WiderThan Reports 2006 Second Quarter Results
Second Quarter Revenues Grow to $33.1 Million, an Increase of 49% Year-Over-Year;
New Customer Win in Ringback Tone Service Announced

Seoul, South Korea — August 9, 2006 — WiderThan Co., Ltd. (NASDAQ: WTHN), a leading global provider of integrated mobile entertainment solutions for wireless carriers, today reported financial results for the second quarter ended June 30, 2006 and issued financial guidance for the third quarter and fourth quarter of 2006.

Second quarter 2006 revenues were $33.1 million, an increase of 49% over the $22.2 million in the second quarter of 2005. Net income, calculated in accordance with generally accepted accounting principles in the United States (US GAAP), for the second quarter of 2006 was $4.6 million, or $0.23 per diluted American Depositary Share (ADS), compared to $1.6 million or $0.08 per diluted ADS in the prior year period. Included in net income for the second quarter of 2006 was a non-cash, stock-based compensation charge of $0.7 million, compared to a charge of $0.6 million in the prior year period. Adjusted net income, which excludes non-cash stock compensation expense, was $5.2 million, or $0.26 per diluted ADS, in the second quarter of 2006, compared to an adjusted net income of $2.2 million, or $0.21 per diluted ADS, in the prior year period.

Commenting on the results, Sang Jun Park, WiderThan’s Chief Executive Officer, said, “WiderThan had a strong second quarter in 2006. I am also very pleased to announce that we have signed a new carrier customer for our Ringback Tone (RBT) Service. Service integration for this carrier is underway and we expect to launch service by the end of the third quarter of this year.”

F. Terry Kremian, WiderThan’s Global President, said, “Ringback tone subscribers outside Korea grew 20% sequentially in the second quarter of 2006 from the first quarter of 2006. Overall, we added a total of 1.5 million new RBT users bringing our total active RBT subscribers to 16.9 million.” Mr. Kremian added, “We continue to see solid consumer uptake for our carriers’ services in both ringback tone penetration and music-on-demand services.”

Cash, cash equivalents and short-term financial instruments on June 30, 2006, totaled $93.1 million. During the second quarter of 2006, WiderThan generated approximately $3.0 million in cash from operations. Hoseok Kim, WiderThan’s Chief Financial Officer, commented on the company’s finances saying, “Positive cash flow in the second quarter further enhances our strong balance sheet. In addition, we continue to improve our internal processes related to financial reporting which enables us to report our results in a more timely manner.”

WiderThan is issuing financial guidance for the third quarter and fourth quarter of 2006 based on information as of August 8, 2006. This guidance assumes that our major currency exchange rates remain constant.

Non-GAAP Measures

To supplement WiderThan’s consolidated financial statements presented in accordance with US GAAP, WiderThan uses non-US GAAP measures of certain components of financial performance, including adjusted EBITDA (earnings before interest, taxes, depreciation and amortization) and adjusted net income, which are adjusted from our US GAAP results. These non-GAAP results provide useful information to both management and investors by excluding expenses which we believe may not be indicative of the Company’s core operating results. These measures should be considered in addition to results prepared in accordance with US GAAP, but should not be considered a substitute for, or superior to, US GAAP results. The non-GAAP measures included in this press release have been reconciled to the nearest US GAAP measure.

Adjusted EBITDA excludes non-cash stock-based compensation expense, depreciation and amortization expense from the Company’s statement of operations. Adjusted net income excludes non-cash based stock compensation expense from the Company’s statement of operations.
