In 2025, earnout prevalence in middle-market deals dropped to 18%, down from 26% in 2023, according to the ABA's 2025 Private Target M&A Deal Points Study. Buyers and sellers are aligning on price faster and locking terms earlier, which puts more weight on the preliminary document that captures those terms. The term sheet vs loi decision is where that alignment happens, and founders who treat the two as interchangeable often discover, months later, that they gave up negotiating power they didn't know they had.
The short answer: a term sheet outlines headline economics in bullet points, non-binding by design. A letter of intent formalizes those terms in a longer document with specific binding provisions, usually exclusivity, confidentiality, and expense allocation. In institutional processes, you use both in sequence. In direct owner-operator deals, you typically go straight to an LOI.
What a Term Sheet Actually Is
A term sheet is a concise, bullet-point document that outlines the headline economics of a proposed deal: purchase price, deal structure, key protections, and any conditions the buyer wants to flag before either party spends heavily on due diligence or legal work. It typically runs 1-5 pages, is explicitly non-binding, and is designed to be marked up quickly during negotiation.
As M&A advisory firm Embarca describes it, the term sheet "is a concise, non-binding outline that aligns the buyside and sellers on headline valuation, structure, and key protections before anyone spends heavily on diligence or legal work." The point isn't to lock parties in. It's to test alignment cheaply.
In competitive auctions and PE-backed processes, the typical sequence runs: Indication of Interest (IOI), then Term Sheet, then LOI with binding exclusivity, then Purchase Agreement. Each step narrows the field. The IOI signals interest with a rough valuation range. The term sheet nails down the number and the structure. Only then does the deal move into an LOI, where exclusivity gets negotiated and the seller takes the business off-market.
A term sheet's power is what it doesn't do. It doesn't grant exclusivity. It doesn't obligate confidentiality (that lives in a separate NDA). It doesn't commit either party to anything except a shared understanding of what a full offer would look like. That makes it useful for stress-testing a buyer's seriousness without giving up optionality. At Iconic, we often push for a term sheet step in institutional processes for exactly that reason: to force clarity on the headline numbers before either side burns weeks of legal spend on an LOI that might not survive first contact with diligence.
Term sheets are less common in direct owner-operator sales, where a single buyer approaches a single seller and the negotiation moves in one motion. In that path, the buyer typically skips the term sheet and drafts a letter of intent directly.
What a Letter of Intent Actually Is
A letter of intent is a longer, narrative document, typically 3-8 pages written in business-letter format, that describes the proposed transaction in enough detail to serve as the blueprint for the definitive agreement. It covers purchase price, deal structure (asset sale vs stock sale), payment terms, escrow and holdback amounts, representations and warranties, closing conditions, and the timeline to closing.
Where the term sheet is a menu, the LOI is the recipe. Every material aspect of the deal appears in the LOI in enough specificity that both sides know what they're signing up for, even though most of the language is non-binding.
That last point is the one founders repeatedly miss. As Embarca Advisors puts it: "While most of an LOI remains non-binding, three provisions almost always turn into enforceable commitments: Exclusivity, which gives the buyer a 45 to 120-day window where you're not allowed to shop the deal; Confidentiality, which keeps financials, customer, employee and any other sensitive data out of the public view and away from competitors; Expense or Break-up Fees."
Everything else, including price, structure, earnout, and escrow, is non-binding. Which means that after the LOI is signed, if the buyer's diligence surfaces something unexpected, the buyer can come back and ask to renegotiate. That's where "retrading" happens, and it's why the due diligence preparation checklist matters as much as anything you do before signing.
Exclusivity is where the seller has the most to lose. During the exclusivity window, typically 30-90 days, though Goodwin Law data shows 40% of LOIs now run 61+ days, the seller cannot solicit or accept competing offers. If the deal falls apart at day 80, the seller has spent nearly three months off the market with little to show for it. Most M&A advisors recommend exclusivity not exceed 60 days for deals under $5M, with 30-45 days preferred by sellers who want to keep their negotiating position intact. If you're drafting your own document, Iconic's LOI template shows what a seller-friendly exclusivity clause looks like in practice, including the early-termination triggers most standard forms omit.
Term Sheet vs LOI: A Side-by-Side Comparison
| Dimension | Term Sheet | Letter of Intent |
|---|---|---|
| Format | Bullet-point, 1-5 pages | Narrative business letter, 3-8 pages |
| Binding provisions | Almost none; non-binding by design | Exclusivity, confidentiality, expense/break-up fees, governing law |
| Typical use case | PE and institutional processes; competitive auctions | Direct owner-operator sales; final step before due diligence |
| Level of detail | Headline economics only (price, structure, key protections) | Full deal blueprint including reps, warranties, closing conditions, timeline |
| Exclusivity granted | No | 30-120 days typical; 45-90 most common |
| Position in sequence | Before LOI in institutional deals; skipped in direct deals | Before purchase agreement in every deal |
| Signal to counterparty | Alignment on headline terms | Serious intent to close; buyer prepared to spend on diligence |
| Renegotiation risk | Low (nothing binding to enforce) | Moderate to high (price and structure non-binding, subject to diligence) |

The term sheet vs loi comparison above captures the mechanical differences. The strategic difference is subtler: a term sheet is a filter, and an LOI is a commitment. When a buyer signs a term sheet, they're saying "if diligence checks out, this is roughly the deal." When they sign an LOI, they're saying "we're prepared to spend six figures on legal and diligence in exchange for exclusivity, and if it works, this is the deal." Those are different levels of skin in the game.
