Interactive Data Reports Third-Quarter 2006 Revenue Increased by 16.7% and Net Income Increased by 15.8%.

Company Also Announces Special Dividend of $0.80 Per Share and New Two Million Share Repurchase Program

BEDFORD, Mass. -- Interactive Data Corporation (NYSE: IDC) today reported its financial results for the third quarter ended September 30, 2006. Interactive Data's third-quarter 2006 revenue grew 16.7% to $156.7 million from $134.2 million in the third quarter of 2005. Net income for the third quarter of 2006 was $26.8 million, or $0.28 per diluted share, which includes $2.0 million of after-tax, stock-based compensation expense associated with the adoption of Financial Accounting Standards Board Statement No. 123(R) (FAS 123R). This represents a 15.8% increase over net income of $23.1 million, or $0.24 per diluted share, in the third quarter of 2005.

"Our third-quarter 2006 results were very strong due to a combination of excellent new sales, lower cancellation levels and careful control on spending," stated Stuart Clark, Interactive Data's president and chief executive officer. "Although the summer months are historically slow for new sales, we enjoyed strong new sales in the third quarter of 2006, particularly at our FT Interactive Data and ComStock businesses, and we also saw eSignal resume its growth. As a result of these performances, we produced organic revenue growth of 5.7% during the third quarter of 2006. Renewal rates for our institutional businesses remained at approximately 95% during the third quarter of 2006. In addition to our solid performance, our third-quarter 2006 net income benefited from a reduction in our estimated effective annual tax rate."

Clark continued, "We were also pleased with the contributions from the businesses we acquired during the past 12 months, Interactive Data Managed Solutions and Quote.com. The integration of both these organizations is progressing steadily, and our Interactive Data Managed Solutions business generated strong new sales in the third quarter. Just as important, our investments in new product development across the organization are resulting in the delivery of new and enhanced offerings."

Commenting on the declaration of a special dividend of $0.80 per share and the authorization for a new stock repurchase program for up to two million shares of common stock, both of which were also announced today, Clark stated, "Our Board determined that it is an appropriate point in time to return over $115 million to shareholders. Using our cash for acquisitions and internal investments that help us strengthen and grow our business is still our preferred use of capital. Moving forward, the Board will continue to evaluate a range of opportunities for using our cash to expand the business and create value for shareholders.

"Looking ahead, we believe that Interactive Data is well positioned for continued success," concluded Clark. "New and impending regulatory requirements in both North America and Europe, combined with the increasing complexity of new investment alternatives, are reinforcing the compelling value that Interactive Data's offerings deliver. In order to effectively bring new services to market and work strategically with our clients, we are driving collaboration across our sales, marketing and product development organizations."

Other Third-quarter and Recent Operating and Financial Highlights

Effects of Foreign Exchange:

* Interactive Data's third-quarter 2006 revenue was positively impacted by $1.4 million due to the effects of foreign exchange. Third-quarter 2006 revenue before the effects of foreign exchange grew by $21.1 million, or 15.7%, over the comparable period in 2005. Total costs and expenses in the third quarter of 2006 were negatively impacted by $1.1 million due to the effects of foreign exchange. Third-quarter 2006 total costs and expenses before the effects of foreign exchange increased by $18.4 million, or 18.9%, over the third quarter of 2005.

Institutional Services Segment:

* FT Interactive Data's third-quarter 2006 revenue of $96.7 million grew 7.4% over the prior year's third quarter (or an increase of 6.3% before the effects of foreign exchange). North American revenue for the third quarter of 2006 increased 5.7% over the third quarter of 2005. Third-quarter 2006 European revenue increased by 14.5% (or increased 9.0% before the effects of foreign exchange) from the third quarter of last year. Growth in both North America and Europe during the quarter primarily reflects increased business with existing customers, particularly for evaluated pricing and related reference data services. FT Interactive Data's Asia-Pacific third-quarter 2006 revenue was essentially flat compared with the prior year's third quarter.

* ComStock generated third-quarter 2006 revenue of $30.5 million, an increase of 60.3% over the same quarter last year (or an increase of 58.5% before the effects of foreign exchange). ComStock's 2006 third-quarter revenue includes $11.2 million from Interactive Data Managed Solutions. Excluding the effects of foreign exchange, the contribution of acquisitions and intercompany eliminations resulting from acquisitions, ComStock's underlying revenue increased by 4.5% primarily due to increased new business with institutions and lower levels of cancellations. During the third quarter, ComStock expanded its market coverage to include additional Level II and additional financial data from Eastern and Central Europe. Earlier this month, ComStock launched PlusTick, a new service that will provide financial institutions with access to high-quality tick and trade data for global securities.

