the shares of common stock on December 12, 2014 as reported by the NASDAQ Global Select Market on such date was approximately $409.7 million. The Registrant has elected to use December 12, 2014, which was the initial trading date on the
NASDAQ Global Select Market, as the calculation date because on June 30, 2014 (the last business day of the registrants most recently completed second fiscal quarter), the registrant was a privately held company. Shares of the
registrants common stock held by each executive officer, director and holder of 10% or more of the outstanding common stock have been excluded in that such persons may be deemed to be affiliates. This calculation does not reflect a
determination that certain persons are affiliates of the registrant for any other purpose.

The number of shares of Registrants Common Stock
outstanding as of March 20, 2015 was 43,118,928.

Portions of the Registrants Definitive Proxy Statement relating to the
Registrants 2015 Annual Meeting of Shareholders, which will be filed with the Securities and Exchange Commission within 120 days after the end of the Registrants fiscal year ended December 31, 2014, are incorporated by reference
into Part III of this Annual Report on Form 10-K where indicated.

PART I

Item 1. Business.

Company Overview

Hortonworks is the leading contributor to and provider of Apache Hadoop® for
the enterprise, and our mission is to establish Hadoop as the foundational technology of the modern enterprise data architecture. Our solution, the Hortonworks Data Platform, or HDP, is an enterprise-grade data management platform that enables a
centralized architecture for running batch, interactive and real-time applications simultaneously across shared datasets. HDP is built on Hadoop and supported by a comprehensive set of capabilities that address the core requirements of security,
operations and data governance.

We seek to advance the market adoption of Hadoop and provide enterprises with a new data management
solution that enables them to harness the power of big data to transform their businesses through more effective and efficient management of their valuable data assets. A Hadoop cluster combines commodity servers with local storage and an open
source software distribution to create a reliable distributed compute and storage platform for large data sets scalable up to petabytes, or PBs, with thousands of servers or nodes.

Our solution is an enterprise-grade data management platform built on a unique distribution of Apache Hadoop and powered by YARN, the next
generation computing and resource management framework. We continuously drive innovation in the Apache community with a mission to further Hadoops development for enterprises of all types and sizes. Our platform deeply integrates with key data
center technologies to enable best-of-breed data architectures and enables our customers to collect, store, process and analyze increasing amounts of existing and new data types in a way that augments rather than replaces their existing data center
infrastructure.

We employ a differentiated approach in that we are committed to serving the Apache Software Foundation open source
ecosystem and to sharing all of our product developments with the open source community. We lead the community for open source Hadoop and employ a large number of core committers to the various Enterprise Grade Hadoop projects. We believe that
keeping our business model free from architecture design conflicts that could limit the ultimate success of our customers in leveraging the benefits of Hadoop at scale is a significant competitive advantage.

We are recognized as a leader in Hadoop based on the strengths of our current offering and our strategy, and we have invested to enhance our
position through the introduction of our Enterprise Grade Hadoop platform. Our Enterprise Grade Hadoop platform addresses modern data requirements and enables enterprises to significantly increase their data under management and their business
productivity with this data.

We were founded in 2011 when our senior management team, led by our Chief Executive Officer Rob Bearden,
partnered with a core team of Hadoop developers and engineers from Yahoo! with a goal of expanding upon the early technology developed by Yahoo! in Hadoop, the initial rights to which we obtained from Yahoo!. During 2012 we launched our Enterprise
Grade Hadoop platform, the Hortonworks Data Platform, or HDP, for which we provide support subscriptions and professional services.

Consistent with our open source approach, we generally make HDP available free of charge and derive the predominant amount of our revenue from
customer fees from support subscription offerings and professional services. Our subscription business model delivers customer value throughout the entire lifecycle: from development and proof-of-concept, to quality assurance and testing, to
production and deployment. A subscription generally entitles a customer to, among other things, a specified level of support, as well as new versions of the software, access to upgrades, updates and patches, remote troubleshooting, advanced
knowledge base, diagnosis of installation and configuration issues, diagnosis of cluster management and performance issues, application development advice, and compatibility with an ecosystem of certified hardware and software applications.

with Hewlett-Packard Company, Hitachi Data Systems, Microsoft Corporation, Pivotal Software, Rackspace Hosting, Inc., Red Hat, Inc., SAP AG, Teradata Corporation and Yahoo! Inc. focused on tightly integrated development, marketing and support
strategies to maximize the success of our solutions.

Industry Background

Major technology innovations such as social media, mobile and cloud computing, new web-based applications, such as SaaS and the Internet of
Things, in which devices with sensors and actuators transmit increasing amounts of data automatically, have created an always-on, constantly connected society that is putting increasing pressure on enterprise data center infrastructure. Enterprises
are facing rapidly escalating costs and complexity associated with adjusting to these new realities and managing the resulting data proliferation in their data centers. Enterprises are struggling to manage these pressures efficiently while seeking
to enable more proactive and interactive business applications that harness and leverage the power of big data.

Enterprises are not only
inundated with increasing amounts of data but also struggle with managing more types of data that are less easily managed by traditional data center architectures. Historically, enterprises focused primarily on managing data from dedicated and
disparate data center systems, including enterprise resource planning, or ERP, and customer relationship management, or CRM, systems. To store and process these types of data, enterprises were able to utilize relational database management systems
optimized for analyzing preselected, structured data stored within isolated silos.

The increasing variety of data, including new
unstructured data types such as clickstream data, geo-location data, sensor and machine data, sentiment data, server log data and other data generated by emails, documents and other file types, is fueling the exponential growth in the aggregate
amount of data that has the potential to be captured and managed by the enterprise to drive business value. The higher volume, velocity and variety of context-rich data have historically not been captured, managed or analyzed by the enterprise.

As a result of the limitations of traditional data center architectures, enterprises are seeking
new technologies to collect, store and access higher volumes, velocity and variety of data in a cost-effective manner, and to gain more actionable insight from their increasingly complex and growing data stores. Enterprises need to upgrade their
data center architectures to enable them to bring large volumes of data under management and to process and analyze multiple types of data in innovative ways.

Hadoop was originally developed in the early 2000s. Partnering with the Apache Hadoop community, Yahoo! led major innovations in the
technology to help tackle big data challenges and operate its business at scale. The traditional Hadoop (i.e., Hadoop Version 1.x) offering is largely a batch system that enables users to manage data at scale, but requires siloed computing clusters
by application with pre-selected data sets, thus limiting accessibility, interoperability and overall value. Incremental attempts to improve traditional Hadoop focused on bolting on data warehousing and analytics functionality as well as basic
levels of security and operations management, which were available through a mix of separate open source projects or commercially available software. This innovation demonstrated the early promise of Hadoop in enabling enterprises to address their
big data requirements, but traditional Hadoop still lacks the breadth of functionality and resiliency that would enable it to be deployed more broadly by enterprises in production use cases.

To improve on this early functionality, Hortonworks engineers created the initial architecture for YARN (Yet Another Resource
Negotiator) and developed the technology for it within the Apache Hadoop community, leading to the release of YARN in October 2013. This technology advancement transformed Hadoop (i.e., Hadoop Version 2.x) into a platform that allows for
multiple ways of interacting with data, including interactive SQL processing, real-time processing and online data processing, along with its traditional batch data processing. Several early vendors of traditional Hadoop have not made the transition
from the bolt on architecture of traditional Hadoop to fully embracing YARN in their respective offerings. YARN is a significant innovation in that it eliminates the need to silo data sets and reduces total cost of ownership by enabling a single
cluster to store a wide range of shared data sets on which mixed workloads spanning batch, interactive and real-time use cases can simultaneously process with predictable service levels. YARN is designed to serve as a common data operating system
that enables the Hadoop ecosystem to natively integrate applications and leverage existing technologies and skills while extending consistent security, governance and operations across the platform. With these capabilities, YARN can facilitate
mainstream Hadoop adoption by enterprises of all types and sizes for production use cases at scale.

Development

We embrace an open source software development model that uses the collective input, resources and knowledge of a global community of
contributors collaborating primarily within the Apache Software Foundation open source community on developing, maintaining and enhancing Apache Hadoop. We employ the largest number of active Apache Software Foundation committers, as defined by the
Apache Software Foundation, and Project Management Committee (PMC) members of any company for the Enterprise Grade Hadoop projects within the Hortonworks Data Platform, including Apache Hadoop, Apache Hive, Apache Pig, Apache Tez, Apache HBase,
Apache Accumulo, Apache Storm, Apache Ambari, Apache Ranger, Apache Knox, Apache Falcon, Apache Oozie, Apache Sqoop, Apache Flume and Apache Zookeeper. The number of active committers and active PMC members that are employed by us and focused on the
Apache Hadoop project individually as well in total across all of the Apache projects listed above is more than twice the total of the next largest employer of such committers. These employees enable us to drive innovation, define a roadmap for the
future of Hadoop, ensure predictable and reliable enterprise quality releases and provide comprehensive, enterprise-class support.

We
believe that we benefit from this open source development model because we are able to offer our software more quickly and with lower development cost than is typical of many software vendors who use a proprietary model to develop their products.
Our open source development model also benefits our support subscription customers and partners, who are able to take advantage of the quality and value of open source software that we help to define, develop, integrate, test, certify, deliver,
maintain, enhance and support. Our research and development expenses were $37.8 million for the year ended December 31, 2014, $14.6 million and $6.8 million for the eight months ended December 31, 2013 and 2012, respectively,

Competition

Within the
Enterprise Hadoop market, we compete against a variety of large software and infrastructure vendors, smaller specialized companies and custom development efforts. Our principal competitors in this market include pure play Hadoop distribution vendors
such as Cloudera and MapR Technologies, as well as enterprise software and infrastructure vendors that offer Hadoop distributions such as IBM Corporation and Oracle Corporation.

Within the broader big data market, an enterprise Hadoop solution may compete for workloads against traditional data warehouse solutions from
large vendors such as Teradata Corporation, Oracle Corporation, Microsoft Corporation, IBM Corporation, Hewlett-Packard Company, SAP and EMC Corporation, and non-relational NoSQL databases from pure play vendors such as MongoDB Inc. and DataStax,
Inc. Since enterprise Hadoop is commonly integrated with traditional data warehouses, such as our partnerships with Teradata and Hewlett-Packard Company, and NoSQL databases, such as our partnership with DataStax, this category of vendors and
solutions comprises a set of key partners who may compete with us in certain instances while partnering with us in others.

We believe the
principal competitive factors in the enterprise Hadoop and big data markets for our solution are:



| |  |  | name and reputation of the vendor or competitive offering;
| | - |  | ----------------------------------------------------------



| |  |  | ability to adapt development, sales, marketing and support to the open source software model;
| | - |  | ---------------------------------------------------------------------------------------------



| |  |  | product price, performance, scalability, reliability, functionality and ease of use;
| | - |  | ------------------------------------------------------------------------------------



| |  |  | value of support subscription offerings and quality of support and professional services;
| | - |  | -----------------------------------------------------------------------------------------



| |  |  | strategic alliances with major enterprise software and infrastructure providers;
| | - |  | --------------------------------------------------------------------------------



| |  |  | availability of third-party solutions that are integrated with and compatible with the technology;
| | - |  | --------------------------------------------------------------------------------------------------



| |  |  | number of Global 2000 reference accounts;
| | - |  | -----------------------------------------



| |  |  | ability to provide a credible and actionable roadmap for the technology;
| | - |  | ------------------------------------------------------------------------



| |  |  | ability to quickly diagnose software issues and provide patches and other solutions; and
| | - |  | ----------------------------------------------------------------------------------------



| |  |  | strength of the vendors relationships and reputation in the open source community.
| | - |  | -----------------------------------------------------------------------------------

We believe that we generally compete favorably on the basis of the foregoing factors. Since we employ a significant number of Hadoop core
committers and innovators, we are able to innovate the core open source technology, help define a roadmap for the future, provide predictable and reliable, enterprise-quality releases and offer comprehensive support to our support subscription
customers and deeply integrated solutions with our partners.

The traditional barriers to entry that are found in the proprietary software
model do not characterize the open source software model. For example, the financial and legal barriers to creating a new Hadoop distribution are

relatively low because the software components typically included in Hadoop distributions are publicly available under open source licenses that permit copying, modification and redistribution.
While anyone can use, copy, modify and redistribute the Hortonworks Data Platform, they are not permitted to refer to the product using the trademarked Hortonworks name unless they have a formal business relationship with us that allows
such references.

Some of our actual and potential competitors have advantages over us, such as longer operating histories, significantly
greater financial, technical, marketing or other resources, stronger brand and business user recognition, larger intellectual property portfolios and broader global distribution and presence. In addition, our industry is evolving rapidly and is
becoming increasingly competitive. Larger and more established companies may focus on operational intelligence and could directly compete with us. Smaller companies could also launch new products and services that we do not offer and that could gain
market acceptance quickly.

Intellectual Property

Our offerings, including the Hortonworks Data Platform and Hortonworks Sandbox, are built from software components licensed to the general
public under the Apache Software License and similar open source licenses. We obtain many components from software developed and released by contributors to independent open source software development projects primarily at the Apache Software
Foundation. Open source licenses grant licensees broad permissions to use, copy, modify and redistribute the Hortonworks Data Platform. As a result, open source development and licensing practices can limit the value of our software copyright
assets. Consequently, our trademarks may represent our most valuable intellectual property. As a result, we actively pursue registration of our trademarks, logos, service marks and domain names in the United States and in other countries. The
duration of our trademarks registered in the U.S. generally lasts as long as we use them in commerce and timely file all documents required by the United States Patent and Trademark Office to maintain such registrations.

We rely on a combination of trade secret, copyright and trademark laws, a variety of contractual arrangements, such as license agreements,
assignment agreements, confidentiality and non-disclosure agreements, and confidentiality procedures and technical measures to gain rights to and protect the intellectual property used in our business.

We also rely on certain intellectual property rights that we license from third parties, including under certain open source licenses. Though
such third-party technologies may not continue to be available to us on commercially reasonable terms, we believe that alternative technologies would be available to us.

Our policy is to require employees and independent contractors to sign agreements assigning to us any inventions, trade secrets, works of
authorship, developments and other processes generated by them on our behalf and agreeing to protect our confidential information, and all of our key employees and contractors have done so. We also control and monitor access to, and distribution of,
our proprietary information.

For a discussion of the risk factors relating to intellectual property that we believe could impact our
actual and expected results, see Risk Factors in this Annual Report on Form 10-K.

Item 1A. Risk Factors.

Investing in our common stock involves a high degree of risk. You should carefully consider the risks and uncertainties described below,
together with all of the other information in this report and in our other public filings, before making a decision to invest in our common stock. If any of the risks actually occur, our business, financial condition, results of operations and
prospects could be harmed. In that event, the trading price of our common stock could decline, and you could lose part or all of your investment.

Risks Related to Our Business

We have a history of losses, and we may not become profitable in the future.

We have incurred net losses in each year since our inception, including net losses of $177.4 million in the year ended December 31, 2014,
$46.2 million and $19.7 million in the eight months ended December 31, 2013 and 2012, $36.6 million and $11.5 million in the years ended April 30, 2013 and 2012. As a result, we had an accumulated deficit of $271.7 million at
December 31, 2014. These losses and our accumulated deficit includes the accounting for the Yahoo!, Inc., or Yahoo!, preferred stock warrant (the 2011 Yahoo! Warrant) described in Managements Discussion and Analysis of
Financial Condition and Results of Operations. Because the market for our solution is rapidly evolving and has not yet reached widespread adoption, it is difficult for us to predict our future results of operations. We may not achieve
sufficient revenue to attain and maintain profitability. We expect our operating expenses to increase over the next several years as we hire additional personnel, particularly in sales and marketing, expand and improve the effectiveness of our
distribution channels, and continue to invest in the development of the Hortonworks Data Platform. In addition, as we grow and as a result of being a newly public company, we will incur additional significant legal, accounting and other expenses
that we did not incur as a private company. As a result of these increased expenses, we will have to generate and sustain increased revenue to be profitable in future periods. Any failure by us to sustain or increase profitability on a consistent
basis could cause the value of our common stock to decline.

We have a limited operating history, which makes it difficult to
predict our future results of operations.

We were incorporated in 2011 and introduced our first solution in 2012. As a result of
our limited operating history, our ability to forecast our future results of operations is limited and subject to a number of uncertainties, including our ability to plan for and model future growth. Our historical revenue growth has been
inconsistent, has benefited from transactions with related parties and should not be considered indicative of our future performance. Further, in future periods, our revenue growth could slow or our revenues could decline for a number of reasons,
including slowing demand for our support subscription offerings and our professional services, increasing competition, a decrease in the growth of our overall market, or our failure, for any reason, to continue to capitalize on growth opportunities.
We have also encountered and will encounter risks and uncertainties frequently experienced by growing companies in rapidly changing industries, such as the risks and uncertainties described herein. If our assumptions regarding these risks and
uncertainties and our future revenue growth (each of which we use to plan our business) are incorrect or change, or if we do not address these risks successfully, our operating and financial results could differ materially from our expectations and
our business could suffer.

We do not have an adequate history with our support subscription offerings or pricing models to
accurately predict the long-term rate of support subscription customer renewals or adoption, or the impact these renewals and adoption will have on our revenues or results of operations.

We have limited experience with respect to determining the optimal prices for our support subscription offerings. As the market for open source
distributed data platforms matures, or as new competitors introduce new products or services that compete with ours, we may be unable to attract new support subscription customers at the same price or based on the same pricing model as we have used
historically. Moreover, large support subscription customers, which are the focus of our sales efforts, may demand greater price concessions. As a result, in the



13



---

##### Table of Contents

##### Index to Financial Statements

future we may be required to reduce our prices, which could harm our revenues, gross margins, financial position and cash flows. Furthermore, while the terms of our support subscription
agreements limit the number of supported nodes or the size of supported data sets, such limitations may be improperly circumvented or otherwise bypassed by certain users.

We expect to derive a significant portion of our revenue from renewals of existing support subscription agreements. As a result, customers
renewing and expanding their support subscription relationships with us will be critical to our business. Our support subscription customers have no obligation to renew their support subscriptions after the expiration of the initial support
subscription period and may renew for fewer elements of our support subscription offerings or on different pricing terms. We have limited historical data with respect to support subscription customer renewals, and to date, the majority of our
support subscription agreements have not reached the end of their original term, so we cannot accurately predict support subscription customer renewals. Our support subscription customers renewals may decline or fluctuate as a result of a
number of factors, including their dissatisfaction with our pricing or the Hortonworks Data Platform and their ability to continue their operations and spending levels. If our support subscription customers do not renew their support subscriptions
on similar pricing terms, our revenues may decline and our business could suffer. In addition, over time the average term of our contracts could change based on renewals or for other reasons.

Because we derive substantially all of our revenues and cash flows from supporting the Hortonworks Data Platform and services and
training related to it, failure of these offerings to satisfy customer requirements or to achieve increased market acceptance would harm our business, results of operations, financial condition and growth prospects.

