MOTA-ENGIL INFORMS ABOUT LIQUIDITY AGREEMENT

MOTA-ENGIL S.G.P.S., S.A. ("MOTA-ENGIL") informs that on March 27, 2023, has entered into a liquidity agreement ("Liquidity Agreement") with CAIXA – Banco de Investimento, S.A. ("CaixaBI"), aiming at promoting the liquidity of MOTA-ENGIL'S shares admitted to trading on the Euronext Lisbon regulated market.

The Liquidity Agreement will have a one-year term, entering into force at April 11, 2023, being automatically renewed for further equal periods, if neither party terminates it in writing and with, at least, 15 days prior notice before the successive extensions.

The transactions will be limited to a maximum position corresponding to an amount of MOTA-ENGIL'S shares equal to or greater than €200,000.00 (two hundred thousand Euros); to a net portfolio position in an amount equal to or greater than €50,000.00 (fifty thousand Euros); or to a traded amount, at each moment, of 30% of the volume traded on Euronext, defined in terms of quantity of shares.

The Liquidity Agreement shall be suspended, namely, in the following situations: (i) if the underlying asset is nonnegotiable; (ii) if the aggregate position, in terms of number of shares or investment made, reaches the agreed maximum position, as defined in the Liquidity Agreement; (iii) if a failure occurs in CaixaBI's trading systems; (iv) if any disclosure of a relevant fact leads to an abnormal variation in the price of the shares; (v) if there is any breach, by one of the parties, of its contractual obligations, notwithstanding the possibility of termination of the Liquidity Agreement by the compliant party; (vi) if there is a malfunction in the trading platform; (vii) if, in accordance with CaixaBI's criteria acting reasonably, there are any other events that may lead to significant changes in the market or to the volatility of the price of the shares.

The Liquidity Agreement shall be immediately and automatically terminated if according to CaixaBI's judgement, there is an objective conflict between the rights and obligations arising from the Liquidity Agreement and the law, or any applicable regulation, public practice, or orientation made public by any governmental, financial or tax authority and in case CaixaBI is suspended as an authorized market member.

MOTA-ENGIL may also terminate the Liquidity Agreement at any time, without just cause, by sending a written communication to CaixaBI, with a 30-day prior notice before the date decided that the termination of the Liquidity Agreement comes into force.
