American Shared Hospital Services

American Shared Hospital Services finances and operates advanced radiation therapy technology through two models: leasing medical equipment to hospitals and running its own radiation therapy centers that bill patients and payors directly. Its installed base includes Gamma Knife stereotactic radiosurgery systems, LINAC radiation therapy systems, and a proton beam radiation therapy (PBRT) system under contract arrangements. In the leasing segment, revenue is tied to procedure volumes via fee-per-use pricing or revenue-sharing on hospital reimbursements, typically under long-term contracts. In direct patient services, the company operates single-unit centers in Rhode Island and international facilities in Peru, Ecuador, and Mexico, where it provides radiation treatments as the principal under patient contracts.

  • U.S. hospitals/health systems (leasing)primary

    Lease Gamma Knife, LINAC, and PBRT capacity via fee-per-use or revenue-sharing to provide radiation therapy without owning the equipment outright.

  • U.S. patients at company-operated centers (direct patient services)secondary

    Receive radiation therapy at the Rhode Island facilities where the company acts as principal and recognizes treatment revenue at the time of service.

  • International patients at company-operated centersemerging

    Receive Gamma Knife or LINAC treatments at facilities in Peru, Ecuador, and Mexico, expanding the direct patient services model outside the U.S.

  • Equipment OEM/service vendors (ecosystem partners)secondary

    Provide maintenance and service coverage (e.g., Elekta, Mevion) that supports uptime and contractual performance for leased and owned systems.

Operations are primarily U.S.-based, with leased Gamma Knife, LINAC, and PBRT systems under contract with domestic...

  • Rhode Island: three stand-alone radiation therapy centers (direct services)
  • Peru: Lima Gamma Knife single-unit facility (direct services)
  • Ecuador: Guayaquil Gamma Knife single-unit facility (direct services)
  • Mexico: Puebla single-unit LINAC facility (direct services; started July 2024)
  • U.S. reimbursement (CMS) is a key driver of leasing economics

Scale direct patient services footprintmedium-term

Owned centers allow the company to contract directly with patients and capture economics beyond equipment leasing.

02
Stabilize and optimize leasing utilizationshort-term

Leasing revenue is driven by procedure volume and reimbursement under fee-per-use and revenue-sharing arrangements.

Ensure equipment uptime and cost control through service arrangementsshort-term

Service commitments and maintenance execution affect capacity, patient throughput, and profitability at both leased and owned sites.

Revenue is highly sensitive to procedure volumes at each site, because leasing contracts generally lack guaranteed...

Procedure volume declines reduce revenue and profitability

Leasing revenue is recognized per procedure or as a share of reimbursement, and direct patient services depend on patient throughput; lower volumes drove segment losses in the quarter discussed.

Reimbursement and coding changes (CMS/commercial) pressure economics

Contract receipts are tied to reimbursement levels (directly for revenue share and indirectly for demand), so payer policy changes can reduce revenue per treatment.

Service and uptime risk from reliance on third-party maintenance

The company has significant service commitments and depends on vendors to keep systems operational; downtime reduces procedures and can raise costs.
