## Articles by category

### Fundamentals

Core concepts: what mergers and acquisitions are, the parties involved, and the strategic rationale behind deals.

- [Acquisition](https://mnapedia.com/wiki/acquisition): The purchase of one company, or its assets, by another that gains control.
- [Add-on acquisition](https://mnapedia.com/wiki/add-on-acquisition): A smaller business acquired by an existing platform company. Also known as a tuck-in or bolt-on; commonly used by private equity to expand a portfolio company.
- [Carve-out](https://mnapedia.com/wiki/carve-out): A partial divestiture in which a parent sells a minority stake in a subsidiary to outside investors via an IPO, while retaining a controlling interest.
- [Consolidation](https://mnapedia.com/wiki/consolidation): A combination in which two firms join to form a new third entity, distinct from a merger in which one company survives.
- [Divestiture](https://mnapedia.com/wiki/divestiture): The sale, spin-off or other disposal of a division, subsidiary or asset by a parent company.
- [Joint venture](https://mnapedia.com/wiki/joint-venture): A new business entity owned by two or more independent companies, used to share costs, capabilities or market access without a full merger.
- [Merger](https://mnapedia.com/wiki/merger): The combination of two companies into a single surviving legal entity.
- [Mergers and acquisitions](https://mnapedia.com/wiki/mergers-and-acquisitions): The umbrella term for transactions that combine the ownership of companies or their assets, and the multi-stage process by which those transactions are negotiated and closed.
- [Platform acquisition](https://mnapedia.com/wiki/platform-acquisition): The first acquisition in a roll-up — typically larger, professionally managed, and used as the operational base for subsequent add-on deals.
- [Reverse merger](https://mnapedia.com/wiki/reverse-merger): A transaction in which a private company becomes publicly traded by merging with an existing public shell company, bypassing the traditional IPO process.
- [Roll-up](https://mnapedia.com/wiki/roll-up): A consolidation strategy in which a buyer acquires many small firms in a fragmented industry to build scale, multiple-arbitrage value and market position.
- [Spin-off](https://mnapedia.com/wiki/spin-off): A divestiture in which a parent distributes the shares of a subsidiary to its existing shareholders, creating a separately listed company.
- [Strategic alliance](https://mnapedia.com/wiki/strategic-alliance): A non-equity cooperation agreement between independent firms — for example a co-marketing, supply or licensing arrangement — distinct from a joint venture or M&A.
- [Synergy](https://mnapedia.com/wiki/synergy): The extra value a combined company can create beyond the sum of the two firms apart.
- [Types of mergers](https://mnapedia.com/wiki/types-of-mergers): Classification of mergers by the economic relationship between the combining firms.

### Valuation

How buyers and advisers estimate what a company is worth — intrinsic and relative methods.

