Notes to Condensed Consolidated Financial Statements

(Unaudited)

1. Summary of Significant Accounting Policies

Basis of ~~Presentation:~~Presentation. The accompanying unaudited condensed consolidated financial statements of Lexicon Pharmaceuticals, Inc. (“Lexicon” or the “Company”) include the accounts of Lexicon and its wholly-owned subsidiaries. Intercompany transactions and balances are eliminated in consolidation. These unaudited condensed consolidated financial statements have been prepared in accordance with generally accepted accounting principles for interim financial information and pursuant to the rules and regulations of the Securities and Exchange Commission (“SEC”). Accordingly, they do not include all of the information and footnotes required by generally accepted accounting principles for complete financial statements. ~~We have made certain reclassification adjustments to conform prior-period amounts to the current presentation.~~ In the opinion of management, all adjustments (consisting of normal recurring adjustments) considered necessary for a fair presentation have been included. Operating results for the ~~nine~~three month period ended ~~September 30, 2023~~March 31, 2024 are not necessarily indicative of the results that may be expected for the year ended December 31, ~~2023.~~2024. For further information, refer to the financial statements and footnotes thereto included in Lexicon’s annual report on Form 10-K for the year ended December 31, ~~2022,~~2023, as filed with the SEC.

Use of ~~Estimates~~:Estimates. The preparation of financial statements in conformity with U.S. generally accepted accounting principles (“GAAP”) requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the period. Actual results could differ from those estimates.

~~Cash, Cash Equivalents and Short-Term Investments~~:Significant Accounting Policies. ~~Lexicon considers all highly-liquid investments with original maturities~~There have been no significant changes to our summary of ~~three months or less to be cash equivalents. As of September 30, 2023 and~~significant policies discussed in our annual report on Form 10-K for the year ended December 31, 2022, short-term investments consisted of U.S. treasury bills and corporate debt securities. The Company’s short-term investments are available for use in current operations regardless of the stated maturity date of the security and are classified as available-for-sale securities. The short-term investments are carried at fair value, based on quoted market prices of the securities. The Company does not intend to sell any of its available-for-sale securities prior to their maturity dates. Unrealized gains and losses on such securities are reported as a separate component of stockholders’ equity. Net realized gains and losses, interest and dividends are included in interest income. The cost of securities sold is based on the specific identification method.

~~Inventory~~: ~~Inventory is comprised of the Company’s approved product that it is commercializing in the United States, INPEFA~~® ~~(sotagliflozin). Inventories are determined at the lower of cost or market value with cost determined under the specific identification method.~~

~~Revenue Recognition~~:~~Product Revenues.~~ ~~Product revenues consist of U.S. sales of INPEFA.~~In June 2023, Lexicon began shipping INPEFA to its customers in the U.S. These customers primarily include wholesalers and limited retail pharmacies. The Company is in the process of contracting with certain managed care programs or pharmacy benefit managers (PBMs) and has legislatively mandated contracts with the federal and state governments under which rebates are provided based on product utilization. Product revenues are recognized when control is transferred to the customer upon delivery. Product shipping and handling costs are considered a fulfillment activity when control transfers to the Company’s customers and such costs are included in cost of sales.

~~The Company recognizes product revenue net of applicable estimates of reserves for variable consideration using the expected value method.~~These estimates consider relevant factors such as current contractual and statutory requirements, industry data and forecasted customer buying and payment patterns. Net product revenue includes variable consideration only to the extent that it is probable that a significant reversal in revenue recognized will not occur in a future period. As necessary, these estimates will be adjusted in the period that such variances to actuals become known. Listed below is a further discussion of these reserves and sales return allowances:

~~Customer Credits~~: The Company’s customers are offered various forms of consideration, including allowances, service fees and prompt payment discounts. The Company records allowances, deducts the full amount of prompt payment discounts, and deducts service fees from total product sales when revenues are earned and recognized.

~~Rebates~~: Allowances for rebates include mandated discounts under the Medicaid Drug Rebate Program reflecting amounts owed after final dispensing of the product to participants. The Company’s estimates for rebates is based on statutory discount rates, third party market research data and data from sales to its customers. As rebates are generally invoiced and paid in arrears, the Company accrues an estimate of rebates based on the current quarter’s activity, plus any known unpaid prior quarter rebates.

~~Chargebacks~~: Chargebacks are discounts that occur when healthcare providers purchase directly from a wholesaler. Generally, the healthcare providers purchase INPEFA at a discounted price. The wholesaler, in turn, charges back to Lexicon the difference between the price paid by the wholesaler and the discounted price that the wholesaler’s customer pays for that product.

~~Medicare Part D Coverage Gap~~: The Medicare Part D prescription drug benefit mandates manufacturers to fund a portion of the Medicare Part D insurance coverage gap for prescription drugs sold to eligible patients. The Company’s estimates for the expected Medicare Part D coverage gap are based on sales data received from a third party and projections based on historical data. As funding of the coverage gap is generally invoiced and paid in arrears, the Company accrues an estimate based on the current quarter’s activity, plus any known unpaid prior quarter estimates.

~~Co-payment assistance~~: Patients with commercial insurance who meet certain eligibility requirements are eligible to receive co-payment assistance. The Company accrues a liability for co-payment assistance based on actual program participation and estimates of program redemption using data provided by third-party administrators.

