• Preliminary full year 2024 net revenues of $605 million and fourth quarter net revenues of $161 million
• Novocure to present at the 43^rd Annual J.P. Morgan Healthcare Conference at 9:00 a.m. PST on Wednesday, January 15, 2025

BAAR, Switzerland / Jan 13, 2025 / Business Wire / Novocure (NASDAQ: NVCR) today reported preliminary unaudited financial and operational results for the quarter and full year ended December 31, 2024. Novocure is a global oncology company working to extend survival in some of the most aggressive forms of cancer by developing and commercializing its innovative therapy, Tumor Treating Fields (TTFields).

“Novocure is at an exciting inflection point as we continue to expand our multi-indication TTFields treatment platform. In 2024, we brought Optune Gio^® to more than 4,000 glioblastoma patients across the globe, earned FDA approval and launched Optune Lua^® in non-small cell lung cancer in the U.S., announced two additional successful Phase 3 trial readouts and released our next generation arrays,” said Ashley Cordova, Chief Executive Officer. “With two additional indication launches on the horizon, we are well positioned for 2025 and beyond. This progress demonstrates our steadfast commitment to our patient-forward mission: together with our patients, we strive to extend survival in some of the most aggressive forms of cancer.”

Financial updates for the year and fourth quarter ended December 31, 2024*:

• Total preliminary net revenues for the year were $605.2 million, an increase of 19% compared to the prior year.
• 2024 growth was primarily driven by our successful launch in France and significantly improved approval rates in the U.S., which are now reflected in our revenue baseline. 2025 net revenue growth is expected to closely reflect growth in Optune Gio active patients.
• Total preliminary net revenues for the fourth quarter were $161.3 million, an increase of 21% compared to the same period in 2023.
  • The U.S., Germany, France and Japan contributed $107.2 million, $17.7 million, $16.0 million and $8.5 million, respectively, with other active markets contributing $9.9 million.
  • Revenue in Greater China from Novocure’s partnership with Zai Lab totaled $2.0 million.
  • Improved approval rates in the U.S. resulted in $8.3 million of increased net revenue from prior period claims during the quarter, which we believe should not be considered in our 2025 baseline. This is in addition to the $14.0 million of increased revenue from prior period claims disclosed through the third quarter.
• Cash, cash equivalents and short-term investments were $959.9 million as of December 31, 2024.

Operational updates for the fourth quarter ended December 31, 2024:

• As of December 31, 2024, there were 4,126 total active patients on TTFields therapy globally.
• 1,520 Optune Gio prescriptions were received in the quarter, consistent with the same period in 2023. Optune Gio prescriptions from the U.S., Germany, France and Japan contributed 897; 190; 194 and 109 prescriptions, respectively, with the remaining 130 prescriptions received from other active markets.
• As of December 31, 2024, there were 4,077 active Optune Gio patients on therapy. Active Optune Gio patients from the U.S., Germany, France and Japan contributed 2,161; 564; 426 and 420 active patients, respectively, with the remaining 506 active patients contributed by other active markets.
• On October 15, 2024, Optune Lua was approved by the U.S. Food and Drug Administration (FDA) for the treatment of metastatic non-small cell lung cancer (NSCLC) concurrently with PD-1/PD-L1 inhibitors or docetaxel, in adults who have progressed on or after a platinum-based regimen. As of December 31, 2024, 52 Optune Lua prescriptions were received for NSCLC.
• As of December 31, 2024, there were 20 active NSCLC patients on Optune Lua. Additionally, there were 29 active mesothelioma patients on Optune Lua around the globe.
• In Q1 2026, Novocure intends to stop reporting new prescriptions and focus on active patients by indication and material market as the key operating statistic.

Fourth quarter and recent updates and achievements:

• In October, the FDA granted Breakthrough Device designation for the use of TTFields therapy for brain metastases from non-small cell lung cancer. Breakthrough Device designation provides more frequent, faster and interactive access to the FDA review team and senior management during the review process, priority review of marketing applications upon filing, and expedited review of pre-Premarket Approval Application (PMA) manufacturing and quality systems compliance inspections.
• In October, the FDA approved Novocure’s new Head Flexible Electrode (HFE) transducer arrays for use with Optune Gio for the treatment of adult patients with glioblastoma (GBM).
• In December, the company announced the Phase 3 PANOVA-3 clinical trial met its primary endpoint, demonstrating a statistically significant improvement in overall survival for patients with unresectable, locally advanced pancreatic cancer. Novocure plans to submit the full data for presentation at an upcoming medical congress.
• In December, the FDA granted Breakthrough Device designation for the use of TTFields therapy for the treatment of unresectable, locally advanced pancreatic cancer.

If you have newly diagnosed GBM, Optune Gio is used together with a chemotherapy called temozolomide (TMZ) if:

• Your cancer is confirmed by your healthcare professional AND
• You have had surgery to remove as much of the tumor as possible

Recurrent GBM

If your tumor has come back, Optune Gio can be used alone as an alternative to standard medical therapy if:

• You have tried surgery and radiation and they did not work or are no longer working AND
• You have tried chemotherapy and your GBM has been confirmed by your healthcare professional

Who should not use Optune Gio?

Optune Gio is not for everyone. Talk to your doctor if you have:

• An implanted medical device (programmable shunt), skull defect (missing bone with no replacement), or bullet fragment. Optune Gio has not been tested in people with implanted electronic devices, which may cause the devices not to work properly, and Optune Gio has not been tested in people with skull defects or bullet fragments, which may cause Optune Gio not to work properly
• A known sensitivity to conductive hydrogels (the gel on the arrays placed on the scalp like the ones used on EKGs). When Optune Gio comes into contact with the skin, it may cause more redness and itching or may rarely cause a life-threatening allergic reaction

Do not use Optune Gio if you are pregnant or are planning to become pregnant. It is not known if Optune Gio is safe or effective during pregnancy.

What are the possible side effects of Optune Gio?

Most common side effects of Optune Gio when used together with chemotherapy (temozolomide, or TMZ) were low blood platelet count, nausea, constipation, vomiting, tiredness, scalp irritation from the device, headache, seizure, and depression.