For sellers, that difference matters most in one specific situation: when a buyer presents an LOI that reads more like a term sheet. Vague price ranges, undefined structures, and wide "subject to" language are red flags. An LOI that isn't specific enough to be enforceable on its binding provisions, but broad enough that the buyer can retrade in any direction post-signing, is worse than a well-drafted term sheet followed by a proper LOI. That's the pattern that leaves sellers 90 days off the market with no closed deal to show for it.
Which Document Fits Your Deal? A Decision Framework
Which document you use depends less on preference than on the shape of the transaction. Three factors drive the call.
Buyer type. The lower middle market buyer mix has shifted meaningfully: PE and independent sponsors declined from 61% of closed LMM deals in 2021 to 45% in 2025 per Axial's analysis, while individual investors (13%) and search funds (14%) grew. PE and independent sponsor buyers almost always run a term-sheet-then-LOI sequence; they want to test alignment before committing legal spend. Individual buyers and search funds more often go straight to an LOI, both because they're negotiating one deal at a time and because their advisors typically favor a single, more detailed document.
Deal complexity. Deals with rollover equity, earnouts, seller notes, or complex closing conditions benefit from a term sheet step. The headline structure is worth stress-testing before either side commits to exclusivity. Straightforward all-cash asset purchases can typically skip the term sheet without losing anything.
Competitive dynamics. If you're running a competitive process with multiple bidders, a term sheet lets you compare offers on comparable terms without granting exclusivity to any single buyer prematurely. If you're negotiating with a single buyer identified through a relationship or targeted outreach, the term sheet adds a step without meaningful benefit; the LOI is where the real negotiation happens.
There is a fourth consideration worth naming: what the differences between letters of intent and term sheets look like in practice depends heavily on who drafts them. Buyer-drafted versions typically feature exclusivity at the long end (75-120 days), narrow seller termination rights, and diligence scopes broad enough to justify retrading on almost any finding. Whether you're weighing a business broker vs m&a advisor for the process, or working with counsel directly, insist on marking up the first draft rather than signing as-is.
Between LOI signing and purchase agreement execution, typically 60-120 days for middle-market deals, the deal moves through due diligence and full contract negotiation. This is also the window where roughly one-third of signed LOIs die. In Axial's 2026 LMM outlook survey, valuation expectations drove 28.3% of deal failures, narrowly ahead of diligence findings at 24.5%. The term sheet vs loi choice you make early (and how carefully those intent and term sheets get drafted) sets the frame for that renegotiation window; the tighter the LOI, the less room the buyer has to retrade.
Frequently Asked Questions
Is an LOI binding or non-binding?
An LOI is a hybrid document. Most of it, including price, deal structure, payment terms, and closing conditions, is explicitly non-binding and subject to renegotiation based on due diligence. However, three provisions are almost always legally binding: exclusivity, confidentiality, and expense/break-up fee allocation. Governing law and dispute resolution clauses are also typically enforceable, which is why the exact language of those provisions matters more than most sellers realize.
How long is an LOI exclusivity period typically?
Exclusivity periods typically run 30-90 days, with 45-90 days most common in middle-market deals. Goodwin Law data indicates 40% of LOIs now include windows of 61+ days, reflecting PE buyers' push for longer diligence periods. For Main Street deals under $5M, most advisors recommend exclusivity not exceed 60 days, with 30-45 days preferred by sellers. Whatever the length, negotiate early-termination rights tied to specific buyer milestones so the clock doesn't run out on a stalled deal.
What provisions in an LOI are actually legally binding?
Typically four: exclusivity (also called "no-shop"), confidentiality, expense or break-up fee allocation, and choice of governing law. Everything else, including price, deal structure, escrow, representations, and closing conditions, is non-binding language that both parties are free to renegotiate before the definitive purchase agreement is signed. This is why some sellers push for "no retrading" language and materiality thresholds in the LOI's non-binding sections, to limit the buyer's practical ability to renegotiate post-signing.
Can the purchase price change between LOI signing and purchase agreement?
Yes. Because the price stated in an LOI is a non-binding term, buyers can and do renegotiate ("retrade") based on due diligence findings. Common triggers include EBITDA discrepancies, undisclosed liabilities, customer concentration issues, or working capital shortfalls. Well-drafted LOIs limit retrading by defining materiality thresholds, requiring "affirmative response" from buyers on diligence items, and including "no retrading" language that constrains what can trigger a price adjustment.
How long does it take to go from LOI to closed deal?
For middle-market deals, expect 60-120 days from LOI signing to purchase agreement execution, plus another 30 days on average from PA signing to closing. Smaller deals ($1M to $5M) may close faster (90-120 days total from LOI); larger or more complex deals can stretch to 6-12 months. In the ABA's 2025 study of 139 middle-market deals, 30% signed and closed the purchase agreement simultaneously, while 70% had a gap between PA execution and closing.
Where to Start
The term sheet vs loi distinction isn't academic. It determines how much room you have to negotiate during the most consequential transaction of your ownership. A well-drafted LOI with tight exclusivity, defined materiality thresholds, and no-retrading language protects the deal you thought you were signing. A loose LOI, or one that reads like a term sheet dressed up in legalese, gives the buyer room to renegotiate at your expense during the 60-120 days when your business is off the market.
Before you sign anything, understand which provisions are binding, what your exclusivity window looks like, and what happens if the buyer misses a diligence milestone. If you're preparing to receive an LOI or evaluating one already on the table, a complimentary valuation from Iconic is a useful starting point to make sure the number in the document reflects what the market would actually pay. Iconic's M&A process typically closes 50% faster than traditional M&A timelines, based on internal data compared against IBBA Market Pulse and BizBuySell industry averages, largely because we push tighter LOI language and shorter exclusivity windows on the front end, before the clock starts.
