Stagwell posts $632M Q2 revenue, $171M new-business haul and $109M adjusted EBITDA

Stagwell reported a strong second quarter: net revenue of $632 million (up 6% year‑over‑year), $171 million in new business (a 45% increase YoY), and adjusted EBITDA of $109 million (up 15% YoY). Year‑to‑date net revenue stands at $1.22 billion, a 5% increase from 2025. Growth from Stagwell’s top 100 clients was 16%.

Chairman and CEO Mark Penn told investors on the earnings call that Stagwell’s performance was driven by its aggressive strategy for new business.

What this signals for the agency market Stagwell’s results underline how a renewed emphasis on winning new business can translate quickly into revenue and margin gains at holdco scale. New‑business revenue rising 45% YoY alongside 16% growth from the top 100 clients shows both stronger client acquisition and deeper existing‑client traction, a useful one‑two punch for any roll‑up pursuing organic expansion. An adjusted EBITDA increase of 15% on a mid‑single‑digit top‑line gain suggests operational leverage is kicking in as new business converts to profitable work.

For agency founders and buyers, the takeaways are straightforward: invest in predictable new‑business capability and client retention if you want to move both revenue and EBITDA multiples. For private equity and holdcos, Stagwell’s figures show the payoff from combining sales muscle with scale, not just cutting costs, but accelerating growth.
