How do you use Precedent Transactions to estimate the control premium?
Control premium = (Offer Price − Pre-Announcement Stock Price) / Pre-Announcement Stock Price. Standard data point: the share price 1 day or 30 days before the announcement date. A 30-day average reduces the noise from leak rumors.

the stock is $40 before the announcement, the offer is $52 → a 30% control premium. Historical market median: 25–35% for strategic buyers, 20–30% for financial buyers.
if your target is valued at $1bn on trading comps and the sector control premium is 30%, the implied acquisition value is $1.3bn. Pitfall: the pre-announcement price may already be leak-affected → the control premium is understated. Fix: use a 60-day average as the baseline.
'Sector control premium median 28% (n=12 deals 2022–2025); we apply 25% to trading-comps-derived value as M&A bid-floor estimate.'