* CMS BondEdge's revenue for the third quarter of 2006 of $8.1 million declined 1.2% from last year's third quarter. CMS BondEdge's third-quarter 2006 revenue decline reflects the impact of cancellations primarily caused by client consolidation activities, which more than offset new sales and increased business with existing customers. CMS BondEdge's third-quarter 2006 performance was highlighted by 11 new client installations and initial sales of the CMS BondEdge fixed income analytical datafeed service, which was launched during the second quarter of 2006.

Active Trader Services Segment:

* eSignal's third-quarter 2006 revenue of $21.5 million increased 26.0% from the same quarter last year (or an increase of 25.6% before the effects of foreign exchange). The increase reflects the $3.1 million contribution of Quote.com, which was acquired during the first quarter of 2006, as well as the continued expansion of eSignal's direct subscriber base. Excluding the contribution from Quote.com and the effects of foreign exchange, eSignal's revenue growth in the third quarter of 2006 was 7.2%. eSignal ended the third quarter of 2006 with nearly 61,600 direct subscription terminals, which includes approximately 12,900 direct subscription terminals for Quote.com-related services. During the third quarter of 2006, eSignal launched the new Quote.com website.

Effective Tax Rate:

* The third-quarter 2006 effective tax rate of 35.5% reflects the reduction in the Company's estimated annual effective tax rate primarily due to a shift in geographic income to lower tax rate jurisdictions in addition to the release of tax reserves that were no longer required as a result of the expiration of a statute of limitations.

Capital Expenditures:

* Approximately $2.7 million, or 27%, of the $9.9 million in third-quarter 2006 capital expenditures were associated with facility relocation activities.

Nine-Month Results:

* For the nine months ended September 30, 2006, Interactive Data reported revenue of $451.3 million versus $406.8 million for the comparable period in 2005, an increase of $44.4 million, or 10.9%. Total costs and expenses rose 15.2%, or $45.5 million, to $344.1 million in the first nine months of 2006. Pre-tax stock-based compensation expense associated with the adoption of FAS 123R during the first nine months of 2006 was $9.9 million. Income from operations for the first nine months of 2006 was $107.2 million, compared with $108.2 million for the same period one year ago. Net income for the first nine months of 2006 was $68.6 million, or $0.72 per diluted share, compared with $69.2 million, or $0.72 per diluted share, in the comparable period of 2005. The tax rate for the first nine months of 2006 was 38.5% compared with 38.0% in the same period last year or 36.9% for the full year 2005.

Cash Position, Stock Buyback Activities and Special Dividend:

* As of September 30, 2006, Interactive Data had no outstanding debt and had cash, cash equivalents and marketable securities of $216.1 million. During the third quarter of 2006, Interactive Data completed its existing June 2005 share buyback program by purchasing 226,600 shares of common stock at an average price of $20.53 per share. The average price for all two million shares of common stock repurchased under the stock buyback program initiated in June 2005 was $21.01 per share. With the completion of this most recent program, Interactive Data's Board of Directors has authorized a new buyback program for the repurchase of up to two million shares of its common stock.

* Repurchases made under the new two million share buyback program will be made in the open market or in privately negotiated transactions from time to time, subject to market conditions and other factors and in compliance with applicable legal requirements. Repurchases of common stock may also be made under a Rule 10b5-1 plan, which would permit shares to be repurchased when Interactive Data might otherwise be precluded from doing so under insider trading laws. Interactive Data intends to use cash on hand to fund any purchases. The Company is not obligated to acquire any particular amount of common stock as a result of the plan, which may be suspended or discontinued at any time.

* Interactive Data also announced today that its Board of Directors has declared a special dividend of $0.80 per share of common stock. The dividend is payable on December 5, 2006 to stockholders of record on November 9, 2006.

* In combination, the special dividend and stock repurchase program would return over $115 million to stockholders (assuming the new buyback program is completed based on the current market value of Interactive Data's common stock).

