Publicly listed business development companies, the portfolio-facing segment of the private credit industry, have collectively recorded a swing into losses, according to a standardized review of balance sheet metrics compiled from S&P Global Market Intelligence. The move into negative territory in the first quarter of 2026 reflects larger writedowns on loan portfolios and increasing funding costs across a sample of 53 BDCs.
BDCs operate by extending credit to mid-sized businesses and generating income primarily from interest payments on those loans. The private credit sector overall is estimated at about $3.5 trillion; listed BDCs offer the most visible window into the wider market.
Under customary industry reporting, managers and markets often focus on net investment income - a metric that excludes unrealized changes in the value of loans. S&P Global Market Intelligence, however, applies a standardized approach that converts that flow measure into a bottom-line profit figure by reintegrating debt costs and valuation adjustments, drawing on third-party appraisals or managers' own valuations where available. Using that standardized bottom-line metric, the 53 BDCs in the review shifted to an aggregate net loss for the first time in the period available for comparison, driven principally by writedowns of assets including loans to software companies.
S&P's figures show the group's average profit fell to negative $7.6 million in Q1 2026, down from average profits of $26 million a year earlier. Likewise, 28 of the 53 BDCs were loss-making on that standardized measure in Q1 2026, compared with 12 a year earlier and 10 in 2024. Those counts and averages were reviewed and affirmed by multiple external reviewers and the S&P platform.
Analysts and industry observers say the pattern of broader writedowns signals a re-valuation of loan books across the sector. "It is a sign. Fund managers are marking assets down more widely than we've seen in this cycle," said Leyla Kunimoto, founder of Accredited Investor Insights, who reviewed the standardized results. "This will translate into lower returns for investors." Kunimoto added that the data show the entire universe of these funds is repricing loans.
Supporters of the BDC structure note that listed funds provide comparatively transparent reporting on portfolio assets, valuation approaches, leverage and performance. "BDCs are important in providing capital for middle-market businesses to grow," said Jiří Król, global head of the Alternative Credit Council. "Investors in BDCs benefit from standardised and transparent reporting, particularly around portfolio assets, valuation, leverage and performance. This transparency is much higher than that of bank balance sheets."
Funding costs and non-cash income
S&P data show interest expense across these BDCs has risen by roughly one-fifth over the past two years, increasing from an average near $23 million to about $28 million. That rise in cost of funds has coincided with higher utilization of financing techniques that bolster reported income but do not necessarily reflect immediate cash inflows.
Payment-in-kind (PIK) income - where interest is paid by issuing additional debt rather than cash - has become a larger component of reported interest and dividend income. Industry data indicate PIK accounted for an average of 8.1% of BDCs' interest and dividend income in 2025, up from 7.7% in 2024 and roughly double rates seen before 2020, according to Fitch Ratings. PIK boosts headline income but adds principal to borrowers' balance sheets and ultimately to the lenders' holdings.
"While PIK income may ultimately be earned by investors, it is non-cash income and can be an early indicator of eroding credit quality," said Steve Novakovic, managing director of Educational Programs at the CAIA Association, in comments reviewing the standardized analysis.
Off-balance-sheet borrowing and disclosure gaps
BDCs have also been expanding borrowing through special purpose vehicles and joint ventures - structures that often keep debt outside the BDCs' headline balance sheets and thus outside regulatory safety metrics. A focused review of earnings reports using a financial data platform found that only 14 of the reviewed BDCs published complete data on their joint ventures. At those 14 funds, off-balance-sheet borrowing rose sharply.
There is no indication regulatory rules have been violated. Nonetheless, the complexity of these debt structures can mean material financing is not disclosed in a uniform or fully transparent way. When the additional borrowing reported through joint ventures and similar vehicles is added back onto the balance sheets of those 14 funds, overall borrowing grew by 80% across 2025 and by a further 14% in the first quarter of 2026, based on the standardized calculations.
Writedowns and individual fund moves
Certain funds disclosed significant markdowns to existing loans. One large fund recorded a $490 million markdown in the first quarter - its largest since inception - while simultaneously reporting a $100 million realised gain on investments in the same period. Another listed manager reported realised losses of $195 million in Q1, its biggest since 2024 and its second-highest on record. A third BDC logged more than $12 million in losses in the same quarter, the largest hit for that company since 2020, according to S&P's dataset.
Broader market moves reflect these pressures: the S&P BDC index has fallen 8.4% since the start of 2026, while the S&P 500 has risen by nearly 9% over the same span. The companies involved did not provide comments for this analysis.
Overall, the standardized bottom-line view highlights an inflection point for publicly traded private credit vehicles. Rising funding costs, increased non-cash income components and heavier use of off-balance-sheet leverage have combined with portfolio writedowns to push the sample into aggregate losses. The results have drawn scrutiny from investors and regulators, and have prompted discussion among market participants about valuation practices and disclosure standards in this segment of the credit market.