- [Accretion/dilution analysis](https://mnapedia.com/wiki/accretion-dilution-analysis): A test of whether a deal raises or lowers the acquirer’s earnings per share.
- [Asset-based valuation](https://mnapedia.com/wiki/asset-based-valuation): Valuing a business at the net realisable value of its assets minus liabilities. Most relevant for asset-heavy, low-profit or distressed businesses.
- [Business valuation](https://mnapedia.com/wiki/business-valuation): The set of methods used to estimate the economic value of a company or its equity, almost always triangulated across several approaches into a defensible range.
- [Comparable company analysis](https://mnapedia.com/wiki/comparable-company-analysis): Relative valuation using the market multiples of similar publicly traded companies.
- [Control premium](https://mnapedia.com/wiki/control-premium): The extra amount per share a buyer pays to acquire a controlling stake versus the price of a minority interest. Reflects the value of being able to direct the business.
- [Discount for lack of marketability](https://mnapedia.com/wiki/dlom): An adjustment that reduces the value of an illiquid (typically private-company) interest to reflect the fact that there is no ready public market in which to sell it.
- [Discounted cash flow](https://mnapedia.com/wiki/discounted-cash-flow): An intrinsic valuation that discounts a company’s projected cash flows to present value.
- [EBITDA](https://mnapedia.com/wiki/ebitda): Earnings Before Interest, Taxes, Depreciation and Amortization — a measure of a company's operating profitability used as the base for most M&A multiples.
- [EBITDA multiple](https://mnapedia.com/wiki/ebitda-multiple): The ratio of enterprise value to EBITDA, the most common shorthand for what a business is worth in M&A. Industry, scale, growth and quality of earnings all move it.
- [Enterprise value](https://mnapedia.com/wiki/enterprise-value): The total value of a company’s operations, independent of its capital structure.
- [Minority discount](https://mnapedia.com/wiki/minority-discount): A reduction in per-share value applied to non-controlling stakes to reflect the limited rights minority holders have over distributions, sale and operations.
- [Normalization adjustments](https://mnapedia.com/wiki/normalization-adjustments): Adjustments to reported earnings to remove one-time, non-operating or owner-specific items, producing a run-rate EBITDA that better reflects the ongoing business.
- [Precedent transaction analysis](https://mnapedia.com/wiki/precedent-transaction-analysis): Relative valuation using the multiples paid in comparable past acquisitions.
- [Quality of earnings](https://mnapedia.com/wiki/quality-of-earnings): An independent accounting analysis that tests how sustainable, predictable and accurately measured a target's reported earnings are. The QofE is a near-universal pre-LOI deliverable in serious deals.
- [Revenue multiple](https://mnapedia.com/wiki/revenue-multiple): Enterprise value divided by revenue. Used when EBITDA is negative (early-stage, software) or to sanity-check EBITDA-based valuations.
- [Seller's discretionary earnings](https://mnapedia.com/wiki/sde): A small-business profitability measure equal to EBITDA plus owner compensation and discretionary expenses. Standard in lower-middle-market and main-street M&A.
- [Sum-of-the-parts valuation](https://mnapedia.com/wiki/sum-of-the-parts): Valuing each business segment of a company separately and adding the parts. Often used for diversified conglomerates or ahead of a planned spin-off.
- [Terminal value](https://mnapedia.com/wiki/terminal-value): In a DCF, the present value attributed to all cash flows beyond the explicit forecast period — typically the largest single component of total value.
- [Weighted average cost of capital](https://mnapedia.com/wiki/wacc): The blended after-tax cost of a company's debt and equity capital, weighted by their proportions. The standard discount rate used in DCF valuations.

### Deal process

The stages of a transaction, from first contact and diligence to signing and closing.

