You should read the following discussion and analysis of our financial condition and results of operations together with our consolidated financial statements and the related notes appearing elsewhere in this Quarterly Report on Form 10-Q and our historical consolidated financial statements and the related notes thereto appearing in our Annual Report on Form 10-K for the year ended December 31, 2021, filed with the Securities and Exchange Commission on March 29, 2022. Some of the information contained in this discussion and analysis or set forth elsewhere in this Quarterly Report, including information with respect to our plans and strategy for our business, includes forward-looking statements that involve risks and uncertainties. As a result of many factors, including those factors set forth in the "Risk Factor Summary" and "Risk Factors" sections of this Quarterly Report, our actual results could differ materially from the results described in or implied by the forward-looking statements contained in the following discussion and analysis.

On September 16, 2022, our board of directors effected a one-for-twenty five reverse stock split of our ordinary shares, or the Reverse Stock Split. As a result of the Reverse Stock Split, every twenty five ordinary shares of $0.01 each (nominal value) in the authorized and unissued and authorized and issued share capital of the company were consolidated into one ordinary share of $0.25 each (nominal value), and the nominal value of each ordinary share was subsequently immediately reduced from $0.25 to $0.01 nominal value per share. All outstanding stock options, restricted stock units and warrants entitling their holders to purchase or acquire ordinary shares were adjusted as a result of the Reverse Stock Split. Accordingly, all ordinary share, common share, equity award, warrant and per share amounts have been adjusted to reflect the Reverse Stock Split for all prior periods presented.

Overview

We are a biopharmaceutical company engaged in the commercialization and research and development of novel anti-infective agents to treat serious infections. We have the commercial rights to two approved products, SIVEXTRO, for acute bacterial skin and skin structure infections, or ABSSSI, and XENLETA, for community-acquired bacterial pneumonia, or CABP, as well as one development product candidate, CONTEPO for complicated urinary tract infections, or cUTIs. In August 2019, our first product was approved by the U.S. Food and Drug Administration, or FDA, and we made it available in the United States in September 2019 under the brand name XENLETA. XENLETA (lefamulin) is a first-in-class semi-synthetic pleuromutilin antibiotic for systematic administration in humans discovered and developed by our team. XENLETA is designed to inhibit the synthesis of bacterial protein, that is required for bacteria to grow, by binding with high affinity, high specificity and at molecular targets that are different than other antibiotic classes. Based on results from two global, Phase 3 clinical trials, we believe that XENLETA is well-positioned for use as a first-line monotherapy for the treatment of CABP, due to its novel mechanism of action, targeted spectrum of activity, resistance profile, achievement of substantial drug concentration in lung tissue and fluid, availability of oral and intravenous, or IV, formulations and a generally well-tolerated safety profile. We believe XENLETA represents a potentially important treatment option for the five million adults in the United States diagnosed with CABP each year.

SIVEXTRO is approved for the treatment of ABSSSIs caused by certain susceptible Gram-positive microorganisms. Before we were permitted to sell SIVEXTRO under the Distribution Agreement, we were required to secure a sales force of a certain size and the restrictions related to COVID-19 needed to be eased in a sufficient manner to permit us to promote and distribute SIVEXTRO. Re-securing a sales force of a certain size for the promotion and distribution of SIVEXTRO resulted in significant additional expense and our efforts to maintain a sales force may not be successful. We continue to operate a virtual and in-person sales effort with community-based expertise with Amplity Health, which is a contract sales organization, with a sales effort for SIVEXTRO and XENLETA. We expanded this effort to 60 sales representatives and may expand it further. We have maintained a virtual promotion effort piloted with sales representatives since the third quarter of 2021 and engaged in-house district managers in April 2022.

XENLETA is approved for the treatment of CABP in adults in the United States. The National Institute for Allergy and Infectious Diseases, or NIAID, has identified that secondary bacterial pneumonia caused by common upper respiratory tract bacteria plays a predominant role in the cause of death in pandemic influenza. NIAID recommends that

the prevention, diagnosis, prophylaxis, and treatment of secondary bacterial pneumonia, as well as the stockpiling of antibiotics and bacterial vaccines, be high priorities for pandemic planning.

Since inception, we have incurred significant operating losses. As of September 30, 2022 we had an accumulated deficit of $630.1 million. To date, we have financed our operations primarily through equity offerings, convertible and term debt financings and research and development support from governmental grants and proceeds from our licensing agreements and SIVEXTRO and XENLETA product sales. We have devoted substantially all of our efforts to research and development, including clinical trials, as well as commercializing SIVEXTRO and XENLETA. Our ability to generate profits from operations and become and remain profitable depends on our ability to successfully develop and commercialize drugs that generate significant revenue.

