International Bancshares Corp (IBOC)

Companies that benchmark against IBOC
7 companies name IBOC as a compensation peer

Each company listed discloses IBOC in its own benchmarking peer group, as disclosed in each company's most recent proxy statement within the last two proxy seasons. Two companies are therefore absent by design: one that named IBOC in an earlier year and no longer does, and one whose own most recent disclosure is older than the last two seasons.

Equity transactions since the proxy statement was filed

Every insider equity transaction reported on Form 4 after the 2025 proxy statement — acquisitions, dispositions, exercises, and withholdings — and therefore not reflected in any table in that document.

Disclosed peer group — fiscal year 2025

The compensation peer group as the company disclosed it in its own proxy — the reference set behind the percentile above.

10a

Peer reciprocity

Of the companies International Bancshares Corp names as compensation peers, which name it back in their own disclosed peer groups. A peer set the market reciprocates reads differently from one selected in a single direction.

Reciprocity shown where the peer's own current proxy has been read — each mark is cited in the register to that peer's filing. A dash means the peer's current proxy was read and names no reciprocal group including International Bancshares Corp.

10b

Chief executive pay against the peer group

Most recent fiscal-year chief executive compensation at each disclosed peer, taken from that company's own proxy statement.

Each peer's compensation is from its most recently filed proxy; fiscal years differ by company. Each peer's figures come from its own filings; the subject company is highlighted. Peers whose chief executive compensation is outside our coverage universe are stated as such, never left blank.