~~Sales returns~~: The Company records allowances for product returns, if appropriate, as a reduction of revenue at the time product sales are recorded based on an assessment of market exclusivity of the product, the patient population, the customers’ return rights and the Company’s historical experience with returns. Because approval is recent and there is a limited number of patients, most customers and retailers carry a limited inventory.

~~Cost of Sales:~~ Cost of sales consists of third-party manufacturing costs, freight and indirect overhead costs associated with sales of INPEFA. The Company began capitalizing inventory in June 2023 following regulatory approval of INPEFA, as the related costs were expected to be recovered through the commercialization of the product. Costs incurred prior to the approval of INPEFA have been recorded as research and development expense in the condensed consolidated statements of comprehensive loss.

~~Research and Development Expenses:~~ Research and development expenses consist of costs incurred for company-sponsored as well as collaborative research and development activities. These costs include direct and research-related overhead expenses and are expensed as incurred. Technology license fees for technologies that are utilized in research and development and have no alternative future use are expensed when incurred. Substantial portions of the Company’s preclinical and clinical trials are performed by third-party laboratories, medical centers, contract research organizations and other vendors. For preclinical studies, the Company accrues expenses based upon estimated percentage of work completed and the contract milestones remaining. For clinical studies, expenses are accrued based upon the number of patients enrolled and the duration of the study. The Company monitors patient enrollment, the progress of clinical studies and related activities to the extent possible through internal reviews of data reported to the Company by the vendors and clinical site visits. The Company’s estimates depend on the timeliness and accuracy of the data provided by the vendors regarding the status of each program and total program spending. The Company periodically evaluates the estimates to determine if adjustments are necessary or appropriate based on information it receives.

~~Net Loss per Common Share:~~ Net loss per common share is computed using the weighted average number of shares of common stock outstanding. Shares associated with stock warrants, stock options and restricted stock units are not included because they are antidilutive due to the Company’s net loss.2023.

3. Fair Value Measurements

The Company uses various inputs in determining the fair value of its investments and measures these assets on a recurring basis. Assets and liabilities recorded at fair value in the condensed consolidated balance sheets are categorized by the level of objectivity associated with the inputs used to measure their fair value. The following levels are directly related to the amount of subjectivity associated with the inputs to fair valuation of these assets and liabilities:

•Level 1 - quoted prices in active markets for identical ~~investments,~~assets, which include U.S. treasury securities

•Level 2 - other significant observable inputs (including quoted prices for similar investments, market corroborated inputs, etc.), which includes corporate debt securities

•Level 3 - significant unobservable inputs

The inputs or methodology used for valuing securities are not necessarily an indication of the credit risk associated with investing in those securities. The following ~~table provides~~tables provide the fair value measurements of applicable Company assets that are measured at fair value on a recurring basis according to the fair value levels defined above as of ~~September 30, 2023~~March 31, 2024 and December 31, ~~2022.~~2023. There were no transfers between Level 1 and Level 2 during the periods presented.

The carrying amount of cash and cash equivalents, prepaid expenses and other assets, accounts payable and accrued expenses are generally considered to be representative of their respective fair values because of the short-term nature of those instruments. The fair value of the Oxford Term Loans (see Note 5) is determined under Level 2 in the fair value hierarchy and approximates carrying value as the loans bear interest at a rate that approximates prevailing market rates for instruments with similar characteristics.

5. Debt Obligations

Oxford Term ~~Loans.~~Loans Overview. ~~In March 2022,~~ Lexicon and one of its subsidiaries entered into a loan and security agreement with Oxford Finance LLC (“Oxford”) in March 2022 (as subsequently amended) that provides up to $150 million in borrowing capacity (the “Oxford Term Loans”). ~~The loan and security agreement was subsequently amended in August 2022, May 2023 and June 2023.~~

The Oxford Term Loans are available in five tranches, each maturing in March 2027. The first two $25 million ~~tranche was~~tranches totaling $50 million were funded in ~~March 2022, the second $25 million tranche was funded in December~~ 2022 and the third $50 million tranche was funded in June 2023. The fourth $25 million tranche iswill be available for draw at Lexicon’s option ~~between December 1~~upon the achievement of specified INPEFA net sales and ~~December 31, 2023.~~until April 15, 2025. An unused fee will be due in the event Lexicon does not draw the full amount when available under the fourth tranche. The fifth $25 million tranche is available for draw at Lexicon’s option, subject to Oxford’s consent, at any time prior to the expiration of the interest-only period in March 2025 as described below. ~~An unused~~

As of March 31, 2024, the carrying value of the Oxford Term Loans on the condensed consolidated balance sheet was $99.9 million, reflecting an unamortized discount of $6.1 million to the face value of long-term debt related to debt issuance costs, the final payment exit fee, ~~will be due in~~and the ~~event Lexicon does not draw~~warrant fair value described below, which are being amortized into interest and other expense throughout the ~~full amount available under~~life of the ~~fourth tranche.~~

term loan using the effective interest rate method. A final payment exit fee of $6.0 million equal to 6% of the amount funded under the Oxford Term Loans is due upon prepayment or maturity, which final payment will be adjusted to 7% of the amount funded upon extension of the interest-only payment period. The final payment exit fee of $6.0 million as of September 30, 2023, in the aggregate for the three borrowed tranches, is recorded as a debt discount on the condensed consolidated balance sheet.maturity.

