• Retained $82.8 million of cash and no material debt at June 30, 2003

• Sold loss-making Italian operation in order to maintain focus on those countries where VIA has significant operations and growth potential

Amsterdam, The Netherlands (August 15, 2003) — VIA NET.WORKS, Inc. (Nasdaq and EASE: VNWI) today reported results for the quarter ended June 30, 2003. VIA also confirmed that it remains on target for achieving net cash flow break-even during the course of 2004.

Chief Executive Officer Rhett Williams commented, “VIA continues to make progress in seeking to achieve net cash flow break-even during 2004. As expected, we have experienced turbulence in our revenue trend as a result of the actions we have taken

(1) VIA sold its operations in Brazil and Mexico during the second and third quarters of 2002 respectively. These dispositions were structured in such a way that they were not accounted for as discontinued operations and therefore their partial year results continue to be reported in our consolidated results of operations for 2002. As VIA will not consolidate any future results from the Brazilian and Mexican operations, management believes it is more meaningful to analyze trends on the results after excluding the results of Brazil and Mexico from the comparative period ended June 30, 2002. All references in the subsequent discussion that refer to “adjusted continuing operations” exclude the results of the Brazilian and Mexican operations. A reconciliation of such adjusted continuing measures to reported measures is provided in Appendix 1 to this release.

to deliver medium-term growth, yet we continue to drive for further operational improvements through our strategic outsourcing initiatives. We have not shied away from making the difficult decisions needed to keep us focused on a path to profitability. We have brought new products to the market, new disciplines to our organization and new platforms to our back-office. These, combined with a strong customer-focused culture, are helping us fulfill the objectives we set out in the strategic plan. The road to profitability is bumpy, especially when you’re moving as quickly as we are, but we remain on track to reach our key objectives.”

VIA continues to execute on its 2003-2005 Strategic Plan and take actions that contribute both to increased operational performance and future revenue growth.

On the side of improving operational performance, VIA has re-aligned the management organization of VIA along functional lines, and has begun the process of standardizing across all of our operations a common set of systems, processes and controls. During this quarter, the Company:

• Completed a strategic arrangement with Dimension Data Holdings plc for the outsourcing of VIA’s network management and monitoring infrastructure. The transition to Dimension Data’s network management is expected to be completed by the end of 2003. Upon completion, this arrangement will provide VIA with significantly better network management capabilities, scope and scale.

• Acquired new billing and customer management software from Inovaware Corporation, a leading provider of billing and customer management systems, with a target of transitioning all VIA operations to the new system by the first quarter 2004.

• Introduced a state-of-the-art hosting platform based on Sphera Corporation’s Hosting Business Suite for our hosting customers in the US with plans to roll the platform out in other operations. This platform provides VIA with a more robust and scaleable platform for shared hosting customers and resellers.

• Continued personnel reductions, reducing total headcount to 480 as compared to 539 at the beginning of the quarter, and as compared to 575 at the start of the year.

On the side of revenue growth, VIA continues to position itself for solid future growth opportunities through improving the quality of the Company’s sales force, rationalizing its existing product portfolio and introducing new products, and making better use of and refocusing the direct and indirect sales channels. During the quarter, the Company:

• Introduced a resale voice product in the Netherlands with plans to expand the offering to other key markets. This new product enables VIA to offer a more complete solution for our customers’ communication needs.

• Continued to focus sales and marketing teams on specific industry segments. For example, we began to see positive early results from bundled product sales to major retail chains.

• Introduced a targeted customer churn reduction program led by senior management.

Since the end of the quarter, VIA has continued its efforts through the following:

• The sale of the Company’s loss-making Italian operation in order to maintain focus on those countries where VIA has significant operations and growth potential

• Completed a significant outsourcing arrangement with Accenture LLP under which VIA will use Accenture’s financial shared service center to perform back-office transaction processing and certain other finance and administrative functions. The transition of functions should be completed within the first quarter of 2004. VIA expects that the centralization and outsourcing of these functions will significantly improve the internal financial information flows and the efficiency and scalability of the Company’s finance operations. Moreover, together with the new billing and customer care system, the implementation of the financial shared service center will provide VIA’s management with greater visibility of its operations.

These efforts will drive the Company’s performance toward achieving the goals of its Strategic Plan and will also provide VIA with a stable and scaleable platform on which it can pursue significant growth opportunities in the future.

Adjusted Continuing Revenue for the three months ended June 30, 2003 was $16.6 million as compared to $16.4 million for the three months ended June 30, 2002 and $17.8 million for the three months ended March 31, 2003. This 6% decrease compared with the first quarter of 2003 can be attributed in part to the actions taken in implementing the 2003-2005 Strategic Plan. VIA has replaced approximately one third of its sales professionals and approximately 50% of its country sales managers during the half year ended June 30, 2003. We have continued to rationalize our product portfolio, and seek to optimize our sales channels through the recruitment of resellers and other value-added partners. We have taken actions, targeted to reduce the levels of undesired customer churn that we have experienced historically. We expect to begin to see the positive results of these actions in the medium term future.

