<p style="font-size: 10pt; margin: 0 0 12pt"><i>Recently Issued Accounting Pronouncements</i></p>

<p style="font-size: 10pt; margin: 0">In May 2014, the Financial Accounting Standards Board (FASB) issued guidance creating Accounting
Standards Codification (ASC) Section 606, <i>Revenue from Contracts with Customers</i>, which establishes a comprehensive new model
for the recognition of revenue from contracts with customers. This model is based on the core principle that revenue should be
recognized to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which
the entity expects to be entitled in exchange for those goods or services. The Company has performed a review of the requirements
of the new guidance and has identified which of its revenue streams will be within the scope of ASC 606. The Company has applied
the five-step model of the new standard to a selection of contracts within each of its revenue streams and has compared the results
to its current accounting practices. The Company is expecting to utilize the modified retrospective transition method of adoption.
The Company is continuing to work through the remaining steps of the adoption plan to facilitate adoption effective September 1,
2018. As part of this, the Company is assessing changes that might be necessary to information technology systems, processes, and
internal controls to capture new data and address changes in financial reporting. The Company will be revising its revenue recognition
accounting policy and expanding revenue disclosures to reflect the requirements of ASC 606, which include disclosures related to
the nature, amount, timing and uncertainty of revenue and cash flows arising from contracts with customers. Additionally, qualitative
and quantitative disclosures are required about customer contracts, significant judgments and assets recognized from the costs
to obtain or fulfill a contract. Based on its assessment to date, the Company does not expect the adoption of this standard to
have a material impact on the way it recognizes revenue.</p>

<p style="font-size: 10pt; margin: 0">&nbsp;</p>

<p style="font-size: 10pt; margin: 0pt">During February 2016, the FASB issued ASU No. 2016-02, <i>Leases</i>. ASU No. 2016-02
was issued to increase transparency and comparability among organizations by recognizing all lease transactions (with terms in
excess of 12 months) on the balance sheet as a lease liability and a right-of-use asset (as defined). ASU No. 2016-02 is effective
for fiscal years beginning after December 15, 2018, including interim periods within those fiscal years, with earlier application
permitted. Upon adoption, the lessee will apply the new standard retrospectively to all periods presented or retrospectively using
a cumulative effect adjustment in the year of adoption. The guidance will be effective for the Company&#8217;s first quarter of
fiscal 2020. The Company is currently assessing the effect that ASU No. 2016-02 will have on its consolidated financial statements.</p>

<p style="font-size: 10pt; margin: 0pt">&nbsp;</p>

<p style="font-size: 10pt; margin: 0 0 10pt">In August 2016, the FASB issued ASU No. 2016-15, <i>Statement of Cash Flows, Classification
of Certain Cash Receipts and Cash Payments.</i>&nbsp;ASU No. 2016-15 eliminates the diversity in practice related to the classification
of certain cash receipts and payments for debt prepayments or extinguishment costs, the maturing of a zero-coupon bond, the settlement
of contingent liabilities arising from a business combination, proceeds from insurance settlements, distributions from certain
equity method investees and beneficial interests obtained in a financial asset securitization. ASU No. 2016-15 designates the appropriate
cash flow classification, including requirements to allocate certain components of these cash receipts and payments among operating,
investing and financing activities. The guidance is effective for fiscal years beginning after December 15, 2017. Early adoption
is permitted. The Company is currently evaluating the effects of adopting ASU No. 2016-15 on its consolidated financial statements.</p>

<p style="font-size: 10pt; margin: 0">In February 2018, the FASB issued ASU No. 2018-02, <i>Income Statement &#8211; Reporting
Comprehensive Income (Topic 220) Reclassification of Certain Tax Effects from Accumulated Other Comprehensive Income</i>, which
will allow a reclassification from accumulated other comprehensive income to retained earnings for the tax effects resulting from
the Tax Cuts and Jobs Act (Tax Reform Act) that are stranded in accumulated other comprehensive income. This standard also requires
certain disclosures about stranded tax effects. ASU No. 2018-02, however, does not change the underlying guidance that requires
that the effect of a change in tax laws or rates be included in income from continuing operations. ASU No. 2018-02 will be effective
for the Company&#8217;s fiscal year 2020, with the option for early adoption at any time prior to the effective date. It must be
applied either in the period of adoption or retrospectively to each period in which the effect of the change in the U.S. federal
corporate income tax rate in the Tax Reform Act is recognized. The Company is currently assessing the impact this new accounting
guidance will have on its consolidated financial statements.</p>

<p style="font-size: 10pt; margin: 0">&nbsp;</p>

<p style="font-size: 10pt; margin: 0">In December 2017, the Securities and Exchange Commission (SEC) issued Staff Accounting Bulletin
(SAB) No. 118 (as further clarified by FASB ASU No. 2018-05, <i>Income Taxes</i> (Topic 740): &#8220;Amendments to SEC Paragraphs
Pursuant to SEC Staff Accounting Bulletin No. 118&#8221;) to provide guidance for companies that may not have completed their accounting
for the income tax effects of the Tax Reform Act in the period of enactment, which is the period that includes December 22, 2017.
SAB No. 118 provides for a provisional one-year measurement period for entities to finalize their accounting for certain income
tax effects related to the Tax Reform Act. SAB No. 118 provides guidance where: (i) the accounting for the income tax effect of
the Tax Reform Act is complete and reported in the Tax Reform Act&#8217;s enactment period, (ii) the accounting for the income
tax effect of the Tax Reform Act is incomplete and reported as provisional amounts based on reasonable estimates (to the extent
determinable) subject to adjustments during a limited measurement period until complete, and (iii) accounting for the income tax
effect of the Tax Reform Act is not reasonably estimable (no related provisional amounts are reported in the enactment period)
and entities would continue to apply accounting based on tax law provisions in effect prior to the Tax Reform Act enactment until
provisional amounts are reasonably estimable. SAB No. 118 requires disclosure of the reasons for incomplete accounting additional
information or analysis needed, among other relevant information (see Note 15 - Income Taxes).</p>

<p style="font-size: 10pt; margin: 0 0 12pt">The Company has a revolving line of credit with PNC Bank, National Association (PNC
Bank) of $3,000,000. No amounts were outstanding under the line of credit as of both May 31, 2018 and August 31, 2017. At the option
of the Company, outstanding advances under the line of credit bear interest at either (a) an annual rate based on LIBOR plus 2.15%
for the applicable LIBOR interest period selected by the Company or (b) at the rate publicly announced by PNC Bank from time to
time as its prime rate.</p>

<p style="font-size: 10pt; margin: 0 0 12pt">The line of credit is governed under a loan agreement. The loan agreement contains
standard covenants, including affirmative financial covenants, such as the maintenance of a minimum fixed charge coverage ratio,
and negative covenants, which, among other things, limit the incurrence of additional indebtedness, loans and equity investments,
disposition of assets, mergers and consolidations and other matters customarily restricted in such agreements. Under the loan agreement,
the Company is subject to a minimum fixed charge coverage ratio of 1.10:1.00. As of May 31, 2018, the Company was in compliance
with all debt covenants.</p>

<p style="font-size: 10pt; margin: 0 0 12pt">The revolving credit facility allows the Company to request that PNC Bank issue letters
of credit up to $1,200,000. The Company did not have any letters of credit reserved against the available letters of credit balance
as of May 31, 2018 and August 31, 2017 with PNC Bank. The availability of advances under the line of credit will be reduced by
the face amount of any letter of credit issued and outstanding (whether or not drawn) under the revolving credit facility.&nbsp;</p>

<p style="font-size: 10pt; margin: 0pt">On January 5, 2018, the Company and PNC Bank extended the maturity date of the line

<p style="font-size: 10pt; margin: 0 0 12pt">During the nine months ended May 31, 2018, stock options to purchase an aggregate
of 4,410 shares of common stock were exercised at a weighted average exercise price of $11.59 per share.</p>

<p style="font-size: 10pt; margin: 0 0 12pt">The Company granted stock options under the Northern Technologies International Corporation
Amended and Restated 2007 Stock Incentive Plan (2007 Plan) to purchase an aggregate of 47,252 shares of its common stock to various
employees and directors during the nine months ended May 31, 2018. The weighted average per share exercise price of the stock options
is $18.35, which was equal to the fair market value of the Company&#8217;s common stock on the date of grant.</p>

<p style="font-size: 10pt; margin: 0 0 12pt">The Company issued 891 and 3,029 shares of common stock on September 1, 2017 and 2016,

985 and 1098 shares of common stock on March 1, 2018 and 2017, respectively, under the ESPP.</p>

<p style="font-size: 10pt; margin: 0 0 12pt">The Company held its 2018 Annual Meeting of Stockholders (2018 Annual Meeting) on
January 12, 2018. At the 2018 Annual Meeting, a proposal to approve an amendment to the Company&#8217;s Restated Certificate of
Incorporation to increase the Company&#8217;s authorized shares of common stock from 10,000,000 to 15,000,000 (Share Increase Amendment)
was approved by the Company&#8217;s stockholders by the required vote. The Share Increase Amendment was filed with the Office of
the Secretary of State of the State of Delaware on January 16, 2018 and it became effective the same day. In determining that the
Share Increase Amendment was approved by the required vote, votes cast by brokers, banks or other nominees without instruction
from the beneficial owners of certain of our outstanding shares were counted in favor of the proposal in accordance with the rules
of the New York Stock Exchange that govern how brokers may cast such votes. Because a disclosure in the definitive proxy statement
for the 2018 Annual Meeting, which was filed on Schedule 14A with the Securities and Exchange Commission (SEC) on November 27,
2017 (2018 Proxy Statement), anticipated that brokers would not have discretion to vote for the proposal to approve the Share Increase
Amendment, a question has been raised as to the validity of the vote taken on the proposal to approve the Share Increase Amendment.
The Company believes that the Share Increase Amendment was properly approved and is effective. However, because the description

