Tariffs, as of December 31. Currently, we do not expect a material change to our results of operations as a consequence of the latest U. S. Tariff actions. And we refer you to our 2025 press release and earnings materials as well as our Q2 twenty twenty five webcast slides which includes specifics regarding potential impacts on U. S. Tariffs. Now turning to our outlook. Assuming no circumstances occur beyond our control, such as foreign exchange, macroeconomic conditions, and changes to our currently applicable duties, including tariffs or other fees that could impact our business. We expect Q1 twenty twenty six worldwide revenues to be in the range of $1,010,000,000 to $1,030,000,000 up 3% to 5% year over year. We expect Q1 twenty twenty six clear aligner volume to be up mid single digits year over year. We expect Q1 twenty twenty six clear aligner average selling price to be up sequentially from favorable geographic mix. We expect systems and services revenue to be down sequentially consistent with our typical Q1 seasonality. We expect our Q1 twenty twenty six GAAP operating margin to be 12.4% to 12.8%, down sequentially and Q1 twenty twenty six non GAAP operating margin to be approximately 19.5%, consistent with Q1 seasonality. For fiscal twenty twenty six, we expect 2026 worldwide revenue growth to be up 3% to 4% year over year, We expect 2026 clear aligner volume growth to be up mid single digits year over year.

We expect our investments in capital expenditures for fiscal twenty twenty six to be $125,000,000 to $150,000,000 Capital expenditures primarily relate to technology upgrades additional manufacturing capacity, as well as maintenance. Q4 was a good finish to the year. With results that came in better than expected and reflect the continued strength of our business fundamentals. As we enter 2026, we are executing with focus and discipline, and we're encouraged by the progress we're seeing across the regions and key customer segments. Our confidence is grounded in the actions we're taking to actively manage the business, and drive growth through our core strategic priorities. Expanding international adoption, increasing orthodontic utilization part particularly among teens and kids, accelerating GP engagement, including restorative dentistry, and strengthening consumer demand conversion with greater emphasis on local last mile marketing. While the macro environment remains dynamic, we are cautiously cautiously optimistic. With a strong innovation road map, disciplined operational execution, and a global team committed to delivering for doctors and their patients we believe we are well positioned to deliver growth and value in 2026 and beyond. With that, I'll turn it back over to Joe for final comments.
