Equity Purchase Agreement: When to Use an EPA vs SPA vs APA

An equity purchase agreement is the master contract that transfers ownership of a company by selling the seller’s equity interests, rather than the underlying assets or, in a corporate context, the issued stock. The term “equity purchase agreement” is the umbrella label used across US private M&A when the target is a limited liability company, limited partnership, or other pass-through entity whose ownership is denominated in membership interests, partnership units, or LLC units rather than in shares of stock. According to the ABA Private Target Mergers and Acquisitions Deal Points Study 2024, which analysed 116 transactions signed in 2023 with deal values between $30m and $750m, equity sales now account for the majority of US private mid-market deals because the most common US target form is an LLC, not a C-corporation.
This guide breaks down the equity purchase agreement structure clause by clause, contrasts it against the stock purchase agreement (SPA, used for C-corporations and S-corporations) and asset purchase agreement (APA, used when the buyer wants a clean basis step-up without inheriting entity-level liabilities), and shows where the document deviates from a vanilla SPA in ways that matter for tax, indemnity, and signing logistics. If you are a sell-side advisor, buy-side principal, GC, or tax counsel running a deal where the target is an LLC, this is the operator-level reference for getting the EPA right.
Equity Purchase Agreement at a Glance: Quick-Reference Table
Before drilling into individual clauses, here is the structural map of a typical US-style equity purchase agreement on a mid-market LLC sale. Section ordering varies by firm precedent (Kirkland & Ellis, Latham & Watkins, Cooley, Goodwin, Sidley, and Wachtell all maintain proprietary form EPAs), but the substantive content below appears in every market-standard agreement.
| Section | Typical Length | What it Does | Most-Negotiated Items |
|---|---|---|---|
| 1. Definitions | 15-30 pages | Defines every capitalized term used downstream | Indebtedness, Net Working Capital, Material Adverse Effect, Knowledge, Permitted Liens, Transaction Expenses |
| 2. Purchase and Sale of Equity Interests | 1-2 pages | Transfers the LLC units or partnership interests | Whether sale is on a fully diluted basis, treatment of phantom units |
| 3. Purchase Price and Closing | 4-10 pages | Fixes the price, escrow, holdback, true-up mechanism | NWC peg, indebtedness sweep, escrow size, R&W insurance retention |
| 4. Conditions to Closing | 2-5 pages | What must happen before closing | HSR clearance, CFIUS, key customer consents, bring-down standard |
| 5. Pre-Closing Covenants | 3-8 pages | How seller runs the business between signing and closing | Ordinary-course definition, prohibited-action list, consent thresholds |
| 6. Representations and Warranties of Sellers / Company | 20-50 pages | Statements of fact about the target | Knowledge qualifiers, 10b-5 rep, full disclosure rep, scheduled exceptions |
| 7. Representations and Warranties of Buyer | 2-4 pages | Capacity, authority, funds available, no consents required | Sufficiency of funds, sponsor equity commitment letter |
| 8. Indemnification | 8-15 pages | Caps, baskets, survival periods, exclusive remedy | Indemnity cap, basket type (tipping vs deductible), survival period, fraud carve-out |
| 9. Tax Matters | 10-25 pages | Allocation, pre-closing returns, refunds, transfer taxes | Section 754 election, push-out election (BBA), straddle period allocation, tax-distribution true-up |
| 10. Restrictive Covenants | 2-4 pages | Non-compete, non-solicit on rollover sellers | Duration (3-5 years), geographic scope, blue-pencil mechanics post-FTC vacatur |
| 11. Termination | 2-3 pages | Walk rights, drop-dead date, fees | Outside date, reverse termination fee size, specific performance |
| 12. Miscellaneous | 5-10 pages | Governing law, jurisdiction, notices, assignment, expenses | Delaware vs New York choice of law, jury trial waiver, third-party beneficiaries |
Total page count for a US EPA on a $50m-$500m LLC deal: 80-160 pages excluding schedules. Add 150-300 pages of disclosure schedules and the R&W policy and you are at a 600-page closing bundle. The Skadden 2024 M&A Insights Report noted median time from LOI to signing on US sponsor-led equity deals stretched to 91 days in 2023, up from 76 in 2022.