<p style="font-size: 10pt; margin: 0 0 12pt">On August 31, 2017, the Compensation Committee of the Board of Directors of the Company
approved the material terms of an annual bonus plan for the Company&#8217;s executive officers as well as certain officers and
employees for the fiscal year ending August 31, 2018. For fiscal 2018 as in past years, the total amount available under the bonus
plan for all plan participants, including executive officers, is dependent upon the Company&#8217;s earnings before interest, taxes
and other income (EBITOI), as adjusted to take into account amounts to be paid under the bonus plan and certain other adjustments
(Adjusted EBITOI). Each plan participant&#8217;s percentage of the overall bonus pool is based upon the number of plan participants,
the individual&#8217;s annual base salary and the individual&#8217;s position and level of responsibility within the Company. In
the case of each of the Company&#8217;s executive officer participants, 75% of the amount of their individual bonus payout will
be determined based upon the Company&#8217;s actual Adjusted EBITOI for fiscal 2018 compared to a pre-established target EBITOI
for fiscal 2018 and 25% of the payout will be determined based upon such executive officer&#8217;s achievement of certain pre-established
individual performance objectives. The payment of bonuses under the plan are discretionary and may be paid to executive officer
participants in both cash and shares of the Company&#8217;s common stock, the exact amount and percentages will be determined by
the Company&#8217;s Board of Directors, upon recommendation of the Compensation Committee, after the completion of the Company&#8217;s
consolidated financial statements for fiscal 2018. There was $1,380,000 accrued for management bonuses for the nine months ended
May 31, 2018 compared to $600,000 accrued for management bonuses for the nine months ended May 31, 2017.</p>

<p style="font-size: 10pt; margin: 0 0 12pt">Three joint ventures (consisting of the Company&#8217;s joint ventures in South Korea,
India and United States) accounted for 51.8% of the Company&#8217;s trade joint venture receivables at May 31, 2018, and three
joint ventures (consisting of the Company&#8217;s joint ventures in South Korea, Thailand and India) accounted for 60.7% of the
Company&#8217;s trade joint venture receivables at August 31, 2017.</p>

<p style="font-size: 10pt; margin: 0pt">From time to time, the Company is subject to various other claims and legal actions
in the ordinary course of its business. The Company records a liability in its consolidated financial statements for costs related
to claims, including future legal costs, settlements and judgments, where the Company has assessed that a loss is probable and
an amount could be reasonably estimated. If the reasonable estimate of a probable loss is a range, the Company records the most
probable estimate of the loss or the minimum amount when no amount within the range is a better estimate than any other amount.
The Company discloses a contingent liability even if the liability is not probable or the amount is not estimable, or both, if
there is a reasonable possibility that material loss may have been incurred. In the opinion of management, as of May 31, 2018,
the amount of liability, if any, with respect to these matters, individually or in the aggregate, will not materially affect the
Company&#8217;s consolidated results of operations, financial position or cash flows.</p></div><p style="font-size: 10pt; margin: 0pt"></p>

<p style="font-size: 10pt; margin: 0pt">On December 22, 2017, the U.S. government enacted comprehensive tax legislation commonly
referred to as the Tax Cuts and Jobs Act, or Tax Reform Act. The Tax Reform Act makes broad and complex changes to the U.S. tax
code that will affect the Company&#8217;s fiscal year ending August 31 2018, including, but not limited to, reducing the U.S. federal
corporate tax rate from 35% to 21% effective January 1, 2018, generally eliminating U.S. federal income taxes on dividends received
from foreign subsidiaries and joint ventures after December 31, 2017, and imposing a one-time deemed repatriation tax on certain
unremitted earnings of foreign subsidiaries and joint ventures. The Company will be subject to a blended U.S. federal tax rate
of 25.7% for the fiscal year ending August 31, 2018 as a result of the reduction of the U.S. federal corporate tax rate from 35%
to 21% effective January 1, 2018.</p>

<p style="font-size: 10pt; margin: 0pt">&nbsp;</p>

<p style="font-size: 10pt; margin: 0 0 12pt">The Company recognized the income tax effects of the Tax Reform Act in its 2018 interim
consolidated financial statements in accordance with SAB No. 118, which provides SEC staff guidance for the application of ASC
Topic 740, <i>Income Taxes</i>, in the reporting period in which the Tax Reform Act was signed into law. As such, the Company&#8217;s
financial results reflect the income tax effects of the Tax Reform Act for which the accounting under ASC Topic 740 is complete
and provisional amounts for those specific income tax effects of the Tax Reform Act for which the accounting under ASC Topic 740
is incomplete but a reasonable estimate could be determined.</p>

<p style="font-size: 10pt; margin: 0 0 12pt">The Company recorded income tax expense during the three and nine months ended May
31, 2018 of $181,683 and $1,128,583, respectively, compared to $237,801 and $480,423 for the three and nine months ended May 31,
2017.</p>

<p style="font-size: 10pt; margin: 0 0 12pt">The Company measures deferred tax assets and liabilities using enacted tax rates that
will apply in the years in which the temporary differences are expected to be recovered or paid. Accordingly, the Company&#8217;s
deferred tax assets and liabilities were re-measured to reflect the reduction in the U.S. corporate income tax rate from 35% to
21% effective January 1, 2018, resulting in an increase of $700,000 in income tax expense for the nine months ended May 31, 2018
and a corresponding decrease of $700,000 in net deferred tax assets as of May 31, 2018 compared to August 31, 2017. The $700,000
income tax expense and corresponding decrease in net deferred tax assets represents a provisional estimate based on the Company&#8217;s
current interpretation of the Tax Reform Act and may change as the Company receives additional clarification and implementation
guidance. No changes were recorded during the three months ended May 31, 2018.</p>

<p style="font-size: 10pt; margin: 0 0 12pt">The one-time deemed repatriation tax is applicable to the unremitted earnings of the
Company&#8217;s foreign subsidiaries and joint ventures. The Company calculated deemed repatriation tax of $489,000, which the
Company expects to fully offset with foreign tax credit carryforwards for which the Company has not previously recognized a tax
benefit. As a result, the transition tax resulted in zero increase in income tax expense and income taxes payable for the nine
months ended May 31, 2018. The $489,000 transition tax on deemed repatriation of unremitted foreign earnings represents a provisional
estimate and is subject to adjustment during the measurement period of up to one year following the December 2017 enactment date
of the Tax Reform Act, as provided by recent SEC guidance. No adjustments were recorded during the three months ended May 31, 2018.</p>

<p style="font-size: 10pt; margin: 0pt">The Company continues to analyze the impact of other provisions of the Tax Reform
Act on its financial statements and operations, including the impact of the global intangible low-taxed income (GILTI) rules, and
the impact of the Tax Reform Act on the Company&#8217;s indefinite reinvestment assertion with respect to the undistributed earnings
of certain foreign subsidiaries and joint ventures. Any additional impacts from the enactment of the Tax Reform Act will be recorded
as they are identified during the measurement period as provided for in accordance with SAB No. 118.</p></div><p style="font-size: 10pt; margin: 0pt"></p>

<p style="font-size: 10pt; margin: 0 0 12pt"><b>Business Overview</b></p>

<p style="font-size: 10pt; margin: 0 0 12pt">NTIC develops and markets proprietary environmentally beneficial products and services
in over 60 countries either directly or via a network of subsidiaries, joint ventures, independent distributors and agents. NTIC&#8217;s
primary business is corrosion prevention marketed mainly under the ZERUST&#174; brand. NTIC has been selling its proprietary ZERUST&#174;
products and services to the automotive, electronics, electrical, mechanical, military and retail consumer markets for over 40
years, and in recent years, has targeted and expanded into the oil and gas industry. NTIC also markets and sells a portfolio of
biobased and certified compostable (fully biodegradable) polymer resin compounds and finished products under the Natur-Tec&#174;
brand. These products are intended to reduce NTIC&#8217;s customers&#8217; carbon footprint and provide environmentally sound waste
disposal options.</p>

<p style="font-size: 10pt; margin: 0 0 12pt">NTIC&#8217;s ZERUST<sup>&#174;</sup> rust and corrosion inhibiting products include
plastic and paper packaging, liquids, coatings, rust removers, cleaners, and diffusers as well as engineered solutions designed
specifically for the oil and gas industry. NTIC also offers worldwide on-site technical consulting for rust and corrosion prevention
issues. NTIC&#8217;s technical service consultants work directly with the end users of NTIC&#8217;s ZERUST<sup>&#174;</sup> rust
and corrosion inhibiting products to analyze their specific needs and develop systems to meet their performance requirements. In
North America, NTIC sells its ZERUST<sup>&#174;</sup> corrosion prevention solutions through a network of independent distributors
and agents supported by a direct sales force. Internationally, NTIC sells its ZERUST<sup>&#174;</sup> corrosion prevention solutions
through its wholly-owned subsidiary in China, NTIC (Shanghai) Co., Ltd. (NTIC China), its majority-owned joint venture holding
company for NTIC&#8217;s joint venture investments in the Association of Southeast Asian Nations (ASEAN) region, NTI Asean LLC
(NTI Asean), its majority-owned subsidiary in Brazil, Zerust Preven&#231;&#227;o de Corros&#227;o S.A. (Zerust Brazil), and
its wholly-owned subsidiary in Mexico, ZERUST-EXCOR MEXICO, S. de R.L. de C.V (Zerust Mexico), and joint venture arrangements in
North America, Europe and Asia. NTIC also sells products directly to its joint venture partners through its wholly-owned subsidiary
in Germany, NTIC Europe GmbH (NTI Europe).</p>

<p style="font-size: 10pt; margin: 0 0 12pt">One of NTIC&#8217;s strategic initiatives is to expand into and penetrate other markets
for its ZERUST<sup>&#174;</sup> corrosion prevention technologies. Consequently, for the past several years, NTIC has focused significant
sales and marketing efforts on the oil and gas industry, as the infrastructure that supports that industry is typically constructed
using metals that are highly susceptible to corrosion. NTIC believes that its ZERUST<sup>&#174;</sup> corrosion prevention solutions
will minimize maintenance downtime on critical oil and gas industry infrastructure, extend the life of such infrastructure and
reduce the risk of environmental pollution due to corrosion leaks.</p>

<p style="font-size: 10pt; margin: 0pt">NTIC markets and sells its ZERUST&#174; rust and corrosion prevention solutions to
customers in the oil and gas industry across several countries either directly, through its subsidiaries or through its joint venture
partners and other strategic partners. The sale of ZERUST&#174; corrosion prevention solutions to customers in the oil and gas industry
typically involves long sales cycles, often including multi-year trial periods with each customer and a slow integration process
thereafter.</p>

<p style="font-size: 10pt; margin: 0 0 12pt">Natur-Tec<sup>&#174;</sup> biobased and compostable plastics are manufactured using
NTIC&#8217;s patented and/or proprietary technologies and are intended to replace conventional petroleum-based plastics. The Natur-Tec<sup>&#174;</sup>
biopolymer resin compound portfolio includes formulations that have been optimized for a variety of applications including blown-film
extrusion, extrusion coating, injection molding, and engineered plastics. These resin compounds are certified to be fully biodegradable
in a composting environment and are currently being used to produce finished products including can liners, shopping and grocery
bags, lawn and leaf bags, pet waste collection bags, cutlery and coated paper products. In North America, NTIC markets its Natur-Tec<sup>&#174;</sup>
resin compounds and finished products primarily through a network of regional and national distributors as well as independent
agents. NTIC continues to see significant opportunities for finished bioplastic products and, therefore, continues to strengthen
and expand its North American distribution network for finished Natur-Tec<sup>&#174;</sup> bioplastic products. Internationally,
NTIC sells its Natur-Tec<sup>&#174;</sup> resin compounds and finished products both directly and through its majority-owned subsidiary
in India, Natur-Tec India Private Limited (Natur-Tec India), and through distributors and certain joint ventures.</p>

