            NOTES TO CONSOLIDATED FINANCIAL STATEMENTS-(Continued)
                                  (Unaudited)

1.   Basis of Presentation

     These consolidated financial statements for the three-month periods ended
     March 31, 1999 and 2000 and the related footnote information are unaudited
     and have been prepared on a basis substantially consistent with the audited
     consolidated financial statements of VIA NET.WORKS, Inc. (VIA) as of and
     for the year ended December 31, 1999, included in VIA's Annual Report on
     Form 10-K as filed with the Securities and Exchange Commission (Annual
     Report). These financial statements should be read in conjunction with the
     audited consolidated financial statements and the related notes thereto
     included in the Annual Report. In the opinion of management, the
     accompanying unaudited financial statements contain all adjustments
     (consisting of normal recurring adjustments) which management considers
     necessary to present fairly the consolidated financial position of VIA at
     March 31, 2000 and the results of operations and cash flows for the
     three-month periods ended March 31, 1999 and 2000. The results of
     operations for the three-month period ended March 31, 2000 may not be
     indicative of the results expected for any succeeding quarter or for the
     year ending December 31, 2000.

     Initial Public Offering

     In February 2000, VIA completed an initial public offering of 17,000,000
     shares of its common stock at $21.00 per share for proceeds of
     approximately $333 million, net of underwriting discounts and commissions
     of approximately $24 million. All outstanding shares of mandatorily
     redeemable convertible preferred stock were converted on a one-for-one
     basis into shares of common stock or shares of non-voting common stock upon
     the closing of the offering.

     Recent Pronouncements

     In June 1998, the Financial Accounting Standards Board issued SFAS No. 133,
     Accounting for Derivative Instruments and Hedging Activities. SFAS No. 133
     establishes a new model for accounting for derivatives and hedging
     activities and supersedes and amends a number of existing standards. SFAS
     No. 133 is effective for fiscal years beginning after June 15, 1999, but
     earlier application is permitted as of the beginning of any fiscal quarter
     subsequent to June 15, 1998. Upon initial application, all derivatives are
     required to be recognized in the statement of financial position as either
     assets or liabilities and measured at fair value. In addition, all hedging
     relationships must be reassessed and documented pursuant to the provisions
     of SFAS No. 133. Subsequent to the issuance of SFAS No. 133, the Financial
     Accounting Standards Board issued SFAS No. 137, "Accounting for Derivative
     Instruments and Hedging Activities-Deferral of the Effective Date of FASB
     Statement No. 133", which defers the effective date of SFAS No. 133 to
     periods beginning after June 15, 2000. VIA has not committed nor does it
     expect to commit to any derivative instrument transactions, and thus does
     not anticipate that this pronouncement will have a significant effect on
     its results.

     In December 1999 the Securities and Exchange Commission (SEC) issued Staff
     Accounting Bulletin No. 101 and amended by Staff Accounting Bullentin No.
     101A which summarizes certain of the SEC staff's views in applying
     generally accepted accounting principles to revenue recognition in
     financial statements. The Staff Accounting Bulletin is effective for the
     year beginning January 1, 2000. The initial adoption of this guidance is
     not anticipated to have a material impact on VIA's results of operations or
     financial position, however, the guidance may impact the way in which VIA
     will account for future transactions.

3.   Acquisitions of Certain Businesses

     Between June 18, 1998 and March 31, 2000, VIA has acquired 20 Internet
     services providers located in Europe and Latin America, offering services
     that include Internet connectivity, web hosting, e-commerce, Internet
     security and other services, primarily to small and mid-sized businesses.

     Each of the acquisitions has been accounted for using the purchase method
     of accounting and, accordingly, the net assets and results of operations of
     the acquired companies have been included in VIA consolidated financial
     statements since the acquisition dates. The purchase price of the
     acquisitions has been allocated to assets acquired, including intangible
     assets, and liabilities assumed, based on their respective fair values.

