## Overview

SeaTwirl is a Swedish public company developing floating wind turbines based on a vertical-axis design that rotates with its floating structure and keel as one unit. The company is headquartered in Gothenburg and its shares trade on Nasdaq First North Growth Market under the ticker STW.

## Products & services

• Floating vertical-axis wind turbine development
• Prototype design and testing
• Offshore demonstration units
• Technology licensing and partnership development
• Patent and IP development

- **Floating wind turbine development** (70%) — Design and engineering of SeaTwirl's floating vertical-axis wind turbine concept.
- **Prototype and demonstration systems** (20%) — Build and operation of test units used to validate the technology in marine conditions.
- **IP and patent-related activities** (10%) — Development and protection of technical know-how, patents, and related rights.

- Floating vertical-axis wind turbine development
- Prototype design and testing
- Offshore demonstration units
- Technology licensing and partnership development
- Patent and IP development

## Customers

SeaTwirl's direct customers are not yet commercial end-users in the traditional sense; the company is still developing and validating its turbine technology. Its commercial counterparties are typically utilities, energy developers, industrial partners, and strategic collaborators that could adopt, license, finance, or co-develop future offshore wind projects.

- **Utilities and renewable power developers** (primary) — Would buy or deploy SeaTwirl turbines for offshore power generation if the technology is commercialized.
- **Strategic industrial partners** (secondary) — Partner on market access, localization, and commercialization, such as the Japan MoU disclosed in reports.
- **Research and grant consortia** (secondary) — Support development programs and demonstration projects that fund technical validation.
- **Future licensees and project developers** (emerging) — May adopt the technology through licensing, joint ventures, or project-specific deployments.

- Utilities and power developers evaluating offshore wind technology
- Industrial partners seeking co-development or market access
- Government and research consortia supporting R&D projects
- Potential licensees or EPC partners for future commercialization
- Investors and grant-funded programs financing development

## Geography

SeaTwirl is based in Sweden, with its headquarters in Gothenburg and early prototype activity tied to the Swedish coast near Lysekil. The company has also disclosed commercial outreach in Japan through a memorandum of understanding with a Sumitomo Corporation subsidiary, indicating an international commercialization path.

- **Sweden** (100%) — Headquarters and prototype activity are in Sweden; no revenue geography disclosed.

- Headquartered in Gothenburg, Sweden
- Prototype S1 installed offshore near Lysekil, Sweden
- Nasdaq First North Growth Market listing in Sweden
- Japan is an identified commercialization market
- Future offshore projects are likely to be international

## Strategy

SeaTwirl's strategy is to advance its floating wind platform from prototype validation toward larger commercial turbines that can be deployed in different sites and applications. The company also pursues partnerships and market access agreements to prepare for commercialization in target offshore wind markets such as Japan.

- **Scale the technology to larger commercial units** (medium-term) — Commercial viability depends on proving the design at larger turbine sizes.
- **Use partnerships to enter target markets** (short-term) — Local partners can accelerate market access, customer validation, and deployment.
- **Secure funding for continued development** (short-term) — The business model requires capital before meaningful commercial revenue arrives.

- Scale the turbine concept from prototype to larger units
- Validate performance in real offshore conditions
- Build partnerships for market access and commercialization
- Protect and expand the technology through patents and IP
- Pursue external funding to support development work

## Risks

SeaTwirl faces the typical risks of a pre-commercial development company: technology may not scale as planned, commercialization may take longer than expected, and future revenue may remain limited. The company also depends on external financing, so dilution and funding availability are central risks, while offshore wind projects carry technical, regulatory, and market-adoption uncertainty.

- **Pre-commercial revenue risk** [high] — The company has not yet launched a commercial wind turbine, so sales may remain limited or delayed.
- **Financing and dilution risk** [high] — Development spending must be funded before commercial cash flow exists, often through new equity or other financing.
- **Technology scale-up risk** [high] — Prototype success does not guarantee performance, reliability, or economics at larger turbine sizes.
- **Offshore project execution risk** [medium] — Marine installations face weather, engineering, permitting, and logistics complexity.

- No commercial turbine sales yet, so revenue visibility is limited
- Future funding needs may require equity issuance and dilution
- Technology may not scale from prototype to commercial size
- Offshore wind adoption depends on regulation and project economics
- Partnerships may not convert into commercial orders

## Accounting

SeaTwirl's reporting is shaped by capitalized development costs, which can materially affect the balance sheet and future amortization or impairment charges. Because the company is still pre-commercial, revenue is sparse and results are driven by R&D spending, while judgments around capitalization, patent assets, and impairment testing are especially important.

- **Capitalized development costs** — Development asset balance and future impairment risk
- **Patent and intangible asset accounting** — Intangible asset carrying value
- **Impairment assessment** — Earnings volatility
- **Share-based compensation** — Operating costs and share count

- Capitalized development costs are a major balance-sheet asset
- Patent-related capitalization affects intangible asset values
- Impairment testing is important if project economics change
- Sparse revenue makes expense timing more visible in results
- Share-based compensation can affect reported operating costs
