Merger and Acquisition Contract Sample: Clause-by-Clause APA + SPA Walkthrough (2026)

A working merger and acquisition contract sample for a $25M HVAC asset purchase runs roughly 85 to 110 pages, carries 14 standard clause groups, and is the document that actually closes the deal after the LOI handshake. The SRS Acquiom 2025 Deal Terms Study found that 89% of private-target deals close on either an Asset Purchase Agreement (APA) or a Stock Purchase Agreement (SPA), with reverse triangular mergers covering most of the remainder. This walkthrough opens each clause, explains what the buyer’s counsel is trying to control, and gives sample scaffold language an owner can hand to deal counsel for redlining. Nothing here is legal advice. It is the operating context an owner needs so the lawyer’s draft does not surprise them on the closing call.

What This Actually Means

The definitive agreement is the binding contract that transfers ownership of the business from the seller to the buyer. It comes after the non-binding LOI, after the buyer’s due diligence, and before (or simultaneously with) closing. In an asset deal, the parties sign an APA and the buyer takes specific assets and assumes specific liabilities. In a stock deal, the parties sign an SPA and the buyer takes the entire legal entity, warts and all. In a true merger, the parties sign a merger agreement governed by the relevant state corporate code, most commonly Delaware General Corporation Law Section 259, which provides that the surviving entity inherits all rights and liabilities of the disappearing entity by operation of law.

The contract is doing three jobs at once. First, it transfers the assets or stock. Second, it allocates risk between the parties for anything that goes wrong before, at, or after closing, mostly through representations, warranties, and indemnification. Third, it documents the price mechanics, including any post-closing true-ups for working capital, debt, and cash. The price clause and the indemnification clause are where most of the real money moves after the LOI. According to the SRS Acquiom 2025 study, 73% of private deals include a working capital adjustment, and 71% include an indemnity cap below 15% of the purchase price.

For lower middle market deals, the Capstone Partners 2026 LMM Survey reports that median time from signed LOI to signed definitive agreement runs 75 to 110 days, with the contract itself going through 4 to 7 redline rounds. Owners who understand the clauses going in cut that timeline by roughly 20% and lose less value in the negotiation, because they are not learning the vocabulary on the buyer’s clock.

The 14 Clauses You Need to Understand

1. Parties and Recitals

The opening identifies the legal entities (not the trade names) and recites the deal context. This sounds clerical, but the recitals are referenced when courts interpret ambiguous clauses later. The American Bar Association Mergers and Acquisitions Committee model APA recommends naming the exact LLC or corporation, state of formation, and principal office, then a short recital block describing the business and the transaction.

Sample scaffold: “This Asset Purchase Agreement, dated as of [Closing Date], is entered into by and among Acme HVAC Holdings, LLC, a Delaware limited liability company (Buyer), and Smith Mechanical Services, Inc., a Texas corporation (Seller), and John Smith, an individual residing in Travis County, Texas (Owner). WHEREAS, Seller operates a residential and light commercial HVAC service and installation business in Central Texas; WHEREAS, Buyer desires to purchase substantially all of the assets of the business and assume specified liabilities on the terms set forth herein.”

2. Purchase Price, Payment Mechanics, Escrow, and Holdback

This clause sets the headline number, how it is paid, and what portion sits in escrow as security for the seller’s indemnification obligations. The price is almost always stated as a base amount subject to adjustments (working capital, debt, cash, transaction expenses). Payment can be all cash at closing, cash plus a seller note, cash plus rollover equity, or cash plus an earnout. Escrow is typically 5% to 10% of the purchase price held by a third-party agent for 12 to 24 months. A separate indemnity holdback or representation and warranty insurance policy may stack on top.

