The Main Idea
One plus one makes three: this equation is the special alchemy of a merger or an acquisition. The key principle behind buying a company is to create shareholder value over and above that of the sum of the two companies. Two companies together are more valuable than two separate companies - at least, that's the reasoning behind M&A.
This rationale is particularly alluring to companies when times are tough. Strong companies will act to buy other companies to create a more competitive, cost-efficient company. The companies will come together hoping to gain a greater market share or to achieve greater efficiency. Because of these potential benefits, target companies will often agree to be purchased when they know they cannot survive alone.
Distinction between Mergers and Acquisitions
Although they are often uttered in the same breath and used as though they were synonymous, the terms merger and acquisition mean slightly different things. When one company takes over another and clearly established itself as the new owner, the purchase is called an acquisition
In the pure sense of the term, a merger happens when two firms, often of about the same size, agree to go forward as a single new company rather than remain separately owned and operated. This kind of action is more precisely referred to as a "merger of equals." Both companies' stocks are surrendered and new company stock is issued in its place. For example, both Daimler-Benz and Chrysler ceased to exist when the two firms merged, and a new company, DaimlerChrysler, was created.
In practice, however, actual mergers of equals don't happen very often. Usually, one company will buy another and, as part of the deal's terms, simply allow the acquired firm to proclaim that the action is a merger of equals, even if it's technically an acquisition. Being bought out often carries negative connotations, therefore, by describing the deal as a merger, deal makers and top managers try to make the takeover more palatable.
Varieties of Mergers
From the perspective of business structures, there is a whole host of different mergers. Here are a few types, distinguished by the relationship between the two companies that are merging
Horizental Merger
Two companies that are in direct competition and share the same product lines and markets
Vertical Merger
A customer and company or a supplier and company. Think of a cone supplier merging with an ice cream maker.
Market-extension merger - Two companies that sell the same products in different markets.
Product-extension merger - Two companies selling different but related products in the same market.
Acquisitions
In an acquisition, as in some of the merger deals we discuss above, a company can buy another company with cash, stock or a combination of the two. Another possibility, which is common in smaller deals, is for one company to acquire all the assets of another company. Company X buys all of Company Y's assets for cash, which means that Company Y will have only cash (and debt, if they had debt before). Of course, Company Y becomes merely a shell and will eventually liquidate or enter another area of business.
Another type of acquisition is a reverse merger, a deal that enables a private company to get publicly-listed in a relatively short time period. A reverse merger occurs when a private company that has strong prospects and is eager to raise financing buys a publicly-listed shell company, usually one with no business and limited assets. The private company reverse merges into the public company, and together they become an entirely new public corporation with tradable shares. Regardless of their category or structure, all mergers and acquisitions have one common goal: they are all meant to create synergy that makes the value of the combined companies greater than the sum of the two parts. The success of a merger or acquisition depends on whether this synergy is achieved.
Valuation Matters
Naturally, both sides of an M&A deal will have different ideas about the worth of a target company: its seller will tend to value the company at as high of a price as possible, while the buyer will try to get the lowest price that he can. There are, however, many legitimate ways to value companies. The most common method is to look at comparable companies in an industry, but deal makers employ a variety of other methods and tools when assessing a target company. Here are just a few of them:
Comparative Ratios - The following are two examples of the many comparative metrics on which acquiring companies may base their offers:
Price-Earnings Ratio (P/E Ratio) - With the use of this ratio, an acquiring company makes an offer that is a multiple of the earnings of the target company. Looking at the P/E for all the stocks within the same industry group will give the acquiring company good guidance for what the target's P/E multiple should be.
Enterprise-Value-to-Sales Ratio (EV/Sales) - With this ratio, the acquiring company makes an offer as a multiple of the revenues, again, while being aware of the price-to-sales ratio of other companies in the industry.
Replacement Cost - In a few cases, acquisitions are based on the cost of replacing the target company. For simplicity's sake, suppose the value of a company is simply the sum of all its equipment and staffing costs. The acquiring company can literally order the target to sell at that price, or it will create a competitor for the same cost. Naturally, it takes a long time to assemble good management, acquire property and get the right equipment. This method of establishing a price certainly wouldn't make much sense in a service industry where the key assets - people and ideas - are hard to value and develop.
Discounted Cash Flow (DCF) - A key valuation tool in M&A, discounted cash flow analysis determines a company's current value according to its estimated future cash flows. Forecasted free cash flows (net income + depreciation/amortization - capital expenditures - change in working capital) are discounted to a present value using the company's weighted average costs of capital (WACC). Admittedly, DCF is tricky to get right, but few tools can rival this valuation method.
Synergy: The Premium for Potential Success
For the most part, acquiring companies nearly always pay a substantial premium on the stock market value of the companies they buy. The justification for doing so nearly always boils down to the notion of synergy; a merger benefits shareholders when a company's post-merger share price increases by the value of potential synergy. Let's face it, it would be highly unlikely for rational owners to sell if they would benefit more by not selling. That means buyers will need to pay a premium if they hope to acquire the company, regardless of what pre-merger valuation tells them. For sellers, that premium represents their company's future prospects. For buyers, the premium represents part of the post-merger synergy they expect can be achieved. The following equation offers a good way to think about synergy and how to determine whether a deal makes sense. The equation solves for the minimum required synergy: In other words, the success of a merger is measured by whether the value of the buyer is enhanced by the action. However, the practical constraints of mergers, which we discuss in part five, often prevent the expected benefits from being fully achieved. Alas, the synergy promised by deal makers might just fall short.
Conclusion
One size doesn't fit all. Many companies find that the best way to get ahead is to expand ownership boundaries through mergers and acquisitions. For others, separating the public ownership of a subsidiary or business segment offers more advantages. At least in theory, mergers create synergies and economies of scale, expanding operations and cutting costs. Investors can take comfort in the idea that a merger will deliver enhanced market power.
By contrast, de-merged companies often enjoy improved operating performance thanks to redesigned management incentives. Additional capital can fund growth organically or through acquisition. Meanwhile, investors benefit from the improved information flow from de-merged companies. M&A comes in all shapes and sizes, and investors need to consider the complex issues involved in M&A. The most beneficial form of equity structure involves a complete analysis of the costs and benefits associated with the deals
