Procurement Contract and Research Agreements [Text Block] | 3. Procurement Contracts and Research Agreements 19C BARDA Contract On September 10, 2018, the Company entered into a contract with the U.S. Biomedical Advanced Research and Development Authority ("BARDA") pursuant to which SIGA agreed to deliver up to 1,488,000 courses of oral TPOXX® to the U.S. Strategic National Stockpile ("Strategic Stockpile"), and to manufacture and deliver to the Strategic Stockpile, or store as vendor-managed inventory, up to 212,000 courses of IV TPOXX®. In October 2023, the contract was modified so that a course of IV TPOXX® was redefined within the contract from being 14 vials to being 28 vials; as such, the 19C BARDA Contract currently specifies 106,000 courses of IV TPOXX® (for the same payment amount as originally specified). In addition to the delivery of TPOXX® courses, the contract includes funding from BARDA for a range of activities, including: advanced development of IV TPOXX®, post-marketing activities for oral and IV TPOXX®, and procurement activities. As of March 31, 2024, the contract with BARDA (as amended, modified, or supplemented from time to time, the "19C BARDA Contract") contemplates up to approximately $602.5 million of payments, of which approximately $51.7 million of payments are included within the base period of performance, approximately $407.1 million of payments are related to exercised options, and up to approximately $143.7 million of payments are currently specified as unexercised options. BARDA may choose in its sole discretion when, or whether, to exercise any of the unexercised options. The period of performance for options is up to ten years from the date of entry into the 19C BARDA Contract and such options could be exercised at any time during the contract term. The base period of performance specifies potential payments of approximately $51.7 million for the following activities: payments of approximately $11.1 million for the delivery of approximately 35,700 courses of oral TPOXX® to the Strategic Stockpile; payments of $8.0 million for the manufacture of 10,000 courses (as currently defined within the contract as being 28 vials) of final drug product of IV TPOXX® ("IV FDP"), of which $3.2 million of payments are related to the manufacture of bulk drug substance ("IV BDS") to be used in the manufacture of IV FDP; payments of approximately $32.0 million to fund reimbursed activities; and payments of approximately $0.6 million for supportive procurement activities. As of March 31, 2024, the Company had received $11.1 million for the delivery of approximately 35,700 courses of oral TPOXX® to the Strategic Stockpile, $3.2 million for the manufacture of IV BDS, $4.3 million for the delivery of IV FDP to the Strategic Stockpile and $23.0 million for other base period activities. IV BDS has been used for the manufacture of courses of IV FDP. The $3.2 million received for the completed manufacture of IV BDS had been recorded as deferred revenue as of December 31, 2021, but with the delivery of IV FDP to the Strategic Stockpile during 2022, $2.9 million was recognized as revenue. The remaining $0.3 million of deferred revenue will be recognized as IV FDP containing such IV BDS is delivered to and accepted by the Strategic Stockpile. The options that have been exercised as of March 31, 2024, provide for payments up to approximately $407.1 million. As of March 31, 2024, there are exercised options for the following activities: payments up to $337.7 million for the manufacture and delivery of up to 1.1 million courses of oral TPOXX®; payments up to $51.2 million for the manufacture of courses of IV FDP, of which $20.5 million of payments relate to the manufacture of IV BDS to be used in the manufacture of IV FDP; payments of up to approximately $3.6 million to fund post-marketing activities for IV TPOXX®; and payments of up to $14.6 million for funding of post-marketing activities for oral TPOXX®. As of March 31, 2024, the Company has cumulatively delivered $337.7 million of oral TPOXX® to the Strategic Stockpile, of which approximately $15 million was delivered in the first quarter of 2024; has cumulatively received $20.5 million for the completed manufacture of IV BDS, of which $20.5 million has been recorded as deferred revenue as of March 31, 2024; and has been cumulatively reimbursed $8.2 million in connection with post-marketing activities for oral and IV TPOXX®. Unexercised options specify potential payments up to approximately $143.7 million in total (if all such options are exercised), of which approximately $5.6 million relates to supportive activities that we currently do not expect to be required. The remaining unexercised options specify potential payments for the following activities: payments of up to $112.5 million for the delivery of oral TPOXX® to the Strategic Stockpile; and payments of up to $25.6 million for the manufacture of courses of IV FDP, of which up to $10.2 million of payments would be paid upon the manufacture of IV BDS to be used in the manufacture of IV FDP. The options related to IV TPOXX® are divided into two primary manufacturing steps. There are options related to the manufacture of bulk drug substance (“IV BDS Options”), and there are corresponding options (for the same number of IV