February 27, 2025 Q4'24 Earnings Presentation Exhibit 99.1

Forward-Looking Statements Statements in this presentation that are not historical are forward-looking statements within the meaning of the U.S. Private Securities Litigation Reform Act of 1995. These forward-looking statements, which are subject to known and unknown risks, uncertainties and assumptions about us, may include , but are not limited to, statements regarding: our business strategy; anticipated future operating results and operating expenses, cash flows, capital resources and liquidity; trends, opportunities and risks affecting our business, industry and financial results; our ability to successfully leverage our existing business platform and portfolio of assets to produce low carbon products and execute our strategy to become a leader in the energy transition in the chemical industry; the availability of raw materials; production volumes at our production facilities; and the anticipated cost and timing of our capital projects, including turnarounds. Forward-looking statements can generally be identified by words or phrases such as “anticipate,” “believe,” “could,” “estimate,” “expect,” “may,” “plan,” “potential,” “should,” "will," “would,” and similar words or phrases, as well as by discussions of strategy, plans or intentions. These statements are only predictions based on our current expectations and projections about future events. There are important factors that could cause our actual results, level of activity, performance or actual achievements to differ materially from the results, level of activity, performance or anticipated achievements expressed or implied by the forward-looking statements. Significant risks and uncertainties may relate to, but are not limited to, business and market disruptions, market conditions and price volatility for our products and feedstocks, global and regional economic downturns, that adversely affect the demand for our end-use products; disruptions in production at our manufacturing facilities; and other financial, economic, competitive, environmental, political, legal and regulatory factors. These and other risk factors are discussed in the Company’s filings with the Securities and Exchange Commission, including but not limited to our most recent Annual Report on Form 10-K. Moreover, we operate in a very competitive and rapidly changing environment. New risks and uncertainties emerge from time to time, and it is not possible for our management to predict all risks and uncertainties, nor can management assess the impact of all factors on our business or the extent to which any factor, or combination of factors, may cause actual results to differ materially from those contained in any forward-looking statements. Although we believe the expectations reflected in the forward-looking statements are reasonable, we cannot guarantee future results, level of activity, performance or achievements. Neither we nor any other person assumes responsibility for the accuracy or completeness of any of these forward-looking statements. You should not rely upon forward-looking statements as predictions of future events. Unless otherwise required by applicable laws, we undertake no obligation to update or revise any forward-looking statements, whether because of new information or future developments.

Stockholder Rights Plan in Place to Preserve Substantial NOL’s Our Section 382 Stockholder Rights Plan as amended and restated (the “Rights Plan”), is intended to protect our substantial net operating losses (“NOLs”), carryforwards and other tax attributes. We can generally use our NOLs and other tax attributes to reduce federal and state income tax that would be paid in the future. Our ability to use our NOLs could be substantially limited if we experience an “ownership change,” as defined under Section 382 of the Internal Revenue Code of 1986, as amended (the “Code”), and the Rights Plan has been designed to help prevent such an “ownership change.” The Rights Plan provides that if any person becomes the beneficial owner (as defined in the Code) of 4.9% or more of our common stock, stockholders other than the triggering stockholder will be entitled to acquire shares of common stock at a 50% discount or LSB may exchange each right held by such holders for one share of common stock. Under the Rights Plan, any person which currently owns 4.9% or more of LSB’s common stock may continue to own its shares of common stock but may not acquire any additional shares without triggering the Rights Plan. Our Board of Directors has the discretion to exempt any person or group from the provisions of the Rights Plan. The Rights Plan is in effect until August 22, 2026, unless terminated earlier in accordance with its terms.

Solid year-over-year increases in nitric acid and AN sales volumes UAN volumes benefitted from Q3’24 Pryor urea capacity expansion Completed injury-free turnaround of Cherokee ammonia plant Outlook for nitrogen demand and pricing remains favorable Low carbon ammonia projects progressing Q4’ 24 Overview Adjusted EBITDA is a non-GAAP financial measure. See the discussion and reconciliation in the appendix.

