FAIRFAX, Va. -- ICF International, Inc. (Nasdaq:ICFI), a leading provider of consulting services and technology solutions to government and commercial clients, reported revenue and earnings growth for the third quarter ended September 30, 2006.

Third-Quarter Results

Revenue for the period was US$107.8 million, an increase of 156 percent from the $42.2 million reported for last year's third quarter. This year's third-quarter revenue performance included $55 million representing the first contribution from the Company's recently-awarded Housing Program Management Services contract to help restore Louisiana's housing infrastructure. The three-year program has a total contract value of $756 million.

Earnings from operations for the period were $6.3 million, which included a nonrecurring charge of $2.7 million for one-time bonus payments and $0.3 million in noncash compensation expenses as required under FAS 123R. This was a 271 percent increase from the 2005 third quarter, when the Company had earnings from operations of $1.7 million. The one-time bonus was negotiated under an incentive plan that has been in place since 1999 and was triggered by the completion of the Company's initial public offering (IPO).

Net income for the quarter increased to $3.0 million, or $0.28 per diluted share, from the $1.2 million, or $0.13 per diluted share, earned in the comparable 2005 period, an increase of 138 percent. Pro forma diluted earnings per share, excluding the nonrecurring charge and FAS 123R expense, were $0.44.

On September 28, 2006, ICF Common Stock began trading in the Company's initial public offering of 3,659,448 shares (4,670,000 shares including shares sold by selling stockholders) at a price of $12.00 per share. After full exercise of the underwriters' overallotment option in October to purchase an additional 700,500 shares, aggregate net proceeds to the Company after offering expenses were approximately $46.5 million. The initial public offering, exclusive of the overallotment option, is reflected on ICF's September 30, 2006, balance sheet as a receivable from the underwriters, as the settlement date was subsequent to the close of the reporting period.

Commenting on the results, Sudhakar Kesavan, Chairman and Chief Executive Officer, said, "Our strong third-quarter financial performance reflects growing demand for ICF's combination of advisory and implementation services, and our ability to utilize superior domain expertise to execute key projects for government and commercial clients."

"ICF achieved several significant milestones in the third quarter that should create positive momentum in the periods ahead," Mr. Kesavan noted. Highlights include:

* ICF won recompetitions totaling $147 million during the quarter, representing 98 percent of potential revenue from recompetitions, in addition to winning significant new government and commercial contract awards totaling $51 million during the quarter.

* ICF met the deadlines established for the first phase of the Louisiana Housing Program Management Services Contract.

* ICF successfully completed its IPO. This offering has enabled the Company to retire its term and revolver debt, thereby providing the resources to support continued organic growth and pursue strategic acquisitions.

Nine-Month Results

Revenue for the first nine months of 2006 was $217.4 million, compared to $125.4 million last year, an increase of 73 percent. Earnings from operations were $7.9 million compared to $6.4 million, an increase of 24 percent. Included in earnings from operations for the 2006 nine-month period were nonrecurring charges of $7 million, of which $4.3 million related to a one-time charge for the abandonment of ICF's leased facility in San Francisco, CA, and a portion of its Lexington, MA, facility, as well as a $2.7 million charge related to one-time bonus payments. Also included in earnings from operations for the first nine months of 2006 were noncash compensation expenses totaling $0.6 million, as required by FAS 123R. Net income was $2.7 million, or $0.26 per diluted share, compared to net income of $3.1 million, or $0.32 per diluted share in the comparable period in 2005.

Excluding the FAS 123R expenses and nonrecurring charges noted above, earnings from operations for the 2006 nine months were $15.5 million compared to $6.4 million last year, an increase of 143 percent. Pro forma diluted earnings per share for the nine months were $0.65. A table reconciling pro forma and GAAP earnings from operations is included at the end of this press release.
