NOTE REGARDING FORWARD-LOOKING STATEMENTS

This Quarterly Report on Form 10-Q, including Part I, Item 2 (Management’s Discussion and Analysis of Financial Condition and Results of Operations), contains forward-looking statements based on our management’s beliefs and assumptions and on information currently available to our management. Forward-looking statements include all statements that are not historical facts and generally may be identified by terms such as “believe,” “may,” “will,” “estimate,” “continue,” “anticipate,” “intend,” “could,” “would,” “project,” “plan,” “expect,” “potential,” “might” or the negative or plural of these words or similar expressions.

These forward-looking statements are subject to a number of risks, uncertainties and assumptions, including those risks, uncertainties and assumptions described in Part I, Item 1A (Risk Factors) in our Annual Report on Form 10-K for the fiscal year ended December 31, 2023, including, but not limited to risks related to:

•the current and future health and stability of the economy and United States residential real estate industry, including changes in inflationary conditions, interest rates, housing availability and affordability, labor shortages and supply chain issues;

•our ability to manage advertising and product inventory and pricing and maintain relationships with our real estate partners;

•our ability to establish or maintain relationships with listing and data providers, which affects traffic to our mobile applications and websites;

•our ability to comply with current and future rules and requirements promulgated by the National Association of REALTORS®, multiple listing services, or other real estate industry groups or governing bodies;

•our ability to navigate industry changes, including as a result of certain or future class action lawsuits or government investigations, which may include lawsuits or investigations in which we are not a named party;

•our ability to continue to innovate and compete to attract customers and real estate partners;

•our ability to effectively invest resources to pursue new strategies, develop new products and services and expand existing products and services into new markets;

•our ability to operate and grow Zillow Home Loans, our mortgage origination business, including the ability to obtain or maintain sufficient financing to fund its origination of mortgages, meet customers’ financing needs with its product offerings, continue to grow the origination business and resell originated mortgages on the secondary market;

•the duration and impact of natural disasters, geopolitical events, and other catastrophic events (including public health crises) on our ability to operate, demand for our products or services, or general economic conditions;

•our ability to maintain adequate security measures or technology systems, or those of third parties on which we rely, to protect data integrity and the information and privacy of our customers and other third parties;

•the impact of pending or future litigation and other disputes or enforcement actions, which may include lawsuits or investigations to which we are not a party;

•our ability to attract, engage, and retain a highly skilled, remote workforce;

•acquisitions, investments, strategic partnerships, capital-raising activities, or other corporate transactions or commitments by us or our competitors;

•our ability to continue relying on third-party services to support critical functions of our business;

•our ability to protect and continue using our intellectual property and prevent others from copying, infringing upon, or developing similar intellectual property, including as a result of generative artificial intelligence;

•our ability to comply with domestic and international laws, regulations, rules, contractual obligations, policies and other obligations, or to obtain or maintain required licenses to support our business and operations;

•our ability to pay debt, settle conversions of our Notes, or repurchase our Notes upon a fundamental change;

•our ability to raise additional capital or refinance on acceptable terms, or at all;

•actual or anticipated fluctuations in quarterly and annual results of operations and financial position;

•the assumptions, estimates and internal or third-party data that we use to calculate business, performance and operating metrics; and

•volatility of our Class A common stock and Class C capital stock prices.

Moreover, we operate in a very competitive and rapidly changing environment. New risks emerge from time to time. It is not possible for our management to predict all risks, nor can we assess the effect of all factors on our business or the extent to which any factor, or combination of factors, may cause actual results to differ materially from those contained in any forward-looking statements we may make. In light of these risks, uncertainties and assumptions, the forward-looking events and circumstances discussed in this report may not occur and actual results could differ materially and adversely from those anticipated or implied in the forward-looking statements.

2

You should not rely on forward-looking statements as predictions of future events. Although we believe that the expectations reflected in the forward-looking statements are reasonable, we cannot guarantee that the future results, levels of activity, performance or events and circumstances reflected in the forward-looking statements will be achieved or occur. Moreover, except as required by law, neither we nor any other person assumes responsibility for the accuracy and completeness of the forward-looking statements, and we undertake no obligation to update publicly any forward-looking statements for any reason after the date of this report to conform these statements to actual results or to changes in our expectations.

In addition, statements such as “we believe” and similar statements reflect our beliefs and opinions on the relevant subject. These statements are based on information available to us as of the date of this Quarterly Report on Form 10-Q. While we believe that such information provides a reasonable basis for these statements, that information may be limited or incomplete. Our statements should not be read to indicate that we have conducted an exhaustive inquiry into, or review of, all relevant information. These statements are inherently uncertain, and investors are cautioned not to unduly rely on these statements.

Note 1. Organization and Description of Business

Zillow Group is reimagining real estate to make home a reality for more and more people. As the most visited real estate website in the United States, Zillow and its affiliates help people find and get the home they want by connecting them with digital solutions, dedicated partners and agents, and easier buying, selling, financing and renting experiences.

Our portfolio of affiliates, subsidiaries and brands includes Zillow Premier Agent, Zillow Home Loans, our mortgage originations business and affiliate lender, Zillow Rentals, Trulia, StreetEasy, HotPads and Out East. In addition, Zillow Group provides a comprehensive suite of marketing software and technology solutions for the real estate industry, including ShowingTime+, Spruce and Follow Up Boss.

Certain Significant Risks and Uncertainties

We operate in a dynamic industry and, accordingly, can be affected by a variety of factors, which are uncertain and difficult to predict. For example, we believe that changes in any of the following areas could have a significant negative effect on us in terms of our future financial position, results of operations or cash flows: current and future health and stability of the economy and United States residential real estate industry, including changes in inflationary conditions, interest rates, housing availability and affordability, labor shortages and supply chain issues; our ability to manage industry changes, including as a result of certain or future class action lawsuits or government investigations; our ability to manage advertising and product inventory and pricing and maintain relationships with our real estate partners; our ability to comply with current and future rules and requirements promulgated by the National Association of REALTORS®, multiple listing services, or other real estate industry groups or governing bodies, and to maintain or establish relationships with listing and data providers; our investment of resources to pursue strategies and develop new products and services that may not prove effective or that are not attractive for customers and real estate partners or that do not allow us to compete successfully; our ability to operate and grow Zillow Home Loans, our mortgage origination business and affiliate lender, including the ability to obtain or maintain sufficient financing and resell originated mortgages on the secondary market; the duration and impact of natural disasters and other catastrophic events (including public health crises) on our ability to operate, demand for our products or services or general economic conditions; outcomes of legal proceedings; our ability to attract, engage, and retain a highly skilled, remote workforce; protection of Zillow Group’s information and systems against security breaches or disruptions in operations; reliance on third-party services to support critical functions of our business; protection of our brand and intellectual property; and changes in laws or government regulation affecting our business, among other things.

Note 2. Summary of Significant Accounting Policies

Basis of Presentation

The accompanying condensed consolidated financial statements include Zillow Group, Inc. and its wholly owned subsidiaries. All intercompany balances and transactions have been eliminated in consolidation. These condensed consolidated financial statements have been prepared in conformity with United States GAAP and applicable rules and regulations of the SEC regarding interim financial reporting. Certain information and note disclosures normally included in the financial statements prepared in accordance with GAAP have been condensed or omitted pursuant to such rules and regulations. Accordingly, these interim condensed consolidated financial statements should be read in conjunction with the audited financial statements and accompanying notes included in Zillow Group, Inc.’s Annual Report on Form 10-K for the fiscal year ended December 31, 2023. The condensed consolidated balance sheet as of December 31, 2023, included herein, was derived from the audited financial statements of Zillow Group, Inc. as of that date. Certain reclassifications of prior period amounts have been made to conform to the current period presentation.

The unaudited condensed consolidated interim financial statements, in the opinion of management, reflect all adjustments, consisting only of normal recurring adjustments, necessary to present fairly our financial position as of March 31, 2024 and our results of operations, comprehensive loss, shareholders’ equity, and cash flows for the three month periods ended March 31, 2024 and 2023. The results for the three months ended March 31, 2024 are not necessarily indicative of the results to be expected for the year ending December 31, 2024, for any interim period, or for any other future year.

Use of Estimates

The preparation of financial statements in conformity with GAAP requires management to make certain estimates, judgments and assumptions that affect the reported amounts of assets and liabilities and the related disclosures at the date of the financial statements, as well as the reported amounts of revenue and expenses during the periods presented. On an ongoing basis, we evaluate our estimates, including those related to the accounting for certain revenue offerings, amortization period and recoverability of contract cost assets, website and software development costs, recoverability of long-lived assets and intangible assets, share-based compensation, income taxes, business combinations, including the initial and subsequent fair value measurements of assets (primarily intangible assets), liabilities and contingent consideration, and the recoverability of goodwill, among others. To the extent there are material differences between these estimates, judgments or assumptions and actual results, our financial statements will be affected. The health of the housing market and broader economy have introduced significant additional uncertainty with respect to estimates, judgments and assumptions, which may materially impact the estimates previously listed, among others.

Recently Adopted Accounting Standards

In June 2022, the FASB issued guidance to improve existing measurement and disclosure requirements for equity securities that are subject to a contractual sale restriction. This guidance is effective for interim and annual periods beginning after December 15, 2023 on a prospective basis, with early adoption permitted. We adopted this guidance on January 1, 2024, which did not have a material impact on our financial position, results of operations or cash flows.

Recently Issued Accounting Standards Not Yet Adopted

In November 2023, the FASB issued guidance to improve existing disclosure requirements for segment reporting, primarily through enhanced disclosures about significant segment expenses and new disclosures requirements applicable to entities with a single reportable segment. This guidance is effective for annual periods beginning after December 15, 2023 and interim periods beginning after December 15, 2024, on a retrospective basis. We expect to adopt this guidance for the annual period ending December 31, 2024 and have not yet determined the impact the adoption of this guidance will have on our consolidated financial statements.

In December 2023, the FASB issued guidance to enhance the income tax rate reconciliation disclosure requirements and to provide clarity on disclosure requirements for income taxes. This guidance is effective for annual periods beginning after December 15, 2024, and can be applied on a prospective or retrospective basis, with early adoption permitted. We expect to adopt this guidance for the annual period ending December 31, 2025 using the retrospective approach and have not yet determined the impact the adoption of this guidance will have on our consolidated financial statements.

10

Note 3. Financial Instruments

We apply the following methods and assumptions in estimating our fair value measurements:

Cash equivalents — The fair value measurement of money market funds is based on quoted market prices in active markets (Level 1). The fair value measurement of other cash equivalents is based on observable market-based inputs principally derived from or corroborated by observable market data (Level 2).

Short-term investments — The fair value measurement of our short-term investments is based on observable market-based inputs or inputs that are derived principally from or corroborated by observable market data by correlation or other means (Level 2).

Restricted cash — The carrying value of restricted cash approximates fair value due to the short period of time that amounts are held in escrow (Level 1).

Mortgage loans held for sale — The fair value of mortgage loans held for sale is generally calculated by reference to quoted prices in secondary markets for commitments to sell mortgage loans with similar characteristics (Level 2).

Forward contracts — The fair value of mandatory loan sales commitments and derivative instruments such as forward sales of mortgage-backed securities that are utilized as economic hedging instruments is calculated by reference to quoted prices for similar assets (Level 2).

Contingent consideration — In December 2023, Zillow Group acquired Follow Up Boss, a customer relationship management system for real estate professionals, for $399 million in cash, net of cash acquired, and contingent consideration of up to $100 million, payable over a three-year period upon achievement of certain performance metrics. The fair value of the contingent consideration is estimated using a Monte Carlo simulation which considers the probabilities of the achievement of certain performance metrics (Level 3).

The discount rates used in our valuation of contingent consideration are based on our estimated cost of debt and are directly related to the fair value of contingent consideration. An increase in the discount rate, in isolation, would result in a decrease in the fair value measurement. Conversely, a decrease in the discount rate, in isolation, would result in an increase in the fair value measurement. The probabilities of achieving the relevant performance metrics used in our valuation of contingent consideration are directly related to the fair value of contingent consideration, as an increase in the probability, in isolation, would result in an increase in the fair value measurement. Conversely, a decrease in the probability, in isolation, would result in a decrease in the fair value measurement.

During the three months ended March 31, 2024, there were no material changes in the unobservable inputs used in determining the fair value of contingent consideration included in our Annual Report on Form 10-K for the fiscal year ended December 31, 2023.

Interest rate lock commitments — The fair value of IRLCs is calculated by reference to quoted prices in secondary markets for commitments to sell mortgage loans with similar characteristics. Expired commitments are excluded from the fair value measurement. Since not all IRLCs will become closed loans, we adjust our fair value measurements for the estimated amount of IRLCs that will not close. This adjustment is effected through the pull-through rate, which represents the probability that an IRLC will ultimately result in a closed loan. For IRLCs that are canceled or expire, any recorded gain or loss is reversed at the end of the commitment period (Level 3).

