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.

Grading rubric

Criteria and grader verdict (showcase run)

States Pro forma interest coverage for 2027 is 5.2x
Fail
Evidence: <TEXT_RESPONSE> states, “Using Pro Forma EBITDA / Pro Forma Interest Expense... 2027E | 14.8x.” Assessment: The criterion requires that the response states Pro forma interest coverage for 2027 is 5.2x. It instead states 14.8x, so this fails.
States Pro forma interest coverage for 2028 is 6.2x
Fail
Evidence: <TEXT_RESPONSE> states, “2028E | 16.3x.” Assessment: The criterion requires that the response states Pro forma interest coverage for 2028 is 6.2x. It instead states 16.3x, so this fails.
