assumptions do not turn out to be substantially accurate, even if such assumptions are reasonable when made. In our condensed financial statements, estimates and assumptions relied upon are used for, but not limited to, the value of accrued clinical trial costs, measurement of fair value of equity instruments, and stock-based compensation expense. We evaluate our estimates and assumptions on the ongoing basis. Actual results could differ from those estimates under different assumptions or conditions.

Warrant Liability Accounting

We issued a warrant for the purchase of Series A preferred shares to the Lender in connection with the Loan and Security Agreement (see Note 6) and classified the warrant as a liability in accordance with authoritative guidance. We recorded the initial warrant liability at the fair market value as of the issuance date, with subsequent re-measurement as of each reporting period, using the Black-Scholes valuation model which includes a risk-free interest rate, expected term and volatility assumptions derived from comparable companies in the biotechnology industry whose share prices are publicly available for a sufficient period of time. The expected life of the warrant was calculated using the remaining life of the warrant. The risk-free rate is based upon U.S. Treasury securities with remaining terms similar to the expected term of the warrant being valued. Changes in fair value of the warrant liability are calculated at the end of each reporting period using the Black-Scholes pricing model and are recorded as other income (expense). We will continue to adjust the carrying value of the warrant for changes in the estimated fair value until the earlier of the modification, exercise or expiration of the warrant. At that time, the liabilities will be reclassified to additional paid-in capital, a component of stockholders’ deficit.

2.                                       Fair Value Measurements

The carrying values of our financial instruments such as cash and cash equivalents, prepaid expenses and other, accounts payable, and accrued expenses, and accrued compensation approximate their respective fair values because of the short-term nature of those financial instruments. Based on the borrowing rates currently available to us for loans with similar terms, we believe the carrying amounts of the term loan, approximate its fair value.  The preferred stock warrant liability is recorded at fair value.

The fair value of cash equivalents was determined based on Level 1 inputs utilizing quoted prices in active markets. The fair value of our preferred stock warrant liability was determined based on Level 3 inputs using a valuation model with significant unobservable inputs (see Note 6). The following tables present the assets and liabilities measured at fair value and classified by level according to the fair value measurement hierarchy:

The following table reconciles liabilities measured at fair value using significant unobservable events (Level 3) for the six months ended June 30, 2018:

3.                                       Stock Purchase Agreement and Merger

In May 2015, the Selling Stockholders entered into a Stock Purchase Agreement (SPA) with SGP, pursuant to which SGP acquired all of the outstanding capital stock of ZTI from the Selling Stockholders. As consideration for the acquisition, SGP paid $400 in cash and issued 1,420,000 shares of SGP common stock to the Selling Stockholders on a pro rata basis, both of which were expensed as purchased in-process research and development. In addition to the closing consideration, we (as successor to SGP) are obligated to make: (i) additional milestone payments totaling up to $30,500, which include (a) $1,500 paid in April 2016 upon the closing of the Series A preferred stock financing (see Note 6), which was expensed as purchase in-process research and development, (b) $3,000 payable upon the marketing approval by the U.S. Food and Drug Administration (FDA) with respect to any oral, intravenous or other form of fosfomycin (the Fosfomycin Products), and (c) $26,000 in milestone payments  upon the occurrence of various specified levels of net sales with respect to the Fosfomycin Products; and (b) single digit tiered royalties on net sales of our Fosfomycin Products. Our obligation to pay such royalties will be reduced by 50%, on a country-by-country basis, if and when a generic competitive product accounts for half of the market for such Fosfomycin Product in each country. Given the early-stage nature of ZTI, we accounted for the SPA as an asset acquisition.

In June 2015, SGP, as the sole shareholder of ZTI, merged into ZTI and we became the surviving company.

Loan and Security Agreement

In August 2016, we entered into a $10,000 term loan and security agreement (the Loan Agreement) with Square 1 Bank, a division of Pacific Western Bank (the Lender) to provide growth capital to us. As of June 30, 2018, $10,000 was outstanding and no additional funds were available. The credit facility bears interest based on the greater of 5% or Prime + 1.5% (6.5% as of June 30, 2018), payable monthly. The terms include an interest-only period through August 2018, followed by equal monthly payments of principal and interest over the remaining 24-month term. The loans are collateralized by substantially all of our assets, excluding intellectual property, which are subject to a negative pledge. On July 23, 2018, in connection with the Merger Transaction (see Note 8), we repaid the loan balance in full immediately prior to the closing.

