Rimini Street Awarded CANUT Third-Party Support Framework Agreement

This framework agreement provides all entities subject to the French Public Procurement Code with simplified access to a support alternative enabling them to control their costs, preserve their freedom of technological choice and free themselves from vendor-imposed upgrade cycles

LAS VEGAS – November 4, 2026 – Rimini Street, Inc. (Nasdaq: RMNI), the Software Support and Agentic AI ERP Company™ and the leading third-party support provider for Oracle, SAP and VMware software, today announced that it had been selected as the awardee of the third-party support service lots (TMA) by CANUT, the French public purchasing center specializing in digital technology and telecommunications.

Eligible public organizations subject to the French Public Procurement Code can now benefit from Rimini Street services for their Oracle, SAP, VMware and IBM environments, without having to go through a lengthy individual tender process. Through Rimini Support™, organizations gain access to a support alternative enabling them to significantly reduce their historical support costs, improve service quality and support responsiveness, while retaining their perpetual licenses and control over the evolution of their existing systems.

The Benefits of Rimini Support™ for the Public Sector

In the context of government initiatives aimed at strengthening French digital sovereignty and reducing dependence on major international vendors, many public administrations and organizations are re-examining their application strategies. They face growing constraints: increasing maintenance costs, vendor-dictated roadmaps and less control over the evolution of their systems.

Rimini Street offers a proven alternative to the traditional vendor maintenance model. By simply replacing their current support contract with Rimini Support™, organizations can benefit from:

Immediate and significant savings on annual support fees
Custom code fixes at no additional cost
Tax, legal and regulatory updates for compliance
A named Primary Support Engineer, backed by a team of more than 800 experts providing 24/7/365 coverage
Guaranteed 10-minute response time for priority cases, delivered on average in less than 2 minutes
Commitment to resolution within 4 hours for critical cases, with proactive follow-up every two hours
Human-centered support experience, enhanced by automation and advanced analytics based on proprietary patented AI

“For public organizations, the essential criteria are value creation, regulatory compliance and the ability to react quickly when needed, while retaining genuine freedom of decision,” said Hervé Grandjean, IT buyer within CANUT. “The offering proposed by Rimini Street meets these expectations. Thanks to this pre-qualified solution available through CANUT, public and private non-profit organizations now have a concrete alternative to traditional support models, which are often characterized by dependence on a single vendor and a lack of flexibility. The potential savings can be immediately reinvested in high-value modernization and innovation projects.”

Simplified Access to a Strategic Alternative for the Public Sector

The award of the TMA lots to Rimini Street under CANUT’s “TMA-SAM-MCO” framework agreement broadens the options available to French public organizations. It enables them to create budgetary and operational flexibility to focus more resources on their strategic priorities, particularly digital sovereignty.

“France’s stated intention to strengthen its digital sovereignty represents a major development for the entire European public sector,” said Martyn Hoogakker, GVP and theatre general manager, EMEA, Rimini Street. “Public institutions must be able to define their technology path according to their needs and priorities, rather than according to commercial timetables imposed by vendors. The framework established with CANUT provides direct and compliant access to a support model enabling CIOs to regain control of their roadmap, optimize their spending and reallocate their resources to strategic initiatives. Present in France since 2017 with a local entity, an office in Paris and dedicated teams, Rimini Street is committed to a long-term approach serving French public-sector organizations.”
