The financial-communications league tables came in for the first half of 2026, and the usual names sit on top. FGS Global held its lead in M&A advisory work, according to Mergermarket’s first-half rankings, while Joele Frank kept its grip on the activism-defense category that has long been its signature.
League tables in this corner of the industry track which firms advised on the most deals and the largest ones. They shape reputation, and reputation is much of what a communications firm sells. A board weighing which adviser to hire for a bruising campaign looks hard at who has done the most of them.
O’Dwyer’s reported FGS holding the top spot again, a position it has defended across several rankings. The firm handles a heavy volume of large-cap M&A, the kind of transaction that generates the deal credits these tables count.
Joele Frank plays a different game and wins it. The firm’s activism-defense practice advises companies fending off hedge funds, dissident investors and founder-led proxy fights, and it has topped the defense rankings on Bloomberg and other scorecards for years running. When an activist surfaces on a company’s register, Joele Frank’s defense team is one of the first calls a board makes.
The split between the two firms reflects how the field has specialized. M&A messaging and activism defense draw on different skills. One is about selling a transaction; the other is about protecting a board under attack. A firm can lead one table without touching the other, and clients pick advisers by the fight in front of them.
Activism has kept defense specialists busy. Campaigns have grown more frequent and more aggressive, reaching companies of every size, and the settlements that end them increasingly hand activists board seats. That environment rewards firms with deep experience, which helps explain why the same names keep appearing atop the industry’s most-decorated agencies.
The economics favor specialization. Activism defense and M&A communications command premium fees because the stakes run high and the work is episodic, arriving in bursts when a deal breaks or an activist files. Firms that dominate a category can charge accordingly, and the league-table credits double as marketing that keeps the mandates coming. FGS built its lead through sheer deal volume after a run of mergers assembled the firm. Joele Frank grew the opposite way, staying independent and concentrating on defense and high-stakes situations rather than chasing every transaction. Two strategies, two different tables, and both firms sitting atop the one they chose.
For companies, the rankings are a shorthand. They can’t measure how a firm performs inside a specific fight, but they do show which shops handle the most volume and survive the most contests. That track record is why boards pay premium rates when their control or their strategy is on the line.
Half-year tables are a snapshot, not a verdict. The second half could reshuffle the M&A order as new mega-deals land. Activism defense tends to move more slowly, though, and Joele Frank’s long hold on that category suggests its lead won’t be easy to dislodge.
