Prime Numbers: Stop obsessing about earnings accretion

When boards, investors, and executives consider potential acquisitions, talk often turns to whether earnings per share (EPS) will rise or fall because of the deal and, in turn, how the stock market may react. This obsession with EPS has to stop; there is no correlation between whether a deal is accretive or dilutive and the market’s perceptions of it. Regardless of whether EPS is expected to be greater, smaller, or the same two years after the deal, the market’s reaction is likely to be the same one month and then one year after announcement.

Consider this hypothetical example: A company pays $500 million to acquire a business priced at $400 million, resulting in $100 million of acquisition premium. The deal doesn’t create any immediate operating improvements. As a result, the acquirer ends up paying $500 million for an entity that is worth only $400 million. The deal appears to be dilutive. But is it? If this were an all-cash deal (or even an all-stock deal), the next year’s EPS would increase and the deal would be accretive—the result of mathematics rather than of any value created.1

All this attention on EPS is misplaced. Instead, acquirers and the market should focus on deal execution: What is the integration plan? Is there a clear narrative about the acquisition? The bottom line is ensuring that the value of synergies from the deal exceeds the premium paid.
