ITEM 1. BUSINESS

Overview

PART I

We  are a leading facilities-based provider of low-cost, high-speed Internet access and Internet
Protocol, or IP, communications services. Our network  is specifically designed and optimized  to  transmit
data using IP. We deliver our services  primarily to small and  medium-sized  businesses, communications
service providers and other bandwidth-intensive organizations through approximately 21,300 customer
connections in North America and Europe.

Our primary on-net service is Internet  access at a speed  of  100 Megabits per  second,  much  faster

than typical Internet access currently offered to businesses.  We offer  this  on-net  service  exclusively
through our own facilities, which run all the way  to  our  customers’ premises.  Because of our integrated
network  architecture,  we  are  not  dependent  on  local  telephone  companies  to  serve  these  on-net
customers. Our typical customers in multi-tenant office  buildings are law  firms,  financial  services  firms,
advertising and marketing firms and other  professional  services businesses. We  also provide on-net
Internet access to certain bandwidth-intensive users  such as universities, other ISPs and commercial
content providers at speeds of up to ten  Gigabits per second. For the years ended December 31,  2007,
2008 and 2009, our on-net customers  generated  79.0%, 81.7% and  79.9%, respectively, of our total
service revenue.

In addition to providing our on-net services,  we also provide Internet  connectivity to customers

that are not located in buildings directly connected to our  network. We  serve these off-net customers
using other carriers’ facilities to provide the ‘‘last  mile’’  portion of  the  link  from our  customers’
premises to our network. For the years ended December 31, 2007, 2008  and 2009,  our off-net
customers generated 17.3%, 16.1%, and 18.4%, respectively, of our total service revenue.

Non-core services are those services we acquired and  continue to support  but do not actively  sell.
For the years ended December 31, 2007,  2008 and 2009, non-core services  generated 3.7%, 2.2%  and
1.7%, respectively, of our total service  revenue.

We  also operate 39 data centers comprising  over 352,000 square feet throughout North America

and Europe that allow customers to co-locate their equipment  and  access our network.

Competitive Advantages

We  believe we address many of the IP data communications needs  of small and medium-sized
businesses, communications service providers and other bandwidth-intensive organizations  by  offering
them high-quality Internet service at  attractive prices.

Low  Cost of Operation. We offer a streamlined set of products on an integrated network that
operates on a single protocol. Our network design allows  us  to  avoid many of  the costs associated with
circuit-switched networks related to provisioning, monitoring and maintaining multiple transport
protocols. We believe that our low cost of  operation gives us greater  pricing flexibility  and an  advantage
in a competitive environment characterized by falling Internet access  prices.

Independent Network. Our on-net service does not rely on infrastructure controlled by  local
incumbent telephone companies. We  provide the  entire network,  including the last mile and the
in-building wiring to the customer’s suite. This  gives  us more control over our  service,  quality and
pricing and allows us to provision services  more quickly and  efficiently. We are  typically able  to  activate
customer services in one of our on-net  buildings in  fewer than ten days.

High Quality, Reliable Service. We are able to offer high-quality Internet service due to our
network, which was designed solely to transmit  IP data, and dedicated intra-city bandwidth for  each

3

customer. This design increases the speed  and  throughput  of  our network and reduces  the number  of
data packets dropped during transmission.

Low  Capital Cost to Grow Our Business. We have incurred  relatively minimal indebtedness  in
growing our business because of our  network design of using  Internet routers without additional legacy
equipment and our strategy of acquiring optical fiber from the excess capacity in  existing networks.

Experienced Management Team. Our senior management team is composed of seasoned executives

with extensive expertise in the telecommunications industry as well as knowledge of the markets in
which  we operate.  The members of our senior management team  have an average  of over 20 years of
experience in the telecommunications  industry.  Our senior management team has designed and built
our  network and led the integration  of  our network assets, customers and service offerings we acquired
through 13 significant acquisitions.

Convergence. There is  a clear industry and market trend for  legacy products (e.g., TDM voice,
Private Line, Frame Relay, and Asynchronous  Transfer Mode)  to  be  replaced  with IP based services.
Many of our competitors will have to  migrate their existing customers  and products to IP. This
migration can be costly, lengthy, and risky. We do not face  this challenge because  our network and
products are IP.

Our Strategy

We  intend to become the leading provider  of high-quality Internet  access and IP communications

services and to continue to improve our profitability and cash flow. The principal  elements of our
strategy include:

Focus on Providing Low-Cost, High-Speed Internet Access and IP  Connectivity. We intend to further

load  our high-capacity network to respond to the growing demand for  high-speed  Internet service
generated by  bandwidth-intensive applications such  as streaming media, online gaming, video, voice
over IP (VOIP), remote data storage,  distributed  computing  and  virtual private  networks. We intend to
do so by continuing to offer our high-speed and high-capacity services  at competitive  prices.

Pursuing  On-Net Customer Growth. We intend to increase usage of our network  and operational
infrastructure by adding customers in our  existing on-net buildings, as  well as adding buildings to our
network.

Selectively Pursuing Acquisition Opportunities.

In addition to adding customers through our sales

and marketing efforts, we will continue to seek out  acquisition  opportunities that increase  our customer
base, allowing us to take advantage of the  unused  capacity of our network  and add  revenues with
minimal incremental costs. We may also make additional acquisitions to add network assets at attractive
prices.

Our Network

Our network is comprised of in-building  riser facilities, metropolitan optical networks,  metropolitan

traffic aggregation points and inter-city  transport facilities. We believe that  we deliver a high level of
technical performance because our network is  optimized for IP  traffic.  We believe that our  network is
more reliable and delivers IP traffic at  lower cost  than networks built as overlays to traditional  circuit-
switched telephone networks.

Our network serves over 140 metropolitan markets in  North  America and Europe  and

encompasses:

(cid:127) over 1,035 multi-tenant office buildings strategically located in commercial  business  districts;

4

(cid:127) over 410 carrier-neutral Internet aggregation  facilities,  data centers  and  single-tenant buildings;

(cid:127) over 330 intra-city networks consisting of over 13,300 fiber miles;

(cid:127) an inter-city network of more than 46,100 fiber route miles; and

(cid:127) multiple high-capacity transatlantic circuits connecting the  North  American and  European

portions of our network.

We  have created our network by acquiring optical  fiber from carriers  with large amounts  of  unused

fiber and  directly connecting Internet routers to our existing optical fiber national backbone. We have
expanded our network through key acquisitions  of  financially distressed  companies or their assets at a
significant discount to their original cost.  Due to our network design and acquisition strategy, we
believe we are positioned to grow our  revenue and increase profitability  with limited incremental
capital expenditures.

Inter-city Networks

Our inter-city network consists of optical  fiber connecting major  cities  in North  America and
Europe. The North American and European  portions of our network  are connected  by  transatlantic
circuits. Our network was built by acquiring from various owners of fiber optic networks the right to
use typically two strands of optical fiber  out of the multiple fibers owned by  the carrier. We have
installed the optical and electronic equipment necessary to amplify, regenerate, and route the optical
signals along these networks. We have  the right to use the fiber  under long  term agreements. We  pay
these providers fees for the maintenance of  the optical fiber  and provide our  own equipment
maintenance.

Intra-city Networks

In each metropolitan area in which we provide high-speed  on-net Internet access service, our
backbone network is connected to one or more routers  connected to one or more  of our  metropolitan
optical networks. We create our intra-city networks by obtaining the  right to use optical fiber  from
carriers with optical fiber networks in  those cities. These  metropolitan networks  consist of optical fiber
that runs from the central router in a market into routers located in  our on-net buildings. In most cases
the metropolitan fiber runs in a ring architecture, which  provides redundancy so  that  if  the fiber is cut,
data can still be transmitted to the central router  by  directing traffic in  the opposite  direction  around
the ring. The router in the building provides a  connection to each on-net  customer.

Within the cities where we offer off-net Internet  access service, we lease circuits from

telecommunications carriers, primarily local telephone companies, to provide the last mile connection
to the customer’s premises. Typically, these  circuits are aggregated  at  various locations  in those  cities
onto higher-capacity leased circuits that  ultimately  connect the local aggregation  route to our network.

In-Building Networks

In office buildings where we provide  service  to  multiple tenants we connect  our  routers to a cable
containing 12 to 288 optical fiber strands  that  typically run  from  our equipment in  the basement of the
building through the building riser to  the customer  location. Service  for customers is  initiated  by
connecting a fiber optic cable from a customer’s local  area network to the infrastructure  in the building
riser. The customer then has dedicated and  secure access  to  our network using an  Ethernet connection.
We  believe that Ethernet is the lowest cost  network  connection technology  and is used almost
universally for the local area networks that  businesses operate.

5

Internetworking

The Internet is an aggregation of interconnected networks. We have  settlement free
interconnections between our network  and  most major Internet Service Providers,  or ISPs, at
approximately 50 locations. We interconnect  our  network through  public and private peering
arrangements. Public peering is the means  by  which ISPs have traditionally connected to each other  at
central,  public facilities. Larger ISPs  also  exchange  traffic and interconnect their networks  by  means of
direct private connections referred to as  private peering.

Peering agreements between ISPs are necessary in order  for them  to  exchange traffic. Without
peering agreements, each ISP would  have to buy Internet access from every other  ISP  in order for  its
customer’s traffic, such as email, to reach  and be received from customers of other ISPs. We are
considered a Tier 1 ISP and, as a result, we  have settlement-free peering arrangements with  other
providers. This allows us to exchange  traffic with those  ISPs without payment  by  either party. In such
arrangements, each party exchanging traffic  bears its own  cost of delivering traffic to the point  at which
it is handed off to the other party. We also engage in public peering arrangements in which each party
also pays a fee to the owner of routing  equipment that  operates as the central exchange for all the
participants. We do not treat our settlement-free  peering arrangements as generating revenue or
expense related to the traffic exchanged.  However, we charge customers  representing  approximately
2,800 networks for transit services across our network and we  sell this service at  approximately  450
locations.

Network Management and Control

Our primary network operations centers are located  in Washington, D.C.  and Madrid, Spain. These

facilities provide continuous operational support in both North America and  Europe. Our network
operations centers are designed to immediately  respond  to any problems in our network. To ensure  the
quick replacement of faulty equipment  in  the intra-city and  long-haul networks, we have deployed  field
engineers across North America and  Europe. In addition, we have maintenance contracts with  third
party vendors that specialize in optical  and  routed  networks.

Our Services

We  offer high-speed Internet access and IP  connectivity primarily to small  and medium-sized

businesses, communications providers  and  other  bandwidth-intensive organizations  located  in North
America and Europe.

We  offer on-net services in over 140  metropolitan markets. We  serve over 1,450 buildings of  which

more than 1,230 are located in North America with the remainder  located in Europe. Our  most
popular on-net service in North America is  our  Fast  Ethernet  service, which provides  Internet access at
100 megabits per second. We typically  offer  our Fast Ethernet (Internet access) service to our  small and
medium-sized  business  customers  at  $1,000  a  month  for  month-to-month  service.  We  also  offer  Internet
access services at higher speeds of up to ten Gigabits per second. These  services are generally used  by
customers that have businesses, such as web hosting, that are  Internet based and  are generally delivered
at data centers and carrier hotels. We  believe that, on a per-Megabit  basis,  this service offering is  one
of the lowest priced in the marketplace. We also offer colocation services in 39 locations in  North
America and Europe. This service offers  Internet access combined with  rack  space and power in a
Cogent facility, allowing the customer to locate a server or other equipment  at that location  and
connect to our Internet service. Our  final on-net service offering is our  ‘‘Point-to-Point’’  or ‘‘Layer 2’’
service. These point-to-point connections span  North  America and Europe  and allow customers to
connect  geographically  dispersed  local  area  networks  in  a  seamless  manner.  We  offer  lower  prices  for
longer term and volume commitments. We emphasize the sale of on-net services  because we  believe
that we have a competitive advantage  in  providing these services and our sales of these services
generate higher gross profit margins.

We  offer off-net services to customers not located in our  on-net buildings.  These services  are
primarily provided in the metropolitan markets  in North America and Europe in which we offer on-net
services. These services are generally  provided to small  and medium-sized businesses in approximately
3,000 off-net buildings.

We  support certain non-core services assumed with certain of  our acquisitions. These services
primarily include dial-up Internet access  services and voice services (only  provided  in Toronto, Canada).
We  expect the revenue from these non-core services to decline. We  do not actively sell these services
and expect the growth of our on-net  Internet  services to compensate for this loss.

Sales and Marketing

Sales. We employ a direct sales and marketing approach  including telesales.  As of February  1,
2010, our sales force included 320 full-time employees. Approximately one-third  of these  employees are
located in our call centers with the remaining two-thirds located in our  sales  offices. Our outside  direct
sales personnel work through direct face-to-face contact  with potential customers in, or  intending to
locate in, on-net buildings. Through agreements with building owners, we  are able to initiate and
maintain personal contact with our customers by staging various promotional and social events in  our
on-net buildings. Direct sales personnel are compensated with a base salary plus  quota-based
commissions and incentives. We use  a  customer  relationship management system to efficiently track
activity levels and sales productivity.

Marketing. Because of our focus on a direct sales force,  we have  not  spent funds  on television,

radio or print advertising. Our marketing  efforts  are designed  to  drive awareness of our products  and
services, identify qualified leads through various direct  marketing  campaigns and provide our sales force
with product brochures, collateral materials, in building  marketing  events and relevant sales tools  to
improve the overall effectiveness of our sales organization.  In  addition, we conduct public relations
efforts focused on cultivating industry analyst  and media relationships  with the goal of securing  media
coverage and public recognition of our Internet communications  services.  Our marketing organization is
responsible for our product strategy and direction based upon  primary  and secondary  market research
and the advancement of new technologies.

Competition

We  face competition from incumbent  carriers, Internet service providers and facilities-based

network operators, many of whom are  much  larger than us, have significantly greater financial
resources, better-established brand names and large, existing  installed customer bases in the  markets in
which  we compete. We also face competition from other new  entrants to the communications  services
market. Many of these companies offer products  and services  that are similar to our products and
services. Unlike some of our competitors,  we do not have title to most of the  dark  fiber that makes up
our  network. Our interests in that dark  fiber are in  the form of long-term  leases or IRUs. We rely on
the maintenance of such dark fiber to  provide  our  on-net services to customers. We are also dependent
on third-party providers, for local loop  facilities for  the provision of connections to our off-net
customers.

We  believe that competition is based on  many  factors, including price,  transmission speed,  ease of

access and use, breadth of service availability, reliability of service, customer support and brand
recognition. Because our fiber optic  networks  have been recently installed compared  to  those of the
incumbent carriers, our state-of-the-art  technology may provide us with  cost, capacity, and service
quality advantages over some existing incumbent carrier networks; however, our network may  not
support some of the services supported  by  these legacy networks,  such as  circuit-switched  voice,  ATM
and frame relay. While the Internet access speeds offered by traditional  ISPs serving multi-tenant office
buildings typically do not match our on-net offerings, these slower  services are usually priced lower
than our offerings and thus provide competitive pressure on  pricing,  particularly for more price-
sensitive customers. These and other  downward  pricing pressures in carrier neutral data centers have
diminished, and may further diminish, the  competitive  advantages that we  have enjoyed as the result of
our  service pricing.

Regulation

In the United States, the Federal Communications Commission (FCC) regulates common carriers’

interstate services and state public utilities commissions  exercise  jurisdiction over intrastate basic
telecommunications services. Our Internet  service  offerings are not currently regulated  by  the FCC or
any state public utility commission. However, we may become subject to regulation  in the U.S. at  the
federal and state levels and in other  countries. These regulations change from time to time in ways that
are difficult for us to predict.

In the United States, we are subject to the obligations set forth in  the Communications  Assistance

for Law Enforcement Act, which is administered by  the FCC. That law requires  that  we be able to
intercept communications when required to do so by law enforcement  agencies. We are required  to
comply  or we may face significant fines and penalties. We are subject to similar requirements  in other
countries.

There is  no current legal requirement that owners  or managers  of commercial office  buildings give
access to competitive providers of telecommunications  services,  although the  FCC does prohibit carriers
from entering contracts that restrict the  right  of  commercial multiunit  property owners  to  permit any
other common carrier to access and serve  the property’s commercial tenants.

Our subsidiary, Cogent Canada, offers voice and Internet services  in Canada. Generally, the
regulation of Internet access services and competitive  voice services has been  similar in Canada to that
in the U.S. in that providers of such services  face fewer  regulatory requirements than the incumbent
local telephone company. This may change. Also,  the Canadian government  has requirements limiting
foreign ownership of certain telecommunications  facilities  in Canada. We are not subject to these
restrictions today. We will have to comply with these regulations to the extent they change and to the
extent we begin using facilities in a manner  that subjects us to these restrictions.

8

Our European and Mexican subsidiaries operate in  a more highly regulated environment for the

types of services they provide. In many  such countries, a  national  license  or a  notice filed with  a
regulatory authority is required for the provision  of  data and Internet services. In addition, our
subsidiaries operating in member countries of the European Union are subject  to  the directives  and
jurisdiction of the European Union. We  believe  that  each of our subsidiaries has the  necessary  licenses
to provide its services in the markets  where it operates  today. To  the  extent we  expand our operations
or service offerings into other new markets, we may face  new regulatory requirements particularly  in
non EU member countries.

