How to Evaluate a Startup Acquisition LOI: A Founder's Guide

Receiving a Letter of Intent (LOI) to acquire your startup feels like a victory. But it’s not the finish line. It’s the starting gun for a high-stakes, asymmetric battle where your leverage is highest in one fleeting moment: right before you sign.

An LOI is mostly non-binding, but it frames the entire negotiation. More importantly, it contains a trap that obliterates your negotiating power: the binding exclusivity or “no-shop” clause. The moment you sign, you are legally prohibited from speaking to other potential buyers for 30-90 days. Your ability to create a competitive dynamic vanishes.

This guide will give you the framework a seasoned operator uses to analyze an LOI. We’ll dissect the terms, find the hidden traps, and show you how to negotiate the points that actually determine your outcome.

The Anatomy of an LOI: Four Key Battlegrounds

To analyze an LOI, you must see it as four distinct battlegrounds. Each requires scrutiny from you, your co-founders, your M&A lawyer, and your tax advisor. Get these right, and you protect your outcome. Get them wrong, and the headline price becomes a fantasy.

The Purchase Price: The real math behind the headline number. · The Deal Structure: The tax consequences of how you sell. · Your Future: The terms defining your new job and restrictions. · The Process Rules: The binding clauses that govern the deal.

Battleground 1: Deconstructing the "Real" Purchase Price

The number on the first page is designed to create emotional attachment. Your actual proceeds are always lower. A $20M offer can easily be worth less than an $18M offer. The difference is in the details.

Cash vs. Stock

Certainty is king. An all-cash deal means you know exactly what you get at closing. Stock introduces significant risk and requires you to diligence the buyer as thoroughly as they are diligencing you.

Public Company Stock: This is the most straightforward stock offer, but it’s not cash. You’ll likely face a lock-up period of 6-12 months where you cannot sell. The stock price can drop dramatically in that time. Model a 20-30% haircut to the value to be conservative. · Private Company Stock: This is the riskiest proposition. You are trading your illiquid startup stock for someone else’s. You must demand information on their business: What is the current 409A valuation? What is the full capitalization table? What is the liquidation preference stack above you? When is the next funding round? A path to liquidity is years away, if it comes at all.

The Earn-Out: High-Risk, Low-Reward

An earn-out is a portion of the price you only receive if the business hits performance targets after the acquisition. Buyers frame it as a way to "share in the upside." You should see it for what it is: a lottery ticket you will likely not cash.

Common Mistake: Believing you can control the outcome. Once you sell, you don't control the budget, strategy, or headcount. The buyer can, deliberately or through incompetence, make the targets impossible to hit. Treat any earn-out as having a 75% chance of paying out $0.

If you can't get the earn-out removed, negotiate to make the targets ironclad and tied to metrics you directly influence. A typical earn-out is 15-30% of the deal value over 12-24 months.

Bad Target: "$5M in new product revenue." The buyer can under-resource the product. · Better Target: "Retain 95% of the top 10 customer logos (as listed in Appendix A) for 12 months post-close." This is harder for the buyer to sabotage.

The Indemnity Escrow: Your Money on the Sideline

A buyer will hold back a portion of the price in escrow to cover any breaches of your reps and warranties (e.g., an IP infringement claim emerges post-closing). This is standard, but the terms are negotiable.

Market Terms: Expect 10-15% of the purchase price held for 12-18 months. On a $20M deal, that’s $2M-$3M of your money held hostage. · How to Negotiate: · Percentage and Duration: Argue for a lower percentage (5-10%) and a shorter duration (12 months). · The Basket: Demand a "deductible" basket. This means the buyer can only make a claim after the total value of claims exceeds a certain threshold (e.g., 1% of the purchase price), and they can only recover the amount over that deductible. This prevents them from nickeling-and-diming you for minor issues.

The Working Capital Adjustment: The Deal-Killing Trap

This is the most common and painful trap for founders. The LOI will state the price assumes a "normal" or "target" amount of working capital at closing. Working capital is, roughly, Current Assets - Current Liabilities .

The Trap: The buyer defines this target vaguely in the LOI. During diligence, they find the month where your working capital was highest and define that as the target. At closing, your actual working capital is lower, and they deduct the shortfall dollar-for-dollar from your proceeds. A $10M deal can become an $8.5M deal overnight.

The Fix: NEVER accept a vague working capital target. Insist on a specific, fixed dollar amount (e.g., "$500,000") or a clear formula in the LOI itself ("The working capital target will be the average of the trailing six month-end working capital balances"). This defangs the weapon.

Battleground 2: Deal Structure (Stock Sale vs. Asset Sale)

This decision has massive tax implications. Your M&A lawyer and tax advisor are non-negotiable here. For most VC-backed startups, there is only one acceptable answer.

Stock Sale

How it works: The buyer purchases the shares of your company from all shareholders. The corporate entity, with all its assets and liabilities, transfers to the buyer.

Why you want it: This is the standard for VC-backed companies. For most founders and investors, gains qualify for Qualified Small Business Stock (QSBS), resulting in enormous tax savings (potentially 0% federal tax). The liabilities transfer to the buyer.

