FORWARD - LOOKING STATEMENTS This Presentation includes “forward - looking statements” within the meaning of Section 27A of the Securities Act, Section 21E of the Exchange Act and the “safe harbor” provisions of the United States Private Securities Litigation Reform Act of 1995, each as amended. Forward - looking statements may be identified by the use of words such as “estimate,” “plan,” “project,” “forecast,” “intend,” “expect,” “anticipate,” “believe,” “seek,” or other similar expressions that predict or indicate future events or trends or that are not statements of historical matters. These forward - looking statements include, but are not limited to, statements regarding estimates and forecasts of other financial and performance metrics and projections of market opportunity and market share. These statements are based on various assumptions, whether or not identified in this Presentation, and on the current expectations of the TSHII’s and IRRX’s management and are not predictions of actual performance. These forward - looking statements are provided for illustrative purposes only and are not intended to serve as, and must not be relied on by any investor as, a guarantee, an assurance, a prediction or a definitive statement of fact or probability. Actual events and circumstances are difficult or impossible to predict and will differ from assumptions. Many actual events and circumstances are beyond the control of TSHII and IRRX. These forward - looking statements are subject to a number of risks and uncertainties, including commodity price volatility; low prices for oil and natural gas; inflation; increased operating costs; lack of availability of drilling and production equipment and personnel; environmental risks; weather risks; security risks; drilling and operating risks; regulatory changes; uncertainty in estimating oil and gas reserves and in projecting future rates of production; changes in domestic and foreign business, market, financial, political and legal conditions; the inability of the parties to successfully or timely consummate the Proposed Business Combination, including the risk that any required regulatory approvals are not obtained, are delayed or are subject to unanticipated conditions that could adversely affect the combined company or the expected benefits of the proposed business combination or that the approval of the equity holders of IRRX or TSHII is not obtained; failure to realize the anticipated benefits of the Proposed Business Combination; risks relating to the uncertainty of the projected financial information with respect to TSHII; risks related to the rollout of TSHII’s business and the timing of expected business milestones; the effects of competition on TSHII’s business; supply shortages in the materials necessary for the production of TSHII’s products; risks related to original equipment manufacturers and other partners being unable or unwilling to initiate or continue business partnerships on favorable terms; the termination or reduction of government clean energy and electric vehicle incentives; delays in the construction and operation of production facilities; the amount of redemption requests made by IRRX’s public equity holders; the ability of IRRX or the combined company to issue equity or equity - linked securities in connection with the Proposed Business Combination or in the future; and those factors discussed below in slide four and in IRRX’s final prospectus filed with the SEC on November 10, 2021 under the heading “Risk Factors” and other documents of IRRX filed, or to be filed, with the SEC. If any of these risks materialize or our assumptions prove incorrect, actual results could differ materially from the results implied by these forward - looking statements. There may be additional risks that neither IRRX nor TSHII presently know or that IRRX and TSHII currently believe are immaterial that could also cause actual results to differ from those contained in the forward - looking statements. In addition, forward - looking statements reflect IRRX’s and TSHII’s expectations, plans or forecasts of future events and views as of the date of this Presentation. IRRX and TSHII anticipate that subsequent events and developments will cause IRRX’s and TSHII’s assessments to change. However, while IRRX and TSHII may elect to update these forward - looking statements at some point in the future, IRRX and TSHII specifically disclaim any obligation to do so. These forward - looking statements should not be relied upon as representing IRRX’s and TSHII’s assessments as of any date subsequent to the date of this Presentation. Accordingly, undue reliance should not be placed upon the forward - looking statements.

