Item 1.

Business

In this report, the words “we,” “our,” “us,” “CoStar” or the “Company” refer to CoStar Group, Inc. and its direct and indirect wholly owned subsidiaries. This

report also refers to our websites, but information contained on those sites is not part of this report.

CoStar Group, Inc., a Delaware corporation, founded in 1987, is the number one provider of information, analytics and online marketplaces to the commercial
real estate industry in the United States (“U.S.”) and United Kingdom (“U.K.”) based on the fact that we offer the most comprehensive commercial real estate
database available; have the largest research department in the industry; own and operate leading online marketplaces for commercial real estate and apartment
listings in the U.S. based on the numbers of unique visitors and site visits per month; and provide more information, analytics and marketing services than any of
our competitors. We have created and compiled a standardized platform of information, analytics and online marketplace services where industry professionals and
consumers  of  commercial  real  estate,  including  apartments,  and  the  related  business  communities,  can  continuously  interact  and  facilitate  transactions  by
efficiently accessing and exchanging accurate and standardized real estate-related information. Our service offerings span all commercial property types, including
office, retail, industrial, multifamily,  commercial  land, mixed-use and hospitality. We manage our business geographically in two operating segments, with our
primary  areas  of  measurement  and  decision-making  being  North  America,  which  includes  the  U.S.  and  Canada,  and  International,  which  primarily  includes
Europe, Asia-Pacific and Latin America. On October 22, 2019, we acquired STR, Inc. and STR Global, Ltd. (together with STR, Inc., "STR"), which provides
benchmarking and analytics for the hospitality industry. See Note 4 to the accompanying Notes to the Consolidated Financial Statements included in Part IV of this
Annual Report on Form 10-K for further discussion of this acquisition.

Strategy

Our strategy is to provide industry professionals and consumers of commercial real estate and apartments with critical knowledge to explore and complete
transactions by offering the most comprehensive, timely and standardized information on commercial real estate and apartments and the right tools to be able to
effectively utilize that information. Over time, we have expanded, and we continue to expand, our services for commercial real estate information, analytics and
online marketplaces in an effort to continue to meet the needs of the industry as it grows and evolves.

Our standardized platform includes the most comprehensive proprietary database in the industry; the largest research department in the industry; proprietary
data  collection,  information  management  and  quality  control  systems;  a  large  in-house  product  development  team;  a  broad  suite  of  web-based  information,
analytics  and  online  marketplace  services;  a  large  team  of  analysts  and  economists;  and  a  large,  diverse  base  of  clients.  Our  database  has  been  developed  and
enhanced for more than 30 years by a research department that makes thousands of daily database updates. In addition to our internal efforts to grow the database,
we  have  obtained  and  assimilated  a  significant  number  of  proprietary  databases.  Our  comprehensive  commercial  real  estate  database  powers  our  information
services, sources data used in our analytic services and provides content for most of our online marketplace services. Our ability to utilize the same commercial
real estate information across our standardized platform creates efficiencies in operations and improves data quality for our customers.

We deliver  our comprehensive commercial  real estate information  content to our U.S. and certain customers in Europe primarily via an integrated  suite of
online  service  offerings  that  includes  information  about  space  available  for-lease,  comparable  sales  information,  information  about  properties  for-sale,  tenant
information,  Internet  marketing  services,  analytical  capabilities,  information  for  clients’  websites,  information  about  industry  professionals  and  their  business
relationships, data integration and industry news. We also operate complementary online marketplaces for commercial real estate listings and apartment rentals.
We strive to cross-sell our services to our customers in order to best suit their needs.

Information about our revenues, long-lived assets and total assets derived from and located in foreign countries is included in Notes 2, 3 and 14 of the Notes to
Consolidated Financial Statements included in this Annual Report on Form 10-K. Revenues; net income (loss) before interest and other income (expense), income
taxes,  depreciation  and  amortization  (“EBITDA”);  and  total  assets  and  liabilities  for  each  of  our  segments  are  set  forth  in  Notes  3 and  14 to  our  consolidated
financial  statements.  Information  about  risks  associated  with  our  foreign  operations  is  included  in  “Item  1A.  Risk  Factors”  and  “Item  7A.  Quantitative  and
Qualitative Disclosures about Market Risk” in this Annual Report on Form 10-K.

We  have  five  flagship  brands  -  CoStar®, LoopNet®, Apartments.comTM, BizBuySell® and  LandsofAmerica TM,  which  are  accessible  via  the  Internet  and
through  our  mobile  applications.  Our  subscription-based  services  consist  primarily  of  CoStar  Suite® services,  which  include  information,  analytics  and  online
marketplace services offered to the commercial real estate industry and related professionals. CoStar Suite® is sold as a platform of service offerings consisting of
CoStar Property Professional®, CoStar

4

COMPS Professional® and CoStar Tenant®, and is our largest service offering in our North America and International operating segments.

Our LoopNet subscription-based, online marketplace enables commercial property owners, landlords, and brokers to list properties for-sale or for-lease and to
submit detailed information about property listings. Commercial real estate agents, buyers and tenants use LoopNet extensively to search for available property
listings that meet their criteria.

 network  of

Apartments.comTM is  part

 which  also  includes  ApartmentFinder.com TM,

 ForRent.com®,
 marketing  sites,
ApartmentHomeLiving.comTM, WestsideRentals.com®, AFTER55.com®, CorporateHousing.comTM, ForRentUniversity.com®, Apartamentos.comTM, which is our
apartment-listing  site  offered  exclusively  in  Spanish,  and  OffCampusPartners.com,  which  we  acquired  on  June  12,  2019,  and  which  provides  student  housing
marketplace content and powers off campus housing sites for many universities across the U.S. Our apartment marketing network of subscription-based services
offers  renters  a  searchable  database  of  apartment  listings  and  provides  property  owners,  professional  property  management  companies  and  landlords  with  an
advertising  destination.  Our  apartment  marketing  network  draws  on  and  leverages  CoStar’s  multifamily  database,  which  contains  detailed  information  on
apartment properties and is designed to meet renter preferences and demands, in order to drive traffic to those sites and attract advertisers who prefer to advertise
on  heavily  trafficked  apartment  websites.  Our  network  of  apartment  marketing  sites  provides  a  comprehensive  selection  of  rentals,  information  on  actual
availabilities and rents, and in-depth data on neighborhoods, including restaurants, nightlife, history, schools and other facts important to renters. To help renters
find  the  information  that  meets  their  needs,  we  have  sites  that  also  offer  innovative  search  tools  such  as  the  PolygonTM Search  tool,  which  allow  renters  to
specifically  define  the  area  in  which  they  want  to  find  an  apartment  and  Plan  Commute  tools,  which  allow  renters  to  search  property  listings  that  meet  their
transportation needs. We also offer complementary services to the apartment industry, including the ability for renters to apply for rentals online, and for landlords
to receive applications, screen tenants, and process rental payments and lease renewals. 

Our  BizBuySell  services,  which  include  BizQuest®  and  FindaFranchise,  provide  an  online  marketplace  for  businesses  and  franchises  for-sale.  Our
LandsofAmerica services, which include LandAndFarm and LandWatch®, provide an online marketplace for rural lands for-sale and are also accessible via our
Land.com domain.

We provide other services that complement those offered through our five flagship brands. These include real estate and lease management solutions, lease
administration  and abstraction  services, through our CoStar Real Estate Manager service offerings; market research, consulting and analysis, portfolio and debt
analysis, and management and reporting capabilities, through our CoStar Investment Analysis and CoStar Risk Analytics service offerings; and benchmarking and
analytics for the hospitality industry through our STR service offerings.

Our services are typically distributed to our clients under subscription-based license agreements that renew automatically, a majority of which have a term of
at least one year. Upon renewal, many of the subscription contract rates may change in accordance with contract provisions or as a result of contract renegotiations.
To encourage clients to use our services regularly, we generally charge a fixed monthly amount for our subscription-based services rather than charging fees based
on actual system usage or number of paid clicks. Depending on the type of service, contract rates are generally based on the number of sites, number of users,
organization size, the client's business focus, geography, the number and types of services to which a client subscribes, the number of properties a client advertises
and the prominence and placement of a client's advertised properties in the search results. Our subscription clients generally pay contract fees on a monthly basis,
but  in  some  cases  may  pay  us on  a  quarterly  or  annual  basis.  We  generally  see  higher  sales  of  Apartments.com  listing  services  during the  peak  summer  rental
season  and  higher  CoStar  suite  sales  towards  the  end  of  the  year,  however  sales  fluctuate  from  year-to-year  and  revenue  is  not  generally  seasonal  because  our
services are typically sold on a subscription basis.

Expansion and Growth

Acquisitions

We  have  expanded  and  continue  to  expand  the  coverage  and  depth  of  our  information,  analytics  and  online  marketplace  services.  In  addition  to  organic
growth, we have grown our business through strategic acquisitions. Most recently, on June 12, 2019, we acquired Off Campus Partners, LLC (“OCP”), a provider
of student housing marketplace content and technology to U.S. universities, and on October 22, 2019, we acquired STR, a global provider of benchmarking and
analytics  for  the  hospitality  industry.  We  continue  to  integrate  our  recent  acquisitions  and  the  services  they  offer  into  our  CoStar  network.  See  Note  4  to  the
accompanying Notes to the Consolidated Financial Statements included in Part IV of this Annual Report on Form 10-K for further discussion of these acquisitions.

5

On February 11, 2020, we agreed to acquire, for $588 million in cash, all the equity interests of RentPath, as reorganized following an internal restructuring
pursuant  to  and  under  the  joint  chapter  11  plan  of  reorganization  of  RentPath  and  certain  of  its  subsidiaries.  Closing  of  the  acquisition  is  subject  to  customary
closing conditions, including the expiration or termination of any applicable waiting period under applicable antitrust laws and approval by the bankruptcy court.
RentPath  is  a  provider  of  digital  marketing  solutions  for  rental  properties  through  a  network  of  Internet  listing  websites,  including  Rent.com,
ApartmentsGuide.com, Rentals.com and LiveLovely.com. See Note 19 to the accompanying Notes to the Consolidated Financial Statements included in Part IV of
this Annual Report on Form 10-K for further discussion of this acquisition.

Development, Investments and Expansion

We are committed to supporting, improving and enhancing our information, analytics and online marketplace solutions, including expanding and improving
our offerings for property owners, property managers and renters. We expect to continue our software development efforts to improve existing services, introduce
new services, integrate and cross-sell services, and expand and develop supporting technologies for our research, sales and marketing organizations.

We evaluate potential changes to our service offerings from time to time in order to better align the services we offer with customers’ needs. Further, in some
cases, when integrating and coordinating our services and assessing industry and client needs, we may decide to combine, shift focus from, de-emphasize, phase
out, or eliminate a service that, among other things, overlaps or is redundant with other services we offer. In the event that we eliminate or phase out particular
service  offerings,  we  may  experience  reduced  revenues  and  earnings.  The  decision  to  eliminate  or  phase  out  a  service  offering  may  also  ultimately  result  in
increased revenues and earnings from sales of other services we offer in lieu of the eliminated or phased out services. However, we cannot predict with certainty
the amount or timing of any reductions in revenues and earnings or subsequent increases in revenues and earnings, if any, resulting from the elimination or phasing
out of any service offering.

On November 18, 2018, we acquired Cozy Services, Ltd. (“Cozy”), a leading provider of online rental solutions offering a broad spectrum of services to both
landlords  and  tenants.  We  continue  to  integrate  Cozy's  online  rental  and  payments  technology  into  the  Apartments.com  platform,  creating  an  integrated  online
rental solution. The new platform allows renters to apply for-leases online, for landlords to run tenant credit and background checks and make and process online
payments. In 2019, we completed the integration of Realla Ltd. (“Realla”), the operator of a commercial property listings and data management platform that we
acquired  in  October  2018,  with  our  CoStar  UK  operations.  A  single  point  of  data  entry  now  allows  our  clients  to  display  their  commercial  real  estate  listings
through the CoStar Suite service offering and to make them visible to prospective tenants and investors through Realla’s marketing portal. Over time, we plan to
integrate STR data and services with CoStar Suite to create new products and services for our customers. We plan to drive international expansion, in part, through
STR's global operations and to apply STR's benchmarking expertise to other commercial real estate segments served by CoStar.

We believe that our integration efforts and continued investments in our services, including acquisitions and expansion of our existing service offerings, have
created a platform for long-term revenue growth. We expect these investments to result in further penetration of our subscription-based services and the successful
cross-selling of our services to customers in existing markets.

We have invested in the expansion and development of our field sales force to support the growth and expansion of our company and our service offerings,
and plan to continue to invest in, evaluate and strategically position our sales force as the Company continues to develop and grow. Specifically, we continue to
invest in marketing our services, as well as in our research operations to support continued growth of our information and analytics offerings to meet the growing
content needs of our clients. We plan to significantly increase our investment in Apartments.com marketing in 2020, including search engine marketing and TV
and  digital  video  advertising.  While  we  believe  the  investments  we  make  in  our  business  create  a  platform  for  growth,  those  investments  may  reduce  our
profitability and adversely affect our near-term financial position.

Industry Overview

The market for commercial real estate information and analysis is vast based on the variety, volume and value of transactions related to commercial real estate.
Each transaction has multiple participants and multiple information requirements, and in order to facilitate transactions, industry participants must have extensive,
accurate and current information and analysis. Members of the commercial real estate and related business community require daily access to current data such as
space availability, properties for-sale, rental units available, rental rates, vacancy rates, tenant movements, sales comparables, supply, new construction, absorption
rates and other important market developments to carry out their businesses effectively. Market research (including historical and forecast conditions) and applied
analytics are instrumental to the success of commercial real estate industry participants. There is a strong need for an efficient marketplace, where commercial real
estate  professionals  can  exchange  information,  evaluate  opportunities  using  standardized  data  and  interpretive  analyses,  and  interact  with  each  other  on  a
continuous basis.

A  large  number  of  parties  involved  in  the  commercial  real  estate  and  related  business  community  make  use  of  the  services  we  provide  in  order  to  obtain

information they need to conduct their businesses, including:

• Sales and leasing brokers

• Government agencies

• Property owners

• Property managers

• Mortgage-backed security issuers

• Appraisers

• Design and construction professionals

• Pension fund managers

• Real estate developers

• Reporters

• Real estate investment trust managers

• Tenant vendors

•

Investment and commercial bankers

• Building services vendors

• Mortgage bankers

• Mortgage brokers

• Retailers

• Hospitality owners

• Communications providers

•

•

•

Insurance companies’ managers

Institutional advisors

Investors and asset managers

The  commercial  real  estate  and  related  business  community  historically  operated  in  an  inefficient  marketplace  because  of  the  fragmented  approach  to
gathering  and  exchanging  information  within  the  marketplace.  Various  organizations,  including  hundreds  of  brokerage  firms,  directory  publishers  and  local
research companies, collected data on specific markets and developed software to analyze the information they independently gathered. This highly fragmented
methodology  resulted  in  duplication  of  efforts  in  the  collection  and  analysis  of  information,  excessive  internal  cost  and  the  creation  of  non-standardized  data
containing varying degrees of accuracy and comprehensiveness, resulting in a formidable information gap.

The  creation  and  maintenance  of  a  standardized  information  platform  for  commercial  real  estate  requires  infrastructure  including  a  standardized  database,
accurate and comprehensive research capabilities, experienced analysts, easy to use technology and intensive participant interaction. By combining our extensive
database, researchers, our experienced team of analysts and economists, technological expertise and broad customer base, we believe that we have created such a
platform.

The apartment rental advertising industry serves property managers and owners who are tasked with finding renters to occupy vacant apartments, as well as
renters  who  are  searching  for  their  next  home.    Property  managers  have  several  options  at  their  disposal,  including  their  own  websites,  drive-by  and  outdoor
advertising,  traditional  classified  ads,  free  online  listing  services,  search  engine  marketing  and  Internet  listings  services  (“ILS”),  like  Apartments.com  and  the
network of apartment listing websites we own and operate. Many apartment ILS websites feature only the rental availabilities that larger property owners pay to
advertise, resulting in a poor user experience in which the renter’s search criteria return either limited or no results, irrelevant results or stale results that do not
represent actual availabilities.

We believe that consumers expect accurate, actionable and comprehensive apartment rental information. Our apartment ILS websites include renter-focused
features  like  the  ability  to  filter  search  results  according  to  various  criteria  (e.g.,  commute  time  to  work);  professional  images  of  the  properties,  including
immersive  videos  and  3-D  interactive  models;  custom  neighborhood  profiles;  and  tenant  reviews.  Our  network  of  apartment  listing  websites  draws  on  our
multifamily  database  and  includes  researched  and  verified  information.  We  proactively  gather  information  on  available  rentals  to  improve  the  accuracy  of  the
listings on our apartment ILS websites, including real time unit-level availability, current pricing, and rent specials.  We have continually invested in our network
to improve the features and services offered to property managers and website users. Recent additions include: dynamic lead forms that provide more information
about prospective residents, a reporting suite that provides customers with rent comparables, making rent trends information publicly available and free digital ad
retargeting,  and  integrated  online  rental  solutions,  including  lease  applications,  and  tenant  credit  and  background  checks.  We  believe  that  we  have  created  and
maintain easily searchable apartment ILS websites with a comprehensive selection of rentals, information on actual rental availabilities and rents, and in-depth data
on neighborhoods, as well as easy to use and actionable tools for the rental process.

CoStar’s Comprehensive Database

CoStar has spent more than 30 years building and acquiring databases of commercial real estate information, which includes information on leasing, sales,
comparable sales, tenants, and demand statistics, as well as digital images. This highly complex database is comprised of hundreds of data fields, tracking such
categories as location, site and zoning information, building characteristics, space and unit availability, tax assessments, ownership, sales and lease comparables,
space requirements, number of retail stores, number of listings, mortgage and deed information, for-sale and for-lease listings, income and expense histories,

7

tenant  names,  lease  expirations,  contact  information,  historical  trends,  demographic  information  and  retail  sales  per  square  foot.  The  database  also  includes
building photographs, aerial photographs, 3D virtual tours, plat maps and floor plans.

CoStar Research

Research Department. Our research professionals undergo an extensive training program so that we can maintain consistent research methods and processes
throughout our research department. Our researchers collect and analyze commercial real estate information through phone calls, e-mails and Internet updates, in
addition to field inspections, public records review, news monitoring and third-party data feeds. We have also set up direct feeds from larger apartment sites and
have  put  in  place  an  automated  system  that  compiles  information  sourced  from  the  Internet  in  order  to  provide  the  most  up-to-date  information  on  rental
availabilities.

Our researchers are responsible for maintaining the accuracy and reliability of our database information. As part of their update process, researchers develop
cooperative relationships with industry professionals that allow them to gather useful information. Because of the importance commercial real estate professionals
place on our data and our prominent position in the industry, many of these professionals routinely take the initiative and proactively report available space and
transactions through our on-line tool, Marketing Center, or directly to our researchers.

CoStar's  field  research  effort  includes  physical  inspection  of  properties  in  order  to  research  new  availabilities,  find  additional  property  inventory,  new
construction,  collect  tenant  information,  verify  existing  information,  photograph  properties  and  create  high  quality  videos  of  interior  spaces  (including  walk-
through  videos  and  3D  virtual  tours),  amenities  and  exterior  features  of  properties.  CoStar  utilizes  high-tech,  field  research  vehicles  primarily  within  North
America and Europe. A significant majority of these vehicles are customized, energy efficient hybrid cars that are equipped with computers, Global Positioning
System tracking software, high resolution digital cameras and handheld laser instruments to precisely measure buildings and geo-code and position them on digital
maps. Each CoStar vehicle uses wireless technology to track and transmit field data. A typical site inspection consists of photographing the building, measuring the
building, geo-coding the building, capturing “for-sale” or “for-lease” sign information, counting parking spaces, assessing property condition and construction, and
gathering tenant information. Field researchers also canvass properties, collecting tenant data suite-by-suite. CoStar also utilizes a low-flying airplane and a fleet of
drones to conduct aerial research of commercial real estate. We place researchers on the low-flying aircraft to scout additional commercial developments and take
aerial  photographs  and  videos.  Our  U.S.  drone  operators  are  Federal  Aviation  Administration  certified  and  trained  to  capture  aerial  photographs  and  videos  of
commercial  real  estate.  Our  drone  operators  in  the  U.K.  and  Canada  are  certified  and  trained  to  Civil  Aviation  Authority  standards  with  a  permission  for
commercial operations pending.

Data and Image Providers. We license a small portion of our data and images from public record providers and third-party data sources. Licensing agreements
with these entities allow us to use a variety of commercial real estate information, including property ownership, tenant information, demographic information,
maps,  aerial  photographs  and  3D  virtual  apartment  tours  of  apartment  communities,  all  of  which  enhance  various  CoStar  services.  These  license  agreements
generally grant us a non-exclusive license to use the data and images in the creation and supplementation of our information, analytics and online marketplaces.

Management and Quality Control Systems. Our research processes include automated and non-automated controls to ensure the integrity of the data collection
process.  A  large  number  of  automated  data  quality  tests  check  for  potential  errors,  including  occupancy  date  conflicts,  available  square  footage  greater  than
building area, typical floor space greater than land area and expired leases. We also monitor changes to critical fields of information to ensure all information is
kept in compliance with our standard definitions and methodology. Our non-automated quality control procedures include:

•
•
•
•

Calling our information sources on recently updated properties to re-verify information;
Performing periodic research audits and field checks to determine if we correctly canvassed buildings;
Providing training and retraining to our research professionals to ensure accurate and standardized data compilation; and
Compiling measurable performance metrics for research teams and managers for feedback on data quality.

Finally, one of the most important and effective quality control measures we rely on is feedback provided by the commercial real estate professionals using

our data every day.

technologies  and  systems  that  introduce  efficient  workflows  and  controls  designed  to  increase  the  production  capacity  of  our  research  teams  and  improve  the
quality of our data. Over the years, the team has developed data collection and quality control mechanisms that we believe are unique within the commercial real
estate industry. The team continues to develop and modify our enterprise information management system that integrates CoStar's sales, research, field research,
customer  support  and  accounting  information.  We  use  this  system  to  maintain  our  commercial  real  estate  research  information,  manage  contacts  with  the
commercial  real  estate  community,  provide  research  workflow  automation  and  conduct  daily  automated  quality  assurance  checks.  In  addition,  our  information
technology team has also developed fraud-detection technology to detect and prevent unauthorized access to our services. To supplement the measures we take to
prevent misuse of our information, we recently added state of the art adaptive authentication technology to the login process of our CoStar Suite product.

Our information technology professionals maintain the servers and network components necessary to support CoStar services and research systems. CoStar's
core services are served from multiple data centers to support uninterrupted service for our customers. CoStar’s services are continually monitored in an effort to
ensure our customers fast and reliable access.

fields, end to end encryption, endpoint detection and response systems and services, security information and event management systems, off-site storage, cloud
services, end user and developer security training, multilayered anti-phishing malware and spam protections and other protective measures in an effort to ensure the
availability and security of all core systems.

Services

Our suite of information, analytics and online marketplaces is branded and marketed to our customers. Our services are primarily derived from a database of
building-specific  information  and  offer  customers  specialized  tools  for  accessing,  analyzing  and  using  our  information.  Over  time,  we  have  enhanced  and
expanded, and expect to continue to enhance and expand our existing information, analytics and online marketplace services and we have developed and expect to
continue  to  develop  additional  services  that  make  use  of  our  comprehensive  database  to  meet  the  needs  of  our  existing  customers  as  well  as  potential  new
categories of customers.

Our principal information, analytics and online marketplace services, are described in the following paragraphs:

comprehensive property information, enabling the subscriber to compare lease alternatives, either from a landlord or tenant perspective.

Clients

We  draw  clients  from  across  the  commercial  real  estate  and  related  business  community,  including  commercial  real  estate  brokers,  owners,  developers,
landlords, property managers, financial institutions, retailers, vendors, appraisers, investment banks, government agencies and other parties involved in commercial
real estate. For the years ended December 31, 2019, 2018 and 2017, no single client accounted for more than 5% of our revenues.

Sales and Marketing

Our  overall  sales  strategy  is  to  attract  new  clients,  renew  existing  customers  and  cross-sell  the  numerous  solutions  we  have  to  offer.  Our  sales  teams  sell
multiple products and are primarily located in field sales offices throughout the U.S., with others in Canada, the U.K., Spain, France, and Germany. Our inside
sales teams are largely based in Washington, DC and Richmond, Virginia. Our inside sales professionals actively work lead lists, prospect for new customers and
perform product demonstrations over the telephone. They utilize the Internet and remote presentation tools to convey the multiple solutions we have to offer.

Our local offices typically serve as the location for field sales, client support and field research operations. This enables our clients to benefit from a local
presence. The sales force is responsible for selling to new prospects, training new and existing clients, providing ongoing customer support, renewing contracts and
identifying cross-selling opportunities. In addition, the sales force has the primary front-line responsibility for customer service, ensuring client satisfaction and
building  long-term  relationships.  Our  local  offices  act  as  hubs  for  training,  sources  of  market  insight,  product  feedback  sessions  and  connecting  industry
participants.

We  use  incentives,  including  discounts  to  encourage  existing  clients  to  buy  additional  products  and  services.  This  deepens  our  customer  relationships  and
offers  more  value.  We  actively  manage  all  client  accounts  with  frequent  meetings,  trainings  and  updates  on  new  enhancements.  In  2019,  we  successfully
implemented a number of important sales initiatives, including initiatives that focused on property owners in the U.S. Our focus on the owner segment allowed us
to  successfully  position  LoopNet  Signature  Ads  as  a  valuable  solution  for  a  property  owner’s  major  risk,  namely,  the  cost  of  vacant  space  and  the  resulting
negative impact on valuation of the property or portfolio. Our CoStar U.K. sales force concentrated on reaching customer locations and visiting or training users on
the numerous product enhancements we released in 2019. In Canada, our reps were focused on targeting brokers, owners and lender prospects.

We seek to make our services  essential  to our clients’  businesses. To encourage  clients  to use our services  regularly,  we generally  charge a fixed monthly
amount for our subscription-based information services rather than fees based on actual system usage. Contract rates for subscription-based services are generally
based on the number of sites, number of users, organization size, the client’s business focus, geography and the range of services subscribed for. Our marketing
solutions are priced by exposure levels, the number of properties/spaces for-lease, rent or sale and the market in which they are offered. Listings for customers who
purchase packages with the highest level of exposure usually appear first in search results and offer the richest media content and engagement opportunities for
tenants searching for space, renters looking for an apartment or investors seeking an opportunity. Our subscription clients generally pay contract fees on a monthly
basis, but in some cases may pay us on a quarterly or annual basis.

