Notes to Condensed Consolidated Financial Statements (Unaudited) 1. Summary of Significant Accounting Policies Basis of 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. Lexicon has 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 three month period ended March 31, 2025 are not necessarily indicative of the results that may be expected for the year ended December 31, 2025. 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, 2024, as filed with the SEC. Use of 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. Significant Accounting Policies. There have been no significant changes to our summary of significant policies discussed in our annual report on Form 10-K for the year ended December 31, 2024. Recent Accounting Pronouncements Issued But Not Yet Adopted . In December 2023, the FASB issued ASU 2023-09, Income Taxes (Topic 740) – Improvements to Income Tax Disclosures , which is effective prospectively for annual periods beginning after December 15, 2024. Early adoption is permitted for both standards. The Company does not expect this accounting pronouncement to have a material impact on the financial statements. 7 2. Cash and Cash Equivalents and Investments The fair value of cash and cash equivalents and investments held are as follows: As of March 31, 2025 Amortized Cost Gross Unrealized Gains Gross Unrealized Losses Estimated Fair Value (in thousands) Cash and cash equivalents $ 62,888 $ — $ — $ 62,888 Securities maturing within one year: U.S. treasury securities 110,114 21 ( 3 ) 110,132 Corporate debt securities 21,812 10 ( 3 ) 21,819 Total short-term investments $ 131,926 $ 31 $ ( 6 ) $ 131,951 Total cash and cash equivalents and short-term investments $ 194,814 $ 31 $ ( 6 ) $ 194,839 As of December 31, 2024 Amortized Cost Gross Unrealized Gains Gross Unrealized Losses Estimated Fair Value (in thousands) Cash and cash equivalents $ 66,656 $ — $ — $ 66,656 Securities maturing within one year: U.S. treasury securities 127,884 106 — 127,990 Corporate debt securities 43,299 30 ( 18 ) 43,311 Total short-term investments $ 171,183 $ 136 $ ( 18 ) $ 171,301 Total cash and cash equivalents and short-term investments $ 237,839 $ 136 $ ( 18 ) $ 237,957 As of March 31, 2025 and December 31, 2024, Lexicon’s investments in an unrealized loss position had an estimated fair value of $ 57.3 million and $ 12.9 million, respectively. There were no realized gains or losses during either of the three month periods ended March 31, 2025 and 2024. 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 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 8 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 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. There were no transfers between Level 1 and Level 2 during the periods presented. Assets at Fair Value as of March 31, 2025 Level 1 Level 2 Level 3 Total (in thousands) Cash and cash equivalents $ 62,888 $ — $ — $ 62,888 Short-term investments 110,132 21,819 — 131,951 Total cash and cash equivalents and short-term investments $ 173,020 $ 21,819 $ — $ 194,839 Assets at Fair Value as of December 31, 2024 Level 1 Level 2 Level 3 Total (in thousands) Cash and cash equivalents $ 66,656 $ — $ — $ 66,656 Short-term investments 127,990 43,311 — 171,301 Total cash and cash equivalents and short-term investments $ 194,646 $ 43,311 $ — $ 237,957 The carrying amount of cash and cash equivalents, prepaid expenses and other assets, accounts payable, accrued expenses and current portion of long-term debt 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 6) 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. 4. Supplemental Financial Information The following tables show the Company’s additional balance sheet information: Estimated Useful Lives As of March 31, As of December 31, In Years 2025 2024 (in thousands) Property and Equipment: Computers and software 3 - 5 $ 2,003 $ 2,003 Furniture and fixtures 5 - 7 389 389 Leasehold improvements 3 - 7 2,178 2,178 Total property and equipment 4,570 4,570 Less: Accumulated depreciation and amortization ( 2,262 ) ( 2,086 ) Net property and equipment $ 2,308 $ 2,484 9 As of March 31, As of December 31, 2025 2024 (in thousands) Accrued Liabilities: Accrued research and development services $ 6,231 $ 12,251 Accrued compensation and benefits 3,775 14,712 Short-term lease liability 1,044 1,175 Other 1,898 2,309 Total accrued liabilities $ 12,948 $ 30,447 As of March 31, 2025 and December 31, 2024, $ 1.1 million and $ 8.8 million of accrued severance is included in accrued compensation and benefits within accrued liabilities on the condensed consolidated balance sheet as noted in the table above. 