All forward-looking statements included in this presentation are made only as of the date hereof and are subject to change without notice. Actual outcomes and results could differ materially from those suggested by this presentation due to the impact of many factors beyond the control of New Mountain Finance Corporation (“NMFC”), including those listed in the "Risk Factors" section of our filings with the United States Securities and Exchange Commission (“SEC”). Any such forward-looking statements are made pursuant to the safe harbor provisions available under applicable securities laws and NMFC assumes no obligation to update or revise any such forward-looking statements unless required by law. The following slides contain summaries of certain financial and statistical information about NMFC. The information contained in this presentation is summary information that is intended to be considered in the context of our SEC filings and other public announcements that we may make, by press release or otherwise, from time to time. We undertake no duty or obligation to publicly update or revise the information contained in this presentation unless required by law. In addition, information related to past performance, while helpful as an evaluative tool, is not necessarily indicative of future results, the achievement of which cannot be assured. You should not view the past performance of NMFC, or information about the market, as indicative of NMFC’s future results.

Current performance may be lower or higher than the performance data quoted. This presentation does not constitute an offer to sell or the solicitation of an offer to buy any securities of NMFC. Past performance is not indicative nor a guarantee of future returns, the realization of which is dependent on many factors, many of which are beyond the control of NMFC. There can be no assurances that future dividends will match or exceed historic ones, or that they will be made at all. Net returns give effect to all fees and expenses. Unless otherwise noted, information included herein is presented as of the date indicated on the cover page and may change at any time without notice.