Notes to Condensed Financial Statements (continued)

In April 2017, in connection with the initial funding under the Loan Agreement, we issued to the Lender a fully exercisable warrant to purchase 185,185 shares of our Series A preferred stock at an exercise price of $1.35 per share. The warrant expires on August 5, 2026. If the warrant has not been exercised prior to its expiration date, it will be deemed to automatically convert by “cashless” conversion. In the event we are acquired, the warrant will be exercisable or deemed automatically converted, which shall be determined based upon whether our successor assumes the obligations of the warrant.

Future maturities of long-term debt and interest payments and unamortized discount balances under the credit facility are as follows (in thousands):

Convertible Series A Preferred Stock

In March 2016, we completed a Series A convertible preferred stock (Series A preferred stock) financing, providing us with $35,000 in aggregate gross proceeds, net of $404 of issuance costs, from the issuance of 25,925,924 shares of Series A preferred stock at $1.35 per share. Included in the closing of the Series A preferred stock financing was the conversion of convertible notes payable and accrued interest of $10,732 for 9,936,790 shares of Series A preferred stock. Such notes converted at a 20% discount from the $1.35 Series A per share issuance price, which resulted in the recording of a $2,683 beneficial conversion feature noncash charge through additional paid-in capital and interest expense. In aggregate, 35,862,714 shares of Series A preferred stock were issued.

The Series A preferred stock have the following characteristics:

Notes to Condensed Financial Statements (continued)

Dividends

The holders of the Series A preferred stock are entitled to receive non-cumulative dividends at a rate of $0.108 per share per annum. Preferred stock dividends are payable, in preference and in priority to any dividends on common stock, when and if declared by our Board of Directors. As of June 30, 2018, our Board of Directors has not declared any dividends.

Liquidation

In the event of any liquidation, dissolution, or winding up of our operations, the holders of Series A preferred stock will be entitled to receive in preference to the holders of common stock, the amount of $1.35 per share, plus declared and unpaid dividends, if any. Thereafter, any or our remaining assets will be distributed ratably among the holders of the common stock and preferred stock, with the preferred stock limited to $4.05 per share, based upon the number of shares of common stock held by each stockholder, treating each share of preferred stock as if it were converted into shares of common stock at the then-applicable conversion rate.

If the assets and funds available to be distributed among the holders of the Series A preferred stock shall be insufficient to permit the payment of $1.35 per share, then the entire assets and funds legally available for distribution to such holders shall be distributed ratably based on the total Series A preferred stock holdings of each such holder.

Conversion and Voting

The shares of Series A preferred stock are convertible into an equal number of shares of common stock, at the option of the holder, subject to certain antidilutive adjustments. Each share of Series A preferred stock is automatically converted into common stock immediately upon the earlier of: (i) the sale of our common stock in a firm commitment underwritten public offering pursuant to a registration statement under the Securities Act of 1933, as amended, in which the per share price is at least $4.05 per share (as adjusted), and the gross cash proceeds are at least $40,000, or (ii) the date specified by written consent or agreement of the holders of not less than 50% of the then outstanding shares of preferred stock.

The holders of Series A preferred stock are entitled to one vote for each share of common stock into which such Series A preferred stock could then be converted; and with respect to such vote, such holder shall have full voting rights and powers equal to the voting rights and powers of the holders of common stock. Also, the Series A preferred stockholders have been granted certain rights with regard to the election of members of our Board of Directors and various other corporate actions.

2015 Equity Incentive Plan

In August 2015, we adopted the Zavante Therapeutics, Inc. 2015 Equity Incentive Plan (the 2015 Plan). As amended in March 2016, the 2015 Plan provides for the issuance of incentive stock options to our employees and nonstatutory stock options and restricted stock awards, in the form of a restricted stock bonus or a restricted stock purchase right, to our employees, directors, and consultants. As of June 30, 2018, we had 5,534,750 shares available for issuance under the 2015 Plan.

