Basis of Consolidation – LSB and its subsidiaries are consolidated in the accompanying condensed consolidated financial statements. LSB is a holding company with no significant operations or assets other than cash, cash equivalents, short-term investments and investments in its subsidiaries. All material intercompany accounts and transactions have been eliminated. Certain prior period amounts reported in our condensed consolidated financial statements and notes thereto have been reclassified to conform to current period presentation.

Nature of Business – We are engaged in the manufacture and sale of chemical products. The chemical products we primarily manufacture, market and sell are ammonia, fertilizer grade ammonium nitrate (“AN” and “HDAN”) and urea ammonium nitrate ("UAN") for agricultural applications, high purity and commercial grade ammonia, high purity AN, sulfuric acids, concentrated, blended and regular nitric acid, mixed nitrating acids, carbon dioxide and diesel exhaust fluid for industrial applications and industrial grade AN (“LDAN”) and solutions for the mining industry. We manufacture and distribute our products in four facilities; three of which we own and are located in El Dorado, Arkansas (the “El Dorado Facility”); Cherokee, Alabama (the “Cherokee Facility”); and Pryor, Oklahoma (the “Pryor Facility”); and one of which we operate on behalf of Covestro in Baytown, Texas.

Sales to customers include farmers, ranchers, fertilizer dealers and distributors primarily in the ranch land and grain production markets in the United States (“U.S.”); industrial users of acids throughout the U.S. and parts of Canada; and explosive manufacturers in the U.S. and parts of Mexico, Canada and the Caribbean.

These interim results are not necessarily indicative of results for a full year due, in part, to the seasonality of our sales of agricultural products and the timing of performing our major plant maintenance activities. Our selling seasons for agricultural products are primarily during the spring and fall planting seasons, which typically extend from March through June and from September through November.

Use of Estimates – The preparation of condensed consolidated financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates.

Short-Term Investments - Investments, which consist of U.S. treasury bills with an original maturity up to and less than 52 weeks, are considered short-term investments and are classified as Level 1. We plan to hold these investments to maturity and have a history of holding investments to maturity. These investments are carried at cost which approximated fair value for the period ended March 31, 2023. Due to the nature of these investments, as U.S. treasury securities, no impairment is anticipated. Our estimate of expected losses is incorporated into the review of the investments' fair value quarterly.

Accounts Receivable – Our accounts receivable are presented at net realizable value. This value includes an appropriate allowance for estimated uncollectible accounts to reflect any estimate of expected loss anticipated on accounts receivable balances. Our estimate is based on historical experience and periodic assessment of outstanding accounts receivable, particularly those accounts that are past due (based upon the terms of the sale). Our periodic assessment is based on our best estimate of amounts that are not recoverable which includes a present collectability review and forward looking assessment, where applicable.

Equity Awards – Equity award transactions with employees are measured based on the estimated fair value of the equity awards issued. For equity awards with service conditions that have a graded vesting period, we recognize compensation cost on a straight-line basis over the requisite service period for the entire award. Forfeitures are accounted for as they occur. We may issue new shares of common stock or may use treasury shares associated with the equity awards.

In January 2023, the compensation committee of our Board of Directors (“Board”) approved the grant of 171,641 shares of time-based restricted stock units and 171,641 shares of performance-based restricted stock units to certain executives and employees under our 2016 Long Term Incentive Plan (as Amended and Restated on March 4, 2021). The time-based restricted stock units will vest at the end of each one-year period at the rate of one-third per year for three years. The performance-based restricted stock units will vest on the third anniversary of the grant date subject to the achievement of a market metric established by the Board as set out in the grant. Upon the third anniversary the grants may be modified in a range between 0% and 200% based upon achievement of the market metric. The

unvested restricted units carry dividend and voting rights contingent upon the vesting and lapsing of restriction. Sales of these units are restricted prior to the date of vesting. Pursuant to the terms of the underlying restricted stock unit agreements, unvested restricted shares will immediately vest upon the occurrence of a change in control (as defined by agreement), or a certain portion will immediately vest upon termination without cause or death.

Contingencies – Certain conditions may exist which may result in a loss, but which will only be resolved when future events occur. We and our legal counsel assess such contingent liabilities and such assessment inherently involves an exercise of judgment. If the assessment of a contingency indicates that it is probable that a loss has been incurred, we would accrue for such contingent losses when such losses can be reasonably estimated. If the assessment indicates that a potentially material loss contingency is not probable but reasonably possible, or is probable but cannot be estimated, the nature of the contingent liability, together with an estimate of the range of possible loss if determinable and material, would be disclosed. Estimates of potential legal fees and other directly related costs associated with contingencies are not accrued but rather are expensed as incurred. Loss contingency liabilities are included in current and noncurrent accrued and other liabilities and are based on current estimates that may be revised in the near term. In addition, we recognize contingent gains when such gains are realized or when the contingencies have been resolved (generally at the time a settlement has been reached).

Derivatives, Hedges and Financial Instruments – Derivatives are recognized in the balance sheet and measured at fair value. Changes in fair value of derivatives are recorded in results of operations unless the normal purchase or sale exceptions apply, or hedge accounting is elected.

The fair value amounts recognized for our derivative contracts executed with the same counterparty under a master netting arrangement may be offset. We have the choice to offset or not, but that choice must be applied consistently. A master netting arrangement exists if the reporting entity has multiple contracts with a single counterparty that are subject to a contractual agreement that provides for the net settlement of all contracts through a single payment in a single currency in the event of default on or termination of any one contract. Offsetting the fair values recognized for the derivative contracts outstanding with a single counterparty results in the net fair value of the transactions reported as an asset or a liability in the balance sheet. When applicable, we present the fair values of our derivative contracts under master netting agreements using a gross fair value presentation.

Assets and liabilities measured at fair value are classified using the following hierarchy, which is based upon the transparency of inputs to the valuation as of the measurement date:

Level 1 - Valuations of contracts classified as Level 1 are based on quoted prices in active markets for identical contracts.

Level 2 - Valuations of contracts classified as Level 2 are based on quoted prices for similar contracts and valuation inputs other than quoted prices that are observable for these contracts.

Level 3 - Valuations of assets and liabilities classified as Level 3 are based on prices or valuation techniques that require inputs that are both unobservable and significant to the overall fair value measurement.

Recently Issued Accounting Pronouncements

Changes to U.S. GAAP are established by the FASB in the form of accounting standards updates (“ASUs”) to the FASB’s Accounting Standards Codification. We consider the applicability and impact of all ASUs. ASUs issued and outstanding or that became effective since January 1, 2023 through the date of these financial statements were assessed and determined not to be applicable or are expected to have minimal impact on our condensed consolidated financial position and results of operations.

The following weighted-average shares of securities were not included in the computation of diluted net income per common share as their effect would have been antidilutive:

Our long-term debt consists of the following:
