April 16, 2024 

Dear Fellow Shareholders,  

Zillow’s mission is to give people the power to unlock life’s next chapter so we can help make 

home a reality for more and more people.  Since our founding, we have given customers the 

tools and insights they need to navigate one of the most important, emotional, and 

complicated transactions of their lives.   

Over the years, we’ve “turned on the lights” in real estate by building engaging and practical 

products and services designed to empower consumers with data and information, 

transforming a previously opaque marketplace into the more transparent one we experience 

today.  But “turning on the lights” only got Zillow and our large audience so far.  To effect real 

change for consumers and open up a much larger opportunity, we needed to focus on the 

moving experience from start to finish and work to transform the transaction itself.   

In February 2022, we published an Investor Strategy Deck1 that detailed the opportunity we saw 

to serve more mover-consumers in our funnel through the concept of the “housing super app” 

— an integrated digital experience that connects the fragmented pieces of the moving 

process and brings them together on one platform: Zillow.  We see this strategy as a 

continuation of what we’ve been working on since we founded the company — a commitment 

to transform the way people buy, sell, finance, and rent homes. 

2022 was about defining our go-forward strategy, orienting our company and our business 

around our shared vision, and aligning our organizational structure to set us up for success on 

our growth strategy.  2023 was about making progress on our initiatives through product 

launches and market rollouts, setting us up to expand and scale in 2024 and 2025. 

In February 2024, we published an updated Investor Strategy Deck2 (2024 Investor Strategy 

Deck) that details what we have accomplished to date as we empower consumers by

delivering real estate data and education, a suite of Zillow-owned solutions, and a network of 

best-in-class partners, at their fingertips.  Zillow, the housing super app, is now the container 

into which we will continually place new features and services that work together seamlessly 

to solve real customer and agent pain points in their moves.   

In our 2024 Investor Strategy Deck, we also introduced a new, refined way to size our 

opportunity — an estimated $30 billion accessible total addressable market (TAM) of high-

intent customers who we believe are already raising their hands in the Zillow funnel3.  In 2023, 

we captured only $1.5 billion of that $30 billion accessible TAM, which represents our full-year 

2023 Residential and Mortgages revenue as reported.  Our opportunity is to take our current 

small slice of a large TAM and grow it into a much bigger piece of the pie.   

We believe we have many years of growth ahead into that $30 billion revenue TAM, bolstered 

by our position as one of the largest internet brands in the United States.  Based on survey 

data, we estimate that 70% of all consumers who transact in residential real estate visit and 

use Zillow.  Additionally, our data indicates Zillow has more than 60%4 unaided brand 

awareness among buyers, which is rarefied air for a brand to achieve in any category.  Our 

brand strength is also evident in Zillow’s traffic composition, with about 80%5 being organic, 

and in our app usage, which is more than three times that of our nearest competitor6.  

Growth Strategy 

We’re investing across five for-sale growth pillars: touring, financing, seller solutions, enhancing 

our partner network, and integrating our services.  We’ve also added rentals as an additional 

growth pillar.  These growth pillars serve as a roadmap to achieve our goals to grow our 

revenue as we aim to grow customer transaction share from 3% to 6% by the end of 20257. 

Touring —  When a customer who’s been coveting a home on Zillow raises their hand to tour it 

in real life, we believe it’s a strong signal of serious intent to transact.  Our real-time touring 

product, powered by ShowingTime, is meaningfully improving our ability to connect these 

higher-intent customers to our Premier Agent partners.  We ended 2023 with real-time tours

delivering approximately 10% of our total Premier Agent partner connections.  This is driving a 

better customer and agent experience, with less friction, as we see increased successful 

connections and more customers working with Premier Agent partners. 

Financing —  Our industry surveys indicate that approximately 40%8 of all homebuyers start 

their journey by shopping for a mortgage, and 80%9 of those buyers don’t yet have an agent.  

Knowing that almost all of these mortgage seekers use Zillow to shop for a home positions us 

well as we build a substantial direct-to-consumer purchase mortgage origination business 

within Zillow Home Loans10 that is seamlessly integrated with our extensive Premier Agent 

partner network.  

Our integration efforts are driving purchase mortgage origination volume growth.  In our 

original four enhanced markets (Atlanta, Phoenix, Raleigh, Denver), we saw our customer 

adoption rates climb from 6% to 15% over the course of 202311.  Additionally, the percentage of 

Zillow Home Loans purchase mortgages in which a customer works with a Premier Agent 

partner increased from 23% in Q1 2023 to 53% in Q4 2023.  

Seller Solutions —  In 2023, we expanded our TAM by introducing new seller solutions, most 

notably Listing Showcase12.  This product elevates agents’ brand presence on Zillow and helps 

them win more listings.  Listing Showcase also improves the shopper experience with our 

homegrown AI-powered rich media and floor plan technology.  This is a unique differentiator 

in the marketplace and a considerable benefit to buyer engagement and experience.  

We are in the early days of this product, having launched it in Q3 2023, and we are seeing 

significant demand from listing agents and significant engagement from consumers.  Our 

data indicates that Listing Showcase listings on Zillow receive 75% more page views, 68% more 

saves, and 75% more shares13.  We are actively rolling out Listing Showcase nationwide.

preceding six-month average.

Enhanced Partner Network —  We help the best agents provide better service to more of our 

shared customers to grow their businesses and ours in several ways:  

●  First, we’re increasing the number of our enhanced market partners as we plan to 

expand from nine enhanced markets to 40 enhanced markets by the end of 2024.   

●  Second, we’re working to deliver the integrated experience between Zillow Home Loans 

and our Premier Agent partners.  We’re seeing strong progress already, with one in two 

Premier Agent partners in our enhanced markets introducing their customers to Zillow 

Home Loans at the end of 2023, up from one in five at the end of 2022.  

● 

Last, we are excited to accelerate improvements to Follow Up Boss, which we acquired 

in December 2023, and make it available to more agents to increase conversion.  

Follow Up Boss is an industry-leading CRM (customer relationship management) 

system that gives top-performing real estate professionals a central hub to organize 

and engage customers, close deals, and build their teams.  With the power of Follow Up 

Boss, our Premier Agent partners will be better equipped to deliver the best possible 

customer experiences while growing their businesses. 

Integrating our Services —  This growth pillar involves pulling together consumer, agent, and 

loan officer technology, and integrating them into the housing super app.  As evidenced by 

our performance in our two earliest enhanced markets, Phoenix and Atlanta, our integrated 

strategy is working to drive customer transaction share gains.  From the beginning of 2022 to 

the end of 2023, our customer transaction share in these enhanced markets has nearly 

doubled14.  Additionally, across our entire set of nine enhanced markets at the end of 2023, we 

are seeing consistent outperformance in connections growth versus the industry15. 

Rentals —  Providing our customers with optionality is as important as ever in a challenging 

housing market, especially considering that nearly every homebuyer starts out as a renter.  We 

now have the largest audience16 of renters in the market, with limited marketing spend to date.  

As the traffic leader, we’ve been able to grow the number of multifamily properties on our 

apps and sites, which has accelerated our multifamily revenue from 14% year-over-year 

growth in Q4 2022 to 52% in Q4 2023.

Industry 

We are monitoring the impact of potential changes within the industry as a result of numerous 

lawsuits.  Zillow is not a named party in the various lawsuits regarding agent compensation, 

and we remain confident in our ability to meaningfully grow our company over time.   

We believe all roads lead to Zillow, and we’re well-positioned to thrive in any weather. 

We continue to advocate for what we believe is best for consumers and the real estate 

industry as a whole.  In November 2023, we outlined the marketplace principles that underlie 

Zillow’s position — access, representation, and compensation.   

●  We believe in a real estate marketplace that is transparent and fair, in which 

consumers and agents have easy and equitable access to listings and information.  

●  We believe buyers and sellers deserve independent representation. 

●  We believe agents should be compensated fairly and that consumers should be well-

informed of agent compensation as well as their right to negotiate. 

We recently elaborated on these views on a new web page — advocacy.zillowgroup.com — 

that outlines how we are working to elevate industry standards on consumers’ behalf.   

Looking Ahead 

It has been a busy and exciting two years as we’ve been building and investing in these 

growth pillars, adding to our Zillow housing super app experience.  We are looking forward to 

continued growth in the years ahead as we solve customer pain points to build a better, 

integrated real estate transaction experience.  

Thank you for your continued support.

Factors that may contribute to such differences include, but are not limited 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 a

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 party; our ability to continue to innovate and compete 
successfully against our existing or future competitors 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

actions, which may include lawsuits or investigations in 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; actual or anticipated fluctuations in 
quarterly and annual results of operations and financial position; and the assumptions, estimates and internal or 
third-party data that we use to calculate business, performance and operating metrics. The foregoing list of risks and 
uncertainties is illustrative but not exhaustive. For more information about potential factors that could affect Zillow 
Group’s business and financial results, please review the “Risk Factors” described in Zillow Group’s SEC filings. Except 
as may be required by law, Zillow Group does not intend and undertakes no duty to update this information to reflect 
future events or circumstances. 

Use of Operating Metrics:  Zillow Group reviews a number of operating metrics to evaluate its business, measure 
performance, identify trends, formulate business plans, and make strategic decisions. This letter includes Customer 
Transaction Share as a percentage of total residential real estate transactions. Zillow Group uses these operating 
metrics on a periodic basis to evaluate and provide investors with insight into the performance of Zillow Group’s 
transaction-based lines of business, which currently include Premier Agent, Listing Showcase, seller solutions, Zillow 
Home Loans and Listing Showcase. 

Customer Transactions: Unless otherwise indicated, Zillow Group calculates “Customer Transactions” as each unique 
home purchase or sale transaction in which the buyer or seller uses Zillow Home Loans, Listing Showcase, and/or 
involves a Premier Agent or seller solutions partner with whom the buyer or seller connected through Zillow Group. In 
particular: (1) For Premier Agent and seller solutions partners, Zillow Group uses an internal approximation of the 
number of buy- and/or sell-side transactions, as applicable, that involve a Premier Agent or seller solutions partner 
with whom the buyer or seller connected through Zillow Group. Because of the challenges associated with measuring 
the conversion of connections to transactions outside of our Premier Agent Flex and our seller solutions programs, 
including reliance on the availability and quality of public records and data, these estimates may be inaccurate. (2) 

6 

 
 
 
For Zillow Home Loans, Zillow Group counts each unique purchase transaction in which the buyer uses Zillow Home 
Loans. (3) For Listing Showcase, Zillow Group counts each unique sale transaction in which the listing agent or seller 
uses Listing Showcase. 

Customer Transaction Share: Unless otherwise indicated, “Customer Transaction Share” is Customer Transactions 
divided by the number of total residential real estate transactions, for the period presented.     

This letter contains estimates and other statistical data made by independent parties and by Zillow Group relating to 
market size, the housing market, connections, engagement, transactions, growth and other data about Zillow Group's 
industry and performance. These data involve a number of assumptions and limitations, which may significantly 
impact their accuracy, and you are cautioned not to give undue weight to such estimates. Projections, assumptions 
and estimates of future performance are necessarily subject to a high degree of uncertainty and risk.

Item 1. Business. 

Overview 

PART I  

We are 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. Hundreds of millions of 
people visit our mobile applications and websites every month to begin their journey. 

At the core of Zillow is our living database of approximately 160 million U.S. homes and our differentiated content, most 

notably the Zestimate, our patented proprietary automated valuation model through which we provide home value estimates. 
With the launch of the Zestimate feature in 2006, we introduced important transparency to residential real estate in order to 
empower consumers to make better decisions. During 2023, our Zestimate feature had a median error rate of 2.3% for homes 
listed for sale and 7.4% for off-market homes. We believe our data and content has helped the Zillow brand become 
synonymous with residential real estate with Zillow being searched more than the term “real estate” in the United States. 

Our vision of a “housing super app” is to help customers across all their real estate needs serving as one ecosystem of 
connected solutions for all the tasks and services related to moving. We are focused on continually improving our customer 
funnel, capturing customer demand and connecting that demand to our partner network. We believe this focus allows us to build 
closer relationships with our customers to help them find and move into the places they call home, which is at the core of our 
mission. We also believe the path to realizing our “housing super app” vision involves executing on product initiatives across 
six growth pillars: 

• 

Touring – Make it easier for high-intent customers to take in-person tours and connect with our partner agents 

•  Financing – Prepare customers to be transaction-ready with financing early in their home buying journey 

•  Expanding seller services – Invest in tech-enabled solutions and services to make selling homes easier for sellers and 

listing agents 

•  Enhancing our partner network – Help the best agents to better serve more customers and grow their businesses 

•  Rentals – Build a comprehensive rental marketplace for customers and property managers 

• 

Integrating our services – Bring our engagement, products and services together to drive more transactions and more 
revenue per customer transaction 

We continue to operate in a challenging macro housing environment where rising mortgage rates and low housing supply 
have led to affordability challenges for many potential buyers. Many potential sellers have postponed or forgone opportunities 
to sell, choosing instead to hold onto their existing lower-rate mortgages, limiting for-sale housing supply as a result. However, 
while this shortfall of for-sale inventory has limited sales volume, prices have continued to rise as competition for the relatively 
few available for-sale homes remains firm. These macroeconomic factors and their impact on the residential real estate market 
have affected our business and influenced the resources we use to direct our operations. 

In the fourth quarter of 2021, the Board of Directors of Zillow Group made the determination to wind down Zillow 
Offers, our iBuying business which purchased and sold homes directly in markets across the United States. The wind down was 
completed in the third quarter of 2022, which resulted in approximately a 25% reduction of Zillow Group’s workforce. The 
financial results of Zillow Offers have been presented in the accompanying consolidated financial statements as discontinued 
operations. For additional information, see Note 3 in our Notes to the Consolidated Financial Statements in Part II, Item 8 of 
this Annual Report on Form 10-K. 

Beginning in 2023, our chief executive officer, who acts as the chief operating decision maker, began to manage our 
business, make operating decisions, and evaluate operating performance on the basis of the company as a whole, instead of on a 

3 

 
 
segment basis as he did prior to 2023. Accordingly, this change led to revisions to the nature and substance of information 
regularly provided to and used by the chief operating decision maker, and served to align our reported results with our ongoing 
growth strategy and our intent to provide integrated customer solutions for all tasks and services related to facilitating real 
estate transactions. As a result, beginning in the first quarter of 2023, we began to report our financial results as a single 
reportable segment. 

In the fourth quarter of 2023, we closed the acquisition of Follow Up Boss, a customer relationship management system 

that gives real estate professionals a central hub to organize and engage customers, close deals, and build their teams. Follow 
Up Boss has been a key integration partner of ours for several years, and the product is widely utilized by the broader real estate 
industry and many of our Premier Agent partners. For additional information, see Note 7 in our Notes to the Consolidated 
Financial Statements in Part II, Item 8 of this Annual Report on Form 10-K. 

Customer Offerings 

To deliver on our mission, we strive to provide a seamless, integrated transaction experience for movers through Zillow, 
our network of trusted partners, our affiliated brands, and through a comprehensive suite of marketing software and technology 
solutions for the real estate industry, including Spruce, Mortech, New Home Feed, ShowingTime+ and Follow Up Boss. We do 
this through a range of services designed to help our customers in whatever stage of the housing journey they may be in. This 
typically includes the need for multiple services simultaneously. Approximately 70% of sellers are also buying at the same time, 
and among renters with plans to move within the next year, 43% plan to buy their next home1. 

Our services are primarily designed for the following: 

For Buyers, Sellers and Partners – When a buyer is ready to begin their home buying journey, we offer a variety of 
options depending on where they choose to start. After searching for a home on our mobile applications and websites, 
customers can choose to meet with a local real estate professional by connecting with a Premier Agent partner, scheduling 
an in-person home tour powered by ShowingTime+, or obtaining financing through Zillow Home Loans. For customers 
who are focused on buying new construction homes, we connect them with our home builder partners. Once buyers find 
their home, they can choose to work with our Premier Agent partners and affiliated integrated services, including 
financing through Zillow Home Loans, to facilitate a seamless transaction experience. For sellers, we are focused on 
providing multiple offerings for customers to find ways to sell their homes. For instance, we have an exclusive multi-year 
partnership with Opendoor to provide our customers with the option to get a cash offer on their home, and we have 
expanded this offering to 45 markets across the country. Additionally, we launched the Listing Showcase product under 
ShowingTime+, which allows sellers and listing agents to differentiate themselves on Zillow through higher-quality 
listings via an immersive premium experience featuring rich media, including scrolling hero images, room-by-room 
photo organization and interactive floor plans. For partners, we are actively integrating Follow Up Boss, a customer 
relationship management system for real estate professionals, into our suite of product offerings. This tech-enabled 
solution gives real estate professionals a central hub to organize and engage customers, close deals and build out their 
teams.  

For Renters – During 2023, we estimate that there were almost three times more households moving to a new rental than 
purchasing a home in the United States2. Our rentals marketplace assists our partners with listings, advertising, leasing 
and property management services through Zillow Rental Manager in the U.S. market of nearly 48 million rental units3. 
We connect prospective renters with our property management and landlord partners through our rental websites which

provide landlords access to the most visited online rental network4. We also provide renters with the ability to easily 
submit applications, sign leases and make rental payments through our platform. We are continuing to make 
enhancements to our rental products and services to make moving a transparent and seamless process. Such 
enhancements include the addition of room for rent listings, the ability to filter on income restricted listings, a universal 
application feature which allows potential renters to pay once to access multiple listings and the reporting of timely rental 
payments to a major credit bureau, among others. 

For Borrowers – Approximately 80% of all homes purchased in the U.S. are financed with a mortgage, 40% of all 
homebuyers start their home buying process shopping for a mortgage, and 80% of those buyers don’t yet have an agent5. 
In order to address this opportunity, we provide our customers with multiple ways to pursue mortgage financing for their 
transaction. We provide customers with the option to finance directly with Zillow Home Loans or to connect with our 
mortgage partners through our mortgage marketplace for both purchase and refinance opportunities. Zillow Home Loans, 
which is currently available in 49 states and the District of Columbia, originates mortgage loans and then sells 
substantially all of the loans on the secondary market.  

Competitive Advantages 

We believe we have the following competitive advantages: 

•  Large and trusted brand. The Zillow Group portfolio attracted an annual monthly high of 233 million unique users in 
June 2023 and approximately 10.0 billion visits in 2023, primarily to our Zillow, Trulia and StreetEasy portals. Today, 
more people search for “Zillow” than “real estate6,” and Zillow is the most visited7 and trusted8 brand in the online real 
estate industry. 

•  Living database of homes and superior data science and technology advantages. Our living database of approximately 
160 million U.S. homes is the result of substantial investment, sophisticated economic and statistical analysis and 
complex data aggregation of multiple sources of property, transaction and listing data, including user generated 
updates to more than 43 million property records. This data is the foundation of our proprietary Zestimate, Rent 
Zestimate, Zillow Home Value Index and Zillow Observed Rent Index models, as well as our housing and business 
forecasts. 

•  Superior industry partnerships. Zillow Group partners with thousands of the most productive names in real estate, 

maintaining strong partnerships with leading real estate agents, brokers, mortgage professionals, property managers, 
landlords, home builders, regional MLSs and more. Zillow is a licensed brokerage entity, which serves to enhance our 
partnership with MLSs. We aim to partner with high-performing and service-focused industry partners who share our 
interests in providing the best-possible services to our shared customers. Continually enhancing our partner network 
enables us to implement new products and features, introduce more customers to our best-performing partners and 
offer our shared customers an improved end-to-end transaction experience, including mortgages. 

•  Experienced, proven management team. We have a highly experienced management team who have successfully built 
Zillow and other brands into category leaders. We continue to add and develop executive talent with deep experience 
in building transaction-focused real estate, mortgage and e-commerce businesses. We believe the skills and 
experiences of our management team provide strategic insights and abilities to deliver a seamless real estate 
transaction experience for our customers.

•  Strong culture of innovation and inclusion. Zillow Group has built an award-winning culture of collaboration and 

innovation that is committed to employee equity and creating an environment where employees feel valued, supported 
and that they belong. We have been recognized for our commitment to these efforts, being named on JUST CapitalSM’s 
“America’s JUST 100 Companies” list. Additionally, in 2023, Zillow Group was named one of the Best Workplaces 
for Real Estate, for Parents and for Women9. Zillow Group was also named one of PEOPLE®’s 2023 “Companies 
That Care” list.  

•  Strong financial position. Our cash position and operating cash flow give us the flexibility to continue to invest in our 
growth pillars despite recent economic uncertainty and a volatile interest rate environment. We are mindful of our 
costs, while prioritizing our investments to drive our growth pillars and pursue the large opportunities we see ahead of 
us.  

Total Addressable Market 

We participate in large addressable markets of buying, selling, renting and financing residential real estate in the U.S. Our 

Total Addressable Market (“TAM”) includes Zillow’s estimate of total industry transaction fees derived from residential real 
estate transactions. In recent years, we have invested in software services, including the acquisition of Follow Up Boss and the 
expansion of offerings through our ShowingTime+ suite of services, to further enhance our ability to facilitate real estate 
transactions with both buyers and sellers. In addition, we provide important adjacent services, such as mortgages through 
Zillow Home Loans. Our TAM also includes our complementary rentals marketplace which includes rentals advertising and 
property management software spend.  

Our TAM has been affected in recent years by macroeconomic conditions that have proved unfavorable to the residential 
real estate industry. These macroeconomic conditions have driven low housing inventory, fewer new for-sale listings, increases 
and volatility in mortgage interest rates, as well as home price fluctuations. These factors have negatively impacted the number 
of real estate transactions and demand for adjacent services. Despite these macroeconomic headwinds, we believe we are well 
positioned to address existing and future demand for real estate transactions. The amounts listed below represent the estimated 
total industry size associated with these opportunities for the year ended December 31, 2023 (in billions):

Seasonality 

  $ 

148  
657

12  

Portions of our business have historically been affected by seasonal fluctuations in the residential real estate market, 

advertising spend and other factors.  We generally expect Residential and Rentals revenue to peak in the three months ended 
June 30th or September 30th, consistent with the average number of visits and unique users which have historically peaked 
during the same period. Within Mortgages revenue, we believe that seasonality would result in higher purchase origination 
volumes in the spring and summer high seasons, and our Connect and Custom Quote mortgage marketing products have 
displayed similar seasonal fluctuations. In more recent years, our seasonality in revenue has been masked by macroeconomic 
factors. These factors include customers’ responses to macroeconomic housing market factors, such as interest rate and home 
price increases and volatility and tight housing inventory levels, and the impact of the COVID-19 pandemic. 

Competition 

Our business depends on our ability to successfully attract, retain and provide customers with products and services that 

make real estate transactions faster, easier and less stressful.  

The residential real estate landscape is highly fragmented and competitive from the beginning of the search process 
through the closing of a transaction, typically with single point service providers. Approximately 4.8 million existing and new 
homes were sold in the U.S. in 202319, with over 201,000 real estate brokerages20 and over 70,000 mortgage lenders21 providing 
their services across more than 500 different MLSs that span the country22. Zillow Home Loans currently makes up less than 
0.09% of the mortgages originated in the U.S.  

We compete for customers with companies that provide technology, products and services for real estate focused 
customers. Factors that may influence customer decisions include the quality of the experience, value and utility of the services 
offered, the breadth, depth and accuracy of information available, and brand awareness and reputation. For example, our 
Premier Agent business competes for customers based on price, visibility, perceived and actual value and quality of service. For 
customers shopping for a mortgage, Zillow Home Loans competes with other mortgage originators based on a combination of 
interest rates, origination fees, product selection, brand awareness and trust and the level of service we provide. 

In addition, our business depends on our ability to attract and retain leading industry partners to advertise and provide 
services to our customer base. We compete for real estate partners based on the perceived transaction readiness of customers, 
return on investment, price and product offerings and the effectiveness and relevance of our products and services. Based on 
these and other factors, real estate partners could select other companies to work with to provide relevant and timely real estate,

rental, new construction and mortgage information and services. We also compete for a share of our partners’ overall marketing 
budgets with traditional media as well as word-of-mouth referrals and leads from yard signs and other marketing.  

Intellectual Property 

We regard our intellectual property as a key differentiator that is critical to our success and we rely on a combination of 
intellectual property laws, trade-secret protection, and contractual agreements to protect our proprietary technology and data.   

Our Zestimate feature, which we consider to be a significant competitive advantage with respect to customer engagement, 

leverages patented, proprietary, automated valuation models to provide real-time home value estimates. As of December 31, 
2023, we have 138 patents of varying lengths issued and 203 patent applications pending in the U.S. and internationally. These 
patents cover a variety of proprietary techniques relevant to our products and services, including determining a current value for 
real estate property and the collection, storage and display of home attribute values and creating interactive floor plans.  

In addition, awareness and loyalty to our brand enables us to effectively attract and retain our customers and employees. 

To support our brand, we have registered, or applied for the registration of, trademarks, service marks and copyrights in the 
U.S. and several other jurisdictions, including “Zillow,” “Zestimate,” and the Z in a house logo. We are also the registered 
holder of a variety of domestic and international domain names. We have licensed in the past, and we may license in the future, 
certain of our proprietary rights to third parties. 

To further protect our proprietary rights, we enter into confidentiality and proprietary rights agreements with our 
employees, consultants, contractors and business partners. Our employees and contractors are also subject to invention 
assignment provisions. We control the use of our proprietary technology, data and intellectual property through provisions in 
both our general and product-specific terms of use and other restrictions on our mobile applications and websites. 

Government Regulation 

We operate in an increasingly complex legal and regulatory environment. Our business and the products and services that 

we offer are affected by a continually expanding and evolving range of local, state, federal, and international laws and 
regulations. For additional information on government regulation refer to Part I, Item 1A (Risk Factors—Risks Related to 
Regulatory Compliance and Legal Matters) of this Annual Report on Form 10-K. 

Human Capital Resources 

At Zillow, we believe that our long-term success is dependent upon attracting, developing and retaining talented 

employees, and maintaining a culture that allows each employee to do their best work. We value integrity, accountability, 
collaboration, creativity, respect and transparency as central to our core values. 

As of December 31, 2023, we had 6,263 employees. Our internal data shows that approximately 55% of our workforce 

self-identified as men and approximately 45% self-identified as women, as well as certain employees that identified as 
nonbinary. Women currently represent 43% of our leadership team (defined as director level and above). The ethnicity of our 
workforce was 58% White, 20% Asian, 9% LatinX, 8% Black and 5% for all other races. For leadership, the breakdown was 
72% White, 17% Asian, 5% Black, 4% LatinX and 2% for all other races. The diversity of our workforce and leadership team 
continues to be an area of focus as further described in the “Equity and Belonging” section below.   

Zillow as a Flexible Workforce 

We have redefined the employee experience and the future of flexible work, beginning with our announcement of a 

permanent move to a flexible workforce in late 2020. With this permanent move and our investments in recruiting, retaining, 
developing, and listening to and learning from our diverse talent, Zillow is setting the standard for great employee experiences 
and a positive work culture. We believe these investments increase our applicant pool and lead to lower employee attrition. We 
offer employees the choice to work from wherever they are most productive. We continue to evolve our flexible work model to 
more effectively use our time together, provide more opportunities to work asynchronously, and allow all employees to thrive 
regardless of location. Our base pay compensation frameworks seek to prioritize performance over geographic location when 
making pay decisions. This compensation philosophy allows us to compete for talent nationally. As we have transitioned to a 

8 

 
 
 
flexible workforce, we are also using this opportunity to diversify our workforce, as we are no longer bound by the geographic 
limits of our physical workspaces.   

Our offices will continue to be a place for teams to come together to enable productivity and collaboration, though on a 

far less frequent basis. Since our permanent move to a flexible workforce, we have redesigned our physical workspaces to 
provide more space for collaboration and engagement, especially to support team gatherings, which we call zRetreats. In 2023, 
we focused on balancing flexible work with impactful in-person connections, where cross-functional teams and organizations 
came together periodically to build connections, trust and collaborate in person. In 2024, our focus will be continuing to refine 
our office footprint to align to how our local and traveling employee populations use our office spaces, as we continue to test 
zRetreat and collaboration spaces that best support our employees. 

Equity and Belonging 

In pursuit of our business goals, we prioritize and embed inclusive, equitable practices and systems in our values and how 

we work. We are committed to creating a workplace where diversity of gender, gender identity, age, race, ethnicity, sexual 
orientation, national origin, disability, military status and religion are represented, embraced and respected. Our dedicated 
Equity and Belonging team empowers Zillow Group employees to build a strong community, amplify underrepresented voices, 
and foster a company culture where everyone can learn, grow and thrive. We maintain equity and belonging programs that 
include unconscious bias training, nine employee-led employee resource groups for community members and allies, and 
support diversity in our recruitment practices. In 2023, we launched a new Equity and Belonging Executive Advisory Council 
comprising senior leadership charged with setting the tone and vision for our commitments, including establishing goals and 
responsibilities and evaluating impact. 

Pay Equity 

Zillow Group is committed to ensuring all employees in similar roles with similar qualifications are paid equitably 

regardless of their identity. In support of this commitment, we complete a comprehensive bi-annual evaluation with the 
commitment to disclose results publicly on our corporate website annually. Based on our assessment of compensation in 2023, 
we have found that employees with similar skills are paid within approximately 1% of each other when we control for certain 
job-related pay factors, including but not limited to job title and function. At Zillow Group, in 2023, White men, Asian women 
and LatinX women had controlled pay of $1.00 and Black women and women of two or more races had controlled pay at $0.98. 
White women, LatinX men, Black men, and men of two or more races at Zillow Group had pay equity of $0.99 and Asian men 
had a pay equity of $1.01. We will continue our commitment and comprehensive reviews of pay equity and will look to expand 
our data collection and analysis to include LGBTQ+ data in the future. 

Career and Leadership Development  

At Zillow Group, we believe each of our employees should have the tools and support they need to grow their careers 

through experiences, resources and connections. We have a dedicated Talent Success team, which creates educational resources 
and conducts training on a wide range of topics including job-specific onboarding, effective communication, collaboration, as 
well as sophisticated leadership training programs and experiences with focused learning tracks for both new managers and 
experienced leaders. In 2023, we offered over 900 online learning opportunities through Zillow University, our internal online 
training platform. Zillow Group employees have completed nearly 70,000 hours of content in 2023 on the Zillow University 
and LinkedIn Learning® platforms. 

A key piece in development is cultivating a learning culture where learning is a habit, and learning agility is at the 
forefront. This means creating the right learning resources for our employees for their current and future roles. We have 
developed a robust Learning and Development portfolio that includes a number of key career development programs that 
support our employees to equip them with the knowledge and experience to grow their careers. Below is a summary of certain 
of these programs: 

•  Leadership Entrance Experience Program (LEEP) is a self-paced curriculum designed for individual contributors who 

want to explore people management and develop their leadership skills.  

9 

 
 
 
•  Professional skills development through courses like Public Speaking, Insights Discovery® workshops, and access to 

virtual coaching.  

•  Access to development platforms that connect employees to mentors, professional coaches, and peers to aid in 

reaching career goals 

Our people managers play a critical role in moving our business forward by coaching their team, developing their talent 

and providing strong communication to create team engagement. To help achieve this goal, we utilize our Leadership 
Expectations, a leadership development guide that outlines our Leadership Philosophy, provides the foundation of our 
leadership development programs and sets forth our expectations for leaders and the behaviors that are essential to create a 
consistent leadership experience at Zillow Group. In 2023, we further enhanced the Leadership Expectations by defining 14 
specific manager capabilities that bring clarity to managers on how to lead and manage teams in our flexible work environment. 
With this, we began the launch of our virtual manager capability summits, designed for our director and below leaders to help 
develop the manager capabilities. In 2024, we plan to launch bi-annual summits, for a total of 12 hours of training for each 
director and below people manager, while offering customized learning paths on async content between training sessions, along 
with peer-to-peer mentoring.  

Talent Rewards 

Talent Rewards includes the strategic oversight of compensation, benefits, and immigration/mobility programs whose 
purpose is to reinforce talent attraction, retention and development in support of Zillow’s culture. Throughout 2023, we have 
continued to refine our rewards program. We have increased transparency and consistency in our candidate offers through a 
redesign of our total compensation package. We conduct ongoing reviews of employee compensation to ensure that our 
employees are paid fairly and in alignment with market expectations. 

