Carlyle Group fell 1% after UBS downgraded the stock to neutral from buy, cutting its price target to $47 from its prior target of $60.

Analyst Michael Brown sees the risk/reward as balanced, noting that Carlyle’s newer growth businesses are not yet large enough to offset its dependence on flagship fundraising. Carlyle is increasingly likely to miss its 2028 earnings, according to the analyst. 

“We lowered our fee-related earnings multiple to 8 times and price-to-earnings multiple to 8 times in our 50/50 blended SoTP framework,” Brown said. “This reflects an estimated 10.7% three-year CAGR in fee-related earnings from 2025 to 2028, reduced visibility into when flagship funds will begin generating fees and a less diversified growth strategy than faster-growing peers.”