     In the first quarter of 2000, VIA acquired the following companies:

</TABLE>


     The allocation of purchase price to the acquired tangible and intangible
     assets of Net4You, DNS and ISAR has not been finalized pending an analysis
     of the amount of tangible and intangible assets and liabilities acquired.
     Currently the entire excess purchase price has been allocated to goodwill.
     The actual purchase accounting adjustments may be revised, and VIA may
     allocate a portion of the purchase price to intangible assets other than
     goodwill.

     The acquisition obligations and advances from related parties represent
     amounts due to current or former managers of acquired businesses.


7.   Contingencies

     From time to time, VIA is subject to claims arising in the ordinary course
     of business. In the opinion of management, no such matter, individually or
     in the aggregate, exists which is expected to have a material effect on the
     results of operations, cash flows or financial position of VIA.

     During 1999, VIA established stock option recharge agreements with certain
     of its subsidiaries located in the United Kingdom, Argentina, Germany,
     Mexico, Portugal, and Spain. Under these agreements, VIA will charge its
     subsidiaries for stock options granted to employees of the subsidiaries. As
     a result of these recharge agreements, the subsidiaries are liable for the
     payment of certain employer payroll taxes and social charges based on the
     difference between the exercisable price and fair market value of the stock
     options granted to international employees. Such payroll taxes become
     payable upon exercise at rates ranging between 11% and 24%, as determined
     by the prevailing tax laws in those jurisdictions. No amounts have been
     accrued for payroll taxes or social charges in the accompanying
     consolidated financial statement for the quarter ended March 31, 2000, as
     no stock options have been exercised under these agreements.


8.   Segment Reporting

     VIA offers Internet connectivity, web hosting, e-commerce, Internet
     security and related services to businesses and consumers in Europe and
     Latin America. Both segments generate Internet-related revenues from leased
     lines, dial-up Internet access, web hosting and design, consulting
     services, and sale of third-party hardware and software.

     Each of these geographic operating segments is considered a reportable
     segment. VIA evaluates the performance of its segments based on revenue and
     earnings before interest, taxes, depreciation and amortization and non-cash
     compensation charges ("EBITDA"). The table below presents information about
     the reported revenue, EBITDA and assets of VIA's segments for the quarter
     ended March 31, 1999 and 2000.

Item. 2. Management's Discussion and Analysis of Financial Condition and Results
of Operation

      The following discussion and analysis should be read in conjunction
with the consolidated financial statements and related notes included in Item 1
of this Form 10-Q. This discussion contains forward-looking statements based on
current expectations, which involve risks and uncertainties. In some cases, you
can identify forward-looking statements by terminology such as "may," "will,"
"should," "expects," "plans," "anticipates," "could," "believes," "estimates,"
"predicts," "potential," or "continue," or the negative of these terms or other
similar words. Actual results and the timing of certain events could differ
materially from the forward-looking statements as a result of a number of
factors including referred to in the "Risk Factors" section of VIA's Annual
Report on Form 10-K for the year ended December 31, 1999.

Overview

      We are a leading international provider of Internet access and services
focused on small and mid-sized businesses in Europe and Latin America. We have
built our business through the acquisition, integration and growth of 20
Internet services providers in 12 countries, all of which have been acquired
since June 1998. We currently operate in Argentina, Austria, Brazil, France,
Germany, Ireland, Mexico, the Netherlands, Portugal, Spain, Switzerland and the
United Kingdom.


RECENT BUSINESS ACQUISITIONS

      On January 4, 2000, we acquired 57.5% of the outstanding capital of
Net You, an Internet services provider headquartered in Klagenfurt, Austria, for
approximately $2.9 million, $210,000 of which is payable 12 months following
this acquisition. Between 12 and 36 months from the date of closing, we have the
right to purchase the remaining interest held by the shareholders of Net4You.
The exercise price for this option is determined based on annualized revenues
for the six months preceding the date of exercise and is payable in cash or
shares of our common stock at the election of the Net4You shareholders. If we do
not exercise our call right by the end of this period, the Net4You shareholders
may require us to sell our 57.5% interest in Net4You to them. We also have a
right of first refusal pursuant to which the shareholders must offer to sell
their shares to us if they receive an offer from a third party to purchase their
shares.

