(Name) (Area Code) (Telephone Number)

(2)Have all other periodic reports required under Section 13 or 15(d) of the Securities Exchange Act of 1934 or Section 30 of the Investment Company Act of 1940 during the preceding 12 months or for such shorter period that the registrant was required to file such report(s) been filed? If answer is no, identify report(s).

☒Yes ☐ No

(3)Is it anticipated that any significant change in results of operations from the corresponding period for the last fiscal year will be reflected by the earnings statements to be included in the subject report or portion thereof?

☒Yes ☐ No

If so, attach an explanation of the anticipated change, both narratively and quantitatively, and, if appropriate, state the reasons why a reasonable estimate of the results cannot be made.

The following are the anticipated changes in results of operations for the three months ended March 31, 2026 as compared to the three months ended March 31, 2025:

Net interest income is expected to decrease by approximately $0.2 million, or 4.9%, to $3.6 million for the three months ended March 31, 2026 from $3.7 million for the comparable 2025 period.

Net interest (loss) income after provision for credit losses related to loans held for investment and changes in valuation allowance related to loans held for sale is expected to decrease by approximately $4.5 million, or 167.7%, to loss of $1.8 million for the three months ended March 31, 2026, compared to income of $2.7 million for the comparable 2025 period.

Total other income is expected to decrease by approximately $0.1 million, or 5.7%, to $1.4 million for the three months ended March 31, 2026, compared to $1.5 million for the comparable 2025 period.

Total operating expenses is expected to increase by approximately $2.4 million, or 73.1%, to $5.7 million for the three months ended March 31, 2026, compared to $3.3 million for the comparable 2025 period.

As a result of the foregoing, the Company expects to report a net loss of approximately $6.1 million for the three months ended March 31, 2026, compared to net income of approximately $0.9 million for the comparable 2025 period. After preferred stock dividends of approximately $1.1 million in each period, net loss attributable to common shareholders is expected to be approximately $7.2 million for the 2026 period, compared to approximately $0.2 million for the comparable 2025 period.

The Company believes that its results contained herein for the three months ended March 31, 2026 are materially correct; however, because management's review is ongoing, there can be no assurance that the financial and accounting information referred to in this filing will not change upon completion of the review and filing of the Form 10-Q. Management's assessment of internal control over financial reporting will include a material weakness upon filing of the Form 10-Q.
