Transaction Trends
Unsolicited & Hostile Transactions
- Heading into 2025, market conditions—including interest rate trends and shifting regulatory priorities—appeared ripe for an uptick in unsolicited or hostile activity.
- It is too early for sweeping projections, but hostile bids in 2025 have significantly outpaced activity in recent years: More than 30% of public overtures have been unsolicited and one bid has turned hostile in the first five weeks of the year.
- Hostile activity had moderately declined in 2023 and 2024, as both a percentage of overall M&A activity (under 20%) and raw count (under 40 annually).
- Assuming the upward trend continues, readiness planning by boards and advisors (e.g., defensive profile analyses and proactive stakeholder engagement) will become even more critical in the months ahead.
Acquisition Premiums
- Acquisition premiums broadly declined in 2023-2024. Among sponsor-led acquisitions, average premiums fell from 55% in 2022 to 33% in 2024. YTD 2025 metrics indicate a moderate increase (38%).
- Among strategic transactions, average premiums fell from 48% in 2023 to 40% in 2024, with a marginal increase so far this year.
- Prior to 2023, sponsor buyers on average offered substantially higher premiums (10%+) than strategic acquirers. Following turbulent M&A conditions in recent years, including increased borrowing costs, premiums offered by strategic firms have moderately surpassed sponsor deals on average. Median premiums have largely synchronized across buyer types over the past two years.