5. Collaborations and Strategic Alliances Novo Nordisk . In March 2025, the Company entered into an exclusive license agreement (the “License Agreement”) with Novo Nordisk A/S for the worldwide development, manufacture and commercialization of LX9851, the Company’s preclinical drug candidate for obesity and associated cardiometabolic disorders. Under the License Agreement, the Company granted Novo Nordisk an exclusive, worldwide, royalty-bearing right and license under its patent rights and know-how to develop, manufacture and commercialize LX9851. In April 2025, the Company received an upfront payment of $ 45 million under the License Agreement and is eligible to receive (a) up to an aggregate of $ 485 million upon the achievement of specified regulatory and commercial launch milestones and (b) up to an aggregate of $ 475 million upon the achievement of specified sales milestones. The Company is also entitled to tiered, escalating royalties ranging from single-digit to low-double-digit percentages of annual net sales of LX9851, subject to customary royalty reduction provisions. Under the License Agreement, the Company is also required to use commercially reasonable efforts to complete agreed-upon IND-enabling activities for LX9851 pursuant to an approved research plan as well as provide clinical supply of LX9851 to Novo Nordisk at an agreed upon transfer price for a specified time period. For accounting purposes, pursuant to ASC 606, Revenue from Contracts with Customers , the Company determined that its obligation to provide the licensed technology and perform the IND-enabling activities is a single combined performance obligation and allocated the entire $ 45 million upfront payment to this single combined performance obligation. The Company identified the obligation to provide clinical supply of LX9851 at an agreed upon transfer price for a specified time period as a separate performance obligation, but allocated none of the $ 45 million upfront payment to the clinical supply obligation as the supply is being offered subject to reasonable and customary contract manufacturing terms at its stand-alone selling price. As of March 31, 2025, the Company had provided the licensed technology under its patent rights and know-how to develop, manufacture and commercialize LX9851, but had not yet completed any of the IND-enabling activities. Accordingly, the $ 45 million upfront payment was recorded as accounts receivable and as deferred revenue on the condensed consolidated balance sheet. The Company will recognize such amount as revenue using the input method over the period the IND-enabling activities are performed. Any future milestone or royalty payments that the Company would be eligible to receive were excluded from the upfront payment, as all milestone or royalty amounts were fully constrained based on the probability of achievement. Any future milestone payments or royalties the Company is entitled to receive upon achievement of future sales of the licensed products by Novo Nordisk will be recognized when the related sales occur. The Company also concluded that the License Agreement is not a collaborative agreement under ASC 808, Collaborative arrangements , as Novo Nordisk is responsible for all regulatory and commercialization activities for LX9851 as well as conducting any additional clinical trials required to obtain such regulatory approvals. Viatris . In October 2024, the Company entered into an exclusive license agreement with Viatris Inc. for the development and commercialization of sotagliflozin in all markets outside of the United States and Europe pursuant to which the Company received an upfront payment of $ 25 million. For additional information, please refer to the Company’s Annual Report on Form 10-K for the year ended December 31, 2024. 10 6. Debt Obligations Oxford Term Loans Overview. Lexicon and one of its subsidiaries entered into a loan and security agreement (the “Loan Agreement”) with Oxford Finance LLC and the lenders listed therein (“Oxford”) in March 2022 (as subsequently amended) that originally provided up to $ 150 million in borrowing capacity (the “Oxford Term Loans”). The Oxford Term Loans are available in five tranches, each maturing in March 2029. The first two $ 25 million tranches totaling $ 50 million were funded in 2022 and the third $ 50 million tranche was funded in June 2023. Availability of the fourth $ 25 million tranche expired on April 15, 2025. 