Sample scaffold: “The aggregate consideration for the Purchased Assets shall be Twenty-Five Million Dollars ($25,000,000) (the Base Purchase Price), subject to adjustment pursuant to Section 2.4 (Working Capital Adjustment). At Closing, Buyer shall (a) pay to Seller Twenty-Two Million Dollars ($22,000,000) by wire transfer of immediately available funds, (b) deposit One Million Five Hundred Thousand Dollars ($1,500,000) with the Escrow Agent (the Indemnity Escrow), and (c) deposit One Million Five Hundred Thousand Dollars ($1,500,000) with the Escrow Agent (the Adjustment Escrow). The Indemnity Escrow shall be released to Seller eighteen (18) months after Closing, net of any pending or paid claims.”

3. Working Capital Adjustment and True-Up Mechanism

This is the most common source of post-closing disputes. The buyer wants the business delivered with a “normal” level of working capital so it can operate without an emergency cash injection on day one. The parties agree on a target working capital (typically a trailing 12-month average), measure actual working capital at closing, and true up the price up or down for the difference. Per the SRS Acquiom 2025 study, the median post-closing working capital adjustment moves the purchase price by 1.2% in either direction.

The mechanic matters. A poorly drafted working capital clause can hand the buyer a $200,000 to $800,000 windfall on a $25M deal just from definitional ambiguity around accounts receivable aging, inventory reserves, or deferred revenue. Owners should insist on (a) a clear, illustrative example schedule showing how target working capital was calculated, (b) the same accounting methods and consistent application as the historical financials, and (c) a fast dispute mechanism using an agreed accounting firm as expert (not arbitrator).

4. Representations and Warranties

Representations are statements of fact the parties make about themselves and the business. Warranties are the promises that those statements are true. Together they form the spine of the risk allocation. The buyer wants extensive seller reps about the business; the seller wants short, qualified reps about itself. A typical APA contains 30 to 50 seller reps covering organization, authority, financial statements, undisclosed liabilities, taxes, employees, benefit plans, real property, intellectual property, contracts, litigation, compliance with law, environmental, customers and suppliers, insurance, and brokers.

The reps are usually qualified by knowledge (“to Seller’s Knowledge”) and materiality (“except for matters that would not, individually or in the aggregate, have a Material Adverse Effect”). Each qualifier is a real-money negotiation. A knowledge qualifier on the environmental rep can shift $1M to $3M of remediation risk back to the buyer. The Restatement (Second) of Contracts treats reps as actionable statements of present fact, and breaches give rise to a contract claim for damages, which is why the indemnification clause caps and channels those damages.

5. Covenants (Pre-Closing and Post-Closing)

Covenants are promises about future conduct. Pre-closing covenants govern the gap between signing and closing, typically 30 to 120 days. They include operating the business in the ordinary course, no leakage (no special dividends or bonuses), access for buyer’s continued diligence, regulatory cooperation (Hart-Scott-Rodino if applicable), and exclusivity. Post-closing covenants include cooperation on tax filings, transition assistance, treatment of employees, and the restrictive covenants in clause 8.

The ordinary course covenant is where many sellers stumble. Buyers list 15 to 25 specific prohibited actions (no new leases above $X, no compensation increases above Y%, no settlement of litigation above $Z) and any violation gives the buyer a walk right at closing. Owners should review this schedule line by line against their normal monthly operating decisions and push back on anything that would freeze the business.

6. Closing Conditions, Bring-Down, and MAC Clause

Closing conditions are the boxes that must be checked before the buyer is required to fund. They include (a) bring-down of the reps (the reps must still be true at closing), (b) compliance with covenants, (c) no Material Adverse Change (MAC) since signing, (d) regulatory clearances, (e) third-party consents for key customer contracts, leases, and licenses, and (f) delivery of closing documents. If any condition fails, the buyer can walk without paying a break fee in most middle market deals.

