Data Patterns (India) Limited has announced the acquisition of ST Advanced Composites Pvt. Ltd. for ₹1.50 crore in equity shares, with an additional ₹8.50 crore loan to the target company. This strategic move aims to vertically integrate STAC’s advanced composite engineering capabilities, including RF-transparent radomes and aerospace-grade structural components, into Data Patterns’ existing radar electronics manufacturing. The acquisition is expected to enhance margin, reduce dependency on third-party vendors, and strengthen the company’s position in integrated subsystem programs.
Data Patterns Acquires ST Advanced Composites
Data Patterns (India) Limited has approved the acquisition of ST Advanced Composites Pvt. Ltd. (STAC), a Chennai-based company specializing in advanced composite engineering for the aerospace and defence sectors. This strategic acquisition, announced on July 30, 2026, aims to integrate STAC’s expertise in RF-transparent radomes, aerospace-grade structural components, and defence composite solutions directly into Data Patterns’ operations. The company will acquire 100% stake in STAC, making it a wholly-owned subsidiary.
Strategic Rationale and Impact
The primary objective of this acquisition is to achieve vertical integration. Data Patterns currently designs and manufactures radar electronics but procures essential radomes and composite structures externally. This reliance has led to margin leakage and schedule dependencies. By bringing STAC’s capabilities in-house, Data Patterns anticipates enhanced control over its supply chain, improved margins, and a strengthened ability to bid for integrated subsystem programs. The acquisition is expected to expand the addressable value per program by an estimated 1.3-2.0x.
Transaction Details
The total consideration for the acquisition involves ₹1.50 crore paid towards the acquisition of equity shares from the promoters of STAC. Additionally, Data Patterns will provide a loan of ₹8.50 crore to ST Advanced Composites to enable it to settle its existing liabilities. The transaction is expected to be completed within 3 months.
Target Entity Background
ST Advanced Composites specializes in RF-transparent radomes, aerospace-grade structural components, and defence composite solutions, offering end-to-end capabilities from design to testing. The company’s core focus areas include aerospace, defence, and UAV structures. Its provisional turnover for FY 25-26 was approximately ₹416.85 Lakhs. The authorized share capital of STAC is ₹50,00,000, divided into 5,00,000 equity shares of ₹10 each.