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 with a current amortization date of May 1, 2027. In March 2025, the Company entered into a seventh amendment to the loan and security agreement (the “Seventh Amendment”) with Oxford (a) providing for a prepayment to the lenders of $ 45 million, which occurred in April 2025, and certain additional contingent future prepayments totaling $ 8 million, (b) modifying the amortization date and repayment amortization schedule under the loans under certain circumstances, (c) modifying the financial covenant relating to minimum cash as further described below and (d) eliminating the previous financial covenant relating to net sales of INPEFA ® (sotagliflozin), as well as certain other terms. Interest, Principal Payments, and Carrying Value of Debt. Monthly interest-only payments are due during an initial 60-month period from the original March 2022 borrowing date. The interest-only period will be followed by an amortization period extending through the maturity date. 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 tranche. As of March 31, 2025, the weighted average interest rate of the Oxford Term Loans was 11.9 %. In April 2025 the Company repaid $ 45 million (including final payment exit fees) to Oxford on a pro-rata basis across each loan tranche pursuant to the terms of the Seventh Amendment. Additional payments of $ 20.2 million, $ 30.2 million, and $ 11.6 million, including debt principal and final exit fee payments (equal to 7 % of the remaining amount funded under the Oxford Term Loans), will be due during the fiscal years ended December 31, 2027, December 31, 2028 and December 31, 2029, respectively, with respect to all borrowed loan tranches. As a result of the Seventh Amendment, the current amortization date of May 1, 2027 and the final maturity date of March 1, 2029 are subject to potential acceleration to December 1, 2026 and November 1, 2027, respectively, dependent upon the occurrence of certain future events. Additionally, Lexicon may prepay the Oxford Term Loans in whole at its option at any time subject to prepayment fees of up to 3 % which decline over the three years following the funding date of each loan tranche. As of March 31, 2025, the Company reflected the $ 42.1 million of outstanding principal repaid in April 2025 in current maturities of long-term debt and the remaining carrying value of the Oxford Term Loans of $ 58.6 million in long-term debt on the condensed consolidated balance sheet. The carrying value above reflect an unamortized discount of $ 6.3 million to the face value of long-term debt related to debt issuance costs, the final payment exit fee, and the warrant fair value described below, which are being amortized into interest and other expense. 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. These warrants reduced the carrying value of long-term debt and are classified as equity instruments in additional paid-in capital on the condensed consolidated balance sheet. For additional information on these warrants refer to the Company’s Annual Report on Form 10-K for the year ended December 31, 2024. Restrictive Provisions/Covenants. Among other restrictive provisions and covenants, the loan and security agreement includes a financial covenant which requires us to maintain a minimum balance of unrestricted cash, cash equivalents. short-term investments, and restricted cash, inclusive of a required minimum amount of $ 29 million to be maintained in a blocked account, in an amount equal to not less than the greater of (a) fifty percent ( 50 %) of the outstanding principal amount of the Oxford Term Loans and (b) the required minimum amount of $ 29 million. The Loan Agreement also contains certain customary representations and warranties, affirmative and negative covenants and events of default applicable to Lexicon and its subsidiaries. In addition to the financial covenant, additional 11 covenants include those restricting dispositions, fundamental changes to its business, mergers or acquisitions, indebtedness, encumbrances, distributions, investments, transactions with affiliates and subordinated debt. If an event of default occurs and is continuing, Oxford may declare all amounts outstanding under the Loan Agreement to be immediately due and payable. 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 Company was in compliance with its debt covenants as of March 31, 2025. 7. Commitments and Contingencies Operating Lease Obligations. Lexicon’s operating leases include leases of office space in The Woodlands, Texas and Bridgewater, New Jersey that will expire in August 2025 and January 2034, respectively. In July 2024, Lexicon entered into a new lease agreement for its existing office space in The Woodlands, Texas. The term of the lease begins September 2025, extends through January 2031 and provides for total undiscounted cash payments of $ 4.1 million. 