Pune, India / Wolfsburg, Germany — November 27, 2025 — Tata Technologies (BSE: 544028, NSE: TATATECH), a leading global product engineering and digital services company, today announced the successful completion of its acquisition of 100% equity shares of Es-Tec GmbH and its subsidiaries (collectively, Es-Tec Group). This strategic transaction strengthens Tata Technologies’ position as a globally independent engineering, research & development partner to leading automotive innovators.

Notably, the acquisition has been closed ahead of the initial timeline of December 31, 2025 , underscoring Tata Technologies’ commitment to accelerating its growth strategy and delivering enhanced value to customers worldwide.

On September 13, 2025, Tata Technologies had signed a definitive agreement to acquire Es-Tec . The transaction is valued at €75 million, with pay-outs structured against performance milestones. The acquisition brings more than 300 German engineers with deep expertise in ADAS, connected platforms, systems engineering and embedded software into Tata Technologies’ global delivery network.

Strategic Rationale

Tata Technologies’ acquisition of Es-Tec Group delivers immediate strategic and commercial benefits:

  • Direct access to European OEM programmes: The Wolfsburg base positions Tata Technologies at the frontline of vehicle research and electrification programmes with major European OEMs including BMW and Volkswagen.

  • Enhanced domain capability: The addition of specialist German engineering talent strengthens Tata Technologies’ ability to deliver high-value, complex programmes in ADAS and software-defined vehicles.

  • Diversified client footprint: This acquisition accelerates Tata Technologies’ evolution into an independently relevant ER&D partner for multiple global OEMs.

  • Cross-selling and integration synergies: Es-Tec Group’s advanced testing and systems capabilities can be extended to Tata Technologies’ clients across North America, Europe and Asia, while Tata Technologies’ offshore scale and delivery model will support Es-Tec Group’s German OEM customers.

  • Glocal delivery model: The combination of German engineering precision and Indian scale creates a differentiated and compelling right-shoring proposition that will help OEMs reduce costs without compromising on quality.

Warren Harris, MD & CEO, Tata Technologies noted that “This acquisition marks a pivotal step in Tata Technologies’ transformation into a truly global, independent engineering partner. By bringing Es-Tec Group’s deep European domain expertise and premium engineering talent into our network, we strengthen our ability to support OEMs through the most complex technology transitions in electrification, ADAS and software-defined mobility.”

“Joining Tata Technologies enables us to scale our capabilities globally while continuing to serve our German OEM partners with the highest standards of engineering excellence. Together we will accelerate innovation and deliver differentiated value to customers worldwide,” said Marc Wille, MD & CEO, Es-Tec Group
