Exhibit 99.1 iBasis Reports Record Revenue, Gross Profit, and Traffic Volume in Second Quarter 2006; Company Expands EBITDA Margin, Achieves Sixth Consecutive Quarter of Positive Cash Flow BURLINGTON, Mass.--(BUSINESS WIRE)--July 26, 2006--iBasis, Inc. (NASDAQ: IBAS), the global VoIP company(TM), today announced results for the second quarter ended June 30, 2006. Revenue for the second quarter of 2006 was $127.3 million, compared to $94.6 million for the second quarter of 2005. Net income for the second quarter of 2006 was $0.3 million, or $0.01 per share, compared to net loss for the second quarter of 2005 of $0.8 million, or $(0.03) per share. Net income for Q2 2006 includes $1.5 million in current transaction costs related to our pending merger with KPN Global Carrier Services. Excluding these expenses, net income for the second quarter of 2006 was $1.9 million, or $0.06 per share. iBasis achieved $4.0 million in Adjusted EBITDA for the second quarter of 2006, compared to Adjusted EBITDA of $2.8 million in the second quarter of 2005. Adjusted EBITDA is a non-GAAP measurement presented to provide further information about the Company's operating trends, as explained below. Highlights of the second quarter include: -- Adjusted EBITDA growth of 26% over Q1 2006; -- Sequential growth in revenue of 15% and in gross profit of 14%; -- Sequential growth in minutes of 15% to 2.7 billion; -- Sixth consecutive quarter of positive cash flow; -- Return to the Nasdaq exchange; and -- Agreement to merge KPN Global Carrier Services into iBasis. "This was another very strong quarter across the board," said Ofer Gneezy, president and CEO of iBasis. "We achieved solid growth in revenue and gross profit over the first quarter of 2006 in both our Trading and our Retail businesses. We also achieved a significant sequential increase in minutes carried on The iBasis Network(TM), a result of continuing strong demand for our international VoIP services. "In our Trading business, we added a large number of new customers, including consumer VoIP providers, which accounted for 10% of our Trading revenue in the quarter. We ended the second quarter with more than 40 consumer VoIP provider customers. "In our Retail business, we continued to introduce new cards in the market and effectively manage the product lifecycle, resulting in sequential growth in revenue and gross profit, as well as slight gross margin expansion. "In addition to our strong results we had other good news this quarter. We celebrated our return to the Nasdaq exchange, which followed a successful reverse stock split. The listing better positions us to attract additional large institutional investors and expand the field of major industry analysts that cover iBasis. "Our most exciting news was our agreement to merge KPN Global Carrier Services into iBasis, a development that has the potential to be an industry-changing event. The combination will bring together an established incumbent carrier with a very strong position in the European mobile market and a fast-growing VoIP leader. The result will make iBasis a Tier One player in the international voice market and one of the top carriers of international traffic worldwide, with combined annualized traffic approaching 20 billion minutes. We're very excited, and customers we have spoken to about the merger are enthusiastic about the enhanced capabilities and offerings of the expanded iBasis. We expect the transaction to be completed before the end of this year. "We're very pleased with our Q2 results, and we are confident that iBasis is on the right track to achieve its goals."

This combination will establish iBasis as one of the largest international voice carriers in the world, with combined 2005 revenues exceeding $1.1 billion and more than 15 billion combined minutes in 2005. iBasis will acquire KPN subsidiary KPN Global Carrier Services and receive $55 million in cash from KPN in return for the issuance of approximately 40 million shares of iBasis common stock, which represent a 51 percent ownership interest in iBasis on a diluted basis. iBasis shareholders of record immediately prior to closing will receive a cash dividend of $113 million immediately following closing. In connection with payment of the dividend, outstanding common stock options will be adjusted to preserve their value. The transaction, which is subject to customary closing conditions, including regulatory approvals and the approval of iBasis shareholders, is expected to be completed before the end of 2006. In the second quarter of 2006, we incurred approximately $1.5 million in direct expenses related to this transaction, primarily related to investment banking, legal and accounting fees. We currently expect additional transaction costs of approximately $0.8 million to $1.2 million, most of which we anticipate will be incurred in the third quarter of 2006. FCC Ruling on Prepaid Calling Cards On June 30, 2006, the Federal Communications Commission announced the results of a Notice of Proposed Rulemaking, which would require providers of prepaid calling cards that utilize Internet Protocol to contribute to the Universal Service Fund (USF) and pay other regulatory fees. In connection with its Retail business, the Company plans to absorb or pass along such fees, which based on current traffic mix equal approximately 1.8% of revenue. The FCC ruling would also impose the fees on a retroactive basis, which the Company plans to contest. As of June 30, the Company estimates that the maximum potential retroactive charge would be approximately $2.6 million. If not stayed, the order could become effective during the fourth quarter. Guidance The Company believes that in 2006 on a standalone basis it will: -- achieve revenue in the range of $500 to $520 million; and -- achieve non-GAAP EPS (which excludes merger-related expenses and potential retroactive USF and other regulatory fees) of $0.25 to $0.30. Planned expenditures for 2006 include $10 to $12 million in capital asset investments.