We derive and expect to continue to derive substantially all of our revenues and cash flows from customer fees for support subscription
offerings and professional services in support of the Hortonworks Data Platform. As such, the market acceptance of the Hortonworks Data Platform is critical to our continued success. Demand for the Hortonworks Data Platform is affected by a number
of factors beyond our control, including market acceptance of open source distributed data platforms by referenceable accounts for existing and new use cases, the continued enhancement of the Hortonworks Data Platform to incorporate features and
functionality desired by our support subscription customers, the timing of development and release of new products by our competitors, technological change and growth or contraction in our market. We expect the proliferation of unstructured data to
lead to an increase in the data storage and processing demands of our customers, and the Hortonworks Data Platform may not be able to perform to meet those demands. If we are unable to continue to meet support subscription customer requirements or
to achieve more widespread market acceptance of the Hortonworks Data Platform, our business, results of operations, financial condition and growth prospects will be harmed.

Our success is highly dependent on our ability to penetrate the existing market for open source distributed data platforms as well as
the growth and expansion of the market for open source distributed data platforms.

The market for Hadoop and open source
distributed data platforms is relatively new, rapidly evolving and unproven. Our future success will depend in large part on Hadoops ability to penetrate the existing market for open source distributed data platforms, as well as the continued
growth and expansion of the market for open source distributed data platforms. It is difficult to predict support subscription customer adoption and renewals, support subscription customer demand for our offerings, the size, growth rate and
expansion of these markets, the entry of competitive products or the success of existing competitive products. Our ability to penetrate the existing market and any expansion of the market depends on a number of factors, including the cost,
performance and perceived value associated with our offerings, as well as support subscription customers willingness to adopt an alternative approach to data storage and processing. Furthermore, many potential support subscription customers
have made significant investments in legacy data storage and processing software and may be unwilling to invest in new solutions. If the market for open source distributed data platforms fails to grow or expand or decreases in size, our business
would be harmed.

If we are unable to maintain successful relationships with our partners, our business,
results of operations and financial condition could be harmed.

In addition to our direct sales force and our website, we use
strategic partners, such as distribution partners and resellers, to sell our support subscription offerings and our professional services. We expect that sales through partners will continue to grow as a proportion of our revenues for the
foreseeable future.

Our agreements with our partners are generally non-exclusive, meaning our partners may offer customers the products
and services of several different companies, including products and services that compete with ours, or may themselves be or become competitors. If our partners do not effectively market and sell our support subscription offerings and our
professional services, choose to use greater efforts to market and sell their own products and services or those of our competitors, or fail to meet the needs of our customers, our ability to grow our business and sell our support subscription
offerings and our professional services may be harmed. Our partners may cease marketing our support subscription offerings or professional services with limited or no notice and with little or no penalty. The loss of a substantial number of our
partners, our possible inability to replace them, or the failure to recruit additional partners could harm our results of operations.

Our
ability to achieve revenue growth in the future will depend in part on our success in maintaining successful relationships with our partners, and in helping our partners enhance their ability to independently sell our support subscription offerings
and our professional services. If we are unable to maintain our relationships with these partners, or otherwise develop and expand our indirect distribution channel, our business, results of operations, financial condition or cash flows could be
harmed.

If we are unable to effectively compete, our business and operating results could be harmed.

We face substantial competition from Hadoop distribution vendors such as Cloudera and MapR Technologies, as well as enterprise software and
infrastructure vendors that offer Hadoop distributions such as IBM Corporation and Oracle Corporation. Further, other established system providers not currently focused on Hadoop, including traditional data warehouse solution providers such as
Teradata Corporation, SAP SE and EMC Corporation, or open source distributed data platform providers, including non-relational NoSQL database providers such as MongoDB Inc. and DataStax, Inc., may expand their products and services to compete with
us. Additionally, some potential customers may elect to implement and support Hadoop deployments internally, thus not purchasing a support subscription from us. Some of the companies that compete with us, or that may compete with us in the future,
have greater name recognition, substantially greater financial, technical, marketing and other resources, the ability to devote greater resources to the promotion, sale and support of their solutions, more extensive customer bases and broader
customer relationships and longer operating histories than we have.

We expect competition to increase as other companies continue to
evolve their offerings and as new companies enter our market. Increased competition is likely to result in pricing pressures on our support subscription offerings and our professional services, which could negatively impact our gross margins. If we
are unable to effectively compete, our revenue could decline and our business, operating results and financial condition could be adversely affected.

The competitive position of the Hortonworks Data Platform depends in part on its ability to operate with third-party products and
services, including those of our partners, and, if we are not successful in maintaining and expanding the compatibility of the Hortonworks Data Platform with such products and services, our business will suffer.

The competitive position of the Hortonworks Data Platform depends in part on its ability to operate with products and services of third
parties, including software companies that offer applications designed for various business intelligence applications, software services and infrastructure, and it must be continuously modified and enhanced to adapt to changes in hardware, software,
networking, browser and database technologies. In the future, one or more technology companies, whether our partners or otherwise, may choose not to support the



15



---

##### Table of Contents

##### Index to Financial Statements

operation of their software, software services and infrastructure with the Hortonworks Data Platform, or the Hortonworks Data Platform may not support the capabilities needed to operate with such
software, software services and infrastructure. In addition, to the extent that a third party were to develop software or services that compete with ours, that provider may choose not to support the Hortonworks Data Platform. We intend to facilitate
the compatibility of the Hortonworks Data Platform with various third-party software, software services and infrastructure offerings by maintaining and expanding our business and technical relationships. If we are not successful in achieving this
goal, our business, financial condition and results of operations may suffer.

If open source software programmers, many of whom we
do not employ, do not continue to develop and enhance open source technologies, we may be unable to develop new technologies, adequately enhance our existing technologies or meet customer requirements for innovation, quality and price.

We rely to a significant degree on a number of independent open source software programmers, or Hadoop committers and contributors, to develop
and enhance Apache Hadoop and its related technologies. Additionally, members of the corresponding Apache Software Foundation Project Management Committees, many of whom are not employed by us, are primarily responsible for the oversight and
evolution of the codebases of Hadoop and its related technologies. If the Hadoop committers and contributors fail to adequately further develop and enhance open source technologies, or if the Project Management Committees fail to oversee and guide
the evolution of Hadoop-related technologies in the manner that we believe is appropriate to maximize the market potential of our offerings, then we would have to rely on other parties, or we would need to expend additional resources, to develop and
enhance our offerings. We cannot predict whether further developments and enhancements to these technologies would be available from reliable alternative sources. In either event, our development expenses could be increased and our technology
release and upgrade schedules could be delayed. Delays in developing, completing or delivering new or enhanced offerings could cause our offerings to be less competitive, impair customer acceptance of our offerings and result in delayed or reduced
revenue for our offerings.

Our subscription-based business model may encounter customer resistance or we may experience a decline
in the demand for our offerings.

We provide our support subscription offerings under annual or multi-year subscriptions. A support
subscription generally entitles a support subscription customer to a specified scope of support, as well as security updates, fixes, functionality enhancements and upgrades to the technology and new versions of the software, if and when available,
and compatibility with an ecosystem of certified hardware and software applications. We may encounter support subscription customer resistance to this distribution model or support subscription customers may fail to honor the terms of our support
subscription agreements. To the extent we are unsuccessful in promoting or defending this distribution model, our business, financial condition, results of operations and cash flows could be harmed.

Demand for our offerings may fluctuate based on numerous factors, including the spending levels and growth of our current and prospective
support subscription customers, and general economic conditions. In addition, our support subscription customers generally undertake a significant evaluation process that may result in a prolonged sales cycle. We spend substantial time, effort and
money on our sales efforts, including developing and implementing appropriate go-to-market strategies and training our sales force and ecosystem partners in order to effectively market new solutions, without any assurance that our efforts will
produce any sales. The purchase of our offerings may be discretionary and can involve significant expenditures. If our current and prospective support subscription customers cut costs, then they may significantly reduce their enterprise software
expenditures.

As technologies and the markets for our offerings change, our subscription-based business model may no longer meet the
needs of our support subscription customers. Consequently, we may need to develop new and



16

##### Table of Contents

##### Index to Financial Statements

appropriate marketing and pricing strategies for our solutions. If we are unable to adapt our business model to changes in the marketplace or if demand for our solutions declines, our business,
financial condition, results of operations and cash flows could be harmed.

If we are unable to expand sales to existing customers,
our growth could be slower than we expect and our business and results of operations may be harmed.

Our future growth depends in
part upon expanding sales of our support subscription offerings and our professional services to our existing customers. If our existing customers do not purchase additional support subscription offerings and professional services, our revenues may
grow more slowly than expected, may not grow at all or may decline. Additionally, increasing incremental sales to our current customer base requires increasingly sophisticated and costly sales efforts. There can be no assurance that our efforts will
result in increased sales to existing customers and additional revenues. If our efforts to expand sales to our existing customers are not successful, our business and operating results would be harmed.

Revenue from our largest customers has accounted for a significant percentage of our revenues, and the loss of one or more of our
significant customers would harm our business.

A significant portion of our revenue has been concentrated among a relatively small
number of large customers. For example, Microsoft Corporation accounted for 21.7% of our total revenue for the year ended December 31, 2014, 37.8% of our total revenue for the eight months ended December 31, 2013 and 55.3% of our total
revenue for the year ended April 30, 2013. The revenue from our three largest customers as a group accounted for 42.8% of our total revenue for the year ended December 31, 2014, 50.5% of our total revenue for the eight months ended
December 31, 2013 and 71.0% of our total revenue for the year ended April 30, 2013. While we expect that the revenue from our largest customers will continue to decrease over time as a percentage of our total revenue as we generate more
revenue from other customers, we expect that revenue from a relatively small group of customers will continue to account for a significant portion of our revenue, at least in the near term. Our customer agreements generally do not contain long-term
commitments from our customers, and our customers may be able to terminate their agreements with us prior to expiration of the term. For example, the current term of our agreement with Microsoft expires in July 2015, and automatically renews
thereafter for two successive twelve-month periods unless terminated earlier. The agreement may be terminated by Microsoft prior to the end of its term. Accordingly, the agreement with Microsoft may not continue for any specific period of time.

We may not be able to continue our relationships with any of our largest customers on the same or more favorable terms in future periods
or our relationships may not continue beyond the terms of our existing contracts with them. Our revenue and operating results would suffer if, among other things, any of our largest customers were to renegotiate, terminate, renew on less favorable
terms or fail to renew their agreements with us.

Our future results of operations may fluctuate significantly, and our recent
results of operations may not be a good indication of our future performance.

Our revenue and results of operations could vary
significantly from period to period as a result of various factors, many of which are outside of our control. At the beginning of each quarter, we do not know the number of support subscriptions that we will enter into during the quarter. In
addition, the contract value of our support subscriptions varies substantially among customers, and a single, large support subscription in a given period could distort our results of operations. Comparing our revenue and results of operations on a
period-to-period basis may not be meaningful, and you should not rely on our past results as an indication of our future performance.

We
may not be able to accurately predict our future revenue or results of operations on a quarterly or longer-term basis. We base our current and future expense levels on our operating plans and sales forecasts, and our operating costs are expected to
be relatively fixed in the short-term. As a result, we may not be able to reduce our costs



17

##### Index to Financial Statements

sufficiently to compensate for an unexpected shortfall in revenue, and even a small shortfall in revenue in a quarter could harm our financial results for that quarter and cause our financial
results to fall short of analyst expectations, which could cause the market price of our common stock to decline substantially.

In
addition to other risk factors described in this Risk Factors section, factors that may cause our results of operations to fluctuate from quarter to quarter include:



| |  |  | the timing of new customer contracts for support subscription offerings and professional services, and the extent to which we earn additional
revenue from existing customers as they expand their deployment of the Hortonworks Data Platform;
| | - |  | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | the renewals of our support subscription arrangements with our customers;
| | - |  | -------------------------------------------------------------------------



| |  |  | changes in the competitive dynamics of our market;
| | - |  | --------------------------------------------------



| |  |  | customers delaying purchasing decisions in anticipation of new software or software enhancements;
| | - |  | -------------------------------------------------------------------------------------------------



| |  |  | the timing of satisfying revenue recognition criteria and our ability to obtain vendor-specific objective evidence of fair value, or VSOE, for our
support subscription offerings;
| | - |  | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | our ability to control costs, including our operating expenses;
| | - |  | ---------------------------------------------------------------



| |  |  | the proportion of revenue attributable to larger transactions as opposed to smaller transactions and the impact that a change in such proportion
may have on the overall average selling price of our support subscription offerings;
| | - |  | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | the proportion of revenue attributable to support subscription offerings and professional services, which may impact our gross margins and
operating income;
| | - |  | ------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | the reduction or elimination of support of the Apache Hadoop Project by the Apache Software Foundation, migration of Hadoop technology to an
organization other than the Apache Software Foundation, or any other actions taken by the Apache Software Foundation or the Apache Hadoop Project that may impact our business model;
| | - |  | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | changes in customers budgets and in the timing of their purchasing decisions;
| | - |  | ------------------------------------------------------------------------------



| |  |  | the collectability of receivables from customers and resellers, which may be hindered or delayed if these customers or resellers experience
financial distress; and
| | - |  | -------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | general economic conditions, both domestically and internationally, as well as economic conditions specifically affecting industries in which our
customers participate.
| | - |  | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------

Many of these factors are outside of our control, and the variability and unpredictability of
such factors could result in our failing to meet or exceed our financial expectations for a given period. We believe that quarter-to-quarter comparisons of our revenue, results of operations and cash flows may not necessarily be indicative of our
future performance.

Our sales cycle is long and unpredictable, particularly with respect to large support subscription customers,
and our sales efforts require considerable time and expense.

Our results of operations may fluctuate, in part, because of the
resource-intensive nature of our sales efforts, the length and variability of the sales cycle of our support subscription offerings and the difficulty in making short-term adjustments to our operating expenses. Our results of operations depend in
part on sales to large support subscription customers and increasing sales to existing customers. The length of our sales cycle, from initial evaluation to payment for our support subscription offerings is generally six to nine months, but can vary
substantially from customer to customer. Our sales cycle can extend to more than a year for some customers. It is difficult to predict exactly when, or even if, we will make a sale to a potential customer or if we can increase sales to our existing
customers. As a result, large individual sales have, in some cases, occurred in quarters subsequent to those we anticipated, or have not occurred at all. The loss or delay of one or more large



18

##### Table of Contents

##### Index to Financial Statements

transactions in a quarter could impact our results of operations for that quarter and any future quarters for which revenue from that transaction is lost or delayed. As a result of these factors,
it is difficult for us to forecast our revenues accurately in any quarter. Because a substantial proportion of our expenses are relatively fixed in the short term, our results of operations will suffer if revenue falls below our expectations in a
particular quarter, which could cause the price of our common stock to decline.

We have experienced rapid growth in recent periods.
If we fail to manage our growth effectively, we may be unable to execute our business plan or maintain high levels of service and our financial results could be negatively impacted.

We have increased our number of full-time employees to 601 at December 31, 2014 from 171 at December 31, 2012 and have increased our
revenue to $46.0 million in the year ended December 31, 2014 from $4.8 million in the eight months ended December 31, 2012. Our recent growth and expansion has placed, and our anticipated growth may continue to place, a significant strain
on our managerial, administrative, operational, financial and other resources. We intend to continue to expand our overall business, customer base, headcount and operations. Continued growth increases the challenges involved in:



| |  |  | recruiting, training and retaining sufficient skilled technical, marketing, sales and management personnel;
| | - |  | -----------------------------------------------------------------------------------------------------------



| |  |  | preserving our culture, values and entrepreneurial environment;
| | - |  | ---------------------------------------------------------------



| |  |  | developing and improving our internal administrative infrastructure, particularly our financial, operational, compliance, recordkeeping,
communications and other internal systems;
| | - |  | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | managing our international operations and the risks associated therewith;
| | - |  | -------------------------------------------------------------------------



| |  |  | maintaining high levels of satisfaction with our solutions among our customers; and
| | - |  | -----------------------------------------------------------------------------------



| |  |  | effectively managing expenses related to any future growth.
| | - |  | -----------------------------------------------------------

If we fail to manage our growth effectively, our business, results of operations and financial condition could suffer.

Our future success depends in large part on the growth of the market for big data applications, and an increase in the desire to store
and process big data, and we cannot be sure that the market for big data applications will grow as expected or, even if such growth occurs, that our business will grow at similar rates, or at all.

Our ability to increase the adoption of the Hortonworks Data Platform, increase sales of support subscription offerings and professional
services, and grow our business depends on the increased adoption of big data applications by enterprises. While we believe that big data applications can offer a compelling value proposition to many enterprises, the broad adoption of big data
applications also presents challenges to enterprises, including developing the internal expertise and infrastructure to manage big data applications effectively, coordinating multiple data sources, defining a big data strategy that delivers an
appropriate return on investment and implementing an information technology infrastructure and architecture that enables the efficient deployment of big data solutions. Accordingly, our expectations regarding the potential for future growth in the
market for big data applications, and the third-party growth estimates for this market in this Annual Report on Form 10-K, are subject to significant uncertainty. If the market for big data applications does not grow as expected, our business
prospects may be adversely affected. Even if the market for big data applications increases, we cannot be sure that our business will grow at a similar rate, or at all.

Because of the characteristics of open source software, there are few technological
barriers to entry into the open source market by new competitors and it may be relatively easy for competitors, some of which may have greater resources than we have, to enter our markets and compete with us.

One of the characteristics of open source software is that anyone may modify and redistribute the existing open source software and use it to
compete in the marketplace. Such competition can develop without the degree of overhead and lead time required by traditional proprietary software companies. It is possible for competitors with greater resources than ours to develop their own open
source software, including software based on one or more components of Hadoop or the Hortonworks Data Platform, potentially reducing the demand for our solutions and putting price pressure on our support subscription offerings and our professional
services. We cannot guarantee that we will be able to compete successfully against current and future competitors or that competitive pressure or the availability of new open source software will not result in price reductions, reduced operating
margins and loss of market share, any one of which could harm our business, financial condition, results of operations and cash flows.

Our software development and licensing model could be negatively impacted if the Apache License, Version 2.0 is not enforceable or is
modified so as to become incompatible with other open source licenses.

The Hortonworks Data Platform has been provided under the
Apache License 2.0. This license states that any work of authorship licensed under it, and any derivative work thereof, may be reproduced and distributed provided that certain conditions are met. It is possible that a court would hold this license
to be unenforceable or that someone could assert a claim for proprietary rights in a program developed and distributed under it. Any ruling by a court that this license is not enforceable, or that open source components of the Hortonworks Data
Platform may not be reproduced or distributed, may negatively impact our distribution or development of all or a portion of the Hortonworks Data Platform. In addition, at some time in the future it is possible that Apache Hadoop may be distributed
under a different license or the Apache License 2.0 may be modified, which could, among other consequences, negatively impact our continuing development or distribution of the software code subject to the new or modified license. Further, full
utilization of the Hortonworks Data Platform may depend on applications and services from various third parties, and in the future these applications or services may not be available to our customers on commercially reasonable terms, or at all,
which could harm our business.