In addition, our robust benefits are reflected in investments in physical, family, mental and financial wellness programs to 
meet the needs of our diverse base of employees. These benefits include workplace-location flexibility, competitive health care 
coverage, fully paid parental leave, a sabbatical program, wellness reimbursements, tuition support and caregiver resources. We 
have also updated our benefits program through enhanced offerings around mental health, LGBTQ+ provider navigation 
support, as well as fertility and family planning. Beginning in 2023, we enhanced our parental leave policy, which now allows 
for up to 20 weeks of paid parental leave. These ongoing investments continue to reinforce Zillow’s commitment to an 
equitable, healthy, focused and high-performing workforce.

Our business is subject to numerous risks. You should carefully consider the following risk factors, as any of these risks 
could harm our business, results of operations, and future financial performance. Recovery pursuant to our insurance policies 
may not be available due to policy definitions of covered losses or other factors, and available insurance may be insufficient to 
compensate for damages, expenses, fines, penalties, and other losses we may incur as a result of these and other risks. In 

12 

 
 
addition, risks and uncertainties not currently known to us or that we currently deem to be immaterial may materially and 
adversely affect our business, financial condition and operating results. If any of these risks occur, the trading price of our 
common and capital stock could decline, and you could lose all or part of your investment. 

Risks Related to Our Business and Industry 

Our Business and Operating Results Have and May Continue to Be Impacted by the Health of the United States Residential 
Real Estate Industry and May Be Negatively Affected by Downturns or Significant Changes in This Industry and General 
Economic Conditions. 

The success of our business depends, directly and indirectly, on the health of the United States residential real estate 
market. The health of the United States residential real estate market is affected, in part, by general economic conditions beyond 
our control. Recent market factors, including low housing inventory, fewer new for-sale listings, volatility in mortgage interest 
rates and home price fluctuations, inflationary conditions and rental occupancy rate fluctuations have impacted demand for our 
products and services by consumers and advertisers, which in turn has negatively impacted our financial performance. The 
extent to which these and additional economic factors, such as those described below, impact our results and financial position 
will depend on future developments, which are uncertain and difficult to predict: 

• 

• 
• 
• 
• 
• 
• 
• 

• 
• 
• 

• 
• 

• 
• 

fluctuations in the United States residential real estate market – both seasonal and cyclical – which may be due to one 
or more factors, whether included in this list or not; 
changes in federal monetary policy or inflationary conditions; 
changes in international, national, regional, or local economic, demographic, or real estate market conditions; 
slow economic growth or recessionary conditions; 
increased levels of unemployment or a decrease in labor availability, and/or slowly growing or declining wages; 
declines in the value of residential real estate and/or the pace of home appreciation, or the lack thereof; 
illiquidity in residential real estate; 
overall conditions in the housing market, including macroeconomic shifts in demand, and increases in costs for 
homeowners such as property taxes, homeowners association fees and availability and affordability of insurance; 
low levels of customer confidence in the economy and/or the United States residential real estate industry; 
low home and/or rental inventory levels or lack of affordably priced homes and rentals; 
changes in interest rates, mortgage rates or down payment requirements and/or restrictions on mortgage financing 
availability; 
changes to how real estate commissions are negotiated or paid, or changes to other industry standards and practices;  
federal, state, or local legislative or regulatory changes that would negatively impact rental properties or the residential 
real estate industry, such as the Tax Cuts and Jobs Act of 2017 (the “Tax Act”), which limited deductions of certain 
mortgage interest expenses and property taxes; 
volatility and general declines in the stock market; and/or 
natural and man-made disasters and other catastrophic events, such as pandemics, hurricanes, earthquakes, wildfires, 
terrorist attacks and other events that disrupt local, regional, or national real estate markets. 

Residential real estate may be impacted by industry changes, including as the result of certain or future class action lawsuits 
or government investigations. (cid:3)

The residential real estate industry faces significant pressure from private lawsuits and investigations by the Department 
of Justice (the “DOJ”) with regards to antitrust issues, including with respect to lawsuits and investigations in which we are not 
a named party. (cid:3)

In April 2019, the National Association of Realtors (“NAR”) and certain brokerages and franchisors (including Realogy 

Holdings Corp., HomeServices of America, Inc. RE/MAX and Keller Williams Realty, Inc.) were named as defendants in a 
class action complaint alleging a conspiracy to violate federal antitrust laws by, among other things, requiring residential 
property sellers in Missouri to pay inflated commission fees to buyer brokers (the “NAR Class Action”). On October 31, 2023, 
a jury found NAR and various of its co-defendants liable and awarded plaintiffs nearly $1.8 billion in damages (an award that is 
subject to trebling), and additional equitable relief that may require changes to existing business models may be forthcoming. 

13 

 
 
Class action suits raising similar claims are already pending in other jurisdictions and the outcome of the NAR Class Action and 
other pending litigation may result in additional actions being filed.  (cid:3)

While the final outcomes of any pending or future lawsuits cannot be predicted with any certainty, court decisions, 
privately negotiated settlements, and concerns about the future outcomes of such lawsuits could result in outcomes that impact 
the industry as a whole. For example, such lawsuits could lead to changes in how real estate commissions are negotiated, 
calculated, or paid, which may in turn meaningfully impact how home buyers and sellers engage with real estate professionals 
in the course of buying and selling a home. (cid:3)

Beyond the NAR Class Action and various similar private actions already pending, beginning in 2018, the DOJ 
commenced an investigation into NAR for violations of the federal antitrust laws. The DOJ and NAR appeared to reach a 
resolution in November 2020, resulting in the filing of a Complaint and Proposed Consent Judgment pursuant to which NAR 
agreed to adopt certain rule changes, such as increased disclosure of commission offers. The DOJ has since sought to continue 
its investigation of NAR, and the question of whether the earlier settlement forecloses further investigation is currently being 
litigated. It is uncertain what effect, if any, the resumption of the DOJ’s investigation could have on the larger real estate 
industry, including any further settlement that may result therefrom. Beyond monetary damages, the various class action suits 
seek to change real estate industry practices and, along with the DOJ investigation, have prompted state and local real estate 
boards or multiple listing services to discuss and consider changes to long-established rules and regulations. (cid:3)

Although changes arising from these lawsuits and investigations are uncertain and challenging to predict, they could 
result in outcomes that materially impact our business, financial condition, and results of operations. For example, if agent 
commissions are meaningfully impacted, it could reduce the marketing budgets of real estate partners or reduce the number of 
real estate partners participating in the industry, which could adversely affect our financial condition and results of operations. (cid:3)

If Real Estate, Rental and Mortgage Professionals, Home Builders, Property Managers or Other Real Estate Partners 
Reduce or End Their Spending With Us or if We Are Unable to Effectively Manage Advertising and Product Inventory or 
Pricing, Our Business Could Be Harmed.  

Our business depends in part on revenue generated through sales of advertising and other products and services to real 
estate agents and brokerages, rental professionals, mortgage professionals, home builders, property managers, and other real 
estate partners in categories relevant to real estate (collectively, “real estate partners”). Our ability to attract and retain real 
estate partners, and ultimately to generate advertising revenue, depends on a number of factors, including how successfully we 
can: 

• 

• 
• 
• 

• 

increase the number of customers who use one or more of our products and services to effectuate transactions and the 
frequency of their use, provide them with tools to promote engagement between real estate market participants, and 
enhance their user experience so we can retain them; 
offer an attractive return on investment to our real estate partners for their spending with us; 
continue to develop our products and services to increase adoption by and engagement with our real estate partners; 
keep pace with and anticipate changes in technology to provide industry-leading products and services to real estate 
partners and customers; and 
compete effectively for advertising dollars with other options. 

Residential revenue accounted for 75% of total revenue for the year ended December 31, 2023. This level of revenue 

concentration suggests that even modest decreases in individual spending across the real estate partner population, caused by 
actual or perceived decreases to return on investment, preference for a competitive product or service, or other factors, could 
have a significant negative impact on our ability to use proceeds generated from our Residential products and services to invest 
in our other products and services, which we view as a key competitive advantage. Any such decreases in spending could also 
adversely affect our results of operations. We do not have long-term contracts with many of our real estate partners. Our real 
estate partners could choose to modify or discontinue their relationships with us with little or no advance notice. For example, 
our auction-based account interface for Premier Agent partners allows agent partners to independently control the duration of 
their advertising commitments for varying terms.  

14 

 
 
We may not succeed in retaining existing real estate partners’ spending or capturing a greater share of such spending if 

we are unable to convince real estate partners of the effectiveness or superiority of our products as compared to alternatives. In 
addition, we continually evaluate and utilize various pricing and value delivery strategies in order to better align our revenue 
opportunities with the growth in usage of our mobile and web platforms and customer transactions. For example, we offer a pay 
for performance pricing model called “Flex” for Premier Agents in certain markets. With the Flex model, Premier Agents 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. With this pricing model, the transaction price represents variable consideration, as the amount to 
which we expect to be entitled varies based on the number of validated leads that convert into real estate transactions and the 
value of those transactions. To estimate variable consideration and revenue associated with the Flex model, we use a number of 
assumptions, including estimating the conversion rate of a lead to a real estate transaction, estimating the velocity of 
conversions and estimating the fee amounts likely to be received. We use similar performance based models for our rentals pay 
per lease and StreetEasy Experts products. 

Our estimates of variable consideration are primarily developed based on historical data and our future expectations 

based on current market trends. Our estimation methodology may be inaccurate and some or all of the revenue we recognize 
when our performance obligations are satisfied may be reversed. Realization of performance-based revenue is also dependent 
on accurate reporting and remittance by our partners.  

Future changes to our pricing or lead delivery methodologies for advertising services or product offerings may cause real 
estate partners to reduce or end their spending with us or negatively impact our ability to manage revenue opportunities. If real 
estate partners reduce or end their spending with us, or if we are unable to effectively manage inventory and pricing, our 
advertising revenue and business, results of operations and financial condition could be harmed. In addition, we use revenue 
generated from our real estate partners, in part, to fund our operations and investments in our growth pillars. Significant 
decreases in revenue generated from our real estate partners may negatively impact our ability to fund operations and invest in 
our growth.  

We May Not Be Able to Maintain or Establish Relationships With Real Estate Brokerages, Real Estate Listing Aggregators, 
Multiple Listing Services, Property Management Companies, Home Builders and Other Third-Party Listing Providers, 
Which Could Limit the Information We Have to Power Our Products and Services. 

Our ability to attract customers to our mobile applications, websites and other tools depends to some degree on providing 
timely access to comprehensive and accurate real estate listings and information. To provide these listings and this information, 
we maintain relationships with real estate brokerages, real estate listing aggregators, multiple listing services (“MLSs”), 
property management companies, home builders, other third-party listing providers and homeowners and their real estate agents 
to include listing data in our services (collectively, “real estate listing providers”). Many of our agreements with real estate 
listing providers may be terminated with limited notice or cause. Many of our competitors and other real estate websites have 
similar access to MLSs and listing data and may be able to source certain real estate information faster or more efficiently than 
we can. Another industry participant or group could create a new listings data service, which could impact the relative quality 
or quantity of information of our listing providers. The loss of existing relationships with real estate listing providers, whether 
due to termination of agreements, loss of MLS memberships, or otherwise, changes to our rights to use or timely access listing 
data or an inability to continue to add new listing providers or changes to the way real estate information is shared, may 
negatively impact our listing data quality. This could markedly decrease the quantity and quality of the for sale and rental listing 
data and other real estate information that we provide, reduce customer confidence in our products and services and cause 
customers to go elsewhere for real estate listings and information, which could severely harm our business, results of operations 
and financial condition. 

We May Not Be Able to Maintain or Establish Relationships With Other Data Providers, Which Could Limit the Information 
We Are Able to Provide to Our Customers and Impair Our Ability to Attract or Retain Customers. 

In addition to the information that we receive from real estate listing providers, we obtain certain real estate data, such as 
transaction history, property descriptions, tax-assessed value and property taxes paid, under licenses from other third-party data 
providers, including state and local governments. We use this data to enable the development, maintenance and improvement of 
our marketplace and information services, including Zestimates, Rent Zestimates and our living database of homes. We have 

15 

 
 
invested significant time and resources to develop proprietary algorithms, valuation models, software and practices to use and 
improve on this specific data. We may be unable to access certain of this data from vendors or government agencies if changes 
in local laws or regulations or other prohibitions on data sharing are implemented or because the quality and quantity of data 
available to these third parties changes, or because we violate (or are perceived to have violated) the agreements under which 
we obtain such data. We may also be unable to renew our licenses with these data providers or enter into new data license 
agreements, or we may be able to do so only on terms that are less favorable to us, which could harm our ability to continue to 
develop, maintain and improve these information services and could harm our business, results of operations and financial 
condition. 

If We Fail to Comply With the Rules and Compliance Requirements of MLSs, Our Access to and Use of Listings Data May 
Be Restricted or Terminated. 

Our subsidiaries that access and use listings data through MLS memberships (the “MLS Members”) must comply with 
each MLS’s rules, compliance requirements and data license agreements to maintain their access to listings data and remain a 
member in good standing. Each MLS that the MLS Members belong to has adopted its own rules, policies, and agreement 
terms governing, among other things, how MLS data may be used and how listings data must be displayed on our websites and 
mobile applications. The MLS Members are also subject to compliance operations requirements and, as a result, must respond 
to and resolve complaints or notices of non-compliance from the MLS or other MLS participants on required timelines. The 
MLS rules and compliance requirements may not contemplate multi-jurisdictional licensed brokerage entities. MLS rules vary 
among markets and are in some cases inconsistent between MLSs, such that we are required to customize our websites, mobile 
applications, or services to accommodate differences between MLS rules and compliance requirements. Handling complaints 
received by the MLS Members across markets may create heightened operational or financial risks with short response and 
resolution deadlines. Complying with the rules and compliance requirements of each MLS requires significant investment, 
including personnel, technology and development resources, and the exercise of considerable judgment. Rules and compliance 
requirements of MLSs may be changed across markets, including potential for targeted changes or interpretations in response to 
our operations. If any of the MLS Members are deemed to be noncompliant with an MLS’s rules or to have provided improper 
responses to or resolution of complaints, they may face disciplinary sanctions by that MLS, which could include monetary 
fines, restricting, suspending or terminating our access to that MLS’s data, or other disciplinary measures. The loss or 
degradation of this listings data could materially and adversely affect traffic to our mobile applications and websites, which 
could severely harm our business, results of operations and financial condition. 

If Our Data Integrity Suffers Real or Perceived Harm, Customers and Real Estate Partners May Decrease Use or 

Cease Using Our Products and Services, and We May Be Subject to Legal Liability. 

Because homes represent significant investments, and many customer decisions regarding homes are data-driven, our 

ability to attract and retain customers and real estate partners to our products and services is dependent upon our ability to 
publish, and reputation for publishing, accurate and complete residential real estate information, including the output of 
proprietary models, through our mobile applications and websites. As discussed above, a significant amount of the data we 
publish on our mobile applications and websites is derived from third parties, and we have limited ability to control the quality 
of the information we receive from them. We also publish a significant amount of customer-generated content, and our tools 
and processes designed to ensure the accuracy, quality and legality of such content may not always be effective. Data we 
generate independently are subject to error, unauthorized modification by way of third-party viruses and other factors. As the 
volume of data we publish increases, and potential threats to data quality become more complex, the risk of harm to our data 
integrity also increases. If our data integrity suffers real or perceived harm, we may be subject to legal liability, reputational 
damage and customers and real estate partners may decrease their use or cease using our products and services, which would 
harm our results of operations and financial condition. 

If We Do Not Innovate or Provide High-Quality Products and Services That Deliver Efficient and Integrated Transaction 
Experiences to Our Customers and Real Estate Partners, Our Business Could Be Harmed. 

Our success depends on our continued innovation to provide new, and improve upon existing, products and services that 

make real estate transactions faster, easier and less stressful for our customers and provide value to real estate, rental and 
mortgage professionals, home buyers and sellers and our other real estate partners. As a result, we must continually invest 

16 

 
 
significant resources in research and development to improve the attractiveness, competitiveness, and comprehensiveness of 
our products and services, enable smoother and more efficient real estate transactions, adapt to changes in technology and 
support new devices and operating systems. If we are unable to provide products and services that our customers want to use, 
on the devices they prefer, then those customers may become dissatisfied and use competitors’ mobile applications, websites, 
products and services. If our customers begin to access more real estate information and services through other media and we 
fail to innovate, our business may be negatively impacted. If we are unable to continue offering high-quality, innovative 
products and services, we may be unable to attract additional customers and real estate partners or retain our current customers 
and real estate partners, which could harm our business, results of operations and financial condition. 

We Face Competition for Users in the Real Estate Category, Which Could Impair Our Ability to Attract Users of Our Mobile 
Applications, Websites and Other Products and Services, Which Could Harm Our Business, Results of Operations and 
Financial Condition. 

Our business model depends on our ability to continue to attract users to our mobile applications, websites, real estate 
services and other services and enhance their engagement with our products and services in a cost-effective manner. In addition, 
our ability to be successful depends, in part, on attracting users who have historically shopped for or bought, sold, rented, or 
financed their homes through more traditional channels. New entrants continue to join the real estate space at a rapid pace and 
the tools and services for buying, selling, renting, or financing homes are significantly less developed than in other industries, 
such as books, music, travel and other consumer products. Our existing and potential competitors include companies that 
operate, or could develop, national and local real estate, rental, new construction, mortgage, and title and escrow businesses. 
Such competitors range from companies offering traditional offline advertising media, like newspapers, to innovative 
technology companies and from real estate investors, like institutional investors and iBuyers, to mortgage lenders and title and 
settlement service providers. These companies could devote greater financial, technical and other resources than we have 
available to real estate services, sales, advertising or research and development, have a more accelerated time frame for 
deployment or leverage their existing customer bases and proprietary technologies to provide products and services that users 
might view as superior to our offerings. Any of our future or existing competitors may introduce different services or solutions 
that attract users or provide services or solutions similar to our own but with better branding or marketing resources. Any of our 
current or future competitors could merge with each other or a separate entity, which may enable them to compete with us even 
more vigorously and acquire a greater share of customer transactions and engagement. In addition, search engines are always 
evolving and changes to their models or algorithms may negatively impact our placement or require greater investment of 
resources to optimize our placement and attract customers. If the use of online products and services for shopping, renting, 
buying, selling, or financing residential real estate does not continue to develop and grow or we are not able to continue to 
attract users to our mobile applications, websites, real estate services and other services, our business, results of operations and 
financial condition could be harmed. 

We May Not Be Able to Compete Successfully Against Our Existing or Future Competitors in Attracting Customers for Our 
Products and Services or Real Estate Partners, Which Could Harm Our Business, Results of Operations and Financial 
Condition. 

We face intense competition in each of our lines of business. We compete with a variety of real estate transaction service 

providers to attract customers engaging in real estate transactions and we also compete with traditional and online or mobile 
media sources to attract real estate partners. Please see “Competition” under Part 1, Item 1 of this Annual Report on Form 10-K 
for a general discussion of the competitive conditions in each of our businesses. 

Competitors for our real estate transaction services include rental listing service providers, real estate brokers, real estate 
investors, mortgage lenders, mortgage brokers, financial institutions, and title and settlement service providers. Many of these 
competitors may have considerable competitive advantages, including longer operating histories, more extensive financial 
resources, stronger brand equity, more industry experience and greater knowledge and expertise. As a result, these competitors 
may have an advantage in attracting customers, recruiting highly skilled personnel, and growing or maintaining their 
businesses. They may also provide customers with real estate transaction services and experiences superior to or more cost-
effective than ours. 

17 

 
 
We compete against mobile applications and websites dedicated to providing real estate, rental, new construction and 

mortgage information and services to real estate professionals and customers, major internet portals, general search engines, e-
commerce and social media sites as well as other technology and media companies. We also compete for a share of our real 
estate partners’ overall marketing budgets with traditional media such as television, magazines, newspapers and 
home/apartment guide publications, particularly with respect to advertising dollars spent at the local level by real estate 
professionals to advertise their qualifications and listings. Large companies with significant brand recognition have large 
numbers of direct sales personnel and substantial proprietary advertising inventory and mobile application and website traffic, 
which may provide a competitive advantage. To compete successfully for real estate transaction partners against future and 
existing competitors, we must continue to invest resources in developing our advertising platform and proving the effectiveness 
and relevance of our advertising products and services. Pressure from competitors seeking to acquire a greater share of our real 
estate partners’ overall marketing budget could adversely affect our pricing and margins, lower our revenue and increase our 
research and development and marketing expenses. 

If we are unable to compete successfully against our existing or future competitors, we could lose or fail to gain customer 

transaction share and our business, results of operations or financial condition would be harmed. 

We Compete in a Dynamic Industry, and We May Invest Significant Resources to Pursue Strategies, Develop New Products 
and Services and Expand Existing Products Into New Markets That Do Not Prove Effective. 

The industry for residential real estate transaction services, technology, information marketplaces and advertising is 
dynamic, and the expectations and behaviors of customers and professionals shift constantly and rapidly. We continue to learn a 
great deal about the behaviors and objectives of residential real estate market participants as the industry evolves and invest 
significant resources to develop, test and launch products and services to address the needs of the market and improve the home 
buying, selling, financing, building and renting experience. Changes or additions to our products and services, including 
expansion of existing products and services into new markets, may not attract or engage our customers, may reduce confidence 
in our products and services, may negatively impact the quality of our brands, may upset our partners or other industry 
participants, may expose us to increased market or legal and regulatory risks, may subject us to new laws and regulations, and 
may result in reduced investor confidence or otherwise harm our business. For example, if MLSs or other real estate market 
participants engage in exclusionary conduct that limits our ability to effectively compete, it may negatively impact our business. 
On December 22, 2023, Zillow Group, Inc., and ShowingTime.com, LLC filed suit in the United States District Court of 
Arizona against Arizona Regional Multiple Listing Service, Inc., Multiple Listing Service, Inc., and MLS Aligned, LLC under 
federal antitrust laws to prevent the defendants from unlawfully attempting to monopolize the market for real estate showing 
management services in the geographic regions they control and from unlawfully conspiring to exclude or severely limit 
ShowingTime in those markets.  

Further, if we do not realize the benefits we expect from the strategic relationships or we enter into or acquisitions we 

complete, our business could be harmed. Customers may prefer other service providers because they offer different or superior 
services or those services are easier to use, faster or more cost effective than our services. We may not successfully anticipate or 
keep pace with industry changes, and we may invest considerable financial, personnel and other resources to pursue strategies 
that do not ultimately prove effective such that our results of operations and financial condition may be harmed.  

Natural Disasters, Geopolitical Events and Catastrophic Events May Disrupt Real Estate Markets, or Otherwise Harm Our 
Business. 

The occurrence of a significant natural disaster or other catastrophic event such as a pandemic, health crisis, earthquake, 

hurricane, windstorm, fire, flood, power loss, telecommunications failure, cyber-attack, geopolitical instability, war, civil unrest, 
terrorist attack or other similar event, may disrupt our operations, impair local and regional real estate markets or economies 
and negatively impact our business, results of operations and financial condition. For example, the COVID-19 pandemic, 
including the reactions of governments, markets, and the general public to the COVID-19 pandemic, caused adverse 
consequences for our business and results of operations. 

Zillow provides products and services to customers throughout the United States and to a lesser extent, in Canada. In 

addition, Zillow Home Loans originates loans in 49 states and the District of Columbia. The occurrence of a natural disaster or 

18 

 
 
other catastrophic event in any of these localities could have a significant negative impact on those real estate markets and the 
success of our business in the affected regions. 

Although the majority of our workforce has shifted to a distributed work environment, we maintain large employee 

populations, including those supporting our licensed operations, in Seattle, Washington; New York, New York; Atlanta, 
Georgia; San Francisco, California; Irvine, California; Denver, Colorado; Mexico City, Mexico and Belgrade, Serbia. An 
earthquake or other natural disaster or catastrophic event in any of these cities could disrupt our engineering, sales, operations 
and/or mortgage origination teams and equipment critical to the operation of our business. Similarly, a significant natural 
disaster or other catastrophic event in any major United States city could negatively impact a large number of our real estate 
partners and customers and cause a decrease in our revenue or traffic.  

Business continuity and disaster recovery planning is important, and if we are unable to develop adequate plans to ensure 

that our business functions continue to operate during and after a disaster or catastrophic event, and successfully execute on 
those plans in the event of a disaster, catastrophic event, or other emergency, our business and reputation may be harmed. 

Our Dedication to Making Decisions Based Primarily on the Best Interests of Customers May Cause Us to Forgo Short-
Term Gains. 

Our guiding principle is to build our business by making decisions based primarily on the best interests of our customers, 

which we believe has been essential to our success in increasing our customer growth rate and engagement and has served the 
long-term interests of our company and our shareholders. In the past, we have forgone, and we will in the future forgo, certain 
expansion or short-term revenue opportunities that we do not believe are in the best interests of customers, even if such 
decisions negatively impact our short-term results of operations. In addition, our philosophy of putting customers first may 
negatively impact our relationships with our existing or prospective real estate partners. This could result in a loss of real estate 
partners, which could harm our revenue and results of operations. For example, in November 2021, we announced plans to 
wind down Zillow Offers operations, in part, because it served too narrow a portion of our customers, instead opting to develop 
and offer other products and services primarily focused within our six growth pillars. In addition, we require our Premier Agent 
partners to maintain a minimum customer experience score and if they fail to do so after a probation period, we have canceled 
advertising from those partners on our platforms. Our customer focus may also negatively impact our relationships with real 
estate brokerages, MLSs, and other industry participants on whom we rely for listings information. Zillow Home Loans and 
some of our business-to-business products, for example, may be perceived as impinging upon the business models of real estate 
agents, brokerages and lenders, which may cause them to terminate or decrease the scope of their relationships with us. Such 
risks could have a materially negative impact on our results of operations. Our principle of making decisions based primarily on 
the best interests of customers may not result in the long-term benefits that we expect, in which case our user traffic and 
engagement, business and results of operations could be harmed. 

We Are Subject to Disputes and Current or Proposed Rules and Regulations Regarding the Accuracy or Display of Our 
Zestimates and Rent Zestimates. 

We provide our customers with Zestimate and Rent Zestimate home and rental valuations. Zestimates are our estimated 

current market values of a home based on our proprietary automated valuation models that apply advanced algorithms to 
analyze our data; they are not appraisals. A Rent Zestimate is our estimated current monthly rental price of a home, using 
similar automated valuation models that we have designed to address the unique attributes of rental homes. We are, from time 
to time, involved in disputes with property owners and others who disagree with the accuracy or display of a Zestimate or Rent 
Zestimate, and such disputes may result in costly litigation in the future. Further, revisions to our automated valuation models, 
or the algorithms that underlie them, poor data quality, or other factors may cause certain Zestimates or Rent Zestimates to vary 
from expectations for those Zestimates or Rent Zestimates. Any such dispute or variation in Zestimates or Rent Zestimates 
could result in distraction from our business or potentially harm our reputation and financial condition. Among other things, we 
are also subject to proposed legislation that may impose liability or disclosure of our proprietary algorithms, which could 
impact our competitive advantage and potentially harm our financial position or business results. This legislation could also 
result in an increased occurrence of enforcement actions or legal disputes as discussed above. 

19 

 
 
We Rely on the Performance of Highly Skilled Personnel, and if We Are Unable to Attract, Retain and Motivate Well-
Qualified Employees, Our Business Could Be Harmed. 

We believe our success has depended, and continues to depend, on the efforts and talents of our management and our 

highly skilled team of employees, including our software engineers, data scientists, shared services staff, loan officers, 
statisticians, marketing professionals and advertising sales staff. Our future success depends on our continuing ability to attract, 
develop, motivate and retain highly qualified and skilled employees. The loss of any of our senior management or key 
employees could materially adversely affect our ability to build on the efforts they have undertaken and to execute our business 
plan, and we may not be able to find adequate replacements. The market for highly skilled personnel is very competitive. We 
cannot ensure that we will be able to retain the services of any members of our senior management or other key employees. 
Furthermore, we have in the past and may in the future take measures in order to slow attrition. For example, to support 
retention of employees, in August 2022, we issued certain equity grants and repriced certain outstanding unvested stock 
options. If we do not succeed in attracting well-qualified employees, retaining and motivating existing employees in a cost-
effective manner, or engaging in succession planning, our business could be harmed.  

We Have and May Continue to Make Acquisitions and Investments, Which Could Result in Operating Difficulties, Dilution 
and Other Harmful Consequences. 

We continue to evaluate a wide array of potential strategic opportunities, including acquisitions and investments. For 

example, we acquired ShowingTime.com, Inc. in September 2021, VRX Media Group LLC in December 2022, Aryeo, Inc. in 
June 2023, Spruce Holdings, Inc. in September 2023, and Enchant, LLC, d/b/a Follow Up Boss, in December 2023. Any 
transactions that we enter into could be material to our financial condition and results of operation. The transactions we pursue 
may not result in the intended benefits to our business, and we may not successfully evaluate or utilize the acquired products, 
technology, or personnel, or accurately forecast the financial impact of an acquisition transaction. The process of closing a 
transaction and integrating an acquired company, business or technology could create unforeseen operating difficulties and 
expenditures. Potential risks include: diversion of management time and focus from operating our business to acquisition 
closing and integration challenges; customer and industry acceptance of products and services offered by the acquired 
company; implementation or remediation of controls, procedures and policies at the acquired company; compliance with 
differing laws and regulations applicable to international jurisdictions, if applicable; coordination of product, engineering and 
sales and marketing functions; retention of employees from the acquired company; liability for activities of the acquired 
company before the acquisition; litigation or other claims arising in connection with the acquired company; and impairment 
charges associated with goodwill and other acquired intangible assets. For example, we have recognized impairment charges 
related to certain acquired intangible assets in the past.  

Our failure to address these risks or problems encountered in connection with our past or future acquisitions and 
investments could cause us to fail to realize the anticipated benefits of such acquisitions or investments, incur unanticipated 
liabilities, and harm our business, results of operations and financial condition. 

Our Fraud Detection Processes and Information Security Systems May Not Successfully Detect All Fraudulent Activity by 
Third Parties Aimed at Our Employees or Customers, Which Could Adversely Affect Our Reputation and Business Results. 

Third-party actors have attempted in the past, and may attempt in the future, to conduct fraudulent activity by engaging 

with our customers by, for example, posting fake real estate and rental listings on our sites and attempting to solicit personal 
information or money from customers, and by engaging with our employees by, for example, making fake requests for transfer 
of funds or sensitive information. We make a large number of wire transfers in connection with loan and real estate closings and 
process sensitive personal data in connection with these transactions. We also enable certain rental transactions through our 
Zillow Rental Manager products, which may be separately subject to a risk of fraudulent activity. Though we have sophisticated 
fraud detection processes and have taken other measures to identify fraudulent activity on our mobile applications, websites and 
internal systems, we may not be able to detect and prevent all such activity. Similarly, the third parties we use to effectuate 
these transactions may fail to maintain adequate controls or systems to detect and prevent fraudulent activity. Persistent or 
pervasive fraudulent activity may cause customers and real estate partners to lose trust in us and decrease or terminate their 
usage of our products and services, or could result in financial loss, thereby harming our business and results of operations. 

20 

 
 
We Are Subject to Multiple Risks Related to the Credit Card and Debit Card Payments We Accept. 

We accept payments through credit and debit card transactions. For credit and debit card payments, we pay interchange 

and other fees, which may increase over time. An increase in those fees may require us to increase the prices we charge and 
increase our operating expenses, either of which could harm our business, financial condition and results of operations. 

We depend on processing vendors to complete credit and debit card transactions, both for payments owed to Zillow 
Group directly and for payments to other third parties, such as payments made between two third-party platform users such as 
renters and landlords in our rental payments product. If we or our processing vendors fail to maintain adequate systems for the 
authorization and processing of credit card transactions, it could cause one or more of the major credit card companies to 
disallow our continued use of their payment products. If these systems fail to work properly and, as a result, we do not charge 
our customers’ credit cards on a timely basis or at all, our business, revenue, results of operations and financial condition could 
be harmed. In addition, if we add, eliminate or change any of our processing vendors, we may experience processing 
disruptions and increased operating expenses, either of which could harm our business, financial condition, or results of 
operations. 

The payment methods that we offer also subject us to potential fraud and theft by criminals, who are becoming 

increasingly sophisticated, seeking to obtain unauthorized access to or exploit weaknesses that may exist in the payment 
systems. If we fail to comply with applicable rules or requirements for the payment methods we accept, or if payment-related 
data are compromised due to a breach of data, we may be liable for significant costs incurred by payment card issuing banks 
and other third parties or subject to fines and higher transaction fees, or our ability to accept or facilitate certain types of 
payments may be impaired. In addition, our customers could lose confidence in certain payment types, which may result in a 
shift to other payment types or potential changes to our payment systems that may result in higher costs. If we fail to adequately 
control fraudulent credit card transactions, we may face civil liability, diminished public perception of our security measures, 
and significantly higher credit card-related costs, each of which could harm our business, results of operations and financial 
condition. 

