Integral Diagnostics

What Integral Diagnostics does

Integral Diagnostics Limited (ASX: IDX) is an Australian-headquartered, publicly listed diagnostic imaging services provider operating a network of 155 clinics across six Australian states and New Zealand, supported by 350+ radiologists and 3,000+ employees following the December 2024 merger with Capitol Health. The company delivers a full range of medical imaging modalities — X-ray, CT (including dual-source CT), MRI, ultrasound, mammography, PET-CT, nuclear medicine, bone densitometry, dental imaging and interventional procedures — through regional brands such as Capital Radiology, Apex Radiology, Lake Imaging, South Coast Radiology, Radiology Tasmania, and Astra Radiology in New Zealand. Its technology stack combines PACS/RIS for image management with the Aidoc aiOS AI platform (deployed across 185 facilities, processing 600,000+ cases since 2019) for automated critical-pathology flagging, the IDXt home-based teleradiology platform (124 radiologists) for after-hours and overflow reporting, and a Deloitte-led centralized technology modernization initiative.

The business model is primarily fee-for-service diagnostic imaging reimbursed through Australia's Medicare Benefits Schedule, New Zealand's Accident Compensation Corporation, private health insurers, and government screening programs such as the National Lung Cancer Screening Program (NLCSP) launched July 2025. Revenue streams include patient imaging services billed through referrals (the dominant channel), hospital and enterprise contracts for on-site radiology and teleradiology reporting (via IDXt), and emerging consumer-paid services such as Astra's Auckland whole-body wellness scanning. Distribution combines a physical owned-clinic network with B2B hospital contracts and government-program participation (Chest Scan Australia covers 85 NLCSP-eligible sites). Customers are long-tail referred patients and a meaningful but diversified base of public and private hospitals.

In H1 FY2026, the company reported revenue of AUD 393.5 million (up 55.6% following the Capitol merger), operating EBITDA of AUD 81.1 million (up 75.6%) at a 20.6% margin (+230 bps), and net income of AUD 14.0 million, with FY2026 EBITDA margin guidance of 21% and 7.5% organic growth. Net debt-to-EBITDA improved to 2.5x. The company is targeting the second-largest diagnostic imaging position in Australia and is investing in regional expansion (new clinics in Tasmania, Victoria and South Australia), AI capability scaling with Aidoc, and a wholesale technology modernization with Deloitte.
