Borosil Renewables Limited issues fresh guidance

The presentation does not support the premise that both SG-3 and SG-4 were recently commissioned or operating at a disclosed utilization rate. SG-3 is shown as an existing 550 TPD furnace added in Q1 CY23, while SG-4 is part of the planned expansion alongside SG-5—not a commissioned line. Line-level capacity utilization is not disclosed. ^[1]

• SG-3: Existing 550 TPD Indian furnace, included in the company’s 1,000 TPD installed capacity as of Jul-25. ^[1]
• SG-4: Planned 300 TPD furnace, to be commissioned together with SG-5; the two new furnaces are targeted for commissioning by December 2026. ^[1]
• Utilization: No SG-3 or SG-4-specific utilization percentage, actual production volume, or ramp-up rate is reported in the presentation. Accordingly, utilization cannot be calculated from the disclosed data.

Alignment with the production target

The stated expansion is:

• Existing capacity: 1,000 TPD
• Increment from SG-4 and SG-5: 600 TPD
• Target combined capacity: 1,600 TPD, equivalent to approximately 10.5 GW of solar-glass capacity. ^[1]

Thus, the growth outlook is a capacity-addition target, not evidence that SG-3 and SG-4 are currently running at a particular utilization level. SG-3 is already embedded in the current 1,000 TPD base; SG-4 represents part of the future 600 TPD addition. The presentation’s disclosed target would require the planned furnaces to be commissioned and progressively ramped, but it does not provide the production-volume run rate needed to assess whether that target is already being achieved.

The company’s reconciliation is conditional rather than dependent on a full recovery in spot pricing: projected margin expansion is meant to come primarily from scale, operating leverage, and product mix, while the ADD notifications should improve the competitive floor against imports. The company has not disclosed a quantified increase in realization per mm, so the duty should not be interpreted as a one-for-one price uplift.

• What the ADD changes: The strategy presentation cites a 2 June 2026 customs notification imposing a 9.71% CVD on imports from Malaysia, while imports from China and Vietnam face higher ADD in the form of a reference price through December 2029. This should reduce the ability of low-priced imports to set the domestic benchmark, but it does not guarantee an equivalent increase in Borosil’s invoice realization. ^[2]
• Where the projected margin expansion comes from: Management’s stated plan is to increase capacity from 1,000 TPD to 1,600 TPD by April–June 2027, reach approximately Rs 2,500 Crores of turnover at full-year run rate, and achieve EBITDA-margin expansion through higher scale and efficiencies. ^[3]
• Why realization per mm remains the key uncertainty: Borosil offers multiple thicknesses, coatings, finishes and customized products, including 2 mm and value-added anti-reflective, anti-soiling and anti-glare offerings. A richer mix can support realization, but the presentation does not quantify the mix benefit or provide an indexed realization-per-mm bridge. ^[4]
• Current operating evidence: Consolidated EBITDA margin was 34.8% in Q1 FY27, up from 33.0% in Q4 FY26, but the reported financial data does not attribute that movement specifically to ADD or to a higher realization per mm. ^[5]

Analyst read: ADD provides downside protection by narrowing the import-price gap; it is not evidence of immediate pricing power. The projected margin expansion therefore rests on the combination of import normalization, fuller utilization of the enlarged furnace base, manufacturing efficiencies and value-added mix. If domestic prices remain capped despite ADD, the volume and cost-leverage assumptions would have to carry more of the margin bridge. The critical disclosure to monitor is the company’s actual realization per mm after the notifications and whether it rises without sacrificing volume.

Borosil Renewables is planning a 600 TPD addition, but the presentation contains an internal timeline inconsistency. The capacity-milestone slide says the two 300 TPD furnaces would be commissioned by December 2026 ^[1], while the growth-outlook slide places commissioning in April–June 2027 ^[3]. Therefore, the defensible timeline is late 2026 to Q1 FY28, with the latter date appearing on the main forward-outlook slide.

Peer comparison

• Borosil Renewables: Capacity would rise from 1,000 TPD to 1,600 TPD, a 600 TPD addition ^[1]. The presentation’s primary outlook points to April–June 2027 ^[3].
• Borosil Scientific: The presentation identifies it primarily with laboratory consumables, laboratory equipment, pharma primary packaging and process sciences; it provides no solar-glass capacity-addition plan for the company ^[6]. It is therefore not a directly comparable solar-glass peer on the cited evidence.
• Sejal Glass: No company-specific solar-glass capacity addition or commissioning date is reported in the cited materials. A direct timing comparison cannot be established.
• Industry benchmark: Domestic solar-glass capacity is projected to increase from 2,600 TPD currently to 7,900 TPD by March 2027, against stated demand of 11,000 TPD ^[2]. The industry-wide increase of 5,300 TPD is derived from those figures; Borosil Renewables’ 600 TPD addition would represent approximately 11.32% of that aggregate increase, although this is not a peer-by-peer comparison.

Implied market-share target

The presentation does not state an explicit sales market-share target. The implied capacity-based target is:

• Against stated demand: 1,600 TPD / 11,000 TPD = 14.55% of the stated solar-glass demand, versus 1,000 TPD / 11,000 TPD = 9.09% currently. This implies an increase of approximately 5.45 percentage points in capacity coverage of demand. The calculation uses Borosil Renewables’ 1,000 and 1,600 TPD capacities ^[1] and the presentation’s 11,000 TPD demand estimate ^[2].
• Against projected domestic capacity: 1,600 TPD / 7,900 TPD = 20.25% of projected domestic capacity by March 2027, derived from the same capacity figures ^[1] and the industry-capacity outlook ^[2].

The most relevant interpretation is therefore approximately 14.55% of the stated demand pool, not a formally announced market-share commitment. These are capacity-share proxies; actual sales share would depend on utilization, exports, imports and competitor commissioning.
