1. Organization

Pulmatrix, Inc. and its subsidiaries (the “Company”) is a clinical stage biotechnology company focused on the discovery and development of a novel class of inhaled therapeutic products. The Company’s proprietary dry powder delivery platform, iSPERSE™ (inhaled Small Particles Easily Respirable and Emitted), is engineered to deliver small, dense particles with highly efficient dispersibility and delivery to the airways, which can be used with an array of dry powder inhaler technologies and can be formulated with a variety of drug substances. The Company is developing a pipeline of iSPERSE-based therapeutic candidates targeted at prevention and treatment of a range of respiratory diseases and infections with significant unmet medical needs.

Liquidity

At June 30, 2018, the Company had unrestricted cash and cash equivalents of $8,341, an accumulated deficit of $185,411 and working capital of $5,182. The Company will be required to raise additional capital by the end of 2018 to continue the development and commercialization of current product candidates and to continue to fund operations at the current cash expenditure levels.

The Company cannot be certain that additional funding will be available on acceptable terms, or at all. To the extent that the Company raises additional funds by issuing equity securities, the Company’s stockholders may experience significant dilution. Any debt financing, if available, may involve restrictive covenants that impact the Company’s ability to conduct business. If unable to raise additional capital when required or on acceptable terms, the Company may have to (i) delay, scale back or discontinue the development and/or commercialization of one or more product candidates; (ii) seek collaborators for product candidates at an earlier stage than otherwise would be desirable and on terms that are less favorable than might otherwise be available; or (iii) relinquish or otherwise dispose of rights to technologies, product candidates or products that the Company would otherwise seek to develop or commercialize on unfavorable terms.

During the six months ended June 30, 2018, the Company issued 25,879,723 shares of common stock as the result of the sale of 24,647,061 shares of common stock pursuant to an underwritten public offering and the exercise of pre-funded warrants also issued in such offering and 1,232,662 shares of common stock related to the At-the-Market Offering sales agreement. The Company received aggregate net proceeds of $16,372 in connection with the foregoing (Note 7).

The Company’s ability to continue as a going concern is dependent upon its ability to obtain additional equity or debt financing and, ultimately, to generate revenue. Those factors raise substantial doubt about the Company’s ability to continue as a going concern within one year from the date of filing these condensed consolidated financial statements. The Company’s condensed consolidated financial statements as of June 30, 2018 do not include any adjustments that might become necessary should the Company be unable to continue as a going concern.

2. Basis of Presentation

The accompanying unaudited condensed consolidated financial statements of the Company have been prepared on a going concern basis in accordance with accounting principles generally accepted in the United States (“GAAP”) for interim financial reporting and as required by Regulation S-X, Rule 10-01. Accordingly, they do not include all of the information and footnotes required by GAAP for complete financial statements. In the opinion of management, all adjustments (including those which are normal and recurring) considered necessary for a fair presentation of the interim financial information have been included. When preparing financial statements in conformity with GAAP, the Company must make estimates and assumptions that affect the reported amounts of assets, liabilities, revenues, expenses and related disclosures at the date of the financial statements. Actual results could differ from those estimates. Additionally, operating results for the three months and six months ended June 30, 2018, are not necessarily indicative of the results that may be expected for any other interim period or for the fiscal year ending December 31, 2018. For further information, refer to the financial statements and footnotes included in the Company’s annual financial statements for the fiscal year ended December 31, 2017, which are included in the Company’s annual report on Form 10-K filed with the SEC on March 13, 2018.

3. Summary of Significant Accounting Policies

In the three and six months ended June 30, 2018, there were no changes to the Company’s significant accounting policies identified in the Company’s most recent annual financial statements for the fiscal year ended December 31, 2017, which are included in the Company’s annual report on Form 10-K filed with the SEC on March 13, 2018, except as noted below.

Recent Accounting Pronouncements

In June 2018, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) No. 2018-07, Compensation—Stock Compensation (Topic 718): Improvements to Nonemployee Share-Based Payment Accounting. Subtopic 505-50, Equity—Equity-Based Payments to Non-Employees, addresses aspects of the accounting for nonemployee share based compensation. The amendments are effective for public business entities for fiscal years beginning after December 15, 2018, including interim periods within that fiscal year. The Company is currently evaluating the potential impact of adopting this guidance on its condensed consolidated financial statements.

In March 2018, the FASB issued ASU No. 2018-05, “Amendments to SEC Paragraphs Pursuant to SEC Staff Accounting Bulletin No. 118”, (“ASU 2018-05”) to add various SEC paragraphs pursuant to the issuance of SEC Staff Accounting Bulletin No. 118 (“SAB 118”), to ASC 740 “Income Taxes”. SAB 118 was issued by the SEC in December 2017 to provide immediate guidance for accounting implications of U.S. tax reform under the “Tax Cuts and Jobs Act” (the “Tax Act”), which became effective for the Company on January 1, 2018. The Company has adopted ASU 2018-05 and adoption of this ASU has no significant impact on its condensed consolidated financial statements.

In February 2018, the FASB issued ASU No. 2018-02, “Income Statement — Reporting Comprehensive Income (Topic 220): Reclassification of Certain Tax Effects from Accumulated Other Comprehensive Income” (“ASU 2018-02”), which allows a reclassification from accumulated other comprehensive income to retained earnings for stranded tax effects resulting from the Tax Act and requires certain disclosures about stranded tax effects. ASU 2018-02 is effective for us beginning December 1, 2019 (with early adoption permitted) and shall be applied either in the period of adoption or retrospectively to each period (or periods) in which the effect of the change in the corporate income tax rate in the Tax Act is recognized. The Company is currently evaluating the potential impact of adopting this guidance on its condensed consolidated financial statements.

