Disclosure requirements of the Irish Takeover Rules

Under Rule 8.3(b) of the Irish Takeover Rules, if any person is, or becomes, 'interested' (directly or indirectly) in 1% or more of any class of 'relevant securities' of MariaDB, all 'dealings' in any 'relevant securities' of MariaDB or any securities exchange offeror (including by means of an option in respect of, or a derivative referenced to, any such 'relevant securities') must be publicly disclosed by not later than 3:30 pm (U.S. Eastern Time) on the 'business day' following the date of the relevant transaction. This requirement will continue until the 'offer period' ends. If two or more persons cooperate on the basis of any agreement either express or tacit, either oral or written, to acquire an 'interest' in 'relevant securities' of MariaDB, they will be deemed to be a single person for the purpose of Rule 8.3 of the Irish Takeover Rules.

Dealing Disclosures must also be made by any offeror and by any persons acting in concert with them in accordance with Rule 8.2 of the Irish Takeover Rules.

In general, interests in securities arise when a person has long economic exposure, whether conditional or absolute, to changes in the price of the securities. In particular, a person will be treated as having an 'interest' by virtue of the ownership or control of securities, or by virtue of any option in respect of, or derivative referenced to, securities. Terms in quotation marks are defined in the Irish Takeover Rules, which can be found on the Irish Takeover Panel's website.
