## Deal Geometries & Synergies

When firms combine, a **merger** fuses two into one, while an **acquisition** is one buying control of another. The economic logic rests on **synergy**: the combined firm must outvalue the separate parts.

$$\text{Synergy} = V_{AB} - (V_A + V_B)$$

Synergies split into **cost savings** (shared logistics, reliable) and **revenue gains** (cross-selling, often over-promised).

| Type | Combines with | Main gain | Main risk |
|---|---|---|---|
| **Horizontal** | Competitor | Scale, share | Antitrust |
| **Vertical** | Supply chain | Secured supply | Rigidity |
| **Conglomerate** | Unrelated | Diversification | Weak synergy |

## Why Deals Fail

The acquirer must pay a **premium** over the target's market price to win control. Value is created for the acquirer only if:

$$\text{Synergy} > \text{Premium}$$

Half of all M&A destroys value due to the **winner's curse**: the most optimistic bidder wins, and overpays.

> **Pitfall:** Treating revenue synergies like cost synergies. Eliminated warehouses are real; cross-selling often evaporates.

> **Rule:** Cap the premium below cold synergy value, and walk away when bidding passes the line.

## Practice questions

5 of this lesson's 14 practice questions, with answers. The full set is in the app.

### 1. Sort each deal by its integration type.

**Answer:**

- Horizontal: Two rival airlines merge
- Vertical: A brewer buys its bottle manufacturer, A streaming service buys a film studio
- Conglomerate: A tobacco group acquires a hotel chain

**Why:** Same stage = horizontal; along the supply chain = vertical; unrelated = conglomerate.

### 2. Match each M&A concept to its meaning.

**Answer:**

- Synergy → Combined value exceeding the sum of the parts
- Premium → Price paid above the target’s market value
- Winner’s curse → The most optimistic bidder overpays
- Due diligence → Pre-deal investigation of the target’s books

**Why:** The four words that decide whether a deal creates or destroys acquirer value.

### 3. Order the stages of a typical acquisition.

**Answer:**

1. Identify a strategic target
2. Conduct due diligence on its books and contracts
3. Negotiate price and announce the offer
4. Obtain shareholder and antitrust approval
5. Integrate operations and capture synergies

**Why:** Target → diligence → deal → approval → integration; most value is won or lost in the last stage, long after the champagne.

### 4. Roughly half of large mergers destroy value for the acquirer's shareholders. Given that the buyers are sophisticated, what best explains the pattern?

A. Acquirers systematically choose the wrong targets in industries they do not understand
B. Synergies are real but take longer than shareholders will wait for
C. Regulators block the profitable mergers and permit only the unprofitable ones
D. The winner's curse plus overconfident synergy estimates

**Answer:** D. The winner's curse plus overconfident synergy estimates

**Why:** Winning a contested auction is evidence you bid the most, and bidding the most is evidence you were the most optimistic, the premium hands the synergies to the seller before they materialise. This is why the deal announcement so often lifts the target's share price and drops the acquirer's.

### 5. If the synergy from a deal is 40M€ and the acquirer pays a 55M€ premium, the acquisition still creates value for the acquirer’s shareholders.

**Answer:** False

**Why:** Value to the acquirer = synergy − premium = $40 - 55 = -15$M€. The target’s shareholders captured the synergy plus 15M€ more.