In May 2014, the FASB issued ASU 2014-09, “Revenue from Contracts with Customers (Topic 606)” (“ASU 2014-09”). ASU 2014-09 supersedes the revenue recognition requirements in ASC Topic 605, “Revenue Recognition” and some cost guidance included in ASC Subtopic 605-35, “Revenue Recognition - Construction-Type and Production-Type Contracts.” The core principle of ASU 2014-09 is that revenue is recognized when the transfer of control of goods or services to customers occurs in an amount that reflects the consideration to which the Company expects to be entitled in exchange for those goods or services. ASU 2014-09 requires the disclosure of sufficient information to enable readers of the Company’s financial statements to understand the nature, amount, timing and uncertainty of revenue and cash flows arising from customer contracts. ASU 2014-09 also requires disclosure of information regarding significant judgments and changes in judgments, and assets recognized from costs incurred to obtain or fulfill a contract. ASU 2014-09 provides two methods of retrospective application. The first method would require the Company to apply ASU 2014-09 to each prior reporting period presented. The second method would require the Company to retrospectively apply ASU 2014-09 with the cumulative effect recognized at the date of initial application. Since the Company is an emerging growth company and elected to use the extended transition period for complying with any new or revised financial accounting standards provided pursuant to Section 13(a) of the Exchange Act, this ASU 2014-09 will be effective for the Company beginning in fiscal 2019 as a result of ASU 2015-14, “Revenue from Contracts with Customers (Topic 606): Deferral of the Effective Date,” which was issued by the FASB in August 2015 and extended the original effective date by one year. The Company is currently evaluating the impact of adopting the available methodologies of ASU 2014-09 and 2015-14 upon its consolidated financial statements in future reporting periods. The Company is also in the process of evaluating the new standard against its existing revenue recognition accounting policies to determine the effect the guidance will have on its condensed consolidated financial statements and what changes to systems and controls may be warranted.

Use of Estimates

In preparing consolidated financial statements in conformity with U.S. GAAP, management is required to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements, as well as the reported amounts of expenses during the reporting period. Due to inherent uncertainty involved in making estimates, actual results may differ from these estimates. On an ongoing basis, the Company evaluates its estimates and assumptions. These estimates and assumptions include valuing equity securities in share-based payments, estimating fair value of equity instruments recorded as derivative liabilities, estimating the useful lives of depreciable and amortizable assets, valuation allowance against deferred tax assets, goodwill impairment, and estimating the fair value of long-lived assets to assess whether impairment charges may apply.

Revenue Recognition

The Company’s principal sources of revenue during the reporting period were reimbursement of clinical study costs. In all instances, revenue is recognized only when the price is fixed or determinable, persuasive evidence of an arrangement exists, delivery has occurred or services have been rendered, and collectability of the resulting receivable is reasonably assured.

Goodwill

Goodwill represents the difference between the consideration transferred and the fair value of the net assets acquired, and liabilities assumed under the acquisition method of accounting for push-down accounting. Goodwill is not amortized but is evaluated for impairment within the Company’s single reporting unit on an annual basis, during the fourth quarter, or more frequently if an event

occurs or circumstances change that would more likely than not reduce the fair value of the Company’s reporting unit below its carrying amount. When performing the impairment assessment, the accounting standard for testing goodwill for impairment permits a company to first assess the qualitative factors to determine whether the existence of events and circumstances indicates that it is more likely than not that the goodwill is impaired. If the Company believes, as a result of the qualitative assessment, that it is more likely than not that the fair value of goodwill is impaired, the Company must perform a quantitative impairment test. The Company completed a qualitative assessment and determined that there was no impairment of goodwill as of June 30, 2018.

4. Prepaid Expenses and Other Current Assets

Prepaid expenses consisted of the following:

5. Debt

Loan and Security Agreement and Warrant Agreement

On June 11, 2015, Pulmatrix Operating entered into a Loan and Security Agreement (“LSA”) with Hercules Technology Growth Capital, Inc. (“Hercules”), for a term loan in a principal amount of $7,000 (“Term Loan”). The term loan was secured by substantially all of the Company’s assets, excluding intellectual property. Final payments were made in June 2018 and, as of June 30, 2018, the term loan was paid in full.

The term loan bore interest at a floating annual rate equal to the greater of (i) 9.50% and (ii) the sum of (a) the prime rate as reported by The Wall Street Journal minus 3.25% plus (b) 8.50%. The Company was required to make interest payments in cash on the first business day of each month, beginning on July 1, 2015. Since August 1, 2016, the Company has been required to make monthly payments on the first business day of each month consisting of principal and interest based upon a 30-month amortization schedule, and any unpaid principal and interest is due on the maturity date of July 1, 2018. Upon repayment of the term loan, the Company is also required to pay an end of term charge to the Lenders equal to $245. During the period, the Company prepaid the loan in its entirety, including the end of term charge. As the Company received a waiver for any prepayment fee associated with early payoff, no prepayment penalty was incurred. As of June 30, 2018, the company has no further liability to Hercules.

During the term of the loan, the Company could have elected to prepay all, but not less than all, of the outstanding principal balance of the term loan, subject to a prepayment fee of 1% – 3%, depending on the date of repayment. Contingent on the occurrence of several events, including that the Company’s closing stock price exceed $11.73 per share for the seven days preceding a payment date, the Company could have elected to pay, in whole or in part, any regularly scheduled installment of principal up to an aggregate maximum amount of $1,000 by converting a portion of the principal into shares of the Company’s common stock at a price of $11.73 per share. Hercules may have elected to receive payments in the Company common stock by requiring the Company to affect a conversion option whereby Hercules could have elected to receive a principal installment payment in shares of the Company common stock based on a price of $11.73 per share, subject to an aggregate maximum principal amount of $1,000.