The MAC clause is the buyer’s escape hatch. Delaware courts have set a high bar (see Akorn v. Fresenius) requiring a durationally significant decline in earnings power, but the negotiation is still meaningful. Sellers want narrow MAC carveouts for industry-wide events, general economic conditions, changes in law, and pandemics. Buyers want broad MAC application. The SRS Acquiom 2025 study reports 94% of private deals include a MAC closing condition, and 81% carve out general economic and industry events.

7. Indemnification, Survival, Cap, Basket, and De Minimis

This is where the post-closing money actually moves. The seller indemnifies the buyer for breaches of reps and warranties, breaches of covenants, pre-closing taxes, and specifically identified known issues. The structure has four levers:

• Survival period: how long the buyer can bring a claim. SRS Acquiom 2025 median is 18 months for general reps, indefinite for fundamental reps (organization, authority, title, taxes).
• Cap: total dollar exposure. SRS Acquiom 2025 median is 10% of purchase price for general reps, with separate higher caps or no cap for fundamental reps and fraud.
• Basket (deductible or tipping): the threshold the buyer must clear before recovering. SRS Acquiom 2025 median basket is 0.75% of purchase price.
• De minimis: per-claim floor below which a claim does not count toward the basket. SRS Acquiom 2025 median is $25,000 to $50,000 in lower middle market deals.

Representation and warranty insurance (RWI) has changed the math. On deals above $30M, RWI is now used in roughly 65% of transactions per Capstone Partners 2026 data, with retentions of 0.75% to 1% of enterprise value and policy limits of 10% to 20%. RWI lets the seller walk away with a clean break and the buyer collect from the insurer for covered breaches.

8. Restrictive Covenants (Non-Compete, Non-Solicit, Non-Disparagement)

The buyer is paying for the goodwill of the business and does not want the seller to recreate it across the street. Typical terms in a $25M deal: 3 to 5 year non-compete within a defined geography (county, state, or service-area radius), 3 to 5 year non-solicit of customers and employees, and perpetual mutual non-disparagement. Enforceability varies by state. California voids most post-employment non-competes but allows sale-of-business non-competes under Business and Professions Code Section 16601. Texas, New York, Florida, and most other states enforce reasonable sale-of-business non-competes.

The seller’s lever is scope. Tighter geography, shorter duration, and carveouts for passive investments under 5% are all standard asks. A non-compete that bars the seller from any work in HVAC anywhere in the United States for 10 years is unenforceable in most jurisdictions and will be struck or blue-penciled.

9. Transition Services

A Transition Services Agreement (TSA) is a separate exhibit that lays out what the seller (or the seller’s affiliated entities) will continue to provide post-closing and at what cost. In a small HVAC asset deal, the TSA might cover the owner’s continued availability for customer introductions, payroll system run-out, and IT migration for 30 to 180 days at a stated hourly rate or fixed monthly fee. Larger carve-outs from corporate parents can run 12 to 24 months and cover accounting, HR, IT, procurement, and real estate.

10. Employment and Benefits

This clause addresses which employees transfer, on what terms, with what benefits, and who carries pre-closing employment liabilities. In an asset deal, the buyer hires employees as new hires (with continuity of service credit) and the seller terminates them at closing. In a stock deal, employment continues automatically. WARN Act notice obligations (60 days for plant closings or mass layoffs of 50+ employees at a single site) sit with whoever the employer is at the trigger date, and that allocation needs to be explicit.

Owner employment is its own subclause. If the seller is staying on as an employee or consultant, a separate employment agreement or consulting agreement attaches as an exhibit, with its own term, compensation, benefits, termination triggers, and confidentiality obligations. Earnout participation often runs through this employment relationship.

11. Tax Matters

The tax clause covers (a) purchase price allocation under Internal Revenue Code Section 1060 for asset deals, (b) any Section 338(h)(10) or Section 336(e) election for stock deals treated as asset deals for tax purposes, (c) responsibility for pre-closing tax returns and audits, (d) cooperation on tax filings, and (e) transfer taxes. The allocation is where the buyer and seller have opposite preferences: the buyer wants more allocated to depreciable assets and inventory for fast write-offs, the seller wants more allocated to goodwill and personal goodwill for capital gains treatment.