Our  primary  marketing  methods  include:  service  demonstrations;  face-to-face  networking;  web-based  or  digital  marketing;  direct  marketing  such  as  direct
mail and email; communication via our corporate website and news services; participation in trade shows and industry events; Company-sponsored events; print
advertising  in  trade  magazines  and  other  business  publications;  client  referrals;  content  marketing  including  webinars,  seminars,  and  white  papers  and  other
company newsletters distributed via email to our clients and prospects. Our CoStar and LoopNet databases have been integrated to enhance CoStar information
services as information tools and LoopNet marketplace services as marketing tools. This integration provides clients the ability to enter listings into our Marketing
Center tool and to update their listings in CoStar and LoopNet simultaneously. To familiarize  clients with the integration and benefits of the tool, we provided
video tutorials and hosted numerous webinars, in addition to web-based marketing and direct marketing efforts. In 2019, over one hundred thousand commercial
real estate professionals and other users successfully made millions of updates to their listings using our Marketing Center.

To  generate  brand  awareness  and  site  traffic  for  the  Apartments.com  network  of  rental  websites,  we  utilize  a  multi-channel  marketing  campaign  featuring
television and radio ads, online and digital advertising impressions, streaming audio and podcasts, social media, email, public relations and news articles, out-of-
home  and  paid  search  marketing,  all  of  which  are  reinforced  with  substantial  Search  Engine  Optimization  efforts.  In  2019,  we  increased  our  investment  in
Apartments.com marketing, and we plan to further increase that investment in 2020. We plan to continue to utilize these marketing methods and will continue to
work to determine the optimal level of marketing investment for our services for future periods.

12

 
 
Comprehensive  digital  marketing  and  direct  marketing  are  effective  means  for  us  to  find  prospective  clients.  Our  digital  marketing  efforts  include  Search
Engine Optimization, paid advertising with major search engines, social media and display advertising on commercial real estate news and business websites and
mobile applications, and our direct marketing efforts include television, radio, out-of-home ads, direct mail and email and, when applicable, make extensive use of
our unique, proprietary database. Once we have identified a prospective client, our most effective sales method is a service demonstration. We use various forms of
integrated marketing and advertising to build brand awareness, brand identity and reinforce the value and benefits of our services. We also sponsor and attend local
association activities and events, including industry-leading events for commercial real estate brokers, property owners, investors and retail and financial services
institutions, and attend or exhibit at industry trade shows and conferences to reinforce our relationships with our core user groups.

News  has  always  been  a  valuable  part  of  CoStar's  core  subscription  offering.  CoStar's  news  teams  report  on  the  latest  deals  and  developments  across  our
markets, keeping subscribers informed and driving higher usage in our core product. In 2019, we enhanced our news offerings. We expanded our coverage of real
estate  investment  trusts,  and  working  with  the  analyst  team,  added  quarterly  video  updates  on  national  and  local  markets.  We  bolstered  our  coverage  of  the
hospitality industry by adding relevant news from Hotel News Now, a unit of newly acquired STR. We launched a new weekly column on economic policy that
proved so popular we made it available as a separate email newsletter to subscribers. We continued to build on our newsletter franchise, giving subscribers the
ability  to  select  the  coverage  they  wished  to  receive  in  daily  emails.  In  addition,  we  now  showcase  news  excerpts  and  advertising  on  the  publicly  available
CoStar.com.

We believe the ability to customize and personalize news for the user's specific interests makes our news service even more relevant and valuable to

subscribers. In addition to encouraging more engagement through logins and time on site, we believe a more robust news operation also provides more options and
formats for advertising to the commercial real estate audience.

We  currently  offer  dozens  of  webinars  each  year  aimed  at  helping  customers  learn  more  about  the  commercial  real  estate  industry  and  how  to  use  our
services.  The  webinars  are  available  both  as  live  presentations  and  as  on-demand  programs  hosted  on  our  website.  On  a  monthly  basis,  we  issue  the  CoStar
Commercial  Repeat  Sales  Index  ("CCRSI"),  a  comprehensive  set  of  benchmarks  that  investors  and  other  market  participants  can  use  to  better  understand
commercial real estate price movements. CCRSI is produced using our underlying data and is publicly distributed by CoStar through the news media and made
available online.

Competition

The market for information, analytics and online marketplaces generally is competitive and extremely dynamic. In the commercial real estate and apartment

rentals industries, we believe the principal competitive factors affecting these services and providers are:

•
•
•
•
•
•
•
•
•
•
•
•
•
•
•

Quality and depth of the underlying databases;
Quality and quantity of leads and leases delivered;
Ease of use, flexibility and functionality of the software;
Intuitiveness and appeal of the user interface;
Timeliness of the data, including listings;
Breadth of geographic coverage and services offered;
Completeness and accuracy of content;
Client service and support;
Perception that the service offered is the industry standard;

Capital resources.

13

We compete directly and indirectly for customers with the following categories of companies:

•

•

•

•

•

•

•

•

Online marketing services, websites or data exchanges targeted to commercial real estate brokers, buyers and sellers of commercial real estate properties,
insurance  companies,  mortgage  brokers  and  lenders,  such  as  Reed  Business  Information  Limited  and  its  Estates  Gazette  and  Radius  Data  Exchange
products,  RealMassive,  officespace.com,  42floors,  Brevitas,  Catylist,  Ten-X,  RealNex  MarketPlace,  TenantWise,  www.propertyshark.com,  Rofo,
BuildingSearch.com, CIMLS, CompStak, Rightmove, CommercialCafe, CREXi, Truss, TotalCommercial.com and DebtX;

Publishers and distributors of information, analytics and marketing services, including regional providers and national print publications, such as CBRE
Economic Advisors, Marshall & Swift, Yale Robbins, REIS Network (part of the Moody's Analytics Accelerator), Real Capital Analytics, Real Capital
Markets, Reonomy, The Smith Guide, Yardi Matrix, RealPage and its Axiometrics business and ReScour, Inc.;

Search engine and Internet listing services featuring apartments for rent, such as Google, Bing, Facebook Marketplace, ApartmentGuide.com, Rent.com,
Rentals.com,  Zillow  Rentals,  Trulia  Rentals,  StreetEasy,  NakedApartments.com,  HotPads.com,  MyNewPlace.com,  Zumper,  PadMapper,  craigslist,
ApartmentList.com, Move.com, Realtor.com, Homes.com, Adobo, RadPad, RentJungle, RentCafe.com, RentHop, RentBerry, and ApartmentRatings;

Locally controlled real estate boards, exchanges or associations sponsoring property listing services and the companies with whom they partner, such as
Catylist, the National Association of Realtors, CCIM Institute, Society of Industrial and Office Realtors, the Commercial Association of Realtors Data
Services and AIR CRE;

Real estate portfolio management software solutions, such as Cougar Software, MRI Software, Altus, Intuit and SiteCompli;

Real estate lease management and administration software solutions, such as Accruent, Tririga, Manhattan Software, Tango Analytics, Lease Accelerator
and AMT Direct;

In-house research departments operated by commercial real estate brokers; and

Public record providers.

As the market for information, analytics and online marketplaces develops, additional competitors (including companies which could have greater access to
data, financial, product development, technical, analytic or marketing resources than we do) may enter the market and competition may intensify. For example, a
company like Bloomberg L.P. has the resources, and has previously announced an intention, to move into the commercial real estate information business. Further,
a  company  like  Google,  which  has  a  far-reaching  web  presence  and  substantial  data  aggregation  capabilities,  could  enter  the  commercial  real  estate  marketing
arena. A company like Zillow, which already has a presence in residential real estate and the apartment rentals industry, could use its resources to further expand in
the  online  apartment  rentals  industry  creating  greater  competition  among  Internet  listing  services  for  the  marketing  budgets  of  property  managers  and  property
owners. While we believe that we have successfully differentiated ourselves from existing competitors, current or future competitors could materially harm our
business.

Proprietary Rights

To protect our proprietary rights in our methodologies, database, software, trademarks and other intellectual property, we depend upon a combination of:

•
•
•
•
•
•

Trade secret, misappropriation, unfair competition, copyright, trademark, computer fraud, database protection and other laws;
Registration of copyrights and trademarks;
Nondisclosure, noncompetition and other contractual provisions with employees and consultants;
License agreements with customers;
Patent protection; and
Technical measures.

14

  
We seek to protect our software’s source code, our database and our photography as trade secrets and under copyright law. Although copyright registration is
not a prerequisite for copyright protection, we have filed for copyright registration for many of our databases, photographs, software and other materials. Under
current U.S. copyright law, the arrangement and selection of data may be protected, but the actual data itself may not be. Certain U.K. database protection laws
provide  additional  protections  for  our  U.K.  databases.  We  license  our  services  under  license  agreements  that  grant  our  clients  non-exclusive,  non-transferable
rights.  These  agreements  restrict  the  disclosure  and  use  of  our  information  and  prohibit  the  unauthorized  reproduction  or  transfer  of  any  of  our  proprietary
information, methodologies or analytics.

We also attempt to protect our proprietary databases, our trade secrets and our proprietary information through confidentiality and noncompetition agreements
with  our  employees  and  consultants.  Our  services  also  include  technical  measures  designed  to  detect,  discourage  and  prevent  unauthorized  access  to  and/or
copying  of  our  intellectual  property.  We  have  established  an  internal  antipiracy  team  that  uses  fraud-detection  technology  to  continually  monitor  use  of  our
services to detect and prevent unauthorized access, and we actively prosecute individuals and firms that engage in this unlawful activity.

We maintain U.S. and international trademark registrations for CoStar’s core service names and proactively file U.S. and international trademark applications
covering our new and planned service names. Our federally registered trademarks include CoStar®, CoStar Suite®, CoStar Property®, CoStar COMPS®, CoStar
Tenant®, CoStar Lease Analysis®, LoopNet®, Showcase.com®, Cityfeet.com®, Apartments.com®, and Lands of America®, among many others.  In the U.S.,
trademarks  are  generally  valid  as  long  as  they  are  in  use  and  have  not  been  found  to  be  generic.  We  consider  our  trademarks  in  the  aggregate  to  constitute  a
valuable asset. In addition, we maintain a patent portfolio that protects certain of our systems and methodologies. We currently have one granted patent in the U.K.,
which expires in 2021, covering, among other things, certain of our field research methodologies, four patents in Canada, which expire in 2021 (2 patents) and
2036 (2 patents), covering, among other things, certain features of our field research methodologies and user interface features, and thirteen patents in the U.S.
which expire in 2020, 2021 (2 patents), 2022 (2 patents), 2025, 2032 (2 patents), 2036, and 2037 (4 patents), covering, among other things, certain features of our
field  research  methodologies  and  user  interface  feature.  We  regard  the  rights  protected  by  our  patents  as  valuable  to  our  business,  but  do  not  believe  that  our
business is materially dependent on any single patent or portfolio of patents as a whole.

Employees

As of January 31, 2020, we employed 4,337 employees. None of our employees are represented by a labor union. We have experienced no work stoppages.
We believe that our employee relations are excellent. In common with many German companies, employees in our German subsidiary, Thomas Daily GmbH, have
elected five fellow employees to form a Works Council, which represents our employees at the location. The Works Council has certain co-determination rights
and rights to receive information from us and engage us in discussions under applicable law.

Risk Factors

Our revenues and financial position will be adversely affected if we are not able to attract and retain clients. Our success and revenues depend on attracting
and retaining subscribers to our information, analytics and online marketplaces. Our subscription-based information, analytics and online marketplaces generate the
largest  portion  of  our  revenues.  However,  we  may  be  unable  to  attract  new  clients,  and  our  existing  clients  may  decide  not  to  add,  not  to  renew  or  to  cancel
subscription  services.  In  addition,  in  order  to  increase  our  revenue,  we  must  continue  to  attract  new  customers,  continue  to  keep  our  cancellation  rate  low  and
continue to sell new services to our existing customers. We may not be able to continue to grow our customer base, keep the cancellation rate for customers and
services low or sell new services to existing customers as a result of several factors, including without limitation: economic pressures; the business failure of a
current client or clients; a decision that customers have no need for our services; a decision to use alternative services; customers’ and potential customers’ pricing
and  budgetary  constraints;  consolidation  in  the  real  estate  and/or  financial  services  industries;  data  quality;  technical  problems;  or  competitive  pressures.  We
compete  against  many  other  commercial  real  estate  information,  analytics,  and  marketing  service  providers  for  business,  including  competitors  that  offer  their
services through rapidly changing methods of delivering real estate information. If clients cancel services or decide not to renew their subscription agreements, and
we do not sell new services to our existing clients or attract new clients, then our renewal rate, net new sales and revenues may decline or fail to meet expectations.

We may not be able to successfully introduce new or upgraded information, analytics and online marketplace services or combine or shift focus from services
with less demand, which could decrease our revenues and our profitability. Our future business and financial success will depend on our ability to continue to
anticipate  the needs of customers and potential customers, and to successfully introduce new and upgraded services into the marketplace.  To be successful, we
must be able to quickly adapt to changes in the industry, as well as rapid technological changes by continually enhancing our information, analytics and online
marketplace services. Developing new services and upgrades to services, as well as integrating and coordinating current services, imposes heavy burdens on our
systems  department,  product  development  team,  management  and  researchers.  The  processes  are  costly,  and  our  efforts  to  develop,  integrate  and  enhance  our
services  may  not  be  successful.  In  addition,  successfully  launching  and  selling  a  new  or  upgraded  service  puts  additional  strain  on  our  sales  and  marketing
resources. If we are unsuccessful in obtaining greater market share or in obtaining widespread adoption of new or upgraded services, we may not be able to offset
the expenses associated with the launch and marketing of the new or upgraded service, which could have a material adverse effect on our financial results. For
example,  to  generate  brand  awareness  and  site  traffic  for  our  Apartments.com  network  of  rental  websites,  we  invest  significant  resources  in  a  multi-channel
marketing campaign. If the marketing campaign does not continue to increase brand awareness, site traffic and/or revenues, it could have an adverse effect on our
financial results.

If  we  are  unable  to  develop  new  or  upgraded  services  or  decide  to  combine,  shift  focus  from,  or  phase  out  a  service,  then  our  customers  may  choose  a
competitive  service  over ours and our revenues may decline  and our profitability  may be reduced. If we incur significant  costs in developing new or upgraded
services or combining and coordinating existing services, if we are not successful in marketing and selling these new services or upgrades, or if our customers fail
to  accept  these  new  or  combined  and  coordinating  services,  then  there  could  be  a  material  adverse  effect  on  our  results  of  operations  due  to  a  decrease  of  our
revenues and a reduction of our profitability. In addition, as we integrate acquired businesses, we continue to assess which services we believe will best meet the
needs of our customers. If we eliminate or phase out a service and are not able to offer and successfully market and sell an alternative service, our revenue may
decrease, which could have a material adverse effect on our results of operations.

If we do not invest in product development and provide services that are attractive to our marketplace users and to our advertisers, our business could be
adversely  affected.  Our  success  depends  on  our  continued  improvements  to  provide  services  that  make  our  marketplaces  useful  for  users  and  attractive  to  our
advertisers.  As  a  result,  we  must  continually  invest  resources  in  research  and  development  to  improve  the  appeal  and  comprehensiveness  of  our  services  and
effectively incorporate new technologies. If we are unable to provide services that users want, then users may become dissatisfied and use competitors’ websites. If
we are  unable  to continue  offering  innovative  services,  we may  be  unable  to attract  additional  users and  advertisers  or retain  our current  users  and advertisers,
which could harm our business, results of operations and financial condition.

A downturn or consolidation in the commercial real estate industry may decrease customer demand for our services. The commercial real estate market may
be adversely impacted by many different factors, including lower than expected job growth or job losses resulting in reduced real estate demand; rising interest
rates and slowing transaction volumes that negatively impact investment returns; excessive speculative new construction in localized markets resulting in increased
vacancy rates and diminished

17

 
rent growth; and unanticipated disasters and other adverse events such as slowing of the growth in the working age population resulting in reduced demand for all
types of real estate. A reversal of improvements in the commercial real estate industry’s leasing activity and absorption rates or a downturn in the commercial real
estate market may affect our ability to generate revenues and may lead to more cancellations by our current or future customers, either of which could cause our
revenues or our revenue growth rate to decline and reduce our profitability. A depressed commercial real estate market has a negative impact on our core customer
base, which could decrease demand for our information, analytics and online marketplaces.  Also, companies in this industry may consolidate, often in order to
reduce expenses. Consolidation, or other cost-cutting measures by our customers, may lead to cancellations of our information, analytics and online marketplace
services by our customers, reduce the number of our existing clients, reduce the size of our target market or increase our clients’ bargaining power, all of which
could cause our revenues to decline and reduce our profitability. If cancellations, reductions of services, and failures to pay increase, and we are unable to offset the
resulting decrease in revenues by increasing sales to new or existing customers, our revenues may decline or grow at lower rates.

Negative  general  economic  conditions  could  increase  our  expenses  and  reduce  our  revenues.  Our  business  and  the  commercial  real  estate  industry  are
particularly affected by negative trends in the general economy. The success of our business depends on a number of factors relating to general global, national,
regional and local economic conditions, including perceived and actual economic conditions, recessions, inflation, deflation, exchange rates, interest rates, taxation
policies, availability of credit, employment levels, wage and salary levels, and uncertainty from the expected discontinuance of LIBOR and the transition to any
other  interest  rate  benchmark.  Negative  general  economic  conditions  could  adversely  affect  our  business  by  reducing  our  revenues  and  profitability.  If  we
experience greater cancellations or reductions of services and failures to timely pay, and we do not acquire new clients or sell new services to our existing clients,
our revenues may decline and our financial position would be adversely affected. Adverse national and global economic events, as well as any significant terrorist
attack,  are  likely  to  have  a  dampening  effect  on  the  economy  in  general,  which  could  negatively  affect  our  financial  performance  and  our  stock  price.  Further
actions  or inactions  of the U.S. or other  major  national  governments,  including  "Brexit", may  also impact  economic  conditions,  which could result in financial
market disruptions or an economic downtown. Market disruptions may also contribute to extreme price and volume fluctuations in the stock market that may affect
our stock price for reasons unrelated to our operating performance. In addition, a significant increase in inflation could increase our expenses more rapidly than
expected,  the  effect  of  which  may  not  be  offset  by  corresponding  increases  in  revenue.  Conversely,  deflation  resulting  in  a  decline  of  prices  could  reduce  our
revenues. In the current economic environment, it is difficult to predict whether we will experience significant inflation or deflation in the near future. A significant
increase  in  either  could  have  an  adverse  effect  on  our  results  of  operations.  See  the  risk  factor  below  titled  “The  economic  effects  of  “Brexit”  may  affect
relationships with existing and future customers and could have an adverse impact on our business and operating results” for further discussion of risks related to
Brexit.

If we are unable to hire qualified persons for, or retain and continue to develop, our sales force, or if our sales force is unproductive, our revenues could be
adversely affected. In order to support revenues and future revenue growth, we need to continue to develop, train and retain our sales force. Our ability to build and
develop  a  strong  sales  force  may  be  affected  by  a  number  of  factors,  including:  our  ability  to  attract,  integrate  and  motivate  sales  personnel;  our  ability  to
effectively  train  our  sales  force;  the  ability  of  our  sales  force  to  sell  an  increased  number  and  different  types  of  services;  our  ability  to  manage  effectively  an
outbound  telesales  group;  the  length  of  time  it  takes  new  sales  personnel  to  become  productive;  the  competition  we  face  from  other  companies  in  hiring  and
retaining sales personnel; our ability to effectively  structure our sales force; and our ability to effectively  manage a multi-location  sales organization, including
field sales personnel. If we are unable to hire qualified sales personnel and develop and retain the members of our sales force, including sales force management, or
if our sales force is unproductive, our revenues or growth rate could decline and our expenses could increase.

We  may  not  be  able  to  compete  successfully  against  existing  or  future  competitors  in  attracting  advertisers,  which  could  harm  our  business,  results  of
operations and financial condition. We compete to attract advertisers. Our competition for advertisers may have significant brand recognition as well as greater
numbers  of  direct  sales  personnel  than  we  have  and  may  generate  more  web  traffic  than  we  do,  which  may  provide  a  competitive  advantage.  To  compete
successfully for advertisers against future and existing competitors, we must continue to invest resources in developing our advertising platform and proving the
effectiveness and relevance of our advertising services. Pressure from competitors seeking to acquire a greater share of our advertisers’ overall marketing budget
could  adversely  affect  our  pricing  and  margins,  lower  our  revenue,  and  increase  our  research  and  development  and  marketing  expenses.  If  we  are  unable  to
compete successfully against our existing or future competitors, our business, results of operations or financial condition could be adversely affected.

We may be unable to increase awareness of our brands, including CoStar, LoopNet, Apartments.com, BizBuySell and LandsofAmerica, which could adversely
affect our business. We rely heavily on our brands, which we believe are key assets of our company. Awareness and differentiation of our brands are important for
attracting and expanding the number of users of, and subscribers to, our online marketplaces, such as LoopNet, the Apartments.com network of rental websites,
CoStar Showcase, and the Land.com network of rural lands for-sale. We expect to increase our investments in sales and marketing in 2020 as we seek

18

to grow the numbers of subscribers to, and advertisers on, our marketplaces. Our methods of advertising may not be successful in increasing brand awareness or,
ultimately, be cost-effective. If we are unable to maintain or enhance user and advertiser awareness of our brands, or if we are unable to recover our marketing and
advertising  costs  through  increased  usage  of  our  services  and  increased  advertising  on  our  websites,  our  business,  results  of  operations  and  financial  condition
could be adversely affected.

Our  internal  and  external  investments  may  place  downward  pressure  on  our  operating  margins.  We  continue  to  invest  in  our  business,  including  internal
investments in product development to expand the breadth and depth of services we provide to our customers and external investments in sales and marketing to
generate  brand  awareness.  Our  investment  strategy  is  intended  to  increase  our  revenue  growth  in  the  future.  Our operating  margins  may  experience  downward
pressure in the short term as a result of these investments. Furthermore,  our investments  may not have their intended effect  or produce the expected results. In
addition, our external investments, such as capitalized commissions, may lose value and we may incur impairment charges with respect to such investments. Such
impairment charges may negatively impact our profitability. If we are unable to successfully execute our investment strategy or if we fail to adequately anticipate
and address potential problems, we may experience decreases in our revenues and operating margins.

We rely on Internet search engines to drive traffic to our websites. If Internet search engines do not prominently feature our websites on the search engine
results page, traffic to our websites would decrease and our business could be adversely affected. Google, Bing, DuckDuckGo and other Internet search engines
drive traffic to our websites, including CoStar.com, the Apartments.com network of rental websites, the LoopNet.com network of commercial real estate websites,
the BizBuySell.com network of business for-sale websites and the Land.com network of land for-sale websites. For example, when a user enters in a search query
for an apartment building name or address into an Internet search engine, the Internet search engine’s ranking of our Apartments.com webpages will determine
how prominently such webpages are displayed on the search engine results page. Our ability to maintain prominent search result rankings and positioning is not
entirely within our control. Our competitors’ Search Engine Optimization (SEO) and Search Engine Marketing (SEM) efforts may result in webpages from their
websites  receiving  higher  rankings  than  the  webpages  from  our  websites.  Internet  search  engines  could  revise  their  algorithms  and  methodologies  in  ways  that
would  adversely  affect  our  search  result  rankings.  Internet  search  engine  providers  could  form  partnerships  or  enter  into  other  business  relationships  with  our
competitors resulting in competitors’ sites receiving higher search result rankings. Internet search engines are increasingly placing alternative search features (such
as featured snippets, local map results and other immersive experiences) on the search engine results page above or more prominently than search engine results. If
our search result rankings are not prominently displayed, traffic  to our websites may decline which could slow the growth of our user base. Our websites have
experienced fluctuations in search result rankings in the past, and we anticipate similar fluctuations will occur in the future. If we experience a material reduction in
the number of users directed to our websites through Internet search engines, our business, results of operations and financial condition could be adversely affected.

Competition  could  render  our  services  uncompetitive  and  reduce  our  profitability.  The  markets  for  information  systems  and  services  and  for  online
marketplaces  in  general  are  highly  competitive  and  rapidly  changing.  Competition  in  these  markets  may  increase  further  if  economic  conditions  or  other
circumstances cause customer bases and customer spending to decrease and service providers to compete for fewer customer resources. Our existing competitors,
or future competitors, may have greater name recognition, larger customer bases, better technology or data, lower prices, easier access to data, greater user traffic
or greater financial, technical or marketing resources than we have. Our competitors may be able to undertake more effective marketing campaigns, obtain more
data,  adopt  more  aggressive  pricing  policies,  make  more  attractive  offers  to  potential  employees,  subscribers,  advertisers,  distribution  partners  and  content
providers or may be able to respond more quickly to new or emerging technologies or changes in user requirements. If we are unable to retain customers or obtain
new customers, our revenues could decline. Increased competition could result in lower revenues and higher expenses, which would reduce our profitability.

If we are unable to maintain or increase traffic to our marketplaces, our business and operating results could be adversely affected. Our ability to generate
revenues  from  our  marketplace  businesses  depends,  in  part,  on  our  ability  to  attract  users  to  our  websites.  If  we  fail  to  maintain  or  increase  traffic  to  our
marketplaces,  our  ability  to  acquire  additional  subscribers  or  advertisers  and  deliver  leads  to  and  retain  existing  subscribers  and  advertisers  could  be  adversely
affected. Our marketing expenses may increase in connection with our efforts to maintain or increase traffic to our websites. Our efforts to maintain or generate
additional traffic to our marketplaces may not be successful. Even if we are able to attract additional users, increases in our operating expenses could negatively
impact our operating results if we are unable to generate more revenues through increased sales of subscriptions to our marketplace products. We face competition
to attract users to our marketplace websites. Our existing and potential competitors include companies that could devote greater technical and other resources than
we have available to provide services that users might view as superior to our offerings. Any of our future or existing competitors may introduce different solutions
that attract users away from our services or provide solutions similar to our own that have the advantage of better branding or marketing resources. If we are unable
to increase traffic to our marketplaces, or if we are unable to generate enough additional revenues to offset increases in expenses related to increasing traffic to our
marketplaces, our business and operating results could be adversely affected.

19

If  real  estate  professionals  or  other  advertisers  reduce  or  cancel  their  advertising  spending  with  us  and  we  are  unable  to  attract  new  advertisers,  our
operating results would be harmed. Our marketplace businesses, including LoopNet, the Apartments.com network of rental websites, and the Land.com network of
rural  lands  for-sale,  depend  on  advertising  revenues  generated  primarily  through  sales  to  persons  in  the  real  estate  industry,  including  property  managers  and
owners  and  other  advertisers.  Our  ability  to  attract  and  retain  advertisers,  and  ultimately  to  generate  advertising  revenue,  depends  on  a  number  of  factors,
including:

•
•
•
•
•

Increasing the number of unique visitors to, and users of, our websites and mobile applications;
The quantity and quality of the leads that we provide to our advertisers;
The success of any marketing and product development efforts directed at attracting additional users and advertisers to our marketplaces;
Keeping pace with changes in technology and with our competitors; and
Offering an attractive return on investment to our advertisers for their advertising dollars spent with us.

