How this is computed
For each Alexion Pharmaceuticals deal we find the median total deal value of comparable transactions (same therapeutic area + phase, falling back to TA-only with ≥3 peers). The buyer’s deal divided by the peer median is the per-deal premium. We trim outliers, take the trimmed mean, and clamp to [0.7×, 1.5×] to reject data errors. Confidence scales with sample size.
Trimmed mean of 3 disclosed deal premiums vs. peer medians. Raw premium 0.845, clamped to [0.7, 1.5].
