Q4 Margin Guided to ~3.80%
Q3 net interest margin fell to 3.70% (3.74% excluding accelerated accretion) from 3.83% in Q2, and CFO McWhorter set ~3.80% as the Q4 starting point while saying he hopes to overperform; September spot margin was 3.85%.
-
Fee Income Guide Raised to ~$5M
Management lifted the quarterly fee income expectation to about $5 million from the prior $4.0-4.5 million range, citing more swap and loan fees plus a ~$150,000 trailing revenue stream from the factoring business sale.
-
Great Plains Close Set for Feb-Apr 2027
Closing is expected between February 1 and April 1, 2027, subject to shareholder votes on both sides; integration is expected to be easier than Keystone because both banks run on FIS.
-
Q4 Commercial Securitization Planned
A new securitization, the first out of the commercial portfolio, is targeted for December 2026 (possibly slipping to Q1 2027) and is expected to carry more fee income than the Q3 deal, which was roughly a slight net negative.
Analysis · TCBX · Finance
The transcript restates Q3 results already released on October 21, but the Q&A carries the forward numbers that move estimates. Management penciled in a ~3.80% Q4 net interest margin after a surprise 13bp sequential decline to 3.70% (3.74% excluding accelerated accretion), and raised the quarterly fee income run-rate to about $5 million from the prior $4.0-4.5 million guide. On Great Plains, closing is now framed as February 1 to April 1, 2027, pending shareholder votes on both sides, with integration expected to be easier than Keystone because both banks run on FIS. A second securitization is teed up for Q4 — the first out of the commercial portfolio — and is expected to be more fee-rich than the Q3 deal, which was roughly a slight net negative. Q4 merger expense should be modest at roughly $500K-$1M, with Keystone costs already at about $12.5 million of the original $13 million estimate.