The pull-through rate is based on estimated changes in market conditions, loan stage and historical borrower behavior. Pull-through rates are directly related to the fair value of IRLCs as an increase in the pull-through rate, in isolation, would result in an increase in the fair value measurement. Conversely, a decrease in the pull-through rate, in isolation, would result in a decrease in the fair value measurement. Changes in the fair value of IRLCs are included within revenue in our condensed

consolidated statements of operations. The following table presents the range and weighted-average pull-through rates used in determining the fair value of IRLCs as of the dates presented:

	March 31, 2024	December 31, 2023
Range	61% - 100%	45% - 100%
Weighted-average	87%	85%

We manage our interest rate risk related to IRLCs and mortgage loans held for sale through the use of derivative instruments, generally forward contracts on MBSs, which are commitments to either purchase or sell a financial instrument at a future date for a specified price, and mandatory loan commitments, which are an obligation by an investor to buy loans at a specified price within a specified time period. We do not enter into or hold derivatives for trading or speculative purposes, and our derivatives are not designated as hedging instruments. Changes in the fair value of our derivative financial instruments are recognized in revenue in our condensed consolidated statements of operations.

The following table presents the notional amounts of the economic hedging instruments related to our mortgage loans held for sale as of the dates presented (in millions):

Note 5. Acquisitions

Acquisition of Follow Up Boss

On December 8, 2023, Zillow Group acquired Follow Up Boss, a customer relationship management system for real estate professionals, for $399 million in cash, net of cash acquired, and contingent consideration of up to $100 million in cash, payable over a three-year period upon achievement of certain performance metrics. See Note 3 for additional information regarding the preliminary fair value of contingent consideration. The acquisition is consistent with our strategy to invest in a more integrated software experience for our customers. The acquisition of Follow Up Boss has been accounted for as a business combination, and assets acquired and liabilities assumed were generally recorded at their preliminary estimated fair values, in accordance with the applicable accounting guidance. Goodwill represents the expected synergies from combining the acquired assets and the operations of the acquirer as well as intangible assets that do not qualify for separate recognition. Goodwill recorded in connection with the acquisition is deductible for tax purposes.

The total preliminary purchase price has been allocated to the assets acquired and liabilities assumed, including identifiable intangible assets, based on their preliminarily estimated fair values at the acquisition date, as follows (in millions):

Preliminary purchase price:
Cash	$	403
Contingent consideration	81
Total preliminary purchase price	$	484
Identifiable assets acquired and liabilities assumed:
Cash and cash equivalents	$	4
Goodwill	401
Intangible assets	86
Other assets	1
Deferred revenue	(7)
Other liabilities	(1)
Total preliminary purchase price	$	484

The preliminary estimated fair value of the identifiable intangible assets acquired and associated useful lives consisted of the following (in millions):

14

	Preliminary Estimated Fair Value		Estimated Weighted-Average Useful Life (in years)
Developed technology	$	50	4
Customer relationships	34		7
Trade names and trademarks	2		7
Total	$	86

Estimated fair values of the identifiable intangible assets acquired were determined by management, based in part on a preliminary valuation performed by an independent third-party valuation specialist. We used an income approach to measure the fair value of the customer relationships intangible asset acquired based on the excess earnings method, whereby the fair value is estimated based upon the present value of cash flows that the applicable asset is expected to generate. We used an income approach to measure the fair value of the developed technology and trade names and trademarks based on the relief-from-royalty method. These fair value measurements were based on Level 3 inputs under the fair value hierarchy.

The purchase price allocation for the Follow Up Boss acquisition is preliminary and subject to change during the measurement period up to one year from the acquisition date. We made an initial allocation of the purchase price at the date of the acquisition based upon information available and our understanding of the estimates used to determine the preliminary fair value of acquired assets, assumed liabilities and contingent consideration. We are in the process of specifically identifying the amounts assigned to certain tangible assets acquired and liabilities assumed and contingent consideration. As of March 31, 2024, the measurement period (not to extend beyond one year) is open for the Follow Up Boss acquisition; therefore, assets acquired, liabilities assumed, and contingent consideration are subject to adjustment until the end of the measurement period.

Acquisition-related costs incurred, which primarily included legal, accounting and other external costs directly related to the acquisition, are included within acquisition-related costs in our consolidated statements of operations and were expensed as incurred.

Unaudited pro forma revenue and earnings information has not been presented as the effects were not material to our condensed consolidated financial statements.

Acquisitions of Aryeo and Spruce

On July 31, 2023, Zillow Group acquired Aryeo, a software company that serves real estate photographers, in exchange for approximately $15 million in cash, net of cash acquired, and 380,259 shares of our Class C capital stock with a value of $20 million, for total consideration of $35 million, net of cash acquired. On September 11, 2023, Zillow Group acquired substantially all of the assets and liabilities of Spruce, a tech-enabled title and escrow platform, in exchange for approximately $19 million in cash, net of cash acquired.

The acquisitions of Aryeo and Spruce have been accounted for as business combinations, and assets acquired and liabilities assumed were recorded at their estimated fair values. Goodwill represents the expected synergies from combining the acquired assets and the operations of the acquirer as well as intangible assets that do not qualify for separate recognition. Goodwill recorded in connection with the acquisition of Aryeo is not deductible for tax purposes, and goodwill recorded in connection with the acquisition of Spruce is deductible for tax purposes.

The total purchase prices have been allocated to the assets acquired and liabilities assumed, including identifiable intangible assets, based on their respective fair values at the acquisition date, as follows (in millions):

	Aryeo		Spruce
Cash and cash equivalents	$	3	$	5
Goodwill	26		16

We used an income approach to measure the fair value of the customer relationships intangible asset acquired from Aryeo based on the excess earnings method, whereby the fair value is estimated based upon the present value of cash flows that the applicable asset is expected to generate. We used a cost approach to measure the fair value of purchased content acquired from Aryeo. We used an income approach to measure the fair value of the developed technology acquired from Aryeo and Spruce based on the relief-from-royalty method. These fair value measurements were based on Level 3 inputs under the fair value hierarchy.

Aggregate acquisition-related costs for the acquisitions of Follow Up Boss, Aryeo, and Spruce were not material to our financial statements.

Unaudited pro forma revenue and earnings information related to the acquisitions has not been presented as the aggregate effects of the acquisitions of Follow Up Boss, Aryeo and Spruce were not material to our condensed consolidated financial statements.

Credit Facilities

We utilize master repurchase agreements to provide capital for Zillow Home Loans. The following table summarizes certain details related to our outstanding master repurchase agreements as of March 31, 2024 (in millions, except interest rates):

Lender	Maturity Date	Maximum Borrowing Capacity		Borrowings Outstanding		Available Borrowing Capacity		Weighted-Average Interest Rate
JPMorgan Chase Bank, N.A.	May 30, 2024	$	100	$	65	$	35	7.03	%
UBS AG	October 9, 2024	100		58		42		7.05	%
	Total	$	200	$	123	$	77

In accordance with the master repurchase agreements, the Lenders agreed to pay Zillow Home Loans a negotiated purchase price for eligible loans, and Zillow Home Loans simultaneously agreed to repurchase such loans from the Lenders under a specified timeframe at an agreed upon price that includes interest. The master repurchase agreements contain margin call provisions that provide the Lenders with certain rights in the event of a decline in the market value of the assets purchased under the master repurchase agreements. As of March 31, 2024 and December 31, 2023, $128 million and $99 million, respectively, in mortgage loans held for sale were pledged as collateral under the master repurchase agreements.

Borrowings on the master repurchase agreements bear interest at a floating rate based on SOFR plus an applicable margin, as defined by the governing agreements. The master repurchase agreements include customary representations and warranties, covenants and provisions regarding events of default. As of March 31, 2024, Zillow Home Loans was in compliance with all financial covenants and no event of default had occurred. The master repurchase agreements are recourse to Zillow Home Loans, and have no recourse to Zillow Group or any of its other subsidiaries.

The Notes are senior unsecured obligations. The 2026 Notes and 2025 Notes are classified as long-term debt and the 2024 Notes are classified as current liabilities in our condensed consolidated balance sheets based on their contractual maturity dates. Interest on the convertible notes is paid semi-annually in arrears. The estimated fair value of the Notes is classified as Level 2 and was determined through consideration of quoted market prices in markets that are not active.

The Notes are convertible into cash, shares of Class C capital stock or a combination thereof, at our election, and may be settled as described below. They will mature on their respective maturity dates, unless earlier repurchased, redeemed or converted in accordance with their terms. The following table summarizes the conversion and redemption options with respect to the Notes:

Maturity Date	Early Conversion Date	Conversion Rate	Conversion Price		Optional Redemption Date

There were no conversions of the Notes during the three months ended March 31, 2024 or 2023.

The last reported sale price of our Class C capital stock did not exceed 130% of the conversion price of each series of the Notes for more than 20 trading days during the 30 consecutive trading days ended March 31, 2024. Accordingly, each series of the Notes is not redeemable or convertible at the option of the holders during the three months ending June 30, 2024.

For additional details related to our convertible senior notes, see Note 11 in the Notes to Consolidated Financial Statements included in our Annual Report on Form 10-K for the fiscal year ended December 31, 2023.

Note 8. Income Taxes

We are subject to income taxes in the United States (federal and state) and certain foreign jurisdictions. As of March 31, 2024 and December 31, 2023, we have provided a valuation allowance against our net deferred tax assets that we believe, based on the weight of available evidence, are not more likely than not to be realized. We have accumulated federal tax losses of approximately $1.4 billion as of December 31, 2023, which are available to reduce future taxable income. We have accumulated state tax losses of approximately $56 million (tax effected) as of December 31, 2023.

Our income tax expense or benefit for interim periods is determined using an estimate of our annual effective tax rate, adjusted for discrete items, if any, that are taken into account for the relevant period. We update our estimate of the annual effective tax rate on a quarterly basis and make year-to-date adjustments to the tax provision or benefit, as applicable. Our income tax expense (benefit) was not material for the three months ended March 31, 2024 and 2023.

Note 9. Share Repurchase Authorizations

The Board has authorized the repurchase of up to $2.5 billion of our Class A common stock, Class C capital stock, outstanding convertible senior notes or a combination thereof. For additional information on these authorizations, see Note 13 in the Notes to Consolidated Financial Statements included in our Annual Report on Form 10-K for the fiscal year ended December 31, 2023.

Repurchases of stock under the Repurchase Authorizations may be made in open-market transactions or privately negotiated transactions, or in such other manner as deemed appropriate by management, and may be made from time to time as determined by management depending on market conditions, share price, trading volume, cash needs and other business factors, in each case as permitted by securities laws and other legal requirements. As of March 31, 2024, $761 million remained available for future repurchases pursuant to the Repurchase Authorizations.

As of May 1, 2024, $670 million remained available for future repurchases pursuant to the Repurchase Authorizations.

Note 10. Share-Based Awards

In addition to the option awards and restricted stock units typically granted under the 2020 Plan which vest quarterly over four years, during the first quarter of 2023, the Compensation Committee of the Board approved option and restricted stock unit awards granted under the 2020 Plan in connection with the 2022 annual review cycle that vest quarterly over three years. The exercisability terms of these equity awards are otherwise consistent with the terms of the option awards and restricted stock units typically granted under the 2020 Plan. For additional information regarding our share-based awards, see Note 14 in the Notes to the Consolidated Financial Statements in our Annual Report on Form 10-K for the fiscal year ended December 31, 2023.

Note 12. Commitments and Contingencies

Commitments

During the three months ended March 31, 2024, there were no material changes to the commitments disclosed in Note 16 in the Notes to the Consolidated Financial Statements included in our Annual Report on Form 10-K for the fiscal year ended December 31, 2023.

Legal Proceedings

We are involved in a number of legal proceedings concerning matters arising in connection with the conduct of our business activities, some of which are at preliminary stages and some of which seek an indeterminate amount of damages. We regularly evaluate the status of legal proceedings in which we are involved to assess whether a loss is probable or there is a reasonable possibility that a loss or additional loss may have been incurred to determine if accruals are appropriate. We further evaluate each legal proceeding to assess whether an estimate of possible loss or range of loss can be made if accruals are not appropriate. For certain cases described below, management is unable to provide a meaningful estimate of the possible loss or range of possible loss because, among other reasons, (i) the proceedings are in preliminary stages; (ii) specific damages have not been sought; (iii) damages sought are, in our view, unsupported and/or exaggerated; (iv) there is uncertainty as to the outcome of pending appeals or motions; (v) there are significant factual issues to be resolved; and/or (vi) there are novel legal issues or unsettled legal theories presented. For these cases, however, management does not believe, based on currently available information, that the outcomes of these proceedings will have a material effect on our financial position, results of operations or cash flow. For the matters discussed below, we have not recorded any material accruals as of March 31, 2024 or December 31, 2023.

