On March 23, 2018, the Consolidated Appropriations Act of 2018, which includes the Small Business Credit Availability Act (the “Act”), was signed into law. The Act amends the Investment Company Act of 1940, as amended (the “1940 Act”) to permit a business development company (a “BDC”) to reduce the required minimum asset coverage ratio applicable to it from 200% to 150%, subject to certain requirements described therein.

On August 2, 2018, the board of directors (the “Board”) of Solar Capital Ltd. (the “Company”), including a “required majority” (as such term is defined in Section 57(o) of the 1940 Act) of the Board, approved the application of the modified asset coverage requirements set forth in Section 61(a)(2) of the 1940 Act, as amended by the Act. As a result, the Company’s asset coverage requirements for senior securities will automatically be changed from 200% to 150%, effective August 2, 2019.

On the same day, the Board recommended the submission of a proposal for stockholders (the Proposal”) to approve the application of the 150% minimum asset coverage ratio to the Company at the Company’s 2018 Annual Meeting of Stockholders (the “Meeting”). If the stockholder proposal is approved by the required votes of the Company’s stockholders at the Meeting, the Company would become subject to the 150% minimum asset coverage ratio the day after such stockholder approval instead of August 2, 2019.

On August 6, 2018, the Company issued a press release regarding the foregoing. The press release, which is incorporated herein by reference, is included as Exhibit 99.1 and may be deemed soliciting material pursuant to Rule 14a-12 under the Securities Exchange Act of 1934, as amended.

In connection with the Meeting, the Company plans to file with the SEC and mail to its shareholders a proxy statement on Schedule 14A (the “Proxy Statement”). The Proxy Statement will contain important information about the Proposal and related matters. Investors and security holders are urged to read the Proxy Statement, as well as any amendments and supplements thereto, carefully and in its entirety when it becomes available because it will contain important information about the Proposal and related matters. Investors and security holders will be able to obtain the Proxy Statement and other documents filed with the SEC by the Company, free of charge, from the SEC’s website at www.sec.gov and from the Company’s website at www.solarcapltd.com. The Company and its directors and executive officers may be deemed to be participants in the solicitation of proxies from the shareholders of the Company’s common stock with respect to the Proposal. Information regarding ownership of the Company’s common stock by the Company’s directors and executive officers will be available in the Proxy Statement.