Further,  with  respect  to  the  Apartments.com  network  of  rental  websites,  our  ability  to  attract  and  retain  advertisers  also  depends  on  the  current  apartment

rental market and apartment vacancy rates. If vacancy rates are too high or too low, advertisers may not need to utilize our marketplace services.

Many of the advertisers who advertise on our marketplaces do not have long-term contracts. These advertisers could choose to modify or discontinue their
relationships  with  us  with  little  or  no  advance  notice.  In  addition,  as  existing  subscriptions  for  advertising  expire,  we  may  not  be  successful  in  renewing  these
subscriptions or securing new subscriptions. We may not succeed in retaining existing advertisers’ spending or capturing a greater share of such spending if we are
unable  to  convince  advertisers  of  the  effectiveness  of  our  services  as  compared  to  alternatives.  In  addition,  future  changes  to  our  pricing  methodology  for
advertising services may cause advertisers to reduce or discontinue their advertising with us. If current advertisers reduce or end their advertising spending with us
and we are unable to attract new advertisers, our advertising revenues and business, results of operations and financial condition could be adversely affected.

If we are not able to successfully identify, finance, integrate and/or manage costs related to acquisitions, our business operations and financial position could
be adversely affected. We have expanded our markets and services in part through acquisitions of complementary businesses, services, databases and technologies,
and expect to continue to do so in the future. Our strategy to acquire complementary companies or assets depends on our ability to identify, and the availability of,
suitable acquisition candidates. We are likely to incur costs in connection with proposed acquisitions, but may ultimately be unable or unwilling to consummate
any  particular  proposed  transaction  for  various  reasons.  In  addition,  acquisitions  involve  numerous  risks,  including  risks  that  we  will  not  be  able  to  realize  or
capitalize  on  synergies  created  through  combinations;  manage  the  integration  of  personnel  and  products  or  services;  manage  the  integration  of  acquired
infrastructure  and  controls;  control  potential  increases  in  operating  costs;  manage  geographically  remote  operations;  maintain  management’s  attention  on  other
business concerns and avoid potential disruptions in ongoing operations during an acquisition process or integration efforts; successfully enter markets and sectors
in which we have either limited or no direct experience, including foreign markets whose practices, regulations or laws may pose increased risk; and retain key
employees, clients or vendors and other business partners of the acquired companies. We may not successfully integrate acquired businesses or assets and may not
achieve anticipated benefits of an acquisition, including expected synergies.  For example, we may be unable to close the RentPath acquisition when or as expected
and we may be unable to fully integrate STR with CoStar when and as expected.

We often incur severance costs and other integration costs post-acquisition, such as IT integration expenses and costs related to the renegotiation of redundant
vendor agreements. Costs in connection with acquisitions and integrations may be higher than expected, and we may also incur unanticipated acquisition-related
costs. These costs could adversely affect our financial condition, results of operation or prospects of the combined business.

External factors, such as compliance with laws and regulations, and shifting market preferences, may also impact the successful integration of an acquired
business.    An  acquired  business  could  strain  our  system  of  internal  controls  and  diminish  its  effectiveness,  including  as  a  result  of  unsuccessful  integration  or
because integration with our existing systems puts additional stress on our core infrastructure. Acquisitions could result in dilutive issuances of equity securities,
the incurrence of debt, one-time write-offs of goodwill and substantial amortization expenses of other intangible assets. We may be unable to obtain financing on
favorable terms, or at all, if necessary to finance future acquisitions, making it impossible or more costly to complete future acquisitions. If we are able to obtain
financing, the terms may be onerous and restrict our operations. Further, certain acquisitions may be subject to regulatory approval, which can be time consuming
and costly to obtain or may be denied.  If regulatory approval is obtained, the terms of any such approval may impose limitations on our ongoing operations or
require us to divest assets or lines of business.

20

If regulatory approval is denied, we may incur significant, additional costs payable to an acquisition target as a result of failure to close the transaction.

Our actual or perceived failure to comply with privacy laws and standards could adversely affect our business, financial condition and results of operations.
We  depend  on  information  technology  networks  and  systems  to  process,  transmit  and  store  electronic  information  and  to  communicate  between  our  locations
around  the  world  and  with  our  clients  and  vendors.  We  collect,  use  and  disclose  personally  identifiable  information,  including  among  other  things  names,
addresses,  phone  numbers  and  email  addresses.  We  collect,  store  and  use  biometric  data  and  sensitive  or  confidential  transaction  and  account  information.  In
addition, we collect personal information from tenants and landlords, including social security numbers, state or federally issued identification numbers, dates of
birth,  financial  information  and  documents,  employment  information,  background  checks  and  credit  scores,  to  facilitate  the  apartment  rental  application  and
payment process between a renter and property manager. As a result, we are subject to a variety of state, national, and international laws and regulations that apply
to the collection, use, retention, protection, disclosure, transfer and other processing of personal data, including the Fair Credit Reporting Act, the General Data
Protection Regulation (GDPR) and California Consumer Privacy Act (CCPA). Laws and regulations related to privacy and data protection are evolving, with new
or modified laws and regulations proposed and implemented frequently and existing laws and regulations subject to new or different interpretations. For example,
in  2016,  the  EU  formally  adopted  the  GDPR,  which  was  implemented  in  all  EU  member  states  effective  May  25,  2018  and  replaced  the  EU  Data  Protection
Directive. The GDPR introduced new data protection requirements in the EU and imposes substantial fines for breaches of the data protection rules. The GDPR
increased our responsibility and liability in relation to personal data that we process. We continue to assess our compliance with GDPR in light of guidance from
data protection authorities, evolving best practices and evolving regulations and we may need to put in place additional mechanisms to ensure compliance with the
new EU data protection rules. The CCPA, which became effective on January 1, 2020, expands the rights of California residents to access and require deletion of
their  personal  information,  opt  out  of  certain  personal  information  sharing  and  receive  detailed  information  about  how  their  personal  information  is  used.  The
CCPA also provides for civil penalties for violations, as well as a private right of action for data breaches that may increase data breach litigation. Any failure to
comply with the rules arising from the GDPR and related national laws of EU member states, CCPA and other privacy or data protection laws adopted by other
jurisdictions, could lead to government enforcement actions and significant penalties against us, and could adversely affect our business, financial condition, cash
flows and results of operations. Compliance with any of the foregoing laws and regulations can be costly, can delay or impede the development of new products,
and may require us to change the way we operate. We may incur substantial fines if we violate any laws or regulations relating to the collection or use of personal
information.

Our  actual  or  alleged  failure  to  comply  with  applicable  privacy  or  data  security  laws,  regulations  and  policies,  or  to  protect  personal  data,  could  result  in
enforcement  actions  and  significant  penalties  against  us,  which  could  result  in  negative  publicity,  increase  our  operating  costs,  subject  us  to  claims  or  other
remedies and have a material adverse effect on our business, financial condition and results of operations.

Because the interpretation and application of many privacy and data protection laws are uncertain, it is possible that these laws may be interpreted and applied
in a manner that is inconsistent with our existing data management practices or the features of our products. If so, in addition to the possibility of fines, lawsuits
and other claims and penalties, we could be required to fundamentally change our business activities and practices or modify our products, which could harm our
business.

We expect that there will continue to be new proposed laws, regulations and industry standards concerning privacy, data protection and information security in
the United States and other jurisdictions, and we cannot determine the impact such future laws, regulations and standards may have on our business. Our policies
concerning the collection, use and disclosure of personally identifiable information are described on our websites. We could be subject to legal claims, government
action, harm to our reputation or incur significant remediation costs if we experience a security breach or our practices fail, or are seen as failing, to comply with
our policies or with applicable laws concerning personally identifiable information.

Concern regarding our use of the personal information collected on our websites or collected when performing our services could keep prospective customers
from subscribing to our services. Industry-wide incidents or incidents with respect to our websites, including misappropriation of third-party information, security
breaches or changes in industry standards, regulations or laws, could deter people from using the Internet or our websites to conduct transactions that involve the
transmission of confidential information, which could harm our business.

Cyberattacks  and  security  vulnerabilities  could  result  in  serious  harm  to  our  reputation,  business,  and  financial  condition.  As  stated  above,  our  business
involves the collection, storage, processing and transmission of customers’ personal data. We also collect, store and process employee personal data. An increasing
number of organizations, including large merchants, businesses, technology companies and financial institutions, as well as government institutions, have disclosed
breaches of their information

21

security systems, some of which have involved sophisticated and highly targeted attacks, including on their websites, mobile applications, and infrastructure.

The techniques used to obtain unauthorized, improper or illegal access to a target's systems, data or customers' data, disable or degrade services, or sabotage
systems  are  constantly  evolving  and  have  become  increasingly  complex  and  sophisticated,  may  be  difficult  to  detect  quickly  and  often  are  not  recognized  or
detected until after they have been launched against a target. We expect that unauthorized parties will continue to attempt to gain access to our systems or facilities
through various means, including hacking into our systems or facilities or those of our customers or vendors, or attempting to fraudulently induce (for example,
through spear phishing attacks or social engineering) our employees, customers, vendors or other users of our systems into disclosing user names, passwords, or
other  sensitive  information,  which  may  in  turn  be  used  to  access  our  information  technology  systems.  Numerous  and  evolving  cybersecurity  threats,  including
advanced and persisting cyberattacks, phishing and social engineering schemes, could compromise the confidentiality, availability, and integrity of the data in our
systems. Our cybersecurity programs and efforts to protect our systems and data, and to prevent, detect and respond to data security incidents, may not prevent
these threats  or provide security.  Further, the security  measures  and procedures  our customers,  vendors and other users of our systems have in place to protect
sensitive consumer data and other information may not be successful or sufficient to counter all data breaches, cyberattacks or system failures.

Our information technology and infrastructure may be vulnerable to cyberattacks or security breaches, and third parties may be able to access our customers’
or  employees’  personal  or  proprietary  information  that  is  stored  on  or  accessible  through  those  systems.  We  have  experienced  from  time  to  time,  and  may
experience  in  the  future,  breaches  of  our  security  measures  due  to  human  error,  malfeasance,  system  errors  or  vulnerabilities  or  other  irregularities.  Actual  or
perceived breaches of our security could, among other things:

•
•
•
•
•
•
•
•
•
•

Interrupt our operations,
Result in our systems or services being unavailable,
Result in improper disclosures of data,
Materially harm our reputation and brands,
Result in significant regulatory scrutiny and legal and financial exposure,
Cause us to incur significant remediation costs,
Lead to loss of customer confidence in, or decreased use of, our products and services,
Divert the attention of management from the operation of our business,
Result in significant contractual penalties or other payments as a result of third-party losses or claims, and
Adversely affect our business and result of operations.

In  addition,  any  cyberattacks  or  data  security  breaches  affecting  companies  that  we  acquire  or  our  customers  or  vendors  (including  data  center  and  cloud
computing  providers)  could  have  similar  negative  effects  on  our  business.  The  coverage  under  our  insurance  policies  may  not  be  adequate  to  reimburse  us  for
losses caused by security breaches.

We are subject to a number of risks related to acceptance of credit cards and debit cards for customer payments. We accept payments for our services through
credit and debit card transactions. For credit and debit card payments, we pay interchange and other fees, which may increase over time. An increase in those fees
may require us to increase the prices we charge and would increase our cost of revenues, either of which could harm our business, financial condition or results of
operations.

We depend  on processing  vendors  to complete  credit  and debit  card  transactions.  If  we  or our processing  vendors fail  to  maintain  adequate  systems  for the
authorization  and  processing  of  credit  card  transactions,  it  could  cause  one  or  more  of  the  major  credit  card  companies  to  disallow  our  continued  use  of  their
payment products. We could lose customers if we are not able to continue to use payment products of the major credit card companies. In addition, if the systems
for the authorization and processing of credit card transactions fail to work properly and, as a result, we do not charge our customers’ credit cards on a timely basis
or at all, our business, revenue, results of operations and financial condition could be harmed.     

We are also subject to payment card association operating rules, certification requirements and rules governing electronic funds transfers, which could change
or  be  reinterpreted  in  ways  that  make  it  more  difficult  for  us  to  comply.  We  are  required  to  comply  with  payment  card  industry  security  standards.  Failing  to
comply  with  those  standards  may  violate  payment  card  association  operating  rules,  federal  and  state  laws  and  regulations,  and  the  terms  of  our  contracts  with
payment processors. Any failure to comply also may subject us to fines, penalties, damages and civil liability, and may result in the loss of our ability to accept
credit and debit card payments. Further, there is no guarantee that such compliance will prevent illegal or improper use of our payment systems or the theft, loss, or
misuse of data pertaining to credit and debit cards, cardholders and transactions. If we fail to adequately control fraudulent credit card transactions, we may face
civil  liability,  diminished  public  perception  of  our  security  measures  and  significantly  higher  credit  card-related  costs,  each  of  which  could  harm  our  business,
results of operations and financial condition.

22

If we are unable to maintain our chargeback rate or refund rates at acceptable levels, our processing vendors may increase our transaction fees or terminate
their relationships with us. Any increases in our credit and debit card fees could harm our results of operations, particularly if we elect not to raise our rates for our
services to offset the increase. The termination of our ability to process payments on any major credit or debit card would significantly impair our ability to operate
our business.

Technical problems or disruptions that affect either our customers’ ability to access our services, or the software, internal applications, database and network
systems  underlying  our  services,  could  damage  our  reputation  and  brands  and  lead  to  reduced  demand  for  our  information,  analytics  and  online  marketplace
services,  lower  revenues  and  increased  costs.  Our  business,  brands  and  reputation  depend  upon  the  satisfactory  performance,  reliability  and  availability  of  our
websites,  the  Internet  and  our  service  providers.  Interruptions  in  these  systems,  whether  due  to  system  failures,  computer  viruses,  software  errors,  physical  or
electronic break-ins, or malicious hacks or attacks on our systems (such as denial of service attacks), could affect the security and availability of our services on
our mobile applications and our websites and prevent or inhibit the ability of users to access our services. Our operations also depend on our ability to protect our
databases, computers and software, telecommunications equipment and facilities against damage from potential dangers such as fire, flood, power loss, security
breaches, computer viruses, telecommunications failures, terrorist attacks, acts of war, electronic and physical break-ins, computer viruses, earthquakes and similar
events. Our users rely on our services when conducting their own businesses. Disruptions in, or reductions in ability to access, our services for whatever reason
could  damage  our  users’  businesses,  harm  our  reputation,  result  in  additional  costs  or  result  in  reduced  demand  for  our  information,  analytics  and  online
marketplace services, any of which could harm our business, results of operations and financial condition.

In  addition,  the  software,  internal  applications  and  systems  underlying  our  services  are  complex  and  may  not  be  error-free.  Our  careful  development  and
testing may not be sufficient to ensure that we will not encounter technical problems when we attempt to enhance our software, internal applications and systems.
Any inefficiencies, errors or technical problems with our software, internal applications and systems could reduce the quality of our services or interfere with our
customers’ access to our information, analytics  and online marketplaces,  which could reduce the demand for our services,  lower our revenues and increase our
costs.

The majority of the communications, network and computer hardware used to operate our mobile applications and websites are located at facilities in Virginia
and California. We do not own or control the operation of certain of these facilities. Our systems and operations are vulnerable to damage or interruption from fire,
flood, power loss, security breaches, computer viruses, telecommunications failure, terrorist attacks, acts of war, electronic and physical break-ins, earthquakes and
similar events. These risks may be increased with respect to operations housed at facilities we do not own or control. The occurrence of any of the foregoing events
could result in damage to our systems and hardware or could cause them to fail completely, and our insurance may not cover such events or may be insufficient to
compensate us for losses that may occur.

A failure of our systems at any site could result in reduced functionality for our users, and a total failure of our systems could cause our mobile applications or
websites to be inaccessible. Problems faced or caused by our information technology service providers, including content distribution service providers, private
network  providers,  Internet  providers  and  third-party  web-hosting  providers,  or  with  the  systems  by  which  they  allocate  capacity  among  their  customers  (as
applicable),  could  adversely  affect  the  experience  of  our  users.  Any  financial  difficulties,  such  as  bankruptcy  reorganization,  faced  by  these  third-party  service
providers or any of the service providers with whom they contract may have negative effects on our business, the nature and extent of which are difficult to predict.
If our third-party service providers are unable to keep up with our growing needs for capacity, our business could be harmed. In addition, if distribution channels
for our mobile applications experience disruptions, such disruptions could adversely affect the ability of users and potential users to access or update our mobile
applications, which could harm our business.

Our business interruption insurance may not cover certain events or may be insufficient to compensate us for the potentially significant losses, including the
potential harm to the future growth of our business, which may result from interruptions in our service  as a result of system failures  or malicious  attacks. Any
errors, defects, disruptions or other performance problems with our services could harm our reputation, business, results of operations and financial condition.

If we are not able to obtain and maintain accurate, comprehensive or reliable data, we could experience reduced demand for our information, analytics and
online  marketplace  services.  Our  success  depends  on  our  clients’  confidence  in  the  comprehensiveness,  accuracy  and  reliability  of  the  data  and  analysis  we
provide. The task of establishing and maintaining accurate and reliable data and analysis is challenging. If our data, including the data we obtain from third parties
or directly from brokers through the Marketing Center feature on CoStar and LoopNet, or analysis is not current, accurate, comprehensive or reliable, we could
experience reduced demand for our services or legal claims by our customers, which could result in lower revenues and higher expenses.

23

Market volatility may have an adverse effect on our stock price. The trading price of our common stock has fluctuated widely in the past, and we expect that it
will continue to fluctuate in the future. The price could fluctuate widely based on numerous factors, including: economic factors or conditions; quarter-to-quarter
variations  in  our  operating  results;  changes  in  analysts’  estimates  of  our  earnings;  announcements  by  us  or  our  competitors  of  technological  innovations,  new
services,  or  other  significant  or  strategic  information;  general  conditions  in  the  commercial  real  estate  industry;  general  conditions  of  local,  national  or  global
economies; developments or disputes concerning copyrights or proprietary rights or other legal proceedings; and regulatory developments. In addition, the stock
market in general, and the shares of Internet-related and other technology companies in particular, have historically experienced extreme price fluctuations. This
volatility has had a substantial effect on the market prices of securities issued by many companies for reasons unrelated to the operating performance of the specific
companies and may have the same effect on the market price of our common stock.

If we are unable to enforce or defend our ownership and use of intellectual property, our business, brands, competitive position and operating results could be
harmed. The success of our business depends in large part on our intellectual property, including intellectual property involved in our methodologies, database,
services and software. We rely on a combination of trademark, trade secret, patent, copyright and other laws, nondisclosure and noncompetition provisions, license
agreements and other contractual provisions and technical measures to protect our intellectual property rights. However, current law may not provide for adequate
protection of our databases and the actual data. In addition, legal standards relating to the validity, enforceability and scope of protection of proprietary rights in
Internet-related businesses are uncertain and evolving, and changes in these standards may adversely impact the viability or value of our proprietary rights. We find
our proprietary content on competitors' sites. If we are not successful in protecting our intellectual property, including our content, our brands and our business,
results of operations and financial condition could be harmed. The same would be true if a court found that our services infringe other persons’ intellectual property
rights. Any intellectual property lawsuits or threatened lawsuits in which we are involved, either as a plaintiff or as a defendant, could cost us a significant amount
of time and money and distract management’s attention from operating our business. In addition, if we do not prevail on an intellectual property claim, this could
result in a change to our methodology or information, analytics and online marketplace services and could reduce our profitability.

Effective trademark, trade secret, patent, and copyright protection may not be available in every country in which our services may be provided. The laws of
certain countries do not protect proprietary rights to the same extent as the laws of the United States and, therefore, in certain jurisdictions, we may be unable to
protect  our  intellectual  property  and  our  proprietary  technology  adequately  against  unauthorized  third-party  copying  or  use,  which  could  harm  our  competitive
position.

We  seek  to  enforce  our  rights  against  people  and  entities  that  infringe  our  intellectual  property,  including  through  legal  action.  Taking  such  action  may  be
costly, and we cannot ensure that such actions will be successful. Any increase in the unauthorized use of our intellectual property could make it more expensive
for us to do business and harm our results of operations or financial condition.

We may not be able to successfully halt the operation of websites that aggregate our data, as well as data from other companies, such as copycat websites that
may misappropriate our data. Third parties may misappropriate our data through website scraping, robots or other means and aggregate this data on their websites
with data from other companies. In addition, “copycat” websites may misappropriate data on our website and attempt to imitate our brands or the functionality of
our website. We may not be able to detect all such websites in a timely manner and, even if we could, technological and legal measures may be insufficient to stop
their operations. In some cases, particularly in the case of websites operating outside of the U.S., our available remedies may not be adequate to protect us against
the misappropriation of our data. Regardless of whether we can successfully enforce our rights against the operators of these websites, any measures that we may
take could require us to expend significant financial or other resources.

Third  party  claims,  litigation  or  government  investigations  to  which  we  are  subject  or  in  which  we  become  involved,  regardless  of  their  merit,  may
significantly  increase our expenses and adversely affect our stock price. We  could  be subject  to  third  party  claims,  lawsuits,  or  government  investigations  into
whether our business practices comport with applicable law, including antitrust law. Regardless of the merit of such claims or investigations, defending against
them  could  cost  us  a  significant  amount  of  time  and  money,  result  in  negative  publicity,  and/or  adversely  affect  our  stock  price.  In  addition,  if  any  claims  are
decided  against  us  or  if  a  settlement  requires  us  to  pay  a  large  monetary  amount  or  take  other  action  that  materially  restricts  or  impedes  our  operations,  our
profitability could be significantly reduced and our financial position could be adversely affected.

We may be subject to legal liability for collecting, displaying or distributing information. Because the content in our database is collected from various sources
and distributed to others, we may be subject to claims for breach of contract, defamation, negligence, unfair competition or copyright or trademark infringement or
claims based on other theories. We could also be subject to claims based upon the content that is accessible from our website through links to other websites or
information on our website supplied by third parties. We could also be subject to claims that the collection or provision of certain information breached laws

24

and regulations relating to privacy and data protection. Even if these claims do not result in liability to us, we could incur significant costs in investigating and
defending against any claims and we could be subject to public notice requirements that may affect our reputation in the marketplace. Our potential liability for
information distributed by us to others could require us to implement measures to reduce our exposure to such liability, which may require us to expend substantial
resources and limit the attractiveness of our information, analytics and online marketplaces to users.

Our business depends on retaining and attracting highly capable management and operating personnel. Our success depends in large part on our ability to
retain  and  attract  management  and  operating  personnel,  including  our  President  and  Chief  Executive  Officer,  Andrew  Florance,  and  our  other  officers  and  key
employees. Our business requires highly skilled technical, sales, management, web product and development, marketing and research personnel, who are in high
demand and are often subject to competing offers. To retain and attract key personnel, we use various measures, including employment agreements, awards under a
stock  incentive  plan  and  incentive  bonuses  for  key  employees.  These  measures  may  not  be  enough  to  retain  and  attract  the  personnel  we  need  or  to  offset  the
impact on our business of the loss of the services of Mr. Florance or other key officers or employees. 

An  impairment  in  the  carrying  value  of  goodwill  could  negatively  impact  our  consolidated  results  of  operations  and  net  worth. Goodwill  and  identifiable
intangible assets not subject to amortization are tested annually by each reporting unit on October 1 of each year for impairment and are tested for impairment
more frequently based upon the existence of one or more indicators. We assess the impairment of long-lived assets, identifiable intangibles and goodwill whenever
events or changes in circumstances indicate that the carrying value may not be recoverable. Judgments made by management relate to the expected useful lives of
long-lived  assets and our ability  to realize  undiscounted  cash flows of the carrying  amounts of such assets. The accuracy  of these judgments may be adversely
affected by several factors, including the factors listed below:

•
•
•
•

Significant underperformance relative to historical or projected future operating results;
Significant changes in the manner of our use of acquired assets or the strategy for our overall business;
Significant negative industry or economic trends; or
Significant decline in our market capitalization relative to net book value for a sustained period.

These types of events or indicators and the resulting impairment analysis could result in goodwill impairment charges in the future, which would reduce our
profitability.  Impairment  charges  could  negatively  affect  our  financial  results  in  the  periods  of  such  charges,  which  may  reduce  our  profitability.  As  of
December  31,  2019,  we  had  approximately  $1.9  billion of  goodwill,  including  approximately  $1.7  billion in  our  North  America  operating  segment  and
approximately $144 million in our International operating segment.  

If we are unable to obtain or retain listings from commercial real estate brokers, agents, property owners and apartment property managers, our commercial
real estate ("CRE") marketplace services, including but not limited to the LoopNet.com network of commercial real estate websites, the Apartments.com network of
rental websites, and the Land.com network of land for-sale websites, could be less attractive to current or potential customers, which could reduce our revenues.
The value of our CRE marketplace services to our customers depends on our ability to increase the number of property listings provided and searches conducted.
The success of our CRE marketplace services depends substantially on the number of property listings submitted by brokers, agents, property owners and, in the
case of apartment rentals, property managers. This is because an increase in the number of listings increases the utility of the online service and of its associated
search,  listing  and  marketing  services.  If  agents  marketing  large  numbers  of  property  listings,  such  as  large  brokers  in  key  real  estate  markets,  choose  not  to
continue  their  listings  with  us,  or  choose  to  list  them  with  a  competitor,  our  CRE  marketplace  services  could  be  less  attractive  to  other  real  estate  industry
transaction participants, resulting in reduced revenue. Similarly, the value and utility of our other marketplaces, including the BizBuySell.com network of business
for-sale websites, are also dependent on attracting and retaining listings.

If we are unable to convince commercial real estate professionals that our CRE marketplace services are superior to traditional methods of listing, searching
and marketing commercial real estate, they could choose not to use those services, which could reduce our revenues or increase our expenses. The primary source
of  new  customers  for  our  CRE  marketplace  services  is  participants  in  the  commercial  real  estate  community.  Many  commercial  real  estate  professionals  are
accustomed to listing, searching and marketing  real estate in traditional  and off-line ways, such as by distributing  print brochures, sharing written lists, placing
signs on properties, word-of-mouth and newspaper advertisements. Commercial real estate and investment professionals may prefer to continue to use traditional
methods or may be slow to adopt and accept our online products and services. If we are not able to persuade commercial real estate participants of the efficacy of
our  online  products  and  services,  they  may  choose  not  to  use  our  CRE  marketplace  services,  which  could  negatively  impact  our  business.  Similarly,  if  we  are
unable  to  convince  the  business  and  investment  community  to  utilize  our  online  business  for-sale  marketplaces  rather  than  traditional  methods  of  listing  and
marketing businesses for-sale, our revenues could be negatively affected.

