Liquidity and Capital Resources
In the course of our development activities, we have sustained operating losses and expect such losses to continue over the next several years. We expect to continue to incur significant expenses and operating losses for the foreseeable future as we continue to develop, conduct clinical trials and seek regulatory approval for our product candidates. Our primary uses of capital are, and we expect will continue to be, compensation and related expenses, third-party clinical research and development services, contract manufacturing services, laboratory and related supplies, clinical costs, legal and other regulatory expenses and general overhead costs.
If we obtain regulatory approval for any of our product candidates, we expect to incur significant commercialization expenses. We do not have a sales, marketing, manufacture or distribution infrastructure for a pharmaceutical product. To develop a commercial infrastructure, we will have to invest financial and management resources, some of which would have to be deployed prior to having any certainty of marketing approval.
We had unrestricted cash and cash equivalents of $28.7 million as of September 30, 2021. Our existing cash and cash equivalents as of September 30, 2021 will be used primarily to fund the Phase 3 trial of INOpulse for fILD and to complete the dose escalation study for PH-Sarc.
On April 1, 2020, we completed the sale of 1,275,000 shares of our common stock in a registered direct offering at an offering price of $12.00 per share, resulting in net proceeds of approximately $14.1 million, after deducting agent fees of $1.1 million and offering costs of $0.1 million. Such shares were sold pursuant our effective shelf registration statement on Form S-3.
On May 22, 2020, we completed the sale of 3,365,384 shares of our common stock in a public offering and concurrent registered direct offering including a full exercise of an option to purchase additional shares at a price of $13.00 per share, resulting in net proceeds of approximately $40.6 million, after deducting agent fees of $2.9 million and offering costs of $0.3 million. The agent fees included a financial advisory fee of $900,000 to Angel Pond Capital LLC, a company affiliated with Theodore Wang, a member of our board of directors. Such shares were sold pursuant to our prior shelf registration statement on Form S-3.
On June 26, 2020, we filed a shelf registration statement on Form S-3 with the SEC, which became effective on July 2, 2020. The shelf registration allows us to issue, from time to time at prices and on terms to be determined prior to the time of any such offering, up to $150 million of any combination of common stock, preferred stock, debt securities, warrants and rights, either individually or in units.
In July 2020, we entered into an Open Market Sale AgreementSM with Jefferies LLC, as sales agent, pursuant to which we may offer and sell shares of its common stock, from time to time, for an aggregate sales price of up to $40.0 million through an “at the market offering” program under a shelf registration statement on Form S-3. To date, we have not sold any shares under this agreement.
The State of New Jersey’s Technology Business Tax Certificate Transfer Program enables qualified, unprofitable New Jersey based technology or biotechnology companies to sell a percentage of NOL and R&D tax credits to unrelated profitable corporations, subject to meeting certain eligibility criteria. Based on consideration of various factors, including application processing time and past trend of benefits made available under the program, we believe that it is probable that our plans to sell our NOLs can be effectively implemented to address our short term financial needs. We have sold $16.3 million of state NOLs and $0.3 million of research and development tax credits under the State of New Jersey’s Technology Business Tax Certificate Transfer Program in June 2021 for net proceeds of $1.7 million and has sold an additional $21.2 million of state NOLs and $0.2 million of research and development tax credits for net proceeds of $1.7 million in May 2020. We plan to sell additional NOLs and R&D credits under the same program in the future subject to program availability and state approval. The proceeds from such sales are recorded as Income tax benefit when sales occur or proceeds are received.
