Our first president was C. D. Lester, a former Tuskegee Airman, who was joined in the firm by three U.S. Department of Defense analysts. Our consulting business proved more successful than our investments, and in 1972, the firm was reorganized as a consulting firm and renamed ICF Incorporated.
Focusing on energy issues for U.S. federal agencies and for industry throughout the 1970s, the firm expanded into environmental business rapidly in the 1980s and began to build its engineering capabilities. In 1988 ICF acquired Kaiser Engineers, which had originated as the engineering unit of Henry J. Kaiser's industrial empire and grew to rank among the largest engineering and construction companies in the world. In the following year (1989), the combined company went public and eventually traded stock on the New York Stock Exchange. The combined company operated as "ICF Kaiser,"with the consulting unit remaining largely intact.
In 1999, ICF Consulting ended its decade-long affiliation with Kaiser Engineers through a leveraged buyout, financed in part by the CM Equity Partners, LP, an equity investment firm based in New York City.
In 2006, ICF Consulting was renamed ICF International to reflect our growing geographic presence and increased scope of our service offerings from advisory services through implementation and improvement. The firm also pursued an Initial Public Offering (IPO) and now is a publicly traded firm listed on the NASDAQ under the symbol ICFI.
ICF International is a global, diversified firm that combines the entrepreneurship and dynamism of a new company with a solid reputation in the consulting industry derived from more than 40 years of performance.