25

If  we  are  unable  to  increase  our  revenues  or  our  operating  costs  are  higher  than  expected,  our  profitability  may  decline  and  our  operating  results  may
fluctuate significantly. We may not be able to accurately forecast our revenues or future revenue growth rate. Many of our expenses, particularly personnel costs
and  occupancy  costs,  are  relatively  fixed.  As  a  result,  we  may  not  be  able  to  adjust  spending  quickly  enough  to  offset  any  unexpected  increase  in  expenses  or
revenue  shortfall.  We  may  experience  higher  than  expected  operating  costs,  including  increased  personnel  costs,  occupancy  costs,  selling  and  marketing  costs,
investments  in  geographic  expansion,  acquisition  costs,  communications  costs,  travel  costs,  software  development  costs,  professional  fees  and  other  costs.  If
operating costs exceed our expectations and cannot be adjusted accordingly, our profitability may be reduced and our results of operations and financial position
will be adversely affected. Additionally, we may not be able to sustain our revenue growth rates, and our percentage revenue growth rates may decline. Our ability
to increase our revenues and operating profit will depend on increased demand for our services. Our sales are affected by, among other things, general economic
and commercial real estate conditions. Reduced demand, whether due to changes in customer preference, a weakening of the U.S. or global economy, competition
or other reasons, may result in decreased revenues and growth, adversely affecting our operating results.

Our current or future geographic expansion plans may not result in increased revenues, which may negatively impact our business, results of operations and
financial position. Expanding into new markets and investing resources towards increasing the depth of our coverage within existing markets impose additional
burdens on our research, systems development, sales, marketing and general managerial resources. If we are unable to manage our expansion efforts effectively, if
our  expansion  efforts  take  longer  than  planned  or  if  our  costs  for  these  efforts  exceed  our  expectations,  our  financial  position  could  be  adversely  affected.  In
addition, if we incur significant costs to improve data quality within existing markets, or are not successful in marketing and selling our services in these markets
or  in  new  markets,  our  expansion  may  have  a  material  adverse  effect  on  our  financial  position  by  increasing  our  expenses  without  increasing  our  revenues,
adversely affecting our profitability.

International operations expose us to additional business risks, which may reduce our profitability. Our international operations and expansion subject us to
additional  business  risks,  including:  currency  exchange  rate  fluctuations;  adapting  to  the  differing  business  practices  and  laws  in  foreign  countries;  including
differing  laws  regarding  privacy  and  data  protection;  difficulties  in  managing  foreign  operations;  limited  protection  for  intellectual  property  rights  in  some
countries; difficulty in collecting accounts receivable and longer collection periods; costs of enforcing contractual obligations; impact of recessions in economies
outside the U.S.; and potentially adverse tax consequences. In addition, international expansion imposes additional burdens on our executive and administrative
personnel,  systems  development,  research  and  sales  departments,  and  general  managerial  resources.  If  we  are  not  able  to  manage  our  international  operations
successfully, we may incur higher expenses and our profitability may be reduced. Finally, the investment required for additional international expansion sometimes
exceeds the profit generated from such expansion, which reduces our profitability and may adversely affect our financial position.

Fluctuating  foreign  currencies  may  negatively  impact  our  business,  results  of  operations  and  financial  position.  Due  to  our  international  acquisitions  and
expansion  efforts,  a  portion  of  our  business  is  denominated  in  foreign  currencies.  As  a  result,  fluctuations  in  foreign  currencies  may  have  an  impact  on  our
business, results of operations and financial position. Foreign currency exchange rates have fluctuated and may continue to fluctuate. Significant foreign currency
exchange rate fluctuations may negatively impact our international revenue, which in turn affects our consolidated revenue. Currencies may be affected by internal
factors, general economic conditions and external developments in other countries, all of which can have an adverse impact on a country’s currency. Currently, we
are not party to any hedging transactions  intended to reduce our exposure to exchange  rate fluctuations.  We may seek to enter into hedging transactions in the
future, but we may be unable to enter into these transactions successfully, on acceptable terms or at all. We cannot predict whether we will incur foreign exchange
losses in the future. Further, significant foreign exchange fluctuations resulting in a decline in the respective local currency may decrease the value of our foreign
assets,  as  well  as  decrease  our  revenues  and  earnings  from  our  foreign  subsidiaries,  which  would  reduce  our  profitability  and  adversely  affect  our  financial
position.

The economic effects of “Brexit” may affect relationships with existing and future customers and could have an adverse impact on our business and operating
results. On June  23,  2016, the  U.K.  held  a  referendum  in  which  British  citizens  approved  an  exit  from  the  European  Union (“E.U.”),  commonly  referred  to  as
“Brexit.” On January 31, 2020, the U.K. officially withdrew from the E.U, beginning a transition period of negotiations between the British government and the
E.U. and other governments. Uncertainty regarding the U.K.’s withdrawal from the E.U. could cause political and economic uncertainty in the U.K. and the rest of
Europe, which could harm our business and financial results. In particular, Brexit could result in significant volatility in global equity markets, currency exchange
rates and other asset prices, including those related to real property. The impact to us from Brexit will depend, in part, on the outcome of tariff, trade, regulatory
and other negotiations, the results of which are currently uncertain. This impact may affect not only our U.K. operations but operations in other parts of the E.U.
Any transitional or permanent agreements resulting from such negotiations could potentially disrupt the markets we serve and the tax jurisdictions in which we
operate.

26

A potential devaluation of the local currencies of our international customers relative to the U.S. dollar may impair the purchasing power of our international
customers and could cause international customers to decrease or cancel orders, or terminate or fail to renew subscriptions for our services. We translate sales
and  other  results  denominated  in  foreign  currency  into  U.S.  dollars  for  our  financial  statements.  During  periods  of  a  strengthening  U.S.  dollar,  our  reported
international sales and earnings could be reduced because foreign currencies may translate into fewer U.S. dollars. Resulting asset price volatility that could follow
the withdrawal of the U.K. from the E.U. may create global economic uncertainty, which may cause our customers to closely monitor their costs and reduce their
spending budgets on our products and services. In addition, Brexit is likely to lead to legal uncertainty and potentially divergent national laws and regulations as
the U.K determines which E.U. laws to replace or replicate, and those laws and regulations may be cumbersome, difficult or costly in terms of compliance. Further,
Brexit  may  lead  other  E.U.  member  countries  to  consider  referendums  regarding  their  E.U.  membership.  Any  of  these  effects  of  Brexit,  among  others,  could
adversely affect our business, financial condition, operating results and cash flows.

Changes in laws, regulations or fiscal and tax policies or the manner of their interpretation or enforcement could adversely impact our financial performance.
New laws or regulations, or changes in existing laws or regulations, or the manner of their interpretation or enforcement, could increase our cost of doing business.
For example, in December 2017, the United States enacted The Tax Cuts and Jobs Act (the "Tax Act"), and various provisions of the new law may adversely affect
us. Certain aspects of Tax Reform are unclear and may not be clarified for some time. During 2018, the Department of the Treasury issued certain guidance in the
form of notices and proposed regulations with respect to several provisions of the new legislation. We expect that additional regulations or other guidance may be
issued with respect to the Tax Act in subsequent years. We continue to examine the impact this tax reform legislation may have on our business. In addition, if
federal,  state,  local  or  foreign  tax  authorities  change  applicable  tax  laws  or  issue  new  guidance,  including  in  response  to  the  Tax  Act,  our  overall  taxes  could
increase, and our business, financial condition or results of operations may be adversely impacted.

Our indebtedness could adversely affect us, including by decreasing our business flexibility and increasing our costs. The 2017 Credit Agreement provides for
a $750 million revolving credit facility with a term of five years from a syndicate of financial institutions as lenders and issuing banks. The 2017 Credit Agreement
contains customary restrictive covenants imposing operating and financial restrictions on us, including restrictions that may limit our ability to engage in acts that
we believe may be in our long-term best interests. These covenants restrict our ability and the ability of our subsidiaries to, among other things, (i) incur additional
indebtedness,  (ii)  create,  incur,  assume  or  permit  to  exist  any  liens,  (iii)  enter  into  mergers,  consolidations  or  similar  transactions,  (iv)  make  investments  and
acquisitions,  (v)  make  certain  dispositions  of  assets,  (vi)  make  dividends,  distributions  and  prepayments  of  certain  indebtedness  and  (vii)  enter  into  certain
transactions with affiliates.

The operating restrictions and financial covenants in the 2017 Credit Agreement and any future financing agreements may limit our ability to finance future
operations or capital needs, to engage in other business activities or to respond to changes in market conditions. Our ability to comply with any financial covenants
could be affected materially by events beyond our control, and we may be unable to satisfy any such requirements. If we fail to comply with these covenants, we
may need to seek waivers or amendments of such covenants, seek alternative or additional sources of financing or reduce our expenditures. We may be unable to
obtain such waivers, amendments or alternative or additional financing on a timely basis or at all, or on favorable terms.

We  are  required  to  make  periodic  principal  and  interest  payments  pursuant  to  the  terms  of  the  2017  Credit  Agreement.  If  an  event  of  default  occurs,  the
interest rate on any overdue amounts will increase and the lenders under the 2017 Credit Agreement may declare all outstanding borrowings, together with accrued
interest and other fees, to be immediately due and payable and may exercise remedies in respect of the collateral. We may not be able to repay all amounts due
under the 2017 Credit Agreement in the event these amounts are declared due upon an event of default.

Negative  conditions  in  the  global  credit  markets  may  affect  the  liquidity  of  a  portion  of  our  long-term  investments.   Currently,  our  long-term  investments
include mostly AAA-rated auction rate securities (“ARS”), which are primarily student loan securities supported by guarantees from the Federal Family Education
Loan Program (“FFELP”) of the U.S. Department of Education. Continuing negative conditions in the global credit markets have prevented some investors from
liquidating  their  holdings  of  auction  rate  securities  because  the  amount  of  securities  submitted  for-sale  has  exceeded  the  amount  of  purchase  orders  for  such
securities. As of December 31, 2019, we held $11 million par value of ARS, all of which failed to settle at auctions. When an auction fails for ARS in which we
have invested, we may be unable to liquidate some or all of these securities at par. In the event we need or desire to immediately access these funds, we will not be
able to do so until a future auction on these investments is successful, a buyer is found outside the auction process or an alternative action is determined. If a buyer
is found but is unwilling to purchase the investments at par, we may incur a loss, which would reduce our profitability and adversely affect our financial position.

Our operating results and revenues are subject to fluctuations and our quarterly financial results may be subject to market cyclicality, each of which could

cause our stock price to be negatively affected. The commercial real estate market may be influenced

27

by general economic conditions, economic cycles, annual seasonality factors and many other factors, which in turn may impact our financial results. The market is
large and fragmented. The different sectors of the industry, such as office, industrial, retail, multifamily, and others, are influenced differently by different factors,
and  have  historically  moved  through  economic  cycles  with  different  timing.  As  such,  it  is  difficult  to  estimate  the  potential  impact  of  economic  cycles  and
conditions  or  seasonality  from  year-to-year  on  our  overall  operating  results.  We  generally  see  higher  sales  of  Apartments.com  listing  services  during  the  peak
summer rental season and higher CoStar Suite sales towards the end of the year, however sales fluctuate from year-to-year. In addition, we generally incur greater
marketing expenses during the second quarter, which coincides with the peak season for apartment rentals. The timing of widely observed holidays and vacation
periods,  particularly  slowdowns  during  the  end-of-year  holiday  period,  and  availability  of  real  estate  agents  and  related  service  providers  during  these  periods,
could significantly affect our quarterly operating results during that period. If we are unable to adequately respond to economic, seasonal or cyclical conditions, our
revenues,  expenses  and  operating  results  may  fluctuate  from  quarter  to  quarter.  Our  operating  results,  revenues  and  expenses  may  fluctuate  for  many  reasons,
including those described below and elsewhere in this Annual Report on Form 10-K:

Rates of subscriber adoption and retention;
Timing of our sales conference or significant marketing events;
A slow-down during the end-of-year holiday period;
Changes in our pricing strategy and timing of changes;
The timing and success of new service introductions and enhancements;
The shift of focus from, or phase out of services that overlap or are redundant with other services we offer;
The amount and timing of our operating expenses and capital expenditures;
Our ability to control expenses;
The amount and timing of non-cash stock-based charges;
Costs related to acquisitions of businesses or technologies or impairment charges associated with such investments and acquisitions;
Competition;
Changes or consolidation in the real estate industry;
Our investments in geographic expansion and to increase coverage in existing markets;
Interest rate fluctuations;
Successful execution of our expansion and integration plans;
The development of our sales force;
Foreign currency and exchange rate fluctuations;
Inflation; and
Changes in client budgets.

These fluctuations could negatively affect our results of operations during the period in question and/or future periods or cause our stock price to decline. In
addition, changes in accounting policies or practices may affect our level of net income. Fluctuations in our financial results, revenues and expenses may cause the
market price of our common stock to decline.

The consent order approved by the Federal Trade Commission in connection with the LoopNet merger imposes conditions that could have an adverse effect
on us and our business, and failure to comply with the terms of the consent order may result in adverse consequences for the combined company. On April 26,
2012, the FTC accepted the consent order in connection with the LoopNet merger that was previously agreed to among the FTC staff, CoStar, and LoopNet on
April 17, 2012. The consent order was subject to a 30-day public comment period, and on August 29, 2012, the FTC issued its final acceptance of the consent
order.

The consent order, which is publicly available on the FTC's website at http://www.ftc.gov/,  requires us to maintain  certain business practices that the FTC
believes are pro-competitive. For example, the consent order requires us to license our products to customers who have bought its competitors' products on a non-
discriminatory  basis. In addition,  we are required  to provide  the FTC with advance  written  notification  of certain  acquisitions  for which notification  would not
otherwise  be  required  under  the  Hart-Scott-Rodino  Premerger  Notification  Act.  This  provision  of  the  consent  order  requiring  CoStar  to  provide  the  FTC  with
advance  written  notification  of  certain  acquisitions  could  prevent  us  from  closing  certain  acquisitions  or  add  significant  time  and  cost  to  these  potential
acquisitions,  ultimately  making an acquisition  prohibitive  or preventing  us from realizing  anticipated  benefits  of an acquisition.  In the event  that we fail  or are
unable to comply with the terms of the consent order, we could be subject to an enforcement  proceeding that could result in substantial fines and/or injunctive
relief.

Changes  in  accounting  and  reporting  policies  or  practices  may  affect  our  financial  results  or  presentation  of  results,  which  may  affect  our  stock  price.
Changes in accounting and reporting policies or practices could reduce our net income, which reductions may be independent of changes in our operations. These
reductions in reported net income could cause our stock price to decline.

Properties

Our headquarters is located at 1331 L Street, NW, in downtown Washington, DC, where we occupy approximately 159,331 square feet of office space, with a

lease that expires May 31, 2025 (with two 5-year renewal options). Our headquarters is used primarily by our North America operating segment. Our principal
facility in the U.K. is located in London, where we occupy 23,064 square feet of office space. Our lease for this facility has a term ending August 31, 2025. This
facility is used by our International operating segment.

We also operate our research functions out of leased office spaces in Richmond, Virginia; San Diego, California; and Atlanta, Georgia. Additionally, we lease
office space in a variety of other metropolitan areas. These locations include, among others, the following: Hendersonville, Tennessee; Irvine, California; Boston,
Massachusetts; San Francisco, California; Ontario, California; and Los Angeles, California. 

We believe these facilities are suitable and appropriately support our business needs.

Legal Proceedings

Currently,  and  from  time  to  time,  we  are  involved  in  litigation  incidental  to  the  conduct  of  our  business.  We  are  not  currently  a  party  to  any  lawsuit  or
proceeding that, in the opinion of our management based on consultations with legal counsel, is likely to have a material adverse effect on our financial position or

Management’s Discussion and Analysis of Financial Condition and Results of Operations

The  following  Management’s  Discussion  and  Analysis  of  Financial  Condition  and  Results  of  Operations  contains  “forward-looking  statements,”  including
statements about our beliefs and expectations. There are many risks and uncertainties that could cause actual results to differ materially from those discussed in the
forward-looking statements. Potential factors that could cause actual results to differ materially from those discussed in any forward-looking statements include,
but  are  not  limited  to,  those  stated  above  in  Item  1A.  under  the  headings  “Risk  Factors  -  Cautionary  Statement  Concerning  Forward-Looking  Statements”  and
“Risk Factors,” as well as those described from time to time in our filings with the Securities and Exchange Commission.

All  forward-looking  statements  are  based  on  information  available  to  us  on  the  date  of  this  filing  and  we  assume  no obligation  to  update  such  statements,
whether as a result of new information, future events or otherwise. The following discussion should be read in conjunction with our Quarterly Reports on Form 10-
Q,  Current  Reports  on  Form  8-K  and  other  filings  with  the  Securities  and  Exchange  Commission  and  the  consolidated  financial  statements  and  related  notes
included in this Annual Report on Form 10-K.

Overview

Our principal information, analytics and online marketplace services are described in the following paragraphs by type of service:

Information and Analytics

CoStar Suite®. Our subscription-based information services consist primarily of CoStar Suite services. CoStar Suite is sold as a platform of service offerings
consisting of CoStar Property®, CoStar COMPS®, CoStar Market Analytics, CoStar Tenant®, CoStar Lease Comps and CoStar Public Record through our mobile
applications. Our integrated suite of online service offerings includes information about space available for-lease, comparable sales information, information about
properties  for-sale,  tenant  information,  Internet  marketing  services,  analytical  capabilities,  information  for  clients'  websites,  information  about  industry
professionals  and  their  business  relationships,  and  industry  news.  Our  sales  force  is  responsible  for  selling  multiple  product  lines,  including  CoStar  Suite  and
LoopNet.  During 2020, we plan to shift the focus of our sales force to sales of LoopNet Signature Ads.  As a result, we anticipate CoStar Suite revenue growth
will moderate during the year.

Information services. We provide real estate and lease management solutions, including lease administration and abstraction services, through our CoStar Real
Estate  Manager®  service  offerings,  as  well  as  portfolio  and  debt  analysis,  management  and  reporting  capabilities  through  our  CoStar  Investment  Analysis  and
CoStar Risk Analytics® service offerings. We provide information services internationally, through our Grecam, Belbex and Thomas Daily businesses in France,
Spain  and  Germany,  respectively.  Sales  of  CoStar  Real  Estate  Manager  represent  a  significant  portion  of  our  information  services  revenue.  CoStar  Real  Estate
Manager's revenue growth rates increased significantly in 2018 as new clients adopted, and existing clients expanded their use of, CoStar Real Estate Manager to
manage compliance with new lease accounting and reporting requirements which became effective for public companies for financial reporting periods beginning
after December 15, 2018. As a result, we expect the growth rate for CoStar Real Estate Manager to normalize as the initial surge of the demand has eased. On
October 22, 2019, we acquired STR and we now also provide STR’s complementary benchmarking and analytics services to the hospitality industry. We expect
that the acquisition of STR and the combination of STR's and CoStar's offerings will allow us to create valuable new and improved tools for industry participants.
See Note 4 to the accompanying Notes to the Consolidated Financial Statements included in Part IV of this Annual Report on Form 10-K for further discussion of
the acquisition of STR.

Online Marketplaces

Multifamily.  Apartments.comTM is  part  of  our  network  of  apartment  marketing  sites,  which  primarily  includes  ApartmentFinder®,  ForRent.com®,
ApartmentHomeLiving.comTM,  Apartamentos.comTM,  Westside  Rentals  and  Off  Campus  Partners,  LLC  ("OCP").  Our  apartment  marketing  network  of
subscription-based  services  offers  renters  a  searchable  database  of  apartment  listings  and  provides  professional  property  management  companies  and  landlords
with an advertising destination. On February 21, 2018, we completed the acquisition of ForRent, a division of Dominion Enterprises, including the ForRent.com,
AFTER55.com, CorporateHousing.com and ForRentUniversity.com apartment marketing sites. On November 8, 2018, we acquired Cozy Services, Ltd. ("Cozy"),
a  provider  of  online  rental  solutions  that  provides  a  broad  spectrum  of  services  to  both  landlords  and  tenants,  including  property  listings,  rent  estimates,  rental
applications, tenant screening, online rent payments and expense tracking. On June 12, 2019, we acquired OCP, a provider of student housing marketplace content
and technology to U.S. universities. We expect the multifamily annual revenue growth rate to remain consistent with 2019 as we have fully integrated our ForRent
and Cozy acquisitions into our service offerings. We continue to work on integrating the OCP acquisition and the

33

 
services they offer into our Apartments.com network. See Note 4 to the accompanying Notes to the Consolidated Financial Statements included in Part IV of this
Annual Report on Form 10-K for further discussion of these acquisitions.

Commercial  property  and  land.  Our  LoopNet.com  network  of  commercial  real  estate  websites  offer  subscription-based,  online  marketplace  services  that
enable  commercial  property  owners,  landlords  and  real  estate  agents  working  on  their  behalf  to  list  properties  for-sale  or  for-lease  and  to  submit  detailed
information about property listings. Commercial real estate agents, buyers and tenants use the LoopNet.com network of online marketplace services to search for
available  property listings  that meet  their  criteria.  As part  of our rebuild  and launch  of the  LoopNet Signature  Ads product, we rolled  out new packages in the
fourth quarter of 2019. As a result, the growth rate increased in the fourth quarter of 2019, and LoopNet is expected to continue to grow in the subsequent periods.
In  addition,  on  October  12,  2018,  we  acquired  all  of  the  issued  share  capital  of  Realla  Ltd.  ("Realla"),  the  operator  of  a  commercial  property  listings  and  data
management  platform  in  the  U.K.,  including  a  free-to-list  search  engine  for  commercial  property  listings.  See  Note  4  to  the  accompanying  Notes  to  the
Consolidated Financial Statements included in Part IV of this Annual Report on Form 10-K for further discussion of the acquisition of Realla. Our BizBuySell.com
network,  which  includes  BizQuest®  and  FindaFranchise,  provides  online  marketplaces  for  businesses  for-sale.  Our  Land.com  network  of  sites,  which  provides
online marketplaces for rural lands for-sale, includes LandsofAmerica, LandAndFarm and LandWatch®.

For the years ended December 31, 2019, 2018 and 2017 our annualized net new bookings of subscription-based services on all contracts were approximately
$210 million, $169 million and $148 million, respectively, calculated based on the annualized amount of change in our sales resulting from all new subscription-
based  contracts  or  upsales  on  all  existing  subscription-based  contracts,  less  write  downs  and  cancellations,  for  the  period  reported.  We  recognize  subscription
revenues on a straight-line basis over the life of the contract. Net bookings is considered a key indicator of future subscription revenue growth and is also used as a
metric of salesforce productivity by management and investors.

For the years ended December 31, 2019, 2018 and  2017, our contract renewal rate for existing CoStar subscription-based services on annual contracts was
approximately 90%, 90% and 91% respectively, and, therefore, our cancellation rate for those services was approximately  10%, 10%, and 9%, respectively. Our
contract renewal rate is a quantitative measurement that is typically closely correlated with our revenue results. As a result, management also believes that the rate
may  be  a  reliable  indicator  of  short-term  and  long-term  performance.  Our  trailing  twelve-month  contract  renewal  rate  may  decline  if,  among  other  reasons,
negative  economic  conditions  lead  to  greater  business  failures  and/or  consolidations  among  our  clients,  reductions  in  customer  spending,  or  decreases  in  our
customer base.

Development, Investments and Expansion

We are committed to supporting, improving and enhancing our information, analytics and online marketplace solutions, including expanding and improving
our offerings for property owners, property managers and renters. We expect to continue our software development efforts to improve existing services, introduce
new services, integrate and cross-sell services, and expand and develop supporting technologies for our research, sales and marketing organizations.

Our key priorities for 2020 include:

•

•

Continue to develop, improve and market our recently launched Apartments.com service offerings that focus on the digital rental experience and enable
renters to apply for-leases, and for landlords to run tenant credit and background checks and make rent payments, all online through a single platform. We
plan to aggressively market our multifamily listing services in an effort to provide more value to advertisers and, in turn, to attract advertisers. As such,
we plan to increase our investment in Apartments.com marketing in 2020 by approximately $100 million, which may reduce our margins and profitability
while  we  invest  in  future  growth.  The  increased  investment  is  focused  on  search  engine  marketing  and  enhanced  brand  awareness.  We  also  plan  to
continue to invest in our multifamily business by increasing the size of our sales force with a focus on increasing sales to midsize and smaller apartment
communities.

Obtaining  necessary  bankruptcy  court  and  regulatory  approvals  to  close  the  pending  acquisition  of  RentPath  and  integrating  RentPath  with  the
Apartments.com network post-closing. On February 11, 2020, a wholly owned subsidiary of the Company entered into an agreement to acquire for $588
million in cash all of the equity interests of RentPath Holdings, Inc., as reorganized following an internal restructuring pursuant to and under the joint

Continue to invest in the LoopNet marketplace by enhancing the content on the site (including high-quality imagery), seeking targeted advertisements,
providing premium listing services (such as LoopNet Signature Ads) that increase a property listing’s exposure, and adding more content for premium
listings  to  better  meet  the  needs  of  a  broader  cross  section  of  the  commercial  real  estate  industry.  Additionally,  we  initiated  training  and  incentive
programs for our sales team to increase sales of LoopNet Signature Ads, with a focus on property owners.

Integrating recently completed acquisitions, including STR, with CoStar’s business operations. We plan to consolidate STR data and services with CoStar
Suite  to  create  an  integrated  platform.  We  plan  to  drive  international  expansion,  in  part,  through  STR's  global  operations  and  to  apply  STR's
benchmarking expertise to other commercial real estate segments served by CoStar.

Continue to invest in CoStar Suite, including capabilities that allow us to broaden the reach of CoStar Suite in Europe by offering multiple languages and
currencies on the platform. We plan to enhance CoStar Suite by making additional investments in analytical capabilities focused on owners and lenders of
commercial real estate. In addition, we plan to invest in integrating the technology and infrastructure from other existing service offerings into the CoStar
Suite  platform,  including  CoStar  Real  Estate  Manager,  in  order  to  leverage  data  and  technology  across  our  platforms  and  provide  customers  with
additional functionality.

We intend to continue to assess the need for additional investments in our business, in addition to the investments discussed above, in order to develop and
distribute  new  services  and  functionality  within  our  current  platform  or  expand  the  reach  of,  or  otherwise  improve,  our  current  service  offerings.  Any  future
product  development  or  expansion  of  services,  combination  and  coordination  of  services  or  elimination  of  services  or  corporate  expansion,  development  or
restructuring efforts could reduce our profitability and increase our capital expenditures. Any new investments, changes to our service offerings or other unforeseen
events  could  cause  us  to  experience  reduced  revenues  or  generate  losses  and  negative  cash  flow  from  operations  in  the  future.  Any  development  efforts  must
comply with our credit facility, which contains restrictive covenants that restrict our operations and use of our cash flow and may prevent us from taking certain
actions that we believe could increase our profitability or otherwise enhance our business.

