Thank you, Frank. We closed 2025 with continued momentum, delivering record net revenue for both the quarter and full year. Fourth quarter net revenue was $174 million, and full year net revenue totaled $655 million, representing 8% year-over-year growth for both periods. Growth was primarily driven by continued expansion in ex-U.S. markets, particularly Germany, France, and Japan, reflecting solid underlying demand and increased active patient count. Foreign exchange provided a tailwind of approximately $5 million in Q4 and $11 million for the full year compared to 2024. We recognized $3.5 million from Optune Lua claims in the quarter, including $2.4 million from non-small cell lung cancer. For the full year, Optune Lua revenue was $10.4 million, including $5.8 million from non-small cell lung cancer patients. I would also like to briefly address the recent Medicare billing situation. Earlier this month, CMS notified us that our billing privileges were halted due to an administrative issue identified during the DME supplier revalidation process. We engaged with the agency quickly, submitted a corrective action plan the following business day, and completed our required reinspection. Two days ago, we were notified that CMS rescinded the revocation and directed that our Medicare enrollment and billing privileges be reinstated retroactively to December 17, 2025. As a result, we do not expect any negative impact on revenue recognition from this matter. We are pleased that the issue is resolved and are appreciative of the agency's partnership in addressing the issue swiftly. Looking ahead to 2026. This morning, we issued annual net revenue guidance at constant exchange rates of $675 million to $705 million, representing year-over-year growth between 3% and 8%. This assumes Optune Gio net revenue growth in the low to mid-single digits and net revenue contributions from non-GBM products of $15 million to $25 million compared to $10 million in 2025. Moving down the P&L. Fourth quarter gross margin was 76% and 75% for the full year compared to 79% and 77% for the fourth quarter and full year 2024. The decrease was primarily driven by a decrease in prior period collections in the U.S. and increased costs associated with the HIV rates and tariffs. For 2026, we expect gross margin in the mid-70s percentage range. Research and development costs in the quarter were $61 million, an increase of 19% from the same period last year, and $225 million for the full year, an increase of 7%. The quarterly increase was driven by increased costs related to the KEYNOTE-58 and LUNAR-2 Phase III trials and regulatory costs. Sales and marketing expenses in the quarter were $69 million, an increase of 2% from Q4 2024, and full year sales and marketing expenses were $240 million, flat year-over-year. The increase in the quarter was driven by increased marketing activities related to new indications. G&A expenses for the fourth quarter were $43 million, a decrease of 41%, and $178 million for the full year, a decrease of 6% from 2024. The primary driver for the quarter was lower share-based compensation expenses related to 2020 PSUs triggered by the approval of Optune Lua in 2024. As noted in the 10-K today, we will have a similar charge in Q1 triggered by the Optune Pax approval. Net loss for the quarter was $24 million with a loss per share of $0.22. Full-year net loss was $136 million or $1.22 per share. Adjusted EBITDA in the quarter was negative $16 million and negative $34 million for the full year. Our cash and investment balance at the end of Q4 was $448 million. In the fourth quarter, we repaid $561 million of convertible notes in cash. We believe our current funds available, coupled with diligent expense management, will provide the necessary bridge as we bring new revenue streams online. Therefore, we have decided not to go beyond the $200 million already drawn from our current credit facility. As we look ahead to 2026, we are determined to make material progress towards our goal of driving profitable growth in the coming years. This morning, we issued adjusted EBITDA guidance of negative $20 million to breakeven for full year 2026. Overall, this reflects an acceleration of our plans to achieve adjusted EBITDA breakeven, driven by both our expectations of revenue growth as well as diligent expense management across the organization. With that, I'll turn the call back to the operator for Q&A.
