It then buys smaller companies, the add-ons, and combines them with the platform. The platform is the fund's investment, with its own entry price and holding period; the add-ons are normally bought by the platform itself.","parent_concepts":["buy-and-build"],"child_concepts":[],"related_concepts":["add-on-acquisition","leveraged-buyout","portfolio-company","delayed-draw-term-loan","track-record","adjusted-ebitda","value-bridge"],"comparison_concepts":[],"not_the_same_as":[{"slug":"add-on-acquisition","distinction":"An add-on is a later acquisition made by the platform; the platform is the fund's original investment."},{"slug":"buy-and-build","distinction":"Buy-and-build is the strategy; the platform is the first transaction in it."},{"slug":"portfolio-company","distinction":"Every platform is a portfolio company, but not every portfolio company is meant to make acquisitions."}],"formula_ids":[],"worked_examples":[],"sections":[{"heading":"What makes a company a platform","paragraphs":["A platform is defined by its role in the plan, not by its size. In practice, sponsors look for a management team able to run a larger, integrating business; finance and reporting systems that can consolidate acquisitions quickly (monthly close, key performance indicator (KPI) reporting, controls); operations that scale; a market with enough acquirable targets; and debt capacity, with a credit agreement that permits acquisitions through incremental or [delayed-draw term loan](/glossary/delayed-draw-term-loan) facilities. In a [buy-and-build](/glossary/buy-and-build) strategy everything later rests on the choice of platform: if the platform cannot integrate, every later [add-on acquisition](/glossary/add-on-acquisition) adds risk rather than value."]},{"heading":"How platforms are financed","paragraphs":["The platform is normally acquired in a [leveraged buyout](/glossary/leveraged-buyout). The financing package is often sized with acquisitions in mind: an acquisition or incremental facility, permission to add debt up to a leverage test, and baskets for seller notes and earn-outs. Add-ons are then funded with that debt capacity, the platform's own cash, deferred consideration to sellers, sellers rolling equity into the platform, or new equity from the fund and co-investors. Each funding choice changes leverage and the fund's cost basis in the same company."]},{"heading":"Platforms in fund reporting and track records","paragraphs":["For fund reporting, a platform and its add-ons are usually one portfolio company: equity injected to fund add-ons increases the cost of the original investment rather than creating a new holding. That convention is reasonable, but it means one line in a track record can contain many acquisitions bought at different prices. LPs reviewing a [track record](/glossary/track-record) ask for the equity invested at entry and afterwards, EBITDA bought through acquisitions versus grown organically, and the multiples paid for add-ons compared with the platform's entry and exit multiples."]},{"heading":"Platform selection risk","paragraphs":["Common failure modes are a management team stretched by the pace of acquisitions, systems that never consolidate (so lenders and buyers cannot rely on reported figures), customer or staff losses during integration, and a financing structure whose leverage rises with each debt-funded add-on. A sponsor that cannot show its platform selection criteria, deals it rejected and its integration record is asking LPs to underwrite the acquisition plan on trust."]}],"classification_rules":["Classify an acquisition as a platform investment when the sponsor's plan at entry includes further acquisitions to be made through the company.","Classify later acquisitions made by that company as add-ons, not new platforms, even when they are funded with new fund equity.","If no acquisition programme is planned or executed, classify the deal as a buyout of a stand-alone portfolio company."],"calculation_rules":[],"common_mistakes":["Equating \"platform\" with \"large deal\".