For further discussion of our Company, strategy and products, see our business overview set forth in "Item 1. Business" in this Annual Report on Form 10-K.

Non-GAAP Financial Measures

We prepare and publicly release quarterly unaudited financial statements prepared in accordance with generally accepted accounting principles (“GAAP”). We
also  disclose  and  discuss  certain  non-GAAP  financial  measures  in  our  public  releases,  investor  conference  calls  and  filings  with  the  Securities  and  Exchange
Commission. The non-GAAP financial measures that we may disclose include net income before interest and other income (expense), loss on debt extinguishment,
income taxes, depreciation and amortization (“EBITDA”), adjusted EBITDA, adjusted EBITDA margin, non-GAAP net income and non-GAAP net income per
diluted share. EBITDA is our net income before interest and other income (expense), loss on debt extinguishment, income taxes, depreciation and amortization.
We typically disclose EBITDA on a consolidated and an operating segment basis in our earnings releases, investor conference calls and filings with the Securities
and Exchange Commission. Adjusted EBITDA is different from EBITDA because we further adjust EBITDA for stock-based compensation expense, acquisition-
and integration-related costs for pending and completed acquisitions, restructuring costs and settlements and impairments incurred outside our ordinary course of
business. Non-GAAP net income is determined by adjusting our net income for stock-based compensation expense, acquisition- and integration-related costs for
pending  and  completed  acquisitions,  restructuring  costs,  settlement  and  impairment  costs  incurred  outside  our  ordinary  course  of  business  and  loss  on  debt
extinguishment, as well as amortization of acquired intangible assets and other related costs, and then subtracting an assumed provision for income taxes. We may
disclose adjusted EBITDA, adjusted EBITDA margin, non-GAAP net income and non-GAAP net income per diluted share on a consolidated basis in our earnings
releases,  investor  conference  calls  and  filings  with  the  Securities  and  Exchange  Commission.  The  non-GAAP  financial  measures  that  we  use  may  not  be
comparable to similarly titled measures reported by other companies. Also, in the future, we may disclose different non-GAAP financial measures in order to help
our investors meaningfully evaluate and compare our results of operations to our previously reported results of operations or to those of other companies in our
industry.

We view EBITDA, adjusted EBITDA, non-GAAP net income and non-GAAP net income per diluted share as operating performance measures and as such we
believe that the most directly comparable GAAP financial measure to EBITDA, adjusted EBITDA and non-GAAP net income is net income. We believe the most
directly comparable GAAP financial measures to non-GAAP net income per diluted share and adjusted EBITDA margin are net income per diluted share and net
income divided by revenue, respectively. In calculating EBITDA, adjusted EBITDA, adjusted EBITDA margin, non-GAAP net income and non-

35

GAAP net income per diluted share, we exclude from net income the financial items that we believe should be separately identified to provide additional analysis
of  the  financial  components  of  the  day-to-day  operation  of  our  business.  We  have  outlined  below  the  type  and  scope  of  these  exclusions  and  the  material
limitations on the use of these non-GAAP financial measures as a result of these exclusions. EBITDA, adjusted EBITDA, adjusted EBITDA margin, non-GAAP
net income and non-GAAP net income per diluted share are not measurements of financial performance under GAAP and should not be considered as a measure of
liquidity,  as  an  alternative  to  net  income  or  as  an  indicator  of  any  other  measure  of  performance  derived  in  accordance  with  GAAP.  Investors  and  potential
investors  in  our  securities  should  not  rely  on  EBITDA,  adjusted  EBITDA,  adjusted  EBITDA  margin,  non-GAAP  net  income  and  non-GAAP  net  income  per
diluted share as a substitute for any GAAP financial measure, including net income and net income per diluted share. In addition, we urge investors and potential
investors in our securities to carefully review the GAAP financial information included as part of our Annual Reports on Form 10-K and Quarterly Reports on
Form 10-Q that are filed with the Securities and Exchange Commission, as well as our quarterly earnings releases, and compare the GAAP financial information
with our EBITDA, adjusted EBITDA, adjusted EBITDA margin, non-GAAP net income and non-GAAP net income per diluted share.

EBITDA, adjusted EBITDA, adjusted EBITDA margin, non-GAAP net income and non-GAAP net income per diluted share may be used by management to
internally measure our operating and management performance and may be used by investors as supplemental financial measures to evaluate the performance of
our business. We believe that these non-GAAP measures, when viewed with our GAAP results and accompanying reconciliations, provide additional information
to investors that is useful to understand the factors and trends affecting our business. We have spent more than 30 years building our database of commercial real
estate information and expanding our markets and services partially through acquisitions of complementary businesses. Due to the expansion of our information,
analytics and online marketplace services, which has included acquisitions, our net income has included significant charges for amortization of acquired intangible
assets, depreciation and other amortization, acquisition- and integration-related costs for pending and completed acquisitions, restructuring costs, and loss on debt
extinguishment.  Adjusted  EBITDA,  adjusted  EBITDA  margin,  non-GAAP  net  income  and  non-GAAP  net  income  per  diluted  share  exclude  these  charges  and
provide meaningful information about the operating performance of our business, apart from charges for amortization of acquired intangible assets, depreciation
and  other  amortization,  acquisition-  and  integration-related  costs  for  pending  and  completed  acquisitions,  restructuring  costs;  settlement  and  impairment  costs
incurred  outside our ordinary course of business. We believe  the disclosure  of non-GAAP measures  can help investors meaningfully evaluate  and compare  our
performance  from  quarter  to  quarter  and  from  year  to  year.  We  also  believe  the  non-GAAP  measures  we  disclose  are  measures  of  our  ongoing  operating
performance  because  the  isolation  of  non-cash  charges,  such  as  amortization  and  depreciation,  and  other  items,  such  as  interest,  income  taxes,  stock-based
compensation  expenses,  acquisition-  and  integration-related  costs  for  pending  and  completed  acquisitions,  restructuring  costs;  loss  on  debt  extinguishment  and
settlement and impairment costs incurred outside our ordinary course of business, provides additional information about our cost structure, and, over time, helps
track our operating progress. In addition, investors, securities analysts and others have regularly relied on EBITDA and may rely on adjusted EBITDA, adjusted
EBITDA  margin,  non-GAAP  net  income  or  non-GAAP  net  income  per  diluted  share  to  provide  a  financial  measure  by  which  to  compare  our  operating
performance against that of other companies in our industry.

Set forth below are descriptions of financial items that have been excluded from net income to calculate EBITDA and the material limitations associated with

using this non-GAAP financial measure as compared to net income:

•

•

•

•

Amortization of acquired intangible assets in cost of revenues may be useful for investors to consider because it represents the diminishing value of any
acquired trade names and other intangible assets and the use of our acquired technology, which is one of the sources of information for our database of
commercial real estate information. We do not believe these charges necessarily reflect the current and ongoing cash charges related to our operating cost
structure.

Amortization of acquired intangible assets in operating expenses may be useful for investors to consider because it represents the estimated attrition of our
acquired customer base. We do not believe these charges necessarily reflect the current and ongoing cash charges related to our operating cost structure.

Depreciation  and  other  amortization  may  be  useful  for  investors  to  consider  because  they  generally  represent  the  wear  and  tear  on  our  property  and
equipment used in our operations. We do not believe these charges necessarily reflect the current and ongoing cash charges related to our operating cost
structure.

The amount of interest and other income and expense we generate and incur may be useful for investors to consider and may result in current cash inflows
and  outflows.  However,  we  do  not  consider  the  amount  of  interest  and  other  income  and  expense  to  be  a  representative  component  of  the  day-to-day
operating performance of our business.

36

•

•

Income tax expense may be useful for investors to consider because it generally represents the taxes which may be payable for the period and the change
in deferred income taxes during the period and may reduce the amount of funds otherwise available for use in our business. However, we do not consider
the amount of income tax expense to be a representative component of the day-to-day operating performance of our business.

The  amount  of  loss  on  our  debt  extinguishment  may  be  useful  for  investors  to  consider  because  it  generally  represents  losses  from  the  early
extinguishment of debt. However, we do not consider the amount of the loss on debt extinguishment to be a representative component of the day-to-day
operating performance of our business.

Set  forth  below  are  descriptions  of  additional  financial  items  that  have  been  excluded  from  EBITDA  to  calculate  adjusted  EBITDA  and  the  material

limitations associated with using this non-GAAP financial measure as compared to net income:

•

•

•

•

Stock-based  compensation  expense  may  be  useful  for  investors  to  consider  because  it  represents  a  portion  of  the  compensation  of  our  employees  and
executives. Determining the fair value of the stock-based instruments involves a high degree of judgment and estimation and the expenses recorded may
bear little resemblance to the actual value realized upon the future exercise or termination of the related stock-based awards. Therefore, we believe it is
useful to exclude stock-based compensation in order to better understand the long-term performance of our core business.

The amount of acquisition- and integration- related costs for pending and completed acquisitions incurred may be useful for investors to consider because
such costs generally represent professional service fees and direct expenses related to acquisitions. Because we do not acquire businesses on a predictable
cycle,  we  do  not  consider  the  amount  of  acquisition-  and  integration-  related  costs  for  pending  and  completed  acquisitions  to  be  a  representative
component of the day-to-day operating performance of our business.

The amount of settlement and impairment costs incurred outside of our ordinary course of business may be useful for investors to consider because they
generally represent gains or losses from the settlement of litigation matters or impairments on acquired intangible assets. We do not believe these charges
necessarily reflect the current and ongoing cash charges related to our operating cost structure.

The amount of restructuring costs incurred may be useful for investors to consider because they generally represent costs incurred in connection with a
change  in  a  contract  or  a  change  in  the  makeup  of  our  properties  or  personnel.  We  do  not  consider  the  amount  of  restructuring  related  costs  to  be  a
representative component of the day-to-day operating performance of our business.

The  financial  items  that  have  been  excluded  from  our  net  income  to  calculate  non-GAAP  net  income  and  non-GAAP  net  income  per  diluted  share  are
amortization of acquired intangible assets and other related costs, stock-based compensation, acquisition- and integration- related costs for pending and completed
acquisitions, restructuring and related costs and settlement and impairment costs incurred outside our ordinary course of business. These items are discussed above
with respect to the calculation of adjusted EBITDA together with the material limitations associated with using this non-GAAP financial measure as compared to
net income. In addition to these exclusions from net income, we subtract an assumed provision for income taxes to calculate non-GAAP net income. In 2019 and
2018, we assumed a 25% tax rate which approximated our historical long-term statutory corporate tax rate, excluding the impact of discrete items.

Adjusted EBITDA margin represents adjusted EBITDA divided by revenues for the period.

Non-GAAP net income per diluted share is a non-GAAP financial measure that represents non-GAAP net income divided by the number of diluted shares

outstanding for the period used in the calculation of GAAP net income per diluted share.

Management compensates for the above-described limitations of using non-GAAP measures by using a non-GAAP measure only to supplement our GAAP

results and to provide additional information that is useful to understand the factors and trends affecting our business.

Revenues.  Revenues  increased to  $1.4  billion in  2019,  from  $1.2  billion in  2018.  The  $208  million  increase was  primarily  attributable  to  an  $85
million,  or  21%,  increase  in  multifamily  revenue.  The  multifamily  increase  was  due  to  upgrades  of  existing  customer  packages  to  higher  value  advertising
packages,  higher  volume  as  a  result  of  recent  investments  in  marketing,  and  to  a  lesser  extent,  growth  from  the  acquisitions  of  Cozy  and  OCP.  CoStar  Suite
revenues increased $73 million, or 13%, primarily due to further increases in pricing and, to a lesser extent, further market penetration and cross-selling of our
services.  Commercial  property  and  land  revenue  increased  $30 million,  or  17%,  primarily  due  to  growth  in  our  LoopNet  online  marketplace  services  of  $23
million, as well as, growth in our land and businesses for-sale services of $6 million. Information services revenue increased $21 million, or 31%, primarily due to
increased revenue of $13 million from our CoStar Real Estate Manager service offerings and $9 million due to the acquisition of STR.

Gross Profit. Gross profit increased to $1.1 billion in 2019, from $922 million in 2018. The gross profit percentage was 79% for 2019 compared to  77% for
2018 as revenues increased at a higher rate than cost of revenues. The increase in cost of revenues of $19 million, or 7%, was primarily due to additional merchant
fees and data and content costs of $9 million, primarily attributable to the acquisition of Cozy, additional personnel costs of $8 million and additional costs for
research equipment of $3 million. The increase from the prior year was partially offset by nonrecurring research personnel restructuring costs incurred in the prior
year of $3 million.

Selling and Marketing Expenses. Selling and marketing expenses increased to $409 million in 2019, from $360 million in 2018. The increase was primarily

attributable to $41 million in additional marketing spend, including $23 million in search engine marketing, $7 million in co-branding and $11 million in other
forms of marketing, primarily for Apartments.com. The increase was also due to a $5 million increase in personnel costs driven by increased headcount, partially
offset by higher severance and retention costs incurred in 2018 related to the acquisition of ForRent.

Software Development Expenses. Software development expenses increased to $126 million in 2019, from $101 million in 2018, and increased as a percentage
of revenues to 9% in 2019, compared to 8% in 2018. The increase in the amount of software development expense was primarily due to a $22 million increase in
personnel costs as a result of increased headcount to enhance our product offerings, including $2 million due to the acquisition of STR.

General  and  Administrative  Expenses.  General  and  administrative  expenses  increased to  $179 million in  2019,  from  $157 million in  2018,  and  remained
consistent as a percentage of revenues at 13% in 2019 and 2018. The increase in general and administrative expenses was primarily due to personnel costs of $12
million  due  to  increased  headcount,  $4  million  as  a  result  of  the  acquisition  of  STR,  bad  debt  expense  of  $4  million,  additional  software  and  equipment  of  $4
million, depreciation expense of $2 million and travel and conference expenses of $1 million each, partially offset by a $5 million decrease in professional services.

Customer Base Amortization Expense. Customer base amortization expense  increased to $34 million in 2019, from $31 million in 2018, and decreased as a

percentage of revenues to 2% in 2019, compared to 3% in 2018. The increase in customer base amortization expense was primarily due to the STR acquisition.

Interest  and  Other  Income. Interest  and  other  income  increased to  $30 million in  2019, from $13 million in  2018.  The  increase  was  primarily  due  to  $11
million in legal settlement proceeds received during 2019, as well as, higher rates of return and average cash and cash equivalent balances during 2019 compared
to 2018.

Interest and Other Expense. Interest and other expense remained consistent for 2019 and 2018, and primarily consists of commitment fees and amortization of

debt issuance costs.

Income Tax Expense. Income tax expense increased to $76 million in 2019, from $46 million in 2018. The increase was primarily due to higher income before
income taxes for 2019, and to a lesser extent, discrete items for higher state research and development tax credits recognized for 2018. The effective tax rate for
2019 was 19%, compared to 16% in 2018 and lower than the statutory rates due to discrete items including research and development credits as well as excess tax
benefits.

For  a  comparison  of  the  Company’s  results  of  operations  for  the  fiscal  year  ended  December 31, 2018 to  the  year  ended  December 31, 2017,  see  Item  7,
Management’s  Discussion  and  Analysis  of  Financial  Condition  and  Results  of  Operations  in  the  Company’s  Annual  Report  on  Form  10-K  for  the  year
ended December 31, 2018, which was filed with the U.S. Securities and Exchange Commission on February 28, 2019.

Comparison of Business Segment Results for Year Ended December 31, 2019 and Year Ended December 31, 2018

We manage our business geographically in two operating segments, with the primary areas of measurement and decision-making being North America, which
includes the U.S. and Canada, and International, which primarily includes Europe, Asia-Pacific and Latin America. Management relies on an internal management
reporting process that provides revenue and operating segment net income before interest and other income (expense), loss on debt extinguishment, income taxes,
depreciation  and  amortization  (“EBITDA”).  Management  believes  that  operating  segment  EBITDA  is  an  appropriate  measure  for  evaluating  the  operational
performance  of  our  operating  segments.  EBITDA  is  used  by  management  to  internally  measure  operating  and  management  performance  and  to  evaluate  the
performance of the business. However, this measure should be considered in addition to, not as a substitute for or superior to, income from operations or other
measures of financial performance prepared in accordance with GAAP. 

Segment  Revenues.  North  America  revenues  increased  to  $1.4  billion for  the  year  ended  December  31,  2019,  from  $1.2  billion for  the  year  ended
December 31, 2018. The increase in North America revenues was primarily due to a $85 million increase in multifamily  revenues driven by the sale of higher
value advertising packages and volume, and to a lesser extent, the acquisition of Cozy, and continued organic growth in CoStar Suite revenues of  $71 million.
There were also increases of $29 million and $18 million in commercial property and land and information services, respectively, primarily due to growth in our
LoopNet and CoStar Real Estate Manager service offerings, and to a lesser extent, the acquisition of STR. International revenues increased to $40 million for the
year ended December 31, 2019, from $35 million for the year ended December 31, 2018. The increase in International revenues was primarily due the acquisition
of STR and further growth of our subscription-based services.

Segment  EBITDA. North  America  EBITDA  increased to  $452  million for  the  year  ended  December  31,  2019,  from  $358  million for  the  year  ended

December 31, 2018. The increase in North America EBITDA was due primarily to an increase in revenues, partially offset by increases in personnel and marketing
costs. International EBITDA remained consistent at a loss of $7 million for the years ended December 31, 2019 and December 31, 2018.

Liquidity and Capital Resources

Our principal  sources  of  liquidity  are  cash  and  cash  equivalents  and  cash  from  operations.  We  also  have  access  to  $750 million from our revolving credit
facility. In total, cash and cash equivalents decreased by $30 million at  December 31, 2019 compared to  December 31, 2018, primarily due to the cash paid in
connection with the acquisitions of STR and OCP for an aggregate amount of $438 million, cash paid for purchases of property and equipment of $46 million and
repurchases of restricted stock to satisfy employee tax withholding obligations upon vesting of restricted stock awards valued at approximately $28 million. These
decreases  were  partially  offset  by  net  cash  generated  from  operations  of  $458  million and  proceeds  from  the  exercise  of  employee  stock  options  of
approximately $25 million.

Net cash provided by operating activities for the year ended December 31, 2019 was $458 million compared to $335 million for the year ended December 31,
2018. The approximately $123 million increase from  December 31, 2018 to  December 31, 2019 was primarily due to an  increase in net income of  $77 million
including an increase in other non-cash expenses such as stock-based compensation expense and the timing of collections for accounts receivable, partially offset
by $15 million placed into an escrow account for deferred compensation for certain STR employees.

Net cash used in investing activities for the year ended December 31, 2019 was $484 million compared to $448 million for the year ended December 31, 2018.
The $36 million increase in cash used in investing activities was primarily due to approximately $418 million of net cash paid to acquire ForRent, Cozy and Realla
during 2018, compared to $438 million net cash paid during 2019 for the STR and OCP acquisitions. During 2019, we made capital expenditures of approximately
$46 million compared  to approximately  $30 million during  2018. The increase  in capital  expenditures  during  the  year  ended  December 31, 2019 was partially
driven by the purchase of a corporate aircraft, which is principally used for business travel by our executives.

Net cash used in financing activities for the year ended December 31, 2019 was $4 million compared to net cash provided by financing activities of $3 million
for  the  year  ended  December  31,  2018.  This  $7 million increase in  cash  used  in  financing  activities  in  2019 compared  to  2018 was  primarily  due  to  higher
repurchases  of  restricted  stock  to  satisfy  employee  tax  withholding  obligations  upon  vesting  of  restricted  stock  awards  of  $3 million,  as  well  as  a  decrease  in
proceeds from the exercise of employee stock options of $2 million.

Our future capital requirements will depend on many factors, including, among others, our operating results, expansion and integration efforts, and our level of
acquisition activity or other strategic transactions. To date, we have grown in part by acquiring other companies, and we expect to continue to make acquisitions.
On February 11, 2020, our wholly owned subsidiary entered into a purchase agreement to acquire all of the equity interests of reorganized RentPath, following an
internal restructuring pursuant to a chapter 11 plan of reorganization, for $588 million in cash. The purchase agreement requires us to pay a $59 million fee in the
event the purchase agreement is terminated prior to closing under specified circumstances. The acquisition will be funded using cash on hand. See Note 19 to the
accompanying Notes to the Consolidated Financial Statements included in Part IV of this Annual Report on Form 10-K for further discussion. Based on current
plans, we believe that our available cash combined with positive cash flow provided by operating activities should be sufficient to fund our operations for at least
the next twelve months.

Contractual Obligations.  The  following  table  summarizes  our  principal  contractual  obligations  at  December  31,  2019 and  the  effect  such  obligations  are

expected to have on our liquidity and cash flows in future periods (in thousands):

Critical Accounting Policies

The  preparation  of  financial  statements  and  related  disclosures  in  conformity  with  U.S.  generally  accepted  accounting  principles  (“GAAP”)  requires
management to make estimates and assumptions that affect the reported amounts of assets and liabilities, the disclosure of contingent assets and liabilities at the
date of the financial statements and revenues and expenses during the period reported. The following accounting policies involve a “critical accounting estimate”
because  they  are  particularly  dependent  on  estimates  and  assumptions  made  by  management  about  matters  that  are  highly  uncertain  at  the  time  the  accounting
estimates  are  made.  In  addition,  while  we  have  used  our  best  estimates  based  on  facts  and  circumstances  available  to  us  at  the  time,  different  acceptable
assumptions would yield different results. Changes in the accounting estimates are reasonably likely to occur from period to period, which may have a material
impact on the presentation of our financial condition and results of operations. We review these estimates and assumptions periodically and reflect the effects of
revisions in the period that they are determined to be necessary. We consider policies relating to the following matters to be critical accounting policies:

•
•
•
•

Long-lived assets, intangible assets and goodwill
Revenue recognition
Income taxes
Business combinations

With respect to our accounting policy for long-lived assets, intangible assets and goodwill, we further supplement in Note 2 of the Notes to the Consolidated

Financial Statements included in this Annual Report on Form 10-K with the following:

We assess the impairment of long-lived assets, identifiable intangibles and goodwill whenever events or changes in circumstances indicate that the carrying
value may not be recoverable. Judgments made by management relate to the expected useful lives of long-lived assets and our ability to recover the carrying value
of such assets. The accuracy of these judgments may be adversely affected by several factors, including the factors listed below:

•
•
•
•

Significant underperformance relative to historical or projected future operating results;
Significant changes in the manner of our use of the acquired assets or the strategy for our overall business;
Significant negative industry or economic trends; or
Significant decline in our market capitalization relative to net book value for a sustained period.

When we determine that the carrying value of long-lived and identifiable intangible assets may not be recovered based upon the existence of one or more of

the above indicators, we test for impairment.

Goodwill and identifiable intangible assets that are not subject to amortization are tested annually for impairment by each reporting unit on October 1 of each

year and are also tested for impairment more frequently based upon the existence of one or more of the above indicators. 

Goodwill represents the excess of costs over the fair value of assets of acquired businesses. Goodwill is not amortized, but instead tested for impairment at
least annually by each reporting unit. We may first assess qualitative factors to evaluate whether it is more likely than not that the fair value of a reporting unit is
less than its carrying amount or elect to bypass such assessment. If it is determined that it is more likely than not that the fair value of a reporting unit is less than
its carrying value, or we elect to bypass such assessment, we then determine the fair value of each reporting unit. We estimate the fair value of each reporting unit
based on a projected discounted cash flow model that includes significant assumptions and estimates including our discount rate, growth rate and future financial
performance. Assumptions about the discount rate are based on a weighted average cost of capital for comparable companies. Assumptions about the growth rate
and  future  financial  performance  of  a  reporting  unit  are  based  on  our  forecasts,  business  plans,  economic  projections  and  anticipated  future  cash  flows.  These
assumptions are subject to change from period to period and could be adversely impacted by the uncertainty surrounding global market conditions, commercial real
estate conditions and the competitive environment in which we operate. Changes in these or other factors could negatively affect our reporting units' fair value and
potentially result in impairment charges. Such impairment charges could have an adverse effect on our results of operations.

The fair value of each reporting unit is compared to the carrying amount of the reporting unit. If the carrying value of the reporting unit exceeds the fair value,
then an impairment loss is recognized for the difference. We estimate the fair value of our reporting units based on a projected discounted cash flow method using
a discount rate determined by our management to be commensurate with the risk in our current business model. As of October 1, 2019, we assessed the relevant
qualitative factors and concluded that it was not more likely than not that the fair value of our reporting units was less than their respective carrying amounts. There
have been no events or changes in circumstances as a result of our qualitative impairment analysis on October 1, 2019, that would indicate that the carrying value
of each reporting unit may not be recoverable.

and assumptions involved in their application, see Note 2 to the accompanying consolidated financial statements included in this Annual Report on Form 10-K.

Recent Accounting Pronouncements

See  Note  2 of  the  Notes  to  Consolidated  Financial  Statements  included  in  this  Annual  Report  on  Form  10-K  for  information  on  recent  accounting

pronouncements, including the expected dates of adoption.

Item 7A.

Quantitative and Qualitative Disclosures About Market Risk

We provide information, analytics and online marketplace services to commercial real estate and related business communities within the regions where we
operate which primarily  include, North America,  Europe, Asia-Pacific and Latin America. The functional  currency for a majority  of our operations is the local
currency, with the exception of certain STR international locations for which the functional currency is the British Pound.

Fluctuations in the British Pound, Canadian dollar and Euro may have an impact on our business, results of operations and financial position. For the year
ended December 31, 2019 and December 31, 2018, revenues denominated in foreign currencies were approximately 4% and 3%, respectively, of total revenue. For
the year ended December 31, 2019 and  December 31, 2018, our revenues would have decreased  by approximately  $6 million and  $3 million if  the  U.S. dollar
exchange rate used strengthened by 10%. For the year ended December 31, 2019 and December 31, 2018, our revenues would have increased by approximately $6
million and $3 million if the U.S. dollar exchange rate used weakened by 10%. Fluctuations in the exchange rates of revenues denominated in any other foreign
currencies  would  have  had  an  immaterial  impact  on  our  consolidated  results.  In  addition,  we  have  assets  and  liabilities  denominated  in  foreign  currencies.  We
currently do not use financial instruments to hedge our exposure to exchange rate fluctuations with respect to our foreign subsidiaries. We may seek to enter into
hedging transactions in the future to reduce our exposure to exchange rate fluctuations, but we may be unable to enter into hedging transactions successfully, on
acceptable  terms  or  at  all.  As  of  December  31,  2019,  accumulated  other  comprehensive  loss  included  a  loss  from  foreign  currency  translation  adjustments  of
approximately $8 million.

We  do  not  believe  we  have  material  exposure  to  market  risks  associated  with  changes  in  interest  rates  related  to  cash  equivalent  securities  held  as  of
December 31, 2019. As of December 31, 2019, we had $1.1 billion of cash and cash equivalents. If there is an increase or decrease in interest rates, there will be a
corresponding increase or decrease in the amount of interest earned on our cash and cash equivalents.

