NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS (unaudited)

1.ORGANIZATION

CoStar Group, Inc. (the “Company” or “CoStar”) provides information, analytics, online marketplace and auction services to the commercial real estate and related business community through its comprehensive, proprietary database of commercial real estate information and related tools. 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.

2.SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

Basis of Presentation

The condensed 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.

Interim Financial Statements

The accompanying unaudited condensed consolidated financial statements of the Company have been prepared in accordance with U.S. generally accepted accounting principles (“GAAP”) for interim financial information. In the opinion of the Company’s management, the financial statements reflect all adjustments, consisting only of a normal recurring nature, necessary to present fairly the Company’s financial position at September 30, 2020 and December 31, 2019, the results of its operations for the three and nine months ended September 30, 2020 and 2019, its comprehensive income for the three and nine months ended September 30, 2020 and 2019, its changes in stockholders' equity for the three and nine months ended September 30, 2020 and 2019, and its cash flows for the nine months ended September 30, 2020 and 2019.

Certain notes and other information have been condensed or omitted from the interim financial statements presented in this Quarterly Report on Form 10-Q. Therefore, these financial statements should be read in conjunction with the Company’s Annual Report on Form 10-K for the year ended December 31, 2019.

Use of Estimates

The preparation of financial statements in conformity with 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 credit losses, the useful lives and recoverability of long-lived and intangible assets, and goodwill, income taxes, 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

COSTAR GROUP, INC.

NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS (unaudited)

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 (i) market research, portfolio and debt analysis, management and reporting capabilities, (ii) real estate and lease management solutions, including lease administration and abstraction services, to commercial customers, real estate investors, and lenders via the Company’s other service offerings, (iii) benchmarking and analytics for the hospitality industry through STR, LLC and STR Global, Ltd. (together with STR, LLC, referred to as “STR”) and (iv) an online auction platform for commercial real estate through Ten-X, LLC and its subsidiaries which were acquired in June 2020. See Note 5 for details of the acquisition.

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).

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 as those obligations are satisfied.

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.

Cost of Revenues

Cost of revenues principally consists of salaries, benefits, bonuses and stock-based compensation expenses and other indirect costs 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 and for employees that support these products. 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, and the amortization of acquired trade names, technology and other intangible assets.

Advertising Costs

The Company expenses advertising costs as incurred. Advertising costs include digital marketing, television, company-sponsored events, print and other media advertising. Advertising costs were approximately $79 million and $44 million for the three months ended September 30, 2020 and 2019, respectively, and $202 million and $130 million for the nine months ended September 30, 2020 and 2019, respectively.

Foreign Currency

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. Gains and losses resulting from transactions denominated in a currency other than the functional currency of the entity are included in other (expense) income in the condensed consolidated statements of operations using the average exchange rates in effect during the period. The Company recognized net foreign currency losses of $0.2 million and gains of $0.2 million for the three months ended September 30, 2020 and 2019, respectively, and net foreign currency gains of $0.7 million and $0.2 million for the nine months ended September 30, 2020 and 2019, respectively, which are included in other (expense) income on the condensed consolidated statements of operations.

During the nine months ended September 30, 2020, the Company sold its long-term variable debt instruments with an auction reset feature, referred to as auction rate securities ("ARS") and reclassified out of accumulated other comprehensive loss a realized loss of $0.5 million to earnings which is included in other (expense) income in the condensed consolidated statements of operations. There were no amounts reclassified out of accumulated other comprehensive loss to the condensed consolidated statements of operations for the three and nine months ended September 30, 2019.

See Note 6 for additional information regarding investments.

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 condensed 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.

See Note 11 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 Company’s potentially dilutive securities include outstanding stock options and unvested stock-based awards which include restricted stock awards that vest over a specific service period, restricted stock awards with a performance and a market condition, restricted stock units and awards of matching restricted stock units ("Matching RSUs") awarded under the Company's Management Stock Purchase Plan. Shares underlying unvested restricted stock 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 net income 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.

The following table summarizes the shares underlying the unvested performance-based restricted stock and anti-dilutive securities excluded from the basic and diluted earnings per share calculations (in thousands):

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.

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.

Allowance for Credit Losses

On January 1, 2020, the Company adopted Accounting Standards Updates ("ASU") 2016-13, Financial Instruments - Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments; ASU 2018-19, Codification Improvements to Topic 326, Financial Instruments - Credit Losses; ASU 2019-04, Codification Improvements to Financial Instruments - Credit Losses (Topic 326); ASU 2019-05, Financial Instruments - Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instrument; ASU 2019-11, Codification Improvements to Financial Instruments - Credit Losses (Topic 326) and ASU 2020-02, Financial Instruments-Credit Losses (Topic 326) and Leases (Topic 842), later codified as Accounting Standards Codification ("ASC") 326 ("ASC 326"), using the modified retrospective transition approach. Refer to the Company’s Annual Report on Form 10-K for the year ended December 31, 2019, filed with the Securities and Exchange Commission on February 26, 2020, for further details of the Company’s policy prior to the adoption of ASC 326.

As of January 1, 2020, the Company maintained an allowance for credit losses to cover its current expected credit losses ("CECL") on its trade receivables and contract assets arising from the failure of customers to make contractual payments. The Company estimates credit losses expected over the life of its trade receivables and contract assets based on historical information combined with current conditions that may affect a customer’s ability to pay and reasonable and supportable forecasts. While the Company uses various credit quality metrics, it primarily monitors collectability by reviewing the duration of collection pursuits on its delinquent trade receivables. Based on the Company’s experience, the customer's delinquency status is the strongest indicator of the credit quality of the underlying trade receivables, which is analyzed monthly. In most instances, the Company’s policy is to write-off trade receivables when they are deemed uncollectible. A majority of the Company's trade receivables are less than 365 days outstanding.

Under the CECL impairment model, the Company develops and documents its allowance for credit losses on its trade receivables based on four portfolio segments. The determination of portfolio segments is based primarily on the qualitative consideration of the nature of the Company’s business operations and the characteristics of the underlying trade receivables, as follows:

•CoStar Suite Portfolio Segment - The CoStar Suite portfolio segment consists of two classes of trade receivables based on geographical location: CoStar Suite, North America and CoStar Suite, International.

•Information Services Portfolio Segment - The information services portfolio segment consists of four classes of trade receivables: Real Estate Manager; information services, North America; STR, US; and STR, International.

•Multifamily Portfolio Segment - The multifamily portfolio segment consists of one class of trade receivables.

•Commercial Property and Land Portfolio Segment - The commercial property and land portfolio segment consists of two classes of trade receivables: LoopNet; and other commercial property and land online marketplaces.

See Note 4 for further discussion of the Company’s accounting for allowance for credit losses.

Leases

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 deemed 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, offset by lease incentives. The ROU asset also includes any lease prepayments. 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 and 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.

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.

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 the 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 undiscounted 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.

Goodwill is tested annually for impairment by each reporting unit on October 1 of each year or more frequently if an event or other circumstance indicates that we may not recover the carrying value of the asset. The Company 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 the Company elects to bypass such assessment, the Company then determines the fair value of each reporting unit. 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. The Company made a policy election to classify deferred issuance costs on the revolving credit facility as a long-term asset on its condensed consolidated balance sheets. 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 10 for additional information regarding the Company's 2020 Credit Agreement and Senior Notes issuance.

Business Combinations

The Company allocates the purchase consideration related to business combinations to the identifiable tangible and intangible assets acquired, and liabilities assumed based on their estimated fair values. The purchase consideration 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 and other intangible assets, 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, determine their estimated fair value.

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 condensed consolidated statements of operations and comprehensive income and could have a material impact on its results of operations and financial position.