On September 17, 2019, International Business Machines Corporation (“IBM”) filed a complaint against us in the U.S. District Court for the Central District of California, alleging, among other things, that the Company has infringed and continues to willfully infringe seven patents held by IBM and seeks unspecified damages, including a request that the amount of compensatory damages be trebled, injunctive relief and costs and reasonable attorneys’ fees. On November 8, 2019, we filed a motion to transfer venue and/or to dismiss the complaint. On December 2, 2019, IBM filed an amended complaint, and on December 16, 2019 we filed a renewed motion to transfer venue and/or to dismiss the complaint. The Company’s motion to transfer venue to the U.S. District Court for the Western District of Washington was granted on May 28, 2020. On August 12, 2020, IBM filed its answer to our counterclaims. On September 18, 2020, we filed four Inter Partes Review (“IPR”) petitions before the U.S. Patent and Trial Appeal Board (“PTAB”) seeking the Board’s review of the patentability with respect to three of the patents asserted by IBM in the lawsuit. On March 15, 2021, the PTAB instituted IPR proceedings with respect to two of the three patents for which we filed petitions. On March 22, 2021, the PTAB denied institution with respect to the last of the three patents. On January 22, 2021, the court partially stayed the action with respect to all patents for which we filed an IPR and set forth a motion schedule. On March 8, 2021, IBM filed its second amended complaint. On March 25, 2021, we filed an amended motion for judgment on the pleadings. On July 15, 2021, the court rendered an order in connection with the motion for judgment on the pleadings finding in our favor on two of the four patents on which we filed our motion. On August 31, 2021, the Court ruled that the parties will proceed with respect to the two patents for which it previously denied judgment, and vacated the stay with respect to one of the three patents for which Zillow filed an IPR, which stay was later reinstated by stipulation of the parties on May 18, 2022. On September 23, 2021, IBM filed a notice of appeal with the United States Court of Appeals for the Federal Circuit with respect to the August 31, 2021 judgment entered, which judgment was affirmed by the Federal Circuit on October 17, 2022. On March 3, 2022, the PTAB ruled on Zillow’s two remaining IPRs finding that Zillow was able to prove certain claims unpatentable, and others it was not. On October 28, 2022, the court found one of the two patents upon which the parties were proceeding in this action as invalid, and dismissed IBM’s claim relating to that patent. Following the court’s ruling, on October 28, 2022, the parties filed a joint stipulation with the court seeking a stay of this action, which was granted by the court on November 1, 2022. On November 25, 2022, Zillow filed a motion to join an IPR petition within Ebates Performance Mktg., Inc. d/b/a Rakuten Rewards v. Int’l Bus. Machs. Corp. (“Rakuten IPR”), IPR2022-00646 concerning the final remaining patent in this action, which the court granted on April 20, 2023. On October 11, 2023, the PTAB ruled on the Rakuten IPR finding the claims of the patent asserted against Zillow unpatentable. IBM appealed the PTAB’s decision on November 21, 2023, and cross appeals were filed by Ebates Performance Marketing Inc. on November 21, 2023 and by us on December 15, 2023. On March 20, 2024, IBM voluntarily dismissed all claims filed in this action against Zillow with prejudice, with the exception of those pertaining to the patent asserted within the pending Rakuten IPR appeal. We deny the allegations of any wrongdoing and intend to vigorously defend the claims in the lawsuit. There is a reasonable possibility that a loss may be incurred related to this matter; however, the possible loss or range of loss is not estimable.

22

On July 21, 2020, IBM filed a second action against us in the U.S. District Court for the Western District of Washington, alleging, among other things, that the Company has infringed and continues to willfully infringe five patents held by IBM and seeks unspecified damages. On September 14, 2020, we filed a motion to dismiss the complaint filed in the action, to which IBM responded by the filing of an amended complaint on November 5, 2020. On December 18, 2020, we filed a motion to dismiss IBM’s first amended complaint. On December 23, 2020, the Court issued a written order staying this case in full. On July 23, 2021, we filed an IPR with the PTAB with respect to one patent included in the second lawsuit. On October 6, 2021, the stay of this action was lifted, except for proceedings relating to the one patent for which we filed an IPR. On December 1, 2021, the Court dismissed the fourth claim asserted by IBM in its amended complaint. On December 16, 2021 Zillow filed a motion to dismiss the remaining claims alleged in IBM’s amended complaint. On March 9, 2022, the Court granted Zillow’s motion to dismiss in full, dismissing IBM’s claims related to all the patents asserted by IBM in this action, except for the one patent for which an IPR was still pending. On March 10, 2022, the PTAB rendered its decision denying Zillow’s IPR. On August 1, 2022, IBM filed an appeal of the Court’s ruling with respect to two of the dismissed patents, which ruling was affirmed by the appeals court on January 9, 2024. On March 20, 2024, IBM voluntarily dismissed all claims filed in this action against Zillow with prejudice and the Clerk of Court was directed to close the case.

On November 16, 2021, November 19, 2021 and January 6, 2022, three purported class action lawsuits were filed against us and certain of our executive officers, alleging, among other things, violations of federal securities laws on behalf of a class of those who purchased our stock between August 7, 2020 and November 2, 2021. The three purported class action lawsuits, captioned Barua v. Zillow Group, Inc. et al., Silverberg v. Zillow Group, et al. and Hillier v. Zillow Group, Inc. et al. were brought in the U.S. District Court for the Western District of Washington and were consolidated on February 16, 2022. On May 12, 2022, the plaintiffs filed their amended consolidated complaint which alleges, among other things, that we issued materially false and misleading statements regarding our Zillow Offers business. The complaints seek to recover, among other things, alleged damages sustained by the purported class members as a result of the alleged misconduct. We moved to dismiss the amended consolidated complaint on July 11, 2022, plaintiffs filed their opposition to the motion to dismiss on September 2, 2022, and we filed a reply in support of the motion to dismiss on October 11, 2022. On December 7, 2022, the court rendered its decision granting defendants’ motion to dismiss, in part, and denying the motion, in part. On January 23, 2023, the defendants filed their answer to the consolidated complaint. On March 14, 2024, plaintiffs filed a motion for class certification and we filed our opposition on April 26, 2024. We intend to deny the allegations of wrongdoing and intend to vigorously defend the claims in this consolidated lawsuit. We do not believe that a loss related to this consolidated lawsuit is probable.

On March 10, 2022, May 5, 2022 and July 20, 2022, shareholder derivative suits were filed in the U.S. District Court for the Western District of Washington (“Federal Court”) and on July 25, 2022, a shareholder derivative suit was filed in the Superior Court of the State of Washington, King County (the “2022 State Suit”), against us and certain of our executive officers and directors seeking unspecified damages on behalf of the Company and certain other relief, such as reform to corporate governance practices. The plaintiffs (including the Company as a nominal defendant) allege, among other things, that the defendants breached their fiduciary duties by failing to maintain an effective system of internal controls, which purportedly caused the losses the Company incurred when it decided to wind down Zillow Offers operations. Plaintiffs also allege, among other things, violations of Section 14(a) and Section 20(a) of the Securities Exchange Act of 1934, insider trading and waste of corporate assets. On June 1, 2022 and September 14, 2022, the U.S. District Court for the Western District of Washington issued orders consolidating the three federal derivative suits and staying the consolidated action until further order of the court, which stay was further continued by the Federal Court on September 6, 2023. On September 15, 2022, the Superior Court of the State of Washington entered a temporary stay in the 2022 State Suit. Upon the filing of the defendants’ answer in the related securities class action lawsuit on January 23, 2023, the stay in the 2022 State Suit was lifted. A partial stay was then reentered in the 2022 State Suit, which expired on February 1, 2024. On August 23, 2023 a second shareholder derivative suit was filed in the Superior Court of the State of Washington, King County. The defendants intend to deny the allegations of wrongdoing and vigorously defend the claims in these lawsuits. We do not believe that a loss related to these lawsuits is probable.

In addition to the matters discussed above, from time to time, we are involved in litigation and claims that arise in the ordinary course of business. Although we cannot be certain of the outcome of any such litigation or claims, nor the amount of damages and exposure that we could incur, we currently believe that the final disposition of such matters will not have a material effect on our business, financial position, results of operations or cash flow. Regardless of the outcome, litigation can have an adverse impact on us because of defense and settlement costs, diversion of management resources and other factors.

Indemnifications

In the ordinary course of business, we enter into contractual arrangements under which we agree to provide indemnification of varying scope and terms to business partners and other parties with respect to certain matters. For additional information regarding our indemnifications, see Note 16 in the Notes to the Consolidated Financial Statements in our Annual Report on Form 10-K for the fiscal year ended December 31, 2023.

Item 2. Management’s Discussion and Analysis of Financial Condition and Results of Operations

The following discussion of our financial condition and results of operations should be read in conjunction with our condensed consolidated financial statements and the related notes included elsewhere in this Quarterly Report on Form 10-Q. In addition to historical financial information, the following discussion contains forward-looking statements that reflect our plans, estimates and beliefs. Our actual results may differ materially from those described in or implied by any forward-looking statements. Factors that could cause or contribute to these differences include those discussed below and elsewhere in this Quarterly Report on Form 10-Q, including in the section titled “Note Regarding Forward-Looking Statements,” and those factors discussed in Part I, Item 1A (Risk Factors) of our Annual Report on Form 10-K for the year ended December 31, 2023.

Overview of our Business

Zillow Group is reimagining real estate to make home a reality for more and more people. As the most visited real estate website in the United States, Zillow and its affiliates help people find and get the home they want by connecting them with digital solutions, dedicated partners and agents, and easier buying, selling, financing and renting experiences.

Our portfolio of affiliates, subsidiaries and brands includes Zillow Premier Agent, Zillow Home Loans, our mortgage originations business and affiliate lender, Zillow Rentals, Trulia, StreetEasy, HotPads and Out East. In addition, Zillow Group provides a comprehensive suite of marketing software and technology solutions for the real estate industry, including ShowingTime+, Spruce and Follow Up Boss.

As of March 31, 2024, we had 6,429 employees, compared to 6,263 employees as of December 31, 2023.

Health of Housing Market

Our financial performance is impacted by changes in the health of the housing market, which is impacted, in turn, by general economic conditions. Current market factors have been driven by low housing inventory, fewer new for-sale listings, increases and volatility in mortgage interest rates, as well as home price fluctuations and inflationary conditions. These factors may impact the number of transactions consumers complete using our products and services and on demand for our advertising services. According to industry data from the National Association of REALTORS®, total transaction value increased 4% during the three months ended March 31, 2024 as compared to the three months ended March 31, 2023. Despite the current market factors mentioned above, we continue to invest in our growth pillars. We believe this continued investment has resulted in year over year total revenue results, described below, for the three months ended March 31, 2024 as compared to the same period in the prior year, that exceeded industry performance for the same period. The extent to which market factors impact our results and financial position will depend on future developments, which are uncertain and difficult to predict.

Revenue Overview

Our revenue is classified into four categories: Residential, Rentals, Mortgages and Other.

Residential. Residential revenue includes revenue generated by our Premier Agent and new construction marketplaces, as well as revenue from the sale of advertising and business technology solutions for real estate professionals through StreetEasy for-sale product offerings, ShowingTime+, including Listing Showcase, and upon acquisition on December 8, 2023, Follow Up Boss.

Premier Agent revenue is generated by the sale of advertising services, as well as marketing and technology products and services, to help real estate agents and brokers grow and manage their businesses and brands. We offer these products and services through our Premier Agent program. Premier Agent products, which include the delivery of validated customer connections, or leads, are offered on a share of voice (“market-based pricing”) and pay for performance basis (“Flex”). For our market-based pricing offering, connections are distributed to Premier Agent partners in proportion to their share of voice, or a Premier Agent partner’s share of total advertising purchased in a particular zip code. With the Flex model, Premier Agent partners are provided with validated leads at no initial cost and pay a performance advertising fee only when a real estate transaction is closed with one of the leads, generally within two years.

New construction revenue primarily includes advertising services sold to home builders on a cost per residential community or cost per impression basis.

Revenue generated through ShowingTime+ includes ShowingTime revenue, which is primarily generated by Appointment Center, a software-as-a-service and call center solution allowing real estate agents, brokerages and multiple listing services to efficiently schedule real estate viewing appointments on behalf of their customers. Appointment Center services also

25

include call center specialists who provide scheduling support to customers. ShowingTime+ revenue also includes our dotloop real estate transaction management software-as-a-service solution.

Rentals. Rentals revenue includes advertising and a suite of tools sold to property managers on a cost per lead, lease, listing or impression basis or for a fixed fee for certain advertising packages through both the Zillow and StreetEasy brands. Rentals revenue also includes revenue generated from our rental applications product, through which potential renters can submit applications to multiple properties for a flat service fee.

Mortgages. Mortgages revenue primarily includes revenue generated through mortgage originations and the related sale of mortgages on the secondary market through Zillow Home Loans and from advertising sold to mortgage lenders and other mortgage professionals on a cost per lead basis, including our Custom Quote and Connect services.

Other. Other revenue includes revenue generated primarily by display advertising.

For additional information on our revenue categories, see Note 2 in our Notes to Consolidated Financial Statements in Part II, Item 8 in our Annual Report on Form 10-K for the fiscal year ended December 31, 2023.