Equity Purchase Agreement vs Stock Purchase Agreement vs Asset Purchase Agreement
The three transaction documents look superficially similar and trip up first-time deal participants. Picking the wrong form has multi-million dollar tax and indemnity consequences. Understand the distinctions before reading another clause.
| Feature | Equity Purchase Agreement (EPA) | Stock Purchase Agreement (SPA) | Asset Purchase Agreement (APA) |
|---|---|---|---|
| Used when target is | LLC, LP, LLP, or other pass-through entity | C-corporation or S-corporation | Any entity, when buyer wants specific assets only |
| What transfers | Membership interests, partnership units, LLC units | Issued and outstanding shares of capital stock | Specifically scheduled assets and assumed liabilities |
| Liabilities | All historic liabilities follow the entity | All historic liabilities follow the corporation | Only assumed liabilities pass; the rest stay with seller |
| Seller tax treatment | Pass-through capital gain (assuming partnership for tax) | Capital gain at shareholder level; double tax avoided | Asset-level gain (ordinary on inventory, capital on goodwill) plus entity-level tax for C-corps |
| Buyer basis step-up | Yes, automatically under IRC Section 743(b) if 754 election in place; deemed asset purchase under Treas. Reg. 1.708-1 | No step-up unless 338(h)(10) or 336(e) election | Step-up to purchase price allocation under IRC Section 1060 |
| Goodwill amortization for buyer | Yes, 15-year amortization under IRC Section 197 | No unless 338(h)(10) | Yes, 15-year amortization under IRC Section 197 |
| Third-party consents required | Limited (LLC operating agreement transfer restrictions) | Limited (charter or stockholder agreement restrictions) | Extensive (every assigned contract, lease, permit) |
| Transfer tax exposure | Low in most states; controlling interest transfer tax in NY, CT, MD, NJ, DC, MI | Generally none at federal level | Sales and use tax on tangible assets; real estate transfer tax on owned real property |
| Bulk sales law applies | No (entity continues) | No (entity continues) | Yes in California (CA Commercial Code Div. 6); UCC Article 6 repealed in 47 other states |
| Document length | 80-160 pages | 70-140 pages | 100-180 pages |
The EPA dominates US mid-market M&A because the LLC has been the default US private-company entity since the IRS issued the check-the-box regulations under Treas. Reg. 301.7701-3 in 1997. Per the IRS Statistics of Income Partnership Returns 2023, 4.8 million LLCs filed Form 1065 partnership returns for tax year 2022. The LLC wins for pass-through tax treatment, single-class flexibility, and a contractually customizable operating agreement.
When the target is a C-corp, you want a stock purchase agreement (our stock purchase agreement guide covers it). When the buyer wants only specific assets, use an APA. For everything in between, the EPA is the dominant document.
Why Buyers Often Prefer an EPA Over a Stock Purchase Agreement
Buyers who can choose between an EPA and an SPA prefer the EPA when the target is an LLC because of one tax feature: the automatic basis step-up. Under IRC Section 743(b), when a partnership interest is purchased and the partnership has a valid Section 754 election, the buyer steps up inside basis to fair market value. The step-up generates depreciation and amortization deductions for the buyer over 5 to 15 years.
On a $100m EV deal where $70m of consideration is allocable to amortizable goodwill and intangibles, the buyer captures roughly $4.67m of additional annual amortization for 15 years. At a 25% effective tax rate, that is $1.17m per year of cash tax savings, or a present value of $9-12m discounted at 8-10%. The Tax Adviser, May 2024 walked through this dynamic on a $250m PE secondary.
