H/Advisors Abernathy’s proprietary research – ‘When Deals Spring a Leak Volume V’ –provides corporate leaders, Boards of Directors and M&A advisors with key insights and trends from the past year of dealmaking. Building on the firm’s proprietary database of M&A transactions, our Research & Insights team analyzed announced transactions valued at $1 billion and greater to understand the frequency at which deals leak as well as how a leak may affect perception of the transaction among media and digital audiences.

H/Advisors Abernathy’s data analysis found that 31% of announced transactions valued at $1 billion and greater in 2024 leaked prior to the official announcement. Deals valued at $10 billion or greater continued to leak at a significantly higher rate, at 64% in 2024, a substantial increase from 43% in 2023.

“While numerous factors affected the ability of companies and dealmakers to get transactions across the finish line in 2024, our research shows that the persistent risk of leaked negotiations remains a hurdle that companies and dealmakers must continue to overcome,” said Tom Johnson, CEO of H/Advisors Abernathy. “Having roughly two-thirds of the largest transactions exposed prior to an announcement is an extraordinary number and continues to demand that companies spend time early in the negotiation process preparing to manage through such scenarios.”

Additional key findings from When Deals Spring a Leak Volume V include:

Transaction leaks are occurring earlier in the deal process, on average, 52 days in advance of an announcement, with 19% of leaks occurring within two days of the deal’s official announcement.
Entertainment, Leisure and Media remained the “leakiest sector”, increasing to 62% of deals leaking to media before the official announcement, up from 45% in 2023. Deals in the Tech sector also leaked at a substantially higher rate, up to 46% leaking from 26% in 2023.
On average, leaks rank among the top five most visible news moments of the year for both buyer and target companies.
Nearly three in four mentions of a leak start with an online news story and then travel to social media, led by X (16% of leak mentions) and LinkedIn (10% of leak mentions) where attention spreads rapidly.

“Amid an M&A market that continues to be unpredictable, leaked transactions and marketplace rumors will continue to pose challenges to dealmakers and companies exploring transactions, as well as their advisors. Our annual analysis of M&A leaks, powered by our proprietary deals database, is one example of how our experienced team harnesses data and analytics to inform client counsel. We are proud to bring a distinctive, customized and results-focused approach as we partner with our clients to successfully navigate transformative transactions,” added Dan Scorpio, Managing Director and head of the M&A practice at H/Advisors Abernathy.