<p style="font-size: 10pt; margin: 0 0 12pt">The results of these subsidiaries are fully consolidated in NTIC&#8217;s consolidated
financial statements.</p>

<p style="font-size: 10pt; margin: 0 0 12pt">NTIC participates in 20 active joint venture arrangements in North America, Europe
and Asia. Each of these joint ventures generally manufactures and markets products in the geographic territory to which it is assigned.
While most of NTIC&#8217;s joint ventures exclusively sell rust and corrosion inhibiting products, some of the joint ventures also
sell NTIC&#8217;s Natur-Tec&#174; resin compounds. NTIC has historically funded its investments in joint ventures with cash generated
from operations.</p>

<p style="font-size: 10pt; margin: 0 0 12pt">NTIC&#8217;s receipt of funds from its joint ventures is dependent upon fees for services
that NTIC provides to its joint ventures, based primarily on the net sales of the individual joint ventures, and NTIC&#8217;s receipt
of dividend distributions from the joint ventures. The fees for services provided to joint ventures are determined based on either
a flat fee or a percentage of sales depending on local laws and tax regulations. With respect to NTIC&#8217;s joint venture in
Germany (EXCOR), NTIC recognizes an agreed upon quarterly fee for such services. NTIC recognizes equity income from each joint
venture based on the overall profitability of the joint venture. Such profitability is subject to variability from quarter to quarter
which, in turn, subjects NTIC&#8217;s earnings to variability from quarter to quarter. The profits of each joint venture are shared
by the respective joint venture owners in accordance with their respective ownership percentages. NTIC typically directly or indirectly
owns 50% or less of each of its joint venture entities and thus does not control the decisions of these entities regarding whether
to pay dividends and, if paid, how much they should be in a given year. The payment of a dividend by an entity is determined by
a joint vote of the owners and is not at the sole discretion of NTIC.</p>

<p style="font-size: 10pt; margin: 0pt">NTIC accounts for the investments and financial results of its joint ventures in its
financial statements utilizing the equity method of accounting.</p>

statements and in this section of this report.</p>

<p style="font-size: 10pt; margin: 0 0 12pt"><b>Financial Overview </b></p>

<p style="font-size: 10pt; margin: 0 0 12pt">NTIC&#8217;s management, including its chief executive officer who is NTIC&#8217;s
chief operating decision maker, reports and manages NTIC&#8217;s operations in two reportable business segments based on products
sold, customer base and distribution center: ZERUST&#174; products and services and Natur-Tec&#174; products.</p>

<p style="font-size: 10pt; margin: 0 0 12pt">NTIC&#8217;s consolidated net sales increased 26.4% and 28.0% during the three and
nine months ended May 31, 2018, respectively, compared to the three and nine months ended May 31, 2017. These increases were primarily
a result of increased demand of ZERUST<sup>&#174;</sup> rust and corrosion inhibiting packaging products and services and the addition
of new customers in North America and China and an increase in sales of Natur-Tec&#174; products.</p>

<p style="font-size: 10pt; margin: 0 0 12pt">During the three and nine months ended May 31, 2018, 80.3% and 82.1% of NTIC&#8217;s
consolidated net sales, respectively, were derived from sales of ZERUST&#174; products and services, which increased 24.1% and 27.1%
to $10,382,884 and $30,102,080 during the three and nine months ended May 31, 2018, respectively, compared to $8,368,487 and $23,681,192
during the three and nine months ended May 31, 2017, respectively. These increases were due to increased demand of ZERUST<sup>&#174;</sup>
rust and corrosion inhibiting packaging products and services and the addition of new customers in North America and China. NTIC
has focused its sales efforts of ZERUST&#174; products and services by strategically targeting customers with specific corrosion
issues in new market areas, including the oil and gas industry and other industrial sectors that offer sizable growth opportunities.
NTIC&#8217;s consolidated net sales for the nine months ended May 31, 2018 included $1,418,573 of sales made to customers in the
oil and gas industry compared to $1,287,789 for the nine months ended May 31, 2017. Overall demand for ZERUST&#174; products and
services depends heavily on the overall health of the markets in which NTIC sells its products, including the automotive, oil and
gas, agriculture, and mining markets in particular.</p>

<p style="font-size: 10pt; margin: 0 0 12pt">During the three and nine months ended May 31, 2018, 19.7% and 17.9%, of NTIC&#8217;s
consolidated net sales, respectively, were derived from sales of Natur-Tec&#174; products compared to 18.1% and 17.4% during the
three and nine months ended May 31, 2017, respectively. Net sales of Natur-Tec&#174; products increased 37.0% and 31.9% during the
three and nine months ended May 31, 2018, respectively, compared to the three and nine months ended May 31, 2017, primarily due
to an increase in finished product sales in North America and finished product sales at NTIC&#8217;s majority owned subsidiary
in India, Natur-Tec India Private Limited (Natur-Tec India).</p>

<p style="font-size: 10pt; margin: 0 0 12pt">Cost of goods sold as a percentage of net sales increased slightly to 66.5% during
the three months ended May 31, 2018 compared to 66.3% during the three months ended May 31, 2017 and decreased slightly to 66.8%
during the nine months ended May 31, 2018 compared to 67.2% during the prior fiscal year period, primarily due to product mix and
the different gross profits realized on different products.</p>

<p style="font-size: 10pt; margin: 0pt">NTIC&#8217;s equity in income from joint ventures increased 33.2% and 33.4% to $2,246,066
and $5,793,391, respectively, during the three and nine months ended May 31, 2018 compared to $1,686,016 and $4,343,159 during
the three and nine months ended May 31, 2017, respectively. These increases were primarily due to corresponding increases in net
sales at the joint ventures, which increased 21.4% and 23.4% to $31,480,885 and $90,200,146 during the three and nine months ended
May 31, 2018, respectively, compared to $25,935,169 and $73,098,215 for the three and nine months ended May 31, 2017, respectively,
as well as a strengthened Euro and other currencies compared to the U.S. Dollar. The increases in net sales of NTIC&#8217;s joint
ventures were due primarily to higher sales from existing customers for new and existing products as a result of increased demand.</p>

<p style="font-size: 10pt; margin: 0 0 12pt">NTIC&#8217;s total operating expenses increased 16.2% and 12.1% to $5,632,826 and
$16,622,849 during the three and nine months ended May 31, 2018, respectively, compared to $4,847,144 and $14,831,577 for the three
and nine months ended May 31, 2017. These increases were primarily due to an increase in NTIC&#8217;s personnel expenses, including
an increase in the management bonus accrual of $780,000. Operating expenses, as a percent of net sales, for the three months ended
May 31, 2018 were 43.6%, compared to 47.4% for the same period last fiscal year and for the nine months ended May 31, 2018 were
45.3%, compared to 51.7% for the same period last fiscal year. These reductions in operating expenses, as a percent of net sales
were primarily due to significantly higher net sales, partially offset by higher operating expenses.</p>

<p style="font-size: 10pt; margin: 0 0 12pt">NTIC spent $860,347 and $2,581,824 during the three and nine months ended May 31,
2018 compared to $733,651 and $2,118,210 during the three and nine months ended May 31, 2017, respectively, in connection with
its research and development activities. NTIC anticipates that it will spend a total of between $3,200,000 and $3,600,000 in fiscal
2018 on research and development activities.</p>

<p style="font-size: 10pt; margin: 0 0 12pt">Net income attributable to NTIC increased to $2,142,752, or $0.46 per diluted common
share, for the three months ended May 31, 2018 compared to $1,352,416, or $0.30 per diluted common share, for the three months
ended May 31, 2017, an increase of $790,336 or $0.16 per diluted share. Net income attributable to NTIC increased 123.7%, to $4,559,225,
or $0.98 per diluted common share, for the nine months ended May 31, 2018 compared to $2,039,021, or $0.45 per diluted common share,
for the nine months ended May 31, 2017, an increase of $2,520,204 or $0.53 per diluted share. These increases were primarily the
result of the increases in net sales and corresponding gross profit, as well as the increases in income from joint venture operations,
partially offset by the increase in operating expenses, as previously described. The increase for the nine-month comparison was
partially offset by the significant impact of the $700,000 one-time provisional adjustment related to the Tax Cuts and Jobs Act
(Tax Reform Act), as described in more detail below.</p>

<p style="font-size: 10pt; margin: 0 0 12pt">NTIC anticipates that its quarterly net income will continue to remain subject to
significant volatility primarily due to the financial performance of its subsidiaries and joint ventures and sales of its ZERUST&#174;
products and services into the oil and gas industry and Natur-Tec&#174; bioplastics products, which sales fluctuate more on a quarterly
basis than the traditional ZERUST&#174; business. NTIC also anticipates that its operating results during the next few quarters
will remain volatile primarily as a result of the changes in its Chinese operations.</p>

<p style="font-size: 10pt; margin: 0 0 12pt">NTIC&#8217;s working capital, as defined as current assets less current liabilities,
was $22,812,170 at May 31, 2018, including $4,610,325 in cash and cash equivalents and $3,282,915 in available for sale securities,
compared to $21,173,001 at August 31, 2017, including $6,360,201 in cash and cash equivalents and $3,766,984 in available for sale
securities.</p>

$12,923,837 and $36,680,850 during the three and nine months ended May 31, 2018, respectively, compared to the three and nine months
ended May 31, 2017. NTIC&#8217;s consolidated net sales to unaffiliated customers excluding NTIC&#8217;s joint ventures increased

<p style="font-size: 10pt; margin: 0pt">During the three and nine months ended May 31, 2018, 80.3% and 82.1% of NTIC&#8217;s
consolidated net sales, respectively, were derived from sales of ZERUST<sup>&#174;</sup> products and services, which increased
24.1% and 27.1% to $10,382,884 and $30,102,080 during the three and nine months ended May 31, 2018, respectively, compared to $8,368,487
and $23,681,192 during the three and nine months ended May 31, 2017, respectively. These increases were due to increased demand
of ZERUST<sup>&#174;</sup> industrial products and services and the addition of new customers in North America and China and increased
demand of ZERUST&#174; oil and gas products and services. NTIC has strategically focused its sales efforts for ZERUST<sup>&#174;</sup>
products and services on customers with sizeable corrosion problems in industry sectors that offer sizable growth opportunities,
including the oil and gas sector. Overall demand for ZERUST<sup>&#174;</sup> products and services depends heavily on the overall
health of the market segments to which NTIC sells its products, including the automotive, oil and gas, agriculture, and mining
markets in particular.</p>

