Exhibit 99.1

Trecora Resources Reports First Quarter 2018 Results

First Quarter Revenue Increased 29.2% and Prime Product Volume Up 27.1% Year-over-Year

First Quarter Net Income of $2.4 Million or $0.09 per Diluted Share

First Quarter Adjusted EBITDA of $7.2 Million Decreased 2.2% Year-over-Year Following the Impact of a Sharp Increase in Feedstock Costs

AMAK Delivered $0.2 Million Equity in Earnings in the Quarter

Conference Call at 10:00 am ET Tomorrow, May 2

SUGAR LAND, Texas, May 1, 2018 /PRNewswire/ -- Trecora Resources (NYSE: TREC), a leading provider of high purity specialty hydrocarbons and waxes, today announced financial results for the first quarter ended March 31, 2018.

"We delivered broad-based prime product volume growth at South Hampton in the quarter as demand remains strong, and we saw significant improvement in results at Trecora Chemical largely due to our efforts to improve operational execution," said Simon Upfill-Brown, President and CEO. "Particularly noteworthy, our new hydrogenation unit ramped up production through improvements in reliability and efficiency.

"We faced rising input costs in the quarter, most notably a sharp increase in natural gasoline prices, that pressured margins for prime products and by-products," Upfill-Brown continued. "We experienced some additional cost pressures related to distribution and storage costs but are implementing steps to mitigate those costs in the second quarter and beyond. Repairs to Aromax II are progressing as planned with expected start up in the third quarter.

"Following the changes to our organizational structure announced in March, we are beginning to see improvement in plant operations. I believe we are headed in the right direction," concluded Upfill-Brown. "Our focus on organizational effectiveness and improved operational processes position us well to capitalize on continued strong demand from customers. In addition, we are attempting to alleviate margin pressures at South Hampton through price and productivity initiatives."

First Quarter 2018 Financial Results
Total revenue in the first quarter was $71.7 million, compared with $55.5 million in the first quarter of 2017, an increase of 29.2%. The increase in reported revenue was driven by a 34.4% increase in petrochemical sales volume and a 1.3% increase in the average sales price of petrochemical products compared with the first quarter of 2017. The higher average sales price was offset by a 17.4% year-over-year increase in the average per-gallon cost of petrochemical feedstock, which is the basis for the formula pricing for approximately 60% of the Company's petrochemical product sales. Since formula pricing is based upon prior month feedstock averages, sales price increases tend to lag behind higher feedstock costs resulting in lower profit margins in the period reported. The increase in feedstock costs compressed margins for the non-formula portion of prime product sales as well. These are sales which do not have pricing formulas tied to feedstock costs. Due to competitive factors, we were unable to recover the increase in feedstock costs through price increases in the quarter.

Gross profit in the first quarter was $10.1 million, or 14.1% of total revenues, compared with $10.6 million, or 19.1% of total revenues, in the first quarter of 2017. Operating income for the first quarter was $3.6 million, compared with operating income of $4.2 million for the first quarter of 2017.

Net income for the first quarter was $2.4 million, or $0.09 per diluted share, compared with net income of $1.5 million, or $0.06 per diluted share, for the first quarter of 2017. Adjusted net income for the quarter was $2.2 million, or $0.08 per share. Reported net income in the first quarter of 2018 reflected equity in earnings of AMAK of $0.2 million or an estimated $0.01 per diluted share on an after-tax basis as compared to equity in losses of AMAK of $1.0 million or an estimated after tax impact of $(0.03) per diluted share in the year-ago period.

Adjusted EBITDA in the quarter was $7.2 million, representing a 10.0% margin, compared with Adjusted EBITDA of $7.4 million, representing a 13.3% margin for the same period a year ago.

South Hampton Resources
Petrochemical volume in the first quarter was 23.3 million gallons, compared with 17.3 million gallons in the first quarter of 2017. Prime product volume in the first quarter of 2018 was 17.7 million gallons, compared with 13.9 million gallons in the first quarter of 2017. Byproduct volume increased 64.3% year-over-year, to 5.6 million gallons. These volumes are sold at lower margins than our prime products.

International volume represented 24.9% of total petrochemical volume during the quarter, up from 22.7% sequentially and 19.6% from the first quarter of 2017.

TC generated revenues of $9.6 million, down 0.7% from $9.7 million in the first quarter of 2017. TC revenue included $6.4 million of wax product sales, down 1.9%. TC's own product wax revenues were a record for the quarter but total revenues were reduced due to a lack of supply of third party waxes that we distribute in Latin America. At $3.2 million, custom processing fees were up 1.8%, when compared with the first quarter of 2017. Customer demand for custom processing remains solid, and as a result of improved operations, revenues from custom processing grew 14.7% from the fourth quarter of 2017.

Use of Non-GAAP Measures
The Company reports its financial results in accordance with U.S. generally accepted accounting principles ("GAAP"). We believe certain financial measures, such as EBITDA, Adjusted EBITDA, Adjusted EBITDA Margin and Adjusted Net Income, which are non-GAAP measures, provide users of our financial statements with supplemental information that may be useful in evaluating our operating performance. We believe that such non-GAAP measures, when read in conjunction with our operating results presented under U.S. GAAP, can be used to better assess our performance from period to period and relative to performance of other companies in our industry, without regard to financing methods, historical cost basis or capital structure. Such non-GAAP measures should be considered as a supplement to, and not as a substitute for, financial measures prepared in accordance with U.S. GAAP.

These non-GAAP measures have been reconciled to the nearest GAAP measure in the tables below entitled Reconciliation of Selected GAAP Measures to Non-GAAP Measures.
