The accompanying unaudited consolidated financial statements have been prepared in accordance with generally accepted accounting principles (“GAAP”) in the U.S. for interim financial information and with the instructions to Form 10-Q and Article 10 of the Securities and Exchange Commission's Regulation S-X. Accordingly, they do not include all of the information and footnotes required by accounting principles generally accepted in the U.S. for complete financial statements. In the opinion of management, all adjustments (consisting of normal recurring accruals) considered necessary for a fair presentation have been included. The accompanying consolidated financial statements and notes thereto should be read in conjunction with the Company’s Annual Report on Form 10-K for the year ended December 31, ~~2017.~~2018. Operating results for the three and ~~nine~~six months ended ~~September~~June 30, ~~2018~~2019 are not necessarily indicative of the results that may be expected for the year ending December 31, ~~2018.~~2019.

~~In May 2014, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) No. 2014-09,~~ ~~Revenue from Contracts with Customers (Topic 606),~~ supplemented with a number of subsequent amendments issued by the FASB and collectively referred to herein as “Topic 606”. This guidance supersedes the revenue recognition requirements in Topic 605 ~~Revenue Recognition~~ (“Topic 605”) and requires entities to recognize revenues when control of promised goods or services is transferred to customers at an amount that reflects the consideration to which the entity expects to be entitled to in

During the preparation of the consolidated financial statements for ~~those goods~~the year ended December 31, 2018, management revised the presentation of certain regulatory fees between research and development expenses and selling, general and administrative expenses. As a result, the Company also made revisions to its prior period interim consolidated statements of operations as follows:

These revisions had no impact on the Company’s total operating expenses or ~~services.~~ net loss. The revisions also had no impact on the consolidated balance sheets or the consolidated statements of comprehensive loss, stockholders’ equity or cash flows. Management evaluated the materiality of the revisions from a quantitative and qualitative perspective and concluded that the revisions are immaterial to the consolidated financial statements.

The Company adopted Financial Accounting Standards Board (“FASB”) Accounting Standards Update (“ASU”) No. 2016-02 Leases (“Topic ~~606~~842”) effective January 1, 2019, electing the package of practical expedients and applying the transition provisions as of ~~January 1, 2018 using~~ the ~~modified retrospective transition method.Results for reporting~~effective date. Reporting periods beginning on or after January 1, ~~2018~~2019 are presented under Topic ~~606,~~842, while prior period amounts, as reported under previous GAAP, were not adjusted. ~~The cumulative effects~~As of December 31, 2018, the Company had non-cancellable operating leases for its corporate headquarters facility in Ewing, New Jersey, and its office, research and development facility in Plymouth, Minnesota, a suburb of Minneapolis, which were not required to be recorded on the balance sheet. As a result of the adoption of ~~the new standard were not material to~~Topic 842, the Company recognized approximately $1.0 million in right-of-use assets and lease liabilities in connection with its existing operating leases. The adoption of Topic 842 on January 1, 2019 did not have a significant impact on the Company’s consolidated results of operations or cash flows.

In 2016, the FASB issued ASU 2016-13, Financial Instruments - Credit Losses (Topic 326), Measurement of Credit Losses on Financial Instruments. The amendment in this update replaces the incurred loss impairment methodology in current GAAP with a methodology that reflects expected credit losses on instruments within its scope, including trade receivables. This update is intended to provide financial statement users with more decision-useful information about the expected credit losses. This ASU is effective for annual periods and interim periods for those annual periods beginning after December 15, 2019. The Company is currently evaluating the impact the adoption of ASU 2016-13 will have on its consolidated financial statements. In addition, the difference between the amount of revenue recognized for the three and nine months ended September 30, 2018 under Topic 606 as compared to the amount of revenue that would have been recognized under Topic 605 is not material. See ~~Revenue Recognition~~ ~~below for additional information about the Company’s revenue recognition policy in accordance with Topic 606.~~

In ~~May 2017,~~2018, the FASB issued ~~ASU No. 2017-05,~~ ~~Other Income – Gains~~new guidance on a customer's accounting for implementation, set-up, and ~~Losses from~~other upfront costs incurred in a cloud computing arrangement that is hosted by the ~~Derecognition of Nonfinancial Assets (Subtopic 610-20): Clarifying~~vendor (i.e., a service contract).

In ~~May 2017,~~2018, the FASB issued ~~ASU No. 2017-09,~~ ~~Compensation – Stock Compensation (Topic 718): Scope~~new guidance to clarify the interaction between Collaborative Arrangements and Revenue from Contracts with Customers standards.

The Company does not expect the adoption of ~~ASU 2017-09 did not~~this standard to have a ~~significant~~material impact on ~~the Company’s~~its consolidated financial statements.

~~In February 2016, the FASB issued ASU No. 2016-02,~~ ~~Leases (Topic 842)~~ (“ASU 2016-02”). This new standard requires entities to recognize on its balance sheet assets and liabilities associated with the rights and obligations created by leases with terms greater than twelve months. This new standard is effective for annual reporting periods beginning after December 15, 2018, and interim periods within those annual periods. The Company is currently evaluating the impact of ASU 2016-02 on its consolidated financial statements and currently expects that its operating lease commitments will be subject to the new standard and recognized as operating lease liabilities and right-of-use assets NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

From time to time, the Company has invested in U.S. Treasury bills and government agency notes that are classified as held-to-maturity because of the Company’s intent and ability to hold the securities to maturity. Investments with maturities of one year or less are classified as short-term. These securities are carried at their amortized cost and fair value is determined by quoted market prices. At September 30, 2018, the Company had no short-term investments, and at December 31, 2017, the Company’s investments had a carrying value of $4,993, which approximated fair value.

Inventories are stated at the lower of cost or net realizable value. Cost is determined on a first-in, first-out basis. Certain components of the Company’s products are provided by a limited number of vendors, and the Company’s production, assembly, warehousing and distribution operations are outsourced to third-parties where substantially all of the Company’s inventory is located. Disruption of supply from key vendors or third-party suppliers may have a material adverse impact on the Company’s operations. The Company provides a reserve for potentially excess, dated or obsolete inventories based on an analysis of inventory on hand compared to forecasts of future sales, which was ~~$352~~$1,200 and ~~$510~~$847 at ~~September~~June 30, ~~2018~~2019 and December 31, ~~2017,~~2018, respectively. Inventories consist of the following:

Equipment, molds, furniture, and fixtures are stated at cost, net of accumulated depreciation, and are depreciated using the straight-line method over their estimated useful lives ranging from three to ten years. As of ~~September~~June 30, ~~2018~~2019 and December 31, ~~2017,~~2018, the Company’s equipment, molds, furniture and fixtures totaled ~~$15,325~~$14,994 and ~~$16,158,~~$14,895, respectively, which is presented net of accumulated depreciation of ~~$6,820~~$8,633 and ~~$5,445~~$7,570 as of ~~September~~June 30, ~~2018~~2019 and December 31, ~~2017, respectively. Depreciation expense was $1,376 and $1,068 for the nine months ended September 30,~~ 2018, ~~and 2017,~~ respectively.

The ~~carrying~~Company recognizes right-of-use (“ROU”) assets and lease liabilities when it obtains the right to control an asset under a leasing arrangement with an initial term greater than twelve months. The Company evaluates the nature of each lease at the inception of an arrangement to determine whether it is an operating or financing lease and recognizes the right-of-use asset and lease liabilities based on the present value of future minimum lease payments over the expected lease term. The Company’s leases do not generally contain an implicit interest rate and therefore the Company uses the incremental borrowing rate it would expect to pay to borrow on a similar collateralized basis over a similar term in order to determine the present value of its lease payments. Certain of the Company’s ~~term loan was $25,059 and $24,858 as of September 30, 2018 and December 31, 2017, respectively, which is presented net of unamortized debt issuance costs. As of September 30, 2018,~~lease arrangements contain renewal options that have not been included in the ~~prime-based variable interest rate was 9.50%.

For contracts that contain lease and non-lease components, the ~~borrowing rates currently available~~Company accounts for ~~loans with similar terms.~~both components as a single lease component. Variable lease payments are expensed as incurred.

The Company generates revenue from proprietary and partnered product sales, license and development activities and royalty arrangements. Revenue is recognized when or as the Company transfers control of the promised goods or services to its customers at the transaction price, which is the amount that reflects the consideration to which it expects to be entitled to in exchange for those goods or services.

At inception of each contract, the Company identifies the goods and services that have been promised to the customer and each of those that represent a distinct performance obligation, determines the transaction price including any variable consideration, allocates the transaction price to the distinct performance obligations and determines whether control transfers to the customer at a point in time or over time. Variable consideration is included in the transaction price to the extent that it is probable that a significant reversal in the amount of cumulative revenue recognized will not occur when the uncertainty associated with the variable consideration is subsequently resolved. The Company reassesses its reserves for variable consideration at each reporting date and makes adjustments, if necessary, which may affect revenue and earnings in periods in which any such changes become known.

The Company has elected to recognize the cost for freight and shipping activities as fulfilment cost. Amounts billed to customers for shipping and handling are included as part of the transaction price and recognized as revenue when control of underlying goods are transferred to the customer. The related shipping and freight charges incurred by the Company are included in cost of revenue.

The Company sells its proprietary ~~product~~products OTREXUP^® and XYOSTED^® primarily to wholesale ~~pharmaceutical~~and specialty distributors. ~~Product revenue from sales of OTREXUP~~^®Revenue is recognized when control has transferred to the customer, which is typically upon delivery, at the net selling price, which reflects the variable consideration for which reserves and sales allowances are established for estimated returns, wholesale distribution fees, prompt payment discounts, government rebates and chargebacks, plan rebate arrangements and patient discount and support programs.

