Synopsis: A Hyderabad-based aerospace and defence company has transformed itself through a major merger, a UK acquisition, and a fresh export order – delivering extraordinary returns to early shareholders in under four years.
When a listed company quietly reinvents itself – changing its name, absorbing a private entity, acquiring a UK aerospace group, and watching its promoter holding nearly double – the stock market tends to take notice. This company’s share price journey from Rs. 35 in July 2022 to around Rs. 480 today, a rise of nearly 1,200%, tells a story worth examining closely.
A Company Reborn
Sigma Advanced Systems Limited, formerly known as Megasoft Limited, is today a very different entity from what it was just a few years ago. Originally a software company, it has pivoted decisively into the aerospace and defence sector, which is now its sole business segment. The name change reflects this transformation, and so does almost every financial metric in its FY26 results.
The most consequential structural change was the NCLT-approved merger of Sigma Advanced Systems Private Limited into Megasoft Limited, with an appointed date of April 1, 2024, and the court order arriving in December 2025. This amalgamation fundamentally reshaped the company’s financials. The promoter holding surge – from 35.07% to 71.22% – is a direct outcome of this merger-driven equity restructuring, not open market buying.
FY26 Results: Revenue Surges, PAT Skyrockets
On a consolidated basis, the company reported revenue from operations of Rs. 491.88 crore for FY26, compared to Rs. 107.36 crore in FY25 – a massive jump driven largely by the consolidation of Nasmyth Group, a UK-based aerospace precision engineering company, from November 2025 onwards. The acquisition was executed through a wholly owned UK subsidiary, Sigma Advanced Systems UK Limited, incorporated during the year.
Net profit on a consolidated basis came in at Rs. 268.04 crore for FY26, compared to a loss of Rs. 13.98 crore in FY25. However, two large one-time items sit inside this number, and understanding them is important.
Understanding the One-Time Gains
The company sold a piece of landed property in April 2025, booking a gain of Rs. 184.64 crore. Separately, it divested its entire stake in Extrovis AG, a foreign associate, during the year. Together, these two transactions contributed a very large chunk of the reported profit. Think of it this way – if you sold your house and booked a profit, your income that year would look unusually high, but your salary income (the recurring part) would be much lower. The same logic applies here.
The consolidated profit of Rs. 268.04 crore is real, but a significant portion of it came from selling assets, not from running the core business. Strip those gains out, and the underlying operating profit, while improved, is considerably more modest. This does not make the results bad – asset monetisation is a legitimate business decision – but investors should read the headline profit number with this in mind.
The Nasmyth Acquisition: The Real Growth Engine
Nasmyth Group, acquired through the UK subsidiary, is the headline strategic move. It is a precision aerospace engineering group with multiple operating entities across the UK, covering surface treatment, composites, engineering, and calibration businesses. Importantly, Nasmyth’s financials have been consolidated only from November 2025, meaning FY26 results capture barely five months of its contribution. A full twelve months will reflect from FY27 onwards, which is why the forward revenue picture looks materially different from what FY26 shows.
Fresh Export Order Adds to the Story
Adding to the momentum, the company has received an export order worth Rs. 208 crore for the supply of 40,000 artillery shell bodies. This is a meaningful win on multiple counts. It signals that the company’s manufacturing capabilities are being recognised in global defence supply chains, and it positions Sigma as a participant in India’s growing role as a defence exporter. With the Indian government actively pushing defence exports as a national priority, orders of this nature carry both revenue and strategic significance. This order will reflect in future revenue and adds visibility to the earnings pipeline beyond FY26.
The company also holds a stake in Indrajaal Drone Defence India Private Limited as an associate, which contributed Rs. 2.46 crore to consolidated profit in FY26 through the equity method – a small number today, but a strategic hedge into the drone defence space that India is investing heavily in.
A Transformation Still Unfolding
The full story of Sigma Advanced Systems is not yet written. The Nasmyth acquisition will show its complete financial impact only from FY27. The artillery shell export order will add revenue going forward. The drone defence associate remains an early-stage bet. What is clear is that the company has moved a long distance from its software origins – it now has manufacturing muscle, an international aerospace footprint, a meaningful export order, and a promoter that has dramatically increased its skin in the game. Whether the current stock price fully prices in these developments or leaves room for further upside is a question each investor must answer for themselves, but the building blocks of a genuine defence manufacturing business are visibly falling into place.
