Introduction
In early 2026, the private equity (PE) landscape shows signs of recovery after years of constrained activity due to elevated interest rates and valuation gaps. Recent reports indicate that U.S. private equity dry powder has declined from record highs around $1.3 trillion in late 2024 to approximately $880 billion by late 2025, as deployment accelerates amid stabilizing rates and improved financing conditions. Large leveraged buyouts (LBOs) have made headlines, such as the $55 billion take-private of Electronic Arts in late 2025, marking one of the largest in history and signaling renewed appetite for aggressive borrowing in high-profile deals.
Leverage levels in buyouts have moderated from pandemic-era peaks. Average overall leverage for large buyouts fell below 6.0x debt-to-EBITDA in Q3 2025, while middle-market deals dropped below 4.5x, according to LSEG LPC data. However, these headline ratios often mask hidden debt elements in PE-backed companies. Hidden debt here refers to off-balance-sheet or under-disclosed obligations that inflate true leverage, including aggressive add-backs to EBITDA, payment-in-kind (PIK) interest structures, NAV (net asset value) loans at the fund level, contingent earn-outs, or layered financing through continuation vehicles and dividend recaps. These mechanisms allow sponsors to push more debt onto portfolio companies without fully reflecting it in standard metrics, creating understated exposure. Regulatory scrutiny, including Bank of England stress tests on private equity and credit announced in late 2025, and concerns over pockets of distress from high-profile defaults, highlight growing awareness of these risks as the sector enters 2026.
Main Predictions for 2026
In 2026, hidden debt in PE-backed companies through leveraged buyouts is expected to persist and evolve, even as overall leverage moderates in response to better financing access. Sponsors will continue using creative structures to maximize returns amid pent-up dry powder deployment and a rebound in M&A activity. Predictions point to increased reliance on NAV financing and continuation vehicles, which introduce fund-level debt backed by portfolio NAV rather than isolated company assets. These tools, already a $100 billion industry in prior years, enable liquidity without full exits but can embed hidden leverage by spreading obligations across holdings.
EBITDA add-backs remain a key source of hidden leverage. In aggressive LBOs, sponsors adjust EBITDA upward for synergies, exceptionals, or non-recurring items, allowing higher reported multiples while masking true debt servicing burdens. Data from 2025 shows leverage ratios appearing manageable at 4.9x to 5x in many cases when using adjusted figures, but unadjusted views reveal higher effective burdens, especially in legacy 2020-2021 vintages refinancing at higher rates. Expect more scrutiny of these adjustments in 2026 as lenders tighten covenants and require clearer EBITDA definitions.
PIK toggles and non-cash interest payments will grow in prevalence for stressed portfolio companies. These allow borrowers to defer cash outflows, preserving liquidity but accruing hidden liabilities that compound over time. Reports indicate nearly 10% of net income in some business development company portfolios came from PIK in recent periods, a trend likely to continue in 2026 for overleveraged assets facing maturity walls.
Refinancing of legacy high-leverage deals will uncover hidden exposures. Many 2021-era LBOs, struck at peak valuations with elevated debt, now face refinancing at stabilized but higher rates, squeezing margins. Predictions suggest a rise in distressed opportunities, with some companies becoming targets for opportunistic buyers rather than growth investors. Middle-market deals, averaging around 4.1x to 4.5x leverage in recent data, may see incremental hidden debt through vendor take-backs or deferred considerations in buy-and-build strategies.
Quantitative trends support gradual escalation. While direct lending and syndicated loans provide more transparent financing, private credit’s dominance in middle-market LBOs (around 85-90% in recent years) allows bespoke terms that can obscure full leverage. Expect notional exposures to rise modestly as deal volumes increase, with sponsor-to-sponsor exits and platform builds layering additional contingent obligations.
Discovery of hidden debt will accelerate through due diligence in exits and refinancings, credit rating pressures, and regulatory probes. Proactive sponsors will disclose more granularly to secure favorable terms, but pockets of opacity will remain in complex structures.
Challenges and Risks
Hidden debt in PE LBOs poses notable risks in 2026. Overleveraged portfolio companies from prior vintages may face covenant breaches or defaults if cash flows weaken under sustained rates, leading to forced restructurings or losses for lenders. NAV loans introduce contagion, as fund-level defaults could impact multiple holdings, unlike traditional ring-fenced company debt.
Investor confidence could erode if revelations of aggressive add-backs or PIK reliance lead to valuation surprises during exits. Systemic stress might emerge if a wave of maturities coincides with economic slowdowns, amplifying losses in private credit portfolios already under scrutiny after 2025 defaults in sectors like auto and parts supply.
Trust erosion is a concern for limited partners wary of continuation vehicles or NAV structures that prioritize sponsor liquidity over transparency. In interconnected portfolios, one hidden exposure materializing could trigger broader sell pressure or LP pullbacks.
Opportunities
Prudent use of leverage and hidden debt tools offers advantages. Creative financing like NAV loans and continuation vehicles provides flexibility, enabling sponsors to hold high-quality assets longer and unlock value without full exits, supporting steady distributions in a maturing market.
Improved transparency through better disclosure of add-backs and structures can build lender and investor trust, leading to lower borrowing costs for well-managed portfolios. Operational focus over financial engineering—emphasizing EBITDA growth via AI, efficiency, and sector specialization—reduces reliance on hidden leverage for returns.
Regulatory evolution and stress testing may drive healthier practices, with sponsors adopting robust governance to access capital more favorably. In 2026, firms demonstrating clear risk management around hidden exposures position themselves for premium valuations and stronger LP relationships.
Strategic flexibility from layered financing supports growth in buy-and-build models, allowing scaled platforms in resilient sectors like technology and healthcare.
Conclusion
In 2026, hidden debt in private equity leveraged buyouts will likely remain embedded through EBITDA adjustments, PIK structures, NAV financing, and legacy refinancing pressures, even as headline leverage moderates with recovering deal activity. While deployment of dry powder accelerates and large LBOs signal confidence, understated obligations create persistent risks of defaults, contagion, and trust issues. Challenges include margin squeezes on older deals and potential systemic stress, yet opportunities exist in transparent structures, operational value creation, and adaptive financing that enhance resilience.
Overall, 2026 represents a transitional phase where hidden debt evolves from aggressive expansion to more disciplined use amid scrutiny and stability. Beyond 2026, expect continued maturation, with greater emphasis on sustainable leverage and disclosure reducing surprise elements while preserving tools for strategic growth. Balanced management—combining creativity with prudence—will separate outperforming sponsors from those facing amplified vulnerabilities in an environment where true exposure increasingly shapes outcomes.