The following table summarizes stock option activity for the six months ended June 30, 2018:

7.                                       COMMITMENTS AND CONTINGENCIES

Corporate Office Lease Obligation

Effective as of June 2016, we signed a non-cancellable three-year operating lease for our corporate office facility. The lease provides for the aggregate minimum lease payments totaling $341, and provides us an option to extend the lease at the end of the original term for a three-year period. Rent expense for the six months ended June 30, 2018 and 2017 was $57. We paid the landlord a security deposit of $10, which is included in other assets in the condensed balance sheet as of June 30, 2018.

As of June 30, 2018, the future minimum rent payments under the operating lease are as follows:

Manufacturing and Supply Agreements

In 2014, we entered into: (i) a Pharmaceutical Manufacturing and Exclusive Supply Agreement with Laboratorios ERN, S.A. (ERN) for the exclusive supply of fosfomycin disodium and succinic acid injection for intravenous use filled, finished and packaged into containers for use by end users (Product) for sale in the United States, and (ii) a Three-Way Agreement with ERN and Ercros, S.A. (Ercros) for the supply of technical documentation, expertise and know-how in connection with the submission of a new drug application or an abbreviated new drug application, as applicable (collectively, NDA), for the Product. In 2016, we concurrently entered into: (i) an Amended and Restated Three-Way Agreement with ERN and Ercros, (ii) an Amended and Restated Pharmaceutical Manufacturing and Exclusive Supply

Zavante Therapeutics, Inc.

Notes to Condensed Financial Statements (continued)

Agreement (ERN Agreement), both of which allowed for removing the responsibility for ERN to provide commercial Product and allow us to take direct responsibility for the manufacture and supply of commercial Product with separate third-party manufacturers, and (iii) an exclusive supply agreement with Ercros for the supply of a blend of fosfomycin disodium and succinic acid at a fixed price for the first five (5) years under the agreement. Each of the agreements provide for an initial term of 10 years with automatic renewals of two (2) years for successive terms.

The ERN Agreement, as amended further through December 20, 2017, provides that: (i) ERN has development responsibilities with financial obligations not to exceed $1,000, which was met during the six months ending June 30, 2018, (ii) a milestone payment of $100 to ERN triggered upon our first commercial sale, (iii) a quarterly payment to ERN for each vial sold, payable in arrears, and (iv) an indemnification payment to ERN under certain circumstances as outlined therein.

In connection with ERN’s development responsibilities, as of June 30, 2018, we have incurred reimbursable costs of $257 which are included in prepaid expenses and other. All of such reimbursable costs were collected in July 2018.

In July 2016 and April 2017, we entered into separate manufacturing and supply agreements with Antibioticos do Brasil Ltda (ABL) and Fisiopharma S.r.l (Fisiopharma), respectively, under which each party has agreed to validate and supply fosfomycin disodium for intravenous injection in bulk drug vials (the Bulk Drug Vials) to us. Each agreement has an initial term of ten years with automatic renewals of one (1) year for successive terms thereafter. To the extent that both suppliers are in compliance with governing regulatory requirements for manufacturers at the time we commence the sale of our product, then we will be obligated to purchase half of our future commercial requirements of Bulk Drug Vials for the United States from each party. In connection with such agreements, we have engaged in certain technology transfer activities. There were no significant commitments outstanding under the ABL or Fisiopharma agreements as of June 30, 2018.

8.                    SUBSEQUENT EVENTS

Subsequent events are events or transactions that occur after the condensed financial statement date, but before the condensed financial statements are issued. We recognize in the accompanying condensed financial statements the effects of all subsequent events that provide additional evidence about conditions that existed at the date of the audit report, including the estimates inherent in the process of preparing the condensed financial statements. Our condensed financial statements do not recognize subsequent events that provide evidence about conditions that did not exist at the balance sheet date, but arose after the condensed financial statement date and before the condensed financial statements are issued.

