Solar Industries delivered another high-growth quarter as defence and international explosives expanded the earnings base. With H1 revenue already above ₹7,100 crore and management now expecting to surpass FY27 guidance, the debate shifts from growth visibility to whether execution and cash returns can justify a valuation near 90x trailing earnings.

Solar Industries Q2 FY27: Growth Remains Exceptional, but Expectations Are Higher

Solar Industries India reported consolidated Q2 FY27 net sales of ₹3,519 crore for the quarter ended September 30, 2026, up 69% YoY. EBITDA increased 75% to ₹1,021 crore, implying a 29.0% margin, while PAT rose 80% to ₹650 crore. H1 FY27 revenue reached ₹7,187 crore and PAT ₹1,316 crore, both significantly ahead of the year-ago period.

The numbers seem to suggest that the company is no longer dependent on its traditional domestic industrial-explosives franchise. Defence contributed about 29% of Q2 sales and international explosives 43%, while domestic explosives accounted for 27%. The mix shift toward defence and overseas operations is structurally changing both the growth rate and profitability of the company.

The key investment question, however, has also changed. Solar Industries already trades at a premium valuation and carries an order book above ₹20,000 crore. Investors will watch if the company can convert that backlog into revenue, sustain high-20s EBITDA margins and generate adequate returns on the large capex programme now underway.

Q2 Revenue and Margins: Profit Growth Continues to Outpace Sales

The quality of Q2 growth is visible in the gap between revenue and EBITDA. Net sales increased 69% YoY, while EBITDA rose 75% to ₹1,021 crore. EBITDA margin expanded to roughly 29.0% from about 28.0% in the year-ago quarter.

Margin resilience is key because Solar Industries is operating through a period of rapid scale-up. Defence manufacturing typically carries higher value addition than conventional bulk explosives, and international operations are also becoming a larger contributor. As these businesses expand, mix is becoming as important as volume.

Sequentially, revenue was modestly below the ₹3,668 crore reported in Q1 FY27, but EBITDA margin improved. That suggests the growth story is not simply being driven by higher throughput. The composition of revenue is helping protect profitability even as depreciation and finance costs rise with the investment cycle.

For H1 FY27, EBITDA stood at ₹2,045 crore on sales of ₹7,187 crore, translating into a margin of 28.45%. This provides a stronger base for the second half than the company had at the start of the year.

Defence Is Becoming the Core Earnings Driver

The biggest structural change in Solar Industries is the scale of its defence business.

Defence represented about 29% of Q2 FY27 sales and grew 98% YoY. In H1 FY27, defence sales were up 109% YoY. The company's defence order book stood at ₹17,568 crore at the end of September, accounting for nearly 87% of the total disclosed order book of ₹20,178 crore.

The defence portfolio now spans products such as Pinaka ammunition, guided munitions, 155 mm ammunition, loitering munitions, counter-drone systems and other high-energy materials. These programmes typically involve qualification, capacity creation and multi-year delivery schedules, which create longer revenue visibility than the more cyclical industrial-explosives business.

The order book is therefore a powerful growth asset. But it also concentrates expectations around execution. Delays in defence qualification, customer acceptance or production ramp-up can shift revenue between quarters or years. The larger the defence contribution becomes, the more important milestone execution becomes to the earnings model.

International Explosives Adds a Second Structural Growth Engine

International explosives contributed roughly 43% of Q2 sales, making it the largest customer segment in the quarter. The diversification reduces dependence on Indian mining and infrastructure demand while giving Solar Industries access to a larger global explosives market.

The company has spent several years building manufacturing and distribution capabilities across international geographies. The Q2 mix suggests those investments are now contributing at scale.

International expansion can also support margins if utilisation rises across established overseas facilities. At the same time, the strategy introduces currency, regulatory and integration risks that are less relevant in the domestic business.

Solar Industries is also preparing for a much larger international footprint through its proposed acquisition of Omnia's explosives business. The transaction is strategically significant but will increase leverage and integration complexity once completed. That makes the current balance-sheet position particularly important.

