BXSL’s investment portfolio produced $41.4 million of realized losses in the three months ended June 30, versus a $1.2 million gain a year earlier. That single swing helps explain how a secured-lending fund went from $155.0 million of net income to $9.5 million in the comparable three-month period.
The decline was not just a realized-loss problem. Net unrealized losses on investments reached $133.4 million, mainly because the fair value of certain debt investments fell. Diluted earnings per share dropped from $0.68 to $0.04, while diluted shares rose 1.9% to 232.6 million.
BXSL described the realized-loss change this way:
"The decrease was primarily driven by net realized losses on investments of $41.4 million for the three months ended June 30, 2026, compared to $1.2 million for the same period in the prior year, mainly driven by the restructuring of certain debt investments and full or partial sales and repayments of investments."
10-Q, August 6, 2026
In plain English, restructurings, sales, and repayments turned what had been a small gain into a sizable loss. The filing does not break out how much each activity contributed.
The unrealized mark adds a second layer. It does not involve the same realized cash event, but it still flows through the reported result, and it points to a valuation change across parts of the debt book rather than one isolated sale.
BXSL’s cash balance moved far less than its earnings line, slipping from $273.7 million to $267.2 million, a 2.4% decline. That leaves the central tension in the filing: the reported profit nearly disappeared, while the cash balance remained close to its year-earlier level.
Borrowing costs also moved, though not in the same direction as the investment losses. Management said the average principal amount of debt outstanding was higher, partly offset by a lower weighted average interest rate.
"The increase was primarily driven by a higher average principal amount of debt outstanding, partially offset by a lower weighted average interest rate on our borrowings relative to the same period in the prior year."

That disclosure makes the earnings decline harder to reduce to a simple interest-rate explanation. Financing expense reflected more debt, but the sharpest pressure came from losses on investments and lower marks on debt assets.
The stock closed at $23.33 on August 5, down 1.9% that day. BXSL was also among five of six business development company names that crossed the latest activity threshold on August 5, a descriptive sign of attention around the group, not an explanation for BXSL’s result.
The unresolved detail belongs in BXSL’s next 10-Q: the new realized and unrealized investment gains or losses, alongside the cash balance. For now, the filing reports cash close to its year-earlier level alongside investment losses and much lower net income.
BXSL’s 10-Q shows the trade-off plainly: cash stayed nearly flat while investment losses contributed to lower reported profit.
