**Traws Pharma Provides Business Highlights and Reports Q1 2026 Financial Result** **s**

*Private financing of up to $60M offering of common stock (with $10M upfront) and milestone-based warrants expected to support operations into Q1 2027*

*Tivoxavir marboxil advancing towards a human influenza challenge trial as a once-monthly prophylactic agent*

*Advancing clinical candidates for the treatment of hantavirus infections*

NEWTOWN, PA, May 15, 2026 (GLOBE NEWSWIRE) – Traws Pharma, Inc. (NASDAQ: TRAW) ("Traws Pharma", "Traws" or "the Company"), a clinical-stage biopharmaceutical company developing novel therapies to target critical threats to human health from respiratory viral diseases, today provided recent business highlights and reported financial results for the quarter ended March 31, 2026. The highlights include updates on the Company's lead program, tivoxavir marboxil (TXM), in development for influenza prophylaxis, and its hantavirus drug development efforts.

"Q1 2026 was a period of meaningful progress for Traws. The recently announced private financing of up to $60 million in gross proceeds provides us with a clear runway into Q1 2027 and supports our ability to execute on our key programs. We are advancing TXM toward a human challenge trial as a once-monthly prophylactic agent against seasonal influenza, which is scheduled to be initiated in Q2 2026. Separately, we will be actively engaging with the FDA to resolve the clinical hold and enable initiation of global studies by year end," commented **Iain Dukes, MA, DPhil, Chief Executive Officer** of Traws Pharma. "Our pipeline now also includes a potential antiviral therapy for hantavirus. The recent outbreak<sup>1</sup> brought new attention to a disease with no approved treatments."

**Recent Highlights and Anticipated Milestones:**

**$60 Million Private Financing**

On April 15, 2026, TRAW announced an up to $60 million private investment in a public equity (PIPE) financing, including $10 million in gross proceeds at closing, with up to approximately $50 million of additional potential gross proceeds from milestone-based and three-year warrants. As described in the Company's 8K issued on April 15, 2026, the financing consists of the sale of 5,982,919 shares of common stock (or pre-funded warrants in lieu thereof) at a purchase price of $1.6730 per share.

The upfront gross proceeds and milestone-based warrants, along with the current cash and cash equivalents, are estimated to provide sufficient resources to fund company operations into Q1 2027 including completion of a human challenge trial to evaluate TXM as a once-monthly prophylactic agent for influenza prevention.

**Investigational Programs:**

**Tivoxavir Marboxil (TXM, influenza):** 

**Intended Indication and Market Potential**: Potential as a best-in-class once-monthly prophylactic for seasonal flu and potential inclusion in pandemic preparedness initiatives,<sup>2,3</sup> all-together, estimated to be a multi-billion-dollar opportunity.

**Next Steps:**

· **Completion of Phase 1 Bridging Study** – The ongoing Phase 1 Bridging Study, conducted under an open IND in Australia, is intended to evaluate if
the compressed tablet formulation provides 28-days of coverage.

· **MHRA Approval and Initiation of Challenge trial** – Following completion of the Phase 1 Bridging Study and receipt of MHRA approval, TRAW will conduct
a single-dose influenza virus challenge trial of TXM at hVIVO, a global leader in the conduct of human challenge studies for infectious
diseases and respiratory viruses, in the UK.

· **Efforts Ongoing to Resolve the Clinical Hold** – FDA placed the U.S. IND for TXM on clinical hold due to concerns with the toxicology data package.
The Company is preparing a comprehensive response, with the goal of resolving the hold and enabling initiation of global clinical studies
by year end.

**Hantavirus Program:**

**Intended Indication and Market Potential**: Hantavirus, a rodent-borne negative-strand RNA virus that typically results in a 30-50% fatality rate when transmitted to humans and which has been implicated as the cause of several cruise ship fatalities and serious illnesses in recent days<sup>1</sup>.

**Next Steps:** Traws plans to move rapidly to advance a clinical candidate for hantavirus treatment.

**Financial Results:** 

**Cash and cash equivalents:** As of March 31, 2026, the Company had cash and cash equivalents of approximately $3.1 million, compared to approximately $3.8 million as of December 31, 2025, excluding gross proceeds of up to approximately $60 million for a PIPE financing and milestone-based and three-year warrants which the Company completed on April 15, 2026. Based on current plans, the Company believes that its current cash balance, including net proceeds from the offering and milestone-based warrants, is sufficient to support planned expenses, including completion of the Challenge Study, into Q1 2027.

**Revenue** for the quarter ended March 31, 2026, was $0.0 million, compared to $0.06 million for the comparable period in 2025.

**Research and development (R&D) expense** for the quarter ended March 31, 2026, totaled $4.9 million, compared to $2.5 million for the comparable period in 2025. This increase of $2.4 million primarily relates to an increase in expenses related to completion of antiviral clinical trial milestones.

**General and administrative (G&A) expense** for the quarter ended March 31, 2026, totaled $2.0 million, compared to $2.8 million for the comparable period in 2025. This decrease of $0.7 million was primarily attributable to a decrease in professional and consulting fees.

**Change in fair value of warrant liability** for the quarter ended March 31, 2026, was an expense of $0.2 million, compared to other income of $26.5 million for the comparable period in 2025. The change for the three months ended March 31, 2025 is primarily attributable to remeasurement of the warrant liability upon amendment and partial exercise of the Pre-Funded Warrants and Series A Warrants, and the fair value of remaining Series A Warrants as of March 31, 2025.

**Net Income (loss)**: The net loss for the quarter ended March 31, 2026 was $7.1 million, or a net loss of $0.53 per basic and diluted common share. This compares to net income of $21.5 million, or net income of $2.17 per basic and $2.09 per diluted common share, for the quarter ended March 31, 2025.

**Shares Outstanding**: Traws had 15,150,669 shares of common stock outstanding as of May 12, 2026.

**About Tivoxavir Marboxil**

Tivoxavir marboxil (TXM) is an investigational oral, small molecule CAP-dependent endonuclease inhibitor designed to be administered as a single-dose prophylactic agent for seasonal influenza and treatment of pandemic/bird flu. It has shown potent *in vitro* activity against a range of influenza strains in preclinical studies, including a human isolate of the highly pathogenic avian flu H5N1 (bird flu). Consistent, positive preclinical data from three animal species indicate that a single dose of TXM demonstrated a therapeutic effect against H5N1 bird flu. Seasonal influenza represents an estimated multi-billion-dollar antiviral market opportunity, largely driven by global health organizations, practice guidelines and government tenders and inclusion in drug stock piling initiatives <sup>2,3</sup>, with upside potential from potential pandemic flu outbreaks including H5N1 bird flu.
