Third Coast pays under eight times earnings for capital-constrained Great Plains

Third Coast is paying about 7.7 times what Great Plains earned in 2025 ^[17]. If first-half 2026 profit is doubled to $34.2 million, the multiple falls to roughly 7.0 ^[18]. Against the balance sheet, the price is about 12.6% of Great Plains' $1.9 billion of assets ^[19]. In a stock deal, a low multiple helps the buyer only to the extent its own shares trade higher. The reported terms do not include Third Coast's share price, the exchange ratio or Great Plains' book value ^[1].

Seven-point-seven times is cheap for a bank whose second-quarter net interest margin was 5.34%, about 2 points above the 3.32% industry average ^[4][22]. Caraway's explanation is capital. Great Plains was primed for more growth but was confronting balance-sheet and capital constraints, he said ^[6]. Caraway said that as Great Plains' customer base evolved, those customers would probably outgrow the bank's capabilities. "Now, with us, they'll be able to continue to ride along with those same customers as they get bigger," he said ^[7]. The privately held seller trades a constrained balance sheet for a stake in a bank about 4.7 times its size ^[14][20]. Third Coast gets the earnings without spending cash ^[1].

The 14% accretion Third Coast forecasts for 2028 ^[10] can go three ways. In the first, the $17 million of savings arrives ^[9] and the margin holds. The target then looks reachable: the savings equal about 55% of Great Plains' 2025 profit ^[23], though that comparison sets an expense figure against an after-tax one. In the second, the margin slides and lost interest income offsets the savings. Seventeen million dollars is about 89 basis points on $1.9 billion of assets ^[21], so a margin near 4.45% would cancel them ^[24], or rather a slightly lower one, because margin is measured on earning assets, a smaller base than total assets. The third path is new revenue. Caraway said Third Coast's middle-market capabilities should help Great Plains' bankers win more business from commercial clients ^[16]. "We've already identified a few wins potentially," he said ^[11].

I think the price protects Third Coast more than the forecast does. At 7.7 times earnings ^[17], the deal leaves room for some margin compression. Great Plains' 7.97% loan yield is only slightly above Third Coast's, and its 2.34% deposit cost only slightly below ^[5], so the buyer is not taking on a pricing model far from its own. The counter-case is that the 5.34% margin is what makes 7.7 times look cheap ^[4]. If it reverts toward the industry's 3.32%, the multiple on the earnings that remain goes up. Great Plains' quarterly FDIC margin falling toward 4.5% before the expected first-quarter 2027 close ^[2] would show the savings being eaten before the two banks combine.

Piper Sandler analyst Stephen Scouten described the transaction as a "solid" addition for Third Coast. "They add a granular and lower-cost deposit base while expanding in the Dallas-Fort Worth market and adding an Oklahoma presence," he said ^[12]. "Deal terms appear reasonable," Scouten added ^[13]. The idea that this is how regional banks now buy growth in Dallas and Oklahoma City claims more than one transaction can support. The nearest thing to a pattern in the record is Great Plains itself. It entered Texas in 2022 by buying Providence Bancshares in Dallas-Fort Worth ^[14], and it is now selling to a buyer that wants a deeper Dallas footprint ^[2].