Included within our short-term and long-term investments are investments in mostly AAA-rated student loan ARS. These securities are primarily securities
supported by guarantees from the FFELP of the U.S. Department of Education. As of December 31, 2019, $11 million of our investments in ARS failed to settle at
auction. As a result, we may not be able to sell these investments at par value until a future auction on these investments is successful. In the event we need to
immediately liquidate these investments, we may have to locate a buyer outside the auction process, who may be unwilling to purchase the investments at par,
resulting in a loss. If the issuers are unable to successfully close future auctions and/or their credit ratings deteriorate, we may be required to adjust the carrying
value  of  these  investments  as  a  temporary  impairment  and  recognize  a  greater  unrealized  loss  in  accumulated  other  comprehensive  loss  or  as  an  other-than-
temporary impairment charge to earnings. Based on our ability to access our cash and cash equivalents, and our expected operating cash flows, we do not anticipate
having to sell these securities below par value in order to operate our business in the foreseeable future. See Notes 5 and 6 to the Notes to Consolidated Financial
Statements included in this Annual Report on Form 10-K for further discussion.

We had approximately $2.3 billion of goodwill and intangible assets as of December 31, 2019. As of December 31, 2019, we believe our intangible assets will
be  recoverable;  however,  changes  in  the  economy,  the  business  in  which  we  operate  and  our  own  relative  performance  could  change  the  assumptions  used  to
evaluate intangible asset recoverability. In the event that we determine that an asset has been impaired, we would recognize an impairment charge equal to the
amount by which the carrying amount of the assets exceeds the fair value of the asset. We continue to monitor these assumptions and their effect on the estimated
recoverability of our intangible assets.

We maintain disclosure controls and procedures that are designed to ensure that information required to be disclosed in our reports filed or submitted under the
Exchange Act 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  for  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 is required to apply its judgment in evaluating the cost-benefit relationship of possible controls and procedures.

We  carried  out  an  evaluation,  under  the  supervision  and  with  the  participation  of  our  management,  including  our  Chief  Executive  Officer  and  our  Chief
Financial Officer, of the effectiveness of the design and operation of our disclosure controls and procedures as of the end of the fiscal year. Based on the foregoing,
our Chief Executive Officer and Chief Financial Officer concluded that our disclosure controls and procedures were effective and were operating at a reasonable
assurance level as of December 31, 2019.

During  2019,  we  continued  to  implement  a  financial  system  that  is  designed  to  improve  the  efficiency  and  effectiveness  of  our  operational  and  financial
accounting processes. This implementation is expected to continue beyond 2020. Consistent with any process change that we implement, the design of the internal
controls has and will continue to be evaluated for effectiveness as part of our overall assessment of the effectiveness of our disclosure controls and procedures. We
expect that the implementation of this system will improve our internal controls over financial reporting.

Other than the implementation of a new financial system noted above, there have been no changes in our internal control over financial reporting during our

most recent fiscal year that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

Management’s Report on Internal Control over Financial Reporting

Management  of  CoStar  is  responsible  for  establishing  and  maintaining  adequate  internal  control  over  financial  reporting  and  for  the  assessment  of  the
effectiveness  of  internal  control  over  financial  reporting.  As  defined  by  the  Securities  and  Exchange  Commission,  internal  control  over  financial  reporting  is  a
process designed by, or supervised by, the Company’s principal executive and principal financial officers, to provide reasonable assurance regarding the reliability
of financial reporting and the preparation of financial statements in accordance with GAAP.

The Company’s internal control over financial reporting is supported by written 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  Company’s  assets;  (2)  provide  reasonable  assurance  that  transactions  are
recorded as necessary to permit preparation of financial statements in accordance with GAAP, and that receipts and expenditures of the Company are being made
only in accordance with authorizations of the Company’s management and directors; 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.  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  connection  with  the  preparation  of  the  Company's  annual  financial  statements,  management  of  the  Company  has  undertaken  an  assessment  of  the
effectiveness  of the Company’s  internal  control  over  financial  reporting  as of  December 31, 2019 based on criteria  established  in Internal Control – Integrated
Framework (2013 framework) issued by the Committee of Sponsoring

47

 
Organizations of the Treadway Commission (“the COSO Framework”). Management's assessment included an evaluation of the design of the Company's internal
control over financial reporting and testing of the operational effectiveness of the Company's internal control over financial reporting.

Based on this assessment, management has concluded that the Company's internal control over financial reporting was effective as of December 31, 2019.

Ernst & Young LLP, the independent registered public accounting firm that audited the Company's financial statements included in this report, has issued an

attestation report on the effectiveness of internal control over financial reporting, a copy of which is included in this Annual Report on Form 10-K.

On June 12, 2019, we completed the acquisition of OCP and on October 22, 2019, we completed the acquisition of STR. As permitted by the Securities and
Exchange Commission, we have elected to exclude the internal controls of these acquisitions that have not been integrated into our existing processes and controls
from our assessment of the effectiveness of internal control over financial reporting as of December 31, 2019. The excluded aggregate financial position of OCP
and STR represented less than 1% of our total assets as of December 31, 2019, and less than 1% and 2% of our revenues and net income, respectively, for the year
then  ended.  We  will  include  the  internal  controls  of  OCP  and  STR  in  our  assessment  of  the  effectiveness  of  our  internal  control  over  financial  reporting  as  of
December 31, 2020.

Report of Independent Registered Public Accounting Firm

The Board of Directors and Stockholders of CoStar Group, Inc.

Opinion on the Financial Statements

We have audited the accompanying consolidated balance sheets of CoStar Group, Inc. (the Company) as of December 31, 2019 and 2018, the related consolidated
statements of operations, comprehensive income, stockholders' equity and cash flows for each of the three years in the period ended December 31, 2019, and the
related notes and the financial statement schedule listed in the Index at Item 15(a)(2) (collectively referred to as the “financial statements”). In our opinion, the
financial statements present fairly, in all material respects, the consolidated financial position of the Company at December 31, 2019 and 2018, and the
consolidated results of its operations and its cash flows for each of the three years in the period ended December 31, 2019, in conformity with U.S. generally
accepted accounting principles.

We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States) (PCAOB), the Company's internal
control over financial reporting as of December 31, 2019, based on criteria established in Internal Control-Integrated Framework issued by the Committee of
Sponsoring Organizations of the Treadway Commission (2013 framework), and our report dated February 26, 2020 expressed an unqualified opinion thereon.

Adoption of ASU No. 2014-09

As discussed in Note 2 to the consolidated financial statements, the Company changed its method for recognizing revenue in 2018 due to the adoption of
Accounting Standards Update (ASU) No. 2014-09, Revenue from Contracts with Customers (Topic 606), and the related amendments.

Adoption of ASU No. 2016-02

As discussed in Note 2 to the consolidated financial statements, the Company changed its method for accounting for leases in 2019 due to the adoption of
Accounting Standards Update (ASU) No. 2016-02, Leases (Topic 842), and the related amendments.

Basis for Opinion

These financial statements are the responsibility of the Company's management. Our responsibility is to express an opinion on the Company’s financial statements
based on our audits. We are a public accounting firm registered with the PCAOB and are required to be independent with respect to the Company in accordance
with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.

We conducted our audits in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable
assurance about whether the financial statements are free of material misstatement, whether due to error or fraud. Our audits included performing procedures to
assess the risks of material misstatement of the financial statements, whether due to error or fraud, and performing procedures that respond to those risks. Such
procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the financial statements. Our audits also included evaluating the
accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the financial statements. We believe
that our audits provide a reasonable basis for our opinion.

Critical Audit Matter

The critical audit matter communicated below is a matter arising from the current period audit of the financial statements that was communicated or required to be
communicated to the audit committee and that: (1) relates to accounts or disclosures that are material to the financial statements and (2) involved our especially
challenging, subjective or complex judgments. The communication of the critical audit matter does not alter in any way our opinion on the consolidated financial
statements, taken as a whole, and we are not, by communicating the critical audit matter below, providing a separate opinion on the critical audit matter or on the
accounts or disclosures to which it relates.

Valuation of Acquired Intangible Assets

Description of the
Matter

As described in Note 4 to the consolidated financial statements, during the year ended December 31, 2019, the Company
completed the acquisition of STR, Inc. and STR Global, Ltd. (together with STR, Inc. referred to as “STR”) for $435
million in cash. The Company’s accounting for the acquisition included determining the fair value of the acquired
intangible assets including customer relationships of $139 million.

Auditing the accounting for the acquired intangible assets of STR involved complex auditor judgment due to the estimation
required in management’s determination of the fair value. The estimation was significant primarily due to the sensitivity of
the respective fair values to the underlying assumptions, including discount rates, projected revenue growth rates, customer
attrition rates and projected profit margins. These significant assumptions are forward-looking and could be affected by
future economic and market conditions.

How We
Addressed the
Matter in Our
Audit

We obtained an understanding, evaluated the design and tested the operating effectiveness of controls over the Company’s
process for accounting for acquired intangible assets. For example, we tested controls over management’s review of the
valuation model and significant assumptions used in the valuation as well as controls over the completeness and accuracy
of the data used in the model and assumptions.

To test the fair value of these acquired intangible assets, our audit procedures included, among others, evaluating the
Company's use of valuation methodologies, evaluating the significant assumptions, evaluating the prospective financial
information and testing the completeness and accuracy of underlying data. We involved our valuation specialists to assist in
testing certain significant assumptions used to value the acquired intangible assets. For example, we compared the
significant assumptions to current industry and market trends, historical results of the acquired business and to other
relevant factors. We also performed sensitivity analyses of the significant assumptions to evaluate the change in the fair
value resulting from changes in the assumptions.

Report of Independent Registered Public Accounting Firm

The Board of Directors and Stockholders of CoStar Group, Inc.

Opinion on Internal Control over Financial Reporting

We have audited CoStar Group, Inc.’s internal control over financial reporting as of December 31, 2019, based on criteria established in Internal Control-Integrated
Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (2013 framework) (the COSO criteria). In our opinion, CoStar
Group, Inc. (the Company) maintained, in all material respects, effective internal control over financial reporting as of December 31, 2019, based on the COSO
criteria.

As indicated in the accompanying Management’s Report on Internal Control over Financial Reporting, management’s assessment of and conclusion on the
effectiveness of internal control over financial reporting did not include the internal controls of Off Campus Partners, LLC, STR, Inc. and STR Global, Ltd., which
are included in the 2019 consolidated financial statements of CoStar Group, Inc., and collectively constituted less than 1% of total assets as of December 31, 2019
and less than 1% and 2% of total revenues and net income, respectively, for the year then ended. Our audit of internal control over financial reporting of CoStar
Group, Inc. also did not include an evaluation of the internal control over financial reporting of Off Campus Partners, LLC, STR, Inc. and STR Global, Ltd.

We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States) (PCAOB), the consolidated balance
sheets of CoStar Group, Inc. as of December 31, 2019 and 2018, the related consolidated statements of operations, comprehensive income, stockholders' equity and
cash flows for each of the three years in the period ended December 31, 2019 and the related notes and the financial statement schedule listed in the Index at
Item 15(a)(2) (collectively referred to as the “financial statements”) of CoStar Group, Inc. and our report dated February 26, 2020 expressed an unqualified opinion
thereon.

Basis for Opinion

The Company’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 are a public accounting firm registered with the PCAOB and are
required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the
Securities and Exchange Commission and the PCAOB.

We conducted our audit in accordance with the standards of the PCAOB. 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.

Definition and Limitations of Internal Control Over Financial Reporting

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.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

December 31, 2019

1.

ORGANIZATION

CoStar Group, Inc. (the “Company” or “CoStar”) provides information, analytics and online marketplace services to the commercial real estate and related
business  community  through  its  comprehensive,  proprietary  database  of  commercial  real  estate  information.  The  Company  provides  online  marketplaces  for
commercial  real  estate,  apartment  rentals,  lands  for-sale  and  businesses  for-sale,  and  its  services  are  typically  distributed  to its  clients  under  subscription-based
license agreements that renew automatically, a majority of which have a term of at least one year. The Company operates within two operating segments, North
America, which includes the United States (“U.S.”) and Canada, and International, which primarily includes Europe, Asia-Pacific and Latin America.

On October 22, 2019, the Company acquired STR, Inc. and STR Global, Ltd. (together with STR, Inc., referred to as "STR"). STR provides benchmarking and

analytics for the hospitality industry. See Note 4 to the accompanying Notes to the Consolidated Financial Statements for further discussion of this acquisition.

2.

SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

Basis of Presentation

The consolidated financial statements include the accounts of the Company and its wholly owned subsidiaries. All intercompany balances and transactions

have been eliminated in consolidation. Accounting policies are consistent for each operating segment.

Use of Estimates

The preparation of financial statements in conformity with U.S. generally accepted accounting principles (“GAAP”) requires management to make estimates
and assumptions that affect the amounts reported in the financial statements and accompanying notes. On an ongoing basis, the Company evaluates its estimates
and assumptions, including those related to revenue recognition, allowance for doubtful accounts, the useful lives and recoverability of long-lived and intangible
assets,  and  goodwill;  income  taxes,  the  fair  value  of  auction  rate  securities,  accounting  for  business  combinations,  stock-based  compensation,  estimating  the
Company's incremental borrowing rate for its leases, and contingencies, among others. The Company bases these estimates on historical and anticipated results,
trends,  and  various  other  assumptions  that  it  believes  are  reasonable,  including  assumptions  as  to  future  events.  These  estimates  form  the  basis  for  making
judgments about the carrying values of assets and liabilities and recorded revenues and expenses. Actual results could differ from these estimates.

Revenue Recognition

The  Company  derives  revenues  primarily  by  (i)  providing  access  to  its  proprietary  database  of  commercial  real  estate  information  and  (ii)  providing  online
marketplaces for professional property management companies, property owners, brokers and landlords, in each case typically through a fixed monthly fee for its
subscription-based services. The Company's subscription-based services consist primarily of information, analytics and online marketplace services offered over
the Internet to commercial real estate industry and related professionals. Subscription contract rates are based on the number of sites, number of users, organization
size, the client’s  business focus, geography, the number and types of services  to which a client  subscribes, the number of properties a client  advertises and the
prominence  and  placement  of  a  client's  advertised  properties  in  the  search  results.  The  Company’s  subscription-based  license  agreements  typically  renew
automatically, and a majority have a term of at least one year.

The  Company  also  provides  market  research,  portfolio  and  debt  analysis,  management  and  reporting  capabilities,  and  real  estate  and  lease  management
solutions, including lease administration and abstraction services, to commercial customers, real estate investors, lenders and hospitality customers via our other
service offerings.

The Company analyzes contracts to determine the appropriate revenue recognition using the following steps: (i) identification of contracts with customers, (ii)
identification of distinct performance obligations in the contract, (iii) determination of contract transaction price, (iv) allocation of contract transaction price to the
performance obligations, and (v) determination of revenue recognition based on timing of satisfaction of the performance obligation(s).

F-12

  
COSTAR GROUP, INC.
NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

The Company recognizes revenues upon the satisfaction of its performance obligation(s) (upon transfer of control of promised services to its customers) in an
amount that reflects the consideration to which it expects to be entitled to in exchange for those services. Revenues from subscription-based services are recognized
on a straight-line basis over the term of the agreement.

In limited circumstances, the Company's contracts with customers include promises to transfer multiple services, such as contracts for its subscription-based
services and professional services. For these contracts, the Company accounts for individual performance obligations separately if they are distinct, which involves
the determination of the standalone selling price for each distinct performance obligation.

Deferred  revenue  results  from  amounts  billed  in  advance  to  customers  or  cash  received  from  customers  in  advance  of  the  Company's  fulfillment  of  its

performance obligation(s) and is recognized over the term of the license agreement.

Contract assets represent a conditional right to consideration for satisfied performance obligations that become a receivable when the conditions are satisfied.

Contract assets are generated when contractual billing schedules differ from revenue recognition timing.

Certain sales commissions are considered incremental and recoverable costs of obtaining a contract with a customer. Sales commissions incurred for obtaining
new contracts are deferred and then amortized as selling and marketing expenses on a straight-line basis over a period of benefit that the Company has determined
to  be  three  years.  The  three-year  amortization  period  was  determined  based  on  several  factors,  including  the  nature  of  the  technology  and  proprietary  data
underlying the services being purchased, customer contract renewal rates and industry competition. Certain commission costs are not capitalized as they do not
represent incremental costs of obtaining a contract. See Note 3 for further discussion of the Company's revenue recognition.

On  January  1,  2018,  the  Company  adopted  Accounting  Standards  Update  (“ASU")  2014-09,  Revenue  from  Contracts  with  Customers,  later  codified  as
Accounting Standards Codification 606 ("ASC 606") using the modified retrospective method. Operating results for periods subsequent to December 31, 2017 are
presented under ASC 606, while prior period amounts are not adjusted and continue to be reported in accordance with the Company’s historical accounting policies
prior to adoption. For details about the Company’s revenue recognition policy prior to the adoption of  ASC 606, refer to the Company’s Annual Report on Form
10-K for the year ended December 31, 2017, filed with the Securities and Exchange Commission on February 23, 2018.

Cost of Revenues

Cost of revenues principally consists of salaries, benefits, bonuses, and stock-based compensation expenses for the Company’s researchers who collect and
analyze the commercial real estate data that is the basis for the Company’s information, analytics and online marketplaces. Additionally, cost of revenues includes
the cost of data from third-party data sources, credit card and other transaction fees relating to processing customer transactions, which are expensed as incurred,
operating lease costs and the amortization of acquired trade names, technology and other intangible assets.

Foreign Currency Translation

The Company’s reporting currency is the U.S. dollar. The functional currency for the majority of its operations is the local currency, with the exception of
certain international locations of STR for which the functional currency is the British Pound. Assets and liabilities denominated in a foreign currency are translated
into  U.S.  dollars  using  the  exchange  rates  in  effect  as  of  the  balance  sheet  date.  Gains  and  losses  resulting  from  translation  are  included  in  accumulated  other
comprehensive loss. Currency gains and losses on the translation of intercompany loans made to foreign subsidiaries that are of a long-term investment nature are
also  included  in  accumulated  other  comprehensive  loss.  Net  gains  or  losses  resulting  from  transactions  denominated  in  a  currency  other  than  the  functional
currency of the entity are included in interest and other income (expense) in the consolidated statements of operations using the average exchange rates in effect
during the period. There were no material gains or losses from foreign currency exchange transactions for the years ended December 31, 2019, 2018, and 2017.

Advertising Costs

The Company expenses advertising costs as incurred. Advertising costs include e-commerce, television, radio, print and other media advertising. Advertising

costs were approximately $164 million, $124 million and $104 million for the years ended December 31, 2019, 2018 and 2017, respectively.

Income Taxes

Deferred income taxes result from temporary differences between the tax basis of assets and liabilities and the basis reported in the Company’s consolidated
financial  statements.  Deferred  tax  liabilities  and  assets  are  determined  based  on  the  difference  between  the  financial  statement  and  the  tax  basis  of  assets  and
liabilities  using  enacted  rates  in  effect  during  the  year  in  which  the  Company  expects  differences  to  reverse.  Valuation  allowances  are  provided  against  assets,
including net operating losses, if the Company determines it is more likely than not that some portion or all of an asset may not be realized. Interest and penalties
related to income tax matters are recognized in income tax expense.

The Company has elected to record the global intangible low taxed income inclusion ("GILTI") under the current-period cost method.

See Note 12 for additional information regarding income taxes.

Net Income Per Share

Net income per share is computed by dividing net income by the weighted-average number of common shares outstanding during the period on a basic and
diluted basis. The weighted-average number of common shares outstanding during the period used for purposes of calculating basic earnings per share excludes
stock  options  and  stock-based  awards  which  include  restricted  stock  awards  that  vest  over  a  specific  service  period,  restricted  stock  awards  that  vest  based  on
achievement of a performance condition, restricted stock awards with a performance and a market condition, restricted stock units and Matching restricted stock
units  ("Matching  RSUs)  awarded  under  the  Company's  Management  Stock  Purchase  Plan  (the  “MSPP”).  The  Company’s  potentially  dilutive  securities  include
outstanding stock options and unvested restricted stock-based awards. Shares underlying unvested restricted stock-based awards that vest based on performance
and market conditions that have not been achieved as of the end of the period are not included in the computation of basic or diluted earnings per share. Diluted net
income per share considers the impact of potentially dilutive securities except when the inclusion of the potentially dilutive securities would have an anti-dilutive
effect. See Note 16 for additional information on the Company's calculation of net income per share.

Stock-Based Compensation

Equity instruments issued in exchange for services performed by officers, employees, and directors of the Company are accounted for using a fair-value based

method and the fair value of such equity instruments is recognized as expense in the consolidated statements of operations.

F-14

 
 
 
COSTAR GROUP, INC.
NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

For stock-based awards that vest over a specific service period, compensation expense is measured based on the fair value of the awards at the grant date, and

is recognized on a straight-line basis over the vesting period of the awards, net of an estimated forfeiture rate. For equity instruments that vest based on
achievement of a performance condition, stock-based compensation expense is recognized based on the expected achievement of the related performance
conditions at the end of each reporting period over the vesting period of the awards. If the Company's initial estimates of the achievement of the performance
conditions change, the related stock-based compensation expense and timing may fluctuate from period to period based on those estimates. If the performance
conditions are not met, no stock-based compensation expense will be recognized, and any previously recognized stock-based compensation expense will be
reversed. For awards with both a performance and a market condition, the Company estimates the fair value of each equity instrument granted on the date of grant
using a Monte-Carlo simulation model. This pricing model uses multiple simulations to evaluate the probability of achieving the market condition to calculate the
fair value of the awards.

(1) For the year ended December 31, 2018, stock-based compensation expense includes $1.5 million of expense related to the cash settlement of stock options in connection with the acquisition
of Cozy Services, Ltd. See Note 4 for details of the acquisition.

Cash and Cash Equivalents

The Company considers all highly liquid investments purchased with an original maturity of three months or less to be cash equivalents. Cash equivalents as

of December 31, 2019 and 2018 consisted of money market funds.

Investments

The Company determines the appropriate classification of debt and equity investments at the time of purchase and re-evaluates such designation as of each
balance  sheet  date.  The  Company's  investments  consist  of  long-term  variable  rate  debt  instruments  with  an  auction  reset  feature,  referred  to  as  auction  rate
securities, and are classified as available-for-sale. The Company's auction rate security investments are carried at fair value and any changes in unrealized holding
gains and losses, net of the related tax effect, are excluded from earnings and are reported as a separate component of accumulated other comprehensive loss in
stockholders’ equity until realized. A decline in market value of any investment below cost that is deemed to be other-than-temporary results in a reduction in
carrying  amount  to  fair  value.  The  impairment  is  charged  to  earnings  and  a  new  cost  basis  for  the  security  is  established.  Dividend  and  interest  income  are
recognized when earned.

Concentration of Credit Risk and Financial Instruments

The Company’s customer  base  creates  a lack  of dependence  on any individual  customer  that  mitigates  the risk of nonpayment  of the Company’s accounts
receivable.  No single customer  accounted  for more than 5% of the  Company’s  revenues  for  each  of  the  years  ended  December 31, 2019, 2018, and 2017. The
carrying amount of the accounts receivable approximates the net realizable value.

The Company holds cash at major financial institutions that often exceed Federal Deposit Insurance Corporation insured limits. The Company manages its
credit  risk  associated  with  cash  concentrations  by  concentrating  its  cash  deposits  in  high  quality  financial  institutions  and  by  periodically  evaluating  the  credit
quality  of  the  primary  financial  institutions  holding  such  deposits.  The  carrying  value  of  cash  approximates  fair  value.  Historically,  the  Company  has  not
experienced any losses due to such cash concentrations.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

Accounts receivable are recorded at the invoiced amount net of credits due. Accounts receivable payment terms vary and amounts due from customers are
stated in the financial statements net of an allowance for doubtful accounts. When evaluating the adequacy of the allowance for doubtful accounts, the Company
analyzes historical collection experience, changes in customer payment profiles and the aging of receivable balances, as well as current economic conditions, all of
which may affect a customer’s ability to pay. 

Leases

On  January  1,  2019,  the  Company  adopted  Accounting  Standards  Update  (“ASU”)  2016-02,  Leases,  later  codified  as  Accounting  Standards  Codification
("ASC") 842 ("ASC 842"), using the modified retrospective method. For periods presented prior to the adoption date, the Company continues to follow its previous
policy under ASC 840, Leases. For details about the Company’s lease policy prior to the adoption of ASC 842, refer to the Company’s Annual Report on Form 10-
K for the year ended December 31, 2017, filed with the Securities and Exchange Commission on February 23, 2018.

The determination of whether an arrangement contains a lease and the classification of a lease, if applicable, is made at lease commencement, at which time
the  Company  also  measures  and  recognizes  a  right-of-use  ("ROU")  asset,  representing  the  Company’s  right  to  use  the  underlying  asset,  and  a  lease  liability,
representing  the  Company’s  obligation  to  make  lease  payments  under  the  terms  of  the  arrangement.  For  the  purposes  of  recognizing  ROU  assets  and  lease
liabilities  associated with the Company’s leases, the Company has elected the practical expedient to not recognize a ROU asset or lease liability for short-term
leases, which are leases with a term of twelve months or less. The lease term is defined as the noncancelable portion of the lease term plus any periods covered by
an option to extend the lease if it is reasonably certain that that the option will be exercised.

In  determining  the  amount  of  lease  payments  used  in  measuring  ROU  assets  and  lease  liabilities,  the  Company  has  elected  the  practical  expedient  not  to
separate non-lease components from lease components for all classes of underlying assets. Consideration considered part of the lease payments used to measure
ROU assets and lease liabilities generally includes fixed payments and variable payments based on either an index or a rate. The ROU asset also includes any lease
prepayments, offset by lease incentives. ROU assets and liabilities are recognized at the lease commencement date based on the present value of lease payments
over the lease term. The rates implicit within the Company's leases are generally not determinable, therefore, the Company's incremental borrowing rate is used to
determine  the  present  value  of  lease  payments.  The  determination  of  the  Company’s  incremental  borrowing  rate  requires  judgment.  Because  the  Company
currently has no outstanding debt, the incremental borrowing rate for each lease is primarily based on publicly available information for companies within the same
industry  and  with  similar  credit  profiles  as  the  Company.  The  rate  is  then  adjusted  for  the  impact  of  collateralization,  the  lease  term  and  other  specific  terms
included in the Company’s lease arrangements. The incremental borrowing rate is determined at lease commencement, or as of January 1, 2019 for operating leases
in existence upon adoption of ASC 842. The incremental borrowing rate is subsequently reassessed upon a modification to the lease arrangement. ROU assets are
subsequently assessed for impairment in accordance with the Company’s accounting policy for long-lived assets.