On June 24, 2020, pursuant to the Agreement and Plan of Merger, dated May 13, 2020, by and among CoStar Realty Information, Inc., a Delaware corporation and wholly owned subsidiary of the Company (“CRI”), Crescendo Sub, Inc., a Delaware corporation and wholly-owned subsidiary of CRI (“Merger Sub”), Ten-X Holding Company, Inc., a Delaware corporation ("Ten-X Holding"), and Thomas H. Lee Equity Fund VII L.P., a Delaware limited partnership, solely in its capacity as representative thereunder, Merger Sub was merged with and into Ten-X Holding (the “Merger”), with Ten-X Holding surviving the Merger as a wholly-owned subsidiary of CRI. In connection with the Merger, the Company acquired all of the issued and outstanding equity interests in Ten-X Holding and Ten-X Holding's subsidiaries (collectively, "Ten-X") for a purchase price of $187 million in cash. Ten-X operates an online auction platform for commercial real estate. The Ten-X acquisition is expected to enable the Company to create a new end-to-end commercial real estate platform, combining LoopNet and our online audience of buyers with Ten-X’s leadership in online auctions for performing and distressed assets.

Deferred tax liabilities	(4,810)
Other assets and liabilities	(4,697)
Fair value of identifiable net assets acquired	$	187,360

The net assets of Ten-X 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 estimated fair value of 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 attrition rates and profit margins.

The following table summarizes the fair values (in thousands) of the identifiable intangible assets included in the Company's North America operating segment, their related estimated useful lives (in years) and their respective amortization methods:

Goodwill recorded in connection with this acquisition is not amortized, but is subject to an annual impairment test. Goodwill recognized is not deductible for income tax purposes.

As of September 30, 2020, transaction costs associated with the Ten-X acquisition were not material. The Company paid $3 million in incentive compensation to Ten-X employees negotiated as part of the acquisition, the expense was recognized in the post-combination period.

RentPath

On February 11, 2020, RentPath Holdings, Inc. (“RentPath”), certain direct or indirect wholly-owned subsidiaries of RentPath (together with RentPath, the “Sellers”), and, solely for the purposes set forth therein, CSGP Holdings, LLC (“CSGP”), an indirect wholly owned subsidiary of the Company ("Buyer") entered into an asset purchase agreement (the “Asset Purchase Agreement”) dated as of February 12, 2020. Pursuant to the Asset Purchase Agreement, and subject to the terms and conditions set forth therein, CSGP agreed to acquire for $588 million in cash all of the equity interests of RentPath, as reorganized following an internal restructuring of the Sellers (“Reorganized RentPath") pursuant to and under the joint chapter 11 plan of reorganization of the Sellers and certain of their affiliates to be filed in the U.S. Bankruptcy Court for the District of Delaware. Under the terms of the Asset Purchase Agreement, the Company agreed to guarantee the full and timely performance of CSGP’s obligations under the Asset Purchase Agreement. The completion of the transaction is subject to customary conditions, including the expiration or termination of the applicable waiting period under applicable antitrust laws and bankruptcy approvals. On April 29, 2020, the Company and RentPath each received a request for additional information from the U.S. Federal Trade Commission (“FTC”) with respect to the acquisition. The FTC’s additional request extends the waiting period imposed by the Hart-Scott Rodino Antitrust Improvements Act of 1976 (the “HSR Act”) until the parties complete the compliance process and the FTC completes its review of the substance of the parties' submission. Bankruptcy court approval was obtained on June 9, 2020. On July 29, 2020, the Company exercised its option pursuant to the Asset Purchase Agreement to extend the date after which either the Sellers or the Buyer may terminate the Asset Purchase Agreement if the transaction has not closed (the “Outside Date”) for an additional three months until November 12, 2020 in exchange for payment of $7.5 million. As required by the Asset Purchase Agreement, the Company paid a $59 million break fee into a cash escrow account. In the event the Asset Purchase Agreement is terminated under specified circumstances and either certain antitrust approvals are not obtained or a governmental order related to antitrust or competition matters prohibits the consummation of the transaction, this amount is not refundable to the Company. As the transaction had not closed as of September 30, 2020, the break fee is recorded as restricted cash within cash, cash equivalents and restricted cash on the Company's condensed consolidated balance sheets.

STR, LLC 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 $436 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.

Deferred tax liabilities	(7,980)
Other assets and liabilities	(4,815)
Fair value of identifiable net assets acquired	$	435,794

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. Measurement period adjustments primarily relate to the determination of working capital as of the acquisition date. 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 attrition rates and projected profit margins. The following table summarizes the fair values (in thousands) of the identifiable intangible assets included in each of the Company's operating segments, their related estimated useful lives (in years) and their respective amortization methods:


	North America			International
	Estimated Fair Value		Estimated Useful Life	Estimated Fair Value		Estimated Useful Life	Amortization Method
Customer base	$	97,000	13	$	42,000	10	Accelerated
Trade name	24,000		15	—			Straight-line
Other intangible assets	10,000		5	5,000		5	Straight-line
Total intangible assets	$	131,000		$	47,000

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 $262 million of goodwill recorded as part of the acquisition, $159 million and $103 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 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 if and when the employment of such employees is earlier terminated by the Company without cause or by the employee 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.

Off Campus Partners, LLC Acquisition

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. During the three months ended June 30, 2020, the Company paid the remaining purchase price in full. 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. Measurement period adjustments recognized in 2019 were not material.

6.INVESTMENTS AND FAIR VALUE MEASUREMENTS

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.

As of September 30, 2020, the Company's financial assets comprise Level 1 cash equivalents with original maturities of three months or less in the amount of $3,512 million. As of September 30, 2020, the Company had no Level 2 or Level 3 financial assets measured at fair value.

During the nine months ended September 30, 2020, the Company sold its ARS investments for $10.3 million and recognized a realized loss of $0.5 million for the nine months ended September 30, 2020 included in other (expense) income on the Company's condensed consolidated statements of operations.

The Company’s Level 3 assets consisted of ARS; whose underlying assets were primarily student loan securities supported by guarantees from the Federal Family Education Loan Program of the U.S. Department of Education. As of December 31, 2019, these investments were in an unrealized loss position for a period of twelve months or greater. The unrealized losses 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 were 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. The Company had no realized gains or losses on its investments during the year ended December 31, 2019.

In addition to the financial instruments listed above, the Company holds other financial instruments, including cash equivalents, cash deposits, accounts receivable, accounts payable, accrued expenses and senior notes. The carrying value for such financial instruments, other than the senior notes, each approximated their fair values as of September 30, 2020 and December 31, 2019. The estimated fair value of the Company's outstanding senior notes using quoted prices from the over-the-counter markets, considered Level 2 inputs, was $1.03 billion as of September 30, 2020.

Senior Notes

On July 1, 2020, the Company issued $1.0 billion aggregate principal amount of 2.800% Senior Notes due July 15, 2030 (the “Senior Notes”). The Senior Notes were sold to a group of financial institutions as initial purchasers who subsequently resold the Senior Notes to non-U.S. persons pursuant to Regulation S under the Securities Act of 1933, as amended (the “Securities Act”), and to persons reasonably believed to be qualified institutional buyers pursuant to Rule 144A under the Securities Act at a purchase price equal to 99.921% of their principal amount. Interest on the Senior Notes is payable semi-annually in arrears beginning on January 15, 2021. The Senior Notes may be redeemed in whole or in part by the Company (a) at any time prior to April 15, 2030 at a redemption price equal to 100% of the principal amount of the Senior Notes, plus the Applicable Premium (as calculated in accordance with the indenture governing the Senior Notes) as of, and any accrued and unpaid interest, if any, on the principal amount of Senior Notes being redeemed to, but excluding, the redemption date, and (b) on or after April 15, 2030 at a redemption price equal to 100% of the principal amount of the Senior Notes, plus any accrued and unpaid interest, if any, on the principal amount of Senior Notes being redeemed to, but excluding, the redemption date. The Company’s obligations under the Senior Notes are guaranteed on a senior, unsecured basis by the Company’s domestic wholly owned subsidiaries.

In connection with the issuance of the Senior Notes, the Company incurred approximately $13 million in debt issuance costs.