The laws related to Internet telecommunications are unsettled and there  may be new legislation

and court decisions that may affect our  services and expose  us to liability.

Employees

As of February 1, 2010, we had 577 employees. A union  represents  twenty-two of our employees  in

France. We believe that we have a satisfactory relationship with our employees.

ITEM 1A. RISK FACTORS

If our operations do not consistently produce positive cash flow  to  pay for our growth or  meet our operating
and financing obligations, and we are unable to  otherwise raise  additional  capital to meet these  needs,  our
ability to implement our business plan will be  materially and adversely affected.

We  currently generate positive cash flow from our operations. We  are  not cash  flow positive

overall and we have limited funds available to us.  If we do  not become cash flow positive  or if we
acquire or invest in additional businesses,  assets, services or technologies  we  may need to raise
additional capital beyond that available  from our operating  cash flow. We may also face unforeseen
capital requirements for new technology required to remain competitive or to comply with  new
regulatory requirements, for unforeseen  maintenance  of  our  network  and facilities, and for  other
unanticipated expenses associated with  running our business. In addition, if  we do not retain existing
customers or add new customers, our cash flow may be impaired and  we  may be required  to  raise
additional funds through the issuance  of  debt or equity. We cannot  assure you  that  we will have access
to necessary capital, nor can we assure you  that any such financing will be available on  terms that are
acceptable to our stockholders or us.  If  issuing equity  securities raises additional funds, substantial
dilution to existing stockholders may result.

We need to retain existing customers and continue to  add  new  customers  in  order to become profitable and
cash flow positive.

In order to become profitable and consistently cash flow positive,  we  need to both  retain existing

customers and continue to add a large number of new customers. The precise number of additional
customers required to become profitable and  remain  consistently  cash flow positive  is dependent on  a
number of factors, including the turnover of  existing customers,  the pricing of our product offerings
and the revenue mix among our customers. We may not succeed  in adding customers if our sales and
marketing plan is unsuccessful. In addition,  many of our target customers are existing businesses  that

9

are already purchasing Internet access  services from one or more  providers, often under a  contractual
commitment. It has been our experience that  such target customers are often reluctant to switch
providers due to costs associated with  switching providers. Further, as  some of our customers grow
larger they may decide to build their own  Internet networks. While no single  customer accounted  for
more than 4.6% of our 2009 revenues, a migration  of a few very large  Internet  users to their own
networks or the loss or reduced purchases from several significant  customers could impair our growth.

Our growth and financial health are subject to a number of economic  risks.

Negative developments in the credit  and  financial markets  in the United States and worldwide
have resulted in extreme disruption in  recent months,  including, among other things, extreme volatility
in security prices, including our own, severely diminished liquidity and  credit  availability, rating
downgrades of certain investments and  declining valuations  of  others. If the  capital and  credit markets
continue to experience volatility and  the availability  of funds remains limited, it is possible that our
ability to access the capital and credit  markets  for significant purchases or  operations may  be  limited by
these conditions or other factors at a  time  when we would like, or need, to do so. This could have an
impact on our ability to react to changing economic and business conditions.

The economic downturn has significantly affected the  financial services  industry, which  includes
many  of our customers. In addition, the current  tightening of  credit in  financial  markets  potentially
adversely affects the ability of certain  of  our  customers to obtain  financing for  operations,  and could
result in a decrease in sales to new customers or existing  customers canceling services as well as impact
the ability of our customers to make  payments, which would  negatively impact our cash  flow. We are
unable to predict the likely duration  and  severity of the  current disruption  in financial markets and
adverse economic conditions in the U.S.  and  other countries.

We are experiencing rapid growth of our  business and operations and we may not  be  able to  efficiently
manage our growth.

We  have rapidly grown our company through network expansion and the acquisition of new
customers through our sales efforts. Our  expansion  places significant strains on our management,
operational and financial infrastructure. Our ability  to  manage our growth will be particularly
dependent upon our ability to:

(cid:127) expand, develop and retain an effective sales force and qualified personnel;

(cid:127) maintain the quality of our operations and our service offerings;

(cid:127) maintain and enhance our system of  internal controls to ensure  timely  and accurate compliance

with our regulatory reporting requirements; and

(cid:127) expand our accounting and operational information systems  in order to support our growth.

If we  fail to implement these measures  successfully, our ability to manage  our growth will  be  impaired.

We may  experience difficulties in implementing our expansion in Eastern  Europe and Mexico and may incur
related unexpected costs and regulatory  issues.

We  began to expand our network into  Eastern  Europe  in 2007 and into Mexico in 2009.  We have
experienced difficulty in acquiring dark  fiber and other  difficulties in  making our network operational
in these markets. The expansion may cost  more that we  have planned. We also may  experience
regulatory issues. Finally, we may be unsuccessful  in selling our services  in these markets. If  we are  not
successful in developing our market presence in Eastern Europe and Mexico  our  operating results
could be adversely impacted.

10

We may  experience delays and additional costs in expanding our on-net buildings.

Currently, we plan to increase our carrier-neutral facilities and other on-net buildings by
approximately 120 buildings in 2010 from 1,451 buildings at December  31, 2009.  We  may be
unsuccessful at identifying appropriate  buildings  or negotiating favorable terms for acquiring access  to
such buildings, and consequently, may  experience difficulty  in adding customers to our network  and
fully using the network’s capacity.

Our connections to the Internet require  us to establish and maintain relationships  with other providers, which
we may not be able to maintain.

The Internet is composed of various public and private network  providers who operate their own
networks and interconnect them at public and private interconnection points. Our network is one  such
network. In order to obtain Internet  connectivity for our network, we must establish  and maintain
relationships with other providers and incur the necessary capital  costs to locate  our  equipment and
connect our network at these various interconnection points.

By  entering into what are known as settlement-free peering arrangements, providers agree to
exchange traffic between their respective networks  without charging each other. Our ability to avoid the
higher  costs of acquiring paid dedicated  network capacity  and to maintain high network performance is
dependent upon our ability to establish and maintain peering relationships.  The terms and conditions
of our peering relationships may also be subject to adverse changes,  which we  may not be able  to
control. For example, several network operators with large numbers of individual users are arguing that
they should be able to charge or charge more to network operators and businesses that exchange  traffic
to those users. If we are not able to maintain or increase our peering  relationships in  all  of our  markets
on favorable terms, we may not be able  to provide  our customers with high performance or affordable
or reliable services, which could cause  us to lose existing and potential customers,  damage our
reputation and have a material adverse  effect on  our  business. We have in the past had disputes with
other network providers that resulted  in a  temporary disruption of  the  exchange of  traffic between our
network and the network of the other carrier. We have resolved the  majority of such  disputes through
negotiations. We continue to experience  resistance from  certain incumbent telephone companies,
especially in Europe, to the upgrade  of  settlement-free peering  connections necessary to accommodate
the growth of traffic we exchange with  such carriers. We  cannot assure you that we will be able to
continue to establish and maintain relationships with  providers  or favorably resolve  disputes  with
providers.

We may  be required to censor content on the  Internet, which we may  find difficult to  do and which may
impact our ability to provide service in  some  countries as well as impact the growth of Internet  usage,  upon
which we depend.

Some governments attempt to limit access to certain content  on the  Internet. It is  impossible for

us (and other providers as far as we know) to filter  all  content that flows across the Internet
connections we provide. For example, some content  is encrypted when a secure  web site  is accessed. It
is difficult to limit access to web sites that  engage in practices that make it difficult to block them  by
blocking a fixed set of Internet addresses.  Should  a government  require  us to perform these  types of
blocking procedures we could experience problems  ranging  from  additional expenses to a need to cease
providing service in that country. We  could also  be  subject to  penalties if  we fail to implement the
censorship.

We may  not successfully make or integrate acquisitions or enter into  strategic alliances.

As part of our growth strategy, we intend  to  pursue selected acquisitions  and strategic alliances. To

date,  we have completed 13 significant acquisitions. We compete  with other companies  for acquisition

11

opportunities and we cannot assure you that we  will be able to effect  future acquisitions or  strategic
alliances on commercially reasonable terms or  at all. Even if we enter  into these transactions, we may
experience:

(cid:127) delays in realizing or a failure to realize the  benefits we  anticipate;

(cid:127) difficulties or higher-than-anticipated costs associated with integrating any acquired  companies,

products or services into our existing business;

(cid:127) attrition of key personnel from acquired businesses;

(cid:127) unexpected costs or charges; or

(cid:127) unforeseen operating difficulties that require significant financial  and managerial  resources  that

would otherwise be available for the  ongoing  development or expansion of our existing
operations.

In the past, our acquisitions have often  included assets,  service offerings and financial obligations
that are not compatible with our core business strategy. We  have expended  management attention and
other resources to the divestiture of assets,  modification  of products  and  systems  as well as
restructuring financial obligations of  acquired operations. In most  acquisitions, we have  been successful
in renegotiating long-term agreements  that  we have acquired  relating to long distance and local
transport of data and IP traffic. If we are unable to satisfactorily  renegotiate such  agreements in the
future or with respect to future acquisitions, we may be exposed to large claims for payment for
services and facilities we do not need.

Consummating these transactions could also  result in the  incurrence of additional  debt  and related
interest expense, as well as unforeseen contingent  liabilities,  all of which  could  have a material adverse
effect on our business, financial condition  and  results of operations. Because we have purchased
financially distressed companies or their assets,  and  may  continue to do so in the  future, we have not
had, and may not have, the opportunity to perform extensive due diligence or  obtain  contractual
protections and indemnifications that  are  customarily  provided  in corporate  acquisitions. As a  result, we
may face unexpected contingent liabilities  arising from these acquisitions.  We may also issue  additional
equity in connection with these transactions, which would dilute our existing shareholders.

Revenues generated by the customer  contracts that  we have acquired  have accounted for a

substantial portion of our historical non-core and off-net service revenues. However, following an
acquisition, we have experienced a decline in revenue  attributable  to  acquired  customers  as these
customers’ contracts have expired and  they have  entered into standard Cogent customer contracts at
generally lower rates or have chosen  not  to  renew  service  with us. We anticipate that we will experience
similar declines with respect to customers we may acquire in  the future.

We depend upon our key employees and may  be unable to attract or retain sufficient  qualified personnel.

Our future performance depends upon the  continued  contribution of our executive management

team and other key employees, in particular,  our Chairman and Chief Executive  Officer, Dave
Schaeffer. As founder of our company,  Mr. Schaeffer’s knowledge  of our  business  and our industry
combined with his deep involvement in every  aspect  of  our  operations and planning make him
particularly well-suited to lead our company and difficult  to  replace.

12

Our business could suffer because telephone  companies and  cable  companies may provide better delivery  of
Internet content originating on their own  networks.

Broadband connections provided by cable TV and telephone companies have  become the
predominant means by which consumers  connect to the Internet. The  providers  of  these  broadband
connections may treat Internet content delivered from different  sources differently. The possibility of
this  has been characterized as an issue  of  ‘‘net neutrality.’’ As many of our customers operate websites
and services that deliver content to consumers our ability  to sell our services would  be  negatively
impacted if Internet content delivered  by us was less easily received by consumers  than Internet  content
delivered by others.

We have  substantial debt which we may  not  be  able to repay when due.

Our total indebtedness, net of discount, at  December  31, 2009 was $175.9 million.  As of

December 31, 2009, we have $92.0 million of face value of senior  convertible notes  outstanding. The
holders  of the notes have the right to  compel us  to  repurchase  for  cash on June 15, 2014,  June 15,
2017 and June 15, 2022, all or some of their notes. They also  have the right to be paid  the principal
upon default and upon certain designated events, such as  certain changes of control.  We may not have
sufficient funds to pay the principal at  the time  we are  obligated  to  do so, which could result in
bankruptcy, or we may only be able to raise the necessary  funds on unfavorable terms.

Our total indebtedness at December 31,  2009 includes $109.7 million  of  capital lease obligations
for dark fiber primarily under 15 - 25  year IRUs, of which approximately  $5.6 million is considered a
current liability. The amount of our IRU  capital lease obligations  may  be  impacted  due  to  our
expansion activities and fluctuations in  foreign currency rates.

Our operations outside of the United States  expose us  to economic,  regulatory and  other  risks.

The nature of our European, Canadian, and Mexican  businesses involve a number of risks,

including:

(cid:127) fluctuations in currency exchange rates;

(cid:127) exposure to additional regulatory and legal requirements, including import restrictions  and

controls, exchange controls, tariffs and other  trade barriers;

(cid:127) difficulties in staffing and managing our foreign  operations;

(cid:127) changes in political and economic  conditions; and

(cid:127) exposure to additional and potentially adverse tax regimes.

As we continue to expand into other  countries, our  success will depend,  in part, on  our  ability  to
anticipate and effectively manage these  and other risks. Our  failure to manage  these risks and grow our
operations outside the U.S. may have a material adverse effect  on our business and results of
operations.

Fluctuations in foreign exchange rates may adversely affect our  financial position  and results  of operations.

Our operations outside the U.S. expose us to currency fluctuations  and exchange rate risk. For
example, while we record revenues and financial results  from  our European  operations in Euros, these
results are reflected in our consolidated  financial statements in  U.S.  dollars. Therefore, our reported
results are exposed to fluctuations in the  exchange rates between  the U.S.  dollar and  the Euro. We
fund certain of our cash flow requirements of  our  European, Canadian  and  Mexican operations  in U.S.
dollars. Accordingly, in the event that  their  currencies  strengthen  versus  the dollar to a greater extent
than we anticipate, the cash flow requirements associated with these operations  may be significantly
greater in U.S.-dollar terms than planned.

13

Our business could suffer delays and problems due  to the actions of network providers on whom we are
partially dependent.

Our off-net customers are connected  to our network by means of communications lines  that  are
provided as services by local telephone companies  and  others. We  may experience problems  with the
installation, maintenance and pricing of  these lines  and  other communications links, which could
adversely affect our results of operations  and our plans to add additional customers to our network
using such services. We have historically  experienced  installation and maintenance delays when  the
network provider is devoting resources  to  other  services, such as  traditional telephony. We have also
experienced pricing problems when a  lack  of alternatives allows  a  provider  to  charge high prices for
services in an area. We attempt to reduce this  problem by  using many different providers so that we
have alternatives for linking a customer  to our network. Competition among the providers tends to
improve installation, maintenance and  pricing.

Our network could suffer serious disruption if certain locations experience  serious damage.

There are certain locations through which a  large amount of our Internet traffic passes.  Examples

are facilities in which we exchange traffic  with other carriers,  the facilities through which our
transatlantic traffic passes, and certain of  our network hub sites.  If any  of these facilities were
destroyed or seriously damaged a significant amount of our network  traffic  could  be  disrupted. Because
of the large volume of traffic passing  through these facilities our ability  (and the ability of carriers with
whom we exchange traffic) to quickly restore service would be challenged. There could be parts of our
network or the networks of other carriers  that could  not  be  quickly  restored or that would experience
substantially reduced service for a significant  time. If  such a disruption occurs,  our reputation could be
negatively impacted which may cause  us to lose customers and  adversely affect our ability to attract
new  customers,  resulting  in  an  adverse  effect  on  our  business  and  operating  results.

If the information systems that we depend on to support  our customers, network operations, sales, billing and
financial reporting do not perform as expected, our operations and our financial  results may be adversely
affected.

We  rely  on complex information systems to operate our network and support our other business

functions. Our ability to track sales leads,  close sales opportunities, provision services, bill our
customers for those services and prepare our financial  statements depends upon the effective
integration of our various information systems. If  our  systems, individually or  collectively, fail  or do not
perform as expected, our ability to process and provision orders, to make timely payments  to  vendors,
to ensure that we collect amounts owed  to  us  and  prepare our financial statements would  be  adversely
affected. Such failures or delays could result in increased capital expenditures, customer and  vendor
dissatisfaction, loss of business or the  inability to add new customers  or additional services, and  prepare
accurate and timely financial statements all  of which would adversely affect our  business  and results of
operations.

We have  historically incurred operating  losses and these losses  may  continue  for the foreseeable future.

Since we initiated operations in 2000, we  have generated operating losses and these  losses may
continue for the foreseeable future. In 2007 we had  an operating  loss of $29.9 million,  in 2008 we had
an operating loss of $22.2 million and in 2009 we had  an operating  loss of $3.8 million.  As of
December 31, 2009, we had an accumulated  deficit of  $332.7  million.  Continued losses may prevent us
from pursuing our strategies for growth  or may  require us to seek unplanned additional capital and
could cause us to be unable to meet  our debt service obligations, capital  expenditure requirements or
working capital needs.

14

We may  have difficulty intercepting communications as  required by the U.S. Communications Assistance  for
Law Enforcement Act and similar laws of  other countries.

The U.S. Communications Assistance for Law Enforcement  Act  and the laws of  other  countries

require that we be able to intercept communications when required to do so by law enforcement
agencies. We may experience difficulties and incur  significant costs in complying  with these laws. If we
are unable to comply with the laws we could be subject to fines in  the United States  of  up to
$1.0 million per event and equal or greater  fines in other countries.

