The fifteen-year-long high-stakes bet on the software industry by private markets is now confronting a comprehensive reckoning. Over $330 billion in high-yield bonds, leveraged loans, and business development company (BDC) related software and technology debt is set to mature by 2028, just as artificial intelligence disrupts traditional SaaS business models. This dual threat has been termed the "SaaSpocalypse" by the market. According to reports, some private credit funds have already started refusing financing to software borrowers, and several planned private equity sales of software companies have stalled.

Investor anxiety is leaving clear marks on the market. Significant capital is flowing towards redemption gates of direct lending funds, forcing some managers to impose withdrawal restrictions on semi-liquid products. In the leveraged loan market, the premium pricing long enjoyed by tech loans has completely collapsed this year. Bruce Richards, Chairman of Marathon Asset Management LP, stated this week that default rates in software direct lending could reach as high as 15% in the coming years.

The software wager represents a highly concentrated risk in private markets. Over the past fifteen years, private market managers poured hundreds of billions of dollars into the software sector, betting on the high growth and stable cash flows promised by SaaS business models. This concentration intensified over time—data shows that software and tech services recently accounted for nearly half of all private equity deals, far exceeding any other industry.

This concentration was historically justified by excess returns. Funds focused on tech investments consistently outperformed the market in terms of internal rate of return (IRR). However, as more capital flooded into the same space, this premium has narrowed significantly in recent years.

The era of low interest rates accelerated this gamble. The easy monetary policy following the pandemic fueled a surge in software asset valuations, with 2021 setting a record for private equity and venture capital M&A activity in the sector. Yet, the lack of interest rate hedging has led to a sharp increase in borrowing costs, casting doubt on the validity of those paper valuations.

A "debt maturity wall" is fast approaching, posing a concentrated stress test for 2028. In that year alone, over $140 billion of tech company debt is scheduled to mature, with related companies potentially seeking refinancing as early as the second half of this year. Analysts at Citigroup pointed out that a significant portion of this wall consists of loans originated during the era of cheap pandemic-era money. They noted that one-third of these loans still carry credit dates from 2021, indicating issuers haven't demonstrated capital market financing capability for years. The average price for loans issued in 2021 and maturing in 2028 is $83.40, a clear signal of stress.

For BDCs, the pressure arrives sooner. Over $31 billion of debt related to the software industry is due this year, testing these lenders that primarily serve small and medium-sized enterprises. An advisor noted that rising credit costs mean "higher interest expenses will severely impact" weaker companies, potentially forcing them to seek additional capital injections from their equity sponsors.

Leveraged loan prices serve as a leading indicator for private credit stress. Declining prices for software-related leveraged loans often foreshadow future interest coverage problems for private credit borrowers. Currently, these prices are trending downwards. Meanwhile, private credit book value adjustments typically lag public market moves, suggesting the full extent of the pressure may not yet be visible.

A debt instrument known as "Payment-in-Kind" (PIK) is also raising regulatory concerns. PIK allows borrowers to defer interest payments until debt maturity, and private credit firms are accused of using it to mask portfolio weaknesses. One advisory firm uses the accumulation of "bad PIK" during a loan's life as a proxy for actual default rates in private credit. They estimate that approximately 6.4% of direct lending borrowers had bad PIK in the fourth quarter, up from just 2.5% at the end of 2021. The loan-to-value (LTV) ratios for these borrowers are also rising, further indicating accumulating stress.

There is significant disagreement regarding the ultimate severity of the crisis. While Marathon's Bruce Richards predicts a 15% default rate for software direct lending, a co-head at Goldman Sachs Asset Management holds a more optimistic view. He argues that although software and tech exposures can reach 30% in some private credit portfolios, these loans are often senior in the capital structure, offering some protection during restructuring.

Researchers from MSCI highlight a structural risk: "Software borrowers from private credit funds have higher leverage ratios and are more dependent on future growth expectations than borrowers in other sectors, making them more vulnerable to negative shocks."

Regarding potential resolutions, an advisor outlined two possible paths: some private equity managers will attempt to sell portfolio companies, hoping to fetch prices high enough to repay debt; in other cases, "private credit and private equity will choose to extend and amend, with lenders getting higher pricing and companies buying time to adjust." However, he also noted that the long-standing "symbiotic relationship" between direct lenders and private equity is fraying, as equity sponsors, seeing no further value, are beginning to refuse additional funding for their portfolio companies.