Industrial Market Overview(1) Sources: Federal Reserve Economic Data Industrial business stable with potentially improving outlook Steady demand for nitric acid supported by the strength of the U.S. economy and robust consumer spending levels U.S. new housing starts and auto production relatively steady for past two years; both poised to increase to the extent U.S. interest rates decrease Demand for ammonium nitrate (AN) bolstered by U.S. mining of metals, including copper for data centers and technology infrastructure, as well as quarrying/aggregate production for infrastructure upgrade and expansion Copper prices surged over the past year and currently sit above multi-year averages and exceed our estimate for cash production costs Improvement in new housing starts would drive U.S. aggregate production further strengthening AN demand

Nitrogen Product Pricing and Input Costs(1) Sources: USDA, Green Markets® A Bloomberg Company , Barcharts.com, eia.gov, Federal Reserve Economic Data; Natural Gas Costs derived from forward strips as of 2/21/25 Nitrogen product prices holding up well UAN prices supported by global urea price strength; US becoming a net exporter amidst historically low imports Urea prices benefiting from sustained global demand, particularly from India and ongoing Chinese export bans Well balanced ammonia distribution channel inventories heading into Spring planting season U.S. gas prices projected to remain a cost advantage for domestic nitrogen producers relative to European producers as global LNG demand grows Spot Prices February 26, 2025 February 26, 2024 Tampa Ammonia $460 / MT $445/ MT UAN (NOLA) $290 / ST $245 / ST Natural Gas (NYMEX Spot Price) $3.86/ MMBtu $1.66/ MMBtu

Grain Price Trends(1) U.S. corn prices projected to rally into 2025 Corn futures prices have risen from Q3’24 lows reflecting USDA outlook for smaller supplies and decline in ending stocks relative to previous expectations USDA forecasts for 2025 stocks-to-use ratio (STU) expected lower than 10-year average Increases in U.S. exports with production challenges in international growing regions potentially supportive of corn prices Grain prices projected to remain at attractive levels relative to overall nitrogen costs Sources: USDA, Argus, Bloomberg, EIA, Management Estimates, Barcharts.com Corn/Wheat $/bu Soybean $/bu

Appendix

EBITDA and Adjusted EBITDA Reconciliation (1) EBITDA is defined as net income (loss) plus interest expense and interest income net, plus loss (or less gain) on extinguishment of debt, plus depreciation and amortization (D&A) (which includes D&A of property, plant and equipment and amortization of intangible and other assets), plus provision (or less benefit) for income taxes. We believe that certain investors consider EBITDA a useful means of measuring our ability to meet our debt service obligations and evaluating our financial performance. EBITDA has limitations and should not be considered in isolation or as a substitute for net income (loss), operating income (loss), cash flow from operations or other consolidated income or cash flow data prepared in accordance with GAAP. Because not all companies use identical calculations, this presentation of EBITDA may not be comparable to a similarly titled measure of other companies. The above table provides a reconciliation of net income (loss) to EBITDA for the periods indicated. (2) Adjusted EBITDA is reported to show the impact of non-cash stock-based compensation, one time/non-cash or non-operating items-such as, one-time income or fees, loss (gain) on sale of a business and/or other property and equipment, certain fair market value (FMV) adjustments, and consulting costs associated with reliability and purchasing initiatives (Initiatives). We historically have performed Turnaround activities on an annual basis, however we are moving towards extending Turnarounds to a two or three-year cycle. Rather than being capitalized and amortized over the period of benefit, our accounting policy is to recognize the costs as incurred. Given these Turnarounds are essentially investments that provide benefits over multiple years, they are not reflective of our operating performance in a given year. As a result, we believe it is more meaningful for investors to exclude them from our calculation of adjusted EBITDA used to assess our performance. We believe that the inclusion of supplementary adjustments to EBITDA is appropriate to provide additional information to investors about certain items. The above table provides reconciliations of EBITDA excluding the impact of the supplementary adjustments.