Table of Contents

The Company determined that the Company’s provisions allowing conversion of all or a portion of the LSA contained a beneficial conversion feature (“BCF”). The BCF is contingent upon the occurrence of certain events and as such, the Company will not record the BCF until the contingency is resolved. As the conversion feature was not executed during the life of the LSA, the BCF was not recorded.

The credit facility included affirmative and negative covenants. The affirmative covenants include, among others, covenants requiring the Company to maintain its legal existence and governmental approvals deliver certain financial reports and maintain insurance coverage. The negative covenants included, among others, restrictions on transferring collateral, incurring additional indebtedness, engaging in mergers or acquisitions, paying dividends or making other distributions, making investments, creating liens, selling assets, and undergoing a change in control, in each case subject to certain exceptions. In general, the Term Loan prohibits the Company from (i) repurchasing or redeeming any class of capital stock, including common stock or (ii) declaring or paying any cash dividend or making cash distribution on any class of capital stock, including common stock.

The LSA included provisions requiring the embedded interest rate reset upon an event of default and the put option upon an event of default or qualified change of control each represent an embedded derivative instrument requiring bifurcation from the loan. The embedded derivatives were bundled and valued as one compound derivative in accordance with the applicable accounting guidance

for derivatives and hedging. The fair value of the compound derivative at issuance of $11 was recorded as a derivative liability and as a discount to the debt. The derivative liability is remeasured at fair value at each reporting date, with changes in fair value being recorded as other income (expense) in the statements of operations (Note 10). At June 30, 2018 and December 31, 2017, the fair value of the derivative liability was valued at $0 and $1, respectively. The net debt discounts resulting from the embedded compound derivative and lender fees have been amortized as interest expense from the date of issuance through the maturity date using the effective interest method. The Company incurred interest expense of $80 and $186 during the three and six months ended June 30, 2018 and $172 and $359 during the three and six months ended June 30, 2017, respectively. Of the total interest expense, $57 and $131 was payable in cash during the three and six months ended June 30, 2018 and $126 and $265 was payable in cash during the three and six months ended June 30, 2017, respectively.

The carrying amounts of the Company’s Term Loan as of June 30, 2018 and December 31, 2017 were as follows:

Public Offering

On April 3, 2018, the Company closed its firm commitment underwritten public offering in which, pursuant to the underwriting agreement (the “Underwriting Agreement”) entered into between the Company and Oppenheimer & Co. Inc., as representative of the underwriters (the “Underwriters”), dated March 28, 2018, the Company issued and sold (i) 15,660,000 common units (“Common Units”), with each Common Unit being comprised of one share of the Company’s common stock, par value $0.0001 per share, one Series A warrant (collectively, the “Series A Warrants”) to purchase one share of common stock and one Series B warrant (collectively, the “Series B Warrants”) to purchase one share of common stock, and (ii) 7,840,000 pre-funded units (the “Pre-Funded Units” and, together with the Common Units, the “Units”), with each Pre-Funded Unit being comprised of one pre-funded warrant to purchase one share of common stock, one Series A Warrant and one Series B Warrant. The public offering price was $0.65 per Common Unit and $0.64 per Pre-Funded Unit, and the gross proceeds received by the Company on April 3, 2018 pursuant to such sales were $15,197, prior to deducting underwriting discounts and commissions and other estimated offering expenses.

In addition, on April 4, 2018, the Company closed on the sale of 1,150,000 additional Common Units pursuant to the Underwriters’ option to purchase up to an additional 1,150,000 Units, which were exercised in full. After giving effect to the exercise of the Underwriters’ overallotment option, the gross aggregate proceeds from the offering on April 3 and 4 were $15,944, prior to deducting underwriting discounts and commissions and other estimated offering expenses.

All of the pre-funded warrants issued in the offering were exercised in April 2018 and, as 150,000 were exercised on a cashless basis, resulted in the issuance of an additional 7,837,061 shares of common stock with gross proceeds of $78.

The Series A Warrants included in the Common Units and the Pre-Funded Units were immediately exercisable at a price of $0.65 per share of common stock, subject to adjustment in certain circumstances, and will expire six months from the date of issuance. The Series B Warrants included in the Common Units and the Pre-Funded Units were immediately exercisable at a price of $0.75 per share of common stock, subject to adjustment in certain circumstances, and will expire five years from the date of issuance. The shares of common stock, or Pre-Funded Warrants in the case of the Pre-Funded Units, and the Series A Warrants and Series B Warrants were offered together, but the securities contained in the Common Units and the Pre-Funded Units were issued separately.

The Company agreed to pay Oppenheimer a commission of (a) 7% of the gross proceeds raised up to $5,000 and (b) 6.5% of the gross proceeds raised in excess of $5,000. The Company also agreed to pay or reimburse certain expenses on behalf of Oppenheimer. A total of $1,497 of commissions and other issuance costs were associated with the public offering.

The net proceeds to the Company from the Offering were approximately $14,525, after deducting the underwriting discounts and commissions and estimated offering expenses payable by the Company. The Company intends to use the net proceeds from the Offering for research and development of its therapeutic candidates, particularly the development of Pulmazole, as well as for working capital and general corporate purposes.

At-the-Market Offering

On March 17, 2017, the Company entered into an At-The-Market Sales Agreement (the “Sales Agreement”) with BTIG, LLC (“BTIG”) to act as the Company’s sales agent with respect to the issuance and sale of up to $11,000,000 of the Company’s shares of common stock, from time to time in an at-the-market public offering (the “Offering”). Sales of common stock under the Sales Agreement are made pursuant to an effective shelf registration statement on Form S-3, which was filed with the Securities and Exchange Commission on July 15, 2016, and subsequently declared effective on August 3, 2016 (File No. 333-212546), and a related prospectus. BTIG acts as the Company’s sales agent on a commercially reasonable efforts basis, consistent with its normal trading and sales practices and applicable state and federal laws, rules and regulations and the rules of The NASDAQ Global Market. If expressly authorized by the Company, BTIG may also sell the Company’s common stock in privately negotiated transactions. There is no specific date on which the Offering will end, there are no minimum sale requirements and there are no arrangements to place any of the proceeds of this offering in an escrow, trust or similar account.

