Stellus Capital Investment Corporation Reports Preliminary Results for its Second Fiscal Quarter Ended June 30, 2026

Stellus Capital Investment Corporation Schedules Second Quarter 2026 Financial Results Conference Call

Houston, Texas, July 29, 2026 (PR Newswire) – Stellus Capital Investment Corporation (NYSE:SCM) (“Stellus”, “we”, or the “Company”) today announced preliminary financial results for its second quarter ended June 30, 2026.

Robert T. Ladd, Chief Executive Officer of Stellus, stated, “I am pleased to report operating results for the quarter ended June 30, 2026, including a preliminary estimate of U.S. GAAP net investment income of between $0.25 and $0.27 per share. During the quarter, we funded approximately $18 million of investments and received approximately $49 million of repayments, resulting in a total portfolio between $965 million and $975 million at fair value.”

Preliminary Estimates of Second Quarter 2026 Results

The Company’s preliminary estimate of second quarter 2026 net investment income (“NII”) is $0.25 to $0.27 per share. The Company’s preliminary estimate of net asset value (“NAV”) per share as of June 30, 2026, is $12.76 to $12.84, representing an increase of $0.22 to $0.30 per share, or 1.8% to 2.4%, from the NAV per share of $12.54 as of March 31, 2026. The estimated NAV per share increase is primarily due to the net fair value appreciation on the investment portfolio and the accretive impact of equity repurchases, partially offset by dividends per share paid in the second quarter in excess of NII per share. As a result, the Company estimates that it generated an annualized return on equity of more than 17% for the second quarter of 2026. The Company estimates that investments on non-accrual status comprised 5.4% of the total investment portfolio at fair value and 8.5% at cost as of June 30, 2026. During the quarter, loans to one portfolio company were returned to accrual status, and there were no additions to non-accrual status.

Notable Events in Second Quarter 2026

On July 14, 2026, we received a license from the U.S. Small Business Administration (“SBA”) for our third SBIC which allows us to contribute $125 million of equity and draw up to $250 million of SBA-guaranteed debentures, subject to the increased family of funds limit of $475 million across all of our SBIC subsidiaries and applicable SBA regulations and policies. Our partnership with the SBA is an important part of our capital structure and provides long-term, low-cost growth capital for our business.

Pursuant to the Company's share repurchase program approved by its Board of Directors, during the second quarter of 2026, the Company repurchased 274,343 shares of its common stock at a weighted average price of $8.88 per share, representing an aggregate investment of approximately $2.4 million. As of June 30, 2026, approximately $17.6 million remained available for repurchases under the Company's authorized $20.0 million share repurchase program. The Company currently expects the repurchase program to remain in effect until the earlier of March 2, 2027 or the repurchase of $20.0 million of the Company's outstanding common stock.
