Aquaporin A/S announced Friday that it has withdrawn its previously announced rights offering and will move forward with insolvency proceedings, citing an inability to secure sufficient funding to continue operations.
The Denmark-based company said its board determined that the offering, announced in December, would not meet its near-term working capital needs for 2026, despite receiving some investor support. The board now plans to file for bankruptcy and request the appointment of a trustee in the coming days. Trading in the company’s shares is expected to be suspended by Nasdaq Copenhagen.
Aquaporin was best known for its nature-inspired membrane technology, which incorporated aquaporin water-channel proteins—biological structures responsible for rapid, selective water transport in living cells—into synthetic filtration membranes. The approach aimed to improve water permeability and selectivity while reducing energy demands in applications including reverse osmosis and forward osmosis.
The company positioned the technology for use in industrial water treatment, wastewater concentration, and food and beverage processing, particularly in applications where conventional membranes face efficiency or energy limitations. Despite years of development and pilot activity, Aquaporin said it was unable to secure sufficient financing or strategic partnerships to scale commercialization of the platform.
The full company announcement is available via the original press release.