Oxford Warrants. Concurrent with the funding of each of the first three tranches, Lexicon granted Oxford warrants to purchase 420,673 shares of Lexicon’s common stock at an exercise price of $2.08 per share, 224,128 shares of Lexicon’s common stock at an exercise price of $1.95 per share and 183,824 shares of Lexicon’s common stock at an exercise price of $2.38 per share, respectively. Subject to and upon funding of the fourth tranche, Lexicon will grant Oxford a warrant to purchase shares of its common stock having a value equal to 1.75% of such tranche, as determined by reference to a 10-day average closing price of the shares, and having an exercise price equal to such average closing price. All warrants are exercisable for five years from their respective grant dates and feature a net cashless exercise provision. The Company allocated the proceeds from each term loan tranche to the corresponding warrant using the relative fair value method and used the Black-Scholes model to calculate the fair value of the warrants. ~~The~~These warrants ~~that have been issued in connection with the funding of each tranche~~ reduced the carrying value of long-term debt and are ~~separately~~ classified as equity instruments in additional paid-in capital on the condensed consolidated balance sheet.

As of September 30, 2023, the carrying value of the Oxford Term Loans on the condensed consolidated balance sheet was $99.3 million, reflecting as a discount of $6.7 million to the face value of long-term debt for the final payment exit fee, the warrant fair value,Interest and ~~debt issuance costs, which are being amortized into interest expense throughout the life of the term loan using the effective interest rate method.~~

Principal Payments. Monthly interest-only payments are due during an initial 36-month period from the original March 2022 borrowing date, which may be extended at Lexicon’s option to 48 months if Lexicon maintains compliance with financial covenants relating to (i) net sales of INPEFA following regulatory approval and, (ii) minimum cash balance requirements if Lexicon draws the fourth tranche and following its funding.date. The interest-only period will be followed by an amortization period extending through the maturity date. Payments of $34.8 million, $52.2 million, and $19.0 million, including debt principal and final exit fee payments, will be due during the fiscal years ended December 31, 2025, December 31, 2026 and December 31, 2027, respectively, with respect to all borrowed loan tranches as of ~~September 30, 2023.~~March 31, 2024. Any prepayment of the Oxford Term Loans is subject to prepayment fees of up to 3% which decline over the three years following the funding date of each loan tranche. The Company has classified its debt as long-term based on its intent and ability to refinance with the recent equity financing (see Note 8) if the Company is unable to meet the financial covenants within one year.

Prior to ~~the~~ June 2023 ~~amendment to the loan and security agreement,~~ the Oxford Term Loans bore interest at a floating rate equal to the 30-day U.S. Dollar LIBOR plus 7.90%, but not less than 8.01%, subject to additional interest if an event of default occurs and is continuing. Following ~~such~~the June 2023 amendment to the loan and security agreement, the floating interest rate is currently based on the sum of (a) the 1-month CME Term Secured Overnight Financing Rate (SOFR), (b) 0.10%, and (c) 7.90% for the first and second tranches and 7.00% for the third and fourth tranches. As of ~~September 30, 2023,~~March 31, 2024, the weighted average interest rate of the Oxford Term Loans was 12.9%. During the ~~nine~~three months ended ~~September 30, 2023,~~March 31, 2024, the Company recognized interest expense of ~~$7.7~~$3.8 million, including ~~$1.0~~$0.5 million in amortization of discount and related debt issuance costs.

Restrictive Provisions/Covenants. If an event of default occurs and is continuing, Oxford may declare all amounts outstanding under the loan and security agreement to be immediately due and payable. Additionally, Lexicon may prepay the Oxford Term Loans in whole at its option at any time. ~~Any prepayment of the Oxford Term Loans is subject to prepayment fees for up to three years after the funding of each tranche of the loans.~~

Lexicon’s obligations under the Oxford Term Loans are secured by a first lien security interest in all of the assets of the Company and its subsidiaries. The loan and security agreement contains certain customary representations and warranties, affirmative and negative covenants and events of default applicable to Lexicon and its subsidiaries. The loan and security agreement includes a financial covenant which requires Lexicon to maintain a minimum cash and investments balance of $10 million until the achievement of specified INPEFA net sales. Upon funding of the fourth tranche, the minimum cash and investments balance will increase to $25 million. The loan and security agreement also includes a separate financial covenant

relating to net sales of INPEFA. In March 2024, this covenant was further amended and will be effective as of June 30, 2024. In addition to the financial covenants, additional covenants include those restricting dispositions, fundamental changes to its ~~business, mergers or~~

business, mergers or acquisitions, indebtedness, encumbrances, distributions, investments, transactions with affiliates and subordinated debt. The Company was in compliance with its debt covenants as of ~~September 30, 2023.~~March 31, 2024.

