Effective May 7, 2026, the board of directors of the Company (the “Board”) appointed Casey Alexander, age 66, as a director of the Company. Mr. Alexander was a Managing Director with Compass Point Research & Trading from 2016 until 2026. Prior to joining Compass Point in 2016 he was with Ladenburg Thalmann (2015-2016). Before Ladenburg Thalmann Mr. Alexander was the Director of Research, a Special Situations Analyst, and a member of the Gilford Securities Board of Directors (1996-2015). Prior to joining Gilford Securities Inc. Mr. Alexander spent eight years with PaineWebber Inc (1988-1996). During his tenure at PaineWebber, Mr. Alexander filled multiple roles including Head of Over-the-Counter Marketing, Divisional Sales Manager and Branch Manager. Mr. Alexander has a B.S degree in Economics & Business Management with a concentration in Financial Management from Guilford College. The Board believes Mr. Alexander’s leadership experience and extensive experience covering business development companies made him an appropriate and viable candidate as a member of the Board. We expect to appoint Mr. Alexander to the Pricing Committee, Nominating and Corporate Governance Committee, and the Audit Committee.
