Runa Capital II (GP) (“Runa”)

Statement regarding possible offer for MariaDB plc (“MariaDB” or “the Company”)

Dublin, Ireland, Sept. 15, 2023 (GLOBE NEWSWIRE) -- Runa announces that it made, on 14 September 2023, an all cash proposal to the Board of MariaDB (the “Board”) to acquire, together with Runa’s investment affiliates, 100% of the issued share capital of the Company not already owned by Runa, at a price of US$0.56 per share (the “Possible Offer”).

As of 14 September 2023 (being the last business day before the date of this announcement), Runa and its investment affiliates owned 5,269,012 ordinary shares of the Company, representing approximately 7.8 per cent. of the Company’s issued ordinary share capital as at such date.

The terms of the Possible Offer represent a premium of approximately 24% to the closing price of MariaDB shares on 13 September 2023 of US$0.45 per share (being the last business day before the date of the Possible Offer proposal).

Given the substantial and consistent losses the Company has incurred and its subscale level of revenue⁽¹⁾, Runa believes that the Company is highly challenged as a public company. The Company has expressed substantial doubt about its ability to continue as a going concern⁽²⁾ and Runa believes that the Company will continue to face severe challenges as a public company. Runa believes that the terms of its possible offer would deliver significant value for the Company’s shareholders. As an interim measure, Runa is prepared to extend to the Company a $5 million bridge loan on terms to be agreed between the parties such that the Company can avert impending default under its senior debt⁽³⁾.

It is intended that the proposed transaction would be effected by way of an Irish law scheme of arrangement whereby Runa would acquire 100% of the issued shares of the Company other than those shares already owned by Runa. However, Runa reserves the right to implement the proposal, instead, by way of contractual offer.

There can be no certainty that any offer will be made, nor as to the terms on which any such offer might be made.

In accordance with Rule 2.6(a) of the Irish Takeover Rules, Runa must, by no later than 5.00 p.m. on 27 October 2023 either announce a firm intention to make an offer for the Company in accordance with Rule 2.7 of the Irish Takeover Rules or announce that it does not intend to make an offer, in which case the announcement will be treated as a statement to which Rule 2.8 of the Irish Takeover Rules applies. This deadline may be extended with the consent of the Panel in accordance with Rule 2.6(c) of the Irish Takeover Rules.

Pursuant to Rule 2.5 of the Irish Takeover Rules, Runa reserves the right to vary the form and / or mix of the offer consideration and vary the transaction structure. Runa also reserves the right to amend the terms of any offer (including making the offer on less favourable terms or at a lower price than US$0.56 per share):

(a) with the recommendation or consent of the Board;

(b) if MariaDB announces, declares or pays any dividend or any other distribution or return of value to its shareholders after the date of this announcement, in which case Runa reserves the right to make an equivalent adjustment to its proposed offer;

(c) following the announcement by MariaDB of a whitewash transaction pursuant to the Irish Takeover Rules; or

(d) if a third party announces a firm intention to make an offer for MariaDB on less favourable terms or at a lower price than US$0.56 per share.

A further announcement will be made as and when appropriate.

Disclosure Requirements under the Irish Takeover Rules

Under Rule 8.3(a) of the Irish Takeover Rules, any person who is ‘interested’ in 1% or more of any class of ‘relevant securities’ of the Company or a securities exchange offeror (being any offeror other than an offeror which has announced that its offer is, or is likely to be, solely in cash) must make an ‘opening position disclosure’ following the commencement of the ‘offer period’ and, if later, following the announcement in which any securities exchange offeror is first identified. An ‘opening position disclosure’ must contain, among other things, details of the person’s ‘interests’ and ‘short positions’ in any ‘relevant securities’ of each of (i) the Company and (ii) any securities exchange offeror(s). An ‘opening position disclosure’ by a person to whom Rule 8.3(a) applies must be made by no later than 3:30 pm (Irish time) on the day that is ten ‘business days’ following the commencement of the ‘offer period’ and, if appropriate, by no later than 3:30 pm (Irish time) on the day that is ten ‘business days’ following the announcement in which any securities exchange offeror is first identified.

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 the Company, all ‘dealings’ in any ‘relevant securities’ of the Company 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 (Irish 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 the Company, they will be deemed to be a single person for the purpose of Rule 8.3 of the Irish Takeover Rules. A disclosure table, giving details of the companies in whose ‘relevant securities’ ‘dealings’ should be disclosed can be found on the Irish Takeover Panel’s website at www.irishtakeoverpanel.ie.

If two or more persons co-operate on the basis of an agreement or understanding, whether express or tacit, either oral or written, to acquire or control an interest in relevant securities of an offeree company or a securities exchange offeror, they will be deemed to be a single person for the purpose of Rule 8.3 of the Irish Takeover Rules.

Opening Position Disclosures must also be made by the offeree company and by any offeror and Dealing Disclosures must also be made by the offeree company, by any offeror and by any persons acting in concert with any of them (see Rules 8.1 and 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.

Details of the offeree and offeror companies in respect of whose relevant securities Opening Position Disclosures and Dealing Disclosures must be made can be found in the Disclosure Table on the Takeover Panel’s website at www.irishtakeoverpanel.ie, including details of the number of relevant securities in issue, when the offer period commenced and when any offeror was first identified. If you are in any doubt as to whether or not you are required to disclose a ‘dealing’ under Rule 8, please consult the Irish Takeover Panel’s website at www.irishtakeoverpanel.ie or contact the Irish Takeover Panel at telephone number +353 1 678 9020.
