Memos from Howard Marks: More on Repealing the Laws of EconomicsAgainst a backdrop of economic and geopolitical uncertainty, private equity deal activity remains selective, with persistent scrutiny around valuation as investors adapt to a higher cost of capital and extended holding periods.
Against a backdrop of economic and geopolitical uncertainty, private equity deal activity remains selective, with persistent scrutiny around valuation as investors adapt to a higher cost of capital and extended holding periods. However, looking forward, we believe private equity managers will need to heighten their focus on operational improvements and shift from benefiting from the tailwind of multiple expansion in favor of the gritty hard work of margin expansion.

For years, private equity managers have benefited from multiple expansion, enabled by an era of near-zero interest rates. In essence, multiple expansion occurs when investors are willing to pay more for each dollar of a company’s earnings—akin to rising P/E ratios seen in public companies over recent years.
Today, however, higher interest rates are putting downward pressure on valuation multiples, thus private equity value creation will increasingly depend on margin expansion, in other words, improving a company’s profitability by increasing earnings relative to revenue—i.e., generating more profit per dollar of sales.
Historically underemphasized, this factor contributed just 10 basis points to median value creation over the past decade, signaling meaningful room for improvement in a higher interest rate environment.

Despite this, margin expansion is still important for top-quartile private equity deals. As shown below, margin expansion accounted for 15% of the value creation drivers for the top private equity global buyout deals.

These outperforming investments have generated a significant share of their value creation through operational improvements and enhanced profitability. It also is important to note that top-quartile deals also commanded higher exit multiples—highlighting that investors are willing to pay a premium for businesses that demonstrate operational margin expansion.
The Art of Expanding Margins
Unlike multiple expansion, which is highly sensitive to market cycles and macroeconomic uncertainty, profit margins are more controllable. Private equity managers can create value—and build resilience—by expanding margins through operational expertise. This approach positions portfolio companies to perform more consistently, regardless of the prevailing interest rate environment or trade policy shifts (See the chart below).
Illustrative analysis assumes a 20% tariff applied to 50% of cost of goods sold (COGS), resulting in a 10% increase in total COGS and an 8 percentage point reduction in gross margin (from 20% to 12%), assuming no cost pass-through. Gross margin recovery scenarios reflect operational efficiency gains of 5%, 8% and 10%, based on Bain & Company benchmarks for supply chain and cost transformation programs. Recovery percentages represent regained margin points relative to the original 20% baseline. All figures are illustrative and rounded for simplicity.

Summing Up
With valuation multiples under pressure and elevated interest rates likely to remain a structural feature, private equity managers must rely less on market-driven tailwinds and more on what they can directly control: operations. The ability to drive returns through margin expansion—improving efficiency, optimizing cost structures, and unlocking value at the portfolio company level—has become a critical differentiator.
This operational approach not only drives performance but also builds resilience amid uncertainty, enabling managers to create value independent of market cycles or macro conditions. In the new era of structurally higher rates, the capacity to generate returns through margin expansion may well define the next generation of top-performing managers.

A WORD ABOUT RISK
As an asset class, private credit comprises a large variety of different debt instruments. While each has its own risk and return profile, private credit assets generally have increased risk of default, due to their typical opportunistic focus on companies with limited funding options, in comparison with their public equivalents.
Because private credit usually involves lending to below-investment-grade or non-rated issuers, yield on private credit assets is increased in return for taking on increased risk.
Investments in real estate-related instruments may be affected by economic, legal or environmental factors that affect property values, rents or occupancies of real estate. Infrastructure companies may be subject to a variety of factors that may adversely affect their business, including high interest costs, high leverage, regulation costs, economic slowdown, surplus capacity, increased competition, lack of fuel availability and energy conservation policies.
Alternative investments often are speculative and include a high degree of risk. Investors could lose all or a substantial amount of their investment. High-yield bonds are subject to interest rate risk. When interest rates rise, bond prices fall; generally, the longer a bond’s maturity, the more sensitive it is to this risk. Yields are subject to change with economic conditions. Yield is only one factor that should be considered when making an investment decision.