A Section 338(h)(10) election on a stock deal lets the buyer get a step-up in asset basis while the seller pays at ordinary plus capital gains rates as if the assets had been sold. The seller is usually compensated for the extra tax with a gross-up. The deal team should model the tax impact at LOI stage, not in the definitive agreement, but the documentation lands here.

12. Dispute Resolution and Governing Law

The parties pick a governing law (most often Delaware for SPAs and merger agreements, often the seller’s state for smaller APAs) and a forum (state or federal court, or arbitration). Working capital disputes are typically carved out to a designated independent accounting firm acting as expert. Indemnification disputes default to the chosen forum. Buyers in middle market deals often prefer Delaware Chancery for its M&A expertise and speed; sellers often prefer their home state for cost and convenience.

13. Confidentiality and Public Announcements

The confidentiality clause carries forward the obligations of the original NDA and extends them to the deal terms themselves. The public announcement clause governs press releases and customer communications. In lower middle market deals, most parties agree to a joint press release after closing and to coordinate any pre-closing communications to employees, customers, and vendors. Premature disclosure can spook customers and trigger contract change-of-control reviews before the buyer is ready.

14. Signature and Closing Deliveries

The signature block and the closing deliveries schedule are the operational checklist for the closing call. Closing deliveries typically include the signed agreement, the escrow agreement, the bill of sale (asset deal) or stock power and certificates (stock deal), assignments of contracts and intellectual property, lien releases, payoff letters for assumed or paid-off debt, officer’s certificates bringing down the reps, secretary’s certificates with resolutions, FIRPTA certificates, IRS forms (W-9, Form 8594 allocation), and the closing flow of funds memo. A missed lien release or a misaddressed wire instruction can hold a closing by 24 to 72 hours, which is why a pre-closing checklist call 5 to 10 business days before closing is standard practice.

Worked Example: $25M HVAC Asset Purchase Scaffold

Consider a fictional Texas HVAC business, Smith Mechanical Services, Inc., owned by John Smith. The business has $18M in revenue, $4.2M in adjusted EBITDA, and a signed LOI at 6.0x EBITDA from a private equity-backed strategic, Acme HVAC Holdings, LLC. Headline price $25.2M, asset deal, all-cash at closing with escrow.

The $25.2M headline becomes $22.2M of cash at closing. The $3M sitting in escrow is real seller money, but the seller’s downside is capped at the $2.52M indemnity ceiling for general rep breaches (plus the $1.5M working capital escrow, refundable based on the post-closing true-up). RWI was discussed but skipped because the policy quote at $200K of premium did not justify the savings on the cap. Per Capstone Partners 2026 data, deals under $30M skip RWI roughly 70% of the time.

The working capital target is set at the trailing 12-month monthly average, calculated as accounts receivable (net of a 90-day aging reserve consistent with historical books) plus inventory (at lower of cost or market, valued on FIFO consistent with the audit) plus prepaids, minus accounts payable, accrued expenses, and customer deposits. An illustrative schedule using March numbers is attached to the agreement as Exhibit C. The agreed dispute mechanic sends any disagreement to a designated Big Four accounting firm acting as expert, with each side bearing 50% of the fees unless the firm rules entirely in one side’s favor.

The non-compete is 4 years, the entire State of Texas plus a 50-mile radius into Oklahoma and Louisiana, with carveouts for passive investments under 3% in publicly traded companies and for the owner’s existing rental property business. The seller stays on for 18 months as a W-2 employee at $250,000 salary plus a $50,000 transition bonus payable at the 12-month mark, with severance equal to 6 months of base salary if terminated without cause.