Our business could suffer from an interruption of service from our fiber providers.

The carriers from whom we have obtained our inter-city and intra-city  dark fiber maintain that
fiber. If these carriers fail to maintain the  fiber or disrupt our fiber connections for  other reasons,  such
as business disputes with us and governmental takings, our ability to provide  service  in the affected
markets or parts of markets would be impaired. The companies  that maintain our inter-city dark fiber
and many of the companies that maintain our  intra-city dark fiber are also  competitors of ours.
Consequently, they may have incentives  to act in  ways unfavorable to us. While we have  successfully
mitigated the effects of prior service interruptions and business disputes in  the past, we may incur
significant delays and costs in restoring service to our customers  in connection with future  service
interruptions, and we may lose customers if  delays are  substantial.

Our business depends on agreements with  carrier neutral data center operators, which we could  fail  to obtain
or maintain.

Our business depends upon access to  customers in  carrier neutral data  centers, which  are facilities

in which many large users of the Internet house the  computer servers that deliver content and
applications to users by means of the Internet and provide  access to multiple  Internet access  networks.
Most carrier neutral data centers allow  any carrier to operate within the facility (for a  standard fee).
We  expect to enter into additional agreements with carrier neutral data center operators as part of our
growth plan. Current government regulations do not require carrier neutral data center  operators to
allow all carriers access on terms that are reasonable  or nondiscriminatory. We have been  successful in
obtaining agreements with these operators in  the past and  have generally found  that  the operators want
to have us in their facilities because we  offer  low-cost, high capacity Internet  service  to  their  other
customers. Any deterioration in our  existing  relationships with these operators could harm  our sales
and marketing efforts and could substantially  reduce our potential customer base. The proposed  merger
of two large operators of such facilities, Switch  & Data Facilities Company, Inc.  and Equinix, Inc.,
could negatively impact us if the combined entity does  not continue to operate its facilities in  a carrier
neutral fashion.

Our ability to serve customers in multi-tenant office  buildings  depends on license  agreements with building
owners and managers, which we could fail  to obtain or  maintain.

Our on-net business depends upon our in-building networks. Our in-building networks  depend  on

access agreements with building owners or  managers  allowing us to install  our in-building  networks and
provide our services in these buildings.  These  agreements typically have terms of five to ten years, with
one or more renewal options. Any deterioration in  our existing relationships with building owners or
managers could harm our sales and marketing  efforts and  could  substantially reduce our potential
customer base. We expect to enter into  additional access  agreements as  part of our growth plan.
Current federal and state regulations do  not require  building owners  to  make  space available to us or
to do so on terms that are reasonable or  nondiscriminatory. While the FCC has adopted regulations
that prohibit Common Carriers under its  jurisdiction from entering into exclusive arrangements  with
owners of multi-tenant commercial office  buildings, these  regulations do not require  building owners to
offer us access to their buildings. Building owners or managers may decide not to permit us to install

15

our  networks in their buildings or may elect not to renew or amend  our access  agreements. The initial
term of most of our access agreements  will conclude in the  next several years. Most  of  these
agreements have one or more automatic renewal  periods and others may  be  renewed at the option of
the landlord. While we have historically been  successful in  renewing  these agreements  and no single
building access agreement is material to our  success, the failure  to  obtain or maintain a number of
these agreements would reduce our revenue, and we might not recover our costs  of procuring building
access and installing our in-building networks.

We may  not be able to obtain or construct additional building laterals to connect  new buildings to our
network.

In order to connect a new building to our network we  need to obtain  or construct a  lateral from
our  metropolitan network to the building.  We  may  not be able to obtain  fiber in an existing lateral at
an attractive price from a provider and may not be able to construct  our  own lateral due to the  cost of
construction or municipal regulatory restrictions. Failure to obtain fiber  in an existing  lateral or to
construct a new lateral could keep us from adding  new buildings  to  our network and from increasing
our  revenues.

Impairment of our intellectual property rights and our alleged infringement  on other companies’  intellectual
property rights could harm our business.

We  are aware of several other companies in our and other industries that  use the word ‘‘Cogent’’

in their corporate names. One company  has informed us that  it believes our  use of the  name ‘‘Cogent’’
infringes  on their intellectual property  rights  in that name.  If such a challenge is  successful, we could be
required to change our name and lose the goodwill associated with  the Cogent name in  our markets.

The sector in which we operate is highly competitive, and  we may not  be  able  to  compete effectively.

We  face significant competition from incumbent carriers,  Internet service providers and facilities-

based network operators. Relative to  us,  many  of these  providers have significantly greater financial
resources, more well-established brand  names, larger customer bases,  and  more diverse strategic  plans
and service offerings.

Intense competition from these traditional and  new  communications companies  has led to

declining prices and margins for many communications  services,  and we expect this trend to continue as
competition intensifies in the future. Decreasing prices for high-speed  Internet  services have somewhat
diminished the competitive advantage  that we have  enjoyed as a result of our service pricing.

Our competitors may also introduce new technology or services  that make  our services  less

attractive to potential customers.

We issue projected results and estimates for  future periods from time to time,  and  such  projections and
estimates are subject to inherent uncertainties and may prove to  be inaccurate.

Financial information, results of operations and other projections that we may issue from time to

time are based upon our assumptions  and  estimates. While we  believe these assumptions and estimates
to be reasonable when they are developed, they are inherently subject to  significant  business,  economic
and competitive uncertainties and contingencies, many of  which are  beyond our control. You should
understand that certain unpredictable  factors could cause our  actual  results to differ from our
expectations and those differences may be material. No independent expert  participates in  the
preparation of these estimates. These  estimates should not be regarded as a representation by us as to
our  results of operations during such periods  as there  can be no assurance that any of these estimates
will be realized. In light of the foregoing,  we  caution  you not to place undue  reliance  on these
estimates. These estimates constitute forward-looking  statements.

16

The utilization of our certain of net operating loss carryforwards are limited and depending upon the  amount
of our taxable income we may be subject  to  paying income taxes earlier than planned.

Due to the uncertainty surrounding the  realization of our net  deferred tax asset, we have recorded
a valuation allowance for the majority of  our net  deferred  tax asset. As of December 31, 2009,  we have
combined net operating loss carry-forwards of approximately $1.1 billion. This amount includes federal
and state net operating loss carry-forwards in  the United  States  of approximately  $400 million, net
operating loss carry-forwards related  to  our Canadian operations of approximately $4  million and net
operating loss carry-forwards related  to  our European operations  of approximately $680 million.
Section 382 of the Internal Revenue Code in the United States  limits the utilization of  net operating
losses when ownership changes, as defined by that section, occur.  We have performed an analysis of
our  Section 382 ownership changes and have determined that the utilization of certain  of  our  net
operating loss carryforwards in the United States may be limited. This restricted amount includes the
limitation on annual utilization related to the remaining $183 million of federal and state  net operating
loss carry-forwards of Allied Riser Communications Corporation that were acquired by us via a 2002
merger.

Network failure or delays and errors in  transmissions  expose us to potential liability.

Our network is part of the Internet which is a  network of networks. Our network uses a collection

of communications equipment, software, operating protocols  and proprietary applications  for the
high-speed transportation of large quantities of data  among  multiple locations.  Given the complexity  of
our  network, it is possible that data will  be lost or  distorted. Delays in data delivery may  cause
significant losses to one or more customers using our network. Our  network  may also contain
undetected design faults and software bugs that, despite  our testing, may  not be discovered  in time  to
prevent harm to our network or to the data transmitted over it. The failure of  any equipment  or facility
on the network could result in the interruption of customer  service until we  effect necessary repairs or
install replacement equipment. Network  failures,  delays and errors  could also result from  natural
disasters, power losses, security breaches,  computer  viruses, denial of service attacks and  other  natural
or man-made events. Our off-net services are dependent  on the network facilities of other providers or
on local  telephone companies. Network  failures, faults or  errors could cause delays  or service
interruptions, expose us to customer  liability or  require expensive modifications that could have a
material adverse effect on our business.

As  an Internet access provider, we may incur liability for  information disseminated  through our network.

The law relating to the liability of Internet access providers and on-line  services  companies for
information carried on or disseminated through their networks is  unsettled.  As the law in  this  area
develops and as we expand our international operations,  the potential imposition of liability upon us
for information carried on and disseminated through our network could require us to implement
measures to reduce our exposure to such liability, which may require  the expenditure of  substantial
resources or the discontinuation of certain products or service offerings. Any costs that are incurred as
a result of such measures or the imposition of liability could harm our  business.

The holders of our senior convertible notes have the right to convert  their notes  to common stock.

The holders of our senior convertible  notes are  under certain  circumstances able  to  convert  their

notes into common stock at a conversion price of  $49.18 per  share of common stock and  to  obtain
additional shares of common stock. If  our  share  price exceeds $49.18 and the conversion right  is
exercised by the holders of the notes the  number of our shares of common stock outstanding  will
increase which could reduce further appreciation in  our  stock price and impact  our  per  share earnings.
Rather than issue the stock we are permitted to pay the  cash equivalent in value to the stock  to  be

17

issued. We might not have sufficient funds  to  do this  or doing so might have other detrimental  impacts
on us.

Legislation and government regulation  could  adversely affect us.

As an Internet service provider, we are not subject to substantial regulation by the FCC  or the

state public utilities commissions in the  United States. Internet  service is also  subject to minimal
regulation in Western Europe and in  Canada.  In  Eastern  Europe and  Mexico the regulation is greater,
though not as extensive as the regulation  for providers of voice services. If  we decide to offer
traditional voice services or otherwise  expand our service offerings  to  include services that would  cause
us to be deemed a common carrier, we will become subject to additional  regulation. Additionally, if we
offer voice service using IP (voice over  IP) or offer certain  other types of data services using IP we  may
become  subject to additional regulation.  This regulation could impact our business because of the  costs
and time required to obtain necessary authorizations,  the additional taxes than  we may become subject
to or may have to collect from our customers,  and  the additional administrative costs  of providing  voice
services, and other costs. Even if we  do  not  decide to offer additional services, governmental authorities
may decide to impose additional regulation and  taxes upon providers of Internet service. All  of  these
could inhibit our ability to remain a low  cost  carrier and  could  have a  material adverse effect on our
business, financial condition or results  of  operations.

Much of the law related to the liability of  Internet service providers remains unsettled. For
example, many jurisdictions have adopted laws related to unsolicited commercial email or  ‘‘spam’’ in
the last several years. Some jurisdictions  have  laws,  regulations, or court decisions  that  impose upon
Internet access providers obligations to  restrict  access to certain content.  Other  legal issues, such as the
sharing of copyrighted information, transborder data flow, universal  service, and  liability  for software
viruses could become subjects of additional legislation  and legal development. We cannot  predict the
impact of these changes on us. Regulatory  changes could have a material  adverse  effect  on our
business, financial condition or results  of  operations.

Terrorist activity throughout the world,  military action to counter  terrorism  and natural disasters could
adversely impact our business.

The September 11, 2001 terrorist attacks in the  United States and the continued threat  of  terrorist

activity and other acts of war or hostility have had,  and may  continue to have, an  adverse  effect  on
business, financial and general economic  conditions internationally. Effects from these events and any
future terrorist activity, including cyber  terrorism, may, in  turn, increase our costs due to the need to
provide enhanced security, which would  adversely affect  our business and results of operations. These
circumstances may also damage or destroy  the Internet infrastructure and may adversely  affect our
ability to attract and retain customers, our  ability  to  raise capital  and  the  operation and maintenance  of
our  network access points. We are particularly vulnerable to acts  of terrorism because our largest
customer concentration is located in  New  York,  our  headquarters is in  Washington, D.C., and we have
significant operations in Paris, Madrid and London,  cities that  have historically been  targets for
terrorist attacks. We are also susceptible  to  other catastrophic events such as major natural disasters,
extreme weather, fire or similar events  that could  effect our headquarters, other offices,  our  network,
infrastructure or equipment, which could  adversely affect our  business.

ITEM 2. DESCRIPTION OF PROPERTIES

We  lease and own space for offices, data centers, colocation facilities, and points-of-presence.

Our headquarters facility consists of  approximately 15,370  square feet located in Washington, D.C.

The lease for our headquarters is with an entity controlled by  our Chief Executive  Officer.  The  lease
expires on August 31, 2012.

18

We  also lease a total of approximately 483,000 square  feet of space in 80  locations to house our

colocation facilities, corporate headquarters,  regional offices and  operations centers.  The remaining
term of these leases ranges from 3 months to 10 years with, in  many cases, options to renew.

We  believe that these facilities are generally in  good condition and  suitable  for our operations.

ITEM 3. LEGAL PROCEEDINGS

We  are involved in legal proceedings in the normal course  of our  business that we do  not  expect to

have a material adverse affect on our  business,  financial  condition or results of operations. For  a
discussion of the significant proceedings  in which we  are involved,  see Note 6 to our consolidated
financial statements.

ITEM 4. SUBMISSION OF MATTERS TO A VOTE OF SECURITY HOLDERS.

No matters were submitted to a vote  of our security holders during  the quarter ended

December 31, 2009.

ITEM 7. MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION  AND

RESULTS OF OPERATIONS

You should read the following discussion and analysis together with ‘‘Selected Consolidated  Financial

Data’’ and our consolidated financial statements  and  related  notes included  in this  report. The discussion in
this report contains forward-looking statements that involve risks and uncertainties, such  as statements of
our plans, objectives, expectations and  intentions. The  cautionary statements made in this report  should  be
read as applying to all related forward-looking statements wherever  they appear in this report.  Our actual
results could differ materially from those discussed here.  Factors that could cause or  contribute  to these
differences include those discussed in ‘‘Risk  Factors,’’ as well as  those discussed elsewhere. You should read
‘‘Risk Factors’’ and ‘‘Special Note Regarding Forward-Looking Statements.’’

General Overview

We are a leading facilities-based provider of low-cost, high-speed Internet access and

IP communications services. Our network is specifically designed and optimized to transmit  data  using
IP.  IP networks are significantly less expensive to operate and are able to achieve higher  performance
levels than the traditional circuit-switched  networks  used  by many of our  competitors when  providing
Internet access services, thus, we believe, giving us cost and performance  advantages.  We deliver our
services to small and medium-sized businesses,  communications  service providers and other bandwidth-
intensive organizations through approximately 21,300 customer  connections  in North  America and
Europe. Our primary on-net service is  Internet access at a speed of 100 Megabits per second  or greater
to customers in multi-tenant office buildings, much faster than  typical Internet access  currently offered
to businesses. We offer this on-net service exclusively  through our own  facilities,  which run all the way
to our customers’ premises.

We provide on-net Internet access to our net centric customers,  which include certain bandwidth-

intensive users such as universities, other Internet service providers,  telephone  companies, cable
television companies and commercial content providers at speeds up to 10 Gigabits  per  second. These
customers generally receive service in  colocation facilities  and in our  data centers. We also provide
Internet access services to our corporate  customers in multi-tenant  office buildings typically serving law
firms, financial services firms, advertising  and marketing firms and  other professional services
businesses.

Our network is comprised of in-building  riser facilities, metropolitan optical fiber networks,

metropolitan traffic aggregation points and inter-city transport facilities.  The  network is  physically
connected entirely through our facilities  to  over 1,450 buildings  in which we provide our on-net
services, including 1,035 multi-tenant office  buildings. We also provide on-net services in carrier-neutral
colocation facilities, Cogent controlled  data centers and single-tenant office buildings.  Because of our
integrated network architecture, we are not dependent  on  local  telephone companies  to  serve our
on-net customers. We emphasize the  sale of on-net services because we believe we have a  competitive
advantage in providing these services and our  sales of  these  services generate higher gross profit
margins than our off-net and non-core services.

We also provide Internet connectivity to customers that  are not located in buildings directly
connected to  our network. We serve these off-net customers using other  carriers’  facilities  to  provide
the last mile (local loop) portion of the link from our customers’  premises to our network. We also
provide certain non-core services which are legacy services which we acquired and continue  to  support
but do not actively sell.

We believe our key growth opportunity is  provided  by our high-capacity network,  which provides us

with the ability to add a significant number of customers to our  network with minimal incremental
costs. Our focus is to add customers to our network in a way  that maximizes its use and  at the same
time provides us with a profitable customer mix. We are responding to this opportunity  by  increasing

23

our  sales and marketing efforts including increasing our number of sales representatives.  In addition,
we may add customers to our network  through  strategic acquisitions.

We  are expanding our network to locations that  we believe  can  be  economically integrated and

represent significant concentrations of Internet traffic.  One  of  our keys  to developing a profitable
business will be to carefully match the expense of extending  our network to reach new  customers  with
the revenue expected to be generated  by  those customers.

We  believe two of the most important trends  in our industry are  the continued long-term growth in

Internet traffic and a decline in Internet  access prices within carrier  neutral data centers. As Internet
traffic continues to grow and prices per  unit of traffic continue  to  decline,  we believe  our  ability  to  load
our  network and gain market share from  less efficient network operators  will continue to expand.
However, continued erosion in Internet  access prices  will likely  have a negative impact on the rate at
which  we can increase our revenues and our  profitability. In June 2008, we introduced additional
volume and term based discounts to  certain of our customers  in an effort to continue to gain  market
share and grow our on-net revenues.

