Second Fiscal Quarter 2024 Highlights:

• Portfolio Activity: Invested $15.0 million in one new portfolio company and $29.7 million in existing portfolio companies.

• Portfolio Mix: Secured first lien assets continue to be over 70% of our debt investments, at cost, while the weighted average yield on debt investments was consistent at 14.0%.

• Credit Facility Availability: Increased the committed facility amount by $10.0 million to $243.7 million and ended the quarter with availability in excess of $100 million.

Second Fiscal Quarter 2024 Results:

Total investment income increased by $0.8 million, or 3.3%, for the quarter ended March 31, 2024, compared to the prior quarter ended December 31, 2023, driven by a $0.7 million increase in interest income. The increase in interest income was driven by a 3.5% increase in the weighted average principal balance of our interest-bearing investments from $657.6 million during the quarter ended December 31, 2023 to $680.4 million during the quarter ended March 31, 2024.

Total expenses increased by $1.9 million, or 17.1%, quarter over quarter primarily due to a $1.4 million increase in the net base management fee, driven mainly by a decrease in portfolio company fee credits from new deal originations quarter over quarter.

Net investment income for the quarter ended March 31, 2024 was $10.8 million, or $0.25 per share.

The net increase in net assets resulting from operations was $23.6 million, or $0.54 per share, for the quarter ended March 31, 2024, compared to $20.0 million, or $0.46 per share, for the quarter ended December 31, 2023. The current quarter increase was primarily driven by $10.7 million of net unrealized appreciation recognized during the quarter.

Subsequent Events: Subsequent to March 31, 2024, the following significant events occurred:

• Portfolio Activity: In April 2024, we invested $7.3 million in Total Access Elevator, LLC (“Total Access”) through secured first lien debt and equity. We also extended Total Access a $3.0 million line of credit commitment and a $2.5 million delayed draw term loan commitment, both of which were unfunded at close.

• Portfolio Activity: In April 2024, our debt investment in Giving Home Healthcare, LLC (“Giving Home”) paid off at par for net cash proceeds of $29.7 million including a $0.9 million prepayment penalty. We also received a $2.5 million distribution related to our warrant position in Giving Home.

• Portfolio Activity: In May 2024, our debt investment in Gray Matter Systems, LLC paid off at par for net cash proceeds of $14.0 million including a $0.2 million prepayment penalty.

• Reverse Stock Split: On April 4, 2024, we completed a 1-for-2 reverse stock split (the “Reverse Stock Split”) of the Company’s issued and outstanding common stock, par value $0.001 per share (“Common Stock”), by the filing of Articles of Amendment with the State Department of Assessments and Taxation of Maryland pursuant to the Maryland General Corporation Law. The Reverse Stock Split became effective at 4:05 p.m. Eastern Time on April 4, 2024. The Reverse Stock Split was effective for purposes of trading as of the opening of business on the Nasdaq Global Select Market on April 5, 2024.
