2021 and Recent Program and Corporate Highlights

Pulmazole

• On January 27, 2021, the Company conducted a Type-C meeting with FDA to finalize its plans to commence a Phase 2b study with topline data on registrational endpoints in allergic bronchopulmonary aspergillosis (ABPA). If successful, these data may enable a Phase 3 registration study.
• On November 9, 2021, the Company announced the positive resolution of a contractual dispute with Cipla, thereby allowing Pulmatrix and Cipla to progress together toward the Phase 2b study in ABPA that aims to provide data on potential registrational endpoints in ABPA. Pulmatrix expects to initiate patient dosing for the Phase 2b study in Q1 2023 and to deliver top-line data by mid-2024.

PUR3100

• On April 23, 2021, the company hosted a Key Opinion Leader event on PUR3100, an orally-inhaled dihydroergotamine (DHE) therapy. Migraine experts highlighted the potential benefits that PUR3100 (iSPERSE-enabled DHE) may provide to improve the standard of care and address the unmet needs of acute migraine sufferers.
• On January 25, 2022, the Company conducted a Type-C meeting with the FDA. This meeting along with pre-IND written responses has helped define the overall non-clinical and clinical program. The next trial will be a Phase 1 study in Australia allowing for generation of the most comprehensive dataset in a cost and time-efficient manner so as to have Phase 1 data in 2022. This study will form the basis for a US IND.
• The Phase 1 study is intended to assess not only safety, tolerability, and pharmacokinetics of PUR3100 in humans, but also provide preliminary comparative bioavailability data to support the use of the 505(b)(2) pathway for marketing authorization. The Company anticipates initiating patient dosing for the Phase 1 study in Australia in Q3 2022, with top-line data anticipated in Q4 2022. A Phase 2 study to determine efficacy will be conducted in migraine patients evaluating two doses that were selected based on the Phase 1 study results. This study is projected to commence dosing in Q2 2023 with data by year-end 2023.

PUR1800

• On August 18, 2021, the Company announced that results from 6-month and 9-month pre-clinical toxicology studies demonstrated no progression of 28-day findings, suggesting potential for chronic dosing of PUR1800 in indications beyond acute exacerbations of chronic obstructive pulmonary disease (AECOPD) including, but not limited to, steroid resistant asthma, chronic obstructive pulmonary disease (COPD) and idiopathic pulmonary fibrosis (IPF).
• On March 21, 2021, the company announced that PUR1800 achieved the primary endpoint of safety and tolerability in a Phase 1b clinical study with no serious adverse events observed. Preliminary pharmacokinetic and pharmacodynamic data are supportive of continued PUR1800 development in its primary therapeutic target of AECOPD as well other chronic inflammatory airway disease such as severe asthma, COPD and IPF. The Company plans to release more detailed results of the Phase 1b clinical study results at a relevant medical conference in the future.

Corporate Highlights

• On December 17, 2021, the Company announced the closing of a $6.75 million registered direct offering. Combined with $40 million raised in February 2021, the total funds raised in 2021 equaled $46.75 million in gross proceeds. The Company anticipates that its cash position is sufficient to fund operations into Q1 2024 and enable Pulmatrix to pursue clinical data milestones for PUR3100 Phase 1 and Phase 2 and Pulmazole Phase 2b trials.
• On February 28, the Company completed a reverse stock-split at a ratio of 1-for-20 (the "Reverse Split") which reduced the number of outstanding shares of the Company's common stock from approximately 65.9 million shares to 3.3 million shares. The number of authorized shares of the Company's common stock remains at 200,000,000.
• On March 1, the Company announced the hiring of Dr. Margaret Wasilewski as the Company's Chief Medical Officer. Dr. Wasilewski leverages over 25 years of experience in pharmaceutical drug development.
• On March 17, the Company announced that it regained compliance for its listing on Nasdaq, allowing continued access to capital markets and liquidity for its investors.

Fourth Quarter and Year-End Financial Results

Revenue was $5.2 million for the year ended December 31, 2021 as compared to $12.6 million for the year ended December 31, 2020, a decrease of $7.5 million. The decrease is related to $3.4 million fewer reimbursable pass-through expenses under our collaboration agreements and a $0.9 million decrease in license related revenues due to a pause in the development activities under the collaboration with Cipla during 2021, and a $3.2 million decrease in license related revenues under our prior collaboration agreement with Johnson & Johnson Enterprise Innovation.

Research and development expense was $15.4 million for the year ended December 31, 2021, as compared to $15.6 million for the year ended December 31, 2020, a decrease of $0.2 million. The decrease was primarily due to a decrease in spend of $2.5 million related to the Company's PUR1800 program as well as a decrease in spend of $1.7 million related to the Phase 2 Pulmazole clinical trial due to its COVID-19-related termination in 2020. This amount was then partially offset by increased spend of $3.2 million on pre-clinical and manufacturing costs related to our PUR3100 program, in addition to $0.8 million of operating costs in support of our overall clinical and pre-clinical programs.

General and administrative expense was $6.4 million for the year ended December 31, 2021, as compared to $6.9 million for the year ended December 31, 2020, a decrease of $0.5 million. The decrease was primarily due to decreased employment costs of $0.5 million.

Our total cash and cash equivalents balance as of December 31, 2021 was $53.8 million.