Our on-net service consists of high-speed Internet access and IP connectivity ranging from

0.5 Megabits per second to 10 Gigabits  per  second  of bandwidth.  We offer our on-net services to
customers located in buildings that are physically connected to our network.  Off-net  services are sold to
businesses that are connected to our network primarily  by means of ‘‘last  mile’’ access  service  lines
obtained from other carriers, primarily in the form of  point-to-point TDM, POS, SDH and/or Carrier
Ethernet circuits. Our non-core services,  which consist  primarily  of legacy services of  companies whose
assets or businesses we have acquired  primarily include dial-up Internet  access services  and voice
services (only provided in Toronto, Canada). We do  not  actively market these non-core services and
expect the service revenue associated  with them to continue  to  decline.

The growth in Internet traffic has a more significant  impact on our net-centric  customers who
represent the majority of the traffic on  our  network and who tend to consume the majority  of  their
allocated bandwidth on their connections. Net-centric customers tend  to  purchase their service on a
price per megabit basis. Our corporate customers tend to utilize a small portion of their allocated
bandwidth on their connections and  tend  to purchase their service on  a per connection basis.

Due to our strategic acquisitions of network assets  and equipment, we believe we are positioned to

grow our revenue base. We continue to purchase  and  deploy network equipment to parts  of our
network to maximize the utilization of our assets and to expand  our network. Our future  capital
expenditures will be based primarily on  our planned expansion of our  network, the addition of on-net
buildings and the concentration and growth of our customer  base.  We plan to continue to expand our
network and to increase our number of  on-net buildings by approximately 120  buildings by
December 31, 2010 from 1,451 buildings at December 31, 2009. We  expect our 2010 capital
expenditures to be approximately 20% lower than  our 2009 capital expenditures.

Historically, our operating expenses have exceeded  our  net service  revenue  resulting in  operating
losses of $29.9 million, $22.2 million  and $3.8  million  in 2007, 2008  and 2009, respectively.  In each  of
these periods, our operating expenses consisted primarily  of the following:

(cid:127) Network operations expenses, which  consist primarily of the cost  of leased circuits,  sites and
facilities, telecommunications license agreements, maintenance expenses, and  salaries of, and
expenses related to, employees who are directly involved with  maintenance and operation  of  our
network.

(cid:127) Selling, general and administrative expenses, which consist  primarily of  salaries, commissions  and

related benefits paid to our employees and other selling and  administrative  costs including
professional fees and bad debt expenses.

24

(cid:127) Depreciation and amortization expenses, which  result from the depreciation  of our  property and

equipment, including the assets associated  with our network.

(cid:127) Equity-based compensation expenses that result  from grants of stock  options and restricted

stock.

Results of Operations

Our management reviews and analyzes  several key performance indicators  in order to manage our
business and assess the quality of and  potential variability  of  our service  revenues  and cash flows. These
key performance indicators include:

(cid:127) Service revenues, which are an indicator  of our overall business  growth and the success of our

sales and marketing efforts;

(cid:127) growth  in  our  customer  base  and  revenues,  which  is  an  indicator  of  the  success  of  our  sales

efforts;

(cid:127) growth in our on-net buildings; and

(cid:127) cash flows.

(1) Excludes equity-based compensation  expense of $328 and $172 in the  years  ended

December 31, 2008 and 2009, respectively, which,  if  included would  have resulted in a
period-to-period change of 10.4%.

(2) Excludes equity-based compensation  expense of $17,548 and $8,435 in the  years  ended
December 31, 2008 and 2009, respectively, which,  if  included would  have resulted in a
period-to-period change of (4.4)%.

Service Revenue. Our service revenue increased 9.4% from $215.5 million for  the year  ended
December 31, 2008 to $235.8 million for the year  ended December 31, 2009. The impact of  exchange
rates negatively impacted the increase  in revenues by approximately $3.9 million. All foreign currency
comparisons herein reflect results for the  year ended December 31, 2009 translated at  the average

25

foreign currency exchange rates for the  year ended December 31, 2008.  For the  years  ended
December 31, 2008 and 2009, on-net,  off-net and  non-core revenues  represented 81.7%, 16.1% and
2.2% and 79.9%, 18.4% and 1.7% of  our net service revenues,  respectively.

Revenues from our corporate and net  centric customers represented 44.7%  and 55.3%  of our
service revenue, respectively, for the  year  ended December 31, 2008 and represented 47.3% and 52.7%
of our service revenue, respectively, for the year ended  December 31,  2009. Revenues from  corporate
customers increased 15.9% from $96.3 million for the year  ended  December 31, 2008 to $111.6  million
for the year ended December 31, 2009.  Revenues  from our net-centric customers increased 4.2% from
$119.2 million for the year ended December 31, 2008  to  $124.2 million for the year ended
December 31, 2009. The difference in  the increase percentages  in net centric revenues  as compared  to
the increase in corporate revenues is  primarily attributed  to  a decline in the  average revenue  per  net
centric customer connection from discounting  and from  the impact  of exchange rates  (almost  all  of our
European revenues are from net centric  customers).  In June 2008,  we  introduced  additional volume
and term based discounts to certain of our net  centric customers in  an effort to continue  to  gain
market share and to continue to grow  our  revenues.

Our on-net revenues increased 7.1% from $176.0 million for the year ended  December 31, 2008 to

$188.5 million for the year ended December 31, 2009.  Our on-net revenues  increased  as we  increased
the number of our on-net customer connections  by 21.5%  from approximately 14,100 at December  31,
2008 to approximately 17,200 at December  31, 2009. On-net  customer connections increased at a
greater rate than on-net revenues due  to  a  decline  in the average revenue  per  on-net customer
connection—primarily from our net centric customers. This decline  is partly attributed to a shift  in the
customer connection mix and due to  volume and term  based pricing discounts. Due to the increase in
the size of our sales force, we are now able  to  focus not only  on  customers who  purchase
high-bandwidth connections, as we have  done  historically, but also on  customers who purchase lower-
bandwidth connections. We expect to continue to focus our sales efforts on a broad mix of customers.
Additionally, on-net customers who cancel their service from our installed base of customers, in
general, have greater average revenue per connection than new  customers.  These trends and  the impact
of foreign exchange rates resulted in  a reduction to our  average revenue per on-net connection.

Our off-net revenues increased 25.3%  from $34.6 million for the year  ended December  31, 2008 to
$43.3 million for the year ended December 31, 2009.  Our  off-net customer  connections increased 6.4%
from approximately 3,000 at December  31, 2008 to approximately 3,200 at December 31, 2009.  Off-net
revenues increased at a greater rate than off-net customer connections due to an  increase in the
average revenue per off-net customer connection. Off-net  customers who cancel their service, in
general, have an average revenue per  connection and per connection bandwidth speed that is less than
the average revenue per connection for  new off-net  customers who generally purchase higher-
bandwidth connections.

Our non-core revenues decreased 17.6%  from $4.9 million for the year ended  December 31,  2008

to $4.0 million for the year ended December 31, 2009. The number  of  our  non-core customer
connections increased 51.1% from approximately  600 at December 31, 2008 to approximately 900  at
December 31, 2009 primarily due to the  May 2009 acquisition of approximately 700  non-core customer
connections. We do not actively market  these acquired  non-core services and expect  that  the net service
revenue associated with them will continue to decline.

Network Operations Expenses. Our network operations expenses, excluding equity-based

compensation expense, increased 10.7%  from $92.7 million for the year ended December 31,  2008 to
$102.6 million for the year ended December 31, 2009.  The impact  of exchange rates  resulted in  a
reduction of network operations expenses for  the year ended December 31, 2009  of approximately
$1.4 million. The increase in network  operations  expenses is primarily  attributable  to  an increase in
costs related to our network and facilities expansion activities and an increase in  our off-net  revenues.
When we provide off-net revenues we also assume the cost  of the associated  tail-circuits.

26

Selling, General, and Administrative Expenses  (‘‘SG&A’’). Our SG&A expenses, excluding equity-

based compensation expense, increased  8.8% from $62.9  million for the  year ended December  31, 2008
to $68.5 million for the year ended December 31, 2009. SG&A  expenses increased primarily from the
increase in salaries and related costs required  to  support our expanding  sales  and marketing efforts.
The impact of exchange rates resulted in  a reduction  of  approximately  $1.2 million in SG&A expenses.

Equity-based Compensation Expense. Equity-based compensation expense is related to restricted

stock and stock options. Our total equity-based  compensation  expense decreased 51.9% from
$17.9 million for the year ended December 31, 2008  to  $8.6 million for the year ending December 31,
2009. Equity-based compensation expense  decreased primarily due  to  the completion of the  service
period in April 2009 of certain restricted stock  grants made  in April  2007 and  $1.2 million of equity-
based compensation expense related to share grants made to our board of directors  in January 2008.
There were no such grants to our board  of directors in  2009.

Depreciation and Amortization Expenses. Our depreciation and amortization expense decreased
4.3% from $62.6 million for the year ended December  31, 2008 to $59.9  million  for the  year  ended
December 31, 2009. The decrease is primarily due to the decline in depreciation  expense from fully
depreciated fixed assets more than offsetting depreciation  expense associated  with the increase  in
deployed fixed assets. The impact of  exchange  rates  resulted in a reduction of approximately
$0.6 million in depreciation and amortization expenses.

Asset Impairment.

In 2008, we recorded an impairment charge of  $1.6 million  related  to  an  IRU
asset under a capital lease. The IRU asset  was no  longer in  use and we  have obtained alternative dark
fiber that serves the related facilities and  customers. There was no such charge  in 2009.

Gains on Purchases of Convertible Senior Notes.

In June 2007, we issued our 1.00% Convertible

Senior Notes (the ‘‘Notes’’) due June 15,  2027,  for an aggregate principal amount of $200.0 million.  In
2008, we purchased an aggregate of $108.0 million of face value  of the Notes for $48.6 million in cash
in a series of transactions. These transactions  resulted in gains totaling $23.1 million for the year ended
December 31, 2008. There were no purchases of Notes in the  year ended December  31, 2009.

Income tax provision (benefit). The income tax provision was $1.5 million for the year ended

December  31,  2008  and  an  income  tax  benefit  of  $1.2  million  was  recorded  for  the  year  ended
December 31, 2009. In the year ended  December 31,  2008, primarily due to the gains on the purchases
of our Notes, we became subject to the  alternative minimum  tax  in the United  States. Under  the
alternative minimum tax system, the ability  to  offset taxable income with the utilization of net operating
loss carryforwards is limited. The tax  provision for the year  ended  December 31, 2008 includes  income
taxes for the United States of approximately $0.6 million for federal alternative minimum tax and
approximately $0.9 million for state income taxes  (including approximately $0.5 million related  to  an
uncertain tax position). The net income tax benefit for  the year ended December 31, 2009  includes
income taxes for the United States of  approximately $0.3 million for state  income  taxes (including
approximately $0.1 million related to  penalties and interest on  an uncertain tax  position) offset by a tax
benefit of $1.5 million from the partial  reduction of a valuation allowance on  deferred tax assets
related to our Canadian operations.

Buildings On-net. As of December 31, 2008 and 2009 we  had  a total of 1,326 and  1,451 on-net

buildings connected to our network, respectively.

(2) Excludes equity-based compensation  expense of $10,176 and $17,548 in the  years  ended

period-to-period change of 29.4%.

Service Revenue. Our service revenue increased 16.1% from $185.7 million for  the year  ended

December 31, 2007 to $215.5 million for the year  ended December 31, 2008. The impact of  exchange
rates resulted in approximately $3.2 million of the $29.8 million increase in revenues. All foreign
currency comparisons herein reflect results for the  year ended December 31, 2008  translated at  the
average foreign currency exchange rates for the year ended  December 31, 2007. For the years ended
December 31, 2007 and 2008, on-net, off-net and non-core revenues  represented 79.0%, 17.3% and
3.7% and 81.7%, 16.1% and 2.2% of  our net service  revenues,  respectively.

Revenues from our corporate and net  centric customers represented 43.2%  and 56.8%  of our
service revenue, respectively, for the year  ended December 31, 2007 and represented 44.7% and 55.3%
of our service revenue, respectively, for the year ended  December 31,  2008. Revenues from  corporate
customers increased 20.2% from $80.1 million for  the year  ended  December 31, 2007 to $96.3  million
for the year ended December 31, 2008.  Revenues  from our net-centric customers increased 12.9% from
$105.5 million for the year ended December  31, 2007 to $119.2 million for the year ended
December 31, 2008. The difference in  the increase percentages  in net centric revenues  as compared  to
the increase in corporate revenues is  primarily attributed  to  a decline in the  average revenue  per  net
centric  customer connection from discounting. In June 2008,  we  introduced  additional volume and  term
based discounts to certain of our net  centric customers  in an effort to continue  to  gain market share
and  to continue to grow our revenues.

Our on-net revenues increased 20.1% from $146.6 million for the year ended  December 31, 2007

to $176.0 million for the year ended December 31, 2008. Our  on-net revenues  increased  as we
increased the number of our on-net customer connections by 26.4% from approximately 11,200 at

28

December 31, 2007 to approximately 14,100 at December 31, 2008.  On-net  customer connections
increased at a greater rate than on-net revenues due to a  decline  in the average revenue per on-net
customer connection. This decline is  partly attributed to a  shift in the  customer connection mix and  due
to volume and term based pricing discounts. Due to the increase  in the  size of our sales force,  we are
now able to focus not only on customers  who purchase high-bandwidth  connections, as  we have done
historically, but also on customers who purchase lower-bandwidth connections. We expect to continue
to focus  our sales  efforts on a broad mix of customers.  Additionally, on-net customers who cancel their
service from our installed base of customers, in general,  have greater average revenue per connection
than new customers. These trends resulted  in a reduction to our  average  revenue per on-net
connection.

Our off-net revenues increased 7.7%  from $32.1 million for the year  ended  December 31, 2007 to
$34.6 million for the year ended December 31, 2008.  Our  off-net customer  connections increased 1.8%
from approximately 2,990 at December  31, 2007 to approximately 3,040 at December 31, 2008.  Off-net
revenues increased at a greater rate than off-net customer connections due to an  increase in the
average revenue per off-net customer connection. Off-net  customers who cancel their service, in
general, have a lower average revenue  per  connection than new off-net customers who generally
purchase higher-bandwidth connections.

Our non-core revenues decreased 30.1%  from $6.9 million for the year ended  December 31,  2007

to $4.9 million for the year ended December 31, 2008. The number  of  our  non-core customer
connections declined 23.9% from approximately 800  at December 31,  2007 to approximately 600 at
December 31, 2008. We do not actively market these  acquired non-core  services and  expect that the  net
service revenue associated with them  will  continue  to  decline.

Network Operations Expenses. Our network operations expenses, excluding equity-based

compensation expense, increased 5.9%  from $87.5 million for the year ended  December 31,  2007 to
$92.7 million for the year ended December 31, 2008.  The increase  is primarily  attributable to an
increase in costs related to our network and facilities expansion activities  and an  increase in utilities
charges partly offset by the decline in  network  operations expenses associated  with the decline in our
non-core revenues. The impact of exchange rates resulted in  approximately  $1.4 million of the increase
in network operations expenses.

Selling, General, and Administrative Expenses  (‘‘SG&A’’). Our SG&A expenses, excluding equity-

based compensation expense, increased  21.0% from $52.0  million for the  year ended December  31,
2007 to $62.9 million for the year ended  December  31, 2008. SG&A expenses increased  primarily  from
the increase in salaries and related costs  required to support our expanding sales and  marketing efforts
and a $2.6 million increase in bad debt expense. The impact of exchange rates resulted  in
approximately $1.2 million of the increase  in SG&A expenses.

Equity-based Compensation Expense. Equity-based compensation expense is related to restricted

stock and stock options. The total equity-based compensation expense increased  72.1% from
$10.4 million for the year ended December 31, 2007  to  $17.9 million for the year ending December 31,
2008. In April 2007 and January 2008,  we issued approximately 1.0 million and  0.6 million shares,
respectively, of restricted stock to our  employees resulting in the  increase in equity-based  compensation
expense.

Depreciation and Amortization Expenses. Our depreciation and amortization expense decreased
4.6% from $65.6 million for the year ended December  31, 2007 to $62.6  million  for the  year  ended
December 31, 2008. The decrease is primarily due to the decline in depreciation  expense from fully
depreciated fixed assets more than offsetting depreciation  expense associated  with the increase  in
deployed fixed assets.

29

Asset Impairment.

In 2008, we recorded an impairment charge of  $1.6 million  related  to  an  IRU
asset under a capital lease. The IRU asset  was no  longer in  use and we  have obtained alternative dark
fiber that serves the related facilities and  customers.

Gains—lease obligations and asset sales.

In September 2007, we entered into a  settlement

agreement under which we were released from  our  obligation under  an abandoned facility lease
acquired in an acquisition. This settlement agreement resulted in  a gain of approximately $2.1  million.