Financial Overview

For the three months ended March 31, 2024 and 2023, we generated total revenue of $529 million and $469 million, respectively, an increase of 13%, primarily due to increases in Residential, Rentals and Mortgages revenue.

•Residential revenue increased by $32 million, or 9%, to $393 million, due to increases in residential revenue per visit and the number of visits.

•Rentals revenue increased by $23 million, or 31%, to $97 million, due to an increase in quarterly revenue per average monthly rentals unique visitor.

•Mortgages revenue increased by $5 million, or 19%, to $31 million, driven by an increase in mortgage originations revenue, partially offset by a decrease in Custom Quote and Connect advertising services revenue.

During the three months ended March 31, 2024 and 2023, we generated gross profit of $406 million and $377 million, respectively, an increase of 8%.

Key Metrics

Management has identified visits, unique users and the volume of loans originated through Zillow Home Loans as relevant to investors’ and others’ assessment of our financial condition and results of operations.

Visits

The number of visits is an important metric because it is an indicator of consumers’ level of engagement with our mobile applications, websites and other services. We believe highly engaged consumers are more likely to use our products and services, including Zillow Homes Loans, or be transaction-ready real estate market participants and therefore more sought-after by our Premier Agent partners.

We define a visit as a group of interactions by users with our Zillow, Trulia and StreetEasy mobile applications and websites. A single visit can contain multiple page views and actions, and a single user can open multiple visits across domains, web browsers, desktop or mobile devices. Visits can occur on the same day, or over several days, weeks or months.

Prior to January 1, 2024, we measured visits to Zillow and StreetEasy using the Universal Analytics version of Google Analytics’ traffic measurement platform. Through Universal Analytics, visits to Zillow and StreetEasy ended either: (i) after thirty minutes of user inactivity or at midnight; or (ii) through a campaign change. A visit ends through a campaign change if a visitor arrived via one campaign or source (for example, via a search engine or referring link on a third-party website), left the mobile application or website, and then returned via another campaign or source.

26

Universal Analytics will no longer be offered by Google as of July 1, 2024 and will be replaced by Google Analytics 4. As a result of this change, beginning on January 1, 2024, we measure visits to Zillow using an internal measurement tool, but continue to use Universal Analytics to measure visits to StreetEasy. Trulia continues to measure visits with Adobe Analytics. Visits to Zillow now end after thirty minutes of user inactivity or at midnight. Visits to Trulia end after thirty minutes of user inactivity. Visits to StreetEasy end either: (i) after thirty minutes of user inactivity or at midnight; or (ii) through a campaign change.

We believe the use of an internal measurement tool to measure visits to Zillow will allow us to maintain control over and provide greater insight into our end-to-end data as we enhance our broader long-term analytics strategy, while also becoming less reliant on third-party providers. We have recast prior period visits to conform with the current period measurement methodology. The change in our measurement platform for visits resulted in an approximately 10% decrease in reported visits for the three-month period ended March 31, 2023, primarily driven by the methodology for campaign changes.

The following table presents the number of visits to our mobile applications and websites for the periods presented (in millions, except percentages):

	Three Months Ended March 31,		2023 to 2024 % Change
	2024	2023
Visits	2,316	2,238	3	%

Unique Users

Measuring unique users is important to us because much of our revenue depends in part on our ability to connect home buyers and sellers, renters and individuals with or looking for a mortgage to real estate, rental and mortgage professionals, products and services. Growth in consumer traffic to our mobile applications and websites increases the number of impressions, clicks, connections, leads and other events we can monetize to generate revenue. For example, our revenue depends in part, on users accessing our mobile applications and websites to engage in the sale, purchase, renting and financing of homes, including with Zillow Home Loans, and a significant portion of our Residential revenue, Rentals revenue and Other revenue depend on advertisements being served to users of our mobile applications and websites.

We count a unique user the first time an individual accesses one of our mobile applications using a mobile device during a calendar month and the first time an individual accesses one of our websites using a web browser during a calendar month. If an individual accesses our mobile applications using different mobile devices within a given month, the first instance of access by each such mobile device is counted as a separate unique user. If an individual accesses more than one of our mobile applications within a given month, the first access to each mobile application is counted as a separate unique user. If an individual accesses our websites using different web browsers within a given month, the first access by each such web browser is counted as a separate unique user. If an individual accesses more than one of our websites in a single month, the first access to each website is counted as a separate unique user since unique users are tracked separately for each domain.

Prior to January 1, 2024, we measured unique users for Zillow, StreetEasy and HotPads using Universal Analytics. As discussed above, Universal Analytics will no longer be offered as of July 1, 2024 and will be replaced by Google Analytics 4. As a result of this change, beginning on January 1, 2024, we measure unique users for Zillow using an internal measurement tool, but continue to use Universal Analytics to measure unique users for StreetEasy and HotPads. Trulia continues to measure unique users with Adobe Analytics.

Due to technological limitations, user software settings, or user behavior, our internal measurement tool and Universal Analytics may assign a unique cookie to different instances of access by the same individual to our mobile applications and websites. In such instances, although these tools capture the number of unique users in accordance with the defined methodology, there are inherent limitations in measuring the number of unique individuals accessing our mobile applications and websites.

We believe the use of an internal measurement tool to measure unique users for Zillow will allow us to maintain control over and provide greater insight into our end-to-end data as we enhance our broader long-term analytics strategy, while also becoming less reliant on third-party providers. We have recast prior period unique users to conform to the current period measurement methodology. The change in our measurement platform for unique users resulted in an approximately 3% increase in reported unique users for the three-month period ended March 31, 2023.

27

The following table presents our average monthly unique users for the periods presented (in millions, except percentages):

	Three Months Ended March 31,		2023 to 2024 % Change
	2024	2023
Average monthly unique users	217	217	—	%

Loan Origination Volume

Loan origination volume is an important metric as it is a measure of how successful we are at the origination of mortgage loan products through our mortgage origination business, Zillow Home Loans, which directly impacts our Mortgages revenue. Loan origination volume represents the total value of mortgage loan originations closed through Zillow Home Loans during the period.

The following table presents loan origination volume by purpose and in total for Zillow Home Loans for the periods presented (in millions, except percentages):

	Three Months Ended March 31,				2023 to 2024 % Change
	2024		2023
Purchase loan origination volume	$	601	$	259	132	%
Refinance loan origination volume	4		3		33	%
Total loan origination volume	$	605	$	262	131	%

During the three months ended March 31, 2024, total loan origination volume increased 131%, compared to the three months ended March 31, 2023. This increase in total loan origination volume was primarily driven by the continued growth in Zillow Home Loans purchase loan originations as we prioritize growth in Zillow Home Loans purchase originations.

Results of Operations

Given continued uncertainty surrounding the health of the housing market, interest rate environment and inflationary conditions, financial performance for current and prior periods may not be indicative of future performance.

Three months ended March 31, 2024 compared to three months ended March 31, 2023

Total revenue increased $60 million, or 13%, to $529 million:

•Residential revenue increased $32 million, or 9%. The increase was driven by a 5% increase in Residential revenue per visit to $0.170 for the three months ended March 31, 2024 from $0.161 for the three months ended March 31, 2023, primarily due to the inclusion of revenue from Follow Up Boss, which we acquired in December 2023, in our results for the three months ended March 31, 2024, and continued improvement in our ability to connect high-intent customers to agents. We calculate Residential revenue per visit by dividing the revenue generated by our Residential offerings by the number of visits in the period. Residential revenue was also positively impacted by a 3% increase in the number of visits for the three months ended March 31, 2024, compared to the three months ended March 31, 2023.

•Rentals revenue increased $23 million, or 31%. The increase in Rentals revenue was primarily due to a 41% increase in quarterly revenue per average monthly rentals unique visitor to $3.59 for the three months ended March 31, 2024 as compared to $2.55 for the three months ended March 31, 2023, primarily driven by lower occupancy rates and the corresponding increase in advertising spend from multifamily property managers as well as growth in multifamily property listings, which drove a 46% increase in multifamily rentals revenue. We calculate quarterly revenue per average monthly rentals unique visitor by dividing total Rentals revenue for the period by the average monthly rentals unique visitors for the period and then dividing by the number of quarters in the period. Average monthly rentals unique visitors was 27 million during the three months ended March 31, 2024 and 29 million during the three months ended March 31, 2023. We have estimated average monthly rentals unique visitors using Comscore data, which measures average monthly unique visitors on rental listings on Zillow, Trulia and HotPads mobile apps and websites. We expect Rentals revenue to increase in absolute dollars during the three months ending June 30, 2024, driven by macroeconomic factors, including housing availability and affordability, and decreased rental occupancy rates, as well as continued investment in growing our Rentals business.

•Mortgages revenue increased $5 million, or 19%. This increase was driven by a $13 million increase in mortgage originations revenue, partially offset by a $7 million decrease in Custom Quote and Connect advertising services revenue. The increase in mortgage originations revenue was due to a 131% increase in total originations volume from $262 million for the three months ended March 31, 2023 to $605 million for the three months ended March 31, 2024, primarily driven by continued growth in Zillow Home Loans purchase loan origination volume. The increase in mortgage originations revenue was also attributable to a 17% increase in gain on sale margin. Gain on sale margin represents the net gain on sale of mortgage loans divided by total loan origination volume for the period. Net gain on sale of mortgage loans includes all components related to the origination and sale of mortgage loans, including the net gain on sale of loans into the secondary market, loan origination fees, unrealized gains and losses associated with changes in fair value of IRLCs and mortgage loans held for sale, realized and unrealized gains or losses from derivative financial instruments and the provision for losses relating to representations and warranties. The increase in mortgage originations revenue was partially offset by a $7 million decrease in Custom Quote and Connect advertising services revenue, which decrease was primarily due to a 32% decrease in leads generated from marketing products sold to mortgage professionals. This decrease in leads was primarily driven by a shift in strategic priority as we focus on organic growth of our mortgage origination business.

Adjusted EBITDA

The following table summarizes net loss and Adjusted EBITDA (in millions, except percentages):

									% of Revenue
	Three Months Ended March 31,				2023 to 2024				Three Months Ended March 31,
	2024		2023		$ Change		% Change		2024		2023
Net loss	$	(23)	$	(22)	$	(1)	(5)	%	(4)	%	(5)	%
Adjusted EBITDA	$	125	$	104	$	21	20	%	24	%	22	%

To provide investors with additional information regarding our financial results, we have disclosed Adjusted EBITDA, a non-GAAP financial measure, within this Quarterly Report on Form 10-Q. We have provided a reconciliation below of Adjusted EBITDA to net loss, the most directly comparable U.S. GAAP financial measure.

We have included Adjusted EBITDA in this Quarterly Report on Form 10-Q as it is a key metric used by our management and Board to measure operating performance and trends and to prepare and approve our annual budget. In particular, the exclusion of certain expenses in calculating Adjusted EBITDA facilitates operating performance comparisons on a period-to-period basis.

Our use of Adjusted EBITDA has limitations as an analytical tool, and you should not consider this measure in isolation or as a substitute for analysis of our results as reported under GAAP. Some of these limitations are:

•Adjusted EBITDA does not reflect changes in, or cash requirements for, our working capital needs;

•Adjusted EBITDA does not consider the potentially dilutive impact of share-based compensation;

•Although depreciation and amortization are non-cash charges, the assets being depreciated and amortized may have to be replaced in the future, and Adjusted EBITDA does not reflect cash capital expenditure requirements for such replacements or for new capital expenditures or contractual commitments;

•Adjusted EBITDA does not reflect impairment costs;

•Adjusted EBITDA does not reflect interest expense or other income, net;

•Adjusted EBITDA does not reflect income taxes; and

•Other companies, including companies in our own industry, may calculate Adjusted EBITDA differently from the way we do, limiting its usefulness as a comparative measure.

Because of these limitations, you should consider Adjusted EBITDA alongside other financial performance measures, including various cash-flow metrics, net loss and our other GAAP results.

Cost of Revenue

Cost of revenue consists of expenses related to operating our mobile applications and websites, including associated headcount-related expenses, such as salaries, benefits, bonuses and share-based compensation expense, as well as revenue-sharing costs related to our commercial business relationships, depreciation expense, and costs associated with hosting our mobile applications and websites. Cost of revenue also includes amortization costs related to capitalized website and development activities, amortization of software, amortization of certain intangible assets and other costs to obtain data used to populate our mobile applications and websites, and amortization of certain intangible assets recorded in connection with acquisitions, including developed technology. Cost of revenue also includes credit card fees and ad serving costs paid to third parties, direct costs to provide our rental applications product, and direct costs to originate mortgage loans, including underwriting and processing costs.

Three months ended March 31, 2024 compared to three months ended March 31, 2023

Cost of revenue increased $31 million, or 34%, driven by increases of $17 million in depreciation and amortization expense primarily due to an increase in website development costs, $4 million in mortgage loan processing costs due to increased purchase loan origination volume, $3 million in ad serving costs driven by an increase in revenue, and $2 million in headcount-related expenses, including share-based compensation expense.

