The Impact of Interest Rates on Middle-Market Mergers and Acquisitions (M&A)

By John Rogers, on May 21st, 2025

Interest rates play a pivotal role in shaping the landscape of M&A activity. As they influence the cost of capital, debt availability, and market dynamics, fluctuations in interest rates can either accelerate or decelerate deal-making and investment strategies in the middle market. Middle market M&A is particularly sensitive to interest rate fluctuations due to its reliance on private equity, debt financing, and the availability of capital. Understanding these impacts is essential for market participants aiming to navigate the complexities of the middle market M&A landscape

Cost of Capital and Valuation

Interest rates directly affect the cost of borrowing for companies and investors. When rates are low, borrowing becomes more affordable, enabling companies to finance acquisitions and expansions with greater ease. This often leads to higher deal activity, as the lower cost of debt increases the potential returns on investment (ROI). Conversely, higher interest rates elevate borrowing costs, which can reduce the attractiveness of debt-financed deals and put downward pressure on valuations. For middle-market businesses, higher capital costs may lead to reduced valuations as buyers adjust their expectations to account for higher financing expenses.

Private Equity: Leveraged Buyouts

Private equity (PE) firms are key players in middle-market M&A, some of whom employ leveraged buyout (LBO) strategies to acquire target companies. LBOs rely heavily on debt, and higher interest rates can erode the financial viability of such deals by increasing the cost of servicing debt. Rising rates may also compress internal rates of return (IRR), making PE firms more cautious in their investment strategies. Moreover, refinancing existing debt becomes more expensive, impacting portfolio company performance and exit strategies. Conversely, in a low-interest-rate environment, PE firms can secure inexpensive financing to support LBOs, boosting cash flow and equity returns.

Market Dynamics and Deal Confidence

Interest rates also influence market confidence and deal-making sentiment. Low rates often foster optimism, as they signal a favorable monetary policy environment and economic growth prospects. This encourages companies and investors to pursue strategic transactions and investments. However, in a rising rate environment, market uncertainty can dampen deal confidence, leading to fewer transactions or longer negotiation timelines. Investment bankers (and sellers) may hesitate to bring businesses to market if valuations are expected to decline, while buyers might adopt a more conservative approach to pricing and deal terms. This dynamic can create a temporary lull in middle-market M&A activity as stakeholders adjust to new economic conditions.

Debt Financing and Capital Structure

Debt financing is a cornerstone of many M&A transactions, particularly in the middle market. Low rates encourage the use of debt in deal structures, as companies seek to capitalize on inexpensive borrowing. This often results in highly leveraged transactions, where debt makes up a substantial portion of the capital stack. Conversely, rising interest rates can complicate capital structures by increasing the cost of debt, forcing buyers to turn to creative deal structures to bridge the valuation gap. Some of these deal structures include seller financing, where the seller holds a note issued by the buyer and typically receives monthly payments; earnouts, which allow the seller to receive additional transaction consideration if certain financial metrics are met after the business is sold; and/or rollover equity, where the seller retains a portion of ownership in the business after the transaction. Navigating these challenges requires innovative solutions and a keen understanding of market conditions and alternative deal structures.

Opportunities in a Higher Interest Rate Environment

While rising interest rates pose challenges, they also present opportunities for strategic buyers. Unlike private equity buyers, which almost always utilize debt financing when acquiring companies, strategic buyers with ample cash reserves may choose to forgo debt financing altogether. Because of this, strategic buyers with ample cash reserves may find themselves in a competitive position compared to private equity buyers that need to access capital markets. Higher interest rates environments generally lead to lower valuation multiples, potentially allowing strategic buyers to acquire businesses less expensively compared to lower interest rate environments. In other words, strategic buyers with ample cash reserves may actually benefit from transaction pricing pressure in higher interest rate environments.

Investment bankers play a crucial role in helping clients adapt to changing interest rate environments. By providing tailored advice on capital structure, valuation expectations, and deal structuring, investment bankers enable their clients to identify opportunities and mitigate risks.

Final Thoughts

The impact of interest rates on middle-market M&A is multifaceted, influencing everything from the cost of capital to market dynamics and deal structures. While low interest rates typically spur deal-making and enhance valuations, rising rates introduce challenges that require strategic adjustments. However, opportunities remain for strategic and well-prepared investors who can adapt to these changes.

Staying attuned to interest rate trends is essential for executing successful transactions and maintaining competitiveness. By proactively addressing the implications of interest rate changes, market participants can navigate the complexities of the financial landscape and capitalize on emerging opportunities.
