Pieris Pharmaceuticals Announces Strategy to Maximize Partnered Milestone and Royalty Potential

BOSTON, MA, March 27, 2024 – Pieris Pharmaceuticals, Inc. (Nasdaq:PIRS) provided a corporate update today announcing a strategy to maximize its ability to capture the potential milestones from its 4-1BB bispecific Mabcalin® (antibody-Anticalin fusion) protein immuno-oncology assets partnered with Pfizer (formerly Seagen), Boston Pharmaceuticals, and Servier. After considering an extensive range of options, the Company's Board of Directors decided to implement this new strategy along with relevant cost-saving measures that are expected to extend the Company’s cash runway into 2027. 

The Company’s strategic review process has focused on maximizing stockholder value, which includes the preservation of potential milestone and royalty payments the Company is eligible to receive. Management and the Board of Directors evaluated a broad spectrum of potential options, including asset in-licensing, out-licensing, royalty monetization, strategic transactions (including reverse mergers, strategic mergers, and sale), and liquidation. With the assistance of the Company’s retained strategic advisor, Stifel, Nicolaus & Company, more than 500 companies were contacted regarding a strategic transaction, and the Company underwent a robust process to identify and negotiate with a select number of final candidates. The Company entered into extended exclusivity with one party contemplating a strategic merger, which centered on that party’s interest in developing the Company’s clinical-stage asset cinrebafusp alfa, but after extensive diligence and negotiations, that counterparty was unable to secure adequate capitalization and offer acceptable terms. The Company ultimately determined that the Company’s planned repositioning offers the best opportunity to maximize stockholder value.

“After an extensive review of strategic alternatives, our Board has determined that retaining the value of future milestone and royalty potential, which could result in up to $75 million of milestone payments during the next several years, as well as potential significant downstream milestones and royalty economics is key to maximizing value for our shareholders,” said James Geraghty, Chairman of the Board of Directors. “Implementing a lean business model with substantially reduced operating expenses results in an expected cash runway into at least 2027, while offering risk-mitigated diversification with high quality partners. Finally, on behalf of the full board, I want to express our gratitude to our employees for all their contributions and express to our investors our commitment to maximize shareholder value going forward."

In support of optimizing potential milestones and royalties, the Company's strategic repositioning includes:

“A compelling feature of this new strategy is its planned self-funded nature, offering the opportunity to capture meaningful future milestones and royalties through multiple partnered programs that are fully funded by third parties,” commented Stephen Yoder, President and Chief Executive Officer. Mr. Yoder continued, “The new strategy will also facilitate the potential to pursue milestone and royalty monetization agreements with third parties to possibly accelerate cash distributions to shareholders.”

Since initiating the strategic review in July 2023, the Company implemented several steps, including scaling back operational costs, inclusive of associated headcount reductions, ceasing development of PRS-220 and PRS-400 within its respiratory franchise, and suspending investments associated with co-development of partnered assets. The Company has also eliminated its material long-term obligations through the previously disclosed termination of its lease obligation in Germany, while simultaneously continuing to improve its cash position through the sale of its laboratory and office equipment.

As previously disclosed, the Company remains eligible to receive contingent milestone and royalty payments across its partnered 4-1BB bispecific Mabcalin protein franchise resulting from its partnerships with Pfizer, Boston Pharmaceuticals, and Servier. More specifically:

In addition to alliance management activities for the partnered programs above, the Company remains committed to trying to obtain value for its products in prior development, including cinrebafusp alfa, as well as proprietary platform capabilities by pursuing potential out-licensing or sale transactions. In addition to pursuing possible monetization of the projected royalty and milestone payments at attractive valuations, the Company may also, from time-to-time, opportunistically consider other options that it believes may increase stockholder value.

We can provide no assurance that the Company will receive any potential milestone or royalty payments or on the timing of any such milestone or royalty payments that may become due, or that any potential strategic transactions will occur.

As of December 31, 2023, the Company had $26.4 million in cash and investments. The Company does not expect to have any future financing requirements to achieve the near-term milestone potential of its partnered programs. The Company may consider cash dividends as and when milestone or other payments are received if the Company determines there is sufficient cash and investments to achieve the Company’s near and long-term objectives.
