▪ Extended hedging period to fully cover 2020

▪ Increased volume coverage … Higher volume of 7.7 kt/month or 92.4kt/year (vs previous 6.1 kt/month or 73.2 kt/year) … approx. 70% of zinc equivalent payable output

▪ Strong hedge price levels of €2,306/t in 2019 and €2,245/t in 2020

• Preliminary FY '17 Earnings increased to €172m / +30% YoY Adjusted EBITDA (24% of revenue) … €144m / +39% YoY Adjusted EBIT (20% of revenue) …

Clients

Crude Steel Plants Salt Slags Plants

Befesa offers a crucial service taking care of highly regulated hazardous waste in the value chain of secondary steel and aluminium producers

• Befesa collects and recycles hazardous waste from steel producers and aluminium recyclers
• Recycling is mandatory for Befesa's clients due to environmental regulations
• Befesa takes off and effectively takes care of environmental liability for their clients
• Without timely and regulatory compliant offtake of hazardous waste clients face risk of complete shut-down of production as well as severe penalty payments
• Befesa therefore offers a critical element of its clients value chain

Consequences of Non-Compliance

• Major European steel producer struggles with large plant (producing 8% of European steel) due to breaching environmental regulations (contamination of environment)
• Court ordered to partly shut down the plant
• Owner prompted to invest \$3.8bn to bring the plant back to required standards
• In 2002 the owners of a metal foundry in Italy faced prison time for illegal transport and landfilling of hazardous waste
• In 2004 a big aluminium refinery in Italy abandoned 450kt of hazardous waste in the open air over half an hectare
• More than 10 years later the local administration is still collecting funds to proceed to the removal and cleaning of the area
• In 2011 a big producer of aluminium alloys in Spain was involved in the transport without authorisation and illegal landfilling of 1.5kt of salt slags on a vacant lot
• Befesa was ultimately contracted to treat the waste properly

Befesa's services business is inherently protected by high barriers to entry

Customers

• Steel and aluminium producers:
• Befesa has a strong position in servicing the steel and aluminium manufacturers with long-term relationships: often +15 years
• Zinc smelters, aluminium producers:
• Befesa provides commoditized but scarce products with an outlook of growing demand – Zinc Oxide sold out

New Entrants – High Barriers to Entry

• Technology and process know-how
• Capital intensity to build new plant
• Regionally the capacity is balanced
• New license difficult to get
• Vertical integration lacks economy of scale

Concentrated Market

Befesa is the clear leader in niche recycling industries with few players

Substitution Risk – Very Low

• Strictly enforced regulation in the European Union
• No viable alternative to recycling

Suppliers – Limited Bargaining Power

• Low differentiated product (e.g. utilities, water, basic materials)
• Low switching costs to another supplier

High Entry Barriers and Regulatory Certainty Around Recycling Services Provide a Highly Defendable Market Position for Befesa

Attractive growth track record with stable margins and strong cash generation

Low capital intensity exemplified by low, stable D&A and high Adj. EBIT margin

Strong and stable free cash flow generation due to low maintenance requirements providing funds for growth

Robust sales growth underpinned by sustainable increase in volumes and acceleration in growth in 2017

BEFESA Resilience Underpinned by Service Business Model 5

Befesa is a service company managing and reducing exposure to commodity prices

Portfolio Mix	Steel Dust Recycling Services and Aluminium Salt Slags Recycling Services with limited correlation • • In 2015–2017 zinc and aluminium prices have shown inverse margin trends
Collection Fee	• Steel dust collection fee (~10-20% revenues) influenced inversely by zinc prices • Salt slags collection fee (~40% revenues) uncorrelated to aluminium prices
Salt Slags	• Low to no commodity risk as recycled aluminium concentrates used for own production and only recycled salt sold externally (~20% of segment revenues)
Secondary Aluminium	• "Natural hedge" as aluminium is both an input (COGS) and an output (sales). Further, own secondary production highly complementary to salt slags business
Zinc Floor	• Marginal cost of mines has been steadily increasing as old low cost mines are shut down; floor price for zinc (reduces volatility) further supported by supply/demand shortages • Zinc price floor estimated to be around €2,000-2,100 per ton for next years
Hedging	Befesa reduces earnings variability by buying floors and swaps (24-48 months out) providing for minimum floor EBIT • with additional upside Zinc price volatility: Average inter annual swings of ~10-12% since 2008 •

Accelerated top- and bottom-line growth through a well-defined strategy
