Depreciation and amortization (D&A) are not cash expenses, but accounting adjustments that reflect how assets lose value over time. Knowing this figure serves various purposes:

📌 1. Analyze actual operating profitability

EBITDA shows the 'ability to generate cash' without considering depreciation and amortization.

EBIT does include these expenses, providing a closer view of operating profit.

Example: A company with expensive machinery will have high depreciation. EBITDA will say 'it looks very profitable', but EBIT will show that profitability decreases once those costs are recognized.

📌 2. Compare companies with each other

Two companies with different assets (one machinery-intensive, the other software-intensive) can have similar EBITDA, but EBIT will differ due to depreciation.

D&A helps to see how 'heavy' a company's asset structure is.

📌 3. Company Valuation

Investors use EBITDA to see operating cash flow before non-cash expenses.

D&A is key to calculating metrics like EV/EBITDA or EV/EBIT in valuations.

📌 4. Financial Planning

A company needs to know how much its machinery depreciates or how much it amortizes its patents to plan future investments (CAPEX).

👉 In summary:

Knowing the D&A figure helps understand the difference between accounting profit and actual cash flow, in addition to measuring the 'burden' of the company's assets.
