Lisbon, 27 April 2023

Novabase - Sociedade Gestora de Participações Sociais, SA ("Novabase" or "Company") informs that its Board of Directors resolved to terminate the share buyback programme of the Company (the "Buy-back Programme") launched on 29 September 2021 and that meanwhile has been suspended following the publication by the Company on 16 February 2023 of the preliminary announcement for a public tender offer over treasury shares.

The objective of the Buy-Back Programme was the acquisition of the shares required to settle the options granted under the Company's Stock Option Plan in force.

As of 16 February 2023, Novabase had acquired a total of 277,773 own shares and had 1,787,434 additional treasury shares, holding a total of 6.58% of the current share capital of the company. As such, the estimated number of shares required to settle the options granted under the Company's Stock Option Plan has already been reached.

Therefore, Novabase informs that the purpose of such programme has been fulfilled and, accordingly, the Buy-Back Programme shall be deemed as concluded on the date hereof, terminating before its maximum duration deadline (31 December 2023).

The acquisitions of shares representing Novabase share capital under the Buy-Back Programme have been communicated on a regular basis, under the terms and for the

purposes of the applicable law, notably Commission Delegated Regulation (EU) 2016/1052 of 8 March 2016.

[It is further informed that, following the conclusion of the tender offer for treasury shares made by the company and in light of the new shareholder structure, the Board of Directors has decided to terminate the liquidity agreement between the Company and Caixa – Banco de Investimento, S.A. – that, as previously communicated to the market, was suspended during the execution of the Buy-Back Programme