In a vanilla stock purchase of a C-corp, the buyer gets no step-up unless the parties make a Section 338(h)(10) or Section 336(e) election. Both require the seller to recognize an asset-level gain, which the seller will not agree to without a gross-up. The gross-up math is rarely favorable.
This is why sponsor buyers frequently pay a 50-150 basis point higher multiple for an LLC than for an identical C-corp target. Bain & Company’s Global Private Equity Report 2024 documented this premium across 412 sponsor-led mid-market deals in 2022-2023, averaging 9% of EV on add-ons. For the valuation math, see our DCF business valuation guide and business valuation formula deep dive.
Section 2: Purchase and Sale of Equity Interests
The operative transfer clause: two pages of text, three weeks of negotiation. It reads in substance, “At Closing, Sellers shall sell, transfer, convey, assign, and deliver to Buyer all of Sellers’ right, title, and interest in and to the Equity Interests, free and clear of all Liens (other than federal and state securities law restrictions), for the consideration in Article III.”
Three drafting battles dominate:
Fully diluted treatment of equity
The buyer wants confirmation the Equity Interests represent 100% of the fully diluted cap table, including options, warrants, profits interests, convertible notes, SAFEs, and phantom units. The seller’s cap table gets cleaned up pre-signing so the EPA references an attached capitalization schedule listing every holder and unit count.
Profits interests and 83(b) treatment
Many LLC-form targets have issued Section 83(b) profits interests to executives. At closing, these convert to capital interests entitled to consideration. The EPA needs explicit mechanics for closing cancellation or exchange, tax treatment of any deemed compensation event, and whether the holder’s gain is capital (per Rev. Proc. 93-27) or ordinary.
Rollover equity mechanics
Sponsor buyers frequently require management to roll over 10-30% of after-tax proceeds into the buyer’s acquisition vehicle. The EPA references a separate rollover agreement and contribution agreement, and the cash portion to rollover sellers is reduced accordingly. Get the rollover mechanics wrong and you create a partial sale that triggers profits-interest vesting acceleration or 280G golden-parachute issues. See our golden parachute 280G primer.
Section 3: Purchase Price, Net Working Capital, and the Closing Funds Flow
The Purchase Price section sets the headline number, defines the closing-day mechanics, and codifies the post-closing true-up. This is the second most contested section of the agreement after the indemnification article. The four moving pieces:
- Base Purchase Price. The headline enterprise value agreed at signing.
- Adjustments at Closing. Plus closing cash, minus closing indebtedness, plus or minus the difference between estimated closing Net Working Capital and the agreed NWC target (the “peg”), minus unpaid transaction expenses, minus the escrow holdback.
- Estimated Closing Statement. Delivered by sellers 3-5 business days before closing, containing seller’s good-faith estimate of each adjustment item.
- Post-Closing True-Up. Buyer delivers a Final Closing Statement within 60-90 days of closing; disputes go to an independent accountant whose determination is binding.
| Adjustment Item | Direction | Typical Negotiation Battle |
|---|---|---|
| Closing Cash | Plus to purchase price | Definition of restricted cash, trapped foreign cash, customer deposits |
| Closing Indebtedness | Minus from purchase price | Capitalized leases (ASC 842), pension underfunding, tax accruals, deferred compensation, transaction bonuses |
| Net Working Capital vs Peg | Plus or minus | The peg itself (12-month rolling average is typical), what is in vs out of the calculation, accounting policies |
| Unpaid Transaction Expenses | Minus from purchase price | Definition of “Transaction Expenses” (advisor fees, success bonuses, D&O tail premium, R&W policy retention) |
| Escrow / Holdback | Held back from cash to sellers | Size (typically 0.5-2% of EV for R&W backed deals, 5-15% for non-insured deals), release schedule |
The Net Working Capital peg is the single most negotiated number in the EPA. The AICPA Forensic and Valuation Services 2024 practice guide noted NWC disputes accounted for 47% of post-closing M&A disputes referred to expert determination. The peg is conventionally a 12-month rolling average of actual NWC, calculated on the same accounting policies producing the closing statement. Get the policies wrong (cash vs accrual on a specific item, classification of deferred revenue, treatment of bad-debt reserve) and the buyer gets a windfall or the seller gets stiffed.
