CDI Corp. Announces Strategic Plan to Enhance Long-Term Growth

Company reorganizing to support new global and growth-focused Engineering and Technology Solutions and Professional Staffing vision; organic revenues expected to reach $1.3 to $1.4 billion by 2014 with operating profit margins of 3.5% to 4.5%

Company anticipates restructuring charge in a range of $8 to $9 million in the fourth quarter of 2011; significant savings will fund targeted investments and improve earnings beginning in 2012

Philadelphia (December 8, 2011) — CDI Corp. (NYSE:CDI) (the “Company”) today announced business model and organization changes aligned with a new growth vision to make CDI an engineering and technology solutions company with global capabilities in select markets. These changes will grow CDI’s solutions business, optimize the Company’s professional staffing operations, and prioritize the geographic markets and industries to which the Company will deliver engineering and technology solutions.

“This strategic plan will focus CDI on high-potential growth opportunities in a limited number of priority industries; selectively expand our geographic footprint to meet the global needs of core clients, and provide a clear vision and improved organizational structure to make CDI a market-leading engineering and technology solutions provider,” said Paulett Eberhart, CDI’s president and chief executive officer. “While this process will be evolutionary, it will drive real change, laying a strong foundation for future growth that allows us to deliver higher-value solutions to our clients and improved returns to our shareholders.”

CDI currently provides solutions for clients in more than 20 industries. While the Company expects to continue serving clients in a variety of business segments, going forward CDI will focus on providing end-to-end engineering and technology solutions primarily for the oil & gas, chemicals, aerospace, industrial products and hi-tech industries. The Company will also leverage its strong staffing capabilities into a global professional services operation that provides cross-industry, in-demand skills in the engineering and technology markets that best serve its clients.

Key elements of the strategic plan include:

Financial Overview

The strategic plan will result in a reduction in staff headcount of approximately 200 employees.

CDI anticipates that this program will result in a pre-tax restructuring charge of approximately $8 to $9 million in the fourth quarter of 2011 reflecting employee severance and related costs.

As a result, CDI anticipates pre-tax cost savings of approximately $22 million in 2012. In order to accelerate growth and support the new organizational structure, CDI is planning to make select employee hires in 2012 which will cost approximately $3.5 million. The Company is also planning additional investments in 2012 to support the new strategic plan, including technology upgrades and restoration of certain employee benefits that were reduced during the financial crisis. Taking into account these investments, CDI expects that at least one-half of the net savings of approximately $18.5 million will benefit pre-tax earnings in 2012.

Business Segment Reporting

“This strategic plan will make CDI more focused and better aligned with current and future client needs while optimizing our service delivery organization for maximum efficiency and operational excellence,” noted Eberhart. Beginning in 2012, the Company will report revenue, gross profit and operating profit geographically. Additionally, the Company will report revenue and gross profit by service lines. MRI, the Company’s franchise delivery model focusing on mid-level and senior-level permanent placement recruitment and staffing, will continue to be reported as a separate business segment and will report revenue, gross profit and operating profit.