<p style="font-size: 10pt; margin: 0">Demand for ZERUST&#174; oil and gas products around the world depends primarily on market
acceptance and the reach of NTIC&#8217;s distribution network. Because of the typical size of individual orders and overall size
of NTIC&#8217;s net sales derived from sales of oil and gas products, the timing of one or more orders can materially affect NTIC&#8217;s
quarterly sales compared to prior fiscal year quarters. NTIC anticipates that its sales of ZERUST&#174; products and services into
the oil and gas industry will continue to remain volatile from quarter to quarter as sales are recognized due to the average order
size and the timing of sales, as well as oil prices.</p>

<p style="font-size: 10pt; margin: 0">&nbsp;</p>

<p style="font-size: 10pt; margin: 0">During the three and nine months ended May 31, 2018, 19.7% and 17.9% of NTIC&#8217;s consolidated
net sales, respectively, were derived from sales of Natur-Tec&#174; products, which increased 37.0% and 31.9% to $2,540,953 and
$6,578,770 during the three and nine months ended May 31, 2018, respectively, compared to the three and nine months ended May 31,
2017. These increases were primarily due to an increase in finished product sales in North America and finished product sales at
NTIC&#8217;s majority-owned subsidiary in India, Natur-Tec India Private Limited (Natur-Tec India).</p>

<p style="font-size: 10pt; margin: 0">&nbsp;</p>

<p style="font-size: 10pt; margin: 0 0 12pt"><i>Cost of Goods Sold</i>. Cost of goods sold increased 26.8% and 27.2% for the three
and nine months ended May 31, 2018, respectively, compared to the three and nine months ended May 31, 2017. These increases were
primarily a result of the corresponding increased sales levels. Cost of goods sold as a percentage of net sales increased slightly
to 66.5% during the three months ended May 31, 2018 compared to 66.3% during the three months ended May 31, 2017 and decreased
slightly to 66.8% during the nine months ended May 31, 2018 compared to 67.2% during the nine months ended May 31, 2017 primarily
due to product mix and the different gross profits realized on different products.</p>

<p style="font-size: 10pt; margin: 0pt"><i>Equity in Income from Joint Ventures.</i> NTIC&#8217;s equity in income from joint
ventures increased 33.2% and 33.4% to $2,246,066 and $5,793,391 during the three and nine months ended May 31, 2018, respectively,
compared to $1,686,016 and $4,343,159 during the three and nine months ended May 31, 2017, respectively. These increases were primarily
a result of improved profitability at the joint ventures. Of the total equity in income from joint ventures, NTIC had equity in
income from joint ventures of $4,138,814 attributable to EXCOR during the nine months ended May 31, 2018 compared to $3,089,935

to $1,442,048 and $3,941,667 during the three and nine months ended May 31, 2017, respectively, representing increases of 4.6%
and 17.3%, respectively. Fee income for services provided to joint ventures is traditionally a function of the sales made by NTIC&#8217;s
joint ventures. Total net sales of NTIC&#8217;s joint ventures increased to $31,480,885 and $90,200,146 during the three and nine
months ended May 31, 2018, respectively, compared to $25,935,169 and $73,098,215 during the three and nine months ended May 31,
2017, respectively, representing increases of $5,545,716 and $17,101,931, respectively. Net sales of NTIC&#8217;s joint ventures
are not included in NTIC&#8217;s consolidated financial statements. Of the total fee income for services provided to joint ventures,
fees of $680,939 were attributable to EXCOR during the nine months ended May 31, 2018 compared to $614,766 attributable to EXCOR
during the nine months ended May 31, 2017.</p>

<p style="font-size: 10pt; margin: 0">&nbsp;</p>

<p style="font-size: 10pt; margin: 0 0 12pt"><i>Selling Expenses</i>. NTIC&#8217;s selling expenses increased 14.6% and 19.5% for
the three and nine months ended May 31, 2018, respectively, compared to the same respective periods in fiscal 2017 due primarily
to increases in operating expenses associated with ZERUST&#174; sales efforts, consisting primarily of selling and personnel expense.
Selling expenses as a percentage of net sales decreased to 21.5% and 21.9% for the three and nine months ended May 31, 2018, respectively,
from 23.8% and 23.4% and during the three and nine months ended May 31, 2017, respectively, primarily due to the significant increase
in net sales, partially offset by the increase in selling expenses, as previously described.</p>

<p style="font-size: 10pt; margin: 0 0 12pt"><i>General and Administrative Expenses</i>. NTIC&#8217;s general and administrative
expenses increased 18.1% and 0.3% for the three and nine months ended May 31, 2018, respectively, compared to the same respective
periods in fiscal 2017. The increase in expenses during the three-month comparison was primarily due to an increase in compensation
expense and an increase in operating expenses at NTIC China. As a percentage of net sales, general and administrative expenses
decreased to 15.4% and 16.4% for the three and nine months ended May 31, 2018, respectively, from 16.5% and 20.9% for the same
respective periods in fiscal 2017, respectively. These decreases were due primarily to the significant increase in net sales, partially
offset by the increase in general and administrative expenses, as previously described.</p>

<p style="font-size: 10pt; margin: 0 0 12pt"><i>Research and Development Expenses</i>. NTIC&#8217;s research and development expenses
increased 17.3% and 21.9% for the three and nine months ended May 31, 2018, respectively, compared to the same respective period
in fiscal 2017 due primarily to increased research and development activities during the current fiscal year periods.</p>

<p style="font-size: 10pt; margin: 0 0 12pt"><i>Interest Income</i>. NTIC&#8217;s interest income increased to $35,630 and $84,569
during the three and nine months ended May 31, 2018, respectively, compared to $10,996 and $19,075 during the three and nine months
ended May 31, 2017, respectively, due to increased levels of invested cash.</p>

<p style="font-size: 10pt; margin: 0 0 12pt"><i>Interest Expense</i>. NTIC&#8217;s interest expense decreased to $3,139 and $14,007
during the three and nine months ended May 31, 2018, respectively, compared to $7,409 and $15,502 during the three and nine months
ended May 31, 2017, respectively.</p>

<p style="font-size: 10pt; margin: 0 0 12pt"><i>Income Before Income Tax Expense</i>. NTIC incurred income before income tax expense
equal to $2,485,702 and $6,052,814 for the three and nine months ended May 31, 2018, respectively, compared to $1,733,525 and $2,867,814
for the three and nine months ended May 31, 2017, respectively.</p>

<p style="font-size: 10pt; margin: 0pt"><i>Income Tax Expense</i>. Income tax expense was $181,683 and $1,128,583 for the
three and nine months ended May 31, 2018, respectively, compared to income tax expense of $237,801 and $480,423 during the three
and nine months ended May 31, 2017, respectively. Income tax expense is calculated based on management&#8217;s estimate of NTIC&#8217;s
annual effective income tax rate. The increase for the nine-month comparison was primarily due to one-time provisional adjustments
related to the Tax Reform Act. The Tax Reform Act, among other things, reduced the U.S. federal corporate tax rate from 35% to
21% effective January 1, 2018, generally eliminated U.S. federal income taxes on dividends received from foreign subsidiaries and
joint ventures after December 31, 2017, and imposed a one-time deemed repatriation tax on certain unremitted earnings of foreign
subsidiaries and joint ventures. As a result of the change in the tax law, a one-time non-cash tax provisional charge of $700,000
related to the re-measurement of deferred tax assets and liabilities was recorded in the nine months ended May 31, 2018. The impact
of this non-cash tax charge increased NTIC&#8217;s effective rate by approximately 30.3% for the nine months ended May 31, 2018.
The $700,000 income tax expense and corresponding decrease in net deferred tax assets represents a provisional estimate based on
NTIC&#8217;s current interpretation of the Tax Reform Act and may change as NTIC receives additional clarification and implementation
guidance. NTIC continues to analyze the impact of other provisions of the Tax Reform Act on its financial statements and operations,
including the impact of the global intangible low-taxed income (GILTI) rules, and the impact of the Tax Reform Act on NTIC&#8217;s
indefinite reinvestment assertion with respect to the undistributed earnings of certain foreign subsidiaries and joint ventures.
Any additional impacts from the enactment of the Tax Reform Act will be recorded as they are identified during the measurement
period as provided for in accordance with SAB No. 118. No changes or adjustments were made during the three months ended May 31,
2018.</p>

<p style="font-size: 10pt; margin: 0 0 12pt"><i>Net Income Attributable to NTIC</i>. Net income attributable to NTIC increased
to $2,140,752, or $0.46, per diluted common share, for the three months ended May 31, 2018 compared to $1,352,416, or $0.30, per
diluted common share, for the three months ended May 31, 2017, an increase of $790,336 or $0.16 per diluted share. Net income attributable
to NTIC increased to $4,557,225, or $0.98 per diluted common share, for the nine months ended May 31, 2018 compared to $2,037,021,
or $0.45 per diluted common share, for the nine months ended May 31, 2017, an increase of $2,522,204 or $0.53 per diluted share.
These increases were primarily the result of the increases in net sales and corresponding gross profit, as well as the increases
in income from joint venture operations, partially offset by the increase in operating expenses. The increase for the nine-month
comparison was partially offset by the significant impact of the $700,000 one-time provisional adjustment related to the Tax Reform
Act. As previously mentioned, the impact from the enactment of the Tax Reform Act was driven by the provisional re-measurement
of deferred tax assets and liabilities, which resulted in a non-cash discrete tax charge of $700,000 during the nine months ended
May 31, 2018.</p>

<p style="font-size: 10pt; margin: 0 0 12pt"><i>Other Comprehensive Income - Foreign Currency Translations Adjustment. </i>The
changes in the foreign currency translations adjustment was due to the fluctuation of the U.S. dollar compared to the Euro and
other foreign currencies during the three and nine months ended May 31, 2018 compared to the same period in fiscal 2017.</p>

<p style="font-size: 10pt; margin: 0 0 12pt"><b>Liquidity and Capital Resources</b></p>

