Revenue growth: order wins translating to revenue
As Sigma Advanced Systems has accelerated order wins, particularly in FY26, its annual revenue has grown from ₹41.60 crore in FY25 to ₹491.88 crore in FY26, representing a year-on-year growth of +1082.4% based on the latest annual data.
Working capital and execution capacity
The balance sheet supports execution with a current ratio of 1.42x and total liabilities/equity of 1.26x. Operating cashflow has been positive over the last four years, with ₹36.70 crore generated in FY25. Free cashflow remained positive at ₹19.40 crore in FY25.
What to watch
- Execution rate: With a backlog covering 38.60 quarters of revenue, the ability to scale production and deliver on time across both India and UK facilities is a key operational consideration.
- OPM trajectory: Monitor whether the OPM of 15.85% seen in Q1FY27 sustains as new orders execute. Margin quality may vary between domestic defense contracts and international aerospace components.
- Client concentration: The majority of the disclosed order book comes from Rolls-Royce entities and North American customers. The Home Ministry, Government of India order adds domestic government exposure.
- Working capital cycle: As orders execute, monitor receivables days and cash conversion cycles to ensure liquidity remains adequate for scaling operations across multiple geographies.
Key observations
- Backlog signal: The total disclosed order book of ₹9,398.00 crore covers 38.60 quarters of average quarterly revenue. At this level, execution capacity is a primary operational factor.
- Valuation check (as of 25 Aug 2026): P/E of 78.2x against ROCE of 9.01%. Price-based metrics are as of 25 Aug 2026 and will change; ROCE is from audited financials.
- Margin stress: Net loss of ₹1.00 crore in Q3FY26; execution stress was visible in quarterly data prior to the recent recovery seen in Q4FY26 and Q1FY27.
