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 the intravenous (IV) formulation of TPOXX® (“IV TPOXX®”). Additionally, the contract includes funding from BARDA for advanced development of IV TPOXX®, post-marketing activities for oral and IV TPOXX®, and procurement activities. As of June 30, 2021, 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 of five years, approximately $127.1 million of payments are related to exercised options and up to approximately $423.7 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, including during the base period of performance.
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 20,000 courses 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 advanced development of IV TPOXX®; and payments of approximately $0.6 million for supportive procurement activities. As of June 30, 2021, the Company had received or billed for $11.1 million for the successful delivery of approximately 35,700 courses of oral TPOXX® to the Strategic Stockpile, $3.2 million for the manufacture of IV BDS and $11.0 million for other base period activities. IV BDS is expected to be used for the manufacture of 20,000 courses of IV FDP. The $3.2 million received for the manufacture of IV BDS has been recorded as deferred revenue as of June 30, 2021 and December 31, 2020; such amount is expected to be recognized as revenue when IV TPOXX® containing such IV BDS is delivered to the Strategic Stockpile or placed in vendor-managed inventory.
The options that have been exercised to date provide for payments up to approximately $127.1 million. There are exercised options for the following activities: payments up to $11.2 million for the procurement of raw materials to be used in the manufacture of at least 363,070 courses of oral TPOXX®; payments up to $101.3 million for the delivery of up to 363,070 courses of oral TPOXX®; and payments of up to $14.6 million for funding of post-marketing activities for oral TPOXX®. As of June 30, 2021, the Company has received the following payments in connection with exercised options: $112.5 million was received in connection with deliveries made in 2020 of approximately 363,000 courses of oral TPOXX®; and $6.8 million has been received or billed for in connection with post-marketing activities for oral TPOXX®.
Unexercised options specify potential payments up to approximately $423.7 million in total (if all such options are exercised). There are options for the following activities: payments of up to $337.7 million for the delivery of up to approximately 1,089,000 courses of oral TPOXX® to the Strategic Stockpile; payments of up to $76.8 million for the manufacture of up to 192,000 courses of IV FDP, of which up to $30.7 million of payments would be paid upon 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 approximately $5.6 million for supportive procurement activities.
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 64,000 courses of IV TPOXX®; and three separate IV FDP Options, each providing for 64,000 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). If BARDA decides to only exercise IV BDS Options, then the Company would receive payments up to $30.7 million; alternatively, if BARDA decides to exercise both IV BDS Options and IV FDP Options, then the Company would receive payments up to $76.8 million. 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 64,000 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 June 30, 2021 and 2020, the Company recognized revenues of $0.8 million and $1.4 million, respectively, on an over time basis. For the six months ended June 30, 2021 and 2020, the Company recognized revenue of $1.7 million and $3.5 million, respectively, on an over time basis. In contrast, no revenue was recognized for product delivery, and therefore no revenue was recognized at a point in time, for the three and six months ended June 30, 2021. Revenue recognized for product delivery, and therefore recognized at a point in time, for the three and six months ended June 30, 2020, was $36.2 million.
International Procurement Contracts
On January 13, 2021, the Public Health Agency of Canada ("PHAC") awarded a contract to Meridian Medical Technologies, Inc. (“Meridian,” a Pfizer Company) (the “Contract”) for the purchase of up to approximately $33 million of oral TPOXX® (tecovirimat) within five years. The Contract specifies firm commitments for the cumulative purchase of approximately $17 million of oral TPOXX® by March 31, 2023; the remaining courses under the Contract are targeted for delivery after March 31, 2023 and are subject to option exercise by PHAC.
On April 3, 2020, the Company announced that the Canadian Department of National Defence (“CDND”) awarded a contract (the "Canadian Military Contract") to Meridian, pursuant to which the CDND will purchase up to approximately $14 million of oral TPOXX® over four years. In the second quarter 2020, CDND purchased $2.3 million of oral TPOXX®. The remaining purchases are at the option of the CDND, and are expected to primarily occur after regulatory approval of oral TPOXX® in Canada. Meridian is the CDND's counterparty under the Canadian Military Contract, and SIGA is responsible for manufacture and delivery of any oral TPOXX® purchased thereunder. For the six months ended June 30, 2021, there were no deliveries under this contract.
