Forward Looking Statements Statements in this presentation that are not descriptions of historical facts are forward-looking statements that are based on management’s current expectations and assumptions and are subject to risks and uncertainties. In some cases, you can identify forward-looking statements by terminology including “anticipates,” “believes,” “can,” “continue,” “could,” “estimates,” “expects,” “intends,” “may,” “plans,” “potential,” “predicts,” “projects,” “should,” “will,” “would” or the negative of these terms or other comparable terminology. Factors that could cause actual results to differ materially from those currently anticipated include, without limitation, risks relating to the results of our research and development activities, including uncertainties relating to the discovery of potential drug candidates and the preclinical and clinical testing of our drug candidates; the early stage of our drug candidates presently under development; our ability to obtain and, if obtained, maintain regulatory approval of our current drug candidates and any of our other future drug candidates; our need for substantial additional funds in order to continue our operations and the uncertainty of whether we will be able to obtain the funding we need; our future financial performance; our ability to retain or hire key scientific or management personnel; our ability to protect our intellectual property rights that are valuable to our business, including patent and other intellectual property rights; our dependence on third-party manufacturers, suppliers, research organizations, testing laboratories and other potential collaborators; our ability to successfully market and sell our drug candidates in the future as needed; the size and growth of the potential markets for any of our approved drug candidates, and the rate and degree of market acceptance of any of our approved drug candidates; developments and projections relating to our competitors and our industry; our ability to establish collaborations; our expectations regarding the time which we will be an emerging growth company under the JOBS Act; our use of proceeds from this offering; regulatory developments in the U.S. and foreign countries; and other factors that are described more fully in our Annual Report on form 10-K filed with the SEC on March 30, 2017. In light of these risks, uncertainties and assumptions, the forward-looking statements regarding future events and circumstances discussed in this report may not occur and actual results could differ materially and adversely from those anticipated or implied in the forward-looking statements. You should not rely upon forward- looking statements as predictions of future events. The forward-looking statements included in this presentation speak only as of the date hereof, and except as required by law, we undertake no obligation to update publicly any forward-looking statements for any reason after the date of this presentation to conform these statements to actual results or to changes in our expectations. 2

Immuno-oncology Franchise 6 Proprietary Clinical • PRS-343 - First-in-class bispecific to preferentially activate T cells in the tumor microenvironment (TME) - In Phase I – HER2-positive patients - Safety and PD data in 20184-1BB-targeting Ac HER2-targeting mAb Checkpoint/costim Acs Checkpoint/costim mAbs Servier Alliance • 5-program deal (all bispecifics) • Pieris retains full U.S. rights for 3 out of 5 programs • $31M upfront payment • $1.8B milestone potential • Up to low double-digit royalties on non-codev products Proprietary Research • Multiple ongoing research and preclinical programs with bispecific and multi-specific antibody/Anticalin protein constructs


 
PRS-343: Why did we design this? 4-1BB systemically agonizing antibody has shown mono-therapy efficacy yet significant toxicity in the clinic (narrow therapeutic window) PRS-343 preferentially agonizes 4-1BB in the TME by using its anti-HER2 component to drive drug clustering and, therefore, 4-1BB cross-linking 7 4-1BB-targeting Acs HER2-targeting mAb


 
PRS-343 Targets Local Biology 4-1BB (CD137) – Key Costimulatory Target • Marker for tumor-specific T cells in TME • Ameliorates T cell exhaustion • Critical for T cell expansion • Induces anti-tumor cytolytic activity • Drives central memory T cell differentiation for sustained response 8 HER2 – Strongly Validated Tumor Target • Restricted expression on normal tissue • Multiple HER2+ tumors with high-unmet need - Bladder, Gastric, Breast and several others - Mediates drug mobilization and immune receptor activation within the tumor bed High HER2 Expression Clustering & T cell Activation T cell costimulation in TME Tumor-specific T cell


 
PRS-343 Shows Bifunctional Activity – Dose-dependent Tumor Growth Inhibition & CD8(+)TIL Expansion in HER2+ Ovarian Cancer Model • PRS-343 shows dose-dependent tumor growth inhibition in HER2-sensitive model • PRS-343 leads to strong and dose-dependent lymphocyte infiltration in tumors; monospecific anti-HER2 mAb (IgG4 backbone) inhibits tumor growth but lacks this immuno-stimulatory activity • Monospecific anti-4-1BB benchmark mAb shows insignificant response compared to isotype control and no significant tumor infiltration of lymphocytes 9 Tumor growth (median) SK-OV-3 tumor model Incomplete group due to mortality 100µg Isotype Ctrl 100µg PRS-343 100µg Anti-4-1BB 0 10 20 30 F re q u en cy [ % ] C D 3 C D 45 C D 4 C D 8 0 10 20 30 F re q u en cy [ % ] C D 3 C D 45 C D 4 C D 8 0 10 20 30 F re q u en cy [ % ] C D 3 C D 45 C D 4 C D 8 hCD4hCD3 hCD8 Plot TIL phenotyping by IHC


 
PRS-343 Avoids Unwanted Effect of Peripheral T Cell Activation, Unlike Systemically Agonistic 4-1BB mAb • Toxicity observed with anti-4-1BB mAb likely corresponds to indiscriminate peripheral T cell activation • Unlike PRS-343, anti-4-1BB benchmark mAb shows accelerated graft-versus-host-disease with significant mortality in line with literature data1 10 Survival % CD8+ of CD45+ 1Sanmamed et al., Cancer Res. 2015 Sep 1;75(17):3466-78.

PRS-060 For Uncontrolled Asthma: Why Did We Design This? 13 What We Know Regeneron/Sanofi’s Dupilumab (systemically administered anti-IL-4Ra) has demonstrated the following: 67% reduction in high-EO patients What We Are Testing • Is this a local phenomenon? • First-in-man study underway Reduction in FeNO Exacerbation Reduction Steroid Sparing 80% avg. reduction in corticosteroid use Improved lung function


 
PRS-080 for Anemia – Why We Made This? 14 What We Know Hepcidin is up-regulated in functional iron deficiency anemia Antagonizing hepcidin with single-dose PRS-080 in CKD5 patients led to Fe mobilization What We Are Testing Will antagonizing hepcidin with PRS-080 lead to a hemoglobin increase after 5 q/wk. doses? 0 10 20 30 40 50 60 0 48 96 144 Mean Iron Concentrations Se ru m Ir on [µ M ] Ph Ib SAD in CKD5 patients • Phase IIa study underway testing two dose cohorts: 4mg/kg and 8mg/kg vs. pbo • Data expected 2H18