The determination of certain of these reserves and sales allowances require management to make a number of judgements and estimates to reflect the Company’s best estimate of the ~~product~~transaction price and the amount of consideration to ~~distributors and~~which it believes it is ~~presented net of estimated returns and product sales allowances for wholesaler discounts, prompt pay discounts, chargebacks, rebates and other patient discount programs.~~ ultimately entitled to receive. The ~~Company estimates returns and product sales allowances~~expected value is determined based on unit sales data, contractual terms with customers and third-party payers, historical ~~trends,~~and expected utilization rates, any new or anticipated changes in programs or regulations that would impact the amount of the actual rebates, customer purchasing patterns, product expiration dates and levels of inventory ~~levels remaining~~ in the distribution ~~channel,~~channel. Reserves for prompt payment discounts are recorded as a reduction in accounts receivable. Reserves for returns, rebates and chargebacks, distributor fees and customer co-pay support programs are included within current liabilities in the ~~terms of contracts in place and other known factors or market expectations.~~consolidated balance sheets.

The Company is party to several license, development, supply and distribution arrangements with pharmaceutical partners, under which the Company produces and is the exclusive supplier of certain products, devices and/or components. Revenue is recognized when or as control of the goods transfers to the customer as follows:

The Company is the exclusive supplier of the Makena^® subcutaneous auto injector product to AMAG. Because the product is custom manufactured for AMAG with no alternative use and the Company has a contractual right to payment for performance completed to date, control is continuously transferred to the customer as product is produced pursuant to firm purchase orders. Revenue is recognized over time using the output method based on the contractual selling price and number of units produced. The amount of revenue recognized in excess of the amount shipped/billed to the customer, if any, is recorded as contract assets due to the short-term nature in which the amount is ultimately expected to be billed and collected from the customer.

All other partnered product sales are recognized at the point in time in which control is transferred to the customer, which is typically upon shipment. Sales terms and pricing are governed by the respective supply and distribution agreements, and there is generally no price protection or right of return. Revenue is recognized at the transaction price, which includes the contractual per unit selling price and estimated variable consideration, if any. For example, the Company sells Sumatriptan Injection USP to Teva ~~under a license, supply and distribution agreement. The Company is initially compensated~~ at cost ~~for shipments of product to Teva~~ and is entitled to receive 50 percent of the net profits from commercial sales made by ~~Teva.~~Teva, payable to the Company within 45 days after the end of the quarter in which the commercial sales are made. The Company recognizes revenue, including the estimated variable consideration it expects to receive for contract margin on future commercial sales, upon shipment of the goods to Teva. The estimated variable consideration is recognized at an amount the Company believes is not subject to significant reversal based on historical experience, and is adjusted at each reporting period if the most likely amount of expected consideration changes or becomes fixed.

~~The Company is the exclusive supplier of the Makena~~^® ~~subcutaneous auto injector product to AMAG under a manufacturing agreement. Because the product that the Company produces for AMAG is custom product with no alternative use~~Licensing and the Company has a right to payment for performance completed to date, control is continuously transferred to the customer with respect to the product supply and therefore revenue is recognized at the transaction price as product is manufactured pursuant to firm purchase orders. The amount of revenue recognized in excess of the amount billed to the customer, if any, is recorded in accounts receivable due to the short-term nature in which the amount is ultimately expected to be billed and collected from the customer.Development Revenue

The Company ~~generally contracts with its partners/customers for~~has entered into several license, development and supply arrangements ~~involving highly-customized customer-specific deliverables~~with pharmaceutical partners under which the Company grants a license to its device technology and know-how and provides research and development ~~activities~~services that often ~~span multiple phases of a product lifecycle and include~~involve multiple performance ~~obligations.~~obligations and highly customized deliverables. For such arrangements, the Company identifies each of the promised goods and services within the contract and the distinct performance obligations at inception, and allocates consideration to each performance obligation ~~at inception of the arrangement~~ based on relative standalone selling price, which is generally determined based on the expected cost plus margin.

If the contract includes an enforceable right to payment for performance completed to date and performance obligations are satisfied over time, the Company recognized revenue over the development period using either the input or output method depending on which is most appropriate given the nature of the distinct deliverable. For other contracts that do not contain an enforceable right to payment for performance completed to date, revenue is recognized when control is transferred to the customer. Factors that may indicate that the transfer of control has occurred include the transfer of legal title, transfer of physical possession, the customer has obtained the significant risks and rewards of ownership of the assets and the Company has a present right to payment.

The Company’s typical payment terms for development contracts may include an upfront payment equal to a percentage of the total contract value with the remaining portion to be billed upon completion and transfer of the individual deliverables or satisfaction of the individual performance obligations. The Company records a liability for cash received in advance of performance, which is presented within deferred revenue on the consolidated balance sheet and recognized as revenue when the associated performance obligations have been satisfied. The Company recognized $505 in licensing and development revenue in connection with contract liabilities that were outstanding as of December 31, 2018 and satisfied during the six months ended June 30, 2019.

License fees and milestones received in exchange for the grant of a license to the Company’s functional intellectual property (“IP”) such as patented technology and know-how in connection with a partnered development arrangement are generally recognized at inception of the arrangement, or over the development period depending on the facts and circumstances, as the license is not generally distinct from the non-licensed goods or services to be provided under the contract. Sales or usage based royalties for which the license is the predominant item to which the royalties relate are recognized at the later of when sales or usage occurs. Other forms of variable consideration, such as milestoneMilestone payments that are contingent upon the occurrence of future events, are evaluated and recorded at the most likely amount, and to the extent that it is probable that a significant reversal will not occur when the associated uncertainty is resolved.

~~The Company’s typical payment terms for~~connection with licenses granted under license and development ~~contracts may include an upfront payment equal to~~arrangements with partners. Royalties are based upon a percentage of commercial sales of partnered products with rates ranging from mid-single digit to low double digit and are tiered based on levels of net sales. These sales-based royalties, for which the ~~total contract value with~~license was deemed the ~~remaining portion~~predominant element to ~~be billed upon completion and transfer of~~which the individual deliverables or satisfaction of the individual performance obligations.

Revenues from development contracts and partnered product supply arrangements, other than the product supplied under the AMAG manufacturing agreement described above, are recognized at the point in timeperiod in which the ~~performance obligation is satisfied~~partners’ commercial sales occur. The royalties are generally reported and ~~control~~payable to the Company within 45 to 60 days of the good or service is transferred to the customer.

The Company bases its estimates of royalties earned on actual sales information from its partners when available or estimated prescription sales from external sources and estimated net selling price.

Remaining performance obligations represents the allocation of transaction price of firm orders and development contract deliverables for which work has not been completed or orders fulfilled, and excludes potential purchase orders under ordering-type supply contracts with indefinite delivery or quantity. As of ~~September~~June 30, ~~2018,~~2019, the aggregate value of remaining performance obligations, excluding contracts with an original expected length of one year or less, was ~~$5.6~~$9.9 million. The Company expects to recognize revenue on the remaining performance obligations over the next ~~twelve months.~~three years.

The Company leases its facilities under non-cancellable operating leases. In May 2019, the Company amended its existing lease of the Company’s corporate headquarters in Ewing, New Jersey to extend the lease term for an additional two years. The lease extension period commences on November 1, 2019 and expires on October 31, 2021. In the first quarter of 2019, the Company also entered into a master lease arrangement for a fleet of vehicles for use by its sales force.

As of June 30, 2019, all of the Company’s leasing arrangements are classified as operating leases. Operating lease costs were $330 and $505 for the three and six months ended June 30, 2019. Cash paid for amounts included in the measurement of operating lease liabilities was $538 and $716 for the three and six months ended June 30, 2019. During the six months ended June 30, 2019, operating lease ROU assets obtained in exchange for operating lease obligations were $2,377, including the impact of the lease amendment for the corporate headquarters. As of June 30, 2019, the weighted average discount rate was approximately 9.5% and the weighted average remaining lease term was 2.7 years.

The following table summarizes the Company’s operating lease maturities as of June 30, 2019:

Under the prior leasing standard, future minimum payments under non-cancellable operating leases as of December 31, 2018 were as follows:

In ~~October~~June 2017, the Company entered into ~~an asset purchase~~a loan and security agreement (the ~~“Asset Purchase~~“Loan Agreement”) with ~~Ferring International Center S.A (together~~Hercules Capital, Inc., for a term loan of up to $35.0 million (the “Term Loan”), under which the Company initially borrowed $25.0 million (“Tranche I”.) The amortizing Term Loan is secured by substantially all of the Company’s assets, excluding intellectual property, accrues interest at a prime-based variable rate with ~~Ferring Pharmaceuticals Inc.~~a maximum of 9.5%, provided for payments of interest-only until August 1, 2019 and ~~Ferring B.V. individually and collectively referred to as “Ferring”~~matures on July 1, 2022.

On June 26, 2019, the Company entered into a First Amendment (the “Amendment”) to ~~sell~~ the ~~worldwide rights, including certain assets, related~~Loan Agreement, which increased the aggregate principal amount available under the Term Loan from $35.0 million to $50.0 million. Upon signing of the Amendment, an additional $15.0 million (“Tranche II”) was funded to the ~~needle-free auto injector device product line for a total purchase price~~Company.

The ~~purchase price was agreed~~Company’s option to ~~be paid in four installments consisting~~request additional advances is available between January 1, 2020 and September 15, 2020. The Amendment extended the interest-only payment period of the ~~following:~~Term Loan to August 1, 2021, which may be further extended to August 1, 2022 if the Company achieves a ~~$2.0 million non-refundable upfront payment, which was received upon entry into the Asset Purchase Agreement and the transfer of~~ certain ~~assets; a second installment of $2.75 million received in February 2018 upon delivery of certain documentation and satisfaction of certain conditions primarily related~~loan extension milestone. The Term Loan maturity date remains July 1, 2022, but may be extended to ~~product manufacturing; a third installment of $4.75 million received in May 2018~~July 1, 2024 contingent upon satisfaction of a certain ~~conditions including further document transfer, Ferring’s successful completion~~loan extension milestone.

The Company is required to pay an end of ~~a regulatory audit by a notified body,~~term fee (“End of Term Charge”) equal to 4.25% of Tranche I and ~~a pilot manufacturing run under Ferring’s supervision; and a final installment of $5.0 million to be paid upon Ferring’s receipt~~3.95% of the ~~CE Mark needed to continue to commercialize~~borrowings under Tranche II and Tranche III, payable upon the ~~product in certain territories~~earlier of July 1, 2022 or repayment of the loan.