Recent Developments

In October 2022, we determined to pivot our strategy to focus our commercialization efforts primarily on SIVEXTRO, suspend our early-stage research and development activities and streamline our operations to focus on maximizing our cash position to preserve optionality as we explore strategic options. Based on the determination to pivot our strategy, we implemented a reduction-in-force, including implementing a hiring freeze, relating to our research and development organization and additional areas of our business. As part of the reduction-in-force, we suspended all of our early-stage research and development activities and reduced global headcount by approximately 40% impacting nearly all functional areas within our organization. We estimate that we will incur approximately $0.3 million of charges during the fourth quarter of 2022 related to expected severance, benefits and related costs, which amounts may be greater than currently expected. We expect to realize estimated cost savings of approximately $10.0 million in 2023 as compared to 2022.

As part of our efforts to extend our cash runway and maximize the value of our assets, in addition to our ongoing commercialization activities, we may also consider potential strategic transactions, including the sale, license or other disposition of one or more of our assets, technologies or products, including XENLETA and CONTEPO. We have retained Torreya Capital to advise on our expoloration of the strategic options available to us. Our board of directors has not determined to proceed with any particular strategic transaction and there can be no assurance that any such strategic transaction will be completed on favorable terms or at all.We expect to continue to incur significant expenses and have negative cash flows for at least the next several years. Our expenses will increase if we suffer any regulatory delays or are required to conduct additional clinical trials to satisfy regulatory requirements. If we obtain marketing approval for CONTEPO or any other product candidate that we develop, in-license or acquire, we expect to incur significant commercialization expenses related to product sales, marketing, distribution and manufacturing. Based on our current forecasts and plans, we will need to obtain substantial additional capital in connection with our continuing operations. Adequate additional capital may not be available to us on acceptable terms, or at all, and we may not be able to consummate a strategic sale, license or other disposition of one or more of our assets on acceptable terms, or at all. If we are unable to raise capital or to monetize one or more of our assets, we could be forced to delay, reduce or eliminate our commercialization efforts, conduct additional reductions-in-force or cease our operations, which could cause our shareholders to lose all or part of their investment.

Business Update Regarding COVID-19

On March 11, 2020, the World Health Organization declared the outbreak of COVID-19 as a pandemic. The outbreak had an impact on the global economy, resulting in rapidly changing market and economic conditions. National and local governments around the world instituted certain measures, including travel bans, prohibitions on group events and gatherings, shutdowns of certain non-essential businesses, curfews, shelter-in-place orders and recommendations to practice social distancing. The COVID-19 pandemic has presented a substantial public health and economic challenge around the world and is affecting our employees, communities and business operations, as well as the U.S. economy and financial markets.

The extent of the impact of COVID-19 on our business will depend on the length and severity of the pandemic, including the extent there is any resurgence of the COVID-19 virus or any variant strains of the virus, the availability and effectiveness of vaccines and the impact of the foregoing on our business. The full extent to which the COVID-19

Table of Contents

pandemic will continue to directly or indirectly impact our business, results of operations and financial condition will depend on future developments that are highly uncertain and cannot be accurately predicted. The full impact of COVID-19 is unknown. Federal, state and local governmental policies and initiatives designed to reduce the transmission of COVID-19 have resulted in, among other things, a significant reduction in physician office visits, the cancellation of elective medical procedures, and the adoption of hybrid-remote-working policies, all of which have had, and we believe will continue to have, an impact on our consolidated results of operations, financial position and cash flows.

Financial Operations Overview

Revenue

In September 2019, we had our commercial launch of XENLETA and, in April 2021 we began exclusive distribution of SIVEXTRO in the United States and certain of its territories. For the nine months ended September 30, 2022, we recorded $24.2 million of SIVEXTRO product revenue, net of gross-to-net accruals and adjustments for returns, and $0.1 million of XENLETA product revenue, net of gross-to-net accruals and adjustments for returns. With a near term shelf life expiration, we recorded a $0.3 million returns reserve adjustment in the first three quarters of 2022. We launched a new 10-count blister pack of XENLETA in the fourth quarter of 2021, which has a four year shelf life. Future product revenues will be generated by the amount and frequency of reorders from our wholesale customers based on the ultimate consumption patterns from the end users of SIVEXTRO and XENLETA.

Collaboration revenues for the nine months ended September 30, 2022 were $0.9 million which includes collaboration revenues related to the restructured China Region License Agreement, a portion of which was recognized over the estimated period of the manufacturing collaboration and regulatory support that has been provided to Sumitomo Pharmaceuticals (Suzhou).