<p style="font-size: 10pt; margin: 0 0 12pt"><i>Sources of Cash and Working Capital</i>. As of May 31, 2018, NTIC&#8217;s working
capital was $22,812,170, including $4,610,325 in cash and cash equivalents and $3,282,915 in available for sale securities, compared
to $21,173,001 at August 31, 2017, including $6,360,201 in cash and cash equivalents and $3,766,984 in available for sale securities.</p>

<p style="font-size: 10pt; margin: 0 0 12pt">As of May 31, 2018, NTIC had a revolving line of credit with PNC Bank of $3,000,000,
with no amounts outstanding. The line of credit is evidenced by an amended and restated committed line of credit note in the principal
amount of up to $3,000,000. The line of credit has a $1,200,000 standby letter of credit sub-facility, with any standby letters
of credit issued thereunder being at the sole discretion of PNC Bank. Any lines of credit issued by PNC Bank would decrease the
availability under the revolving line of credit. The line of credit is subject to standard covenants, including affirmative financial
covenants, such as the maintenance of a minimum fixed charge coverage ratio, and negative covenants, which, among other things,
limit the incurrence of additional indebtedness, loans and equity investments, disposition of assets, mergers and consolidations
and other matters customarily restricted in such agreements. Under the loan agreement, NTIC is subject to a minimum fixed charge
coverage ratio of 1.10:1.00. As of May 31, 2018, NTIC was in compliance with all debt covenants.</p>

<p style="font-size: 10pt; margin: 0pt">On January 5, 2018, NTIC and PNC Bank extended the maturity date of the line of credit
from January 7, 2018 to January 7, 2019. All other terms of the line of credit and the loan agreement and other documents evidencing
the line of credit remain the same. It is anticipated that, as historically has been the practice, the line of credit will be renewed
each year for one additional year for the immediate foreseeable future.</p>

<p style="font-size: 10pt; margin: 0 0 12pt">NTIC believes that a combination of its existing cash and cash equivalents, available
for sale securities, forecasted cash flows from future operations, anticipated distributions of earnings, anticipated fees to NTIC
for services provided to its joint ventures, and funds available through existing or anticipated financing arrangements, will be
adequate to fund its existing operations, investments in new or existing joint ventures or subsidiaries, capital expenditures,
debt repayments, cash dividends and any stock repurchases for at least the next 12 months. During the remainder of fiscal 2018,
NTIC expects to continue to invest in NTIC China, research and development and in marketing efforts and resources for the application
of its corrosion prevention technology in the oil and gas industry and its Natur-Tec&#174; bio-plastics business, although the amounts
of these various investments are not known at this time. In order to take advantage of such new product and market opportunities
to expand its business and increase its revenues, NTIC may decide to finance such opportunities by borrowing under its revolving
line of credit or raising additional financing through the issuance of debt or equity securities. There is no assurance that any
financing transaction will be available on terms acceptable to NTIC or at all, or that any financing transaction will not be dilutive
to NTIC&#8217;s current stockholders.</p>

<p style="font-size: 10pt; margin: 0 0 12pt">NTIC traditionally has used the cash generated from its operations, distributions
of earnings from joint ventures and fees for services provided to its joint ventures to fund NTIC&#8217;s new technology investments
and capital contributions to new and existing subsidiaries and joint ventures. NTIC&#8217;s joint ventures traditionally have operated
with little or no debt and have been self-financed with minimal initial capital investment and minimal additional capital investment
from their respective owners. Therefore, NTIC believes there is limited exposure by NTIC&#8217;s joint ventures that could materially
impact their respective operations and/or liquidity.</p>

<p style="font-size: 10pt; margin: 0 0 12pt"><i>Uses of Cash and Cash Flows</i>. Net cash used in operating activities during the
nine months ended May 31, 2018 was $141,994, which resulted principally from NTIC&#8217;s equity in income from joint ventures,
increases in trade receivables excluding joint ventures, inventories, and prepaid expenses and other, partially offset by NTIC&#8217;s
net income, dividends received from joint ventures, and increases in accounts payable, accrued liabilities, depreciation and amortization.
Net cash provided by operating activities during the nine months ended May 31, 2017 was $2,826,166, which resulted principally
from dividends received from NTIC&#8217;s joint ventures, net income, an increase in accounts payable and depreciation and amortization,
partially offset by NTIC&#8217;s equity in income from joint ventures and an increase in trade receivables.</p>

<p style="font-size: 10pt; margin: 0pt">NTIC&#8217;s cash flows from operations are impacted by significant changes in certain
components of NTIC&#8217;s working capital, including inventory turnover and changes in receivables. NTIC considers internal and
external factors when assessing the use of its available working capital, specifically when determining inventory levels and credit
terms of customers. Key internal factors include existing inventory levels, stock reorder points, customer forecasts and customer
requested payment terms, and key external factors include the availability of primary raw materials and sub-contractor production
lead times. NTIC&#8217;s typical contractual terms for trade receivables excluding joint ventures are traditionally 30 days and
for trade receivables from its joint ventures are 90 days. Before extending unsecured credit to customers, excluding NTIC&#8217;s
joint ventures, NTIC reviews customers&#8217; credit histories and will establish an allowance for uncollectible accounts based
upon factors surrounding the credit risk of specific customers and other information. Accounts receivable over 30 days are considered
past due for most customers. NTIC does not accrue interest on past due accounts receivable. If accounts receivables in excess of
the provided allowance are determined uncollectible, they are charged to selling expense in the period that determination is made.
Accounts receivable are deemed uncollectible based on NTIC exhausting reasonable efforts to collect. NTIC&#8217;s typical contractual
terms for receivables for services provided to its joint ventures are 90 days. NTIC records receivables for services provided to
its joint ventures on an accrual basis, unless circumstances exist that make the collection of the balance uncertain in which case
the fee income will be recorded on a cash basis until there is consistency in payments. This determination is handled on a case
by case basis.</p>

<p style="font-size: 10pt; margin: 0 0 12pt">NTIC experienced an increase in trade receivables as of May 31, 2018 compared to August
31, 2017. Trade receivables excluding joint ventures as of May 31, 2018 increased $2,780,077 compared to August 31, 2017, primarily
related to the timing of collections and the increase in sales. Outstanding trade receivables excluding joint ventures balances
as of May 31, 2018 increased 11 days to an average of 66 days from balances outstanding from these customers as of August 31, 2017.
Outstanding trade receivables from joint ventures as of May 31, 2018 decreased $93,947 compared to August 31, 2017 primarily due
to the timing of payments. Outstanding balances from trade receivables from joint ventures increased as of May 31, 2018 by an average
of 5 days from an average of 57 days from balances outstanding from these customers compared to August 31, 2017. The average days
outstanding of trade receivables from joint ventures as of May 31, 2018 were primarily due to the receivables balances at NTIC&#8217;s
joint ventures in South Korea and Thailand.</p>

<p style="font-size: 10pt; margin: 0 0 12pt">Outstanding receivables for services provided to joint ventures as of May 31, 2018
increased $49,305 compared to August 31, 2017, which resulted in an increase of 3 days of fees receivable outstanding as of May
31, 2018 to an average of 82 days compared to August 31, 2017.</p>

<p style="font-size: 10pt; margin: 0 0 12pt">Net cash used in investing activities for the nine months ended May 31, 2018 was $79,449,
which was primarily the result of additions to property and equipment and additions to patents, partially offset by proceeds from
the sale of available for sale securities. Net cash used in investing activities for the nine months ended May 31, 2017 was $2,398,443,
which was primarily the result of cash used in the purchase of available for sale securities, additions to property and equipment,
and additions to patents.</p>

<p style="font-size: 10pt; margin: 0 0 12pt">Net cash used in financing activities for the nine months ended May 31, 2018 was $1,517,998,
which resulted from dividends paid on NTIC common stock and a dividend paid to a non-controlling interest, partially offset by
proceeds from stock option exercises and purchases under NTIC&#8217;s employee stock purchase plan. Net cash used in financing
activities for the nine months ended May 31, 2017 was $308,689, which resulted from a dividend paid to a non-controlling interest
and the repurchase of common stock, partially offset by proceeds from NTIC&#8217;s employee stock purchase plan and stock option
exercises.</p>

<p style="font-size: 10pt; margin: 0 0 12pt"><i>Share Repurchase Plan</i>. On January 15, 2015, NTIC&#8217;s Board of Directors
authorized the repurchase of up to $3,000,000 in shares of NTIC common stock through open market purchases or unsolicited or solicited
privately negotiated transactions. This program has no expiration date but may be terminated by NTIC&#8217;s Board of Directors
at any time. No repurchases occurred during the nine months ended May 31, 2017. As of May 31, 2018, up to $2,640,548 in shares
of NTIC common stock remained available for repurchase under NTIC&#8217;s stock repurchase program.</p>

<p style="font-size: 10pt; margin: 0 0 12pt"><i>Cash Dividends</i>. On April 25, 2018, NTIC&#8217;s Board of Directors declared
a cash dividend of $0.10 per share of NTIC&#8217;s common stock, paid on May 23, 2018 to stockholders of record on May 9, 2018.
During the nine months ended May 31, 2018, NTIC&#8217;s Board of Directors paid cash dividends totaling $0.30 per share of NTIC&#8217;s
common stock. No cash dividends were declared during fiscal 2017. Although NTIC&#8217;s Board of Directors intends to declare regular
quarterly cash dividends going forward, the declaration of future dividends is not guaranteed and will be determined by NTIC&#8217;s
Board of Directors in light of conditions then existing, including NTIC&#8217;s earnings, financial condition, cash requirements,
restrictions in financing agreements, business conditions and other factors.</p>

<p style="font-size: 10pt; margin: 0pt"><i>Capital Expenditures and Commitments</i>. NTIC spent $500,924 on capital expenditures
during the nine months ended May 31, 2018, which related primarily to the purchase of new equipment. NTIC expects to spend an aggregate
of approximately $500,000 to $600,000 on capital expenditures during fiscal 2018, which it expects will relate primarily to the
purchase of new equipment.</p>

in &#8220;<i>Part II. Item 7, Management&#8217;s Discussion and Analysis of Financial Condition and Results of Operations&#8212;Contractual
Obligations</i>,&#8221; included in NTIC&#8217;s annual report on Form 10-K for the fiscal year ended August 31, 2017.</p>

<p style="font-size: 10pt; margin: 0 0 12pt"><b>Off-Balance Sheet Arrangements</b></p>

<p style="font-size: 10pt; margin: 0 0 12pt">NTIC does not have any relationships with unconsolidated entities or financial partnerships,
such as entities often referred to as structured finance or special purpose entities, which would have been established for the
purpose of facilitating off-balance sheet financial arrangements. As such, NTIC is not materially exposed to any financing, liquidity,
market or credit risk that could arise if NTIC had engaged in such arrangements.</p>