Order Book Remains Strong Even After Heavy Execution

Solar Industries ended the period with a total order book of ₹20,178 crore, comprising ₹17,568 crore of defence orders and ₹2,610 crore linked to Coal India and Singareni Collieries.

The order book declined from more than ₹21,350 crore at the end of Q1 FY27 even though H1 revenue grew 70%. That should not automatically be read negatively. A shrinking backlog can reflect strong execution when revenue conversion is running at a high pace.

The more useful test is whether fresh order inflows can keep the book at a level that supports the next several years of growth. In defence, this depends on follow-on orders, new product qualifications and India's broader indigenisation programme. In industrial explosives, the key drivers remain mining activity, infrastructure demand and overseas expansion.

Management has stated that, based on H1 performance, the strength of the order book and business opportunities, it expects to surpass its previously stated FY27 annual guidance. That is an important upgrade in tone after the company had entered FY27 with revenue guidance of ₹14,000 crore.

Capex and Working Capital Are the Next Quality Tests

Rapid growth is being supported by a substantial investment programme. Solar Industries incurred ₹873 crore of capex during H1 FY27, while its earlier FY27 plan was around ₹2,050 crore.

The company is investing across domestic explosives, defence capacity and new technology areas. This creates a strong platform for future growth, but also means that free cash flow can lag reported earnings during the expansion phase.

Working capital is another important monitorable. Working-capital days stood at 108 in H1 FY27. For a company growing at 70% in the first half, even stable working-capital intensity can absorb significant absolute cash.

The balance sheet currently provides room. Net debt stood at ₹1,177 crore and net debt-to-EBITDA was only 0.29x. This is a comfortable level before taking into account the larger capital requirements associated with the Omnia transaction.

The quality of the next earnings cycle will therefore depend on whether Solar Industries can maintain high returns while both capex and working capital expand. Revenue growth alone will not be enough if incremental capital employed rises faster than operating profit.

Valuation: Strong Fundamentals Leave Little Room for Execution Misses

Solar Industries traded around ₹20,000 per share on November 3, 2026, implying a market capitalisation of roughly ₹1.81 lakh crore. Market data placed the trailing P/E close to 90x.

That valuation reflects the scarcity value of a company combining industrial explosives leadership, global expansion and a rapidly scaling defence platform. It also embeds high expectations for several years of earnings compounding.

The valuation tension is therefore straightforward. The operating business is delivering the kind of growth that can support a premium multiple: H1 revenue rose 70%, PAT 84%, defence sales more than doubled and margins remained above 28%. But when a stock trades near 90x trailing earnings, merely meeting guidance may not be enough to drive returns.

The company must continue converting the defence backlog, sustaining international growth, protecting margins and integrating future acquisitions without allowing leverage or working capital to weaken returns. Even a modest reduction in growth expectations can create multiple-compression risk at this valuation.

The stock can therefore remain a high-quality business while still being highly sensitive to execution.

Investor Takeaway

Solar Industries' Q2 FY27 result reinforces the structural transformation already visible in Q1. Revenue rose 69% YoY to ₹3,519 crore, EBITDA reached ₹1,021 crore with a 29.0% margin, and PAT increased 80% to ₹650 crore. Defence now contributes close to 30% of quarterly sales, while international explosives has become the largest segment.

The ₹20,178 crore order book provides multi-year visibility, and management now expects to surpass its FY27 annual guidance. With net debt-to-EBITDA at only 0.29x, the balance sheet remains healthy despite a large capex programme.

The central risk is no longer demand. It is the quality of execution relative to a demanding valuation. Investors should focus on defence order conversion, margin sustainability, working-capital days, capex returns and leverage as the international strategy expands.

Solar Industries has built one of the strongest growth profiles in Indian industrials. The next phase of the thesis is about proving that this growth can compound into cash flow and returns fast enough to justify the valuation already assigned to the business.
