Methane-reducing feed additive developer Sea Forest is set to debut on the ASX on 26 November 2025 after completing a fully underwritten $20.5 million Initial Public Offering. The float values the Tasmanian company at approximately $112.1 million at the offer price of $2.00 per security.
Founded in 2018, Sea Forest developed SeaFeed, the world’s first livestock feed additive formulated to replicate the methane-inhibiting properties of Asparagopsis seaweed. The product is scientifically validated to cut methane emissions in cattle by up to 80 per cent while also improving saleable meat yield.
Funds raised through the IPO will accelerate the company’s commercial scale-up, including expanding production capacity across Australia and overseas. Facilities are planned for Queensland, New South Wales, Western Australia and in South Africa.
Investment will also support regulatory approvals, new product development, and working capital requirements.
CEO and co-founder Sam Elsom said the company was well positioned to scale demand for methane-reducing inputs across domestic and global markets.
Sea Forest has already secured supply agreements with major livestock producers and global brands including Teys Australia, Chadwick Consolidated Group, Ashgrove Cheese, Grill’d, Olsson’s, Orffa, Fast Retailing (Uniqlo), and Morrisons UK.
Existing contracts cover supplementation for around 100,000 head of livestock, with discussions underway for an additional 700,000.
“We’re driving measurable productivity gains at the farm gate, with the added benefit of up to an 80 per cent reduction in methane emissions.
“As we take the next step in our journey as a listed company, our focus is on scaling operations, advancing research, and strengthening partnerships,” Elsom said.
Chair John McKillop said Sea Forest represented a genuine step change for agricultural sustainability, backed by strong scientific evidence and commercial traction.
“The industry is under pressure to produce more with less and do it more sustainably. Sea Forest directly addresses these challenges and enables farmers to reduce Scope 3 emissions and access premium low-emission markets,” McKillop said.
New investors will hold around 18.3 per cent of the company post-listing. Around 97.6 per cent of existing shareholder securities will be subject to escrow arrangements. The company’s shares will trade under the ticker SEA.
“The business case is compelling and we’re seeing increased interest and adoption in our products because it’s good for business and good for the environment,” Elsom said.