Revolving Credit Facility

On July 1, 2020, the Company also entered into a second amended and restated credit agreement (the "2020 Credit Agreement"), which amended and restated in its entirety the then-existing credit agreement originally entered into in April 1, 2014 and amended and restated on October 19, 2017 (the “2017 Credit Agreement”). The 2020 Credit Agreement provides for a $750 million revolving credit facility with a term of five years (maturing July 1, 2025) and a letter of credit sublimit of $20 million from a syndicate of financial institutions as lenders and issuing banks. On July 1, 2020, the Company repaid in full the balance on its existing $750 million revolving credit facility under the 2017 Credit Agreement using the proceeds from the issuance of the Senior Notes. A commitment fee of 0.25% to 0.30% per annum, depending on the Total Leverage Ratio (defined in 2020 Credit Agreement), is payable quarterly in arrears based on the unused revolving commitment.

Subject to certain conditions, on no more than five occasions, the Company may request increases in the amount of revolving commitments and/or the establishment of term commitments under the 2020 Credit Agreement. Borrowings under the 2020 Credit Agreement will bear interest at a floating rate which can be, at the Company’s option, either (a) an alternate base rate plus an applicable rate ranging from 0.50% to 1.25% or (b) a LIBOR or EURIBOR (with a floor of 0.00%) for the specified interest period plus an applicable rate ranging from 1.50% to 2.25%, in each case depending on the Company's Total Leverage Ratio (as defined in the 2020 Credit Agreement). LIBOR may not always be available to the Company as a base interest rate for borrowings under the credit facility. Funds drawn down on the revolving credit facility pursuant to the 2020 Credit Agreement may be used for working capital and other general corporate purposes of the Company and its restricted subsidiaries. The obligations under the 2020 Credit Agreement are guaranteed by each of the Company’s current and future direct or indirect wholly owned restricted domestic subsidiaries, other than certain excluded subsidiaries, in each case subject to certain exceptions, pursuant to guarantee agreements.

The 2020 Credit Agreement includes covenants, including ones that, subject to certain exceptions, restrict the ability of the Company and its subsidiaries to (i) merge and consolidate with other companies, (ii) incur indebtedness, (iii) grant liens or security interests on assets, (iv) make investments, acquisitions, loans or advances, (v) pay dividends and (vi) sell or otherwise transfer assets. During any period of time that the Company has obtained and maintained a corporate investment grade rating from at least two designated rating agencies and no Event of Default is continuing, the Company is not subject to certain covenants such as restrictions on the ability to incur indebtedness (such period, a “Covenant Suspension Period”). As of September 30, 2020, the Company is in a Covenant Suspension Period. The 2020 Credit Agreement also requires the Company to maintain a Total Leverage Ratio (as defined in the 2020 Credit Agreement) not exceeding 4.50 to 1.00. The Company was in compliance with the covenants in the 2020 Credit Agreement as of September 30, 2020.

In connection with the 2020 Credit Agreement, the Company incurred approximately $3.6 million in debt issuance costs. As of September 30, 2020, the Company had not drawn any amounts under this facility.

The Company had an irrevocable standby letter of credit outstanding totaling $0.2 million as of September 30, 2020 and December 31, 2019, which is required to secure its San Francisco office lease. The letter of credit was established in 2014 and automatically renews annually through January 31, 2025.

For the three and nine months ended September 30, 2020 and 2019, the Company recognized interest expense as follows (in thousands):

11.INCOME TAXES

The income tax provision reflects an effective tax rate of approximately 16% and 21% for the three months ended September 30, 2020 and 2019, respectively, and 15% and 18% for the nine months ended September 30, 2020 and 2019, respectively. The decrease in the effective tax rate for the three and nine months ended September 30, 2020 was primarily due to lower income before income taxes for the three and nine months ended September 30, 2020, as well as an increase in excess tax benefits.

On March 27, 2020, President Trump signed into law the Coronavirus Aid, Relief and Economic Security Act (the "CARES Act"). The CARES Act did not have a material impact on the Company's condensed consolidated financial statements for the nine months ended September 30, 2020.

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.

13.SEGMENT REPORTING

Segment Information

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 expense (income) and other expense (income), 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 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.

(the “Company” or “CoStar”) 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 June 24, 2020, we acquired Ten-X Holding Company, Inc. and its subsidiaries ("Ten-X"), which operate an online auction platform for commercial real estate. See Note 5 to the accompanying Notes to the Condensed Consolidated Financial Statements included in Part I of this Quarterly Report on Form 10-Q for further discussion of this acquisition.

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. 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 period-to-period and year-to-year and our revenue is not generally seasonal because our services are typically sold on a subscription basis.

Our primary brands include CoStar, LoopNet, Apartments.com, STR, Ten-X, BizBuySell and LandsofAmerica. We also provide other services that complement those offered through our primary brands. These include real estate and lease management solutions, lease administration and abstraction services through our CoStar Real Estate Manager service offerings; and 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. Our principal service offerings are discussed in more detail below.

Impact of the COVID-19 Pandemic

A novel strain of coronavirus known as "COVID-19" was first identified in Wuhan, China in December 2019, and was subsequently declared a pandemic by the World Health Organization on March 11, 2020. COVID-19 has surfaced in nearly all regions around the world and resulted in travel restrictions and business slowdowns or shutdowns in affected areas. The full impact of the COVID-19 pandemic is unknown and is evolving as the pandemic continues. The COVID-19 pandemic did not materially affect the Company's condensed consolidated financial statements for the three and nine months ended September 30, 2020.

We are closely and continually monitoring the impact of the COVID-19 pandemic on our business, employees, customers, and communities. To protect the health and safety of our employees and to help stop the spread of the disease, we shifted to a digital, remote workplace in mid-March 2020. As of that time, nearly all of our employees began to work from home and continue to do so as of the date of this filing. We have temporarily shifted certain employees’ job responsibilities so they can work from home and modified our in-person research and sales processes so that they can be conducted safely and in compliance with social distancing guidelines to protect our employees, our customers and our communities. We believe our employees are operating at near normal levels of productivity in this digital environment. We continue to monitor events related to the pandemic, as well as the guidelines and mandates provided by governmental and health authorities. We plan to continue adapting our business operations when and as deemed appropriate to comply with these guidelines and mandates and to respond to changing circumstances.

In connection with the shift to work from home, we incurred and may continue to incur expenses to help employees perform their jobs effectively and securely. In preparation for an eventual return to work in the office, we have also incurred and expect to continue to incur expenses to help protect the health and safety of our employees and visitors. In response to the COVID-19 pandemic, we had taken steps to manage our costs, including minimizing hiring to essential positions, restricting business travel and canceling in-person marketing events. We expect to continue to minimize travel and restrict in-person marketing events during the remainder of the year. Overall, the increased direct spend related to COVID-19 has not been material to date and has had minimal impact as these expenses have been generally offset by the cost savings of COVID-19 operational changes. As the situation evolves, we may implement additional cost reductions.

Current general economic conditions in the U.S. and the world as a result of the COVID-19 pandemic are negatively affecting business operations for our clients and are expected to result in business consolidations and, in certain circumstances, failures. In general, customers are seeking to reduce expenses as a result of current economic conditions. The extent and duration of any future continued weakening of the global economy is unknown. There can be no assurance that any of the governmental or private sector initiatives designed to strengthen the U.S. and other economies will ultimately be successful or available to us and our customers, and, if successful, when the benefits will be available or seen. Because of the rapidly evolving nature of the COVID-19 pandemic and responses to it by, and the impact on, global economies, our revenue or earnings forecasts may not prove to be accurate. Any expected changes in financial results discussed in this report, including any expected impact of COVID-19, are based on our current observations and experience and involve estimates and assumptions. As the extent and duration of the impacts from COVID-19 remain unclear, the Company's estimates and assumptions may evolve as conditions change. Our current observations and past experience and results may not be an indicator of ongoing trends or future results, and actual results could differ significantly from our estimates and expectations.