The EPA references a Closing Funds Flow Memorandum signed by both parties and the paying agent. It schedules cash to each seller per the cap table, payoff wires to lenders, transfer to escrow agent, payment of transaction expenses, and contribution from buyer’s debt and equity sources. Funds-flow arithmetic errors are the leading cause of failed wires on closing day.
Section 4: Conditions to Closing and the Bring-Down Standard
Conditions to closing are the events that must happen before either party is obliged to close. Standard buyer conditions: HSR clearance (Hart-Scott-Rodino under 15 U.S.C. Section 18a, required above the FTC’s $126.4m 2025 size-of-transaction threshold per the FTC Premerger Notification Office, January 2025); CFIUS clearance for non-US buyers in covered sectors under 31 CFR Part 800; key consents; bring-down of reps; no Material Adverse Effect; officer’s certificates.
The bring-down standard for reps is one of the three most fought-over points in the EPA. Three variants in market use:
| Bring-Down Standard | What it Means | Who it Favors | 2023 ABA Deal Points Frequency |
|---|---|---|---|
| “Accurate in all respects” | Any breach, however minor, fails the condition | Buyer (rare) | 4% |
| “Accurate in all material respects” | Materiality applied breach by breach | Buyer-friendly | 11% |
| “Accurate except where failure would not constitute an MAE” | Materiality applied in aggregate to the MAE standard | Seller-friendly | 85% |
The MAE-double-materiality formulation (the 85% market standard) means the buyer cannot walk for a single material breach if it would not, in aggregate, constitute a Material Adverse Effect on the target. The MAE standard itself is interpreted narrowly by Delaware courts. The seminal case is Akorn, Inc. v. Fresenius Kabi AG, 2018 WL 4719347 (Del. Ch. Oct. 1, 2018), the only Delaware decision finding an MAE in a public-company merger. The court required a “durationally significant” deterioration measured in years, not quarters. Most MAE arguments fail. For the broader doctrine, see our material adverse effect guide.
Section 6: Representations and Warranties of the Sellers and the Company
Representations are statements of fact about the target. If a rep is untrue at signing and again at closing (per the bring-down standard), the buyer can refuse to close or claim indemnification post-closing. This is the largest section of the EPA, typically 60-150 numbered reps grouped into categories.
Standard category list on a US mid-market EPA: organization and power; capitalization; authority; financial statements (GAAP, ASC 606 revenue, ASC 842 leases, ASC 326 credit losses); absence of changes; compliance with laws (including FCPA, OFAC, AML); material contracts; ERISA and employee benefit plans; tax; intellectual property (including open-source contamination); litigation; real property; environmental (CERCLA, Phase II); insurance; top customers and suppliers; privacy and data security (GDPR, CCPA, HIPAA).
The 10b-5 representation
The most fought-over rep is the “10b-5 rep,” which the buyer wants and the seller resists: no untrue statement of material fact, no omission of a material fact needed to make the statements not misleading. It effectively makes the EPA a Rule 10b-5 securities-fraud-grade disclosure document, expanding seller exposure beyond the itemized reps. The ABA 2023 Deal Points Study found 21% of mid-market EPAs included a full 10b-5 rep, 38% a knowledge-qualified version, and 41% excluded it entirely. The trend is strongly downward as R&W insurance has become standard.
Knowledge qualifiers
Some reps are given “to the Sellers’ Knowledge” or “to the Knowledge of the Company.” If the seller did not know about the breach, no indemnification. The buyer wants no knowledge qualifier; the seller wants them on every rep. The market compromise defines “Knowledge” precisely (actual knowledge of named persons after reasonable inquiry) and confines knowledge qualifiers to reps where seller visibility is legitimately limited: third-party IP infringement claims, environmental conditions in formerly owned properties, customer-disclosed information.
