What it means
There is no official line that separates a mega deal from an ordinary large deal, and market commentators draw it in slightly different places. The label is used for the very largest acquisitions, mergers and takeovers, where the combined value runs to many billions.
Such deals usually involve household-name companies and take months or years to complete. A mega deal needs a large cast of advisers.
Investment banks value the target and arrange the funding, law firms handle contracts and competition filings, and accountants carry out due diligence, the detailed check of the target's books. Fees for a deal of this size can run to many millions of dollars.
Funding often combines shares and debt. The buyer may pay with its own shares, with cash raised from bond markets and bank loans, or with a mix, depending on its credit rating and share price.
Heavy borrowing is common, so the combined company's leverage, meaning how much debt it carries, is a key concern for lenders and rating agencies. Regulators examine mega deals closely because combining two giants can reduce competition.
Authorities in several countries may each need to approve the deal, and they sometimes demand that parts of the business be sold off as a condition. This regulatory path can add a year or more to the timetable and sometimes kills the deal outright.
Many studies of large acquisitions suggest that the buyer's shareholders often see little or no gain, while the target's shareholders capture a premium. The usual reasons are overpaying, integration difficulties and culture clashes.
That is why analysts look carefully at the synergies, the cost savings and extra revenue the buyer expects, and at whether they are realistic.
In practice
Real-world examples.
Example
Two pharmaceutical companies agree to combine in a deal valued at $40,000,000,000. Both claim that cost savings of $1,500,000,000 a year will result. Regulators require them to sell a few overlapping products before approving the merger.
Example
A large software company acquires a rival for $14,000,000,000 in cash, funded by a bond issue and its own cash reserves. Its credit rating agency places the company on review, as the debt will raise its leverage. The finance team plans to pay down the debt over three years.
Example
A food manufacturer proposes to buy a competitor but is blocked by competition authorities who fear higher prices. The deal costs the buyer tens of millions of dollars in advisory fees with no benefit. A break fee is payable to the target under the agreement.
Formula
Calculation
Deal value = Equity purchase price + Net debt assumed
Offer premium = (Offer price - Unaffected share price) / Unaffected share price
Suppose a buyer offers $60 per share for a target with 150,000,000 shares, and the unaffected price before any rumours was $50. The equity purchase price is 150,000,000 x 60 = $9,000,000,000. If the target also has net debt of $2,500,000,000 that the buyer takes on, the deal value is 9,000,000,000 + 2,500,000,000 = $11,500,000,000. The premium is (60 - 50) / 50 = 0.20, or 20%.Case study
Seen in the real world.
Castlemere Holdings is an illustrative, fictional industrial group that agreed to buy a rival, Tidewater Systems, for $12,000,000,000. The announced premium was 25% over the unaffected price.
The board expected synergies of $600,000,000 a year, but the finance team's review found that only $350,000,000 could be proved from cost data. Capitalised at a multiple of ten, the difference of $250,000,000 a year represented $2,500,000,000 of value that might never materialise.
The board renegotiated the price down by 5%, which saved $600,000,000, and added a clause allowing it to walk away if regulators demanded large disposals. The illustrative lesson is that in a mega deal the premium must be supported by evidence, not enthusiasm. The finance director also noted that the walk-away right gave the board real leverage in later talks, because the other side knew the board had an option.
Watch out
Common mistakes.
- Quoting the equity price as the full deal value, when debt taken on by the buyer is part of the real cost.
- Assuming the announced synergies will be achieved in full, when many are late or never arrive.
- Underestimating the time regulators need, which can add a year or more and change the economics.
Questions
People also ask.
How big is a mega deal?
There is no official threshold, but many commentators use a deal value of around $10,000,000,000 or more. Deal sizes are usually quoted as enterprise value, which includes the debt taken on and not just the price paid for the shares.
Why do buyers pay a premium?
They offer more than the market price to persuade the target's shareholders to sell, and they hope to recover the premium through synergies. The premium is usually the largest single component of the extra cost, so shareholders and analysts scrutinise it closely.
What is a break fee?
It is a payment agreed in advance that a party must make to the other if the deal collapses for specified reasons. The amount is often a small percentage of the deal value, but on a transaction of this size it can still reach hundreds of millions of dollars.