Our near-term revenues are relatively predictable as a result of our subscription-based business model; however, we expect that we will continue to experience the effects of the COVID-19 pandemic on our business, results of operations and overall financial performance. Such effects may include, among others, a decrease in new customer sales and increases in customer cancellations, suspensions, service reductions and failures to pay or delays in payments of amounts owed to us. We are more likely to incur asset impairment charges or restructuring charges, or further increase our allowance for credit losses, as a result of this crisis and related economic downturn, which could adversely affect our results of operations. The amount and frequency of such actions will be affected by the severity and duration of the COVID-19 pandemic. We experienced an increase in customer requests for cancellations and suspensions towards the end of the first quarter of 2020 that continued through May 2020; however, those requests have eased since then, and sales related to marketplace service offerings have returned to pre-pandemic levels. During the first three quarters of 2020, we increased the allowance for credit loss as a result of increased write-off trends and increased the forecasted credit loss estimate on high credit risk customers to reflect the uncertainty around the duration and speed of an economic recovery. Due to the uncertainty associated with the COVID-19 pandemic, we will continue to monitor customer behavior and its impact on our results of operations. See Note 4 to the accompanying Notes to the Condensed Consolidated Financial Statements included in Part I of this Quarterly Report on Form 10-Q and the "Comparison of Three Months Ended September 30, 2020 and Three Months Ended September 30, 2019" below for further discussion.

We strengthened our liquidity position through an equity offering of common stock in May 2020 and an offering of Senior Notes and amendment and restatement of our credit facility in early July 2020. See Note 10 and Note 14 to the accompanying Notes to the Condensed Consolidated Financial Statements included in Part I of this Quarterly Report on Form 10-Q and the “Development, Investments and Expansion” below for further discussion of our recent equity and Senior Notes offerings and the 2020 Credit Agreement. Overall, the effects of the pandemic have not affected our ability to date to access funding on reasonably similar terms as were available prior to March 2020. We discuss the current and potential impact of select provisions of the CARES Act (defined below) in our liquidity discussion.

Service Offerings

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 online and 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 commercial real estate sales force is currently responsible for selling multiple product lines, including CoStar Suite and LoopNet. Sales initiatives commenced in late 2019 shifted the focus of our sales force to sales of LoopNet Signature Ads, a premium listing service. As a result of this shift, as well as the continued impact of COVID-19 on our current and potential customer base, we have seen a decline in CoStar revenue growth rates in 2020 and currently anticipate CoStar Suite revenue growth rates to continue to decline through the remainder of the year. In the coming months, we plan to separate the CoStar and LoopNet sales teams and build out a dedicated LoopNet sales force.

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 that became effective for public companies for financial reporting periods beginning after December 15, 2018. CoStar Real Estate Manager continued to experience high revenue growth rates for most of 2019. In the first half of 2020, growth rates began to decline as the surge of the demand eased as companies passed the implementation date for the new requirements and customer behavior began to change in response to economic conditions, including delays in implementation of new services resulting in a reduction of implementation fees. During the third quarter of 2020, we experienced moderate increases in revenue growth rates compared to the second quarter of 2020 due to additional professional fees.

On October 22, 2019, we acquired STR and we now also provide STR’s complementary benchmarking and analytics services to the hospitality industry. Sales of STR's services also represent a significant portion of our information services revenue. STR sells the majority of its services on a subscription basis, but also has one-time or ad hoc transaction fee revenues. The hospitality industry has been severely impacted by COVID-19. As a result, revenue for STR declined in the second quarter as compared to the first quarter. However, we saw a moderate increase in revenue in the third quarter of 2020 as compared to the second quarter of 2020. During the first three quarters of 2020, we provided payment extensions to certain STR customers and in the third quarter of 2020, we saw slight improvements in collections as hotels reopened. We will continue to monitor customer behavior and any resulting impact to our financial condition and results of operations. See Note 5 to the accompanying Notes to the Condensed Consolidated Financial Statements included in Part I of this Quarterly Report on Form 10-Q for further discussion of this acquisition.

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 network of subscription-based advertising services provides property management companies and landlords with a comprehensive advertising destination for their available rental units and offers renters a platform for searching for available rentals. In the third quarter of 2020, multifamily revenue growth rates continued to increase relative to 2019 revenue growth rates as tenants, property owners and landlords continued to transact in our digital environment. See Note 5 to the accompanying Notes to the Condensed Consolidated Financial Statements included in Part I of this Quarterly Report on Form 10-Q for further discussion of the OCP acquisition.

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. Loopnet.com represents a majority of the commercial property and land revenue. As part of our rebuild and launch of the LoopNet Signature Ads product, we rolled out new ad packages in the fourth quarter of 2019 and shifted the focus of our commercial real estate sales force to LoopNet Signature Ads. As a result, the LoopNet revenue growth rate increased in the fourth quarter of 2019 and in the first quarter of 2020. As a result of COVID-19 and its impact on the commercial real estate industry, LoopNet.com sales volumes declined and cancellations increased in the second quarter of 2020. In the third quarter of 2020, we saw a significant increase in sales and a decline in cancellations. Overall, revenues in commercial property and land increased compared to the third quarter of 2019 primarily due to revenue from our newly acquired online auction platform, Ten-X and, to a lesser extent, revenue growth from LoopNet. Accordingly, we expect the revenue growth rates will continue to increase for the reminder of the year relative to 2019 growth rates. Our BizBuySell network, which includes BizQuest® and FindaFranchise, and our Land.com network of sites, which includes LandsofAmerica, LandAndFarm and LandWatch®, are also included in our commercial property and land service revenue. The BizBuySell network provides online marketplaces for businesses for-sale and our Land.com network of sites provide online marketplaces for rural lands for-sale.

As of September 30, 2020 and 2019, our net bookings of subscription-based services on all contracts were approximately $53 million and $50 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. The factors resulting in this year-over-year change are discussed above. 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 nine months ended September 30, 2020 and 2019, our contract renewal rates for existing CoStar subscription-based services on annual contracts were approximately 89% and 90%, respectively, and therefore our cancellation rate for those services for the same periods were approximately 11% and 10%, respectively. Our contract renewal rate is a quantitative measurement that is typically closely correlated with our revenue results. As a result, management believes that the rate may be a reliable indicator of short-term and long-term performance absent extraordinary circumstances. Our trailing twelve-month contract renewal rate may decline in light of COVID-19 developments and the resulting negative economic conditions leading 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 plan to continue to invest in our business and our services, evaluate strategic growth opportunities, and pursue our key priorities as described below, while we closely monitor the economic developments from the COVID-19 pandemic and manage our response to such developments. We are committed to supporting, improving and enhancing our information, analytics and online marketplace solutions, including expanding and improving our offerings for our client base and site users, including property owners, property managers, buyers, tenants and renters. We expect to continue our software development efforts to improve existing services, introduce new services, integrate and cross-sell services, integrate recently completed acquisitions and expand and develop supporting technologies for our research, sales and marketing organizations. We may reevaluate our priorities as the COVID-19 pandemic continues to evolve.

Our key priorities for the remainder of 2020 currently include:

•Integrating recently completed acquisitions, including STR and Ten-X, with our business operations. We are consolidating STR data and services with CoStar Suite to create an integrated platform. We expect that the combination of STR's and CoStar's offerings will allow us to create valuable new and improved tools for industry participants. 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 we serve. We also recently acquired Emporis, a Germany-based provider of international commercial real estate data and images that we plan to integrate into CoStar. We are working on integrating the Ten-X platform into both LoopNet and CoStar, to expand the audience for Ten-X auctions to include our online commercial real estate users. To increase exposure, we have upgraded LoopNet listings for properties to be auctioned on Ten-X and are allocating banner space on both our CoStar and LoopNet sites to Ten-X to cross-market our services.

•Continuing 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. We plan to create a dedicated sales team to support the

expected growth within the business. To support the LoopNet marketplace, we implemented training and incentive programs for our sales team to increase sales of LoopNet Signature Ads, with a focus on property owners.

