With this new agreement, Sea Forest now has arrangements covering approximately 118,000 head of livestock to be supplemented with SeaFeedTM . Sea Forest’s existing customers manage, source cattle from or have supply relationships encompassing over 250,000 head of livestock, representing a strong pipeline of additional revenue opportunities. SOUTH AMERICA MARKET ENTRY WITH BELTERRA AGROFLORESTAS PARTNERSHIP Sea Forest has entered a landmark strategic partnership with Belterra Agroflorestas (Belterra), a leading Brazilian climate solutions company, marking Sea Forest's entry into South America and Brazil. Brazil is the world’s largest livestock market with approximately 238 million head of cattle and approximately 22 million head of sheep3. Under this agreement, Belterra will collaborate with Sea Forest to promote SeaFeed™, within their network of agricultural producers, including Rio Capim Farmers, delivering material emissions reductions and supporting scalable livestock decarbonisation.

Brazil is the world’s leading beef producing country, with livestock farming contributing substantially to the national economy and export revenues. The country has committed to reducing its methane emissions by 30%4 as part of the Global Methane Pledge, with agriculture responsible for 75% of the country’s emissions, reflecting a significant opportunity for carbon abatement technologies such as SeaFeedTM.