Lease costs related to the Company's operating leases are generally recognized as a single ratable lease cost over the lease term.

See Note 7 for further discussion of the Company’s accounting for leases.

Property and Equipment, Net

Property and equipment are stated at cost, net of accumulated depreciation and amortization. All repairs and maintenance costs are expensed as incurred. Costs
related to acquisition of additional aircraft components or the replacement of existing aircraft components are capitalized and depreciated over the estimated useful
life of the aircraft or the added or replaced component, whichever is less. Depreciation and amortization are calculated on a straight-line basis over the following
estimated useful lives of the assets:

Leasehold improvements

Computer hardware and software

Furniture and office equipment

Vehicles

Aircraft

  Shorter of lease term or useful life

  Three to five years

  Five to ten years

  Five years

  Ten to twenty years

Qualifying  internal-use  software  costs  incurred  during  the  application  development  stage,  which  consist  primarily  of  internal  product  development  costs,
outside  services  and  purchased  software  license  costs  are  capitalized  and  amortized  over  the  estimated  useful  life  of  the  asset.  All  other  costs  are  expensed  as
incurred.

Long-Lived Assets, Intangible Assets and Goodwill

Long-lived  assets,  such  as  property  and  equipment,  and  purchased  intangibles  subject  to  amortization,  are  reviewed  for  impairment  whenever  events  or
changes  in  circumstances  indicate  that  the  carrying  amount  of  an  asset  may  not  be  recoverable.  Recoverability  of  assets  to  be  held  and  used  is  measured  by  a
comparison of the carrying amount of an asset to estimated undiscounted future cash flows expected to be generated by the asset or asset group. If the carrying
amount of an asset exceeds its estimated future cash flows, an impairment charge is recognized in the amount by which the carrying amount of the asset exceeds
the fair value of the asset.

Acquired technology and data, customer base assets, trade names and other intangible assets are related to the Company’s acquisitions (see Notes 4, 9 and 10).
Acquired technology and data is amortized on a straight-line basis over periods ranging from one year to eight years. Acquired intangible assets characterized as
customer  base  assets  consist  of  acquired  customer  contracts  and  the  related  customer  relationships  and  are  amortized  over  periods  ranging  from  five years to
thirteen years. Acquired customer bases are amortized on an accelerated or straight-line basis depending on the expected economic benefit of the intangible asset.
Acquired trade names and other intangible assets are amortized on a straight-line basis over periods ranging from one year to fifteen years.

Goodwill represents the future economic benefits arising from a business combination and is calculated as the excess of the purchase consideration paid in a
business combination over the fair value of assets acquired. Goodwill is not amortized, but instead is assigned to each of the Company's reporting units and tested
for impairment at least annually on October 1, or more frequently if an event or other circumstance indicates that the fair value of a reporting unit may be below its
carrying amount. If it is determined that it is more likely than not that the fair value of a reporting unit is less than its carrying value, or the Company elects to
bypass such assessment,  the Company then  determines  the fair  value of each  reporting  unit. The estimate  of the fair  value of each  reporting  unit is based on a
projected discounted cash flow model that includes significant assumptions and estimates including the discount rate, growth rate and future financial performance.
Assumptions about the discount rate  are based on a weighted average  cost of capital  for comparable  companies.  Assumptions about the growth rate  and future
financial performance of a reporting unit are based on the Company's forecasts, business plans, economic projections and anticipated future cash flows. The fair
value of each reporting unit is compared to the carrying amount of the reporting unit. If the carrying value of the reporting unit exceeds the fair value, then an
impairment loss is recognized for the difference.

Debt Issuance Costs

Costs incurred in connection with the issuance of long-term debt are deferred and amortized as interest expense over the term of the related debt using the
effective interest method for term debt and on a straight-line  basis for revolving debt. To the extent that debt is outstanding, these amounts are reflected in the
consolidated balance sheets as direct deductions from a combination of the current and long-term portions of debt for term debt and as current and long-term assets
for  costs  related  to  revolving  debt.  Upon  a  refinancing  or  amendment,  previously  capitalized  debt  issuance  costs  are  expensed  and  included  in  loss  on
extinguishment of debt if the Company determines that there has been a substantial modification of the related debt. If the Company determines that there has not
been a substantial modification of the related debt, any previously capitalized debt issuance costs are amortized as interest expense over the term of the new debt
instrument. See Note 11 for additional information on the Company's long-term debt and related debt issuance costs.

Business Combinations

The Company allocates the purchase consideration to the tangible assets acquired, liabilities assumed and intangible assets acquired based on their estimated
fair values. The purchase price is determined based on the fair value of the assets transferred, liabilities incurred and equity interests issued, after considering any
transactions that are separate from the business combination. The excess of the fair value of purchase consideration over the fair values of these identifiable assets
and liabilities is recorded as goodwill. Such valuations require management to make significant estimates and assumptions, especially with respect to intangible
assets and contingent liabilities. Significant estimates in valuing certain intangible assets include, but are not limited to, future expected cash flows from acquired
customer  bases,  acquired  technology  and  acquired  trade  names,  useful  lives,  royalty  rates  and  discount  rates.  Any  adjustments  to  provisional  amounts  that  are
identified  during  the  measurement  period  are  recorded  in  the  reporting  period  in  which  the  adjustment  amounts  are  determined.  Upon  the  conclusion  of  the
measurement period, any subsequent adjustments are recorded to earnings.

For a given acquisition, the Company may identify certain pre-acquisition contingencies as of the acquisition date and may extend its review and evaluation of
these  pre-acquisition  contingencies  throughout  the  measurement  period  in  order  to  obtain  sufficient  information  to  assess  whether  the  Company  includes  these
contingencies as a part of the fair value estimates of assets acquired and liabilities assumed and, if so, to determine their estimated amounts.

If the Company cannot reasonably determine the fair value of a pre-acquisition contingency (non-income tax related) by the end of the measurement period,
which is generally the case given the nature of such matters, the Company will recognize an asset or a liability for such pre-acquisition contingency if: (i) it is
probable  that  an  asset  existed  or  a  liability  had  been  assumed  at  the  acquisition  date  and  (ii)  the  amount  of  the  asset  or  liability  can  be  reasonably  estimated.
Subsequent  to  the  measurement  period,  changes  in  the  Company's  estimates  of  such  contingencies  will  affect  earnings  and  could  have  a  material  effect  on  its
results of operations and financial position.

In addition, uncertain tax positions and tax related valuation allowances assumed in connection with a business combination are initially estimated as of the
acquisition  date.  The  Company  reevaluates  these  items  based  upon  facts  and  circumstances  that  existed  as  of  the  acquisition  date,  with  any  adjustments  to  its
preliminary estimates being recorded to goodwill provided that the Company is within the measurement period. Subsequent to the measurement period, changes to
these uncertain tax positions and tax related valuation allowances will affect the Company's provision for income taxes in its consolidated statements of operations
and comprehensive income and could have a material impact on its results of operations and financial position.

Recent Accounting Pronouncements

Recently Adopted Accounting Pronouncements

On January 1, 2019, the Company adopted ASU 2016-02, Leases, using the modified retrospective method which allows for the application of the transition
provisions  at  the  beginning  of  the  period  of  adoption,  rather  than  at  the  beginning  of  the  earliest  comparative  period  presented  in  these  consolidated  financial
statements. As permitted by the guidance, the Company elected to retain the original lease classification and historical accounting for initial direct costs for leases
existing prior to the adoption date and did not reassess contracts entered into prior to the adoption date for the existence of a lease. The Company also did not
recognize ROU assets and lease liabilities for short-term leases, which are leases in existence as of the adoption date with an original term of twelve months or less.

As a result of the adoption of the standard, the Company recognized ROU assets of $116 million, including prepaid rent and deferred rent that was reclassified

and recognized as of the adoption date as a component of the ROU assets, as well as lease

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

liabilities  of  $150 million on  its  consolidated  balance  sheet.  The  assets  and  liabilities  recognized  upon  application  of  the  transition  provisions  were  primarily
associated with existing office leases. The Company also recognized a cumulative-effect adjustment to beginning retained earnings of $12 million, net of tax, as of
January 1, 2019, to recognize the remaining deferred gain on the sale-leaseback of the Company's corporate headquarters building, pursuant to the guidance in ASC
842.

Recent Accounting Pronouncements Not Yet Adopted

In December  2019, the  FASB issued  ASU 2019-12, Simplifying  the Accounting  for Income Taxes,  which is intended to simplify  various aspects related  to
accounting for income taxes. ASU 2019-12 removes certain exceptions to the general principles in ASC 740, Income Tax and also clarifies and amends existing
guidance to improve consistent application. ASU 2019-12 will be effective for public business entities for annual reporting periods beginning after December 15,
2020, and interim periods within those periods. Early adoption is permitted. The Company evaluated the impact of this guidance on its financial statements and
related disclosures and has elected to early adopt the guidance as of January 1, 2020. The guidance is not expected to have a material impact on the Company's
financial statements and related disclosures. The exceptions removed as part of the standard were determined to be not applicable to the Company. The primary
impact  from  adopting  the  standard  will  result  in  a  reclassification  of  franchise  taxes,  which  previously  had  been  classified  as  a  component  of  income  from
operations but will now be classified as a component of income tax expense beginning January 1, 2020.

In August 2018, the FASB issued ASU 2018-13, Fair Value Measurements (subsequent to adoption of ASU 2018-13, Fair Value Measurement). The ASU
was issued to eliminate certain disclosure requirements for fair value measurements, and add and modify other disclosure requirements, as part of its disclosure
framework project, including additional requirements for public companies to disclose certain information about the significant unobservable inputs for Level 3
fair value measurements. This guidance is effective for fiscal years beginning after December 15, 2019, including interim periods within those fiscal years. The
guidance is not expected to have a material impact on the Company's financial statements and related disclosures.

In August 2018, the FASB issued ASU 2018-15,  Intangibles - Goodwill and Other - Internal-Use Software (Subtopic 350-40): Customer’s Accounting for
Implementation  Costs  Incurred  in  a  Cloud  Computing  Arrangement  That  Is  a  Service  Contract.  ASU  2018-15  requires  a  customer  in  a  cloud  computing
arrangement that is a service contract to follow the internal-use software guidance in ASC 350-40 to determine which implementation costs to defer and recognize
as an asset. This guidance is effective for fiscal years beginning after December 15, 2019, including interim periods within those fiscal years. The guidance is not
expected to have a material impact on the Company's financial statements and related disclosures.

In  June  2016,  the  FASB  issued  ASU  2016-13,  Financial  Instruments-Credit  Losses  (Topic  326):  Measurement  of  Credit  Losses  on  Financial
Instruments,  which  is  designed  to  provide  financial  statement  users  with  more  information  about  the  expected  credit  losses  on  financial  instruments  and  other
commitments to extend credit held by a reporting entity at each reporting date. When determining such expected credit losses, the guidance requires companies to
apply a methodology that reflects expected credit losses and requires consideration of a broader range of reasonable and supportable information to inform credit
loss estimates. This guidance is effective on a modified retrospective basis for fiscal years beginning after December 15, 2019, including interim periods within

4.    ACQUISITIONS

STR, Inc. and STR Global Ltd.

On  October  22,  2019,  the  Company  acquired  all  of  the  issued  and  outstanding  equity  interests  of  STR  for  a  purchase  price  of  $435 million.  STR  is  a  global
provider  of  benchmarking  and  analytics  for  the  hospitality  industry.  The  combination  of  STR's  and  CoStar's  offerings  is  expected  to  allow  for  the  creation  of
valuable new and improved tools for industry participants. The Company applied the acquisition method to account for the STR transaction, which requires that
assets acquired and liabilities assumed be recorded at their fair values as of the acquisition date.

The  following  table  summarizes  the  amounts  recorded  for  acquired  assets  and  assumed  liabilities  recorded  at  their  fair  values  as  of  the  acquisition  date  (in

The net assets of STR were recorded at their estimated fair values. In valuing the acquired assets and assumed liabilities, fair value estimates were based primarily
on future expected cash flows, market rate assumptions for contractual obligations and appropriate discount rates. The purchase price allocation is preliminary,
subject to the final determination of net working capital as of the acquisition date and the Company's assessment of certain tax matters. The customer base assets
incorporated significant assumptions that had a material impact on the estimated fair value, such as discount rates, projected revenue growth rates, customer

Goodwill is calculated as the excess of the consideration transferred over the net assets recognized and represents the future economic benefits arising from
other assets acquired that could not be individually identified and separately recognized. Specifically, the goodwill recorded as part of the STR acquisition includes
but is not limited to: (i) the expected synergies and other benefits that the Company believes will result from combining its operations with STR's operations; and
(ii) any intangible assets that do not qualify for separate recognition, such as the assembled workforce. Goodwill recorded in connection with this acquisition is not
amortized,  but  is  subject  to  an  annual  impairment  test.  Of  the  $261 million of  goodwill  recorded  as  part  of  the  acquisition,  $159 million and  $102 million are
associated  with  the  Company's  North  America  and  International  operating  segments,  respectively.  The  goodwill  recognized  in  the  North  America  operating
segment is expected to be deductible for income tax purposes in future periods.

As part of the STR acquisition, the Company incurred $2 million of transaction costs. Additionally, the Company paid  $15 million cash into a cash escrow
account for deferred compensation for certain STR employees, to be paid to active employees after a defined one year period following the acquisition or when
earlier terminated without cause or terminated for good reason. In the event some or all of those employees are not entitled to their retention bonus, the funds will
be remitted to the seller. The Company is recognizing compensation expense for the deferred compensation over the one year post-combination period.

ForRent

On February 21, 2018, the Company acquired all of the issued and outstanding capital stock of DE Holdings, Inc., including its ForRent division ("ForRent"),
a  wholly  owned  subsidiary  of  Dominion  Enterprises  ("Seller"),  for  a  purchase  price  of  approximately  $376  million.  The  purchase  price  was  comprised  of
approximately $340 million in  cash  and  103,280 shares  of  Company  common  stock,  valued  at  approximately  $36 million.  ForRent's  primary  service  is  digital
advertising provided through a network of four multifamily websites. The acquisition has yielded increased revenue, significant cost synergies and an improved
competitive position in the industry. The Company applied the acquisition method to account for the ForRent transaction, which requires that assets acquired and
liabilities assumed be recorded at their fair values as of the acquisition date.

The  net  assets  of  ForRent  were  recorded  at  their  estimated  fair  values.  In  valuing  acquired  assets  and  assumed  liabilities,  fair  value  estimates  were  based
primarily  on  future  expected  cash  flows,  market  rate  assumptions  for  contractual  obligations  and  appropriate  discount  rates.  Measurement  period  adjustments
related to the determination of working capital as of the acquisition date and recognized in 2018 were not material.

The acquired customer base for the acquisition is composed of acquired customer contracts and the related customer relationships, and has a weighted average
estimated useful life of ten years. The acquired technology has an estimated useful life of three years. The acquired trade name has a weighted average estimated
useful life of ten years. The acquired building photography had an estimated useful life of one year. Amortization of the acquired customer base is recognized on
an accelerated basis related to the expected economic benefit of the intangible asset, while amortization of the acquired technology, acquired building photography
and  acquired  trade  names  and  other  intangible  assets  is  recognized  on  a  straight-line  basis  over  their  respective  estimated  useful  lives.  Goodwill  recorded  in
connection with this acquisition is not amortized, but is subject to an annual impairment test. The $267 million of goodwill recorded as part of the acquisition is
associated with the Company's North America operating segment. $8 million of goodwill that was recognized is expected to be deductible for income tax purposes
in future periods.

Goodwill is calculated as the excess of the consideration transferred over the net assets recognized and represents the future economic benefits arising from
other  assets  acquired  that  could  not  be  individually  identified  and  separately  recognized.  Specifically,  the  goodwill  recorded  as  part  of  the  ForRent  acquisition
includes but is not limited  to: (i) the expected  synergies  and other benefits  that the Company believes  will result from combining its operations  with ForRent's
operations; and (ii) any intangible assets that do not qualify for separate recognition, such as the assembled workforce.

Upon  acquisition,  the  Company  assessed  the  (i)  probability  of  a  contingent  sales  tax  liability  and  (ii)  a  state  uncertain  income  tax  position  liability  due  to
apportionment factors, and recorded accruals of $6 million and $2 million, respectively. The Company could not determine the fair value for the pre-acquisition
state sales tax liability and therefore estimated a liability in accordance with ASC 450, Contingencies, using a state-by-state assessment. The uncertain income tax
position  was determined  in  accordance  with  the  provisions  of  ASC  740,  Income  Tax, and  was recorded  as  part  of  the  purchase  price  allocation.  The  Seller  has
provided an indemnity for tax liabilities related to periods prior to the acquisition. The Seller's indemnification obligation for sales taxes in the state of Texas is
limited to approximately $2 million. The total sales tax and uncertain income tax indemnification assets established as of the acquisition date were $5 million and
$2 million, respectively. $0.9 million and $0.5 million of the contingent sales tax liability and related indemnification asset recognized as of the acquisition date
were reversed during 2019 and 2018, respectively, upon expiration of the statute of limitations applicable to the contingent sales tax liability. $0.6 million and $0.9
million of the uncertain income tax position liability and related indemnification asset recognized as of the acquisition date were reversed during  2019 and 2018,
respectively, upon expiration of the statute of limitations applicable to the uncertain income tax position.

As part of the ForRent acquisition, the Company incurred $3 million of transaction costs. Additionally, the Company paid $12 million cash into a cash escrow
account for retention compensation for certain ForRent employees, payable if they remained employed by the Company for a defined six-month period following
the acquisition or were earlier terminated without cause or resigned for good reason. In the event funds remained in the escrow account after the employees were
compensated and the defined

six-month period ended, those funds were remitted to the Seller. The Company expensed all of the retention compensation as the services were performed in the
post-combination period in 2018.

Other Acquisitions

On  June  12,  2019,  the  Company  acquired  Off  Campus  Partners,  LLC  ("OCP"),  a  provider  of  student  housing  marketplace  content  and  technology  to  U.S.
universities for $16 million. The purchase agreement required an initial payment of $14 million, net of cash acquired, at the time of closing, with the remainder of
the  purchase  price  payable  one  year  following  the  acquisition  date,  subject  to  offset  for  indemnification  claims  or  adjustments  to  the  purchase  price  after  final
determination  of  closing  net  working  capital.  As  part  of  the  acquisition,  the  Company  recorded  goodwill  and  intangibles  assets  of  $8 million and  $9 million,
respectively. The net assets of OCP were recorded at their estimated fair value. The estimated fair values are preliminary, subject to the Company's assessment of
certain tax matters. Measurement period adjustments recognized in 2019 were not material.

On November 8, 2018, the Company acquired Cozy Services, Ltd. ("Cozy"), a provider of online rental solutions that provides a broad spectrum of services to
both landlords and tenants, for $65 million, net of cash acquired. As part of the acquisition, the Company recorded goodwill and intangible assets of $52 million
and $11 million, respectively. The net assets of Cozy were recorded at their estimated fair value. Measurement period adjustments recognized in 2019 were not
material.

On October 12, 2018, the Company acquired Realla Ltd. ("Realla"), the operator of a commercial property listings and data management platform in the U.K.
for £12 million ($15 million). The purchase agreement required an initial payment of £10 million ($13 million), net of cash acquired, at the time of closing, with
the remainder of the purchase price paid one year following the acquisition date, subject to offset for claims under the purchase agreement. In connection with the
acquisition, the Company recorded goodwill and intangible assets of £8 million ($10 million) and £4 million ($5 million), respectively. The net assets of Realla
were recorded at their estimated fair value. Measurement period adjustments recognized in 2019 were not material.

The unrealized losses on the Company’s investments as of December 31, 2019 and 2018 were generated primarily from changes in interest rates and ARS that
failed to settle at auction, due to adverse conditions in the global credit markets. The losses are considered temporary, as the contractual terms of these investments
do  not  permit  the  issuer  to  settle  the  security  at  a  price  less  than  the  amortized  cost  of  the  investment.  Because  the  Company  does  not  intend  to  sell  these
instruments and it is not more likely than not that the Company will be required to sell these instruments prior to anticipated recovery, which may be at maturity,
the Company does not consider these investments to be other-than-temporarily impaired as of December 31, 2019 and 2018. See Note 6 for further discussion of
the fair value of the Company’s financial assets.

6.    FAIR VALUE

Fair  value  is  defined  as  the  price  that  would  be  received  in  the  sale  of  an  asset  or  paid  to  transfer  a  liability  in  an  orderly  transaction  between  market
participants. There is a three-tier fair value hierarchy, which categorizes the inputs used in measuring fair value. These tiers include: Level 1, defined as observable
inputs such as quoted prices in active markets for identical assets or liabilities; Level 2, defined as inputs other than quoted prices in active markets that are either
directly or indirectly observable; and Level 3, defined as unobservable inputs for which little or no market data exists, therefore requiring an entity to develop its
own assumptions.

The  following  table  represents  the  Company's  fair  value  hierarchy  for  its  financial  assets  (cash  equivalents  and  investments)  measured  at  fair  value  on  a

ARS  are  variable  rate  debt  instruments  whose  interest  rates  are  reset  approximately  every  28 days.  The  underlying  securities  have  contractual  maturities

greater than twenty years. The ARS are recorded at fair value.

As of December 31, 2019, the Company held ARS with $11 million par value, all of which failed to settle at auction. The majority of these investments are of
high credit quality and are primarily student loan securities supported by guarantees from the FFELP of the U.S. Department of Education. The Company may not
be able to liquidate and fully recover the carrying value of the ARS in the near term. As a result, these securities are classified as long-term investments in the
Company’s  consolidated  balance  sheet  as  of  December  31,  2019.  See  Note  5 for  further  discussion  of  the  scheduled  maturities  of  investments  classified  as
available-for-sale. 

While the Company continues to earn interest on its ARS investments at the contractual rate, these investments are not currently actively trading and therefore
do not currently have a readily determinable market value. The estimated fair value of the ARS no longer approximates par value. The Company used a discounted
cash flow model to determine the estimated fair value of its investment in ARS as of December 31, 2019. The assumptions used in preparing the discounted cash
flow model include estimates for interest rates, credit spreads, timing and amount of contractual cash flows, liquidity risk premiums, expected holding periods and
default risk. The Company updates the discounted cash flow model on a quarterly basis to reflect any changes in the assumptions used in the model and settlements
of ARS investments that occurred during the period.

The only significant unobservable input in the discounted cash flow model is the discount rate. The discount rate used represents the Company's estimate of
the  yield  expected  by  a  market  participant  from  the  ARS  investments.  The  weighted  average  discount  rate  used  in  the  discounted  cash  flow  models  as  of
December 31, 2019 and 2018 was approximately 5% and 6%, respectively. Selecting another discount rate within the range used in the discounted cash flow model
would not result in a significant change to the fair value of the ARS.

Based on this assessment of fair value, as of December 31, 2019, the Company determined there was no decline in the fair value of its ARS investments. In
addition, the ARS are of high credit quality, if the issuers are unable to successfully close future auctions and/or their credit ratings deteriorate, the Company may
be required to record additional unrealized losses in accumulated other comprehensive loss or an other-than-temporary impairment charge to earnings on these
investments.

The Company has operating leases for its office facilities, data centers and certain vehicles, as well as finance leases for office equipment. The Company's
leases have remaining terms of less than one year to  nine years. The leases contain various renewal and termination options. The period which is subject to an
option  to  extend  the  lease  is  included  in  the  lease  term  if  it  is  reasonably  certain  that  the  option  will  be  exercised.  The  period  which  is  subject  to  an  option  to

11.    LONG-TERM DEBT

On October 19, 2017, the Company entered into an amended and restated credit agreement (the ‘‘2017 Credit Agreement’’), which amended and restated in its
entirety the then-existing credit agreement dated April 1, 2014 (the "2014 Credit Agreement"). The 2017 Credit Agreement provides for a $750 million revolving
credit facility with a term of five years from a syndicate of financial institutions as lenders and issuing banks. The 2017 facility may be used for working capital
and other general corporate purposes of the Company and its subsidiaries.

Up  to  $20  million of  the  revolving  credit  facility  is  available  for  the  issuance  of  letters  of  credit.  The  Company  had  an  irrevocable  standby  letter  of
credit outstanding totaling $0.2 million as of December 31, 2019 and December 31, 2018, which was required to secure its San Francisco office lease. The letter of
credit was established in 2014 and automatically renews through January 31, 2025.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

The loans under the 2017 Credit Agreement bear interest during any interest period selected by the Company, at either (i) the London interbank offered rate
for  deposits  in  U.S.  dollars  with  a  maturity  comparable  to  such  interest  period,  adjusted  for  statutory  reserves  (“LIBOR”),  plus  an  initial  spread  of  1.25% per
annum, subject to adjustment based on the First Lien Secured Leverage Ratio (as defined in the 2017 Credit Agreement) of the Company, or (ii) at the greatest of
(x) the prime rate from time to time announced by JPMorgan Chase Bank, N.A., (y) the federal funds effective rate plus half of 1% and (z) LIBOR for a one-month
interest period plus 1.00%, plus an initial spread of 0.25% per annum, subject to adjustment based on the First Lien Secured Leverage Ratio of the Company. If an
event of default occurs under the 2017 Credit Agreement, the interest rate on overdue amounts will increase by 2.00% per annum. The obligations under the 2017
Credit Agreement are guaranteed by all material subsidiaries of the Company and are secured by a lien on substantially all of the assets of the Company and its
material subsidiaries, in each case subject to certain exceptions, pursuant to security and guarantee agreements entered into on the closing date of the 2017 Credit
Agreement. LIBOR may not always be available to the Company as a base interest rate for the credit facility, and the transition away from LIBOR is anticipated to
begin in 2021, though it may become unavailable even earlier. The Company may need or seek to negotiate with its lenders for an alternative rate. In doing so, the
Company may not be able to agree with its lenders on a replacement reference rate that was favorable as LIBOR, which may increase our capital costs.

The 2017 Credit Agreement requires the Company to maintain (i) a First Lien Secured Leverage Ratio not exceeding 3.50 to 1.00 and (ii) after the incurrence
of additional indebtedness under certain specified exceptions in the 2017 Credit Agreement, a Total Leverage Ratio (as defined in the 2017 Credit Agreement) not
exceeding 4.50 to  1.00.  The  2017  Credit  Agreement  also  includes  other  covenants,  including  ones  that  subject  to  certain  exceptions,  restrict  the  ability  of  the
Company and its subsidiaries to (i) incur additional indebtedness, (ii) create, incur, assume or permit to exist any liens, (iii) enter into mergers, consolidations or
similar transactions, (iv) make investments and acquisitions, (v) make certain dispositions of assets, (vi) make dividends, distributions and prepayments of certain
indebtedness,  and  (vii)  enter  into  certain  transactions  with  affiliates.  The  Company  was  in  compliance  with  the  covenants  in  the  2017  Credit  Agreement  as  of
December 31, 2019.