•Continuing to invest in CoStar Suite, including capabilities that allow us to broaden the reach of CoStar Suite internationally by offering multiple languages and currencies on the platform. We plan to enhance CoStar Suite by making additional investments in analytical and service capabilities focused on lenders and owners of commercial real estate. In addition, we plan to invest in the technology and infrastructure of our other existing service offerings.

•Continuing to develop, improve and market our Apartments.com service offerings that focus on the digital rental experience and enable renters to apply for leases and make rent payments, and for landlords to run tenant credit and background checks, all online through a single platform. We seek user feedback and continue to aggressively market our multifamily listing services in an effort to provide more value to advertisers and, in turn, to attract advertisers. Our Apartments.com marketing investment is focused on search engine marketing and enhanced brand awareness. As we continue to assess the success and effectiveness of our marketing campaign, we will continue to work to determine the optimal level and focus of our marketing investment for our services for future periods and may adjust our marketing spend and focus as we deem appropriate.

•Obtaining necessary regulatory approvals to close the pending acquisition of RentPath and integrating RentPath with the Apartments.com network post-closing. Our wholly owned subsidiary entered into an asset purchase agreement (the "Asset Purchase Agreement") dated February 12, 2020, to acquire all of the equity interests of RentPath Holdings, Inc. for $588 million in cash, as reorganized following an internal restructuring pursuant to and under the joint chapter 11 plan of reorganization of RentPath and certain of its subsidiaries. The completion of the transaction is subject to customary conditions, including the expiration or termination of the applicable waiting period under applicable antitrust laws and bankruptcy approvals. On April 29, 2020, we and RentPath each received a request for additional information from the U.S. Federal Trade Commission (“FTC”) with respect to the acquisition. The FTC’s additional request extends the waiting period imposed by the Hart-Scott Rodino Antitrust Improvements Act of 1976 (the “HSR Act”) until the parties complete the compliance process and the FTC completes its review of the substance of the parties' submission. Bankruptcy court approval was obtained on June 9, 2020. On July 29, 2020, we exercised our option pursuant to the Asset Purchase Agreement to extend the date after which either party may terminate the Asset Purchase Agreement if the transaction has not closed (the "Outside Date") for an additional three months until November 12, 2020 in exchange for a payment of $7.5 million. We continue to engage with the FTC on the substance of its review, which we expect to conclude in the fourth quarter of 2020. See Note 5 to the accompanying Notes to the Condensed Consolidated Financial Statements included in Part I of this Quarterly Report on Form 10-Q for further discussion.

To support our continued expansion and development, we recently completed a public equity offering, a senior notes offering and the refinancing of our revolving credit facility. In May 2020, we completed a public equity offering of 2,633,587 shares of common stock for $655 per share. Net proceeds from the public equity offering were approximately $1.7 billion, after deducting approximately $35 million of underwriting fees, commissions and other stock issuance costs. We expect to use the net proceeds from the public equity offering to fund all or a portion of the costs of any strategic acquisitions we pursue in the future, to finance the growth of our business and/or for working capital and other general corporate purposes. General corporate purposes may include additions to working capital, capital expenditures, repayment of debt, investments in our subsidiaries, and the repurchase, redemption or retirement of securities, including our common stock.

On July 1, 2020, we issued $1.0 billion aggregate principal amount of 2.800% Senior Notes due July 15, 2030 (the “Senior Notes”). Interest on the Senior Notes is payable semi-annually in arrears beginning on January 15, 2021. We may redeem the Senior Notes in whole or in part (a) at any time prior to April 15, 2030, at a redemption price equal to 100% of the principal amount of the Senior Notes, plus the Applicable Premium (as calculated in accordance with the indenture governing the Senior Notes) as of, and any accrued and unpaid interest, if any, on the principal amount of Senior Notes being redeemed to, but excluding, the redemption date, and (b) on or after April 15, 2030, at a redemption price equal to 100% of the principal amount of the Senior Notes, plus any accrued and unpaid interest, if any, on the principal amount of Senior Notes being redeemed to, but excluding, the redemption date. We used a portion of the net proceeds from the issuance of the Senior Notes to repay outstanding borrowings under the 2017 Credit Agreement, and we intend to use the remaining proceeds to fund all or a portion of the costs of any strategic acquisitions we pursue in the future, to finance the growth of our business and/or for working capital and other general corporate purposes.

On July 1, 2020, we also entered into a second amended and restated credit agreement (the “2020 Credit Agreement”), which amended and restated in its entirety our existing credit agreement (the "2017 Credit Agreement"). The 2020 Credit Agreement provides for a $750 million revolving credit facility with a term of five years and a letter of credit sublimit of $20

million from a syndicate of financial institutions as lenders and issuing banks. On July 1, 2020, we repaid the outstanding borrowings under our existing $750 million revolving credit facility pursuant to the 2017 Credit Agreement using the proceeds from the issuance of the Senior Notes. Funds drawn down on the revolving credit facility pursuant to the 2020 Credit Agreement may be used for working capital and other general corporate purposes. The 2020 Credit Agreement, along with the proceeds from the May equity offering, the July Senior Notes offering and cash generated by our business are expected to support our continued growth and give us flexibility to act on strategic acquisition opportunities that may arise. See Note 10 and Note 14 to the accompanying Notes to the Condensed Consolidated Financial Statements included in Part I of this Quarterly Report on Form 10-Q for further discussion of our recent equity and Senior Notes offerings and our 2020 Credit Agreement.

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.

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 (expense) income and other (expense) income, 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 (expense) income and other (expense) income, 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, adjusted EBITDA margin, non-GAAP net income and non-GAAP net income per diluted share as operating performance measures. 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-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 without the impact of certain acquisition-related items. 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 these 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 without the impact of these items. 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 (expense) income and other (expense) income, 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 (expense) income and other (expense) income 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 (expense) income and other (expense) income to be a representative component of the day-to-day operating performance of our business.

•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 2020 and 2019, 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 investors to understand the factors and trends affecting our business.

Revenues. Revenues increased to $426 million for the three months ended September 30, 2020, from $353 million for the three months ended September 30, 2019. The $73 million increase was attributable to increases in revenues for several of our services, including a $29 million, or 23%, increase in multifamily revenue. The increase in multifamily revenues was primarily due to higher sales as a result of recent investments in marketing and upsells of existing customer packages to higher value advertising packages. Commercial property and land revenue increased $20 million, or 38%, due to revenue of $12 million from the acquisition of Ten-X, in addition to growth in sales of our LoopNet online marketplace services as a result of stronger traffic, driving sales of higher value advertisements as compared to the prior year. Information services revenue increased $14 million, or 70%, primarily due to revenue of $13 million from STR, which was acquired in the fourth quarter of 2019. CoStar Suite revenues increased $10 million, or 6%, primarily due to renewal price increases from prior periods and, to a lesser extent, higher sales volume.

Gross Profit. Gross profit increased to $348 million for the three months ended September 30, 2020, from $282 million for the three months ended September 30, 2019, and the gross profit percentage was 82% for the three months ended September 30, 2020, compared to 80% for the three months ended September 30, 2019. The increase in gross profit was due to higher revenues partially impacted by an increase in cost of revenues of $7 million, or 9%, primarily due to higher personnel costs of $4 million and intangible asset amortization of $2 million, primarily due to the acquisitions of STR and Ten-X.

Selling and Marketing Expenses. Selling and marketing expenses increased to $147 million for the three months ended September 30, 2020, from $102 million for the three months ended September 30, 2019. The $45 million increase was primarily attributable to a $17 million increase in marketing agency spending and a $15 million increase in search engine

marketing, primarily for multifamily, as well as a $3 million increase in other forms of marketing, and a $13 million increase in personnel costs. The increase in personnel costs was driven by increased headcount, as a result of the acquisitions of STR and Ten-X, as well as higher sales commissions. These increases were partially offset by a $3 million decrease in travel and entertainment expense.

