Share purchase agreement (SPA)

The definitive contract for the sale of all (or a controlling portion of) a corporation's shares.

Definition
A Share Purchase Agreement (SPA) is the definitive contract governing the sale of all or a controlling portion of a corporation's shares from selling shareholders to a buyer. It specifies the purchase price and payment mechanics, the representations and warranties made by the parties, the covenants binding pre-close and post-close, the conditions to closing, and the indemnification framework. The SPA is the primary M&A document in share-deal exits, distinct from an Asset Purchase Agreement (APA) used in asset-deal exits.

Key SPA sections

A typical SPA has 8-10 substantive sections that allocate risk between buyer and seller:

  • Purchase price and payment mechanics: closing cash, escrow, earn-out, working capital adjustment, equity rollover
  • Representations and warranties: factual statements about the target — title to shares, corporate organization, financial statements, contracts, litigation, intellectual property, taxes, employees, environmental
  • Covenants: conduct of business between signing and closing, pre-closing access, post-closing non-competes, employee retention
  • Conditions to closing: regulatory approvals, third-party consents, no material adverse change, accuracy of reps
  • Indemnification: caps, baskets, survival periods, escrow mechanics for breaches of reps and covenants
  • Termination rights: outside date, no-shop, fiduciary out for public-company targets

Share deal vs asset deal

The SPA is the share-deal counterpart to the Asset Purchase Agreement (APA). Key differences:

  • Share deal (SPA): buyer acquires the corporation itself, with all its assets and liabilities. Simpler from an operational continuity standpoint; preserves contracts, employees, and licences without re-assignment.
  • Asset deal (APA): buyer acquires specific assets and assumes specific liabilities. More flexibility to leave behind unwanted assets or liabilities; requires consents for assigning contracts and re-issuing licences.
  • Canadian tax considerations often favor share deals for sellers (LCGE eligibility, lower effective tax rate) and asset deals for buyers (step-up in tax basis of acquired assets).

Negotiation dynamics in Canadian M&A

Canadian SPA negotiations are heavily influenced by US precedents (NVCA model documents, ABA model SPA) but adapted to Canadian law. Key Canadian-specific points: bilingual issues for Quebec targets (English-only SPAs sometimes require Quebec-law sub-agreements); environmental indemnities for industrial targets; tax warranties covering CRA reassessment risk; and competition law conditions for transactions above HSR-equivalent thresholds (Investment Canada Act, Competition Act).
