new plant volume; growth remains 50-60%
Near-term (FY27-H1 FY28) is pressured by furnace maintenance downtime and cost inflation; long-term opportunity is genuine but execution risk and margin reset warrant a Hold pending new plant ramp.