6. Commitments and Contingencies

Operating Lease ~~Obligations~~Obligations.: Lexicon’s operating leases include leases of office space in The Woodlands, Texas and Bridgewater, New Jersey and will expire in August 2025 and January 2034, respectively. Operating lease right-of-use assets and associated lease liabilities are recorded in the condensed consolidated balance sheet at the lease commencement date based on the present value of future lease payments to be made over the expected lease term. As the implicit rate is not determinable in its leases, Lexicon uses its incremental borrowing rate based on the information available at the commencement date to determine the present value of lease payments. Lexicon does not ~~record a right-of-use asset or associated liability for~~apply this accounting to those leases with terms of twelve months or less.

As of ~~September 30, 2023~~March 31, 2024 and December 31, ~~2022,~~2023, the right-of-use assets for the office space leases ~~had a balance~~ of ~~$5.7~~$5.4 million and ~~$6.4~~$5.5 million, respectively, ~~which is~~are separately included in operating lease right-of-use-assets in the condensed consolidated balance sheet. Current ~~and long-term~~ liabilities ~~as of September 30, 2023,~~ relating to the leases were ~~$1.3 million and $5.4 million, respectively, which are~~ included in accrued ~~liabilities and long-term operating lease~~ liabilities in the condensed consolidated balance sheet ~~respectively. Current and long-term liabilities as of December 31, 2022, relating to the leases were $1.3 million and $5.4 million, respectively, which are included~~(as further described in ~~accrued liabilities~~Note 4) and long-term operating lease liabilities are separately included in the condensed consolidated balance ~~sheet, respectively.~~ sheet.

During the three ~~and nine~~ months ended ~~September 30,~~March 31, 2024 and 2023, ~~and 2022,~~ the Company incurred lease expense of $0.4 ~~million and $1.2 million and $0.5 million and $1.2 million, respectively.~~

million. During the ~~nine~~three months ended ~~September 30,~~March 31, 2024 and 2023, ~~and 2022,~~ the Company made cash payments for lease liabilities of ~~$0.5~~$0.3 million and ~~$0.9~~$0.1 million, respectively. As of ~~September 30, 2023~~March 31, 2024 and December 31, ~~2022,~~2023, the weighted-average remaining lease terms were ~~9.1~~8.9 years and ~~9.5~~9 years, respectively, with weighted-average discount rates of 9.6% ~~and 9.6%, respectively.~~.

7. Equity Incentive Awards

Stock-Based ~~Compensation:~~Compensation. The Company has stockholder-approved equity incentive plans that permit the grant of stock options, restricted stock unit awards, and other stock-based awards to employees, directors, and consultants of the Company. Compensation expense related to stock options and restricted stock units ~~(RSUs)~~(“RSUs”) is determined based on the fair value of the award on the date of the grant and is recognized on a straight-line basis over the vesting period in which an employee is required to provide service. Compensation expense of $4.3 million and $3.4 million for the three months ended March 31, 2024 and 2023, respectively, is recorded separately in research and development expense and selling, general, and administrative expense as noted on the Company’s condensed consolidated statements of comprehensive loss.

The fair value of stock options is estimated at the date of grant using the Black-Scholes method requiring the input of subjective assumptions. Because the Company’s employee stock options have characteristics significantly different from those of traded options, and because changes in the subjective input assumptions can materially affect the fair value estimate, in management’s opinion, the existing models do not necessarily provide a reliable single measure of the fair value of its employee stock options. For purposes of determining the fair value of stock options, the Company segregates its options into two homogeneous groups, based on exercise and post-vesting employment termination behaviors, resulting in ~~a change in the~~different assumptions used for expected option lives. Historical data is used to estimate the expected option life for each group. Expected volatility is based on the historical volatility in the Company’s stock price.

The ~~Company utilized the Black-Scholes valuation model for estimating the fair value of the stock option compensation granted, with the~~ following weighted-average assumptions were used for stock options granted in the ~~nine~~three months ended ~~September 30, 2023~~March 31, 2024 and ~~2022:~~2023:


		Expected Volatility		Risk-free Interest Rate		Expected Term	Dividend Rate				Expected Volatility			Risk-free Interest Rate			Expected Term		Dividend Rate

8. Other Capital Agreements

~~Common Stock~~Convertible Preferred Stock. ~~: In June 2023,~~On March 11, 2024, Lexicon ~~sold~~entered into an ~~aggregate of 55,288,460~~agreement with certain accredited investors pursuant to which the Company agreed to sell 2,304,147 shares of its ~~common stock~~Series A Convertible Preferred Stock, par value $0.01 per share, in a private placement at a price of ~~$2.60~~$108.50 per ~~share in a public~~share. The Company received net proceeds of approximately $242 million, after deducting placement agent fees and offering ~~and concurrent~~expenses from the private placement ~~to an~~offering. Each share of preferred stock is convertible into 50 shares of common stock following the approvals listed below. An affiliate of Invus, L.P.~~, resulting~~ elected to participate on the same terms as each other purchaser on a pro rata basis and also agreed to vote at the Company’s 2024 annual meeting of stockholders in ~~net proceeds~~favor of ~~approximately $139 million, after deducting underwriting discounts and commissions and offering expenses.~~the approval of an amendment to the Company’s certificate of incorporation increasing the total authorized common shares thereunder from 300,000,000 to 450,000,000 shares (the “New Charter”).