Software Development Expenses. Software development expenses increased to $41 million for the three months ended September 30, 2020, from $33 million for the three months ended September 30, 2019, and increased as a percentage of revenues to 10% for the three months ended September 30, 2020 from 9% for the three months ended September 30, 2019. The $8 million increase was primarily due to a $7 million increase in personnel costs driven by increased headcount to enhance our product offerings, including $3 million due to the acquisitions of STR and Ten-X, as well as a $1 million increase in occupancy costs.

General and Administrative Expenses. General and administrative expenses increased to $65 million for the three months ended September 30, 2020, from $46 million for the three months ended September 30, 2019, and increased as a percentage of revenues to 15% for the three months ended September 30, 2020 from 13% for the three months ended September 30, 2019. The $19 million increase in the amount of general and administrative expense was primarily due to a $11 million increase in personnel costs as a result of increased headcount driven by the acquisitions of STR and Ten-X, a $4 million increase in professional services driven by acquisitions, a $3 million increase in credit loss expense primarily due to the Company's expectation that the economic downturn caused by the COVID-19 pandemic will increase delinquent trade receivables, and a $2 million increase in software and equipment costs.

Customer Base Amortization Expense. Customer base amortization expense increased to $18 million for the three months ended September 30, 2020 from $8 million for the three months ended September 30, 2019, and increased as a percentage of revenues to 4% for the three months ended September 30, 2020 from 2% for the three months ended September 30, 2019. The increase in customer base amortization expense was primarily due to the STR and Ten-X acquisitions.

Interest (Expense) Income. Interest (expense) income was a net expense of $8 million for the three months ended September 30, 2020 as compared to net interest income of $4 million for the three months ended September 30, 2019. The decrease for the three months ended September 30, 2020 was primarily due to interest expense of $7 million on our Senior Notes issued on July 1, 2020, as well as a decrease of $5 million in interest income caused by lower rates of return on our cash and cash equivalent balances compared to the prior year.

Other (Expense) Income. Other (expense) income, which is comprised primarily of foreign exchange gains and losses and other non-operating income and expenses, did not change materially for the three months ended September 30, 2020 and September 30, 2019.

Income Tax Expense. Income tax expense decreased to $11 million for the three months ended September 30, 2020 from $20 million for the three months ended September 30, 2019. The decrease was primarily due to lower income before income taxes, as well as an increase in excess tax benefits.

Comparison of Business Segment Results for Three Months Ended September 30, 2020 and Three Months Ended September 30, 2019

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. Management relies on an internal management reporting process that provides revenue and operating segment EBITDA, which is our net income before interest (expense) income and other (expense) income, loss on debt extinguishment, income taxes, depreciation and amortization. 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 our operating and management performance and to evaluate the performance of our 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 $411 million for the three months ended September 30, 2020, from $344 million for the three months ended September 30, 2019. The increase in North America revenues was attributable to increases in revenues for several of our services, including a $29 million increase in multifamily revenues driven by higher sales as a result of recent investments in marketing and upgrades of existing customer packages to higher value advertising packages. Commercial property and land revenues increased $20 million primarily due to the acquisition of Ten-X, and to a lesser extent, stronger traffic, driving sales of higher value advertisements in our LoopNet service offering. CoStar Suite and

information services revenue increased $9 million. The increase in CoStar Suite revenue was primarily due to renewal price increases and to a lesser extent, higher sales volume. The increase in information services was primarily due to the acquisition of STR. International revenues increased to $15 million for the three months ended September 30, 2020, from $9 million for the three months ended September 30, 2019. The increase in International revenues was primarily due to the acquisition of STR.

Segment EBITDA. North America EBITDA decreased to $108 million for the three months ended September 30, 2020, from $116 million for the three months ended September 30, 2019. The decrease in North America EBITDA was primarily due to increases in personnel, marketing and general and administrative costs, partially offset by an increase in revenue. International EBITDA for the three months ended September 30, 2020 was income of $0.6 million, as compared to a loss of $3 million for the three months ended September 30, 2019, as a result of increased revenue, offset by increases in personnel and general and administrative costs due to the acquisition of STR.

Revenues. Revenues increased to $1,215 million for the nine months ended September 30, 2020, from $1,025 million for the nine months ended September 30, 2019. The $190 million increase was attributable to increases in revenues for several of our services, including, a $78 million, or 22%, increase in multifamily revenue. The multifamily increase was due to higher sales volume as a result of recent investments in marketing and upsells of existing customer packages to higher value advertising packages. CoStar Suite revenues increased $39 million, or 9%, primarily due to renewal price increases from prior periods, and to a lesser extent, higher sales volume. Information services revenue increased $37 million, or 63%, primarily due to revenue of $39 million from STR, which was acquired in the fourth quarter of 2019, partially offset by a decrease in revenue from Real Estate Manager of $2 million. Commercial property and land revenue increased $35 million, or 24%, primarily due to growth in our LoopNet online marketplace services of $22 million as a result of stronger traffic, driving sales of higher value advertisements, and revenue of $12 million from the acquisition of Ten-X.

Gross Profit. Gross profit increased to $984 million for the nine months ended September 30, 2020, from $811 million for the nine months ended September 30, 2019, and the gross profit percentage was 81% for the nine months ended September 30, 2020, compared to 79% for the nine months ended September 30, 2019. The increase in gross profit was due to higher revenues partially offset by an increase in cost of revenues of $17 million, or 8%, primarily due to higher personnel costs of $10 million, including $8 million from the acquisitions of STR and Ten-X, merchant fees of $3 million, amortization of $3 million, IT equipment of $2 million and software maintenance costs of $2 million, partially offset by lower travel and entertainment costs of $2 million during the current year.

Selling and Marketing Expenses. Selling and marketing expenses increased to $402 million for the nine months ended September 30, 2020, from $309 million for the nine months ended September 30, 2019. The $93 million increase was attributable to increases of $43 million in search engine marketing and $23 million in marketing agency fees, primarily related to multifamily, and a $34 million increase in personnel costs driven by increased headcount, primarily due to additional multifamily sales personnel and the acquisitions of STR and Ten-X, as well as higher sales commissions. These increases were partially offset by a decrease of $4 million in other forms of marketing, driven by a decrease in spending on events.

Software Development Expenses. Software development expenses increased to $121 million for the nine months ended September 30, 2020, from $89 million for the nine months ended September 30, 2019, and increased as a percentage of revenues to 10% for the nine months ended September 30, 2020 from 9% for the nine months ended September 30, 2019. The $32 million increase in the amount of software development expense was primarily due to a $28 million increase in personnel costs as a result of increased headcount to enhance our product offerings, including $8 million due to the acquisitions of STR and Ten-X, as well as increases of $2 million in both supplies and office services and occupancy costs.

General and Administrative Expenses. General and administrative expenses increased to $182 million for the nine months ended September 30, 2020, from $128 million for the nine months ended September 30, 2019, and increased as a percentage of revenues to 15% for the nine months ended September 30, 2020 from 12% for the nine months ended September 30, 2019. The $54 million increase in the amount of general and administrative expense was primarily due to a $25 million increase in personnel costs as a result of increased headcount, including $16 million as a result of the acquisitions of STR and Ten-X, a $14 million increase in credit loss expense primarily due to the Company's expectations that the economic downturn caused by the COVID-19 pandemic will increase delinquent trade receivables, a $10 million increase in professional services related to acquisitions, and, to a lesser extent, additional increases in both software and equipment and occupancy costs.

Customer Base Amortization Expense. Customer base amortization expense increased to $45 million for the nine months ended September 30, 2020 from $22 million for the nine months ended September 30, 2019, and increased as a percentage of revenues to 4% for the nine months ended September 30, 2020 from 2% for the nine months ended September 30, 2019. The increase in customer base amortization expense was primarily due to the STR and Ten-X acquisitions.

Interest (Expense) Income. Interest (expense) income was a net expense of $9 million for the nine months ended September 30, 2020, as compared to net income of $13 million for the nine months ended September 30, 2019. The decrease during the nine months ended September 30, 2020 was due to an increase in interest expense of $12 million, of which, $5 million and $7 million was related to the $745 million draw on the 2017 Credit Agreement in the first quarter of 2020 and our Senior Notes issued on July 1, 2020, respectively. In addition, there was a decrease of $11 million in interest income caused by lower rates of return on our cash and cash equivalent balances compared to the prior year.

