A term sheet is a document that summarises the principal commercial and legal terms proposed for a transaction before the parties execute definitive agreements. It is common in venture capital, private equity, corporate finance, mergers and acquisitions, lending and other investment transactions. A term sheet allows the parties to identify the major points of agreement and disagreement before incurring the time and cost associated with detailed legal drafting.
In a financing transaction, it may describe the proposed investment amount, valuation, security type, ownership, share class, governance rights, investor protections and conditions to completion. A term sheet is normally less detailed than the final contracts and does not necessarily contain every legal provision needed to complete the transaction. Its legal effect depends on its wording and the applicable law. Some provisions can be expressly non-binding while others, such as confidentiality, exclusivity or governing-law provisions, can be intended to create binding obligations.
In a venture financing, a term sheet can specify whether the investor will purchase ordinary shares, preferred shares, convertible securities or another instrument. It can state the proposed investment amount, pre-money or post-money valuation, resulting ownership, liquidation preference, dividend rights, conversion rights and voting arrangements. Governance terms can include board composition, observer rights, information rights and investor consent over specified corporate actions.
Other provisions can cover founder vesting, employee option pools, anti-dilution protection, pre-emption rights and participation rights in later financing rounds. Each term can affect the transaction's economics or control structure. Two investment offers with identical headline valuations can produce materially different outcomes if their liquidation preferences, option-pool treatment, governance rights or anti-dilution provisions differ. A term sheet therefore needs to be assessed as an integrated package rather than reduced to the proposed valuation.
The binding status of a term sheet is a common source of misunderstanding. A document can state that most commercial terms are subject to definitive documentation while expressly making certain provisions legally binding. Confidentiality can require the parties to keep negotiations private, while an exclusivity or no-shop provision can prevent the company from negotiating with competing investors for a specified period. A governing-law or costs provision can similarly have legal significance.
Whether a provision is enforceable depends on the document's language, the parties' conduct, the circumstances and applicable law. The statement that term sheets are “never binding” is therefore inaccurate. Parties should clearly identify which provisions are intended to have immediate legal effect and which merely record a proposed commercial understanding subject to further agreement.
In mergers and acquisitions, documents serving a similar preliminary function may be called letters of intent, heads of terms or memoranda of understanding. The terminology varies by jurisdiction and transaction type, and these documents are not necessarily legally interchangeable. A transaction summary might describe the proposed purchase price, assets or shares to be acquired, financing arrangements, due-diligence process, conditions to completion, timetable and exclusivity.
In UK commercial practice, “heads of terms” is a common expression, while “term sheet” is especially familiar in investment and financing. The underlying purpose is to establish the principal terms before detailed definitive agreements are prepared. The title itself does not determine legal effect. The wording and surrounding circumstances remain decisive.
Term sheets make negotiations more efficient because they force the parties to resolve major commercial issues early. If an investor requires a particular valuation, board seat, liquidation preference and option-pool arrangement, these matters can be negotiated before lawyers draft extensive documentation. This can prevent substantial legal expenditure on a transaction that fails because the parties fundamentally disagree about economics or control. The term sheet also provides a drafting reference for the definitive agreements.
However, a term sheet can omit details that later prove important. The size and timing of an employee option pool, treatment of convertible securities, definitions of fully diluted ownership and rights attached to preferred shares can materially change the final economics. A term sheet should therefore be treated as a framework for the transaction rather than a complete substitute for the final contracts.
Valuation terminology is especially important. Pre-money valuation generally refers to the agreed value of the company immediately before the new investment, while post-money valuation includes the new capital. In a simplified transaction involving a £9 million pre-money valuation and £1 million investment, the post-money valuation would be £10 million and the new investor would hold approximately 10% immediately after completion, subject to the capitalisation assumptions.
The term sheet may also specify whether an option pool is created or enlarged before or after the financing. That distinction can shift the economic burden of the pool between existing shareholders and the new investor. Liquidation preferences can also affect proceeds on an exit independently of headline ownership percentages. Consequently, founders and investors should understand the numerical and legal implications of each major provision rather than focusing only on the proposed company valuation.
The advantages of a term sheet include clarity, negotiation efficiency, identification of major transaction issues and a structured foundation for legal drafting. Its limitations include incompleteness, possible ambiguity and the risk that parties assume a point has been finally agreed when it remains subject to definitive documentation.
A transaction can still fail after a term sheet because due diligence reveals liabilities, intellectual-property problems, financial weaknesses or other concerns, because financing conditions are not satisfied or because the parties cannot agree final legal language. A signed term sheet therefore does not necessarily mean that completion is guaranteed. It usually represents an important stage in negotiations rather than the final transfer of money or ownership.
The expression “term sheet” reflects its function as a document listing the terms of a proposed transaction. Related concepts include heads of terms, letter of intent, memorandum of understanding, investment proposal and transaction summary, although the legal meaning of each can differ. A term sheet should be distinguished from definitive documents such as a share subscription agreement, share purchase agreement, shareholders' agreement, loan agreement or other operative contract. Those definitive agreements establish the legal obligations governing the completed transaction.
The term sheet instead provides a structured record of the principal proposed terms and can guide due diligence, negotiation and drafting. Its importance is particularly high in startup financing because it can determine the economic architecture of a funding round before detailed documentation converts that agreement into enforceable contractual arrangements.