Section 8: Indemnification, the Sandbag Clause, and R&W Insurance
The indemnification section sets out what happens if a representation turns out to be false. The architecture has four pieces: cap, basket, survival, and exclusive remedy.
| Element | Mechanic | 2023 ABA Market Median |
|---|---|---|
| Cap on indemnification | Maximum recovery for breaches of general reps | 10% of purchase price for non-insured deals; 0.5-1% for R&W insured deals (matched to retention) |
| Basket / deductible | Threshold below which no claim is paid | 0.75% of EV (deductible); 0.5% (tipping basket) |
| De minimis | Per-claim minimum (excludes nuisance claims) | $25k-$100k depending on deal size |
| Survival of general reps | How long the buyer has to bring a claim | 12-18 months (non-insured); 6 years for R&W policy |
| Survival of fundamental reps | Cap and tax reps, title to equity, capitalization, authority | Statute of limitations |
| Exclusive remedy | Are damages capped at the indemnification cap, or can buyer sue at common law? | Exclusive remedy except fraud (95% of deals) |
| Fraud carve-out | What constitutes “fraud” for exclusive-remedy purposes | Narrowly defined as “Delaware common-law fraud with intent to deceive” (66% of deals); broader definitions losing ground |
Rep and warranty insurance transformed this section. The Marsh Transactional Risk 2024 Report noted 76% of US private M&A above $50m placed R&W insurance in 2023, up from 31% in 2017. With insurance in place, the seller cap drops to 0.5-1% of EV, matching policy retention.
The sandbagging clause
“Sandbagging” describes a buyer who knows at signing that a seller representation is false but says nothing, closes the deal, and then claims indemnification post-closing. Whether this is allowed depends on the contract and the governing law. Three variants in market:
- Pro-sandbag clause. “Buyer’s rights to indemnification shall not be affected or diminished by any investigation conducted or any knowledge acquired by Buyer.” 49% of 2023 ABA deals.
- Anti-sandbag clause. “Buyer shall not be entitled to indemnification for any matter of which Buyer had actual knowledge prior to Closing.” 10% of 2023 ABA deals.
- Silent on sandbagging. 41% of 2023 ABA deals. Delaware default rule is pro-sandbag per Eagle Industries, Inc. v. DeVilbiss Health Care, Inc., 702 A.2d 1228 (Del. 1997), holding the buyer can rely on the express contractual reps regardless of pre-closing knowledge.
If you are buy-side, push for the express pro-sandbag clause. If you are sell-side, push for the express anti-sandbag clause or rely on R&W insurance carve-outs for matters disclosed in the diligence data room.
Section 9: Tax Matters and the Section 754 Election
The Tax section runs 10-25 pages and is the single most technical part of the document. The headline provisions:
Section 754 election
The EPA requires the Company to make a valid election under IRC Section 754 for the taxable year of closing so the buyer obtains the Section 743(b) inside-basis step-up. If the Company never previously made one, a clean Section 754 election gets filed with the partnership return for the year of sale. Failure to file by the due date of the return (including extensions, per Treas. Reg. 1.754-1) costs the buyer the step-up, a potentially seven-figure penalty.
BBA push-out election
The Bipartisan Budget Act of 2015 replaced TEFRA with a centralized partnership audit regime under which the partnership itself pays an imputed underpayment for any post-closing IRS adjustment to a pre-closing year. The EPA forces a “push-out election” under IRC Section 6226 so any pre-closing-year adjustment is pushed out to the historic partners (sellers) rather than borne by the post-closing partnership now owned by the buyer.
Straddle period and transaction deductions
For Straddle Periods, income taxes get allocated on a “closing of the books” basis; property and other periodic taxes pro rata by days. Transaction expenses paid by the Company at closing (success fees, sale bonuses) generate deductions; the EPA allocates these to the pre-closing year so sellers benefit, applying the Next Day Rule of Treas. Reg. 1.1502-76(b)(1)(ii)(B) by analogy.