Other Income. Other income, which is comprised primarily of foreign exchange gains and losses and other non-operating income and expenses, did not change materially for the nine months ended September 30, 2020 compared to the nine months ended September 30, 2019.

Income Tax Expense. Income tax expense decreased to $33 million for the nine months ended September 30, 2020 from $50 million for the nine months ended September 30, 2019. The decrease was primarily due to lower income before income taxes for the nine months ended September 30, 2020, as well as an increase in excess tax benefits.

Comparison of Business Segment Results for Nine Months Ended September 30, 2020 and Nine Months Ended September 30, 2019

Segment Revenues. North America revenues increased to $1.2 billion for the nine months ended September 30, 2020, from $1.0 billion for the nine months ended September 30, 2019. The increase in North America revenues was attributable to increases in revenues for several of our services, including a $78 million increase in multifamily revenues driven by higher sales as a result of recent investments in marketing and upsells of existing customer packages to higher value advertising packages, and increases in CoStar Suite revenues of $37 million primarily due to price increases upon renewal of subscriptions in the past nine months, and to a lesser extent, higher sales. Commercial property and land revenues increased $36 million primarily due to growth in our LoopNet service offering and the acquisition of Ten-X. Information services increased $24 million due to the acquisition of STR. International revenues increased to $42 million for the nine months ended September 30, 2020, from $27 million for the nine months ended September 30, 2019. The increase in International revenues was primarily due to the acquisition of STR.

Segment EBITDA. North America EBITDA decreased to $323 million for the nine months ended September 30, 2020, from $327 million for the nine months ended September 30, 2019. The decrease in North America EBITDA was primarily due

to increases in personnel, marketing and general and administrative costs, partially offset by an increase in revenue. International EBITDA increased to a loss of $5 million for the nine months ended September 30, 2020 from a loss of $7 million for the nine months ended September 30, 2019, primarily as a result of increased revenue, offset by increases in personnel and general and administrative costs.

Liquidity and Capital Resources

Our principal sources of ongoing liquidity are cash from operations and more recently, proceeds from our debt and equity offerings. Total cash, cash equivalents and restricted cash increased to approximately $3.9 billion as of September 30, 2020, compared to cash and cash equivalents of approximately $1.1 billion as of December 31, 2019. The increase in cash, cash equivalents and restricted cash for the nine months ended September 30, 2020 was primarily due to proceeds from our May 2020 equity offering, net of transaction costs, of $1.7 billion, as well as proceeds from the July 2020 issuance of our Senior Notes, net of transaction costs, of $983 million. In addition, cash generated from operations contributed $355 million, partially offset by cash paid for acquisitions, net of cash acquired, of $192 million.

In May 2020, we completed a public equity offering of 2,633,587 shares of common stock for $655 per share and on July 1, 2020, we issued $1.0 billion aggregate principal amount of Senior Notes, entered into the 2020 Credit Agreement, which amended and restated in its entirety the 2017 Credit Agreement, and repaid in full the balance on the existing $750 million revolving credit facility under the 2017 Credit Agreement. For further discussion of our recent equity and Senior Notes offerings and our 2020 Credit Agreement, see “—Overview—Development, Investments and Expansion” and Note 10 and Note 14 to the accompanying Notes to the Condensed Consolidated Financial Statements included in Part I of this Quarterly Report on Form 10-Q for further discussion.

Net cash provided by operating activities for the nine months ended September 30, 2020 was approximately $355 million compared to approximately $350 million for the nine months ended September 30, 2019. The $5 million increase was primarily due to an increase in net income excluding certain non-cash expenses such as depreciation and amortization and credit loss expense, partially offset by a decrease in the change in working capital.

Net cash used in investing activities for the nine months ended September 30, 2020 was approximately $224 million compared to approximately $58 million of cash used in investing activities for the nine months ended September 30, 2019. The $166 million increase in cash used in investing activities was primarily due to an increase in cash paid for acquisitions, net of cash acquired, as a result of the acquisition of Ten-X for $184 million during the nine months ended September 30, 2020 as compared to $14 million used in the nine months ended September 30, 2019. The increase was partially offset by proceeds from the sale of our ARS investments of $10 million during the nine months ended September 30, 2020, as well as, a decrease in capital expenditures to $42 million compared to $44 million in the nine months ended September 30, 2019.

Net cash provided by financing activities for the nine months ended September 30, 2020 was approximately $2.7 billion compared to approximately $2 million used in financing activities for the nine months ended September 30, 2019. The $2.7 billion increase is primarily due to proceeds from our May 2020 equity offering, net of transaction costs, of $1.7 billion, as well as, proceeds from the issuance of our July 1, 2020 Senior Notes, net of transaction costs, of $983 million. We expect to use the proceeds from these transactions to fund all or a portion of the costs of any strategic acquisitions we pursue in the future, to finance the growth of our business and for working capital and other general corporate purposes. The increased cash position allows for greater financial flexibility in light of ongoing uncertainty in the global markets resulting from the COVID-19 pandemic. See Notes 10 and 14 to the accompanying Notes to the Condensed Consolidated Financial Statements included in Part I of this Quarterly Report on Form 10-Q for further discussion of our equity offering and Senior Notes.

Our future capital requirements will depend on many factors, including, among others, our operating results, expansion and integration efforts, our level of acquisition activity or other strategic transactions, and the future impact of the COVID-19 pandemic. To date, we have grown in part by acquiring other companies, and we expect to continue to make other acquisitions in the future. For example, on June 24, 2020, we acquired Ten-X for a purchase price of $187 million in cash. Our wholly owned subsidiary entered into an Asset 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. On July 29, 2020, we exercised our option pursuant to the asset purchase agreement for the RentPath acquisition to extend the Outside Date under that agreement for an additional three months until November 12, 2020, in exchange for payment of $7.5 million. In accordance with the Asset Purchase Agreement, we paid a $59 million break fee into a cash escrow account. In the event the Asset Purchase Agreement is terminated under specified circumstances and either certain antitrust approvals are not obtained, or a governmental order related to antitrust or competition matters prohibits the consummation of the transaction, this amount is not refundable to us. As the transaction had not closed as of September 30, 2020, the break fee is recorded as restricted cash within cash, cash equivalents and restricted cash on the Company's condensed consolidated balance sheets. See Note 5 to the

accompanying Notes to the Condensed Consolidated Financial Statements included in Part I of this Quarterly Report on Form 10-Q for further discussion.

On March 27, 2020, President Trump signed into law the Coronavirus Aid, Relief and Economic Security Act (the "CARES Act"). The CARES Act, among other things, includes provisions relating to the deferral of taxes, valuation allowances, and balance sheet classifications, as well as provisions relating to refundable payroll tax credits, deferral of employer social security payments, net operating loss carryback periods, alternative minimum tax credit refunds, modifications to the net interest deduction limitations and technical corrections to tax depreciation methods for qualified improvement property. As permitted under the CARES Act, we are currently deferring payroll taxes due in 2020 to 2021 and 2022.

As of the filing date of this Quarterly Report on Form 10-Q, we believe that our available cash combined with positive cash flows provided by operating activities should be sufficient for us to maintain and fund our operations for at least the next twelve months. Our ability to maintain adequate capital for our operations in the future is dependent upon numerous rapidly evolving factors, many of which we cannot accurately predict or assess, including, among others, the length and severity of the economic downturn associated with the COVID-19 pandemic, related disruption of the international and national economy and credit markets; actions taken by governments, businesses and individuals in response to the pandemic such as office and other workplace closures, worker absenteeism, quarantines, mass-transit disruptions or other travel or health-related restrictions; how quickly economies, including the commercial real estate industry in particular, recover after the pandemic subsidies; sales of our services; and collection of accounts receivables. We plan to continue to monitor and evaluate the financial impact of the COVID-19 pandemic as it evolves.

