MINNEAPOLIS, Nov. 18, 2025 (GLOBE NEWSWIRE) — Northern Technologies International Corporation (NASDAQ: NTIC), a leading developer of corrosion inhibiting products and services, as well as bio-based and biodegradable polymer resin compounds, today reported its financial results for the fourth quarter and fiscal year ended August 31, 2025.

Full year fiscal 2025 financial and operating highlights include (with growth rates on a fiscal year-over-year basis):

• Consolidated net sales decreased 1.0% to $84,234,000
• ZERUST® industrial net sales increased 2.4% to $55,171,000
• ZERUST® oil and gas net sales decreased 20.7% to $7,318,000
• Natur-Tec® product net sales decreased 1.0% to $21,746,000
• NTIC China net sales increased 14.0% to $16,240,000
• Gross profit, as a percent of net sales, decreased 210 basis points to 37.6%
• Joint venture operating income decreased 9.8% to $8,545,000
• Operating income decreased 67.3% to $2,570,000
• Net income attributable to NTIC was $18,000, compared to $5,409,000
• Net income per diluted share attributable to NTIC was $0.00, compared to $0.55
• Cash provided by operating activities was $2,389,000 for the twelve months ended August 31, 2025

“Challenging market conditions and the shifting timing of certain ZERUST® oil and gas and Natur-Tec® orders impacted sales throughout fiscal 2025. Nevertheless, we continued to bolster our foundation and invest in business development initiatives globally that we expect to position us for renewed growth in fiscal 2026 and beyond. This included applying our considerable engineering capabilities to develop new Natur-Tec® technologies, pursuing emerging opportunities in the South American offshore oil and gas market, and expanding ZERUST® industrial sales across our global footprint. NTIC’s recently announced milestone multi-year order from a major international EPC in Brazil underscores the growing recognition of our corrosion solutions and validates our strategy to expand into key global energy markets. Consequently, we believe our pipeline of opportunities within ZERUST® oil and gas and Natur-Tec® is strong,” said G. Patrick Lynch, President and CEO of NTIC.

“In fiscal 2026, we also expect to start reaping the benefits gained from the strategic investments NTIC made over the past three years to upgrade our global operations and support future growth. We are also focused on flattening our operating expenses while expanding gross margins and driving sales in higher-margin parts of our business, which we expect will improve our profitability and strengthen our balance sheet in fiscal 2026. While we anticipate macroeconomic headwinds to persist, especially in Europe, we believe NTIC is positioned to deliver growth and improved profitability across many of our key markets in the coming fiscal year,” concluded Mr. Lynch.

NTIC’s consolidated net sales decreased 4.4% to $22,315,000 during the three months ended August 31, 2025, compared to $23,349,000 for the three months ended August 31, 2024. The year-over-year decline in fourth-quarter sales was primarily driven by lower ZERUST® oil and gas sales due to a significant one-time order recognized during fourth quarter of the prior fiscal year and softer Natur-Tec® sales resulting from pricing dynamics and order timing during fourth quarter of fiscal 2025. For the full year ended August 31, 2025, consolidated net sales decreased 1.0% to $84,234,000, compared to $85,060,000 for the prior fiscal year.

The following tables set forth NTIC’s net sales by product category for the three months and fiscal year ended August 31, 2025 and 2024, by segment:

Net sales of NTIC’s joint ventures, which are not consolidated with NTIC’s financial results, increased 4.7% to $24,388,000 during the three months ended August 31, 2025, compared to $23,297,000 for the three months ended August 31, 2024. NTIC’s joint venture operating income increased 6.6% to $2,168,000 during the three months ended August 31, 2025, compared to joint venture operating income of $2,034,000 during the three months ended August 31, 2024. The $134,000 increase in joint venture operating income was primarily due to a corresponding increase in net sales.

For the full fiscal year 2025, NTIC’s joint venture operating income decreased 9.8% to $8,545,000, compared to joint venture operating income of $9,475,000 for the prior fiscal year. Net sales of NTIC’s joint ventures decreased 4.9% to $91,236,000 for the full fiscal year 2025, compared to $95,940,000 for the prior fiscal year.

