How Integral Diagnostics’ Merger and Tech Drive 34% Revenue Surge

Strong FY25 Performance Anchored by Capitol Merger

Integral Diagnostics Limited (IDX) closed FY25 on a high note, reporting a 33.7% jump in revenue to $628 million, buoyed by the December 2024 merger with Capitol Health. This strategic consolidation has not only expanded IDX’s footprint to 145 clinics across Australia and New Zealand but also accelerated operational efficiencies and patient care improvements.

The merger integration has outperformed initial expectations, delivering $14 million in annualised synergies, well above the previously forecasted $10 million. These gains stem from enhanced procurement, streamlined administrative processes, and the rapid scaling of IDX’s teleradiology arm, IDXt.

Teleradiology and Technology Driving Growth

IDXt, the company’s 24/7 teleradiology service, has been a standout performer, growing its radiologist base to 114 and maintaining a compound annual growth rate above 30%. This unit’s flexible work model appeals to radiologists seeking control over their schedules and specialties, positioning IDX as a leader in digital diagnostic services.

Technological adoption, including AI-assisted imaging and digital patient pathways such as e-referrals and online appointments, has helped IDX overcome clinical skill shortages and inflationary pressures, particularly in regional areas. These innovations have improved turnaround times and patient outcomes, reinforcing IDX’s commitment to its core value of putting patients first.

Strategic Expansion and Industry Tailwinds

During FY25, IDX opened five new greenfield clinics and upgraded two facilities to state-of-the-art standards, further strengthening its market presence. The company also benefits from favorable industry dynamics, including Medicare indexation of 2.4%, MRI deregulation expanding full Medicare eligibility, and the launch of the National Lung Cancer Screening Program, which is expected to increase demand for advanced imaging modalities like PET-CT and MRI.

Additionally, the expansion of the GP Bulk Billing Practice Incentive Program from November 2025 is anticipated to boost GP visits and radiology referrals, especially in regional areas where benefits are two to three times higher than urban centers.

Leadership Transition and Future Outlook

After eight years at the helm, CEO Dr Ian Kadish announced he will retire at the end of FY26, leaving behind a transformed company that has grown from a regional practice to Australasia’s second-largest radiology network with a market capitalization nearing $1 billion. Under his leadership, IDX has delivered consistent dividend growth and enhanced shareholder value while positively impacting millions of patients.

Looking ahead, IDX expects continued revenue and margin expansion, projecting an operating EBITDA margin of around 21% for FY26. The company plans to maintain disciplined capital expenditure between $45 million and $55 million, focus on organic growth, and pursue further merger and acquisition opportunities amid ongoing industry consolidation.