We do not currently have vendor-specific objective evidence of fair value for support subscription
offerings, and we may offer certain contractual provisions to our customers that result in delayed recognition of revenue under GAAP, which could cause our results of operations to fluctuate significantly from period-to-period in ways that do not
correlate with our underlying business performance.

In the course of our selling efforts, we typically enter into sales
arrangements pursuant to which we provide support subscription offerings and professional services. We refer to each individual product or service as an element of the overall sales arrangement. These arrangements typically require us to
deliver particular elements in a future period. We apply software revenue recognition rules under U.S. generally accepted accounting principles, or GAAP. In certain cases, when we enter into more than one contract with a single customer, the group
of contracts may be so closely related that they are viewed under GAAP as one multiple-element arrangement for purposes of determining the appropriate amount and timing of revenue recognition. As we discuss further in Managements
Discussion and Analysis of Financial Condition and Results of OperationsCritical Accounting Policies and EstimatesRevenue Recognition, because we do not have VSOE for our support subscription offerings, and because we may offer
certain contractual provisions to our customers, such as delivery of support subscription offerings and professional services, or specified functionality, or because multiple contracts signed in different periods may be viewed as giving rise to
multiple elements of a single arrangement, we may be required under GAAP to defer revenue to future periods. Typically, for arrangements providing for support subscription offerings and professional services, we have recognized as revenue the entire
arrangement fee ratably over the support subscription period, although the appropriate timing of revenue recognition must be evaluated on an arrangement-by-arrangement basis and may differ from arrangement to

arrangement. If we are unexpectedly required to defer revenue to future periods for a significant portion of our sales, our revenue for a particular period could fall below our expectations or
those of securities analysts and investors, resulting in a decline in our stock price.

Because we recognize revenue from
subscriptions for our services over the term of the subscription, downturns or upturns in sales may not be immediately reflected in our results of operations.

We generally recognize subscription revenue from support subscription customers ratably over the term of their subscription agreements, which
are generally 12 months, with some support subscription customers having subscription agreements with longer terms. As a result, much of the revenue we report in each quarter is deferred revenue from subscription agreements entered into during
previous quarters. Consequently, a decline in the value of new support subscription agreements entered in any one quarter will not necessarily be fully reflected in the revenue we record in that quarter and will harm our revenue in future quarters.
In addition, we may be unable to adjust our cost structure to reflect this reduced revenue. Accordingly, the effect of significant downturns in sales and market acceptance of our services may not be fully reflected in our results of operations until
future periods. Our subscription model also makes it difficult for us to rapidly increase our revenue through additional sales in any period, as revenue from new support subscription customers must be recognized over the applicable subscription
term.

Any failure to offer high-quality support subscription offerings may harm our relationships with our support subscription
customers and results of operations.

Once the Hortonworks Data Platform is deployed, our support subscription customers depend on
our software support organization to resolve technical issues relating to the deployment. We may be unable to respond quickly enough to accommodate short-term increases in support subscription customer demand for support subscription offerings. We
also may be unable to modify the format of our support subscription offerings to compete with changes in offerings provided by our competitors. Increased support subscription customer demand for our support subscription offerings, without
corresponding revenues, could increase costs and harm our results of operations. In addition, our sales process is highly dependent on our business reputation and on positive recommendations from our existing support subscription customers. Any
failure to maintain high-quality support subscription offerings, or a market perception that we do not maintain high-quality support subscription offerings, could harm our reputation, our ability to sell our support subscription offerings to
existing and prospective support subscription customers and our results of operations.

If we fail to comply with our customer
contracts, our business could be harmed.

Any failure by us to comply with the specific provisions in our customer contracts could
result in the imposition of various penalties, which may include termination of contracts, forfeiture of profits and suspension of payments. Further, any negative publicity related to our customer contracts or any proceedings surrounding them,
regardless of its accuracy, may damage our business and affect our ability to compete for new contracts. If our customer contracts are terminated, or if our ability to compete for new contracts is adversely affected, our business, financial
condition, results of operations and cash flows could be harmed.

The Hortonworks Data Platform may contain defects that may be
costly to correct, delay market acceptance of our solutions and expose us to claims and litigation.

Despite our testing
procedures, errors, including security vulnerabilities or incompatibilities with third-party software and hardware, have been and may continue to be found in the Hortonworks Data Platform after deployment. This risk is increased by the fact that
much of the code in the Hortonworks Data Platform is developed by independent parties over whom we may not exercise supervision or control. If errors are discovered, we may have to make significant expenditures of capital and devote significant
technical resources to analyze, correct, eliminate or manage them, and we may not be able to successfully do so in a timely manner, or at all. Errors and failures in the Hortonworks Data Platform could result in a loss of, or delay in, market

acceptance of our enterprise technologies, loss of existing or potential customers and delayed or lost revenue and could damage our reputation and our ability to convince enterprise users of the
benefits of the Hortonworks Data Platform.

In addition, errors in the Hortonworks Data Platform could cause system failures, loss of data
or other adverse effects for our customers who may assert warranty and other claims for substantial damages against us. Although our agreements with our customers often contain provisions that seek to limit our exposure to such claims, it is
possible that these provisions may not be effective or enforceable under the laws of some jurisdictions. While we seek to insure against these types of claims, our insurance policies may not adequately limit our exposure to such claims. These
claims, even if unsuccessful, could be costly and time consuming to defend and could harm our business, financial condition, results of operations and cash flows.

Incorrect or improper implementation or use of the Hortonworks Data Platform could result in customer dissatisfaction and harm our
business, results of operations, financial condition and growth prospects.

The Hortonworks Data Platform is deployed in a wide
variety of technology environments, including in large-scale, complex technology environments, and we believe our future success will depend at least in part on our ability to support such deployments. Hadoop itself is technically very complicated,
and it is not easy to maximize the value of the Hortonworks Data Platform without proper implementation and training. We often must assist our customers in achieving successful implementations for large, complex deployments. If our customers are
unable to implement the Hortonworks Data Platform successfully, or in a timely manner, customer perceptions of our company and the Hortonworks Data Platform may be impaired, our reputation and brand may suffer, and customers may choose not to renew
their subscriptions or increase their purchases of our support subscription offerings or professional services.

Our customers and
partners may need training in the proper use of and the variety of benefits that can be derived from the Hortonworks Data Platform to maximize its potential. The Hortonworks Data Platform may perform inadequately if it is not implemented or used
correctly or as intended. The incorrect or improper implementation or use of the Hortonworks Data Platform, our failure to train customers on how to efficiently and effectively use the Hortonworks Data Platform, or our failure to provide effective
support subscription offerings or professional services to our customers, may result in negative publicity or legal claims against us. Also, as we continue to expand our customer base, any failure by us to properly provide these services will likely
result in lost opportunities for follow-on sales of our support subscription offerings and professional services.

Interruptions or
performance problems associated with our technology and infrastructure may harm our business and results of operations.

Our
website and internal technology infrastructure may experience performance issues due to a variety of factors, including infrastructure changes, human or software errors, website or third-party hosting disruptions or capacity constraints due to a
number of potential causes, including technical failures, natural disasters or fraud or security attacks. If our security is compromised, our website is unavailable or our users are unable to download the Hortonworks Data Platform or order support
subscription offerings or professional services within a reasonable amount of time or at all, our business could be harmed. We expect to continue to make significant investments to maintain and improve website performance and to enable rapid
releases of new features and applications for the Hortonworks Data Platform. To the extent that we do not effectively upgrade our systems as needed and continually develop our technology and network architecture to accommodate actual and anticipated
changes in technology, our business and results of operations may be harmed.

In addition, we rely on SaaS technologies from third parties
in order to operate critical functions of our business, including financial management services from NetSuite Inc., customer relationship management services from salesforce.com, Inc. and lead generation management services from Marketo, Inc. If
these services become unavailable due to extended outages or interruptions or because they are no longer available on commercially reasonable terms or prices, our expenses could increase, our ability to manage our finances could be interrupted,

our processes for managing sales of our support subscription offerings and professional services and supporting our customers could be impaired, and our ability to generate and manage sales leads
could be weakened until equivalent services, if available, are identified, obtained and implemented, all of which could harm our business and results of operations.

We depend on our executive officers and other key employees, and the loss of one or more of these employees or an inability to attract
and retain highly skilled employees could harm our business.

Our success depends largely upon the continued services of our
executive officers and other key employees, including many Hadoop committers. We rely on our leadership team in the areas of research and development, operations, security, marketing, sales, support and general and administrative functions, and on
individual contributors in our research and development. From time to time, there may be changes in our executive management team resulting from the hiring or departure of executives, which could disrupt our business. We do not have employment
agreements with our executive officers or other key personnel that require them to continue to work for us for any specified period and, therefore, they could terminate their employment with us at any time. The loss of one or more of our key
employees or executive officers could harm our business.

In addition, to execute our growth plan, we must attract and retain highly
qualified personnel. Competition for such personnel in the San Francisco Bay Area, where our headquarters is located, and in other locations where we maintain offices, is intense, especially for engineers experienced in designing and developing
software and Apache Hadoop applications and experienced sales professionals. The Apache Hadoop Project relies on Hadoop committers for the projects technical management. While we currently employ a large number of Hadoop core committers and
innovators, one becomes a committer by invitation only. As a result, the market to hire such individuals is very competitive. If our employees who are Hadoop core committers terminate their employment with us, we could lose our ability to innovate
the core open source technology, define the roadmap for the future of Hadoop, distribute predictable and reliable enterprise quality releases, and provide comprehensive support to our customers. We have, from time to time, experienced, and we expect
to continue to experience, difficulty in hiring and retaining employees with appropriate qualifications. Many of the companies with which we compete for experienced personnel have greater resources than we have. If we hire employees from competitors
or other companies, their former employers may attempt to assert that these employees or we have breached legal obligations, resulting in a diversion of our time and resources. In addition, job candidates and existing employees often consider the
value of the equity awards they receive in connection with their employment. If the perceived value of our equity awards declines, it may harm our ability to recruit and retain highly skilled employees. If we fail to attract new personnel or fail to
retain and motivate our current personnel, our business and future growth prospects could be harmed.

If we do not effectively
expand and train our sales force, we may be unable to add new customers or increase sales to our existing customers and our business will be harmed.

We continue to be substantially dependent on our sales force to obtain new customers and to drive additional use cases among our existing
customers. We believe that there is significant competition for sales personnel, including enterprise sales representatives and sales engineers, with the skills and technical knowledge that we require. In particular, there is significant demand for
sales engineers with Hadoop expertise. Our ability to achieve significant revenue growth will depend, in large part, on our success in recruiting, training and retaining sufficient numbers of sales personnel to support our growth. New hires require
significant training and may take significant time before they achieve full productivity. Our recent hires and planned hires may not become productive as quickly as we expect, and we may be unable to hire or retain sufficient numbers of qualified
individuals in the markets where we do business or plan to do business. In addition, as we continue to grow rapidly, a large percentage of our sales force will have relatively little experience working with us, our support subscription offerings and
our business model. If we are unable to hire and train sufficient numbers of effective sales personnel, or our sales personnel are not successful in obtaining new customers or increasing sales to our existing customer base, our business will be
harmed.

If we are not successful in expanding our international business, we may incur additional
losses and our revenue growth could be harmed.

Our future results depend, in part, on our ability to expand into international
markets. We also have a number of distributor and reseller relationships for our support subscription offerings and professional services in international markets. Our ability to expand internationally will depend upon our ability to deliver
functionality and foreign language translations that reflect the needs of the international clients that we target. Our ability to expand internationally involves various risks, including the need to invest significant resources in such expansion,
and the possibility that returns on such investments will not be achieved in the near future or at all in these less familiar competitive environments. We may also choose to conduct our international business through strategic alliances. If we are
unable to identify strategic alliance partners or negotiate favorable alliance terms, our international growth may be harmed. In addition, we have incurred and may continue to incur significant expenses in advance of generating material revenues as
we attempt to establish our presence in particular international markets.

Expanding our business internationally will also require
significant attention from our management and will require us to add additional management and other resources in these markets. Our ability to expand our business, attract talented employees and enter into strategic alliances in an increasing
number of international markets requires considerable management attention and resources and is subject to the particular challenges of supporting a rapidly growing business in an environment of multiple languages, cultures, customs, legal systems,
alternative dispute systems, regulatory systems, commercial infrastructures and technology infrastructure. If we are unable to grow our international operations in a timely manner, we may incur additional losses and our revenue growth could be
harmed.

As we expand internationally, our business will become more susceptible to risks associated with international operations.

We principally sell our offerings through sales personnel in the United States, Australia, Brazil, France, Germany, India, Japan,
Korea, the Netherlands, Sweden and the United Kingdom and currently have operations in the United States and in London, United Kingdom. We also have development teams in India and Kiev, Ukraine and a number of distributor and reseller relationships
for our support subscription offerings and our professional services in other international markets. Conducting international operations subjects us to risks that we have not generally faced in the United States. These risks include:



| |  |  | fluctuations in currency exchange rates;
| | - |  | ----------------------------------------



| |  |  | unexpected changes in foreign regulatory requirements;
| | - |  | ------------------------------------------------------



| |  |  | potentially different pricing environments and longer sales cycles;
| | - |  | -------------------------------------------------------------------



| |  |  | difficulties in managing the staffing of international operations;
| | - |  | ------------------------------------------------------------------



| |  |  | potentially adverse tax consequences, including the complexities of foreign value-added tax systems, restrictions on the repatriation of earnings
and changes in tax rates;
| | - |  | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | dependence on strategic alliance partners to increase client acquisition;
| | - |  | -------------------------------------------------------------------------



| |  |  | the burdens of complying with a wide variety of foreign laws and different legal standards;
| | - |  | -------------------------------------------------------------------------------------------



| |  |  | increased financial accounting and reporting burdens and complexities;
| | - |  | ----------------------------------------------------------------------



| |  |  | political, social and economic instability abroad, particularly with our development team in Ukraine;
| | - |  | -----------------------------------------------------------------------------------------------------



| |  |  | laws and business practices favoring local competitors;
| | - |  | -------------------------------------------------------



| |  |  | terrorist attacks and security concerns in general; and
| | - |  | -------------------------------------------------------



| |  |  | reduced or varied protection for intellectual property rights in some countries.
| | - |  | --------------------------------------------------------------------------------

The occurrence of any one of these risks could harm our international business and, consequently,
our results of operations. Additionally, operating in international markets requires significant management attention and financial resources. We cannot be certain that the investment and additional resources required to operate in other countries
will produce desired levels of revenue or profitability.

We have made strategic acquisitions in the past and intend to do so in the
future. If we are unable to find suitable acquisitions or partners, or to achieve expected benefits from such acquisitions or partnerships, our business, financial condition, results of operations and prospects could be harmed.

As part of our ongoing business strategy to expand our suite of solutions and acquire new technology, from time to time we engage in
discussions with third parties regarding, and enter into agreements relating to, possible acquisitions, strategic alliances and joint ventures. In May 2014, we acquired new technology, know-how and solutions through our acquisition of XA Secure, a
data security company. There may be significant competition for acquisition targets in our industry, or we may not be able to identify suitable acquisition candidates, negotiate attractive terms for acquisitions or complete acquisitions on expected
timelines, or at all. If we are unable to complete strategic acquisitions or do not realize the expected benefits of the acquisitions we do complete, our business, financial condition, results of operations and prospects could be harmed.

Even if we are able to complete acquisitions or enter into alliances and joint ventures that we believe will be successful, such transactions
are inherently risky. Significant risks associated with these transactions, include:



| |  |  | failing to achieve anticipated synergies, including with respect to complementary software or services;
| | - |  | -------------------------------------------------------------------------------------------------------



| |  |  | losing key employees of the acquired businesses;
| | - |  | ------------------------------------------------



| |  |  | integration and restructuring costs, both one-time and ongoing;
| | - |  | ---------------------------------------------------------------



| |  |  | maintaining sufficient controls, policies and procedures;
| | - |  | ---------------------------------------------------------



| |  |  | diversion of managements attention from ongoing business operations;
| | - |  | ---------------------------------------------------------------------



| |  |  | establishing new informational, operational and financial systems to meet the needs of our business;
| | - |  | ----------------------------------------------------------------------------------------------------



| |  |  | our inability to maintain the key business relationships and the reputations of the businesses we acquire;
| | - |  | ----------------------------------------------------------------------------------------------------------



| |  |  | uncertainty of entry into markets in which we have limited or no prior experience and in which competitors have stronger market positions;
| | - |  | ------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | our dependence on unfamiliar affiliates and partners of the companies we acquire;
| | - |  | ---------------------------------------------------------------------------------



| |  |  | insufficient revenue to offset our increased expenses associated with acquisitions;
| | - |  | -----------------------------------------------------------------------------------



| |  |  | potentially incurring accounting charges as we transition an acquired company to our open-source business model;
| | - |  | ----------------------------------------------------------------------------------------------------------------



| |  |  | our responsibility for the liabilities of the businesses we acquire; and
| | - |  | ------------------------------------------------------------------------



| |  |  | unanticipated and unknown liabilities.
| | - |  | --------------------------------------

If we are not successful in completing acquisitions in the future or do not realize the expected benefits of the acquisitions we do complete,
we may be required to reevaluate our acquisition strategy. We also may incur substantial expenses and devote significant management time and resources in seeking to complete acquisitions, some of which may ultimately not be consummated or not result
in expected benefits. The occurrence of any of these acquisition-related risks could harm our business, financial condition, results of operations and prospects.

Our continued success depends on our ability to maintain and enhance strong brands.

We believe that the brand identities that we have developed have contributed significantly to the success of our business. We also believe that
maintaining and enhancing our brands is important to expanding our customer



25

base and attracting talented employees. In order to maintain and enhance our brands, we may be required to make further investments that may not be successful. Maintaining our brands will depend
in part on our ability to remain a leader in open source technology and our ability to continue to provide high-quality offerings. If we fail to promote and maintain our brands, or if we incur excessive costs in doing so, our business, financial
condition, results of operations and cash flows may be harmed.

Our efforts to protect our intellectual property rights may not be
adequate to prevent third parties from misappropriating our intellectual property rights in our know-how, software and trademarks.

We have developed proprietary methodologies, know-how and software related to software development, testing and quality assurance. Failure to
adequately protect and defend our intellectual property rights in these areas may diminish the value of the Hortonworks Data Platform, impair our ability to compete effectively and harm our business.

In addition, the protective steps we have taken in the past may be inadequate to protect and deter misappropriation of our trademark rights.
We may be unable to detect the unauthorized use of, or take appropriate steps to enforce, our trademark rights in a timely manner. We have registered trademarks in the United States, Canada and the European Community and have trademark applications
pending in various other international jurisdictions. Effective trademark protection may not be available in every country in which we offer or intend to distribute our solutions. We may be unable to prevent third parties from acquiring domain names
that are similar to, infringe upon, or diminish the value of our trademarks and other proprietary rights. Failure to adequately protect our trademark rights could damage or even destroy one or more of our brands and impair our ability to compete
effectively. Furthermore, defending or enforcing our trademark rights could result in the expenditure of significant financial and managerial resources.