<p style="font-size: 10pt; margin: 0 0 12pt"><b>Inflation and Seasonality</b></p>

<p style="font-size: 10pt; margin: 0 0 12pt">Inflation in the United States and abroad historically has had little effect on NTIC.
Although NTIC&#8217;s business historically has not been seasonal, NTIC believes there is now some seasonality in its business.
NTIC believes its net sales in second fiscal quarter were adversely affected by the long Chinese New Year, the North American holiday
season and overall less corrosion taking place at lower winter temperatures worldwide.</p>

<p style="font-size: 10pt; margin: 0 0 12pt"><b>Market Risk</b></p>

<p style="font-size: 10pt; margin: 0 0 12pt">NTIC is exposed to some market risk stemming from changes in foreign currency exchange
rates, commodity prices and interest rates.</p>

<p style="font-size: 10pt; margin: 0 0 12pt">Because the functional currency of NTIC&#8217;s foreign operations and investments
in its foreign joint ventures is the applicable local currency, NTIC is exposed to foreign currency exchange rate risk arising
from transactions in the normal course of business. NTIC&#8217;s principal exchange rate exposure is with the Euro, the Japanese
Yen, Indian Rupee, Chinese Renminbi, South Korean Won and the English Pound against the U.S. Dollar. NTIC&#8217;s fees for services
provided to joint ventures and dividend distributions from these foreign entities are paid in foreign currencies and thus fluctuations
in foreign currency exchange rates could result in declines in NTIC&#8217;s reported net income. Since NTIC&#8217;s investments
in its joint ventures are accounted for using the equity method, any changes in foreign currency exchange rates would be reflected
as a foreign currency translation adjustment and would not change NTIC&#8217;s equity in income from joint ventures reflected in
its consolidated statements of operations. NTIC does not hedge against its foreign currency exchange rate risk.</p>

<p style="font-size: 10pt; margin: 0 0 12pt">Some raw materials used in NTIC&#8217;s products are exposed to commodity price changes.
The primary commodity price exposures are with a variety of plastic resins.</p>

<p style="font-size: 10pt; margin: 0pt">At the option of NTIC, outstanding advances under NTIC&#8217;s $3,000,000 revolving
line of credit with PNC Bank bear interest at either (a) an annual rate based on LIBOR plus 2.15% for the applicable LIBOR interest
period selected by NTIC or (b) at the rate publicly announced by PNC Bank from time to time as its prime rate, and thus may subject
NTIC to some market risk on interest rates. As of May 31, 2018, NTIC had no borrowings under the line of credit.</p>

<p style="font-size: 10pt; margin: 0 0 12pt"><b>Forward-Looking Statements</b></p>

<p style="font-size: 10pt; margin: 0 0 12pt">This quarterly report on Form 10-Q contains not only historical information, but also
forward-looking statements within the meaning of Section 27A of the Securities Act of 1933, as amended, and Section 21E of the
Securities Exchange Act of 1934, as amended, and are subject to the safe harbor created by those sections. In addition, NTIC or
others on NTIC&#8217;s behalf may make forward-looking statements from time to time in oral presentations, including telephone
conferences and/or web casts open to the public, in press releases or reports, on NTIC&#8217;s Internet web site or otherwise.
All statements other than statements of historical facts included in this report or expressed by NTIC orally from time to time
that address activities, events or developments that NTIC expects, believes or anticipates will or may occur in the future are
forward-looking statements including, in particular, the statements about NTIC&#8217;s plans, objectives, strategies and prospects
regarding, among other things, NTIC&#8217;s financial condition, results of operations and business, the outcome of contingencies
such as legal proceedings and the effect of the liquidation of Tianjin Zerust and the operations of NTIC China. NTIC has identified
some of these forward-looking statements in this report with words like &#8220;believe,&#8221; &#8220;can,&#8221; &#8220;may,&#8221;
&#8220;could,&#8221; &#8220;would,&#8221; &#8220;might,&#8221; &#8220;forecast,&#8221; &#8220;possible,&#8221; &#8220;potential,&#8221;
&#8220;project,&#8221; &#8220;will,&#8221; &#8220;should,&#8221; &#8220;expect,&#8221; &#8220;intend,&#8221; &#8220;plan,&#8221;
&#8220;predict,&#8221; &#8220;anticipate,&#8221; &#8220;estimate,&#8221; &#8220;approximate,&#8221; &#8220;outlook&#8221; or &#8220;continue&#8221;
or the negative of these words or other words and terms of similar meaning. The use of future dates is also an indication of a
forward-looking statement. Forward-looking statements may be contained in the notes to NTIC&#8217;s consolidated financial statements
and elsewhere in this report, including under the heading &#8220;Management&#8217;s Discussion and Analysis of Financial Condition
and Results of Operations.&#8221;</p>

<p style="font-size: 10pt; margin: 0 0 12pt">Forward-looking statements are based on current expectations about future events affecting
NTIC and are subject to uncertainties and factors that affect all businesses operating in a global market as well as matters specific
to NTIC. These uncertainties and factors are difficult to predict and many of them are beyond NTIC&#8217;s control. The following
are some of the uncertainties and factors known to us that could cause NTIC&#8217;s actual results to differ materially from what
NTIC has anticipated in its forward-looking statements:</p>

<p style="font-size: 10pt; margin: 0 0 12pt">All forward-looking statements included in this report are expressly qualified in
their entirety by the foregoing cautionary statements. NTIC wishes to caution readers not to place undue reliance on any forward-looking
statement that speaks only as of the date made and to recognize that forward-looking statements are predictions of future results,
which may not occur as anticipated. Actual results could differ materially from those anticipated in the forward-looking statements
and from historical results, due to the uncertainties and factors described above, as well as others that NTIC may consider immaterial
or does not anticipate at this time. Although NTIC believes that the expectations reflected in its forward-looking statements are
reasonable, NTIC does not know whether its expectations will prove correct. NTIC&#8217;s expectations reflected in its forward-looking
statements can be affected by inaccurate assumptions NTIC might make or by known or unknown uncertainties and factors, including
those described above. The risks and uncertainties described above are not exclusive and further information concerning NTIC and
its business, including factors that potentially could materially affect its financial results or condition, may emerge from time
to time. NTIC assumes no obligation to update, amend or clarify forward-looking statements to reflect actual results or changes
in factors or assumptions affecting such forward-looking statements. NTIC advises you, however, to consult any further disclosures
NTIC makes on related subjects in its annual reports on Form 10-K, quarterly reports on Form 10-Q and current reports on Form 8-K
NTIC files with or furnishes to the Securities and Exchange Commission.</p>

<p style="font-size: 10pt; margin: 0 0 12pt">NTIC is exposed to some market risk stemming from changes in foreign currency exchange
rates, commodity prices and interest rates.</p>

<p style="font-size: 10pt; margin: 0pt">Because the functional currency of NTIC&#8217;s foreign operations and investments
in its foreign joint ventures is the applicable local currency, NTIC is exposed to foreign currency exchange rate risk arising
from transactions in the normal course of business. NTIC&#8217;s principal exchange rate exposure is with the Euro, the Japanese
Yen, Indian Rupee, Chinese Renminbi, South Korean Won and the English Pound against the U.S. Dollar. NTIC&#8217;s fees for services
provided to joint ventures and dividend distributions from these foreign entities are paid in foreign currencies and thus fluctuations
in foreign currency exchange rates could result in declines in NTIC&#8217;s reported net income. Since NTIC&#8217;s investments
in its joint ventures are accounted for using the equity method, any changes in foreign currency exchange rates would be reflected
as a foreign currency translation adjustment and would not change NTIC&#8217;s equity in income from joint ventures reflected in
its consolidated statements of operations. NTIC does not hedge against its foreign currency exchange rate risk.</p>

line of credit with PNC Bank bear interest at either (a) an annual rate based on LIBOR plus 2.15% for the applicable LIBOR interest
period selected by NTIC or (b) at the rate publicly announced by PNC Bank from time to time as its prime rate, and thus may subject
NTIC to some market risk on interest rates. As of May 31, 2018, NTIC had no borrowings under the line of credit.</p>

15d-15(e) under the Securities Exchange Act of 1934, as amended) that are designed to provide reasonable assurance that information
required to be disclosed by NTIC in the reports it files or submits under the Securities Exchange Act of 1934, as amended, is recorded,
processed, summarized and reported, within the time periods specified in the Securities and Exchange Commission&#8217;s rules and
forms and that such information is accumulated and communicated to NTIC&#8217;s management, including NTIC&#8217;s principal executive
officer and principal financial officer, or persons performing similar functions, as appropriate to allow timely decisions regarding

Officer, the effectiveness of the design and operation of NTIC&#8217;s disclosure controls and procedures as of the end of the
period covered in this report. Based on that evaluation, NTIC&#8217;s Chief Executive Officer and Chief Financial Officer concluded
that NTIC&#8217;s disclosure controls and procedures were effective as of the end of such period to provide reasonable assurance
that information required to be disclosed in the reports that NTIC files or submits under the Exchange Act, is recorded, processed,
summarized and reported within the time periods specified in the SEC&#8217;s rules and forms, and that such information is accumulated

<p style="font-size: 10pt; margin: 0 0 12pt">On March 23, 2015, NTIC and NTI Asean LLC (NTI Asean), a majority-owned subsidiary
of NTIC, filed a lawsuit in Tianjin No 1 Intermediate People&#8217;s Court against two individuals, Tao Meng and Xu Hui, related
to breaches of duties and contractual commitments owed to NTI Asean under certain agreements related to NTIC&#8217;s former joint
venture in China, Tianjin Zerust Anti-Corrosion Technologies Ltd. (Tianjin Zerust). The lawsuit alleges, among other things, that
Mr. Tao Meng and Xu Hui have engaged in self-dealing, usurped business opportunities, and received economic benefits that were