We are also subject to payment card association operating rules, certification requirements and rules governing electronic 

funds transfers, which could change or be reinterpreted to make it more difficult for us to comply. We are required to comply 
with payment card industry security standards. Failing to comply with those standards may violate payment card association 
operating rules, federal and state laws and regulations, and the terms of our contracts with payment processors. Any failure to 
comply fully also may subject us to fines, penalties, damages and civil liability, reputational risk and may result in the loss or 
impairment of our ability to accept credit and debit card payments. Further, there is no guarantee that such compliance will 
prevent illegal or improper use of our payment systems or the theft, loss, or misuse of data pertaining to credit and debit cards, 
card holders and transactions. 

If we are unable to maintain our chargeback rate or refund rates at acceptable levels, our processing vendors may increase 

our transaction fees or terminate their relationships with us. Any increases in our credit and debit card fees could harm our 
results of operations, particularly if we elect not to raise our rates for our service to offset the increase. The termination of our 
ability to process payments on any major credit or debit card could significantly impair our ability to operate our business. 

Some of Our Potential Losses May Not Be Covered by Insurance. We May Not Be Able to Obtain or Maintain Adequate 
Insurance Coverage. 

We maintain insurance to cover costs and losses from certain risk exposures in the ordinary course of our operations, but 

our insurance may not cover 100% of the costs and losses from all events. We are responsible for certain retentions and 
deductibles that vary by policy, and we may suffer losses that exceed our insurance coverage by a material amount. We may 
also incur costs or suffer losses arising from events against which we have no insurance coverage. In addition, large scale 
insurance market trends or the occurrence of adverse events in our business may raise our cost of procuring insurance or limit 
the amount or type of insurance we are able to secure. We may not be able to maintain our current coverage, or obtain new 
coverage in the future, on commercially reasonable terms or at all.  

21 

 
 
Our Business Subjects Us and Our Customers to Environmental Regulation, Which Creates Uncertainty Regarding Future 
Liabilities.  

Under various federal, state and local environmental laws, a current or previous owner or operator of real property may 

be liable for the cost of removing or remediating hazardous or toxic substances on such property. Such laws often impose 
liability whether or not the owner or operator knew of, or was responsible for, the presence of such hazardous or toxic 
substances. Even if more than one person may have been responsible for the contamination, each person covered by applicable 
environmental laws may be held responsible for all of the clean-up costs incurred. In addition, third parties may sue the owner 
or operator of a site for damages based on personal injury, natural resources or property damage or other costs, including 
investigation and clean-up costs, resulting from the environmental contamination. The presence of hazardous or toxic 
substances on one of our properties, including homes previously held in our inventory in connection with Zillow Offers 
operations, or the failure to properly remediate a contaminated property, could give rise to a lien in favor of the government for 
costs it may incur to address the contamination. A property owner who violates environmental laws may be subject to sanctions 
which may be enforced by governmental agencies or, in certain circumstances, private parties. The cost of defending against 
environmental claims, of compliance with environmental regulatory requirements or of remediating any contaminated property 
could materially and adversely affect us. 

Compliance with new or more stringent environmental and climate-related laws or regulations or stricter interpretation of 
existing laws may require material expenditures by us. We cannot assure you that future laws, ordinances or regulations will not 
impose any material environmental or other liability to us. In addition, we may be required to comply with various local, state 
and federal fire, health, life-safety and similar regulations. Failure to comply with applicable laws and regulations could result 
in fines and/or damages, suspension of personnel, civil liability or other sanctions. 

If Our Security Measures or Technology Systems, or Those of Third Parties Upon Which We Rely, Are Compromised, We 
May Be Subject to Legal Claims and Suffer Significant Losses, and Customers May Curtail Use of Our Products and 
Services and Our Real Estate Partners May Reduce or Eliminate Their Advertising on Our Mobile Applications and 
Websites. 

Our products and services involve the transmission, processing, and/or storage of users’ information, some of which may 

be private or include personally identifiable information such as social security numbers, financial account information, and 
credit card information. For example, our dotloop real estate transaction management software stores sensitive personal and 
financial information, our Mortech mortgage product and pricing software for mortgage professionals processes social security 
numbers, our rental applications product allows customers to obtain credit and background checks containing sensitive personal 
and financial information, and Zillow Home Loans, our mortgage origination business, and our real estate closings business, 
receive, handle and transmit highly sensitive personal and financial information about its customers. Cyber-attacks, malicious 
internet-based activity, online and offline fraud, administrative or technical failures and other similar activities threaten the 
confidentiality, integrity and availability of our information technology systems, including those of the third parties upon which 
we rely, and our sensitive data, including customer, employee and real estate partner data as well as intellectual property and 
other confidential business information, which could result in potential significant liability and litigation. Such threats are 
prevalent and continue to rise, are increasingly difficult to detect and come from a variety of sources, including traditional 
computer “hackers”, threat actors, “hacktivists”, organized criminal threat actors, personnel (such as through theft or misuse), 
sophisticated nation states and nation-state-supported actors. 

Some actors now engage and are expected to continue to engage in cyber-attacks, including without limitation nation-

state actors for geopolitical reasons and in conjunction with military conflicts and defense activities. During times of war and 
other major conflicts, we and the third parties upon which we rely may be vulnerable to a heightened risk of these attacks, 
including retaliatory cyber-attacks, that could materially disrupt our systems and operations, supply chain and ability to 
produce, sell and distribute our services. 

We and the third parties upon which we rely may be subject to a variety of evolving threats, including but not limited to 

social-engineering attacks (including through deep fakes, which may be increasingly more difficult to identify as fake, and 
phishing attacks), malicious code (such as viruses and worms), malware (including as a result of advanced persistent threat 
intrusions), denial-of-service attacks (such as credential stuffing), credential stuffing attacks, personnel misconduct or error, 

22 

 
 
ransomware attacks, supply-chain attacks, software bugs, server malfunctions, software or hardware failures, loss of data or 
other information technology assets, adware, telecommunications failures, earthquakes, fires, or floods, attacks enhanced or 
facilitated by AI,  and other similar threats. In particular, severe ransomware attacks are becoming increasingly prevalent and 
can lead to significant interruptions in our operations, impact our ability to provide our products or services, loss of sensitive 
data and income, reputational harm and diversion of funds. Extortion payments may alleviate the negative impact of a 
ransomware attack, but we may be unwilling or unable to make such payments due to, for example, applicable laws or 
regulations prohibiting such payments. 

Remote work has become more common and has increased risks to our information technology systems and data, as more 

of our employees utilize network connections, computers and devices outside our premises or network, including working at 
home, while in transit and in public locations. Additionally, future or past business transactions (such as acquisitions or 
integrations) could expose us to additional cybersecurity risks and vulnerabilities, as our systems could be negatively affected 
by vulnerabilities present in acquired or integrated entities’ systems and technologies. Outside parties may attempt to 
fraudulently induce employees, officers, directors, customers or real estate partners to disclose sensitive information in order to 
gain access to our information or our customers’ or real estate partners’ information, and our information technology and 
infrastructure may be vulnerable to attacks by hackers or breached due to user error, malfeasance or other disruptions. If we 
experience compromises to our security that result in the loss or unauthorized disclosure of confidential information, our 
customers and real estate partners may lose trust in us, customers may decrease the use of our mobile applications or websites 
or stop using our mobile applications, websites, or services in their entirety, real estate partners may decrease or stop 
advertising on our mobile applications or websites, and we may be subject to legal claims and liability, government 
investigation and additional state and federal legal requirements. If we experience compromises to our security that result in the 
loss of availability of our data, our mobile applications, websites, or services may be unable to function at a level necessary to 
meet our customers’ needs. 

Our reliance on vendors could introduce new cybersecurity risks and vulnerabilities, including supply-chain attacks, and 

other threats to our business operations. We engage a variety of vendors to process and store sensitive data, including certain 
customer information, some of which may be private or include personally identifiable information. We also depend on vendors 
to host many of the systems and infrastructure used to provide our products and services. Our ability to monitor these vendors’ 
information security practices is limited and these vendors may not have adequate information security measures in place. If our 
vendors experience a security incident or other interruption, we could experience adverse consequences, including harm to our 
business, results of operations and financial condition. Further, a security breach at our vendor could be perceived by customers 
or our real estate partners as a breach of our systems and could result in damage to our reputation and expose us to other losses. 
While we may be entitled to damages if our vendors fail to satisfy their privacy or security-related obligations to us, any award 
may be insufficient to cover our damages, or we may be unable to recover such award. In addition, supply-chain attacks have 
increased in frequency and severity, and we cannot guarantee that third parties’ infrastructure in our supply chain or our third-
party partners’ supply chains have not been compromised. 

Any of the previously identified or similar threats could cause a security incident or other interruption that could result in 
unauthorized, unlawful or accidental acquisition, modification, destruction, loss, alteration, encryption, disclosure of or access 
to our sensitive data of our information technology systems, or those of the third parties upon whom we rely. A security incident 
or other interruption could disrupt our ability (and that of third parties upon whom we rely) to provide our services. 

While we have security measures designed to protect against security incidents, there can be no assurance that these 
measures will be effective. Because the techniques used to obtain unauthorized access, disable or degrade service, or sabotage 
systems change frequently, often are not recognized until launched against a target, and may originate from less regulated and 
remote areas around the world, we may be unable to proactively address all these techniques or to implement adequate 
preventative measures. We take steps to detect and remediate vulnerabilities, but we may not be able to detect and remediate all 
vulnerabilities because the threats and techniques change frequently and are often sophisticated in nature. Therefore, such 
vulnerabilities could be exploited but may not be detected until after a security incident has occurred. Unremediated high risk or 
critical vulnerabilities pose material risks to our business. Further, we may experience delays in developing and deploying 
remedial measures designed to address any such identified vulnerabilities. 

23 

 
 
Applicable data privacy and security obligations may require us to notify relevant stakeholders of security incidents. Such 

disclosures are costly and the disclosure or the failure to comply with such requirements could lead to adverse consequences. 

If we (or a third party upon whom we rely) experience a security incident or are perceived to have experienced a security 

incident, we may experience adverse consequences. These consequences may include: government enforcement actions (for 
example, investigations, fines, penalties, audits and inspections); additional reporting requirements and/or oversight; restrictions 
on processing sensitive data (including personal data); litigation (including class action claims); indemnification obligations; 
negative publicity; reputational harm; monetary fund diversions; interruptions in our operations (including availability of data); 
financial loss and other similar harms. Any or all of these consequences could negatively impact our ability to attract new 
customers and increase engagement by existing customers, prevent or cause existing customers to stop using our products or 
services or close their accounts, or cause existing real estate partners to cancel their contracts, thereby harming our business, 
results of operations and financial condition. 

In addition to experiencing a security incident, third parties may gather, collect, or infer sensitive information about us 

from public sources, data brokers, or other means that reveals competitively sensitive details about our organization and could 
be used to undermine our competitive advantage or market position. Additionally, sensitive information of the Company or our 
customers could be leaked, disclosed, or revealed as a result of or in connection with our employee’s’, personnel’s, or vendor’s 
use of generative AI technologies. 

Our contracts may not contain limitations of liability, and even where they do, there can be no assurance that limitations 

of liability in our contracts are sufficient to protect us from liabilities, damages or claims related to our data privacy and 
information security obligations. We cannot be sure that our insurance coverage will be adequate or sufficient to protect us from 
or to mitigate liabilities arising out of our privacy and security practices, that such coverage will continue to be available on 
commercially reasonable terms or at all or that such coverage will pay future claims. 

Any Significant Disruption in Service on Our Mobile Applications or Websites or in Our Network Could Damage Our 
Reputation and Brands, and Result in a Loss of Customers of Our Products and Services and of Our Real Estate Partners, 
Which Could Harm Our Business, Results of Operations and Financial Condition. 

Our brand, reputation and ability to attract customers and real estate partners and deliver quality products and services 

depend on the reliable performance of our network infrastructure and content delivery processes. Our mobile applications and 
websites are exposed to attempts to overload our servers with denial-of-service attacks or similar disruptions from unauthorized 
use of our computer systems. We have experienced minor interruptions in these systems in the past, including server failures 
that temporarily slowed the performance of our mobile applications and websites, and we may experience interruptions in the 
future. Interruptions in these systems, whether due to system failures, computer viruses, software errors or physical or 
electronic break-ins, could affect the security or availability of our products and services on our mobile applications and 
websites and prevent or inhibit the ability of customers to access or effect transactions using our services. Since our customers 
may rely on our products and services, including our real estate transaction services and customer relationship management 
tools, for important aspects of their personal lives and businesses, problems with the reliability, availability or security of our 
systems could damage our customers’ businesses, harm our reputation, delay or inhibit a customer from completing a real estate 
transaction, result in a loss of customers of our products and services and of real estate partners and result in additional costs, 
any of which could harm our business, results of operations and financial condition. 

To deliver mobile and web Zillow Group brand content while ensuring scalability and redundancy, as well as internal 

support for our enterprise, we utilize both third-party web services for cloud computing and storage and shared data centers in 
various locations across the United States. 

We do not own or control the operation of certain of these facilities. Our systems and operations are vulnerable to damage 

or interruption from fire, flood, power loss, telecommunications failure, terrorist attacks, acts of war, electronic and physical 
break-ins, computer viruses, earthquakes and similar events. The occurrence of any of the foregoing events could result in 
damage to our systems and hardware or could cause them to fail completely, and our insurance may not cover such events or 
may be insufficient to compensate us for losses that may occur. 

24 

 
 
A failure of our systems at one site could result in reduced functionality for our customers, and a total failure of our 

systems could cause our mobile applications or websites to be inaccessible or for us to be unable to carry out day-to-day 
operations. Problems faced by our third-party web-hosting providers with the telecommunications network providers with 
which they contract or with the systems by which they allocate capacity among their customers, including us, could adversely 
affect the experience of our customers. Our third-party web-hosting providers could decide to close their facilities without 
adequate notice. Any financial difficulties, such as bankruptcy reorganization, faced by our third-party web-hosting providers or 
any of the service providers with whom they contract may have negative effects on our business, the nature and extent of which 
are difficult to predict. If our third-party web-hosting providers are unable to keep up with our growing needs for capacity, our 
customers, real estate partners and business could be harmed. In addition, if distribution channels for our mobile applications 
experience disruptions, such disruptions could adversely affect the ability of users and potential users to access or update our 
mobile applications, which could harm our business. 

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

We Rely Upon Certain Third-Party Services to Support Critical Functions of Our Business and Any Disruption of or 
Interference with our Use of those Third-Party Services Could Adversely Impact Our Operations and Our Business. 

A limited number of third-party services support essential functions of our business, including Amazon Web Services 
(“AWS”) and certain other cloud communications platform-as-a-service (“CPaaS”), Infrastructure-as-a-Service (“IaaS”) and 
Software-as-a-Service (“SaaS Services”) technologies hosted by third parties (together with CPaaS and IaaS, “Cloud 
Services”). AWS provides us with a distributed computing infrastructure platform for business operations, which is commonly 
referred to as a “cloud” computing service. Certain of our computer systems utilize data processing, storage capabilities and 
other services provided by AWS, and we currently run the vast majority of computing to power our mobile applications, 
websites, and other technology products and services on AWS, as our preferred cloud provider. In addition, we use Cloud 
Services to support important functions of our business, including enterprise resource planning, accounting, including revenue 
recognition, real estate transaction services, customer communications, and customer relationship management. We store a 
significant amount of information about our customers, real estate partners, employees, and business on AWS and in the Cloud 
Services, and we rely on these third-party service providers to provide services on a timely and effective basis. Their failure to 
perform as expected or as required by contract could result in significant disruptions and costs to our operations. In light of our 
reliance on AWS and Cloud Services, coupled with the complexity of obtaining replacement services, any disruption of, or  
interference with, or change in terms that impacts our use of or the cost to use these third-party services could adversely impact 
our operations and business. 

We Have and May Continue to be Subject to Outstanding Claims Related to Zillow Offers and Zillow Closing Services 
Following the Wind Down of their Respective Operations. 

We have and may in the future be subject to, claims, suits, government investigations, enforcement actions and 

proceedings arising from or related to Zillow Offers or Zillow Closing Services, including actions with respect to the purchase, 
renovation and resale of properties; Zillow Offers operations; Zillow Closing Services operations; and the subsequent wind 
down of operations, including those matters described in Part II, Item 8 in Note 16 under the subsection titled “Legal 
Proceedings. Regardless of the outcome, any such legal proceedings can have an adverse impact on us because of legal costs, 
diversion of management and other personnel, and other factors. In addition, it is possible that a resolution of one or more such 
proceedings could result in reputational harm, liability, fines, penalties, or sanctions, as well as judgments, consent decrees, or 
orders, which could in the future materially and adversely affect our business, operating results and financial condition.

Risks Related to Our Mortgages Business 

If Zillow Home Loans is Unable to Obtain and Maintain Sufficient Financing to Fund Its Origination of Mortgages or is 
Unable to Resell Mortgages on the Secondary Market, Our Mortgages Business and Financial Results May Suffer.  

Zillow Home Loans funds substantially all of its lending operations using warehouse and loan repurchase facilities, 
intending to sell substantially all loans and corresponding servicing rights to third-party financial institutions, government-
sponsored entities or mortgage servicing rights purchasers after a holding period. A substantial portion of the amounts available 
under these warehouse and loan repurchase facilities are not committed, meaning the applicable lender is not obligated to, but 
may in its discretion, advance loan funds beyond the committed amounts up to the maximum borrowing capacity. Zillow Home 
Loans’ borrowings are then generally repaid with the proceeds it receives from mortgage sales. To maintain and grow its 
business, Zillow Home Loans depends, in part, on having sufficient borrowing capacity under its current facilities or obtaining 
additional borrowing capacity under new facilities. If Zillow Home Loans is not able to negotiate with its lenders to advance 
loan funds beyond the committed amounts under its warehouse and repurchase facilities or to otherwise obtain and maintain 
debt financing with sufficient capacity or flexibility on acceptable terms, and does not have sufficient available cash on hand, 
then Zillow Home Loans may be unable to maintain or increase the volume of mortgage loans that it originates, may be limited 
in the type or quantity of loans it can fund, may lose customers to other mortgage lenders and its business may suffer. If Zillow 
Home Loans is unable to form or retain relationships with third-party financial institutions to purchase its loans or is unable to 
comply with any covenant in its agreements with these institutions, or is unable to do so on acceptable terms, it may be unable 
to sell its loans on the secondary market on favorable terms or at all. If Zillow Home Loans is unable to sell its loans or is 
required to repurchase the loans from third parties, it may be required to hold the loans for investment or sell them at a discount.  

Zillow Home Loans Product Offerings May Not Meet Customers’ Financing Needs, Which Could Cause Them to Use Other 
Lenders. 

Zillow Home Loans currently offers a number of mortgage products to customers including conventional conforming and 

non-conforming programs and government loan guarantee programs. Such offerings are subject to change based on various 
factors such as availability, business needs and customer demand. If these programs do not meet the financing needs of our 
customers, and we do not adapt to market changes and customer preferences, customers may opt to obtain financing from other 
lenders who offer different or more competitive rates or loan products. Similarly, if any of the government sponsored entities or 
government loan guarantee programs amend the terms of an existing loan program, cease offering the program, limit our ability 
to use the program or revoke the authority of Zillow Home Loans to offer such programs, we may have to make changes to or 
discontinue the mortgage products that we offer, which may negatively affect our business. 

Zillow Home Loans May Not Be Able to Continue to Grow its Mortgage Loan Origination Business, Which Could 
Negatively Affect Our Mortgages Business, Financial Condition and Results of Operations. 

The Zillow Home Loans mortgage loan origination business consists of providing purchase money loans to homebuyers 

and refinancing existing loans. The volume of originations of purchase money mortgage loans by Zillow Home Loans and 
future growth is impacted by, among other things, awareness of Zillow Home Loans and use of other Zillow products and 
services during the home buying and selling process. Changes to the other products and services that Zillow or its real estate 
partners provide may negatively impact demand for Zillow Home Loans. In addition, our ability to secure relationships with 
traditional business clients may influence our ability to grow our loan origination business. Our production and consumer direct 
lending operations are also subject to overall market factors that can impact our ability to grow our loan production volume. For 
example, volatile interest rates, affordability challenges, increased competition from new and existing market participants, 
reductions in the overall level of refinancing activity or slow growth in the level of new home purchase activity can impact our 
ability to continue to grow our loan production volumes, and we may be forced to accept lower margins in our respective 
businesses in order to continue to compete and keep our volume of activity consistent with past or projected levels. If we are 
unable to continue to grow our loan origination business, this could adversely affect our business. 

26 

 
 
 
 
Zillow Home Loans Is Dependent on United States Government-Sponsored Entities and Government Agencies, and Any 
Actions by These Entities or Changes in These Entities or Their Operations Could Adversely Affect Our Mortgage Business, 
Liquidity, Financial Condition and Results of Operations. 

The ability of Zillow Home Loans to generate revenue through loan sales depends, in part, on its participation in 
programs administered by government agencies such as the United States Department of Housing and Urban Development’s 
Federal Housing Administration, the United States Department of Veterans Affairs, the United States Department of 
Agriculture, or government-sponsored entities (“GSEs”) such as the Federal National Mortgage Association (“Fannie Mae”) or 
the Federal Home Loan Mortgage Corporation (“Freddie Mac”). Presently, some of the loans Zillow Home Loans originates are 
sold on a direct basis to a GSE, while others are sold “whole loan” to individual investors on the secondary market. If any of 
these government agencies or GSEs limit Zillow Home Loans’ ability to participate in any of these programs, or if the operation 
of any of these government agencies or GSEs or the programs they administer are eliminated or changed, our mortgages 
business, liquidity, financial condition, and results of operations may be adversely affected.  

A number of legislative proposals have been introduced in recent years that would wind down or phase out the GSEs, 
including proposals to end the conservatorship and privatize Fannie Mae and Freddie Mac. It is not possible to predict the scope 
and nature of the actions that the United States government, including the current administration, will ultimately take with 
respect to the GSEs. Any changes in laws and regulations affecting the relationship between Fannie Mae and Freddie Mac and 
their regulators or the United States federal government, and any changes in leadership at any of these entities could adversely 
affect our mortgages business and prospects. Any discontinuation of, or significant reduction in, the operation of Fannie Mae or 
Freddie Mac or any significant adverse change in their capital structure, financial condition, activity levels in the primary or 
secondary mortgage markets or underwriting criteria could materially and adversely affect our mortgages business, liquidity, 
financial condition, and results of operations. A discontinuation or reduction in the operations of the GSEs could also affect 
“whole loan” sales on the secondary market, as there is a potential that this could cause a sharp decline in investor appetite. 

Zillow Home Loans Operates in a Highly Regulated Industry, and Federal, State, and Local Laws and Regulations, 
Including Many That Are Continually Changing, Could Materially and Adversely Affect Our Business, Financial Condition 
and Results of Operations. 

Zillow Home Loans is required to comply with a wide array of federal, state and local laws and regulations that regulate, 
among other things, the manner in which it conducts its loan origination business. These regulations directly impact the Zillow 
Home Loans business and require constant compliance, monitoring and internal and external audits.  

Zillow Home Loans’ failure to operate effectively and in compliance with these laws, regulations and rules could subject 

us to lawsuits or governmental actions and damage our reputation, which could materially and adversely affect our business, 
financial condition and results of operations. For example, Zillow Home Loans’ failure to comply with these laws, regulations 
and rules may result in increased costs of doing business, changes to the way we operate our business, reduced payments by 
borrowers, modification of the original terms of loans, permanent forgiveness of debt, delays in the foreclosure process, 
forfeiture or refunds on fees collected on loan originations, increased servicing advances, litigation, reputational damage, 
enforcement actions, and repurchase and indemnification obligations.   

In addition, Zillow Homes Loans must ensure that our lending operations serve consumers in accordance with a variety of 

federal and state fair lending laws and regulations, including without limitation the Fair Housing Act, the Equal Credit 
Opportunity Act, the Home Mortgage Disclosure Act, and the prohibition against engaging in Unfair, Deceptive, or Abusive 
Acts or Practices pursuant to the Dodd-Frank Act, Federal Trade Commission Act, and state corollaries. Our inability to conduct 
our lending operations in compliance with fair lending laws and regulations may expose Zillow Home Loans to regulatory 
action, litigation, and reputational damage, among other things. 

Our Mortgages Business is Impacted by Interest Rates. Changes in Prevailing Interest Rates May Have an Adverse Effect 
on Our Financial Results. 

Our financial performance is directly affected by changes in prevailing interest rates and home prices, which in turn, 

impact the affordability of a home. Our financial performance may be adversely affected or be subject to substantial volatility 

27 

 
 
because of changes in prevailing interest rates, which may be impacted by a number of factors. For example, in recent years, 
due to inflationary pressures, there was an increased degree of uncertainty and unpredictability concerning current interest rates, 
future interest rates and potential negative interest rates, which had an adverse effect on the results of operations.  

Consumer demand for certain mortgage products and loan types are frequently driven by changes in market conditions, 

interest rates, lender fees, and other transaction costs. If interest rates continue to rise or remain elevated, our business could be 
adversely affected if we are unable to increase our share of purchase mortgages or if affordability challenges contract the total 
addressable market. In either case, our mortgage origination business and our financial results could be harmed.  

Zillow Home Loans uses derivatives and other instruments to reduce exposure to adverse changes in interest rates. 
Hedging interest rate risk is a complex process, requiring sophisticated models and constant monitoring. Zillow Home Loans’ 
hedging activity may fail to provide adequate coverage for interest rate exposure due to market volatility, hedging instruments 
that do not directly correlate with the interest rate risk exposure being hedged or counterparty defaults on obligations. Certain of 
our hedges related to newly originated mortgages may be subject to margin calls, which, if made, could adversely impact our 
liquidity. There may be periods during which Zillow Home Loans elects not to hedge some or all of its interest rate risk. 

Risks Related to Our Intellectual Property 

We May Be Unable to Adequately Protect Our Intellectual Property, Which Could Harm the Value of Our Brands and Our 
Business. 

We regard our intellectual property as critical to our success, and we rely on trademark, copyright and patent law, trade 
secret protection and contracts to protect our proprietary rights. If we are not successful in protecting our intellectual property, 
the value of our brands and our business, results of operations and financial condition could be harmed. 

While we believe that our issued patents and pending patent applications help to protect our business, we cannot ensure 

that our operations do not, or will not, infringe valid, enforceable patents of third parties or that competitors will not devise new 
methods of competing with us that are not covered by our patents or patent applications. We cannot ensure that our patent 
applications will be approved, that any patents issued will adequately protect our intellectual property, that such patents will not 
be challenged by third parties or found to be invalid or unenforceable, or that our patents will be effective in preventing third 
parties from utilizing a “copycat” business model to offer the same products or services. Aspects of the technology underlying 
our Zestimate home valuation model, for example, which we consider to be a trade secret affording us a key competitive 
advantage with respect to customer engagement, is currently protected by patents, the loss of which could benefit comparable 
services provided by our competitors and result in decreased user traffic and engagement with our mobile applications and 
websites, thereby harming our results of operations and financial condition. In addition to our patented technology, our 
Zestimate home valuation model uses a significant amount of proprietary, trade secret methodology. Any accidental disclosure, 
or disclosure in response to litigation or regulatory inquiries that do not include confidential information protection could harm 
our competitive advantage.  

Effective trademark, service mark, copyright and trade secret protection may not be available in every country in which 

our products and services may be provided. The laws of certain countries do not protect proprietary rights to the same extent as 
the laws of the United States and, therefore, in certain jurisdictions, we may be unable to protect intellectual property and our 
proprietary technology adequately against unauthorized third-party copying or use, which could harm our competitive position. 
We have licensed in the past, and expect to license in the future, certain of our proprietary rights, such as trademarks or 
copyrighted material, to third parties. These licensees may take actions that might diminish the value of our proprietary rights or 
harm our reputation, even if we have agreements prohibiting such activity. Though certain of these third parties are obligated to 
indemnify us for breaches of our intellectual property rights, they may be unable to meet these obligations. In addition, we rely 
on intellectual property and technology developed or licensed by third parties, and we may not be able to obtain licenses and 
technologies from these third parties on reasonable terms or at all. Any of these events could harm our business, results of 
operations or financial condition. 

In addition, we may actively pursue entities that infringe our intellectual property, including through legal action. Taking 

such action may be costly, and we cannot ensure that such actions will be successful. Any increase in the unauthorized use of 

28 

 
 
our intellectual property could make it more expensive for us to do business and harm our results of operations or financial 
condition. Similarly, we may not be able to adequately protect innovations resulting from generative artificial intelligence 
(“AI”) due to existing copyright and patent laws. 

Intellectual Property Disputes Are Costly to Defend and Could Harm Our Business, Results of Operations, Financial 
Condition and Reputation. 

From time to time, we face allegations that we have infringed the trademarks, copyrights, patents and other intellectual 

property rights of third parties. If we are not successful in defending ourselves against these claims, we may be required to pay 
damages and may be subject to injunctions, each of which could harm our business, results of operations, financial condition 
and reputation. As we grow our business and expand our operations, we expect that we will continue to be subject to intellectual 
property claims and allegations. Patent and other intellectual property disputes or litigation may be protracted and expensive, 
and the results are difficult to predict and may require us to stop offering certain products, services or features, purchase 
licenses that may be expensive to procure, or modify our products or services. In addition, patent or other intellectual property 
disputes or litigation may result in significant settlement costs. Any of these events could harm our business, results of 
operations, financial condition and reputation. 

In addition, we use open source software in our services and will continue to use open source software in the future. From 

time to time, we may be subject to claims brought against companies that incorporate open source software into their products 
or services, claiming ownership of, or demanding release of, the source code, the open source software and/or derivative works 
that were developed using such software, or otherwise seeking to enforce the terms of the applicable open source license. These 
claims could also result in litigation, and we may be required to purchase a costly license or remove open source software, 
devote additional research and development resources to changing our products or services, make generally available the source 
code for our proprietary technology, or waive certain of our intellectual property rights, any of which would have a negative 
effect on our business and results of operations. 

Even if these matters do not result in litigation or are resolved in our favor or without significant cash settlements, the 

time and resources necessary to resolve them could harm our business, results of operations, financial condition and reputation. 

We May Be Unable to Continue to Use the Domain Names That We Use in Our Business, or Prevent Third Parties From 
Acquiring and Using Domain Names That Infringe on, Are Similar to, or Otherwise Decrease the Value of Our Brand or 
Our Trademarks or Service Marks. 

We have registered domain names for our websites that we use in our business. If we lose the ability to use a domain 
name, we may incur significant expenses to market our products and services under a new domain name, which could harm our 
business. In addition, our competitors could attempt to capitalize on our brand recognition by using domain names similar to 
ours. Domain names similar to ours have been registered in the United States and elsewhere. We may be unable to prevent third 
parties from acquiring and using domain names that infringe on, are similar to, or otherwise decrease the value of our brand or 
our trademarks or service marks. Protecting and enforcing our rights in our domain names and determining the rights of others 
may require litigation, which could result in substantial costs and diversion of management’s attention. 

Proprietary Rights Agreements With Employees and Others May Not Adequately Prevent Disclosure of Trade Secrets and 
Other Proprietary Information. 

In order to protect our technologies and strategic business and operations information, we rely in part on proprietary 
rights agreements and other assignment provisions with our employees, independent contractors, vendors, licensees, and other 
third parties. These agreements may not be enough to fully mitigate the possibility of inadvertent disclosure of confidential 
information, including trade secrets, and may not provide an adequate remedy in the event of unauthorized disclosure of 
confidential information. The loss of trade secret protection could make it easier for third parties to compete with our products 
by copying functionality. Others may independently discover our trade secrets and proprietary information, and in such cases, 
we could not assert any trade secret rights against such parties. Further, if our employees, contractors or other third parties with 
whom we do business use intellectual property owned by others in their work for us, disputes may arise as to the rights in 
related or resulting know-how and inventions. Any changes in, or unfavorable interpretations of, intellectual property laws may 

29 

 
 
compromise our ability to enforce our trade secret and intellectual property rights. Costly and time-consuming litigation could 
be necessary to enforce and determine the scope of our proprietary rights, and failure to obtain or maintain protection of our 
trade secrets or other proprietary information could harm our business, results of operations, reputation and competitive 
position. 

We May Not Be Able to Halt the Operations of Websites That Aggregate or Misappropriate Our Data. 