Transfer taxes
Several states impose a “controlling interest transfer tax” on equity sales of entities owning state real estate. New York imposes 0.4% on transfers above 50% per NY Tax Law Section 1402; Connecticut, Maryland, New Jersey, DC, and Michigan have similar regimes. The EPA market default is 50-50 allocation, but the negotiation matters on real-estate-heavy targets.
Section 10: Restrictive Covenants After the FTC Non-Compete Rule
Restrictive Covenants bind rollover sellers (management staying with the buyer) and cashed-out sellers not to compete or solicit employees post-closing. Typical terms: 3-5 year duration, geographic scope matched to where the target operates, “Competing Business” defined by product or service lines.
The landscape shifted in 2024-2025. The FTC’s final rule banning most non-competes at 89 Fed. Reg. 38342 (May 7, 2024) was vacated nationwide by Judge Ada Brown in Ryan LLC v. FTC, N.D. Tex. Aug. 20, 2024, with the FTC’s appeal pending in the Fifth Circuit as of mid-2026. The rule contained a sale-of-business exception at 16 CFR Section 910.3(a) exempting non-competes “entered into by a person pursuant to a bona fide sale of a business entity,” so EPA non-competes survive by design. State law is the binding constraint. California, North Dakota, Oklahoma, and Minnesota restrict non-competes generally but permit them in sale-of-business contexts under California Business and Professions Code Section 16601 and similar statutes. Use a blue-pencil severability clause so an unenforceable provision in one state does not invalidate the rest.
Section 11: Termination, the Outside Date, and Reverse Termination Fees
The Termination section sets out when, and on what terms, either party can walk away from the EPA before closing. The standard termination triggers:
- Mutual written consent
- Outside Date (the “drop-dead date,” typically 6-9 months from signing) without closing having occurred
- Material uncured breach by the other party
- Permanent denial of a required regulatory approval (HSR Second Request leading to FTC challenge, CFIUS prohibition)
- Failure of a closing condition that cannot be satisfied
If the buyer is a sponsor walking on financing failure or willful breach, the seller normally negotiates a “Reverse Termination Fee” (RTF) payable by the buyer. RTF sizes have crept up over time. The Sidley 2024 M&A Jurisprudence Update noted median RTFs of 6.5% of equity value for sponsor-led deals in 2023, with regulatory-only RTFs at the lower end (3-4%) and financing-failure RTFs at the upper end (7-9%).
Specific performance is the other major termination question. Most sponsor-buyer EPAs cap the seller’s remedy at the RTF and exclude specific performance entirely. Corporate buyer EPAs more often allow specific performance to force closing once financing is in place. The Delaware Court of Chancery enforced specific performance against a financing-funded corporate buyer in Snow Phipps Group, LLC v. KCAKE Acquisition, Inc., 2021 WL 1714202 (Del. Ch. Apr. 30, 2021), where the court ordered Kohlberg to close on its KCAKE acquisition during the COVID-19 disruption.
Worked Example: $150m LLC Sale Funds Flow
Worked closing funds-flow on a hypothetical $150m enterprise value sale of a portfolio LLC by a sponsor seller to a strategic buyer. The numbers show where every dollar moves on closing day.
