Mergers, acquisitions and corporate restructuring
A merger creates value only if synergy exceeds the premium paid. Restructuring can expand, contract or change ownership, and hostile bids meet takeover defences.
Types of merger
| Type | Meaning | Example |
|---|---|---|
| Horizontal | Firms in the same industry and stage; competitors combine | Vodafone India and Idea Cellular (2018) |
| Vertical | Different stages of the same supply chain (backward or forward) | A steel maker buying an iron-ore mine |
| Conglomerate | Unrelated businesses | A cement firm buying a hotel chain |
| Concentric (congeneric) | Related products, markets or technology, but not the same product | A bank buying an asset-management business |
| Reverse merger | A larger or healthier company merges into a smaller or loss-making one (or an unlisted firm into a listed shell) | ICICI Ltd into ICICI Bank, the bank it had set up (2002) |
| Cross-border | Acquirer and target are in different countries | Tata Steel's acquisition of Corus (2007) |
Forms of corporate restructuring
| Category | Forms |
|---|---|
| Expansion | Merger by absorption, amalgamation into a new company, acquisition of shares or assets, tender offer, joint venture |
| Contraction (sell-offs) | Divestiture (sale of a unit); spin-off (new company, shares given pro rata to existing shareholders); split-off (shareholders swap parent shares for subsidiary shares); split-up (parent broken into several firms); equity carve-out (part of a subsidiary sold to the public) |
| Ownership and control | Leveraged buyout, management buyout, share buy-back, going private |
| Financial | Recapitalisation, debt restructuring, exchange offers |
Where merger value comes from
- Operating synergy: economies of scale and scope, shared distribution and R&D.
- Financial synergy: lower cost of capital, more debt capacity, use of accumulated tax losses (as tax law permits).
- Market power and faster growth than building from scratch.
- Better management of an under-performing target; buying undervalued assets.
- Diversification alone rarely creates value, because shareholders can diversify cheaply themselves.
- Value is destroyed when the premium exceeds the synergy (the winner's curse) or integration fails.
Worked example 1: synergy and the NPV of an acquisition
Firm A is worth ₹500 crore and Firm B ₹200 crore on their own. Combined, they would be worth ₹780 crore. A pays ₹250 crore in cash for B. Who gains, and how much?
- Synergy = 780 − (500 + 200) = ₹80 crore.
- Premium paid = 250 − 200 = ₹50 crore, which goes to B's shareholders.
- NPV to A's shareholders = synergy − premium = 80 − 50 = ₹30 crore.
- Check: A's value after the deal = 780 − 250 = ₹530 crore = 500 + 30.
The ₹80 crore synergy is split: ₹50 crore to B's shareholders and ₹30 crore to A's.
Worked example 2: exchange ratio and EPS
Acquirer A: earnings ₹1 crore, 10 lakh shares, P/E 20. Target B: earnings ₹20 lakh, 4 lakh shares, P/E 12. A pays in its own shares in the ratio of market prices. Find the exchange ratio and the post-merger EPS (no synergy).
- EPS: A = 1,00,00,000 ÷ 10,00,000 = ₹10; B = 20,00,000 ÷ 4,00,000 = ₹5.
- Market price: A = 10 × 20 = ₹200; B = 5 × 12 = ₹60.
- Exchange ratio = 60 ÷ 200 = 0.3 share of A for each share of B; new shares = 4,00,000 × 0.3 = 1,20,000.
- Post-merger EPS = (1,00,00,000 + 20,00,000) ÷ (10,00,000 + 1,20,000) = 1,20,00,000 ÷ 11,20,000 = ₹10.71.
- B's holders: equivalent EPS = 10.71 × 0.3 = ₹3.21, down from ₹5. A's EPS rises because it buys B at a lower P/E (12 vs 20).
- If the ratio were based on EPS (5 ÷ 10 = 0.5), new shares = 2,00,000 and EPS stays ₹10 for both groups.
Exchange ratio 0.3. A's EPS rises to ₹10.71, while B's holders' equivalent EPS falls to ₹3.21.
Takeover tactics and defences
| Tactic | Meaning |
|---|---|
| Bear hug (attack) | An offer so generous that the target's board finds it hard to refuse |
| Dawn raid (attack) | Buying a large stake quickly in the market before the target can react |
| Tender offer (attack) | An offer made directly to shareholders to buy their shares at a stated price |
| Poison pill | Rights that let existing holders buy shares cheaply if a raider crosses a limit, diluting the raider |
| Crown jewel | Selling or locking up the target's most valuable assets |
| Pac-Man | The target makes a counter-bid for the acquirer |
| White knight | A friendly firm is invited to acquire the target instead |
| White squire | A friendly investor buys a large block of shares but not control |
| Golden parachute | Large severance pay for top managers if control changes |
| Greenmail | Buying back the raider's shares at a premium |
| Shark repellents | Charter changes such as a staggered board or supermajority voting |
LBOs, negotiation and Indian rules
- Good LBO targets have stable cash flows, little existing debt and strong assets; the debt is repaid from the target's cash flows. Tata Tea's purchase of Tetley (2000) is often cited as the first leveraged buyout by an Indian company.
- Negotiation range: the seller's floor is the target's standalone value; the buyer's ceiling is standalone value plus synergy. The agreed price splits the synergy.
- Cash offers give the target's holders certainty; share offers make them share the risk that synergy fails.
- Typical deal steps: screen targets, value them (DCF, comparable companies, precedent deals), negotiate, carry out due diligence, obtain approvals, integrate.
- Companies Act 2013, ss.230-232: a scheme of merger needs approval by shareholders and creditors and sanction by the NCLT.
- SEBI (SAST) Regulations 2011: acquiring 25% or more of the voting rights in a listed company triggers an open offer for at least 26% of the total shares.
- The Competition Commission of India must approve combinations above set asset or turnover thresholds.
NET asks you to classify a merger (horizontal, vertical, conglomerate, reverse), match takeover defences with their meaning, and solve synergy, exchange-ratio and EPS numericals.
Typical MCQ: “A tyre maker buys a rubber plantation. Which type of merger is this?” Vertical (backward) integration: it moves to an earlier stage of its own supply chain. Trap: it is not conglomerate, because the businesses are linked.
Typical MCQ: “Is a bear hug a takeover defence?” No. It is an attack: an offer so attractive that the target's board cannot easily refuse it.
Defence zoo: the Pac-Man bites back, the white knight rescues, the crown jewel is sold, the poison pill dilutes and the golden parachute pays the managers.
