Exhibit 99.1

To Our Valued Shareholders,

We are sharing important information regarding the dividend payment schedule following the successful merger of Mifflinburg Bancorp, Inc. and Northumberland Bancorp under the name Steele Bancorp, Inc., now trading under the stock symbol STLE.

As you may know, historically, the shareholders of Mifflinburg Bancorp, Inc. received semi-annual dividend payments in June and December, while Northumberland Bancorp shareholders received quarterly dividend payments in March, June, September, and December.

Steele Bancorp, Inc. has adopted and will continue the semi-annual June and December dividend payment schedule traditionally used by Mifflinburg Bancorp, Inc. For former Northumberland Bancorp shareholders this means that the four March, June, September, and December quarterly dividend payments they traditionally received will be consolidated into two June and December semi-annual dividend payments. This approach allows Steele Bancorp, Inc. to effectively complete the integration of the merger while aligning with the longstanding tradition of Mifflinburg Bancorp, Inc., which has paid dividends for an exceptional 153 consecutive years; underscoring a deep commitment to shareholder value and financial consistency.

Below is a summary of Mifflinburg Bancorp, Inc.’s annual dividend over the past few years:

●

2020: $1.25 per share

●

2021: $1.31 per share

●

2022: $1.37 per share

●

2023: $1.41 per share

●

2024: $1.45 per share

●
