2024 Financial and Operational Highlights:

·    Revenue Growth and Commercial Expansion:

Revenues increased by 70% to $2.0 million (2023: $1.2 million), driven by an 81% increase in hospital deployments and higher per-hospital revenue year-over-year despite a 40% reduction in sales and marketing spend. In the UK, Steriwave^® became the first light-activated antimicrobial listed on NHS Supply Chain, enabling streamlined access for hospitals across England and Wales.

·    Strategic Distribution Partnership:

Established a strategic distribution partnership with Mölnlycke Health Care, a world-leading MedTech company, to accelerate international reach for Steriwave into key markets, including the United Kingdom (UK), European Union (EU), and Middle East. Mölnlycke products and solutions are used daily by hospitals, health care providers and patients in over 100 countries around the world.

·    Margin Expansion:

Gross margin improved to 64% (2023: 58%) as a result of operational efficiencies and the introduction of the enhanced Steriwave nasal illuminator, which is designed for enhanced performance, high-volume manufacturing, and improved margins.

·    Capital and Funding:

Successfully raised $21.7 million net cash during 2024, with a further $5.7 million in strategic investment from a leading US healthcare entity shortly after the 2024 financial year-end, providing essential funding to initiate the Phase 3 clinical trial and support continued commercial expansion of Steriwave.

·    Clinical Progress:

The pivotal US Phase 3 LANTERN clinical trial commenced with the first patient enrolled in December 2024. Early recruitment experiences informed efforts to optimize protocols, processing, and overall trial plans. Patient recruitment is actively progressing at 10 of the 14 planned HCA Healthcare hospitals, with additional site activations pending and further sites contemplated. With these measures, the Company anticipates last patient recruitment will be delayed by approximately one quarter. 

The Company agreed a clinical development program with the Royal Columbian Hospital Foundation, enabling acceleration of entry into the ICU market. The four-month ICU pilot trial began patient recruitment post-period, in March 2025.

·    R&D and Operating Expenses:

Operating loss was $19.4 million (2023: $14.8 million), reflecting increased and upfront investment in clinical trials, FDA audit readiness, and operational infrastructure to support future growth.
