KUALA LUMPUR, June 1 (Reuters) - Malaysia's RHB Bank Bhd RHBC.KL and AMMB Holdings Bhd (AmBank) AMMB.KL said they will begin merger talks, in what could be the Southeast Asian nation's biggest banking deal and create a group worth about $9 billion at current prices.
The banks have received the nod from the Malaysian central bank to commence the merger negotiations, they said in a joint statement on Thursday. The transaction is expected to be an all-share deal and the two banks have until Aug. 30 to exclusively discuss a deal, they said.
The potential merger would reinforce RHB's ranking as the fourth largest Malaysian bank by assets behind Maybank MBBM.KL , CIMB Group Holdings CIMB.KL and Public Bank PUBM.KL . AmBank is currently the country's sixth biggest bank.
Source told Reuters on Wednesday that RHB would be the acquirer in the potential merger. AmBank has a market capitalisation of 15.7 billion ringgit ($3.66 billion), while RHB has a market value of about $5.0 billion. full takeover at those price levels by RHB would put it above the 2006 acquisition of Southern Bank by Bumiputra-Commerce Holdings for $1.74 billion, making it the biggest Malaysian banking deal, according to Thomson Reuters data. Bumiputra-Commerce eventually became the current CIMB Group after a series of mergers and a rebranding exercise.
Trading in shares of RHB and AmBank were suspended, ahead of the announcement.
In a research note ahead of the merger announcement, UOB Kay Hian analyst Keith Wee Teck Keong said RHB's shares are likely to react negatively to the announcement as the revenue synergies between the two groups are not compelling.
"We opine that such a merger would require a fair degree of cost rationalisation given the degree of operational and revenue duplication between AMMB and RHB," he said.
ANZ Banking Group ANZ.AX , which owns a 24 percent stake in AmBank, has been weighing a sale of its stake since early last year, partly due to AmBank's involvement in a political scandal linked to state fund 1Malaysia Development Berhad and Prime Minister Najib Razak, sources have said. has been buffeted by allegations of graft and financial mismanagement at 1MDB and in particular by revelations of the transfer of hundreds of millions of dollars into his AmBank accounts in 2013.
Najib has denied any wrongdoing and said he did not take any money for personal gain. 1MDB is the subject of money laundering investigations in at least six countries, including the United States, Singapore and Switzerland.
In 2015, AmBank was slapped with a 53.7 million ringgit fine by the Malaysian central bank for breaching certain financial regulations. ($1 = 4.2860 ringgit)
