Forward-Looking Statements

This quarterly report on Form 10-Q contains forward-looking statements that involve substantial known and unknown risks, uncertainties and other factors. Undue reliance should not be placed on such statements. These forward-looking statements are not historical facts, but rather are based on current expectations, estimates and projections about the company, current and prospective portfolio investments, the industry, beliefs and assumptions. Words such as “anticipates,” “expects,” “intends,” “plans,” “will,” “may,” “continue,” “believes,” “seeks,” “estimates,” “would,” “could,” “should,” “targets,” “projects,” and variations of these words and similar expressions are intended to identify forward-looking statements. These statements are not guarantees of future performance and are subject to risks, uncertainties and other factors, some of which are beyond control of Kayne Anderson BDC, Inc. (“the Company”) and difficult to predict and could cause actual results to differ materially from those expressed or forecasted in the forward-looking statements, including:

We have based the forward-looking statements included in this report on information available to us on the date of this report. We assume no obligation to update or revise publicly any forward-looking statements, whether as a result of new information, future events or otherwise, except as required by law.
