Novocure (NASDAQ: NVCR) today reported financial results for the first quarter that ended March 31, 2026. 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).

“This was a very strong start to the year for Novocure and we are pleased with the progress made across our commercial and clinical programs,” said Frank Leonard, CEO, Novocure. “We reached several key milestones in the first quarter and are eager to maintain this momentum as we approach numerous exciting catalysts later this year. Our focus remains on bringing Tumor Treating Fields therapy to patients diagnosed with some of the most aggressive forms of cancer, further exploring the use of our therapy to benefit patients in need, and achieving sustainable growth and profitability.”

Financial updates for the quarter ended March 31, 2026:

• Total net revenues for the quarter were $174.1 million, an increase of 12% compared to the same period in 2025. This increase was primarily driven by active patient growth in European markets.
  • The U.S., Germany, France and Japan contributed $96.0 million, $24.5 million, $22.9 million and $10.2 million, respectively, with other active markets contributing $15.7 million.
    • Net revenue from Germany benefitted from increased approval rates, including a one-time benefit of $2.5 million.
    • Net revenue from France benefitted from contract performance improvements, including a one-time benefit of $1 million.
  • Revenue in Greater China from Novocure’s partnership with Zai Lab totaled $4.8 million.
  • Recognized revenue from Optune Lua® in the quarter was $3.1 million.
• Gross margin for the quarter was 78% compared to 75% in the prior year. The increase was primarily driven by lower array costs resulting from improved array utilization and lower supplier prices.
• Research, development and clinical study expenses for the quarter were $58.3 million, an increase of 8% from the same period in 2025. This was primarily driven by increased costs associated with patient recruitment in the Phase 3 KEYNOTE D58 clinical trial.
• Sales and marketing expenses for the quarter were $58.4 million, an increase of 5% compared to the same period in 2025. This was primarily driven by costs associated with the launch of Optune Pax® in the U.S. and Optune Lua in Japan.
• General and administrative expenses for the quarter were $85.9 million, an increase of 92% compared to the same period in 2025. This increase was primarily driven by a $43 million share-based compensation expense triggered by the U.S. FDA approval of Optune Pax. This non-cash expense is reported in accordance with U.S. GAAP, but the associated grant did not vest and shares were not distributed.
• Net loss for the quarter was $71.1 million with loss per share of $0.62.
• Adjusted EBITDA* for the quarter was $(0.3) million.
• Cash, cash equivalents and short-term investments were $432.0 million as of March 31, 2026.

  • The U.S., Germany, France and Japan contributed 106; 47; 2 and 6 active patients, respectively, with 4 active patients contributed by other active markets.
• Optune Pax
  • 169 prescriptions for Optune Pax were received in the quarter.

  • Novocure announced the topline results from the Phase 2 PANOVA-4 clinical trial, evaluating TTFields therapy concomitant with atezolizumab (Tecentriq®), gemcitabine and nab-paclitaxel as a first-line treatment for metastatic pancreatic cancer.

*Non-GAAP Financial Measurements

We measure our performance based upon a non-U.S. GAAP measurement of earnings before interest, taxes, depreciation, amortization and shared-based compensation ("Adjusted EBITDA"). We believe Adjusted EBITDA is useful to investors in evaluating our operating performance because it helps investors compare the results of our operations from period to period by removing the impact of earnings attributable to our capital structure, tax rate and material non-cash items, specifically share-based compensation.