Adjusted continuing revenue for the first half of 2003 was $34.4 million, a 12% improvement over the same period in 2002. Excluding the impact of foreign exchange movements, adjusted continuing revenue for the six months ended June 30, 2003 reduced by 5% when compared with the six months ended June 30, 2002.

Adjusted Continuing Operating Costs for Internet services were ($7.8 million) or 47% of adjusted continuing revenues for the three months ended June 30, 2003 as compared to ($9.0 million) or 55% of adjusted continuing revenues for the three months ended June 30, 2002 and ($8.5 million) or 48% of adjusted continuing revenues for the quarter ended March 31, 2003.

This improvement is primarily due to continued success we have had in reducing network access costs with key vendors. Adjusted continuing operating costs for Internet services for the three months ended June 30, 2003 benefited from the release of telecommunication cost accruals in respect of disputed charges and line cancellation credits of $0.6 million.

Adjusted continuing operating cost for Internet services was ($16.3 million) or 48% of adjusted continuing revenue for the six months ended June 30, 2003, compared with ($17.6 million) or 57% of adjusted continuing revenue for the six months ended June 30, 2002. Excluding the impact of foreign exchange movements, adjusted continuing operating costs for Internet services reduced by 20% for the six months ended June 30, 2003 compared with the six months ended June 30, 2002.

Adjusted Continuing Selling, General and Administrative Expense (SG&A) was ($15.7 million) for the quarter ended June 30, 2003 as compared with ($15.8 million) for the quarter ended June 30, 2002 and ($14.7 million) for the quarter ended March 31, 2003. Bad debt expense was ($0.4 million) in the 2^nd quarter of 2003 compared with a bad debt benefit of $1.1 million in the same period in 2002, and an expense of ($0.2 million) in the quarter ended March 31, 2003.

Adjusted continuing SG&A was ($30.4 million) for the half year ended June 30, 2003 an 8% reduction when compared with ($33.2 million) for the half year ended June 30, 2002. Excluding the impact of foreign exchange movements, adjusted continuing SG&A expense reduced by 15% compared with the six months ended June 30, 2002.

The decrease in adjusted continuing SG&A for the half year ended June 30, 2003 as compared to the same period in 2002 has been achieved in spite of a bad debt expense of ($0.6 million) in the half year ended June 30, 2003 compared with a bad debt benefit of $1.9 million in the same period in 2002.

Operating Loss From Continuing Operations was ($10.1 million) for the quarter ended June 30, 2003 an 18% improvement compared with ($12.4 million) for the quarter ended June 30, 2002 and a 21% decline compared with ($8.4 million) for the quarter ended March 31, 2003.

Operating loss from continuing operations was ($18.5 million) for the half year ended June 30, 2003, compared with ($28.4 million) for the half year ended June 30, 2002.

Net Loss From Continuing Operations was ($5.2 million) for the quarter ended June 30, 2003 as compared with ($0.8 million) for the quarter ended June 30, 2002 and with ($5.4 million) for the quarter ended March 31, 2003. The net loss from continuing operations includes net foreign currency gains of $4.7 million and $11.0 million for the 2^nd quarter of 2003 and 2002, respectively.

Net loss from continuing operations of ($10.7 million) for the half year ended June 30, 2003 represents a significant improvement as compared with ($19.0 million) for the half year ended June 30, 2002.

Cash and Cash Equivalents held by VIA as of June 30, 2003 were $82.8 million and restricted cash as of June 30, 2003 was $940,000. The change in cash during the three months ended June 30, 2003, defined as the net decrease in cash and cash equivalents, was ($8.3 million) compared to ($8.7 million) in the three months ended June 30, 2002 and compared to ($6.7 million) in the three months ended March 31, 2003. Excluding the impact of foreign exchange gains and monies expended in the repurchase of VIA treasury stock, the change in cash and cash equivalents for the three months ended June 30, 2003 was ($8.1 million), compared to ($11.2 million) in the three months ended June 30, 2002 and compared to ($7.5 million) in the three months ended March 31, 2003. VIA spent ($0.8 million) on the repurchase of VIA treasury stock in the second quarter of 2003, compared with $nil in the second quarter of 2002 and $nil in the first quarter of 2003.

The change in cash during the six months ended June 30, 2003 was ($15.0 million) compared to ($24.7 million) for the six months ended June 30, 2002.

2003 - 2004 Outlook: Despite the challenges of pursuing revenue growth while making significant operational improvements, VIA continues to expect that net cash flow (defined as the movement in cash and cash equivalents) will reach the break-even point during the course of 2004. In addition, the Company has previously provided guidance of delivering revenues of $70 - $75 million for the full year 2003. Management continues to expect that VIA’s full year revenue will be within that range, although most likely at the lower end of the range, assuming no significant adverse movements in foreign currency exchange rates, particularly the Euro to US Dollar exchange rate. The Company also expects to further reduce reported losses from continuing operations, as well as the cash used in operating activities. The Company believes that its available cash will be sufficient to fund expenditures under the Strategic Plan and its working capital and capital expenditure requirements until it achieves positive net cash flow, at which time VIA expects to have substantial cash reserves remaining.

All references in the preceding discussion that refer to “adjusted continuing operations” exclude the results of the Brazilian and Mexican operations.