As of June 30, 2019 and December 31, 2018, the carrying value of the Term Loan was $40,143 and $25,126, respectively, which consisted of the principal amounts outstanding and the ~~final transfer~~End of ~~certain product-related inventory, equipment and agreements~~Term Charge accrual, less unamortized debt issuance costs that are being amortized/accrued to ~~Ferring, which~~interest expense over the ~~Company anticipates may occur by the end of 2018.~~

~~In the fourth quarter of 2017, the Company recognized a gain on sale of assets upon receipt~~term of the ~~$2.0 million non-refundable upfront payment and transfer~~Term Loan using the effective interest method. Future principal payments under the Term Loan, excluding the contractual End of ~~certain manufacturing equipment and patents to Ferring. The second and third installments~~Term Charges, are refundable to Ferring under certain circumstances if completion of the transaction does not occur within a specified timeframe. Given the uncertainty about the payment and refundability of each subsequent milestone, under ASU 2017-05, the gain on the remaining milestone payments will be recognized when it becomes probable that a significant reversal of the gain will not occur, to be reviewed and updated at each reporting period. During the nine months ended September 30, 2018, the Company satisfied certain conditions and received the second and third installments of $2.75 million and $4.75 million, respectively. These cash proceeds received in excess of recognized gain have been recorded as deferred gaindue in the ~~accompanying consolidated balance sheet.~~following periods:

In August 2017, the Company entered into a sales agreement (the “Sales Agreement”) with Cowen and Company, LLC (“Cowen”) under which the Company could offer and sell, from time to time and at its sole discretion, shares of its common stock having an aggregate offering price of up to $30.0 million through Cowen as the Company’s sales agent and/or as principal. Cowen was permitted to sell the common stock through any method deemed an “at the market offering” as defined in Rule 415 of the Securities Act of 1933, as amended (the “ATM Facility”).

During the three months ended June 30, 2019, the Company made no sales of its common stock under the ATM Facility. For the six months ended June 30, 2019, the Company sold 2.3 million shares of common stock under the ATM Facility. The sale of common stock resulted in aggregate gross proceeds of $8.1 million, less sales commission and payment of offering costs, resulting in net offering proceeds to the Company of $7.8 million.

On June 26, 2019, the Company delivered written notice to Cowen that it was terminating its Sales Agreement effective July 6, 2019. With the provision of such notice, the ATM Facility is no longer available for use. The Company sold a total of 4.4 million shares in connection with the ATM Facility, representing gross proceeds of approximately $15.6 million to the Company.

The ~~Company’s 2008~~Company has an Equity Compensation Plan (the “Plan”), which was amended and restated pursuant to stockholder approval on June 13, 2019 in order to increase the number of shares available for issuance under the Plan, extend the term of the Plan and modify certain provisions. The Plan allows for grants in the form of incentive stock options, nonqualified stock options, stock units, stock awards, stock appreciation rights, and other stock-based awards. All of the Company’s officers, directors, employees, consultants and advisors are eligible to receive grants under the Plan. The maximum number of shares authorized for issuance under the ~~amended and restated~~ Plan is ~~32,200~~40.2 million and the maximum number of shares of stock that may be granted to any one employee for qualified performance-based compensation during a calendar year is ~~4,000~~four million shares. Options to purchase shares of common stock are granted at exercise prices not less than 100% of fair market value on the dates of grant. The term of each option is ten years and the options typically vest ~~in quarterly installments~~ over a three-year period with a minimum vesting period of one year. As of ~~September~~June 30, ~~2018,~~2019, the Plan had approximately ~~2,800~~7.5 million shares available for grant. Stock option exercises are satisfied through the issuance of new shares.

~~Stock Options~~The Company’s Board of Directors has also approved a long-term incentive program (“LTIP”), pursuant to which the Company’s senior executives have been awarded stock options, restricted stock units (“RSUs”) and performance stock units (“PSUs”) with targeted values based on values granted to similarly situated senior executives in the Company’s peer group. The stock options have a ten-year term, have an exercise price equal to the closing price of the Company’s common stock on the date of grant, vest in annual installments over three years, and are granted on the same standard terms and conditions as other stock options granted pursuant to the Plan. The RSU awards made to senior executives vest and convert into shares of the Company’s stock in three equal annual installments. The PSU awards vest and convert into shares of the Company’s common stock based on the Company’s attainment of certain performance goals as established by the Company’s Board of Directors over a performance period, which is typically three years.

A portion of the compensation provided to non-employee members of the Company’s Board of Directors is awarded in the form of stock options and RSUs, which vest in full one year from the date of grant and are otherwise granted on the same standard terms and conditions as other awards granted under the Plan.

In October 2017, the Company entered into an asset purchase agreement (the “Asset Purchase Agreement”) with Ferring International Center S.A. (together with Ferring Pharmaceuticals Inc. and Ferring B.V. individually and collectively referred to as ~~follows:~~“Ferring”) to sell the worldwide rights, including certain assets, related to the needle-free auto injector device product line for a total purchase price of $14.5 million. The purchase price was to be paid in four installments consisting of the following: a $2.0 million upfront payment, which was received upon entry into the Asset Purchase Agreement and the transfer of certain assets; a second installment of $2.75 million received upon delivery of certain documentation and satisfaction of certain conditions primarily related to product manufacturing; a third installment of $4.75 million received upon satisfaction of certain conditions, including further document transfer, the successful completion of a regulatory audit by a notified body, and a pilot manufacturing run under Ferring’s supervision; and a final installment of $5.0 million due upon Ferring’s receipt of the CE Mark needed to continue to commercialize the product in certain territories and the final transfer of certain product-related inventory, equipment and agreements to Ferring (the “Completion Date”).

On May 1, 2019, the Company and Ferring entered into the First Amendment of the Asset Purchase Agreement (the “First Amendment”) to extend the term of the agreement to the third anniversary, to provide for the manufacture and delivery of additional product by Antares to Ferring prior to the Completion Date, and to bifurcate the payment of the final installment of the purchase price such that $2.5 million was paid to the Company upon the First Amendment effective date, with the remaining $2.5 million to be paid at the Completion Date, which is expected to occur by the end of 2019. The Company will continue to manufacture and supply needle-free devices until the Completion Date, and will receive payment for devices manufactured and supplied to its partners, and a royalty on net product sales, in accordance with the existing license and supply agreements.

The Company previously recorded the gain on sale of assets as it was determined that, based on the satisfaction of certain conditions and the status of remaining closing requirements, it was probable that a significant reversal of the gain will not occur. The receipt of the $2.5 million in the three months ended June 30, 2019 was recorded as a reduction in the related contract asset balance and a cash inflow from investing activities in the consolidated condensed statement of cash flows.

Basic loss per common share is computed by dividing net loss applicable to common stockholders by the weighted-average number of common shares outstanding for the period. Diluted loss per common share reflects the potential dilution from the exercise or conversion of securities into common stock. Potentially dilutive stock options and other share-based awards excluded from dilutive loss per share because their effect was anti-dilutive totaled ~~17,386~~19,264 and ~~15,085~~17,326 at ~~September~~June 30, 2019 and 2018, ~~and 2017,~~ respectively.

From time to time, the Company may be involved in various legal matters generally incidental to its business. Although the results of litigation and claims cannot be predicted with certainty, after discussion with legal counsel, management is not aware of any matters for which the likelihood of a loss is probable and reasonably estimable and which could have a material impact on its consolidated financial condition, liquidity, or results of operations.

contends that defendants made false and/or misleading statements and/or failed to disclose that: (i) Antares had provided insufficient data to the FDA in connection with the NDA for XYOSTED^TM®; and (ii) accordingly, Antares had overstated the approval prospects for XYOSTED^TM®. On July 27, 2018, the court entered an order appointing Serghei Lungu as lead plaintiff, Pomerantz LLP as lead counsel, and Lite DePalma Greenberg, LLC as liaison counsel for plaintiff. On August 3, 2018, the parties submitted a stipulation and proposed order, setting forth an agreed-upon schedule for responding to the complaint, which the court granted. Pursuant to that order, plaintiff filed a Consolidated Amended Class Action Complaint on October 9, 2018. On November 26, 2018, ~~and~~ defendants ~~intend to file~~filed a motion to ~~dismiss~~dismiss. Plaintiff filed an opposition to the motion on ~~or before November 26, 2018.~~January 10, 2019 and defendants filed a reply in support of their motion on February 25, 2019. On July 2, 2019, the court dismissed the complaint in its entirety without prejudice. On July 29, 2019, plaintiff filed a Consolidated Second Amended Class Action Complaint against the same parties alleging substantially similar claims. The Company believes that the claims in the Smith action lack merit and intends to defend them vigorously.

On January 12, 2018, a stockholder of the Company filed a derivative civil action, captioned Chiru Mackert, derivatively on behalf of Antares Pharma, Inc., v. Robert F. Apple, et al.(“~~Mackert~~”), in the Superior Court of New Jersey Chancery Division, Mercer County (Case No. C-000011-18). On January 17, 2018, another stockholder filed a derivative action in the same court, captioned Vikram Rao, Derivatively on Behalf of Antares Pharma, Inc. v. Robert F. Apple, et al. (“~~Rao~~”) (Case No. C-000004-18). Both complaints name Robert F. Apple, Fred M. Powell, Thomas J. Garrity, Jacques Gonella, Anton Gueth, Leonard S. Jacob, Marvin Samson and Robert P. Roche, Jr. as defendants, and the Company as nominal defendant, and they assert claims for breach of fiduciary duties, unjust enrichment, abuse of control, gross mismanagement, and waste of corporate assets arising from the same facts underlying the Smith securities class action. The plaintiffs seek damages, corporate governance and internal procedure reforms and improvements, restitution, reasonable attorneys’ fees, experts’ fees, costs, and expenses. The parties have filed a stipulation consolidating the two actions and staying the proceedings pending the court’s decision on defendants’ ~~anticipated~~ motion to dismiss the Smith action.

