What the agent was asked to do

Use the valuation model, updating the 'Per Share' and 'Premium' values for the low, mid, and high cases to reflect Blackstone’s acquisition of Company X and the assumptions below. Reply back to me with the per share data in € and the Premium. Round percentages to 1 decimal place. Assumptions to follow - Blackstone acquired Company X in 2020 at an EV of €1000M - Company X revenue was €100M - Company X EBITDA was €50M - Blackstone acquired Company X at a 45% premium - The Stevanato - SVM Automatik transaction is an outlier and should be excluded from the analysis - The Mid EV/EBITDA multiple is the average of the High and Low multiples - Gerresheimer recently completed a capital raise that is not reflected in the base case, issuing10 million shares at €30.00 per share - Gerresheimer used €200M of the proceeds raised to acquire 49% of Company Y that has €50M in EBITDA