The preparation of financial statements and related disclosures in conformity with 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

For an in-depth discussion of each of our significant accounting policies, including our critical accounting policies and further information regarding estimates and assumptions involved in their application, see our Annual Report on Form 10-K for the year ended December 31, 2019 and Note 2 to the accompanying Notes to the Condensed Consolidated Financial Statements included in Part I of this Quarterly Report on Form 10-Q.

Cautionary Statement Concerning Forward-Looking Statements

We have made forward-looking statements in this Quarterly Report on Form 10-Q and make forward-looking statements in our press releases, conference calls, Annual Reports on Form 10-K, other Quarterly Reports on Form 10-Q, Current Reports on Form 8-K and other filings with the Securities and Exchange Commission that are subject to risks and uncertainties. Forward-looking statements include information that is not purely historic fact and include, without limitation, statements concerning our financial outlook for the remainder of 2020 and beyond, our possible or assumed future results of operations generally, and other statements and information regarding assumptions about our revenues, revenue growth rates, gross margin percentage, net income, net income per share, fully diluted net income per share, EBITDA, adjusted EBITDA, adjusted EBITDA margin, non-

The following important factors, in addition to those discussed or referred to under the heading “Risk Factors,” and other unforeseen events or circumstances, could affect our future results and could cause those results or other outcomes to differ materially from those expressed or implied in our forward-looking statements: the effects of and uncertainty surrounding the COVID-19 pandemic, including the length and severity of the economic downturn associated with the COVID-19 pandemic, including disruption of the international and national economy and credit markets; actions taken by governments, businesses and individuals in response to the COVID-19 pandemic such as office and other workplace closures, worker absenteeism or decreased productivity, quarantines, mass-transit disruptions or other travel or health-related restrictions; how quickly economies, including the commercial real estate industry in particular, recover after the COVID-19 pandemic subsides; commercial real estate market conditions; general economic conditions, both domestic and international, including the impacts of “Brexit” and uncertainty from the expected discontinuance of LIBOR and the transition to any other interest rate benchmark; our ability to identify and acquire additional acquisition candidates; the possibility that the acquisition of RentPath does not close when expected or at all; the risk that the bankruptcy process may cause greater business disruption for RentPath than expected; our ability to realize the expected benefits, cost savings or other synergies from acquisitions, including STR, Ten-X and RentPath, on a timely basis or at all; our ability to combine acquired businesses, successfully or in a timely and cost-efficient manner; business disruption relating to integration of acquired businesses; or other business initiatives; the risk that expected investments in acquired businesses, or the timing of any such investments, may change or may not produce the expected results; our ability to transition acquired service platforms to our model in a timely manner or at all; changes and developments in business plans and operations; theft of any personally identifiable information we, or the businesses that we acquire, maintain, store or process; any actual or perceived failure to comply with privacy or data protection laws, regulations or standards; any disruption of our systems, including due to any cyberattack or other similar event; the amount of investment for sales and marketing and our ability to realize a return on investments in sales and marketing; our ability to effectively and strategically combine, eliminate or de-emphasize service offerings; reductions in revenues as a result of service changes; the time and resources required to develop upgraded or new services and to expand service offerings; changes or consolidations within the commercial real estate industry; customer retention; our ability to attract new clients and to sell additional services to existing clients; our ability to develop, successfully introduce and cross-sell new products or upgraded services in U.S. and foreign markets; our ability to attract consumers to our online marketplaces; our ability to increase traffic on our network of sites; the success of our marketing campaigns in generating brand awareness and site traffic; our ability to protect and defend our intellectual property including unauthorized or unlicensed use of our services; competition; foreign currency fluctuations; global credit market conditions affecting investments; our ability to continue to expand successfully, timely and in a cost-efficient manner, including internationally; our ability to effectively penetrate and gain acceptance in new sectors and geographies; our ability to control costs; litigation or government investigations in which we become involved; changes in accounting policies or practices; release of new and upgraded services or entry into new markets by us or our competitors; data quality; expansion, growth, development or reorganization of our sales force; employee retention, including retention of employees of acquired businesses; technical problems with our services; managerial execution; changes in relationships with real estate brokers, property managers and other strategic partners; legal and regulatory issues, including any actual or perceived failure to comply with U.S. or international laws, rules or regulations; and successful adoption of and training on our services; competitive conditions; and the availability of capital.

Accordingly, you should not place undue reliance on forward-looking statements, which speak only as of, and are based on information available to us on, the date of this Quarterly Report on Form 10-Q (unless otherwise indicated). All subsequent

written and oral forward-looking statements attributable to us or any person acting on our behalf are expressly qualified in their entirety by the cautionary statements contained or referred to in this section. We do not undertake any obligation to update any such statements or release publicly any revisions to these forward-looking statements to reflect new information or events or circumstances after the date of this Report or to reflect the occurrence of unanticipated events.

Item 3.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 three and nine months ended September 30, 2020, revenues denominated in foreign currencies was approximately 4% and 5%, respectively, of total revenue, respectively. For the three and nine months ended September 30, 2020, our revenues would have decreased by approximately $1.9 million and $5.6 million, respectively, if the U.S. dollar exchange rate used strengthened by 10%. For the three and nine months ended September 30, 2020, our revenues would have increased by approximately $1.9 million and $5.6 million, respectively, if the U.S. dollar exchange rate used weakened by 10%. 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 September 30, 2020, accumulated other comprehensive loss included a loss from foreign currency translation adjustments of approximately $12 million.

We do not have material exposure to market risks associated with changes in interest rates related to cash equivalent securities held as of September 30, 2020. As of September 30, 2020, we had $3.9 billion of cash, cash equivalents and restricted cash. 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. We currently diversify our cash and cash equivalents holdings amongst multiple financial institutions. We are subject to interest rate market risk in connection with our new revolving credit facility. On July 1, 2020, we entered into the 2020 Credit Agreement, which provides for variable rate borrowings of up to $750 million. On July 1, 2020, we issued $1.0 billion aggregate principal amount of 2.800% Senior Notes due July 15, 2030. Changes in interest rates would not have a material impact to our current interest and debt financing expense, as all our borrowings except for our credit facility are fixed rate, and our credit facility is currently undrawn as of September 30, 2020. See Note 10 to the accompanying Condensed Consolidated Financial Statements included in Part I of this Quarterly Report on Form 10-Q for information regarding our 2020 Credit Agreement.

We had approximately $2.4 billion of goodwill and intangible assets as of September 30, 2020. As of September 30, 2020, we believe our intangible assets will be recoverable; however, changes in the economy, including due to the COVID-19 pandemic, 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.

Item 4.Controls and Procedures

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 Securities Exchange Act of 1934 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.

As of September 30, 2020, 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. Based on the foregoing, our Chief Executive Officer and Chief Financial Officer concluded that our disclosure controls and procedures were effective as of September 30, 2020 and were operating at a reasonable assurance level.

We continue 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 further 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 quarter that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting. We continue to monitor and assess the effects of the COVID-19 pandemic and our response to the pandemic on our internal controls so we can take appropriate actions to minimize any impact on the design and operating effectiveness.

PART II — OTHER INFORMATION

Item 1.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 results of operations. See Note 12 of the Notes to the Condensed Consolidated Financial Statements included in Part I of this Quarterly Report on Form 10-Q for further discussion.

Item 1A.Risk Factors

Except as updated in our Quarterly Reports for the periods ended March 31, 2020 and June 30, 2020, there have been no material changes to the Risk Factors as previously disclosed in Part I, “Item 1A Risk Factors” in our Annual Report on Form 10-K for the year ended December 31, 2019 (the “2019 Form 10-K”), which could materially affect our business, financial condition or future results. The risks described in our 2019 Form 10-K are not the only risks facing our Company. Additional risks and uncertainties not currently known to us or that we currently deem to be immaterial also may materially adversely affect our business, financial condition and/or results of operations.