Following the approval of the New Charter by the Company’s shareholders, the adoption of the New Charter by the Company’s board of directors, and the filing and acceptance of the New Charter by the Secretary of State of Delaware, each share of preferred stock will automatically convert into 50 shares (subject to adjustments) of common stock, or approximately 115 million additional common shares in total. Our convertible preferred shares, as well as other potentially dilutive securities, are not included in the calculation of diluted earnings per common share as we have reported a net loss for the three months ended March 31, 2024 and 2023, and their effect would be anti-dilutive.

We have reported positive results from three Phase 3 clinical trials of sotagliflozin in type 1 diabetes.

We are also developing sotagliflozin as a treatment for hypertrophic cardiomyopathy, or HCM, and are preparing to initiate a Phase 3 clinical trial of sotagliflozin in HCM.

•We are conducting preclinical research and development and preparing to conduct clinical development of compounds from a number of additional drug programs originating from our internal drug discovery efforts.

INPEFA, LX9851 and compounds from a number of additional drug programs originated from our own internal drug discovery efforts, and LX9211 originated from our collaborative neuroscience drug discovery efforts with Bristol-Myers Squibb. Our efforts were driven by a systematic, target biology-driven approach in which we used gene knockout technologies and an integrated platform of advanced medical technologies to systematically study the physiological and behavioral functions of almost 5,000 genes in mice and assessed the utility of the proteins encoded by the corresponding human genes as potential drug targets. We have identified and validated in living animals, or in vivo, more than 100 targets with promising profiles for drug discovery.

We ~~are working~~have worked both independently and through collaborations and strategic alliances with third parties to capitalize on our drug target discoveries and ~~drug discovery~~research and development programs. We seek to retain exclusive or co-exclusive rights to the benefits of certain ~~drug discovery~~research and development programs by developing and commercializing drug candidates from those programs internally, particularly in the United States for indications treated by specialist physicians. We seek to collaborate with other pharmaceutical and biotechnology companies with respect to ~~drug discovery or~~ the research, development and commercialization of certain of our drug candidates, particularly with respect to commercialization in territories outside the United States or commercialization in the United States for indications treated by primary care physicians, or when the collaboration may otherwise provide us with access to expertise and resources that we do not possess internally or are complementary to our own.

We have derived substantially all of our revenues from strategic collaborations and other research and development collaborations and technology licenses, as well as from commercial sales of our approved drug products. To date, we have generated a substantial portion of our revenues from a limited number of sources.

Our operating results and, in particular, our ability to generate additional revenues are dependent on many factors, including the success of our ~~commercial launch~~commercialization of INPEFA in the United ~~States;~~States and the amount of revenues generated from sales of INPEFA; the success of our ongoing ~~nonclinical~~research and ~~clinical~~ development efforts and the ability to obtain necessary regulatory approvals of the drug candidates which are the subject of such efforts; our success in establishing new collaborations and licenses and our receipt of milestones, royalties and other payments under such arrangements; and general and industry-specific economic conditions which may affect research, development and commercialization expenditures.

Our ability to secure future revenue-generating agreements will depend upon our ability to address the needs of our potential future collaborators and licensees, and to negotiate agreements that we believe are in our long-term best interests. We may determine, as we have with ~~certain of our drug candidates,~~INPEFA in heart failure, that our interests are better served by retaining rights to our discoveries and advancing our therapeutic programs to a later stage, which could limit our near-term revenues and increase expenses. Because of these and other factors, our operating results have fluctuated in the past and are likely to do so in the

future, and we do not believe that period-to-period comparisons of our operating results are a good indication of our future performance.

Since our inception, we have incurred significant losses and, as of ~~September 30, 2023,~~March 31, 2024, we had an accumulated deficit of ~~$1.7~~$1.8 billion. Our losses have resulted principally from costs incurred in research and development, selling, general and administrative costs associated with our operations, and non-cash stock-based compensation expenses associated with stock options and restricted stock units granted to employees and consultants. Research and development expenses consist primarily of salaries and related personnel costs, external research costs related to our nonclinical and clinical efforts, material costs, facility costs, depreciation on property and equipment, and other expenses related to our drug discovery and development programs. Selling, general and administrative expenses consist primarily of salaries and related expenses for executive, sales and marketing, and administrative personnel, professional fees and other corporate expenses, including information technology, facilities costs and general legal activities. We expect to continue to incur significant research and development costs in connection with the continuing research and development of our drug candidates and significant selling, general and administrative expenses in connection with our commercial launch of INPEFA. As a result, we will need to generate significantly higher revenues to achieve profitability.

Critical Accounting Policies

The preparation of financial statements in conformity with generally accepted accounting principles requires us to make judgments, estimates and assumptions in the preparation of our condensed consolidated financial statements and accompanying notes. Actual results could differ from those estimates. We believe there have been no significant changes in our critical accounting policies as discussed in our Annual Report on Form 10-K for the year ended December 31, ~~2022.~~2023.

Results of Operations

Revenues

Revenues for the three ~~and nine~~ months ended ~~September 30, 2023~~March 31, 2024 were approximately ~~$0.2~~$1.1 million ~~and $0.5 million, respectively,~~ primarily from product revenues recognized from sales of INPEFA following its regulatory approval in May 2023.

