Debt Disclosure [Abstract] |
Debt Obligations | 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 2023. Availability of the fourth $25 million tranche expired in April 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 September 30, 2025, the weighted average interest rate of the Oxford Term Loans was 11.8%. In April 2025, the Company repaid $45 million (including pro-rata 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 which have declined to 1 percent on a portion of the outstanding amounts of each loan tranche. As of September 30, 2025, the Company reflected the carrying value of the Oxford Term Loans of $56.5 million in long-term debt on the condensed consolidated balance sheet. The carrying value above reflects an unamortized discount of $5.5 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. As of September 30, 2025, the Company reflected the $29 million minimum cash in the blocked account as restricted cash on the condensed consolidated balance sheet. 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 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 September 30, 2025.
