“NTIC’s second-quarter performance demonstrates the increasing intensity of the headwinds we are currently facing,
including recent changes in U.S. trade and economic policies, the seasonality of our industrial and oil and gas businesses, and the timing of certain Natur-Tec® orders. Despite these current headwinds, we believe we are poised for a rebound in Natur-Tec® and ZERUST® oil and gas sales in the second half of the fiscal year,” said G. Patrick Lynch, President and CEO of NTIC.

“As we navigate this dynamic global environment, we are unwavering in our commitment to delivering long-term value. Our disciplined approach to managing cash, including temporarily adjusting our quarterly dividend to $0.01 per share effective with our next quarterly dividend, and prioritizing debt reduction are intended to position us to seize future growth opportunities in our oil and gas and compostable plastics businesses. We believe that our strategic growth priorities and financial discipline will drive sustainable growth and long-term shareholder value,” concluded Mr. Lynch.

NTIC’s consolidated net sales decreased 8.5% to $19,072,000 during the three months ended February 28, 2025, compared to $20,843,000 for the three months ended February 29, 2024. This decrease was primarily a result of lower sales within the Company’s ZERUST® oil and gas, Natur-Tec®, and ZERUST® industrial product categories. For the first half of fiscal 2025, consolidated net sales decreased 1.5% to $40,410,000, compared to $41,024,000 for the same period last year.

The following tables set forth NTIC’s net sales by product category for the three and six months ended February 28, 2025 and February 29, 2024, by segment:

NTIC’s joint venture operating income decreased 31.8% to $1,691,000 during the three months ended February 28, 2025, compared to joint venture operating income of $2,481,000 during the three months ended February 29, 2024. The $790,000 decrease in joint venture operating income was primarily due to a decrease in equity in income from joint ventures and fees for services provided to joint ventures, both of which were driven primarily by lower sales at most of NTIC’s joint ventures. Net sales of NTIC’s joint ventures, which are not consolidated with NTIC’s financial results, decreased 15.7% to $19,800,000 during the three months ended February 28, 2025, compared to $23,480,000 for the three months ended February 29, 2024. Year-to-date, NTIC’s joint venture operating income was $4,105,000, compared to joint venture operating income of $4,832,000 during the six months ended February 29, 2024. Net sales of NTIC’s joint ventures were $43,637,000 for the six months ended February 28, 2025, compared to $47,041,000 for the six months ended February 29, 2024.

Operating expenses, as a percent of net sales, for the second quarter of fiscal 2025 were 46.2%, compared to 41.3% for the same period last fiscal year. Year-to-date, operating expenses, as a percent of net sales, were 45.3%, compared to 41.3% for the same period last fiscal year. Higher operating expenses for the three and six months ended February 28, 2025 were primarily due to strategic investments in ZERUST® oil and gas sales infrastructure and increased personnel expenses, including new hires and benefits, and higher travel and professional fees.

NTIC recognized $1,140,000 in other income during the three and six months ended February 28, 2025 due to the receipt of a cash ERC payment. No other income was recognized during the prior year periods.

Net income attributable to NTIC for the second quarter of fiscal 2025 was $434,000, or $0.04 per diluted share, compared to net income of $1,701,000, or $0.17 per diluted share, for the same period last fiscal year. Year-to-date, net income attributable to NTIC was $995,000, or $0.10 per diluted share, compared to net income of $2,597,000, or $0.27 per diluted share, for the same period last fiscal year.

NTIC’s non-GAAP adjusted net income, as set forth in the GAAP reconciliation at the end of this release, was a loss of $300,000, or $(0.03) per diluted share, for the second quarter of fiscal 2025, compared to net income of $1,807,000, or $0.19 per diluted share, for the same quarter last fiscal year. Year-to-date, non-GAAP adjusted net income was $367,000, or $0.04 per diluted share, compared to net income of $2,808,000, or $0.29 per diluted share, for the same period last fiscal year.

NTIC had working capital of $21,416,000 as of February 28, 2025, including $5,091,000 in cash and cash equivalents and an outstanding revolving line of credit and term loan balance of $8,101,000, 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 February 28, 2025, the Company had $25,041,000 of investments in joint ventures, of which $13,025,000, or 52.0%, is cash, with the remaining balance mostly made up of other working capital.

RECONCILIATION OF GAAP TO NON-GAAP MEASURES
(UNAUDITED, IN THOUSANDS, EXCEPT SHARE AND PER SHARE AMOUNTS)

The accompanying press release contains certain non-GAAP financial measures, including adjusted net income attributable to NTIC and adjusted net 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 uses non-GAAP financial measures as supplemental measures of performance and believes these measures facilitate operating performance comparisons from period to period and company to company by factoring out potential differences caused by non-recurring, unusual or infrequent charges not related to NTIC’s regular, ongoing business. 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 income attributable to NTIC and reported net income attributable to NTIC per diluted common share to adjusted net income attributable to NTIC and adjusted net income attributable to NTIC per diluted common share, in each case, as adjusted to exclude the contribution from the receipt of an ERC payment and amortization expense.
