Management comment:

Dr. Harshad Mehta, Non-Executive Chairman, RIR Power Electronics Ltd, said

“FY25 has been a transformative year for RIR Power Electronics. We delivered strong revenue growth of

over 29%, reflecting robust demand for our high-performance power semiconductor solutions across key

sectors such as grid infrastructure, defense, renewables, and electric mobility. Our consistent profitability

amid strategic investments demonstrates the resilience of our business model and the strength of our

operational execution.

What excites me most is the momentum we’ve built toward India’s first Silicon Carbide (SiC) device

manufacturing facility in Odisha. The acquisition of advanced process know-how from Sicamore

Semiconductor, USA, marks a decisive step in our journey toward deep technology capability and import

substitution. This initiative will not only elevate India’s position in the global power electronics ecosystem

but also create a sustainable domestic supply chain for high-efficiency devices used in emerging technologies

like green hydrogen, EVs, and railways.

As we enter FY26, our focus remains on execution excellence, technological innovation, and value creation

for all stakeholders. We are confident that RIR is well-positioned to play a leading role in India’s

semiconductor ambitions while continuing to deliver profitable growth.”