On January 17, 2018, a stockholder of the Company filed a derivative civil action, captioned Robert Clark, Derivatively on Behalf of Antares Pharma, Inc. v. Robert F. Apple, et al. (“Clark”) (Case No. 3:18-cv-00703-MAS-DEA), against Robert F. Apple, Thomas J. Garrity, Jacques Gonella, Leonard S. Jacob, Marvin Samson, Anton G. Gueth and Robert P. Roche, Jr. as defendants, and Company as a nominal defendant. The action was filed in the U.S. District Court for the District of New Jersey and asserts claims for breach of fiduciary duties, unjust enrichment, abuse of control, waste of corporate assets, and a violation of Section 14(a) of the Securities Exchange Act of 1934. This complaint relates to the same facts underlying the Smith securities class action and the other derivative actions. The plaintiff in Clark seeks damages, corporate governance and internal procedure reforms and improvements, reasonable attorneys’ fees, accountants’ and experts’ fees, costs, and expenses. The parties have filed a stipulation staying the action pending the court’s decision on defendants’ ~~anticipated~~ motion to dismiss the Smith action.

On July 1, 2019, the Company entered into a lease agreement (the “Lease”) with Whitewater Properties I, LLC (the “Landlord”) for approximately 75,000 square feet of office, laboratory, manufacturing and warehousing space in the building known as 12500 Whitewater Drive, Minnetonka, Minnesota. The initial term of the Lease is 12 years and the Company may renew the Lease, at its option, for one additional renewal period of three years. The Landlord delivered possession of the premises to the Company on July 1, 2019 (the “Delivery Date”) and payment of rent will commence on January 1, 2020. The annual base rent is $180,372 in year one, $281,160 in year two, and $625,224 in year three, with annual increases of approximately 2% thereafter over the remaining initial lease term. The Company will also pay additional rent for operating expenses, insurance premiums and taxes. The Company is performing the build-out of the premises at the Company’s cost with an allowance provided by the Landlord of up to approximately $1.2 million, to be disbursed over four disbursement periods, all within 36 months after the Delivery Date.

~~Critical Accounting Policies~~

Our management’s discussion and analysis of our results of operations and financial condition is based upon our consolidated financial statements, which have been prepared in accordance with U.S. generally accepted accounting principles (“GAAP”). The preparation of our financial statements in accordance with GAAP requires us to make judgments and estimates that affect the reported amounts of assets, liabilities, revenues and expenses. We have identified certain of our significant accounting policies that we believe to be the most critical to understanding our results of operations and financial condition because they require the most subjective and complex judgments. The following supplements our critical accounting policies, which are fully described under “Management’s Discussion and Analysis of Financial Condition and Results of ~~Operations”~~Operations

During the three and six months ended June 30, 2019, we continued to generate significant growth in our ~~Annual Report on Form 10-K for the year ended December 31, 2017.~~

~~Revenue Recognition~~

~~Effective January 1, 2018, we adopted Accounting Standards Update No. 2014-09,~~ ~~Revenue from Contracts with Customers (Topic 606),~~ ~~as amended (“Topic 606”) using the modified retrospective transition method. This new standard supersedes the former~~product sales and total revenue, ~~recognition requirements~~and to invest in ~~Topic 605 Revenue Recognition~~ ~~(“Topic 605”). Our results~~our commercial infrastructure and research and development activities. We reported net losses of operations for reporting periods beginning on or after January 1, 2018 are presented under Topic 606, while prior period amounts, as reported, are not adjusted. The effects of the adoption of the new standard were not material to our consolidated financial statements,$2.2 million and ~~the difference between the amount of revenue recognized~~$4.5 million for the three months ended ~~September~~June 30, 2019 and 2018, respectively, and net losses of $7.8 million and $10.7 million for the six months ended June 30, 2019 and 2018, respectively. Net loss per share was $0.01 and $0.05 for the three and six months ended June 30, 2019 as compared to $0.03 and $0.07 for the three and six months ended June 30, 2018, ~~under Topic 606~~respectively. Operating results for the three and six months ended June 30, 2019 are not necessarily indicative of the results that may be expected for the year ending December 31, 2019. The following is an analysis and discussion of our operations for the three and six months ended June 30, 2019 as compared to the ~~amount of revenue that would have been recognized under Topic 605 was not material. The following is a summary, and the critical aspects, of our revenue recognition policy under Topic 606.~~same periods in 2018.

Revenues

We generate revenue from proprietary and partnered product sales, license and development activities and royalty arrangements. Revenue is recognized when or as we transfer control of the promised goods or services to our customers in an amount that reflects the consideration to which we expect to be entitled to in exchange for those goods or services.

We enter into contracts with customers and partners that often contain multiple elements such as licensing, development, manufacturing and commercialization components. These arrangements are often complex and we may receive various types of consideration over the life of the arrangement, including: up-front fees, reimbursements for research and development services, milestone payments, payments on product shipments, margin sharing arrangements, license fees and royalties.

In assessing our revenue arrangements, we must identify the contract and consider whether one or more contracts or elements should be combined to form a contract, determine the transaction price including an estimation of any variable consideration we expect to receive under the contract, identify each of our performance obligations or promises of goods or services to the customer, allocate the transaction price to each of the performance obligations, and recognize revenue when or as the performance obligations are satisfied. Each of these steps in the revenue recognition process requires management to make judgements and/or estimates. The most significant judgements and estimates include: the estimation of product returns and sales allowances and other variable consideration such as expected contract margin and royalties. We base these estimates on historical experience and a review of the facts and circumstances that exist as of each reporting date.

~~Results of Operations~~

We reported a net loss of $1.9 million and $5.5 million for the three months ended September 30, 2018 and 2017, respectively, and $12.6 million and $13.0 million for the nine months ended September 30, 2018 and 2017, respectively. Net loss per share was $0.01 for the three months ended September 30, 2018 as compared to $0.03 for the three months ended September 30, 2017, and was $0.08 for both the nine months ended September 30, 2018 and 2017. Operating results for the three and nine months ended September 30, 2018 are not necessarily indicative of the results that may be expected for the year ending December 31, 2018. The following is an analysis and discussion of our operations for the three and nine months ended September 30, 2018 as compared to the same periods in 2017.

~~Revenues~~

Total revenue for the three months ended ~~September~~June 30, 2019 and 2018 ~~and 2017~~ was ~~$17.9~~$28.4 million and ~~$15.1~~$14.2 million, respectively, ~~and was $44.7 million and $40.5 million for the nine months ended September 30, 2018 and 2017, respectively,~~ representing ~~period over period growth~~an increase in total revenue of ~~19% and 11% for the three and nine months ended September 30, 2018, respectively.

The net decrease in OTREXUP~~^®~~sales~~allowances, generated revenue of $9.0 million and $13.8 million for the three and six months ended ~~September~~June 30, 2019, respectively, as compared to $3.8 million and $7.7 million for the three and six months ended June 30, 2018, respectively. The increase in proprietary product sales for the three and six months ended June 30, 2019 as compared to the three and six months ended ~~September 30, 2017 was primarily a result of an increase in plan rebates and other sales allowances.~~

~~For the nine months ended September~~June 30, 2018 ~~we recognized $11.8 million in OTREXUP~~^® ~~sales as compared to $13.1 million for the nine months ended September 30, 2017. Revenue recognized for OTREXUP~~^® ~~sales in the nine months ended September 30, 2018 was driven by an increase in unit sales in comparison to prior year; however, the overall decrease in OTREXUP~~^®~~revenue in comparison to the nine months ended September 30, 2017 was~~were principally attributable to ~~an increase~~sales of XYOSTED^®, which was launched for commercial sale in plan rebates and other sales allowances in 2018, and the recognition of an additional $1.3 million of revenue in the first quarter of 2017 as a result of a change in estimation and recognition method for revenues that were previously deferred. Prior to the first quarter of 2017, due to lack of sufficient sales and returns history, revenue was initially deferred upon shipment to distributors and recognized based on estimated prescriptions dispensed or expiration of customer right of return. We began recognizing revenue upon delivery to distributors, net of estimated returns, in the first quarter of 2017.

~~Auto injector and pen injector devices~~

~~Product~~ sales of auto injector devices were $1.8 million and $1.6 million for the three months ended September 30, 2018 and 2017, respectively, and $7.9 million and $2.2 million for the nine months ended September 30, 2018 and 2017, respectively.

The~~for use with their Epinephrine Injection USP, an increase in sales of ~~auto~~Sumatriptan Injection USP and pen injector devices ~~for the three and nine months ended September 30, 2018 as compared~~ to ~~the same periods in 2017 was primarily attributable to sales of Makena~~^® ~~auto injectors to AMAG, which was approved by the FDA and launched in the U.S. for commercial sale by AMAG in the first quarter of 2018,~~Teva, and sales of ~~pre-commercial~~needle-free devices ~~and components~~ to Teva related to the pen injector programs. Teva’s generic epinephrine auto injector product was approved by the FDA in August 2018 and Teva has indicated it is preparing to launch the generic epinephrine auto injector product in the fourth quarter of 2018.

~~Needle-free injector devices and components~~

Revenue from reusable needle-free injector devices and disposable components was $1.7 million and $0.8 million for the three months ended September 30, 2018 and 2017, respectively, and $4.5 million and $3.1 million for the nine months ended September 30, 2018 and 2017, respectively. These revenues were generated primarily from sales to Ferring, which sells our needle-free injector for use with its hGH products in Europe, Asia and the U.S. In October 2017, we announced the sale of the worldwide rights related to the needle-free auto injector product to Ferring and anticipate that the transaction may be completed by the end of 2018. During the transfer and completion period, weFerring. We will continue to manufacture and supply needle-free devices ~~until~~through the completion date and will receive payment for devices and a royalty on net product sales in accordance with the existing license and supply agreements.

