Forward-looking statements are subject to risks, uncertainties and other factors that could cause actual results to differ materially from those expressed or implied by such statements. Such risks, uncertainties and factors include, but are not limited to: general economic conditions domestically and internationally; insufficient cash flows from operating activities; difficulties in obtaining financing on favorable conditions, or at all; outstanding debt and other financial and legal obligations; lawsuits; competition; industry cycles; feedstock, product and mineral prices; feedstock availability; technological developments; regulatory changes; environmental matters; foreign government instability; foreign legal and political concepts; foreign currency fluctuations; and other risks detailed in Trecora's latest Annual Report on Form 10-K, including but not limited to "Part I, Item 1A.

Management's Discussion and Analysis of Financial Condition and Results of Operations" therein, and in its other filings with the Securities and Exchange Commission (the "SEC"). There may be other factors of which Trecora is currently unaware or deems immaterial that may cause its actual results to differ materially from the forward-looking statements. In addition, to the extent any inconsistency or conflict exists between the information included in this presentation and the information included in Trecora's prior presentations, press releases, reports and other filings with the SEC, the information contained in this presentation updates and supersedes such information. Forward-looking statements are based on current plans, estimates, assumptions and projections, and, therefore, you should not place undue reliance on them.

Disclaimer: Non-GAAP Measures Use of Non-GAAP Measures This presentation includes the use of both U.S. generally accepted accounting principles ("GAAP") and non- GAAP financial measures. Trecora believes certain financial measures, such as EBITDA, Adjusted EBITDA, Adjusted EBITDA Margin, Adjusted Net Income (Loss) and Adjusted Diluted Earnings Per Share, which are non- GAAP measures, provide users of Trecora's financial statements with supplemental information that may be useful in evaluating its operating performance. Trecora believes that such non-GAAP measures, when read in conjunction with its operating results presented under GAAP, can be used to better assess Trecora's performance from period to period and relative to performance of other companies in its industry, without regard to financing methods, historical cost basis or capital structure. These measures are not measures of financial performance or liquidity under GAAP and should be considered in addition to, not as a substitute for, analysis of Trecora's results under GAAP. Tables included in this presentation reconcile each of these Non-GAAP measures to their most directly comparable GAAP measure. Reconciliation of adjusted EBITDA information related to potential 2019 impacts of our turnaround priorities provided in this presentation to the nearest GAAP measure cannot be provided without unreasonable efforts due to not yet being able to estimate the material elements of net income or loss and income taxes for full year 2019. The lack of such reconciling information should be considered when assessing the impact of such information. EBITDA, Adjusted EBITDA and Adjusted EBITDA Margin: Trecora defines EBITDA as net income (loss) plus interest expense (benefit) including derivative gains and losses, income taxes, depreciation and amortization. Trecora defines Adjusted EBITDA as EBITDA plus share-based compensation, plus restructuring and severance expenses, plus losses on extinguished debt, plus or minus equity in AMAK's earnings and losses or gains from equity issuances, and plus or minus restructuring gains or losses on acquisitions. Trecora defines Adjusted EBITDA Margin as Adjusted EBITDA as a percentage of consolidated revenue. Adjusted Diluted Earnings Per Share: Trecora defines Adjusted Diluted Earnings Per Share (or Adjusted EPS) as Diluted Earnings Per Share (or Diluted EPS) excluding the impact of a number of non-recurring items that Trecora does not consider indicative of its on-going performance. 3
