Profit generated by a company's operations before interest payments and tax is called operating profit.
Operating profit is closely related to EBIT, and is usually the same.
There may be a difference between EBIT and operating profit. It is almost always small. It comes from the exclusion from operating profit of certain profits or losses that are not part of the operations of a business — such as profits on the sale of businesses.
Operating profit is an important measure because it tells you how much money a company (or a division: it is often disclosed at that level as well) makes from the actual operations of its business, without the effects of financing or tax.
Operating profit is subject to some distortions, hence the use of measures such as adjusted operating profit and EBITA.