Licensing and development revenue

Licensing and development revenue includes license fees received from partners for the right to use our intellectual property and amounts earned in joint development arrangements with partners under which we perform joint development activities or develop new products on their behalf. Licensing and development revenue was ~~$2.6~~$2.2 million and ~~$1.5~~$1.8 million for the three months ended ~~September~~June 30, ~~2018~~2019 and ~~2017,~~2018, respectively, and ~~$5.6~~$3.2 million and ~~$9.0~~$3.0 million for the ~~nine~~six months ended ~~September~~June 30, ~~2018~~2019 and ~~2017,~~2018, respectively. The ~~increase~~increases in ~~licensing and~~ development revenue recognized for the ~~three-month period~~three and six months ended ~~September~~June 30, ~~2018~~2019 as compared to ~~the same period in 2017~~2018 was ~~principally~~primarily a result of the ~~$2.0 million milestone received from Teva in connection~~ongoing development programs with ~~the FDA approval of Teva’s epinephrine auto injector product in August 2018. The decrease in licensing~~Pfizer and ~~development revenue for the nine-month period ended September 30, 2018 as compared to 2017 was principally a result of a reduction in development activities with AMAG for the Makena~~^® ~~auto injector product, which was approved by the FDA in February 2018 and is now in the commercialization stage.~~Teva.

Royalties

Royalty revenue was ~~$3.7~~$5.6 million and ~~$0.2~~$1.3 million for the three months ended ~~September~~June 30, ~~2018~~2019 and ~~2017,~~2018, respectively, and ~~$5.5~~$9.6 million ~~and $0.8~~versus $1.8 million for the ~~nine~~six months ended ~~September~~June 30, ~~2018~~2019 and ~~2017,~~2018, respectively.

Cost of Revenue and Gross Profit

The following table summarizes our total revenue, cost of revenue and gross profit (in thousands):

Fluctuations in our gross profit and gross profit percentage are driven by our overall revenue mix. Our gross profit was ~~$10.6~~$16.0 million and ~~$6.5~~$7.2 million for the three months ended ~~September~~June 30, ~~2018~~2019 and ~~2017,~~2018, respectively, and ~~$23.3~~$28.3 million and ~~$20.1~~$12.7 million for the ~~nine~~six months ended ~~September~~June 30, ~~2018~~2019 and ~~2017,~~2018, respectively. The increase in our gross profit and gross profit percentage was primarily attributable to ~~an increase~~the significant increases in ~~royalties received from sales of Makena~~^® ~~auto injectors and a $2.0 million license and development milestone received from Teva in connection with the FDA approval of the epinephrine auto injector product, both of~~our royalty revenue, which ~~have~~has no associated ~~costs, offset by a decrease in our product gross profit. Product revenue,~~incremental cost, ~~of sales~~ and ~~gross profit are summarized in the following table (in thousands):~~

~~Product gross profit decreased for the three and nine months ended September 30, 2018 as compared to the same periods in 2017, primarily due to lower net revenue from OTREXUP~~^®~~sales, lower contract margin received from Teva on sales of Sumatriptan Injection USP, and an increase in sales of Makena~~^® ~~auto injectors to AMAG, which have a lower product sales margin than~~ our proprietary ~~products and provide for back-end royalties on net sales made by AMAG. The cost of~~ product ~~sales includes product acquisition costs from third-party manufacturers and internal manufacturing and overhead expenses.~~

sales. Other variations in ~~revenue,~~ cost of revenue and gross profit ~~are~~were attributable to our increase in product revenue, and to our development activities, which fluctuate depending on the mix of development projects in progress and stages of completion in each period. The cost of development revenue consists primarily of direct external costs, some of which may have been previously incurred and deferred. The cost of development revenue in each period was primarily related to revenue recognized under the Teva auto injector and pen injector programs and development activities for the Makena^® ~~auto injector with AMAG.~~

Research and development expenses consist of external costs for clinical studies and analysis activities, design work and prototype development, FDA application fees, personnel costs and other general operating expenses associated with our research and development activities. Research and development expenses were ~~$3.6~~$2.5 million and ~~$3.3~~$3.2 million for the three months ended ~~September~~June 30, ~~2018~~2019 and ~~2017,~~2018, respectively and ~~$10.6~~$4.9 million and ~~$9.5~~$6.1 million for the ~~nine~~six months ended ~~September~~June 30, ~~2018~~2019 and ~~2017,~~2018, respectively. The ~~increase~~decrease in research and development costs on a comparative basis iswas primarily due to ~~additional~~higher spending associated with ~~undisclosed potential new products and post-CRL activities for~~ XYOSTED^TM®,~~which was approved by the FDA on September 28,~~ prior to its approval in 2018.

Selling, general and administrative expenses were ~~$8.3~~$15.1 million and ~~$8.2~~$7.9 million for three months ended ~~September~~June 30, ~~2018~~2019 and ~~2017,~~2018, respectively, and ~~$23.6~~$30.0 million and ~~$23.0~~$16.1 million for the ~~nine~~six months ended ~~September~~June 30, ~~2018~~2019 and ~~2017,~~2018, respectively. The ~~increase~~significant increases in selling, general and administrative expenses ~~was~~were principally attributable to anincremental sales and marketing costs incurred in connection with the recent launch of XYOSTED^®, including the increase in compensation and benefits expense ~~primarily related to annual salary increases and non-cash stock-based compensation, including performance-based awards for executives.~~associated with approximately 50 additional sales representatives hired in late 2018.

At ~~September~~June 30, ~~2018,~~2019, we had cash and cash equivalents of ~~$28.2~~$40.2 million. Our principal liquidity needs are to fund ~~the commercial launch of XYOSTED~~^TM ~~and~~ our ~~ongoing~~product manufacturing, research and development activities and for the payment of other operating expenses. We have not historically generated, and do not currently expect to generate, enough revenue or operating cash flow to ~~sustain~~support or grow our operations and we ~~expect to~~ continue to ~~support our operations~~operate primarily by raising capital. Our primary sources of liquidity are ~~cash receipts from sales,~~ proceeds from equity offerings and debt issuance. We believe that the combination of our current cash and cash equivalents, projected product sales, development revenue milestones and royalties will provide us with sufficient funds to meet our obligations and support operations through at least the next twelve months from the date of this report.

In June 2017, we entered into a loan and security agreement (the “Loan Agreement”) with Hercules Capital, Inc., for a term loan of up to $35.0 million (the “Term Loan”), ~~the proceeds of~~under which ~~are to be used for working capital and general corporate purposes. The first advance of~~we initially borrowed $25.0 million ~~was funded upon execution~~(“Tranche I”.) The amortizing Term Loan is secured by substantially all of the Company’s assets, excluding intellectual property, accrues interest at a prime-based variable rate with a maximum of 9.5%, provided for payment of interest-only until August 1, 2019 and matures on July 1, 2022.

On June 26, 2019, we entered into a First Amendment (the “Amendment”) to the Loan Agreement, ~~in June 2017. Payments~~which increased the aggregate principle amount available under the Term Loan ~~Agreement~~from $35.0 million to $50.0 million. Upon signing of the Amendment, an additional $15.0 million (“Tranche II”) was funded to us, resulting in total principle balance outstanding under the loan of $40.0 million. We may, but are ~~interest only until~~not obligated to, request one or more additional advances of at least $5.0 million, not to exceed $10.0 million in the ~~first principal~~aggregate (“Tranche III”), between January 1, 2020 and September 15, 2020. The Amendment extended the interest-only payment ~~is due on~~period of the Term Loan to August 1, ~~2019, provided that~~2021, which may be further extended to August 1, 2022 if we achieve a certain loan extension milestone. The loan maturity date of the ~~interest only period~~Term Loan remains July 1, 2022, but may be extended to ~~February~~July 1, ~~2020 if the~~2024 contingent upon satisfaction of a certain ~~corporate milestones are achieved. The Loan Agreement also requires us to pay a fee equal to 4.25% of the total original principal amount of all term~~ loan ~~advances, which is due upon repayment of the Term Loan at either maturity or earlier repayment.~~extension milestone.

In August 2017, we entered into a sales agreement (the “Sales Agreement”) with Cowen and Company, LLC (“Cowen”) under which we ~~may~~could offer and sell, from time to time and at our sole discretion, shares of our common stock having an aggregate offering price of up to $30.0 million through Cowen as ~~our~~the sales agent and/or ~~principal~~.as principal. Cowen ~~may~~was permitted to sell the common stock bythrough any method ~~permitted by law~~ deemed ~~to be~~ an “at the market offering” as defined in Rule 415 of the Securities Act of 1933, as ~~amended. We will pay Cowen a commission~~amended (the “ATM Facility”).

There were no sales of ~~3.0% of the gross sales proceeds of any~~ common stock made pursuant to the ATM Facility during the three months ended June 30, 2019. For the six months ended June 30, 2019, we sold ~~through Cowen under the Sales Agreement. We are not obligated to make any sales~~2.3 million shares of ~~our~~ common stock under the ATM Facility. The sale of common stock resulted in aggregate gross proceeds of $8.1 million, less sales commission and payment of offering costs, resulting in net offering proceeds to the Company of $7.8 million.

On June 26, 2019, we delivered written notice to Cowen that we were terminating the Sales Agreement ~~and as~~effective July 6, 2019. With the provision of such notice, the ~~date~~ATM Facility is no longer available for use. The Company sold a total of ~~this report we have not sold any common stock pursuant~~4.4 million shares in connection with the ATM Facility, representing gross proceeds of approximately $15.6 million to the ~~Sales Agreement.~~Company.

Operating cash inflows are generated primarily from product sales, license and development fees and royalties. Operating cash outflows consist principally of expenditures for manufacturing costs, personnel costs, general and administrative expenses, research and development projects, and sales and marketing activities. Fluctuations in cash used in operating activities are primarily a result of the timing of cash receipts and disbursements. Net cash used in operating activities was ~~$10.2~~$11.2 million for the ~~nine~~six months ended ~~September~~June 30, ~~2018~~2019 and ~~$15.5~~$10.1 million for the ~~nine~~six months ended ~~September~~June 30, ~~2017.~~2018. The increase in net cash used in operating activities was primarily driven by ~~our net loss,~~ inventory build, ~~changes~~growth in accounts receivable ~~and deferred revenue,~~ and other changes in operating assets and liabilities due to timing of cash receipts and cash payments.

