Reaffirms Need to Elect Directors that are Committed to Improving Company Performance and Exploring a Full Range of Alternatives to Unlock Shareholder Value

Ortelius Advisors, L.P., which collectively with its affiliates is the largest stockholder of Trecora Resources (NYSE: TREC), today delivered an open letter to stockholders.

***

Fellow Stockholders,

Ortelius Advisors, L.P. (together with its affiliates, “Ortelius,” “we,” or “us”) owns approximately 11.3% of the outstanding common stock of Trecora Resources (“Trecora” or the “Company”), making us the Company’s largest stockholder.¹

As we communicated in our February letter, Ortelius believes that Trecora has significant upside potential based on its high-quality assets, favorable industry dynamics, and considerable free cash flow generation capability. However, the Company’s stock price has chronically underperformed its peers, relevant indices and the market. In our view, these unacceptable returns are mainly a result of operational missteps, poor capital allocation decisions and missed strategic opportunities, all of which are self-inflicted, causing stockholders to lose confidence in Trecora’s Board and management team.

Since then, we have actively tried to engage with the Company’s Board to reach constructive outcomes that would strengthen Trecora for the benefit of all stockholders. This has included our proposal to add a number of exceptional individuals with focused industry and capital markets experience to the Board, with a plan to improve operating and financial performance, optimize the capital structure, enhance stockholder communications, and assess a full range of strategic alternatives.

However, over the past month, your Board has refused to genuinely engage with us on any of our attempts to reach a resolution in the best interests of stockholders. Instead, they have repeatedly refused to offer constructive responses and enlisted financial and legal advisors to help maintain the status quo. Based on our interactions with the Company, we are concerned that Trecora is working with advisors on one or both of the following:

1) Seeking to “self-cure” the issues on the Board by identifying new “friendly” directors that can be appointed to make superficial changes to the Board without truly threatening the status quo; and

2) Pursuing a face-saving transaction, despite the likelihood of an inferior result, given the Company’s depressed valuation and lack of negotiating leverage.

Given this Board’s history of poor decision-making regarding M&A, we are particularly concerned that stockholders will be harmed and disenfranchised by a transaction overseen by this group of directors.

Instead of wasting precious time and stockholder capital on half-measures and entrenchment tactics, the Company should be working with us on real solutions. With the right leadership, Trecora can, in short order, address operational and financial issues that have plagued performance. The Company’s disappointing 2022 guidance is a clear indication that management is failing. The mid-point of Trecora’s projected EBITDA remains below the level achieved in 2016, despite a dominant position as one of two domestic producers of high-purity pentane and hexane solvents, an advantageous market position in an industry with inelastic demand, and significant capital expenditures.

We believe there are multiple paths to building and unlocking intrinsic value over the near- and long-term, and that our director nominees are well-qualified to assess the options and opportunities available to the Company with a fresh perspective, and without the biases that exist on the current Board.

Given our conviction that substantial change to the Board is necessary to protect the interests of stockholders, Ortelius will continue its campaign to elect its candidates to the Board at this year’s Annual Meeting of Stockholders. We look forward to engaging with you and earning your support as Ortelius works towards effecting positive change at Trecora.