Our revenues for the nine months ended September 30, 2022 included governmental research premiums and the benefit of government loans at below-market interest rates.

Cost of Revenues

Cost of revenues represented 20.5% and 14.3% of our total operating expenses for the nine months ended September 30, 2022 and 2021, respectively. Cost of revenues primarily represent the cost of the product itself, labor and overhead, and any reserve for excess or obsolete inventory. Other cost of revenues include costs associated with the manufacturing collaboration and regulatory support under our licensing agreements. The increase in cost of revenue for the nine months ended September 30, 2022 was primarily due to the launch of SIVEXTRO under our own National Drug Code, or NDC, on April 12, 2021.

Research and Development Expenses

Research and development expenses represented 19.6% and 18.5% of our total operating expenses for the nine months ended September 30, 2022 and 2021, respectively.

For each of our research and development programs, we incur both direct and indirect expenses. Direct expenses include third-party expenses related to these programs such as expenses for manufacturing services (prior to our products receiving FDA approval, after which time these costs are capitalized in inventory until product is sold), non-clinical and clinical studies and other third party development services. Indirect expenses include salaries and related costs, including stock-based compensation, for personnel in research and development functions, infrastructure costs allocated to research and development operations, costs associated with obtaining and maintaining intellectual property associated with our research and development operations, laboratory consumables, consulting fees related to research and development activities and other overhead costs. We utilize our research and development staff and infrastructure resources across multiple programs, and many of our indirect costs historically have not been specifically attributable to a single program. Accordingly, we cannot state precisely our total indirect costs incurred on a program-by-program basis.

Total research and development expenses $ 11,637 $ 10,239

We expect to continue to incur research and development expenses in connection with required regulatory activities, our activities related to our ongoing pediatric studies of lefamulin for the treatment of CABP and of CONTEPO for the treatment of cUTI. It is difficult to estimate the duration and completion costs of our research and development programs.

We initiated screening of our Phase 1 clinical trial to assess the safety and pharmacokinetics of oral and intravenous XENLETA for the treatment of resistant bacterial infections in adult patients with CF in March 2022, and have completed enrollment. We expect to report topline results from the trial in the fourth quarter of 2022.

The successful development and commercialization of our product candidates is highly uncertain. This is due to the numerous risks and uncertainties associated with product development and commercialization, including the uncertainty of:

the efficacy and potential advantages of our product candidates compared to

? alternative treatments, including any standard of care, and our ability to

achieve market acceptance for any of our product candidates that receive

marketing approval;

the costs and timing of commercialization activities, including product sales,

? marketing, distribution and manufacturing, for any of our product candidates

that receive marketing approval;

? the costs, timing and outcome of regulatory review of our product candidates;

? the scope, progress, costs and results of clinical trials and other research

and development activities; and

the costs and timing of preparing, filing and prosecuting patent applications,

? maintaining, enforcing and protecting our intellectual property rights and

defending against any intellectual property-related claims.

A change in the outcome of any of these variables with respect to the development of our product candidates could result in a significant change in the costs and timing associated with the development of that product candidate. For example, if the FDA or another regulatory authority were to require us to conduct clinical trials or other testing beyond those that we have completed or currently contemplate will be required for the completion of clinical development of any product candidate, we could be required to expend significant additional resources and time on the completion of clinical development of that product candidate.

Selling, General and Administrative Expenses

Selling, general and administrative expenses represented 59.9% and 67.2% of our total operating expenses for the nine months ended September 30, 2022 and 2021, respectively.

Selling, general and administrative expenses consist primarily of salaries and related costs, including stock-based compensation not related to research and development activities for personnel in our finance, information technology, commercial, medical affairs and administrative functions, as well as costs related to our contract commercial



                                       30

organization, to provide community-based commercial and sales services. Selling, general and administrative expenses also include costs related to professional fees for auditors, lawyers and tax advisors and consulting fees not related to research and development operations, as well as functions that are partly or fully outsourced by us, such as accounting, payroll processing and information technology.

We expect selling, general and administrative expenses for the fiscal year ending December 31, 2022 to be lower than what was reported for the fiscal year ended December 31, 2021.

Critical Accounting Estimates

Our management's discussion and analysis of our financial condition and results of operations is based on our consolidated financial statements, which we have prepared in accordance with generally accepted accounting principles in the United States, or U.S. GAAP. The preparation of our consolidated financial statements requires us to make estimates and assumptions that affect the reported amounts of assets and liabilities and the disclosure of contingent assets and liabilities at the end of the reporting period, as well as the reported revenues and expenses during the reporting periods and how our estimates and assumptions have changed over each relevant reporting period. However, these estimates and assumptions are subject to uncertainty, due to unknown trends and events and various other factors that we believe to be reasonably likely under the circumstances, the results of which form the basis for making judgments about the carrying values of assets and liabilities that are not readily apparent from other sources. Actual results may differ from these estimates under different assumptions or conditions.

