AMMB said on Thursday that its revenue for the quarter rose 7.9% to RM1.95 billion from RM1.81 billion in 2011.
Earnings per share was 11.47 sen compared to 10.54 sen previously, while net assets per share was RM3.70.
AMMB declared a final dividend of 13.5 sen.
AMMB managing director Ashok Ramamurthy in a statement on Thursday said FY2012's improved results demonstrated the group's disciplined execution of the year's priorities.
"In delivering profitable growth and rebalancing, we achieved our fifth consecutive year of record performance. Loans and deposits growth remained sound while credit quality continued to improve with lower allowances," he said.
On the banking group's outlook, Ramamurthy said that in 2012, Malaysia's economic growth was expected to remain resilient, driven by domestic demand and private investment expansion.
Incentives and plans announced under the 2012 Budget were likely to encourage private consumption, he said.
He said AMMB expected gross domestic product to experience growth of 4%-5% in 2012, but several risks such as the Euro debt crisis and lower exports remained.
"In the Malaysian banking industry, the rollout and implementation of projects under the Economic Transformation Programme will continue to support lending and capital market activities.
"However, new responsible lending guidelines will moderate consumer loans demand. We anticipate banks to adapt to the changes, but margins will still be impacted by ongoing competition for loans and deposits," he said.