From time to time, third parties have misappropriated our data through website scraping, robots or other means, and 
aggregated this data on their websites with data from other companies. In addition, copycat websites have misappropriated data 
on our network and attempted to imitate our brand or the functionality of our websites. When we have become aware of such 
websites, we have employed technological or legal measures in an attempt to halt their operations. We may not be able, 
however, to detect all such websites in a timely manner and, even if we could, technological and legal measures may be 
insufficient to halt their operations. In some cases, particularly in the case of websites operating outside of the United States, 
our available remedies may not be adequate to protect us against the impact of the operation of such websites. In addition, if 
such activity creates confusion among customers or real estate partners, our brands and business could be harmed. This 
misappropriation of data may also harm our relationships with any third party data providers who originally licensed the data to 
us, including potentially breaching our agreements with these third parties depending on the terms of each license agreement. 
Regardless of whether we can successfully enforce our rights against the operators of these websites, any measures that we may 
take could require us to expend significant financial or other resources, which could harm our business, results of operations or 
financial condition. 

Risks Related to Regulatory Compliance and Legal Matters 

Failure to Comply with Federal, State and Local Laws, Rules and Regulations or to Obtain and Maintain Required Licenses 
or Authorizations, Could Materially and Adversely Affect our Business, Financial Condition and Results of Operations.  

We provide products and services to customers and real estate partners in heavily regulated industries through a number 

of different channels across the United States and to some extent, in Canada. As a result, we are currently subject to a variety of, 
and may in the future become subject to additional or newly enacted, international, federal, state and local laws and regulations 
in various jurisdictions, which are subject to change at any time, including laws regarding the real estate, rental, mortgage and 
insurance industries, mobile and internet based businesses and other businesses that rely on advertising, as well as privacy, data 
security, and consumer protection laws, and employment laws. These laws are complex and can be costly to comply with, 
require significant management time and effort, and subject us to claims, government enforcement actions, civil and criminal 
liability or other remedies, including suspension of business operations. These laws may conflict with each other, and if we 
comply with the laws of one jurisdiction, it may require us to adjust our practices in other jurisdictions. Our distributed 
workforce may subject us to employment laws, including employment taxes, in many states and localities in the United States 
and certain foreign jurisdictions, and may increase the costs and expenses we incur to comply with or seek compliance with 
these laws. In addition, contingent workers engaged by the Company throughout the United States and other current and future 
global locations may subject us to laws and taxes in those jurisdictions and may increase the costs and expenses we incur to 
comply with applicable laws and maintain adequate protection of our rights, including intellectual property rights.  

In addition, by providing a medium through which users can post content and communicate with one another, we may 

also be subject to laws governing intellectual property ownership, obscenity, libel, discrimination/hate speech, tenant screening, 
and privacy, among other issues. The real estate agents, mortgage professionals, banks, property managers, rental agents and 
certain of our other customers and advertisers are subject to various state and federal laws and regulations, including, but not 
limited to those relating to real estate, rentals and mortgages, which may impact their use of our mobile applications and 
websites. We cannot ensure that these entities will comply with applicable laws and regulations, including any future changes to 
those laws and regulations, at all times. We endeavor to ensure that any content displayed by Zillow Group is consistent with 
such laws and regulations by obtaining assurances of compliance from our advertisers and customers for their activities 
through, and the content they provide on, our mobile applications and websites. 

30 

 
 
In connection with the real estate transaction products and services that we provide, we maintain real estate brokerage, 
title and escrow, mortgage broker, insurance agent/producer and mortgage lender licenses in the markets in which we operate 
those regulated products and services. Certain of our mortgage marketing products are operated by our wholly owned 
subsidiary, Zillow Group Marketplace, Inc., a licensed mortgage broker, and we originate residential mortgages through Zillow 
Home Loans, a licensed mortgage lender. Zillow Group Marketplace, Inc. and Zillow Home Loans are subject to stringent state 
and federal laws and regulations and to the scrutiny of state and federal government agencies as a licensed mortgage broker and 
licensed mortgage lender, respectively. Mortgage products are regulated at the state level by licensing authorities and 
administrative agencies, and also by the CFPB and other federal agencies. These laws generally regulate the manner in which 
lending and lending-related activities are marketed or made available, including advertising and other consumer disclosures, 
payments for services and record keeping requirements; these laws include but are not limited to the Real Estate Settlement 
Procedures Act, the Fair Credit Reporting Act, the Truth in Lending Act, the Equal Credit Opportunity Act, the Fair Housing 
Act, the Dodd-Frank Wall Street Reform and Consumer Protection Act and various federal, state and local laws. The CFPB and 
FTC also have broad authority to enforce prohibitions on practices that it deems to be unfair, deceptive or abusive. 

The growing regulatory focus, in particular by the CFPB, on artificial intelligence/automated underwriting, digital 
mortgage comparison shopping platforms, dark patterns, property valuation and marketing models, coupled with rapidly 
changing fair housing and fair lending enforcement priorities by the CFPB and other regulators may impact our ability to adapt 
our business and maintain compliance, which may affect our business operations, financial condition or results of operations. 
State laws may restrict the amount and nature of interest and fees that may be charged by a lender or mortgage broker, or 
otherwise regulate the manner in which lenders or mortgage brokers operate or advertise. 

We hold real estate brokerage licenses through multiple entities in multiple states and may apply for additional real estate 

brokerage licenses as needed to support our business. To maintain these licenses, we must comply with the requirements 
governing licensed real estate activities and brokerage-related businesses in the markets where we operate. We may be subject 
to additional local, state and federal laws and regulations governing residential real estate transactions, including those 
administered by the Department of Housing and Urban Development (“HUD”), and the states and municipalities in which we 
transact. Further, due to the geographic scope of our operations and the nature of the services we provide, certain of our other 
subsidiaries maintain title and escrow licenses in certain states in which we operate. 

A number of our personnel are required to maintain individual real estate agent or broker licenses, title and escrow agent 

licenses, insurance agent/producer, mortgage broker, mortgage loan originator licenses and mortgage lender licenses. In 
addition, for certain company licenses that we hold, we are required to designate individual licensed brokers of record, qualified 
individuals and control persons. We cannot assure you that we, or our licensed personnel, are and will remain at all times, in full 
compliance with real estate, title and escrow, insurance and mortgage licensing and consumer protection laws and regulations 
and we may be subject to fines or penalties in the event of any non-compliance. If we, or our licensed personnel, apply for new 
licenses, we may become subject to additional licensing requirements, which we may not be in compliance with at all times. If 
in the future a state agency were to determine that we, or our licensed personnel, are required to obtain additional licenses in 
that state in order to operate our business, or if we or our licensed personnel lose or do not renew an existing license or are 
otherwise found to be in violation of a law or regulation, we or our licensed personnel may be subject to fines or legal penalties, 
lawsuits, enforcement actions, void contracts, or our business operations in that state may be suspended or prohibited. 
Compliance with these laws and regulations is complicated and costly and may inhibit our ability to innovate or grow.  

Zillow Home Loans operates its Federal Housing Administration loan program under authority granted by HUD. In the 

event that HUD determines that Zillow Home Loans has failed or refused to comply with all relevant terms and conditions 
necessary to maintain its authority active and in good standing, then such authority could be suspended, revoked or materially 
altered, which would materially and adversely affect the ability of Zillow Home Loans to conduct its business.  

If we are unable to comply with these laws or regulations in a cost-effective manner, we may modify impacted products 
and services, which could require a substantial investment and loss of revenue, or require that we cease providing the impacted 
product or service altogether. If we are found to have violated laws or regulations, we may be subject to significant fines, 
penalties, and other losses. 

31 

 
 
We Are Subject to Stringent and Evolving Laws, Regulations, Rules, Contractual Obligations, Policies and Other 
Obligations Related to Data Privacy and Security in the United States and Canada and May Be Subject to Similar Data 
Privacy and Security Obligations in Other Jurisdictions Where We Have Operations and/or Vendors. Our Actual or 
Perceived Failure to Comply With Such Obligations Could Lead to Regulatory Investigations or Actions; Litigation 
(Including Class Claims) and Mass Arbitration Demands; Fines and Penalties; Disruptions of Our Business Operations; 
Reputational Harm; Loss of Revenue or Profits; Loss of Customers and Other Adverse Business Consequences. 

In the ordinary course of business, we collect, receive, store, process, generate, use, transfer, disclose, make accessible, 

protect, secure, dispose of, transmit, and share (collectively, processing) personal data and other sensitive data, which may 
include proprietary and confidential business data, trade secrets, intellectual property, sensitive third-party data, business plans, 
transactions, social security numbers, financial account information, and credit card information. 

Our data processing activities subject us to numerous data privacy and security obligations, such as various laws, 
regulations, guidance, industry standards, external and internal privacy and security policies, contractual requirements, and 
other obligations relating to data privacy and security. 

In the United States, federal, state, and local governments have enacted numerous data privacy and security laws, 
including data breach notification laws, personal data privacy laws, consumer protection laws (e.g., Section 5 of the Federal 
Trade Commission Act), and other similar laws (e.g., wiretapping laws). For example, the California Consumer Privacy Act of 
2018, as amended by the California Privacy Rights Act of 2020 (“CPRA”), (collectively, “CCPA”) applies to personal 
information of consumers, business representatives, and employees who are California residents, and requires businesses to 
provide specific disclosures in privacy notices and honor requests of California residents to exercise certain privacy rights, such 
as those noted below. The CCPA provides for civil penalties of up to $7,500 per violation and allows private litigants affected 
by certain data breaches to recover significant statutory damages. In addition, the CPRA expanded the CCPA’s requirements, 
including by adding a new right for individuals to correct their personal information and establishing a new regulatory agency 
to implement and enforce the law. 

Other states, such as Virginia, Colorado, Connecticut and Utah, have also passed comprehensive privacy laws, and 

similar laws are being considered in several other states, as well as at the federal and local levels. These state laws and the 
CCPA provide individuals with certain rights concerning their personal information, including the right to access, correct, or 
delete certain personal information, and opt-out of certain data processing activities, such as targeted advertising, profiling, and 
automated decision-making. The exercise of these rights may impact our business and ability to provide our products and 
services. We also have operations outside of the United States, including in Canada, and Canada’s Personal Information 
Protection and Electronic Documents Act (“PIPEDA”) imposes strict requirements for processing personal data and there are 
also various provincial and territorial privacy laws that govern the protection of personal data. These developments may further 
complicate compliance efforts and may increase legal risk and compliance costs for us and the third parties upon whom we rely. 

Additionally, laws, regulations, and standards covering marketing and advertising activities conducted by telephone, 
email, mobile devices, and the internet, may be applicable to our business, such as the Telephone Consumer Protection Act, the 
Telemarketing Sales Rule, the Controlling the Assault of Non-Solicited Pornography and Marketing Act, and similar state 
consumer protection laws, as well as requirements imposed by private parties such as telecommunications carriers. We also 
assist with the processing of customer credit card transactions and consumer credit report requests, originate mortgage loans, 
perform real estate closings and provide other product offerings, which results in us receiving or facilitating transmission of 
personally identifiable information. Processing of this type of information is increasingly subject to legislation and regulation in 
the United States, including under the Fair Credit Reporting Act and the Gramm-Leach-Bliley Act. These laws and regulations 
are generally intended to protect the privacy and security of personal information, including credit card information that is 
collected, processed and transmitted. We could be adversely affected if government regulations require us to significantly 
change our business practices with respect to this type of information or if the third parties that we engage with to provide 
processing and screening services violate applicable laws and regulations. Further, restrictions implemented on the platforms 
through which our websites and applications are accessed, such as mobile operating systems, may impede the effectiveness of 
our marketing efforts and ability to measure the effectiveness of those efforts, reducing our ability to market our products and 
services and grow our customer base. A number of states have in place laws regulating the interception of electronic

communications; if a court were to conclude that our monitoring of user activity violates such laws, our ability to understand 
our customers, and therefore the effectiveness of our product offerings and marketing efforts, could be reduced. 

Our employees and personnel use generative AI technologies to perform their work, and the disclosure and use of 

personal information in generative AI technologies is subject to various privacy laws and other privacy obligations. 
Governments have passed and are likely to pass additional laws regulating generative AI. Our use of this technology could 
result in additional compliance costs, regulatory investigations and actions, copyright infringement claims, and consumer 
lawsuits. If we are unable to use generative AI, it could make our business less efficient and result in competitive disadvantages. 

In addition to data privacy and security laws, we may be contractually subject to industry standards adopted by industry 

groups and may become subject to such obligations in the future. We may also be bound by other contractual obligations related 
to data privacy and security, and our efforts to comply with such obligations may not be successful. For example, we may be 
subject to the Payment Card Industry Data Security Standard (“PCI DSS”) requirements. The PCI DSS requires companies to 
adopt certain measures to ensure the security of cardholder information, including using and maintaining firewalls, adopting 
proper password protections for certain devices and software, and restricting data access. Noncompliance with PCI-DSS can 
result in penalties ranging from $5,000 to $100,000 per month by credit card companies, litigation, damage to our reputation, 
and revenue losses. We may also rely on vendors to process payment card data; those vendors may be subject to PCI DSS, and 
our business may be negatively affected if our vendors are fined or suffer other consequences as a result of PCI DSS 
noncompliance. 

We may publish privacy notices, marketing materials, and other statements, such as compliance with certain certifications 

or self-regulatory principles, regarding data privacy and security. If these policies, materials or statements are found to be 
deficient, lacking in transparency, deceptive, unfair, or misrepresentative of our practices, we may be subject to investigation, 
enforcement actions by regulators, or other adverse consequences. 

Obligations related to data privacy and security (and consumers’ data privacy expectations) are quickly changing, 

becoming increasingly stringent, and creating uncertainty. Additionally, these obligations may be subject to differing 
applications and interpretations, which may be inconsistent or conflict among jurisdictions. Preparing for and complying with 
these obligations requires us to devote significant resources and may necessitate changes to our services, information 
technologies, systems, and practices and to those of any third parties that process personal data on our behalf. 

We may at times fail (or be perceived to have failed) in our efforts to comply with our data privacy and security 
obligations. Moreover, despite our efforts, our personnel or third parties on whom we rely may fail to comply with such 
obligations, which could negatively impact our business operations. If we or the third parties on which we rely fail, or are 
perceived to have failed, to address or comply with applicable data privacy and security obligations, we could face significant 
consequences, including but not limited to: government enforcement actions (e.g., investigations, fines, penalties, audits, 
inspections, and similar); litigation (including class-action claims) and mass arbitration demands; additional reporting 
requirements and/or oversight; bans on processing personal data; and orders to destroy or not use personal data. In particular, 
plaintiffs have become increasingly more active in bringing privacy-related claims against companies, including class claims 
and mass arbitration demands. Some of these claims allow for the recovery of statutory damages on a per violation basis, and, if 
viable, carry the potential for monumental statutory damages, depending on the volume of data and the number of violations. 
Any of these events could have a material adverse effect on our reputation, business, or financial condition, including but not 
limited to: loss of customers; inability to process personal data or to operate in certain jurisdictions; limited ability to develop or 
commercialize our products and services; expenditure of time and resources to defend any claim or inquiry; adverse publicity; 
or substantial changes to our business model or operations. 

We are From Time to Time Involved In, or May in the Future be Subject to, Claims, Suits, Government Investigations, and 
Other Proceedings That May Result in Adverse Outcomes. 

We are from time to time involved in, or may in the future be subject to, claims, suits, government investigations, 
enforcement actions and proceedings arising from our business, including actions with respect to intellectual property, privacy, 
consumer protection, information security, mortgage brokering, mortgage origination, real estate, real estate brokerage, 
environmental, data protection, antitrust, the Real Estate Settlement Procedures Act of 1974 (RESPA), fair housing or fair 

33 

 
 
lending, compliance with securities laws, or law enforcement matters, tax matters, labor and employment, and commercial 
claims, as well as actions involving content generated by our customers, shareholder derivative actions, purported class action 
lawsuits, and other matters, including those matters described in Part II, Item 8 in Note 16 under the subsection titled “Legal 
Proceedings” in our Notes to Consolidated Financial Statements in this Annual Report on Form 10-K. Such claims, suits, 
government investigations, and proceedings are inherently uncertain, and their results cannot be predicted with certainty. 
Regardless of the outcome, any such legal proceedings can have an adverse impact on us because of legal costs, diversion of 
management and other personnel, and other factors. In addition, it is possible that a resolution of one or more such proceedings 
could result in reputational harm, liability, fines, penalties, or sanctions, as well as judgments, consent decrees, or orders 
preventing us from offering certain features, functionalities, products, or services, or requiring a change in our business 
practices, products or technologies, which could in the future materially and adversely affect our business, operating results and 
financial condition. 

In some instances, third parties may have an obligation to indemnify us for liabilities related to litigation or governmental 
investigations, and they may be unable to, or fail to, fulfill such obligations. If such third parties failed to indemnify us, we may 
be financially responsible, which could adversely affect our financial condition and cash flow.  

Risks Related to Our Financial Position(cid:3)

We Incurred Significant Operating Losses in the Past and We May Not Be Able to Generate Sufficient Revenue to Be 
Profitable Over the Long Term. 

We have incurred significant net operating losses in the past and, as of December 31, 2023, we had an accumulated 
deficit of $1.8 billion. It is possible that our growth rate may decline in the future as the result of a variety of factors, including 
the maturation of our business or if we are unable to successfully execute on our growth strategy. At the same time, we also 
expect certain of our costs to increase in future periods as we continue to expend substantial financial resources to develop and 
expand our business, which may include: 

• 
• 
• 
• 
• 
• 

expansion of Zillow Home Loans; 
product and services development; 
sales and marketing; 
technology infrastructure; 
strategic opportunities, including commercial relationships and acquisitions; and 
general and administrative expenses, including legal and accounting expenses related to being a public company. 

These investments may not result in increased revenue or growth in our business. If we fail to continue to grow our 
revenue and overall business and to manage our expenses, we may incur significant losses in the future and not be able to 
achieve or maintain profitability. 

A failure by Zillow Home Loans to operate at a profit could also place its Federal Housing Administration Title II lender 
authorization in jeopardy, adversely impact our relationship with Fannie Mae and Freddie Mac, limit our ability to sell loans to 
third party financial institutions and may adversely impact our ability to utilize our loan repurchase facilities and warehouse 
lines of credit. Any such adverse impacts could threaten Zillow Home Loans’ ability to continue operations. 

Servicing Our Debt Requires a Significant Amount of Cash, and We May Not Have Sufficient Cash Flow From Our 
Business to Pay Our Substantial Debt, Settle Conversions of Our Convertible Senior Notes, or Repurchase Our Convertible 
Senior Notes Upon a Fundamental Change. 

We utilize several forms of debt to provide capital for the continued growth and operation of our business, such as 
tranches of convertible senior notes and warehouse and repurchase facilities for Zillow Home Loans. Our indebtedness includes 
$608 million aggregate principal amount under our Convertible Senior Notes due in 2024 (the “2024 Notes”), $507 million 
aggregate principal amount under our Convertible Senior Notes due in 2025 (the “2025 Notes”), $499 million aggregate 
principal amount under our Convertible Senior Notes due in 2026 (the “2026 Notes”), and mortgage credit facilities (aggregate 
maximum borrowing capacity of $250 million as of December 31, 2023). Our ability to make payments on the principal of, to 

34 

 
 
pay interest on, or to refinance our indebtedness depends on our future performance and, if applicable, the value of collateral, 
which is subject to economic, industry, competitive and other factors beyond our control. Our business may not continue to 
generate cash flow from operations in the future sufficient to service our debt and make necessary capital expenditures. If we 
are unable to generate such cash flow, we may be required to adopt one or more alternatives, such as selling assets, 
restructuring debt or obtaining additional equity capital on terms that may be onerous or highly dilutive. Our ability to extend or 
refinance our indebtedness will depend on the capital markets and our financial condition at such time. We may not be able to 
engage in any of these activities or engage in these activities on desirable terms, which could result in a default on our debt 
obligations, including our convertible senior notes, credit facilities, or otherwise. 

Holders of our convertible senior notes have the right to require us to repurchase their notes upon the occurrence of a 

fundamental change at a repurchase price equal to 100% of the principal amount of the notes to be repurchased, plus accrued 
and unpaid interest. Holders of our convertible senior notes may elect to convert their notes at various times and pursuant to 
specific circumstances, as provided in the corresponding indenture. When such an election is made, we may opt to settle any 
such conversion by delivering solely shares of our Class C capital stock, solely cash payments, or a combination of Class C 
capital stock and cash payments after consideration of various factors, including the price of our Class C capital stock, market 
factors, liquidity, and the needs of our business. Upon conversion of our convertible senior notes, unless we elect to deliver 
solely shares of our Class C capital stock to settle such conversion (other than paying cash in lieu of delivering any fractional 
shares), we will be required to make cash payments in respect of the notes being converted. We may not have enough available 
cash or be able to obtain financing at the time we are required to make repurchases of the notes surrendered therefore or at the 
time the notes are being converted. Our failure to repurchase our convertible senior notes at a time when the repurchase is 
required by the indenture or to pay any cash payable on future conversions of the notes would constitute an event of default. If 
the repayment of any indebtedness were to be accelerated because of such event of default (whether under the notes or 
otherwise), we may not have sufficient funds to repay the indebtedness and repurchase the notes or make cash payments upon 
conversions thereof. An event of default under the indenture may lead to an acceleration of our convertible senior notes. Any 
such acceleration could result in our bankruptcy. In a bankruptcy, the holders of our convertible senior notes would have a claim 
to our assets that is senior to the claims of our equity holders. 

In addition, our significant indebtedness, combined with our other financial obligations and contractual commitments, 

could have other important consequences. For example, it could: 

•  make us more vulnerable to adverse changes in general United States and worldwide economic, industry and 

• 
• 
• 

competitive conditions and adverse changes in government regulation; 
limit our flexibility in planning for, or reacting to, changes in our business and our industry; 
place us at a disadvantage compared to our competitors who have less debt; and 
limit our ability to borrow additional amounts for working capital and other general corporate purposes, including to 
fund possible acquisitions of, or investments in, complementary businesses, products, services and technologies. 

Any of these factors could materially and adversely affect our business, financial condition and results of operations. In 

addition, if we incur additional indebtedness, the risks related to our business and our ability to service or repay our 
indebtedness would increase. 

The Credit and Debt Facilities that Provide Capital for Zillow Home Loans Include Covenants and Other Provisions that 
May Restrict Our Operating Activities, and Have a Material Effect on Our Liquidity. They Also Incorporate Variable 
Interest Rates that May Subject Us to Interest Rate Risk, Which Could Cause Our Debt Service Obligations to Increase 
Significantly. 

Zillow Home Loans has entered into warehouse financing agreements, including repurchase agreements, to provide 

capital for the growth and operation of our mortgage origination businesses. The terms of these warehouse financing 
agreements and related financing documents require Zillow Home Loans to comply with a number of customary financial and 
other covenants, such as maintaining certain levels of liquidity, tangible net worth, leverage ratios, net income and adequate 
insurance coverage. These covenants may limit our operational flexibility and may restrict our ability to engage in transactions 
that we believe would otherwise be in the best interests of our shareholders. Additionally, undrawn amounts are generally not 
committed, meaning the applicable lender may not be obligated to advance loan funds in excess of outstanding borrowings. 

35 

 
 
Refer to Note 11 of our Notes to Consolidated Financial Statements in Part II, Item 8 of this Annual Report on Form 10-K for 
additional information on our Zillow Home Loans warehouse financing facilities. Upon the occurrence of any event of default 
under these warehouse financing agreements, the lenders could elect to declare all borrowings outstanding, together with 
accrued and unpaid interest and fees, to be immediately due and payable, even in the absence of a payment default. A default 
under one of our warehouse financing agreements could result in a cross-default under other warehouse financing agreements 
and our lenders could elect to declare outstanding amounts due and payable or terminate their commitments. If we fail to repay 
the amounts due under our warehouse financing agreements, the lenders of such warehouse financing agreements may proceed 
against the collateral granted to secure the credit facilities. The majority of loans originated by Zillow Home Loans are pledged 
as collateral to secure such indebtedness. As a result, a default under applicable debt covenants could have an adverse effect on 
our financial condition or results of operations. 

Certain of our debt agreements are subject to margin calls based on the lender’s opinion of the value of the collateral 

securing such financing. A margin call would require the borrower to repay a portion of the outstanding borrowings. A large, 
unanticipated margin call could have a material effect on our liquidity. 

At December 31, 2023, $93 million of our borrowings under our warehouse financing agreements was at variable rates of 

interest, thereby exposing us to interest rate risk. If interest rates increase, our debt service obligations on the variable rate 
indebtedness would increase even if the amount borrowed remained the same, and our net loss would increase.  

We May Need to Raise Additional Capital to Grow Our Business and We May Not Be Able to Raise Additional Capital on 
Terms Acceptable to Us, or At All. 

Growing and operating our business, including through the development of new and enhanced products and services, may 
require significant cash outlays, liquidity reserves and capital expenditures. If cash on hand, cash generated from operations and 
cash equivalents and investment balances are not sufficient to meet our cash and liquidity needs or fund future growth and 
development, we may need to seek additional capital and we may not be able to raise the necessary cash on terms acceptable to 
us, or at all. Refer to Note 11 of our Notes to Consolidated Financial Statements in Part II, Item 8 of this Annual Report on 
Form 10-K for additional information on our warehouse and loan repurchase facilities. In addition, in February 2021, we 
entered into an Equity Distribution Agreement pursuant to which we may offer and sell from time to time, through certain 
financial institutions, shares of our Class C capital stock having an aggregate gross sales price of up to $1 billion, and in July 
2023, the Board authorized the repurchase of up to an additional $750 million of our Class A common stock, Class C capital 
stock, outstanding convertible senior notes or a combination thereof to bring our total authorized repurchases to $2.5 billion as 
of December 31, 2023. We may decide to raise additional capital or repurchase outstanding stock or debt through these 
arrangements at levels or under terms that prove to be unfavorable or at times and share prices that prove to be disadvantageous 
based on changes in market conditions. Such decisions may negatively impact our financial position and/or future ability to 
raise capital. Financing arrangements we maintain, pursue or assume may require us to grant certain rights, take certain actions, 
or agree to certain restrictions, that could negatively impact our business. If additional capital is not available to us on terms 
acceptable to us or at all, we may need to modify our business plans, which would harm our ability to grow our operations. 

We Rely on Assumptions, Estimates, and Business Data to Calculate our Key Performance Indicators and Other Business 
Metrics, and Real or Perceived Inaccuracies in These Metrics May Harm our Reputation and Negatively Affect our 
Business. 

Certain of our performance metrics are calculated using third party applications or internal company data that have not 

been independently verified. While these numbers are based on what we believe to be reasonable calculations for the applicable 
period of measurement, there are inherent challenges in measuring such information. For example, our measurement of visits 
and unique users may be affected by applications that automatically contact our servers to access our mobile applications and 
websites with no user action involved, and this activity can cause our system to count the user associated with such a device as 
a unique user or as a visit on the day such contact occurs. In addition, our measurement of customer transactions may be 
affected by the availability and quality of public records and other data used to estimate the number of customer transactions 
attributable to our products and services.   

36 

 
 
We regularly review and may adjust our processes for calculating our performance metrics to improve accuracy. Our 

measure of certain metrics may differ from estimates published by third parties or from similarly-titled metrics of our 
competitors due to differences in methodology. If real estate professionals, our real estate partners or investors do not perceive 
our visits, unique users, or customer transactions to be an accurate representation of our user engagement and conversion to 
transactions, or if we discover material inaccuracies in our visits, unique users, or customer transactions, our reputation may be 
harmed, and real estate professionals and advertisers may be less willing to allocate their resources to our products and services, 
which could negatively affect our business and operating results. 

We Expect Our Results of Operations to Fluctuate on a Quarterly and Annual Basis. 

Our revenue and results of operations could vary significantly from period to period and may fail to match expectations 
as a result of a variety of factors, some of which are outside our control. The other risk factors discussed in this “Risk Factors” 
section may contribute to the variability of our quarterly and annual results. In addition, our results may fluctuate as a result of 
seasonal variances of home sales, which historically peak in the spring and summer seasons, fluctuations in the quantity of 
homes available, our remnant advertising, and the size and seasonal variability of our real estate partners’ marketing budgets. 
The seasonal variance and cyclical nature of home sales may contribute to the variability of our revenue and results of 
operations for our Mortgages business, in particular, which seasonality may be masked by business growth. As a result of the 
potential variations in our revenue and results of operations, period-to-period comparisons may not be meaningful and the 
results of any one period should not be relied on as an indication of future performance. In addition, our results of operations 
may not meet the expectations of investors or public market analysts who follow us, which may adversely affect our stock 
price. 

We Could Be Subject to Additional Tax Liabilities. 

We are subject to income taxes in the United States (federal and state) and certain foreign jurisdictions. Tax laws, 
regulations, and administrative practices in various jurisdictions may be subject to significant change, with or without notice, 
due to economic, political, and other conditions. New tax laws, regulations and administrative practices could be enacted or 
adopted at any time, and existing tax laws, regulations and administrative practices could be interpreted, modified or applied 
adversely to us, possibly with retroactive effect. These changes could require us to pay additional taxes, penalties, interest and 
other related costs, and also could increase our compliance, operating and other costs.  

Significant judgment is required in evaluating and estimating the taxes imposed under such tax laws. Our effective tax 

rates could be affected by numerous factors, such as entry into new businesses and geographies, changes to our existing 
business and operations, acquisitions and investments and how they are financed, changes in our stock price, changes in our 
deferred tax assets and liabilities and their valuation, and changes in the relevant tax, accounting, and other laws, regulations, 
administrative practices, principles, and interpretations. We are required to take positions regarding the interpretation of 
complex statutory and regulatory tax rules and on valuation matters that are subject to uncertainty, and the Internal Revenue 
Service or other tax authorities may challenge the positions we take. 

Our Ability to Use Our Net Operating Loss Carryforwards and Certain Other Tax Attributes May Be Limited. 

We have incurred losses during our history. To the extent that we continue to generate losses, unused losses will carry 

forward to offset future taxable income, if any, until such unused losses expire, if at all. Under the Tax Act, as modified by the 
Coronavirus Aid, Relief, and Economic Security Act, United States federal net operating loss carryforwards generated in 
taxable years beginning after December 31, 2017, may be carried forward indefinitely, but the deductibility of such net 
operating loss carryforwards in taxable years beginning after December 31, 2020 is limited to 80% of taxable income. 

In addition, under Sections 382 and 383 of the Internal Revenue Code of 1986, as amended (the “Code”), if a corporation 
undergoes an “ownership change”, the corporation’s ability to use its pre-change net operating loss carryforwards and other pre-
change tax attributes, such as research and development credits, to offset its post-change taxable income or income tax liability 
may be limited. An “ownership change” occurs for these purposes if one or more shareholders (including certain groups of 
shareholders) that each owns at least 5% of the corporation’s stock by value increase their aggregate ownership by more than 50 
percentage points over their lowest ownership percentages within a rolling three-year period. Similar rules may apply under 

37 

 
 
state tax laws. We have undergone ownership changes in the past, and we may experience ownership changes in the future 
because of shifts in our stock ownership, many of which are outside of our control. As a result, if we achieve profitability, our 
ability to use our net operating loss carryforwards and other tax attributes to offset future United States federal taxable income 
or income tax liabilities may be, or may become, subject to limitations, which could result in increased future tax liability to us. 

Risks Related to Ownership of Our Common and Capital Stock and Debt Instruments 

Our Class A Common Stock and Class C Capital Stock Prices May Be Volatile, and the Value of an Investment in Our Class 
A Common Stock and Class C Capital Stock May Decline. 