Gross Profit

Gross profit is calculated as revenue less cost of revenue. Gross margin is gross profit expressed as a percentage of revenue. Our gross profit has and will continue to be affected by a number of factors, including the mix of revenue from our various product offerings.

Three months ended March 31, 2024 compared to three months ended March 31, 2023

Gross profit increased by $29 million, or 8%, primarily due to an increase in revenue, discussed above. Total gross margin decreased from 80% to 77%.

Sales and Marketing

Sales and marketing expenses consist of advertising costs and other sales expenses related to promotional and marketing activities, headcount-related expenses, including salaries, commissions, benefits, bonuses and share-based compensation expense for sales, sales support, customer support, including the customer connections team and mortgage loan officers and specialists, marketing and public relations employees, depreciation expense and amortization of certain intangible assets recorded in connection with acquisitions, including trade names and trademarks and customer relationships.

31

Three months ended March 31, 2024 compared to three months ended March 31, 2023

Sales and marketing expenses increased $10 million, or 6%, due to an increase of $12 million in headcount-related expenses, including share-based compensation expense, as we continue to invest in human capital to grow our businesses, partially offset by a $3 million decrease in marketing and advertising costs driven by active cost management. We expect sales and marketing expenses to increase in absolute dollars during the three months ending June 30, 2024 as we increase our marketing activities and headcount to support the continued expected growth in our Rentals revenue.

Technology and Development

Technology and development expenses consist of headcount-related expenses, including salaries, benefits, bonuses and share-based compensation expense for individuals engaged in the design, development and testing of our products, mobile applications and websites and the tools and applications that support our products. Technology and development expenses also include equipment and maintenance costs and depreciation expense.

Three months ended March 31, 2024 compared to three months ended March 31, 2023

Technology and development expenses increased $10 million, or 7%, due to increases of $12 million in headcount-related expenses, including share-based compensation expense, as we continue to invest in human capital to grow our businesses, and $2 million in software and hardware costs. These increases were partially offset by a $4 million decrease in third-party professional service fees driven by active cost management.

General and Administrative

General and administrative expenses consist of headcount-related expenses, including salaries, benefits, bonuses and share-based compensation expense for executive, finance, accounting, legal, human resources, recruiting, corporate information technology costs and other administrative support. General and administrative expenses also include legal settlement costs and estimated legal liabilities, legal, accounting and other third-party professional service fees, rent expense, depreciation expense and bad debt expense.

Three months ended March 31, 2024 compared to three months ended March 31, 2023

General and administrative expenses increased $9 million, or 7%, primarily due to increases of $4 million in third-party professional service fees, $3 million in headcount-related expenses, including share-based compensation expense, and $3 million due to the change in fair value of contingent consideration associated with our acquisition of Follow Up Boss. These increases were partially offset by a decrease of $3 million in rent expense primarily driven by cost savings associated with changes in the use of certain office space in our lease portfolio.

Impairment Costs

Impairment costs were $6 million for the three month periods ended March 31, 2024 and 2023 and were associated with changes in the use of certain office space in our lease portfolio.

Income Taxes

We are subject to income taxes in the United States (federal and state) and certain foreign jurisdictions. As of March 31, 2024 and December 31, 2023, we have provided a valuation allowance against our net deferred tax assets that we believe, based on the weight of available evidence, are not more likely than not to be realized. There is a reasonable possibility that within the next several years, sufficient positive evidence will become available to demonstrate that a significant portion of the valuation allowance against our U.S. net deferred tax assets will no longer be required. We have accumulated federal tax losses of approximately $1.4 billion as of December 31, 2023, which are available to reduce future taxable income. We have accumulated state tax losses of approximately $56 million (tax effected) as of December 31, 2023.

Income tax expense was not material for the three months ended March 31, 2024 and 2023.

32

In 2021, the OECD, a global policy forum, released Pillar Two, designed to ensure that multinational groups with consolidated financial statement revenue in excess of €750 million annually pay a minimum 15% tax in each jurisdiction in which they operate. The OECD continues to release guidance and countries are implementing legislation to adopt these rules, which are expected to be effective for accounting periods beginning on or after December 31, 2023. The United States has not yet enacted legislation implementing Pillar Two. We have evaluated the impact of these rules and currently believe they will not have a material impact on our financial position, results of operations or cash flows due to certain transitional safe harbors. We will continue to monitor and refine our assessment as further guidance is made available.

Liquidity and Capital Resources

Our primary sources of liquidity and capital resources are cash flows from operations, debt financing and equity offerings. Our cash requirements consist principally of working capital, general corporate needs and mortgage loan originations. We continue to invest in the development and expansion of our operations using available cash flows from operations. Ongoing investments include, but are not limited to, improvements in our technology platforms, investments in new products and services, and continued investments in sales and marketing. We also use cash flows from operations to service our debt obligations and to repurchase Class A common stock, Class C capital stock, outstanding convertible senior notes or a combination thereof through our Repurchase Authorizations or otherwise.

Sources of Liquidity

As of March 31, 2024 and December 31, 2023, we had cash and cash equivalents, investments and restricted cash of $2.9 billion and $2.8 billion, respectively. Cash and cash equivalents balances consist of operating cash on deposit with financial institutions and money market funds. Investments consist of fixed income securities, which include U.S. government treasury securities, U.S. government agency securities, investment grade corporate securities, and commercial paper. Restricted cash primarily consists of amounts used to fund customer home purchases in our mortgage origination business. Amounts on deposit with third-party financial institutions exceed the Federal Deposit Insurance Corporation and the Securities Investor Protection Corporation insurance limits, as applicable. As of March 31, 2024, Zillow Group and its subsidiaries were in compliance with all debt covenants specified in the facilities described below.

We believe that cash from operations and cash and cash equivalents and investment balances will be sufficient to meet our ongoing operating activities, working capital, capital expenditures, strategic acquisitions and investments and other capital requirements for at least the next 12 months. We believe we will meet longer-term expected future cash requirements and obligations through a combination of cash flows from operations, debt financing and equity offerings, as applicable.

Summarized Cash Flow Information

The following table presents selected cash flow data for the periods presented (in millions, unaudited):

	Three Months Ended March 31,
	2024		2023
Cash Flow Data:
Net cash provided by operating activities	$	80	$	93
Net cash used in investing activities	(204)		(97)
Net cash provided by (used in) financing activities	71		(68)

Cash Flows Provided By Operating Activities

Our operating cash flows result primarily from cash received from real estate professionals, rental professionals, mortgage professionals, builders and brand advertisers, as well as cash received from sales of mortgages originated by Zillow Home Loans. Our primary uses of cash from operating activities include marketing and advertising activities, mortgages funded through Zillow Home Loans and employee compensation and benefits. Additionally, uses of cash from operating activities include costs associated with operating our mobile applications and websites and other general corporate expenditures.

33

For the three months ended March 31, 2024, net cash provided by operating activities was $80 million. This was driven by a net loss of $23 million, adjusted by share-based compensation of $108 million, depreciation and amortization of $56 million, accretion of bond discount of $8 million, impairment costs of $6 million, amortization of contract cost assets of $5 million, amortization of right of use assets of $3 million, and amortization of debt issuance costs of $2 million. Changes in operating assets and liabilities decreased cash provided by operating activities by $70 million. The changes in operating assets and liabilities are primarily related to a $32 million increase in mortgage loans held for sale due to an increase in purchase loan origination volume, a $30 million increase in prepaid expenses and other current assets primarily due to an increase in revenue from products and services billed in arrears, a $13 million decrease in lease liabilities due to contractual lease payments, a $5 million increase in contract cost assets primarily due to capitalized sales commissions, and a $4 million increase in accounts receivable primarily due to an increase in revenue from products and services billed in arrears. These changes were partially offset by a $6 million increase in accounts payable driven by the timing of payments, a $6 million increase in deferred revenue and a $2 million increase in other long-term liabilities.

For the three months ended March 31, 2023, net cash provided by operating activities was $93 million. This was driven by a net loss of $22 million, adjusted by share-based compensation of $103 million, depreciation and amortization of $40 million, accretion of bond discount of $10 million, impairment costs of $6 million, amortization of contract cost assets of $6 million, amortization of right of use assets of $6 million, and other adjustments to reconcile net loss to net cash provided by operating activities of $2 million. Changes in operating assets and liabilities decreased cash provided by operating activities by $39 million. The changes in operating assets and liabilities are primarily related to a $27 million increase in prepaid expenses and other current assets due primarily to an increase in revenue from products and services billed in arrears, an $8 million decrease in lease liabilities due to contractual lease payments, a $7 million increase in mortgage loans held for sale due to an increase in loan origination volume, a $6 million increase in contract cost assets, a $3 million increase in accounts receivable and a $3 million decrease in accrued compensation and benefits. These changes were partially offset by a $10 million increase in accrued expenses and other current liabilities primarily driven by the timing of billings and a $5 million increase in deferred revenue.

Cash Flows Used In Investing Activities

Our primary investing activities include the purchase and sale or maturity of investments and the purchase of property and equipment and intangible assets.

For the three months ended March 31, 2024, net cash used in investing activities was $204 million. This was the result of $158 million of net purchases of investments and $46 million of purchases of property and equipment and intangible assets.

For the three months ended March 31, 2023, net cash used in investing activities was $97 million. This was the result of $57 million of net purchases of investments and $40 million of purchases of property and equipment and intangible assets.

Cash Flows Provided By (Used In) Financing Activities

Our primary financing activities include repurchases of Class A common stock and Class C capital stock, the exercise of employee option awards and repayments of borrowings on the warehouse line of credit and master repurchase agreements related to Zillow Home Loans.

For the three months ended March 31, 2024, net cash provided by financing activities was $71 million, which primarily related to $50 million of proceeds from the exercise of option awards and $30 million of net borrowings on our master repurchase agreements related to Zillow Home Loans, partially offset by $9 million of cash paid for share repurchases.

For the three months ended March 31, 2023, net cash used in financing activities was $68 million, which was primarily related to $86 million of cash paid for share repurchases. The cash outflows were partially offset by $13 million of proceeds from the exercise of option awards and $5 million of net borrowings on our warehouse line of credit and master repurchase agreements related to Zillow Home Loans.

34

Capital Resources

Notes

As of March 31, 2024, we have a total of $1.6 billion aggregate principal amount of Notes outstanding. The Notes are senior unsecured obligations, and interest on the convertible notes is paid semi-annually. The following table summarizes our Notes as of the periods presented (in millions, except interest rates):

					March 31, 2024		December 31, 2023
Maturity Date	Aggregate Principal Amount		Stated Interest Rate		Carrying Value		Carrying Value
September 1, 2026	$	499	1.375	%	$	496	$	496
May 15, 2025	507		2.75	%	505		504
September 1, 2024	608		0.75	%	608		607
Total	$	1,614			$	1,609	$	1,607

We may from time to time seek to redeem, retire or purchase outstanding debt through cash purchases and/or exchanges for cash, shares of stock or a combination of cash and stock, pursuant to the redemption terms of such debt securities, in open market purchases, privately negotiated transactions or otherwise. In particular, the 2024 Notes and 2026 Notes may be redeemed if the last reported sale price of our Class C capital stock exceeds $56.56 per share for a specified period of trading days. To the extent our Class C capital stock price rises above those levels, we may redeem the 2024 Notes and/or 2026 Notes, in which case, we would expect to settle any conversions in cash up to the principal amount and shares of Class C capital stock for any conversion obligation in excess of the principal amount. Such redemptions, repurchases or exchanges, if any, will depend on prevailing market conditions, our liquidity requirements, contractual restrictions and other factors. The amounts involved in any such transactions, individually or in the aggregate, may be material. Refer to Note 7 of our Notes to Condensed Consolidated Financial Statements of this Quarterly Report on Form 10-Q for additional information regarding our Notes, including conversion rates, conversion and redemption dates and the related capped call transactions.

Share Repurchases

The Board has authorized the repurchase of up to $2.5 billion of our Class A common stock, Class C capital stock, outstanding Notes or a combination thereof. During the three months ended March 31, 2024, we repurchased 0.1 million shares of Class A common stock and 0.1 million shares of Class C capital stock at an average price of $45.02 and $45.42 per share, respectively, for an aggregate purchase price of $5 million and $4 million, respectively. As of March 31, 2024, $761 million remained available for future repurchases pursuant to the Repurchase Authorizations, which repurchases decrease our liquidity and capital resources when effected. For additional information on these authorizations, see Notes 11 and 13 of our Notes to Consolidated Financial Statements in Part II, Item 8 of our Annual Report on Form 10-K for the fiscal year ended December 31, 2023.

Credit Facilities

Zillow Home Loans operations impact our liquidity and capital resources as a cash intensive business that funds mortgage loans originated for resale in the secondary market. We primarily use debt financing to fund mortgage loan originations. The following table summarizes our master repurchase agreements as of the periods presented (in millions, except interest rates):

Lender	Maturity Date	Maximum Borrowing Capacity		Outstanding Borrowings at March 31, 2024		Outstanding Borrowings at December 31, 2023		Weighted Average Interest Rate at March 31, 2024
JPMorgan Chase Bank, N.A.	May 30, 2024	100		65		40		7.03	%
UBS AG	October 9, 2024	100		58		45		7.05	%

Refer to Note 7 of our Notes to Condensed Consolidated Financial Statements of this Quarterly Report on Form 10-Q for additional information on Zillow Group’s master repurchase agreements.

