(Reuters) - U.S. buyout firm Carlyle Group LP CG.O reported a 25% year-on-year drop in its third-quarter earnings on Thursday, driven by lower proceeds from asset sales in its private equity portfolio.

The Washington, D.C.-based firm said a slower pace of exit activity in some of its large buyout funds weighed on the revenue it generated from performance fees. It gets paid such fees when a minimum return for its investors, typically 8%, is generated by its portfolio companies paying dividends or being divested.

Carlyle said its after-tax distributable earnings - the cash available for paying dividends - totaled $146.1 million, down from $194.7 million a year earlier.

However, Carlyle’s after-tax distributable earnings per share of 41 cents came in slightly higher than the average analyst forecast of 40 cents per share, according to Refinitiv.

“While the investment environment remains challenging, our global platform and industry sector-driven driven approach positions us well to drive performance,” Carlyle Co-CEOs Kewsong Lee and Glenn Youngkin said in a statement.

Carlyle's third-quarter results are in line with its peers. Blackstone Group Inc BX.N and KKR & Co Inc KKR.N both reported declines in their distributable earnings, owing to fewer sales of assets from their private equity funds.

Carlyle’s private equity funds appreciated by 1% in the quarter, while its real estate funds appreciated by 3%. By comparison, Blackstone’s private equity and opportunistic real estate funds appreciated by 2.6% and 3.8%, respectively.

Carlyle’s total assets under management stood at $222 billion as of the end of June, down slightly from the $223 billion reported in the previous quarter. Its third-quarter management fees came in at $385 million, up 8% year-on-year.

In July, Carlyle became the first U.S. private equity firm to announce that it will hold shareholder votes and adopt a single-class share structure, as it coverts from a partnership to a corporation effective Jan. 1.

The move was aimed at boosting Carlyle’s stock performance, because it allows the buyout firm to be included in indices that make it more popular with investors. The stock has risen by about 15% since the announcement.
