Task prompt
What the agent was asked to do
Calculate an updated implied sponsor equity at entry with FY2032 exit. Use the MFC LBO model and the assumptions below: - Reduce the TL-B leverage multiple from 3.0x LTM EBITDA while lowering the yield 6.50%. - Increase the senior notes leverage multiple from 2.0x to 3.5x LTM EBITDA and Increase the yield from 9.50% to 11.0%, apply the rate to the beginning balance each year, and assume full PIK treatment, with annual interest accruing and being added to the ending principal balance and paid in FY2032 (no interim cash interest payments). - Maintain revenue growth at 6.0% per annum from FY2026 through FY2032 and use target IRR of 25%. Leave all other assumptions unchanged. Report in Canadian dollars (C$), rounded to the nearest million. State your answer to me right here.
