is commercially available. XENLETA, SIVEXTRO or, if approved, CONTEPO or any other product candidate that we develop, in-license or acquire may not achieve commercial success. Additionally, the termination of our sales force may adversely impact our sales of XENLETA. If we fail to generate sufficient revenues from the sale of XENLETA, SIVEXTRO or the commercialization of CONTEPO or any other product candidate that we successfully develop, in-license or acquire, we will need to obtain substantial additional financing to achieve our business objectives.
Adequate additional financing may not be available to us on acceptable terms, or at all.
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 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 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.
Raising additional capital may cause dilution to our security holders, restrict our operations or require us to relinquish certain rights to our technologies, products or product candidates.
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 products or product candidates and marketing, distribution or licensing arrangements. To the extent that we raise additional capital through the sale of equity or convertible debt securities, our security holders’ ownership interests will be diluted, and the terms of these securities may include liquidation or other preferences that adversely affect the rights of our security holders. 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. In addition, debt service obligations under any debt financings may limit the availability of our cash for other purposes, and we may be unable to make interest payments or repay the principal of such debt financings when due.
On June 25, 2019, we entered into an Open Market Sale AgreementSM, or the Jefferies ATM Agreement, with Jefferies LLC, or Jefferies, as agent, pursuant to which we may offer and sell ordinary shares, nominal value $0.01 per share, for aggregate gross sale proceeds of up to $50.0 million from time to time through Jefferies under an “at-the-market” offering program. As of the date of this filing, we have issued and sold an aggregate of 13,117,034 ordinary shares under the Jefferies ATM Agreement, for gross proceeds of $18.0 million, and net proceeds of $17.2 million, after deducting commissions and offering costs. We previously entered into a Controlled Equity Offering SM Sales Agreement, or the Cantor ATM Agreement, with Cantor Fitzgerald & Co. that we terminated effective as of June 24, 2019. The approximately $12.2 million of ordinary shares that had been available for sale pursuant to the Cantor ATM Agreement remained unsold at the time of its termination. If a large number of our ordinary shares is sold in the public market after they become eligible for sale or if we make additional sales under our “at-the-market” offering program, the sales could cause dilution to our security holders, reduce the trading price of our ordinary shares and impede our ability to raise future capital.
On May 29, 2020, we entered into a securities purchase agreement with certain institutional investors, including Fidelity Management & Research Company, LLC pursuant to which we issued and sold in a registered direct offering an aggregate of 41,445,373 ordinary shares and accompanying warrants to purchase up to an aggregate of 41,445,373 ordinary shares. Each share we issued and sold together with an accompanying warrant at a combined price of $0.91686. The gross proceeds to us from the offering, before deducting the placement agent’s fees and other offering expenses payable by the Company were $38.0 million. Each warrant has an exercise price of $0.792 per share, was immediately exercisable and will expire on the two-year anniversary of the exercise date.
In addition, in connection with the closing of the Acquisition, we issued 7,336,906 of our ordinary shares to former Zavante stockholders as initial upfront consideration and following the one year anniversary of the closing of the Acquisition on July 25, 2019, we issued an additional 815,186 ordinary shares to the former Zavante stockholders that
