Corporate earnings have looked surprisingly resilient despite higher interest rates and slowing economic growth. Many companies are still beating profit estimates, and stock prices have responded accordingly. But a closer look at how those earnings are being generated tells a more complicated story.
An increasing share of earnings growth is coming not from stronger business performance, but from shrinking share counts. Buybacks are doing heavy lifting in the background, boosting per-share metrics even as revenue growth cools.
EPS Growth Is Outrunning Revenue
One of the clearest signs of financial engineering is the widening gap between revenue growth and earnings per share growth. Across large U.S. companies, sales growth has slowed compared to the post-pandemic rebound years. Yet per-share profits remain relatively strong.
That divergence is not coming from a sudden surge in productivity. It is coming from math. When companies reduce the number of shares outstanding, each remaining share claims a larger portion of the same profit pool.
This creates the appearance of stronger earnings momentum even when total profits are flat. Investors focused only on EPS may miss the fact that the underlying business is no longer expanding at the same pace.
Buybacks Have Replaced Growth as the Default Strategy
For many mature companies, buybacks have become the primary tool for delivering shareholder returns. Organic growth is harder to achieve in a high-rate, low-demand environment. Large acquisitions are expensive. Capital investment carries uncertain payoffs.
By contrast, repurchasing shares delivers an immediate boost to reported results. It raises EPS, supports stock prices, and often improves executive compensation metrics tied to per-share performance.
This helps explain why buybacks have remained elevated even as economic conditions have tightened. They provide a controllable lever for management at a time when revenue is less predictable.
The Illusion of Earnings Strength
The risk for investors is confusing earnings optics with earnings quality. A company can report rising EPS while its core business stalls.
That matters for valuation. Stocks are priced on future cash flows, not just past per-share profits. If EPS growth is being driven mainly by shrinking share counts rather than expanding operations, future earnings power may be weaker than it appears.
This dynamic also distorts comparisons across time. Earnings today may look stronger relative to previous years, but only because the share base is smaller. The business itself may not be generating meaningfully more cash than before.
Debt Funded Buybacks Raise the Stakes
The financial engineering risk increases when buybacks are funded with borrowed money. During the era of near-zero interest rates, issuing debt to retire equity often made sense. The cost of capital was low, and the boost to EPS was immediate.
With interest rates now much higher, that tradeoff looks different. Debt-financed repurchases increase leverage while reducing flexibility. They also lock companies into higher interest expenses just as growth is slowing.
If profits weaken, those companies may be forced to cut buybacks or raise equity at less favorable prices. What initially looked like disciplined capital allocation can quickly turn into balance sheet strain.
Markets Are Leaning on Buybacks for Support
Buybacks do not just affect individual companies. They shape the entire equity market. When corporations consistently retire shares, the overall supply shrinks. That creates a structural bid for stocks even when investor inflows are uneven.
This helps explain why major indexes have remained resilient through periods of macro uncertainty. Corporate demand has quietly offset some of the pressure from rising bond yields and cautious consumers.
The risk is that this support is cyclical. Buybacks tend to peak when profits are strong and fade when conditions deteriorate. If earnings slow further or credit tightens, that demand can disappear quickly.
At that point, stock prices would be forced to reflect business fundamentals more directly rather than benefiting from mechanical share reduction.
How to Separate Real Growth From Financial Engineering
For investors, the key is not to avoid companies that buy back shares, but to understand what is driving their earnings.
Several signals help distinguish genuine growth from cosmetic improvement.
Revenue trends remain the most important anchor. If EPS is rising while sales are flat, buybacks are likely responsible for much of the gain.
Share count data in quarterly filings shows whether earnings growth is coming from fewer shares rather than higher profits.
Free cash flow reveals whether buybacks are funded by surplus cash or by leverage.
Capital spending trends indicate whether management is investing in future growth or prioritizing short-term metrics.
Together, these measures provide a clearer picture of earnings quality than headline profit numbers alone.
Why This Matters for Valuations
Markets reward consistency. As long as companies can maintain steady EPS growth, valuations remain supported. Buybacks make that easier in the short term.
But over time, valuation depends on the ability to grow the business, not just manage the share count. If economic conditions weaken and buybacks slow, earnings growth may fall faster than investors expect.
That creates downside risk for stocks priced on the assumption that recent profit trends will continue. What looks like durable earnings strength today may prove fragile once financial engineering loses momentum.