Contractual Obligations and Other Commitments

Convertible Senior Notes - Includes the aggregate principal amounts of the Notes due on their contractual maturity dates, as well as the associated coupon interest. As of March 31, 2024, we have an outstanding aggregate principal amount of $1.6 billion, $608 million of which is payable within 12 months. Future interest payments associated with the Notes total $40 million, with $23 million payable within 12 months. Refer to Note 7 of our Notes to Condensed Consolidated Financial Statements in this Quarterly Report on Form 10-Q for maturity dates, stated interest rates and additional information on our Notes.

Credit Facilities - Includes principal amounts due for amounts borrowed under the master repurchase agreements to finance mortgages originated through Zillow Home Loans. Principal amounts under the master repurchase agreements are due when the related mortgage loan is sold to an investor or directly to an agency. As of March 31, 2024, we have outstanding principal amounts of $123 million. Amounts exclude an immaterial amount of estimated interest payments.

Operating Lease Obligations - Our lease portfolio primarily comprises operating leases for our office space. During the three months ended March 31, 2024, there were no material changes to our operating lease obligations disclosed in Note 10 of the Notes to the Consolidated Financial Statements in Part II, Item 8 of our Annual Report on Form 10-K for the fiscal year ended December 31, 2023. Additionally, as of March 31, 2024, we had outstanding letters of credit of approximately $11 million, which secure our lease obligations in connection with certain of the operating leases of our office spaces.

Contingent Consideration - In connection with the acquisition of Follow Up Boss, we are obligated to pay contingent consideration upon the achievement of certain performance metrics over a three-year period. For additional information regarding this contingent consideration, see Note 3 and Note 5 of our Notes to Condensed Consolidated Financial Statements in this Quarterly Report on Form 10-Q.

Purchase Obligations - We have non-cancelable purchase obligations for content related to our mobile applications and websites and certain cloud computing costs. During the three months ended March 31, 2024, there were no material changes to the purchase commitments disclosed in Note 16 of the Notes to the Consolidated Financial Statements in Part II, Item 8 of our Annual Report on Form 10-K for the fiscal year ended December 31, 2023.

Critical Accounting Policies and Estimates

Our condensed consolidated financial statements are prepared in accordance with GAAP. The preparation of these condensed consolidated financial statements requires us to make estimates, judgments and assumptions that affect the reported amounts of assets, liabilities, revenue and expenses and related disclosures. We evaluate our estimates, judgments and assumptions on an ongoing basis. Our estimates are based on historical experience and various other assumptions that we believe to be reasonable under the circumstances. Our actual results could differ from these estimates, and the health of the housing market and the broader economy have introduced significant additional uncertainty with respect to estimates, judgments and assumptions, which may materially impact our estimates. For information on our critical accounting policies and estimates, see Part II Item 7 (Management’s Discussion and Analysis of Financial Condition and Results of Operations) of our Annual Report on Form 10-K for the fiscal year ended December 31, 2023. There have been no material changes to our critical accounting policies and estimates as previously disclosed in our Annual Report on Form 10-K for the fiscal year ended December 31, 2023.

37

Item 3. Quantitative and Qualitative Disclosures About Market Risk

We are exposed to market risks in the ordinary course of our business. These risks primarily consist of fluctuations in interest rates.

Interest Rate Risk

Under our current investment policy, we invest our excess cash in money market funds, U.S. government treasury securities, U.S. government agency securities, investment grade corporate securities and commercial paper. Our current investment policy seeks first to preserve capital, second to provide sufficient liquidity for our operating and capital needs and third to maximize yield without putting our principal at risk.

Our short-term investments are exposed to market risk due to the fluctuation of prevailing interest rates that may reduce the yield on our investments or their fair value. For our investment portfolio, we do not believe an immediate 10% increase in interest rates would have a material effect on the fair market value of our portfolio.

As of March 31, 2024, we had approximately $1.6 billion aggregate principal amount of Notes outstanding with maturities ranging from September 2024 through September 2026. All outstanding Notes bear fixed rates of interest and, therefore, do not expose us to financial statement risk associated with changes in interest rates. The fair values of the Notes change primarily when the market price of our stock fluctuates or interest rates change.

We are also subject to market risk which may impact our mortgage loan origination volume and associated revenue and the net interest margin derived from borrowings under our master repurchase agreements that provide capital for Zillow Home Loans. Market risk occurs in periods where changes in short-term interest rates result in mortgage loans being originated with terms that provide a smaller interest rate spread above the financing terms of our master repurchase agreements, which can negatively impact our results of operations. This risk is primarily mitigated through the expedited sale of our loans. As of March 31, 2024 and December 31, 2023, we had $123 million and $93 million, respectively, of outstanding borrowings on our master repurchase agreements which bear interest at a floating rate based on SOFR plus an applicable margin, as defined by the governing agreements. We manage the interest rate risk associated with our mortgage loan origination services through the use of forward sales of mortgage-backed securities. Assuming no change in the outstanding borrowings on the master repurchase agreements, we estimate that a one percentage point increase in SOFR would not have a material effect on our annual interest expense associated with the master repurchase agreements as of March 31, 2024 and December 31, 2023.

For additional details related to our credit facilities and convertible senior notes, see Note 7 to our Notes to Condensed Consolidated Financial Statements of this Quarterly Report on Form 10-Q.

Inflation Risk

The macroeconomic environment in the United States has experienced, and continues to experience, inflationary pressures. While it is difficult to accurately measure the impact of these inflationary pressures on our business, we believe these effects have been pervasive throughout our business during the past several quarters. In response to ongoing inflationary pressures in the United States, the Federal Reserve has implemented a number of increases to the federal funds rate in recent quarters. Despite inflation stabilizing beginning in the second half of 2023, these federal funds rate increases have impacted other market rates derived from this benchmark rate, including mortgage interest rates. The persistently high mortgage interest rates across the industry relative to recent years has impacted the number of transactions consumers complete using our products and services and the demand for our advertising services and mortgage origination offerings and, in turn, had an adverse impact on our revenue.

If inflationary pressures persist, our costs, in particular labor, marketing and hosting costs, may increase and we may not be able to fully offset such higher costs through price increases. In addition, uncertain or changing economic and market conditions, including inflation or deflation, may continue to affect demand for our products and services and the housing markets in which we operate. Our inability or failure to quickly respond to inflation could harm our business, results of operations and financial condition. We cannot predict the duration or magnitude of these inflationary pressures, or how they may change over time, but we expect to see continued impacts on the residential real estate industry, our customers and our company. Despite these near-term effects, we do not expect these inflationary pressures to have a material impact on our ability to execute our long-term business strategy.

38

Foreign Currency Exchange Risk

We do not believe that foreign currency exchange risk has had a material effect on our business, results of operations or financial condition. As we do not maintain a significant balance of foreign currency, we do not believe an immediate 10% increase or decrease in foreign currency exchange rates relative to the U.S. dollar would have a material effect on our business, results of operations or financial condition.

39

Item 4. Controls and Procedures

Evaluation of Disclosure Controls and Procedures

The Company maintains disclosure controls and procedures (as defined under Rules 13a-15(e) and 15d-15(e) of the Securities Exchange Act of 1934, as amended). Management, under the supervision and with the participation of our Chief Executive Officer and our Chief Financial Officer, evaluated the effectiveness of the Company’s disclosure controls and procedures pursuant to Exchange Act Rule 13a-15(b) as of March 31, 2024. Based on that evaluation, the Chief Executive Officer and the Chief Financial Officer concluded that these disclosure controls and procedures were effective as of March 31, 2024.

Changes in Internal Control Over Financial Reporting

There were no changes in our internal control over financial reporting identified in connection with the evaluation required by Rule 13a-15(d) and 15d-15(d) of the Securities Exchange Act of 1934, as amended, that occurred during the three months ended March 31, 2024 that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

Organization and Description of Business

Organization and Description of Business

Zillow Group is reimagining real estate to make home a reality for more and more people. As the most visited real estate website in the United States, Zillow and its affiliates help people find and get the home they want by connecting them with digital solutions, dedicated partners and agents, and easier buying, selling, financing and renting experiences.

Our portfolio of affiliates, subsidiaries and brands includes Zillow Premier Agent, Zillow Home Loans, our mortgage originations business and affiliate lender, Zillow Rentals, Trulia, StreetEasy, HotPads and Out East. In addition, Zillow Group provides a comprehensive suite of marketing software and technology solutions for the real estate industry, including ShowingTime+, Spruce and Follow Up Boss.

Certain Significant Risks and Uncertainties

We operate in a dynamic industry and, accordingly, can be affected by a variety of factors, which are uncertain and difficult to predict. For example, we believe that changes in any of the following areas could have a significant negative effect on us in terms of our future financial position, results of operations or cash flows: current and future health and stability of the economy and United States residential real estate industry, including changes in inflationary conditions, interest rates, housing availability and affordability, labor shortages and supply chain issues; our ability to manage industry changes, including as a result of certain or future class action lawsuits or government investigations; our ability to manage advertising and product inventory and pricing and maintain relationships with our real estate partners; our ability to comply with current and future rules and requirements promulgated by the National Association of REALTORS®, multiple listing services, or other real estate industry groups or governing bodies, and to maintain or establish relationships with listing and data providers; our investment of resources to pursue strategies and develop new products and services that may not prove effective or that are not attractive for customers and real estate partners or that do not allow us to compete successfully; our ability to operate and grow Zillow Home Loans, our mortgage origination business and affiliate lender, including the ability to obtain or maintain sufficient financing and resell originated mortgages on the secondary market; the duration and impact of natural disasters and other catastrophic events (including public health crises) on our ability to operate, demand for our products or services or general economic conditions; outcomes of legal proceedings; our ability to attract, engage, and retain a highly skilled, remote workforce; protection of Zillow Group’s information and systems against security breaches or disruptions in operations; reliance on third-party services to support critical functions of our business; protection of our brand and intellectual property; and changes in laws or government regulation affecting our business, among other things.

Summary of Significant Accounting Policies

Summary of Significant Accounting Policies

Basis of Presentation

The accompanying condensed consolidated financial statements include Zillow Group, Inc. and its wholly owned subsidiaries. All intercompany balances and transactions have been eliminated in consolidation. These condensed consolidated financial statements have been prepared in conformity with United States GAAP and applicable rules and regulations of the SEC regarding interim financial reporting. Certain information and note disclosures normally included in the financial statements prepared in accordance with GAAP have been condensed or omitted pursuant to such rules and regulations. Accordingly, these interim condensed consolidated financial statements should be read in conjunction with the audited financial statements and accompanying notes included in Zillow Group, Inc.’s Annual Report on Form 10-K for the fiscal year ended December 31, 2023. The condensed consolidated balance sheet as of December 31, 2023, included herein, was derived from the audited financial statements of Zillow Group, Inc. as of that date. Certain reclassifications of prior period amounts have been made to conform to the current period presentation.

The unaudited condensed consolidated interim financial statements, in the opinion of management, reflect all adjustments, consisting only of normal recurring adjustments, necessary to present fairly our financial position as of March 31, 2024 and our results of operations, comprehensive loss, shareholders’ equity, and cash flows for the three month periods ended March 31, 2024 and 2023. The results for the three months ended March 31, 2024 are not necessarily indicative of the results to be expected for the year ending December 31, 2024, for any interim period, or for any other future year.

Use of Estimates

The preparation of financial statements in conformity with GAAP requires management to make certain estimates, judgments and assumptions that affect the reported amounts of assets and liabilities and the related disclosures at the date of the financial statements, as well as the reported amounts of revenue and expenses during the periods presented. On an ongoing basis, we evaluate our estimates, including those related to the accounting for certain revenue offerings, amortization period and recoverability of contract cost assets, website and software development costs, recoverability of long-lived assets and intangible assets, share-based compensation, income taxes, business combinations, including the initial and subsequent fair value measurements of assets (primarily intangible assets), liabilities and contingent consideration, and the recoverability of goodwill, among others. To the extent there are material differences between these estimates, judgments or assumptions and actual results, our financial statements will be affected. The health of the housing market and broader economy have introduced significant additional uncertainty with respect to estimates, judgments and assumptions, which may materially impact the estimates previously listed, among others.

Recently Adopted Accounting Standards

In June 2022, the FASB issued guidance to improve existing measurement and disclosure requirements for equity securities that are subject to a contractual sale restriction. This guidance is effective for interim and annual periods beginning after December 15, 2023 on a prospective basis, with early adoption permitted. We adopted this guidance on January 1, 2024, which did not have a material impact on our financial position, results of operations or cash flows.

