A Natural Climate Solution

Fremantle Seaweed is on a mission to help Australia’s cattle farmers become climate heroes. We cultivate the native red seaweed, Asparagopsis, in Western Australia’s pristine ocean waters and process it into a feed additive that can reduce methane emissions from cattle by over 80%.

Methane is over 28 times more potent than CO₂, and livestock emissions make up 5% of global greenhouse gases - more than aviation, shipping, and rail combined. Our ocean-grown approach offers a lower-cost, scalable alternative to onshore systems, harnessing nature to solve agriculture’s biggest emissions challenge.

Why Invest Now

  • Proven science: Just 63g/day of Asparagopsis per cow can reduce methane by over 80% demonstrated by CSIRO, James Cook University and MLA.
     
  • Commercial traction: First trial with two of WA’s leading Wagyu producers progressing to prove research showing Asparagopsis improves feed efficiency by 7%.
     
  • Government backing: Awarded $4M non-dilutive grant, with potential $3M matched funding.
     
  • Scalable model: Plans underway for a 3,000ha site capable of servicing 21% of the Australian market.
     
  • First mover: Only Australian producer cultivating both species of Asparagopsis entirely in the ocean.

Seaweed for the cows

We grow Asparagopsis seaweed offshore, where it naturally thrives, then process it into a premium, freeze-dried feed additive for cattle. Our ocean-based model is less capital-intensive than onshore tanks or ponds, requires fewer inputs, and reduces contamination risks.

By working in harmony with the ocean, we’re building a sustainable supply chain that supports farmers, delivers measurable emissions reductions, and positions Western Australia as a leader in the global seaweed industry.

A $37B Global Market

The global market for Asparagopsis feed additives is estimated at $37.44B, driven by rising demand for methane reduction in cattle. In Australia alone, the addressable market is $510.49M, with strong adoption potential as exporters, supermarkets, and financiers push for carbon-neutral supply chains.

Consumers are ready with 26% already choosing sustainable beef, and many are willing to pay more for low-emissions products. With limited supply available, Fremantle Seaweed is positioned to fill a critical gap in a rapidly expanding sector.

Progress That Speaks Volumes

  • Established 32ha pilot site in WA’s “goldilocks zone” for year-round cultivation.
  • Achieved Australian-first: successful ocean-grown tetraspores to full plant.
  • $1M+ invested in R&D; $4M WA Government grant awarded. - Secured letter of intents for commercial trials with Pardoo Wagyu and Kylagh Cattle Co.
  • Accepted into KPMG High Growth Ventures Program.
  • Winners of OCC Ocean x Climate Solution award; finalists in Ocean Community Challenge.
  • FutureFeed Cooperation Agreement in place

Built for Scale and Impact

Our fully ocean-based model mirrors the way 98% of the world’s seaweed is grown — reducing costs, inputs, and environmental footprint compared to onshore production. We are the only Australian producer cultivating both Asparagopsis taxiformis and Asparagopsis armata in one location, enabling yearround production.

With proven cultivation methods, unmatched coastal access, and strong industry partnerships, Fremantle Seaweed is positioned to lead the Australian Asparagopsis sector at commercial scale.

IP

In the risk section - FutureFeed owns the right to market - the mitigation says there is a cooperation agreement but not a commercial agreement. To your knowledge, has FutureFeed granted a commercial license to Freemantle's competitors? What are the reasons that they would not grant a license? Do they get a "clip of the ticket" as being the owner of the right to market?

And is there any other IP that is owned by Freemantle - such as method of growing, processing etc.

mary sue r (OnMarket member) on 26/09/2025

Hi Mary Sue,

FutureFeed owns the global IP to feed Asparagopsis to cattle, and to sell Asparagopsis to cattle, Fremantle Seaweed will need to become a licensee (under a licensee agreement). We have a cooperation agreement with FutureFeed which is similar to an MoU, and enables us to complete a commercial feedlot trial to progress to a full licensee agreement. It's a bit of the process but the intent is to show that we can supply to the customer, complete our product formulation (as per the 6mg/g of bromoform required by FutureFeed) and dose the supplement correctly. Once we have completed the commercial feedlot trial we will move to a commercial licensee agreement.

FutureFeed have granted 9 licenses to Asparagopsis cultivation companies: https://www.future-feed.com/industrypartners and it is their best interest to grant further licenses to proponents who can show they can complete the steps required for a successful feedlot trial.

FutureFeed have a royalty model that means they take a small percentage of revenue from licensees.

We have some details of our IP strategy in the offer document. Due to the current early stages of Asparagopsis cultivation, there are significant unknown opportunities. We have identified the following key areas for IP Commercialisation Opportunities:
Hatchery and Nursery:
the protocols to produce consistent seeded substrate with a high survivability rate have been developed by the Australian Sustainable Seaweed Alliance (ASSA) with the open-sourced National Hatchery Network Manual released early June 2025. This provides instruction for FS to develop our own capability and skills (people) and a starting point to develop our own hatchery and nursery protocols to produce higher yielding seeded substrate. Any IP developed will owned by FS.
Asparagopsis strain yields: like terrestrial crops, high performing seaweed strains can be identified and protected. The protocols to develop these strains is related to the Hatchery and Nursery IP.
Marine operations: the ability to efficiently seed and harvest Asparagopsis seaweed on aquaculture equipment will be under constant development over the coming years. FS is well positioned to develop equipment designs that target Asparagopsis growth.
Vessel capabilities: to grow at scale, modern vessels with on deck machines and automation will be designed and built to reduce the human resources required for aquaculture operations.

I'll respond to your email too!

Kind regards,

Chris de Cuyper

ROI

Hi,
Wondering what the process is for getting a ROI for investing? Is the plan to take the company public at some stage at this share price? Or will shareholders be rewarded some other way?
Thanks

Brandon P (OnMarket member) on 02/10/2025

Hi Brandon,

Fremantle Seaweed doesn't have any immediate plans for an exit or a liquidity event but this is an aim over the medium/long term event if we are able to achieve our goals.

There is no guarantee that an exit event will occur but, if it does, it could be in the form of a:

- trade purchase of Fremantle Seaweed
- listing on the ASX or other stock exchange;
- private equity investment in Fremantle Seaweed; or
- a share buy-back by Fremantle Seaweed.

Additionally, a return could potentially come from the pay out of dividends if and when we achieve profitability (although note that a decision to pay dividends is subject to the directors discretion and obligations under the Corporations Act). All shareholders have a right to receive any dividends declared and paid by Fremantle Seaweed.

You can read more about the exit opportunities and rights associated with shares in section 2.5.10 and 3.3 of the Offer Document respectively.

Kind regards,
May