      On January 7, 2000, we acquired 100% of DNS Telecom, a provider of
integrated telecommunications services and solutions located just outside of
Paris, France. We issued a promissory note in the amount of approximately
$986,000, issued 112,500 shares of our common stock valued at $16.00 per share
and, upon closing of our initial public offering, paid $8.5 million in cash to
the sellers of DNS Telecom.

      On January 13, 2000, we entered into an agreement to acquire 100% of ISAR,
an Internet services provider located in Munich, Germany, for $8.5 million, in
cash. This transaction was completed on February 16, 2000. We may be obligated
to pay additional consideration of up to approximately $3.7 million depending
upon ISAR's operating results for the year ending December 31, 2000.

      On April 3, 2000 VIA acquired 100% of Internet Access Eindhoven (IAE), a
business-focused Internet services provider located in the Netherlands, for
approximately $7.5 million in cash.

RESULTS OF OPERATIONS

Three months ended March 31, 2000 compared with the three months ended March 31,
1999

     Revenue. We generate revenue primarily from the sale of Internet access
services, both dial-up and dedicated, and Internet value added services.
Internet value added services consist of web-hosting, applications hosting and
related maintenance, domain name registration, sales of hardware and third-party
software, installation, training and consulting and other services. Revenue for
the three months ended March 31, 2000 increased by 344.0% to $20.0 million as
compared to $4.5 million for the three months ended March 31, 1999. This revenue
was generated by the 20 consolidated subsidiaries that we owned for all or a
portion of the first quarter of 2000, as compared to the five consolidated
subsidiaries that we owned for all or a portion of the first quarter of the
preceding year. Additionally, the increase in revenue reflects the change in our
revenue mix from the prior year. In the first quarter of 1999, 79.9% of our
total revenue related to access services, whereas in 2000, 62.7% of total
revenue related to access services, as we attempt to upgrade our customers from
entry-level Internet access to more sophisticated and higher margin products and
services, like web-hosting, virtual private networks and e-commerce solutions.
For the first quarter 2000, 32.9% of total revenue was generated from
web-related services, including web hosting, web design and domain name
registration.

     Internet services operating costs. Internet services operating costs are
the costs we incur to carry customer traffic over the Internet. These costs
increased by 365.8% to $10.4 million for the three months ended March 31, 2000,
as compared to $2.2 million for the corresponding period in the preceding year.
We incurred these costs primarily to lease lines, purchase transit for the local
networks and compensate customer care personnel maintained by the 20
consolidated subsidiaries that we owned for all or a portion of the period.
Additionally, we incurred operating costs associated with our international
network, which we established in June 1999.

     Selling, general and administrative. Selling, general and administrative
are primarily compensation and occupancy costs and the costs associated with
marketing our products and services. We incurred selling, general and
administrative expense of $17.4 million for the three months ended March 31,
2000, a 339.0% increase over the $4.0 million we incurred for the three months
ended March 31, 1999. A portion of the increase relates to the increase in
corporate expenses, which increased by 308.0% from $1.3 million for the first
quarter 1999 to $5.4 million for the first quarter 2000. Non-cash compensation
expense, which was $0 and $1.6 million for the first quarters 1999 and 2000,
respectively, accounted for a portion of this increase. Corporate expenses also
increased as a result of obtaining additional insurance coverage, hiring new
corporate staff and incurring incremental legal and accounting fees related to
VIA's initial public offering. The remaining increase was generated by the 20
consolidated subsidiaries that we owned for all or a portion of the first
quarter of 2000, as compared to the five consolidated subsidiaries that we owned
for all or a portion of the first quarter of the preceding year.

