SUSTAINABLE AND SUSTAINED VALUE CREATION

With the aim of working every day to create sustainable and sustained value, Martifer Group is focused on its commitment to improving productivity, strengthening resilience, performance and well-being, today and in the long-term.

GENDER 5 EQUALITY	AFFORDABLE AND CLEAN ENERGY	8 ECONOMIC GROWTH ECONOMIC GROWTH	ANDINFRASTRUCTUR
REDUCED INEQUALITIES > A	RESPONSIBLE CONSUMPTION AND PRODUCTION	13 CLIMATE

Based on the SDGs we have prioritised, we want to:

• Work for an environmentally positive world and be resource efficient

• Create fair and equal opportunities

• Live according to the values we have defined

IN 2023	CARBON NEUTRALITY Positive or neutral balance in emissions: Considering the energy mix that the Group has, Martifer can today affirm that it is neutral in terms of emissions.		Promote a balance between personal/ professional life and diversity, equity and inclusion.	ENERGY CONSUMPTION 6% less energy consumption in toe's per million € invoiced, which is equivalent to 6% less CO2 emissions per million € invoiced compared to 2022.		Production Units for Self consumption Collective self consumption, with 30% of consumption from renewable energy.
DEVELOPMENT WASTE PRODUCTION Investing in our people: 25% more training hours compared to 2022. million € invoiced. More than 90% of waste sent for recovery, for the 11th (a target set by the Group).		20% less waste produced in tonnes per consecutive year	SAFETY 11% less frequency of accidents at work compared to 2022.	Integrate sustainability into the Group's culture and reinforce its presence on a daily basis.	CONSUMPTION Implementation of the Smart Factory project, cutting down on resources.

In 2024, an update to the strategic plan will be drawn up, based on the pillars that have underpinned the success of recent years, but with the reinforced ambition of sustained and sustainable growth:

• In Metallic Constructions, the focus remains on strengthening the Group's export profile, seeking opportunities in markets and clients that value quality and excellence, on organisation and valuing people, and on productivity;
• In Naval Industry, we plan to increase our ship repair capacity by building a new dry dock at the Viana do Castelo shipyard, positioning ourselves as one of the most important shipyards in Europe in this area and making ship repair and shipbuilding activities increasingly balanced in terms of relative weight in turnover;
• Reinforce the activity of Operation & Maintenance, particularly Industrial Maintenance;
• In Renewables & Energy, we want to grow gradually and consistently, increasing the relative weight of this business unit in the Group, taking advantage of the opportunities associated with energy transition, decarbonisation of the economy and hydrogen (through the Green.H2.Atlantic consortium of which we are part);
• Define quantitative targets for the next strategic cycle, monitored by the ESG & Sustainability Committee, and, above all, consolidating sustainable value creation as the Group's main strategic purpose.