Gains on Purchases of Convertible Senior Notes.

In June 2007, we issued our 1.00% Convertible

Senior Notes (the ‘‘Notes’’) due June 15,  2027,  for an aggregate principal amount of $200.0 million.  In
2008, we purchased an aggregate of $108.0 million of face value  of the Notes for $48.6 million in cash
in a series of transactions. These transactions  resulted in gains totaling $23.1 million for the year ended
December 31, 2008. There were no purchases of Notes in the  year ended December  31, 2007.

Income tax provision. The income tax provision was $1.5 million for  the year ended December 31,

2008. There was no income tax provision  for  the year  ended December  31, 2007.  In  the year  ended
December 31, 2008, primarily due to the  gains on the  purchases of our Notes, we became subject  to
the alternative minimum tax in the United  States.  Under the  alternative minimum tax system,  the
ability to offset taxable income with the  utilization of net  operating loss carryforwards is limited. The
tax provision  for the year ended December 31,  2008 includes income taxes  for the  United States of
approximately $0.6 million of federal alternative minimum tax and approximately  $0.9 million of state
income taxes (including approximately  $0.5  million related to an uncertain tax position).

Buildings On-net. As of December 31, 2007 and 2008 we  had  a total of 1,217 and  1,326 on-net

buildings connected to our network, respectively.

Liquidity and Capital Resources

In assessing our liquidity, management  reviews  and  analyzes our current cash  balances,  short-term

investments,  accounts  receivable,  accounts  payable,  accrued  liabilities,  capital  expenditure  and  operating
expense commitments, and required capital  lease, interest and debt payments and other obligations.

Cash Flows

Net Cash Provided By Operating Activities. Our primary sources of operating cash are receipts
from our customers who are billed on a  monthly  basis for our  services. Our  primary  uses of  operating
cash are payments made to our vendors, employees  and interest payments to our  note holders. Net
cash provided by operating activities  was $48.6  million  for the  year ended December  31, 2007 compared
to net cash provided by operating activities  of  $54.3 million for 2008. The increase  in cash provided  by
operating activities is due to an increase  in our operating profit partly offset by changes  in operating

30

assets and liabilities. Net cash provided  by  operating activities  was $54.3 million for the year ended
December 31, 2008 compared to net cash  provided by operating activities  of  $56.9 million for  the year
ended December 31, 2009. The increase  in cash provided by operating activities is  due  to  an increase in
our  operating profit partly offset by changes in operating assets and liabilities.

Net Cash Used In Investing Activities. Net cash used in investing activities was $30.9 million for

the year ended December 31, 2007, $32.5  million for the year ended December 31,  2008 and
$49.4 million for the year ended December 31, 2009.  Our  primary uses of investing cash during 2007
were $30.4 million for the purchases of property and equipment and $0.7  million for the purchases  of
short-term investments. Our primary  source of investing cash in 2007  was $0.3 million from the
proceeds of the sales of assets. Our primary use of investing  cash during  2008 was $33.5 million for the
purchases of property and equipment. Our primary sources of investing cash  in 2008 were $0.7  million
from the proceeds of short-term investments and  $0.2 million from the  proceeds of the  sales  of  assets.
Our primary use of investing cash during  2009 was $49.5 million for  the purchases of property and
equipment. Our primary sources of investing cash  in 2009 was $0.3  million  from the proceeds of the
sales of assets. The increases in purchases  of property and  equipment  from the year ended
December 31, 2007 to the year ended December 31, 2008 and from the  year ended December  31, 2008
to the year ended December 31, 2009  were  primarily due to  our increase in our network  expansion
activities including geographic expansion  and adding more buildings to our network including our
expansion into Mexico in 2009.

Net Cash Provided By (Used In) Financing Activities. Financing activities provided net cash of
$116.3 million for the year ended December  31, 2007.  Financing  activities used cash of $125.6  million
for the year ended December 31, 2008  and $23.5 for the year ended December 31, 2009.  Our primary
source of financing cash for the year ended  December  31,  2007 was $195.1 million of net  proceeds
from the issuance of our 1.00% Convertible Senior  Notes and $1.1 million of  proceeds from  the
exercises of stock options. Our primary  use of financing cash  for the year  ended December 31, 2007
was $59.9 million for the purchase of shares  of  our common stock, $10.2 million for the repayment of
our  Allied Riser convertible subordinated notes on their  June 15, 2007 maturity date  and $9.8 million
of principal payments under our capital  lease  obligations.  Our primary use of financing  cash for the
year ended December 31, 2008 was $59.3 million for  the purchase of shares of our common stock,
$48.6 million for repurchases of our  1.00% Convertible Senior Notes and $18.0  million of  principal
payments under our capital lease obligations. Our primary use of financing cash for the year ended
December 31, 2009 was $23.2 million  of  principal payments  under our capital lease  obligations and
$0.7 million for the purchases of shares  of  our common stock. Our primary source of financing cash for
the year ended December 31, 2009 was $0.3  million of proceeds from the exercises of stock options.
The increase in principal payments under  our  capital lease  obligations from the  year ended
December 31, 2007 to the year ended  December  31, 2008 and from the year  ended December 31,  2008
to the year ended December 31, 2009  was primarily  due to the increase  in our network expansion
activities including our expansion into  Mexico in 2009.

Indebtedness

Our total indebtedness, net of discount, at  December  31, 2009 was $175.9 million and our total
cash and cash equivalents and short-term  investments were $55.9 million. Our total indebtedness at
December 31, 2009 includes $109.7 million of capital  lease obligations for  dark  fiber primarily  under
15 -  25 year IRUs, of which approximately  $5.6 million  is considered a current liability.

Convertible Senior Notes

In June 2007, we issued our 1.00% Convertible Senior  Notes (the ‘‘Notes’’) due June 15, 2027, for
an aggregate principal amount of $200.0 million in  a private  offering for resale to qualified institutional
buyers pursuant to SEC Rule 144A. The Notes are unsecured  and bear interest at 1.00% per annum.

31

The Notes will rank equally with any future senior  debt and senior to any future subordinated debt and
will be effectively subordinated to all of  our subsidiary’s existing and future liabilities and  to  any
secured debt that we may issue to the  extent of  the value  of  the collateral. Interest  is payable  in cash
semiannually  in arrears on June 15 and December 15, of each year, beginning on December  15, 2007.
We  received proceeds of approximately $195.1 million after deducting the  original  issue discount of
2.25% and issuance costs.

In 2008, we purchased $108.0 million  of face value of our Notes  for $48.6 million in cash in a

series of transactions. These transactions  resulted in  a gain of  $23.1 million  for the  year ended
December 31, 2008. After these transactions there  is $92.0 million of  face value of our Notes
outstanding. We may purchase additional Notes.

The Notes are convertible into shares of  our common  stock  at  an  initial conversion price  of $49.18

per  share, or 20.3355 shares for each  $1,000 principal amount of  Notes, subject to adjustment  for
certain events as set forth in the indenture. Upon  conversion  of  the Notes, we  will have  the right to
deliver shares of our common stock, cash  or a combination of cash and shares of our common stock.
The Notes are convertible (i) during any  fiscal quarter  after the fiscal quarter ending September 30,
2007, if  the closing sale price of our  common  stock for  20 or  more trading days in a period of 30
consecutive trading days ending on the last  trading  day  of the immediately  preceding fiscal quarter
exceeds 130% of the conversion price in effect  on the last trading day of the  immediately preceding
fiscal quarter, or (ii) specified corporate transactions occur, or (iii)  the  trading  price of the Notes falls
below a certain threshold, or (iv) if we  call the  Notes for redemption, or  (v)  on or  after April 15,  2027,
until maturity. In addition, following specified corporate transactions, we will increase the  conversion
rate for holders who elect to convert  Notes in connection with such corporate  transactions, provided
that in no event may the shares issued upon conversion, as  a result of  adjustment or otherwise,  result
in the issuance of more than 35.5872 common shares  per  $1,000 principal amount. The Notes include
an ‘‘Irrevocable Election of Settlement’’ whereby we may choose, in  our sole  discretion,  and without
the consent of the holders of the Notes, to waive our right  to  settle the conversion feature in  either
cash or stock or in any combination,  at our option.

The Notes may be redeemed by us at any time after  June  20, 2014 at a redemption  price of 100%

of the principal amount plus accrued interest. Holders of  the Notes have the right  to  require us to
repurchase for cash all or some of their  Notes on June 15, 2014,  2017 and 2022 and upon the
occurrence of certain designated events at  a redemption price of 100% of the principal amount plus
accrued interest.

Allied Riser Convertible Subordinated Notes

Our $10.2 million 7.50% convertible subordinated notes were due  on June 15,  2007. These  notes

and accrued interest were paid on June  15,  2007 with  a portion of the proceeds  from the Notes.

Revolving line of credit

In October 2009, we entered into a $20.0 million revolving line of credit  facility with a  commercial

bank. Borrowings under the credit facility may  be  used  for  general corporate purposes,  acquisitions,
purchases of our common stock, and  purchases of our Notes. The credit facility  expires and all amounts
must be repaid on October 14, 2010.  Our ability to draw under the credit facility  is conditioned upon,
among other things, (i) the size of our  borrowing base, which  is comprised  of  our  accounts receivable
in the United States and Canada and amounts  we have on deposit  with the  bank; (ii)  our  ability  to
make the representations and warranties  contained in the  loan documents  on the  date of such
borrowing; and (iii) the absence of any  default  or event of default under its  loan documents.  The credit
facility has a floating interest rate of  one  month LIBOR plus 2.5% per annum, subject  to  a minimum
interest rate of 3.0% and has a commitment fee of 0.3%  per annum.

32

Our obligations under the credit facility are  secured by a  lien on the accounts,  general intangibles

and certain of our other assets and our  U.S. and Canadian operating subsidiaries. The credit facility
contains customary covenants, including, but not limited to, restrictions on us and our  U.S. and
Canadian operating subsidiaries’ ability  to  grant  liens or  security interests on assets subject  to  the banks
security interest and pay dividends. The  credit facility  requires the maintenance of a trailing four
quarter ratio of our funded debt to adjusted EBITDA  (as defined) of less than 3.0:1.0 and  a ratio of
our  adjusted EBITDA (as defined) less  dividends and capital  expenditures to its debt constituting
current maturities (excluding amounts  due under this revolving credit  facility) above 0.9:1  for the
quarters ended September 30, 2009 and December  31, 2009 and 1.2:1.0 for the quarters thereafter.  The
covenants also require us to maintain  a  minimum of $10.0  million to be deposited with the  commercial
bank. There have been no borrowings under the  revolving  facility and we have been  in compliance  with
the covenants.

Common Stock Buyback Program

In June 2007 we used approximately  $50.1 million of the net proceeds from our issuance of our
Notes to repurchase approximately 1.8  million  shares of our  common  stock.  In  August 2007, our board
of directors approved a $50.0 million  common stock buyback program.  In June 2008,  our  board of
directors approved an additional $50.0 million of purchases of  our common stock under  the buyback
program to occur prior to December 31,  2009. In the years ended  December 31,  2007, 2008 and 2009,
we purchased approximately 2.2 million, 4.4 million and 0.1 million shares of our common stock,
respectively, for approximately $59.9  million, $59.3  million and $0.7 million, respectively. All purchased
common shares were subsequently retired.

$254,999

(1) The Notes are assumed to be outstanding  until June  15, 2014 which is  the earliest put date  and

these amounts include interest and principal  payment obligations.

(2) These amounts include $232.5 million of operating lease, maintenance, building access and tenant

license agreement obligations, reduced by sublease agreements of $0.1 million.

(3) As of December 31, 2009, we had committed to additional dark fiber IRU lease  agreements

totaling approximately $47.0 million in future payments  for  fiber lease  and  maintenance services.
These amounts are included in unconditional  purchase obligations and  are to be paid  in periods of
up to 20 years beginning once the related fiber is  accepted.

Capital Lease Obligations. The capital lease obligations above were incurred in connection with

IRUs for inter-city and intra-city dark fiber  underlying  substantial portions of our network.  These
capital leases are presented on our balance sheet at the net present value of the  future minimum lease

33

payments, or $109.7 million at December  31, 2009. These  leases generally have  initial terms  of  15 to
20 years.

Letters of Credit. We are also party to letters of credit  totaling  $0.4 million at December 31, 2009.
These obligations are fully secured by our restricted investments, and as a result, are excluded  from the
contractual cash obligations above.

Future Capital Requirements

We believe that our cash on hand and cash generated from our operating activities will  be

adequate  to  meet  our  working  capital,  capital  expenditure,  debt  service,  and  other  cash  requirements  if
we execute our business plan.

Any future acquisitions or other significant unplanned costs  or  cash requirements may require  that

we raise additional funds through the  issuance of debt or equity. We cannot assure you that such
financing will be available on terms acceptable  to  us or our stockholders, or at all. Insufficient funds
may require us to delay or scale back the number of buildings  and markets that we add to our network,
reduce our planned increase in our sales and marketing efforts,  or  require us to otherwise alter our
business plan or take other actions that could  have a  material  adverse effect on our  business,  results of
operations and financial condition. If issuing equity securities raises additional funds, substantial
dilution to existing stockholders may result.

Off-Balance Sheet Arrangements

We do not have relationships with unconsolidated entities or financial partnerships,  such as  entities

often  referred to as structured finance or special purpose  entities, which would have  been established
for the purpose of facilitating off-balance sheet arrangements  or other  contractually narrow or  limited
purposes. In addition, we do not engage  in trading activities  involving  non-exchange traded contracts.
As such, we are not materially exposed to any financing, liquidity, market or credit risk that could arise
if we had engaged in these relationships.

Income taxes

Due to the uncertainty surrounding the  realization of our net  deferred tax asset, we have recorded

a valuation allowance for the substantial majority  of  our net deferred tax asset. As of December 31,
2009, we have combined net operating loss  carry-forwards  of approximately $1.1 billion.  This amount
includes federal and state net operating loss  carry-forwards in  the United  States  of approximately
$400 million, net operating loss carry-forwards  related  to  our  Canadian operations of approximately
$4 million and net operating loss carry-forwards related  to  our European operations of approximately
$680 million. Section 382 of the Internal Revenue Code in the United States limits the utilization  of
net operating losses when ownership changes, as defined  by that section, occur. We have performed an
analysis of our Section 382 ownership changes  and have determined that  the  utilization of certain of
our net operating loss carryforwards in the United  States may be limited.  This restricted  amount
includes the limitation on annual utilization related to the remaining $183 million of federal and  state
net operating loss carry-forwards of Allied Riser Communications Corporation that were acquired by us
via a 2002 merger. The net operating loss carryforwards in the  United States will expire,  if  unused,
between 2024 and 2030. The net operating loss  carry-forwards related to the  Canadian  operations
expire in 2027. The net operating loss carry-forwards related to our European operations include
$527 million that do not expire and $153 million that expire between  2010 and 2016.

Critical Accounting Policies and Significant Estimates

Our discussion and analysis of our financial condition and results of  operations are  based upon our

consolidated financial statements, which  have  been prepared in accordance  with accounting principles
generally accepted in the United States. The  preparation of  these financial statements requires us to
make estimates and judgments that affect  the reported amounts of assets,  liabilities, revenue and
expenses, and the related disclosure  of contingent  assets and  liabilities. We base our  estimates on
historical experience and on various  other  assumptions that are believed  to be reasonable under  the
circumstances, the results of which form the basis  for making judgments  about  the carrying values of
assets and liabilities that are not readily  apparent from  other sources. Actual results may  differ  from
these estimates under different assumptions  or conditions.

The accounting policies we believe to be most critical to understanding our financial results  and

condition or that require complex, significant  and  subjective management judgments are  discussed
below.

Revenue Recognition

We  recognize service revenue when the services are performed,  evidence of an arrangement  exists,
the fee is fixed and determinable and  collection is probable.  Service discounts  and incentives offered to
certain customers are recorded as a reduction  of revenue  when granted. Fees billed  in connection  with
customer  installations  are  deferred  and  recognized  ratably  over  the  longer  of  estimated  customer  life  or
contract term. We determine the estimated customer life using  a historical analysis  of customer
retention and contract terms. If our estimated customer life and contract terms increase,  we will
recognize installation revenue over a longer period. We expense the direct  costs associated  with sales as
incurred.

Allowances for Sales Credits and Unfulfilled Customer Purchase Obligations

We  have established allowances to account for sales credits and unfulfilled  contractual  purchase

obligations.

(cid:127) Our allowance for sales credits is recorded as a reduction to our service revenue to provide  for
situations when customers are granted a service termination adjustment  for amounts billed  in
advance or a service level agreement credit or discount. This allowance  is determined by actual
credits granted during the period and an estimate  of  unprocessed credits.

(cid:127) Our allowance for unfulfilled contractual  customer purchase obligations  is designed  to  account
for the possible non-payment of amounts  under agreements that we have with certain of  our
customers that place minimum purchase obligations  on them. Although we vigorously  seek
payments due pursuant to these purchase obligations,  we have  historically collected only a small
portion of these billed obligations. In  order  to  allow for  this,  we reduce  our gross service
revenue by the amount that has been invoiced to these customers. We reduce  this allowance and
recognize the related service revenue only upon the  receipt of cash payments in respect of these
invoices. This allowance is determined by the amount of unfulfilled contractual purchase
obligations invoiced to our customers and with  respect to which  we are continuing to seek
payment.

