Laredo-based holding company ranked #50 in its 50th year

(February 10, 2016) LAREDO, Texas — International Bancshares Corporation (NASDAQ: IBOC) has been ranked among the nation’s best by business publishing giant Forbes magazine. The $12.1 billion Laredo-based multibank financial holding company ranked 50th on the prestigious list of the 100 Best Banks in America based on factors such as its asset quality, capital adequacy, growth and profitability.

The selection comes as IBC celebrates its 50th year of service in Texas and Oklahoma. Since its founding in 1966, IBC has grown to serve 88 communities with 208 branches and more than 320 ATMs. It is one of only 13 banks on the Forbes list to increase its dividends by at least four percent for six consecutive years.

“Forbes is confirming what our employees and clients already know,” said International Bancshares Corporation President, Chairman of the Board and CEO Dennis E. Nixon. “IBC is among the strongest, most reliable banking companies in America. It’s gratifying to be recognized by industry experts; however, our top priority is our relationship with our clients. Staying true to our commitment to the communities we serve, and ‘Doing More’, is the foundation of everything we do.”

The seventh annual “100 Best Banks” list is developed by Forbes based on data compiled by SNL Financial of Charlottesville, Virginia. This year’s rankings evaluated factors including nonperforming assets as a percent of assets, reserves as a percent of non-performing

Among other factors, IBC’s ranking was based on its $12.1 billion in assets, a 10.6 percent return on average total common equity and a 52 percent efficiency ratio.