We may be subject to intellectual property rights claims by third parties, which are extremely costly to defend, could require us to pay
significant damages and could limit our ability to use certain technologies.

Companies in the software and technology industries,
including some of our current and potential competitors, own large numbers of patents, copyrights, trademarks and trade secrets and frequently enter into litigation based on allegations of infringement or other violations of intellectual property
rights. In addition, many of these companies can dedicate substantially greater resources to enforce their intellectual property rights, and to defend claims that may be brought against them, than we can. We have received, and we and the Apache
Hadoop Project may in the future receive, notices that claim we have misappropriated, misused, or infringed other parties intellectual property rights, and, to the extent Hadoop gains greater market visibility, we and the Apache Hadoop Project
face a higher risk of being the subject of intellectual property infringement claims.

Any intellectual property infringement claims, with
or without merit, could be very time-consuming, could be expensive to settle or litigate and could divert our managements attention and other resources. These claims could also subject us to significant liability for damages, potentially
including treble damages if we are found to have willfully infringed patents or copyrights. These claims could also result in our having to stop using technology found to be in violation of a third partys rights. We might be required to seek a
license for the intellectual property, which may not be available on reasonable terms or at all. Even if a license were available, we could be required to pay significant royalties, which would increase our operating expenses. As a result, we may be
required to develop alternative non-infringing technology, which could require significant effort and expense. Any of these results would harm our business, results of operations, financial condition and cash flows.

Federal, state, foreign government and industry regulations, as well as self-regulation related to privacy and data security concerns
pose the threat of lawsuits and other liability.

We do not generally collect and utilize demographic and other information,
including personally identifiable information, from and about users (such as customers, potential customers, and others). Users may, however,



26



---

##### Table of Contents

##### Index to Financial Statements

provide personal information to us in many contexts such as when signing up for certain services, registering for seminars, participating in a survey, connecting with other users and Hadoop
experts in our forums, participating in Hortonworks University classes, participating in polls or signing up to receive e-mail newsletters.

Within the United States, various federal and state laws and regulations govern the collection, use, retention, sharing and security of the
data we receive from and about users. Outside of the United States, various jurisdictions actively regulate and enforce laws regarding the collection, retention, transfer and use (including loss and unauthorized access) of personal information.
Privacy advocates and government bodies have increasingly scrutinized the ways in which companies link personal identities and data associated with particular users or devices with data collected through the internet, and we expect such scrutiny to
continue to increase. Loss, retention or misuse of certain information and alleged violations of laws and regulations relating to privacy and data security, and any relevant claims, may expose us to potential liability and may require us to expend
significant resources on data security and in responding to and defending such allegations and claims.

Security and privacy
breaches may hurt our business.

Any security breach, unauthorized access, unauthorized usage, virus or similar breach or
disruption could result in the loss of confidential information, damage to our reputation, early termination of our contracts, litigation, regulatory investigations or other liabilities. If our, our customers or our partners security
measures are breached as a result of third-party action, employee error, malfeasance or otherwise and, as a result, someone obtains unauthorized access to data, our reputation will be damaged, our business may suffer and we could incur significant
liability.

Techniques used to obtain unauthorized access or to sabotage systems change frequently and generally are not recognized until
launched against a target. As a result, we may be unable to anticipate these techniques or to implement adequate preventative measures. If an actual or perceived security breach occurs, the market perception of our security measures could be harmed
and we could lose sales and customers. Any significant violations of data privacy could result in the loss of business, litigation and regulatory investigations and penalties that could damage our reputation and adversely impact our results of
operations and financial condition. Moreover, if a high-profile security breach occurs with respect to another Hadoop provider, our customers and potential customers may lose trust in the security of Hadoop-based solutions generally, which could
adversely impact our ability to retain existing customers or attract new ones.

Prolonged economic uncertainties or downturns could
harm our business.

Current or future economic downturns could harm our business and results of operations. Negative conditions in
the general economy both in the United States and abroad, including conditions resulting from financial and credit market fluctuations and terrorist attacks in the United States, Europe or elsewhere, could cause a decrease in corporate spending on
enterprise software in general and slow down the rate of growth of our business.

General worldwide economic conditions have experienced,
and in the future may experience, a significant downturn. These conditions make it extremely difficult for our customers and us to forecast and plan future business activities accurately, and they could cause our customers to reevaluate their
decision to purchase our offerings, which could delay and lengthen our sales cycles or result in cancellations of planned purchases. Furthermore, during challenging economic times our customers may face issues in gaining timely access to sufficient
credit, which could impair their ability to make timely payments to us. If that were to occur, we may be required to increase our allowance for doubtful accounts, which would harm our results of operations.

We have a significant number of customers in the business services, advertising, financial services, healthcare and pharmaceuticals, high
technology, manufacturing, media and entertainment, oil and gas, online services, retail and telecommunications industries. A substantial downturn in any of these industries may cause firms to react to worsening conditions by reducing their capital
expenditures in general or by specifically reducing their spending on information technology. Customers in these industries may delay or cancel information technology



27

##### Table of Contents

##### Index to Financial Statements

projects or seek to lower their costs by renegotiating vendor contracts. To the extent purchases of our offerings are perceived by customers and potential customers to be discretionary, our
revenues may be disproportionately affected by delays or reductions in general information technology spending. Also, support subscription customers may choose to develop or utilize in-house support capabilities as an alternative to purchasing our
support subscription offerings or professional services. Moreover, competitors may respond to market conditions by lowering prices of support subscription offerings. In addition, the increased pace of consolidation in certain industries may result
in reduced overall spending on our support subscription offerings or professional services.

We cannot predict the timing, strength or
duration of any economic slowdown, instability or recovery, generally or within any particular industry. If the economic conditions of the general economy or industries in which we operate worsen from present levels, our business, results of
operations, financial condition and cash flows could be harmed.

We may require additional capital to support business growth, and
this capital might not be available on acceptable terms, if at all.

We intend to continue to make investments to support our
business growth and may require additional funds to respond to business challenges, including the need to develop new features or otherwise enhance the Hortonworks Data Platform, improve our operating infrastructure or acquire complementary
businesses and technologies. Accordingly, we may need to engage in equity or debt financings to secure additional funds. If we raise additional funds through future issuances of equity or convertible debt securities, our existing stockholders could
suffer significant dilution, and any new equity securities we issue could have rights, preferences and privileges superior to those of holders of our common stock. Any debt financing that we may secure in the future could involve restrictive
covenants relating to our capital raising activities and other financial and operational matters, which may make it more difficult for us to obtain additional capital and to pursue business opportunities, including potential acquisitions. We may not
be able to obtain additional financing on terms that are favorable to us, if at all. If we are unable to obtain adequate financing or financing on terms that are satisfactory to us when we require it, our ability to continue to support our business
growth and to respond to business challenges could be significantly impaired, and our business may be harmed.

If our goodwill or
amortizable intangible assets become impaired, we may be required to record a significant charge to earnings.

Under GAAP, we
review our amortizable intangible assets for impairment when events or changes in circumstances indicate the carrying value may not be recoverable. Goodwill is required to be tested for impairment at least annually. Factors that may be considered a
change in circumstances indicating that the carrying value of our goodwill or amortizable intangible assets may not be recoverable include a decline in stock price and market capitalization, reduced future cash flow estimates and slower growth rates
in our industry. We may be required to record a significant charge to earnings in our financial statements during the period in which any impairment of our goodwill or amortizable intangible assets is determined, which could harm our results of
operations.

Our ability to use our net operating losses to offset future taxable income may be subject to certain limitations.

As of December 31, 2014, we had federal and state net operating loss carryforwards, or NOLs, of $124.0 million and $142.5
million, respectively, due to prior period losses. In general, under Section 382 of the Internal Revenue Code of 1986, as amended, or the Code, a corporation that undergoes an ownership change is subject to limitations on its
ability to utilize its NOLs to offset future taxable income. Our existing NOLs may be subject to limitations arising from previous ownership changes, including in connection with our initial public offering, and if we undergo an ownership change in
the future, our ability to utilize NOLs could be further limited by Section 382 of the Code. Future changes in our stock ownership, some of which are outside of our control, could result in an ownership change under Section 382 of the
Code. Furthermore, our ability to utilize NOLs of companies that we may acquire in the future may be subject to limitations. There is also a risk that, due to



28



---

##### Table of Contents

##### Index to Financial Statements

regulatory changes, such as suspensions on the use of NOLs, or other unforeseen reasons, our existing NOLs could expire or otherwise be unavailable to offset future income tax liabilities. For
these reasons, we may not be able to realize a tax benefit from the use of our NOLs, whether or not we attain profitability.

We
have business and customer relationships with certain entities who are stockholders or affiliated with our directors, or both, and conflicts of interest may arise because of such relationships.

Some of our customers and other business partners are affiliated with certain of our directors or hold shares of our capital stock, or
both. For example, we have entered into strategic partnerships and/or customer relationships with Yahoo! Inc., Red Hat, Inc., Teradata Corporation and Hewlett-Packard Company. Our directors Jay Rossiter, Paul Cormier and Martin Fink are
employees of Yahoo! Inc., Red Hat, Inc. and Hewlett-Packard Company, respectively, and each of Yahoo! Inc., Hewlett-Packard Company and Teradata Corporation are stockholders. We believe that the transactions and agreements that we have entered
into with related parties are on terms that are at least as favorable as could reasonably have been obtained at such time from third parties. However, these relationships could create, or appear to create, potential conflicts of interest when our
board of directors is faced with decisions that could have different implications for us and these other parties or their affiliates. In addition, conflicts of interest may arise between us and these other parties and their affiliates. The
appearance of conflicts, even if such conflicts do not materialize, might adversely affect the publics perception of us, as well as our relationship with other companies and our ability to enter into new relationships in the future, including
with competitors of such related parties, which could harm our business and results of operations.

Catastrophic events may disrupt
our business.

Our corporate headquarters are located in Santa Clara, California and we utilize data centers that are located in
North America. Additionally, we rely on our network and third-party infrastructure and enterprise applications, internal technology systems and our website for our development, marketing, operational support, hosted services and sales activities.
The west coast of the United States contains active earthquake zones. In the event of a major earthquake, hurricane, or catastrophic event such as fire, power loss, telecommunications failure, cyber-attack, war, or terrorist attack, we may be unable
to continue our operations and may endure system interruptions, reputational harm, delays in our application development, extended interruptions in the Hortonworks Data Platform, breaches of data security and loss of critical data, all of which
could harm our future results of operations.

Risks Related to Ownership of Our Common Stock

Our stock price may be volatile or may decline regardless of our operating performance resulting in substantial losses for our
stockholders.

The trading price of our common stock is likely to be volatile and could fluctuate widely regardless of our
operating performance. The market price of our common stock may fluctuate significantly in response to numerous factors, many of which are beyond our control, including:



| |  |  | actual or anticipated fluctuations in our results of operations;
| | - |  | ----------------------------------------------------------------



| |  |  | the financial projections we may provide to the public, any changes in these projections or our failure to meet these projections;
| | - |  | ----------------------------------------------------------------------------------------------------------------------------------



| |  |  | failure of securities analysts to initiate or maintain coverage of our company, changes in financial estimates and publication of other news by any
securities analysts who follow our company, or our failure to meet these estimates or the expectations of investors;
| | - |  | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | ratings changes by any securities analysts who follow our company;
| | - |  | ------------------------------------------------------------------



| |  |  | announcements by us or our competitors of significant technical innovations, acquisitions, strategic partnerships, joint ventures, or capital
commitments;
| | - |  | ----------------------------------------------------------------------------------------------------------------------------------------------------------

In addition, the stock markets have experienced extreme price and volume fluctuations that have affected and continue to affect the market
prices of equity securities of many technology companies. Stock prices of many technology companies have fluctuated in a manner unrelated or disproportionate to the operating performance of those companies. In the past, stockholders have instituted
securities class action litigation following periods of market volatility. If we were to become involved in securities litigation, it could subject us to substantial costs, divert resources and the attention of management from operating our
business, and harm our business, results of operations, financial condition and cash flows.

Anti-takeover provisions in our charter
documents and under Delaware law could make an acquisition of our company more difficult, limit attempts by our stockholders to replace or remove our current management and limit the market price of our common stock.

Provisions in our amended and restated certificate of incorporation and bylaws may have the effect of delaying or preventing a change of
control or changes in our management. Our amended and restated certificate of incorporation and bylaws include provisions that:



| |  |  | authorize our board of directors to issue, without further action by the stockholders, shares of undesignated preferred stock with terms, rights
and preferences determined by our board of directors that may be senior to our common stock;
| | - |  | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | require that any action to be taken by our stockholders be effected at a duly called annual or special meeting and not by written consent;
| | - |  | ------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | specify that special meetings of our stockholders can be called only by our board of directors, the Chair of our board of directors, or our Chief
Executive Officer;
| | - |  | --------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | establish an advance notice procedure for stockholder proposals to be brought before an annual meeting, including proposed nominations of persons
for election to our board of directors;
| | - |  | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | establish that our board of directors is divided into three classes, Class I, Class II and Class III, with each class serving three-year staggered
terms;
| | - |  | ---------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | prohibit cumulative voting in the election of directors;

| |  |  | provide that our directors may be removed only for cause;
| | - |  | ---------------------------------------------------------



| |  |  | provide that vacancies on our board of directors may be filled only by a majority of directors then in office, even though less than a quorum; and
| | - |  | --------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | require the approval of our board of directors or the holders of at least seventy-five percent (75%) of our outstanding shares of capital
stock to amend our bylaws and certain provisions of our amended and restated certificate of incorporation.
| | - |  | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

These
provisions may frustrate or prevent any attempts by our stockholders to replace or remove our current management by making it more difficult for stockholders to replace members of our board of directors, which is responsible for appointing the
members of our management. In addition, because we are incorporated in Delaware, we are governed by the provisions of Section 203 of the Delaware General Corporation Law, which generally prohibits a Delaware corporation from engaging in any of
a broad range of business combinations with any interested stockholder for a period of three years following the date on which the stockholder became an interested stockholder. Any delay or prevention of a change of control
transaction or changes in our management could cause the market price of our common stock to decline.

We are an emerging
growth company and we cannot be certain if the reduced disclosure requirements applicable to emerging growth companies will make our common stock less attractive to investors.

We are an emerging growth company, as defined in the federal securities laws, and we may take advantage of certain exemptions from
various reporting requirements that are applicable to other public companies that are not emerging growth companies including, but not limited to, not being required to comply with the auditor attestation requirements of Section 404
of the Sarbanes-Oxley Act of 2002, or the Sarbanes-Oxley Act, reduced disclosure obligations regarding executive compensation in our periodic reports and proxy statements, and exemptions from the requirements of holding a nonbinding advisory vote on
executive compensation and stockholder approval of any golden parachute payments not previously approved. For as long as we continue to be an emerging growth company, we intend to take advantage of certain of these exemptions. We cannot predict if
investors will find our common stock less attractive because we may rely on these exemptions. If some investors find our common stock less attractive as a result, there may be a less active trading market for our common stock and our stock price may
be more volatile.

Section 107 of the JOBS Act provides that an emerging growth company can take advantage of an extended
transition period for complying with new or revised accounting standards. However, we chose to opt out of such extended transition period, and as a result, we will comply with new or revised accounting standards on the relevant dates
adoption of such standards is required for non-emerging growth companies. Our decision to opt out of the extended transition period for complying with new or revised accounting standards is irrevocable.

We will remain an emerging growth company until the earliest of: (i) the last day of the fiscal year following the five-year
anniversary of the completion of our initial public offering; (ii) the end of the fiscal year in which we have more than $1.0 billion in annual revenue; (iii) the end of the fiscal year in which we qualify as a large accelerated
filer, with at least $700 million of equity securities held by non-affiliates as of the end of the second quarter of such fiscal year; and (iv) the date on which we have, during the previous three-year period, issued more than $1.0
billion in non-convertible debt securities.

The requirements of being a public company may strain our resources, divert
managements attention, and affect our ability to attract and retain executive management and qualified board members.

As a
public company, we are subject to the reporting requirements of the Exchange Act, the Sarbanes-Oxley Act, the Dodd-Frank Wall Street Reform and Consumer Protection Act of 2010, the listing requirements of the exchanges and other markets upon which
our common stock is listed, and other applicable securities rules and regulations.

Compliance with these rules and regulations will continue to increase our legal and financial
compliance costs, make some activities more difficult, time-consuming, or costly, and increase demand on our systems and resources, particularly after we are no longer an emerging growth company. The Exchange Act requires, among other
things, that we file annual, quarterly and current reports with respect to our business and results of operations. The Sarbanes-Oxley Act requires, among other things, that we maintain effective disclosure controls and procedures and internal
control over financial reporting. In order to maintain and, if required, improve our disclosure controls and procedures and internal control over financial reporting to meet this standard, significant resources and management oversight may be
required. We are required to disclose changes made in our internal control and procedures on a quarterly basis and we are required to furnish a report by management on, among other things, the effectiveness of our internal control over financial
reporting for the first fiscal year beginning after the effective date of our initial public offering. However, our independent registered public accounting firm is not required to formally audit and attest to the effectiveness of our internal
control over financial reporting pursuant to Section 404 until the later of the year following our first annual report required to be filed with the SEC, or the date we are no longer an emerging growth company. As a result of the
complexity involved in complying with the rules and regulations applicable to public companies, our managements attention may be diverted from other business concerns, which could harm our business and results of operations. Although we have
already hired additional employees to assist us in complying with these requirements, we may need to hire more employees in the future or engage outside consultants, which will increase our operating expenses.

In addition, changing laws, regulations and standards relating to corporate governance and public disclosure are creating uncertainty for
public companies, increasing legal and financial compliance costs, and making some activities more time-consuming. These laws, regulations and standards are subject to varying interpretations, in many cases due to their lack of specificity, and, as
a result, their application in practice may evolve over time as new guidance is provided by regulatory and governing bodies. This could result in continuing uncertainty regarding compliance matters and higher costs necessitated by ongoing revisions
to disclosure and governance practices. We intend to invest substantial resources to comply with evolving laws, regulations and standards, and this investment may result in increased general and administrative expenses and a diversion of
managements time and attention from business operations to compliance activities. If our efforts to comply with new laws, regulations and standards differ from the activities intended by regulatory or governing bodies due to ambiguities
related to their application and practice, regulatory authorities may initiate legal proceedings against us and our business may be harmed.

Being a public company and these new rules and regulations will continue to make it more expensive for us to obtain director and officer
liability insurance, and in the future we may be required to accept reduced coverage or incur substantially higher costs to obtain coverage. These factors could also make it more difficult for us to attract and retain qualified members of our board
of directors, particularly to serve on our audit committee and compensation committee, and qualified executive officers.

As a result of
disclosure of information in our filings with the SEC, our business and financial condition has become more visible, which we believe may result in threatened or actual litigation, including by competitors and other third parties. If such claims are
successful, our business and results of operations could be harmed, and even if the claims do not result in litigation or are resolved in our favor, these claims, and the time and resources necessary to resolve them, could divert the resources of
our management and harm our business and results of operations.

