Exhibit 99.1

Pulmatrix Announces Peer-Reviewed Publication of Clinical Results for its Orally Inhaled DHE for Acute Migraine (PUR3100)

OrallyInhaled PUR3100 is associated with rapid systemic PK within the therapeutic window and a mean time to Cmax matching intravenously (IV)administered DHE.

Self-administeredPUR3100 showed improved safety and tolerability relative to IV DHE.

Pulmatrixpreviously received FDA’s acceptance of an IND application and a “study may proceed” letter for a Phase 2 study, positioningPUR3100 as Phase 2-ready.

Bedford, Mass., May 15, 2024 – Pulmatrix, Inc. (“Pulmatrix” or the “Company”) (Nasdaq: PULM), a clinical-stage biopharmaceutical company developing innovative inhaled therapies to address serious central nervous system and pulmonary diseases using its patented dry powder inhalation iSPERSE™ technology, today announced publication of, “Safety, tolerability, and pharmacokinetics of a single orally inhaled dose of PUR3100, a dry powder formulation of dihydroergotamine versus intravenous dihydroergotamine: A Phase 1 randomized, double-blind study in healthy adults” in the peer-reviewed publication Headache: The Journal of Head and Face Pain.

Ted Raad, Chief Executive Officer of Pulmatrix, commented, “In this trial, PUR3100 demonstrated the potential for rapid pain relief and improved DHE tolerability versus IV DHE. With a Tmax of 5 minutes and a Cmax in the therapeutic window for all doses tested, we believe that PUR3100 has the potential to address an unmet need for acute migraine sufferers and we are pursuing different options to advance PUR3100 into a Phase 2 clinical trial to further investigate its promising profile in treating acute migraine.”

The completed Phase 1 study demonstrated optimal pharmacokinetics and improved tolerability of PUR3100 compared to IV DHE. The Phase 1 trial was a randomized, double-dummy, double-blinded design to assesses the safety, tolerability, and pharmacokinetics (PK) of three dose groups treated with inhaled PUR3100 with intravenous (IV) placebo, compared to a single dose of IV DHE (DHE mesylate injection) with inhaled placebo in healthy volunteers. All doses of PUR3100 were generally well tolerated with a lower incidence of nausea (21% vs. 86%), vomiting (0% vs. 29%), and headache (16% vs. 57%) compared to IV DHE. The PK profile of PUR3100 versus IV DHE was characterized by a similar mean time to Cmax (5 vs. 5.5 min), with reduced AUC0–2h (1120–4320 vs. 6340), and a lower Cmax (3620–14,400 vs. 45,000). All doses of PUR3100 were associated with mean Cmax above the minimum level required to achieve efficacy (1000 pg/mL).

Please use this link to the early view on the journal, Headache: https://doi.org/10.1111/head.14731

Pulmatrix is currently looking at opportunities to finance or partner PUR 3100 to initiate a potential Phase 2 clinical study.