We evaluated the subsequent events through July 24, 2018, the date on which these condensed financial statements were available to be issued.

Merger with Nabriva Therapeutics

In July 2018, we were acquired by Nabriva Therapeutics for: (i) upfront consideration of approximately 8.2 million of Nabriva Therapeutics’ ordinary shares (which includes an indemnity holdback), and (ii) potential future milestone payments up to $97.5 million in contingent consideration, of which $25.0 million would become payable upon the first approval of an NDA from the FDA for fosfomycin for injection for any indication and an aggregate of up to $72.5 million would become payable upon the achievement of specified sales milestones.

Immediately prior to or contemporaneous with the closing of the acquisition, the following occurred: (i) we repaid the loan balance under the Loan Agreement in full prior to the closing, (ii) the unvested restricted common shares or stock options outstanding were accelerated and immediately vested upon the closing of the transaction, and (iii) certain transaction expenses incurred in connection with the acquisition were assumed by Nabriva Therapeutics.

Exhibit 99.4

UNAUDITED PRO FORMA COMBINED FINANCIAL INFORMATION

On July 23, 2018, Nabriva Therapeutics plc (the “Company” or “Nabriva”) and its newly formed, direct wholly owned subsidiaries, Zuperbug Merger Sub I, Inc. (“Merger Sub I”) and Zuperbug Merger Sub II, Inc. (“Merger Sub II”, and together with Merger Sub I, “Merger Subs”) entered into an Agreement and Plan of Merger (the “Merger Agreement”) with Zavante Therapeutics, Inc. (“Zavante”) and Cam Gallagher, solely in his capacity as representative of the former Zavante stockholders in connection with the Merger Agreement, pursuant to which on July 24, 2018, Merger Sub I merged with and into Zavante with Zavante surviving such merger and becoming a wholly owned subsidiary of the Company, and Zavante thereafter on such date merged with and into Merger Sub II, with Merger Sub II surviving the merger as a wholly owned subsidiary of the Company and assuming the name Zavante Therapeutics, Inc. (collectively, the “Acquisition”).  The Acquisition was completed on July 24, 2018 (the “Closing”).

The unaudited pro forma combined financial statements presented below are based on, and should be read together with, the historical information that the Company has presented in its filings with the Securities and Exchange Commission. The unaudited pro forma combined balance sheet as of June 30, 2018 gives effect to the Acquisition as if it had occurred on June 30, 2018, and combines the historical balance sheets of the Company and Zavante as of June 30, 2018. The unaudited pro forma combined statements of operations for the year ended December 31, 2017 and for the six months ended June 30, 2018 are presented as if the Acquisition of Zavante had occurred on January 1, 2017, and combines the historical results of the Company and Zavante for the year ended December 31, 2017 and for the six months ended June 30, 2018. The historical financial information is adjusted to give effect to pro forma events that (i) are directly attributable to the Acquisition, (ii) are factually supportable and (iii) with respect to the statements of operations, must be expected to have a continuing impact on the combined results.

The pro forma adjustments related to the Acquisition are based on a preliminary purchase price allocation whereby the cost to acquire Zavante was allocated to the assets acquired and the liabilities assumed, based upon their estimated fair values. The final purchase price allocation will be performed using estimated fair values as of the date of the Acquisition. Differences between the preliminary and final purchase price allocations could have a material impact on the accompanying unaudited pro forma combined financial statements and the Company’s future results of operations and financial position.

The unaudited pro forma combined financial statements do not reflect the realization of potential cost savings, or any related restructuring or integration costs. Although the Company believes that certain cost savings may result from the Acquisition, there can be no assurance that these cost savings will be achieved.

The unaudited pro forma combined financial statements are presented for illustrative purposes only and are not necessarily indicative of the consolidated financial position or results of operations in future periods or the results that actually would have been realized if the Acquisition had been completed as of the dates indicated. As a result, the actual financial condition and results of operations of the Company following the Acquisition may not be consistent with, or evident from, these pro forma combined financial statements. In addition, the assumptions used in preparing the pro forma financial information may not prove to be accurate, and other factors may affect the Company’s financial condition or results of operations following the Acquisition.
