Materiality thesis: One meaningful development this run, resulting in one register status advance. A long-running Southeast Missouri bank merger completed its systems conversion, closing out one of the register's oldest open watch-list items. No new charter applicants, no new credit-union action, no new bank failure.
Classification: STATUS CHANGED — advance from Approved (Conversion in Progress) to Completed.

Fact. First State Bank & Trust's systems conversion of Senath State Bank was completed August 10, 2026, per the institution's own merger-transition materials. Senath customers' accounts, routing number, and digital-banking access moved to First State that day. Senath State Bank's standalone website now redirects to First State Bank & Trust's site, consistent with the target's independent identity being retired.
Interpretation. This closes out one of CBSI's longest-open watch-list items — the deal was announced in March 2026, approved in June, and has now completed its full lifecycle through systems conversion. It's a straightforward in-market consolidation (both institutions already operate in the same Southeast Missouri footprint) rather than a geographic expansion play — a cost/scale rationale, not a market-entry one. No new strategic theme advanced; this is routine community-bank M&A completing on schedule.
How confident. Moderate-high. The completion date comes from the issuer's own timeline page rather than a dedicated announcement confirming completion in the past tense, so it is a same-source, date-passed inference — corroborated independently by the target's website now redirecting to the acquirer's site (a standard signal that the acquired institution's separate identity has been retired). No FDIC merger-consummation record was independently checked this run; if one becomes available it should supersede this citation.
What directors should watch. None — this is a completed, non-recurring lifecycle close for a small in-market deal.

Known limitation carried forward: the completion evidence is a target-date-passed inference plus a site-redirect signal, not an explicit dated "conversion complete" release. Flagged in the register Notes and preserved here rather than smoothed over. Supersede with an FDIC merger-consummation record if one appears.