courses) for the manufacture of final drug product (“IV FDP Options”). BARDA may choose to exercise any, all, or none of these options in its sole discretion. The 19C BARDA Contract includes: three separate IV BDS Options, each providing for the bulk drug substance equivalent of 32,000 courses (as currently defined within the contract) of IV TPOXX®; and three separate IV FDP Options, each providing for 32,000 courses of final drug product of IV TPOXX®. BARDA has the sole discretion as to whether to simultaneously exercise IV BDS Options and IV FDP Options, or whether to exercise options at different points in time (or alternatively, to only exercise the IV BDS Option but not the IV FDP Option). To date, BARDA has exercised two of the three IV BDS options and two of the three IV FDP options. If BARDA decides only to exercise the remaining IV BDS Option, then the Company would receive payments up to $10.2 million; alternatively, if BARDA decides to exercise the remaining IV BDS Option and IV FDP Option, then the Company would receive payments up to $25.6 million. BARDA may also decide not to exercise either remaining option. For each set of options relating to a specific group of courses (for instance, the IV BDS and IV FDP options that reference the same 32,000 courses), BARDA has the option to independently purchase IV BDS or IV FDP. Revenues in connection with the 19C BARDA Contract are recognized either over time or at a point in time. Performance obligations related to product delivery generate revenue at a point in time. Revenue from other performance obligations under the 19C BARDA Contract are recognized over time using an input method using costs incurred to date relative to total estimated costs at completion. For the three months ended March 31, 2024 and 2023, the Company recognized revenues of $1.6 million and $1.6 million, respectively, on an over time basis. In contrast, revenue recognized for product delivery, and therefore at a point in time, for the three months ended March 31, 2024 was $14.7 million. No revenue was recognized for product delivery, and therefore no revenue was recognized at a point in time, for three months ended March 31, 2023. U.S. Department of Defense Procurement Contracts On May 12, 2022, the Company announced a contract with the U.S. Department of Defense ("DoD") for the procurement of oral TPOXX® ("DoD Contract #1"). The DoD Contract #1 included a firm commitment for the DoD to procure approximately $3.6 million of oral TPOXX®, and an option, exercisable at the sole discretion of the DoD, for the procurement of an additional approximately $3.8 million of oral TPOXX®. In the second quarter of 2022, the Company delivered oral TPOXX® to the DoD and recognized revenue of $3.6 million, fulfilling the firm commitment in DoD Contract #1. In the third quarter of 2022, the DoD exercised the option for $3.8 million of oral TPOXX® and the Company satisfied its obligation by delivering product in September 2022 and recognized the related revenue. On September 28, 2022, the Company and the DoD signed a new procurement contract ("DoD Contract #2"). The DoD Contract #2 included a firm commitment for the DoD to procure approximately $5.1 million of oral TPOXX®, and an option, exercisable at the sole discretion of the DoD for the procurement of an additional approximately $5.5 million of oral TPOXX®. In March 2023, the Company fulfilled the firm commitment by delivering $5.1 million of oral TPOXX® to the DoD, and recognized the related revenue. Additionally, in March 2023, the DoD exercised the $5.5 million option in DoD Contract #2 for the procurement of oral TPOXX® and the Company delivered these courses to the DoD in the fourth quarter of 2023 and recognized the related revenue. In February 2024, DoD Contract #2 was amended and approximately $1 million of oral TPOXX® was ordered by the DoD, with delivery fulfilled in the first quarter of 2024. International Procurement Contracts In the first quarter of 2024, the Company delivered approximately $7 million of oral TPOXX® to seven European countries, substantially completing deliveries under the $18 million of firm commitment orders from 13 countries under the European Commission’s DG HERA (Health Emergency Preparedness and Response Authority) joint procurement mechanism, which was announced by the Company in October 2022. Additionally, $0.7 million of oral TPOXX® was delivered to the Canada Department of National Defence ("CDND") in the first quarter of 2024. These deliveries were made in connection with orders and contracts under the International Promotion Agreement (defined and discussed below). Through the International Promotion Agreement, Meridian is the counterparty to international contracts under which orders are placed for the purchase of oral TPOXX®. In addition to the above-mentioned orders and deliveries, the Company has a contract with the CDND under which the CDND has an option until December 31, 2025, exercisable at its sole discretion, for the purchase of up to an additional $6.7 million of oral TPOXX®. As an international contract, this contract is also administered under the International Promotion Agreement. The contract with the CDND (the "Canadian Military Contract"), issued in April of 2020 and subsequently amended, is option-based and