SEDEMAC Mechatronics IPO Structure: A ₹1,087 Crore Offer for Sale
The SEDEMAC Mechatronics IPO is structured as a book-building public issue with a total issue size of approximately ₹1,087.45 crore. Unlike many IPOs that include fresh capital raising, this offering is entirely an Offer for Sale (OFS) by existing shareholders.
Through the IPO, a total of 80,43,300 equity shares are being offered to the public. Since the issue consists solely of an OFS, the proceeds from the offering will go to the selling shareholders rather than the company itself.
