NEW YORK - Blackstone said on Thursday its second-quarter distributable earnings rose 3% from a year earlier, as a jump in asset sales in its private equity and credit divisions more than offset a slump in its real estate arm.

The New York-based investment firm's results underscore how a long spell of high interest rates has dragged down some aspects of its business while buoying others.

High rates have weighed on Blackstone's real estate value and made dealmaking more expensive, yet they also boosted the worth of its credit assets and helped tame inflationary pressures.

Hopes that the U.S. Federal Reserve will start cutting rates have contributed to a market rally that Blackstone has seized on to cash out on some of its companies for top dollar.

Blackstone's distributable earnings, which represent cash that can be used to pay dividends, totaled $1.3 billion in the second quarter. This translated into distributable earnings per share of 96 cents, slightly short of analysts' average estimate of 98 cents, according to LSEG data.

Blackstone's shares were up 1.6% at $136.98 on Thursday, giving the world's largest manager of alternative assets such as private equity and corporate credit a market value of about $165 billion.

A 16% increase in distributable earnings in Blackstone's private equity unit and a 51% jump in its credit arm outweighed the 19% drop in distributable earnings in its real estate division.

Blackstone's core private equity funds appreciated 2% in the quarter, and the firm took advantage of the elevated market valuations to cash out on $7.8 billion of its private equity assets.

Blackstone's opportunistic real estate funds appreciated 0.3% in the quarter and the firm cashed out on $5.5 billion of real estate assets. Its private credit funds posted a gross return of 4.2% and the firm cashed out on $9.5 billion of credit assets.

The company said it saw about $40 billion inflows to its funds and deployed $34 billion in capital from them in the second quarter, the highest level of investment activity in two years.

In real estate, where Blackstone focused on logistics and rental housing and has been wary of the troubled office sector, the firm has invested $15 billion since the start of the year, nearly 2.5 times what it deployed over the same period last year.

"We are planting the seeds of future value creation," Blackstone Chief Executive Stephen Schwarzman said in a statement.

He highlighted artificial intelligence as a major area of growth and said on Blackstone's quarterly earnings call that the firm held $55 billion in data center assets that are developed or under construction and had identified another $70 billion of potential investments in the sectors.

Blackstone's President Jonathan Gray said on the earnings call that while the firm was prepared for either a Republican or Democratic administration following the U.S. election in November, many of its growth drivers, such as digitization, advances in life sciences and the growth of the private credit industry, would continue regardless.

He added that he expected a Republican-controlled federal government to prioritize fossil fuels rather than renewable energy, and that it could take a different posture on antitrust, where U.S. President Joe Biden's administration has sought to crack down on monopolies.

Fee-related earnings, which Blackstone generates from its management and advisory fees, declined 3% to $1.1 billion year-on-year.

The firm posted record total assets under management of $1.1 trillion in the quarter, up 7% year-over-year, driven by strong fundraising, and also declared a quarterly dividend of 82 cents apiece.
