International Bancshares (IBOC) is about to change trading homes, with the primary listing moving from the Nasdaq Global Select Market to the Texas Stock Exchange on 19 October 2026.
Recent trading has been softer, with the share price down about 6% over the past month and roughly 13% lower over 90 days, even though International Bancshares has delivered a 1-year total shareholder return of 1.51% and a 5-year total shareholder return of 72.66%. This points to long term momentum, while short term sentiment cools as investors weigh the Texas Stock Exchange move and the bank’s current earnings based valuation at around 10.1x P/E.
Compare International Bancshares with a curated set of regional lenders by screening for list of solid balance sheet and fundamentals (25 results), which may handle listing changes and valuation resets in a similar way.
International Bancshares now trades at about US$66, while analyst targets cluster near US$87 and intrinsic value models indicate an even wider gap. As the listing shift approaches, the key question is how to determine where fair value genuinely lines up between those anchors.
Price-to-Earnings of 9.9x: Is it justified?
Valuation screens flag International Bancshares as inexpensive, with a P/E around 9.9x at a last close of $66.04, compared with richer peer and sector averages that point to a potential discount in how the bank’s earnings are being priced.
The P/E ratio simply compares what you pay per share with the profits that each share represents. For a regional lender like International Bancshares, it is a quick way to see how the market currently values its earnings power against other banks with similar business models and risk profiles.
Statements indicate that International Bancshares looks cheap on this yardstick when set against both the US Banks industry average P/E of 11.5x and an even higher peer average of 19.8x. That gap suggests investors are currently assigning a lower valuation to its earnings, alongside reported high quality profits, a 12.2% per year earnings growth rate over the past 5 years, a 2.21% dividend yield, and an SWS DCF model estimate that places future cash flow value at $139.71 per share, above the current price.
Compared with sector peers, the contrast is strong. The stock trades at a lower P/E than the broader US Banks group and far below the peer set average, while also screening as 52.7% below the SWS fair value estimate based on future cash flows. That combination of a subdued earnings multiple and a sizable modelled discount indicates that the market is pricing International Bancshares below what these valuation frameworks suggest.

Another View on International Bancshares' Value
There is a different lens to use. The SWS DCF model values International Bancshares at $139.71 per share, which is well above the recent $66 price and flags the stock as undervalued on future cash flows rather than current earnings.
DCF work can be sensitive to the inputs. A simple P/E snapshot, in contrast, leans on recent profit power instead of long range assumptions. When those two anchors point to similar upside, the real question becomes which yardstick you trust more when trading moves to the Texas Stock Exchange.
