Northern Technologies International Corporation reported higher sales but lower profit for the quarter ended November 30, 2025. Net sales rose 9.2% to $23.3 million, driven mainly by 11.9% growth in ZERUST® corrosion products and 2.2% growth in Natur-Tec® bioplastics. ZERUST® oil and gas revenue jumped 58.1%, helped by strong demand in Brazil.
Despite this, net income attributable to NTIC fell to $237,819, or $0.03 per diluted share, from $561,091, or $0.06 per share, as higher cost of goods sold, increased operating expenses, and higher interest expense offset the sales gains. Gross profit was $8.4 million and income before income taxes was $770,908.
