Task prompt

What the agent was asked to do

Edit the Valuation Summary tab of the REIT model, showing the implied upside/downside percentage for the Mid case of Scenario 1: Current Valuation. - EV/EBITDA multiple: use 50% and 55% of the average multiple for Data Center REITs on the Comparable Companies tab, excluding the highest and lowest companies by market cap. - Current trading price: two columns as 10% and 20% higher than the Strategic Offer share price. Assume revenue growth % is now 9% and EBITDA Margin % is now 41% for the entirety of the projection period and use 2029E EBITDA instead of 2025E EBITDA in the Mid case of Scenario 1: Current Valuation. Round to the nearest two decimal points.
