Before you model a transaction you classify it, because four independent choices determine the accounting, the tax, the risk, and even who the natural buyer is. Miss the classification and you will build the wrong model.
Axis 1. Strategic vs financial buyer. A strategic (or "trade") buyer is another operating company buying for synergies and strategic fit: it can pay more because it expects to fold the target into an existing platform, cut duplicate costs, or cross-sell. A financial buyer (private equity, a buyout fund) buys to own for a while and sell, funding the purchase with heavy debt (the LBO of M3.09) and earning its return from deleveraging, operational improvement, and multiple expansion, not synergies. The distinction predicts behavior: strategics justify higher prices with synergy stories (and often overpay); financial buyers are disciplined by the arithmetic of leverage and a target internal rate of return, and walk when the price stops working. When both bid for the same asset, the strategic usually wins the auction and the financial buyer usually keeps its money, which tells you something about who is more likely to be overpaying.

How do cash vs stock and share vs asset deals differ?
Axis 2. The consideration: cash, stock, or mixed. How the buyer pays reshapes the whole analysis. Cash (funded from balance-sheet cash or new debt) gives target shareholders certainty and a clean exit. It also hands them a taxable event, and it concentrates all the deal risk and all the upside on the acquirer's existing owners. Stock hands target shareholders paper in the combined company. They share in the synergies and the risk, the acquirer conserves cash and debt capacity, and (in a properly structured deal) the exchange can be tax-deferred. Mixed consideration blends the two. The choice signals confidence: an acquirer paying stock is, in part, telling you its shares are not cheap (why spend dear currency otherwise?), while an all-cash bid at a fat premium is a louder vote of conviction, a nuance you will meet again in the accretion math and among the common mistakes.
Axis 3. Stock (share) purchase vs asset purchase. In a share purchase the buyer acquires the target's equity and inherits everything: assets, liabilities, contracts, and contingent risks (litigation, tax, environmental). In an asset purchase the buyer cherry-picks specific assets and assumes only named liabilities, and gets a stepped-up tax basis in the assets it buys (depreciable again, and valuable). Sellers usually prefer share deals (clean exit, often better tax); buyers often prefer asset deals (risk-shedding, tax step-up). So the structure is negotiated, and the tax gap is frequently split in the price. For public-company mergers the structure is usually a statutory merger (one entity legally absorbs the other by operation of law and a shareholder vote), not an asset sale.
Friendly vs hostile takeovers
Axis 4. Friendly vs hostile, and the route to control. A friendly deal is negotiated with the target board, which then recommends it to shareholders. A hostile approach goes around a resisting board, via a tender offer made directly to shareholders, or a proxy fight to replace the directors. Defenses exist (the poison pill/shareholder-rights plan, staggered boards, white knights). In India, the route to a listed target additionally runs through the SEBI Takeover Regulations (SAST), 2011: crossing 25% of voting rights triggers a mandatory open offer to buy at least 26% more from public shareholders at a regulated minimum price, and a creeping-acquisition limit caps how fast an existing large holder can add. Hostile deals are rare in India precisely because promoter blocks usually make them impossible. Control is typically negotiated, not seized.
Equity value vs enterprise value in a deal
The vocabulary you must hold precisely. Equity value (or equity purchase price / offer value) is what you pay the shareholders. Enterprise value is equity value plus net debt assumed: what you pay for the business, independent of how it was financed. The control premium is the excess of the offer price over the target's unaffected share price (the price before the deal leaked or was announced), empirically often 20–40% for public targets. Confusing equity value with enterprise value, or the affected with the unaffected price, is the most common rookie error in the room; the sources and uses section forces you to keep them straight.