BTIG is entitled to compensation at a fixed commission rate of 3.0% of the gross proceeds from the sale of the Company’s common stock pursuant to the Sales Agreement.

During the six-month period ended June 30, 2018, the Company sold 1,232,662 shares of its common stock under the Sales Agreement at an average selling price of approximately $1.54 per share which resulted in gross proceeds of approximately $1,904 and net proceeds of approximately $1,847 after payment of 3% commission to BTIG and other issuance costs.

9. Stock-Based Compensation

The Company sponsors the Pulmatrix, Inc. 2013 Employee, Director and Consultant Equity Incentive Plan (the “2013 Plan). As of June 30, 2018, the 2013 Plan provides for the grant of up to 12,500,000 shares of common stock, of which 2,060,067 shares remained available for future grant.

In addition, the Company has two legacy plans: The Pulmatrix Operating’s 2013 Employee, Director and Consultant Equity Incentive Plan (the “Original 2013 Plan”) and Pulmatrix Operating’s 2003 Employee, Director, and Consultant Stock Plan (the “2003 Plan”). As of June 30, 2018, a total of 498,882 shares of common stock may be delivered under options outstanding under the Original 2013 Plan and the 2003 Plan, however no additional awards may be granted under the Original 2013 Plan or the 2003 Plan.

Options

During the six months ended June 30, 2018, the Company granted 5,932,000 options to employees and 775,000 options to directors. At the date of grant, the fair value of the options was $1,884 and $248 respectively. No options were granted to consultants during the period. The stock options granted vest over either 36 or 48 months (the “Time Based Options”). Subject to the grantees’ continuous service with the Company and as defined in the grant agreement, Time Based Options vest in one of the following ways: (i) 25% on the first anniversary of the option grant date and the remainder in 36 equal monthly installments beginning in the month after the vesting start date, (ii) 25% on the option grant date and the remainder in 36 equal monthly installments beginning in the month after the vesting start date or (iii) in 48 equal monthly installments beginning on the monthly anniversary of the vesting start date. Stock options generally expire ten years after the date of grant.

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

Table of Contents

The estimated fair values of employee stock options granted during the three and six months ended June 30, 2018 and 2017, were determined on the date of grant using the Black-Scholes option-pricing model with the following assumptions:

The risk-free interest rate was obtained from U.S. Treasury rates for the applicable periods. The Company’s expected volatility was based upon the historical volatility for industry peers and used an average of those volatilities. The expected life of the Company’s options was determined using the simplified method as a result of limited historical data regarding the Company’s activity. The dividend yield considers that the Company has not historically paid dividends and does not expect to pay dividends in the foreseeable future. As of June 30, 2018, there was $4,849 of unrecognized stock-based compensation expense related to unvested stock options granted under the Company’s stock award plans. This expense is expected to be recognized over a weighted-average period of approximately 2.2 years.

The following table presents total stock-based compensation expense for the three and six months ended June 30, 2018 and 2017:

Restricted Stock Units (RSU)

In August 2015, the Company granted 10,374 RSUs to other employees that vested over a two year period. The Company recorded no stock-based compensation expense for the RSUs during the three and six months ended June 30, 2018 and $6 and $13 for the RSUs during the three and six months ended June 30, 2017, respectively. At June 30, 2018, no RSUs were outstanding.

10. Fair Value Measurements

Information about the liabilities measured at fair value on a recurring basis as of June 30, 2018 and December 31, 2017, and the input categories associated with those liabilities, is as follows:

Embedded Compound Derivatives — LSA with Hercules

As described in Note 5, the LSA contained an interest rate reset upon an event of default and a put option upon an event of default or qualified change of control. Each of these features represents an embedded derivative instrument requiring bifurcation from the Term Loan. The embedded derivatives were bundled and valued as one compound derivative in accordance with the applicable accounting guidance for derivatives and hedging. The proceeds from the issuance of the Term Loan were allocated first to the warrant and

Table of Contents

compound derivative at their respective fair values, with the residual going to the carrying amount of the loan resulting in a discount to the face value of the debt. The fair value of the compound derivative upon issuance of $11 was recognized as a derivative liability and was adjusted to fair value at each reporting date. The loan was repaid in its entirety according to its terms and as of June 30, 2018, the derivative liability had a fair value of zero.

A roll-forward of the preferred stock warrant liability and derivative liability categorized with Level 3 inputs is as follows:

Gains and/or losses arising from changes in the estimated fair value of the warrants and embedded compound derivatives were recorded within other income, net, on the condensed consolidated statement of operations.

11. Net Loss Per Share

The Company computes basic and diluted net loss per share using a methodology that gives effect to the impact of outstanding participating securities (the “two-class method”). As the three months and six months ended June 30, 2018 and 2017 resulted in net losses attributable to common shareholders, there is no income allocation required under the two-class method or dilution attributed to weighted average shares outstanding in the calculation of diluted net loss per share.

The following potentially dilutive securities outstanding prior to the use of the treasury stock method have been excluded from the computation of diluted weighted-average shares outstanding, as they would be anti-dilutive.