Common Mistakes

Treating the LOI as the Real Deal

The LOI sets the headline, but the definitive agreement is where 5% to 15% of headline value typically moves. Owners who go quiet between signing the LOI and reading the first draft of the APA are the ones who get surprised by aggressive working capital targets, broad reps, and short baskets. The right move is to brief the LOI terms to deal counsel immediately and pre-draft acceptable ranges for cap, basket, and escrow.

Signing Reps the Owner Has Not Read

The seller representations and warranties section is 15 to 25 pages of fine-grained statements about the business, and any one that is materially wrong creates an indemnity claim post-closing. Owners who delegate the reps review entirely to counsel without reading them line-by-line miss disclosures they should have made. The disclosure schedules are the place to surface anything that would otherwise be a breach: the pending customer complaint, the contract with a 30-day termination right, the employee classification audit, the unpatched data incident.

Missing the Working Capital Trap

A target working capital set 10% to 15% above true normalized levels is the single most common way a buyer recovers $500K to $1.5M after closing on a middle market deal. Owners should require an illustrative schedule, the same accounting methods as the historicals, and a fast expert-based dispute mechanism. The phrase “consistent with past practice” is doing a lot of work and should be defined.

Underestimating the Indemnification Cap

A 10% cap on a $25M deal is $2.5M of real risk, payable from escrow first and then from the seller’s pocket. Fundamental reps (organization, authority, title, taxes) are usually uncapped or capped at the full purchase price. Owners should understand which reps are fundamental, which are general, and which sit outside the cap entirely (fraud, certain tax matters, specific indemnities). A bring-along of representation and warranty insurance can shift most of the general rep risk off the seller for a 3% to 4% premium of the policy limit.

Forgetting the Tax Allocation Trade

The Form 8594 allocation is filed with the IRS by both parties and must agree. The buyer’s preference (more to depreciable assets and inventory for fast write-offs) hurts the seller (more ordinary income). The seller’s preference (more to goodwill and personal goodwill) helps the seller (long-term capital gains) and the buyer (15-year amortization). The trade is real money. On a $25M deal, a $3M shift in allocation between equipment and goodwill can move $400K to $700K of after-tax proceeds to the seller, depending on marginal rate brackets.

Ignoring Third-Party Consents

Most material customer contracts, real property leases, equipment financing, and licenses have change-of-control or assignment provisions that require counterparty consent. In an asset deal, every assigned contract needs a consent; in a stock deal, only change-of-control contracts need attention. A missed consent on a top-5 customer contract is a closing condition failure. Owners should pull the consent list during diligence, not at the closing checklist call.

Timeline and Process

The definitive agreement is drafted, redlined, and signed on a predictable cadence once the LOI is in hand.

1. Days 1-15 (post-LOI): Buyer’s counsel prepares first draft of APA or SPA from the firm’s precedent, reflecting LOI terms. Seller’s counsel prepares disclosure schedule template and circulates to seller for population.
2. Days 15-30: First draft delivered to seller’s counsel. Seller’s counsel review and first redline. Disclosure schedules in first draft from seller.
3. Days 30-50: Redline round 2, all-hands negotiation call on major open issues (cap, basket, survival, working capital target, non-compete scope, MAC carveouts). Buyer’s diligence continues in parallel.
4. Days 50-75: Redline rounds 3 and 4, narrowing open issues. Schedules refined as diligence completes. RWI underwriting if applicable.
5. Days 75-90: Final redline. Signing. If signing and closing are simultaneous, closing follows on the same day. If split-sign, the gap to closing runs another 30 to 60 days for regulatory clearance and consents.
6. Days 90-120: Closing call, funds flow, escrow funded, ancillary documents signed (employment agreement, TSA, escrow agreement, bill of sale, assignments).
7. Post-closing (months 1-24): Working capital true-up at 60 to 90 days, indemnity escrow released at 18 months, indemnity claims (if any) prosecuted under the agreement’s dispute mechanic.

Frequently Asked Questions

What is the difference between an APA and an SPA?

