Management to Host Conference Call Today at 4:30 p.m. ET

MOUNTAIN VIEW, Calif. – August 12, 2026 – RenovoRx, Inc. (“RenovoRx” or the “Company”) (Nasdaq: RNXT), a life-sciences company developing innovative targeted oncology therapies and commercializing RenovoCath®, a patented, FDA-cleared drug-delivery device, today announced its financial results for the second quarter ended June 30, 2026, and provided shareholders with a business update highlighting continued commercial momentum and clinical progress.

“In the second quarter of 2026, we delivered record revenue and executed on all three of the milestones we set for the business: revenue growth with another record revenue quarter, commercial momentum evidenced by several cancer center activations, and expansion of the application of our technology beyond locally advanced pancreatic cancer (LAPC),” said Shaun Bagai, Chief Executive Officer of RenovoRx. “We generated quarterly revenue of $909,000, an increase of approximately 61% compared to the first quarter of 2026, and approximately 115% compared to the second quarter of 2025. Our strong first half performance gives us confidence that our second half revenue will exceed our original full year forecast. This outlook is driven by more active commercial cancer center customers, more patients treated via procedures with RenovoCath, and repeat ordering across our existing customer base.”

Mr. Bagai continued, “We ended the second quarter with 21 active commercial cancer center customers, an increase of more than 30% from the 16 centers reported at the time of our first quarter earnings call, and expanded our total commercial pipeline to 63 centers, including 42 additional centers progressing through evaluation, approval, and activation. We continue to see meaningful repeat utilization across our existing customer base, and for the first time, a treating physician chose RenovoCath to deliver therapy to a patient with a solid tumor beyond pancreatic cancer, marking an important, physician-driven expansion of the clinical application of our TAMP platform.”

“Looking ahead, we remain focused on executing against both our near-term commercial priorities and our long-term clinical objectives,” added Mr. Bagai. “Based on current trends, we expect third quarter revenue to surpass second-quarter revenue and set another record. We remain on track to meet or exceed our target of 36 active commercial cancer center customers by year end 2026."

"The recently announced enrollment completion of our Phase III TIGeR-PaC trial positions the majority of our trial sites to also transition to commercial use in the second half of the year. Reflecting our strong first half performance, we are raising and tightening the range for our full year revenue guidance. In short, we believe RenovoRx is building a durable, capital-efficient commercial business," said Mr. Bagai. "Management believe that reaching a quarterly

revenue run-rate of approximately $5 million would position RenovoRx at cash-flow break-even, and based on our current trajectory, our internal plan anticipates achieving break-even operations in the fourth quarter of 2027."

RenovoCath Commercialization Update

RenovoRx delivered its strongest quarterly revenue performance to date. Revenue totaled $909,000 for the second quarter, an increase of approximately 61% compared to the first quarter of 2026 and approximately 115% compared to the second quarter of 2025. Second quarter revenue alone represented approximately 83% of the Company’s total revenue generated in all of 2025. For the six months ended June 30, 2026, revenue totaled approximately $1.5 million. This growth reflects continued expansion of active commercial cancer center customers and increasing procedural utilization of RenovoCath across the Company’s growing base of commercial sites.

The Company’s commercial model is currently focused on activating new cancer center customers, which have been a source of recurring demand. RenovoRx ended the second quarter of 2026 with 21 active commercial cancer center customers, an increase of more than 30% from the 16 active customers reported at the time of the Company’s first quarter 2026 earnings call. RenovoRx is also advancing a customer pipeline of 42 additional centers in various stages of evaluation, approval, or activation. Combined with its 21 active customers, this represents a total of 63 centers in the Company’s commercial funnel, a 31% increase compared to the 48 total centers reported on its first quarter call. The Company remains on pace to meet or exceed its target of 36 active commercial cancer center customers by year end 2026. In addition, 15 Phase III TIGeR-PaC clinical trial sites are positioned to transition to commercial RenovoCath use, several of which have already begun doing so. These sites represent an anticipated and meaningful contributor to revenue in the second half of 2026.

RenovoRx continues to observe strong repeat ordering from existing customers, which the Company views as one of the clearest indicators of physician satisfaction and clinical utility in interventional oncology. As physicians incorporate RenovoCath into routine clinical practice, repeat utilization is expected to drive sustained revenue growth. Based on its current customer pipeline and trends to date, the Company expects third quarter 2026 revenue to exceed second quarter revenue which would represent another consecutive record revenue quarter.

