SYDNEY, March 22 (Reuters) - Blackstone Group Inc BX.N proposed a buyout of Australia's Crown Resorts Ltd CWN.AX in a deal valuing the casino operator at $6.2 billion, a markdown from the troubled company's value a year ago but a possible reprieve from regulatory pressure.
Crown shares leapt more than 20% after it disclosed the informal offer on Monday, passing Blackstone's indicative price of A$11.85 as investors wagered a bigger payment could be in the offing from the world's No. 1 private equity firm or another suitor.
"It's nice to get a bid, and now it's about price discovery," said John Ayoub, a portfolio manager at Wilson Asset Management, which has Crown shares.
"These stocks are trading at trough earnings and I wouldn't be surprised to see further activity in the sector."
If Blackstone's takeover were to succeed, it would round out a portfolio of gambling-related assets from Las Vegas to Spain with resorts in three Australian cities.
But it would get a company in crisis after Crown lost its licence to operate a flagship new casino on Sydney's waterfront last month amid allegations of money laundering and links to organised crime.
It also faces inquiries in the other two Australian states where Crown is licensed to operate.
Australia's financial crimes agency meanwhile is investigating Crown over money-laundering allegations, and the company faces two civil lawsuits accusing it of failing to disclose risks which led to share price declines.
Blackstone's indicative offer was short of the stock's trading levels before concerns about the coronavirus caused market gyrations in early 2020.
Crown shares closed up 21% at A$11.97. Investors often trade below an indicative offer price to allow for the possibility of a deal failing to eventuate.
"Blackstone couldn't get away with a price like this if the casinos weren't being affected by COVID and the management issues at the same time," said Nathan Bell, portfolio manager of Intelligent Investor, which has Crown shares.
"It's only an opening bid. It's a messy situation and offering to acquire a casino is a complex affair at the best of times due to all the regulation."
Crown said its board had not yet formed a view on the proposal but would talk to "relevant stakeholders including regulatory authorities".
Company founder James Packer, the top shareholder with a 36% stake, would receive about A$2.9 billion from the deal.
Packer declined to comment. Blackstone, Crown's second-largest shareholder with 9.99%, confirmed the approach but declined to comment further.
BAD TO WORSE
Packer sold out of casinos in Macau and the United States and began a series of attempts to take Crown private after 18 staff were jailed in China in 2016 for violating anti-gambling laws.
Three years later media reports accused Crown of knowingly doing business with junket - or gambling tour - operators linked to organised crime, leading to findings at a subsequent regulatory inquiry of "dysfunctional" management where Packer dominated the board from afar despite holding no official role.
The inquiry called by the gaming regulator in New South Wales said Packer's "remote manouevring" would have to be resolved before Crown could hold a casino licence in the state, putting the company's billionaire founder under immense pressure to sell down his stake.
Crown's new tourist-targeted Sydney casino opened in December without tourists due to pandemic-related border closures, and without gambling because of restrictions put on it during the probe.
It has lost about half its board including its CEO since the inquiry declared Crown unfit for a Sydney licence in February. the conditions of the Blackstone proposal, the private equity firm itself would need to be found suitable to run a casino by Crown's regulators.
The New South Wales state Independent Liquor and Gaming Authority said it was aware of the approach but declined to comment further.
