IBOC's first leg is the Texas-Mexico border-banking community + commercial franchise — selected aggregate the distinctive Texas + Mexico-cross-border-trade-related banking-focus + multi-decade-Laredo-and-South-Texas-and-border-region positioning. Branch network (~190+ branches) across selected aggregate (a) Laredo (HQ + selectively-dominant Laredo-and-South-Texas-border-banking market-share) — selectively-Laredo is selectively-the largest US-port-of-entry by selected aggregate value-of-trade with Mexico (selectively-~$300-400B+ annual Laredo-Mexico-border-trade with selectively-substantial selectively-Texas-Mexico-trade flowing through selectively-Laredo + selectively-Eagle Pass + selectively-Brownsville-and-other Texas-Mexico ports-of-entry); (b) South Texas (selectively-McAllen + Brownsville + Eagle Pass + Del Rio + selectively-other border + Rio-Grande-Valley markets); (c) Greater Houston, Dallas-Fort-Worth, Austin, San Antonio, selectively-Other Texas + Oklahoma markets.

The Dennis Nixon Founder-CEO + Mexico-Cross-Border-Trade-Banking + Multi-Decade Compounder Thesis

The second deep-dive covers IBOC's Dennis Nixon Founder-CEO + Mexico-cross-border-trade-banking + multi-decade compounder thesis. (a) Founded 1965/1979 by Dennis Nixon: selectively-distinctive multi-decade-Texas-banking entrepreneur + meaningful Laredo-and-South-Texas-border-banking pioneer; selectively-Nixon has multi-decade ~45+ year Founder-and-Insider-controlling Texas-banking executive + founding-family-controlling-equity-and-voting-control providing substantial multi-decade-aligned-strategic-positioning.

Capital Position + Balance Sheet

IBOC runs a strongly-capitalized, dividend-substantial-and-special, conservative balance sheet. Capital ratios: selected aggregate CET1 capital ratio ~14-16% (selectively-substantially-above 7-8% regulatory-minimum + selectively-among-highest US-community-bank), Tier 1 capital ratio ~15-17%, Total capital ratio ~16-18%, Tangible common equity ratio ~9-11%. Credit profile: A-/BBB+ IG-equivalent (operating-bank-subsidiary International Bank of Commerce + selectively-other-IBOC-subsidiaries A-/BBB+ rated reflecting selectively-meaningful substantial-capital + community-bank-credit-loss-experience + Texas + Mexico-cross-border-economic-base). Allowance for credit losses (ACL): selected aggregate ~$110-140M ACL providing selected aggregate ~1.3-1.6% of total-loans coverage — selectively-conservative for Texas-and-Mexico-cross-border community-and-commercial portfolio. CRE-concentration: selectively-Texas-and-border-region-average + selectively-monitored office-market exposure. Liquidity: $1-2B cash + selected aggregate substantial-securities-portfolio + selectively-meaningful FHLB-advance-capacity + Fed-Discount-Window. Regular dividend: regular ~$2.20 per share annual ($0.55/quarter), yielding selected various aggregate ~3-4% on the stock — selectively-consistently-grown with selectively-mid-single-digit-percent annual hikes; comfortably covered by net income at selected aggregate ~50-60% payout ratio. Special dividends: selectively-frequent selectively-substantial special-dividends (selectively-distinctive selectively-cyclical-and-strategic-flexibility capital-return-mechanism providing selectively-aligned-with-Founder-and-Insider-controlling capital-allocation-discipline). Buybacks: modest opportunistic (selectively-Founder-and-Insider-controlling-priority on dividend + special-dividend vs aggressive-buyback). Shares outstanding: selected various aggregate ~62M (selectively-stable with selectively-meaningful Founder + Insider ~25%+ economic-and-voting-control providing substantial multi-decade-aligned-strategic-positioning). The principal balance-sheet considerations are the Mexico-cross-border-trade-credit + USMCA-trade-policy + Texas-economic-cycle, best-in-class efficiency continuity, dividend + special-dividend continuity, Founder-and-Insider-controlling capital-allocation-and-governance discipline, selective M&A optionality, and selected aggregate Dennis Nixon multi-decade-Founder-CEO succession + selectively-emerging-multi-decade-leadership transition planning.