Our significant accounting policies and estimates are described in more detail in the notes to our consolidated financial statements appearing elsewhere in this filing. However, we believe that the following accounting policies and estimates are the most critical to aid you in fully understanding and evaluating our financial condition and results of operations.

Revenue Recognition

Under Accounting Standards Codification, or ASC, 606, an entity recognizes revenue when its customer obtains control of promised goods or services, in an amount that reflects the consideration that the entity expects to receive in exchange for those goods or services. We then recognize as revenue the amount of the transaction price that is allocated to the respective performance obligation when (or as) the performance obligation is satisfied as services are rendered.

The transaction price that we recognize as revenue reflects the amount we expect with the sale and transfer of control of the product to our customers. Once the customer takes control of the product, our performance obligation under the sale contract is complete and revenue is recorded net of applicable reserves for various types of variable consideration. The types of variable consideration are as follows:



 ? Fees-for-service;


 ? Product returns;


 ? Chargebacks and rebates;


 ? Government rebates;


? Commercial payer and other rebates;

? Group Purchasing Organizations, or GPO, administration fees; and

? Voluntary patient assistance programs




                                       31

  Table of Contents

In determining the amounts of variable consideration, we must make significant judgments and estimates. In assessing the amount of net revenue to record, we consider both the likelihood and the magnitude of the revenue reversal. Actual amounts of consideration ultimately received may differ significantly from our estimates. Factors that can impact these estimates include business related dynamics such as; the growth of the markets, and uptake of product acceptance within these markets. If actual results in the future vary from our estimates, we adjust our estimates which would affect net product revenue in the period such variances become known.

XENLETA Inventory and Purchase Commitments

Our XENLETA inventory is stated at the lower of cost or net realizable value, with cost determined on a first-in, first-out basis, and consists primarily of material costs, third-party manufacturing costs and related transportation costs in our supply chain. Our inventory is subject to expiration dating, which can be extended in certain circumstances. We also have non-cancellable purchase commitments for XENLETA active pharmaceutical ingredient, or API. We continually evaluate forecasted product sales for XENLETA which is used in estimating the need to reserve for estimated excess, slow-moving and obsolete inventory on hand and potential accrued losses on firm purchase commitments. For both the nine months ended September 30, 2022 and 2021, we recorded $0.9 million of charges to our non-cash reserve for excess and obsolete inventory due to timing of expiry dating of expiring inventory. To the extent forecasted sales for XENLETA fluctuate based on the evolution of patient demand, there could be additional adjustments to reserves for inventory on hand or adjustments to purchase commitments.

Revenues

Revenues for the three months ended September 30, 2022 were $9.2 million compared to $8.9 million for the three months ended September 30, 2021. The $0.3 million increase was driven by an increase in product revenue, net, offset by a decrease in collaboration revenues.

  Table of Contents

Cost of Revenues

Cost of revenues for the three months ended September 30, 2022 was $4.4 million compared to $4.2 million for the three months ended September 30, 2021. The $0.2 million increase was primarily due to SIVEXTRO costs, which were not incurred prior to the launch of our own SIVEXTRO NDC on April 12, 2021. Cost of revenues for XENLETA primarily represents direct and indirect manufacturing costs, while cost of revenues for SIVEXTRO represent the actual purchase cost for the finished product from Merck. For the three months ended September 30, 2022 and 2021, cost of revenues include $106,000 and $3,000, respectively, of inventory write-off and a non-cash reserve adjustment for excess and obsolete XENLETA inventory due to timing of expiring inventory.

Research and Development Expenses

Research and development expenses for the three months ended September 30, 2022 were $4.0 million compared to $3.2 million for the three months ended September 30, 2021. The $0.8 million increase was primarily due to a $0.5 million increase in consulting fees and a $0.4 million increase in research materials and purchased services driven by our Phase 1 trial to assess the safety and pharmacokinetics of oral and intravenous XENLETA for the treatment of resistant bacterial infections in adult patients with cystic fibrosis.

Selling, General and Administrative Expenses

Selling, general and administrative expenses for the three months ended September 30, 2022 were $11.9 million compared to $12.3 million for the three months ended September 30, 2021. The $0.3 million decrease was driven by a decrease in personnel costs and a decrease in stock-based compensation expenses.

Other Income, Net

Other income, net, increased by $0.2 million for the three months ended September 30, 2022 primarily due to remeasurements of our foreign currency account balances.