initially specified that the CDND would purchase up to $14 million of oral TPOXX® if all options were exercised. Under the International Promotion Agreement, Meridian is the counterparty in connection with international contracts for oral TPOXX® and SIGA is responsible for manufacture and delivery of any oral TPOXX® purchased thereunder. Under the terms of the International Promotion Agreement, which has an initial term that expires on May 31, 2024, Meridian was granted exclusive rights to market, advertise, promote, offer for sale, or sell oral TPOXX® in a field of use specified in the International Promotion Agreement in all geographic regions except for the United States (the “Territory”), and Meridian agreed not to commercialize any competing product, as defined in the International Promotion Agreement, in the specified field of use in the Territory. SIGA retains ownership, intellectual property, distribution and supply rights and regulatory responsibilities in connection with TPOXX®, and, in the United States market, also retains sales and marketing rights with respect to oral TPOXX®. SIGA’s consent is required prior to the entry by Meridian into any sales arrangement pursuant to the International Promotion Agreement. Sales to international customers pursuant to the International Promotion Agreement are invoiced and collected by Meridian, and such collections are remitted, less Meridian's fees, to the Company under a quarterly process specified in the International Promotion Agreement. The fee Meridian retains pursuant to the International Promotion Agreement is a specified percentage of the collected proceeds of sales of oral TPOXX®, net of certain expenses, for calendar years in which customer collected amounts net of such expenses are less than or equal to a specified threshold, and a higher specified percentage of such collected net proceeds for calendar years in which such net collected amounts exceed the specified threshold. On March 27, 2024, SIGA and Meridian entered into an amendment (the “Amendment”) to the International Promotion Agreement. The changes to the International Promotion Agreement contemplated by the Amendment are effective as of June 1, 2024. Under the terms of the International Promotion Agreement, as amended (the “Amended International Promotion Agreement”), the Company will assume primary responsibility for the advertising, promotion and sale of oral TPOXX® in all geographic regions. Meridian will retain limited, non-exclusive rights to continue to advertise, promote, offer for sale and sell oral TPOXX® in the European Economic Area, Australia, Japan, Switzerland and the United Kingdom (collectively, the “New Territory”). Meridian will also continue to perform non-promotional activities under specified existing contracts with third parties providing for the sale of oral TPOXX®. The Amended International Promotion Agreement provides that Meridian is entitled to receive a reduced promotion fee equal to a high single digit percentage of collected proceeds (whether collected by Meridian or the Company), net of certain expenses, of sales of oral TPOXX® in the New Territory in the field of use specified in the Amended International Promotion Agreement. The Amended International Promotion Agreement has a fixed term that expires on May 31, 2026, with no automatic renewal. Revenue in connection with international procurement contracts for the delivery of product are recognized at a point in time on a gross basis, as the Company acts as the principal in the transaction. During the three months ended March 31, 2024, the Company recognized approximately $8.0 million of sales in connection with international contracts. During the three months ended March 31, 2023, the Company did not recognize any revenue related to international contracts. Research Agreements and Grants In July 2019, the Company was awarded a multi-year research contract ultimately valued at approximately $27 million from the DoD to support work in pursuit of a potential label expansion for oral TPOXX® that would include post-exposure prophylaxis ("PEP") of smallpox (such work known as the "PEP Label Expansion Program" and the contract referred to as the "PEP Label Expansion R&D Contract"). As of December 31, 2023, the Company invoiced the full amount of available funding, and there is no remaining revenue to be recognized in the future under the PEP Label Expansion R&D Contract. Revenue from the performance obligation under the PEP Label Expansion R&D Contract was recognized over time using an input method using costs incurred to date relative to total estimated costs at completion. The Company did not recognize any revenue for the three months ended March 31, 2024 related to the PEP Label Expansion R&D Contract. For the three months ended March 31, 2023, the Company, under the PEP Label Expansion R&D Contract, recognized revenue of $1.4 million on an over time basis. Contracts and grants include, among other things, options that may or may not be exercised at the U.S. Government’s discretion. Moreover, contracts and grants contain customary terms and conditions including the U.S. Government’s right to terminate or restructure a contract or grant for convenience at any time. As such, the Company may not be eligible to receive all available funds.