     Depreciation and amortization. Our depreciation and amortization expense
was $9.5 million for the first quarter of 2000, up from $1.9 million from the
first quarter of 1999. This increase was primarily due to the amortization of
goodwill and other intangibles arising from the acquisitions of the 15
consolidated subsidiaries completed between April 1, 1999 and March 31, 2000.
The acquisition of these subsidiaries and the implementation of our
international network also increased our depreciation expense for
telecommunications equipment, computers and other fixed assets. For the 2000
period, $7.4 million, or 78.5% of our depreciation and amortization expense
related to the amortization of goodwill and other intangibles and $2.1 million

                                       12
<PAGE>

or 21.5% was related to the depreciation of fixed assets. For the 1999 period,
$1.4 million or 77.5% of our depreciation and amortization expense related to
the amortization of goodwill and other intangibles and $421,000 or 22.5% was
related to the depreciation of fixed assets.

     Interest income and expense. For the three months ended March 31, 2000, we
earned $2.0 million in interest income and recognized $445,000 in interest
expense. For the same period in the preceding year, we earned $390,000 in
interest income and recognized $276,000 in interest expense.

     Interest in unconsolidated subsidiary. For the three months ended March 31,
1999, we recognized a $194,000 loss related to our minority investment in i-way
Limited (i-way), an Internet services provider located in the United Kingdom. We
originally acquired a 36% interest in i-way in June 1998. In June 1999, we
negotiated the purchase of the remaining 64% equity interest in i-way for total
consideration of $13.1 million, including cash and shares of VIA's common stock.
We have not acquired an equity interest in any other affiliates and therefore
did not recognize any losses related to investments in unconsolidated
subsidiaries for the three months ended March 31, 2000.

     Foreign currency gains and losses. We recognized a $1.5 million loss for
the three months ended March 31, 2000, as compared to a $1.4 million gain for
the corresponding period in the preceding year. The current period loss is
primarily due to the impact of the fluctuation in the value of the Euro on our
Euro denominated cash accounts.

Liquidity and Capital Resources

     Since inception, we have financed our operations primarily through the sale
of equity securities. We raised approximately $181.0 million, in the aggregate,
through three private preferred stock offerings between August 1997 and April
1999, and raised an additional approximately $333 million, net of underwriting
discounts and commissions, through our initial public offering in February 2000.
At March 31, 2000, we had cash and cash equivalents of $332.9 million, including
$15.0 million in restricted cash.

     Immediately subsequent to our initial public offering, we used $8.5 million
to complete the acquisition of ISAR, a German Internet services provider.
Additionally, we paid $10.4 million and issued 316,994 shares of our common
stock to repay notes we had issued to the sellers of U-Net, VIA NET.WORKS
Portugal, formerly known as Esoterica, VIA NET.WORKS Spain, also known as
Interbook, and DNS, and to acquire the remaining minority interest in Dialdata.

     Net cash used in operating activities was $3.1 million for the three months
ended March 31, 2000 and $3.2 million for the three months ended March 31, 1999.
In each period, cash was primarily used to fund operating losses.

     Net cash used in investing activities was $32.1 million for the three
months ended March 31, 2000 and $10.6 million for the same period in 1999. In
each period, cash was primarily used for acquisitions, including bART in the
first quarter of 1999 and Net4You, DNS and ISAR in the first quarter of 2000.

     Net cash provided by financing activities was $332.2 million for the three
months ended March 31, 2000 and $436,000 for the same period in 1999. In each
period, cash was primarily generated by the sale of equity securities, including
in our initial public offering in February 2000.

     In conjunction with our acquisition of VIA NET.WORKS Mexico in October
1999, we have agreed to pay additional purchase price consideration of up to
$30.0 million based on that company's revenue growth between the time of
acquisition and December 31, 2000. Based on the formula, for the fourth quarter
of 1999, we paid $374,000 as additional purchase price. We have restricted cash
of $15.0

                                       13
<PAGE>

million to secure the payment of any additional earned purchase price. We are
entitled to reduce the restricted cash as payments are made.