Interest Expense, Net

Interest expense, net was $0.1 million for the three months ended September 30, 2022 compared to $0.2 million for the three months ended September 30, 2021.

Income Tax Benefit (Expense)

Our income tax expense for the three months ended September 30, 2022 was $0.5 million compared to $0.3 million of income tax benefit for the three months ended September 30, 2021.

Revenues

Revenues for the nine months ended September 30, 2022 were $26.4 million compared to $19.6 million for the nine months ended September 30, 2021. The $6.7 million increase was primarily due to an $8.6 million increase in SIVEXTRO product revenue, net, partly offset by a $2.5 million decrease in collaboration revenues.

Cost of Revenues

Cost of revenues for the nine months ended September 30, 2022 was $12.2 million compared to $7.9 million for the nine months ended September 30, 2021. The $4.3 million increase was primarily due to SIVEXTRO costs, which were not incurred prior to the launch of our own SIVEXTRO NDC on April 12, 2021. Cost of revenues for XENLETA primarily represents direct and indirect manufacturing costs, while cost of revenues for SIVEXTRO represent the actual purchase cost for the finished product from Merck. For the nine months ended September 30, 2022 and 2021, cost of revenues include $0.4 million and $0.3 million, respectively, of inventory write-off and a non-cash reserve adjustment for excess and obsolete XENLETA inventory due to timing of expiring inventory.

Research and Development Expenses

Research and development expenses for the nine months ended September 30, 2022 were $11.6 million compared to $10.2 million for the nine months ended September 30, 2021. The $1.4 million increase was primarily due to a $0.9 million increase in research materials and purchased services driven by our Phase 1 trial to assess the safety and pharmacokinetics of oral and intravenous XENLETA for the treatment of resistant bacterial infections in adult patients with cystic fibrosis, and a $0.4 million increase in advisory and external consultancy expenses.

Selling, General and Administrative Expenses

Selling, general and administrative expenses for the nine months ended September 30, 2022 were $35.7 million compared to $37.2 million for the nine months ended September 30, 2021. The $1.5 million decrease was primarily due to a decrease in advisory and external consultancy expenses.

Other Income, Net

Other income, net was $0.6 million for the nine months ended September 30, 2022 compared to $0.5 million for the nine months ended September 30, 2021, primarily due to remeasurements of our foreign currency account balances.

Interest Expense, Net

Interest expense, net decreased by $0.1 million for the nine months ended September 30, 2022 as compared to the nine months ended September 30, 2021.

Income Tax Expense

Our income tax expense for the nine months ended September 30, 2022 was $1.3 million compared to $0.5 million for the nine months ended September 30, 2021.

Liquidity and Capital Resources

Since our inception, we have incurred net losses and generated negative cash flows from our operations. To date, we have financed our operations through the sale of equity securities, convertible and term debt financings, research and development support from governmental grants and loans and proceeds from licensing agreements and XENLETA and SIVEXTRO product sales. As of September 30, 2022, we had cash, cash equivalents and restricted cash of $14.8 million. We will need to obtain substantial additional funding to achieve our business objectives during the next 12 months and beyond. If we are unable to raise additional funds when needed, including through the sale of our ordinary shares for cash, we may be unable to pursue our business plans and strategy, and we may be required to delay, limit, reduce or terminate our product development or commercialization efforts or grant rights to develop and market product candidates that we would otherwise prefer to develop and market ourselves. We may also consider potential strategic transactions, including the potential sale, license or other disposition of one or more of our assets, technologies or products including XENLETA and CONTEPO and have retained Torreya Capital to advise on our expoloration of the strategic options available to us. Additionally, our inability to raise funds when needed may cause investors to lose confidence in us and raise substantial doubt about our ability to continue as a going concern, which may cause our ordinary share price to decline and our shareholders to lose all or part of their investment.