We do not intend to pay dividends on our common stock so any
returns will be limited to changes in the value of our common stock.

We have never declared or paid any cash dividends on our
common stock. We currently anticipate that we will retain future earnings for the development, operation and expansion of our business, and do not anticipate declaring or paying any cash dividends for the foreseeable future. Any return to
stockholders will therefore be limited to the increase, if any, of our stock price, which may never occur.

If securities or industry analysts do not publish research or publish inaccurate or
unfavorable research about our business, our stock price and trading volume could decline.

The trading market for our common stock
depends in part on the research and reports that securities or industry analysts publish about us or our business. If few securities analysts commence coverage of us, or if industry analysts cease coverage of us, the trading price for our common
stock would be negatively affected. If one or more of the analysts who cover us downgrade our common stock or publish inaccurate or unfavorable research about our business, our common stock price would likely decline. If one or more of these
analysts cease coverage of us or fail to publish reports on us regularly, demand for our common stock could decrease, which might cause our common stock price and trading volume to decline.

Substantial future sales of our common stock in the public market could cause our stock price to fall.

Additional sales of our common stock in the public market, or the perception that these sales could occur, could cause the market price of our
common stock to decline. As of December 31, 2014, we had 42,724,814 shares of common stock outstanding. As a result of market stand-off agreements, 35,041,245 shares of our common stock are subject to restrictions on their sale for 180 days
after December 12, 2014 (subject in some cases to volume limitations). In addition, certain of these shares are also subject to lock-up agreements with the underwriters. Further, as of December 31, 2014, there were outstanding options and
warrants to purchase 17,736,512 shares of our common stock that, if exercised, will result in these additional shares becoming available for sale upon expiration of the lock-up agreements and market stand-off agreements. Goldman, Sachs &
Co. may, in its sole discretion, permit our officers, director, employees and current stockholders who are subject to lock-up agreements to sell shares prior to the expiration of the lock-up agreements.

The holders of an aggregate of 26,552,648 shares of our common stock, including the holder of warrants to purchase 3,250,000 shares of
our common stock and 476,368 shares of our common stock as of December 31, 2014, have rights, subject to some conditions, to require us to file registration statements covering their shares or to include their shares in registration statements
that we may file for ourselves or our stockholders. We have also registered shares of common stock that we may issue under our employee equity incentive plans. These shares may be sold freely in the public market upon issuance, subject to certain
market stand-off or lock-up agreements.

Our charter documents designate the Court of Chancery of the State of Delaware as the sole
and exclusive forum for certain types of actions and proceedings that may be initiated by our stockholders, which could limit our stockholders ability to obtain a favorable judicial forum for disputes with us or our directors, officers, or
other employees.

Our amended and restated certificate of incorporation and bylaws provide that, unless we consent in writing to
the selection of an alternative forum, the Court of Chancery of the State of Delaware shall be the sole and exclusive forum for (i) any derivative action or proceeding brought on our behalf, (ii) any action asserting a claim of breach of a
fiduciary duty owed by any of our directors, officers or other employees to us or our stockholders, (iii) any action asserting a claim arising pursuant to any provision of the Delaware General Corporation Law, our amended and restated
certificate of incorporation or our bylaws, or (iv) any action asserting a claim against us governed by the internal affairs doctrine. Any person or entity purchasing or otherwise acquiring any interest in shares of our capital stock shall be
deemed to have notice of and consented to the provisions of our amended and restated certificate of incorporation described above. This choice of forum provision may limit a stockholders ability to bring a claim in a judicial forum that it
finds favorable for disputes with us or our directors, officers, or other employees, which may discourage such lawsuits against us and our directors, officers and other employees. Alternatively, if a court were to find these provisions of our
amended and restated certificate of incorporation inapplicable to, or unenforceable in respect of, one or more of the specified types of actions or proceedings, we may incur additional costs associated with resolving such matters in other
jurisdictions, which could harm our business, financial condition, or results of operations.

None.

Item 2. Properties.

We lease office facilities around the world totaling approximately 102,000 square feet, including 65,000 square feet of space for our
corporate headquarters, which includes research and development, sales, marketing, business operations and executive offices, in Santa Clara, California pursuant to a lease that expires in April 2018. We believe that our facilities are adequate to
meet our needs for the immediate future, and that, should it be needed, suitable additional space will be available to accommodate expansion of our operations.

Item 3. Legal Proceedings.

From time to time, we are involved in legal proceedings and subject to claims arising in the ordinary course of our business. Although the
results of litigation and claims cannot be predicted with certainty, we currently believe that the final outcome of these ordinary course matters will not have a material adverse effect on our business, operating results, financial condition or cash
flows. 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.

Item 5. Market for Registrants Common Equity, Related Stockholder Matters and Issuer Purchases of Equity Securities.

Market Information for Common Stock

Our common stock has been listed on the NASDAQ Global Select Market under the symbol HDP since December 12, 2014. Prior to
that date, there was no public trading market for our common stock. The following table sets forth for the periods indicated the intra-day high and low sales prices per share of our common stock as reported on the NASDAQ Global Select Market:



|                                        |  |      |       |  |     |   |       |

Holders of Record

As of March 20, 2015, we had approximately 174 holders of record of our common stock. The actual number of stockholders is significantly
greater than this number of record holders, and includes stockholders who are beneficial owners, but whose shares are held in street name by brokers and other nominees. This number of holders of record also does not include stockholders whose shares
may be held in trust by other entities.

Dividend Policy

We have never declared or paid cash dividends on our common stock. We currently intend to retain any future earnings and do not expect to pay
any dividends in the foreseeable future. Any determination to pay dividends in the future will be at the discretion of our Board of Directors and will be dependent on a number of factors, including our earnings, capital requirements and overall
financial condition.

Equity Compensation Plan Information

See Item 12, Security Ownership of Certain Beneficial Owners and Management and Related Stockholder Matters for information
regarding securities authorized for issuance.

Use of Proceeds

The Registration Statement on Form S-1 (File No. 333-200044) for our initial public offering of our common stock was declared effective by
the SEC on December 11, 2014. The Registration Statement on Form S-1 registered an aggregate of 7,187,500 shares of our common stock, including 937,500 shares registered to cover an option to purchase additional shares that we granted to the
underwriters of our initial public offering. On December 17, 2014, we closed our initial public offering and sold 7,187,500 shares of our common stock at a public offering price of $16.00 per share for an aggregate offering price of
$115.0 million. Upon completion of the sale of the shares of our common stock referenced in the precedent sentence, our initial public offering terminated. There has been no material change in the planned use of proceeds from our initial public
offering as described in our final prospectus filed with the SEC on December 12, 2014 pursuant to Rule 424(b)(4).

The
underwriters of our initial public offering were Goldman, Sachs & Co., Credit Suisse Securities (USA) LLC, RBC Capital Markets, LLC, Pacific Crest Securities LLC, Wells Fargo Securities, LLC and Blackstone Advisory Partners L.P.. We
paid to the underwriters of our initial public offering an underwriting discount totaling $8.1 million. In addition, we incurred expenses of approximately $5.1 million which, when added to the underwriting discount, amount to total expenses of
approximately $13.2 million. Thus, the net offering proceeds, including the concurrent private placement, after deducting underwriting discounts and offering expenses, were approximately $109.6 million. No payments were made to our directors or
officers or their associates, holders of 10% or more of any class of our equity securities or any affiliates.

Warrant Issuance

In June 2014, we issued a warrant to purchase 476,368 shares of our common stock with an exercise price per share of $8.46 to Yahoo! Inc. The
warrant was issued to Yahoo! in exchange for the amendment of certain rights held by Yahoo! under the Amended and Restated Investors Rights Agreement, dated November 25, 2014, by and between us and certain holders of our common stock and
the holders of our outstanding convertible preferred stock to approve certain corporate transactions involving Hortonworks.

Concurrent Private
Placement

In December 2014, we sold 486,486 shares of our common stock at a purchase price of $16.00 per share for an aggregate
purchase price of approximately $7.8 million to Passport Capital.

None of the foregoing transactions involved any underwriters,
underwriting discounts or commissions, or any public offering. We believe the offers, sales and issuances of the above securities were exempt from registration under the Securities Act by virtue of Section 4(2) of the Securities Act because the
issuance of securities to the recipients did not involve a public offering, or in reliance on Rule 701 because the transactions were pursuant to compensatory benefit plans or contracts relating to compensation as provided under such rule. The
recipients of the securities in each of these transactions represented their intentions to acquire the securities for investment only and not with a view to or for sale in connection with any distribution thereof, and appropriate legends were placed
upon the stock certificates issued in these transactions. All recipients had adequate access, through their relationships with us, to information about us. The sales of these securities were made without any general solicitation or advertising.

Key MetricGross Billings

We have included gross billings, a non-GAAP financial measure, in this annual report because it is a key measure used by our
board of directors and management to monitor our near term cash flows and manage our business. Gross billings is calculated as total non-GAAP revenue plus the change in deferred revenue for the same period. As we have not yet established
vendor-specific objective evidence of fair value for our support subscriptions, we recognize revenue ratably over the period beginning when both the support subscription and professional services have commenced for customers with agreements that
purchase both a support subscription and professional services. Most of our customer agreements include both support subscription and professional services. The accounting treatment for such agreements causes the recognition of our revenue to trail
the impact of these customer agreements and creates significant deferred revenue balances.

We have provided a
reconciliation between total revenue, the most directly comparable GAAP financial measure, and gross billings in the table below. We believe gross billings provides useful information to investors and others in understanding and evaluating our
operating results in the same manner as our board of directors and management.

Item 7. Managements Discussion and Analysis of Financial Condition and
Results of Operations.

The following discussion and analysis of our financial condition and results of operations
should be read together with Selected Consolidated Financial Data and the consolidated financial statements and related notes included elsewhere in this annual report. This discussion contains forward-looking statements based upon
current expectations that involve risks and uncertainties. Our actual results may differ materially from those anticipated in these forward-looking statements as a result of various factors, including those discussed in Risk Factors and
in other parts of this annual report.

Overview

We seek to advance the market adoption of Hadoop and provide enterprises with a new data management solution that enables them
to harness the power of big data to transform their businesses through more effective and efficient management of their valuable data assets. A Hadoop cluster combines commodity servers with local storage and an open source software distribution to
create a reliable distributed compute and storage platform for large data sets scalable up to PBs, with thousands of servers or nodes. Our solution is an enterprise-grade data management platform built on a unique distribution of Apache Hadoop and
powered by YARN. Our approach is differentiated in that we are committed to serving the Apache Software Foundation open source ecosystem and to sharing all of our product developments with the open source community. We distribute the Hortonworks
Data Platform software under the Apache open source license in order to provide broad rights for recipients of the software to use, copy, modify and redistribute the software. Consistent with our open source approach, we generally make the
Hortonworks Data Platform available free of charge and derive the predominant amount of our revenue from support subscription offerings and professional services.

We generate revenue by selling support subscription offerings and professional services. Our support subscription agreements
are typically annual arrangements. We price our support subscription offerings based on the number of servers in a cluster, or nodes, data under management and/or the scope of support provided. Accordingly, our support subscription revenue varies
depending on the scale of our customers deployments and the scope of the support agreement. Professional services revenue is derived from consulting services engagements and training services. Our consulting services are provided primarily on
a time and materials basis, and to a lesser extent, a fixed fee basis, and training services are priced based on attendance. The growth of our total revenue is dependent upon (i) new customer acquisition, (ii) expansion of sales within our
existing customer base and (iii) the annual renewal of our support subscription agreements by our existing support subscription customers. Our revenue is subject to fluctuations based upon our success at addressing these factors but may also be
impacted by the revenue recognition requirements of our multiple-element customer arrangements. Our early growth strategy has been aimed at acquiring customers for our support subscription offerings via a direct sales force and delivering consulting
services. As we grow our business, our longer-term strategy will be to expand our partner network and leverage our partners to deliver a larger proportion of professional services to our customers on our behalf. The implementation of this strategy
is expected to result in an increase in upfront costs in order to establish and further cultivate such strategic partnerships, but we expect that it will increase gross margins in the long term as the percentage of our revenue derived from
professional services, which has a lower gross margin than our support subscriptions, decreases.

Our ability to
successfully implement these strategies is subject to challenges, risks and uncertainties and our net losses have been increasing year over year. In our efforts to achieve profitability, we have placed and will continue to place an emphasis on
investing within our support subscription sales efforts to try to drive increased revenue in both support subscriptions and professional services. If these support subscription sales efforts are not successful, due to unsuccessful execution by
us, increased competition in our markets, or other factors, we will find it difficult to add new support subscription customers, and our revenue will not grow as quickly as we would like, and may decline. In addition, our longer-term strategy
of leveraging our partners to provide an increasing proportion of professional services to our customers presents certain challenges. This strategy requires us to make upfront expenditures and devote time and attention to cultivating
relationships. If we are unable to identify and engage suitable partners that are able to provide such services, or if our partners are unable to provide

professional services at the quality level that our customers expect, we may not be able to achieve this transition as quickly as we would like, or at all. We expect that our ability to
successfully implement this strategy will have a material impact on whether we can achieve profitability, due to the difference in gross margins on our support subscriptions versus our professional services. If the percentage of our total
revenue that comes from professional services does not decrease over time as we expect, or we are not able to establish VSOE for professional services revenue, then our ability to achieve profitability will be negatively impacted.

We have had a few agreements with, and equity issuances to, certain of our early, large customers that have had a significant
impact on our historical results and that will continue to impact our reported GAAP results at least through the current fiscal quarter. These transactions were:



| |  |  | In July 2011, we issued a warrant to purchase 6,500,000 shares of Series A preferred stock at an exercise price of $0.005 per share (which was
convertible into 3,250,000 shares of common stock) to Yahoo! Inc., a related party. The warrant was issued in connection with our Series A financing and the transactions contemplated thereby, including commercial agreements with Yahoo! providing for
support subscription offerings and certain rights to technology. The warrant expires nine years from the date of issuance and became exercisable for common stock upon the consummation of our initial public offering in December 2014. As the warrant
was issued to a customer, the vesting of the warrant upon the consummation of our initial public offering resulted in an immediate $4.0 million reduction in revenue, which was the cumulative revenue from Yahoo! since our inception. The $48.0 million
difference between the fair value as of the date of our initial public offering of the warrant of $52.0 million and the reduction in revenue was recognized in cost of revenue during the fourth quarter of the year ended December 31, 2014. The
$52.0 million fair value of the warrant was recognized in additional paid-in capital in our consolidated balance sheet.

| |  |  | In February 2012, we entered into a multi-year agreement with Teradata Corporation, a related party, whereby we will provide development, support,
training and other professional services to Teradata and Teradatas end-user customers. In April 2012, Teradata made a non-refundable $9.5 million prepayment that will be used to credit amounts owed for end-user support and professional
services that we may provide under the agreement. As of December 31, 2014, $6.1 million of the $9.5 million prepayment remained in deferred revenue.

| |  |  | In July 2012, we entered into a multi-year subscription arrangement with Microsoft Corporation as a customer and partner in order to enable the
Hortonworks Data Platform to execute on the Windows Server and Azure Cloud platforms. The arrangement consisted of an initial co-engineering effort with Microsoft, which, except for ongoing standard maintenance, was completed in October 2013,
followed primarily by ongoing support subscription offerings. Microsoft contributed significantly to our early revenue (22% of total revenue for the year ended December 31, 2014, 38% and 58% of total revenue for the eight months ended
December 31, 2013 and 2012, respectively, and 55% and 27% of total revenue for the years ended April 30, 2013 and 2012, respectively). We expect the revenues from Microsoft to continue to decrease as a percentage of our total revenue in
the future as we generate more revenue from other customers.

| |  |  | In September 2013, we entered into a commercial agreement and common stock purchase agreement with AT&T covering the sale and issuance of
390,269 shares of our common stock to an affiliate of AT&T at a per share price of $0.0002. The shares were fully vested as of January 30, 2014. As a result of the issuance of shares to a customer at below fair value, we recorded
contra-revenue in the amount of $2.0 million for the year ended December 31, 2014, and $0.4 million for the eight months ended December 31, 2013.

| |  |  | In June 2014, we issued a warrant to purchase up to 1.0% of our shares of common stock outstanding at the issuance date at an exercise price of
$8.46 per share to Yahoo! Inc., a related party. The warrant was issued to Yahoo! in exchange for the amendment of certain rights held by Yahoo! under the Investors Rights Agreement to approve certain corporate transactions involving
Hortonworks. The warrant expires nine years from the date of issuance and became exercisable upon the consummation of

As of December 31, 2014, the warrant is exercisable for 476,368 shares of our common stock. The combined value of the initial measurement and the change in the fair value of this warrant of $5.4 million was recorded as other expense
in our consolidated statement of operations for the year ended December 31, 2014. As of December 31, 2014, this amount is also recorded as additional paid-in capital in our consolidated balance sheet.

In December 2014, we entered into a stock purchase agreement with Passport Capital, pursuant to which funds affiliated with
Passport Capital purchased 486,486 shares of our common stock at $16.00 per share in the concurrent private placement that closed immediately subsequent to the closing of our initial public offering.

We have achieved significant growth in recent periods. For the year ended December 31, 2014, our revenue was $46.0
million. For the eight months ended December 31, 2013 and 2012, our revenue was $17.9 million and $4.8 million, respectively. For the years ended April 30, 2013 and 2012, our revenue was $11.0 million and $1.6 million,
respectively. For the year ended December 31, 2014, our gross billings was $87.1 million. For the eight months ended December 31, 2013 and 2012, our gross billings were $29.4 million and $9.7 million, respectively. For the
years ended April 30, 2013 and 2012, our gross billings were $17.6 million and $11.8 million, respectively. We incurred net losses of $177.4 million for the year ended December 31, 2014, $46.2 million and $19.7 million for
the eight months ended December 31, 2013 and 2012, respectively, and $36.6 million and $11.5 million for the years ended April 30, 2013 and 2012, respectively. See Selected Financial DataKey MetricGross
Billings for more information and a reconciliation of gross billings to total revenue, the most directly comparable GAAP financial measure, and an explanation of why management uses this non-GAAP financial measure.

Change in Fiscal Year

We changed our fiscal year end from April 30 to December 31, commencing with our fiscal year ended December 31,
2013.

Key Factors Affecting Our Performance

Adding New Support Subscription Customers. Growth of our revenue from our support subscription offerings is
driven by agreements with new support subscription customers, renewals of existing support subscription agreements and increased revenues from existing support subscription customers. The number of agreements with new support subscription customers
signed may vary from period to period for several reasons, including the length of our sales cycle, the effectiveness of our sales and marketing efforts and overall adoption rates of Hadoop-based solutions. The contract value of our support
subscriptions with individual support subscription customers varies substantially among customers, and our results of operations may fluctuate from period to period depending on the timing of particular large support subscriptions. Our results
of operations may also fluctuate, in part, because of the resource-intensive nature of our sales efforts, the length and variability of the sales cycle of our support subscription offerings and the difficulty in making short-term adjustments to our
operating expenses. The length of our sales cycle from initial evaluation to payment for our support subscription offerings is generally six to nine months, but can extend to one year or more for some customers. In addition, because our professional
services engagements frequently relate to initial new support subscription customer deployments of the Hortonworks Data Platform, growth in our professional services revenue is driven primarily by adding new support subscription customers.

