Task prompt
What the agent was asked to do
You have access to the accretion dilution model. Create a new sheet and tell me the Proforma Interest Coverage for 2027 and 2028. In doing so, assume: - Aptar's Interest expense as a percentage of sales in sheet "Aptar_Historicals" is now 2% for the projection period (2025E - 2030E) - Aptar's Total OPEX as a percentage of sales in sheet "Aptar_Historicals" is now 25% for the projection period (2025E - 2030E) - Aptar's Tax Rate as a percentage of sales in sheet "Aptar_Historicals" is now 35% for the projection period (2025E - 2030E) - Interest on Existing debt remains unchanged. - Cost synergies target in sheet "Synergies" is 35% - Synergies in sheet "Synergies" will be 50% realized in 2025, 2026 and 2027 and 100% in 2028 and after - Cost to achieve synergies in sheet "Synergies" will be 0% Perform the calculations in Euros in thousands and round to one decimal place.