Each plan participant&amp;#x2019;s percentage of the overall bonus pool is based upon the number of plan participants, the individual&amp;#x2019;s annual base salary and the individual&amp;#x2019;s position and level of responsibility within the Company. In the case of each of the Company&amp;#x2019;s executive officer participants, &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;75%&lt;/div&gt; of the amount of their individual bonus payout will be determined based upon the Company&amp;#x2019;s actual Adjusted EBITOI for fiscal &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;2018&lt;/div&gt; compared to a pre-established target EBITOI for fiscal &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;2018&lt;/div&gt; and &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;25%&lt;/div&gt; of the payout will be determined based upon such executive officer&amp;#x2019;s achievement of certain pre-established individual performance objectives. The payment of bonuses under the plan are discretionary and &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt; may &lt;/div&gt;be paid to executive officer participants in both cash and shares of the Company&amp;#x2019;s common stock, the exact amount and percentages will be determined by the Company&amp;#x2019;s Board of Directors, upon recommendation of the Compensation Committee, after the completion of the Company&amp;#x2019;s consolidated financial statements for fiscal &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;2018.&lt;/div&gt; There was &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;$1,380,000&lt;/div&gt; accrued for management bonuses for the &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;nine&lt;/div&gt; months ended &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt; May 31, 2018 &lt;/div&gt;compared to &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;$600,000&lt;/div&gt; accrued for management bonuses for the &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;nine&lt;/div&gt; months ended &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt; May 31, 2017.&lt;/div&gt;&lt;/div&gt; &lt;div style=" font-size: 10pt; margin: 0 0 12pt"&gt;Three joint ventures (consisting of the Company&amp;#x2019;s joint ventures in South Korea, India and United States) accounted for &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;51.8%&lt;/div&gt; of the Company&amp;#x2019;s trade joint venture receivables at &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt; May 31, 2018, &lt;/div&gt;and &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;three&lt;/div&gt; joint ventures (consisting of the Company&amp;#x2019;s joint ventures in South Korea, Thailand and India) accounted for &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;60.7%&lt;/div&gt; of the Company&amp;#x2019;s trade joint venture receivables at &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt; August 31, 2017.&lt;/div&gt;&lt;/div&gt; &lt;div style=" font-size: 10pt; margin: 0pt"&gt;From time to time, the Company is subject to various other claims and legal actions in the ordinary course of its business. The Company records a liability in its consolidated financial statements for costs related to claims, including future legal costs, settlements and judgments, where the Company has assessed that a loss is probable and an amount could be reasonably estimated. If the reasonable estimate of a probable loss is a range, the Company records the most probable estimate of the loss or the minimum amount when &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;no&lt;/div&gt; amount within the range is a better estimate than any other amount. The Company discloses a contingent liability even if the liability is &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;not&lt;/div&gt; probable or the amount is &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;not&lt;/div&gt; estimable, or both, if there is a reasonable possibility that material loss &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt; may &lt;/div&gt;have been incurred. In the opinion of management, as of &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt; May 31, 2018, &lt;/div&gt;the amount of liability, if any, with respect to these matters, individually or in the aggregate, will &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;not&lt;/div&gt; materially affect the Company&amp;#x2019;s consolidated results of operations, financial position or cash flows.&lt;/div&gt;&lt;/div&gt;</us-gaap:CommitmentsAndContingenciesDisclosureTextBlock>

This model is based on the core principle that revenue should be recognized to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. The Company has performed a review of the requirements of the new guidance and has identified which of its revenue streams will be within the scope of ASC &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;606.&lt;/div&gt; The Company has applied the &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;five&lt;/div&gt;-step model of the new standard to a selection of contracts within each of its revenue streams and has compared the results to its current accounting practices. The Company is expecting to utilize the modified retrospective transition method of adoption. The Company is continuing to work through the remaining steps of the adoption plan to facilitate adoption effective &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt; September 1, 2018. &lt;/div&gt;As part of this, the Company is assessing changes that might be necessary to information technology systems, processes, and internal controls to capture new data and address changes in financial reporting. The Company will be revising its revenue recognition accounting policy and expanding revenue disclosures to reflect the requirements of ASC &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;606,&lt;/div&gt; which include disclosures related to the nature, amount, timing and uncertainty of revenue and cash flows arising from contracts with customers. Additionally, qualitative and quantitative disclosures are required about customer contracts, significant judgments and assets recognized from the costs to obtain or fulfill a contract. Based on its assessment to date, the Company does &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;not&lt;/div&gt; expect the adoption of this standard to have a material impact on the way it recognizes revenue.&lt;/div&gt; &lt;div style=" font-size: 10pt; margin: 0"&gt;&amp;nbsp;&lt;/div&gt; &lt;div style=" font-size: 10pt; margin: 0pt"&gt;During &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt; February 2016, &lt;/div&gt;the FASB issued ASU &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;No.&lt;/div&gt; &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;2016&lt;/div&gt;-&lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;02,&lt;/div&gt; &lt;div style="display: inline; font-style: italic;"&gt;Leases&lt;/div&gt;.

Upon adoption, the lessee will apply the new standard retrospectively to all periods presented or retrospectively using a cumulative effect adjustment in the year of adoption.

The guidance is effective for fiscal years beginning after &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt; December 15, 2017. &lt;/div&gt;Early adoption is permitted. The Company is currently evaluating the effects of adopting ASU &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;No.&lt;/div&gt; &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;2016&lt;/div&gt;-&lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;15&lt;/div&gt; on its consolidated financial statements.&lt;/div&gt; &lt;div style=" font-size: 10pt; margin: 0"&gt;In &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt; February 2018, &lt;/div&gt;the FASB issued ASU &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;No.&lt;/div&gt; &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;2018&lt;/div&gt;-&lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;02,&lt;/div&gt; &lt;div style="display: inline; font-style: italic;"&gt;Income Statement &amp;#x2013; Reporting Comprehensive Income (Topic &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;220&lt;/div&gt;) Reclassification of Certain Tax Effects from Accumulated Other Comprehensive Income&lt;/div&gt;, which will allow a reclassification from accumulated other comprehensive income to retained earnings for the tax effects resulting from the Tax Cuts and Jobs Act (Tax Reform Act) that are stranded in accumulated other comprehensive income.

It must be applied either in the period of adoption or retrospectively to each period in which the effect of the change in the U.S. federal corporate income tax rate in the Tax Reform Act is recognized.

Subject to adjustment as provided in the &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;2007&lt;/div&gt; Plan, up to a maximum of &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;800,000&lt;/div&gt; shares of the Company&amp;#x2019;s common stock are issuable under the &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;2007&lt;/div&gt; Plan. Options granted under the &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;2007&lt;/div&gt; Plan generally have a term of &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;ten&lt;/div&gt; years and become exercisable over a &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;three&lt;/div&gt;- or &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;four&lt;/div&gt;-year period beginning on the &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;one&lt;/div&gt;-year anniversary of the date of grant. Options are granted at per share exercise prices equal to the market value of the Company&amp;#x2019;s common stock on the date of grant. The Company issues new shares upon the exercise of options. As of &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt; May 31, 2018, &lt;/div&gt;only stock options and stock bonuses had been granted under the &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;2007&lt;/div&gt; Plan.&lt;/div&gt; &lt;div style=" font-size: 10pt; margin: 0pt"&gt;&amp;nbsp;&lt;/div&gt;&lt;div style=" font-size: 10pt; margin: 0pt"&gt;&lt;/div&gt; &lt;div style=" font-size: 10pt; margin: 0 0 12pt"&gt;The maximum number of shares of common stock of the Company available for issuance under the ESPP is &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;100,000&lt;/div&gt; shares, subject to adjustment as provided in the ESPP. The ESPP provides for &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;six&lt;/div&gt;-month offering periods beginning on &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt; September 1 &lt;/div&gt;and &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt; March 1 &lt;/div&gt;of each year. The purchase price of the shares is &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;90%&lt;/div&gt; of the lower of the fair market value of common stock at the beginning or end of the offering period. This discount &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt; may &lt;/div&gt;&lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;not&lt;/div&gt; exceed the maximum discount rate permitted for plans of this type under Section &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;423&lt;/div&gt; of the Internal Revenue Code of &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;1986,&lt;/div&gt; as amended.