Since receiving FDA 510(k) clearance, RenovoCath has been used in more than 900 successful procedures. RenovoRx continues to estimate that the initial total addressable market (TAM) for RenovoCath as a stand-alone device could translate into an approximately $400 million peak annual U.S. sales opportunity for RenovoRx. Over time, as the Company expands the platform into additional solid tumor indications, the Company believes it could unlock more than $1 billion in peak annual sales potential.

Expansion of RenovoCath Beyond Locally Advanced Pancreatic Cancer

In early August 2026, RenovoRx announced the first commercial clinical use of RenovoCath by an existing cancer center customer in the treatment of sarcoma, marking the expansion of its targeted drug-delivery device to solid tumors beyond pancreatic cancer. The case involved a physician who had previously treated LAPC patients using RenovoCath and returned to RenovoRx with a plan to use the catheter to treat sarcoma. The Company views this physician-driven adoption as a meaningful endorsement of RenovoCath’s potential as a standalone device across additional difficult-to-treat solid tumors within its FDA-cleared fields of use.

Ongoing Phase III TIGeR-PaC Trial Update

Recently, RenovoRx announced that it achieved full enrollment in its Phase III TIGeR-PaC trial evaluating intra-arterial delivery of intra-arterial gemcitabine (IAG) via the RenovoCath device for the treatment of LAPC. This significant milestone reflects successful patient recruitment, clinical execution, and collaboration among investigators and study teams evaluating IAG for LAPC, a difficult-to-treat cancer. The primary endpoint of the study is overall survival. TIGeR-PaC is designed to evaluate whether RenovoRx’s patented method of targeted

delivery of the chemotherapy gemcitabine improves patient survival, safety, and tolerability compared to the standard of care (systemic (intravenous) chemotherapy gemcitabine + Abraxane).

As of August 7, 2026, TIGeR-PaC trial investigators have been notified by RenovoRx that patient enrollment is closing. Completion of the trial is expected during the first half of 2027, after 86 events (i.e., patient deaths) have been observed. As of August 11, 2026, 78 events have occurred. Following completion of the trial, initial topline trial data is expected to be available during the second half of 2027.

With enrollment complete, RenovoRx is now focused on advancing toward final data analysis. These efforts build on the successful completion of the second interim analysis in 2025, after which the independent Data Monitoring Committee recommended continuation of the trial without modification. To preserve trial integrity, the Company elected to defer publication of interim data until study completion.

RenovoRx continues to view TIGeR-PaC as a critical long-term value driver, while emphasizing that its current commercial strategy is independent of the trial’s ultimate outcome and timeline.

Second Quarter 2026 and Subsequent Key Highlights

RenovoRx continued to execute on its dual commercial and clinical strategy during the second quarter of 2026 and the subsequent period, building real-world evidence base for its TAMP platform.

During the second quarter of 2026, several scientific data updates supported the use of intra-arterial gemcitabine delivery via TAMP in LAPC. A peer-reviewed case study by researchers at Moffitt Cancer Center, published in Radiology Case Reports, found that PET-CT imaging, rather than CT alone, showed a meaningful reduction in tumor metabolic activity after treatment. These findings suggest that PET imaging may help optimize monitoring of therapeutic response following TAMP-delivered treatment.

In addition, the PK sub-study of the TIGeR-PaC trial has been accepted and will be published in the near future in the Journal of Cancer Chemotherapy and Pharmacology. The findings support TAMP as a targeted delivery method for gemcitabine, demonstrating its potential to increase local drug potency while reducing systemic exposure and common side effects.

Finally, a peer-reviewed case series in Case Reports in Oncology from researchers at Hackensack Meridian Health’s Jersey Shore University’s Medical Center was accepted and will be published in the near future. The case series highlights their experience with the TAMP procedure in LAPC.

The ramping up of publication of the TAMP procedure by physicians, the Company believes is another sign of adoption as TAMP traverses from an experimental procedure to becoming a potential standard of care.

Cash Resources, History of Losses and Planned Activities

RenovoRx continued to build the evidence base for its TAMP platform through a multi-center post-marketing registry study generating real-world safety and efficacy data, as well as investigator-initiated trials (IITs) in borderline resectable and metastatic pancreatic cancer designed to achieve cost neutrality while broadening the platform’s evidence base. In the second quarter of 2026, the Company began supporting a new IIT in cholangiocarcinoma (bile duct cancer).

RenovoRx received FDA Orphan Drug Designation for oxaliplatin in the treatment of pancreatic cancer in the second quarter of 2026, further expanding the potential applications of its targeted drug-delivery platform.

Financial Highlights for the Second Quarter Ended June 30, 2026