Operating expenses, as a percentage of net sales, for the fourth quarter of fiscal 2025 were 43.5%, compared to 40.7% for the same period last fiscal year. For the full fiscal year 2025, operating expenses, as a percentage of net sales, were 44.7%, compared to 41.6% for the full fiscal year 2024. Higher operating expenses for the three and twelve months ended August 31, 2025 were primarily due to strategic investments in ZERUST® oil and gas sales infrastructure and increased personnel expenses, including new hires, benefits, and higher travel and professional fees.

NTIC recognized $1,140,000 in other income during the twelve months ended August 31, 2025, due to the receipt of a cash employee retention credit payment. NTIC recognized $387,000 in other expense during the twelve months ended August 31, 2025, as during the fourth quarter of fiscal 2025, NTIC’s Chinese subsidiary was assessed $387,000 in penalties from Ningbo Customs, a customs authority in China, as a result of a technical classification matter. NTIC has updated its export documents and internal review procedures and believes the issue has been fully resolved.

NTIC’s effective income tax rate increased to 67.5% for fiscal 2025 from 17.3% in the prior fiscal year. The increase primarily reflects income taxes paid at NTIC’s foreign subsidiaries at normal statutory rates, as well as withholding taxes on royalty and dividend payments. This increase in tax expense was partially offset by tax benefits in North America due to losses for which no corresponding tax benefits or deferred tax assets were recognized. As a result, NTIC’s effective tax rate was unusually high and volatile for the year. Management expects the effective tax rate to normalize in future periods when additional profits are recognized in North American operations.

Net loss attributable to NTIC for the fourth quarter of fiscal 2025 was $(1,100,000), or $(0.12) per diluted share, compared to net income of $1,836,000, or $0.19 per diluted share, for the same period last fiscal year. For the full fiscal year ended August 31, 2025, net income attributable to NTIC was $18,000, or $0.00 per diluted share, compared to net income of $5,409,000, or $0.55 per diluted share, for the full fiscal year ended August 31, 2024.

NTIC’s non-GAAP adjusted net loss, as set forth in the GAAP reconciliation at the end of this release, was $(607,000), or $(0.06) per diluted share, for the fourth quarter of fiscal 2025, compared to $1,942,000, or $0.20 per diluted share, for the same quarter last fiscal year. For the full fiscal year ended August 31, 2025, non-GAAP adjusted net loss was $(12,000), or $(0.00) per diluted share, compared to net income of $5,832,000, or $0.59 per diluted share, for the full fiscal year ended August 31, 2024.

NTIC had working capital of $20,439,000 as of August 31, 2025, including $7,251,000 in cash and cash equivalents and an outstanding revolving line of credit and term loan balance of $12,656,000, compared to $23,682,000 of working capital as of August 31, 2024, including $4,952,000 in cash and cash equivalents and an outstanding revolving line of credit and term loan balance of $7,112,000.

At August 31, 2025, NTIC had $28,612,000 of investments in joint ventures, of which $14,800,000, or 51.7%, is cash, with the remaining balance mostly made up of other working capital.

(UNAUDITED, IN THOUSANDS, EXCEPT SHARE AND PER SHARE AMOUNTS)

The accompanying press release contains certain non-GAAP financial measures, including adjusted net (loss) income attributable to NTIC and adjusted net (loss) income attributable to NTIC per diluted share, which are not calculated or presented in accordance with accounting principles generally accepted in the United States (GAAP). These non-GAAP financial measures are supplemental information and in addition to the financial measures presented in the accompanying release that are calculated and presented in accordance with GAAP.

NTIC also believes that the presentation of certain non-GAAP financial measures provides useful information to investors in evaluating the company’s operations, period over period. Such non-GAAP financial measures should not be considered superior to, as a substitute for, or as an alternative to, and should be considered in conjunction with, the GAAP financial measures presented in the release. The non-GAAP financial measures in the accompanying release may differ from similar measures used by other companies.

The following is a reconciliation of NTIC’s reported net (loss) income attributable to NTIC and reported net (loss) income attributable to NTIC per diluted common share to adjusted net (loss) income attributable to NTIC and adjusted net (loss) income attributable to NTIC per diluted common share, in each case, as adjusted to exclude the contribution from the receipt of an ERC payment, customs classification adjustment and related penalties, and amortization expense.