Net cash provided by investing activities was ~~$11.9~~$1.4 million for the ~~nine~~six months ended ~~September~~June 30, ~~2018~~2019 as compared to ~~net cash used in investing activities of $10.9~~$12.1 million for the ~~nine~~six months ended ~~September~~June 30, ~~2017.~~2018. The net cash provided by investing activities for the six months ended June 30, 2019 included the receipt of $2.5 million in connection with the Ferring Transaction offset by capital expenditures of $1.1 million. The net cash inflow for the ~~nine~~six months ended ~~September~~June 30, 2018 ~~was attributable to~~included the receipt of $7.5 million in connection with the Ferring Transaction and $5.0 million in proceeds from investment maturities, ~~of investments of $5.0 million~~ offset by payments for capital expenditures and patent acquisition costs. The cash outflow for the nine months ended September 30, 2017 was attributable to purchases of investment securities of $10.0 million and payments for capital expenditures and patent acquisition costs.

The net cash ~~flows used in~~flow provided by financing activities was ~~$0.2~~$22.1 million for the ~~nine~~six months ended ~~September~~June 30, ~~2018,~~2019, and consisted of $15.0 million in new debt proceeds received in connection with the Amendment of our Term Loan, $7.8 million in net cash proceeds received from sales of our common stock through the ATM Facility, and $0.5 million proceeds from the exercise of stock options offset by ~~amounts remitted~~$1.1 million paid to taxing authorities in connection with net-share settled stock-based awards for which we withheld shares equivalent to the value of the employees’ ~~minimum statutory~~tax obligation for the applicable income and other employment taxes. ~~Cash~~Net cash provided by financing activities for the ~~nine~~six months ended ~~September~~June 30, ~~2017~~2018 was ~~$26.1~~$0.2 million, which included ~~$25.0 million in~~ proceeds ~~from the issuance of long-term debt and $1.6 million~~ received in connection with the exercise of stock options ~~net of payments for debt issuance costs of $0.3 million and $0.2 million remitted~~offset by amounts paid to taxing authorities ~~in connection with~~for net-share settled equity awards.

~~There have been no changes or material modifications to~~The following table presents our contractual obligations and the related payments, including interest, due by period as ~~presented~~of June 30, 2019 (in thousands):

The preceding discussion and analysis of our results of operations and financial condition is based upon our consolidated financial statements, which have been prepared in accordance with U.S. generally accepted accounting principles (“GAAP”). The preparation of these consolidated financial statements requires us to make judgments and estimates that affect the reported amounts of assets, liabilities, revenues and expenses. We base our estimates on historical experience and on various other factors that we believe are reasonable under the circumstances. Actual results could differ from our estimates, and significant variances could materially impact our financial condition and results of operations.

The accounting policies we believe to be most critical to understanding our results of operations and financial condition related to revenue recognition and inventory valuation, which are fully described in our Annual Report on Form 10-K ~~as of and~~ for the year ended December 31, ~~2017.~~2018.

We do not have any off-balance sheet arrangements, including any arrangements with any structured finance, special purpose or variable interest entities.

~~Our research and development programs consist primarily~~ ~~of clinical, regulatory, formulation development, engineering, device development and commercial development activities for our current products, next generation versions of current products, and new proprietary and partnered products and technologies in development~~. Our internal research and development team works with external consultants, industry experts, physicians and other medical personnel in an effort to drive a robust product development pipeline. We also have a business development team that actively seeks and evaluates product opportunities and business alliances. In addition, our clinical, quality and regulatory teams are committed to verifying and maintaining the safety and efficacy of our products according to regulatory standards enforced by the FDA and other international regulatory bodies~~. The following is a discussion of our significant research and development programs.~~

~~XYOSTED™ (testosterone) injection~~. We developed XYOSTED™ (testosterone enanthate) injection for self-administered weekly injections of testosterone enanthate in a preservative-free formulation indicated for testosterone replacement therapy in adult males for conditions associated with a deficiency or absence of endogenous testosterone. XYOSTED™ was approved by the FDA on September 28, 2018 and is the only FDA approved subcutaneous testosterone enanthate product for once-weekly, at-home self-administration. XYOSTED™ is approved in three dosage strengths, 50 mg, 75 mg and 100 mg.

As a post-marketing requirement, the FDA has asked us to conduct a label comprehension study that assesses patients’ understanding of key risk messages in the Medication Guide for XYOSTED™ and a study of testosterone replacement therapy in pediatric males ages 14 years and older for conditions associated with a deficiency or absence of endogenous testosterone. The label comprehension study must be completed by 2020 and the pediatric study must be completed by the end of 2026. The conduct of these studies will require a dedication of funds and resources.

~~Partnered Development Projects~~. We have entered into license and development agreements and collaboration arrangements with our pharmaceutical partners Teva and Pfizer to conduct research and development activities related to our VIBEX^® disposable pressure assisted auto injectors and our disposable pen injectors to be used in drug/device combination products. The development programs consist of various activities including determination of the device design, development of prototype tooling, production of prototype devices for testing and clinical studies, and development of commercial tooling and assembly equipment. The following is a summary of the development stages for each of the partnered products in development.

~~We, in collaboration with Teva, developed a VIBEX~~^® auto injector device for a product containing epinephrine. Teva was responsible for development work on the drug epinephrine, and we were responsible for development of the device. Teva filed an ANDA for the VIBEX^® ~~epinephrine pen as a generic substitute of Mylan’s branded product, EpiPen~~^®~~, which was as approved by the FDA in August 2018 as a generic drug product with an AB rating, meaning that it is therapeutically equivalent to Mylan, Inc.’s branded products EpiPen~~^® ~~and EpiPen Jr~~^® ~~and therefore, subject to state law, substitutable at the pharmacy. Teva has indicated it is preparing to launch the generic epinephrine auto injector product in the fourth quarter of 2018.~~

~~We designed and produced, under a license, development and supply agreement with Teva, a multi-dose disposable pen injector for use with a generic form of BYETTA~~^® ~~(exenatide injection) for the treatment of diabetes. Teva is working through the U.S. regulatory approval process for its exenatide pen using the ANDA pathway.~~

~~We also designed and produced for Teva another multi-dose disposable pen for a generic form of Forteo~~^® ~~(teriparatide [rDNA origin] injection) for the treatment of osteoporosis. Teva is working through the U.S. regulatory approval process for a generic version of Forteo~~^® (teriparatide [rDNA origin] injection) using the ANDA pathway. Teva and Lilly settled their Paragraph IV patent litigation, the terms of which have not been disclosed. Teva also successfully completed a decentralized procedure registration process in 17 countries in Europe for teriparatide, and is awaiting patent clearance in the EU prior to launch.

~~In August 2018, we entered into a collaboration agreement with Pfizer to develop a combination drug device rescue pen. This rescue pen will utilize the Antares QuickShot~~^® auto injector and an undisclosed Pfizer drug. We will develop the product and Pfizer will be responsible for obtaining FDA approval of the combination product. We intend to enter into a separate supply agreement with Pfizer pursuant to which we will provide fully packaged commercial ready finished product to Pfizer and Pfizer will then be responsible for commercializing the product in the United States, pending FDA approval, for which the Company will receive royalties on net sales.

~~Other Research and Development Costs.~~ ~~In addition to our development of XYOSTED~~^TM and our device development projects with Teva and Pfizer, we incur direct costs associated with other internal research and development projects and indirect costs that include personnel costs, administrative and other operating costs related to managing our research and development activities.

~~In February 2016, the Financial Accounting Standards Board issued Accounting Standard Update (“ASU”) No. 2016-02,~~ ~~Leases (Topic 842)~~ (“ASU 2016-02”). This new standard requires entities to recognize on its balance sheet assets and liabilities associated with the rights and obligations created by leases with terms greater than twelve months. This new standard is effective for annual reporting periods beginning after December 15, 2018, and interim periods within those annual periods and early adoption is permitted. We are in the process of evaluating the impact that the adoption of ASU 2016-02 will have on our consolidated financial statements and currently expect that most of our operating lease commitments will be subject to the new standard and recognized as operating lease liabilities and right-of-use assets upon our adoption of ASU 2016-02 effective January 1, 2019.

Our primary market risk exposure is foreign exchange rate fluctuations of the Swiss Franc to the U.S. dollar as the financial position and operating results of our subsidiaries in Switzerland are translated into U.S. dollars for consolidation. Our exposure to foreign exchange rate fluctuations also arises from transferring funds to our Swiss subsidiaries in Swiss Francs. In addition, we have exposure to exchange rate fluctuations between the Euro and the U.S. dollar. We do not currently use derivative financial instruments to hedge against exchange rate risk. The effect of foreign exchange rate fluctuations on our financial results for the period ended ~~September~~June 30, ~~2018~~2019 was not material.

We may be exposed to interest rate risk and interest rate fluctuations as a result of our long-term debt ~~financing we obtained in June 2017.~~financing. Our ~~Term Loan,~~loan, with a current outstanding principal balance of ~~$25.0~~$40.0 million accrues interest at a calculated prime-based variable rate with a maximum interest rate of 9.50%, which was the rate in effect asduring the six months ended June 30, 2019. A hypothetical increase or decrease in the interest rate of ~~September 30, 2018.~~1.0% would result in additional or lower incremental annual interest expense of $400,000.

The Company’s management, under the supervision and with the participation of the Company’s Chief Executive Officer and Chief Financial Officer, has evaluated the effectiveness of the Company’s disclosure controls and procedures (as such term is defined in Rules 13a-15(e) and 15d-15(e) under the Securities Exchange Act of 1934, as amended) as of the end of the period covered by this report. The evaluation was performed to determine whether the Company’s disclosure controls and procedures have been designed and are functioning effectively to provide reasonable assurance that the information required to be disclosed by the Company in reports filed under the Securities Exchange Act of 1934, as amended, is recorded, processed, summarized and reported within the time periods specified in the Securities and Exchange Commission’s rules and is accumulated and communicated to management, including the Company’s principal executive and principal financial officers, or persons performing similar functions, as appropriate to allow timely decisions regarding required disclosure. Based on such evaluation, the Company’s Chief Executive Officer and Chief Financial Officer have concluded that the Company’s disclosure controls and procedures as of the end of the period covered by this report were effective.

There have not been any changes in the Company’s internal control over financial reporting during the fiscal quarter to which this report relates that have materially affected, or are reasonably likely to materially affect, the Company’s internal control over financial reporting.