- [Buy-side M&A process](https://mnapedia.com/wiki/buy-side-ma-process): The deal cycle from the buyer's perspective: thesis development, sourcing, screening, valuation, IOI / LOI, diligence, structuring, financing and closing.
- [Closing checklist](https://mnapedia.com/wiki/closing-checklist): An exhaustive list of conditions, deliverables, signatures, consents and filings required to take a deal from signed agreement to closed transaction. Maintained by deal counsel.
- [Confidential Information Memorandum](https://mnapedia.com/wiki/cim): The detailed marketing document that follows the teaser. Usually 30–80+ pages covering business overview, market, financials, customers, employees and growth opportunities.
- [Data room](https://mnapedia.com/wiki/data-room): A secure repository (today, almost always virtual) where the seller posts due-diligence documents for buyer review. Access is staged by deal phase and bidder identity.
- [Deal sourcing](https://mnapedia.com/wiki/deal-sourcing): The activity of identifying and engaging acquisition targets — through bankers, broker networks, proprietary outreach, conferences, screened lists and inbound referrals.
- [Definitive purchase agreement](https://mnapedia.com/wiki/purchase-agreement): The binding contract that governs an acquisition and its terms.
- [Due diligence](https://mnapedia.com/wiki/due-diligence): The structured investigation a buyer conducts on a target between LOI and closing — covering financial, legal, tax, commercial, operational, IT, HR and environmental workstreams — to verify the seller’s claims, find risks and shape final price and deal terms.
- [Exclusivity](https://mnapedia.com/wiki/exclusivity): A binding period (usually 30–90 days) within an LOI during which the seller agrees not to negotiate or accept competing offers, while the buyer completes diligence.
- [Fairness opinion](https://mnapedia.com/wiki/fairness-opinion): A formal written opinion from an investment bank that the consideration in a proposed deal is fair, from a financial point of view, to a specified group of shareholders.
- [Go-shop clause](https://mnapedia.com/wiki/go-shop-clause): An exception to a no-shop that allows the seller to actively solicit competing offers for a short window after signing — common in some PE-led public deals.
- [Indication of interest](https://mnapedia.com/wiki/indication-of-interest): A non-binding, written response from a buyer giving a preliminary valuation range, structure preferences and key conditions. Used to short-list bidders before LOIs.
- [Investment banking in M&A](https://mnapedia.com/wiki/investment-banking-in-ma): The advisory role banks play in originating, valuing and executing deals.
- [Letter of intent](https://mnapedia.com/wiki/letter-of-intent): A preliminary document outlining the main terms of a proposed deal, mostly non-binding.
- [M&A broker vs investment banker](https://mnapedia.com/wiki/broker-vs-banker): Business brokers and investment bankers both run sell-side processes, but differ on deal size, fee structure, buyer reach and depth of materials. Brokers dominate sub-$10M; bankers dominate $10M+.
- [Management presentation](https://mnapedia.com/wiki/management-presentation): A live or virtual meeting between short-listed bidders and the target's management team. Often the first interaction between buyer and the operating leaders.
- [No-shop clause](https://mnapedia.com/wiki/no-shop-clause): A provision in an LOI or definitive agreement that bars the seller from soliciting, encouraging or negotiating alternative offers during a defined window.
- [Non-disclosure agreement](https://mnapedia.com/wiki/nda): A confidentiality contract executed before a buyer receives the CIM. It binds the buyer to use the target's information only to evaluate the transaction.
- [Quality of earnings report](https://mnapedia.com/wiki/qofe-report): The formal deliverable from a quality-of-earnings engagement — a third-party accountant's analysis of a target's reported earnings, normalisation adjustments and revenue and cost trends.
- [Sell-side M&A process](https://mnapedia.com/wiki/sell-side-ma-process): The deal cycle from the seller's perspective: preparation, marketing materials, buyer outreach, IOIs, LOIs, exclusivity, due diligence, definitive agreement and closing.
- [Teaser](https://mnapedia.com/wiki/teaser): A one-to-two-page anonymous summary used by sell-side advisors to introduce a target to potential buyers without disclosing its identity until an NDA is signed.
- [Tender offer](https://mnapedia.com/wiki/tender-offer): A public offer made directly to shareholders to buy their shares, usually at a premium.

### Deal structures

How a transaction is legally and economically assembled — what is bought, and how it is paid for.

