Sonata Software Ltd.

Sonata Software has informed that following the Proclamation issued by the Government of the United States on September 19, 2025, and the accompanying Memorandum dated September 20, 2025, introducing a one-time fee of US$100,000 per new H-1B petition, Sonata Software has reviewed the potential implications on its financials and operations. Their assessment is as follows: Minimal Business Impact: H-1B visa utilization within Sonata Software is not material. Existing deployed H-1B employees and contractors remain unaffected; Service Continuity Assured: The Company’s sustained investments in workforce planning, visa compliance, global mobility, and local hiring ensure uninterrupted client service. Further, Sonata’s strategic focus on expanding local and nearshore delivery centers continues to strengthen resilience in its global delivery model and aligns with its Modernization Engineering value proposition. The Company is closely monitoring regulatory developments and will provide timely updates should there be any changes requiring client or stakeholder attention. This intimation is also available on the Company’s website at www.sonata-software.com.
