Scalability Premium

The ability of a business to grow revenue significantly without a proportional increase in costs or resources. Highly scalable businesses—often those built on software, platforms, or strong intangible assets—can expand margin as they grow, making them attractive to investors.

An adjustment applied to the standard WACC to reflect the additional risk associated with specific intangible assets or early-stage businesses. Intangible-heavy investments typically warrant a higher discount rate than the firm-level WACC because their cash flows are less certain and more sensitive to competitive and technological disruption.

The additional amount a buyer pays above the pro-rata market value of a company's shares to acquire a controlling interest. The control premium reflects the value of being able to direct the company's strategy, operations, capital allocation, and management.

The incremental return that investors require for holding equities over risk-free government bonds, reflecting the additional risk associated with equity ownership. The ERP is a critical input to cost of equity estimation under both CAPM and build-up methods.

An additional return demanded by investors for holding the equity of smaller companies, reflecting the empirically observed tendency for small-capitalisation stocks to earn higher returns than predicted by the Capital Asset Pricing Model alone. Size premiums are commonly sourced from the Duff & Phelps (now Kroll) Cost of Capital Navigator and are added to the cost of equity in the build-up method or as a modification to CAPM.

An additional return added to the cost of equity to reflect idiosyncratic risks unique to the subject company that are not captured by beta, the equity risk premium, or the size premium. Common factors justifying a specific company risk premium include customer concentration, key person dependence, regulatory exposure, limited product diversification, geographic concentration, and early-stage business risk.

An economic model built around digital platforms that create value by facilitating exchanges between two or more user groups. Platform businesses derive the majority of their enterprise value from intangible assets including network effects, proprietary algorithms, user data, and brand trust.

A sustainable competitive advantage that protects a business from rivals and preserves its market position over time. Moats are typically built from intangible assets: brand strength, network effects, switching costs, proprietary technology, or regulatory advantages.
