Clean Seed Capital Partners with ClimateDoor to Launch Soil and Sky Alliance

VANCOUVER, BRITISH COLUMBIA — May 13, 2026 — Leads & Copy —

Clean Seed Capital Group Ltd. (NEX: CSX.H) is partnering with ClimateDoor Partners Inc. to launch Soil and Sky Alliance (SASA) and has entered into a specialty license and distribution agreement with SASA, according to a recent announcement from Clean Seed.

SASA, a climate agriculture infrastructure company, will develop a specialty platform integrated onto the Clean Seed Mini-MAX™ to launch, deploy, and distribute a specialty Mini-MAX product line (“SASA Certified MAX”) focused on measuring, monitoring, and reporting on environmental outcomes for seeding operations. The SASA Certified MAX is designed to support sustainability reporting, environmental measurement initiatives, and potential future carbon-market participation.

The partnership with ClimateDoor creates a pathway for the deployment of Mini-MAX™. SASA represents a milestone in the continued commercialization and international deployment of Clean Seed's Mini-MAX™ precision seeding technology platforms.

Under the agreement, Clean Seed will grant SASA an exclusive specialty license for the Mini-MAX™ to develop the SASA Certified MAX. SASA will purchase Mini-MAX™ units from Clean Seed, add the SASA Certified MAX components, and distribute the SASA Certified MAX units to its customers. This allows SASA to leverage Clean Seed's Mini-MAX™ technology, manufacturing partnerships, and operational infrastructure to accelerate international commercialization and large-scale deployment. SASA will also be issued a non-exclusive license to purchase and distribute the Mini-MAX™ product line into open distribution territories.

Mini-MAX™ units sold to SASA will be manufactured by Mahindra and Mahindra Limited, which will support future scale-up and international deployment opportunities associated with the SASA initiative.

In consideration for the agreement, Clean Seed will own 25% of the common shares of SASA, aligning its technology with the long-term performance of SASA.

The agreement is for an initial term through 2030 and includes minimum Mini-MAX™ purchase commitments for SASA to maintain exclusivity rights. Upon completion of its purchase commitments, SASA can expand its license to produce Mini-MAX™ units independently and pay Clean Seed a royalty based on total sales generated by SASA. Closing of the agreement is expected in May 2026, pending completion of closing conditions, including SASA issuing its common shares to Clean Seed.

Graeme Lempriere, Chairman and CEO of Clean Seed, stated that the partnership represents more than equipment deployment. He noted that ClimateDoor and the SASA team bring knowledge and vision to the environmental solutions space and that their commitment to climate-impact initiatives, sustainability infrastructure, and regenerative agriculture aligns with Clean Seed's mission of building and deploying technologies that create economic and environmental value for farming communities globally.

The initial rollout of the SASA program is focused on Brazil, where Clean Seed and SASA teams are advancing deployment initiatives with agricultural stakeholders, research organizations, governmental bodies, and farming groups. Eight Mini-MAX™ units in Brazil will be purchased by SASA for deployment under SASA's first regional deployment campaign in 2026. SASA is evaluating program opportunities in Kenya and India for 2026.

Lempriere added that the future of agriculture will be defined by sustainability, accountability, precision, and environmental intelligence. He believes ClimateDoor's ecosystem and strategic vision provide a platform to accelerate that future. SASA has the potential to connect advanced agricultural technologies with environmental finance groups and global food-security initiatives.

Chad Rickaby, Chairman of SASA and CEO of ClimateDoor, said that Brazil is the first market because the agronomic case stacks. He stated that fertilizer shocks have made input efficiency a food security issue and that the Mini-MAX™ delivers measurable nitrogen efficiency, soil carbon retention, and burn reduction. He added that the technology is ready and that their job is to build the business models and capital structures to get this machine into farmers' hands at the speed the moment demands, in Brazil first, then wherever smallholders are exposed.
