Rhea-AI Filing Summary

Security Midwest Bancorp, Inc. notified the SEC that it cannot file its Annual Report on Form 10-K for the year ended December 31, 2025 by the prescribed due date of March 31, 2026 and expects to file within the 15‑calendar‑day extension allowed under Rule 12b-25.

The company says the delay is primarily to allow additional time for pre-filing procedures with its independent registered public accounting firm. The company expects to report net income of approximately $299,000 for 2025 versus $683,000 for 2024, and discloses a $998,000 non‑interest expense tied to withdrawal from its defined benefit pension plan for 2025.

Insights

Delay appears procedural; main driver is a one-time pension expense.

The 12b-25 notice indicates the filing delay stems from completing pre-filing procedures with the independent auditors rather than an unresolved accounting controversy. The filing invokes the 15‑day extension permitted by Rule 12b-25.

Separately, the company quantifies an unusual $998,000 expense from withdrawing its defined benefit pension plan; that one-time charge materially reduced 2025 net income to about $299,000. Subsequent disclosures in the Form 10-K will be needed to confirm cash, liquidity, and any footnote detail supporting the pension charge.

Form 12b-25 regulatory
"Form 12b-25 NOTIFICATION OF LATE FILING SEC File Number"
Form 12b-25 is a notice a publicly traded company files with the U.S. Securities and Exchange Commission when it cannot deliver a required periodic report (like a quarterly or annual financial report) on time. It explains the reason for the delay and gives the company a short, temporary window to finish the report without being marked as delinquent; investors watch it because late filings can signal accounting, operational, or control issues that may affect a company’s reliability and stock risk, much like a missed homework deadline can raise concerns about a student’s preparedness.
Rule 12b-25 regulatory
"as permitted by Rule 12b-25 of the Securities Exchange Act"
Rule 12b-25 is an SEC filing provision that lets a company notify regulators and the public that it cannot file a required periodic report (like a quarterly or annual report) on time and explains the reason for the delay. For investors, the notice is a formal heads-up that financial information will arrive late—similar to a company calling to say it will be late turning in homework—so it signals increased uncertainty and may affect trading and risk assessments until the filing is available.
defined benefit pension plan financial
"withdrawal from our defined benefit pension plan, resulting in expense of $998,000"
A defined benefit pension plan is a retirement program that promises participants a specific monthly payment in retirement, usually based on salary and years worked, with the employer responsible for funding and making up any shortfall. Think of it as the company guaranteeing a steady paycheck in retirement while handling the investments and risks. Investors care because shortfalls become long-term liabilities that can require large cash contributions, affect profitability and borrowing costs, and add uncertainty to a company’s financial health.
