When a buyer acquires a company through a merger (rather than an asset or stock purchase), the specific merger structure has significant consequences for contract continuity, liability exposure, and regulatory compliance. The reverse triangular merger has become the dominant structure in US acquisitions for good reasons - but understanding why requires understanding what the alternatives actually do and when each makes sense.

The Three Merger Structures: How Each Works
Forward Merger (Direct Merger)
Structure
Target merges directly into Acquirer. Target ceases to exist. Acquirer absorbs all assets AND all liabilities of the Target.
Consequence
All Target contracts must be assigned to Acquirer (triggering assignment clauses). All licenses re-issued. Acquirer inherits Target's full liability history. Simple structure, maximum risk.
Reverse Triangular Merger (Most Common)
Structure
Acquirer creates NewCo (Merger Sub). NewCo merges INTO Target. Target survives as wholly-owned subsidiary of Acquirer. NewCo disappears.
Consequence
Target's contracts remain with Target entity - no assignment needed. Target's licenses and permits survive. Liabilities stay in the subsidiary, isolated from Acquirer. This is why it dominates.
Forward Triangular Merger
Structure
Acquirer creates NewCo (Merger Sub). Target merges INTO NewCo. NewCo survives (not Target). Target entity ceases to exist but assets/liabilities sit in NewCo subsidiary.
Consequence
Target contracts must be assigned to NewCo (Target no longer exists). Can qualify as a tax-free reorganization under 368(a)(2)(D). Less common - used for specific tax planning purposes.

Why Contract Continuity Drives the Reverse Triangular Preference
The practical reason reverse triangular mergers dominate is straightforward: in a forward merger, the target entity ceases to exist. Every contract to which the target was a party - customer agreements, supplier contracts, leases, software licenses, government permits - must be assigned to the acquirer. Most commercial contracts include anti-assignment clauses requiring the counterparty's consent before assignment. Gathering consents from dozens or hundreds of counterparties is time-consuming, expensive, and sometimes impossible if a counterparty refuses.
In a reverse triangular merger, the target entity survives. Its contracts remain with it. No assignment is required. The counterparties' only exposure is to a change-of-control provision (if any) in the specific contract, which is a narrower and more manageable issue. For businesses with complex contractual ecosystems - SaaS companies with enterprise agreements, healthcare businesses with government contracts, franchises with franchise agreements - the reverse triangular merger is often not a preference but a necessity.

Frequently Asked Questions
What is the difference between a forward merger and a reverse triangular merger?
In a forward merger, the target company merges directly into the acquirer - the target ceases to exist and all of its assets and liabilities are absorbed by the acquirer. The acquirer continues as the surviving entity. In a reverse triangular merger, the acquirer creates a new subsidiary that merges into the target - the target survives as a wholly-owned subsidiary of the acquirer. The merger subsidiary disappears, but the target entity lives on. Reverse triangular mergers are far more common because the target's survival preserves existing contracts, licenses, and permits without requiring third-party consents.
Why is the reverse triangular merger the preferred structure for most acquisitions?
The reverse triangular merger is preferred because it preserves the target as a surviving legal entity. This means: existing contracts remain in place without assignment (they stay with the surviving entity); government licenses and permits do not need to be re-issued to a new entity; regulatory approvals (healthcare, financial services, government contracting) can survive the merger if change-of-control provisions are handled correctly; and customers and vendors experience no disruption. A forward merger, by contrast, transfers all contracts and obligations of the target to the acquirer - triggering assignment clauses and change-of-control notifications in virtually every material agreement.
What is a forward triangular merger?
In a forward triangular merger, the acquirer creates a new subsidiary, and the target merges into that subsidiary - the subsidiary survives (not the target). This is distinguished from a reverse triangular merger in that the target entity does not survive. Forward triangular mergers are sometimes used for tax reasons (they can qualify as a reorganization under IRC Section 368(a)(2)(D)) or when the acquirer wants to isolate the target's liabilities in a subsidiary without keeping the target's legal entity. They are less common than reverse triangular mergers because of the contract assignment issue.
Does a reverse triangular merger require target shareholder approval?
Yes, in most jurisdictions. Target shareholders must approve the merger plan. The standard for approval varies by state - in Delaware, a majority of shares entitled to vote is typically required, though the certificate of incorporation may require a higher threshold. Acquirer shareholder approval is generally not required in a reverse triangular merger because the acquirer's subsidiary is doing the merging (not the acquirer itself), and the acquirer issues consideration directly to target shareholders without needing its own shareholder vote (unless the consideration is stock that exceeds the NYSE/Nasdaq threshold triggering a shareholder vote requirement).
What is the relationship between a reverse merger and a reverse triangular merger?
These are different concepts that are frequently confused. A 'reverse merger' (or 'reverse takeover') refers to a private company going public by merging into an existing public shell company - this is a method of accessing public markets without a traditional IPO. A 'reverse triangular merger' is a specific deal structure where the acquirer's subsidiary merges into the target, leaving the target as a surviving subsidiary. The 'reverse' in reverse triangular merger refers to the direction of the merger (the subsidiary goes into the target, rather than the target going into the acquirer). They are unrelated structures that share the word 'reverse'.
