State Street Corporation has announced the appointment of new executives to support the next phase of the firm’s growth strategy and its continued focus on driving innovation and transformation to help clients achieve better outcomes in increasingly complex global markets. Specifically, Mostapha Tahiri, previously Chief Operating Officer, will become President of State Street Alpha, assuming responsibility for Alpha, Charles River Development (CRD), and a suite of innovative platform solutions; and Ann Fogarty, previously Chief Operating Officer of Investment Services, has been named Enterprise Chief Operating Officer.
Regarding Tahiri’s appointment, the firm clarifies that Alpha is State Street’s leading end-to-end (front-to-back) integrated platform, combining CRD’s front-office technology with the firm’s servicing, markets, and data capabilities to offer investors a single platform experience across the entire investment lifecycle. Drawing on his deep commercial, client, technological, AI, and operational experience, Tahiri will assume end-to-end responsibility for commercial strategy, product strategy, technology, and client delivery for Alpha and CRD. Leveraging the strength of this platform, Tahiri will focus on accelerating growth, strengthening execution, transforming the operating model, and maximizing the full potential of innovation across the business.
Tahiri will also serve as Chair for Asia-Pacific (APAC). Having spent much of his career serving clients in APAC and following his recent return to Singapore, Tahiri is ideally positioned to oversee State Street’s business relationships in the region with key clients, regulatory bodies, and strategic partners. He will continue to serve on State Street’s Executive Committee. This executive has nearly 30 years of international experience in the asset management, asset servicing, investment platforms, and financial technology sectors. His track record includes leading and transforming complex global businesses and driving initiatives where clients, technology, and operations intersect.
Another announced change affects Ann Fogarty, previously Chief Operating Officer of Investment Services, who has been named Enterprise Chief Operating Officer, succeeding Tahiri. In her new role, she will also report to O’Hanley. As Enterprise Chief Operating Officer, she will lead the firm’s global technology and operations areas and drive State Street’s technological modernization and AI agenda, reflecting the growing convergence of technology, operations, data, resilience, and client service across the industry. She will continue to co-lead the firm’s global transformation program alongside John Woods, Chief Financial Officer (CFO), helping accelerate innovation, build greater scale and efficiency, reduce cycle times, and further strengthen the quality of client outcomes across State Street’s businesses. Fogarty will continue to serve on the firm’s Executive Committee. Fogarty brings nearly four decades of industry experience. She has led key client operations for Investment Services, where she drove operational simplification, resilience, and enterprise-wide global transformation initiatives. Fogarty also chairs the Supervisory Board of State Street Bank International GmbH (SSBI), our principal European bank.
Following these changes, Ron O’Hanley, Chairman and Chief Executive Officer (CEO) of State Street, highlighted: “Our clients face increasingly complex markets and operating environments, and are demanding with increasing frequency that technology and operations function seamlessly together. Mostapha’s focus on Alpha—one of State Street’s most differentiating businesses and a core strategic priority for the firm—and Ann’s leadership in global operations and technology provide dedicated direction in areas that drive how we create value for clients. These appointments reinforce the strength of our leadership team and position us to continue executing for clients while investing in the future of our business.”
Together, these appointments establish dedicated leadership in two key areas critical to client needs and the firm’s long-term strategy. They also reflect State Street’s commitment to leading alongside its clients as technology, AI, data, and operations shape the future of investment and investment infrastructure. Both appointments are effective as of 09/14/2026.
