Blackstone is to become a corporation in July after tax cuts implemented by US President Donald Trump’s administration made its complex partnership status redundant.

The company’s chief executive, Stephen Schwarzman, told CNBC that becoming a corporation would double the number of people able to own Blackstone stock. He added that the publicly traded partnership model it has used since its 2007 IPO had become “irksome”.

Blackstone shares rose 9.5 percent in premarket trading following the news and the publication of its Q1 earnings statement. The latter showed the firm’s Q1 revenues to have risen to more than $2 billion, a 14 percent increase on the first quarter of 2018.

In a statement released alongside its earnings, Schwarzman said: “I am pleased to announce the compelling next step in Blackstone’s evolution as a public company: the firm’s conversion to a corporation.

“We believe the decision to convert will make it significantly easier for both domestic and international investors to own our stock and should drive greater value for all of our shareholders over time.”

Blackstone’s partnership structure was designed to reduce its tax bills. However, following significant tax cuts for corporates introduced by President Donald Trump last year, the arrangement is seen as being unnecessarily cumbersome. KKR took similar steps in 2018.

Blackstone’s net income in Q1 reached $1.1 billion, up from $842 million in the first quarter of 2018. Annual net income reached $3.5 billion during the 12 months to 31 March. This was below the figure posted a year ago, when earnings for the previous 12 months hit $3.8 billion.

Blackstone’s assets under management increased by 14 percent year-on-year to $511.8 billion at the end of Q1. The firm also had record inflows of $42.9 billion during the quarter, bringing inflows for the year to $125.7 billion.

The firm’s corporate private equity strategy had the best investment performance over the 12 months, up 17.7 percent on the previous year. Its performing credit division’s investment performance was 10.2 percent. However, its distressed debt operation had a more difficult year with investment appreciation of just 0.7 percent.

Real estate accounted for the bulk of its earnings, bringing in $660 million during the 12-month period. Private equity accounted for $361 million, hedge funds earned $289 million and fees on credit brought in $184 million.

The merger of Brookfield Asset Management and Oaktree Capital Management has dominated headlines and drawn comparisons to Blackstone, including AUM size. At the time of the deal, Brookfield’s and Oaktree’s combined assets were worth $475 billion. However, Blackstone chief financial officer Michael Chae said that number includes levered funds. On that basis, Blackstone’s AUM would be $804 billion, he added.

Editor’s note: The comparison of AUM between a Brookfield-Oaktree and Blackstone has been updated to reflect the firms’ different AUM calculation methods.