12. Commitments

Future minimum lease payments under the non-cancelable operating lease for office and lab space is as follows:

The Company’s proprietary dry powder delivery platform, iSPERSE™ (inhaled Small Particles Easily Respirable and Emitted), is engineered to deliver small, dense particles with highly efficient dispersibility and delivery to the airways, which can be used with an array of dry powder inhaler technologies and can be formulated with a variety of drug substances. The Company is developing a pipeline of iSPERSE-based therapeutic candidates targeted at prevention and treatment of a range of respiratory diseases and infections with significant unmet medical needs. Since our inception in 2003, we have devoted substantially all of our efforts to product research and development. We do not have any products approved for sale and have not generated any revenue from product sales. We have funded our operations to date through proceeds from issuances of common and convertible preferred stock, issuances of convertible debt, collaborations with third parties and non-dilutive grants received from government agencies.

In our underwritten public offering that closed in April 2018 (“the Offering”), the Company issued and sold (i) 16,810,000 common units (“Common Units”), with each Common Unit being comprised of one share of the Company’s common stock, par value $0.0001 per share, one Series A warrant (collectively, the “Series A Warrants”) to purchase one share of common stock and one Series B warrant (collectively, the “Series B Warrants”) to purchase one share of common stock, and (ii) 7,840,000 pre-funded units (the “Pre-Funded Units” and, together with the Common Units, the “Units”), with each Pre-Funded Unit being comprised of one pre-funded warrant to purchase one share of common stock, one Series A Warrant and one Series B Warrant. Gross proceeds of the public offering before commissions and fees were approximately $15.9 million. All of the pre-funded warrants issued in the Offering were exercised in April 2018 and, as 150,000 were exercised on a cashless basis, resulted in the issuance of an additional 7,837,061 shares of common stock and gross proceeds of approximately $0.1 million. Aggregate gross proceeds for the public offering in April 2018 were approximately $16.0 million.

We expect to continue to incur significant expenses and increasing operating losses for at least the next several years based on our drug development plans. We expect our expenses and capital requirements will increase substantially in connection with our ongoing activities, as we:

We will not generate product sales unless and until we successfully complete clinical developments and obtain regulatory approvals for our product candidates. Additionally, we currently utilize third-party contract research organizations, or CROs, to carry out our clinical development activities, and we do not yet have a commercial organization. If we obtain regulatory approval for any of our product candidates, we expect to incur significant expenses related to developing our internal commercialization capability to support product sales, marketing and distribution. Accordingly, we anticipate that we will seek to fund our operations through public or private equity or debt financings or other sources, potentially including collaborative commercial arrangements. Likewise, we intend to seek to limit our commercialization costs by partnering with other companies with complementary capabilities or larger infrastructure including sales and marketing.

Because of the numerous risks and uncertainties associated with product development, we are unable to predict the timing or amount of increased expenses or when or if we will be able to achieve or maintain profitability. Even if we are able to generate product sales, we may not become profitable. If we fail to become profitable or are unable to sustain profitability on a continuing basis, then we may be unable to continue our operations at planned levels and be forced to reduce or terminate our operations.

Financial Overview

Revenues

To date, we have not generated any product sales. Our 2018 revenue resulted from an award from Cystic Fibrosis Foundation Therapeutics (“CFFT”), the nonprofit drug discovery and development affiliate of the Cystic Fibrosis Foundation, to support the development of Pulmazole for the treatment of ABPA in patients with asthma and cystic fibrosis.

Research and Development Expenses

Research and development expenses consist primarily of costs incurred for the research and development of our preclinical and clinical candidates, and include:

We expense research and development costs to operations as incurred. We recognize costs for certain development activities, such as clinical trials, based on an evaluation of the progress to completion of specific tasks using data such as patient enrollment, clinical site activations or information provided to us by our vendors.

15

Table of Contents

Research and development activities are central to our business model. We utilize a combination of internal and external efforts to advance product development from early stage work to clinical trial manufacturing and clinical trial support. External efforts include work with consultants and substantial work at CROs and CMOs. We support an internal research and development team and facility for our pipeline programs. To move these programs forward along our development timelines, a large portion, approximately

69% of staff, are research and development employees. In addition, we maintain a 12,000 square foot research and development facility which includes capital equipment for the manufacture and characterization of our iSPERSE™ powders for our pipeline programs. As we identify opportunities for iSPERSE™ in respiratory indications, we anticipate additional head count, capital, and development costs will be incurred to support these programs.

Because of the numerous risks and uncertainties associated with product development, however, we cannot determine with certainty the duration and completion costs of these or other current or future preclinical studies and clinical trials. The duration, costs and timing of clinical trials and development of our product candidates will depend on a variety of factors, including the uncertainties of future clinical and preclinical studies, uncertainties in clinical trial enrollment rates and significant and changing government regulation. In addition, the probability of success for each product candidate will depend on numerous factors, including competition, manufacturing capability and commercial viability.

General and Administrative Expenses

General and administrative expenses consist principally of salaries and related costs such as stock-based compensation for personnel and consultants in executive, finance, business development, corporate communications and human resource functions, facility costs not otherwise included in research and development expenses, patent filing fees and professional legal fees. Other general and administrative expenses include travel expenses and professional fees for consulting, auditing and tax services.

We anticipate that our general and administrative expenses will increase in the future as we increase our headcount to support our continued research and development and potential commercialization of our product candidates. We also anticipate increased expenses related to audit, legal, regulatory, and tax-related services associated with maintaining compliance with exchange listing and Securities and Exchange Commission requirements, director and officer liability insurance, investor relations costs and other costs associated with being a public company. Additionally, if and when we believe a regulatory approval of a product candidate appears likely, we anticipate an increase in staffing and related expenses as a result of our preparation for commercial operations, especially as it relates to the sales and marketing of our product candidates.

Interest Expense

We have been incurring interest expense associated with a term loan executed in June 2015. The term loan was paid in its entirety as of June 30, 2018.

Other Income, Net

Other income, net is comprised primarily of interest income on cash deposits and gains and/or losses resulting from fair value adjustments for compound derivative instruments embedded within certain of our convertible notes.