Disclaimer (cont’d) Private and Confidential 4 USE OF PROJECTIONS This Presentation contains projected financial, production and operating information with respect to TSHII, as applicable. Such projected information constitutes forward - looking information, is for illustrative purposes only and should not be relied upon as necessarily being indicative of future results. The assumptions and estimates underlying such projected information are inherently uncertain and are subject to a wide variety of significant business, economic, competitive and other risks and uncertainties that could cause actual results to differ materially from those contained in the projected information. See “Forward - Looking Statements” section above as well as the risk factors described above. Actual results may differ materially from the results contemplated by the projected information contained in this Presentation, and the inclusion of such information in this Presentation should not be regarded as a representation by any person that the results reflected in such information will be achieved. Neither IRRX’s nor TSHII’s independent auditors have audited, reviewed, compiled or performed any procedures with respect to the projections for the purpose of their inclusion in this Presentation, and accordingly, neither of them expressed an opinion or provided any other form of assurance with respect thereto for the purpose of this Presentation. INFORMATION; NON - GAAP FINANCIAL MEASURES The financial information and data contained in this Presentation is unaudited and does not conform to Regulation S - X promulgated under the Securities Act. Accordingly, such information and data may not be included in, may be adjusted in or may be presented differently in, any proxy statement/prospectus to be filed by IRRX with the SEC. Some of the financial information and data contained in this Presentation, such as EBITDA, EBITDA Margin, Free Cash Flow, and PV - 10 have not been prepared in accordance with United States generally accepted accounting principles (“GAAP”). IRRX and TSHII believe that these non - GAAP financial measures provide useful information to management and investors regarding certain financial and business trends relating to the TSHII’s financial condition and results of operations. IRRX and TSHII believe that the use of these non - GAAP financial measures provides an additional tool for investors to use in evaluating projected operating results and trends in and in comparing TSHII’s financial measures with other similar companies, many of which present similar non - GAAP financial measures to investors. Management does not consider these non - GAAP measures in isolation or as an alternative to financial measures determined in accordance with GAAP. The principal limitation of these non - GAAP financial measures is that they exclude significant expenses and income that are required by GAAP to be recorded in TSHII’s financial statements. In addition, they are subject to inherent limitations as they reflect the exercise of judgments by management about which expenses and income are excluded or included in determining these non - GAAP financial measures. TRADEMARKS AND TRADE NAMES IRRX and TSHII own or have rights to various trademarks, service marks and trade names that they use in connection with the operation of their respective businesses. This Presentation also contains trademarks, service marks and trade names of third parties, which are the property of their respective owners. The use or display of third parties’ trademarks, service marks, trade names or products in this Presentation is not intended to, and does not imply, a relationship with IRRX and TSHII, or an endorsement or sponsorship of IRRX and TSHII. Solely for convenience, the trademarks, service marks and trade names referred to in this Presentation may appear with the ®, TM or SM symbols, but such references are not intended to indicate, in any way, that TSHII or IRRX will not assert, to the fullest extent under applicable law, their rights or the right of the applicable licensor to these trademarks, service marks and trade names.

Gardner Policy Institute, Utah Geological Survey, East Daley Analytics, U.S. Energy Information Administration. • The Utah crude oil processing and refining market lags behind the production potential that resides in the Uinta Basin — Crude oil production in the Uinta Basin has had double digit annual production growth since 2021, essentially doubling output since 2019 — During this same time period, Utah Wax processing and refining capacity has remained stagnant at 83,000 bbl/d • Local refiners lack the capacity to process significant amounts of the waxy crude oil that is native to the Uinta Basin — As a result, producers in the region utilize Gulf Coast and California refineries to offset this production / capacity discrepancy Utah Crude Oil Refining Capacity With crude oil production in the Uinta Basin expected to increase to meet growing national demand, opportunities for new Utah processing facilities and refineries will be met with open arms • There are only 5 refineries currently located in the Salt Lake City area with a total Uinta Wax crude processing capacity of 83 , 000 b/d • 18 refineries are within a 1,000 mile radius of the Uinta Basin, 15 of which are capable of processing Uinta’s waxy crude – but at a small scale • Half of the close proximity refineries are in California, a region especially hostile to the receipt of crude oil • Producers are actively looking for more efficient ways to process their crude without geographical and / or political constraints Demand is there for new Uinta Wax processing facilities in the Uinta Basin, which will provide producers increased operational efficiencies and transport - cost reductions Private and Confidential 17 Waxy Crude Capacity '000 barrels per day Total Capacity '000 barrels per day Refinery Owner 10 15 Woods Cross Silver Eagle 13 32 North Salt Lake Big West Oil 18 40 Woods Cross HollyFrontier 16 56 North Salt Lake Chevron 26 64 North Salt Lake Marathon 83 207 Total