We continue to pursue an aggressive internal growth and acquisition strategy
that we anticipate will require significant additional funding before becoming
self-sustaining. Additionally, as a result of our acquisitions, we will continue
to amortize substantial amounts of goodwill and other intangible assets. As we
grow, we expect that the amount of goodwill and other intangibles we will
amortize in connection with our investments will represent an increasingly
smaller portion of our expenses. Therefore, we expect to continue to incur net
losses until that point in time when the goodwill and other intangibles we
amortize represents a sufficiently small amount of our expenses that it is
exceeded by our net income before amortization. Exactly when that point in time
may occur depends on the nature, size and timing of future acquisitions and
future amounts of net income before amortization, which we cannot predict.

Foreign Currency Exchange Risks

     We conduct business in 14 different currencies, including the Euro and the
U.S. dollar. With the exception of the Argentine Peso, the value of these
currencies fluctuates in relation to the U.S. dollar. At the end of each
reporting period, the revenues and expenses of our operating companies are
translated into U.S. dollars using the average exchange rate for that period,
and their assets and liabilities are translated into U.S. dollars using the
exchange rate in effect at the end of that period. Fluctuations in these
exchange rates impact our financial condition, revenues and results of
operations, as reported in U.S. dollars.

     Exchange rates can vary significantly. During the first quarter 2000, we
experienced similar exchange rate fluctuations in all eight of the Euro-linked
currencies we deal in. The Euro-linked currencies varied by approximately 9.0%
in relation to the U.S. dollar during the quarter, and ended the quarter
approximately 4.6% below where they were at the beginning of the year. We
realized a foreign currency loss of $1.5 million due to the impact of the
fluctuation in the value of the Euro on our Euro denominated cash accounts in
the first quarter 2000. Future changes in the value of the Euro could have a
material impact on our financial position and results of operations. We also
experienced fluctuations in other exchange rates but they did not have a
material impact on our results.

     Our local operations collect revenues and pay expenses in their home
currencies. They do not have significant assets, liabilities or other accounts
denominated in currencies other than their home currency, and therefore are not
subject to exchange rate risk with respect to their normal operations. On a
consolidated basis, we are subject to exchange rate risks because we translate
our local operations' financial data into U.S. dollars.


Conversion to the Euro

     On January 1, 1999, 11 of the 15 European Union member countries adopted
the Euro as their common legal currency, at which time their respective
individual currencies became fixed at a rate of exchange to the Euro, and the
Euro became a currency in its own right. Presently, the following 11 currencies
are subject to the Euro conversion: the Austrian Schilling, the Belgian Franc,
the Dutch Guilder, the Finnish Markka, the French Franc, the German Mark, the
Irish Punt, the Italian Lire, the Luxembourg Franc, the Portuguese Escudo and
the Spanish Peseta.

     During a January 1, 1999 through January 1, 2002 transition period, the
Euro will exist in electronic form only and the participating countries'
individual currencies will continue in tangible form as legal tender in fixed

                                       14
<PAGE>

denominations of the Euro. During the transition period, we must manage
transactions with our customers and our third-party vendors in both the Euro and
the participating countries' respective individual currencies. We have purchased
and specified our business support systems, including accounting and billing, to
accommodate Euro transactions and dual currency operations during the transition
period. In addition, we intend to require all vendors supplying third-party
software to us to warrant that their software will be Euro compliant. Because
our acquired European companies generally have short operating histories, most
of their systems were acquired and implemented after the Euro was already
contemplated. Consequently, any expenditures related to Euro compliance have
largely been, and will be, in the normal course of business.

     We conduct business transactions with customers, network suppliers, banks
and other businesses, and we will be exposed to Euro conversion problems in
these third-party systems. During the transition period, to the extent we are
supplying local service, we can continue billings and collections in the
individual currencies to avoid Euro conversion problems. However, to the extent
we have cross-border transactions in European Union countries, we will be
exposed to Euro-related risks. The establishment of the European Monetary Union
may have a significant effect on the economies of the participant countries.
While we believe that the introduction of the Euro will eliminate exchange rate
risks in respect of the currencies of those member states that have adopted the
Euro, there can be no assurance as to the relative strength of the Euro against
other currencies. Since a substantial portion of our net sales will be
denominated in the Euro or currencies of European Union countries, we will be
exposed to that risk.