Valuation Allowances for Doubtful Accounts Receivable and Deferred Tax Assets

We  have established allowances associated with  uncollectible  accounts receivable and our deferred

tax assets.

(cid:127) Our valuation allowance for uncollectible accounts  receivable is  designed to account for the

expense associated with accounts receivable that we  estimate will not be collected. We assess the

35

adequacy of this allowance by evaluating general factors,  such as  the length of time individual
receivables are past due, historical collection experience, and changes in  the credit-worthiness of
our  customers. We also assess the ability of specific customers  to  meet  their financial  obligations
to us and establish specific allowances based on  the amount we expect to collect from these
customers. If circumstances relating to specific  customers change  or  economic  conditions change
such that our past collections experience  and  assessment of the economic environment  are no
longer appropriate, our estimate of  the recoverability of our trade  receivables could be impacted.

(cid:127) Our valuation allowance for our net deferred tax  asset reflects the  uncertainty surrounding the
realization of our net operating loss carry-forwards  and our other deferred tax assets. To reflect
for the uncertainty of future taxable  income  we have  recorded a valuation allowance for  the
significant majority of our net deferred tax asset. At each  balance  sheet  date, we assess the
likelihood that we  will be able to realize  our  deferred tax assets.  We consider all available
positive and negative evidence in assessing the need for a valuation allowance. As of
December 31, 2008, we determined that a  full valuation allowance against  our deferred tax
assets was necessary primarily due to the effect  of  historical operating losses.  At December 31,
2009, we concluded that it was more likely than  not  that  we would be able  to  realize certain of
our  deferred tax assets primarily as  a result  of  our estimate of  expected future  taxable income
related to our Canadian operations. Accordingly, we reversed the valuation allowance  recording
an income tax benefit of $1.5 million in the  year ended December 31, 2009. As  of December 31,
2009, we maintained a full valuation allowance against  our  other  deferred  tax assets consisting
primarily of net operating loss carryforwards.

Convertible Senior Notes

On January 1, 2009, we adopted Codification  Subtopic  470-20, Debt, ‘‘Debt with  Conversion and
Other Options’’ (‘‘ASC 470-20’’). ASC  470-20 clarifies the  accounting for convertible debt instruments
that may be settled in cash (including  partial cash settlement) upon conversion. ASC  470-20  requires
issuers to account separately for the liability and equity components of certain convertible  debt
instruments in a manner that reflects the  issuer’s nonconvertible debt borrowing  rate when interest cost
is recognized. ASC 470-20 requires bifurcation of a  component  of the debt, classification of that
component in equity and the amortization of the resulting discount on the debt to be recognized as
part of interest expense in our consolidated  statements  of  operations.

The adoption of ASC 470-20 affected the accounting for our 1.00%  Convertible Senior Notes (the

‘‘Notes’’). The retrospective application of this pronouncement affected the  period from  June  2007
(when the Notes were issued) through  December 31, 2008, including the  accounting for  the gains
resulting from our purchases of Notes in 2008. The adoption of ASC 470-20 required  us  to  estimate the
fair value of our Notes on the issuance date and on each purchase date. The fair value we  assigned to
the liability component of our Notes was determined using interest rates of similar debt  that  excluded a
conversion feature and then applying that effective interest rate to the cash flows associated with  the
Notes to calculate the present value.

Equity-based Compensation

We  grant options for shares of our common stock to our employees with a strike price equal  to  the
market value  at the grant date. We grant  shares  of restricted stock to our senior management  team and
to certain other employees. We determine  the fair  value of  grants of restricted  stock  by  the closing
trading price of our common stock on  the grant  date. Grants  of shares of restricted stock vest over
periods ranging from immediate vesting  to  over a four-year period.  Compensation expense  for all
awards is recognized ratably over the service period.

36

The accounting for stock option compensation expense requires us to make additional  estimates

and judgments that affect our financial  statements. These estimates include the following.

Expected Dividend Yield—We have never  declared  or paid dividends and have no plans  to  do  so
in the foreseeable future.

Expected Volatility—We use the historical volatility since  our June 2005 public  offering to estimate
expected volatility because less than 3%  of our fully  diluted shares  were publicly traded  before  that
date.

Risk-Free Interest Rate—We use the zero coupon U.S. Treasury rate during the quarter having a
term that most closely resembles the expected term of the option.

Expected Term of the Option—We estimate the expected life of the  option term  by  analyzing
historical stock option exercises and other  relevant  data.

Forfeiture Rates—We estimate the forfeiture rate  based on historical data with further
consideration given to the class of employees to whom the options or shares were granted.

Other Accounting Policies

We  record assets and liabilities under capital  leases at  the lesser  of the present value of the
aggregate future minimum lease payments  or the fair value of the assets  under lease. We establish the
number of renewal option periods used  in determining  the lease term, if any, based  upon our
assessment at the inception of the lease  of the  number of option periods that are reasonably  assured.
We  estimate the fair value of leased assets  using  market  data for similar assets.

We  capitalize the direct costs incurred  prior to an  asset being ready for service. These costs include
costs under the related construction  contract and the compensation costs of employees  directly involved
with construction activities. Our capitalization of these costs  is based upon estimates  of time  for our
employees involved in construction activities.

We  estimate our litigation accruals based upon our estimate  of the expected outcome after

consultation with legal counsel.

We  estimate our accruals for disputed leased  circuit obligations based upon the nature and age of

the dispute. Our network costs are impacted by the timing  and  amounts of  disputed circuit costs.  We
generally record these disputed amounts  when billed by the vendor and reverse these  amounts when
the vendor credit has been received or  the dispute  has otherwise been resolved.

We  estimate the useful lives of our property and equipment based upon historical usage with
consideration given to technological  changes and  trends in  the industry that could impact the asset
utilization. We establish the number  of  renewal option periods used in determining  the lease term, if
any, for amortizing leasehold improvements  based upon  our assessment at  the inception of the  lease of
the number of option periods that are  reasonably assured.

Recent  Accounting Pronouncements

Recent accounting pronouncements—to be adopted

In September 2009, the FASB issued  Accounting Standards Update  (‘ASU’’)  2009-13, Multiple
Element Arrangements. ASU 2009-13 addresses the determination of when the individual  deliverables
included in a multiple arrangement may  be treated as separate units  of accounting. ASU 2009-13 also
modifies the manner in which the transaction consideration  is allocated across  separately identified
deliverables and establishes definitions  for determining fair value  of elements in an arrangement.  This
standard must be adopted by us no later  than January 1, 2011 with  earlier adoption permitted. We are

37

currently evaluating the impact, if any, that  this standard update will  have on  our consolidated financial
statements.

ITEM 7A. QUANTITATIVE AND QUALITATIVE DISCLOSURES  ABOUT MARKET  RISK

We  are exposed to certain market risks. These risks, which  include interest  rate risk and foreign

currency exchange risk, arise in the normal course of business rather than from  trading activities.

Interest Rate Risk

Our cash  flow exposure due to changes  in interest rates related  to  our debt is limited as our Notes

have a fixed interest rate. The fair value  of the Notes may increase or decrease for various reasons,
including fluctuations in the market price of our common stock, fluctuations in market interest rates
and fluctuations in general economic  conditions. Based upon the quoted  market  price at  December 31,
2009, the fair value of our Notes was approximately $57.9 million.

Our interest income is sensitive to changes  in the general level of interest rates. However,  based
upon the nature and current level of our investments, which are  primarily  cash and cash equivalents, we
believe that there is no material interest  rate  exposure related to our investments.

Foreign Currency Exchange Risk

Our operations outside of the U.S. expose us  to  potentially unfavorable  adverse movements in
foreign currency rate changes. We have not entered into forward exchange contracts  related to our
foreign currency exposure. While we  record financial  results and assets and liabilities from  our
international operations in their local  currencies, these results  are reflected in our  consolidated
financial statements in U.S. dollars. Therefore, our  reported results  are  exposed  to  fluctuations in the
exchange rates between the U.S. dollar and  the local  currencies, in particular  the Euro and  the
Canadian  dollar.  In  addition,  we  fund  certain  cash  flow  requirements  of  our  international  operations  in
U.S. dollars. Accordingly, in the event  that  the local  currencies strengthen versus the U.S. dollar to a
greater extent than planned the revenues,  expenses and cash flow requirements associated with our
international operations may be significantly higher in U.S.-dollar terms than planned.

Report of Independent Registered Public  Accounting Firm

The Board of Directors and Stockholders of  Cogent  Communications Group, Inc.

We  have audited the accompanying consolidated balance sheets of Cogent Communications

Group, Inc. and subsidiaries (the ‘‘Company’’) as of December 31, 2008 and 2009, and the related
consolidated statements of operations, changes in  stockholders’ equity, and  cash flows for each of the
three years in the period ended December  31, 2009. Our audits also included the financial statement
schedule listed in the index at 15(a)  2. These financial  statements and schedule are  the responsibility of
the Company’s management. Our responsibility is to express an opinion  on these financial statements
and schedule based on our audits.

We  conducted our audits in accordance with the standards  of  the Public Company Accounting
Oversight Board (United States). Those  standards require that we  plan and perform the audit to obtain
reasonable assurance about whether  the  financial  statements are free  of material misstatement.  An
audit includes examining, on a test basis, evidence  supporting the amounts and disclosures  in the
financial statements. An audit also includes assessing the accounting  principles used  and significant
estimates made by management, as well as  evaluating the overall financial statement presentation. We
believe that our audits provide a reasonable  basis for our opinion.

In our opinion, the financial statements referred to above present fairly, in all material respects,

the consolidated financial position of  Cogent Communications Group, Inc. and subsidiaries at
December 31, 2008 and 2009, and the consolidated results  of their  operations and  their cash flows for
each  of the three years in the period  ended  December 31,  2009, in  conformity with U.S.  generally
accepted accounting principles. Also  in  our opinion, the  related financial  statement schedule, when
considered in relation to the basic financial statements taken as a whole,  presents  fairly in all material
respects the information set forth therein.

As discussed in Notes 1 and 4 to the  consolidated financial  statements,  the  Company changed its

method of accounting for convertible  debt instruments  with the adoption of  the guidance originally
issued in the Financial Accounting Standards Board’s (‘‘FASB’’) Staff Position No. Accounting
Principles Board 14-1,  Accounting for Convertible Debt Instruments That May  Be Settled in Cash upon
Conversion (Including Partial Cash Settlement) (‘‘FSP APB 14-1’’) (codified in FASB  Accounting
Standards Codification (‘‘ASC’’) Topic  470-20 Debt with Conversion and Other Options) effective
January 1, 2009. ASC 470-20 requires  retrospective  application for  all periods  presented  and
accordingly the Company has applied FSP APB 14-1 to all  years  presented.

We  also have audited, in accordance  with the standards of  the Public Company Accounting
Oversight Board (United States), Cogent Communications Group, Inc.’s internal control over financial
reporting as of December 31, 2009, based  on criteria established  in Internal Control-Integrated
Framework issued by the Committee of  Sponsoring  Organizations of the Treadway Commission and  our
report dated March 1, 2010 expressed an  unqualified opinion thereon.

Description of business

Cogent Communications Group, Inc.  (the ‘‘Company’’) is a Delaware  corporation and is

headquartered in Washington, DC. The  Company is a  facilities-based provider  of  low-cost, high-speed
Internet access and Internet Protocol  (‘‘IP’’)  communications services. The Company’s network  is
specifically designed and optimized to transmit data  using  IP. The Company delivers its services to
small and medium-sized businesses, communications service providers and other bandwidth-intensive
organizations in North America and Europe.

The Company offers on-net Internet access services  exclusively through its own  facilities,  which run

all the way to its customers’ premises. Because of its integrated  network architecture, the  Company is
not dependent on local telephone companies to serve  its on-net  customers. The  Company provides
on-net Internet access to certain bandwidth-intensive  users  such as  universities,  other  Internet service
providers, telephone companies, cable television  companies and  commercial content providers at speeds
up to 10 Gigabits per second. These  customers generally receive service in colocation facilities and the
Company’s data centers. The Company also offers Internet  access services in multi-tenant office
buildings typically serving law firms,  financial  services firms, advertising and marketing  firms and  other
professional services businesses. The  Company operates data centers throughout  North America  and
Europe that allow customers to collocate  their  equipment and access the  Company’s network.

In addition to providing on-net services,  the Company  also provides Internet  connectivity to

customers that are not located in buildings directly connected  to  its network. The Company serves
these off-net customers using other carriers’  facilities  to  provide the ‘‘last  mile’’ portion of the  link  from
its  customers’ premises to the Company’s network. The Company also provides  certain  non-core
services that resulted from acquisitions. The Company continues  to  support but  does not actively  sell
these non-core services.

Summary of Significant Accounting Policies

Principles of consolidation

The consolidated financial statements  have been prepared in accordance with United  States
generally accepted accounting principles  and include the  accounts of the Company and  all  of its  wholly
owned and majority-owned subsidiaries. All intercompany balances and  transactions have  been
eliminated in consolidation.

Use of estimates

The preparation of consolidated financial statements in conformity with United States generally
accepted accounting principles requires management to make  estimates and assumptions that affect  the
reported amounts of assets and liabilities and disclosures  of contingent assets  and liabilities at the date
of the consolidated financial statements and the reported amounts of  revenues  and expenses during the
reporting period. Actual results may differ from these estimates.

DECEMBER 31, 2007, 2008 and 2009

1. Description of the business and summary of significant accounting policies:  (Continued)

Revenue recognition and allowance for  doubtful accounts

The Company’s service offerings consist of telecommunications services provided under

month-to-month or annual contracts. Fixed fees are billed monthly in  advance  and usage fees are billed
monthly in arrears. Net revenues from  telecommunication services are  recognized when the services are
performed, evidence of an arrangement  exists, the fee is fixed and determinable and collection is
probable. The probability of collection  is  determined  by  an analysis of a new customer’s credit  history
and historical payment patterns for existing customers. Service discounts  and  incentives related to
telecommunication services are recorded  as  a reduction  of  revenue  when granted.  Fees billed in
connection  with  customer  installations  are  deferred  and  recognized  ratably  over  the  longer  of  the
contract term or the estimated customer  life  which is determined  by a historical analysis of customer
retention  and  the  contract  term.  The  Company  expenses  the  direct  costs  associated  with  sales  as
incurred.

The Company invoices certain customers  for amounts  contractually due for unfulfilled minimum
contractual obligations and recognizes  a  corresponding  sales allowance equal  to  the amount invoiced
resulting in the recognition of no net  revenue at  the time  the customer is billed. The Company
vigorously seeks payment of these amounts.  The Company  recognizes net revenue  as these billings are
collected in cash.

The Company establishes an allowance for doubtful accounts  and other  sales  credit adjustments.

Allowances  for  sales  credits  are  established  through  a  reduction  of  revenue,  while  allowances  for
doubtful accounts are established through a charge  to  selling, general, and administrative  expenses. The
Company assesses the adequacy of these reserves  by  evaluating  general  factors, such  as the length of
time individual receivables are past due, historical collection experience, and  changes in the  credit
worthiness of its customers. The Company also assesses  the ability of specific  customers  to  meet their
financial  obligations  and  establishes  specific  allowances  related  to  these  customers.  If  circumstances
relating to specific customers change or economic conditions change  such that the Company’s past
collection experience and assessment  of the  economic environment are  no longer appropriate, the
Company’s estimate of the recoverability of its trade receivables could  be  impacted.

Network operations

Network operations include costs associated with service delivery, network management,  and
customer support. This includes the costs  of  personnel and related operating  expenses associated  with
these activities, network facilities costs, fiber and equipment  maintenance fees, leased circuit  costs, and
access fees paid to building owners. The Company estimates its accruals for any  disputed leased circuit
obligations based upon the nature and age of the dispute.  Network  operations costs are impacted by
the timing and amounts of disputed circuit costs. The Company generally records these disputed
amounts when billed by the vendor and reverses these amounts when the vendor credit  has been
received or the dispute has otherwise  been  resolved. The Company  does not allocate depreciation and
amortization expense to its network operations expense.

Foreign currency translation adjustment and comprehensive income  (loss)

The consolidated financial statements  of Cogent Canada and Cogent Europe are translated into

U.S. dollars using the period-end foreign currency exchange rates  for assets and liabilities and the
average foreign currency exchange rates  for revenues and  expenses. Gains and  losses on  translation of
the accounts of the Company’s non-U.S. operations are  accumulated  and  reported as  a component of
other comprehensive loss in stockholders’ equity. The Company’s  only components of ‘‘other
comprehensive loss’’ are currency translation adjustments for all  periods presented.

Financial instruments

The Company considers all highly liquid investments  with an original maturity of three months or

less  at purchase to be cash equivalents.  The Company determines the  appropriate  classification  of its
investments at the time of purchase and  evaluates  such designation at each balance sheet  date.