- [All-cash deal](https://mnapedia.com/wiki/all-cash-deal): A deal in which the consideration is paid entirely in cash. Eliminates buyer-stock risk for the seller, but is taxable to selling shareholders.
- [All-stock deal](https://mnapedia.com/wiki/all-stock-deal): A deal in which sellers receive only the buyer's shares as consideration. Can be tax-deferred for shareholders if structured as a qualifying reorganization.
- [Asset purchase](https://mnapedia.com/wiki/asset-purchase): A deal structure in which the buyer acquires specific assets (and assumes specific liabilities) of the target, rather than buying its equity. Generally favoured by buyers for liability and tax reasons.
- [Deal structure](https://mnapedia.com/wiki/deal-structure): How an acquisition is legally and economically assembled — chiefly the choice between an asset purchase and a stock purchase, and the tax, liability and consent consequences that flow from it.
- [Earnout](https://mnapedia.com/wiki/earnout): Deferred, contingent payments tied to the target’s post-close performance, used to bridge buyer–seller valuation gaps but a frequent source of post-closing dispute.
- [Escrow](https://mnapedia.com/wiki/escrow): A portion of the purchase price held by a neutral third party for a specified period after closing. Acts as a ready source of funds to satisfy the seller's indemnification obligations.
- [Forward triangular merger](https://mnapedia.com/wiki/forward-triangular-merger): A merger in which a wholly owned subsidiary of the buyer survives and the target merges into it. Often used for tax and liability isolation reasons.
- [Holdback](https://mnapedia.com/wiki/holdback): Purchase-price consideration that the buyer retains rather than pays out at closing, to be released later subject to conditions. Function is similar to an escrow but with the buyer (not a third party) holding the funds.
- [Indemnification](https://mnapedia.com/wiki/indemnification): The contractual mechanism by which the seller compensates the buyer (or vice versa) for losses resulting from breaches of representations, warranties or covenants in the definitive agreement.
- [Material adverse change clause](https://mnapedia.com/wiki/mac-clause): A provision allowing the buyer to walk from the deal between signing and closing if the target suffers a major, durationally significant adverse change. Heavily negotiated and rarely successfully invoked.
- [Mixed consideration](https://mnapedia.com/wiki/mixed-consideration): A deal that pays sellers with a combination of cash, stock, earnouts, seller notes and rollover equity — by far the most common shape of modern private deals.
- [Representations and warranties insurance](https://mnapedia.com/wiki/rwi-insurance): A policy that pays out for breaches of the seller's deal reps and warranties, replacing or supplementing the indemnification escrow. Now standard in most $20M+ private deals.
- [Reverse triangular merger](https://mnapedia.com/wiki/reverse-triangular-merger): A merger in which the target survives, having absorbed a subsidiary of the buyer. The most common public-company acquisition structure because it preserves target contracts.
- [Rollover equity](https://mnapedia.com/wiki/rollover-equity): Existing equity that the seller (often the founder or management team) retains in the post-close business rather than cashing out at closing. Standard in PE-backed deals to keep operators incentivised.
- [Statutory merger](https://mnapedia.com/wiki/statutory-merger): A combination governed by state corporate-law statute in which one constituent corporation absorbs the other, with the surviving entity inheriting all rights and obligations by operation of law.
- [Stock purchase](https://mnapedia.com/wiki/stock-purchase): A deal structure in which the buyer acquires the equity of the target entity, taking it whole — assets, liabilities, contracts and history. Generally favoured by sellers.
- [Working-capital target](https://mnapedia.com/wiki/working-capital-target): A negotiated benchmark — usually a trailing-12-month average — for the level of net working capital the seller is to deliver at closing. Variances above or below trigger a dollar-for-dollar price adjustment.

### Financing & buyouts

How deals are funded, including debt-financed acquisitions and private equity buyouts.

- [Dividend recapitalisation](https://mnapedia.com/wiki/dividend-recap): A specific form of leveraged recap in which the proceeds are paid out as a dividend to equity holders. Most common in private-equity portfolio companies seeking interim returns.
- [Entrepreneurship through acquisition](https://mnapedia.com/wiki/eta): The category of transactions in which an individual entrepreneur acquires an existing operating business — most commonly via a search fund, self-funded search or SBA-financed deal.
- [Leveraged buyout](https://mnapedia.com/wiki/leveraged-buyout): An acquisition financed largely with borrowed money, repaid from the target’s cash flows.
- [Leveraged recapitalisation](https://mnapedia.com/wiki/leveraged-recap): A transaction in which a company borrows substantial debt and uses the proceeds to repurchase shares or pay a special dividend, increasing leverage and (often) returning capital to owners.
- [Management buy-in](https://mnapedia.com/wiki/management-buy-in): An acquisition by an external management team that intends to take operating control of the target after closing. Distinct from an MBO in that the buyers are not the incumbents.
- [Management buyout](https://mnapedia.com/wiki/management-buyout): A transaction in which the existing management team acquires the company they run, typically with private-equity or debt financing. Common in PE secondaries and family-business succession.
- [Mezzanine debt](https://mnapedia.com/wiki/mezzanine-debt): Subordinated debt with equity features such as warrants or PIK interest. Sits between senior debt and equity in the capital structure, with correspondingly higher cost.
- [SBA acquisition financing](https://mnapedia.com/wiki/sba-acquisition-financing): U.S. Small Business Administration-guaranteed loans, particularly the SBA 7(a) program, used to finance acquisitions of small businesses up to roughly $5M in total project size.
- [Search fund](https://mnapedia.com/wiki/search-fund): An entrepreneurial vehicle in which one or two operators raise modest investor capital to search for, acquire and operate a single small or lower-mid-market company.
- [Seller financing](https://mnapedia.com/wiki/seller-financing): A note from the buyer to the seller for a portion of the purchase price, typically subordinated to senior debt. Common in lower-mid-market and main-street deals as a bridge between buyer cash and bank financing.
- [Unitranche](https://mnapedia.com/wiki/unitranche): A single debt instrument that combines senior and subordinated tranches in one document at a blended rate, increasingly used in mid-market LBOs in lieu of separate credit facilities.