Critical Accounting Policies

This management’s discussion and analysis of our financial condition and results of operations is based on our financial statements, which have been prepared in accordance with U.S. generally accepted accounting principles. The preparation of these financial statements requires us to make estimates and judgments that affect the reported amounts of assets, liabilities, and expenses and the disclosure of contingent assets and liabilities in our financial statements. On an ongoing basis, we evaluate our estimates and judgments, including those related to accrued expenses and stock-based compensation. We base our estimates on historical experience, known trends and events, and various other factors that are believed to be reasonable 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.

While our significant accounting policies are described in more detail in the notes to our condensed consolidated financial statements appearing elsewhere in this Form 10-Q and in our audited financial statements included in our annual report on Form 10-K filed with the SEC on March 13, 2018, we believe the following accounting policies to be most critical to the judgments and estimates used in the preparation of our financial statements.

16

Table of Contents

Use of Estimates

In preparing financial statements in conformity with GAAP, management is required to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements, as well as the reported amounts of expenses during the reporting period. Due to inherent uncertainty involved in making estimates, actual results may differ from these estimates. On an ongoing basis, the Company evaluates its estimates and assumptions. These estimates and assumptions include valuing equity securities in share-based payments, estimating fair value of equity instruments recorded as derivative liabilities, estimating the useful lives of depreciable and amortizable assets, valuation allowance against deferred tax assets, goodwill impairment, and estimating the fair value of long-lived assets to assess whether impairment charges may apply.

Revenue Recognition

Our principal sources of revenue are income from reimbursement of clinical study costs. During the six months ended June 30, 2018, our principal source of revenue was income for reimbursement of clinical study costs as part of a grant received from CFFT. In all instances, revenue is recognized only when the price is fixed or determinable, persuasive evidence of an arrangement exits, delivery has occurred or services have been rendered, and collectability of the resulting receivable is reasonably assured.

Goodwill

Goodwill represents the difference between the consideration transferred and the fair value of the net assets acquired under the acquisition method of accounting for push-down accounting. Goodwill is not amortized but is evaluated for impairment on an annual basis, during the fourth quarter, or more frequently if an event occurs or circumstances change that would more likely than not reduce the fair value of the related reporting unit below its carrying amount. When performing the impairment assessment, the accounting standard for testing goodwill for impairment permits a company to first assess the qualitative factors to determine whether the existence of events and circumstances indicates that it is more likely than not that the goodwill is impaired. If we believe, as a result of the qualitative assessment, that it is more likely than not that the fair value of goodwill is impaired, we must perform the goodwill impairment test. We have determined that goodwill was not impaired as of June 30, 2018.

Results of Operations

Three Months Ended June 30, 2018 Compared with Three Months Ended June 30, 2017

The following table sets forth our results of operations for each of the periods set forth below (in thousands):

Research and development expenses — For the three months ended June 30, 2018, research and development expense was $4.0 million compared to $3.3 million for the three months ended June 30, 2017, an increase of $0.7 million. The increase was primarily due to increased spend of $0.6 million on the Pulmazole project and $0.3 million in employment costs, partially offset by a decreased spend $0.2 million on the PUR1800 project.

General and administrative expenses — For the three months ended both June 30, 2018 and June 30, 2017, general and administrative expense was $2.1 million.

Interest expense — For the three months ended June 30, 2018 interest expense was $0.1 million compared to $0.2 million for the three months ended June 30, 2017. During both periods, interest expense incurred related to the term loan agreement that we entered in June 2015.

Six Months Ended June 30, 2018 Compared with Six Months Ended June 30, 2017

The following table sets forth our results of operations for each of the periods set forth below (in thousands):

Revenue — For the six months ended June 30, 2018, revenue was $0.2 million compared to no revenue for the six months ended June 30, 2017. The increase in revenue was the result of clinical study costs reimbursed by CFFT.

Research and development expenses — For the six months ended June 30, 2018, research and development expense was $7.2 million compared to $5.0 million for the six months ended June 30, 2017, an increase of $2.2 million. The increase was primarily due to increased spend of $1.4 million on the Pulmazole project, $0.3 million on the PUR1800 project, and $0.5 million in employment costs.

General and administrative expenses — For the six months ended June 30, 2018, general and administrative expense was $4.2 million compared to $3.7 million for the six months ended June 30, 2017, an increase of $0.5 million. The increase was primarily due to an increase of $0.4 in employment costs and $0.4 million in patent costs, partially offset by a decrease of $0.3 million in legal and professional consulting costs.

Interest expense — For the six months ended June 30, 2018 interest expense was $0.2 million compared to $0.4 million for the six months ended June 30, 2017. During both periods, interest expense incurred related to the term loan agreement that we entered in June 2015.

Liquidity and Capital Resources

Through June 30, 2018, we have incurred an accumulated deficit of $185.4 million, primarily as a result of expenses incurred through a combination of research and development activities related to our various product candidates and general and administrative expenses supporting research and development and business activities. We have financed our operations since inception primarily through the sale of preferred and common stock and the issuance of convertible promissory notes and term loans. Our total cash and cash equivalents balance as of June 30, 2018 was $8.3 million. In April 2018, the Company received gross proceeds of approximately $15.9 million in connection with the sale of the Units in the Offering. All of the pre-funded warrants issued in the Offering were exercised in April 2018 and, as 150,000 were exercised on a cashless basis, resulted in the issuance of an additional 7,837,061 shares of common stock and gross proceeds of approximately $0.1 million.