The Tax Reform Act makes broad and complex changes to the U.S. tax code that will affect the Company&amp;#x2019;s fiscal year ending &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt; August 31 2018, &lt;/div&gt;including, but &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;not&lt;/div&gt; limited to, reducing the U.S. federal corporate tax rate from &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;35%&lt;/div&gt; to &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;21%&lt;/div&gt; effective &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt; January 1, 2018, &lt;/div&gt;generally eliminating U.S. federal income taxes on dividends received from foreign subsidiaries and joint ventures after &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt; December 31, 2017, &lt;/div&gt;and imposing a &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;one&lt;/div&gt;-time deemed repatriation tax on certain unremitted earnings of foreign subsidiaries and joint ventures. The Company will be subject to a blended U.S. federal tax rate of &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;25.7%&lt;/div&gt; for the fiscal year ending &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt; August 31, 2018 &lt;/div&gt;as a result of the reduction of the U.S. federal corporate tax rate from &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;35%&lt;/div&gt; to &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;21%&lt;/div&gt; effective &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt; January 1, 2018.&lt;/div&gt;&lt;/div&gt; &lt;div style=" font-size: 10pt; margin: 0pt"&gt;&amp;nbsp;&lt;/div&gt;&lt;div style=" font-size: 10pt; margin: 0pt"&gt;&lt;/div&gt; &lt;div style=" font-size: 10pt; margin: 0 0 12pt"&gt;The Company recognized the income tax effects of the Tax Reform Act in its &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;2018&lt;/div&gt; interim consolidated financial statements in accordance with SAB &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;No.&lt;/div&gt; &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;118,&lt;/div&gt; which provides SEC staff guidance for the application of ASC Topic &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;740,&lt;/div&gt; &lt;div style="display: inline; font-style: italic;"&gt;Income Taxes&lt;/div&gt;, in the reporting period in which the Tax Reform Act was signed into law. As such, the Company&amp;#x2019;s financial results reflect the income tax effects of the Tax Reform Act for which the accounting under ASC Topic &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;740&lt;/div&gt; is complete and provisional amounts for those specific income tax effects of the Tax Reform Act for which the accounting under ASC Topic &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;740&lt;/div&gt; is incomplete but a reasonable estimate could be determined.&lt;/div&gt; &lt;div style=" font-size: 10pt; margin: 0 0 12pt"&gt;The Company recorded income tax expense during the &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;three&lt;/div&gt; and &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;nine&lt;/div&gt; months ended &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt; May 31, 2018 &lt;/div&gt;of &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;$181,683&lt;/div&gt; and &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;$1,128,583,&lt;/div&gt; respectively, compared to &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;$237,801&lt;/div&gt; and &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;$480,423&lt;/div&gt; for the &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;three&lt;/div&gt; and &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;nine&lt;/div&gt; months ended &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt; May 31, 2017.&lt;/div&gt;&lt;/div&gt; &lt;div style=" font-size: 10pt; margin: 0 0 12pt"&gt;The Company measures deferred tax assets and liabilities using enacted tax rates that will apply in the years in which the temporary differences are expected to be recovered or paid. Accordingly, the Company&amp;#x2019;s deferred tax assets and liabilities were re-measured to reflect the reduction in the U.S. corporate income tax rate from &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;35%&lt;/div&gt; to &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;21%&lt;/div&gt; effective &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt; January 1, 2018, &lt;/div&gt;resulting in an increase of &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;$700,000&lt;/div&gt; in income tax expense for the &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;nine&lt;/div&gt; months ended &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt; May 31, 2018 &lt;/div&gt;and a corresponding decrease of &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;$700,000&lt;/div&gt; in net deferred tax assets as of &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt; May 31, 2018 &lt;/div&gt;compared to &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt; August 31, 2017. &lt;/div&gt;The &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;$700,000&lt;/div&gt; income tax expense and corresponding decrease in net deferred tax assets represents a provisional estimate based on the Company&amp;#x2019;s current interpretation of the Tax Reform Act and &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt; may &lt;/div&gt;change as the Company receives additional clarification and implementation guidance. &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;No&lt;/div&gt; changes were recorded during the &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;three&lt;/div&gt; months ended &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt; May 31, 2018.&lt;/div&gt;&lt;/div&gt; &lt;div style=" font-size: 10pt; margin: 0 0 12pt"&gt;The &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;one&lt;/div&gt;-time deemed repatriation tax is applicable to the unremitted earnings of the Company&amp;#x2019;s foreign subsidiaries and joint ventures. The Company calculated deemed repatriation tax of &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;$489,000,&lt;/div&gt; which the Company expects to fully offset with foreign tax credit carryforwards for which the Company has &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;not&lt;/div&gt; previously recognized a tax benefit. As a result, the transition tax resulted in &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;zero&lt;/div&gt; increase in income tax expense and income taxes payable for the &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;nine&lt;/div&gt; months ended &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt; May 31, 2018. &lt;/div&gt;The &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;$489,000&lt;/div&gt; transition tax on deemed repatriation of unremitted foreign earnings represents a provisional estimate and is subject to adjustment during the measurement period of up to &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;one&lt;/div&gt; year following the &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt; December 2017 &lt;/div&gt;enactment date of the Tax Reform Act, as provided by recent SEC guidance. &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;No&lt;/div&gt; adjustments were recorded during the &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;three&lt;/div&gt; months ended &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt; May 31, 2018.&lt;/div&gt;&lt;/div&gt; &lt;div style=" font-size: 10pt; margin: 0pt"&gt;The Company continues to analyze the impact of other provisions of the Tax Reform Act on its financial statements and operations, including the impact of the global intangible low-taxed income (GILTI) rules, and the impact of the Tax Reform Act on the Company&amp;#x2019;s indefinite reinvestment assertion with respect to the undistributed earnings of certain foreign subsidiaries and joint ventures. Any additional impacts from the enactment of the Tax Reform Act will be recorded as they are identified during the measurement period as provided for in accordance with SAB &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;No.&lt;/div&gt; &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;118.&lt;/div&gt;&lt;/div&gt;&lt;/div&gt;</us-gaap:IncomeTaxDisclosureTextBlock>

font-style: italic; font-weight: inherit; font-style: normal;"&gt;$18.35,&lt;/div&gt; which was equal to the fair market value of the Company&amp;#x2019;s common stock on the date of grant.&lt;/div&gt; &lt;div style=" font-size: 10pt; margin: 0 0 12pt"&gt;The Company issued &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;891&lt;/div&gt; and &lt;div style="display: inline;

September 1, 2017 &lt;/div&gt;and &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;2016,&lt;/div&gt; respectively, under the Northern Technologies International Corporation Employee Stock Purchase Plan (ESPP). The Company issued &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;985&lt;/div&gt; and &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;1098&lt;/div&gt; shares of common stock on &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt; March 1, 2018 &lt;/div&gt;and &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;2017,&lt;/div&gt; respectively, under the ESPP.&lt;/div&gt; &lt;div style=" font-size: 10pt; margin: 0 0 12pt"&gt;The Company held its &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;2018&lt;/div&gt; Annual Meeting of Stockholders (&lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;2018&lt;/div&gt; Annual Meeting) on &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt; January 12, 2018. &lt;/div&gt;At the &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;2018&lt;/div&gt; Annual Meeting, a proposal to approve an amendment to the Company&amp;#x2019;s Restated Certificate of Incorporation to increase the Company&amp;#x2019;s authorized shares of common stock from &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;10,000,000&lt;/div&gt; to &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;15,000,000&lt;/div&gt; (Share Increase Amendment) was approved by the Company&amp;#x2019;s stockholders by the required vote. The Share Increase Amendment was filed with the Office of the Secretary of State of the State of Delaware on &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt; January 16, 2018 &lt;/div&gt;and it became effective the same day. In determining that the Share Increase Amendment was approved by the required vote, votes cast by brokers, banks or other nominees without instruction from the beneficial owners of certain of our outstanding shares were counted in favor of the proposal in accordance with the rules of the New York Stock Exchange that govern how brokers &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt; may &lt;/div&gt;cast such votes. Because a disclosure in the definitive proxy statement for the &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;2018&lt;/div&gt; Annual Meeting, which was filed on Schedule &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;14A&lt;/div&gt; with the Securities and Exchange Commission (SEC) on &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt; November 27, 2017 (&lt;/div&gt;&lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;2018&lt;/div&gt; Proxy Statement), anticipated that brokers would &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;not&lt;/div&gt; have discretion to vote for the proposal to approve the Share Increase Amendment, a question has been raised as to the validity of the vote taken on the proposal to approve the Share Increase Amendment. The Company believes that the Share Increase Amendment was properly approved and is effective. However, because the description of the authority of brokers to vote on proposals without instruction in the &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;2018&lt;/div&gt; Proxy Statement &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt; may &lt;/div&gt;create some uncertainty as to the effect of the vote obtained at the &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;2018&lt;/div&gt; Annual Meeting and out of an abundance of caution, the Company intends to ask its stockholders at either a special meeting or the next annual meeting of the Company&amp;#x2019;s stockholders to ratify the filing and effectiveness of the Share Increase Amendment pursuant to Delaware law in order to eliminate any uncertainty related to the effectiveness of the Share Increase Amendment. The Company has &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;not&lt;/div&gt; issued, or reserved for issuance, and will &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;not&lt;/div&gt; issue, or reserve for issuance, any of the additional &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;5,000,000&lt;/div&gt; authorized shares as part of the Share Increase Amendment unless the vote at the special or annual meeting of the Company&amp;#x2019;s stockholders is in favor of the ratification of the Share Increase Amendment.&lt;/div&gt; &lt;div style=" font-size: 10pt; margin: 0pt"&gt;During the &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;nine&lt;/div&gt; months ended &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt; May 31, 2017, &lt;/div&gt;the Company repurchased and retired &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;14,525&lt;/div&gt; shares of its common stock at a price of &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;$13.51&lt;/div&gt; per share.&lt;/div&gt; &lt;div style=" font-size: 10pt; margin: 0pt"&gt;&amp;nbsp;&lt;/div&gt; &lt;div style=" font-size: 10pt; margin: 0pt"&gt;&lt;/div&gt; &lt;!-- Field: Page; Sequence: 13 --&gt; &lt;div style=" font-size: 10pt; margin: 0pt"&gt;&lt;/div&gt; &lt;div style=" font-size: 10pt; margin: 0 0 12pt"&gt;During the &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;nine&lt;/div&gt; months ended &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt; May 31, 2017, &lt;/div&gt;stock options to purchase an aggregate of &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;4,000&lt;/div&gt; shares of common stock were exercised at a weighted average exercise price of &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;$10.25&lt;/div&gt; per share.&lt;/div&gt; &lt;div style=" font-size: 10pt; margin: 0 0 12pt"&gt;During the &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;nine&lt;/div&gt; months ended &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt; May 31, 2017, &lt;/div&gt;the Company granted stock options under the &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;2007&lt;/div&gt; Plan to purchase an aggregate of &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;56,677&lt;/div&gt; shares of its common stock to various employees and directors. The weighted average per share exercise price of the stock options was &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;$13.40,&lt;/div&gt; which was equal to the fair market value of the Company&amp;#x2019;s common stock on the date of grant.&lt;/div&gt;&lt;/div&gt;</us-gaap:StockholdersEquityNoteDisclosureTextBlock>

This model is based on the core principle that revenue should be recognized to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. The Company has performed a review of the requirements of the new guidance and has identified which of its revenue streams will be within the scope of ASC <div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;">606.</div> The Company has applied the <div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;">five</div>-step model of the new standard to a selection of contracts within each of its revenue streams and has compared the results to its current accounting practices. The Company is expecting to utilize the modified retrospective transition method of adoption. The Company is continuing to work through the remaining steps of the adoption plan to facilitate adoption effective <div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"> September 1, 2018. </div>As part of this, the Company is assessing changes that might be necessary to information technology systems, processes, and internal controls to capture new data and address changes in financial reporting.

Additionally, qualitative and quantitative disclosures are required about customer contracts, significant judgments and assets recognized from the costs to obtain or fulfill a contract.

The Share Increase Amendment was filed with the Office of the Secretary of State of the State of Delaware on <div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"> January 16, 2018 </div>and it became effective the same day. In determining that the Share Increase Amendment was approved by the required vote, votes cast by brokers, banks or other nominees without instruction from the beneficial owners of certain of our outstanding shares were counted in favor of the proposal in accordance with the rules of the New York Stock Exchange that govern how brokers <div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"> may </div>cast such votes. Because a disclosure in the definitive proxy statement for the <div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;">2018</div> Annual Meeting, which was filed on Schedule <div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;">14A</div> with the Securities and Exchange Commission (SEC) on <div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"> November 27, 2017 (</div><div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;">2018</div> Proxy Statement), anticipated that brokers would <div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;">not</div> have discretion to vote for the proposal to approve the Share Increase Amendment, a question has been raised as to the validity of the vote taken on the proposal to approve the Share Increase Amendment. The Company believes that the Share Increase Amendment was properly approved and is effective. However, because the description of the authority of brokers to vote on proposals without instruction in the <div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;">2018</div> Proxy Statement <div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"> may </div>create some uncertainty as to the effect of the vote obtained at the <div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;">2018</div> Annual Meeting and out of an abundance of caution, the Company intends to ask its stockholders at either a special meeting or the next annual meeting of the Company&#x2019;s stockholders to ratify the filing and effectiveness of the Share Increase Amendment pursuant to Delaware law in order to eliminate any uncertainty related to the effectiveness of the Share Increase Amendment.