In September 2021, we entered into a purchase agreement, or Purchase Agreement, with Lincoln Park Capital Fund, LLC, or Lincoln Park, which, subject to the terms and conditions, provides that we have the right to sell to Lincoln Park and Lincoln Park is obligated to purchase up to $23.0 million of our ordinary shares. In addition, under the Purchase Agreement, we agreed to issue a commitment fee of 25,298 ordinary shares, or the Commitment Shares, as consideration for Lincoln Park entering into the Purchase Agreement and for the payment of $0.01 per Commitment Share. Under the Purchase Agreement, we may from time to time, at our discretion, direct Lincoln Park to purchase on any single business day, or a Regular Purchase, up to (i) 16,000 ordinary shares if the closing sale price of our ordinary shares is not below $0.25 per share on Nasdaq, (ii) 24,000 ordinary shares if the closing sale price of our ordinary shares is not below $50.00 per share on Nasdaq or (iii) 32,000 ordinary shares if the closing sale price of our ordinary shares is not below $75.00 per share on Nasdaq. In addition to Regular Purchases, we may also direct Lincoln Park to purchase other amounts as accelerated purchases or as additional accelerated purchases on the terms and subject to the conditions set forth in the Purchase Agreement. Notwithstanding the foregoing, we may direct Lincoln Park to purchase on any single business day ordinary shares with a purchase price equal to or greater than $200,000 irrespective of the number of ordinary shares required to approximate that amount. In any case, Lincoln Park's commitment in any single Regular Purchase may not exceed $2.5 million absent a mutual agreement to increase such amount. As of September 30, 2022, we have issued and sold an aggregate of 320,000 ordinary shares pursuant to the Purchase Agreement and received net proceeds of $4.6 million. From October 1, 2022 and through the date of this filing, we did not sell any shares under the Purchase Agreement. As of the date of this filing, we may issue and sell ordinary shares for gross proceeds of up to $18.5 million under the Purchase Agreement, subject to the Nasdaq rules which may limit our ability to make sales of our ordinary shares to Lincoln Park in excess of a specified amount without prior shareholder approval.

In May 2021, we entered into an Open Market Sale AgreementSM, or the Sale Agreement, with Jefferies, LLC, or Jefferies, as agent, pursuant to which we may offer and sell ordinary shares, from time to time through Jefferies, by any method permitted that is deemed an "at the market offering" as defined in Rule 415(a)(4) promulgated under the Securities Act of 1933, as amended. Upon entry into the Sale Agreement, our existing ATM agreement with Jefferies entered into in June 2019 was terminated. We did not incur any termination penalties as a result of the replacement of the prior agreement with Jefferies. As of September 30, 2022, we have issued and sold an aggregate of 1,249,898 ordinary shares pursuant to the Sale Agreement and received gross proceeds of $33.5 million and net proceeds of $32.2 million, after deducting commissions to Jefferies and other offering expenses. From October 1, 2022 and through the date of this filing, we did not sell any shares under the Sale Agreement. As of the date of this filing, we may issue and sell ordinary shares for gross proceeds of up to $8.0 million under the New Sale Agreement.

On December 20, 2019, we issued 55,170 ordinary shares and accompanying warrants to purchase up to an aggregate of 55,170 ordinary shares. Each share was issued and sold together with an accompanying warrant at a combined price of $362.50 per security, that generated gross proceeds of $20.0 million and $18.3 million net, after deducting the placement agent's fees and offering expenses.

In March 2021, we entered into a securities purchase agreement with certain institutional investors pursuant to which we agreed to issue and sell in a registered direct offering (1) an aggregate of 390,440 ordinary shares, $0.01 nominal value per share, and accompanying warrants to purchase up to an aggregate of 195,220 ordinary shares and (2) pre-funded warrants to purchase up to an aggregate of 24,000 ordinary shares and accompanying ordinary share warrants to purchase up to an aggregate of 12,000 ordinary shares. Each share was issued and sold together with an accompanying ordinary share warrant at a combined price of $61.31, and each pre-funded warrant was issued and sold together with an accompanying ordinary share warrant at a combined price of $61.06. The proceeds to us from the offering were $25.4 million gross and $23.4 million net after deducting the placement agent's fees and estimated offering expenses. Each pre-funded warrant had an exercise price per ordinary share equal to $0.01 and each pre-funded warrant was exercised in full on the issuance date. Each ordinary share warrant has an exercise price per ordinary share equal to $59.75, was exercisable on the date of issuance and will expire on the five-year anniversary of the date of issuance.

Cash Flows

The following table summarizes our cash flows for the nine months ended September 30, 2022 and 2021:



                                                          Nine Months Ended September 30,

Operating Activities

Cash flow used in operating activities for the nine months ended September 30, 2022 was $35.1 million compared to $53.4 million for the nine months ended September 30, 2021, representing a 34% decrease. The $18.3 million decrease was primarily due to a $0.8 million decrease in net loss, after adjustments for the impact of non-cash amounts included in net loss in both periods, and by lower working capital of $17.6 million primarily due to decreases in accounts receivable and decreases in inventory, offset by decreases in accounts payable, accrued expenses and other liabilities.

Investing Activities

Cash flow used in investing activities was primarily for the purchase of property and equipment and was $0.3 million for the nine months ended September 30, 2022 and less than $0.1 million for the nine months ended September 30, 2021.

