Management Comments: -

Dr. Harshad Mehta, Non-Executive Chairman, RIR Power Electronics Ltd , said: “Our Q3 performance reflected temporary moderation arising from the realignment of select orders due to customerdriven scheduling changes, the implementation of new labour codes, and an increase in raw material consumption cost. We anticipate a recovery and stronger momentum in the upcoming quarters. Ramesh Kumar’s leadership will play a pivotal role in driving our growth agenda, broadening our product portfolio, and supporting RIR’s ambition to expand its global presence in the power semiconductor industry. With the Odisha clean-room facility nearing completion and a strengthened leadership team in place, RIR remains firmly focused on execution excellence and long-term growth.