Risk Factors Private and Confidential 24 All references below to the “Company,” “we,” “us” or “our” refer to the combined business of TSHII after giving effect to the Proposed Business Combination with IRRX. The risks presented below are certain of the general risks related to TSHII’s business, industry and operations are not exhaustive. The list below is qualified in its entirety by disclosures contained in future filings by IRRX (or by third parties) with respect to TSHII with the SEC. These risks speak only as of the date of this Presentation, and we make no commitment to update such disclosure. The risks highlighted in future filings with the SEC may differ significantly from, and will be more exhaustive, than those presented below. Risks Related to TSHII’s Business, Industry and Operations ł ł ł ł ł ł ł ł ł ł ł ● A substantial or extended decline in oil and natural gas prices may adversely affect our business, financial condition or results of operations and our ability to meet our capital expenditure obligations, our debt repayment and service obligations, and our financial commitments. The assumptions underlying the TSHII’s financial and production projections may prove inaccurate and are subject to significant risks and uncertainties that could cause actual results to differ materially from forecasted results. Transportation capacity for crude oil, natural gas and water and, in the case of produced and flowback water, disposal and/or recycling capacity, must continue to grow in conjunction with the anticipated growth in drilling activity in and production from the Uinta basin for Uinta Basin forecasts to be realized. The Uinta basin is currently approaching capacity limits in each of these areas. While Uinta basin operators are diligently pursuing all avenues to permit, finance and construct these capacity expansions, there can be no assurance that such expansions will be completed in a timely manner, if at all. TSHII is located in the Uinta Basin in Utah, making us vulnerable to risks associated with operating in a single geographic area. Competitive industry conditions, including competitors with significantly greater resources, may negatively affect our ability to conduct operations. We will be required to fund significant amounts of capital expenditures to execute our business plan, including anticipated capital expenditures to restart TSHII and further increase refining capacity. Our ability to execute the TSHII’s business plan will be dependent upon the successful refurbishment / repurposing, commencement of operations and continuing operation of the Plant. There can be no assurance that TSHII will be restarted and/or repurposed on - time, on budget or at all. Any derivative transactions we enter into may limit our gains and expose us to other risks such as taxes and royalties. Legislation and regulations related to derivative contracts could have an adverse impact on our ability to hedge risks associated with our business. Compliance with environmental and occupational safety and health laws and other government regulations could be costly and could negatively impact our operations. Inflation could adversely impact our ability to control costs, including our operating expenses and capital costs. Risks Related to the Proposed Business Combination ● TSHII will incur higher costs post - business combination as a result of being a public company. Risks Relating to the Organizational Structure and Tax Risks after the Proposed Business Combination ● Our Amended and Restated Certificate of Incorporation may include an exclusive forum provision that identifies the Court of Chancery of the State of Delaware as the exclusive forum for certain litigation, including any derivative actions, which could limit our stockholders’ ability to obtain a favorable judicial forum for disputes with us, our directors, officers or employees.

Risk Factors (cont’d) Private and Confidential 25 ł ł ł ł ł ł ł ● Provisions in our proposed amended and restated certificate of incorporation and Delaware law may inhibit a takeover of us, which could limit the price investors might be willing to pay in the future for our common stock and could entrench management. IRRX is an emerging growth company, and the reduced reporting requirements applicable to emerging growth companies may make our common stock less attractive to investors. Future sales of our common stock by our existing stockholders may cause our stock price to fall. A market for our securities may not develop, which would adversely affect the liquidity and price of our securities. Our securities may be delisted from trading on the NYSE or Nasdaq exchange, which could limit investors’ ability to make transactions in our securities and subject us to additional trading restrictions. Our level of indebtedness could adversely affect our ability to meet our obligations under our indebtedness, react to changes in the economy or our industry and to raise additional capital to fund operations. We could issue additional preferred stock without stockholder approval with the effect of diluting then current stockholder interests, impairing their voting rights and potentially discouraging a takeover that stockholders may consider favorable. Unanticipated changes in effective tax rates or adverse outcomes resulting from examination of our income or other tax returns could adversely affect our financial condition and results of operations.