To continue our operations, we will need to raise additional capital by the end of 2018. We anticipate that we will continue to incur losses, and that such losses will increase over the next several years due to development costs associated with our iSPERSE™ pipeline programs. We expect that our research and development and general and administrative expenses will continue to increase and, as a result, we will need additional capital to fund our operations, which we may raise through a combination of equity offerings, debt financings, other third-party funding and other collaborations and strategic alliances. The Company’s ability to continue as a going concern is dependent upon its ability to obtain additional equity or debt financing and, ultimately, to generate revenue. Those factors raise substantial doubt about the Company’s ability to continue as a going concern within one year from the date of filing these condensed consolidated financial statements.

Table of Contents

The following table sets forth the major sources and uses of cash for each of the periods set forth below (in thousands):

Cash Flows from Operating Activities

Net cash used in operating activities for the six months ended June 30, 2018 was $8.1 million, which was primarily the result of a net loss of $11.4 million, partially offset by $1.9 million of net non-cash adjustments and $1.4 million in cash inflows associated with changes in operating assets and liabilities. Our non-cash adjustments were primarily comprised of $1.7 million of stock-based compensation expense, $0.1 million of depreciation and amortization, and $0.1 million of debt issuance expense. The net cash inflows associated with changes in operating assets and liabilities was primarily due to increases in accounts payable of $1.0 million, increases in accrued expenses of $0.3 million, and increases in prepaid expenses and other current assets of $0.1 million.

Net cash used in operating activities for the six months ended June 30, 2017 was $6.6 million, which was primarily the result of a net loss of $9.1 million, partially offset by $1.6 million of net non-cash adjustments and $0.9 million in cash inflows associated with changes in operating assets and liabilities. Our non-cash adjustments were primarily comprised of $1.3 million of stock-based compensation expense, $0.1 million of depreciation and amortization, and $0.1 million of non-cash interest expense. The net cash inflows associated with changes in operating assets and liabilities was primarily due to an increase in accrued expenses of $1.2 million, partially offset by an increase in prepaid expenses and other current assets of $0.2 million and a decrease in accounts payable of $0.2 million.

Cash Flows from Investing Activities

Net cash used in investing activities for the six months ended June 30, 2018 and June 30, 2017 were entirely due to purchases of property and equipment.

Cash Flows from Financing Activities

Net cash provided by financing activities for the six months ended June 30, 2018 was $12.9 million, as compared to $13.5 for the six months ended June 30, 2017. Net cash provided by financing activities for the six months ended June 30, 2018 resulted from the issuance of common stock, net of issuance costs of $16.4 million, partially offset by $3.5 million of principal and end of term loan payments. Net cash provided by financing activities for the six months ended June 30, 2017 resulted from the issuance of common stock of $14.5 million and $0.3 million from the exercise of stock options, partially offset by $1.3 million of term loan principal payments.

Financings

On March 17, 2017, the Company entered into an At-The-Market Sales Agreement with respect to the issuance and sale of up to $11 million of the Company’s common stock from time to time in an at-the-market public offering. During the six months ended June 30, 2018, the Company sold 1,232,622 shares of its common stock pursuant to the At-The-Market Sales Agreement for aggregate net proceeds of $1.8 million.

On March 28, 2018, we entered into an underwriting agreement with Oppenheimer and Co., Inc. relating to the Offering, pursuant to which the Company sold, 16,810,000 Common Units and 7,840,000 Pre-Funded Units. All of the pre-funded warrants issued in the Offering were exercised in April 2018 and, as 150,000 were exercised on a cashless basis, resulted in the issuance of an additional 7,837,061 shares of common stock. Each Common Unit was comprised of one share of common stock, one Series A Warrant to purchase one share of common stock and one Series B Warrant to purchase one share of common stock. Each Pre-Funded Unit was comprised of one pre-funded warrant to purchase one share of common stock, one Series A Warrant and one Series B Warrant. Gross proceeds from the Offering and of the exercise of the pre-funded warrants issued in the Offering, before commissions and fees, were approximately $16.0 million.

Table of Contents

Based on our planned use for our existing cash resources, we believe that our available funds will be sufficient to enable us to support clinical development of our Pulmazole program through the issuance of the final report on the Phase Ib trial, preparation costs relating to our planned Phase II trial and completion of a toxicology study in support of PUR1800, the latter of which is expected to conclude during the fourth quarter, 2018. The funding will not be sufficient to complete additional clinical work for any of the pipeline programs. We have based our projections of operating capital requirements on assumptions that may prove to be incorrect and we may use all of our available capital resources sooner than we expect. Because of the numerous risks and uncertainties associated with research, development and commercialization of pharmaceutical products, we are unable to estimate the exact amount of our operating capital requirements. Our future funding requirements will depend on many factors, including, but not limited to:

If we cannot expand our operations or otherwise capitalize on our business opportunities because we lack sufficient capital, our business, financial condition and results of operations could be materially adversely affected.

Off-Balance Sheet Arrangements

We have no off-balance sheet arrangements that have or are reasonably likely to have a current or future effect on our financial condition, changes in financial condition, revenues or expenses, results of operations, liquidity, capital expenditures or capital resources that is material to investors.

Not applicable.

(a) Evaluation of Disclosure Controls and Procedures. Our principal executive officer and principal financial officer, after evaluating the effectiveness of our disclosure controls and procedures (as defined in Rules 13a-15(e) and 15d-15(e)) promulgated under the Securities Exchange Act of 1934, as amended (the “Exchange Act”)) as of the end of the period covered by this Form 10-Q, have concluded that, based on such evaluation, our disclosure controls and procedures were effective to ensure that information required to be disclosed by us in the reports that we file or submit under the Exchange Act is recorded, processed, summarized and reported, within the time periods specified in the SEC’s rules and forms, and is accumulated and communicated to our management, including our principal executive and principal financial officers, or persons performing similar functions, as appropriate to allow timely decisions regarding required disclosure.