Additional Sales to Existing Support Subscription Customers. Our existing support subscription
customers continue to represent a large opportunity for us to expand our revenue base. Growth of our revenue from existing support subscription customers typically comes when customers increase the scale of their deployment of the Hortonworks Data
Platform. We price our support subscription offerings based on the number of nodes, data

under management and/or the scope of services provided. Accordingly, our revenues from our support subscription offerings vary depending on the scale of our support subscription customers
deployments and the scope of the support agreement.

Investing in Growth. We will continue to
focus on long-term growth. We believe that our market opportunity is large and underpenetrated, and we will continue to invest significantly in sales and marketing to grow our customer base, expand within existing support subscription customers and
grow internationally to drive additional revenue. We also expect to invest in research and development to enhance the Hortonworks Data Platform. To support our expected growth, we plan to invest in other operational and administrative functions. We
expect to use the proceeds from our initial public offering and the concurrent private placement to fund these growth strategies and do not expect to be profitable in the near future. We also intend to leverage business partners for the delivery of
professional services. We believe that our sales and marketing, research and development and general and administrative costs will decrease as a percentage of revenue in the long term as we are able to reach economies of scale and achieve process
improvements and other operational efficiencies. With this increased operating leverage, we expect our gross and operating margins to increase in the long term.

Revenue Recognition Policies. We typically enter into sales arrangements pursuant to which we
provide both support subscription offerings and professional services. Pursuant to software revenue recognition rules under GAAP, for arrangements providing both support subscription offerings and professional services, we typically recognize as
revenue the entire arrangement fee ratably over the subscription period, although the appropriate timing of revenue recognition must be evaluated on an arrangement-by-arrangement basis. See Critical Accounting Policies and
EstimatesRevenue Recognition. The costs associated with our support subscription and professional services revenue are expensed as we incur the delivery costs. However, in many cases, the related revenue is deferred and recognized
ratably over a later period. Thus, during times of rapid customer growth and accompanying delivery of professional services, our gross margin is expected to be negatively impacted.

Key Business Metrics

We review a number of metrics, including the following key metrics, to evaluate our business, measure our performance, identify
trends affecting our business, formulate business plans and make strategic decisions. These key business metrics include the following:

Dollar-Based Net Expansion Rate. We believe that our ability to retain our customers and expand their
support subscription revenue over time will be an indicator of the stability of our revenue base and the long-term value of our customer relationships. Maintaining customer relationships allows us to sustain and increase revenue to the extent
customers maintain or increase the number of nodes, data under management and/or the scope of the support subscription agreements. To date, only a small percentage of our customer agreements have reached the end of their original terms and, as a
result, we have not observed a large enough sample of renewals to derive meaningful conclusions. Based on our limited experience, we observed a dollar-based net expansion rate of 144% as of December 31, 2014. We calculate dollar-based net
expansion rate as of a given date as the aggregate annualized subscription contract value as of that date from those customers that were also customers as of the date 12 months prior, divided by the aggregate annualized subscription contract value
from all customers as of the date 12 months prior. We calculate annualized support subscription contract value for each support subscription customer as the total subscription contract value as of the reporting date divided by the number of years
for which the support subscription customer is under contract as of such date. We last reported a dollar-based net expansion rate of 125% as of September 30, 2014. For the full year, the dollar-based net expansion rate is 144%, which represents
a trailing four-quarter average for the twelve-month period ended December 31, 2014.

Total subscription contract
value for a support subscription customer account is a legal and contractual determination made by assessing the contractual terms of each support subscription, as of the date of determination, as to the subscription fees we expect to receive for
that support subscription, assuming no changes to the subscription. The total subscription contract value is not determined by reference to historical or future

revenue, deferred revenue or any other GAAP financial measure over any period. It is forward-looking and contractually derived as of the date of determination, and the period over which any
associated revenue is recognized is affected by our revenue recognition policies under GAAP.

Total support
subscription customers. We believe total support subscription customers is a key indicator of our market penetration, growth and future revenues. In order to grow our customer base, we have aggressively invested in and intend to
continue to invest in our direct sales team, as well as to pursue additional partnerships within our indirect sales channel. We generally define a support subscription customer as an entity with an active support subscription as of the measurement
date. In situations where there are multiple contracts with multiple subsidiaries or divisions, universities, or governmental organizations of a single entity, the entity is counted once. Our total support subscription customer count was 332 as of
December 31, 2014.

Components of Results of Operations

Revenue

We
generate revenue primarily under multiple-element arrangements that include support subscription offerings combined with consulting and/or training services. We have not yet established vendor-specific objective evidence of fair value, or VSOE, for
our support subscriptions. Accordingly, for our multiple-element arrangements, we recognize revenue on a ratable basis over the period beginning when both the support subscription and professional services have commenced, and ending at the
conclusion of the support subscription or professional services period, whichever is longer.

Cost of Revenue

Cost of support subscription revenue consists primarily of personnel costs (including salaries, benefits, and stock-based
compensation) for employees associated with our support subscription offerings mainly related to technology support and allocated shared costs. Cost of professional services revenue consists primarily of personnel costs (including salaries, benefits
and stock-based compensation) for employees and fees to subcontractors associated with our professional service contracts, travel costs and allocated shared costs. We allocate shared costs such as rent, shared information technology costs, and
employee benefit costs to all departments based on headcount. As such, allocated shared costs are reflected in cost of revenue and each operating expense category. Additionally, during the year ended December 31, 2014, cost of support
subscription and professional services revenue included expenses of $47.4 million and $0.6 million, respectively, related to the vesting of the 2011 Yahoo! Warrant upon our initial public offering. Cost of revenue for support subscription and
professional services is expensed as incurred.

Operating Expenses

Sales and Marketing. Sales and marketing expenses consist primarily of personnel costs (including salaries,
benefits and stock-based compensation) for our sales and marketing employees. In addition, sales and marketing expenses include the cost of advertising, online marketing, promotional events, corporate communications, product marketing and other
brand-building activities. We expect our sales and marketing expenses to continue to increase in absolute dollars for the foreseeable future as we continue to invest in our selling and marketing activities, building brand awareness, attracting new
customers and sponsoring additional marketing events. However, we expect our sales and marketing expenses to decrease as a percentage of our total revenue over the long term.

Research and Development. Research and development expenses consist primarily of personnel costs (including
salaries, benefits and stock-based compensation) for our research and development employees, costs associated with subcontractors and equipment lease expenses. We expect to continue to focus our research and development efforts on enhancing and
adding new features and functionality to the Hortonworks Data Platform. As a result, we expect our research and development expenses to continue to increase in absolute dollars for the foreseeable future. However, we expect our research and
development expenses to decrease as a percentage of our total revenue over the long term.

General and Administrative. General and administrative expenses
consist primarily of personnel costs (including salaries, benefits and stock-based compensation) for our executive, finance, human resources, IT and other administrative employees. In addition, general and administrative expenses include fees for
third-party professional services, including consulting, legal and accounting services and other corporate expenses and allocated overhead. We expect our general and administrative expenses to continue to increase in absolute dollars for the
foreseeable future as we continue to invest in the growth of our business. However, we expect our general and administrative expenses to decrease as a percentage of our total revenue over the long term.

Support subscription revenue increased by $14.1 million or 124% for the year ended December 31, 2014 compared to the
eight months ended December 31, 2013. This increase includes a $5.6 million net contra-support subscription revenue adjustment period over period, related to the 2011 Yahoo! Warrant of $4.0 million and the issuance of equity to an affiliate of
AT&T of $2.0 million for the year ended December 31, 2014. This was offset by the contra-support subscription revenue impact of the issuance of equity to an affiliate of AT&T of $0.4 million for the eight months ended December 31,
2013. Excluding the $5.6 million net contra-support subscription revenue impact of the 2011 Yahoo! Warrant and equity issued to an affiliate of AT&T, gross support subscription revenue increased by $19.7 million for the year ended
December 31, 2014 compared to the eight months ended December 31, 2013. Of the $19.7 million increase, approximately $10.5 million is attributable to the extra four months of support subscription revenue during the year ended
December 31, 2014 compared to the eight months ended December 31, 2013. The remaining increase of $9.2 million is due to the significant growth in our support subscription customer base as well as sales of additional support subscriptions
to our existing customers.

Professional services revenue increased $14.0 million or 218% for the year ended
December 31, 2014 compared to the eight months ended December 31, 2013. Excluding the $0.1 million net contra-professional services revenue impact of the 2011 Yahoo! Warrant and equity issued to an affiliate of AT&T, gross professional
services revenue increased by $14.2 million for the year ended December 31, 2014 compared to the eight months ended December 31, 2013. Of the $14.2 million increase, approximately $6.9 million is attributable to the extra four months of
professional services revenue during the year ended December 31, 2014 compared to

the eight months ended December 31, 2013. The remaining increase of $7.3 million is due to the significant growth in our support subscription customer base and sales of additional
professional services to our existing customers. While the percentage of total revenue from professional services for the year ended December 31, 2014 on a GAAP basis was approximately 44% of total revenue, the percentage of total revenue from
professional services before contra-revenue adjustments for the same period was approximately 39%, which is more in line with prior periods. See Selected Financial Data for further discussion of such contra-revenue adjustments.

Cost of support subscription revenue increased $49.0 million for the year ended
December 31, 2014 compared to the eight months ended December 31, 2013. This increase includes a $47.4 million expense related to the vesting of the 2011 Yahoo! Warrant upon our initial public offering in December 2014. This was offset by
a $2.5 million decrease in the cost of support subscription revenue allocation for the eight months ended December 31, 2013 related to joint engineering efforts with Microsoft to develop the Hortonworks Data Platform for Windows, resulting in a
net $44.9 million increase. The remaining $4.1 million increase was partially attributable to the extra four months of cost of support subscription revenue of approximately $1.8 million during the year ended December 31, 2014 as compared to the
eight months ended December 31, 2013, after excluding the impact of the $47.4 million charge related to the vesting of the 2011 Yahoo! Warrant. The remaining increase of $2.3 million was primarily due to a $1.8 million increase in employee
costs related to our increased headcount.

2013. The remaining increase of $25.8 million was primarily due to an increase in employee compensation of $19.4 million related to our increased headcount and an increase in marketing expenses of $2.6 million. In addition, travel, rent and
equipment expenses increased by $3.0 million in order to support our growth.

Research and development expenses increased $23.2 million for the year ended December 31, 2014 compared to the eight
months ended December 31, 2013. Of the increase, $2.5 million was due to the 2013 allocation to cost of sales of expenses incurred under the Microsoft agreement to build a Hadoop solution for Windows which today is known as HDInsight. The
remaining $20.7 million increase was partially attributable to the extra four months of research and development expenses of approximately $12.6 million during the year ended December 31, 2014 as compared to the eight months ended
December 31, 2013. The remaining increase of $8.0 million was primarily due to employee costs of $6.8 million related to our increased headcount and increases in equipment, rent and travel expenses of $0.9 million.

General and administrative expenses increased $11.9 million in the year ended December 31, 2014 compared to the
eight months ended December 31, 2013. Approximately $8.7 million of the increase is attributable to the extra four months of general and administrative during the year ended December 31, 2014 as compared to the eight months ended
December 31, 2013. The remaining increase was primarily due to an increase in employee costs of $8.0 million due to our increased headcount and increases in travel, rent and equipment expenses of $1.0 million. This increase was partially
offset by a legal settlement of $6.0 million, which was recorded during the eight months ended December 31, 2013.

Support subscription revenue increased $7.8 million in the eight months ended
December 31, 2013 compared to the same period in 2012. The increase was primarily due to an increase in revenue of $3.8 million from the July 2012 Microsoft contract, under which we began recognizing revenue on a ratable basis in October 2012,
and $1.1 million of net revenue ($1.5 million of gross revenue offset by $0.4 million of contra-revenue for the shares issued to an affiliate of AT&T, as described above) related to the AT&T contract, under which we began recognizing revenue
on a ratable basis in October 2013. The remaining increase was due to the growth of our customer base as well as sales of additional subscriptions to our existing customers.

Professional services revenue increased $5.3 million in the eight months ended December 31, 2013 compared to the same
period in 2012. The increase was primarily due to the growth of our customer base as well as sales of additional services to our existing customers.

Quarterly Trends in Revenue

Our quarterly revenue increased sequentially for seven of the eight quarters presented, primarily due to the increase in
support subscription customers each quarter as well as additional sales of support subscription and professional services to our existing customers. Revenue for the quarter ended December 31, 2014 decreased sequentially, as it included contra
revenue of $4.0 million related to the vesting of the 2011 Yahoo! Warrant upon our initial public offering in December 2014. Excluding the impact of said warrant, revenue for the quarter ended December 31, 2014 would have increased by $3.9
million compared to the prior quarters. The largest total contributor to quarterly revenue for the three months ended December 31, 2014, September 30, 2014, June 30, 2014, March 31, 2014 and December 31, 2013 was revenue
from Microsoft, comprising $2.5 million in each quarter in fiscal 2014 and $2.6 million of support subscription revenue for the quarter ended December 31, 2013.

Quarterly Operating Expenses Trends

Operating expenses are primarily driven by headcount and headcount-related expenses, including share-based compensation
expenses, and by sales and marketing initiatives. Our quarterly operating expenses generally increased sequentially for the eight quarters presented, primarily due to increase in headcount to support our growth. The three months ended
September 30, 2014 included a $4.0 million expense for the contribution of the developed technology from the XA Secure acquisition to the Apache Software Foundation. The three months ended June 30, 2013 included a legal settlement in
general and administrative expenses of $6.0 million. Refer to Note 4 and Note 6 in the notes to our consolidated financial statements for further discussion regarding the expense from the XA Secure acquisition and the nature of the legal settlement,
respectively.

Quarterly Gross Billings

We have included gross billings, a non-GAAP financial measure, in this annual report because it is a key measure used by our
board of directors and management to monitor our near term cash flows and manage our business. Gross billings is calculated as our total non-GAAP revenue, plus the change in deferred revenue for the same period. As we have not yet established
vendor-specific objective evidence of fair value for our support subscriptions, we recognize revenue ratably over the period beginning when both the support subscription and professional services have commenced for customers with agreements that
purchase both a support subscription and professional services. Most of our customer agreements include both support subscription and professional services. The accounting treatment for such agreements causes our revenue to trail the impact of these
customer agreements and creates significant deferred revenue balances.

We have provided a reconciliation between total
revenue, the most directly comparable GAAP financial measure, and gross billings in the table below. We believe gross billings provides useful information to investors and others in understanding and evaluating our operating results in the same
manner as our board of directors and management.

totaling $204.5 million, which were held for working capital purposes. Our cash equivalents are comprised primarily of money market funds. Our short-term investments are comprised primarily of commercial paper and corporate bonds.

The following table summarizes our cash flows for the periods indicated:

To date, we have financed our operations primarily through private placements of preferred
stock, our initial public offering and the concurrent private placement of our common stock, and cash flow from operations. We believe that our existing cash and cash equivalents balance, together with cash generated from sales of our support
subscriptions and professional services to customers and the $109.6 million (net of issuance costs) raised in our initial public offering and the concurrent private placement in December 2014, will be sufficient to meet our working capital and
capital expenditure requirements for at least the next 12 months.

Our expected future capital requirements may depend on
many factors including customer retention and expansion, the timing and extent of spending on platform development efforts, the expansion of sales, marketing and product management activities and ongoing investments to support the growth of our
business in the United States and internationally. We may in the future enter into arrangements to acquire or invest in complementary businesses, services and technologies and intellectual property rights. We may be required to seek additional
equity or debt financing in order to meet these future capital requirements. In the event that additional financing is required from outside sources, we may not be able to raise it on terms that are acceptable to us or at all. If we are unable to
raise additional capital when desired, our business, results of operations and financial condition would be adversely affected.

Operating
Activities

Our largest source of operating cash inflows is from sales of our support subscriptions and
professional services. Our primary uses of cash from operating activities are for personnel costs, which are allocated across cost of sales, sales and marketing, research and development and general and administrative costs.

Operating activities for the year ended December 31, 2014 used $87.9 million of cash compared to $29.8 million
for the eight months ended December 31, 2013. The increase was primarily driven by our net loss of $177.4 million, adjusted for the non-cash charges of $54.0 million associated with equity instruments issued to Yahoo! and an affiliate of
AT&T, and other non-cash items, for the year ended December 31, 2014 compared to a net loss of $46.2 million for the eight months ended December 31, 2013. In addition, accounts receivable increased by $20.2 million during the year
ended December 31, 2014 based on the timing of payments received from customers and the significant growth of our support subscription customer base. These factors were partially offset by an increase in deferred revenue of $35.0 million for
the year ended December 31, 2014 due to the increase in our support subscription customer base coupled with our ratable revenue recognition as a result of our lack of VSOE for support subscription revenue.

Operating activities for the eight months ended December 31, 2013 used $29.8 million of cash compared to $15.2 million
for the eight months ended December 31, 2012. The increase was primarily driven by our net loss of $46.2 million for the eight months ended December 31, 2013 compared to a net loss of $19.7 million for the

eight months ended December 31, 2012. Additionally, accounts receivable increased by $5.7 million during the eight months ended December 31, 2013 based on the timing of payments
received from customers and the significant growth of our subscription customer base. These factors were partially offset by an increase in deferred revenue of $11.2 million for the eight months ended December 31, 2013 due to the increase
in our support subscription customer base compared to the prior period coupled with our ratable revenue recognition as a result of our lack of VSOE for support subscription revenue.

Operating activities for the year ended April 30, 2013 used $32.0 million of cash compared to $0.9 million for the year
ended April 30, 2012. The increase was primarily driven by our net loss of $36.6 million for the year ended April 30, 2013 compared to a net loss of $11.5 million for the year ended April 30, 2012. In addition, accounts receivable
increased by $5.9 million for the year ended April 30, 2013 based on the timing of payments received from customers and the significant growth of our support subscription customer base compared to the prior year. These factors were partially
offset by an increase in deferred revenue of $6.6 million for the year ended April 30, 2013 due to the increase in our support subscription customer base compared to the prior period coupled with our ratable revenue recognition as a result
of our lack of VSOE for support subscription revenue.

Investing Activities

Investing activities for the year ended December 31, 2014 used $72.8 million of cash compared to $3.9 million for the
eight months ended December 31, 2013. The increase in cash used was primarily driven by an increase in purchases of investments of $74.2 million for the year ended December 31, 2014 compared to the eight months ended December 31,
2013. This was partially offset by an increase in maturity of investments of $16.4 million for the year ended December 31, 2014 compared to the eight months ended December 31, 2013.