The PHAC and CDND contract awards were both coordinated between SIGA and Meridian under the international promotion agreement (as amended, the "International Promotion Agreement") that was entered into by the parties on June 3, 2019.
Under the terms of the International Promotion Agreement, 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 has agreed not to commercialize any competing product, as defined in the International Promotion Agreement, in the specified field of use in the Territory. SIGA will retain ownership, intellectual property, distribution and supply rights and regulatory responsibilities in connection with TPOXX®, and, in the United States market, will also retain sales and marketing rights with respect to oral TPOXX®. SIGA’s consent shall be required for the entry into any sales arrangement pursuant to the International Promotion Agreement.
The fee Meridian retains pursuant to the International Promotion Agreement will be a specified percentage of the collected proceeds of sales of oral TPOXX® net of certain expenses, for years in which customer invoiced 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 years in which such net invoiced amounts exceed the specified threshold.
Revenue in connection with international procurement contracts for the delivery of product are recognized at a point in time. During the three and six months ended June 30, 2021, the Company recognized $6.9 million and $10.3 million of revenue, respectively, for delivery to PHAC.
Research Agreements and Grants
The Company has an R&D program for IV TPOXX®. This program is funded by the 19C BARDA Contract and a separate development contract with BARDA ("IV Formulation R&D Contract"). The IV Formulation R&D Contract has a period of performance that terminates in February 2024. As of June 30, 2021, the IV Formulation R&D Contract provides for future aggregate research and development funding of up to approximately $1.0 million. Revenues in connection with the IV Formulation R&D Contract are recognized over time. For the three months ended June 30, 2021 and 2020, the Company recognized $0.3 million and $0.3 million, respectively, under this contract. For the six months ended June 30, 2021 and 2020, the Company recognized revenue of $0.5 million and $0.7 million, respectively, under this contract.
In July 2019, the Company was awarded a multi-year research contract valued at a total of $19.5 million, with an initial award of $12.4 million, from the Department of Defense ("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"). In May 2020, the DoD increased the scope and the contract value to a total of $26 million with current available funding of $23 million. In April 2021, the DoD increased the available funding to the full contractual value of $26 million. The period of performance for this contract, as modified, terminates on April 30, 2024. For the three months ended June 30, 2021 and 2020, the Company, under the PEP Label Expansion R&D Contract, recognized revenue of $0.5 million and less than $0.1 million, respectively, on an over time basis. For the six months ended June 30, 2021 and 2020, the Company, under the PEP Label Expansion R&D Contract, recognized revenue of $0.6 million and of less than $0.1 million, respectively, on an over time basis.
On May 13, 2011, the Company signed a contract with BARDA ("2011 BARDA Contract") pursuant to which BARDA agreed to buy from the Company 1.7 million courses of oral TPOXX®. Additionally, the Company agreed to contribute to BARDA 300,000 courses at no additional cost to BARDA.
The 2011 BARDA Contract specifies approximately $508.4 million of payments, of which, as of June 30, 2021, $459.8 million has been received by the Company for the manufacture and delivery of 1.7 million courses of oral TPOXX® and $45.8 million has been received for certain reimbursements in connection with development and supportive activities. Approximately $2.8 million remains eligible to be received in the future for reimbursements of development and supportive activities.
The 2011 BARDA Contract expires in December 2024.
Remaining performance obligations under the 2011 BARDA Contract generate revenue over time. For the three months ended June 30, 2021 and 2020, the Company recognized revenue of less than $0.1 million and approximately $0.1 million, respectively, on an over time basis. For the six months ended June 30, 2021 and 2020, the Company recognized revenue of $0.1 million and $0.1 million, respectively, 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.