| Line Item | Amount ($m) | Notes |
|---|---|---|
| Enterprise Value (base purchase price) | 150.0 | Agreed at signing |
| Plus: Closing Cash (estimate) | +8.5 | Unrestricted cash on hand |
| Less: Closing Indebtedness | -42.0 | Senior debt $35m + capitalized leases $7m |
| Less: Unpaid Transaction Expenses | -4.2 | Sell-side advisor 1.5%, legal $1.0m, success bonuses $0.95m |
| Plus/Less: NWC vs Peg | +1.3 | Estimated NWC $24.8m vs $23.5m peg |
| Estimated Equity Value at Closing | 113.6 | Cash and stock consideration to all equity holders |
| Less: Indemnity Escrow | -1.5 | 1% of EV (R&W insured deal) |
| Less: NWC Adjustment Escrow | -0.8 | $0.8m held for 90 days pending true-up |
| Cash to Sellers at Closing | 111.3 | Wired per cap table on Schedule 3.1 |
| Of which: Rollover Equity | -22.3 | 20% of cash to management rolled into buyer NewCo |
| Net Cash to Cashing-Out Sellers | 89.0 | Final wire amount |
The estimate is settled 60-90 days post-closing via the final closing statement and true-up payment. Any dispute runs through expert determination by an independent accountant named in the EPA. Bain & Company’s Global M&A Report 2024 reported closing-statement disputes go to expert determination in roughly 8% of US private deals and average 5 months to resolve.
The R&W Insurance Layer Sitting Underneath the EPA
Rep and warranty insurance is now the default backstop on US mid-market EPAs. Standard policy structure: named insured is Buyer in 90% of policies; policy limit typically 10% of enterprise value; retention 0.5-1% of EV for the first 12 months dropping to 0.5% thereafter; premium 2.5-4% of policy limit, down from 3.5-5% in 2022 per the Aon Transaction Solutions 2024 R&W Insurance Market Report. Exclusions: known matters (anything in the data room or disclosure schedules), purchase price adjustments, specific covenants, transfer pricing and NOL tax matters. Survival: 3 years for general reps, 6 years for tax and fundamental reps.
With insurance in place, the seller-indemnification cap drops to 0.5-1% of EV (matched to policy retention), the basket is sized to the same number, and the insurer picks up losses above retention up to the policy limit. Sellers’ indemnification exposure shrinks from 10% (uninsured median) to 0.5-1% (insured median). That swing is the single most cited reason for placing insurance. Aon’s 2024 report tracked median time from carrier engagement to bound policy at 19 days, down from 28 days in 2021.
The EPA on a Carve-Out Sale: Why Asset Purchase Is Often Required Instead
When a corporate seller is selling a division or business unit that does not sit in its own LLC, the EPA does not work. There is nothing to sell, because the unit’s assets, employees, contracts, and intellectual property are owned by the larger parent entity. Two structuring solutions:
- Pre-sale internal restructuring. The seller drops the division’s assets into a newly formed Newco LLC, then sells the LLC interests in the Newco to the buyer via an EPA. This requires 3-6 months of preparation, third-party consent procurement on any contracts being assigned to Newco, and pre-clearance of the restructuring with tax counsel (the contribution into Newco should qualify as a tax-free contribution under IRC Section 721).
- Asset purchase agreement instead. The buyer simply buys the specified assets via an APA. This avoids the internal restructuring but requires the buyer to negotiate every third-party consent itself, which can be a deal-killer for IT licenses, government contracts, or large customer agreements with anti-assignment clauses.
Sponsor sellers prefer the Newco-and-EPA structure because it transfers the consent risk to the seller pre-closing and produces a cleaner closing. Strategic sellers sometimes prefer the APA structure because it avoids the Newco restructuring cost and lets them retain liabilities they want to keep (e.g., a known environmental issue at a manufacturing site). The decision turns on facts. For a worked comparison, see our installment sale vs cash sale guide, which covers related structuring considerations on the consideration side.
Founder-Specific EPA Issues: QSBS, Profits Interests, and Section 1202
When the target was originally a C-corp but converted to an LLC pre-sale, the EPA needs to address whether IRC Section 1202 qualified small business stock treatment is preserved. Section 1202 allows a 100% exclusion of gain (up to the greater of $10m or 10x basis) on QSBS held more than 5 years. C-corp-to-LLC conversion typically destroys QSBS status because the corporation is treated as liquidating. The EPA cannot fix this; pre-sale planning does. If founders held QSBS-qualified shares for 5+ years, preserve the C-corp form and structure the deal as a stock purchase agreement instead.