Investing activities for the eight months ended December 31, 2013 used $3.9 million of cash compared to cash provided by
investing activities of $7.0 million for the eight months ended December 31, 2012. The decrease was primarily driven by an $11.3 million decrease in the maturity of short-term investments for the period ended December 31, 2013 compared to
the prior period.

Investing activities for the year ended April 30, 2013 generated $13.2 million of cash compared to
$25.6 million used for the year ended April 30, 2012. The increase was primarily driven by an $11.5 million decrease in investments purchased and $27.9 million in proceeds from the sale and maturity of investments compared to the prior
year.

Financing Activities

Financing activities for the year ended December 31, 2014 generated $264.4 million of cash compared to
$50.3 million for the eight months ended December 31, 2013. The increase was primarily driven by sale of our Series D preferred stock and our initial public offering, including the concurrent private placement, which generated net proceeds
of $149.5 million and $110.4 million, respectively, during the year ended December 31, 2014.

Financing
activities for the eight months ended December 31, 2013 generated $50.3 million of cash compared to $43 thousand for the eight months ended December 31, 2012. The increase was primarily driven by sale of the Series C preferred stock of
$49.8 million during the period ended December 31, 2013.

Financing activities for the year ended April 30, 2013
generated $0.1 million of cash compared to $53.8 million for the year ended April 30, 2012. The decrease was primarily driven by the $53.0 million issuance of preferred stock in the prior year.

Deferred Revenue and Backlog

Our deferred revenue, which consists of billed but unrecognized revenue, was $62.9 million as of December 31, 2014.

Our total backlog, which we define as including both cancellable and non-cancellable portions of our customer agreements
that we have not yet billed, was $15.3 million as of December 31, 2014. The timing of our invoices to our customers is a negotiated term and thus varies among our support subscription agreements. For multiple-year agreements, it is common
for us to invoice an initial amount at contract signing followed by subsequent annual invoices. At any point in the contract term, there can be amounts that we have not yet been contractually able to invoice. Until such time as these amounts are
invoiced, we do not recognize them as revenue, deferred revenue or elsewhere in our consolidated financial statements. The change in backlog that results from changes in the average non-cancelable term of our support subscription arrangements may
not be an indicator of the likelihood of renewal or expected future revenue, and therefore we do not utilize backlog as a key management metric internally and do not believe that it is a meaningful measurement of our future revenue.

Contractual Obligations and Other Commitments

The following table summarizes our contractual obligations as of December 31, 2014:

Off-Balance
Sheet Arrangements

Through December 31, 2014, we did not have any relationships with unconsolidated organizations
or financial partnerships, such as structured finance or special purpose entities that would have been established for the purpose of facilitating off-balance sheet arrangements or other contractually narrow or limited purposes.

Critical Accounting Policies and Estimates

We prepare our consolidated financial statements in accordance with GAAP. In the preparation of these consolidated financial
statements, we are required to make estimates and assumptions that affect the reported amounts of assets, liabilities, revenue, costs and expenses and related disclosures. To the extent that there are material differences between these estimates and
actual results, our financial condition or operating results would be affected. We base our estimates on past experience and other assumptions that we believe are reasonable under the circumstances, and we evaluate these estimates on an ongoing
basis. We refer to accounting estimates of this type as critical accounting policies and estimates, which we discuss below.

Revenue Recognition

Apache Hadoop is a freely available open source based software platform. While it has emerged as an enabling
technology for the modern data center architecture, there are limitations related to the traditional Hadoop offering that may inhibit broad adoption by enterprises. Our software development efforts are thus focused on creating an enterprise-grade
Hadoop platform by working in concert with the Apache community to develop the Hortonworks Data Platform (HDP).

##### Table of Contents

##### Index to Financial Statements

HDP is available under an Apache open source license. Open source software is an
alternative to proprietary software and represents a different model for the development and licensing of commercial software code than that typically used for proprietary software. Because open source software code is generally freely shared, we
typically do not generate any direct revenue from our software development activities.

We generate the predominant amount
of our revenue through support (support subscription) and consulting and training services (professional services) arrangements with our enterprise customers. We provide telephone support, security updates, bug fixes, functionality enhancements and
upgrades to the technology and new versions of the software, if and when available. Our professional services provide assistance in the implementation process and training related activities.

Under our support subscription and professional services arrangements, revenue is recognized when (i) persuasive evidence
of an arrangement exists; (ii) the services have been delivered; (iii) the arrangement fee is fixed or determinable; and (iv) collectability is reasonably assured.

Support subscription revenue

In single-element arrangements, support subscription fees are recognized on a ratable basis over the support subscription term.
Our support subscription arrangements do not contain refund provisions for fees earned related to services performed.

Professional services revenue

Professional services revenue is derived from customer fees for consulting services engagements and training
services. Our consulting services are provided primarily on a time and materials basis and, to a lesser extent, a fixed fee basis, and training services are priced based on attendance. Revenue from professional services, when such services are sold
in single-element arrangements, is recognized as the services are performed.

Multiple-element arrangements

Our multiple-element arrangements include support subscription combined with professional services. We have not yet established
vendor-specific objective evidence of fair value (VSOE) for our support subscription offerings, and we recognize revenue on a ratable basis over the period beginning when both the support subscription and professional services have commenced, and
ending at the conclusion of the support subscription or professional services period, whichever is longer. Under our multiple element arrangements, the support subscription element generally has the longest service period and the professional
services element is performed during the earlier part of the support subscription period.

Our agreements with customers
often include multiple support subscription and/or professional service elements, and these elements are sometimes included in separate contracts. We consider an entire customer arrangement to determine if separate contracts should be considered
linked arrangements for the purposes of revenue recognition.

Revenue recognition requires judgment, including whether a
software arrangement includes multiple elements and, if so, whether VSOE exists for those elements. A portion of revenue may be recorded as unearned due to undelivered elements. Changes to the elements in a software arrangement, the ability to
identify the VSOE for those elements and the fair value of the respective elements could materially impact the amount of earned and unearned revenue in a given period.

Revenue from Strategic Relationships and Reseller Arrangements

We have strategic relationships and reseller arrangements with third parties whereby our support subscription is bundled with
those third parties products and services. Under these arrangements, we are not the

##### Table of Contents

##### Index to Financial Statements

primary obligor for what is ultimately sold by the third parties to their end customers. The amount recognized as revenue represents the amount due to us from the third parties and is generally
recognized on a ratable basis over the applicable services term.

Equity instruments issued to customers

We have entered into warrant and share purchase agreements with certain customers. For such arrangements, the fair value of the
underlying securities is recognized as contra-revenue to the extent cumulative revenue from the customer is available to offset the fair value of the security on the measurement date. If cumulative revenue from the customer is less than the fair
value of the security, the excess is recorded as cost of sales. See additional discussion at Notes 8 and 15 to our consolidated financial statements for further discussion.

Stock-Based Compensation

We recognize compensation costs related to stock options granted to employees based on the estimated fair value of the awards
on the date of grant, net of estimated forfeitures. We estimate the grant date fair value, and the resulting stock-based compensation expense, using the Black-Scholes option-pricing model. The grant date fair value of the stock-based awards is
recognized on a straight-line basis over the requisite service period, which is the vesting period of the respective awards.

The Black-Scholes option-pricing model requires the use of highly subjective and complex assumptions, including the expected
term and the price volatility of the underlying stock, which determine the fair value of stock-based awards. These assumptions include:



| |  |  | Expected term. We estimate the expected term for stock options using the simplified method due to the lack of historical exercise
activity for us. The simplified method calculates the expected term as the midpoint between the vesting date and the contractual expiration date of the award.
| | - |  | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | Expected volatility. Since we do not have a trading history of our common stock, the expected volatility was derived from the average
historical stock volatilities of several unrelated public companies within our industry that we consider to be comparable to our business over a period equivalent to the expected term of the stock option grants.
| | - |  | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | Risk-free interest rate. The risk-free interest rate is based on the U.S. Treasury yield curve in effect at the time of grant for the
expected term of the stock-based award.
| | - |  | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | Expected dividend. The expected dividend is assumed to be zero as we have never paid dividends and have no current plans to pay any
dividends on our common stock.
| | - |  | ------------------------------------------------------------------------------------------------------------------------------------------------------------------

In addition to the assumptions used in the Black-Scholes option-pricing
model, we must also estimate a forfeiture rate to calculate the stock-based compensation for our awards. Our forfeiture rate is based on an analysis of our actual forfeitures. We will continue to evaluate the appropriateness of the forfeiture rate
based on actual forfeiture experience, analysis of employee turnover, and other factors. Quarterly changes in the estimated forfeiture rate can have a significant impact on our stock-based compensation expense as the cumulative effect of adjusting
the rate is recognized in the period the forfeiture estimate is changed. If a revised forfeiture rate is higher than the previously estimated forfeiture rate, an adjustment is made that will result in a decrease to the stock-based compensation
expense recognized in our financial statements. If a revised forfeiture rate is lower than the previously estimated forfeiture rate, an adjustment is made that will result in an increase to the stock-based compensation expense recognized in our
financial statements.

We will continue to use judgment in evaluating the expected volatility, expected terms and
forfeiture rates utilized for our stock-based compensation calculations on a prospective basis. As we continue to accumulate additional data related to our common stock, we may have refinements to the estimates of our expected volatility, expected
terms and forfeiture rates, which could impact our future stock-based compensation expense.

The determination of the grant date fair value of options using an option-pricing
model is affected by our estimated common stock fair value, as well as assumptions regarding a number of other complex and subjective variables. Historically, for all periods prior to our initial public offering, the fair values of the shares of
common stock underlying our share-based awards were estimated on each grant date by our board of directors. In order to determine the fair value of our common stock underlying option grants, our board of directors considered, among other things,
contemporaneous valuations of our common stock prepared by an unrelated third-party valuation firm in accordance with the guidance provided by the American Institute of Certified Public Accountants Practice Guide,Valuation of
Privately-Held-Company Equity Securities Issued as Compensation. Given the absence of a public trading market of our common stock, our board of directors exercised reasonable judgment and considered a number of other objective and subjective
factors to determine the best estimate of the fair value of our common stock, including; issuances of preferred stock and the rights, preferences and privileges of our preferred stock relative to those of our common stock; and the likelihood of
achieving a liquidity event, such as an initial public offering or sale given prevailing market conditions.

In
determining a fair value for our common stock, we estimated the enterprise value of our business using the market approach. The market approach estimates the fair value of a company by applying market multiples of comparable publicly-traded
companies in the same industry or similar lines of business. The market multiples are based on key metrics implied by the enterprise values of comparable publicly-traded companies. The estimated enterprise value is then allocated to the common stock
using a combination of the Probability Weighted Expected Return and the Option Pricing Methods.

For valuations after the
completion of this offering, our board of directors will determine the fair value of each share of underlying common stock based on the closing price of our common stock on the NASDAQ Global Select Market, as reported on the date of grant.

Loss contingencies

We are subject to the possibility of various loss contingencies arising in the ordinary course of business. We consider the
likelihood of loss or impairment of an asset, or the incurrence of a liability, as well as our ability to reasonably estimate the amount of loss, in determining loss contingencies. An estimated loss contingency is accrued when it is probable that an
asset has been impaired or a liability has been incurred and the amount of loss can be reasonably estimated. If we determine that a loss is possible and the range of the loss can be reasonably determined, then we disclose the range of the possible
loss. We regularly evaluate current information available to us to determine whether an accrual is required, an accrual should be adjusted or a range of possible loss should be disclosed.

Recently Issued and Adopted Accounting Pronouncements

Under the JOBS Act, we meet the definition of an emerging growth company. We have irrevocably elected to opt out of
the extended transition period for complying with new or revised accounting standards pursuant to Section 107(b) of the JOBS Act.

On May 28, 2014, the FASB issued ASU No. 2014-09, Revenue from Contracts with Customers (Topic 606), which requires
an entity to recognize the amount of revenue to which it expects to be entitled for the transfer of promised goods or services to customers. The ASU will replace most existing revenue recognition guidance in U.S. GAAP when it becomes effective. The
new standard is effective for us on January 1, 2017. Early application is not permitted. The standard permits the use of either the retrospective or cumulative effect transition method. We are evaluating the effect that ASU 2014-09 will have on
our consolidated financial statements and related disclosures. We have not yet selected a transition method nor have we determined the effect of the standard on our ongoing financial reporting.

Item 7A. Quantitative and Qualitative Disclosures About Market Risk.

Interest Rate Risk

Our primary exposure to market risk relates to interest rate changes. We had cash and cash equivalents and short-term
investments totaling $204.5 million as of December 31, 2014. Cash and cash equivalents are comprised primarily of money market funds. Our short-term investments are primarily comprised of corporate bonds and commercial paper. The cash and
cash equivalents are held for working capital purposes. Our investments are made for capital preservation purposes. We do not enter into investments for trading or speculative purposes. Because of the short-term nature of the instruments in our
portfolio, a sudden change in market interest rates would not be expected to have a material impact on our consolidated financial statements. While not currently a risk, we may have long-term investments from time to time subject to interest rate
risk.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

To the Board of Directors and Stockholders of Hortonworks, Inc.

Santa Clara, California

We
have audited the accompanying consolidated balance sheets of Hortonworks, Inc. and subsidiaries (the Company) as of December 31, 2014, December 31, 2013, and April 30, 2013, and the related consolidated statements of
operations, comprehensive loss, convertible preferred stock and stockholders equity (deficit), and cash flows for the year ended December 31, 2014, eight months ended December 31, 2013, and each of the two years in the period ended
April 30, 2013. These consolidated financial statements are the responsibility of the Companys management. Our responsibility is to express an opinion on these consolidated financial statements based on our audits.

We conducted our audits in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards
require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement. The Company is not required to have, nor were we engaged to perform, an audit of its internal control
over financial reporting. Our audits included consideration of internal control over financial reporting as a basis for designing audit procedures that are appropriate in the circumstances, but not for the purpose of expressing an opinion on the
effectiveness of the Companys internal control over financial reporting. Accordingly, we express no such opinion. An audit also includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements,
assessing the accounting principles used and significant estimates made by management, as well as evaluating the overall financial statement presentation. We believe that our audits provide a reasonable basis for our opinion.

In our opinion, such consolidated financial statements present fairly, in all material respects, the consolidated financial position of the
Company as of December 31, 2014, December 31, 2013, and April 30, 2013, and the consolidated results of its operations and its cash flows for the year ended December 31, 2014, eight months ended December 31, 2013, and
each of the two years in the period ended April 30, 2013 in accordance with accounting principles generally accepted in the United States of America.

As discussed in Note 2 to the consolidated financial statements, the Company changed its fiscal year end from April 30 to
December 31.

Notes to Consolidated Financial Statements

1. ORGANIZATION AND DESCRIPTION OF BUSINESS

Hortonworks, Inc. (the Company) was incorporated in Delaware on April 15, 2011, and is focused on the
development, distribution and support of the Hadoop open source project from the Apache Software Foundation (Apache Hadoop or Hadoop). Hadoop is a registered trademark of the Apache Software Foundation. Hadoop was originally developed in
the early 2000s. Partnering with the Apache Hadoop community, Yahoo! led major innovations in the technology to help tackle big data challenges and operate its business at scale. Hadoop is managed as an open source software project by the Apache
Foundation.

Due to the increase in the volume of data and the variety of data, including new unstructured data types such
as clickstream data, geo-location data, sensor and machine data, sentiment data, server log data and other data generated by emails, documents and other file types, Hadoop has emerged as a critical enabling technology for the modern data center
architecture. The Companys software development efforts are thus focused on creating an enterprise-grade Hadoop platform by working in concert with the Apache community to develop the Hortonworks Data Platform.

In December 2014, the Company completed its initial public offering and concurrent private placement (collectively, the
IPO) of 7,673,986 shares of common stock (inclusive of 486,486 shares in a concurrent private placement and 937,500 shares of common stock from the full exercise of the over-allotment option granted to the underwriters) at a price
of $16.00 per share. The Company received net cash proceeds of $109.6 million from the sale of shares of common stock. Immediately prior to the closing of the IPO, all shares of the Companys outstanding convertible
preferred stock automatically converted into 21,949,525 shares of common stock.

2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

Principles of Consolidation

The consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the
United States of America (U.S. GAAP) and include the accounts of the Company and its wholly owned subsidiaries. All intercompany transactions and balances have been eliminated in consolidation.

Change of Fiscal Year End

The Company changed its fiscal year end from April 30 to December 31. Unless otherwise noted, all references to
years in this report refer to the twelve-month fiscal year, which prior to May 1, 2013 ended on April 30, and beginning with January 1, 2014 ends on December 31 of each year. These financial statements include the
audited transition period of May 1, 2013 through December 31, 2013. The consolidated statement of operations, consolidated statement of comprehensive loss and consolidated statement of cash flows for the eight months ended
December 31, 2012 have been presented for comparative purposes and are unaudited.

Use of Estimates

The preparation of consolidated financial statements in conformity with U.S. GAAP requires management to make estimates and
assumptions that affect the reported amounts of assets and liabilities, disclosure of contingent assets and liabilities at the date of the consolidated financial statements, and the reported amounts of expenses during the reporting period. The
Company bases its estimates and judgments on its historical experience, knowledge of current conditions, and its beliefs on what could occur in the future given available information. Estimates, assumptions and judgments are used for, but are not
limited to, revenue recognition, stock-based awards and warrants, accounting for income taxes, allowance for doubtful accounts and certain accrued liabilities.

Notes to Consolidated Financial Statements



Concentration of Risk

Credit Risk

Financial instruments, which potentially subject the Company to concentration of credit risk, consist primarily of cash and
cash equivalents and short term investments. The Company places its cash and cash equivalents with major financial institutions, which management assesses to be of high-credit quality.

The Companys investment policies limit investments to those that are investment grade, liquid securities, and restricts
placement of these investments to issuers evaluated as creditworthy.

Concentration of Revenue and Accounts Receivable

The Company generally does not require collateral or other security in support of accounts receivable. Allowances are provided
for individual accounts receivable when the Company becomes aware of a customers inability to meet its financial obligations, such as in the case of bankruptcy, deterioration in the customers operating results or change in financial
position. If circumstances related to customers change, estimates of the recoverability of receivables would be further adjusted. The Company also considers broad factors in evaluating the sufficiency of its allowances for doubtful accounts,
including the length of time receivables are past due, significant one-time events, creditworthiness of customers and historical experience.

Significant customers are those which represent 10% or more of the Companys total revenue or gross accounts receivable
balance at each respective balance sheet date. For each significant customer, revenue as a percentage of total revenue and accounts receivable as a percentage of total net accounts receivable are as follows:

Cash and Cash
Equivalents

Cash and cash equivalents consist of cash and money market funds with original maturities of three
months or less at the time of purchase.

Investments

The Company classifies its debt securities as trading, available for sale or
held-to-maturity, depending on managements intent at the time of purchase. Unrealized losses on available-for-sale securities are charged against net earnings when a decline in fair value is determined to be other than temporary.
The Companys management reviews several factors to determine whether a loss is other than temporary, such as the length and extent of the fair value decline, the financial condition and near term prospects of the issuer, and for equity
investments, the Companys intent and ability to hold the security for a period of time sufficient to allow

for any anticipated recovery in fair value. For debt securities, management also evaluates whether the Company has the intent to sell or will likely be required to sell before its anticipated
recovery. Realized gains and losses are accounted for on the specific identification method.