An active, liquid and orderly market for our Class A common stock and Class C capital stock may not be sustained, 
which could depress the trading price of our Class A common stock and Class C capital stock. The trading price of our Class A 
common stock and Class C capital stock has at times experienced price volatility and may continue to be volatile. For example, 
during the last three fiscal years ending December 31, 2023, the closing price of our Class A common stock has ranged from 
$27.02 per share to $203.79 per share. During the same time period, the closing price of our Class C capital stock has ranged 
from $26.97 per share to $199.90 per share. The market price of our Class A common stock and Class C capital stock could be 
subject to wide fluctuations in response to many of the risk factors discussed in this Annual Report on Form 10-K and others 
beyond our control, including: 

• 
• 
• 
• 
• 

• 
• 
• 
• 
• 

• 
• 
• 
• 
• 
• 

actual or anticipated fluctuations in our financial condition and results of operations; 
changes in projected operational and financial results; 
addition or loss of significant customers; 
actual or anticipated changes in our growth rate relative to that of our competitors; 
announcements by us or our competitors of significant acquisitions, strategic partnerships, joint ventures or capital-
raising activities or commitments; 
announcements of technological innovations or new offerings by us or our competitors; 
additions or departures of key personnel; 
changes in laws or regulations applicable to our services; 
fluctuations in the valuation of companies perceived by investors to be comparable to us; 
the inclusion, exclusion, or deletion of our Class A common stock and Class C capital stock from any trading indices, 
such as the S&P 500 Index; 
issuance of new or updated research or reports by securities analysts; 
sales of our Class A common stock and Class C capital stock by us or our shareholders; 
repurchases of our Class A common stock and Class C capital stock by us or our shareholders; 
issuances of our Class C capital stock upon conversion of our 2024 Notes, 2025 Notes or 2026 Notes; 
stock price and volume fluctuations attributable to inconsistent trading volume levels of our shares; and 
general economic and market conditions. 

Furthermore, the stock markets in recent years have experienced extreme price and volume fluctuations that have affected 

and continue to affect the market prices of the equity securities of many companies. These fluctuations often have been 
unrelated or disproportionate to the operating performance of those companies. These broad market and industry fluctuations, 
as well as general economic, political and market conditions such as recessions, changes to federal monetary policy, interest 
rates or international currency fluctuations, may negatively impact the market price of our Class A common stock and Class C 
capital stock. In the past, companies that have experienced volatility in the market price of their stock have been subject to 
securities class action litigation. We have in the past been and are currently the target of this type of litigation, and we may 
continue to be the target of this type of litigation in the future. Past, current, and future securities litigation against us could 
result in substantial costs and divert management’s attention from other business concerns, which could harm our business, 
results of operations or financial condition. 

38 

 
 
 
 
The Structure of Our Capital Stock as Contained in Our Charter Documents Has the Effect of Concentrating Voting 
Control With Our Founders, and Limits Your Ability to Influence Corporate Matters. 

Since Zillow Group’s inception, our capital structure has included authorized Class A common stock and authorized Class 
B common stock. Our Class A common stock entitles its holder to one vote per share, and our Class B common stock entitles its 
holder to 10 votes per share. All shares of Class B common stock have been and are held or controlled by our founders, Richard 
Barton and Lloyd Frink. As of December 31, 2023, Mr. Barton’s holdings and Mr. Frink’s holdings represented approximately 
32.2% and 20.9%, respectively, of the voting power of our outstanding capital stock. 

For the foreseeable future, Mr. Barton and Mr. Frink will therefore have significant control over our management and 

affairs and will be able to control most matters requiring shareholder approval, including the election or removal (with or 
without cause) of directors and the approval of any significant corporate transaction, such as a merger or other sale of us or our 
assets. In addition, because our Class C capital stock carries no voting rights (except as required by applicable law or as 
expressly provided in our amended and restated articles of incorporation), the issuance of Class C capital stock (instead of Class 
A common stock) could prolong the duration of Mr. Barton’s and Mr. Frink’s relative ownership of our voting power. This 
concentrated control could delay, defer or prevent a change of control, merger, consolidation, takeover, or other business 
combination involving us that you, as a shareholder, may otherwise support. This concentrated control could also discourage a 
potential investor from acquiring our Class A common stock or Class C capital stock due to the limited voting power of such 
stock relative to the Class B common stock and might harm the market price of our Class A common stock and Class C capital 
stock. 

Future Sales of Our Stock in the Public Market Could Cause Our Stock Price to Decline. 

We cannot predict the effect, if any, that market sales of shares or the availability of shares for sale will have on the 

prevailing trading price of our Class A common stock and Class C capital stock from time to time. There is currently no 
contractual restriction on our ability to issue additional shares, and all of our outstanding shares are generally freely tradable, 
except for shares held by our “affiliates” as defined in Rule 144 under the Securities Act of 1933, as amended, which may be 
sold in compliance with the volume restrictions of Rule 144. Sales of a substantial number of shares of our Class A common 
stock and Class C capital stock could cause our stock price to decline. In addition, we may in the future issue shares of Class C 
capital stock for financings, acquisitions, equity incentives, including under our Equity Distribution Agreement or to settle our 
outstanding convertible notes. If we issue shares of Class C capital stock in the future, such issuances would have a dilutive 
effect on the economic interest of our Class A common stock. 

We Cannot Guarantee that Our Securities Repurchase Program Will Enhance Shareholder Value, and Repurchases Could 
Affect the Price of Our Class A Common Stock, Class C Capital Stock and Convertible Senior Notes. 

Prior to July 31, 2023, our board of directors authorized the repurchase of up to $1.8 billion of our Class A common 

stock, Class C capital stock, outstanding convertible senior notes or a combination thereof. On July 31, 2023, our board 
authorized an additional $750 million in such repurchases, increasing the authorization under the repurchase program to 
$2.5 billion. As of December 31, 2023, $770 million remained available under the securities repurchase program (collectively, 
the “Repurchase Authorizations”). 

There is no expiration date for the Repurchase Authorizations. The timing and actual number of shares or notes 
repurchased, if any, depend on a variety of factors including the timing of open trading windows, price, corporate and 
regulatory requirements, and other market conditions. The program may be suspended or discontinued at any time without prior 
notice. Repurchases pursuant to the Repurchase Authorizations could affect the price of our Class A common stock, Class C 
capital stock and outstanding convertible notes and increase volatility in such securities. 

39 

 
 
 
 
If Securities or Industry Analysts or Other Third Parties Do Not Publish Research or Publish Inaccurate or Unfavorable 
Research About Our Business, Our Class A Common Stock and Class C Capital Stock Price and Trading Volume Could 
Decline. 

The trading market for our Class A common stock and Class C capital stock depends in part on the research and reports 
that securities or industry analysts or other third parties publish about our company. If few or no securities or industry analysts 
or other third parties cover our company, the market price of our publicly-traded stock could be negatively impacted. If 
securities or industry analysts or other third parties cover us and if one or more of such analysts downgrade our stock or publish 
inaccurate or unfavorable research about our business, our stock price would likely decline. If one or more of the analysts 
covering us fail to publish reports on us regularly, demand for our stock could decline, which could cause our stock price and 
trading volume to decline. 

If We Issue Additional Equity Securities or Convertible Debt to Raise Capital or Elect to Settle Conversions of Our 
Convertible Senior Notes in Stock, It May Have a Dilutive Effect on Shareholders’ Investment. 

If we raise additional capital through further issuances of equity or convertible debt securities or elect to settle 

conversions of our convertible senior notes in shares of our Class C capital stock, our existing shareholders could suffer 
significant dilution in their percentage ownership of us. Moreover, any new equity securities we issue could have rights, 
preferences and privileges senior to those of holders of our common stock. 

The Capped Call Transactions May Affect the Value of Our 2024 Notes, 2026 Notes and Our Class C Capital Stock. 

In connection with the pricing of each of the 2024 Notes and 2026 Notes, we entered into capped call transactions with 

certain financial institutions (the “option counterparties”). The capped call transactions are expected generally to reduce 
potential dilution in connection with the conversion of the 2024 Notes or 2026 Notes and/or offset any cash payments we are 
required to make in excess of the principal amount of converted notes, as the case may be. In connection with our Convertible 
Senior Notes due in 2023 (“2023 Notes”), the balance of which we redeemed in mid-2021, we exercised our right to keep the 
associated capped call confirmations open through the expiration of the 2023 Notes, which caused short term dilution. We may 
pursue similar options with the capped call confirmations associated with each of the 2024 Notes and 2026 Notes in the future. 

The option counterparties or their respective affiliates may modify their hedge positions by entering into or unwinding 

various derivative transactions with respect to our Class C capital stock and/or purchasing or selling our Class C capital stock or 
other securities of ours in secondary market transactions prior to the maturity of each of the 2024 Notes and 2026 Notes (and 
are likely to do so during any observation period related to a conversion of 2024 Notes or 2026 Notes or in connection with any 
repurchase or redemption of 2024 Notes or 2026 Notes by us). This activity could cause or avoid an increase or a decrease in 
the market price of our Class C capital stock, the 2024 Notes or the 2026 Notes. 

Anti-Takeover Provisions in Our Charter Documents and Under Washington Law Could Make an Acquisition of Us More 
Difficult, Limit Attempts by Shareholders to Replace or Remove Our Management and Affect the Market Price of Our Stock. 

Provisions in our articles of incorporation and bylaws, as amended and restated, may have the effect of delaying or 
preventing a change of control or changes in our management. Our amended and restated articles of incorporation or amended 
and restated bylaws include provisions, some of which will become effective only after the date, which we refer to as the 
threshold date, on which the Class B common stock controlled by our founders represents less than 7% of the aggregate number 
of shares of our outstanding Class A common stock and Class B common stock, that: 

• 

• 

• 

set forth the structure of our capital stock, which concentrates voting control of matters submitted to a vote of our 
shareholders with the holders of our Class B common stock, which is held or controlled by our founders; 
authorize our board of directors to issue, without further action by our shareholders, up to 30,000,000 shares of 
undesignated preferred stock, subject, prior to the threshold date, to the approval rights of the holders of our Class B 
common stock; 
establish that our board of directors will be divided into three classes, Class I, Class II and Class III, with each class 
serving three-year staggered terms; 

40 

 
 
• 
• 
• 

• 
• 

• 

• 

• 

prohibit cumulative voting in the election of directors; 
provide that, after the threshold date, our directors may be removed only for cause; 
provide that, after the threshold date, vacancies on our board of directors may be filled only by the affirmative vote of 
a majority of directors then in office or by the sole remaining director; 
provide that only our board of directors may change the board’s size; 
specify that special meetings of our shareholders can be called only by the chair of our board of directors, our board of 
directors, our chief executive officer, our president or, prior to the threshold date, holders of at least 25% of all the 
votes entitled to be cast on any issue proposed to be considered at any such special meeting; 
establish an advance notice procedure for shareholder proposals to be brought before a meeting of shareholders, 
including proposed nominations of persons for election to our board of directors; 
require the approval of our board of directors or the holders of at least two-thirds of all the votes entitled to be cast by 
shareholders generally in the election of directors, voting together as a single group, to amend or repeal our bylaws; 
and 
require the approval of not less than two-thirds of all the votes entitled to be cast on a proposed amendment, voting 
together as a single group, to amend certain provisions of our articles of incorporation. 

Prior to the threshold date, our directors can be removed with or without cause by holders of our Class A common stock 

and Class B common stock, voting together as a single group, and vacancies on the board of directors may be filled by such 
shareholders, voting together as a single group. Given the structure of our capital stock, our founders, Richard Barton and Lloyd 
Frink, who hold or control our Class B common stock, will have the ability for the foreseeable future to control these 
shareholder actions. See the risk factor above titled “The Structure of Our Capital Stock as Contained in Our Charter 
Documents Has the Effect of Concentrating Voting Control With our Founders, and Limits Your Ability to Influence Corporate 
Matters.” 

The provisions described above, after the threshold date, may frustrate or prevent any attempts by our shareholders to 
replace or remove our current management by making it more difficult for shareholders to replace members of our board of 
directors, which board is responsible for appointing our management. In addition, because we are incorporated in the State of 
Washington, we are governed by the provisions of Chapter 23B.19 of the Washington Business Corporation Act, which 
prohibits certain business combinations between us and certain significant shareholders unless specified conditions are met. 
These provisions may also have the effect of delaying or preventing a change of control of our company, even if this change of 
control would benefit our shareholders. 

Item 1B. Unresolved Staff Comments. 

Not applicable. 

Item 1C. Cybersecurity. 

Cyber-attacks, malicious internet-based activity, online and offline fraud, administrative or technical failures and other 

cybersecurity threats present risks to the confidentiality, integrity and availability of our information systems, including those of 
the third parties upon which we rely, and our data residing in those systems. We take seriously our responsibility to protect 
sensitive consumer, customer and employee information. 

Given the data-driven nature of our business and the prevalent use of technology in operating our business, we face 

cybersecurity risks that could materially affect our business strategy, results of operations and financial condition. For further 
details on the exposures related to these risks, see the section titled “Risk Factors” within this Annual Report on Form 10-K. 

Risk Management, Strategy and Management Oversight 

We have an enterprise risk management function at Zillow Group responsible for the oversight and assessment of 
ongoing and emerging risks to our business operations and the integrity of our data, including the impact of cybersecurity risks. 
Our enterprise risk management team maintains a steering committee that oversees and opines on our processes to identify, 
prioritize and assess key risks, including risks related to cybersecurity. The steering committee is composed of senior, cross-

41 

 
 
functional business leaders with visibility into our key risks. Such members have expertise in the areas of risk management, 
business strategy, information technology, cybersecurity, legal and compliance, finance, communications, and business 
products, among others. In partnership with risk owners, this steering committee monitors risk exposures and verifies that 
efficient and effective risk-management strategies or acceptance and notification criteria are in place. The steering committee 
meets at least quarterly and its activities are overseen by the Audit Committee of our Board of Directors (“Board”). 

We also maintain an information security function that oversees the protection of our information assets through a 
program informed by standards promoted by the National Institute of Standards and Technology cybersecurity framework and 
the Cyber Risk Institute’s Cyber Profile. These frameworks guide our information security function in designing programs to 
assess cybersecurity risks and prevent cybersecurity incidents. The information security team is led by our Chief Information 
Security Officer (“CISO”) who is responsible for leading enterprise-wide cybersecurity strategy, including assessing and 
managing risks from cybersecurity threats, and implementing technical security controls by maintaining policies, standards and 
processes. With more than 20 years of experience in the field of cybersecurity, our CISO has had extensive involvement with 
the information security function and the maintenance of a robust cybersecurity program. Our CISO has held data privacy and 
information security roles with increasing responsibility in the financial services, technology and casino industries and is a 
certified information systems security professional.  

The information security team maintains incident response policies and procedures designed to help protect the integrity, 

availability and confidentiality of information and help prevent loss of service. Cybersecurity events and incidents may be 
reported or detected through a variety of means, including emails to centralized information security addresses, our online 
information technology ticketing system, automatic alerts and incident detection systems, direct discovery by our information 
security team, or reports from a third party. Additionally, our incident response policies and procedures specify the process for 
initial investigation and containment procedures, remediation tactics, retention of documentation and internal and external 
communications. Our incident response policies and procedures also specify processes for analyzing the severity of an 
identified incident, which serve to dictate the escalation procedures to notify varying levels of our risk management team. In 
response to cybersecurity incidents, we may involve external advisors to assist with remediation efforts and communications 
and we may seek to mitigate associated liabilities through our insurance coverage. Such third parties may include external legal 
counsel, forensic investigators and public relation firms, among others. These vendors serve to support our existing processes 
and procedures and operate as an extension of our enterprise risk management and information security functions. 

Our internal audit team conducts security controls testing and provides independent validation that such controls are 
operating effectively on systems in scope for various regulatory and compliance requirements. Our regulatory compliance team 
uses third-party external auditors to perform independent testing against all systems in scope for our regulatory and customer-
driven compliance obligations. The audit cadence aligns with regulatory and customer-driven needs. The scope of our audits 
includes all systems that store, transmit or process data. We also perform periodic third-party risk assessments, vulnerability 
testing, system and cloud security assessments against our information technology systems. 

We engage a variety of third-party service providers to process and store data, including certain customer information, 

some of which may include personally identifiable information. We also depend on third-party service providers to host many 
of the systems and infrastructure used to provide our products and services. A limited number of third-party services support 
essential functions of our business, including the use of cloud-based technology. We have a third-party service provider 
management program to manage cybersecurity risks associated with our use of these third-party service providers. The program 
includes the use of security questionnaires, review of statements of work and related information security addenda, procuring 
results of audits and compliance reviews and obtaining overviews of network infrastructure, among others. Based upon the 
extent and type of services utilized, reviews of certain third-party engagements are coordinated through members of the 
following management teams: procurement, legal, compliance, enterprise risk management and information security risk 
management, among others, as applicable. Depending on the nature of the services provided, the sensitivity of the data at issue 
and the identity of the third-party, our third-party service provider management process may involve different levels of 
assessment designed to help identify cybersecurity risks associated with a provider and impose contractual obligations related 
to cybersecurity on the provider. 

42 

 
 
 
 
Governance 

Our Board considers risk assessment and development of risk mitigation strategies to be a responsibility of the entire 

Board in consultation with the appropriate Board committees. The Board regularly engages in risk oversight on a broad range 
of matters, including challenges associated with strategic acquisitions, cybersecurity, regulatory and other legal and compliance 
matters. For more focused risk oversight, our Board committees are tasked with specific risk management roles. 

The Audit Committee oversees major enterprise risks and the steps management has taken to monitor and control such 

exposure, including risks to our information technology infrastructure and security. Members of our legal, compliance, 
enterprise risk management and information security management teams provide information and updates on any significant 
issues related to these topics at the periodic Audit Committee meetings, which are typically held at least quarterly. The Audit 
Committee is responsible for ensuring independent examination of management’s programs to identify, assess, respond to and 
monitor risks, which include those performed by internal audit and third party consultants, among others. 

Audit Committee member education is provided throughout the year through presentations to and discussions with the 
Audit Committee led by members of management, third-party consultants, our independent registered public accounting firm 
and legal counsel, on topics including information security, among others. Members of our Audit Committee have expertise in 
the technology industry as well as corporate risk management strategies.

Market Information and Holders 

Our Class A common stock has traded on The Nasdaq Global Select Market under the symbol “ZG” since August 17, 

2015 and under the symbol “Z” from July 20, 2011 through August 14, 2015. 

Our Class B common stock is not listed and there is no established public trading market. 

Our Class C capital stock has traded on The Nasdaq Global Select Market under the symbol “Z” since August 17, 2015. 

Prior to that time, there was no public market for our Class C capital stock. 

Holders of Record 

As of February 7, 2024, there were 291, three, and 154 holders of record of our Class A common stock, our Class B 

common stock, and our Class C capital stock, respectively. 

Dividends 

We have never declared or paid a cash dividend on our common or capital stock and we intend to retain all available 

funds and any future earnings to fund the development and growth of our business. We therefore do not anticipate paying any 
cash dividends on our common or capital stock in the foreseeable future. Any future determinations to pay dividends on our 
common or capital stock would depend on our results of operations, our financial condition and liquidity requirements, 
restrictions that may be imposed by applicable law or our contracts and any other factors that our board of directors may 
consider relevant.

(1) On December 2, 2021, the Board of Directors authorized a stock repurchase program granting the authority to repurchase
up to $750 million of our Class A common stock, Class C capital stock or a combination thereof. On May 4, 2022, the Board
of Directors authorized the repurchase of up to an additional $1 billion of our Class A common stock, Class C capital stock or
a combination thereof. On November 1, 2022, the Board of Directors further expanded these authorizations to allow for the
repurchase of a portion of our outstanding convertible senior notes. On July 31, 2023, the Board authorized the repurchase of
up to an additional $750 million of Class A common stock, Class C capital stock, outstanding convertible senior notes or a
combination thereof (together with the previous authorizations, “Repurchase Authorizations”). The Repurchase Authorizations
do not have an expiration date. During the three months ended December 31, 2023, we repurchased $58 million aggregate
principal amount of convertible senior notes for $56 million in cash, plus accrued interest, which reduced the remaining dollar
value available under the Repurchase Authorizations.

Item 7. 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 

audited consolidated financial statements and the related notes included elsewhere in this Annual Report on Form 10-K. The 
following discussion focuses on 2023 and 2022 financial condition and results of operations and year-to-year comparisons 
between 2023 and 2022. Similar discussion of our 2021 financial condition and results and year-to-year comparisons between 
2022 and 2021 can be found in “Management’s Discussion and Analysis of Financial Condition and Results of Operations” in 
Part II, Item 7 of the Company’s Annual Report on Form 10-K for the year ended December 31, 2022. 

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 Annual Report on Form 10-K, particularly in the sections titled “Note Regarding Forward Looking Statements” and “Risk 
Factors”. 

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. (cid:3)

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. 

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 have a negative impact on 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 
declined 17% during the year ended December 31, 2023 as compared to the year ended December 31, 2022. Despite the 
industry headwinds and total transaction value declines, 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 year ended December 31, 2023 as 
compared to the year ended December 31, 2022, 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. 

Acquisitions 

 On December 8, 2023, we acquired Enchant, LLC, d/b/a Follow Up Boss (“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. On September 
11, 2023, we acquired substantially all of the assets and liabilities of Spruce Holdings, Inc. and certain affiliated entities 
(collectively referred to as “Spruce”), a tech-enabled title and escrow platform, in exchange for total consideration of 
$19 million, net of cash acquired. On July 31, 2023, we acquired Aryeo, Inc. (“Aryeo”), a software company that serves real 
estate photographers, in exchange for total consideration of $35 million, net of cash acquired. For additional information on 
acquisitions, see Note 7 in our Notes to the Consolidated Financial Statements in Part II, Item 8 of this Annual Report on Form 
10-K.

Discontinued Operations 

In the fourth quarter of 2021, the Board of Directors (the “Board”) of Zillow Group made the determination to wind 

47 

down the operations of Zillow Offers, our iBuying business which purchased and sold homes directly in certain markets across 
the United States. The wind down was completed in the third quarter of 2022 and resulted in approximately a 25% reduction of 
Zillow Group’s workforce. The financial results of Zillow Offers have been presented in the accompanying consolidated 
financial statements as discontinued operations and, therefore, are excluded from the following discussion of the results of our 
continuing operations. Given the wind down of Zillow Offers and corresponding shift in our strategic plans, financial 
performance for prior and current periods may not be indicative of future performance. For additional information regarding 
discontinued operations, see Note 3 in our Notes to the Consolidated Financial Statements in Part II, Item 8 of this Annual 
Report on Form 10-K. 

August 2022 Equity Award Actions 

On August 3, 2022, upon the recommendation of the Compensation Committee of the Board, the Board approved 
adjustments to the exercise price of certain outstanding vested and unvested option awards for eligible employees. The exercise 
price of eligible option awards was reduced to $38.78, which was the closing market price of our Class C capital stock on 
August 8, 2022. No other changes were made to the terms and conditions of the eligible option awards. In addition, the Board 
approved a supplemental grant of restricted stock units to eligible employees that was granted on August 8, 2022 and vests 
quarterly over a two-year period beginning in August 2022. The repricing of eligible option awards and the issuance of 
supplemental restricted stock units (collectively the “August 2022 Equity Award Actions”) has and is expected to continue to 
result in incremental share-based compensation expense over the remaining requisite service period, which is largely through 
the third quarter of 2024. For additional information regarding the August 2022 Equity Award Actions, see Note 14 in our Notes 
to the Consolidated Financial Statements in Part II, Item 8 of this Annual Report on Form 10-K. 

Change in Reportable Segments 

Beginning in 2023, our chief executive officer, who acts as the chief operating decision maker, began to manage our 
business, make operating decisions, and evaluate operating performance on the basis of the company as a whole, instead of on a 
segment basis as he did prior to 2023. Accordingly, this change led to revisions in the nature and substance of information 
regularly provided to and used by the chief operating decision maker and served to align our reported results with our ongoing 
growth strategy and our intent to provide integrated customer solutions for all tasks and services related to facilitating real 
estate transactions. As a result, beginning in the first quarter of 2023, we began to report our financial results as a single 
reportable segment. 

Revenue Overview 

Our revenue is classified into four categories: Residential, Rentals, Mortgages and Other. Certain prior period amounts 

have been revised to reflect these changes. 

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. 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. Connections are delivered when customer contact 
information is provided to Premier Agent partners. Connections are provided as part of our suite of advertising services for 
Premier Agent partners; we do not charge a separate fee for these customer leads. 

Our pay for performance pricing model is called “Flex” and is available in certain markets to select partners. With the 

Flex model, Premier Agent partners are provided with validated leads at no initial cost and pay a performance advertising fee 

48 

 
 
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. StreetEasy for-sale revenue includes advertising services sold to real estate 
professionals serving the New York City for sale market primarily on a cost per property or performance fee 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 
include call center specialists who provide scheduling support to customers. Appointment Center revenue is primarily billed in 
advance on a monthly basis. ShowingTime+ revenue also includes our dotloop real estate transaction management software-as-
a-service solution. Dotloop is a monthly subscription service allowing real estate partners to efficiently manage their 
transactions. 

Rentals. Rentals revenue includes advertising and a suite of tools sold to property managers, landlords and other rental 

professionals 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. Display revenue consists of graphical 
mobile and web advertising sold on a cost per thousand impressions or cost per click basis to advertisers promoting their brands 
on our mobile applications and websites.  

For additional information regarding our revenue recognition policies, see Note 2 of our Notes to Consolidated Financial 

Statements in Part II, Item 8 of this Annual Report on Form 10-K. 

Financial Overview 

For the years ended December 31, 2023 and 2022, we generated revenue of $1.9 billion and $2.0 billion, respectively, 

representing a year-over-year decrease of 1%. The decrease in total revenue was primarily attributable to the following: 

•  Residential revenue decreased by $70 million, or 5%, for the year ended December 31, 2023 compared to the year 

ended December 31, 2022. The decrease in Residential revenue was primarily driven by a 5% decrease in the number 
of visits for the year ended December 31, 2023 compared to the year ended December 31, 2022. This decrease was 
primarily due to macro housing market factors including low housing inventory, fewer new for-sale listings, increases 
and volatility in mortgage interest rates, as well as home price fluctuations. 

•  Mortgages revenue decreased by $23 million to $96 million for the year ended December 31, 2023 compared to $119 
million for the year ended December 31, 2022, primarily driven by a $28 million decrease in revenue from Custom 
Quote and Connect advertising services due to a 32% decrease in leads generated from marketing products sold to 
mortgage professionals. This decrease in leads was primarily driven by a decrease in demand for mortgages 
attributable to the higher interest rate environment as compared to the prior year period, as well as a shift in strategic 
priority as we focus on organic growth of our mortgage origination business.  

•  The decreases noted above were partially offset by an $83 million increase to Rentals revenue to $357 million for the 
year ended December 31, 2023 compared to $274 million for the year ended December 31, 2022. The increase in 
Rentals revenue was primarily due to a 21% increase in quarterly revenue per average monthly rentals unique visitor 
to $3.19 for the year ended December 31, 2023 as compared to $2.63 for the year ended December 31, 2022, 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. The increase in Rentals revenue was also driven by 

49 

 
 
growth in average monthly rentals unique visitors which increased 8% to 28 million during the year ended December 
31, 2023 from 26 million during the year ended December 31, 2022, primarily driven by the increase in active rental 
listings.  

For the years ended December 31, 2023 and 2022, we generated total gross profit of $1.5 billion and $1.6 billion, 

respectively, representing a year-over-year decrease of 4%, due to the combined factors discussed above. 

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 are more sought-
after by our Premier Agent partners. 

We define a visit as a group of interactions by users with the 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. 

Zillow and StreetEasy measure visits with Google Analytics, and Trulia measures visits with Adobe Analytics. Visits to 

Trulia end after thirty minutes of user inactivity. Visits to Zillow and StreetEasy end 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 arrives via one 
campaign or source (for example, via a search engine or referring link on a third-party website), leaves the mobile application 
or website, and then returns via another campaign or source. 

The following table presents the number of visits to our mobile applications and websites for the periods presented (in 

millions, except percentages):

 (5) % 

During the year ended December 31, 2023, visits to our mobile applications and websites decreased by 5% compared to 

the year ended December 31, 2022. This decrease was primarily driven by macro housing market factors including low housing 
inventory, fewer new for-sale listings, increases and volatility in mortgage interest rates as well as home price fluctuations. 

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 

50 

 
 
 
 
 
 
 
 
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. Zillow, 
StreetEasy and HotPads measure unique users with Google Analytics, and Trulia measures unique users with Adobe Analytics. 

Due to third-party technological limitations, user software settings, or user behavior, Google Analytics may assign a 
unique cookie to different instances of access by the same individual to our mobile applications and websites. In such instances, 
Google Analytics would count different instances of access by the same individual as separate unique users. Accordingly, 
reliance on the number of unique users counted by Google Analytics may overstate the actual number of unique users who 
access our mobile applications and websites during the period.  

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

percentages):

 (3) % 

During the year ended December 31, 2023, average monthly unique users to our mobile applications and websites 

decreased by 3% compared to the year ended December 31, 2022. This decrease was primarily driven by macro housing market 
factors including low housing inventory, fewer new for-sale listings, increases and volatility in mortgage interest rates as well as 
home price fluctuations. 

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):

Purchase loan origination volume increased during the year ended December 31, 2023 due to continued growth in Zillow 
Home Loans purchase loan originations. This increase was offset by a decrease in refinance loan origination volume which was 
driven by higher interest rates which decreased demand for refinance mortgages. 

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.

Total revenue decreased $13 million, or 1%, to $1.9 billion: 

•  Residential revenue decreased $70 million, or 5%. This decrease was driven by a 5% decrease in the number of 
visits for the year ended December 31, 2023 compared to the year ended December 31, 2022. This decrease was 
primarily due to macro housing market factors including low housing inventory, fewer new for-sale listings, 
increases and volatility in mortgage interest rates as well as home price fluctuations. These factors also resulted in a 
6% decrease in Premier Agent revenue during the year ended December 31, 2023 compared to the year ended 
December 31, 2022. We expect Residential revenue to increase in absolute dollars during the three months ending 
March 31, 2024, primarily due to the stabilization of macro housing market factors described above as well as 
incremental revenue attributable to the Follow Up Boss acquisition, product expansion and seasonality. 

•  Mortgages revenue decreased $23 million, or 19%. This decrease was driven by a $28 million decrease in our 

Custom Quote and Connect advertising services revenue, partially offset by an $8 million increase in mortgage 
originations revenue. The decrease in our Custom Quote and Connect advertising revenue 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 decrease in demand for mortgages attributable to the higher interest rate environment as 
compared to the prior year period, as well as a shift in strategic priority as we focus on organic growth of our 
mortgage origination business. The decrease in Custom Quote and Connect advertising services revenue was 
partially offset by an $8 million increase in mortgage originations revenue, primarily due to a 22% increase in gain 
on sale margin driven by fewer interest rate increases in 2023 as compared to 2022, resulting in higher profitability 
on the sale of mortgage loans in the secondary market. 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 interest 
rate lock commitments 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.   

•  Rentals revenue increased $83 million, or 30%. The increase in Rentals revenue was primarily due to a 21% 

increase in quarterly revenue per average monthly rentals unique visitor to $3.19 for the year ended December 31, 
2023 as compared to $2.63 for the year ended December 31, 2022, 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. 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. The increase in Rentals revenue was also driven by growth in average 
monthly rentals unique visitors which increased 8% to 28 million during the year ended December 31, 2023 from 
26 million during the year ended December 31, 2022, primarily driven by the increase in active rental listings. 
Average monthly rentals unique visitors are measured with Comscore data, which includes average monthly unique

To provide investors with additional information regarding our financial results, we have disclosed Adjusted EBITDA, a 
non-GAAP financial measure, within this Annual Report on Form 10-K. We have provided a reconciliation below of Adjusted 
EBITDA to net loss, the most directly comparable U.S. generally accepted accounting principles (“GAAP”) financial measure. 

We have included Adjusted EBITDA in this Annual Report on Form 10-K 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 reflect the results of discontinued operations; 

•  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 and restructuring costs; 

•  Adjusted EBITDA does not reflect acquisition-related costs; 

•  Adjusted EBITDA does not reflect the gain on extinguishment of debt; 

•  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. 

The following table presents a reconciliation of Adjusted EBITDA to the most directly comparable GAAP financial 

measure, which is net loss for each of the periods presented (in millions):

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. 

Cost of revenue increased $54 million, or 15%, primarily driven by increases of $38 million in depreciation and 
amortization expense due to an increase in website development costs, $10 million in ad serving costs, $7 million in software 
and hardware costs and $7 million in mortgage loan processing costs due to increased purchase loan origination volume. These 
increases were partially offset by a $7 million decrease in lead acquisition costs as we shift our strategic priorities to focus on 
organic growth of our mortgage origination business.  

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. 

Gross profit decreased by $67 million, or 4%, primarily due to an increase in cost of revenue, discussed above. Total 

gross margin decreased from 81% to 78%.  

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. 

Sales and marketing expenses decreased $6 million, or 1%, due to decreases of $7 million in marketing and advertising 
costs and $4 million in third-party professional service fees, both driven by active cost management, a $2 million decrease in 
depreciation and amortization expense and a $2 million decrease in trade shows and events. These decreases were partially 
offset by a $7 million increase in travel expenses and a $3 million increase in software and hardware costs. 

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 software maintenance costs and depreciation expense. 