Recent Pronouncements

In June 1998, the Financial Accounting Standards Board issued SFAS No. 133,
Accounting for Derivative Instruments and Hedging Activities. SFAS No. 133
establishes a new model for accounting for derivatives and hedging activities
and supersedes and amends a number of existing standards. SFAS No. 133 is
effective for fiscal years beginning after June 15, 1999, but earlier
application is permitted as of the beginning of any fiscal quarter subsequent to
June 15, 1998. Upon initial application, all derivatives are required to be
recognized in the statement of financial position as either assets or
liabilities and measured at fair value. In addition, all hedging relationships
must be reassessed and documented pursuant to the provisions of SFAS No. 133.
Subsequent to the issuance of SFAS No. 133, the Financial Accounting Standards
Board issued SFAS No. 137, "Accounting for Derivative Instruments and Hedging
Activities-Deferral of the Effective Date of FASB Statement No. 133", which
defers the effective date of SFAS No. 133 to periods beginning after June 15,
2000. VIA has not committed nor does it expect to commit to any derivative
instrument transactions, and thus does not anticipate that this pronouncement
will have a significant effect on its results.

In December 1999 the Securities and Exchange Commission (SEC) issued Staff
Accounting Bulletin No. 101 and amended by Staff Accounting Bullentin No. 101A
which summarizes certain of the SEC staff's views in applying generally accepted
accounting principles to revenue recognition in financial statements. The Staff
Accounting Bulletin is effective for the year beginning January 1, 2000. The
initial adoption of this guidance is not anticipated to have a material impact
on VIA's results of operations or financial position, however, the guidance may
impact the way in which VIA will account for future transactions.

Item 3. Quantitative and Qualitative Disclosures About Market Risk

     The following discussion relates to our exposure to market risk,
related to changes in interest rates and changes in foreign exchange rates. This
discussion contains forward-looking statements that are subject to risks and
uncertainties. Actual results could differ materially due to a number of
factors, as set forth in the "Risk Factors" section of VIA's Annual Report on
Form 10-K for the year ended December 31, 1999.

     VIA has limited exposure to financial market risks, including changes
in interest rates. At March 31, 2000, VIA's financial instruments consisted of
short-term investments and fixed rate debt related to acquisitions and network
purchases. Our investments are generally fixed rate short-term investment grade
and government securities denominated in U.S. dollars. At March 31, 2000 all of
our investments are due to mature within twelve months and the carrying value of
such investments approximates fair value. The majority of our debt obligations
have fixed rates of interest.

VIA is exposed to foreign exchange rate risk primarily due to its obligations
denominated in foreign currencies. These obligations are a result of acquiring
operating companies in various European and Latin American countries. VIA is
also subject to risk from changes in foreign exchange rates for its
international operations which use a foreign currency as their functional
currency and are translated into U.S. Dollars. These risks cannot be reduced
through hedging arrangements.

Use of Initial Public Offering Proceeds

     In February 2000, VIA completed its initial public offering of shares of
common stock, par value $.001 per share. VIA's initial public offering was made
pursuant to a prospectus dated February 11, 2000, which was filed with the SEC
as part of a registration statement, file no. 333-91615, that was declared
effective by the SEC on February 10, 2000. The net offering proceeds to VIA
after deducting underwriting discounts and commissions was approximately $333.0
million.

     Between December 31, 1999 and February 11, 2000, VIA incurred a total of
approximately $656,000 in expenses in connection with its initial public
offering, excluding underwriting discounts and commissions. Of this amount,
approximately $375,000 consisted of expenses paid to or for the underwriters,
leaving a balance of $281,000 in other expenses.

     Between February 11, 2000 and March 31, 2000, VIA has used $18.9 million of
the net proceeds of its initial public offering as follows:
