Statements in this press release that are not purely historical are forward- looking statements. Such forward-looking statements include, among other things, references to novel technologies and methods and our business and product development plans, including the advancement of our proprietary and co-development programs into and through the clinic. Actual results could differ from those projected in any forward-looking statements due to numerous factors. Such factors include, among others, our ability to raise the additional funding we will need to continue to pursue our business and product development plans; the inherent uncertainties associated with developing new products or technologies and operating as a development stage company; our ability to develop, complete clinical trials for, obtain approvals for and commercialize any of our product candidates, including our ability to recruit and enroll patients in our studies; our ability to address the requests of the FDA; competition in the industry in which we operate and market conditions. These forward-looking statements are made as of the date of this press release, and we assume no obligation to update the forward-looking statements, or to update the reasons why actual results could differ from those projected in the forward-looking statements, except as required by law.

What are Anticalin proteins? A Novel Therapeutic Class with Underpinned by a Powerful Favorable Drug-Like Properties Target Drug Discovery Platform • Derived from lipocalins (human • Highly diverse libraries (>1011) of extracellular binding proteins) potential drug candidates… • TLC and NGAL lipocalins used as • Automated high-throughput drug “templates” for drug development screening technology (phage • Engineerable binding pocket for display)… robust target engagement • Extensive protein engineering • Monomeric, monovalent, small size know-how… (~18 kDa vs 150kDa mAbs) • …resulting in high hit rates, • Can be formulated for inhalable quick-to-development candidates delivery • Can be formatted into novel bi/multispecific constructs Anticalin • Broad IP position Protein 5

Anticalin Technology Advantages: Differentiated Respiratory Platform Tear lipocalin (TLC) is abundant in human lung and permeates lung epithelium Very low predicted immunogenicity Stable, monovalent molecules with high melting temperatures and insensitivity to mechanical stress Inhalation pharmacokinetics suitable for once or twice daily administration and compatible with flexible treatment regimes 8
PRS-060: IL-4Rα Antagonist Candidate PRS-060 Function/MoA Inhibiting IL4-Rα (disrupts IL‐4 & IL‐13 signaling) Indications Moderate-to-severe asthma Development Phase I multiple-ascending dose trial PRS-060 Co-development and U.S. co-commercialization Commercial Rights rights, including gross margin share 9
PRS-060 is an Inhaled Drug Candidate for Uncontrolled Asthma Why did we design this? What We Know Regeneron/Sanofi’s dupilumab (systemically administered anti-IL-4Ra antibody) has demonstrated the following: Reduction in biomarker (FeNO*) Improved lung function Exacerbation Reduction & Steroid Sparing 67% 80% reduction in avg. reduction high-eosinophil in corticosteroid patients use *Fractional exhaled nitric oxide What We Are Testing • Is this a local phenomenon? • First-in-man study underway via inhaled delivery 10
Preclinical In Vivo PoC Supports Clinical Development • First inhaled Anticalin protein to potently engage the highly-validated asthma target, IL-4Ra • Localized target engagement in lung tissue supports a rationale for a potential convenient, low-dose, low- cost alternative to systemically-administered antibodies • Preclinical in vivo PoC for pulmonary delivery at doses supportive of daily administration Total and differential cell counts in OVA Lung model Histopathology hIL-13-induced increases in eotaxin Control 48-hr gene expression Percentage inhibition of lung inflammatory cells 06 6 10 48hr after OVA challenge 78% 71% 79% 66% 5 10 06 4 10 06 3 10 06 2 10 06 expression Cell differential Cell ** ** PRS-060 48-hr 06 1 10 in eotaxin Change Fold ** 0 * Total Macrophages Eosinophils Lymphocytes 48hr timepoint Anticaln control *p<0.05, **p<0.001 compared with control TLPC134, (TLPC134) unpaired two-tailed t test (n=9-10); data are Mean SEM PRS-060 Inhibits the influx of key inflammatory cells 24-hr duration of action at doses both in lavage fluid and lung tissue feasible for inhalation 11
PRS-060 Phase I Trial Single Ascending Multiple Ascending Dose Dose Dosing patients with mild asthma, Healthy volunteers elevated FeNO at baseline Initiated in December 2017 Initiated in July 2018 Evaluating safety, tolerability, PK, Study completed PD and will also evaluate FeNO reduction vs. placebo Safe and well tolerated in single Pieris is sponsoring the trial, dose administration ranging from AstraZeneca is reimbursing Pieris 0.25-400mg for all associated costs 12