Board of Directors:

* In early September 2006, as previously announced, Robert C. Lamb, Jr. was appointed to Interactive Data's Board of Directors. Lamb currently serves as chairman of the Board's Audit Committee and serves on the Independent Committee as well as the Nominating and Corporate Governance Committee.

Outlook

We anticipate that market conditions in the fourth quarter of 2006 will be similar to those experienced in recent quarters. We believe that spending on market data and related services by customers in the financial services industry will continue to be influenced by their focus on cost containment initiatives. Based on our results to date and our expectations for the balance of the year, our outlook for 2006 is as follows: We continue to expect that 2006 revenue growth will be in the range of 12-13%. We now expect that the estimated after-tax, stock-based compensation expenses associated with the adoption of FAS 123R will be at the low end of prior guidance for this expense, which ranged from $8.0 million to $10.0 million. We continue to anticipate that 2006 net income will decline slightly versus 2005. Due to a shift in geographic income to lower tax rate jurisdictions in addition to the release of tax reserves that were no longer required as a result of the expiration of a statute of limitations, our effective tax rate for 2006 is now expected to be in the range 38.5% to 39.5%, compared with prior guidance issued in July 2006 for an effective annual rate in the range of 39.5% to 40.5%. We now anticipate that non-GAAP income from operations, which excludes the impact of FAS 123R, will grow in the 8-10% range in 2006 compared with prior guidance issued in July 2006 for non-GAAP income from operations growth in the 7-9% range.

2006 capital expenditures are now expected to be at the low end of original guidance that ranged from $40.0 million to $43.0 million. This includes capital expenditures of approximately $10.0 million to $12.0 million associated with the planned relocation of Interactive Data's corporate headquarters in Bedford, Massachusetts and ComStock's Harrison, New York facility during the year. We expect that approximately 50% of the capital expenditures associated with these facility activities will be reimbursed by the landlords of these facilities by early 2007.

Non-GAAP Information

In an effort to provide investors with additional information regarding our results on a generally accepted accounting principles (GAAP) basis, we also disclose the following non-GAAP information, which management believes provides the following useful information to investors:

* Management refers to growth rates at constant foreign currency exchange rates so that business results can be viewed without the impact of changing foreign currency exchange rates, thereby facilitating period-to-period comparisons of our underlying business. Generally, when the U.S. dollar either strengthens or weakens against other currencies, the growth at constant currency rates will be higher or lower than growth reported at actual exchange rates.

* Management includes information regarding organic revenue growth, which excludes the contribution of businesses acquired or closed during the past 12 months, related intercompany eliminations, the effects of foreign currency exchange rates and the recognition of revenue deferred in prior quarters because management believes that facilitating period-to-period comparisons of our organic revenue growth on a constant dollar basis better reflects actual trends. As part of determining organic growth, management refers to revenue for our FT Interactive Data, ComStock, CMS BondEdge, and eSignal businesses. Management uses such information for evaluating its business, and for forecasting and planning purposes. In addition, since we have historically reported revenue for these businesses to the investment community as part of our reports on Form 10-K and Form 10-Q, we believe that continuing to offer such information provides consistency in our financial reporting.

* Management includes information regarding core total costs and expenses which excludes total costs and expenses associated with businesses acquired or closed during the past 12 months, and the effects of foreign exchange and the recognition of costs and expenses deferred in prior quarters, because management believes changes in our core total costs and expenses on a constant dollar basis better reflect actual trends in the core businesses.

* Management includes information regarding core operating profit, which excludes revenue and costs and expenses associated with acquired or closed businesses during the past 12 months, intercompany eliminations, the effects of foreign exchange and the recognition of revenue and costs and expenses deferred in prior periods because management believes changes in our core operating profit on a constant dollar basis better reflect actual trends in the core businesses.

* Management refers to non-GAAP income from operations, which excludes the estimated impact of the adoption of Financial Accounting Standards Board Statement No. 123(R), "Share-Based Payment," because our historical financial performance did not include this expense. As a result, we believe that continuing to offer such information about our financial performance provides consistency in our financial reporting.

The above measures are non-GAAP financial measures and should not be considered in isolation from (and are not intended to represent an alternative measure of) revenue, total costs and expenses, earnings or cash flows provided by operating activities, each as determined in accordance with GAAP. In addition, the above measures may not be comparable to similarly titled measures reported by other companies.