The Company had no outstanding long-term debt at December 31, 2019 and December 31, 2018. For the years ended December 31, 2019, 2018 and 2017, the
Company recognized interest expense of $3 million, $3 million and $9 million, including amortized debt issuance costs of approximately $0.9 million, $1 million
and $2 million, respectively. The Company had $2 million and $3 million of deferred debt issuance costs included in deposits and other assets at  December 31,
2019 and December 31, 2018, respectively.

As  of  December  31,  2019 and  2018,  a  valuation  allowance  has  been  established  for  certain  deferred  tax  assets  due  to  the  uncertainty  of  realization.  The
valuation allowance as of December 31, 2019 and 2018 includes an allowance for unrealized losses on ARS investments, foreign deferred tax assets and state net
operating  losses  and  tax  credits.  The  valuation  allowance  for  the  deferred  tax  asset  for  unrealized  losses  on  ARS  has  been  recorded  as  an  adjustment  to
accumulated other comprehensive loss.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

The  Company  established  the  valuation  allowance  because  it  is  more  likely  than  not  that  a  portion  of  the  deferred  tax  asset  for  certain  items  will  not  be
realized  based  on  the  weight  of  available  evidence.  A  valuation  allowance  was  established  for  the  unrealized  losses  on  securities  as  the  Company  has  not
historically  generated  capital  gains,  and  it  is  uncertain  whether  the  Company  will  generate  sufficient  capital  gains  in  the  future  to  absorb  the  capital  losses.  A
valuation allowance was established for the foreign deferred tax assets due to the cumulative loss in recent years in those jurisdictions. The Company has not had
sufficient taxable income historically to utilize the foreign deferred tax assets, and it is uncertain whether the Company will generate sufficient taxable income in
the future to utilize the deferred tax assets. Similarly, the Company has established a valuation allowance for net operating losses and tax credits in certain states
where it is uncertain whether the Company will generate sufficient taxable income to utilize the net operating losses and tax credits before they expire.

The  Company’s  change  in  valuation  allowance  was  a decrease of  approximately  $0.7 million for  the  year  ended  December  31,  2019 and  an increase of
approximately $1 million for the year ended December 31, 2018. The decrease for the year ended December 31, 2019 is due to a decrease in foreign net operating
loss deferred tax assets for which a full valuation allowance of approximately $1.1 million had been established, partially offset by an increase in the valuation
allowance  for  state  tax  credits  related  to  the  D.C.  qualified  high  technology  company  credit  of  approximately  $0.4  million.  The  increase  for  the  year  ended
December  31,  2018 is  due  to  an  increase  in  the  valuation  allowance  for  state  tax  credits  related  to  the  D.C.  qualified  high  technology  company  credit  of
approximately $1 million.

The Company had U.S. income before income taxes of approximately $403 million, $294 million and $167 million for the years ended December 31, 2019,
2018 and 2017, respectively. The Company had foreign losses before income taxes of approximately $12 million, $10 million, and $2 million for the years ended
December 31, 2019, 2018 and 2017, respectively.

Certain  of  the  Company’s  U.K.  subsidiaries  with  foreign  losses  are  disregarded  entities  for  U.S.  income  tax  purposes.  Accordingly,  the  losses  from  these
disregarded entities are included in the Company’s consolidated federal income tax provision at the statutory rate. Federal income taxes attributable to income from
these disregarded entities are reduced by foreign taxes paid by those disregarded entities.

The Company has net operating loss carryforwards for international income tax purposes of approximately $45 million, which do not expire. The Company
has federal net operating loss carryforwards of approximately $28 million that begin to expire in 2020, state net operating loss carryforwards with a tax value of

Approximately $25 million and $22 million of the unrecognized tax benefits as of December 31, 2019 and 2018, respectively, would favorably affect the
annual effective tax rate, if recognized in future periods. The increase for current year and prior year tax positions of $4 million for the year ended December 31,
2019 is primarily attributable to research credits. The decrease for expiration of the statute of limitation of  $1 million for the year ended December 31, 2019 is
primarily  attributable  to  a  state  apportionment  methodology  reserve.  The  Company  recognized  $0.2  million,  $0.2  million,  and  $0.1  million for  interest  and
penalties in its consolidated statement of operations for the years ended December 31, 2019, 2018, 2017 respectively. The Company had liabilities of $0.6 million,
$0.4 million, and $0.2 million for interest and penalties in its consolidated balance sheets as of  December 31, 2019, 2018, 2017 respectively. The Company does
not anticipate the amount of the unrecognized tax benefits will change significantly over the next twelve months.

The Company is subject to taxation in the U.S. federal jurisdiction and various states and foreign jurisdictions. The Company’s federal income tax returns for
tax years 2013 through 2018 remain open to examination. The Company is under Internal Revenue Service examination for tax year 2013 related to the research
and development credit. Most of the Company’s state income tax returns for tax years 2016 through 2018 remain open to examination. For states that have a four-
year statute of limitations, the state income tax returns for tax years 2015 through 2018 remain open to examination. The Company’s U.K. income tax returns for
tax years 2014 through 2018 remain open to examination. The Company believes that an adequate provision has been made for any adjustments that may result
from tax examinations.

13.    COMMITMENTS AND CONTINGENCIES

The  Company  leases  office  facilities  under  various  non-cancelable  operating  leases.  The  leases  contain  various  renewal  options.  See  Note  7 for  further

discussion of the Company's operating lease commitments.
.

Currently, and from time to time, the Company is involved in litigation  incidental to the conduct of its business. In accordance  with GAAP, the Company
records a provision for a liability when it is both probable that a liability has been incurred and the amount can be reasonably estimated. While it is reasonably
possible that an unfavorable outcome may occur as a result of one or more of the Company’s current litigation matters, at this time management has concluded that
the resolutions of these matters are not expected to have a material effect on the Company's consolidated financial position, future results of operations or liquidity.
Legal defense costs are expensed as incurred. During the year ended December 31, 2019, the Company received $11 million of legal settlement proceeds, which
have been included in interest and other income on the Company's consolidated statements of operations.

14.    SEGMENT REPORTING

Segment Information

F-34

 
COSTAR GROUP, INC.
NOTES TO CONSOLIDATED FINANCIAL STATEMENTS  

The  Company  manages  its  business  geographically  in  two operating  segments,  with  the  primary  areas  of  measurement  and  decision-making  being  North
America,  which  includes  the  U.S.  and  Canada,  and  International,  which  primarily  includes  Europe,  Asia-Pacific  and  Latin  America.  Management  relies  on  an
internal  management  reporting  process  that  provides  revenue  and  operating  segment  net  income  before  interest  and  other  income  (expense),  loss  on  debt
extinguishment, income taxes, depreciation and amortization (“EBITDA”). Management believes that operating segment EBITDA is an appropriate measure for
evaluating the operational performance of the Company’s operating segments. EBITDA is used by management to internally measure operating and management

The Company has 2 million shares of preferred stock, $0.01 par value, authorized for issuance as of December 31, 2019. The Board of Directors may issue the

preferred stock from time to time as shares of one or more classes or series.

Common Stock

The Company has 60 million shares of common stock,  $0.01 par value, authorized for issuance. Dividends may be declared and paid on the common stock,
subject in all cases to the rights and preferences of the holders of preferred stock and authorization by the Board of Directors. In the event of liquidation or winding
up of the Company and after the payment of all preferential amounts required to be paid to the holders of any series of preferred stock, any remaining funds shall
be distributed among the holders of the issued and outstanding common stock.

Equity Offering

In October 2017, the Company completed a public equity offering of 3.3 million shares of common stock for  $260 per share. Net proceeds from the public
equity  offering  were  approximately  $834 million,  after  deducting  approximately  $29 million of  underwriting  discounts  and  other  fees.  The  Company  used  net
proceeds from the public equity offering to fund the costs of strategic acquisitions, to finance business growth and for working capital and other general corporate
purposes.  The  Company  expects  to  use  any  remaining  net  proceeds  from  the  equity  offering  to  fund  all  or  a  portion  of  the  costs  of  any  additional  strategic
acquisitions  the  Company  determines  to  pursue,  to  finance  the  growth  of  its  business  and  for  working  capital  and  other  general  corporate  purposes.  General
corporate  purposes  may  include  additions  to  working  capital,  capital  expenditures,  repayment  of  debt,  investments  in  the  Company’s  subsidiaries,  possible
acquisitions and the repurchase, redemption or retirement of securities, including the Company’s common stock.

In  April  2007,  the  Company’s  Board  of  Directors  adopted  the  CoStar  Group,  Inc.  2007  Stock  Incentive  Plan  (as  amended,  the  “2007  Plan”),  subject  to
stockholder approval, which was obtained on June 7, 2007. In April 2016, the Company’s Board of Directors adopted the CoStar Group, Inc. 2016 Stock Incentive
Plan (as amended, the “2016 Plan”), subject to stockholder approval, which was obtained on June 9, 2016. All shares of common stock that were authorized for
issuance under the 2007 Plan that, as of June 9, 2016, remained available for issuance under the 2007 Plan (excluding shares subject to outstanding awards) were
rolled into the 2016 Plan and, as of that date, no shares of common stock were available for new awards under the 2007 Plan. The 2007 Plan continues to govern
unexercised  and  unexpired  awards  issued  under  the  2007  Plan  prior  to  June  9,  2016.  The  2007  Plan  provided  for  the  grant  of  stock  options,  restricted  stock,
restricted stock units and stock appreciation rights to officers, directors and employees of the Company and its subsidiaries. Stock options granted under the 2007
Plan could be incentive or non-qualified, and except in limited circumstances related to a merger or other acquisition, the exercise price for a stock option may not
be less than the fair market value of the Company’s common stock on the date of grant. The vesting period of the options, restricted stock and restricted stock unit
grants  under  the  2007  Plan  was  determined  by  the  Board  of  Directors  or  a  committee  thereof  and  was  generally  three  to  four years.  In  some  cases,  vesting  of
restricted stock awards under the 2007 Plan is subject to performance conditions. Upon the occurrence of a Change of Control, as defined in the 2007 Plan, all
outstanding unexercisable options and restricted stock grants under the 2007 Plan immediately become exercisable.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

The 2016 Plan provides for the grant of stock options, restricted stock, restricted stock units, and stock appreciation rights to officers, directors and employees
of the Company and its subsidiaries. Stock options granted under the 2016 Plan may be non-qualified or may qualify as incentive stock options. Except in limited
circumstances related to a merger or other acquisition, the exercise price for an option may not be less than the fair market value of the Company’s common stock
on  the  date  of  grant.  The  vesting  period  for  each  grant  of  options,  restricted  stock,  restricted  stock  units  and  stock  appreciation  rights  under  the  2016  Plan  is
determined  by  the  Board  of  Directors  or  a  committee  thereof  and  is  generally  three  to  four years,  subject  to  minimum  vesting  periods  for  restricted  stock  and
restricted stock units of at least one year. In some cases, vesting of awards under the 2016 Plan may be based on performance conditions. The Company has issued
and/or  reserved  the  following  shares  of  common  stock  for  issuance  under  the  2016  Plan:  (a)  1,450,000 shares  of  common  stock,  plus  (b)  815,464 shares  of
common stock that were authorized for issuance under the 2007 Plan that, as of June 9, 2016, remained available for issuance under the 2007 Plan (not including
any Shares that were subject as of such date to outstanding awards under the 2007 Plan), and (c) any shares of common stock subject to outstanding awards under
the 2007 Plan as of June 9, 2016, that on or after such date cease for any reason to be subject to such awards (other than by reason of exercise or settlement of the
awards to the extent they are exercised for or settled in vested and nonforfeitable shares). Unless terminated sooner, the 2016 Plan will terminate in June 2026, but
will continue to govern unexercised and unexpired awards issued under the 2016 Plan prior to that date. Approximately 2 million shares were available for future
grant under the 2016 Plan as of December 31, 2019.

At December 31, 2019, there was approximately $82 million of unrecognized compensation cost related to stock incentive plans, net of estimated forfeitures,

which the Company expects to recognize over a weighted-average-period of 2.5 years.

The aggregate intrinsic value is calculated as the difference between (i) the closing price of the common stock at the end of the period and (ii) the exercise
prices of the underlying awards, multiplied by the shares underlying options as of the end of the period that had an exercise price less than the closing price on that
date. Options to purchase 116,918, 177,299, and 81,815, shares were exercised during the years ended 2019, 2018 and 2017, respectively. The aggregate intrinsic
value  of  options  exercised,  determined  as  of  the  date  of  option  exercise,  was  approximately  $40  million,  $45  million and  $13  million for  the  years  ended
December 31, 2019, 2018 and 2017, respectively.

The weighted-average grant date fair value of each option granted during the years ended December 31, 2019, 2018 and 2017 using the Black-Scholes option-

pricing model was $115.17, $101.02 and $59.06, respectively.

The Company estimated the fair value of each option granted on the date of grant using the Black-Scholes option-pricing model, using the assumptions in the

The expected dividend yield is determined based on the Company's past cash dividend history and anticipated future cash dividend payments. The Company
has never declared or paid any dividends on its common stock and does not anticipate paying any dividends on its common stock during the foreseeable future, but
intends  to  retain  any  earnings  for  future  growth  of  its  business.  Expected  volatility  is  calculated  based  on  historical  volatility  of  the  daily  closing  price  of  the
Company's common stock over a period consistent with the expected life of the options granted. The risk-free interest rate is based on the U.S. Treasury rate with
terms similar to the expected life of the options granted. The expected life for the options is determined based on multiple factors, including historical employee
behavior patterns of exercising options and post-employment termination behavior as well as expected future employee option exercise patterns.

The Compensation Committee of the Board of Directors of the Company historically approved grants of restricted common stock to employees and directors
of the Company that vest over a specific service period and to executive officers that vest based on the achievement of certain performance conditions, primarily,
the achievement of a three-year cumulative revenue goal established at the grant date, and are subject to forfeiture in the event the foregoing performance condition
is not met by the end of each respective three-year period. These awards support the Company’s goals of aligning executive incentives with long-term stockholder
value and ensuring that executive officers have a continuing stake in the long-term success of the Company.

The vesting of restricted common stock is subject to continuing employment requirements. Certain performance-based restricted common stock awards are
also  subject  to  a  market  condition  such  that  the  actual  number  of  shares  that  vest  at  the  end  of  the  respective  three-year  period  is  determined  based  on  the
Company’s  achievement  of  performance  goals  and  an  established  Company  specific  TSR  factor  relative  to  the  Russell  1000  Index  over  the  same  three-year
performance  period.  At  the  end  of  the  three-year  performance  period,  if  the  performance  condition  is  achieved  at  or  above  the  pre-established  threshold,  the
number  of  shares  earned  is  further  adjusted  by  a  TSR  payout  percentage,  which  ranges  between  80% and  120%,  based  on  the  Company’s  TSR  performance
relative to that of the Russell 1000 Index over the respective three-year period. The Company granted a total of

36,364, 26,160, and 32,160 shares of performance-based restricted common stock during the years ended December 31, 2019, 2018 and 2017, respectively.

The Company estimates the fair value of its equity awards with both a performance and market condition on the date of grant using a Monte-Carlo simulation

valuation model. This pricing model uses multiple simulations to evaluate the probability of achieving the market condition to calculate the fair value of the
awards. Expense is only recorded for awards that are expected to vest, net of estimated forfeitures. The assumptions used to estimate the fair value of awards with
both a performance and a market condition were as follows:

The expected dividend yield is determined based on the Company's past cash dividend history and anticipated future cash dividend payments. The Company
has never declared or paid any dividends on its common stock and does not anticipate paying any dividends on its common stock during the foreseeable future, but
intends  to  retain  any  earnings  for  future  growth  of  its  business.  Expected  volatility  is  calculated  based  on  historical  volatility  of  the  daily  closing  price  of  the
common stock of the companies within the Russell 1000 Index over a period consistent with the expected life of the performance-based restricted common stock
awards  with  a  market  condition.  The  risk-free  interest  rate  is  based  on  the  U.S.  Treasury  rate  with  terms  similar  to  the  expected  life  of  the  performance-based
restricted  common  stock  awards  with  a  market  condition.  The  expected  life  is  consistent  with  the  performance  measurement  period  of  the  performance-based
restricted common stock awards with a market condition.

As of December 31, 2019, the Company determined that it was probable that the performance goals associated with restricted stock awards with performance
and market conditions granted during 2019, 2018 and 2017 would be met by their forfeiture dates. The Company recorded a total of approximately $8 million, $5
million and  $5 million of stock-based compensation expense related to restricted stock awards with a market condition for the years ended  December 31, 2019,
2018 and  2017, respectively.  As of December 31, 2019, the Company expects to record an aggregate stock-based compensation  expense of approximately  $11
million for restricted stock awards with a market condition over the periods 2020, 2021 and 2022.

The Board of Directors adopted the Company’s Management Stock Purchase Plan in December 2017 with the intent of providing selected key employees of
the Company and its subsidiaries, including the Company's executive officers, the opportunity to defer a portion of their cash incentive compensation and to align
management  and  stockholder  interests  through  awards  of  Deferred  Stock  Units  (“DSUs”)  under  the  MSPP  and  awards  of  Matching  RSUs  issued  under  the
Company 2016 Plan. Under this plan, participants are permitted to elect to defer up to 100% of their annual incentive bonus or commissions earned during the year
by submitting an irrevocable election in accordance with Section 409A of the Internal Revenue Code, as amended. On the date the incentive bonus or commission
would otherwise be paid in cash (typically during the following calendar year), the Company awards the participant DSUs representing the number of shares of
common stock with an aggregate fair market value on that date equal to the amount of compensation elected to be deferred under the MSPP. On the same date the
DSUs are awarded, the participant receives a grant of Matching RSUs covering the number of shares of common stock equal up to 100% of the DSUs granted. The
expense  related  to  the  DSUs is  recognized  on a  straight-line  basis  during  the  period  that  the  related  incentive  bonus  or  commission  is  earned.  The  stock-based
compensation  expense  for  7,441 DSUs  awarded  during  2019  was  fully  recognized  as  of  December  31,  2018.  The  expense  related  to  the  Matching  RSUs  is
recognized over the four years vesting period following the grant date.

Employee 401(k) Plan

The Company maintains a 401(k) Plan (the “401(k)”) as a defined contribution retirement plan for all eligible employees. The 401(k) provides for tax-deferred
contributions  of employees’  salaries,  limited  to a maximum  annual amount as established  by the IRS. In addition to the traditional  401(k), effective  January 1,
2015,  eligible  employees  have  the  option  of  making  an  after-tax  contribution  to  a  Roth  401(k)  plan  or  a  combination  of  both.  In  2019,  2018 and  2017,  the
Company matched 100% of employee contributions up to a maximum of 4% of total compensation. Amounts contributed to the 401(k) by the Company to match
employee contributions for the years ended December 31, 2019, 2018 and 2017 were approximately  $12 million, $12 million and $10 million, respectively. The
Company had no administrative expenses in connection with the 401(k) plan for the years ended December 31, 2019, 2018 and 2017, respectively.

Employee Pension Plan

The  Company  maintains  a  Group  Personal  Pension  Plan  (the  “Plan”)  for  all  eligible  employees  in  the  Company’s  U.K.  offices.  The  Plan  is  a  defined
contribution plan. Employees are eligible to contribute a portion of their salaries, subject to a maximum annual amount as established by Her Majesty's Revenue
and Customs. In 2019, 2018 and 2017, the Company's matching contribution was based on the percentage contributed by the employee, up to a maximum of 6% of
total compensation. Amounts contributed to the Plan by the Company to match employee contributions for the years ended December 31, 2019, 2018 and 2017,
were approximately $0.6 million, $0.5 million and $0.4 million, respectively.

Registered Retirement Savings Plan

As of January 1, 2015, the Company introduced a registered retirement savings plan (“RRSP”) for all eligible employees in the Company’s Canadian offices.
In 2017, 2016 and 2015, the Company matched 100% of employee contributions up to a maximum of 4% of total compensation. Amounts contributed to the RRSP
by the Company to match employee contributions for the years ended December 31, 2019, 2018 and 2017 were approximately $70 thousand, $58 thousand and $43
thousand, respectively.

 Employee Stock Purchase Plan

As of August 1, 2006, the Company introduced an Employee Stock Purchase Plan (“ESPP”), pursuant to which eligible employees participating in the plan
authorize  the  Company  to  withhold  specified  amounts  from  the  employees’  compensation  and  use  the  withheld  amounts  to  purchase  shares  of  the  Company's
common stock at 90% of the market price. Participating employees are able to purchase common stock under this plan during each offering period. An offering
period begins the second Saturday before each of the Company’s regular pay dates and ends on each of the Company’s regular pay dates. On June 3, 2015, the
Company’s  stockholders  approved  an  amendment  to  the  ESPP  to  increase  the  number  of  shares  available  for  purchase  under  the  ESPP  by  100,000 shares. On
September  14, 2015,  the  Company  registered  the  issuance  of  these  additional  shares  under  the  ESPP pursuant  to  the  registration  statement  filed  September  14,
2015. There were 51,584 and 65,174 shares available for purchase under the ESPP as of December 31, 2019 and 2018, respectively, and approximately 13,590 and
14,848 shares of the Company’s common stock were purchased under the ESPP during 2019 and 2018, respectively.

On February 11, 2020, CSGP Holdings, LLC (“CSGP”), an indirect wholly owned subsidiary of the Company, RentPath Holdings, Inc. (“RentPath”), certain

DESCRIPTION OF THE REGISTRANT’S SECURITIES

REGISTERED PURSUANT TO SECTION 12 OF THE

SECURITIES EXCHANGE ACT OF 1934

Exhibit 4.2

CoStar Group, Inc. (“CoStar,” “we,” “us” or “our”) has one class of securities registered under Section 12 of the Securities Exchange
Act of 1934, as amended (the “Exchange Act”): our Common Stock, par value $0.01 per share (our “common stock”).

DESCRIPTION OF COMMON STOCK

The following summary description sets forth some of the general terms and provisions of our common stock. Because this is a
summary description, it does not contain all of the information that may be important to you. For a more detailed description of our
common stock, you should refer to the provisions of our third amended and restated certificate of incorporation(our “Certificate of
Incorporation”) and our third amended and restated By-laws (our “By-laws”), each of which are filed as exhibits to the Annual
Report on Form 10-K to which this description is an exhibit.

General

Under our Certificate of Incorporation, we are authorized to issue up to sixty million (60,000,000) shares of our common stock and
two million (2,000,000) shares of preferred stock, par value $.01 per share (our “preferred stock”). The shares of our common stock
currently outstanding are fully paid and non-assessable. No shares of preferred stock are currently outstanding.

Voting Rights

Holders of shares of common stock have one vote per share in all elections of directors and on all other matters submitted to a vote
of stockholders of CoStar. Except as otherwise required by law, our Certificate of Incorporation or our By-laws, matters submitted to
a vote of stockholders (other than director elections) will be decided by the affirmative vote of a majority of the shares of our
common stock present or represented by proxy and entitled to vote on the matter. Holders of shares of our common stock do not
have cumulative voting rights.

Directors will be elected if the number of votes properly cast “for” a nominee’s election exceeds the number of votes properly cast
“against” such nominee’s election, unless the number of nominees exceeds the number of directors to be elected, in which case the
directors shall be elected by the vote of a plurality of the votes cast. There is no provision for cumulative voting with regard to the
election of directors.

Dividend Rights

Subject to the preferences applicable to any then-outstanding shares of preferred stock, the holders of common stock are entitled to
receive dividends, if any, as and when declared, from time to time, by our board of directors out of funds legally available therefor.

Liquidation, Dissolution or Similar Rights

Upon dissolution, after satisfaction of the claims of creditors and the payment to any holders of preferred stock of the full
preferential amounts to which such holders may be entitled, the remaining assets of CoStar would be distributed to the holders of the
common stock ratably in proportion to the number of shares of common stock held by them.

Other Rights

Our common stock is not redeemable, is not subject to redemption or sinking fund provisions, does not have any conversion rights
and is not subject to call. Holders of shares of common stock do not have preemptive rights to acquire newly issued shares.

Anti-Takeover Effects of Provisions of our Certificate of Incorporation, Bylaws, and Delaware Law

Various provisions contained in our Certificate of Incorporation, our By-laws, and Delaware law could delay or discourage some
transactions involving an actual or potential change in control of CoStar or its management.

For example, provisions in our Certificate of Incorporation and our By-laws:
•

authorize our board of directors to establish one or more series of undesignated preferred stock, the terms of which can be
determined by our board of directors at the time of issuance;
do not authorize cumulative voting;
authorize our board of directors to alter, amend or repeal any bylaw;
provide that, except as otherwise provided in our Certificate of Incorporation or by Delaware law, special meetings of our
stockholders may be called only by our board of directors in a resolution approved by a majority of the board of directors or by
the Chairman of our board of directors or the President of CoStar;
provide that our stockholders may take action only at a duly called meeting and not by written consent;
in connection with stockholder meetings, provide an advanced written notice procedure with respect to stockholder nominations
for directors and bringing other business; and
provide that our directors may fill any vacancies on our board of directors, including newly created board seats resulting from an
increase in the authorized number of directors and vacancies resulting from death, resignation, or other cause.

•
•
•

•
•

•

In addition, we are subject to Section 203 of the Delaware General Corporation Law, which regulates, subject to some exceptions,
acquisitions of publicly held Delaware corporations. In general, Section 203 prohibits us from engaging in a “business combination”
with an “interested

stockholder” for a period of three years following the date the person becomes an interested stockholder, unless:

•

•

•

our board of directors approved the business combination or the transaction in which the person became an interested
stockholder prior to the date the person attained this status;
upon consummation of the transaction that resulted in the person becoming an interested stockholder, the person owned at least
85% of our voting stock outstanding at the time the transaction commenced, excluding shares owned by persons who are
directors and also officers and issued under employee stock plans under which employee participants do not have the right to
determine confidentially whether shares held subject to the plan will be tendered in a tender or exchange offer; or
on or subsequent to the date the person became an interested stockholder, our board of directors approved the business
combination and the stockholders other than the interested stockholder authorized the transaction at an annual or special meeting
of stockholders by the affirmative vote of at least two-thirds of the outstanding stock not owned by the interested stockholder.

Section 203 defines a “business combination” to include:

•
•
•
•

•

any merger or consolidation involving us and the interested stockholder;
any sale, transfer, pledge or other disposition involving the interested stockholder of 10% or more of our assets;
in general, any transaction that results in the issuance or transfer by us of any of our stock to the interested stockholder;
any transaction involving us that has the effect of increasing the proportionate share of our stock owned by the interested
stockholders; and
the receipt by the interested stockholder of the benefit of any loans, advances, guarantees, pledges, or other financial benefits
provided by or through us.

In general, Section 203 defines an “interested stockholder” as any person who, together with the person’s affiliates and associates,
owns, or within three years prior to the time of determination of interested stockholder status did own, 15% or more of a
corporation’s voting stock.