### Takeovers & defenses

Unsolicited bids and the tactics targets use to resist or shape them.

- [Crown-jewel defense](https://mnapedia.com/wiki/crown-jewel-defense): A tactic in which the target sells, spins or grants an option on its most valuable assets to a friendly party, making the company less attractive to a hostile acquirer.
- [Dual-class shares](https://mnapedia.com/wiki/dual-class-shares): An equity structure with two or more share classes carrying different voting rights, typically used by founders to retain control of public companies (e.g., Google, Meta, Snap).
- [Golden parachute](https://mnapedia.com/wiki/golden-parachute): A contractual severance package — typically multi-year salary, accelerated equity vesting and benefits — paid to senior executives if they are terminated following a change of control.
- [Greenmail](https://mnapedia.com/wiki/greenmail): A target's repurchase of the hostile bidder's accumulated stake at a premium in exchange for a standstill agreement. Largely extinct in modern practice; subject to punitive U.S. tax.
- [Hostile takeover](https://mnapedia.com/wiki/hostile-takeover): An acquisition pursued against the wishes of the target company’s board.
- [Pac-Man defense](https://mnapedia.com/wiki/pac-man-defense): A defensive tactic in which the target turns around and attempts a hostile acquisition of the original bidder. Rare and aggressive; Bendix–Martin Marietta (1982) is the canonical example.
- [Poison pill](https://mnapedia.com/wiki/poison-pill): A defense that lets a target dilute a hostile bidder by issuing cheap shares to others.
- [Proxy fight](https://mnapedia.com/wiki/proxy-fight): A campaign by a hostile bidder or activist to win shareholder votes for board seats or transaction approval, usually as an alternative or complement to a tender offer.
- [Staggered board](https://mnapedia.com/wiki/staggered-board): A board structure in which only a fraction (commonly one-third) of directors stand for election each year. Slows hostile takeovers by preventing a single annual meeting from replacing the full board.
- [White knight](https://mnapedia.com/wiki/white-knight): A friendly third-party bidder that a target seeks out to outbid an unwelcome hostile acquirer, usually on terms more favourable to incumbent management or shareholders.

### Regulation & antitrust

Government review of mergers for competition and other public-interest concerns.

- [EU Merger Regulation](https://mnapedia.com/wiki/eu-merger-regulation): Council Regulation (EC) No 139/2004, which gives the European Commission jurisdiction over mergers with an EU dimension. Deals above turnover thresholds are reviewed at EU level rather than by member states.
- [FTC merger review](https://mnapedia.com/wiki/ftc-merger-review): Competition review of a transaction by the U.S. Federal Trade Commission, sharing jurisdiction with the DOJ Antitrust Division for HSR-reportable deals.
- [Hart-Scott-Rodino Act](https://mnapedia.com/wiki/hsr-act): The U.S. Hart-Scott-Rodino Antitrust Improvements Act of 1976, which requires premerger notification and an initial waiting period for transactions exceeding statutory size thresholds.
- [Herfindahl-Hirschman Index](https://mnapedia.com/wiki/hhi): A measure of market concentration calculated as the sum of squared market shares. Used by U.S. and EU antitrust authorities as the primary screening metric in merger reviews.
- [Market definition](https://mnapedia.com/wiki/market-definition): The threshold step in any antitrust merger analysis: identifying the relevant product and geographic market in which the parties compete, against which concentration is then measured.
- [Second Request](https://mnapedia.com/wiki/second-request): An extended antitrust investigation under HSR in which the reviewing agency demands additional information after the initial 30-day waiting period, lengthening review by months.

### Accounting

How acquisitions are recorded in the financial statements of the buyer.

