“We continued to generate strong sales momentum during the third quarter, particularly among our enterprise relationships, positioning the Company very favorably for strong organic growth in 2009 and beyond,” stated Steven E. Zuccarini, Chief Executive Officer of InnerWorkings. “While we realized many achievements during the period, InnerWorkings is not immune to the current macroeconomic environment. Beginning in September and intensifying in October, we have experienced new increased pressure on marketing and advertising budgets, particularly among our clients in the financial, retail, housing and pharmaceutical industries.”

• In the second quarter of 2008, the Company authorized a share repurchase program to buy back up to $50 million of its outstanding shares through December 31, 2009. Since the inception of the program, the Company has purchased approximately 2.2 million shares of its common stock for $26.2 million at an average price of $11.82 per share.

• During the third quarter of 2008, the Company made additional borrowings under our existing credit facilities bringing our total debt to $35.5 million with a total net debt of $3.0 million as of September 30, 2008. The Company has $72.2 million of available liquidity.

“Our success as a high-service, low cost provider continues to reap long-term benefits and we firmly believe that InnerWorkings is on track to become a global multi-billion dollar business,” stated Eric D. Belcher, President and Chief Operating Officer of InnerWorkings.

Outlook

The Company is adjusting near-term 2008 revenue guidance to a range of $435 million to $450 million. Annual earnings per share guidance has been revised to a range of $0.41 to $0.43. Operating earnings per share results are now estimated to range from $0.09 to $0.11 for the fourth quarter of 2008, which reflect the macroeconomic environment.

“We are taking the actions necessary to successfully navigate through this period of economic uncertainty,” stated Joseph M. Busky, Chief Financial Officer of InnerWorkings. “Despite the weak economy, we are actively taking advantage of the opportunities presented and remain very positive about the business in 2009 and beyond. Even with the revised 2008 guidance, we expect to finish with an annual revenue run-rate in excess of $500 million as we enter 2009. Additionally, we expect strong organic growth and to continue to make selective acquisitions throughout 2009.”

Details regarding 2009 guidance will be provided during the Company’s Investor Day scheduled for November 20, 2008 in New York City.