A control system, no matter how well conceived and operated, can provide only reasonable, not absolute, assurance that the objectives of the control system are met. Because of the inherent limitations in all control systems, no evaluation of controls can provide absolute assurance that all control issues and instances of fraud, if any, within the Company have been detected. The design of any system of controls is also based in part upon certain assumptions about the likelihood of future events, and there can be no assurance that any design will succeed in achieving its stated goals under all potential future conditions; over time, control may become inadequate because of changes in conditions, or the degree of compliance with the policies or procedures may deteriorate. Because of the inherent limitations in a cost-effective control system, misstatements due to error or fraud may occur and not be detected.

The Smith complaint contends that defendants made false and/or misleading statements and/or failed to disclose that: (i) Antares had provided insufficient data to the FDA in connection with the NDA for XYOSTED^TM®; and (ii) accordingly, Antares had overstated the approval prospects for XYOSTED^TM®. On July 27, 2018, the court entered an order appointing Serghei Lungu as lead plaintiff, Pomerantz LLP as lead counsel, and Lite DePalma Greenberg, LLC as liaison counsel for plaintiff. On August 3, 2018, the parties submitted a stipulation and proposed order, setting forth an agreed-upon schedule for responding to the complaint, which the court granted. Pursuant to that order, plaintiff filed a Consolidated Amended Class Action Complaint on October 9, 2018. On November 26, 2018, ~~and~~ defendants ~~intend to file~~filed a motion to ~~dismiss~~dismiss. Plaintiff filed an opposition to the motion on ~~or before November 26, 2018.~~January 10, 2019 and defendants filed a reply in support of their motion on February 25, 2019. On July 2, 2019, the court dismissed the complaint in its entirety without prejudice. On July 29, 2019, plaintiff filed a Consolidated Second Amended Class Action Complaint against the same parties alleging substantially similar claims. The Company believes that the claims in the Smith action lack merit and intends to defend them vigorously.

On January 12, 2018, a stockholder of our Company filed a derivative civil action, captioned Chiru Mackert, derivatively on behalf of Antares Pharma, Inc., v. Robert F. Apple, et al.(“~~Mackert~~”), in the Superior Court of New Jersey Chancery Division, Mercer County (Case No. C-000011-18). On January 17, 2018, another stockholder filed a derivative action in the same court, captioned Vikram Rao, Derivatively on Behalf of Antares Pharma, Inc. v. Robert F. Apple, et al. (“~~Rao~~”) (Case No. C-000004-18). Both complaints name Robert F. Apple, Fred M. Powell, Thomas J. Garrity, Jacques Gonella, Anton Gueth, Leonard S. Jacob, Marvin Samson and Robert P. Roche, Jr. as defendants, and the Company as nominal defendant, and they assert claims for breach of fiduciary duties, unjust enrichment, abuse of control, gross mismanagement, and waste of corporate assets arising from the same facts underlying the Smith securities class action. The plaintiffs seek damages, corporate governance and internal procedure reforms and improvements, restitution, reasonable attorneys’ fees, experts’ fees, costs, and expenses. The parties have filed a stipulation consolidating the two actions and staying the proceedings pending the court’s decision on defendants’ ~~anticipated~~ motion to dismiss the Smith action.

On January 17, 2018, a stockholder of our Company filed a derivative civil action, captioned Robert Clark, Derivatively on Behalf of Antares Pharma, Inc. v. Robert F. Apple, et al. (“Clark”) (Case No. 3:18-cv-00703-MAS-DEA), against Robert F. Apple, Thomas J. Garrity, Jacques Gonella, Leonard S. Jacob, Marvin Samson, Anton G. Gueth and Robert P. Roche, Jr. as defendants, and Company as a nominal defendant. The action was filed in the U.S. District Court for the District of New Jersey and asserts claims for breach of fiduciary duties, unjust enrichment, abuse of control, waste of corporate assets, and a violation of Section 14(a) of the Securities Exchange Act of 1934. This complaint relates to the same facts underlying the Smith securities class action and the other derivative actions. The plaintiff in Clark seeks damages, corporate governance and internal procedure reforms and improvements, reasonable attorneys’ fees, accountants’ and experts’ fees, costs, and expenses. The parties have filed a stipulation staying the action pending the court’s decision on defendants’ ~~anticipated~~ motion to dismiss the Smith action.

In addition to the information contained in this report, you should carefully consider the risk factors discussed in Part I, “Item 1A. Risk Factors” in our Annual Report on Form 10-K for the year ended December 31, ~~2017,~~2018, which could materially affect our business, financial condition or future results. ~~There have been no material changes to these risk factors other than the supplemental information and risk factors discussed below.~~ The risks described in our Annual Report on Form 10-K ~~and discussed below~~ are not the only risks we face. Additional risks and uncertainties not currently known to us or that we currently deem to be immaterial also may materially adversely affect our business, financial condition and/or operating results.

We have limited sales and marketing experience and limited experience working with payers on coverage issues, and we can provide no assurance on the successful launch and commercialization of our products.

We have limited sales and marketing experience, and limited experience working with payers on coverage issues. The launch and successful commercialization of a new product requires substantial dedication of financial and other resources and include steps related to manufacturing, logistics, sales and marketing, and establishing insurance coverage and reimbursement. We launched OTREXUP^® in February 2014, and are in the process of launching XYOSTED™. Although we have hired and expect to continue to hire highly qualified personnel with specialized expertise, as a company, we have limited experience commercializing pharmaceutical products on our own. In order to commercialize our products, we have built and expect to continue to build our sales, marketing, distribution, managerial and other non-technical capabilities and have made and expect to continue to make arrangements with third parties to perform these services when needed. In January 2015, we hired sales representatives and district managers to fill our sales territories for OTREXUP^®. In connection with the launch of XYOSTED™, we will begin the process of onboarding approximately 60 sales representatives and are working on our pricing, reimbursement, marketing and distribution strategies.

If we are unable to successfully implement our sales and marketing plans and drive adoption by patients and physicians of our products through our sales, marketing and commercialization efforts, then we may not be able to generate sustainable revenues growth from product sales which will have a material adverse effect on our business and future product opportunities.

Similarly, we may not be successful in maintaining the necessary commercial infrastructure, including sales representatives, managed care, medical affairs and pharmacovigilance teams. The development of commercialization capabilities to market of our products has been and will continue to be expensive and time-consuming. As we continue to develop, maintain and grow these capabilities, we will have to compete with other pharmaceutical companies to recruit, hire, train and retain sales and marketing personnel. If we have underestimated the necessary sales and marketing capabilities or have not established the necessary infrastructure to support successful commercialization, or if our efforts to do so take more time and expense than anticipated, our ability to market and sell any drug products may be adversely affected.

There is no guarantee that patients and healthcare providers will adopt our or our partners’ products, and that we and our partners will be able to receive adequate payer coverage and reimbursement. New information concerning our or our partners’ products learned through required post-approval studies and product use may also result in changes to our or our partners’ products. Should any of these events occur, they could have a material and adverse effect on our operations and business.

There is no guarantee that patients and healthcare providers will adopt any newly approved products, or that insurers will provide adequate coverage and reimbursement. Any labeled limitations on the use of a product or warnings could discourage adoption of the product by patients, healthcare providers, and insurers. By example, the XYOSTED™ label includes a boxed warning concerning blood pressure increases that can increase the risk for major adverse cardiovascular events. Teva’s epinephrine auto injector drug-device combination product is also subject to certain labeled warnings. These could ultimately discourage patients from using and healthcare providers from prescribing our and our partners’ products.

Moreover, we and our partners may experience a delay in receiving coverage and reimbursement for any new products or may not receive adequate levels of coverage or reimbursement at all. Product labeling restrictions and warnings may also discourage payers from providing adequate levels of coverage and reimbursement. We and our partners, accordingly, may need to take steps to assist patients to afford our products, such as offering bridge programs, free-trial, discounts, rebates and co-pay coupon programs. These programs, however, may not ultimately be successful.

If patients and healthcare providers do not adopt any new product, or if insurers restrict patient access or disadvantage our or our partners’ products in their formularies or otherwise do not provide adequate coverage and reimbursement, we and our partners may not be able to generate sustainable revenues growth from product sales and royalties which will have a material adverse effect on our business and future product opportunities.

Any post-approval requirements, including phase IV studies and Risk Evaluation and Mitigation Strategies, or REMS, may also require the dedication of substantial time and resources. By example, as a post-marketing requirement for XYOSTED™, the FDA has asked us to conduct a label comprehension study that assesses patients’ understanding of key risk messages in the Medication Guide for XYOSTED™ and a study of testosterone replacement therapy in pediatric males ages 14 years and older for conditions associated with a deficiency or absence of endogenous testosterone. The label comprehension study findings may result in revisions to the Medication Guide to optimize patients’ understanding of important risks of XYOSTED™ and potentially other label restrictions. Additionally, the outcome of any post-approval studies, including the pediatric study, is uncertain and may not result in

an expanded label indication or could result in additional labeling requirements or other post-approval restrictions or regulatory actions. The label comprehension study must be completed by 2020 and the pediatric study by the end of 2026. The conduct of these studies will require dedication of funds and resources.

Additionally, use of our or our partners’ products by patients and in phase IV and post-marketing studies may result in the discovery of new information concerning the products. By example, the products may be found to be less effective than initially demonstrated, or new, more severe, or more frequent adverse events or side effects may be reported. This may result in regulatory or other actions, including, product liability actions, enforcement actions, distribution and manufacturing restrictions, changes to product labeling and promotional materials, the imposition of post-market requirements, such as REMS or additional phase IV studies, withdrawal of marketing application approvals, withdrawal of the product from the market, refusal to approve new marketing applications or supplements, product recalls, clinical holds and suspension of clinical studies, safety alerts, dear healthcare provider letters, adverse publicity, and reimbursement and insurance coverage consequences, among others. Should any of these events occur, they could have a material and adverse effect on our operations and business.

If we or our partners are unable to achieve and maintain adequate levels of coverage and reimbursement for our or our partners’ products or any of our or our partners’ future products for which we or our partners receive regulatory approval, their commercial success may be severely hindered.