Asset Sale

How it works: The buyer purchases specific assets (code, brand, contracts) but leaves the corporate shell and its liabilities with you. The cash sits in your company, and you must liquidate the corporation to distribute it.

Why the buyer wants it: They avoid inheriting unknown liabilities and get a tax benefit called a "step-up in basis," allowing them to depreciate the assets they just bought. · Why it's a disaster for you: It can trigger double taxation. First, the corporation pays tax on the sale of the assets. Then, you pay capital gains tax when the proceeds are distributed to you as a shareholder. It also disqualifies gains from QSBS treatment.

Your Stance: Insist on a stock sale. If the buyer is adamant about an asset sale, the price must be significantly higher (a "gross-up") to compensate for your adverse tax hit. Make them pay for their preference.

Battleground 3: Your Future and Your Freedom

The deal isn't just about money; it defines your life for the next few years. Don’t leave these terms to be "figured out later." Your leverage here is maximal before you sign the LOI.

Founder Employment & Compensation

You’re going from CEO to a middle manager. Understand what that means. The LOI should specify your new reality.

Role and Reporting: What is your exact title? What are your KPIs? Who do you report to? Ask to speak with your future manager before signing the LOI. · Compensation: What is your salary, target bonus, and severance policy? · Founder Equity: You will likely get a new grant of RSUs or options in the acquirer. Is it on a standard 4-year vesting schedule with a 1-year cliff? You just sold your company; ask for accelerated vesting (e.g., monthly), removal of the cliff, or a larger initial grant to reward the value you just delivered.

The Non-Compete Agreement

No buyer will acquire you without a non-compete. But you must limit its scope to be reasonable.

Duration: 2-3 years is standard. 5 years is too long. · Scope: The definition of a "competing business" should be narrowly tailored to your startup's specific market, not the acquirer's entire universe of activities. · Geography: Restrict it to the countries where you currently operate. · Carve-outs: Explicitly carve out your right to be an angel investor, advisor to non-competing companies, public speaker, or to start a business in an unrelated field. Ensure the non-compete is void if you are terminated without cause.

Battleground 4: The Process Rules (The Binding Part)

Pay extra attention here. While the price is just an expression of intent, these clauses are legally enforceable contracts the moment you sign.

The "No-Shop" / Exclusivity Clause

This is the most critical binding clause. For 30-90 days, you are forbidden from talking to any other potential acquirer. This is the price you pay for the buyer to commit resources to expensive diligence.

Your Tactic: Keep the no-shop as short as you possibly can. A shorter period maintains urgency on the buyer. 30 days is a great outcome. 45 days is acceptable. Anything over 60 days is a red flag that signals a disorganized buyer or one who wants to "ice" you while they look at other options.

Confidentiality and Closing Conditions

The LOI will include a binding confidentiality agreement for the negotiations, which is standard and mutual. It will also list "closing conditions"—things that must be true for the deal to close. Review these to ensure they are standard and don’t contain hidden "gotchas," like requiring a certain percentage of non-critical employees to accept offers.

Red Flag Checklist: When to Walk Away

Vague Purchase Price Terms: Loose definitions around working capital, earn-outs, or stock consideration are invitations for the buyer to re-trade the price later. · Excessively Long No-Shop: A 90+ day request signals they are uncommitted, disorganized, or planning to use the time to grind you down on price. · Unclear Financing: The buyer is evasive about how they will fund the deal. For any buyer that isn’t a massive public company, you can ask for a "Sources and Uses" slide or proof of funds. · Refusal to Let You Meet Your Future Boss: A major red flag about the acquirer's culture and the reality of the role you’re stepping into. · Aggressive Stance on Asset Sale: A rigid insistence on an asset sale without a significant price gross-up suggests they are trying to pass major tax burdens on to you. · "Too Good to Be True" Valuation: A price wildly above market can be a tactic to get you to sign a long no-shop, after which the buyer will use diligence "findings" to lower the price to a market rate.

How to Apply This This Week: Your LOI Action Plan

Hire Your Team Immediately. Call an M&A lawyer, not your standard corporate counsel. This is a specialized, high-stakes sport. Call your tax advisor. You cannot evaluate the offer without them. · Build the "Net Proceeds" Waterfall. Create a spreadsheet that models the real outcome. Start with the headline price, then subtract legal/banker fees, the full escrow amount, and potential taxes. Heavily discount the earn-out (e.g., assume a 20% payout). This is the number you should anchor on. · Identify Your 3-4 "Must-Win" Points. Before redlining the document, create a simple list of your key issues with your lawyer. This could be the no-shop period, the working capital peg, and the removal of a founder cliff. · Send the "Enthusiastic but Firm" Reply. Control the narrative. Your first response to the buyer should be a phone call or short email expressing gratitude and excitement, while also framing the next step.

"Thanks so much for the offer. We’re very excited about the potential of partnering with you. Our team is reviewing the LOI with counsel now and we’ll be back to you in a couple of days to align on a few key points before we move to a full redline. We're looking forward to getting this done."

A well-negotiated LOI doesn’t just secure a better price; it de-risks the entire closing process and sets the foundation for a successful integration. This is your last moment of true leverage. Use it wisely.
