## Exhibit 99.1

**EXHIBIT 99.1**

**Northern Technologies International Corporation Reports Financial Results for First Quarter Fiscal 2023**

MINNEAPOLIS, Jan. 12, 2023 (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 first quarter of fiscal 2023.

First quarter fiscal 2023 financial and operating highlights include (with growth rates on a fiscal quarter year-over-year basis):

* Consolidated net sales increased 9.7% to a first quarter record of $19,953,000

* ZERUST<sup>®</sup> net sales increased 6.6% to $15,370,000

* ZERUST<sup>®</sup> Oil & Gas net sales increased 66.9% to $1,622,000

* NTIC China net sales decreased 7.7% to $3,747,000

* Natur-Tec<sup>®</sup> product net sales increased 21.6% to $4,583,000

* Joint venture operating income decreased 10.0% to $2,371,000

* Net income attributable to NTIC decreased to $502,000, or $0.05 per diluted share, compared to $4,494,000, or $0.46 per diluted share; non-GAAP adjusted net income, excluding the gain on the acquisition of the remaining ownership interest ZERUST<sup>®</sup> India and other adjustments as set forth in the reconciliation below, was $608,000, or $0.06 per diluted share, compared to $781,000, or $0.08 per diluted share

* Consolidated balance sheet as of November 30, 2022 was strong, with net cash and cash equivalents of $6,072,000

"Demand continues to be stable from new and existing customers in North America for our ZERUST<sup>®</sup> Industrial products and services, while strengthening for our Natur-Tec and ZERUST<sup>®</sup> Oil & Gas products both in the U.S. and abroad. As the world continues to reopen from COVID-19, we are building new customer relationships and enjoying strong global demand for our leading compostable plastic solutions. Additionally, the expanding adoption of our solutions within the oil and gas industry is supporting larger opportunities for our ZERUST<sup>®</sup> Oil & Gas products and technologies. Despite a more challenging operating environment across several of our ZERUST<sup>®</sup> Industrial joint ventures, we expect to achieve record Natur-Tec and Zerust Oil & Gas sales in fiscal 2023," said G. Patrick Lynch, President and Chief Executive Officer of NTIC.

"We continue to focus on controlling operating expenses, enhancing gross margins and, thereby, improving overall profitability. Consequently, we expect our annualized profitability to improve for fiscal 2023 compared to fiscal 2022," concluded Mr. Lynch.

NTIC's consolidated net sales increased 9.7% to $19,953,000 during the three months ended November 30, 2022, compared to $18,193,000 for the three months ended November 30, 2021. The year-over-year increase in consolidated net sales was primarily due to sales growth within the Company's ZERUST<sup>®</sup> Industrial, ZERUST<sup>®</sup> Oil & Gas, and Natur-Tec product categories, as a result of higher global demand, as well as targeted price increases on certain products.

The following tables set forth NTIC's net sales by product category for the three months ended November 30, 2022 and November 30, 2021, by segment:

---

| | | | | | |
|:---|:---|:---|:---|:---|:---|
|  | **Three Months Ended** | **Three Months Ended** | **Three Months Ended** | **Three Months Ended** | **Three Months Ended** |
|  | **November 30, <br>2022** | **% of Net <br>Sales** | **November 30, <br>**2021** | **% of Net <br>Sales** | **% <br>Change** |
| ZERUST<sup>®</sup>industrial net sales | $13114638 | 65.7% | $12611530 | 69.3% | 4.0% |
| ZERUST<sup>®</sup>joint venture net sales | 633466 | 3.2% | 840439 | 4.6% | -24.6% |
| ZERUST<sup>®</sup>Oil & Gas net sales | 1621897 | 8.1% | 971816 | 5.3% | 66.9% |
| &nbsp;&nbsp;&nbsp;&nbsp;Total ZERUST<sup>®</sup>net sales | $15370001 | 77.0% | $14423785 | 79.3% | 6.6% |
| Total Natur-Tec<sup>®</sup>net sales | 4582765 | 23.0% | 3769628 | 20.7% | 21.6% |
| &nbsp;&nbsp;&nbsp;&nbsp;Total net sales | $19952766 | 100.0% | $18193413 | 100.0% | 9.7% |

NTIC's joint venture operating income decreased 10.0% to $2,371,000 during the three months ended November 30, 2022, compared to joint venture operating income of $2,634,000 during the three months ended November 30, 2021. This decrease was attributable to a corresponding reduction in total net sales of the joint ventures as fees for services provided to joint ventures are primarily a function of the net sales of NTIC's joint ventures, which decreased 8.5% to $24,730,000 during the three months ended November 30, 2022, compared to $27,023,000 for the three months ended November 30, 2021.

Operating expenses, as a percent of net sales, for the first quarter of fiscal 2023 were 39.6%, compared to 38.9% for the same period last fiscal year. This slight decline in operating leverage was due to increased personnel expenses and expenses incurred during the current fiscal year period in connection with the startup of a new indirect, majority owned subsidiary, formed to assume control in Taiwan after our long-standing joint venture partner there passed away unexpectedly during the height of the pandemic last year. On a dollar basis, first quarter fiscal 2023 operating expenses were $7,895,000, compared to $7,070,000 for the same period last fiscal year.

The Company reported net income attributable to NTIC for the first quarter of fiscal 2023 of $502,000, or $0.05 per diluted share, compared to net income of $4,494,000, or $0.46 per diluted share for the same period last fiscal year. NTIC's non-GAAP adjusted net income, excluding a gain of $3,952,000 relating to the acquisition of the remaining ownership interest of ZERUST<sup>®</sup> India and other adjustments as set forth in the GAAP reconciliation at the end of this release, was $608,000, or $0.06 per diluted share, for the first quarter of fiscal 2023 compared to $781,000, or $0.08 per diluted share, for the same quarter last fiscal year.

NTIC's consolidated balance sheet remains strong, with working capital of $25,409,000 as of November 30, 2022, including $6,066,000 in cash and cash equivalents, $6,000 in available for sale securities, and outstanding revolving line of credit balance of $5,450,000, compared to $23,169,000 of working capital as of August 31, 2022, including $5,334,000 in cash and cash equivalents and $6,000 in available for sale securities, and an outstanding revolving line of credit balance of $5,900,000.

As of November 30, 2022, the Company had $20,332,000 of investments in joint ventures, of which $9,740,000, or 47.9%, is cash, with the remaining balance mostly made up of other working capital.

**NORTHERN TECHNOLOGIES INTERNATIONAL CORPORATION AND SUBSIDIARIES 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 information supplemental 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 net one-time gain related to the acquisition of the remaining 50% ownership interest of ZERUST<sup>**®**</sup> India and certain other adjustments as described below.
