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 the intravenous (IV) formulation of TPOXX® (“IV TPOXX®”). Additionally, 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 September 30, 2022, 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 $268.9 million of payments are related to exercised options and up to approximately $281.9 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 September 30, 2022, the Company has 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 $17.1 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 the nine months ended September 30, 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 the Strategic Stockpile. The options that have been exercised to date provide for payments up to approximately $268.9 million. There are exercised options for the following activities: payments up to $11.2 million for the procurement of raw materials used in the 2020 manufacture of certain courses of oral TPOXX®; payments up to $213.9 million for the delivery of up to 726,140 courses of oral TPOXX®; payments up to $25.6 million for the manufacture of courses of IV FDP, of which $10.2 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 September 30, 2022, the Company has received $225.1 million for the delivery (and related procurement of raw materials) of oral TPOXX® to the Strategic Stockpile; received $10.2 million for the completed manufacture of IV BDS, which has been recorded as deferred revenue as of September 30, 2022; and received or billed $8.1 million in connection with post-marketing activities for oral TPOXX®. Unexercised options specify potential payments up to approximately $281.9 million in total (if all such options are exercised). There are options for the following activities: payments of up to $225.1 million for the delivery of oral TPOXX® to the Strategic Stockpile; payments of up to $51.2 million for the manufacture of courses of IV FDP, of which up to $20.5 million of payments would be paid upon the manufacture of IV BDS to be used in the manufacture of IV FDP; 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). To date, BARDA has exercised one of the three IV BDS options and one of the three IV FDP options, both of which were exercised simultaneously in 2022. If BARDA decides to only exercise the remaining IV BDS Options, then the Company would receive payments up to $20.5 million; alternatively, if BARDA decides to exercise all the remaining IV BDS Options and IV FDP Options, then the Company would receive payments up to $51.2 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 September 30, 2022 and 2021, the Company recognized revenues of $2.7 million and $1.1 million, respectively, on an over time basis. For the nine months ended September 30, 2022 and 2021, the Company recognized revenues of $4.6 million and $2.8 million, respectively, on an over time basis. Revenue recognized for product delivery, and therefore at a point in time, for the nine months ended September 30, 2022 was $7.2 million. In contrast, no revenue was recognized for product delivery, and therefore no revenue was recognized at a point in time, for the three months ended September 30, 2022 or for the three and nine months ended September 30, 2021. *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 approximately $3.8 million of oral TPOXX®. In the second quarter of 2022, the Company delivered and recognized revenue of $3.6 million for the delivery of oral TPOXX® to the DoD, 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 and recognized the related revenue in September 2022. On September 28, 2022, the Company and the DoD signed a new procurement contract ("DoD Contract #2"). The DoD Contract #2 includes a firm commitment for the DoD to procure approximately $5.2 million of oral TPOXX®, and an option, exercisable at the sole discretion of the DoD for the procurement of approximately $5.5 million of oral TPOXX®. International Procurement Contracts This year, through October 31, 2022, the Company has received firm commitment orders from 13 international customers (including Canada) for the delivery of approximately $77 million of oral TPOXX®, of which approximately $39 million is for Canada and approximately $38 million is for jurisdictions in Europe, Asia-Pacific, and the Middle East. Additionally, the contract with CDND (defined below) has an option until March 31, 2024, exercisable at the sole discretion of CDND, for the purchase of up to an additional $6 million of oral TPOXX®. With respect to the $77 million of firm commitment orders that have been received this year, approximately $66 million of oral TPOXX® was delivered and recorded as revenue in the nine months ended September 30, 2022. Through an International Promotion Agreement (defined below), Meridian Medical Technologies, Inc. (“Meridian”) is the counterparty to international contracts under which orders are placed for the purchase of oral TPOXX®. The Public Health Agency of Canada (“PHAC”) and the Canadian Department of National Defence (“CDND”) are among the contracting parties for the purchase of oral TPOXX® (see below for a summary description of these contracts). On January 13, 2021, PHAC awarded a contract to Meridian (the “PHAC Contract”) for the purchase of up to approximately $33 million of oral TPOXX® (tecovirimat) within five years. In March 2022 and July 2022, PHAC executed amendments in which total procurement of oral TPOXX® under the PHAC Contract was increased to an amount of approximately $45 million. Prior to 2022, approximately $10 million of oral TPOXX® had been ordered and delivered to PHAC. No courses of oral TPOXX® were delivered under this contract for the first six months of 2022. During the three months ended September 30, 2022, approximately $35 million of oral TPOXX® was delivered to PHAC and recognized as revenue. Including the deliveries in the third quarter of 2022, there are no current remaining amounts specified in the PHAC Contract. On April 3, 2020, the Company announced that the CDND awarded a contract (the "Canadian Military Contract") to Meridian, pursuant to which the CDND would purchase up to approximately $14 million of oral TPOXX® over four years. Prior to 2022, approximately $4 million of oral TPOXX® had been ordered and delivered to CDND. No courses of oral TPOXX® were delivered under this contract for the first nine months of 2022. As of September 30, 2022, an approximate firm commitment order of $4 million remains to be delivered under this contract. Additionally, there are approximately $6 million of unexercised options, exercisable at the sole discretion of CDND, remaining under this contract. The above-listed contract awards were 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 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, 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 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 for the entry into any sales arrangement pursuant to 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. It is probable that we will exceed the specified threshold in 2022 and, as a result, the Company has recorded and will continue to record the higher specified percentage for all International Promotion Agreement sales in 2022. 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 and nine months ended September 30, 2022, the Company recognized $61.3 million and $66.2 million of sales, respectively, in connection with international contracts. During the three and nine months ended September 30, 2021, the Company recognized $2.3 million and $12.7 million of sales, respectively, for deliveries to PHAC and CDND. *Research Agreements and Grants* 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 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 subsequent modifications, the DoD increased the scope and the available funding under the PEP Label Expansion R&D Contract to approximately $27 million. The period of performance for this contract, as modified, terminates on January 31, 2025. As of September 30, 2022, remaining revenue to be recognized in the future under the PEP Label Expansion R&D Contract is up to $11.2 million. Revenue from the performance obligation under the PEP Label Expansion R&D Contract is recognized over time using an input method using costs incurred to date relative to total estimated costs at completion. For the three months ended September 30, 2022 and 2021, the Company, under the PEP Label Expansion R&D Contract, recognized revenue of $4.2 million and $1.3 million, respectively, on an over time basis. For the nine months ended September 30, 2022 and 2021, the Company, under the PEP Label Expansion R&D Contract, recognized revenue of $13.1 million and $2.0 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.