Cost of Sales

Cost of sales during the three ~~and nine~~ months ended ~~September 30, 2023~~March 31, 2024 consist of third-party manufacturing costs ~~freight~~ and ~~indirect overhead costs~~freight associated with sales of INPEFA. Prior to receiving regulatory approval on May 26, 2023, we had completed or begun the manufacturing of certain INPEFA raw materials. These raw materials were either received at “zero-cost” to us in conjunction with a terminated agreement in 2019 or recorded as research and development expense. Based on our expectations for future manufacturing costs, we estimate these amounts totaled approximately $39.0 million. We began capitalizing inventory manufactured subsequent to regulatory approval of INPEFA as the related costs were expected to be recoverable through the commercialization of the product. At March 31, 2024, substantially all of the “zero-cost” INPEFA raw materials remains available to us. The ~~pre-commercialization~~“zero-cost” inventory is expected to be ~~sold~~consumed over approximately the next ~~two years. As a~~three years, which will result ~~cost of sales will reflect~~in a lower average per unit cost of ~~materials.

Interest ~~Expense~~ and Other Expense

Interest and Other Expense. Interest and other expense was $4.9 million and $1.8 million, respectively, during the three months ended March 31, 2024 and 2023, primarily due to the borrowing of additional $50 million in Oxford debt in June 2023.

Our quarterly operating results have fluctuated in the past and are likely to do so in the future, and we believe that quarter-to-quarter comparisons of our operating results are not a good indication of our future performance.

Liquidity and Capital Resources

We have financed our operations from inception primarily through sales of common and preferred stock, contract and milestone payments we received under our collaborations and strategic licenses, target validation, database subscription and technology license agreements, product sales, government grants and contracts, and financing under debt, lease and ~~lease~~other project financing arrangements, as well as from commercial sales of our approved drug products. ~~Our~~

In March 2022, we entered into a loan and security agreement with Oxford that provides up to $150 million in borrowing capacity, available in five tranches, under which $100 million has been funded under the first three tranches. The fourth $25 million tranche is available for draw at our option upon the achievement of specified INPEFA net sales and until April 25, 2025. The fifth $25 million tranche is available for draw at our option, subject to Oxford’s consent, at any time prior to the expiration of the 36-month interest-only payment period. The loan and security agreement includes a financial covenant relating to INPEFA net sales and a separate financial covenant which requires us to maintain a minimum cash and investments balance of $10 million until the achievement of specified INPEFA net sales. Upon funding of the fourth tranche, the minimum cash and investments balance will increase to $25 million.

In December 2023, we entered into an Open Market Sale AgreementSM with Jefferies LLC pursuant to which we may offer and sell shares of our common stock having an aggregate sales price of up to $75 million from time to time through Jefferies as sales agent. As of March 31, 2024, the full amount is still available for issuance under this agreement.

On March 11, 2024, we entered into an agreement with certain accredited investors pursuant to which we agreed to sell 2,304,147 shares of our Series A Convertible Preferred Stock, at a price of $108.50 per share. We received net proceeds of approximately $242 million, after deducting placement agent fees and offering expenses from the private placement offering. Each share of preferred stock will automatically convert into 50 shares of our common stock upon the filing and acceptance of an amendment to our certificate of incorporation by the Secretary of State of Delaware increasing the number of authorized shares of our common stock to 450,000,000 shares. For additional information on the private placement offering, please refer to Note 8 of the Notes to the Condensed Consolidated Financial Statements.

As of ~~September 30,~~March 31, 2024 and December 31, 2023, we had ~~$218.4~~$355.6 million and $170.0 million in cash, cash equivalents and short-term ~~investments. As of December 31, 2022, we had $138.4 million in cash, cash equivalents and short-term investments.~~investments, respectively. We used cash of ~~$111.3~~$55.1 million from operations in the ~~nine~~three months ended ~~September 30, 2023,~~March 31, 2024, largely reflective of the net loss for the period of ~~$127.4~~$48.4 million which included non-cash charges of ~~$9.1~~$4.7 million primarily related to stock-based compensation expense. Investing activities used cash of ~~$101.8~~$110.2 million in the ~~nine~~three months ended ~~September 30, 2023,~~March 31, 2024, primarily due to net purchases of investments. Financing activities provided cash of ~~$188.0~~$239.4 million, primarily from ~~approximately $139.0 million in net proceeds from~~ the issuance of sale of ~~an aggregate of 55,288,460~~2,304,147 shares of ~~common stock~~our Series A Convertible Preferred Stock in a private placement at a price of ~~$2.60~~$108.50 per share in a public offering and concurrent private placement to an affiliate of Invus, L.P. and $50.0 million in net proceeds from the funding of the third tranche under the Oxford Term Loans, partially offset by $0.8 million to repurchase common stock in satisfaction of tax withholding obligations for vested restricted stock units.share.

Other commitments. Upon the regulatory approval of sotagliflozin for the treatment of type 1 diabetes in a major market, we will be required to make certain royalty payments, totaling $4.5 million, in three equal annual installments of $1.5 million.

Under our drug discovery alliance with Bristol-Myers Squibb, we will be required to make a milestone payment of $5 million upon dosing of the first patient in a Phase 3 clinical trial of LX9211.

