Northern Technologies International Corporation reported higher sales but lower earnings for the quarter and nine months ended May 31, 2026. Net sales rose to $24.2M for the quarter and $69.5M year-to-date, up about 13% from the prior-year periods, driven by both ZERUST® and Natur-Tec® products.
Despite growth, profitability weakened. Quarterly net loss attributable to NTIC was $263,291 (basic and diluted loss of $0.03 per share) versus prior-year income, and year-to-date net loss was $60,795 compared to income of $1.12M. Gross margin declined as cost of goods sold rose faster than sales and prior-year other income from Employee Retention Credits did not repeat.
ZERUST® sales increased to $18.1M in the quarter, including strong oil and gas growth, while Natur-Tec® reached $6.1M. Operating cash flow turned negative at $(0.76)M for the nine months. Debt increased, with $11.76M outstanding under the revolving credit facility, and the company breached its Fixed Charge Coverage Ratio covenant (0.68 vs. 1.25) but obtained a waiver. To prioritize debt reduction, the Board suspended the quarterly cash dividend starting with the third quarter of fiscal 2026.
Northern Technologies International Corporation reported third quarter fiscal 2026 results showing solid revenue growth but weaker profitability. Consolidated net sales rose 12.6% year-over-year to $24,215,662, a quarterly record driven by strong demand for ZERUST® corrosion prevention and Natur-Tec® bioplastic products. ZERUST® oil and gas net sales jumped 72.3% to $2,219,342, while total Natur-Tec® net sales increased 5.0% to $6,070,051. Despite this growth, gross margin declined 477 basis points to 33.6% due to higher raw material costs and pricing pressure, leading to a net loss attributable to NTIC of $263,291, or $(0.03) per diluted share, versus net income of $121,775, or $0.01 per diluted share, a year earlier. Year-to-date, sales rose 12.3% to $69,521,265, but NTIC posted a small net loss of $60,795.