At December 31, 2008 and 2009, the  carrying amount of  cash and cash equivalents,  short-term

investments, accounts receivable, prepaid  and other  current assets,  accounts payable,  and accrued
expenses approximated fair value because  of the short-term nature  of these  instruments. The Company
measures its cash equivalents at fair value based  upon quoted (Level 1) market prices and  at amortized
cost, which approximates fair value. Based upon  the quoted (Level 1) market price  at December 31,
2009, the fair value of the Company’s  $92.0 million convertible senior  notes was approximately
$57.9 million.

Short-term investments

Short-term investments consist of certificates of deposit  with original maturities  beyond three
months, but less than twelve months. Such short-term investments are carried at amortized cost, which
approximates fair value due to the short period of  time to maturity.

The Company was party to letters of  credit totaling  approximately  $0.9 million  as of December 31,

2008  and  $0.4  million  as  of  December  31,  2009.  These  letters  of  credit  are  secured  by  investments
totaling approximately $1.2 million at  December 31,  2008 and  $0.5 million as of  December 31,  2009,
that are restricted  and included in short-term investments and other assets.

Credit risk

The Company’s assets that are exposed to credit  risk  consist of its cash and  cash equivalents,
short-term investments, other assets and  accounts receivable. As  of  December 31,  2008 and 2009, the
Company’s cash equivalents were invested in  demand deposit accounts, overnight investments and
money market funds. The largest individual investment amount was $26.1 million  at December 31, 2008
(money market fund) and $11.1 million at December 31, 2009 (demand deposit  account). The
Company places its cash equivalents and  short-term investments in instruments  that  meet high-quality
credit standards as specified in the Company’s  investment policy  guidelines. The covenants  included in
Company’s revolving line of credit facility  with a  bank requires a minimum  of $10.0 million to be
deposited with that bank. Accounts receivable  are due from customers located in  major metropolitan
areas in the United States, Europe and  Canada. Receivables from the  Company’s net  centric
(wholesale) customers are subject to a higher  degree  of credit  risk than other customers.

Property and equipment

Property and equipment are recorded at cost and depreciated  once deployed using  the straight-line

method over the estimated useful lives  of the assets.  Useful lives are determined  based on  historical
usage with consideration given to technological changes and trends in the industry that could impact
the asset utilization. System infrastructure costs include the capitalized compensation costs of
employees directly involved with construction activities  and costs incurred by third  party contractors.
Assets  and liabilities under capital leases  are  recorded at  the lesser of the present value of the
aggregate future minimum lease payments  or the fair value of the assets  under lease. Leasehold
improvements  include  costs  associated  with  building  improvements.  The  Company  determines  the
number of renewal option periods, if  any,  included in  the lease term for purposes of amortizing
leasehold improvements based upon its assessment  at the  inception of the lease  of the number of
option periods that are reasonably assured.  Expenditures  for maintenance and repairs  are expensed as
incurred.

Depreciation and amortization periods are  as follows:

3 to 7 years
5 to 10 years

Long-lived assets

The Company’s long-lived assets include  property  and  equipment  and identifiable intangible assets.

These long-lived assets are reviewed  for impairment whenever events or changes in  circumstances
indicate that the carrying amount may not be recoverable. Impairment is determined by comparing the
carrying  value of these long-lived assets  to management’s probability weighted estimate of the future
undiscounted cash flows expected to result  from the use of the assets.  In  the event an impairment
exists, a loss is recognized based on the amount by  which the  carrying value exceeds the fair  value of
the asset, which would be determined  by using  quoted market prices or valuation  techniques such as
the discounted present value of expected  future cash  flows, appraisals, or  other  pricing  models.  In  the
event there are changes in the planned use of the Company’s long-term assets  or the Company’s
expected future undiscounted cash flows are reduced significantly, the  Company’s assessment of its
ability to recover the carrying value of  these assets  could  change.

Asset retirement obligations

The fair value of a liability for an asset retirement  obligation is recognized in the  period in which
it is incurred  if a reasonable estimate of fair value can be made. The associated asset  retirement costs

are capitalized as part of the carrying amount of the  long-lived asset. The Company records  changes  in
the liability for an asset retirement obligation due to passage of time using the  effective interest  rate
method. The interest rate used to measure that change  is the credit-adjusted risk-free rate  that  existed
when the liability was initially measured.

Equity-based compensation

The Company recognizes compensation expense for its share-based payments granted to its
employees based on their grant date  fair values  with the expense being recognized over the requisite
service period. See Note 8 for additional  information.

Income taxes

The Company’s deferred tax assets or  liabilities are computed based  upon the differences between

financial statement and income tax bases of  assets and liabilities using the enacted  marginal  tax rate.
Deferred income tax expense or benefits are based upon the changes in the assets  or liability from
period to period.

Management determines whether a tax position is more likely  than not to be sustained  upon
examination based on the technical merits of  the position.  Once it  is determined that a  position  meets
this  recognition threshold, the position  is measured to determine the amount of benefit to be
recognized in the financial statements.  The Company’s policy  is to recognize interest and penalties
accrued on any unrecognized tax benefits  as a  component of income tax expense.

The Company or one of its subsidiaries  files income tax returns in  the U.S.  federal jurisdiction and

various state and foreign jurisdictions.  The Company  is subject  to  U.S. federal tax and  state tax
examinations for years from 2005 to 2009. The Company is subject to tax examinations in its foreign
jurisdictions generally for years from 2000  to  2009. Management does not believe there  will be any
material changes in its unrecognized  tax  positions over  the next 12 months.

Basic and diluted net loss per common share

Basic earnings per share (‘‘EPS’’) excludes dilution for common stock equivalents and is computed
by dividing net income or (loss) available  to common stockholders  by the  weighted-average number of
common shares outstanding for the period. Diluted EPS is based on  the weighted-average number of
shares of common stock outstanding  during  each period,  adjusted for the effect of  common stock
equivalents, if dilutive.

Shares of restricted stock are included  in the computation  of  basic EPS  as they  vest and are

included in diluted EPS, to the extent  they are  dilutive,  determined using the treasury  stock method. As
of December 31, 2007, 2008 and 2009, 1.2 million, 1.7 million and 0.4 million unvested shares of
restricted common stock, respectively, are not  included in  the computation of  diluted loss per share,  as
the effect would be anti-dilutive.

Using the ‘‘if-converted’’ method, the shares issuable  upon conversion of  the Company’s 1.00%
Convertible Senior Notes (the ‘‘Notes’’) were  anti-dilutive for the years ended December  31, 2007, 2008
and 2009. Accordingly, the impact has been excluded  from  the EPS computations. The Notes are

convertible into shares of the Company’s common stock at  an initial conversion price of $49.18  per
share, yielding 4.1 million common shares, as of  December  31, 2007 and 1.9 million shares at
December 31, 2008 and 2009, subject to certain adjustments set forth  in the indenture.

The Company computes the dilutive  effect of outstanding  options using  the treasury stock  method.
For the years ended December 31, 2007,  2008 and 2009 options to purchase 1.1 million, 1.1  million  and
0.4 million shares of common stock,  respectively, at  weighted-average exercise  prices of $5.75,  $5.65 and
$12.59 per share, respectively, are not  included in the computation  of diluted loss per share  as the
effect would be anti-dilutive.

Recent accounting pronouncements—adopted

In June 2009, the Financial Accounting Standards Board (‘‘FASB’’) issued  FASB ASC  105,
‘‘Generally Accepted Accounting Principles’’ which establishes  the FASB Accounting Standards
Codification (‘‘ASC’’) as the sole source of authoritative generally accepted  accounting principles.
Pursuant to the provisions of FASB ASC  105, the Company has updated references to GAAP in  its
financial statements. The adoption of FASB ASC 105 did not impact the  Company’s financial position
or results of operations.

On  January  1,  2009,  the  Company  adopted  the  provisions  of  Accounting  Standards  Codification

(‘‘ASC’’) ASC 470-20, Debt, ‘‘Debt with Conversion  and Other  Options’’ (‘‘ASC  470-20’’). ASC 470-20
clarifies the accounting for convertible debt instruments  that may be settled in  cash (including partial
cash settlement) upon conversion. ASC  470-20 requires issuers  to  account separately for the liability
and equity components of certain convertible debt instruments in a manner that reflects the  issuer’s
nonconvertible debt borrowing rate when  interest cost is recognized. ASC 470-20 requires bifurcation of
a component of the debt, classification  of  that component in equity  and  the  amortization of the
resulting discount on the debt to be  recognized as part of interest  expense in  the Company’s
consolidated statements of operations.

ASC 470-20 requires retrospective application for all periods presented for instruments that were

outstanding during any of the periods presented in  the consolidated financial statements. The adoption
of ASC 470-20 affected the accounting for the  Company’s Notes. The retrospective  application  of this
pronouncement affected the period from June 2007  (when the Notes were issued)  through
December 31, 2008.

The following table sets forth the effect of the  retrospective  application of  ASC 470-20  on certain

previously reported line items (in thousands,  except per share data):

The Company has adopted the provisions of  ASC 820 ‘‘Fair Value  Measurements  and Disclosures’’

(‘‘ASC  820’’). ASC 820 defines fair value, establishes  a framework for  measuring fair value  in
accordance with generally accepted accounting principles, and expands  disclosures about fair value
measurements. The adoption of the various  provisions of ASC 820  did not  have a material effect on
the Company’s consolidated financial position, results  of operations  or cash flows.

The Company evaluates its freestanding financial  instruments, or embedded features, under the

provisions of ASC 815-40 ‘‘Derivatives and  Hedging—Contracts in Entity’s Own Equity’’
(‘‘ASC  815-40’’) to determine if they  are  considered indexed  to  its  stock. If the instrument  or embedded
feature is not eligible for equity classification it would be classified as an asset  or liability and
remeasured at fair value through earnings. The Company has determined  that  its  embedded  conversion
features are considered indexed to its stock.  As a result, the adoption  of ASC 815-40 did  not  have a
material impact on the Company’s consolidated financial position, results  of operations,  or cash  flows.

1. Description of the business and summary of significant accounting policies:  (Continued)

The Company accounts for its acquisitions  under the provisions of ASC 805 ‘‘Business

Combinations’’ (‘‘ASC 805’’). ASC 805  establishes  principles and requirements for  how an acquirer
recognizes and measures in its financial statements  the identifiable  assets acquired, the liabilities
assumed, and any noncontrolling interest in the  acquiree  and recognizes and measures  the goodwill
acquired in the business combination or a gain from a bargain purchase. ASC 805 also sets forth the
disclosures required to be made in the  financial statements to evaluate the nature  and financial effects
of the business combination. There have been no material acquisitions by the Company since
January 1, 2009 (the ASC 805 adoption  date), as a  result there has been  no material impact related to
the Company’s adoption of ASC 805.

ASC 855 ‘‘Subsequent Events’’ establishes general standards  of  accounting for  and disclosure of
events that occur after the balance sheet date but  before  financial statements are issued. The  Company
has adopted the provisions of ASC 855.  The adoption of ASC 855 did not have  a material effect on  the
Company’s consolidated financial position, results  of  operations or cash  flows.

Convertible Senior Notes

In June 2007, the Company issued its  Notes for an aggregate principal amount of $200.0 million in

a private offering for resale to qualified  institutional buyers pursuant to SEC Rule  144A. The Notes
mature on June 15, 2027, are unsecured,  and bear interest at 1.00% per annum. The Notes will rank
equally  with any future senior debt and  senior to any future subordinated debt and  will be effectively
subordinated to all existing and future  liabilities of the Company’s  subsidiaries and to any secured  debt
the Company may issue, to the extent of  the value of the  collateral. Interest is  payable in  cash
semiannually  in arrears on June 15 and December 15, of each year, beginning on December  15, 2007.
The Company received net proceeds  from the  issuance  of the Notes  of approximately $195.1 million,
after deducting the original issue discount of 2.25% and issuance costs.  The  discount and other
issuance costs are being amortized to interest expense  using the effective  interest method  through
June 15, 2014, which is the earliest put  date.

Conversion Process and Other Terms of the Notes

The Notes are convertible into shares of  the Company’s common stock  at an  initial conversion

price of $49.18 per share, or 20.3355 shares  for each  $1,000 principal amount of Notes, subject to
adjustment for certain events as set forth in  the indenture. Depending upon the price  of  the Company’s
common stock at the time of conversion,  holders of  the Notes will receive additional  shares of the
Company’s common stock. Upon conversion  of the Notes, the Company will  have the right to deliver

shares of its common stock, cash or a  combination of cash and shares  of its common stock. The Notes
are convertible (i) during any fiscal quarter after the fiscal quarter ending September  30, 2007, if the
closing sale price of the Company’s common stock for 20 or more  trading  days in a  period of  30
consecutive trading days ending on the last  trading  day  of the immediately  preceding fiscal quarter
exceeds 130% of the conversion price in effect  on the last trading day of the  immediately preceding
fiscal quarter, or (ii) specified corporate transactions occur, or (iii)  the  trading  price of the Notes falls
below a certain threshold, or (iv) if the  Company calls the Notes for redemption,  or (v) on  or after
April 15, 2027, until maturity. In addition,  following specified corporate transactions,  the Company will
increase the conversion rate for holders who elect to convert notes in connection  with such  corporate
transactions, provided that in no event may  the shares  issued  upon conversion, as  a result of  adjustment
or otherwise, result in the issuance of  more than 35.5872 common  shares per $1,000  principal amount.
The Notes include an ‘‘Irrevocable Election of Settlement’’ whereby  the Company may  choose, in its
sole discretion, and without the consent of the holders  of  the Notes, to waive  its  right to settle the
conversion feature in either cash or stock or  in any combination at  its  option. The  Notes may  be
redeemed by the Company at any time after June 20,  2014 at a redemption price of 100% of the
principal amount plus accrued interest. Holders of the Notes have the  right to require the  Company to
repurchase for cash all or some of their  notes on June 15, 2014,  2017 and 2022 and upon  the
occurrence of certain designated events at  a redemption price of 100% of the principal amount plus
accrued interest.

Registration Rights

Under the terms of the Notes, the Company is  required to use reasonable efforts to file  and
maintain a shelf registration statement  with the  SEC covering  the resale  of the Notes and the common
stock issuable on conversion of the Notes. If the Company fails to meet these  terms, the Company will
be required to pay special interest on  the  Notes  in the amount of 0.25% for  the first 90 days  after the

interest of 0.25% per annum will accrue  in  the event of  default, as  defined in the indenture.  The
Company filed a shelf registration statement registering the Notes and common stock issuable upon
conversion of the Notes in July 2007.

As a result of the adoption of ASC 470-20,  the Company was required to separately account  for

the debt and equity components of the  Notes in  a manner that reflects its nonconvertible debt
(unsecured debt) borrowing rate when  interest  expense is  recognized.  The  debt and equity  components
for the Notes were as follows (in thousands):

At each balance sheet date, the Company assesses the likelihood that it  will be able to realize its

deferred tax assets. The Company considers all available positive  and negative  evidence in assessing  the
need for a valuation allowance. As of December 31, 2008,  the Company  determined  that  a full
valuation allowance against its deferred tax assets was necessary primarily due to the effect of historical
operating losses. At December 31, 2009, the  Company concluded that it was more  likely than not that
it would be able to realize certain of its  deferred tax  assets primarily as a  result of expected future
taxable income related to its Canadian operations. Accordingly,  the  Company reversed a  portion of its
valuation  allowance  related  to  these  deterred  tax  assets  and  recorded  an  income  tax  benefit  of
$1.5 million in the year ended December  31, 2009. As of December  31, 2009,  the Company maintained
a full valuation allowance against its  other deferred tax assets consisting primarily of net operating loss
carryforwards.

As of December 31, 2009, the Company has combined net operating  loss carry-forwards  of
approximately $1.1 billion. This amount  includes federal and state net operating loss carry-forwards  in
the  United  States  of  approximately  $400  million,  net  operating  loss  carry-forwards  related  to  its
Canadian operations of approximately  $4  million and  net operating  loss carry-forwards  related to its
European operations of approximately $680 million.  Section 382 of the Internal Revenue Code  in the
United States limits the utilization of  net operating losses when ownership  changes, as defined by that
section, occur. The Company has performed an  analysis of its Section  382 ownership changes and has
determined that the utilization of certain of  its net  operating loss carryforwards  in the United States
may be limited. This restricted amount  includes the  limitation on annual  utilization related  to  the
remaining $183 million of federal and state net  operating loss carry-forwards  of  Allied Riser
Communications Corporation that were  acquired by the Company via  merger in 2002. The net
operating loss carryforwards in the United States will expire, if  unused, between 2024  and 2030. The
net operating loss carry-forwards related to the  Canadian operations  expire in 2027. The net  operating
loss carry-forwards related to the European  operations include  $527 million that do not expire and
$153 million that expire between 2010  and 2016.

In the normal course of business the  Company takes positions  on  its  tax returns that may  be
challenged by taxing authorities. The Company evaluates  all uncertain  tax  positions  to  assess whether
the position will more likely than not  be  sustained upon  examination.  If the Company determines that

the tax position is more likely than not to be sustained, the  Company records the  amount  of the benefit
that is more likely than not to be realized when  the tax  position  is settled.  This liability is included  in
other long-term liabilities in the accompanying  balance  sheets and  was  $0.5 million as of December 31,
2008 and $0.6 million as of December 31,  2009. The Company does  not expect the final resolution of
tax examinations to have a material impact on the Company’s  financial  results.