In July 2022, our subsidiary, Lexicon Pharmaceuticals (New Jersey), Inc., leased a 22,000 square-foot office space in Bridgewater, New Jersey. The term of the lease extends from February 2023 through January 2034 and provides for escalating yearly base rent payments starting at $820,000 and increasing to $986,000 in the final year of the lease..

Our future capital requirements will be substantial and will depend on many factors, including the success of our ~~commercial launch~~commercialization of INPEFA in the United States; the success of our commercial launch of sotagliflozin for patients with type 1 diabetes and CKD, if approved; the success of our ongoing ~~nonclinical~~research and ~~clinical~~ development efforts and the ability to obtain necessary regulatory approvals of the drug candidates which are the subject of such efforts; our success in establishing new collaborations and licenses and our receipt of milestones, royalties and other payments under such

arrangements; the amount and timing of our research, development and commercialization expenditures; the resources we devote to commercializing, developing and supporting our products and other factors. Our capital requirements will also be affected by any expenditures we make in connection with license agreements and acquisitions of and investments in complementary technologies and businesses.

We expect to continue to devote substantial capital resources to the commercialization of ~~INPEFA; to successfully complete~~INPEFA for heart failure; the commercial launch of sotagliflozin for patients with type 1 diabetes and CKD, if approved; the research and development of our ~~planned nonclinical and clinical development efforts with respect to LX9211 and our other~~ drug candidates; and for other general corporate activities. We believe that our current unrestricted cash and investment balances ~~and cash and~~as well as future revenues ~~we expect to derive from strategic and other collaborations and other sources~~ will be sufficient to fund our currently planned operations for at least the next 12 months from the date of this report. ~~During or after this period,~~In future periods, if cash on hand or generated by operations is insufficient to satisfy our liquidity requirements, we will need to obtain additional liquidity through future strategic and other collaborations or sell additional equity or debt securities or obtain additional credit arrangements. If we are unable to obtain adequate financing when needed, we may have to delay or reduce the scope of our commercialization efforts or one or more of our clinical trials ~~or commercialization~~ and other research and development programs. Additional financing may not be available on terms acceptable to us or at all. The sale of additional equity or convertible debt securities may result in additional dilution to our stockholders.

From time to time, our board of directors may authorize us to repurchase shares of our common stock. If and when our board of directors should determine to authorize any such action, it would be on terms and under market conditions that our board of directors determines are in the best interest of us and our stockholders. Any such actions could deplete significant amounts of our cash resources and/or result in additional dilution to our stockholders.

Disclosure about Market Risk

We are exposed to limited market and credit risk on our cash equivalents which have maturities of three months or less at the time of purchase. We had approximately ~~$218.4~~$355.6 million in cash and cash equivalents and short-term investments as of ~~September 30, 2023.~~March 31, 2024. We maintain a short-term investment portfolio which consists of U.S. Treasury bills and corporate debt securities that mature three to 12 months from the time of purchase, which we believe are subject to limited market and credit risk. We currently do not hedge interest rate exposure or hold any derivative financial instruments in our investment portfolio.

We are subject to interest rate sensitivity on our outstanding Oxford Term Loans ~~as they contain~~which bear interest at a floating rate ~~tied~~equal to the 1-month CME Term SOFR rate.

Part II -- Other Information

Item 1. Legal Proceedings

We are from time to time party to claims and legal proceedings that arise in the normal course of our business and that we believe will not have, individually or in the aggregate, a material adverse effect on our results of operations, financial condition or liquidity.

Item 1A. Risk Factors

The following risks and uncertainties are important factors that could cause actual results or events to differ materially from those indicated by forward-looking statements. The factors described below are not the only ones we face and additional risks and uncertainties not presently known to us or that we currently deem immaterial also may impair our business operations.

Risks Related to Our Business and Industry

•We depend heavily on the commercial success of INPEFA in heart failure. If we do not achieve commercial success with INPEFA, our business will suffer significant adverse consequences.

•We depend heavily on our ability to obtain regulatory approval in the United States for sotagliflozin in patients with type 1 diabetes and CKD. If we fail to obtain such regulatory approval, our ~~stock price~~business will ~~likely decline.~~suffer significant adverse consequences.

•We depend heavily on our ability to successfully complete ~~late-stage development~~and obtain positive results from our ongoing PROGRESS Phase 2b clinical trial of LX9211 in ~~diabetic peripheral neuropathic pain.~~DPNP. If we fail to successfully complete and obtain positive results from such ~~late-stage development,~~clinical trial, or if the progress of such clinical trial is delayed beyond our expected timelines, our business will suffer ~~and our stock price will likely decline.~~significant adverse consequences.

•Clinical testing of our drug candidates in humans is an inherently risky and time-consuming process that may fail to demonstrate safety and efficacy, which could result in the delay, limitation or prevention of regulatory approval.

•Our drug candidates are subject to a lengthy and uncertain regulatory process that may not result in the necessary regulatory approvals, which could adversely affect our and our collaborators’ ability to commercialize products.

•The commercial success of ~~INPEFA and~~ any ~~other~~ products that we or our collaborators may develop will depend upon the degree of market acceptance among physicians, patients, health care payers and the medical ~~communit~~y.community.

