Task prompt

What the agent was asked to do

Evaluate acquisition of WhiteHorse Finance (WHF) by editing the ‘Target-TPVG’ tab in merger model using WHF’s 2024 financials. Use a share price of $7.20 (as of 11/26/2025). Output two sensitivity analyses on the Post-Deal Pro Forma tab in the merger model file, showing: NAV per share (2 decimal places), NII per share accretion (%, 2 decimal places) for the WHF transaction. In each case, show analyses for: - Bid Premiums: 30% and 35%. - Cash Consideration Mix: 30% and 40%.
