Pulmatrix Reports 2016 Financial Results; Provides 2017 Outlook on Pulmonary Disease Pipeline

LEXINGTON, MA —Pulmatrix, Inc. (NASDAQ: PULM) today announces 2016 financial results, reviews the Company’s recent progress, and provides an outlook for 2017 for its pulmonary disease development pipeline.

“The Company continues to advance its twoiSPERSE-based product candidates and recently strengthened our balance sheet, with the closing of two registered direct offerings that brought in net proceeds of approximately $7.5 million,” saidRobert W. Clarke, Ph.D.,chief executive officer of Pulmatrix. “We expectpre-clinical data in the first half of 2017 on PUR1900 targeting fungal infections for severe asthma and cystic fibrosis patients and seek to secure a strategic partner(s) on PUR0200, a branded generic bronchodilator for COPD. As our product pipeline and iSPERSE technology continue to advance, we feel the Company is positioned for success as a leader in the treatment of Respiratory diseases.”

Planned 2017 Milestones

Pulmatrix plans to continue advancement of our active pipeline in 2017: Following on our 2016 successful clinical trial in the EU for PUR0200, a branded generic bronchodilator for COPD, the company is planning meetings with both EU and US Regulators regarding the critical path for clinical development to approval and plans to continue development towards initial clinical testing in patients of PUR1900, an inhaled anti-fungal initially targeted for patients with cystic fibrosis and severe asthma.

PUR0200

• Following up on our successful pharmacokinetic equivalence pilot trial in 2016, Pulmatrix plans to seek scientific advice from three EU countries to gain a better understanding of the pivotal trial design for PUR0200.

• Pulmatrix intends to seek apre-IND meeting with the FDA to inform the US clinical development path for PUR0200 in the second half of 2017.

• Continue CMC development work in the first half of 2017 to support a future European pivotal pharmacokinetic bioequivalence approval study as well as the US development path.

• Pulmatrix seeks to secure partnership for the rights to PUR0200 in 2017 for a geography or geographies to be determined.

PUR1900

• Complete CMC development work andnon-clinical safety testing to support clinical development of PUR1900 for severe asthma and cystic fibrosis.

• Plan a Phase I/IB trial in healthy normal volunteers (HNV) and severe asthma patients including safety/tolerability and pharmacokinetic readout following inhalation of PUR1900.

PUR1500

• Continuepre-clinical development of PUR1500 moving towards lead selection based on either a 505(b)2 or in license opportunity.

2016 and 2017 YTD Progress

In 2016 and early 2017, Pulmatrix achieved several research, clinical and business milestones, reflective of the Company’s progress. These milestones include the following:

• Completed the pilot study of PUR0200 for patients withchronic obstructive pulmonary disease (COPD) and announcedpositive pharmacokinetic bioavailability data that informed our continued development of PUR0200 forEuropean Registration.

• The U.S. Food and Drug Administration (FDA) grantedorphan drug designation to Pulmatrix’s wholly-owned drug candidate PUR1900. PUR1900 combines a previously approved anti-fungal drug with its proprietary dry powderiSPERSE^TM delivery platform to effectively deliver to the lungs a drug used to treat pulmonary fungal infections in patients with cystic fibrosis (CF).

• Announced the appointment of Dr. Matthew Sherman to the Board of Directors. Dr. Sherman is a board certified physician in medical oncology and internal medicine and has held various positions at Harvard Medical School. Dr. Sherman brings to Pulmatrix an extensive background and experience in drug development, clinical research, and regulatory affairs.

• Presentedpre-clinical data for PUR1900 at the North American Cystic Fibrosis Conference. The poster presentation compared the activity of PUR1900 against the oral reference drug and measured the deposition of the product in the lungs against systemic levels to demonstrate the products potential advantages in treating CF patients with fungal infections.

• Announced that its drug candidate for treating fungal infections in the lungs of CF patients, PUR1900, had been designated as a “Qualified Infectious Disease Product” (QIDP) by the U.S. Food & Drug Administration.

• Closed two registered direct offerings that brought in net proceeds of approximately $7.5 million.

• Released an animated life sciences video (ir.pulmatrix.com) to raise awareness of the problem of serious lung diseases—and to describe promising new treatments.

Financials

Pulmatrix ended 2016 with $4.2 million in cash and cash equivalents compared to $7.3 million as of September 30, 2016.

Revenue for 2016 was $0.8 million, compared to $1.2 million for 2015. The decrease was the result of the decreased revenue associated with the conclusion of the clinical study funded under our collaboration agreement to develop PUR0200 for COPD.

Research and development expense was $10.2 million for 2016, compared to $7.2 million for 2015, an increase of $3.0 million. The increase was primarily due to increases clinical development costs and external service costs on the PUR1900 project. General and administrative expense was $8.0 million for 2016, compared to $17.0 million for 2015, a decrease of $9.0 million. The decrease was primarily due to a reduction in employee stock-based compensation expense andnon-recurring merger related expenses that were incurred in 2015.

In 2016, the Company recorded awrite-off of intangibles, net of tax provision, of $4.5 million and a goodwill impairment of $5.0 million. Thesenon-cash charges did not have comparable charges in 2015 and related to assets that were recorded as part of the merger purchase accounting.

In 2015, the Company recorded a loss on the conversion of convertible notes, a fair value adjustment of preferred stock warrant liability, and a fair value adjustment of derivative liability. These items netted to a $2.1 millionnon-cash charge that did not reoccur in 2016.

Net loss for 2016 was $27.8 million compared to a net loss of $26.2 million in 2015. The increase in net loss was primarily attributable to net increase of $7.5 million innon-cash charges and an increase of $3.0 million in research and development expense, partially offset by a decrease of $9.0 million in general and administrative expense.