An Asset Purchase Agreement transfers specific assets and assumes specific liabilities, leaving the legal entity with the seller. A Stock Purchase Agreement transfers the equity of the entire legal entity, so the buyer inherits all liabilities, known and unknown, except as allocated through indemnification. Asset deals are more common in lower middle market because they let the buyer step up basis and cherry-pick liabilities. Stock deals are more common in regulated industries where transferring licenses and permits is impractical.

Do I need a lawyer for the definitive agreement?

Yes. The contract is the legally binding instrument that transfers a business worth millions of dollars and allocates millions more in post-closing risk. Owners should retain experienced M&A counsel as soon as the LOI is in hand, not when the first draft of the APA lands. The legal fee on a $25M middle market deal typically runs $80,000 to $200,000 on the seller side, depending on complexity and number of redline rounds.

How long is a typical APA or SPA?

For a lower middle market deal at $5M to $50M enterprise value, the main body of the agreement runs 60 to 110 pages, plus 100 to 400 pages of disclosure schedules and exhibits. Larger deals with carve-outs, multiple jurisdictions, or regulatory complexity can exceed 250 pages of main body. The ABA Mergers and Acquisitions Committee model APA in its standard form (without disclosure schedules) runs 95 pages.

What is a Material Adverse Change clause?

A MAC clause is a closing condition that lets the buyer walk if the target business suffers a significant deterioration between signing and closing. Delaware courts apply a high bar, requiring a durationally significant decline in earnings power, not a short-term blip. Most middle market deals include MAC carveouts for industry-wide events, general economic conditions, changes in law, and pandemics. The clause exists primarily as risk allocation language; it is invoked successfully in court only in extreme cases.

What happens if the buyer breaches the agreement before closing?

The seller’s remedies depend on the contract. Most middle market deals provide for specific performance (a court order compelling the buyer to close) plus damages. Some include a reverse termination fee (a flat dollar amount the buyer pays if it walks for non-permitted reasons). Specific performance is hard to enforce against a financial buyer with no operating business to attach, which is why a meaningful reverse termination fee is worth negotiating in sponsor deals.

Should I push for representation and warranty insurance?

For deals above $30M enterprise value, RWI usually pencils. The seller gets a clean exit with most general rep risk transferred to an insurer for a retention typically around 0.75% to 1% of enterprise value. The buyer gets a deeper-pocketed counterparty and faster claim resolution. For deals under $20M, the policy premium and underwriting cost (combined $250,000 to $400,000) often does not justify the savings. CT Acquisitions can model the RWI tradeoff on an owner’s specific deal at no cost.

How CT Acquisitions Approaches This

CT Acquisitions is buyer-paid. Sellers pay nothing for the advisory work. The firm has reviewed and negotiated more than 200 definitive agreements across HVAC, plumbing, electrical, MEP, landscaping, and other home services verticals, and the team walks owners through every clause in plain English before redlines start. Owners come into the negotiation knowing the SRS Acquiom benchmarks, the typical landing zones on cap and basket, and the trade-offs on working capital target and non-compete scope.

The firm does not replace the owner’s deal counsel. The lawyer is essential. CT Acquisitions sits next to the owner during contract negotiation and translates between the legal vocabulary and the business decision. When the buyer’s first draft proposes a 24-month survival and a 0.5% tipping basket, the owner already knows that 18 months and a 0.75% deductible is the standard counter, and what each move is worth.

What to Do Next

The definitive agreement is the document that closes the deal and allocates the post-closing risk. It is also the document where a thoughtful seller can recover meaningful value from an opportunistic first draft. Owners who walk into contract negotiation cold lose ground. Owners who walk in with the benchmarks and the playbook close on terms that reflect the value of the business they built.

Nothing in this guide is legal advice. Definitive agreements should be drafted and negotiated by qualified counsel familiar with the owner’s jurisdiction, industry, and specific deal context.