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 apply this accounting to those leases with terms of twelve months or less. As of March 31, 2025 and December 31, 2024, the right-of-use assets for the office space leases of $ 4.6 million and $ 4.8 million, respectively, are separately included in operating lease right-of-use-assets in the condensed consolidated balance sheet. Current liabilities relating to the leases are included in accrued liabilities in the condensed consolidated balance sheet (as further described in Note 4) and long-term operating lease liabilities of approximately $ 4.5 million and $ 4.6 million, respectively, as of March 31, 2025 and December 31, 2024 are included in other long-term liabilities in the condensed consolidated balance sheet. During each of the three months ended March 31, 2025 and 2024, the Company incurred lease expense of $ 0.4 million. During each of the three months ended March 31, 2025 and 2024, the Company made cash payments for lease liabilities of $ 0.3 million. As of March 31, 2025 and December 31, 2024, the weighted-average remaining lease terms were 8.5 years and 8.6 years, respectively, with weighted-average discount rates of 9.7 % for each year. The following table reconciles the undiscounted cash flows of the operating lease liability to the recorded lease liability at March 31, 2025: (in thousands) 2025 $ 871 2026 865 2027 881 2028 898 2029 914 Thereafter 3,832 Total undiscounted operating lease liability 8,261 Less: amount of lease payments representing interest ( 2,697 ) Present value of future lease payments 5,564 Less: short-term operating lease liability ( 1,044 ) Long-term operating lease liability $ 4,520 Legal Proceedings. Lexicon is from time to time party to claims and legal proceedings that arise in the normal course of its business and that it believes will not have, individually or in the aggregate, a material adverse effect on its results of operations, financial condition or liquidity. 12 8. Equity Incentive Awards Stock-Based Compensation. The Company has stockholder-approved equity incentive plans that permit the grant of stock options, restricted stock units, and other stock-based awards to employees, directors, and consultants of the Company. Compensation expense related to stock options and restricted stock units (“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 for the three months ended March 31, 2025 and 2024 of $ 3.0 million and $ 4.3 million, 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 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 following weighted-average assumptions were used for stock options granted in the three months ended March 31, 2025 and 2024: Expected Volatility Risk-free Interest Rate Expected Term Dividend Rate Three Months Ended March 31, 2025 Employees (1) — % — % — — % Officers and non-employee directors 115 % 4.3 % 6 — % Three Months Ended March 31, 2024 Employees 96 % 4.3 % 4 — % Officers and non-employee directors 104 % 4.2 % 6 — % (1) For the three months ended March 31, 2025, there were no stock options granted to employees.

Segment Information Lexicon operates as a single reportable segment, primarily focusing on the discovery, development and commercialization of pharmaceutical products for the treatment of human disease. Substantially all of the Company’s revenues have been derived from drug discovery alliances, target validation collaborations for the development and, in some cases, analysis of the physiological effects of genes altered in knockout mice, technology licenses, subscriptions to its databases, product sales, government grants and contracts and compound library sales, as well as from commercial sales of its approved drug product. The chief operating decision maker (“CODM”) is the Company’s chief executive officer (“CEO”). The CEO manages and allocates resources on a total company basis by assessing the overall level of resources available and how to best deploy these resources across research and development projects in line with the Company’s long-term company-wide strategic goals. The CEO evaluates single-segment consolidated financial information against budget for purposes of making operating decisions, planning and forecasting for future periods, and deciding the level of investment in the Company’s various operating activities and other capital allocation activities. The CODM assesses financial performance based on consolidated net income (loss) (as reported on the consolidated statement of comprehensive loss). The CEO also uses consolidated cash and cash equivalents and short-term investments (which can be found on our Consolidated Balance Sheets) as a measure of segment assets for allocating resources.