In designing and evaluating our disclosure controls and procedures, our management recognizes that any controls and procedures, no matter how well designed and operated, can provide only reasonable assurance of achieving the desired control objectives, and our management necessarily is required to apply its judgment in evaluating the cost-benefit relationship of possible controls and procedures.

(b) Changes in Internal Controls. There were no changes in our internal control over financial reporting, identified in connection with the evaluation of such internal control that occurred during the quarter ended June 30, 2018 that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

PART II — OTHER INFORMATION

From time to time, we may be involved in litigation that arises through the normal course of business. As of the date of this filing, we are not aware of any material legal proceedings to which we or any of our subsidiaries is a party or to which any of our property is subject, nor are we aware of any such threatened or pending litigation or any such proceedings known to be contemplated by governmental authorities.

20

Table of Contents

We are not aware of any material proceedings in which any of our directors, officers or affiliates or any registered or beneficial stockholder of more than 5% of our common stock, or any associate of any of the foregoing, is a party adverse to or has a material interest adverse to, us or any of our subsidiaries.

There have been no material changes to the risk factors disclosed under “Item 1A. Risk Factors” of our most recent Annual Report on Form 10-K, except as set forth below. For more information concerning our risk factors, please refer to “Item 1A. Risk Factors” of our most recent Annual Report on Form 10-K.

We will need to raise additional capital to meet our business requirements in the future and such capital raising may be costly or difficult to obtain and could dilute our stockholders’ ownership interests.

Our current capital will only be sufficient to enable us to continue operations for a short period of time. In order to fully realize all of our business objectives, absent any non-dilutive funding from a strategic partner or some other strategic transactions, we will need to raise additional capital before the end of 2018, which additional capital may not be available on reasonable terms or at all. For instance, we will need to raise additional funds to accomplish the following:

Any additional capital raised through the sale of equity or equity backed securities will dilute our stockholders’ ownership percentages and could also result in a decrease in the market value of our equity securities.

The terms of any securities issued by us in future financing transactions may be more favorable to new investors, and may include preferences, superior voting rights and the issuance of warrants or other derivative securities, which may have a further dilutive effect on the holders of any of our securities then outstanding.

Furthermore, any additional capital financing that we may need in the future may not be available on terms favorable to us, or at all. If we are unable to obtain such additional financing on a timely basis, we may have to curtail our development activities and growth plans and/or be forced to sell assets, perhaps on unfavorable terms, which would have a material adverse effect on our business, financial condition and results of operations, and ultimately could be forced to discontinue our operations and liquidate, in which event it is unlikely that stockholders would receive any distribution on their shares. Further, we may not be able to continue operating if we do not generate sufficient revenues from operations needed to stay in business.

In addition, we may incur substantial costs in pursuing future capital financing, including investment banking fees, legal fees, accounting fees, securities law compliance fees, printing and distribution expenses and other costs. We may also be required to recognize non-cash expenses in connection with certain securities we issue, such as convertible notes and warrants, which may adversely impact our financial condition and cause further dilution to our stockholders.

We will be required to raise additional capital to fund our operations, and we may not be able to continue as a going concern if we are unable to do so.

Pharmaceutical product development, which includes research and development, pre-clinical and clinical studies and human clinical trials, is a time-consuming and expensive process that takes years to complete. We anticipate that our expenses will increase substantially as we advance Pulmazole into Phase II trials and pursue development of PUR1800 or other iSPERSE-based product candidates and/or pursue development of iSPERSE-based pharmaceuticals in additional indications. Based upon our current expectations, we believe that our existing capital resources will enable us to continue planned operations through the fourth quarter of 2018. We cannot assure you, however, that our plans will not change or that changed circumstances will not result in the depletion of our capital resources more rapidly than we currently anticipate. We will need to raise additional funds, whether through the sale of equity or debt securities, the entry into strategic business collaborations, the establishment of other funding facilities, licensing arrangements, or asset sales or other means, in order to continue our research and development and clinical trial programs for our iSPERSE-based product candidates and to support our other ongoing activities. However, it may be difficult for us to raise additional funds through these planned measures if we are able to at all. Since inception, we have incurred losses each year and have an accumulated deficit of $185.4 million, which may raise concerns about our solvency and affect our ability to raise additional capital.

21

Table of Contents

The amount of additional funds we need will depend on a number of factors, including:

We have raised capital in the past primarily through debt and private placements of stock. We may in the future pursue the sale of additional equity and/or debt securities, or the establishment of other funding facilities including asset based borrowings. There can be no assurances, however, that we will be able to raise additional capital through such an offering on acceptable terms, or at all. Issuances of additional debt or equity securities could impact the rights of the holders of Company Common Stock and may dilute their ownership percentage. Moreover, the establishment of other funding facilities may impose restrictions on our operations. These restrictions could include limitations on additional borrowing and specific restrictions on the use of our assets, as well as prohibitions on our ability to create liens, pay dividends, redeem our stock or make investments. We also may seek to raise additional capital by pursuing opportunities for the licensing or sale of certain intellectual property and other assets. We cannot offer assurances, however, that any strategic collaborations, sales of securities or sales or licenses of assets will be available to us on a timely basis or on acceptable terms, if at all.

In the event that sufficient additional funds are not obtained through strategic collaboration opportunities, sales of securities, funding facilities, licensing arrangements and/or asset sales on a timely basis, we will be required to reduce expenses through the delay, reduction or curtailment of our projects, including Pulmazole or PUR1800 development activities, or reduction of costs for facilities and administration. Moreover, if we do not obtain such additional funds, there will be continued doubt about our ability to continue as a going concern and increased risk of insolvency and loss of investment to the holders of our securities. If we are or become insolvent, investors in our stock may lose the entire value of their investment.

(a) Unregistered Sales of Equity Securities

None.

(b) Issuer Purchases of Equity Securities

We did not repurchase any of our equity securities during the quarter ended June 30, 2018.
