Executive Summary

Situation Overview and Background Lazard’s client is K1 Investment Management, LLC (“K1”), a US-based investment firm primarily focused on the technology sector with AUM of ~$15 billion Lazard has been engaged by K1 on its take-private of MariaDB plc (“MariaDB” or “the Company”, NYSE: MRDB), a US-listed company domiciled in the US and Ireland (which therefore falls under the remit of the Irish Takeover Rules). The recommended cash offer has been made by Meridian BidCo LLC ("Bidco"), a newly formed affiliate of K1, as manager of K5 Private Investors, L.P. ("K5") MariaDB provides database software solutions and managed services for Enterprise and SMB customers The Company went public via SPAC (Angel Pond Holdings Corporation) in December 2022, but has struggled in the public market since then. As of February 15th, 2024, immediately prior to K1 announcing a R2.4 possible offer, MariaDB traded at ~$0.35 per share (vs. SPAC price of $10 / share) On April 24th, 2024, K1 released a R2.7 Announcement (the “R2.7 Announcement”) to acquire MariaDB. K1’s offer to acquire to MariaDB is as follows: $0.55 / share in cash for existing MariaDB shareholders (the “Cash Offer”), valuing the equity of MariaDB at ~$39.9 million; or As an alternative, shareholders may elect to reinvest into Meridian TopCo LLC (“TopCo”) (the “Unlisted Unit Alternative”) At the time of the R2.7 Announcement, K1 had received irrevocable undertakings to vote in favour of the offer / tender in to it in respect of 51.5% of the shareholder register As part of the Offer Document, an “appropriate financial advisor” is required under R24.11 of the Irish Takeover Rules to provide an estimate of the value of the Unlisted Unit Alternative. The purpose of this paper is to assess the value the Unlisted Unit Alternative The fully diluted share count of TopCo is ~265m shares per K1, representing an implied TopCo equity value of ~$145.7 million at a $0.55 issue price per share in TopCo The fully diluted share count of TopCo and Implied TopCo equity value is higher than those of MariaDB owing to a series of adjustments by K1 to reflect their entry price including, amongst other things, primary cash injection and the purchase of the company debt at a premium following a bilateral negotiation with the debt holder The Unlisted Unit Alternative allows current shareholders in MariaDB to reinvest in TopCo up to a total of 15% of the fully diluted equity value of TopCo In the event the Unlisted Unit Alternative is oversubscribed, reinvesting shareholders will be given a pro-rata entitlement and any surplus will be settled in cash at $0.55 / share In the event the Unlisted Unit Alternative is undersubscribed, those shareholders electing to reinvest will be able to acquire additional shares in TopCo at a price of $0.55 / share Source: K1 Management, Offer Document, R2.7 Announcement Executive Summary 4

Valuation Overview In appraising the valuation of TopCo we have utilised the following information: K1 “Base Case” Model – comprising estimates for the years FY24E-FY29E for TopCo We have not been provided with up to date forecasts prepared by management of MariaDB and, at the direction of K1, have utilized solely the K1 Operating Model for the purposes of our analysis Additional Information from K1 Management – EV to equity bridge items per Appendix - (“TopCo Net Cash Bridge”), Tax Rate, Terminal Year Forecast, Depreciation Assumptions Public Data Sources – FactSet, Mergermarket, Public Filings and the relevant sources for calculating WACC per slide 21 & 22 TopCo Capital Structure – K1 provided the fully diluted share count of TopCo and $ / share of the Unlisted Unit Alternative We have inferred a valuation (as at the latest practicable date being 16th May, 2024) based on the following methodologies: Comparable publicly traded companies – given the unique financial profile of MariaDB we derive a valuation range based on “Financially Relevant Peers” – software companies exhibiting low revenue growth and low EBITDA margins, similar to MariaDB’s current and near term forecast financial profile We have considered “Operationally Relevant Peers” in the calculation of CAPM WACC as they are most comparable to the characteristics of TopCo based on the forecasts outlined in the K1 Operating Model – however they do not directly inform the valuation range on a multiples basis (as is the case for the aforementioned Financially Relevant Peers) We have considered, but not included for our valuation purposes, “Reference Financial Peers” – companies demonstrating MariaDB’s future targeted financial profile in the event the K1 Operating Model is successfully executed For the purposes of our comparable publicly traded companies we consider revenue multiples and gross profit multiples alone in light of the significant operational turnaround and related uncertainties surrounding the path to delivering EBITDA improvement in the K1 Operating Model and steady state profitability Discounted cash flow analysis is utilised in our analysis based on the K1 Operating Model from FY24E onwards with appropriate sensitisation of WACC and TGR to derive our DCF implied valuation range We have assessed a WACC range using the CAPM method to inform our valuation analysis. For reference only, we have also calculated a DCF using the target returns of a representative US-based technology focused investment firm Executive Summary 5

Valuation Overview –Continued Based on the analysis above, we estimate a valuation for the Unlisted Unit Alternative in the range of $0.40 - $0.65 per share solely for the purposes of the Rule 24.11 letter This value range does not include any illiquidity or non-transferability discount, or any discount associated with the governance rights attached to the Unlisted Unit Alternative or the other factors set out in our 24.11 letter Attached to this document is a copy of the disclosure contained within the Offer Document summarising the Lazard valuation opinion and the Rule 24.11 letter, which should be read in conjunction with this document This document and our 24.11 letter has been provided to the directors of TopCo solely for the purposes of Rule 24.11 of the Irish Takeover Rules and may not be used or relied upon for any other purpose whatsoever Executive Summary 6

Low Case of 5.5% refers to Kroll “recommended” equity risk premium (as at 28-Feb-24) K1 plans to equitise the debt they currently own on closing, therefore the cost of debt for TopCo is n.a. and the target capital structure is 100% equity; 0% Debt Represents spot rate (as at 16-May-24) for 10-Year government bond yields weighted by FY23A revenue exposure USA corporate income tax rate A Operationally relevant peers have been considered in the calculation of WACC as they are more comparable to the characteristics of TopCo based on the forecasts outlined in the K1 Operating Model A D B Unlevered betas are sensitised from the 25th percentile of operationally relevant peers (low case) through to the 75th percentile (high case); with the central case taking the median of the peers. K1 plans to equitise the debt they currently own in MariaDB and therefore the levering factor is 1.0 (meaning levered beta is equivalent to unlevered beta) C D Equity market risk premia (ERP) are taken from Kroll Valuation Handbook. The lower value, is the Kroll “recommended” ERP (5.5%) – used in the low sensitivity case. The higher value is the Kroll “Historical long-term” ERP (7.2%) – used in both the high and central sensitivity cases B C Operationally Relevant Peers Appendix A country weighted risk-free rate is calculated using the spot rate on the 10-year government bonds for each of the top-15 countries by revenue share for MariaDB in FY23A (please see page 22 for further detail) 21
