Sedemac Mechatronics, a Pune-based deeptech firm, has filed its Draft Red Herring Prospectus (DRHP) for what could be one of India's scarce deeptech IPOs. The filing shows significant profit growth in FY25, driven by reduced finance costs, and a cleaner balance sheet due to debt reduction. However, the company faces structural risks from the accelerating shift to electric vehicles and high revenue concentration, with TVS Motor accounting for a large portion of its revenue. The IPO is structured entirely as an offer for sale, indicating existing investors are seeking liquidity.
