AI summary

Megasoft Limited's board has noted the NCLT Chennai Bench order dated December 16, 2025 sanctioning the Scheme of Amalgamation with Sigma Advanced Systems Private Limited. The scheme became effective on December 31, 2025, with an appointed date of April 1, 2024. Under the scheme, 316 equity shares of Megasoft (face value INR 10) will be issued for every 100 equity shares held in Sigma Advanced Systems. The record date to identify eligible shareholders of the transferor company is January 14, 2026. Post-amalgamation, Megasoft will rename itself to 'Sigma Advanced Systems Limited' and consolidate its authorised share capital to INR 250 crore. The board also acknowledged two new group entities — Indrajaal Drone Defence India (Associate) and Indorus Opto Sights (Subsidiary) — and approved corporate guarantees totalling GBP 8.80 million on behalf of UK-based Nasmyth Group.

Likely market impact

This is a reverse merger that effectively transforms Megasoft into Sigma Advanced Systems, bringing in drone defence and opto-sights businesses under a listed entity. Shareholders of Sigma Advanced Systems will receive Megasoft shares, and the stock will trade under a new name and identity, potentially re-rating based on the new business profile. The GBP 8.80 million contingent liability from corporate guarantees for a UK group is a modest risk to monitor.
