EBITDA Growth Rate
EBITDA growth rate measures the percentage change in a company's earnings before interest, taxes, depreciation, and amortisation over a period; unlike revenue growth, it captures operational efficiency improvements alongside volume expansion, and acceleration in EBITDA growth relative to revenue growth signals margin expansion.
EBITDA growth rate is computed analogously to revenue CAGR but using EBITDA figures. Its significance lies in stripping out the noise of capital structure (interest), tax jurisdiction (taxes), and accounting policies for long-lived assets (depreciation and amortisation), leaving a measure that reflects the core operational earning power of the business. When a company grows revenues at 15% but EBITDA at 25%, it is demonstrating operating leverage — fixed costs are being absorbed across a larger revenue base, improving margins.
Operating leverage is the key mechanism by which EBITDA growth can outpace revenue growth. Companies with high fixed-cost structures — telecom networks, airlines, theme parks, capital-intensive manufacturing — show amplified EBITDA growth when revenues rise because incremental revenue flows largely to the bottom line after fixed costs are covered. The converse is equally true: in a downturn, EBITDA contracts faster than revenue for high-operating-leverage businesses, a fact that caught many investors off guard during the COVID-19 disruption.
In Indian equity research, EBITDA growth trajectory is often plotted against EBITDA margin evolution to distinguish between two types of growth stories. The first is margin expansion driven growth — a business earning higher EBITDA not because it is selling more but because it has improved its cost structure, pricing power, or product mix. The second is volume-led growth with stable margins, which is more replicable but potentially more competitive. The most compelling growth stories combine both: rising volumes and improving margins simultaneously.
Sectors like specialty chemicals, pharmaceuticals, and API manufacturers in India have seen EBITDA CAGRs of 20–30% over extended periods, driven by both import substitution tailwinds boosting volumes and improved product mix shifting toward higher-margin formulations or custom synthesis. Conversely, commodity chemicals and basic steel producers have shown volatile EBITDA profiles that track raw material and product price cycles rather than structural business improvement.
Analysts should be alert to EBITDA manipulation through changes in accounting policies — for example, a shift from expensing employee stock option costs (ESOP) to burying them in notes, or reclassifying certain recurring costs as exceptional items. These practices artificially inflate reported EBITDA while leaving the underlying economics unchanged. Comparing reported EBITDA to operating cash flow over time helps identify whether EBITDA growth is translating into actual cash generation.
