Not a silly question at all. This is an all-too-frequently misunderstood topic on LSE boards. There are a variety of profit measures, some of which are confusingly named or duplicative. I will try to summarise them...
GROSS PROFIT: This is the difference between a firm's total revenue and the cost of the goods sold over a given period. For a company like ODX, the cost of goods (COGS) includes the cost of LFT cassettes, test strips, reagents etc. But it excludes many other expenses related to running the business - such as rent, salary costs, marketing expenses and other business overheads. It is sometimes calculated as a percentage and called Gross Margin. It’s useful when you are looking at the economics of a business, but only part of what you need if you are attempting to value a company.
OPERATING PROFIT: Operating Profit is calculated in the same way as Gross Profit, except it factors in ALL of the operating costs, including the examples above. It is sometimes referred to as EBIT - earnings before interest and taxes. If quoted before the inclusion of so-called “non-cash” expenses it is frequently presented as EBITDA - earnings before interest, taxes, depreciation and amortisation. This is liked by analysts as it is an approximation of cashflow (& cashflow is the basis for NPV valuations) and by company management as it allows them to hide stuff....
PBT or PRE-TAX PROFITt: This measure takes into account all of the above plus a business's interest costs on any debt financing it employs.
If you then deduct how much tax is due for the specified period, you get to another profit measure – PAT or profit after tax.
This is also known interchangeably as NET PROFIT, NET INCOME or EARNINGS. It is the number that is used to work out a company's all-important Earnings Per Share (EPS) figure. (Profit after tax divided by the number of shares a firm has in issue).
I hope that is clear. Sorry I couldn’t make it any easier to read and understand. I tried my best...!