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 September 30, 2022, the Company has 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 $17.1 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 the nine months ended September 30, 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 the Strategic Stockpile.

The options that have been exercised to date provide for payments up to approximately $268.9 million. There are exercised options for the following activities: payments up to $11.2 million for the procurement of raw materials used in the 2020 manufacture of certain courses of oral TPOXX®; payments up to $213.9 million for the delivery of up to 726,140 courses of oral TPOXX®; payments up to $25.6 million for the manufacture of courses of IV FDP, of which $10.2 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 September 30, 2022, the Company has received $225.1 million for the delivery (and related procurement of raw materials) of oral TPOXX® to the Strategic Stockpile; received $10.2 million for the completed manufacture of IV BDS, which has been recorded as deferred revenue as of September 30, 2022; and received or billed $8.1 million in connection with post-marketing activities for oral TPOXX®.

Unexercised options specify potential payments up to approximately $281.9 million in total (if all such options are exercised). There are options for the following activities: payments of up to $225.1 million for the delivery of oral TPOXX® to the Strategic Stockpile; payments of up to $51.2 million for the manufacture of courses of IV FDP, of which up to $20.5 million of payments would be paid upon the manufacture of IV BDS to be used in the manufacture of IV FDP; 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). To date, BARDA has exercised one of the three IV BDS options and one of the three IV FDP options, both of which were exercised simultaneously in 2022. If BARDA decides to only exercise the remaining IV BDS Options, then the Company would receive payments up to $20.5 million; alternatively, if BARDA decides to exercise all the remaining IV BDS Options and IV FDP Options, then the Company would receive payments up to $51.2 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 September 30, 2022 and 2021, the Company recognized revenues of $2.7 million and $1.1 million, respectively, on an over time basis. For the nine months ended September 30, 2022 and 2021, the Company recognized revenues of $4.6 million and $2.8 million, respectively, on an over time basis. Revenue recognized for product delivery, and therefore at a point in time, for the nine months ended September 30, 2022 was $7.2 million. In contrast, no revenue was recognized for product delivery, and therefore no revenue was recognized at a point in time, for the three months ended September 30, 2022 or for the three and nine months ended September 30, 2021.