The One Big Beautiful Bill Act of 2025 increased the Section 1202 cap from $10m / 10x basis to $15m / 15x basis for stock acquired after July 4, 2025, and introduced tiered partial exclusions phasing in from a 3-year minimum holding period. For more, see our QSBS Section 1202 guide and our founder shares primer.
For founders holding LLC profits interests, the EPA should preserve long-term capital gain character. Per Rev. Proc. 93-27 and the safe harbor in Rev. Proc. 2001-43: zero-liquidation-value profits interests held more than 2 years receive LTCG treatment on EPA proceeds. The cap-table schedule must identify each profits interest holder and confirm vesting.
Choice of Law: Why Delaware Dominates
Roughly 80% of US private equity EPAs are governed by Delaware law per the ABA 2023 Deal Points Study; New York governs another 12%. Delaware’s dominance rests on three features: the Court of Chancery hears M&A disputes without juries in front of deal-specialist judges with decisions in months not years; the Delaware LLC Act grants extreme contractual flexibility under 6 Del. C. Section 18-1101(c) (“maximum effect to the principle of freedom of contract”); and Delaware courts enforce indemnification caps, baskets, exclusive-remedy, and forum-selection clauses with high consistency, so the EPA math actually means what it says. New York is the runner-up. California is rarely chosen because its contract law makes anti-sandbagging and non-compete enforcement harder.
Common Mistakes That Cost Money After Closing
Patterns that repeatedly destroy seller value post-closing on EPAs:
- Indebtedness definition omits capitalized leases. Under ASC 842, operating leases sit on the balance sheet as right-of-use assets and lease liabilities. If the indebtedness definition does not explicitly include capitalized lease liabilities, the buyer will argue they belong in Indebtedness and reduce the purchase price by 6-7 figures.
- NWC peg set on cash-basis financials when target uses accrual. The peg has to be calculated on the same accounting basis that produces the closing statement.
- Forgetting the Section 754 election. If the buyer is paying an LLC premium for the basis step-up, the election has to be in place. Verify on the closing certificate.
- R&W policy not bound at signing. The carrier walks if it discovers a material issue between signing and closing. Bind at or before signing, with a 60-day extension to closing.
- 280G analysis skipped. Sale bonuses, retention payments, and change-in-control vesting can trigger 20% excise tax on parachute payments. The seller-side Section 280G shareholder vote needs to happen before closing if the math is tight. Our golden parachute 280G guide walks through the mechanics.
TLDR and Key Takeaways
An equity purchase agreement is the right document when the target is an LLC, LP, or other pass-through entity (most US mid-market companies); when the buyer wants to inherit the entity as a going concern with its contracts, employees, licenses, and historic liabilities; when the buyer values the IRC Section 743(b) basis step-up available with a Section 754 election; and when the parties want a faster, cleaner closing than an asset purchase allows.
Switch to a stock purchase agreement when the target is a C-corp or S-corp. See our stock purchase agreement guide for that form. Switch to an asset purchase when the buyer wants only specific assets or refuses to assume historic liabilities.
The four pieces of the EPA that move the most money post-signing: (1) the Net Working Capital peg and the definitions of Cash and Indebtedness in the purchase price adjustment, (2) the bring-down standard on reps and warranties at closing, (3) the indemnification cap, basket, and survival period (and whether R&W insurance backstops them), and (4) the Section 754 election and BBA push-out election in the tax section. Spend negotiating capital on these four.
For the broader deal context, our M&A advisor guide, sell-side analyst overview, and PE analyst career guide walk through who owns which sections of the EPA. For the underlying valuation math, see our DCF valuation for business sale guide, how to determine the value of a business, and LBO model from scratch tutorial.
The EPA is not a document you read once and shelve. It is the operating manual for the deal for years after closing: every indemnification claim, every escrow release, every tax adjustment, every restrictive covenant enforcement runs back to its text. Get the EPA right at signing and the post-closing phase becomes administration. Get it wrong and the post-closing phase becomes litigation.