Recently Issued Accounting Standards Not Yet Adopted

In November 2023, the FASB issued guidance to improve existing disclosure requirements for segment reporting, primarily through enhanced disclosures about significant segment expenses and new disclosures requirements applicable to entities with a single reportable segment. This guidance is effective for annual periods beginning after December 15, 2023 and interim periods beginning after December 15, 2024, on a retrospective basis. We expect to adopt this guidance for the annual period ending December 31, 2024 and have not yet determined the impact the adoption of this guidance will have on our consolidated financial statements.

In December 2023, the FASB issued guidance to enhance the income tax rate reconciliation disclosure requirements and to provide clarity on disclosure requirements for income taxes. This guidance is effective for annual periods beginning after December 15, 2024, and can be applied on a prospective or retrospective basis, with early adoption permitted. We expect to adopt this guidance for the annual period ending December 31, 2025 using the retrospective approach and have not yet determined the impact the adoption of this guidance will have on our consolidated financial statements.

The fair value measurement of other cash equivalents is based on observable market-based inputs principally derived from or corroborated by observable market data (Level 2).

Short-term investments — The fair value measurement of our short-term investments is based on observable market-based inputs or inputs that are derived principally from or corroborated by observable market data by correlation or other means (Level 2).

Restricted cash — The carrying value of restricted cash approximates fair value due to the short period of time that amounts are held in escrow (Level 1).

Mortgage loans held for sale — The fair value of mortgage loans held for sale is generally calculated by reference to quoted prices in secondary markets for commitments to sell mortgage loans with similar characteristics (Level 2).

Forward contracts — The fair value of mandatory loan sales commitments and derivative instruments such as forward sales of mortgage-backed securities that are utilized as economic hedging instruments is calculated by reference to quoted prices for similar assets (Level 2).

Contingent consideration — In December 2023, Zillow Group acquired Follow Up Boss, a customer relationship management system for real estate professionals, for $399 million in cash, net of cash acquired, and contingent consideration of up to $100 million, payable over a three-year period upon achievement of certain performance metrics. The fair value of the contingent consideration is estimated using a Monte Carlo simulation which considers the probabilities of the achievement of certain performance metrics (Level 3).

The discount rates used in our valuation of contingent consideration are based on our estimated cost of debt and are directly related to the fair value of contingent consideration. An increase in the discount rate, in isolation, would result in a decrease in the fair value measurement. Conversely, a decrease in the discount rate, in isolation, would result in an increase in the fair value measurement. The probabilities of achieving the relevant performance metrics used in our valuation of contingent consideration are directly related to the fair value of contingent consideration, as an increase in the probability, in isolation, would result in an increase in the fair value measurement. Conversely, a decrease in the probability, in isolation, would result in a decrease in the fair value measurement.

During the three months ended March 31, 2024, there were no material changes in the unobservable inputs used in determining the fair value of contingent consideration included in our Annual Report on Form 10-K for the fiscal year ended December 31, 2023.

Interest rate lock commitments — The fair value of IRLCs is calculated by reference to quoted prices in secondary markets for commitments to sell mortgage loans with similar characteristics. Expired commitments are excluded from the fair value measurement. Since not all IRLCs will become closed loans, we adjust our fair value measurements for the estimated amount of IRLCs that will not close. This adjustment is effected through the pull-through rate, which represents the probability that an IRLC will ultimately result in a closed loan. For IRLCs that are canceled or expire, any recorded gain or loss is reversed at the end of the commitment period (Level 3).

The pull-through rate is based on estimated changes in market conditions, loan stage and historical borrower behavior. Pull-through rates are directly related to the fair value of IRLCs as an increase in the pull-through rate, in isolation, would result in an increase in the fair value measurement. Conversely, a decrease in the pull-through rate, in isolation, would result in a decrease in the fair value measurement. Changes in the fair value of IRLCs are included within revenue in our condensed

consolidated statements of operations. The following table presents the range and weighted-average pull-through rates used in determining the fair value of IRLCs as of the dates presented:

	March 31, 2024	December 31, 2023
Range	61% - 100%	45% - 100%
Weighted-average	87%	85%

We manage our interest rate risk related to IRLCs and mortgage loans held for sale through the use of derivative instruments, generally forward contracts on MBSs, which are commitments to either purchase or sell a financial instrument at a future date for a specified price, and mandatory loan commitments, which are an obligation by an investor to buy loans at a specified price within a specified time period. We do not enter into or hold derivatives for trading or speculative purposes, and our derivatives are not designated as hedging instruments. Changes in the fair value of our derivative financial instruments are recognized in revenue in our condensed consolidated statements of operations.

Acquisition of Follow Up Boss

On December 8, 2023, Zillow Group acquired Follow Up Boss, a customer relationship management system for real estate professionals, for $399 million in cash, net of cash acquired, and contingent consideration of up to $100 million in cash, payable over a three-year period upon achievement of certain performance metrics. See Note 3 for additional information regarding the preliminary fair value of contingent consideration. The acquisition is consistent with our strategy to invest in a more integrated software experience for our customers. The acquisition of Follow Up Boss has been accounted for as a business combination, and assets acquired and liabilities assumed were generally recorded at their preliminary estimated fair values, in accordance with the applicable accounting guidance. Goodwill represents the expected synergies from combining the acquired assets and the operations of the acquirer as well as intangible assets that do not qualify for separate recognition. Goodwill recorded in connection with the acquisition is deductible for tax purposes.

The total preliminary purchase price has been allocated to the assets acquired and liabilities assumed, including identifiable intangible assets, based on their preliminarily estimated fair values at the acquisition date, as follows (in millions):

Preliminary purchase price:
Cash	$	403
Contingent consideration	81
Total preliminary purchase price	$	484
Identifiable assets acquired and liabilities assumed:
Cash and cash equivalents	$	4
Goodwill	401
Intangible assets	86
Other assets	1
Deferred revenue	(7)
Other liabilities	(1)
Total preliminary purchase price	$	484

The preliminary estimated fair value of the identifiable intangible assets acquired and associated useful lives consisted of the following (in millions):

	Preliminary Estimated Fair Value		Estimated Weighted-Average Useful Life (in years)
Developed technology	$	50	4
Customer relationships	34		7
Trade names and trademarks	2		7
Total	$	86

Estimated fair values of the identifiable intangible assets acquired were determined by management, based in part on a preliminary valuation performed by an independent third-party valuation specialist. We used an income approach to measure the fair value of the customer relationships intangible asset acquired based on the excess earnings method, whereby the fair value is estimated based upon the present value of cash flows that the applicable asset is expected to generate. We used an income approach to measure the fair value of the developed technology and trade names and trademarks based on the relief-from-royalty method. These fair value measurements were based on Level 3 inputs under the fair value hierarchy.

The purchase price allocation for the Follow Up Boss acquisition is preliminary and subject to change during the measurement period up to one year from the acquisition date. We made an initial allocation of the purchase price at the date of the acquisition based upon information available and our understanding of the estimates used to determine the preliminary fair value of acquired assets, assumed liabilities and contingent consideration. We are in the process of specifically identifying the amounts assigned to certain tangible assets acquired and liabilities assumed and contingent consideration. As of March 31, 2024, the measurement period (not to extend beyond one year) is open for the Follow Up Boss acquisition; therefore, assets acquired, liabilities assumed, and contingent consideration are subject to adjustment until the end of the measurement period.

Acquisition-related costs incurred, which primarily included legal, accounting and other external costs directly related to the acquisition, are included within acquisition-related costs in our consolidated statements of operations and were expensed as incurred.

Unaudited pro forma revenue and earnings information has not been presented as the effects were not material to our condensed consolidated financial statements.

Acquisitions of Aryeo and Spruce

On July 31, 2023, Zillow Group acquired Aryeo, a software company that serves real estate photographers, in exchange for approximately $15 million in cash, net of cash acquired, and 380,259 shares of our Class C capital stock with a value of $20 million, for total consideration of $35 million, net of cash acquired. On September 11, 2023, Zillow Group acquired substantially all of the assets and liabilities of Spruce, a tech-enabled title and escrow platform, in exchange for approximately $19 million in cash, net of cash acquired.

The acquisitions of Aryeo and Spruce have been accounted for as business combinations, and assets acquired and liabilities assumed were recorded at their estimated fair values. Goodwill represents the expected synergies from combining the acquired assets and the operations of the acquirer as well as intangible assets that do not qualify for separate recognition. Goodwill recorded in connection with the acquisition of Aryeo is not deductible for tax purposes, and goodwill recorded in connection with the acquisition of Spruce is deductible for tax purposes.

We are subject to income taxes in the United States (federal and state) and certain foreign jurisdictions. As of March 31, 2024 and December 31, 2023, we have provided a valuation allowance against our net deferred tax assets that we believe, based on the weight of available evidence, are not more likely than not to be realized. We have accumulated federal tax losses of approximately $1.4 billion as of December 31, 2023, which are available to reduce future taxable income. We have accumulated state tax losses of approximately $56 million (tax effected) as of December 31, 2023.

Our income tax expense or benefit for interim periods is determined using an estimate of our annual effective tax rate, adjusted for discrete items, if any, that are taken into account for the relevant period. We update our estimate of the annual effective tax rate on a quarterly basis and make year-to-date adjustments to the tax provision or benefit, as applicable. Our income tax expense (benefit) was not material for the three months ended March 31, 2024 and 2023.

During the three months ended March 31, 2024, there were no material changes to the commitments disclosed in Note 16 in the Notes to the Consolidated Financial Statements included in our Annual Report on Form 10-K for the fiscal year ended December 31, 2023.

Legal Proceedings

We are involved in a number of legal proceedings concerning matters arising in connection with the conduct of our business activities, some of which are at preliminary stages and some of which seek an indeterminate amount of damages. We regularly evaluate the status of legal proceedings in which we are involved to assess whether a loss is probable or there is a reasonable possibility that a loss or additional loss may have been incurred to determine if accruals are appropriate. We further evaluate each legal proceeding to assess whether an estimate of possible loss or range of loss can be made if accruals are not appropriate. For certain cases described below, management is unable to provide a meaningful estimate of the possible loss or range of possible loss because, among other reasons, (i) the proceedings are in preliminary stages; (ii) specific damages have not been sought; (iii) damages sought are, in our view, unsupported and/or exaggerated; (iv) there is uncertainty as to the outcome of pending appeals or motions; (v) there are significant factual issues to be resolved; and/or (vi) there are novel legal issues or unsettled legal theories presented. For these cases, however, management does not believe, based on currently available information, that the outcomes of these proceedings will have a material effect on our financial position, results of operations or cash flow. For the matters discussed below, we have not recorded any material accruals as of March 31, 2024 or December 31, 2023.

On September 17, 2019, International Business Machines Corporation (“IBM”) filed a complaint against us in the U.S. District Court for the Central District of California, alleging, among other things, that the Company has infringed and continues to willfully infringe seven patents held by IBM and seeks unspecified damages, including a request that the amount of compensatory damages be trebled, injunctive relief and costs and reasonable attorneys’ fees. On November 8, 2019, we filed a motion to transfer venue and/or to dismiss the complaint. On December 2, 2019, IBM filed an amended complaint, and on December 16, 2019 we filed a renewed motion to transfer venue and/or to dismiss the complaint. The Company’s motion to transfer venue to the U.S. District Court for the Western District of Washington was granted on May 28, 2020. On August 12, 2020, IBM filed its answer to our counterclaims. On September 18, 2020, we filed four Inter Partes Review (“IPR”) petitions before the U.S. Patent and Trial Appeal Board (“PTAB”) seeking the Board’s review of the patentability with respect to three of the patents asserted by IBM in the lawsuit. On March 15, 2021, the PTAB instituted IPR proceedings with respect to two of the three patents for which we filed petitions. On March 22, 2021, the PTAB denied institution with respect to the last of the three patents. On January 22, 2021, the court partially stayed the action with respect to all patents for which we filed an IPR and set forth a motion schedule. On March 8, 2021, IBM filed its second amended complaint. On March 25, 2021, we filed an amended motion for judgment on the pleadings. On July 15, 2021, the court rendered an order in connection with the motion for judgment on the pleadings finding in our favor on two of the four patents on which we filed our motion. On August 31, 2021, the Court ruled that the parties will proceed with respect to the two patents for which it previously denied judgment, and vacated the stay with respect to one of the three patents for which Zillow filed an IPR, which stay was later reinstated by stipulation of the parties on May 18, 2022. On September 23, 2021, IBM filed a notice of appeal with the United States Court of Appeals for the Federal Circuit with respect to the August 31, 2021 judgment entered, which judgment was affirmed by the Federal Circuit on October 17, 2022. On March 3, 2022, the PTAB ruled on Zillow’s two remaining IPRs finding that Zillow was able to prove certain claims unpatentable, and others it was not. On October 28, 2022, the court found one of the two patents upon which the parties were proceeding in this action as invalid, and dismissed IBM’s claim relating to that patent. Following the court’s ruling, on October 28, 2022, the parties filed a joint stipulation with the court seeking a stay of this action, which was granted by the court on November 1, 2022. On November 25, 2022, Zillow filed a motion to join an IPR petition within Ebates Performance Mktg., Inc. d/b/a Rakuten Rewards v. Int’l Bus. Machs. Corp. (“Rakuten IPR”), IPR2022-00646 concerning the final remaining patent in this action, which the court granted on April 20, 2023. On October 11, 2023, the PTAB ruled on the Rakuten IPR finding the claims of the patent asserted against Zillow unpatentable. IBM appealed the PTAB’s decision on November 21, 2023, and cross appeals were filed by Ebates Performance Marketing Inc. on November 21, 2023 and by us on December 15, 2023. On March 20, 2024, IBM voluntarily dismissed all claims filed in this action against Zillow with prejudice, with the exception of those pertaining to the patent asserted within the pending Rakuten IPR appeal. We deny the allegations of any wrongdoing and intend to vigorously defend the claims in the lawsuit. There is a reasonable possibility that a loss may be incurred related to this matter; however, the possible loss or range of loss is not estimable.

