Accuray

Robotics-assisted, image-guided radiotherapy for cancer

Overview

Accuray provides cancer-care technology that uses robotics and image guidance to deliver precise, non-invasive radiation treatments. Its flagship CyberKnife system places a robotic arm around the patient to aim highly focused radiation beams at tumors anywhere in the body, performing radiosurgery without surgery. In 2011 it expanded its product line by acquiring TomoTherapy, adding a helical radiation therapy platform to its portfolio, broadening the ways clinicians can treat cancer. The company differentiates itself by combining robotics with real-time imaging to track tumors and adjust treatment in real time, and by offering a broader, multi-product radiation oncology system rather than a single device. Accuray’s goal is to provide effective, non-invasive cancer treatments to patients worldwide, growing its global installed base and advancing access to precise radiation therapy.

Accuray secures $55M financing, cuts costs by $20M amid China headwinds and tariff uncertainty

Accuray Incorporated reported fiscal 2026 results, describing the year as foundational for streamlining operations and reducing costs. Geopolitical tensions and tariff uncertainty in China contributed to approximately $58 million in product revenue decline. The company achieved $20 million in cost and margin improvements, exceeding its initial $12 million target. Service revenue grew 6% in Q4, driven by strategic pricing and an expanding installed base. Accuray is pivoting to a partner-centric model, using nonbinding letters of intent with Samsung Medison and Research Laboratories to accelerate innovation. The company completed a restructuring transaction with TCW Asset Management, converting $40 million of debt into preferred equity. Management is not providing fiscal 2027 guidance due to geopolitical uncertainty. The company expects approximately $15 million in additional annualised cost improvements and has secured a covenant holiday through December 2027.