•If ~~our~~we are unable to maintain an effective sales force, marketing infrastructure and distribution capabilities, ~~are unsuccessful,~~ we will not be able to successfully commercialize ~~INPEFA and~~ any ~~other~~ products that we or our collaborators may develop.

•If we are unable to ~~obtain~~establish adequate coverage and reimbursement from third-party payers for ~~INPEFA and~~ any ~~other~~ products that we or our collaborators may develop, our revenues and prospects for profitability will suffer.

•~~If we are unable~~We may not be able to manufacture ~~INPEFA and any other~~ products that we or our collaborators may develop in commercial quantities, which would impair our ability to commercialize such ~~products would be severely impaired.~~products.

•We and our collaborators are subject to extensive and rigorous ongoing regulation relating to any products that we or our collaborators may ~~commercialize or~~ develop.

•We are subject to certain healthcare laws, regulation and enforcement; our failure to comply with those laws could have a material adverse effect on our results of operations and financial condition.

•Current healthcare laws and regulations and future legislative or regulatory reforms to the healthcare system may negatively affect our revenues and prospects for profitability.

•Our competitors may develop products that impair the value of any products that we or our collaborators may ~~commercialize or~~ develop.

•The outbreak of the novel coronavirus, or COVID-19, ~~historically~~ had an adverse impact on our business operations and clinical trials and another novel coronavirus could adversely affect our business in the future.

2120

Risks Related to Our Capital Requirements and Financial Results

• We will need additional capital in the future and, if it is unavailable, we will be forced to delay, reduce or eliminate our research and development programs. If additional capital is not available on reasonable terms, we will be forced to obtain funds, if at all, by entering into financing agreements on unattractive terms.

• We may not have sufficient capital to support Phase 3 development of LX9211 in DPNP and do not have sufficient capital to support Phase 3 development of LX9211 in neuropathic pain broadly. If we are unable to establish a strategic collaboration or other arrangement for that purpose, our capital needs will be substantially higher and we may be unable to obtain financing sufficient to fund Phase 3 development of LX9211 on acceptable terms, or at all, and may be required to forego or reduce the scope of any such Phase 3 development program.

•We have a history of net losses, and we expect to continue to incur net losses and may not achieve or maintain profitability.

•Our operating results have fluctuated and likely will continue to fluctuate, and we believe that period-to-period comparisons of our operating results are not a good indication of our future performance.

•We have substantial indebtedness that may limit cash flow available to invest in the ongoing needs of our business.

•If we do not effectively manage our affirmative and restrictive covenants under the Oxford Term Loans, our financial condition and results of operations could be adversely affected.

Risks Related to Our Relationships with Third Parties

• We depend on our ability to establish collaborations with pharmaceutical and biotechnology companies for the development and commercialization of our other drug candidates. If we are unable to establish such collaborations, or if pharmaceutical products are not successfully and timely developed and commercialized under such collaborations, our opportunities to generate revenues from our other drug candidates will be greatly reduced.

•Conflicts with our collaborators could jeopardize the success of our collaborative agreements and harm our product development ~~efforts~~.efforts.

•We rely on third parties to carry out our ~~nonclinical~~preclinical studies and clinical trials, which may harm or delay our research and development efforts.

•We lack the capability to manufacture ~~materials for nonclinical studies and clinical trials and~~ commercial supplies ~~for~~of INPEFA and any other products which gain regulatory ~~approval.~~approval and other materials for our research and development activities relating to our drug candidates. Our reliance on third parties to manufacture our ~~approved products~~drugs and drug candidates may harm or delay our research, development and commercialization efforts.

Risks Related to Our Intellectual Property

• If we are unable to adequately protect our intellectual property, third parties may be able to use our products and technologies, which could adversely affect our ability to compete in the market.

•We may be involved in patent litigation and other disputes regarding intellectual property rights and may require licenses from third parties for our planned ~~nonclinical and clinical~~research, development and commercialization activities. We may not prevail in any such litigation or other dispute or be able to obtain required licenses.

•Data breaches and cyber-attacks could compromise our intellectual property or other sensitive information and cause significant damage to our business, reputational harm and financial loss.

Risks Related to Environmental and Product Liability

• We have used hazardous chemicals and radioactive and biological substances in our business. Any claims relating to improper handling, storage or disposal of these substances could be time consuming and costly.

•Our business has a substantial risk of product liability and we face potential product liability exposure far in excess of our limited insurance coverage.

Risks Related to Our Common Stock

• Invus, L.P. and its affiliates own a controlling interest in our outstanding common stock and may have interests which conflict with those of our other stockholders.

• Invus has additional rights under its stockholders’ agreement relating to the membership of our board of directors and under our certificate of incorporation relating to preemptive and consent rights, which provide Invus with substantial influence over significant corporate matters.

•Our stock price may be extremely volatile.

•Future issuances or sales of our common stock, or the perception that such issuances or sales may occur, may depress our stock price.

•If securities or industry analysts do not publish research or publish inaccurate or unfavorable research about our business, our stock price and trading volume could decline.

Further, for any such equity securities which are subject to vesting conditions, the number of equity securities which we may retain in satisfaction of the recipient's tax withholding obligations may be dependent on the continued employment of such