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 approximately $3.8 million of oral TPOXX®. In the second quarter of 2022, the Company delivered and recognized revenue of $3.6 million for the delivery of oral TPOXX® to the DoD, 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 and recognized the related revenue in September 2022.

On September 28, 2022, the Company and the DoD signed a new procurement contract ("DoD Contract #2"). The DoD Contract #2 includes a firm commitment for the DoD to procure approximately $5.2 million of oral TPOXX®, and an option, exercisable at the sole discretion of the DoD for the procurement of approximately $5.5 million of oral TPOXX®.

International Procurement Contracts

This year, through October 31, 2022, the Company has received firm commitment orders from 13 international customers (including Canada) for the delivery of approximately $77 million of oral TPOXX®, of which approximately $39 million is for Canada and approximately $38 million is for jurisdictions in Europe, Asia-Pacific, and the Middle East. Additionally, the contract with CDND (defined below) has an option until March 31, 2024, exercisable at the sole discretion of CDND, for the purchase of up to an additional $6 million of oral TPOXX®. With respect to the $77 million of firm commitment orders that have been received this year, approximately $66 million of oral TPOXX® was delivered and recorded as revenue in the nine months ended September 30, 2022. Through an International Promotion Agreement (defined below), Meridian Medical Technologies, Inc. (“Meridian”) is the counterparty to international contracts under which orders are placed for the purchase of oral TPOXX®. The Public Health Agency of Canada (“PHAC”) and the Canadian Department of National Defence (“CDND”) are among the contracting parties for the purchase of oral TPOXX® (see below for a summary description of these contracts).

On January 13, 2021, PHAC awarded a contract to Meridian (the “PHAC Contract”) for the purchase of up to approximately $33 million of oral TPOXX® (tecovirimat) within five years. In March 2022 and July 2022, PHAC executed amendments in which total procurement of oral TPOXX® under the PHAC Contract was increased to an amount of approximately $45 million. Prior to 2022, approximately $10 million of oral TPOXX® had been ordered and delivered to PHAC. No courses of oral TPOXX® were delivered under this contract for the first six months of 2022. During the three months ended September 30, 2022, approximately $35 million of oral TPOXX® was delivered to PHAC and recognized as revenue. Including the deliveries in the third quarter of 2022, there are no current remaining amounts specified in the PHAC Contract.

On April 3, 2020, the Company announced that the CDND awarded a contract (the "Canadian Military Contract") to Meridian, pursuant to which the CDND would purchase up to approximately $14 million of oral TPOXX® over four years. Prior to 2022, approximately $4 million of oral TPOXX® had been ordered and delivered to CDND. No courses of oral TPOXX® were delivered under this contract for the first nine months of 2022. As of September 30, 2022, an approximate firm commitment order of $4 million remains to be delivered under this contract. Additionally, there are approximately $6 million of unexercised options, exercisable at the sole discretion of CDND, remaining under this contract.

The above-listed contract awards were 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 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, 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 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 for the entry into any sales arrangement pursuant to 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. It is probable that we will exceed the specified threshold in 2022 and, as a result, the Company has recorded and will continue to record the higher specified percentage for all International Promotion Agreement sales in 2022.

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 and nine months ended September 30, 2022, the Company recognized $61.3 million and $66.2 million of sales, respectively, in connection with international contracts. During the three and nine months ended September 30, 2021, the Company recognized $2.3 million and $12.7 million of sales, respectively, for deliveries to PHAC and CDND.

Research Agreements and Grants

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 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 subsequent modifications, the DoD increased the scope and the available funding under the PEP Label Expansion R&D Contract to approximately $27 million. The period of performance for this contract, as modified, terminates on January 31, 2025. As of September 30, 2022, remaining revenue to be recognized in the future under the PEP Label Expansion R&D Contract is up to $11.2 million. Revenue from the performance obligation under the PEP Label Expansion R&D Contract is recognized over time using an input method using costs incurred to date relative to total estimated costs at completion. For the three months ended September 30, 2022 and 2021, the Company, under the PEP Label Expansion R&D Contract, recognized revenue of $4.2 million and $1.3 million, respectively, on an over time basis. For the nine months ended September 30, 2022 and 2021, the Company, under the PEP Label Expansion R&D Contract, recognized revenue of $13.1 million and $2.0 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.