Successful sales of our products depend on the availability of adequate coverage and reimbursement from third-party payers. Patients who are prescribed medicine for the treatment of their conditions generally rely on third-party payers to reimburse all or part of the costs associated with their prescription drugs. Adequate coverage and reimbursement from governmental healthcare programs, such as Medicare and Medicaid, and commercial payers is critical to new product acceptance. Coverage decisions may depend upon clinical and economic standards that disfavor new drug products when more established or lower cost therapeutic alternatives are already available or subsequently become available. Assuming coverage is approved, the resulting reimbursement payment rates might not be adequate or may require co-payments that patients find unacceptably high. Patients are unlikely to use our products unless coverage is provided and reimbursement is adequate to cover a significant portion of the cost of our products.

In addition, the market for our products will depend significantly on access to third-party payers' drug formularies, or lists of medications for which third-party payers provide coverage and reimbursement. Health plans often used tiered formularies that prefer one branded product in a therapeutic class over another through different patient co-payment amounts, and disadvantaging some products through techniques such as step therapy and prior authorization. Many states use formularies and preferred drug lists to obtain supplemental Medicaid rebates in excess of those required for Medicaid coverage. The industry competition to be included in such formularies and not disadvantaged often leads to downward pricing pressures on pharmaceutical companies. Also, third-party payers may refuse to include a particular branded drug in their formularies or otherwise restrict patient access to a branded drug when a less costly generic equivalent or other alternative is available. Additionally, certain third-party payers restrict or block access to patients for new products until a clinical review has occurred or clinical evidence is provided to support the benefits for covered patients. These restrictions may be imposed for months or longer and some third-party payers may refuse to add new products to their formularies or otherwise restrict patient access. To ensure sales, manufacturers often must provide multiple discounts on the same drug in the chain of distribution to the health care provider and the payer. Further, manufacturers are required to assume responsibility for Medicare Part D prescription costs for innovator drugs and biologics and authorized generics while the beneficiary is in the coverage gap. Increasingly, payers are looking for metrics and performance-based pricing to justify increased cost of therapeutic advancements. Even if coverage is obtained, the net realization from price concessions may negatively impact our profitability. Government health programs also impose inflation penalties which may have adverse consequences if we increase prices in the future.

Our partnered products encounter similar issues in obtaining reimbursement from third-party payers. While we are unable to control the reimbursement rate or discounts contracted with third-party payers by our partners, these rates ultimately affect our profit sharing on Sumatriptan Injection USP and royalties on products such as the Makena^® ~~Subcutaneous Auto-Injector, the Teva epinephrine auto injector drug-device combination product, Elestrin~~^® ~~and Gelnique~~^®.

Third-party payers, whether foreign or domestic, or governmental or commercial, are developing increasingly sophisticated methods of controlling healthcare costs. In addition, in the U.S., no uniform policy of coverage and reimbursement for drug products exists among third-party payers. Therefore, coverage and reimbursement for drug products can differ significantly from payer to payer.

Further, we believe that future coverage and reimbursement will likely be subject to increased restrictions both in the U.S. and in international markets. Third-party coverage and reimbursement for OTREXUP^®, XYOSTED™ or any of our other products and product candidates for which we may receive regulatory approval may not be available or adequate in either the U.S. or international markets, which could have a material adverse effect on our business, results of operations, financial condition and prospects.

~~We depend on Teva to manufacture the drug and finished packaged product and to distribute and commercialize the epinephrine auto-injector in the U.S.~~

We have entered into a license, development and supply agreement with Teva, pursuant to which Antares developed and is the exclusive supplier of the device for an epinephrine auto injector product to be marketed by Teva in the U.S. Teva’s ANDA for a generic epinephrine auto injector drug-device combination product was approved by the FDA in August 2018 and Teva is preparing for a launch of the product.

There is no guarantee that our partnership with Teva will be successful. Teva controls the manufacture and supply of the drug, epinephrine, and the final assembly of the devices and packaging of the finished product, and has complete control over the launch and continuous commercialization and sale of the epinephrine auto injector product. If, at any time, Teva ceases to manufacture and supply the epinephrine drug or fails to produce sufficient supplies of the drug, Teva will be unable to produce a finished product and we may be unable to sell our auto injectors for this product to Teva resulting in less revenue for us.

In addition, if Teva is unable to complete the final assembly and packaging of the finished epinephrine auto injector product, we may receive less revenue than desired or expected. If Teva is unable to produce sufficient supplies of the drug or finished epinephrine auto injector product in accordance with cGMPs, Teva may be subject to regulatory enforcement action. We will also rely on Teva to commercialize and distribute the product, including determining the price and payer coverage. If Teva is unsuccessful in commercializing the product, the resulting revenue may be lower than expected. Additionally, Teva controls the business strategy, manufacturing and distribution decisions concerning the epinephrine auto injector product. Such decisions by Teva may be beyond our control and may impact the success of the epinephrine auto injector product. As a result, we may receive less revenue than desired or expected.

Further, Teva is subject to potential competition regarding another generic version of the epinephrine auto injector product, such additional competition could result in receiving less revenue than expected.

We rely on third parties to manufacture our and our partners’ products. If we do not develop and maintain relationships with manufacturers and/or assemblers of our and our partners’ drug/device products or product candidates, or if such third parties are unable to manufacture or supply product, or assemble and package the final products, we may be unable to successfully manufacture, assembly, package and sell our and our partners’ products, which could have a material adverse effect on our business.

~~We do not possess the facilities to manufacture commercial quantities of our or our partners’ drug/device combination products or components, including OTREXUP~~^®~~, XYOSTED~~^TM~~, VIBEX~~^® ~~Sumatriptan Injection USP, epinephrine auto-injector devices, Makena~~^® auto injectors or any other of our or our partners’ products or product candidates. We also do not possess the facilities to manufacture clinical supplies of any product candidates or components. We must contract with third parties to produce products, components, and product candidates and to assemble and package products and components according to specifications and government regulations. The future development and delivery of our and our partners’ products and product candidates depends on the capability, timely, profitable and competitive performance of these third parties. There is also no assurance that such third parties will be willing to manufacture, assemble or sell the drug/device products or components. A limited number of manufacturers exist that are capable of manufacturing our and our partners’ products, components, and product candidates. We and our partners may fail to contract with the necessary third parties or we and our partners may contract with third parties on terms that may not be favorable to us.

Our and our partners’ contract manufacturers must comply with all applicable manufacturing requirements, including cGMPs for drug products and QSRs for medical devices. Before approving any marketing application, FDA will inspect the product manufacturing facilities. We and/or our partners must obtain FDA approval for a product’s or product candidate’s manufacturing process and facilities to receive product marketing approval, which we and/or our partners may never obtain or may not be able to maintain. Moreover, following product approval, FDA regularly also inspects drug and device manufacturers to ensure continued compliance with FDA’s requirements. If we or our partners are not able to obtain or maintain this approval and regulatory compliance, we and/or they would not be able to receive product approval, and commercialize and/or sell the applicable products. Moreover, should any manufacturer fail to comply with the applicable regulatory requirements, we, our partners, and/or the manufacturer may face regulatory consequences, including enforcement actions and/or product recalls. Additionally, use of contract manufacturers exposes us to risks in the manufacturer's business such as their potential inability to perform from a technical, operational or financial standpoint. Failure by a contract manufacturer to supply product, could have a material adverse effect on our ability to generate revenue and profit.

In addition, contract manufacturers may utilize their own technology, technology developed by us, technology developed by our partners, or technology acquired or licensed from third parties. When contract manufacturers develop proprietary process technology, our reliance on such contract manufacturers is increased. Technology transfer from the original contract manufacturer may be required. Any such technology transfer may also require transfer of requisite data for regulatory purposes, including information contained in a proprietary drug or device master file held by a contract manufacturer. We and/or our partners would be dependent on

the contract manufacturer for the maintenance and right of reference to the drug or device master file. If the contract manufacturer fails to maintain a drug or device master file or withdraws our or our partners’ right of reference, we and/or our partners may no longer be able to manufacture, develop, market, and sell our or our partners’ products or product candidates. FDA approval of the new manufacturer and manufacturing site, as well as certain changes to the manufacturing process, would also be required.

~~We rely on multiple commercial supply arrangements with third-party manufacturers for, including, without limitation:~~

~~Reliance on third-party manufacturers entails risks to which we would not be subject if we manufactured products ourselves, including:~~

We and our partners depend on these third-party manufacturers to comply with cGMPs/QSRs enforced by the FDA and other regulatory requirements and to deliver materials on a timely basis. To the extent that a contract manufacturer cannot deliver adequate quantities of clinical supplies, our or our partners’ product development efforts may be delayed. To the extent that a contract manufacturer cannot deliver adequate quantities of commercial products, our commercialization efforts would be inhibited and as a result our revenue and profit may be adversely impacted. In addition, because regulatory approval to manufacture a drug is site-specific, the FDA and other regulatory authorities will repeatedly inspect our and our partners’ current and future third-party manufacturers’ facilities for compliance with cGMPs/QSRs. If we, our partners, or third-party manufacturers fail to comply with applicable regulatory requirements, a regulatory agency may issue warning letters or suspend or withdraw our regulatory approval for approved or in-market products, refuse to approve any marketing applications, or refuse to allow future or current development of product candidates, among other things. Our third-party manufacturers may also fail to pass the audits by our or our partners’ internal quality and regulatory group. Any of these actions could delay or prevent our development of products, delay or prevent the submission of these products for regulatory approval, delay or prevent marketing approval, or result in insufficient product or product candidate quantity to support commercial demand or development. We may also be required to replace manufacturers, which would be time consuming and expensive, and we may not be able to reach favorable agreements with or FDA approval for alternative manufacturers. As a result, our business, financial condition and results of operations could be seriously harmed. See additional risk factors associated with manufacturing in the section “Risks Related to Regulatory Matters.”

In addition, we may consider entering into additional manufacturing arrangements with third party manufacturers. In each case, we will incur significant costs in obtaining the regulatory approvals and taking the other steps necessary to begin commercial production by these manufacturers.

Pursuant to the requirements of the Securities Exchange Act of 1934, the registrant has duly caused this report to be signed on its behalf by the undersigned thereunto duly authorized.
