Owners and managers of companies of sufficient size are periodically pitched merger and acquisition (M&A) deal proposals—often in excess. As such, investment bankers, groups (such as private equity shops) and related companies, typically within the same industry, provide ideas to decision makers on acquiring another company, merging with a competitor, or being acquired by a financial group or operating company.

What is Accretion/Dilution Analysis?

Accretion/dilution analysis is, in essence, complex words attributed to a simple test, although there is some grunt work required. Basically, accretion/dilution analysis answers the question: "Does the proposed deal increase or decrease the post-transaction earnings per share (EPS)?" This determines the justification for the deal in the first place.

For companies faced with M&A opportunities, many factors need to be considered, including the global impact of the arrangement, likelihood of a quick and painless negotiation process, and compatibility of the merging or acquiring companies. The dealmakers—the front-line workers who spearhead the deals—must address all of these factors in order to successfully broker M&As.

Steps Involved in Accretion / Dilution Analysis

  1. Estimate a pro forma net income for the combined entities.
  2. Include conservative estimates of net income, taking into account prospective operational and financial synergies that are likely to result after the deal is finished. Some groups incorporate the last 12 months (LTM) as well as one- or two-year projections. Others include projected net income only. Regarding prospective synergies, the new company may anticipate higher revenues due to cross-selling of a wider array of product and service offerings, as well as lower costs due to the elimination of redundant functions and manufacturing facilities. (If you're unfamiliar with pro forma net income, refer to Understanding Pro-Forma Earnings.)
  3. Aside from variables that affect the pro-forma net income due to anticipated synergies, the analyst should also account for transaction-related adjustments that may occur, such as higher interest expense if this is a leveraged buyout and debt is used to fund the deal, lower interest income if cash is used to make the purchase, and additional considerations on post-transaction intangible asset amortizations.
  4. Calculate the combined company's new share count.
  5. Tabulate the prospective acquirer's share count. Factor new shares that would be issued to make the purchase—if it's a stock deal.
  6. Check the accuracy of your numbers.
  7. Lest you risk looking dumb in front of the deal team, check your numbers before presenting them. Are you incorporating some professional skepticism on prospective synergies, or is the entire garden laden with beautiful roses?
  8. Divide pro forma net income by pro forma shares to arrive at a pro forma EPS.
  9. Is the pro forma EPS higher than the original EPS? An increase to EPS is regarded as accretion, while a decrease is regarded as dilution. Many on Wall Street typically frown at dilutive transactions. If a deal has a reasonable likelihood of turning accretive from year two and onwards, a proposed business combination may be more palatable.

The Bottom Line

Accretion/dilution analysis is often seen as a proxy for whether or not a contemplated deal creates or destroys shareholder value. For instance, if the combined entity has better manufacturing capabilities and more diverse offerings, it may take more than a couple of years to fully integrate both operations to leverage and realize efficiencies, and for marketing to convey the message.

This type of analysis is not a composite of the complete picture, nor does it contemplate on how a newly-combined entity operates, adjusts, or takes advantage of opportunities years down the road.