Financing Activities

Cash flow generated from financing activities for the nine months ended September 30, 2022 was $2.5 million net of transaction costs from our Purchase Agreement with Lincoln Park, as well as our Sale Agreement, offset by repayments of unexercised warrant nominal values and long-term debt. Cash flow generated from financing activities for the nine months ended September 30, 2021 was $64.2 million from our March 2021 financing, as well as our prior ATM agreement with Jefferies.

Material Cash Requirements

We expect to continue to incur significant expenses related to product sales, marketing, distribution and manufacturing. In addition, our expenses will increase if we suffer any regulatory delays or are required to conduct additional clinical trials to satisfy regulatory requirements.

In addition, our expenses will increase if and as we:

? initiate or continue the development of XENLETA and CONTEPO for additional

indications and of our other product candidates;

? seek to develop additional product candidates;

? seek marketing approval for any product candidates that successfully complete

clinical development;

? are required by the FDA, EMA or other regulators to conduct additional clinical

trials prior to or after approval;

continue to build or re-build a medical affairs, sales, marketing and

? distribution infrastructure and scale up manufacturing capabilities to

commercialize SIVEXTRO, XENLETA and any other product candidates for which we

receive marketing approval;

? in-license or acquire other products, product candidates or technologies,

including additional community products;

? maintain, expand and protect our intellectual property portfolio;

? expand our physical presence in the United States and Ireland;

? incur additional debt;

? establish and expand manufacturing arrangements with third parties; and

add operational, financial and management information systems and personnel,

? including personnel to support our product development and our operations as a

public company in addition to our commercialization efforts.

As described above, on March 11, 2020, we entered into a Third Amendment to our Loan Agreement with Hercules. Pursuant to the Third Amendment, we repaid to Hercules in March 2020, $30.0 million of the $35.0 million in



                                       37

Table of Contents

aggregate principal amount of debt outstanding under the Loan Agreement, which we refer to as the Prepayment. Under the Third Amendment, we and Hercules agreed to defer the end of term loan charge payment in the amount of approximately $2.1 million that would have otherwise become payable on the date of the Prepayment and to reduce the prepayment charge with respect to the Prepayment from $600,000 to $300,000 and to defer its payment, in each case, until June 1, 2023 or such earlier date on which all loans under the Loan Agreement are repaid or become due and payable. The Third Amendment also reset the revenue performance covenant to 70% of targeted revenue based on a revised net product revenue forecast and lowered our minimum liquidity requirement to $3.0 million in cash and cash equivalents, in each case, following the Prepayment. The new minimum liquidity requirement will not apply if CONTEPO receives regulatory approval from the U.S. Food and Drug Administration and we achieve at least 70% of our revised net product revenue targets under the Loan Agreement. On June 2, 2021, we entered into a further amendment, or the Fourth Amendment, to our Loan Agreement with Hercules. Pursuant to the Fourth Amendment, the date on which we must commence repaying principal under the Loan Agreement was extended to April 1, 2022. We began making interest and principal payments in April 2022. In addition, pursuant to the Fourth Amendment, the minimum liquidity requirement of $3.0 million in cash and cash equivalents will be waived at any time we have recognized $15.0 million of net product revenue during the applicable trailing three months. Based on our current operating plans, we expect that our existing cash, cash equivalents and restricted cash as of the date of this Quarterly Report on Form 10-Q, together with our anticipated SIVEXTRO and XENLETA commercial sales receipts, will be sufficient to enable us to fund our operations, debt service obligations and capital expenditure requirements into the first quarter of 2023. We have based this estimate on assumptions that may prove to be wrong, and we could use our capital resources sooner than we currently expect. This estimate assumes, among other things, that we do not obtain any additional funding through grants and clinical trial support, collaboration agreements, or equity or debt financings. This estimate also assumes that we remain in compliance with the covenants and no event of default occurs under the Loan Agreement.

Our future capital requirements will depend on many factors, including:

? the costs and timing of process development and manufacturing scale-up

activities associated with XENLETA and CONTEPO;

? the costs to secure supply of SIVEXTRO and costs to sell and market the product

in the U.S.;

? the costs, timing and outcome of regulatory review of lefamulin in Europe and

for any other indications and CONTEPO;

the costs of commercialization activities for SIVEXTRO, XENLETA and potentially

CONTEPO if we receive marketing approval, including the costs and timing of

? establishing product sales, marketing, distribution and outsourced

manufacturing capabilities, including the costs of building finished product

inventory and its components in preparation of initial marketing of CONTEPO, if

approved;

? the commercial success of SIVEXTRO and XENLETA and the amount and frequency of

reorders or product returns by our wholesale customers;

? subject to the resubmission of the CONTEPO NDA and potential receipt of

marketing approval, revenue received from commercial sales of CONTEPO;