Technology and development expenses increased $62 million, or 12%, primarily due to increases of $54 million in 
headcount-related expenses, including share-based compensation expense, primarily driven by the August 2022 Equity Award 
Actions, $6 million in travel expenses and $5 million in software and hardware costs. These increases were partially offset by a 
decrease of $3 million in third-party professional service fees. 

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. 

General and administrative expenses increased $55 million, or 11%, due to a $35 million increase in headcount-related 

55 

 
 
expenses, including share-based compensation expense, primarily driven by an $18 million increase in share-based 
compensation expense associated with the departures of certain personnel, as well as the impact of the August 2022 Equity 
Award Actions. The increase in general and administrative expenses was also driven by a $13 million increase in rent expense, 
primarily due to $14 million of additional rent expense recognized in connection with the partial termination of our Seattle 
lease. For additional information on leases, see Note 10 of our Notes to Consolidated Financial Statements in Part II, Item 8 of 
this Annual Report on Form 10-K. The increase in general and administrative expenses was also driven by increases of $4 
million in third-party professional service fees, $3 million in software and hardware costs and $2 million in travel expenses. We 
expect general and administrative expenses to decrease in absolute dollars for the three months ending March 31, 2024 as a 
result of the absence of additional rent expense associated with the partial termination of our Seattle lease that was recorded in 
the three months ended December 31, 2023, as discussed above.  

Impairment and Restructuring Costs 

Impairment and restructuring costs were $19 million and $24 million for the years ended December 31, 2023 and 2022, 

respectively. The year ended December 31, 2023 includes impairment costs of $16 million associated with changes in the use of 
certain office spaces in our lease portfolio and employee termination costs of $3 million. For additional information regarding 
impairment costs, see Note 10 of our Notes to Consolidated Financial Statements in Part II, Item 8 of this Annual Report on 
Form 10-K. 

Impairment and restructuring costs for the year ended December 31, 2022 do not qualify as discontinued operations and 

were primarily attributable to employee termination costs associated with the wind down of Zillow Offers operations. For 
additional information regarding these costs, see Note 3 of our Notes to Consolidated Financial Statements in Part II, Item 8 of 
this Annual Report on Form 10-K. 

Other Income, net 

Other income, net consists primarily of interest income earned on our cash, cash equivalents and investments, and fair 

value adjustments on an outstanding warrant. 

Other income, net increased $108 million, for the year ended December 31, 2023 as compared to the December 31, 2022. 

The increase in other income, net was primarily driven by increases in returns on investments due to the higher interest rate 
environment as compared to the prior year period. 

Income Taxes  

We are primarily subject to income taxes in the United States (federal and state), as well as certain foreign jurisdictions. 
As of December 31, 2023 and December 31, 2022, 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.  

We recorded income tax expense of $4 million and $3 million for the years ended December 31, 2023 and 2022, 

respectively, primarily driven by state taxes. Refer to Note 12 of our Notes to Consolidated Financial Statements in Part II, Item 
8 of this Annual Report on Form 10-K for additional information on our income taxes. 

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 

56 

 
 
obligations. 

Sources of Liquidity 

As of December 31, 2023 and 2022, we had cash and cash equivalents, investments and restricted cash of $2.8 billion and 

$3.4 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 held in escrow related to indemnification holdbacks for certain of our acquisitions and 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 December 31, 2023, 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 cash flows related to discontinued operations have not been separated. Accordingly, the consolidated statements of 

cash flows and the following discussions include the results of continuing and discontinued operations for the year ended 
December 31, 2022. There were no cash flows related to discontinued operations for the year ended December 31, 2023. See 
Note 3 in our Notes to Consolidated Financial Statements in Part II, Item 8 of this Annual Report on Form 10-K for additional 
information on discontinued operations, including supplemental cash flow information. The following table presents selected 
cash flow data for the periods presented (in millions):

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 and, prior to September 30, 2022, from customers for sales of homes through Zillow Offers. 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. Prior to the wind down of Zillow 
Offers operations, our primary uses of cash from operating activities also included payments for homes purchased through 
Zillow Offers. 

For the year ended December 31, 2023, net cash provided by operating activities was $354 million. This was primarily 

driven by a net loss of $158 million, adjusted by share-based compensation expense of $451 million, depreciation and 
amortization expense of $187 million, accretion of bond discount of $35 million, amortization of right of use assets of $35 
million, amortization of contract cost assets of $21 million, impairment costs of $16 million, and amortization of debt issuance 
costs of $5 million. Changes in operating assets and liabilities decreased cash provided by operating activities by $165 million. 
The changes in operating assets and liabilities are primarily related to a $59 million increase in mortgage loans held for sale due 
to an increase in purchase loan origination volume, a $30 million decrease in lease liabilities primarily due to contractual lease 

57 

 
 
  
  
 
 
   
 
 
payments, a $24 million increase in accounts receivable primarily due to an increase in revenue from products and services 
billed in arrears, a $21 million increase in contract cost assets primarily due to capitalized sales commissions, an $18 million 
decrease in accrued expenses and other current liabilities driven by the timing of payments, a $17 million increase in prepaid 
expenses and other current assets primarily due to an increase in revenue from products and services billed in arrears, and a $2 
million decrease in other long-term liabilities. These changes were partially offset by a $6 million increase in accounts payable 
driven by the timing of payments. 

For the year ended December 31, 2022, net cash provided by operating activities was $4.5 billion. This was primarily 

driven by a net loss of $101 million, adjusted by share-based compensation expense of $451 million, depreciation and 
amortization expense of $157 million, amortization of contract cost assets of $30 million, amortization of debt discount and 
debt issuance costs of $26 million, amortization of right of use assets of $23 million, a loss on extinguishment of debt of $21 
million, other adjustments to reconcile net loss to net cash provided by operating activities of $15 million, and an inventory 
valuation adjustment of $9 million. This was partially offset by $18 million in accretion of bond discount. Changes in operating 
assets and liabilities increased cash provided by operating activities by $3.9 billion. The changes in operating assets and 
liabilities are primarily related to a $3.9 billion decrease in inventory and an $82 million decrease in accounts receivable as we 
wound down Zillow Offers operations, a $66 million decrease in mortgage loans held for sale driven by increased interest rates 
which decreased demand for mortgages, a $6 million decrease in prepaid expenses and other current assets due to the timing of 
payments and a $7 million increase in other long-term liabilities primarily due to our outstanding warrant agreement. These 
changes were partially offset by a $71 million decrease in accrued expenses and other current liabilities and a $60 million 
decrease in accrued compensation and benefits driven primarily by the wind down of Zillow Offers operations, a $21 million 
decrease in lease liabilities primarily due to lease payments, an $18 million increase in contract cost assets and a $7 million 
decrease in deferred revenue. 

Cash Flows Provided By (Used In) Investing Activities 

Our primary investing activities include the purchase and sale or maturity of investments, the purchase of property and 

equipment and intangible assets, and cash paid in connection with acquisitions. 

For the year ended December 31, 2023, net cash provided by investing activities was $25 million. This was the result of 
$623 million of net proceeds from the maturity of investments, $433 million of cash paid for acquisitions, net of cash acquired, 
and $165 million of purchases of property and equipment and intangible assets. 

For the year ended December 31, 2022, net cash used in investing activities was $1.5 billion. This was primarily the 

result of $1.4 billion of net purchases of investments and $140 million of purchases of property and equipment and intangible 
assets. 

Cash Flows Used In Financing Activities 

Our primary financing activities have resulted from proceeds from the issuance of Class C capital stock, repurchases of 

Class A common stock and Class C capital stock, the exercise of employee option awards, repayments of borrowings on the 
warehouse line of credit and master repurchase agreements related to Zillow Home Loans, settlement of long term debt 
including repurchases of the 2025 Notes, and, prior to September 30, 2022, our Zillow Offers securitization term loans, 
proceeds from our Zillow Offers securitization transaction, and proceeds from and repayments of borrowings on our credit 
facilities related to Zillow Offers.  

For the year ended December 31, 2023, cash used in financing activities was $352 million, which was primarily related to  

$424 million of cash paid for share repurchases and $56 million for the repurchases of the 2025 Notes. These cash outflows 
were partially offset by $72 million of proceeds from the exercise of option awards and $56 million of net borrowings on our 
warehouse line of credit and master repurchase agreements related to Zillow Home Loans. 

For the year ended December 31, 2022, cash used in financing activities was $4.3 billion, which was primarily related to 
$2.2 billion of repayments on borrowings of our credit facilities and $1.2 billion for the repayment of the term loans associated 
with the wind down of Zillow Offers operations, $947 million of cash paid for share repurchases and $76 million of net 

58 

 
 
repayments on our warehouse line of credit and master repurchase agreements related to Zillow Home Loans. These cash 
outflows were partially offset by $46 million of proceeds from the exercise of option awards. 

Capital Resources 

Convertible Senior Notes 

As of December 31, 2023, we have a total of $1.6 billion aggregate principal amount of convertible senior notes 

outstanding. The convertible notes are senior unsecured obligations, and interest on the convertible notes is paid semi-annually. 
The following table summarizes our convertible senior notes as of the periods presented (in millions, except interest rates):

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. During the year ended December 31, 2023, 
we repurchased a total of $58 million aggregate principal amount of the 2025 Notes through open market transactions for 
$57 million in cash, including accrued interest. There were no repurchases of convertible senior notes during the year ended 
December 31, 2022. Refer to Note 11 of our Notes to Consolidated Financial Statements in Part II, Item 8 of this Annual Report 
on Form 10-K for additional information regarding our convertible senior notes, including conversion rates, conversion and 
redemption dates and the related capped call transactions. 

Share Repurchases 

Prior to the year ended December 31, 2023, the Board authorized the repurchase of up to $1.8 billion our Class A 

common stock, Class C capital stock, outstanding convertible senior notes or a combination thereof. On July 31, 2023, the 
Board authorized the repurchase of up to an additional $750 million of Class A common stock, Class C capital stock, 
outstanding convertible senior notes or a combination thereof. This additional authorization (together with the previous 
authorizations, the “Repurchase Authorizations”) increased our total cumulative Repurchase Authorizations to $2.5 billion. The 
Repurchase Authorizations do not have an expiration date. During the year ended December 31, 2023, we repurchased 2.2 
million shares of Class A common stock and 7.3 million shares of Class C capital stock at an average price of $46.45 and 
$43.94 per share, respectively, for an aggregate purchase price of $103 million and $321 million, respectively. As of December 
31, 2023, after the effects of our cumulative share and convertible debt repurchases, $770 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 repurchases made in accordance with the Repurchase Authorizations, see Note 11 and 
Note 13 in our Notes to Consolidated Financial Statements in Part II, Item 8 of this Annual Report on Form 10-K. 

Acquisitions 

We may enter into agreements to acquire businesses and may use available cash or proceeds from the issuance of debt or 

59 

 
 
 
 
 
  
 
 
   
   
equity securities to finance such transactions. On July 31, 2023, we acquired Aryeo for approximately $20 million of our Class 
C capital stock and $15 million in cash, net of cash acquired. On September 11, 2023, we acquired substantially all of the assets 
and liabilities of Spruce for approximately $19 million in cash, net of cash acquired. On December 8, 2023, we acquired Follow 
Up Boss for $399 million in cash, net of cash acquired, and up to $100 million in cash payable over a three-year period upon 
achievement of certain performance metrics contemplated by the purchase agreement. For additional information on these 
acquisitions, see Note 7 in our Notes to Consolidated Financial Statements in Part II, Item 8 of this Annual Report on Form 10-
K. 

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 warehouse line of credit and master repurchase agreements as of the periods

Contractual Obligations and Other Commitments 

Convertible Senior Notes - Includes the aggregate principal amounts of the 2024 Notes, 2025 Notes and 2026 Notes due 
on their contractual maturity dates, as well as the associated coupon interest. As of December 31, 2023, 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 convertible senior notes total $46 million, with $25 million payable within 12 months. Refer to Note 11 of 
our Notes to Consolidated Financial Statements in Part II, Item 8 of this Annual Report on Form 10-K for maturity dates, stated 
interest rates and additional information on our convertible senior 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 December 31, 2023, we have outstanding 
principal amounts of $93 million. Amounts exclude an immaterial amount of estimated interest payments. 

Operating Lease Obligations - Our lease portfolio primarily comprises operating leases for our office space. For 

60 

 
 
 
 
 
   
   
 
   
   
 
 
additional information regarding our operating leases and associated obligations, see Note 10 to our Notes to Consolidated 
Financial Statements in Part II, Item 8 of this Annual Report on Form 10-K. Additionally, as of December 31, 2023, 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 4 and Note 7 of our Notes to Consolidated Financial Statements in Part II, 
Item 8 of this Annual Report on Form 10-K. 

Purchase Obligations - We have non-cancellable purchase obligations for content related to our mobile applications and 
websites and certain cloud computing costs. For additional information regarding our purchase obligations, see Note 16 to our 
Notes to Consolidated Financial Statements in Part II, Item 8 of this Annual Report on Form 10-K. 

Critical Accounting Estimates  

Our consolidated financial statements are prepared in accordance with GAAP. The preparation of these 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. 

We believe that the estimates, judgments and assumptions associated with accounting for certain revenue offerings, 
website and software development costs, business combinations,  including the initial and subsequent fair value measurements 
of assets (primarily intangible assets), liabilities and contingent consideration, recoverability of intangible assets with definite 
lives and other long-lived assets, recoverability of goodwill and share-based compensation have the greatest potential impact on 
our consolidated financial statements. Therefore, we consider these to be our critical accounting estimates. 

Accounting for Certain Revenue 

Accrued Revenue. We accrue revenue for certain of our products, primarily our Premier Agent Flex, rentals pay per lease 

(“Zillow Lease Connect”) and StreetEasy Experts offerings. With these pricing models, our customers are provided with leads 
at no initial cost and pay a performance advertising fee only when a real estate transaction is closed, generally within two years, 
or a lease is secured with one of the leads we have provided, generally within six months. With these pricing models, the 
transaction price represents variable consideration, as the amount to which we expect to be entitled varies based on the number 
of leads that convert into closed real estate transactions or secured leases and the value of those transactions. As of December 
31, 2023, we accrued $90 million in revenue associated with these products. 

Although we do not believe that a significant reversal in the amount of cumulative revenue recognized will occur once 

the uncertainty related to the number of real estate transactions to be closed and qualified leases to be secured is resolved, 
judgment is required to determine the quantity and value of transactions and leases that are expected to be realized in a future 
period based on the number of leads delivered during the current period. Our estimated revenue is based on a number of 
assumptions, which include estimating the conversion rate of a lead to a real estate transaction or qualified lease, estimating the 
velocity of conversions and estimating the fee amounts likely to be received. Estimates are primarily developed based on 
historical data and our future expectations based on current market trends. 

Mortgage Origination Revenue. Mortgage origination revenue generated by Zillow Home Loans reflects origination fees 

on purchase or refinance mortgages and the corresponding sale, or expected future sale, of a loan. When an interest rate lock 
commitment is made to a customer, we record the expected gain on sale of the mortgage, plus the estimated earnings from the 
expected sale of the associated servicing rights, adjusted for a pull-through percentage (which represents the probability that an 
interest rate lock commitment will ultimately result in a closed loan), as revenue. Judgment is required to determine the 

61 

 
 
appropriate pull-through rate, which is estimated based on expected changes in market conditions, loan stage and historical 
borrower behavior. Revenue from loan origination fees is recognized at the time the related purchase or refinance transactions 
are completed, usually upon the close of escrow and when we fund the purchase or refinance mortgage loans. (cid:3)

Website and Software Development Costs  

The costs incurred in the preliminary stages of website and software development are expensed as incurred. Once an 

application has reached the development stage, internal and external costs, if direct and incremental and deemed by 
management to be significant, are capitalized in property and equipment and amortized on a straight-line basis over their 
estimated useful lives. Maintenance and enhancement costs, including those costs in the post-implementation stages, are 
typically expensed as incurred, unless such costs relate to substantial upgrades and enhancements to the website or software that 
result in added functionality, in which case the costs are capitalized and amortized on a straight-line basis over the estimated 
useful lives.  

Capitalized development activities placed in service are amortized over the expected useful lives of those releases, 
currently estimated at one to five years. The estimated useful lives of website and software development activities are reviewed 
frequently and adjusted as appropriate to reflect upcoming development activities that may include significant upgrades and/or 
enhancements to the existing functionality. 

We exercise judgment in determining the point at which various projects may be capitalized, in assessing the ongoing 
value of the capitalized costs and in determining the estimated useful lives over which the costs are amortized. To the extent 
that we change the manner in which we develop and test new features and functionalities related to our mobile applications and 
websites, assess the ongoing value of capitalized assets, or determine the estimated useful lives over which the costs are 
amortized, the amount of website and software development costs we capitalize and amortize could change in future periods. 

Recoverability of Intangible Assets with Definite Lives and Other Long-Lived Assets 

We evaluate intangible assets and other long-lived assets, including our lease right of use assets, for impairment whenever 

events or circumstances indicate that they may not be recoverable. Recoverability is measured by comparing the carrying 
amount of an asset group to future undiscounted net cash flows expected to be generated. We group assets for purposes of such 
review at the lowest level for which identifiable cash flows of the asset group are largely independent of the cash flows of the 
other groups of assets and liabilities.  

Unforeseen events, changes in circumstances and market conditions and material differences in estimates of future cash 
flows could adversely affect the fair value of our assets and could result in an impairment charge. Fair value can be estimated 
utilizing a number of techniques including quoted market prices, prices for comparable assets or other valuation processes 
involving estimates of cash flows, multiples of earnings or revenues, and we may make various assumptions and estimates 
when performing our impairment assessments, particularly as it relates to cash flow projections. Cash flow estimates are by 
their nature subjective and include assumptions regarding factors such as recent and forecasted operating performance, revenue 
trends and operating margins. These estimates could also be adversely impacted by changes in federal, state, or local 
regulations, economic downturns or developments, or other market conditions affecting our industry. 

Business Combinations 

We recognize identifiable assets acquired and liabilities assumed at their acquisition date fair values. Goodwill as of the 

acquisition date is measured as the excess of consideration transferred over the net of the acquisition date fair values of the 
assets acquired and liabilities assumed. We use assumptions and estimates in determining the fair value of assets acquired and 
liabilities assumed. Particularly, to estimate the fair value of acquired intangible assets, we engage third-party valuation 
specialists, and generally use valuation models that include variations of the income approach, specifically the excess earnings 
method and relief-from-royalty method. Under these valuation approaches, we are required to make estimates and assumptions 
which may include revenue growth rates, estimated earnings, royalty rates, obsolescence factors, customer attrition and 
discount rates. Changes in any of the inputs may result in a significantly different fair value. We may refine our estimates 
during the measurement period, which is up to one year from the acquisition date. Upon the conclusion of the measurement 

62 

 
 
period, any subsequent adjustments are recorded in our consolidated statements of operations. 

The acquisition of Follow Up Boss includes the potential for the future payment of consideration that is contingent upon 

the achievement of certain performance metrics. The fair value of contingent consideration is recorded as a liability in our 
consolidated balance sheets and is estimated at the acquisition date using a Monte Carlo simulation and unobservable inputs. 
These inputs include the probabilities of the achievement of certain performance metrics and the related discount rates. We may 
refine our acquisition date estimates during the measurement period, which is up to one year from the acquisition date. 
Subsequent to the acquisition date, at each reporting period until the contingencies are resolved, the contingent consideration is 
remeasured at current fair value with changes recorded in our consolidated statements of operations. Changes in any of the 
inputs may result in a significant fair value adjustment. 

Recoverability of Goodwill 

Goodwill is measured as the excess of consideration transferred for an acquired business over the net of the acquisition 

date fair value of the assets acquired and liabilities assumed, and is not amortized. We assess the impairment of goodwill at the 
reporting unit level on an annual basis, in our fourth quarter, or whenever events or changes in circumstances indicate that 
goodwill may be impaired. In our evaluation of goodwill, we first perform a qualitative assessment to determine whether the 
carrying value of our reporting unit is greater than its fair value. If it is more likely than not that the carrying value of the 
reporting unit is greater than its fair value, we perform a quantitative assessment and an impairment charge is recorded in our 
consolidated statements of operations for the excess of carrying value of the reporting unit over its fair value. 

We exercise judgment in determining whether it is more likely than not that the carrying value of our reporting unit is 

greater than its fair value. The following events and circumstances are considered when performing the qualitative assessment: 

•  Macroeconomic conditions, industry and market considerations, and entity-specific conditions, such as changes in cost 

factors and financial performance; 

•  The amount by which the fair value of the reporting unit exceeded the carrying value as of the date of the most recent 

quantitative assessment; 

•  Changes in interest rates since the most recent quantitative assessment; 
•  Changes in our business or strategy since our most recent qualitative assessment; 
•  Changes in our market capitalization and overall enterprise value. 

The examples noted above are not all-inclusive, and we consider other relevant events and circumstances that affect 

the fair value of the reporting unit in determining whether to perform a quantitative assessment.  

Beginning in 2023, our chief operating decision maker, who is our chief executive officer, manages our business, makes 
operating decisions and evaluates operating performance on the basis of the company as a whole, instead of on a segment basis 
as he did prior to 2023. This aligns to our ongoing growth strategy and our intent to provide integrated customer solutions for 
all tasks and services related to facilitating real estate transactions. This resulted in revisions to the nature and substance of 
information regularly provided to and used by the chief operating decision maker. Accordingly, we have realigned our operating 
structure, resulting in a single operating and reportable segment. In line with this, the nature and substance of the information 
regularly provided to our segment manager similarly changed, and we determined that we have only one reporting unit. 
Because the segment change impacted the structure of our reporting units, we performed a qualitative goodwill impairment 
assessment immediately before and immediately after the change in reporting units. Based on those assessments, we determined 
it was more likely than not that the fair value of our current and legacy reporting units exceeded their respective carrying 
values. Therefore, we concluded that it was not necessary to perform a quantitative impairment test. At December 31, 2023, our 
total goodwill balance was $2.8 billion. 

Share-Based Compensation 

We measure compensation expense for all share-based awards at fair value on the date of grant and recognize 
compensation expense over the service period for awards expected to vest. We use the Black-Scholes-Merton option-pricing 

63 

 
 
model to determine the fair value for option awards and recognize compensation expense on a straight-line basis over the option 
awards’ vesting period.  

Determining the fair value of option awards at the grant date requires judgment. In valuing our option awards, we make 

assumptions about risk-free interest rates, dividend yields, volatility, and weighted-average expected lives. If any of the 
assumptions changes significantly, share-based compensation expense for future option awards may differ materially compared 
with the awards granted previously. When determining the grant date fair value of share-based awards, management also 
considers whether an adjustment is required to the observable market price or volatility of our Class C capital stock used in the 
valuation as a result of material non-public information. 

Risk-free interest rate. Risk-free interest rates are derived from U.S. Treasury securities as of the option award’s grant 

date. 

Expected dividend yields. Expected dividend yields are based on our historical dividend payments, which have been zero 

to date. 

Volatility. The expected volatility for our Class C capital stock is estimated using our historical volatility. 

Expected term. The weighted-average expected life of the option awards is estimated based on our historical exercise 

data. 

We will continue to use judgment in evaluating the expected volatility and expected terms utilized for our share-based 

compensation expense calculations on a prospective basis. We will also continue to use judgment when determining whether an 
adjustment is required to the observable market price or volatility as a result of material non-public information. Actual results, 
and future changes in estimates, may differ substantially from management’s current estimates. As we continue to accumulate 
additional data related to our Class C capital stock, we may have refinements to the estimates of our expected volatility and 
expected terms, which could materially impact our future share-based compensation expense. In future periods, we expect our 
share-based compensation expense to decrease as existing awards continue to vest over their respective periods and we focus on 
mitigating dilution as we issue new awards. 

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

For information about our recently adopted accounting standards and recently issued accounting standards not yet 
adopted, see Note 2 of the accompanying Notes to Consolidated Financial Statements in Part II, Item 8 of this Annual Report on 
Form 10-K.

Item 7A. 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 December 31, 2023, we had approximately $1.6 billion aggregate principal amount of convertible senior notes 

outstanding with maturities ranging from September 2024 through September 2026. All outstanding convertible senior 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 convertible senior 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 expedited sale of our loans. As of 
December 31, 2023, we had $93 million of outstanding borrowings on our master repurchase agreements. Borrowings on the 
master repurchase agreements bear interest at a floating rate based on Secured Overnight Financing Rate (“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 December 31, 2023. 

For additional details related to our credit facilities and convertible senior notes, see Note 11 to our Notes to Consolidated 

Financial Statements in Part II, Item 8 of this Annual Report on Form 10-K. 

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 beginning in 2022 and continuing during the year ended December 31, 2023. In 
response to ongoing inflationary pressures in the United States, the Federal Reserve has implemented a number of increases to 
the federal funds rate during 2022 and 2023. Despite inflation stabilizing 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 during 2023. 

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 

65 

 
 
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. 

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.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM  

To the shareholders and the Board of Directors of Zillow Group, Inc. 

Opinion on the Financial Statements 

We have audited the accompanying consolidated balance sheets of Zillow Group, Inc. (the “Company”) as of December 31, 
2023 and 2022, the related consolidated statements of operations, comprehensive loss, shareholders’ equity, and cash flows, for 
each of the three years in the period ended December 31, 2023, and the related notes (collectively referred to as the “financial 
statements”). In our opinion, the financial statements present fairly, in all material respects, the financial position of the 
Company as of December 31, 2023 and 2022, and the results of its operations and its cash flows for each of the three years in 
the period ended December 31, 2023, in conformity with accounting principles generally accepted in the United States of 
America. 

We have also audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States) 
(PCAOB), the Company’s internal control over financial reporting as of December 31, 2023, based on criteria established in 
Internal Control — Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway 
Commission and our report dated February 14, 2024, expressed an unqualified opinion on the Company’s internal control over 
financial reporting. 

Basis for Opinion 

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

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

Critical Audit Matter 

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

Residential and Rentals Revenue – Processed and Recorded using Highly Automated Systems — Refer to Notes 2 and 18 to 
the Consolidated Financial Statements 

Critical Audit Matter Description 

The Company’s Residential and Rentals revenue transactions include a significant volume of data that are processed and 
recorded using multiple highly automated systems. Residential revenue includes revenue generated from the Premier Agent and 
new construction marketplaces, as well as revenue from the sale of advertising and business technology solutions for real estate 
professionals. Rentals revenue includes the sale of advertising and a suite of tools sold to property managers, landlords and 
other marketplace participants. 

68 

 
 
The Company’s systems to process and record certain Residential and Rentals revenue transactions are highly automated, rely 
on multiple internally developed systems, and involve interfacing significant volumes of data across the systems. Given the 
complexity of the information technology (IT) environment, the required involvement of professionals with expertise in IT to 
identify, test, and evaluate the revenue data flows, systems, and automated controls, we considered the audit of certain 
Residential and Rentals revenue transactions processed and recorded using highly automated systems to be a critical audit 
matter. 

How the Critical Audit Matter Was Addressed in the Audit 

Our audit procedures related to certain Residential and Rentals revenue transactions that are processed and recorded using 
highly automated systems included the following, among others: 

•  With the assistance of our IT specialists, we: 

(cid:405) 

Identified the relevant systems used to calculate and record revenue transactions. 

(cid:405)  Tested the general IT controls over the relevant systems, including testing of user access controls, change 

management controls, and IT operations controls. 

(cid:405) 

Performed testing of system interface controls and automated controls within the relevant revenue streams. 

•  We tested controls within the relevant business processes, including those in place to reconcile the transactional data 

from relevant systems to the Company’s general ledger. 

•  We reconciled the transactional data from relevant systems to the Company’s general ledger. 

• 

• 

For a sample of select revenue transactions, we performed detail testing of transactions by agreeing the amounts 
recognized to source documents and testing the mathematical accuracy of the recorded revenue. 

For select Premier Agent revenue transactions included within Residential revenue, we tested the amount of revenue 
recorded by developing an expectation for the amount by applying the percentage change from an independent 
variable to historical amounts recorded and comparing our expectation to the amount recorded by management.

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.(cid:3)

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.  

In the fourth quarter of 2021, we began to wind down the operations of Zillow Offers, our iBuying business which 
purchased and sold homes directly in markets across the country. The wind down was completed in the third quarter of 2022, 
and we have presented the financial results of Zillow Offers as discontinued operations in our consolidated statements of 
operations for the years ended December 31, 2022 and 2021. See Note 3 for additional information. 

Certain Significant Risks and Uncertainties 

We operate in a dynamic industry and, accordingly, can be affected by a variety of factors. 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 

77 

 
 
 
 
 
 
 
 
 
government investigations; our ability to manage advertising inventory and pricing and maintain relationships with our real 
estate partners; our compliance with multiple listing service rules and requirements to access and use listing data, and to 
maintain or establish relationships with listings 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 and retain a highly skilled workforce; protection of Zillow’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 consolidated financial statements include Zillow Group, Inc. and its wholly-owned subsidiaries. All 
intercompany balances and transactions have been eliminated in consolidation. These consolidated financial statements have 
been prepared in conformity with United States generally accepted accounting principles (“GAAP”). We have presented the 
financial results of Zillow Offers as discontinued operations in our consolidated financial statements for all periods presented as 
applicable. See Note 3 for additional information. Certain reclassifications of prior period amounts have been made to conform 
to the current period presentation.(cid:3)

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, restructuring costs, 
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, the presentation of discontinued and continuing 
operations, 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 the broader economy have introduced significant additional uncertainty with 
respect to estimates, judgments and assumptions, which may materially impact the estimates previously listed, among others. 

Concentrations of Credit Risk 

Financial instruments, which potentially subject us to concentrations of credit risk, consist primarily of cash and cash 

equivalents, investments, accounts receivable and mortgage loans held for sale. We place cash and cash equivalents and 
investments with major financial institutions, which management assesses to be of high credit quality, in order to limit exposure 
of our investments.  

Credit risk with respect to accounts receivable is dispersed due to the large number of customers. There were no 
customers that comprised 10% or more of our total accounts receivable as of December 31, 2023 or 2022. Further, our credit 
risk on accounts receivable is mitigated by the relatively short payment terms that we offer. Collateral is not required for 
accounts receivable. We maintain an allowance for doubtful accounts such that receivables are stated at net realizable value.  

Similarly, our credit risk on mortgage loans held for sale is dispersed due to a large number of customers and is mitigated 

by the fact that we typically sell mortgages on the secondary market within a relatively short period of time after the loan is 
originated. 

78 

 
 
Cash and Cash Equivalents 

Cash includes demand deposits with banks or financial institutions. Cash equivalents include short-term, highly liquid 
investments that are both readily convertible to known amounts of cash, and so near their maturity that they present minimal 
risk of changes in value because of changes in interest rates. Our cash equivalents include only investments with original 
maturities of three months or less. We regularly maintain cash in excess of federally insured limits at financial institutions. 

Short-term Investments 

Our investments consist of fixed income securities, which include U.S. government treasury securities, investment grade 
corporate securities, U.S. government agency securities and commercial paper. The investments are available to support current 
operations and are classified as short-term investments measured at fair value. Our investment policy only allows for purchases 
of investment-grade securities and provides guidelines on concentrations to ensure minimum risk of loss. We evaluate whether 
unrealized losses on available-for-sale debt securities are the result of credit worthiness of the securities held or other non-credit 
related factors. If an unrealized loss is the result of credit quality factors, we recognize an allowance reflective of our current 
estimate of credit losses expected to be incurred over the life of the financial instrument on a specific identification basis upon 
initial recognition and at each reporting period. If a reduction in value is a result of other factors, we continue to classify the 
losses in comprehensive loss unless either we intend to sell the security or it is more likely than not we will be required to sell 
the security. We did not identify any unrealized loss positions in our available-for-sale securities that were the result of credit 
losses as of December 31, 2023 or 2022. Additionally, we have the ability to hold our investments to maturity and more likely 
than not will not be required to sell the securities before a recovery of the amortized cost basis has occurred.(cid:3)

Restricted Cash 

Restricted cash primarily consists of amounts held in escrow related to indemnification holdbacks for certain of our 

acquisitions and amounts used to fund customer home purchases in our mortgage origination business.  

Mortgage Loans Held for Sale 

Mortgage loans held for sale include residential mortgages originated for sale in the secondary market in connection with 

our mortgage origination business. We have elected the fair value option for all mortgage loans held for sale as election of this 
option allows for a better offset of the changes in fair values of the loans and the derivative instruments used to economically 
hedge them without having to apply complex hedge accounting provisions. Mortgage loans held for sale are initially recorded at 
fair value based on either sale commitments or current market quotes and are adjusted for subsequent changes in fair value until 
the loans are sold. Net origination costs and fees associated with mortgage loans are recognized as incurred. We sell 
substantially all of the mortgages we originate and the related servicing rights to third-party purchasers. Interest income is 
earned from the date a mortgage loan is originated until the loan is sold and is classified within other income, net in the 
consolidated statements of operations. 