Capital leases—fiber lease agreements

The Company has entered into lease agreements  with several providers for  dark  fiber primarily

under 15 - 20 year IRUs with additional  renewal terms. These IRUs connect the  Company’s
international backbone fibers with the multi-tenant office buildings,  carrier  neutral data centers  and the
customers served by the Company. Once  the Company has  accepted the related fiber route, leases that
meet the criteria for treatment as capital leases are recorded as  a  capital lease obligation  and an  IRU
asset. The future minimum payments under  these agreements are as follows  (in  thousands):

6. Commitments and contingencies: (Continued)

Capital lease obligation amendments

In 2004, Cogent Spain negotiated modifications to an IRU capital lease  and  note obligation with a

vendor. The modified note was interest free and  included nineteen  equal quarterly installment
payments beginning in 2005 of $0.3 million  and a  final  payment of $5.9 million due in January 2010. In
December 2009, Cogent Spain further  amended the  note obligation. The  modified  note accrues interest
at the lower of 2% or Euribor and includes an initial  payment of $0.6  million  in January 2010  followed
by eleven semi-annual installment payments  of $0.5 million.

Current and potential litigation

The Company is involved in disputes  with certain  telecommunications  companies. The total
amount claimed by these vendors is approximately  $0.3 million. The Company  does not believe  any of
these amounts are owed to these providers and intends to vigorously defend its position  and believes
that it has adequately reserved for any  potential liability.

The Company has been made aware of several other companies in  its own and  in other industries
that use the word ‘‘Cogent’’ in their  corporate names.  One  company has informed  the Company that it
believes the Company’s use of the name ‘‘Cogent’’ infringes on its intellectual  property rights in that
name. If such a challenge is successful,  the Company could be required to change its name and lose the
value associated with the Cogent name in its markets. Management does not believe such a challenge,
if successful, would have a material impact on  the Company’s business, financial condition or  results of
operations.

In the normal course of business the  Company is  involved in  other legal activities and  claims.
Because such matters are subject to many uncertainties and the outcomes are  not  predictable with
assurance, the liability related to these legal  actions and claims  cannot be determined with certainty.
Management does not believe that such claims  and actions will  have a material impact on the
Company’s financial condition or results  of operations.

Operating leases, maintenance and tenant  license agreements

The  Company  leases  office  space,  network  equipment  sites,  and  other  facilities  under  operating
leases. The Company also enters into building access  agreements with  the landlords of multi-  tenant
office buildings. The Company pays fees  for  the maintenance of its leased dark fiber and in certain

Expenses related to these arrangements  were $40.5 million in 2007,  $44.9 million in 2008  and

$49.0 million in 2009.

The Company has sublet certain office  space and facilities. Future minimum payments under

sub-lease agreements are approximately  $0.1 million.

Unconditional purchase obligations

Unconditional purchase obligations for equipment and services totaled  approximately $9.2 million

at December 31, 2009 and are expected  to  be  fulfilled within one year. As  of  December 31, 2009 the
Company had committed to additional dark fiber  IRU lease agreements totaling approximately
$47.0 million in future payments for  fiber  lease and  maintenance payments to be paid over periods of
up to 20 years. These obligations begin  when the  related fiber is accepted, which is expected to occur
in 2010. Future minimum payments under  these obligations are approximately, $7.5 million,
$2.6 million, $2.6 million, $2.6 million, and $2.6  million for the years ending December  31, 2010 to
December 31, 2014, respectively, and  approximately $29.1  million,  thereafter. In June  2009, the
Company entered into an amended equipment  purchase  agreement with  a vendor.  Under  the
agreement, and prior agreements, the Company will be required to purchase equipment totaling
approximately $23.2 million through  2011.

Defined contribution plan

The Company sponsors a 401(k) defined contribution plan that, effective in August 2007,  provides

for a Company matching payment. The  Company matching  payments for 2008 and 2009  were
approximately $0.3 million and $0.3 million,  respectively and were paid in  cash.

6. Commitments and contingencies: (Continued)

Revolving line of credit

In October 2009, the Company entered  into  a $20.0 million revolving line of credit  facility  with a

bank. Borrowings under the facility may be used for  general  corporate purposes, acquisitions, purchases
of the Company’s common stock, and purchases of the Company’s convertible  notes. The facility
expires and all amounts must be repaid  on October 14, 2010.  The Company’s ability to draw  under the
revolving facility is conditioned upon,  among  other things,  (i) the size  of  the Company’s borrowing
base, which is comprised of the Company’s accounts  receivable in  the United States  and Canada, and
amounts the Company has on deposit  with  the bank;  (ii) the  Company’s ability to make the
representations and warranties contained in the  loan documents on the date of such  borrowing; and
(iii) the absence of any default or event of default  under its loan  documents. The revolving facility  has
a floating interest rate of one month  LIBOR plus 2.5% per annum, subject to a  minimum interest rate
of 3.0% and has a commitment fee of  0.3% per annum.

The Company’s obligations under the  revolving facility are  secured by a  lien on the accounts
receivable, general intangibles and certain  other assets of the Company and its U.S. and  Canadian
operating subsidiaries. The revolving  facility contains  customary covenants,  including, but not limited to,
restrictions on the Company and its U.S.  and Canadian operating subsidiaries’  ability to grant liens or
security interests on assets subject to the banks security interest  and  pay  dividends.  The  revolving
facility requires the maintenance of a  trailing four quarter ratio  of  the Company’s funded debt  to
adjusted EBITDA (as defined) of less  than 3.0:1.0 and a ratio  of the Company’s  adjusted EBITDA  (as
defined) less dividends and capital expenditures to its debt constituting current  maturities (excluding
any amounts due under the revolving  credit facility)  above 0.9:1 for the quarters ended September 30,
2009 and December 31, 2009 and 1.2:1.0 for  the quarters thereafter.  The covenants also  require the
Company’s to maintain a minimum of $10.0  million  to  be  deposited with  the bank. There have been no
borrowings under the revolving facility  and the  Company was in  compliance with these  covenants.

7. Stockholders’ equity:

Authorized shares

The Company has 75.0 million shares  of  authorized  $0.001 par  value common stock  and 10,000

authorized but unissued shares of $0.001  par value preferred  stock. The holders of common  stock  are
entitled to one vote per common share  and, subject to any rights of any series of preferred stock,
dividends may be declared and paid  on the  common  stock when  determined by the Company’s Board
of Directors.

Common Stock Buybacks

In August 2007, the Company’s board of directors  approved  a  $50.0 million common stock buyback

program (the ‘‘Buyback Program’’). In  June 2008, the  Company’s board  of directors approved an
additional $50.0 million of purchases  of the Company’s  common stock under  the Buyback Program to
occur prior to December 31, 2009. In  the  years  ended December 31, 2008 and 2009, the  Company
purchased approximately 4.4 million  and 0.1 million shares of its common stock, respectively, for
approximately $59.3 million and $0.7  million,  respectively, under the Buyback Program. These common
shares were subsequently retired.

7. Stockholders’ equity: (Continued)

Allied Riser Warrants

In connection with the February 2002  merger with Allied Riser, the Company assumed warrants
issued by Allied Riser that could convert  into  approximately 5,200  shares of  the Company’s  common
stock. During the year ended December  31, 2009,  these warrants with a  carrying amount of
approximately $0.8 million expired resulting in  a reduction  to  warrants and a  corresponding  increase to
additional paid-in capital.

8. Stock option and award plan:

Incentive Award Plan

The Company has an award plan, the 2004 Incentive  Award  Plan, as amended (the ‘‘Award Plan’’),

under which grants of stock and options  are  made,. Stock options granted under the Award Plan
generally vest over a four-year period  and  have a term of ten years. Grants  of shares of  restricted stock
granted under the Award Plan vest over periods  ranging  from immediate vesting to over a four-year
period. Awards with graded vesting terms are recognized  on a straight  line basis. Certain option and
share grants provide for accelerated vesting if there is a change in control,  as defined. For grants of
restricted stock, when an employee terminates prior to full  vesting  the employee retains their vested
shares and the employees’ unvested shares are  returned  to the plan.  For grants of options for common
stock, when an employee terminates  prior to full vesting the employee may elect to exercise their
vested options for a period of ninety  days  and any unvested options are returned to the plan.
Compensation expense for all awards is recognized ratably  over the service period. Shares issued to
satisfy awards are provided from the Company’s authorized shares. As of December 31, 2009,  of the
5.8 million authorized shares under the Award Plan there  were  a  total  of 0.2 million shares available
for grant.

The  accounting  for  stock  option  compensation  expense  requires  the  Company  to  make  estimates

and judgments that affect its financial statements. These  estimates  include  the following.

Expected Dividend Yield—The Company has never  declared or paid dividends and has no plans to
do so in the foreseeable future.

Expected Volatility—The Company uses its historical volatility since  its  June 2005  public offering
to estimate expected volatility because less than 3% of  its fully diluted shares were publicly traded
before that date.

Risk-Free Interest Rate—The Company uses the zero  coupon U.S. Treasury  rate during the
quarter having a term that most closely  resembles the expected  term of the  option.

Expected Term of the Option—The Company  estimates the  expected life  of  the option  term by
analyzing historical stock option exercises and  other relevant data.

Forfeiture Rates—The Company estimates  its forfeiture  rate  based on historical data with further
consideration given to the class of employees to whom the options or shares were granted.

9. Related party transactions:

Office lease and equipment purchases

The Company’s headquarters is located in an  office building owned by a partnership

(6715 Kenilworth Avenue Partnership).  The two owners of the partnership are the  Company’s Chief
Executive Officer, who has a 51% interest  in the partnership and his wife, who  has a 49%  interest in
the partnership. The Company paid $0.6  million in 2007, $0.6  million in 2008 and $0.6 million in  2009
in rent and related costs (including taxes  and  utilities) to this partnership under a  lease that expires  in
August 2012. The dollar value of the Company’s Chief Executive Officer’s  interest  in the lease
payments in 2009 was $0.3 million. The  dollar value of his wife’s interest in the lease  payment in  2009
was $0.3 million. If the Company’s Chief  Executive  Officer’s interest is combined with that of  his wife
then the total dollar value of his interest  in  the lease payments in 2009  was  $0.6 million.

In 2007, 2008 and  2009, the Company purchased approximately $0.2 million,  $0.1 million and
$13,000 of equipment from an equipment vendor. One of the  Company’s directors is also a director of
the equipment vendor.

ITEM 9A. CONTROLS AND PROCEDURES

We maintain disclosure controls and procedures that are designed  to  ensure that information
required to be disclosed in our reports  under the Securities  Exchange Act of 1934, as amended, is
recorded, processed, summarized and reported  within the  time periods specified in  the Securities and
Exchange Commission’s rules and forms, and that  such information is accumulated and communicated
to our management, including our Chief  Executive  Officer  and Chief Financial  Officer, as appropriate,
to allow timely decisions regarding required disclosure.  In designing and evaluating  the disclosure
controls and procedures, management recognized that any  controls and procedures, no  matter how  well
designed  and operated, can provide only  reasonable assurance of achieving the desired control
objectives, and management necessarily was required  to  apply its judgment in evaluating the
cost-benefit relationship of possible controls and procedures.

As required by SEC Rule 13a-15(b), an evaluation was performed  under the supervision and  with

the participation of our management, including our principal executive officer and  our  principal
financial officer, of the effectiveness  of the design and operation of our disclosure controls  and
procedures (as defined in Rules 13a-15(e) and 15d-15(e)  under the Securities Exchange  Act of 1934) as
of the end of the period covered by this  report.  Based  upon that evaluation, our management,
including our principal executive officer and our principal  financial officer, concluded that the  design
and  operation of these disclosure controls and  procedures  were  effective at  the reasonable assurance
level.

There has been no change in our internal controls over financial  reporting during our most recent

fiscal quarter that has materially affected, or is  reasonably likely to materially affect, our internal
controls over financial reporting.

MANAGEMENT’S REPORT ON INTERNAL CONTROL
OVER FINANCIAL REPORTING

We  are responsible for the preparation and integrity  of our published financial statements. The
financial statements have been prepared in accordance with accounting principles generally accepted  in
the United States of America and, accordingly,  include amounts based  on judgments and estimates
made by our management. We also prepared the other  information included in  the annual report  and
are responsible for its accuracy and consistency with the financial  statements.

We  are responsible for establishing and maintaining  a system of internal control over  financial

reporting, which is intended to provide  reasonable assurance to our  management and Board  of
Directors regarding the reliability of  our financial  statements. The  system includes but is not limited to:

(cid:127) a documented organizational structure and division  of responsibility;

(cid:127) established policies and procedures, including a  code of conduct to foster a  strong ethical

climate which is communicated throughout the  company;

(cid:127) regular reviews of our financial statements by qualified individuals; and

(cid:127) the careful selection, training and  development  of  our  people.

There are inherent limitations in the effectiveness of any system of internal  control,  including the

possibility of human error and the circumvention or  overriding of controls.  Also, the  effectiveness of an
internal control system may change over time.  We have implemented  a  system of internal control that
was designed to provide reasonable assurance regarding the reliability  of  financial reporting  and the
preparation of financial statements in accordance with generally accepted accounting  principles.

We  have assessed our internal control system in relation to criteria for  effective internal  control
over financial reporting described in  ‘‘Internal  Control-Integrated Framework’’ issued by the Committee
of Sponsoring Organizations (COSO) of the Treadway  Commission. Based upon these criteria,  we
believe that, as of  December 31, 2009,  our system of  internal  control over financial reporting was
effective.

The independent registered public accounting  firm,  Ernst & Young  LLP, has audited  our  2009
financial statements. Ernst & Young LLP was  given unrestricted access to  all  financial  records and
related data, including minutes of all  meetings of stockholders, the Board of Directors  and committees
of the Board. Ernst & Young LLP has issued  an unqualified  report on  our  2009 financial statements  as
a result of the audit and also has issued  an unqualified  report on  our internal control over  financial
reporting which is attached hereto.

Report of Independent Registered Public  Accounting Firm
On Internal Control over Financial Reporting

The Board of Directors and Stockholders of Cogent  Communications Group, Inc.

We have audited Cogent Communications Group, Inc.’s internal control over financial reporting as
of December 31, 2009, based on criteria established in  Internal  Control—Integrated Framework issued
by the Committee of Sponsoring Organizations of  the Treadway Commission (the COSO  criteria).
Cogent Communications Group, Inc.’s management is responsible for  maintaining effective internal
control over financial reporting, and for its assessment of the effectiveness of internal control over
financial reporting included in the accompanying  Management’s Report  on Internal Control  over
Financial Reporting. Our responsibility is to express an opinion  on the company’s internal  control  over
financial reporting based on our audit.

We conducted our audit in accordance with the  standards of  the Public Company Accounting
Oversight Board (United States). Those  standards require that we  plan and perform the audit to obtain
reasonable assurance about whether  effective  internal control over financial reporting was maintained
in all material respects. Our audit included obtaining an understanding  of internal control  over
financial reporting, assessing the risk that a material weakness exists, testing and evaluating the design
and  operating effectiveness of internal control based  on the assessed risk, and performing such other
procedures as we considered necessary in the circumstances. We  believe that our audit provides a
reasonable basis for our opinion.

A company’s internal control over financial reporting is a process designed to provide  reasonable

assurance regarding the reliability of  financial reporting and the preparation  of  financial  statements  for
external purposes in accordance with generally accepted accounting  principles. A company’s internal
control over financial reporting includes those policies  and procedures that (1)  pertain to the
maintenance of records that, in reasonable detail, accurately and fairly reflect the  transactions and
dispositions of the assets of the company; (2) provide reasonable assurance that transactions  are
recorded as necessary to permit preparation of financial statements in  accordance with generally
accepted accounting principles, and that receipts and expenditures of the company are being made  only
in accordance with authorizations of management and directors of the company; and  (3) provide
reasonable assurance regarding prevention  or timely detection of unauthorized acquisition, use, or
disposition of the company’s assets that could have a material effect on the financial statements.

Because of its inherent limitations, internal control over  financial  reporting may not prevent or

detect misstatements. Also, projections  of any  evaluation of  effectiveness to future periods are  subject
to the risk that controls may become inadequate  because  of changes in conditions, or  that  the degree
of compliance with the policies or procedures may deteriorate.

In our opinion, Cogent Communications Group,  Inc. maintained,  in all  material respects, effective

internal control over financial reporting as of December 31, 2009, based  on  the COSO criteria.

We also have audited, in accordance with the  standards of  the Public Company Accounting

Oversight Board (United States), the  consolidated balance  sheets of Cogent Communications
Group, Inc. and subsidiaries as of December 31,  2008 and  2009, and the related consolidated
statements of operations, changes in  stockholders’ equity,  and cash flows for each of the  three years in
the period ended December 31, 2009 of Cogent Communications  Group, Inc. and subsidiaries and  our
report dated March 1, 2010 expressed an unqualified  opinion thereon.