- [ASC 805 — Business Combinations](https://mnapedia.com/wiki/asc-805): The U.S. GAAP standard governing accounting for business combinations. Largely converged with IFRS 3 since 2008.
- [Bargain purchase](https://mnapedia.com/wiki/bargain-purchase): An acquisition in which the fair value of net identifiable assets exceeds the consideration paid. The excess is recognised immediately in earnings rather than deferred as goodwill.
- [Contingent consideration](https://mnapedia.com/wiki/contingent-consideration): Purchase-price components whose payment depends on future events, such as earnouts. Initially measured at fair value at acquisition date, with subsequent changes generally hitting earnings.
- [Deferred tax in M&A](https://mnapedia.com/wiki/deferred-tax-in-ma): The deferred tax assets and liabilities recognised on differences between book and tax basis of assets and liabilities acquired in a business combination.
- [Goodwill](https://mnapedia.com/wiki/goodwill): The intangible asset recorded when a buyer pays more than the fair value of net assets.

- [Intangible assets in M&A](https://mnapedia.com/wiki/intangible-assets-in-ma): Identifiable non-physical assets — customer relationships, brands, technology, contracts — recognised separately from goodwill in purchase price allocation.
- [Measurement-period adjustments](https://mnapedia.com/wiki/measurement-period-adjustments): Adjustments to provisional acquisition-accounting amounts within a one-year window after acquisition, as new information about facts existing at acquisition date emerges.
- [Purchase price allocation](https://mnapedia.com/wiki/purchase-price-allocation): The process of assigning an acquisition’s price to the assets and liabilities acquired.

### Tax

Tax structures, elections and treatment of M&A transactions.

- [Basis step-up](https://mnapedia.com/wiki/basis-step-up): An increase in the tax basis of acquired assets to fair market value, allowing the buyer to depreciate or amortise the higher basis going forward. Available in asset deals and 338-elected stock deals.
- [F-reorganization](https://mnapedia.com/wiki/f-reorganization): A tax-free 'mere change in form' reorganization under Section 368(a)(1)(F), commonly used to restructure an S-corporation prior to a sale to enable a stock deal that gets asset-deal tax treatment.
- [NOL preservation (Section 382)](https://mnapedia.com/wiki/nol-preservation): U.S. Internal Revenue Code Section 382, which limits a corporation's ability to use pre-acquisition net operating losses after a more-than-50% ownership change.

- [Section 338(h)(10) election](https://mnapedia.com/wiki/338h10-election): A joint U.S. tax election that treats the stock acquisition of a domestic corporation (typically an S-corp or subsidiary) as a deemed asset purchase for tax purposes, giving the buyer a basis step-up.
- [Section 368 reorganization types](https://mnapedia.com/wiki/reorganization-types): The Section 368 categories of tax-free reorganizations — Type A (statutory merger), Type B (stock-for-stock), Type C (stock-for-asset), Type D (acquisitive D), Type F (form change) and others.
- [Tax due diligence](https://mnapedia.com/wiki/tax-due-diligence): The tax-focused workstream of buy-side diligence: federal/state/local income tax exposure, sales-and-use tax, payroll tax, transfer pricing, R&D credits, and the tax history of the target entity.
- [Taxable vs tax-free reorganization](https://mnapedia.com/wiki/taxable-vs-tax-free-reorganization): The threshold tax-structure question in U.S. M&A: whether the seller recognises gain at closing (taxable) or whether the transaction qualifies for non-recognition under the reorganization rules of Section 368.

### Integration

Post-merger integration: making the combined company work after closing.

- [Change management](https://mnapedia.com/wiki/change-management): The structured approach to transitioning people, teams and processes from a current state to a desired future state during integration — communications, training, role changes and adoption tracking.
- [Cultural integration](https://mnapedia.com/wiki/cultural-integration): The work of aligning the values, decision norms, communication patterns and incentives of the combining organisations. Often the slowest and most consequential PMI workstream.
- [Day 1 readiness](https://mnapedia.com/wiki/day-1-readiness): The set of activities that must be completed by the closing date so the combined company can transact business — payroll, communications, customer-facing systems, regulatory filings.
- [Day 100 plan](https://mnapedia.com/wiki/day-100-plan): A first-100-days roadmap defining the integration's most consequential decisions, milestones, owners and metrics for the period immediately following closing.
- [Integration Management Office](https://mnapedia.com/wiki/imo): A dedicated team — usually with executive sponsorship — that coordinates the integration across functional workstreams. Cycles of weekly cadence and clear governance are standard.
- [Integration playbook](https://mnapedia.com/wiki/integration-playbook): A standardised, often industry-tailored set of procedures, checklists and templates used by repeat acquirers to execute integrations consistently across deals.
- [IT integration](https://mnapedia.com/wiki/it-integration): The technical workstream of post-merger integration: networks, identity, ERP, CRM, data, security and end-user computing. Frequently the longest pole in the integration tent.
- [Post-merger integration](https://mnapedia.com/wiki/post-merger-integration): The combination of the two organisations' operations, systems, people and culture after closing. Most acquisitions that destroy value do so in PMI, not at the deal-pricing stage.
- [Retention bonuses](https://mnapedia.com/wiki/retention-bonuses): Cash or equity payments contingent on key employees remaining with the combined company for a defined period after closing. Standard for engineering, sales and finance leadership in mid-market deals.
- [Synergy realization](https://mnapedia.com/wiki/synergy-realization): The execution side of the synergies underwritten in the deal model: tracking and capturing planned cost reductions and revenue uplifts against schedule and dollar targets.