Substantially all of the mortgage loans originated are sold within a short period of time in the secondary mortgage market 

on a servicing released, nonrecourse basis, which limits exposure to nonperformance by loan buyer counterparties. However, 
we remain liable for certain limited representations and warranties related to loan sales, such as non-compliance with defined 
loan origination or documentation standards, including misstatement in the loan documents, early payoff or default on early 
payments. Mortgage investors could seek to have us buy back loans or compensate them for losses incurred on mortgages we 
have sold based on claims that we breached our limited representations and warranties. We record a reserve for probable losses 
in connection with the sale of mortgage loans within accrued expenses and other current liabilities in the consolidated balance 
sheet. 

Loan Commitments and Related Derivatives 

We are party to interest rate lock commitments (“IRLCs”), which are extended to borrowers who have applied for loan 

funding and meet defined credit and underwriting criteria in connection with our Zillow Home Loans mortgage origination 
business. IRLCs are accounted for as derivative instruments recorded at fair value with gains and losses recognized in revenue 
in the consolidated statements of operations. We manage our interest rate risk related to IRLCs and mortgage loans held for sale 

79 

 
 
through the use of derivative instruments, generally forward contracts on mortgage-backed securities (“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 consolidated statements of 
operations, and the fair values are reflected in other current assets or other current liabilities, as applicable. Refer to Note 4 to 
our consolidated financial statements for additional information regarding IRLCs and related derivatives. 

There are no credit-risk-related contingent features within our derivative agreements, and counterparty risk is considered 

minimal. Gains and losses on IRLCs are substantially offset by corresponding gains or losses on forward contracts on MBSs 
and mandatory loan commitments. We are generally not exposed to variability in cash flows of derivative instruments for more 
than approximately 90 days. 

Contract Balances 

Accounts receivable represent our unconditional right to consideration. Accounts receivable are generally due within 30 
days and are recorded net of the allowance for doubtful accounts. We have an allowance for doubtful accounts for our accounts 
receivable balances, which represents our estimate of expected credit losses over the contractual life of the accounts receivable. 
To evaluate the adequacy of our allowance for doubtful accounts each reporting period, we analyze the accounts receivable 
balances with similar risk characteristics on a collective basis, considering factors such as the aging of receivable balances, 
payment terms, historical loss experience, current information and future expectations. Changes to the allowance for doubtful 
accounts are adjusted through credit loss expense, which is included in general and administrative expenses in the consolidated 
statements of operations. 

Contract assets represent our right to consideration in exchange for goods and services that we have transferred to the 
customer when that right is conditional on something other than the passage of time. Contract assets are primarily related to our 
Premier Agent Flex, Zillow Lease Connect and StreetEasy Experts offerings, whereby we estimate variable consideration based 
on the expected number of real estate transactions to be closed for Premier Agent Flex and StreetEasy Experts, and qualified 
leases to be secured for Zillow Lease Connect. We recognize revenue when we satisfy our performance obligations under the 
corresponding contracts. The current portion of contract assets are recorded within prepaid expenses and other current assets 
and the long-term portion of contract assets are recorded within other assets in our consolidated balance sheets. 

Contract liabilities consist of deferred revenue, which relates to payments received in advance of performance under a 
revenue contract. Deferred revenue is primarily related to prepaid advertising fees received or billed in advance of satisfying 
our performance obligations and prepaid but unrecognized subscription revenue. Deferred revenue is recognized when or as we 
satisfy our obligations under contracts with customers. 

Contract Cost Assets 

We capitalize certain incremental costs of obtaining contracts with customers which we expect to recover. These costs 

relate to commissions paid to sales personnel, primarily for our Premier Agent program. As a practical expedient, we recognize 
the incremental costs of obtaining a contract as an expense when incurred if the amortization period of the asset that we 
otherwise would have recognized is one year or less. Capitalized commission costs are recorded as contract cost assets in our 
consolidated balance sheets. Contract cost assets are amortized to expense on a straight-line basis over a period that is 
consistent with the transfer to the customer of the products or services to which the asset relates, generally the estimated life of 
the customer relationship. Amortization expense related to contract cost assets is included in sales and marketing expenses in 
our consolidated statements of operations. In determining the estimated life of our customer relationships, we consider 
quantitative and qualitative data, including, but not limited to, historical customer data, recent changes or expected changes in 
product or service offerings and changes in how we monetize our products and services. The amortization period for capitalized 
contract costs related to our Premier Agent program is approximately three years. 

We monitor our contract cost assets for impairment and recognize an impairment loss in the consolidated statements of 

operations to the extent the carrying amount of the asset recognized exceeds the amount of consideration that we expect to 

80 

 
 
receive in the future and that we have received but have not recognized in revenue less the costs that relate directly to providing 
those goods or services that have not yet been recognized as expenses. For the years ended December 31, 2023, 2022 and 2021, 
we did not record any material impairment losses to our contract cost assets. 

Property and Equipment 

Property and equipment is recorded at cost and depreciated using the straight-line method over the estimated useful lives 

of the related assets. The useful lives are as follows: 

Computer equipment 

3 years 

Office equipment, furniture and fixtures 

5 to 7 years 

Leasehold improvements 

Shorter of expected useful life or lease term 

Maintenance and repair costs are charged to expense as incurred. Major improvements, which extend the useful life of the 

related asset, are capitalized. Upon disposal of a fixed asset, we record a gain or loss based on the difference between the 
proceeds received and the net book value of the disposed asset. We remove fully depreciated property and equipment from the 
cost and accumulated depreciation amounts disclosed. 

Website and Software Development Costs 

Costs incurred in the preliminary stages of website and software development are expensed as incurred. Once an 

application has reached the development stage, internal and external costs, if direct and incremental and deemed by 
management to be significant, are capitalized in property and equipment and amortized on a straight-line basis over their 
estimated useful lives. Maintenance and enhancement costs, including those costs in the post-implementation stages, are 
typically expensed as incurred, unless such costs relate to substantial upgrades and enhancements to the website or software that 
result in added functionality, in which case the costs are capitalized and amortized on a straight-line basis over the estimated 
useful lives. Amortization expense related to capitalized website and software development costs is included in cost of revenue 
in our consolidated statements of operations. 

Capitalized development activities placed in service are amortized over the expected useful lives of those releases, 
currently estimated at one to five years. The estimated useful lives of website and software development activities are reviewed 
frequently and adjusted as appropriate to reflect upcoming development activities that may include significant upgrades and/or 
enhancements to the existing functionality. We remove fully amortized website and software development costs from the cost 
and accumulated amortization amounts disclosed. 

Construction-in-progress primarily consists of website development costs that are capitalizable, but for which the 

associated applications have not been placed in service.  

Leases 

Our lease portfolio is primarily composed of operating leases for our office space. We determine whether a contract is or 
contains a lease at inception of the contract. Our operating leases are included in right of use assets and lease liabilities on our 
consolidated balance sheets. We do not have any material financing leases. 

We have lease agreements that include both lease components (e.g., fixed rent) and non-lease components (e.g., common 
area maintenance). For such leases, we account for the lease and non-lease components as a single component. For leases with 
an initial term of 12 months or less, we recognize the associated lease payments in the consolidated statements of operations on 
a straight-line basis over the lease term. 

Right of use assets represent our right to use an underlying asset during the lease term and lease liabilities represent our 

obligation to make lease payments. Right of use assets and lease liabilities are recognized at the lease commencement date 
based on the present value of the total lease payments contracted but not yet paid, including lease incentives not yet received, 
with the right of use assets further adjusted for any prepaid or accrued lease payments, lease incentives received and/or initial 

81 

 
 
direct costs incurred. Certain lease arrangements also include variable payments for costs such as common-area maintenance, 
utilities, taxes or other operating costs, which are based on a percentage of actual expenses incurred or a fluctuating rate which 
is unknown at the inception of the contract. These variable lease payments are excluded from the measurement of the right of 
use assets and lease liabilities. 

Our leases have remaining lease terms ranging from less than one year to nine years, most of which include one or more 

options to extend the lease term. The renewal options can generally extend the lease term for up to an additional five to ten 
years. When determining if a renewal option is reasonably certain of being exercised at lease commencement, we consider 
several factors, including but not limited to, contract-based, asset-based and entity-based factors. We reassess the term of 
existing leases if there is a significant event or change in circumstances within our control that affects whether we are 
reasonably certain to exercise an option to extend a lease. Examples of such events or changes include construction of 
significant leasehold improvements or other modifications or customizations to the underlying asset, relevant business decisions 
or subleases. As of December 31, 2023, we have concluded that our renewal options are not reasonably certain of being 
exercised, therefore, renewal options are not included in the right of use assets and lease liabilities. 

As our leases do not provide an implicit rate, we use our incremental borrowing rate based on the information available at 

the lease commencement date in determining the present value of the lease payments. We apply a portfolio approach for 
determining the incremental borrowing rate based on the applicable lease terms and the current economic environment. 

We recognize lease expense for operating leases on a straight-line basis over the lease term. Variable lease payments are 

generally recognized when incurred. These expenses are included in general and administrative expenses in the consolidated 
statements of operations. 

From time to time, we may enter into sublease agreements with third parties. Our subleases generally do not relieve us of 

our primary obligations under the corresponding head lease. As a result, we account for the head lease based on the original 
assessment at lease inception. We determine if the sublease arrangement is either a sales-type, direct financing, or operating 
lease at inception of the sublease. If the total remaining lease cost on the head lease for the term of the sublease is greater than 
the anticipated sublease income, the right of use asset is assessed for impairment. Our subleases are generally operating leases 
and we recognize sublease income on a straight-line basis over the sublease term as a reduction to our operating lease cost 
within general and administrative expenses in our consolidated statements of operations. 

Recoverability of Goodwill 

Goodwill is measured as the excess of consideration transferred for an acquired business over the net of the acquisition 

date fair values of the assets acquired and the liabilities assumed, and is not amortized. We assess the impairment of goodwill at 
the reporting unit level on an annual basis, in our fourth quarter, or whenever events or changes in circumstances indicate that 
goodwill may be impaired. In our evaluation of goodwill, we initially perform a qualitative assessment to determine whether 
the existence of events or circumstances indicates that it is more likely than not that the carrying value of each reporting unit is 
greater than its fair value. If it is more likely than not that the carrying value of a reporting unit is greater than its fair value, we 
perform a quantitative assessment and an impairment charge is recorded in our statements of operations if the carrying value of 
the reporting unit exceeds its fair value.  

Beginning in 2023, our chief operating decision maker, who is our chief executive officer, manages our business, makes 
operating decisions and evaluates operating performance on the basis of the company as a whole, instead of on a segment basis 
as he did prior to 2023. This aligns to our ongoing growth strategy and our intent to provide integrated customer solutions for 
all tasks and services related to facilitating real estate transactions. This resulted in revisions to the nature and substance of 
information regularly provided to and used by the chief operating decision maker. Accordingly, we have realigned our operating 
structure, resulting in a single operating and reportable segment. In line with this, the nature and substance of the information 
regularly provided to our segment manager similarly changed, and we determined that we have only one reporting unit. 
Because the segment change impacted the structure of our reporting units, we performed a qualitative goodwill impairment 
assessment immediately before and immediately after the change in reporting units. Based on those assessments, we determined 
it was more likely than not that the fair value of our current and legacy reporting units exceeded their respective carrying 
values. Therefore, we concluded that it was not necessary to perform a quantitative impairment test. During the years ended 

82 

 
 
December 31, 2023, 2022 and 2021, we did not record any impairments related to goodwill. 

Intangible Assets 

We purchase and license data content from multiple data providers. This data content consists of United States county 
data about home details and other information relating to the purchase price of homes, both current and historical, as well as 
imagery, mapping and parcel data that is displayed on our mobile applications and websites. In some instances, we retain 
perpetual rights to this information after our contract with a vendor ends; in other instances, the information and data are 
licensed only during the fixed term of the agreement. Additionally, certain data license agreements provide for uneven payment 
amounts throughout the contract term.  

We capitalize payments made to third parties for data licenses that we expect to recover through generation of revenue 
and margins. For data license contracts that include uneven payment amounts, we capitalize the payments as they are made as 
an intangible asset and the total contract value is typically amortized on a straight-line basis over the term of the contract, which 
is equivalent to the estimated useful life of the asset. The amortization period for the capitalized purchased content is based on 
our best estimate of the useful life of the asset, which ranges from three to seven years.  

Under certain other data agreements, the underlying data is obtained on a subscription basis with consistent monthly or 
quarterly recurring payment terms over the contractual period. Upon the expiration of such arrangements, we no longer have 
the right to access the related data, and therefore, the costs incurred under such contracts are not capitalized and are expensed as 
payments are made. 

We also capitalize costs related to the license of certain internal-use software from third parties, including certain licenses 

of software in cloud computing arrangements. Additionally, we capitalize costs incurred during the application development 
stage related to the development of internal-use software and enterprise cloud computing services. We expense costs as incurred 
related to the planning and post-implementation phases of development. Capitalized internal-use software costs are amortized 
on a straight-line basis over the estimated useful life of the asset, which is currently one to five years. 

Intangibles-in-progress consist of purchased content and software that are capitalizable but have not been placed in 

service. 

We also have intangible assets for developed technology, customer relationships, and trade names and trademarks which 
we recorded in connection with acquisitions. Purchased intangible assets with a determinable economic life are carried at cost 
less accumulated amortization. These intangible assets are amortized over the estimated useful life of the asset on a straight-line 
basis. 

For each of the intangible assets described above, we have removed fully amortized assets from the cost and accumulated 

amortization amounts disclosed. 

Recoverability of Intangible Assets with Definite Lives and Other Long-Lived Assets 

We evaluate intangible assets and other long-lived assets, including our lease right of use assets, for impairment whenever 

events or circumstances indicate that they may not be recoverable. Recoverability is measured by comparing the carrying 
amount of an asset group to future undiscounted net cash flows expected to be generated. We group assets for purposes of such 
review at the lowest level for which identifiable cash flows of the asset group are largely independent of the cash flows of the 
other groups of assets and liabilities. If this comparison indicates impairment, the amount of impairment to be recognized is 
calculated as the difference between the carrying value and the fair value of the asset group. 

Business Combinations 

We recognize identifiable assets acquired and liabilities assumed at their acquisition date fair values. Goodwill as of the 

acquisition date is measured as the excess of consideration transferred over the net of the acquisition date fair values of the 
assets acquired and the liabilities assumed. While we use our best estimates and assumptions for the preliminary purchase price 
allocation process to value assets acquired and liabilities assumed at the acquisition date, our estimates are inherently uncertain 

83 

 
 
and subject to refinement. As a result, during the measurement period, which may be up to one year from the acquisition date, 
we record adjustments to the assets acquired and liabilities assumed, with the corresponding offset to goodwill to the extent that 
we identify adjustments to the preliminary purchase price allocation. Upon the conclusion of the measurement period or final 
determination of the values of assets acquired or liabilities assumed, whichever comes first, any subsequent adjustments are 
recorded to our consolidated statements of operations. We recognize adjustments to provisional amounts that are identified 
during the measurement period in the reporting period in which the adjustment amounts are determined. 

We record contingent consideration at its preliminary estimated fair value at the date of acquisition. The current portion 

of contingent consideration is recorded within accrued expenses and other current liabilities, and the long-term portion is 
recorded within other long-term liabilities in our consolidated balance sheets. The fair value of contingent consideration is 
remeasured each reporting period. Measurement period adjustments, if any, to the preliminary estimated fair value as of the 
acquisition date will be recorded to goodwill. Changes in fair value as a result of updated assumptions after the acquisition date 
will be recorded in general and administrative expenses in the consolidated statements of operations. 

Revenue Recognition 

We recognize revenue when or as we satisfy our performance obligations by transferring control of the promised products 
or services to our customers in an amount that reflects the consideration to which we expect to be entitled in exchange for those 
products or services. 

As a practical expedient, we do not adjust the promised amount of consideration for the effects of a significant financing 
component, as the period between our transfer of a promised product or service to a customer and when the customer pays for 
that product or service is generally one year or less, with the exception of certain of our pay for performance products, 
including Premier Agent Flex and StreetEasy Experts, whereby we may not receive payment for services provided for up to two 
years after control of the promised products or services is transferred to our customers. In these cases, however, because a 
substantial portion of the consideration is variable, we have concluded the contracts do not include a significant financing 
component. 

We do not disclose the transaction price related to remaining performance obligations for (i) contracts with an original 

expected duration of one year or less or (ii) contracts for which we recognize revenue at the amount to which we have the right 
to invoice for performance completed to date. The remaining duration over which we satisfy our performance obligations is 
generally less than one year. 

We disaggregate our revenue into the following categories: Residential, Rentals, Mortgages and Other, described below. 

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+, and upon acquisition on December 8, 2023, Follow Up Boss. 

Our Premier Agent program offers a suite of marketing and technology products and services to help real estate agents 

and brokers achieve their advertising goals while growing and managing their businesses and brands. All Premier Agent 
partners receive access to a dashboard portal on our mobile application and website that provides individualized program 
performance analytics, our customer relationship management tool that captures detailed information about each contact made 
with a Premier Agent partner through our mobile and web platforms and our account management tools. The marketing and 
business technology products and services promised to Premier Agent partners are delivered over time, as the customer 
simultaneously receives and consumes the benefit of the performance obligations. 

Premier Agent advertising 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. For our market-based pricing products and 
services, payment is received prior to the delivery of connections. Connections are delivered when consumer contact 
information is provided to Premier Agent partners. We do not promise any minimum or maximum number of connections to 
customers, but instead control when and how many connections to deliver based on a customer’s share of voice. We determine 
the number of connections to deliver to Premier Agent partners in each zip code using a market-based pricing method in 
consideration of the total amount spent by Premier Agent partners to purchase connections in the zip code during the month. 

84 

 
 
 
This results in the delivery of connections over time in proportion to each Premier Agent partners’ share of voice. A Premier 
Agent partners’ share of voice in a zip code is determined by their proportional monthly prepaid spend in that zip code as a 
percentage of the total monthly prepaid spend of all Premier Agent partners in that zip code, and determines the proportion of 
consumer connections a Premier Agent partner receives. The number of connections delivered for a given spend level is 
dynamic; as demand for advertising in a zip code increases or decreases, the number of connections delivered to a Premier 
Agent partner in that zip code decreases or increases accordingly. 

We recognize revenue related to Premier Agent market-based pricing products and services based on the monthly prepaid 

spend recognized on a straight-line basis during the monthly billing period over which the products and services are provided. 
This methodology best depicts how we satisfy our performance obligations to customers, as we continuously transfer control of 
the performance obligations to the customer over time. Given a Premier Agent partner typically prepays their monthly spend 
and the monthly spend is refunded on a pro-rata basis upon cancellation of the contract by a customer, we have determined that 
Premier Agent market-based pricing contracts are effectively daily contracts, and each performance obligation is satisfied over 
time as each day lapses. We have not allocated the transaction price to each performance obligation within our Premier Agent 
market-based pricing arrangements, as the amounts recognized would be the same irrespective of any allocation. 

Our pay for performance pricing model is called “Flex” and is available in certain markets to select partners. 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. With this pricing model, the 
transaction price represents variable consideration, as the amount to which we expect to be entitled varies based on the number 
of validated leads that convert into real estate transactions and the value of those transactions. We estimate variable 
consideration and record revenue as performance obligations, or validated leads, are transferred. We do not believe that a 
significant reversal in the amount of cumulative revenue recognized will occur once the uncertainty related to the number of 
transactions closed is subsequently resolved. We record a contract asset for our estimate of the consideration to which we will 
be entitled when the right to the consideration is conditional. When the right to consideration becomes unconditional, upon the 
close of a real estate transaction, we reclassify amounts to accounts receivable.  

Our new construction marketing solutions allow home builders to showcase their available inventory to home shoppers. 

New construction revenue primarily includes revenue generated by advertising sold to builders on a cost per residential 
community basis whereby we recognize revenue on a straight-line basis during the contractual period over which the 
communities are advertised on our mobile applications and websites. New construction revenue also includes revenue 
generated on a cost per impression basis whereby we recognize revenue as impressions are delivered to users interacting with 
our mobile applications and websites, which is the amount for which we have the right to invoice. Consideration for new 
construction products is billed in arrears. 

StreetEasy for-sale revenue primarily consists of our StreetEasy Experts and StreetEasy subscription offerings. 
StreetEasy Experts is our pay for performance pricing model available in the New York City market for which agents and 
brokers are provided with leads at no initial cost and pay a performance referral fee only when a real estate purchase transaction 
is closed with one of the leads. Under the StreetEasy Experts pricing model, the transaction price represents variable 
consideration, as the amount to which we expect to be entitled varies based on the number of leads that convert into real estate 
transactions and the value of those transactions. We estimate variable consideration based on the expected number of closed 
transactions during the period. We do not believe that a significant reversal in the amount of cumulative revenue recognized 
will occur once the uncertainty related to the number of transactions closed is subsequently resolved. We record a 
corresponding contract asset for the estimate of variable consideration for StreetEasy Experts when the right to the 
consideration is conditional. When the right to consideration becomes unconditional upon the close of a real estate transaction, 
we reclassify amounts to accounts receivable. 

Revenue generated through StreetEasy subscription offerings includes the sale of advertising and a suite of tools to 
developers, property managers, agents and other market professionals. Revenue from StreetEasy subscription offerings is 
generated on a cost per property basis, based on the property size and product tier, and we recognize revenue on a straight-line 
basis over the contractual listing period which aligns to our satisfaction of performance obligations. 

85 

 
 
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 revenue is 
primarily billed in advance on a monthly basis and recognized ratably over the contract period which aligns to our satisfaction 
of performance obligations. ShowingTime+ revenue also includes our dotloop real estate transaction management software-as-
a-service solution. Dotloop revenue is primarily billed in advance on a monthly basis and revenue is recognized ratably over the 
contract period which aligns to our satisfaction of performance obligations. 

Rentals. Rentals revenue includes the sale of advertising and a suite of tools to rental professionals, landlords and other 
market participants under the Zillow and StreetEasy brands. Rentals revenue includes revenue generated by advertising sold to 
property managers, landlords and other rental professionals on a cost per lead, lease, listing or impression basis or for a fixed 
fee for certain advertising packages. We recognize revenue as leads, clicks and impressions are provided to rental professionals, 
or as rental listings are published on our mobile applications and websites, which is the amount for which we have the right to 
invoice. We recognize revenue related to our fixed fee rentals product on a straight-line basis over the contract term as the 
performance obligations, rental listings on our mobile applications and websites, are satisfied over time. The number of leases 
generated through our rentals pay per lease product, Zillow Lease Connect, during the period is accounted for as variable 
consideration, and we estimate the amount of variable consideration based on the expected number of qualified leases secured 
during the period. We do not believe that a significant reversal in the amount of cumulative revenue recognized will occur once 
the uncertainty related to the number of leases secured is subsequently resolved. We record a contract asset for the estimate of 
variable consideration for Zillow Lease Connect when the right to the consideration is conditional. When the right to 
consideration becomes unconditional upon the execution of a lease, we reclassify amounts to accounts receivable. 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. We recognize revenue for the rental applications product on a straight-
line basis during the contractual period over which the customer has the right to access and submit the rental application. 

Mortgages. Mortgages revenue primarily includes revenue generated by Zillow Home Loans, our affiliated mortgage 

lender, and marketing products sold to mortgage professionals on a cost per lead basis, including our Custom Quote and 
Connect services.  

Mortgage origination revenue reflects origination fees on purchase or refinance mortgages and the corresponding sale, or 
expected future sale, of a loan. When an IRLC is made to a customer, we record the expected gain on sale of the mortgage, plus 
the estimated earnings from the expected sale of the associated servicing rights, adjusted for a pull-through percentage (which is 
defined as the likelihood that an IRLC will be originated), as revenue. Revenue from loan origination fees is recognized at the 
time the related purchase or refinance transactions are completed, usually upon the close of escrow and when we fund the 
purchase or refinance mortgage loans. Once funded, mortgage loans held for sale are recorded at fair value based on either sale 
commitments or current market quotes and are adjusted for subsequent changes in fair value until the loan is sold. Origination 
costs associated with originating mortgage loans are recognized as incurred. We sell substantially all of the mortgages we 
originate and the related servicing rights to third-party purchasers. 

Mortgage loans are sold with limited recourse provisions, which can result in repurchases of loans previously sold to 
investors or payments to reimburse investors for loan losses. Based on historical experience, discussions with our mortgage 
purchasers, analysis of the volume of mortgages we originated and current housing and credit market conditions, we estimate 
and record a loss reserve for mortgage loans held for sale, as well as known and projected mortgage loan repurchase requests. 
These have historically not been significant to our financial statements. 

Zillow Group operates Custom Quote and Connect through its wholly owned subsidiary, Zillow Group Marketplace, Inc., 

a licensed mortgage broker. For our Connect and Custom Quote cost per lead marketing products, participating qualified 
mortgage professionals typically make a prepayment to gain access to consumers interested in connecting with mortgage 
professionals. Mortgage professionals who exhaust their initial prepayment prepay additional funds to continue to participate in 
the marketplace. In Zillow Group’s Connect platform, consumers answer a series of questions to find a local lender, and 
mortgage professionals receive consumer contact information, or leads, when the consumer chooses to share their information 
with a lender. Consumers who request rates for mortgage loans in Custom Quotes are presented with customized quotes from 

86 

 
 
participating mortgage professionals. For our cost per lead mortgages products, we recognize revenue when a user contacts a 
mortgage professional through our mortgages platform, which is the amount for which we have the right to invoice. 

Other. Other revenue primarily includes revenue generated from display products, which consist of graphical mobile and 

web advertising sold on a cost per thousand impressions or cost per click basis to advertisers promoting their brands on our 
mobile applications and websites. We recognize display revenue as clicks occur or as impressions are delivered to users 
interacting with our mobile applications or websites, which is the amount for which we have the right to invoice. 

There were no customers that generated 10% or more of our total revenue in the years ended December 31, 2023, 2022 or 

2021. 

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 loans, including underwriting and 
processing costs. 

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.  

Advertising costs are expensed as incurred. For the years ended December 31, 2023, 2022 and 2021, expenses 

attributable to advertising totaled $137 million, $144 million and $206 million, respectively. 

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 software maintenance costs and depreciation expense. 

Research and development costs are expensed as incurred and are recorded in technology and development expenses. For 
the years ended December 31, 2023, 2022 and 2021, expenses attributable to research and development for our business totaled 
$545 million, $495 million and $358 million, respectively. 

Share-Based Compensation. We measure compensation expense for all share-based awards at fair value on the date of 

grant and recognize compensation expense over the service period on a straight-line basis for awards expected to vest. 

We use the Black-Scholes-Merton option-pricing model to determine the fair value for option awards. In valuing our 

option awards, we make assumptions about risk-free interest rates, dividend yields, volatility and weighted-average expected 
lives. We account for forfeitures as they occur. Risk-free interest rates are derived from U.S. Treasury securities as of the option 
award grant date. Expected dividend yield is based on our historical cash dividend payments, which have been zero to date. The 
expected volatility for our Class C capital stock is estimated using our historical volatility. The weighted-average expected life 
of the option awards is estimated based on our historical exercise data. 

When determining the grant date fair value of share-based awards, management considers whether an adjustment is 
required to the observable market price or volatility of the Company’s Class C capital stock used in the valuation as a result of 
material non-public information. 

For issuances of restricted stock units, we determine the fair value of the award based on the market value of our Class C 

87 

 
 
capital stock, as applicable, at the date of grant. 

Impairment and Restructuring Costs. From time to time, we record impairment costs within impairment and restructuring 
costs in our consolidated statements of operations. See Note 10 for additional information on the impairment costs recorded 
during the year ended December 31, 2023. 

The main components of our restructuring costs recorded within impairment and restructuring costs in our consolidated 
statements of operations relate to employee termination costs, contract termination costs, and charges attributable to the wind 
down of Zillow Offers operations and additional cost actions to streamline our operations and prioritize investments. One-time 
employee termination benefits are recognized when the plan of termination has been communicated to employees and certain 
other criteria are met. Other severance and employee costs, primarily pertaining to ongoing employee benefit arrangements, are 
recognized when it is probable that the employees are entitled to the severance benefits and the amounts can be reasonably 
estimated. Contract termination costs are recognized when a contract is terminated in accordance with its terms or at the cease-
use date. Asset write-offs are recognized upon their cease-use date. The cumulative effect of a change resulting from a revision 
to either the timing or the amount of estimated cash flows for restructuring is recognized as an adjustment to the liability in the 
period of the change. 

Income Taxes 

We use the asset and liability approach for accounting and reporting income taxes, which requires the recognition of 
deferred tax assets and liabilities for the expected future tax consequences of temporary differences between the financial 
statement and tax bases of assets and liabilities at the applicable enacted tax rates. A valuation allowance against deferred tax 
assets would be established if, based on the weight of available evidence, it is more likely than not (a likelihood of more than 
50%) that some or all of the deferred tax assets are not expected to be realized. 

We establish reserves for tax-related uncertainties based on estimates of whether, and the extent to which, additional taxes 

will be due. We adjust these reserves in light of changing facts and circumstances, such as the closing of a tax audit, new tax 
legislation or the change of an estimate. To the extent that the final tax outcome of these matters is different than the amounts 
recorded, such differences will affect the provision for income taxes in the period in which such determination is made. Interest 
and penalties related to unrecognized tax benefits are recorded as income tax expense. 

Recently Issued Accounting Standards Not Yet Adopted 

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 expect to adopt this guidance on January 1, 
2024, and we do not expect the adoption of this guidance to have a material impact on our financial position, results of 
operations or cash flows. 

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, 2024 using the retrospective approach and have not yet 
determined the impact the adoption of this guidance will have on our consolidated financial statements.

Note 3. Discontinued Operations 

Zillow Offers Wind Down 

In November 2021, the Board of Directors of Zillow Group (the “Board”) made the determination to wind down Zillow 
Offers operations. This decision was made in light of home pricing unpredictability, capacity constraints and other operational 
challenges faced by Zillow Offers that were exacerbated by an unprecedented housing market, a global pandemic and a difficult 
labor and supply chain environment, all of which led us to conclude that, despite its initial promise in earlier quarters, Zillow 
Offers was unlikely to be a sufficiently stable line of business to meet our goals going forward.  

The wind down of Zillow Offers was completed in the third quarter of 2022, at which time Zillow Offers met the criteria 

for discontinued operations. Accordingly, we have presented the results of operations, excluding allocation of any general 
corporate expenses, of Zillow Offers as discontinued operations in our consolidated statements of operations for the years ended 
December 31, 2022 and 2021. No assets or liabilities were classified as discontinued operations as of December 31, 2022.

$33 million. 

Note 4. Fair Value Measurements 

We apply fair value measurements on a recurring and, as otherwise required, on a nonrecurring basis. Accounting 
standards define fair value as the price that would be received to sell an asset or paid to transfer a liability (an exit price) in the 
principal or most advantageous market in an orderly transaction between market participants on the measurement date. The 
standards also establish a fair value hierarchy, which requires an entity to maximize the use of observable inputs and minimize 
the use of unobservable inputs when measuring fair value. There are three levels of inputs that may be used to measure fair 
value: 

•  Level 1 — Quoted prices in active markets for identical assets or liabilities. 
•  Level 2 — Assets and liabilities valued based on observable market data for similar instruments, such as quoted prices 

for similar assets or liabilities. 

•  Level 3 — Unobservable inputs that are supported by little or no market activity; instruments valued based on the best 
available data, some of which is internally developed, and considers risk premiums that a market participant would 
require. 

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). 

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). 

90 

 
 
 
 
 
 
 
 
 
 
 
 
 
 
Contingent consideration — In December 2023, Zillow Group acquired Enchant, LLC (“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). 

As of the acquisition date of Follow Up Boss, our preliminarily estimated fair value of the contingent consideration was 

approximately $81 million. There were no material changes to the fair value of the contingent consideration between the 
acquisition date and December 31, 2023. See Note 7 for additional details on our contingent consideration and measurement 
period adjustments.  

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. 