? the costs of developing XENLETA and CONTEPO for the treatment of additional

indications;

? the impact of the COVID-19 pandemic;

? our ability to establish collaborations on favorable terms, if at all;

? the scope, progress, results and costs of product development of any other

product candidates that we may develop;




                                       38

  Table of Contents

? the extent to which we in-license or acquire rights to other products, product

candidates or technologies, including additional community products;

? the costs related to the promotion, sale and distribution of the products under

our distribution agreement with Merck & Co., Inc.;

the costs of preparing, filing and prosecuting patent applications, maintaining

? and protecting our intellectual property rights and defending against

intellectual property-related claims;

? the continued availability of Austrian governmental grants;

? the need to satisfy interest and principal obligations under our Loan Agreement

with Hercules as well as the covenants contained in our Loan Agreement;

? the rate of the expansion of our physical presence in the United States and

Ireland; and

? the costs of operating as a public company in the United States.

Our commercial revenues, if any, will be derived from sales of SIVEXTRO, XENLETA, and if approved, CONTEPO or any other products that we successfully develop, in-license or acquire. In addition, SIVEXTRO, XENLETA and, if approved, CONTEPO or any other product candidate that we develop, in-license or acquire may not achieve commercial success. Accordingly, we will need to obtain substantial additional financing to achieve our business objectives. We may also consider potential strategic transactions, including the potential sale, license or other disposition of one or more of our assets, including XENLETA and CONTEPO and have retained Torreya Capital to advise on our expoloration of the strategic options available to us. Adequate additional financing may not be available to us on acceptable terms, or at all, and we may not be able to consummate a strategic sale, license or other disposition of one or more of our assets on acceptable terms should we choose to pursue such a transaction, or at all. In addition, we may seek additional capital due to favorable market conditions or strategic considerations, even if we believe that we have sufficient funds for our current or future operating plans.

Until such time, if ever, as we can generate substantial product revenues, we expect to finance our cash needs through a combination of equity offerings, debt financings, collaborations, and funding from local and international government entities and non-government organizations in the disease areas addressed by our product candidates and marketing, distribution or licensing arrangements. We may also finance our cash needs by selling, licensing or disposing of one or more of our assets, including XENLETA and CONTEPO. To the extent that we raise additional capital through the sale of equity, warrants or convertible debt securities, the ownership interest of our shareholders will be diluted, and the terms of these securities may include liquidation or other preferences that adversely affect the rights of our existing shareholders. Additional debt financing, if available, may involve agreements that include covenants limiting or restricting our ability to take specific actions, such as incurring additional debt, making capital expenditures or declaring dividends.

If we raise additional funds through asset sales, collaborations, strategic alliances or marketing, distribution or licensing arrangements with third parties, we may have to relinquish valuable rights to our technologies, future revenue streams, research programs or product candidates or to grant licenses on terms that may not be favorable to us. If we are unable to raise additional funds through equity or debt financings when needed, we may be required to delay, limit, reduce or terminate our product development or future commercialization efforts or grant rights to develop and market product candidates that we would otherwise prefer to develop and market ourselves. If we are unable to raise capital when needed or consummate a strategic sale, license or other disposition of one or more of our assets (should we choose to pursue such a transaction), then we may be forced to delay, reduce or eliminate our commercialization efforts, conduct additional reductions-in-force or cease our operations and, potentially, wind down the company under the bankrupty laws or otherwise. If we were to cease operations and wind down the company under the bankruptcy laws or otherwise, we cannot assure our shareholders or other stakeholders of any specific level of recovery, or any recovery at all on their specific claims or interest.

  Table of Contents

In addition, as part of our corporate strategy, we continue to evaluate business development opportunities and potential collaborations. We may further expand our product pipeline through opportunistically purchasing in-licensing or acquiring the rights to complementary products, product candidates and technologies for the treatment of a range of infectious diseases or other products that we would market with our commercial infrastructure, including additional community products, which could involve an acquisition of or business combination or other strategic transaction with another operating business. To the extent any additional business development opportunity is consummated, our capital expenditures may increase significantly.

We have contractual commitments related primarily to contracts entered into with contract manufacturing organizations and contract research organizations in connection with the commercial manufacturing of XENLETA, the purchase of SIVEXTRO finished product and other research and development activities. The contractual commitments are further described in Note 15 to our consolidated financial statements included in our Annual Report on Form 10-K for the year ended December 31, 2021 and in Note 12 to our consolidated financial statements included elsewhere in this Quarterly Report on Form 10-Q.

Capital Expenditures

Capital expenditures were $0.2 million and $20,000 for the nine months ended September 30, 2022 and 2021, respectively. Currently, there are no material capital projects planned in 2022.