On July 21, 2020, IBM filed a second action against us in the U.S. District Court for the Western District of Washington, alleging, among other things, that the Company has infringed and continues to willfully infringe five patents held by IBM and seeks unspecified damages. On September 14, 2020, we filed a motion to dismiss the complaint filed in the action, to which IBM responded by the filing of an amended complaint on November 5, 2020. On December 18, 2020, we filed a motion to dismiss IBM’s first amended complaint. On December 23, 2020, the Court issued a written order staying this case in full. On July 23, 2021, we filed an IPR with the PTAB with respect to one patent included in the second lawsuit. On October 6, 2021, the stay of this action was lifted, except for proceedings relating to the one patent for which we filed an IPR. On December 1, 2021, the Court dismissed the fourth claim asserted by IBM in its amended complaint. On December 16, 2021 Zillow filed a motion to dismiss the remaining claims alleged in IBM’s amended complaint. On March 9, 2022, the Court granted Zillow’s motion to dismiss in full, dismissing IBM’s claims related to all the patents asserted by IBM in this action, except for the one patent for which an IPR was still pending. On March 10, 2022, the PTAB rendered its decision denying Zillow’s IPR. On August 1, 2022, IBM filed an appeal of the Court’s ruling with respect to two of the dismissed patents, which ruling was affirmed by the appeals court on January 9, 2024. On March 20, 2024, IBM voluntarily dismissed all claims filed in this action against Zillow with prejudice and the Clerk of Court was directed to close the case.

On November 16, 2021, November 19, 2021 and January 6, 2022, three purported class action lawsuits were filed against us and certain of our executive officers, alleging, among other things, violations of federal securities laws on behalf of a class of those who purchased our stock between August 7, 2020 and November 2, 2021. The three purported class action lawsuits, captioned Barua v. Zillow Group, Inc. et al., Silverberg v. Zillow Group, et al. and Hillier v. Zillow Group, Inc. et al. were brought in the U.S. District Court for the Western District of Washington and were consolidated on February 16, 2022. On May 12, 2022, the plaintiffs filed their amended consolidated complaint which alleges, among other things, that we issued materially false and misleading statements regarding our Zillow Offers business. The complaints seek to recover, among other things, alleged damages sustained by the purported class members as a result of the alleged misconduct. We moved to dismiss the amended consolidated complaint on July 11, 2022, plaintiffs filed their opposition to the motion to dismiss on September 2, 2022, and we filed a reply in support of the motion to dismiss on October 11, 2022. On December 7, 2022, the court rendered its decision granting defendants’ motion to dismiss, in part, and denying the motion, in part. On January 23, 2023, the defendants filed their answer to the consolidated complaint. On March 14, 2024, plaintiffs filed a motion for class certification and we filed our opposition on April 26, 2024. We intend to deny the allegations of wrongdoing and intend to vigorously defend the claims in this consolidated lawsuit. We do not believe that a loss related to this consolidated lawsuit is probable.

On March 10, 2022, May 5, 2022 and July 20, 2022, shareholder derivative suits were filed in the U.S. District Court for the Western District of Washington (“Federal Court”) and on July 25, 2022, a shareholder derivative suit was filed in the Superior Court of the State of Washington, King County (the “2022 State Suit”), against us and certain of our executive officers and directors seeking unspecified damages on behalf of the Company and certain other relief, such as reform to corporate governance practices. The plaintiffs (including the Company as a nominal defendant) allege, among other things, that the defendants breached their fiduciary duties by failing to maintain an effective system of internal controls, which purportedly caused the losses the Company incurred when it decided to wind down Zillow Offers operations. Plaintiffs also allege, among other things, violations of Section 14(a) and Section 20(a) of the Securities Exchange Act of 1934, insider trading and waste of corporate assets. On June 1, 2022 and September 14, 2022, the U.S. District Court for the Western District of Washington issued orders consolidating the three federal derivative suits and staying the consolidated action until further order of the court, which stay was further continued by the Federal Court on September 6, 2023. On September 15, 2022, the Superior Court of the State of Washington entered a temporary stay in the 2022 State Suit. Upon the filing of the defendants’ answer in the related securities class action lawsuit on January 23, 2023, the stay in the 2022 State Suit was lifted. A partial stay was then reentered in the 2022 State Suit, which expired on February 1, 2024. On August 23, 2023 a second shareholder derivative suit was filed in the Superior Court of the State of Washington, King County. The defendants intend to deny the allegations of wrongdoing and vigorously defend the claims in these lawsuits. We do not believe that a loss related to these lawsuits is probable.

In addition to the matters discussed above, from time to time, we are involved in litigation and claims that arise in the ordinary course of business. Although we cannot be certain of the outcome of any such litigation or claims, nor the amount of damages and exposure that we could incur, we currently believe that the final disposition of such matters will not have a material effect on our business, financial position, results of operations or cash flow. Regardless of the outcome, litigation can have an adverse impact on us because of defense and settlement costs, diversion of management resources and other factors.

Indemnifications

In the ordinary course of business, we enter into contractual arrangements under which we agree to provide indemnification of varying scope and terms to business partners and other parties with respect to certain matters. For additional information regarding our indemnifications, see Note 16 in the Notes to the Consolidated Financial Statements in our Annual Report on Form 10-K for the fiscal year ended December 31, 2023.

Accounting Policies [Abstract]

Basis of Presentation

Basis of Presentation

The accompanying condensed consolidated financial statements include Zillow Group, Inc. and its wholly owned subsidiaries. All intercompany balances and transactions have been eliminated in consolidation. These condensed consolidated financial statements have been prepared in conformity with United States GAAP and applicable rules and regulations of the SEC regarding interim financial reporting. Certain information and note disclosures normally included in the financial statements prepared in accordance with GAAP have been condensed or omitted pursuant to such rules and regulations. Accordingly, these interim condensed consolidated financial statements should be read in conjunction with the audited financial statements and accompanying notes included in Zillow Group, Inc.’s Annual Report on Form 10-K for the fiscal year ended December 31, 2023. The condensed consolidated balance sheet as of December 31, 2023, included herein, was derived from the audited financial statements of Zillow Group, Inc. as of that date. Certain reclassifications of prior period amounts have been made to conform to the current period presentation.

The unaudited condensed consolidated interim financial statements, in the opinion of management, reflect all adjustments, consisting only of normal recurring adjustments, necessary to present fairly our financial position as of March 31, 2024 and our results of operations, comprehensive loss, shareholders’ equity, and cash flows for the three month periods ended March 31, 2024 and 2023. The results for the three months ended March 31, 2024 are not necessarily indicative of the results to be expected for the year ending December 31, 2024, for any interim period, or for any other future year.

Use of Estimates

Use of Estimates

The preparation of financial statements in conformity with GAAP requires management to make certain estimates, judgments and assumptions that affect the reported amounts of assets and liabilities and the related disclosures at the date of the financial statements, as well as the reported amounts of revenue and expenses during the periods presented. On an ongoing basis, we evaluate our estimates, including those related to the accounting for certain revenue offerings, amortization period and recoverability of contract cost assets, website and software development costs, recoverability of long-lived assets and intangible assets, share-based compensation, income taxes, business combinations, including the initial and subsequent fair value measurements of assets (primarily intangible assets), liabilities and contingent consideration, and the recoverability of goodwill, among others. To the extent there are material differences between these estimates, judgments or assumptions and actual results, our financial statements will be affected. The health of the housing market and broader economy have introduced significant additional uncertainty with respect to estimates, judgments and assumptions, which may materially impact the estimates previously listed, among others.

Recently Adopted Accounting Standards and Recently Issued Accounting Standards Not Yet Adopted

Recently Adopted Accounting Standards

In June 2022, the FASB issued guidance to improve existing measurement and disclosure requirements for equity securities that are subject to a contractual sale restriction. This guidance is effective for interim and annual periods beginning after December 15, 2023 on a prospective basis, with early adoption permitted. We adopted this guidance on January 1, 2024, which did not have a material impact on our financial position, results of operations or cash flows.

Recently Issued Accounting Standards Not Yet Adopted

In November 2023, the FASB issued guidance to improve existing disclosure requirements for segment reporting, primarily through enhanced disclosures about significant segment expenses and new disclosures requirements applicable to entities with a single reportable segment. This guidance is effective for annual periods beginning after December 15, 2023 and interim periods beginning after December 15, 2024, on a retrospective basis. We expect to adopt this guidance for the annual period ending December 31, 2024 and have not yet determined the impact the adoption of this guidance will have on our consolidated financial statements.

In December 2023, the FASB issued guidance to enhance the income tax rate reconciliation disclosure requirements and to provide clarity on disclosure requirements for income taxes. This guidance is effective for annual periods beginning after December 15, 2024, and can be applied on a prospective or retrospective basis, with early adoption permitted. We expect to adopt this guidance for the annual period ending December 31, 2025 using the retrospective approach and have not yet determined the impact the adoption of this guidance will have on our consolidated financial statements.

Fair Value Measurements

We apply the following methods and assumptions in estimating our fair value measurements:

Cash equivalents — The fair value measurement of money market funds is based on quoted market prices in active markets (Level 1). The fair value measurement of other cash equivalents is based on observable market-based inputs principally derived from or corroborated by observable market data (Level 2).

Short-term investments — The fair value measurement of our short-term investments is based on observable market-based inputs or inputs that are derived principally from or corroborated by observable market data by correlation or other means (Level 2).

Restricted cash — The carrying value of restricted cash approximates fair value due to the short period of time that amounts are held in escrow (Level 1).

Mortgage loans held for sale — The fair value of mortgage loans held for sale is generally calculated by reference to quoted prices in secondary markets for commitments to sell mortgage loans with similar characteristics (Level 2).

Forward contracts — The fair value of mandatory loan sales commitments and derivative instruments such as forward sales of mortgage-backed securities that are utilized as economic hedging instruments is calculated by reference to quoted prices for similar assets (Level 2).

Contingent consideration — In December 2023, Zillow Group acquired Follow Up Boss, a customer relationship management system for real estate professionals, for $399 million in cash, net of cash acquired, and contingent consideration of up to $100 million, payable over a three-year period upon achievement of certain performance metrics. The fair value of the contingent consideration is estimated using a Monte Carlo simulation which considers the probabilities of the achievement of certain performance metrics (Level 3).

The discount rates used in our valuation of contingent consideration are based on our estimated cost of debt and are directly related to the fair value of contingent consideration. An increase in the discount rate, in isolation, would result in a decrease in the fair value measurement. Conversely, a decrease in the discount rate, in isolation, would result in an increase in the fair value measurement. The probabilities of achieving the relevant performance metrics used in our valuation of contingent consideration are directly related to the fair value of contingent consideration, as an increase in the probability, in isolation, would result in an increase in the fair value measurement. Conversely, a decrease in the probability, in isolation, would result in a decrease in the fair value measurement.

During the three months ended March 31, 2024, there were no material changes in the unobservable inputs used in determining the fair value of contingent consideration included in our Annual Report on Form 10-K for the fiscal year ended December 31, 2023.

Interest rate lock commitments — The fair value of IRLCs is calculated by reference to quoted prices in secondary markets for commitments to sell mortgage loans with similar characteristics. Expired commitments are excluded from the fair value measurement. Since not all IRLCs will become closed loans, we adjust our fair value measurements for the estimated amount of IRLCs that will not close. This adjustment is effected through the pull-through rate, which represents the probability that an IRLC will ultimately result in a closed loan. For IRLCs that are canceled or expire, any recorded gain or loss is reversed at the end of the commitment period (Level 3).

The pull-through rate is based on estimated changes in market conditions, loan stage and historical borrower behavior. Pull-through rates are directly related to the fair value of IRLCs as an increase in the pull-through rate, in isolation, would result in an increase in the fair value measurement. Conversely, a decrease in the pull-through rate, in isolation, would result in a decrease in the fair value measurement. Changes in the fair value of IRLCs are included within revenue in our condensed

consolidated statements of operations. The following table presents the range and weighted-average pull-through rates used in determining the fair value of IRLCs as of the dates presented:

	March 31, 2024	December 31, 2023
Range	61% - 100%	45% - 100%