The following table presents the range and weighted average unobservable inputs used in determining the fair value of 

contingent consideration as of December 31, 2023:

Weighted average 

Discount Rate 

6.58% - 7.13% 

6.88%

Metrics

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 cancelled 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 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:

Note 7. 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 4 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):

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, primarily due to the limited amount of 
time between the acquisition closing date and December 31, 2023. 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, identifiable intangible assets and 
contingent consideration. As of December 31, 2023, 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 may be subject to 
revision as additional information is obtained which may result in adjustments to the preliminary estimated fair values 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 

consolidated financial statements.

Acquisitions of Aryeo and Spruce 

On July 31, 2023, Zillow Group acquired Aryeo, Inc. (“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 Holdings, Inc. and certain affiliated entities 
(collectively referred to as “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 preliminary 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 preliminary 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):

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. 

The purchase price allocation for the Aryeo and Spruce acquisitions is preliminary. We made an initial allocation of the 

purchase prices at the date of the acquisition based upon our understanding of the fair value of the acquired assets and assumed 
liabilities based on information currently available. As of December 31, 2023, the measurement period (not to extend one year) 
is open for the Aryeo and Spruce acquisition; therefore, the assets acquired and liabilities assumed are subject to adjustment 
until the end of the measurement period.

recognized $10 million, $10 million and $7 million, respectively, of sublease income. For the year ended December 31, 2023, 
we recognized impairment costs of $16 million within impairments and restructuring costs in our consolidated statements of 
operations associated with changes in the use of certain office spaces, primarily related to subleases where anticipated sublease 
income was less than the carrying value of the related asset group.

(1) During the year ended December 31, 2023, we amended our existing office space lease for our corporate headquarters in 
Seattle, Washington, to provide the landlord the option to terminate a portion of our lease prior to the original lease 
termination date. In December 2023, the landlord exercised the early termination option for the relevant floors effective June 
30, 2024. This modification to the lease term resulted in an immediate reduction in the right of use asset and lease liability of 
$8 million. We ceased use of the terminated space as of December 31, 2023, and as a result, we accelerated recognition of $14 
million of amortization for the related right of use asset during the year ended December 31, 2023.

(2) During the year ended December 31, 2021, we amended our existing office space lease for our corporate headquarters in 
Seattle, Washington, whereby the renewal options for certain existing office space which we had previously included in the 
measurement of the lease liability and right of use asset were removed and we partially terminated our lease early for certain 
existing office space, resulting in a reduction of the related lease liability and right of use asset of approximately $44 million 
and $42 million, respectively. The lease term for certain other existing leased office space in Seattle was extended such that it 
now expires in 2032 and retains the two five-year renewal options, partially offsetting the reduction of the lease liability and 
right of use asset described above.

We utilize master repurchase agreements to provide capital for Zillow Home Loans. The master repurchase agreements 

provide short-term financing between the issuance of a mortgage loan and when Zillow Home Loans sells the loan to an 
investor or directly to an agency. The carrying amounts of our master repurchase agreements approximate their fair values 
because of their short-term nature. The following table summarizes certain details related to our master repurchase agreements

On May 25, 2023, the Zillow Home Loans’ master repurchase agreement with Credit Suisse AG, Cayman Islands was 

reassigned to Atlas Securitized Products, L.P. (“Atlas”). No other material changes were made to the master repurchase 
agreement in connection with the reassignment. 

On June 1, 2023, Zillow Home Loans entered into a master repurchase agreement with JPMorgan Chase Bank, N.A. 
(“JPMC”). The master repurchase agreement provides a total maximum borrowing capacity of $100 million, $25 million of 
which is committed, until May 30, 2024.(cid:3)

On October 11, 2023, Zillow Home Loans entered into a master repurchase agreement with UBS AG. The master 

repurchase agreement provides a total maximum borrowing capacity of $100 million through October 9, 2024. 

In accordance with the master repurchase agreements, Atlas, JPMC, UBS AG, and prior to its expiration in June 2023, 

Citibank, N.A. (together the “Lenders”), have agreed to pay Zillow Home Loans a negotiated purchase price for eligible loans, 
and Zillow Home Loans has 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 December 31, 2023 and 2022, $99 million and $28 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 Secured Overnight Financing 
Rate plus an applicable margin, as defined by the governing agreements. Borrowings on the warehouse line of credit, prior to its 
termination on November 28, 2023, bore interest at a floating rate based on Bloomberg Short-Term Yield Index Rate plus an 
applicable margin, as defined by the governing agreement. The master repurchase agreements include customary 
representations and warranties, covenants and provisions regarding events of default. As of December 31, 2023, Zillow Home 
Loans was in compliance with all financial covenants and no event of default had occurred. The repurchase agreements are 
recourse to Zillow Home Loans, and have no recourse to Zillow Group or any of its other subsidiaries.(cid:3)

Convertible Senior Notes 

Prior to the adoption of new accounting guidance on January 1, 2022, we accounted for the issuance of convertible senior 
notes by separating them into their liability and equity components. The carrying amount of the liability component for each of 
the convertible senior notes was calculated by measuring the fair value of a similar liability that does not have an associated 
convertible feature. The carrying amount of the equity component, representing the conversion option, was determined by 
deducting the fair value of the liability component from the par value of the convertible senior notes. The difference between 
the principal amounts and the liability components represented the respective debt discounts, which were recorded as a direct 
deduction from the related debt liability in the consolidated balance sheets and amortized to interest expense using the effective 
interest method over the term of the convertible senior notes. The equity components of the convertible senior notes, net of 
issuance costs, were included in additional paid-in capital in the consolidated balance sheets and were not remeasured as long 
as they continued to meet the conditions for equity classification. Upon adoption of the new accounting guidance, we de-
recognized the equity components of the convertible senior notes and the respective debt discounts through a decrease to 
additional paid-in capital, an increase to long-term debt and a cumulative-effect adjustment to accumulated deficit of 
$156 million.(cid:3)

The convertible notes maturing in 2026 (“2026 Notes”), 2025 (“2025 Notes”) and 2024 (“2024 Notes”) (together, 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 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 convertible senior notes is classified as Level 
2 and was determined through consideration of quoted market prices in markets that are not active.

Prior to the close of business on the business day immediately preceding the applicable Early Conversion Date, the Notes 
will be convertible at the option of the holders only under certain conditions. On or after the applicable Early Conversion Date, 
until the close of business on the second scheduled trading day immediately preceding the applicable Maturity Date, holders 
may convert the Notes at their option at the applicable Conversion Rate then in effect, irrespective of these conditions. We will 
settle conversions of the Notes by paying or delivering, as the case may be, cash, shares of Class C capital stock, or a 
combination of cash and shares of Class C capital stock, at its election. The applicable Conversion Rate for each series of Notes 
will initially be the conversion rate of shares of Class C capital stock per $1,000 principal amount of the Notes (equivalent to an 
initial Conversion Price per share of Class C capital stock). The applicable Conversion Rate and the corresponding initial 
Conversion Price will be subject to adjustment in some events but will not be adjusted for any accrued and unpaid interest. We 
may redeem for cash all or part of the respective series of Notes, at our option, on or after the applicable Optional Redemption 
Date, under certain circumstances, at a redemption price equal to 100% of the principal amount of the Notes to be redeemed, 
plus accrued and unpaid interest to, but excluding, the redemption date (as defined in the indentures governing the Notes). We 
may not redeem a series of Notes prior to the applicable Optional Redemption Date. We may redeem for cash all or any portion

of a series of Notes, at our option, in whole or in part on or after the applicable Optional Redemption Date if the last reported 
sale price per share of our Class C capital stock has been at least 130% of the Conversion Price then in effect for at least 20 
trading days (whether or not consecutive) during any 30 consecutive trading day period. The conversion option does not meet 
the criteria for separate accounting as a derivative as it is indexed to our own stock. 

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 December 31, 2023. Accordingly, each series 
of the Notes is not redeemable or convertible at the option of the holders during the three months ending March 31, 2024.  

If the we undergo a fundamental change (as defined in the indentures governing the Notes), holders may require us to 
repurchase for cash all or part of a series of Notes, as applicable, at a repurchase price equal to 100% of the principal amount of 
the notes to be purchased, plus accrued and unpaid interest to, but excluding, the fundamental change repurchase date (as 
defined in the indentures governing the Notes). In addition, if certain fundamental changes occur, we may be required, in 
certain circumstances, to increase the conversion rate for any of the Notes converted in connection with such fundamental 
changes by a specified number of shares of our Class C capital stock. Certain events are also considered “Events of Default,” 
which may result in the acceleration of the maturity of the Notes, as described in the indentures governing the Notes. There are 
no financial covenants associated with the Notes. 

During the year ended December 31, 2023 and in accordance with our repurchase authorizations, we repurchased 
$58 million aggregate principal amount of the 2025 Notes through open market transactions for $57 million in cash, including 
accrued interest, resulting in a gain on extinguishment of debt of $1 million recognized in our consolidated statements of 
operations. For additional information on the repurchase authorizations, see Note 13 under the subsection titled “Share 
Repurchase Authorizations.” There were no conversions or repurchases of convertible senior notes during the year ended 
December 31, 2022. The following table summarizes the activity for our convertible senior notes for the period presented (in

(1) For convertible senior notes converted by note holders, the total fair value of consideration transferred includes the value of shares 
transferred to note holders using the daily volume weighted-average price of our Class C capital stock on the conversion date and an 
immaterial amount of cash paid in lieu of fractional shares. For convertible senior notes redeemed, the total fair value of consideration 
transferred comprises cash transferred to note holders to settle the related notes. 

(2) Consideration allocated to the liability component is based on the fair value of the liability component immediately prior to settlement, 
which was calculated using a discounted cash flow analysis with a market interest rate of a similar liability that does not have an associated 
convertible feature.

The capped call confirmations are expected generally to reduce the potential dilution of our Class C capital stock in 
connection with any conversion of the Notes and/or offset the cash payments the Company is required to make in excess of the 
principal amount of such notes in the event that the market price of the Class C capital stock is greater than the strike price of 
the capped call confirmations (which initially corresponds to the initial Conversion Price of such notes and is subject to certain 
adjustments under the terms of the capped call confirmations), with such reduction and/or offset subject to a cap based on the 
cap price of the capped call confirmations. The capped call confirmations with respect to the 2026 Notes and the 2024 Notes 
have an Initial Cap Price per share, which represents a premium (“Cap Price Premium”) over the relevant historical closing 
price of the Company’s Class C capital stock on the Nasdaq Global Select Market, and is subject to certain adjustments under 
the terms of the capped call confirmations. The capped call confirmations will cover, subject to anti-dilution adjustments 
substantially similar to those applicable to the convertible senior notes, the number of shares of Class C capital stock that will 
underlie such notes. The capped call confirmations do not meet the criteria for separate accounting as a derivative as they are 
indexed to our own stock. The capped call premiums paid have been included as a net reduction to additional paid-in capital 
within shareholders’ equity.  

Note 12. Income Taxes 

We are subject to income taxes in the United States (federal and state) and certain foreign jurisdictions. We recorded 
income tax expense of $4 million and $3 million for the years ended December 31, 2023 and December 31, 2022, respectively, 
primarily due to state taxes. We recorded an income tax benefit of $1 million for the year ended December 31, 2021, comprised 
of a $3 million income tax benefit from a decrease in the valuation allowance associated with our September 2021 acquisition 
of ShowingTime, partially offset by $2 million of tax expense primarily due to state income taxes.

Realization of deferred tax assets is dependent upon the generation of future taxable income, if any, the timing and 
amount of which are uncertain. We have provided a full valuation allowance against the net deferred tax assets as of December 
31, 2023 and 2022 because, based on the weight of available evidence, it is more likely than not (a likelihood of more than 
50%) that some or all of the deferred tax assets will not be realized. The valuation allowance increased by $22 million and

$97 million during the years ended December 31, 2023 and 2022, respectively. 

We have accumulated federal net operating losses of approximately $1.4 billion and $1.8 billion, as of December 31, 
2023 and 2022, respectively, which are available to reduce future taxable income. We have accumulated state net operating 
losses of approximately $56 million and $63 million (tax effected) as of December 31, 2023 and 2022, respectively. Federal net 
operating losses generated in taxable periods on or before December 31, 2017 have a twenty-year carryforward period and 
begin to expire in 2036. Federal net operating loss carryforwards generated in taxable years beginning after December 31, 2017 
may be carried forward indefinitely, but the deductibility of such net operating loss carryforwards in taxable years beginning 
after December 31, 2020 is limited to 80% of taxable income. State net operating loss carryforward periods for the various state 
jurisdictions generally range from three years to indefinite-lived and begin to expire in 2024. Additionally, we have net research 
and development credit carryforwards of $166 million and $164 million as of December 31, 2023 and 2022, respectively, which 
are available to reduce future tax liabilities. The research and development credit carryforwards begin to expire in 2025. Under 
Sections 382 and 383 of the Internal Revenue Code, if a corporation undergoes an “ownership change”, the corporation’s ability 
to use its pre-change net operating loss carryforwards and other pre-change tax attributes, such as research and development 
credits, to offset its post-change taxable income or income tax liability may be limited. In connection with our August 2013 
public offering of our Class A common stock, we experienced an ownership change that triggered Sections 382 and 383, which 
may limit our ability to utilize our net operating loss and research and development credit carryforwards. In connection with our 
February 2015 acquisition of Trulia, Trulia experienced an ownership change that triggered Section 382 and 383, which may 
limit Zillow Group’s ability to utilize Trulia’s net operating loss and research and development credit carryforwards. 

Our primary income tax jurisdiction is the United States (federal). With limited exceptions for state taxing authorities, 

which are not material to the financial statements, all tax years for which we have filed a tax return remain subject to 
examination due to the existence of net operating loss carryforwards.

At December 31, 2023, the total amount of unrecognized tax benefits of $95 million is recorded as a reduction to our 

deferred tax asset when available. We do not anticipate that the amount of existing unrecognized tax benefits will significantly 
increase or decrease within the next 12 months. Accrued interest and penalties related to unrecognized tax benefits are recorded 
as income tax expense and are not material. 

Note 13. Shareholders’ Equity 

Preferred Stock 

The Board has the authority to fix and determine and to amend the number of shares of any series of preferred stock that 
is wholly unissued or to be established and to fix and determine and to amend the designation, preferences, voting powers and 

106 

 
 
 
 
 
 
 
 
 
 
limitations and the relative, participating, optional or other rights, of any series of shares of preferred stock that is wholly 
unissued or to be established, subject in each case to certain approval rights of holders of our outstanding Class B common 
stock. There was no preferred stock issued and outstanding as of December 31, 2023 or December 31, 2022. 

Common and Capital Stock 

Our Class A common stock has no preferences or privileges and is not redeemable. Holders of Class A common stock are 

entitled to one vote for each share. 

Our Class B common stock has no preferences or privileges and is not redeemable. At any time after the date of issuance, 
each share of Class B common stock, at the option of the holder, may be converted into one share of Class A common stock, or 
automatically converted into Class A common stock upon the affirmative vote by or written consent of holders of a majority of 
the shares of the Class B common stock. During the years ended December 31, 2023, 2022 and 2021, no shares of Class B 
common stock were converted into Class A common stock at the option of the holders. Holders of Class B common stock are 
entitled to 10 votes for each share. 

Our Class C capital stock has no preferences or privileges, is not redeemable and, except in limited circumstances, is non-

voting. 

Equity Distribution Agreement 

On February 17, 2021, we entered into an equity distribution agreement with certain sales agents and/or principals (the 
“Managers”), pursuant to which we may offer and sell from time to time, through the Managers, shares of our Class C capital 
stock, having an aggregate gross sales price of up to $1.0 billion, in such share amounts as we may specify by notice to the 
Managers, in accordance with the terms and conditions set forth in the equity distribution agreement. 

There were no shares issued under the equity distribution agreement during the years ended December 31, 2023 and 

December 31, 2022. 

Share Repurchase Authorizations 

Prior to the year ended December 31, 2023, the Board authorized the repurchase of up to $1.8 billion of our Class A 
common stock, Class C capital stock, outstanding convertible senior notes or a combination thereof. On July 31, 2023, the 
Board authorized the repurchase of up to an additional $750 million of our Class A common stock, Class C capital stock, 
outstanding convertible senior notes or a combination thereof. This additional authorization (together with the previous 
authorizations, the “Repurchase Authorizations”) increased our total cumulative Repurchase Authorizations to $2.5 billion. 

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 December 31, 2023, $770 million 
remained available for future repurchases pursuant to the Repurchase Authorizations. 

The following table summarizes our Class A common stock and Class C capital stock repurchase activity under the 
Repurchase Authorizations for the periods presented (in millions, except share data which are presented in thousands, and per

Note 14. Share-Based Awards 

Zillow Group, Inc. 2020 Incentive Plan(cid:3)

On June 9, 2020, the Zillow Group, Inc. 2020 Incentive Plan (the “2020 Plan”) became effective, which replaces the 

Zillow Group, Inc. Amended and Restated 2011 Incentive Plan (the “2011 Plan”), which became effective July 19, 2011. 
Subject to adjustment from time to time as provided in the 2020 Plan, a total of 12 million shares of Class C capital stock are 
authorized for issuance under the 2020 Plan. In addition, shares previously available for new grants under the 2011 Plan as of 
June 9, 2020 and shares subject to outstanding awards under the 2011 Plan as of June 9, 2020 that on or after that date cease to 
be subject to such awards (other than by reason of exercise or settlement of the awards in vested or nonforfeitable shares) are 
also available for issuance under the 2020 Plan. The number of shares authorized under the 2020 Plan will be increased on the 
first day of each calendar year, beginning January 1, 2021 and ending on and including January 1, 2030, by an amount equal to 
the lesser of (a) 5% of our outstanding Class A common stock, Class B common stock and Class C capital stock on a fully 
diluted basis as of the end of the immediately preceding calendar year and (b) a number of shares determined by our Board. 
Shares issued under the 2020 plan may be issued from authorized and unissued shares of Class C capital stock. The 2020 Plan 
is administered by the Compensation Committee of the Board (the “Compensation Committee”). Under the terms of the 2020 
Plan, the Compensation Committee may grant equity awards, including incentive or nonqualified stock options, restricted stock, 
restricted stock units, restricted units, stock appreciation rights, performance shares or performance units to employees, 
directors and consultants of Zillow Group and its subsidiaries. The Board has also authorized certain senior executive officers 
to grant equity awards under the 2020 Plan, within limits prescribed by our Board. 

Options under the 2020 Plan are granted with an exercise price per share not less than 100% of the fair market value of 

our Class C capital stock on the grant date, with the exception of substituted option awards granted in connection with 
acquisitions, and are exercisable at such times and under such conditions as determined by the Compensation Committee. Any 
portion of an option that is not vested and exercisable on the date of a participant’s termination of service expires on such date. 
Employees generally forfeit their rights to exercise vested options three months following their termination of employment or 
12 months following termination by reason of death, disability or retirement. Options granted under the 2020 Plan expire no 
later than ten years from the grant date and typically vest over a period of four years. 

Restricted stock units granted under the 2020 Plan typically vest over a period of four years. Generally, any portion of a 

restricted stock unit that is not vested on the date of a participant’s termination of service expires on such date. 

In addition to the option awards and restricted stock units typically granted under the Zillow Group, Inc. 2020 Incentive 
Plan (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.  

Zillow Group, Inc. Amended and Restated 2011 Incentive Plan 

Options and restricted stock units that remain outstanding under the 2011 Plan have vesting and exercisability terms 

consistent with those described above for awards granted under the 2020 Plan.

Zillow Group, Inc. 2019 Equity Inducement Plan 

On August 8, 2019, the 2019 Equity Inducement Plan (“Inducement Plan”) became effective. Subject to adjustment from 
time to time as provided in the Inducement Plan, 10 million shares of Class C capital stock are available for issuance under the 
Inducement Plan. Shares issued under the Inducement Plan shall be drawn from authorized and unissued shares of Class C 
capital stock. The purpose of the Inducement Plan is to attract, retain and motivate certain new employees of the Company and 
its subsidiaries by providing them the opportunity to acquire a proprietary interest in the Company and to align their interests 
and efforts to the long-term interests of the Company’s shareholders. Each award under the Inducement Plan is intended to 
qualify as an employment inducement award pursuant to Listing Rule 5635(c) of the corporate governance rules of the 
NASDAQ Stock Market. The Inducement Plan is administered by the Compensation Committee. Under the terms of the 
Inducement Plan, the Compensation Committee may grant equity awards, including nonqualified stock options, restricted stock 
or restricted stock units or restricted units to new employees of the Company and its subsidiaries.  

Options under the Inducement Plan are granted with an exercise price per share not less than 100% of the fair market 

value of our Class C capital stock on the date of grant, with the exception of substituted option awards granted in connection 
with acquisitions, and are exercisable at such times and under such conditions as determined by the Compensation Committee. 
Any portion of an option that is not vested and exercisable on the date of a participant’s termination of service generally expires 
on such date. Employees generally forfeit their rights to exercise vested options three months following their termination of 
employment or 12 months following termination by reason of death, disability or retirement. Options granted under the 
Inducement Plan expire no later than ten years from the grant date and typically vest over a period of four years. 

Restricted stock units granted under the Inducement Plan typically vest over a period of four years. In general, any 

portion of a restricted stock unit that is not vested on the date of a participant’s termination of service expires on such date. 

Option Award Repricing 

On August 3, 2022, upon recommendation of the Compensation Committee, the Board approved adjustments to the 

exercise price of certain outstanding vested and unvested option awards for eligible employees. The exercise price of eligible 
option awards was reduced to $38.78, which was the closing market price of our Class C capital stock on August 8, 2022. No 
other changes were made to the terms and conditions of the eligible option awards. We have accounted for the reprice of the 
eligible option awards as an equity modification whereby the incremental fair value attributable to the repriced option awards, 
as measured on the date of reprice, will be recognized as additional share-based compensation expense. The reprice impacted 
7 million stock option awards, affected 3,348 employees and was expected to result in incremental share-based compensation 
expense of $66 million in total over the remaining requisite service period of the original awards. The weighted-average total 
fair value of options repriced in August 2022 was $67.58.(cid:3)

Basic net loss per share and basic income (loss) from continuing operations per share are computed by dividing net loss 

or income (loss) from continuing operations, as applicable, by the weighted-average number of shares (including Class A 
common stock, Class B common stock and Class C capital stock) outstanding during the period. In the calculation of basic net 
loss per share and basic income (loss) from continuing operations per share, undistributed earnings are allocated assuming all 
earnings during the period were distributed. 

Diluted net loss per share and diluted net income (loss) from continuing operations per share is computed by dividing net 
loss or net income (loss) from continuing operations, as applicable, by the weighted-average number of shares (including Class 
A common stock, Class B common stock and Class C capital stock) outstanding during the period, which is calculated based on 
net income (loss) from continuing operations, and potentially dilutive Class C capital stock equivalents, except in cases where 
the effect of the Class C capital stock equivalent would be antidilutive. Potentially dilutive Class C capital stock equivalents 
consist of stock issuable upon exercise of stock options, stock underlying unvested restricted stock units, and stock issuable 
upon conversion of outstanding convertible senior notes. 

Class C capital stock issuable upon exercise of stock options and Class C capital stock underlying unvested restricted 

stock units are calculated using the treasury stock method. 

We have applied the if-converted method for calculating any potential dilutive effect of the conversion of the outstanding 
convertible notes on diluted net loss per share and diluted net income (loss) from continuing operations per share, if applicable. 
The following table presents the maximum number of shares and conversion price per share of Class C capital stock for each of 
the Notes based on the aggregate principal amount outstanding as of December 31, 2023 (in thousands, except per share

In the event of liquidation, dissolution, distribution of assets or winding-up of the Company, the holders of all classes of 
common and capital stock have equal rights to receive all the assets of the Company after the rights of the holders of preferred 
stock have been satisfied. We have not presented net loss per share under the two-class method for our Class A common stock, 
Class B common stock and Class C capital stock because it would be the same for each class due to equal dividend and 
liquidation rights for each class. 

Note 16. Commitments and Contingencies 

Interest Rate Lock Commitments 

We have entered into IRLCs with prospective borrowers under our mortgage origination business whereby we commit to 
lend a certain loan amount under specific terms and at a specific interest rate to the borrower. These commitments are treated as 
derivatives and are carried at fair value. For additional information regarding our IRLCs, see Note 4 to our consolidated 
financial statements. 

Lease Commitments 

We have entered into various non-cancelable operating lease agreements for certain of our office space and equipment 
with original lease periods expiring between 2024 and 2032. For additional information regarding our lease agreements, see 
Note 10 to our consolidated financial statements. 

Purchase Commitments 

Purchase commitments primarily include various non-cancelable agreements to purchase content related to our mobile 

applications and websites and certain cloud computing services. The amounts due for non-cancelable purchase commitments as 
of December 31, 2023 are as follows (in millions):

In conducting our title and escrow operations, we routinely hold customers’ assets in escrow, pending completion of real 
estate transactions, and are responsible for the proper disposition of these balances for our customers. Certain of these amounts 
are maintained in segregated bank accounts and have not been included in the accompanying consolidated balance sheets. 
These balances were not material as of December 31, 2023 and 2022. 

Letters of Credit 

As of December 31, 2023 and 2022, we have outstanding letters of credit of approximately $11 million and $16 million, 

respectively, which secure our lease obligations in connection with certain of our office space operating leases. 

Surety Bonds 

In the course of business, we are required to provide financial commitments in the form of surety bonds to third parties as 

a guarantee of our performance on and our compliance with certain obligations. If we were to fail to perform or comply with 
these obligations, any draws upon surety bonds issued on our behalf would then trigger our payment obligation to the surety 
bond issuer. We have outstanding surety bonds issued for our benefit of approximately $15 million and $13 million as of 
December 31, 2023 and 2022, respectively. 

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 December 31, 2023 
or 2022. 

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 

113 

 
 
 
 
 
 
 
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. 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.(cid:3)

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 the one 
remaining patent, for which this case continues to remain stayed. 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. 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 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. We intend to deny the allegations of wrongdoing and intend to 

114 

 
 
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, including, but 
not limited to, losses arising out of the breach of such agreements and out of intellectual property infringement claims made by 
third parties. In addition, we have agreements that indemnify certain issuers of surety bonds against losses that they may incur 
as a result of executing surety bonds on our behalf. For our indemnification arrangements, payment may be conditional on the 
other party making a claim pursuant to the procedures specified in the particular contract. Further, our obligations under these 
agreements may be limited in terms of time and/or amount, and in some instances, we may have recourse against third parties 
for certain payments. In addition, we have indemnification agreements with certain of our directors and executive officers that 
require us, among other things, to indemnify them against certain liabilities that may arise by reason of their status or service as 
directors or officers. The terms of such obligations may vary. 

Note 17. Employee Benefit Plan 

We have a defined contribution 401(k) retirement plan covering Zillow Group employees who have met certain eligibility 

requirements (the “Zillow Group 401(k) Plan”). Eligible employees may contribute pre-tax compensation up to a maximum 
amount allowable under the Internal Revenue Service limitations. Employee contributions and earnings thereon vest 
immediately. We currently match up to 4% of employee contributions under the Zillow Group 401(k) Plan. The total expense 
related to the Zillow Group 401(k) Plan was $33 million, $29 million and $27 million, respectively, for the years ended 
December 31, 2023, 2022 and 2021. 

Note 18. Revenue and Contract Balances 

We recognize revenue when or as we satisfy our performance obligations by transferring control of the promised products 
or services to our customers in an amount that reflects the consideration to which we expect to be entitled in exchange for those 
products or services. See Note 2 for additional information regarding our revenue recognition accounting policies.

Beginning in 2023, our chief executive officer, who acts as the chief operating decision maker, began to manage our 
business, make operating decisions and evaluate operating performance on the basis of the company as a whole, instead of on a 
segment basis as he did prior to 2023. Accordingly, this change resulted in revisions to the nature and substance of information 
regularly provided to and used by the chief operating decision maker. This serves to align our reported results with our ongoing 
growth strategy and our intent to provide integrated customer solutions for all tasks and services related to facilitating real 
estate transactions. As a result, we have determined that we have a single reportable segment. In addition, our revenue is 
classified into four categories: Residential, Rentals, Mortgages and Other. Certain prior period amounts have been revised to 
reflect these changes.  

The Residential revenue category primarily includes revenue for our Premier Agent and new construction marketplaces, 
as well as revenue from the sale of other advertising and business technology solutions for real estate professionals, including 
StreetEasy for-sale product offerings, ShowingTime+ and Follow Up Boss. Our Rentals and Mortgages revenue categories 
remain consistent with our historical presentation, and our Other revenue category primarily includes revenue generated from 
display advertising.

Item 9. Changes in and Disagreements with Accountants on Accounting and Financial Disclosure. 

None. 

Item 9A. Controls and Procedures. 

Evaluation of Disclosure Controls and Procedures 

The Company carried out an evaluation, with the participation of our management, and under the supervision of our 
Chief Executive Officer and Chief Financial Officer, of the effectiveness of our disclosure controls and procedures (as defined 
under Rule 13a-15(e) and Rule 15d-15(e) under the Securities Exchange Act of 1934, as amended (the “Exchange Act”)) as of 
the end of the period covered by this report. Based upon that evaluation, our Chief Executive Officer and Chief Financial 
Officer concluded that our disclosure controls and procedures were effective as of December 31, 2023. 

Management’s Report on Internal Control Over Financial Reporting 

Our management is responsible for establishing and maintaining adequate internal control over financial reporting, as 
such term is defined under Rule 13a-15(f) under the Exchange Act. Under the supervision and with the participation of our 

116 

 
 
  
 
 
 
 
 
 
management, including our Chief Executive Officer and Chief Financial Officer, we conducted an evaluation of the 
effectiveness of our internal control over financial reporting based on the framework in Internal Control – Integrated 
Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (2013 framework). Based on 
our evaluation, our management concluded that our internal control over financial reporting was effective as of December 31, 
2023. 

We intend to regularly review and evaluate the design and effectiveness of our disclosure controls and procedures and 
internal control over financial reporting on an ongoing basis and to improve these controls and procedures over time and to 
correct any deficiencies that we may discover in the future. While we believe the present design of our disclosure controls and 
procedures and internal control over financial reporting are effective, future events affecting our business may cause us to 
modify our controls and procedures. 

The Company’s independent registered public accounting firm has issued an attestation report regarding its assessment of 

the effectiveness of the Company’s internal control over financial reporting as of December 31, 2023. 

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 Exchange Act that occurred during the three months ended December 31, 2023 
that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM  

To the shareholders and the Board of Directors of Zillow Group, Inc. 

Opinion on Internal Control over Financial Reporting 

We have audited the internal control over financial reporting of Zillow Group, Inc. (the “Company”) as of December 31, 2023,  
based on criteria established in Internal Control — Integrated Framework (2013) issued by the Committee of Sponsoring 
Organizations of the Treadway Commission (COSO). In our opinion, the Company maintained, in all material respects, 
effective internal control over financial reporting as of December 31, 2023, based on criteria established in Internal Control — 
Integrated Framework (2013) issued by COSO. 

We have also audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States) 
(PCAOB), the consolidated financial statements as of and for the year ended December 31, 2023, of the Company and our 
report dated February 14, 2024, expressed an unqualified opinion on those financial statements. 

Basis for Opinion 

The Company’s management is responsible for maintaining effective internal control over financial reporting and for its 
assessment of the effectiveness of internal control over financial reporting, included in the accompanying Management’s Report 
on Internal Control over Financial Reporting. Our responsibility is to express an opinion on the Company’s internal control over 
financial reporting based on our audit. We are a public accounting firm registered with the PCAOB and are required to be 
independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and 
regulations of the Securities and Exchange Commission and the PCAOB. 

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

Definition and Limitations of Internal Control over Financial Reporting 

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

Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, 
projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate 
because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.

Section 21E of the Securities Exchange Act of 1934 that involve risks and uncertainties, including, without limitation, statements 
regarding our future targets, the future performance and operation of our business, our business strategies and ability to 
translate such strategies into financial performance, the current and future health and stability of the residential housing market 
and economy, volatility of mortgage interest rates, and our expectations regarding future shifts in behavior by consumers and 
employees. Statements containing words such as “may,” “believe,” “anticipate,” “aim,” “expect,” “intend,” “plan,” “project,” 
“predict,” “will,” “projections,” “continue,” “estimate,” “outlook,” “opportunity,” “guidance,” “would,” “could,” “strive,”

on information currently available to management, and although we believe the expectations reflected in the forward-looking 
statements are reasonable, we cannot guarantee these results. Differences in Zillow Group’s actual results from those described 
in these forward-looking statements may result from actions taken by us as well as from risks and uncertainties beyond our 
control. For more information about potential factors that could affect Zillow Group’s business and financial results, please