### Industry & specialty

M&A in specific industries and ownership contexts, from home services to family-owned businesses.

- [Cross-border M&A](https://mnapedia.com/wiki/cross-border-ma): Transactions in which buyer and target are in different jurisdictions. Layers on currency, foreign-investment review, multi-jurisdiction tax planning, employment law and cultural-integration complexity.
- [Distressed M&A](https://mnapedia.com/wiki/distressed-ma): M&A involving financially distressed or insolvent targets, often executed via Section 363 sales, Chapter 11 restructurings or out-of-court workouts. Speed, certainty and free-and-clear title dominate the value drivers.
- [Family-business M&A](https://mnapedia.com/wiki/family-business-ma): Acquisitions of family-owned and -operated companies. Distinctive features include succession planning, owner-dependence concerns, normalisation of personal expenses and earnouts tied to founder transition.
- [Founder-led transitions](https://mnapedia.com/wiki/founder-led-transitions): M&A that doubles as the operating handoff from a founder-owner to professional management or a buyer's team. Common in SBA and lower-mid-market deals; key-person risk is the central diligence theme.
- [Healthcare M&A](https://mnapedia.com/wiki/healthcare-ma): M&A in healthcare and life sciences. Heavily shaped by reimbursement, clinical-trial value, regulatory approvals, FDA / ANDA portfolios, and licensing structures distinct from generic deal practice.
- [Home-services M&A](https://mnapedia.com/wiki/home-services-ma): Mergers and acquisitions in the home-services industry — HVAC, plumbing, electrical, roofing, pest control, landscaping, garage doors and adjacent verticals. A roll-up-heavy, PE-backed segment of the lower-middle market.
- [SaaS M&A](https://mnapedia.com/wiki/saas-ma): Mergers and acquisitions in software-as-a-service businesses. Distinctive features include ARR-based valuation, retention metrics, deferred revenue treatment in PPA, and tech / IP diligence.

### Advisors & roles

The professionals who originate, value, structure and close M&A transactions.

- [Fairness opinion provider](https://mnapedia.com/wiki/fairness-opinion-provider): An investment bank or specialty firm that issues a written opinion that the consideration in a proposed transaction is fair to a specified group of shareholders, from a financial point of view.
- [M&A accountant](https://mnapedia.com/wiki/ma-accountant): CPA or transaction-services accountant who runs quality-of-earnings analysis, working-capital benchmarking, tax structuring and post-close purchase-price allocation work.
- [M&A advisor / business broker](https://mnapedia.com/wiki/ma-advisor-business-broker): Sell-side advisor focused on the lower-middle market and main-street segment, typically for deal sizes from sub-$1M up to ~$25M. Distinct from investment bankers in scale, fee structure and process style.
- [M&A lawyer](https://mnapedia.com/wiki/ma-lawyer): Transactional attorney specialising in mergers and acquisitions: drafts and negotiates the LOI, definitive agreement and ancillary documents, and runs the closing mechanics.
- [Transaction advisor](https://mnapedia.com/wiki/transaction-advisor): Big-Four (or similar) transaction-advisory practitioner who delivers buy-side or sell-side QoE, financial diligence, tax structuring and integration-readiness work, separate from audit.
