English term (edited): providing the Company’s interest

there must be a better formulation, but CL5 about the meaning.

"Receiving bribes, money or other personal interest from partners, or providing the Company’s interest to business partners is prohibited.\"

the clue as to the meaning of "interest" IN THIS ST is in:

Receiving bribes, money or other personal interest from partners
=
"other personal interest" is anything else than money that belongs to in some way to partners (like giving free holidays on their private island as a form of bribe, for example)

so by analogy the Company’s interest is anything that "belongs to" in some way to the Company (like letting some other business using for peanuts offices rented by the "briber", or in a less obfuscated form giving free shares in a subsidiary, or giving free stay in hotels belonging to the company etc etc)

it's the same meaning of "interest" as in "l'entreprise A a des intérêts dans ..."

Origin
late Middle English (originally as interess ): from Anglo-Norman French interesse, from Latin interesse ‘differ, be important’, from inter- ‘between’ + esse ‘be’. The -t was added partly by association with Old French interest ‘damage, loss’, apparently from Latin interest ‘it is important’. The original sense was ‘the possession of a share in or a right to something’; hence sense 4 of the noun. Sense 1 of the noun and the verb arose in the 18th century Sense 2 of the noun was influenced by medieval Latin interesse ‘compensation for a debtor's defaulting’.

when looking for the meaning of "interests" in this ST you have to keep a minimum of logical consistency:

the whole ST is about bribes [not about cartels, nor collusion, nor industrial espionage, nor ...]

Bribery is the act of giving money, goods or other forms of recompense to a recipient in exchange for an alteration of their behaviour (to the benefit/interest of the giver) that the recipient would otherwise not alter.

Bribery is defined by Black's Law Dictionary as the offering, giving, receiving, or soliciting of any item of value to influence the actions of an official or other person in charge of a public or legal duty.[1]

Gifts of money or other items of value which are otherwise available to everyone on an equivalent basis, and not for dishonest purposes, is not bribery. Offering a discount or a refund to all purchasers is a legal rebate and is not bribery. For example, it is legal for an employee of a Public Utilities Commission involved in electric rate regulation to accept a rebate on electric service that reduces their cost for electricity, when the rebate is available to other residential electric customers. If the rebate was done to influence them to look favorably on the electric utility's rate increase applications, however, that would be bribery, and unlawful.

The bribe is the gift bestowed to influence the recipient's conduct. It may be
money,
goods,
rights in action,
property,
preferment,
privilege,
emolument,
objects of value,
advantage, or
merely a promise to induce or influence the action, vote, or influence of a person in an official or public capacity.[2]
