International Bancshares to Move Listing to Texas Stock Exchange

International Bancshares Corporation is transferring its primary stock listing from the Nasdaq Stock Market to the Texas Stock Exchange, becoming one of the early major regional financial institutions to embrace the new regional exchange venue.

Trading on the Texas Stock Exchange is scheduled to begin at market open on Monday, Oct. 19, 2026, while the company's common stock will continue trading on Nasdaq through the close of market on Friday, Oct. 16, 2026. The financial institution will maintain its existing ticker symbol, 'IBOC', and the corporate announcement confirmed that current shareholders do not need to take any action regarding the transfer.

"Texas has long been a place where free enterprise principles have allowed businesses to build, grow and lead, and we are excited to continue that legacy by bringing IBC's primary listing to the state where our business has prospered for 60 years," said Dennis E. Nixon, IBC's chairman and CEO.

Asset Growth and Historical Milestones

Founded in Laredo, Texas, in 1966, International Bancshares Corporation started operations with less than $1 million in assets. Over six decades of regional expansion, the organization has scaled into a $17 billion banking institution serving communities across Texas and Oklahoma.

"IBC is one of the great franchises in Texas banking, opened in Laredo in 1966 with less than $1 million in assets and grown into a $17 billion institution trusted by generations of businesses and families," said James H. Lee, chairman and CEO of TXSE.

Following the October transition dates, corporate filings show that executive leadership plans to formally celebrate the exchange shift at a closing-bell ceremony scheduled for Dec. 7, 2026, in Houston, Texas.

What the Exchange Migration Means

Regional stock exchanges have sought to attract homegrown corporations by emphasizing localized regulatory support and alignment with state-specific business climates. For International Bancshares, the relocation highlights a strategic preference for a venue centered entirely within its core operating geography.

The structural shift occurs as emerging exchanges vie for mid-cap and large-cap liquidity away from traditional coastal operators like Nasdaq and the New York Stock Exchange. By maintaining uninterrupted trading continuity under the same ticker symbol, IBC aims to execute the exchange migration without causing operational friction for retail or institutional investors.
