LiqTech International, Inc. is a Nevada‑incorporated clean technology company headquartered in Denmark that designs and manufactures silicon carbide ceramic membranes, diesel particulate filters, and integrated liquid filtration systems. It serves industrial wastewater, oil & gas, marine, commercial pool, and other demanding applications, supported by plastics manufacturing and in‑house systems engineering.
The company highlights competitive strengths in patented SiC technology, vertical integration, and global distribution, but also discloses significant risks. These include a continued need for substantial capital and access to financing, exposure to energy price volatility in Europe, global trade restrictions, pandemics, and geopolitical conflicts. LiqTech depends on a small number of major customers, faces supply chain and raw material cost risks, and operates in highly regulated markets where tightening or changing environmental and trade rules can affect demand. It also notes past material weaknesses in internal control over financial reporting, intense competition, IP protection challenges, cybersecurity threats, foreign currency fluctuations, and common stock risks such as dilution, low trading volume, and price volatility.
LiqTech International, Inc. is expanding its Board of Directors and strengthening governance. The company’s board approved the appointment of Robert (Bob) Wowk as a director, effective March 1, 2026, increasing the board size from five to six members.
Wowk will also serve on the Audit Committee and Compensation Committee, and will receive compensation consistent with other independent directors. He brings over 30 years of finance and business development experience in industrial gas and renewable energy sectors, including senior roles at Linde, Gulf Cryo, Air Products and CFO positions at multiple clean‑tech companies.
The board determined that Wowk qualifies as an independent director under SEC and Nasdaq rules. A press release dated February 18, 2026 provides additional background on his experience and highlights the board’s expectation that his industrial and global expertise will support LiqTech’s growth strategy in advanced filtration and clean technology markets.