Available-for-sale debt
instruments with original maturities at the date of purchase greater than approximately three months and remaining maturities of less than one year are classified as short-term investments. Available-for-sale debt instruments with remaining
maturities beyond one year are classified as long-term investments.

Fair Value Measurement

Fair value is defined as the price that would be received to sell an asset or paid to transfer a liability in the principal
market (or most advantageous market, in the absence of a principal market) for the asset or liability in an orderly transaction between market participants at the measurement date. Further, entities are required to maximize the use of observable
inputs and minimize the use of unobservable inputs in measuring fair value, and to utilize a three-level fair value hierarchy that prioritizes the inputs used to measure fair value. The three levels of inputs used to measure fair value are as
follows:

Level 1Quoted prices in active markets for identical assets or liabilities.

Level 2Observable inputs other than quoted prices included within Level 1, including quoted prices for similar assets
or liabilities in active markets; quoted prices for identical or similar assets or liabilities in markets that are not active; and inputs other than quoted prices that are observable or are derived principally from, or corroborated by, observable
market data by correlation or other means.

Level 3Unobservable inputs that are supported by little or no market
activity, are significant to the fair value of the assets or liabilities, and reflect the Companys own assumptions about the assumptions market participants would use in pricing the asset or liability developed based on the best information
available in the circumstances.

Restricted Cash

Restricted cash includes collateral used to secure a credit card, and may not be used or transferred until the restriction is
released by the issuing bank. Restricted cash also includes deposits made on office space, and may be refundable in full or in part at the end of the respective lease terms.

Software Development Costs

The Company develops open source software that is generally freely available on the Apache Hadoop platform. Capitalization of
software development costs begins upon the establishment of technological feasibility and ceases when the product is available for general release. As a result of the Companys practice of developing open source software that is generally
freely available, there is generally no passage of time between the achievement of technological feasibility and the availability of the Companys software for general release. The Company does not have any internally-developed software.
Therefore, the Company has no capitalized software development costs at December 31, 2014, December 31, 2013, and April 30, 2013.

Property and Equipment

Property and equipment are stated at cost. Depreciation is computed using a straight-line method over the estimated useful
lives, determined to be two years for purchased software, two to three years for computer



72

equipment, and five years for network and communication equipment and furniture and fixtures. Expenditures for repairs and maintenance are charged to expenses as incurred. Leasehold improvements
and capital leases are amortized on a straight-line basis over the term of the lease, or the useful life of the assets, whichever is shorter.

Goodwill and Long-Lived Assets

Goodwill is tested for impairment on an annual basis and between annual tests if events or circumstances indicate that an
impairment loss may have occurred. The test is based on a comparison of the reporting units book value to its estimated fair market value. The annual impairment test is performed by the Company during the fourth quarter of each fiscal year
using the opening balance sheet as of the first day of the fourth quarter, with any resulting impairment recorded in the fourth quarter of the fiscal year. During the year ended December 31, 2014, the Company determined that the fair value of
its sole reporting unit exceeded its carrying value, and as a result, no goodwill impairment was recorded in fiscal 2014.

Long-lived assets are reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount of
such assets may not be recoverable. In such instances, the recoverability of assets to be held and used is measured first by a comparison of the carrying amount of an asset group to future undiscounted net cash flows expected to be generated by the
asset. If such assets are considered to be impaired, an impairment loss would be recognized if the carrying amount of the asset exceeds the fair value of the asset. To date, the Company believes that no such impairment has occurred.

Common Stock Warrant Liability

Warrants for common stock that did not meet the requirements for equity classification because the number of shares were
variable based on future issuances of Series D preferred shares or warrants were previously classified as liabilities on the accompanying balance sheets and carried at their estimated fair value. At the end of each reporting period, any changes in
fair value were recorded as a component of other expense until the consummation of the Companys initial public offering in December 2014. Upon the consummation of the initial public offering, the warrants were reclassified to additional
paid-in capital within stockholders equity, as the requirements for equity classification were met.

Revenue Recognition

Apache Hadoop is a freely available open source based software platform. While it has emerged as an enabling technology for the
modern data center architecture, there are limitations related to the traditional Hadoop offering that may inhibit broad adoption by enterprises. The Companys software development efforts are thus focused on creating an enterprise-grade Hadoop
platform by working in concert with the Apache community to develop the Hortonworks Data Platform (HDP).

HDP is available
under an Apache open source license. Open source software is an alternative to proprietary software and represents a different model for the development and licensing of commercial software code than that typically used for proprietary software.
Because open source software code is generally freely shared, the Company does not typically generate any direct revenue from its software development activities.

The Company generates the predominant amount of its revenue through support (support subscription) and consulting and training
services (professional services) arrangements with its enterprise customers. The Company provides telephone support, security updates, bug fixes, functionality enhancements and upgrades to the technology and new versions of the software, if and when
available. The Companys professional services provide assistance in the implementation process and training related activities.

Under the Companys support subscription and professional services
arrangements, revenue is recognized when (i) persuasive evidence of an arrangement exists; (ii) the services have been delivered; (iii) the arrangement fee is fixed or determinable; and (iv) collectability is reasonably assured.

Support subscription revenue

In single-element arrangements, support subscription fees are recognized on a ratable basis over the support subscription term.
The Companys support subscription arrangements do not contain refund provisions for fees earned related to support services performed.

Professional services revenue

Professional services revenue is derived from customer fees for consulting services engagements and training services. The
Companys consulting services are provided primarily on a time and materials basis and, to a lesser extent, a fixed fee basis, and training services are priced based on attendance. Revenue from professional services, when such services are sold
in single-element arrangements, is recognized as the services are performed.

Multiple-element arrangements

The Companys multiple-element arrangements include support subscription combined with professional services. The Company
has not yet established vendor-specific objective evidence of fair value (VSOE) for support subscriptions, and the Company recognizes revenue on a ratable basis over the period beginning when both the support subscription and professional services
have commenced, and ending at the conclusion of the support subscription or professional services period, whichever is longer. Under the Companys multiple element arrangements, the support subscription element generally has the longest service
period and the professional services element is performed during the earlier part of the support subscription period.

The
Companys agreements with customers often include multiple support subscription and/or professional service elements, and these elements are sometimes included in separate contracts. The Company considers an entire customer arrangement to
determine if separate contracts should be considered linked arrangements for the purposes of revenue recognition.

Revenue
recognition requires judgment, including whether a software arrangement includes multiple elements, and if so, whether VSOE exists for those elements. A portion of revenue may be recorded as unearned due to undelivered elements. Changes to the
elements in a software arrangement, the ability to identify the VSOE for those elements and the fair value of the respective elements could materially impact the amount of earned and unearned revenue in a given period.

Revenue from Strategic Relationships and Reseller Arrangements

The Company has strategic relationships and reseller arrangements with third parties (collectively Partners)
whereby the Companys support subscription is bundled with the Partners products and services. Under these arrangements, the Company is not the primary obligor for what is ultimately sold by the Partners to their end customers. The amount
recognized as revenue represents the amount due to the Company from the Partners and is generally recognized on a ratable basis over the applicable services term.

Equity instruments issued to customers

The Company has entered into warrant and share purchase agreements with certain customers. For such arrangements, the fair
value of the underlying securities is recognized as contra-revenue to the extent cumulative



74

revenue from the customer is available to offset the fair value of the security on the measurement date. If cumulative revenue from the customer is less than the fair value of the security, the
excess is recorded as cost of sales. See additional discussion at Notes 8 and 15.

Deferred Revenue

Deferred revenue consists of amounts billed to customers but not yet recognized in revenue.

As of December 31, 2014, December 31, 2013 and April 30, 2013, most of our accounts receivable represents
amounts billed to customers but not yet received or recognized as revenue and are thus recorded as deferred revenue.

Accounts Receivable and
Allowance for Doubtful Accounts

Accounts receivable are recorded at the invoiced amount, net of allowances for
doubtful accounts. The allowance for doubtful accounts is based on the assessment of the collectability of accounts. The Company regularly reviews the adequacy of the allowance for doubtful accounts by considering the age of each outstanding invoice
and the collection history of each customer to determine whether a specific allowance is appropriate. Accounts receivable deemed uncollectable are charged against the allowance for doubtful accounts when identified. For all periods presented, the
allowance for doubtful accounts activity was not significant.

Cost of Revenue

Cost of support subscription revenue consists primarily of personnel costs (including salaries, benefits and share-based
compensation) for employees associated with support subscription offerings primarily related to technology support and allocated shared costs. Cost of professional services revenue consists primarily of personnel costs (including salaries, benefits
and share-based compensation) for employees and subcontractors associated with service contracts, travel costs and allocated shared costs. The Company allocates shared costs such as rent, shared information technology costs and employee benefit
costs to all departments based on headcount. As such, allocated shared costs are reflected in cost of revenue and each operating expense category. Additionally, during the year ended December 31, 2014, cost of support subscription and
professional services revenue included expenses of $47.4 million and $0.6 million, respectively, related to the vesting of the 2011 Yahoo! Warrant upon the Companys initial public offering. Cost of revenue for support subscription and
professional services is expensed as incurred.

Sales and Marketing Expenses

Sales and marketing expenses consist of costs, including salaries, sales commissions and related expenses such as travel costs.
Sales and marketing expenses also include costs of advertising, online marketing, promotional events, corporate communications, product marketing, other brand-building activities, and allocated shared costs. All costs of advertising, including
cooperative marketing arrangements, are expensed as incurred. Advertising expense totaled, $7.2 million, $2.2 million, $1.1 million, $2.4 million and $0.7 million for the year ended December 31, 2014, eight months ended
December 31, 2013 and 2012 (unaudited) and years ended April 30, 2013 and 2012, respectively.

Research and Development Expenses

Research and development expenses include all direct costs, primarily salaries for Company personnel and outside
consultants, related to the development of new software products, significant enhancements to existing software products and allocated shared costs.

Stock-Based Compensation

The Company recognizes compensation costs related to stock options granted to employees based on the estimated fair value of
the awards on the date of grant, net of estimated forfeitures. The Company estimates the grant date fair value of option grants, and the resulting stock-based compensation expense, using the Black-Scholes option-pricing model. The grant date fair
value of stock-based awards is recognized on a straight-line basis over the requisite service period, which is the vesting period of the respective awards.

The Company accounts for stock options issued to non-employees based on the fair value of the awards determined using the
Black-Scholes option-pricing model. The fair value of stock options granted to non-employees are remeasured each period as the stock options vest, and the resulting change in value, if any, is recognized in the consolidated statements of operations
during the period the related services are performed.

Income Taxes

The Company accounts for income taxes using an asset and liability approach. Deferred income tax assets and liabilities are
computed for differences between the financial statement and income tax basis of assets and liabilities that will result in taxable or deductible amounts in the future. Such deferred income tax asset and liability computations are based on enacted
tax laws and rates applicable to periods in which the differences are expected to affect taxable income. A valuation allowance is established, when necessary, for any portion of deferred income tax assets where it is considered more likely than not
that it will not be realized.

The tax effects of the Companys income tax positions are recognized only if
determined more likely than not to be sustained based solely on the technical merits as of the reporting date. The Company considers many factors when evaluating and estimating its tax positions and tax benefits, which may require
periodic adjustments and which may not accurately anticipate actual outcomes.

Foreign Currency Translation

The impact of changes in foreign currency exchange rates resulting from the translation of foreign currency financial
statements into U.S. dollars for financial reporting purposes is included in other comprehensive loss. Assets and liabilities are translated into U.S. dollars at exchange rates in effect at the balance sheet date. Income and expense items are
translated at average rates for the period.

Foreign transaction gains and losses are recorded as they are realized, and
such amounts have historically been insignificant.

Net Loss Per Share of Common Stock

Basic net loss per share of common stock is calculated by dividing the net loss by the weighted-average number of common shares
outstanding during the period, less restricted common stock and common stock issued that is subject to repurchase, and excludes any dilutive effects of share-based awards. Diluted net loss per share of common stock is the same as basic net loss per
share of common stock, since the effects of potentially dilutive securities are antidilutive.

Recently Issued Accounting Pronouncements

In May 2014, the Financial Accounting Standards Board, or FASB, issued ASU No. 2014-09, Revenue from
Contracts with Customers (Topic 606), which requires an entity to recognize the amount of revenue to which it expects to be entitled for the transfer of promised goods or services to customers. The ASU will replace most existing revenue recognition
guidance in U.S. GAAP when it becomes effective. The new standard is effective

for the Company on January 1, 2017. Early application is not permitted. The standard permits the use of either the retrospective or cumulative effect transition method. The Company is
evaluating the effect that ASU 2014-09 will have on its consolidated financial statements and related disclosures. The Company has not yet selected a transition method nor has it determined the effect of the standard on its ongoing financial
reporting.

Where applicable, the Company uses quoted market prices in active markets for identical assets to determine fair value. This
pricing methodology applies to Level 1 investments, which are composed of money market funds.

If quoted prices in
active markets for identical assets are not available, then the Company uses quoted prices for similar assets or inputs other than quoted prices that are observable, either directly or indirectly. These

investments are included in Level 2 and consist of commercial paper, certificates of deposit and corporate bonds. Corporate bonds are valued at a consensus price, which is a weighted-average
price based on market prices from a variety of industry standard data providers used as inputs to a distribution-curve based algorithm. Commercial paper is valued using market prices if available, adjusting for accretion of the purchase price to
face value at maturity. The carrying amounts of accounts receivable, prepaid expenses, accounts payable, accrued liabilities and accrued compensation and benefits approximate fair value due to the short-term nature of these items.

A financial instruments categorization within the valuation hierarchy is based upon the lowest level of input that is
significant to the fair value measurement. The Companys assessment of the significance of a particular input to the fair value measurement in its entirety requires management to make judgments and consider factors specific to the asset or
liability.

In certain cases where there is limited activity or less transparency around inputs to valuation, securities
are classified as Level 3 within the valuation hierarchy. Level 3 liabilities that were measured at estimated fair value on a recurring basis consisted of the common stock warrant liability (see Note 9). The estimated fair value of the common stock
warrant liability was measured using a probability weighted expected return model. Inputs used to determine estimated fair value include the estimated fair value of the underlying common stock at the measurement date, the probability and timing of
various liquidity events, the exercise price per share, risk-free interest rates, and expected volatility of the price of the underlying common stock.

During the periods presented, the Company has not changed the manner in which it values liabilities that are measured at
estimated fair value using Level 3 inputs. There were no transfers within the hierarchy during the year ended December 31, 2014, the eight months ended December 31, 2013 and 2012, or the years ended April 30, 2013 and 2012.

The following table provides a summary of changes in the estimated fair value of the Companys liabilities measured at
estimated fair value using significant Level 3 inputs for the year ended December 31, 2014 (in thousands):

The above represents a warrant to purchase 476,368 of the Companys common stock as of
December 31, 2014 (see Note 9).

4. BUSINESS COMBINATIONS

On May 13, 2014, the Company acquired 100% of the voting shares of XA Secure, a developer of data security solutions
across a number of information technology platforms, for approximately $4.8 million, consisting of approximately $3.0 million in cash and the issuance of 132,508 shares of the Companys common stock with a fair value of $13.70 per
share on the acquisition date. The Company integrated the core security capabilities acquired across all Hadoop workloads. The acquisition of XA Secure was accounted for as the purchase of a business. The related acquisition costs, consisting
primarily of legal expenses in the amount of $0.2 million during the year ended December 31, 2014, were expensed. These legal expenses were presented as general and administrative expenses on the consolidated statements of operations for
the year ended December 31, 2014.

The acquisition of XA Secure provided the Company with developed technology.
The Company determined that the fair value of the developed technology was approximately $4.0 million. The fair value of the developed technology was determined using the cost approach. The cost approach reflects the amount that would be required
currently (at the acquisition date) to replace the service capacity of an asset. The assumptions underlying the fair value calculation include: the labor required using a burdened overhead rate, the development period, a developers profit
based on the operating profitability of market participants, and the opportunity cost based on the estimated required return on investment over the development period using venture capital rates of return and private capital rates of return for
enterprises at a similar stage of development as XA Secure. A deferred tax liability related to the fair value of the developed technology obtained in the acquisition was also recognized. Primarily as a result of the deferred tax liability
recognized in the acquisition, the Company recognized goodwill of $2.1 million equal to the excess of the purchase consideration over the fair value of the assets acquired and the liabilities assumed. None of the goodwill is expected to be
deductible for income tax purposes.

Concurrently with the recognition of the deferred tax liability related to the
developed technology acquired, the Company released a portion of the valuation allowance on its deferred tax asset balance and recognized a $1.3 million benefit to income tax expense. The benefit for income taxes resulted from the additional source
of income arising from the deferred tax liability recognized, which offset the Companys deferred tax assets. As such, the impact on the acquiring Companys deferred tax assets and liabilities caused by an acquisition are recorded in the
acquiring Companys consolidated financial statements outside of acquisition accounting.

In connection with the
acquisition of XA Secure, the Company also issued 132,506 shares of restricted stock, issued 159,483 options to purchase the Companys common stock and may be required to pay an additional $3.92 million to certain key employee-shareholders of
XA Secure. Fifty percent of the restricted shares vest at the 12-month anniversary of the acquisition and the remaining 50% vest at the 18-month anniversary. Twenty-five percent of the options vest at the 12-month anniversary of the acquisition and
the remaining 75% vest ratably over the next 36 months. Fifty percent of the contingent cash payment will be made at the 12-month anniversary of the acquisition and the remaining contingent cash payment will be made at the 18-month anniversary. All
vesting provisions for the stock and options, as well as the future cash payments, are contingent upon the continued service of the key employees. Thus, the Company will account for such payments as post-combination remuneration, recognized in
operating expenses in the statement of operations as the services are performed.

The following table summarizes the
allocation of the consideration paid of approximately $4.8 million to the fair values of the assets acquired and liabilities assumed at the acquisition date (in thousands):



|                         |  |        |        |  
|------------------------ |  | ------ | ------ | -
|                         |  | Amount |

|Deferred tax liabilities |  |        | (1,279 | )
|Goodwill                 |  |        | 2,119  |  
|Net assets acquired      |  | $      | 4,811  |  

The results of operations of XA Secure have been included in the Companys consolidated
statements of operations from the acquisition date. Pro forma results of operations have not been presented because the acquisition was not material to the Companys results of operations.

Goodwill and Intangible Assets.

Intangible assets acquired in connection with the acquisition of XA Secure were comprised entirely of developed technology of
$4.0 million. On August 13, 2014, the Company contributed the developed technology

acquired in the XA Secure acquisition to the Apache Software Foundation. Upon contribution, the Company recognized an expense of $4.0 million within operating expenses, which was equal to
the carrying value of the developed technology.

Notes to Consolidated Financial Statements



In November 2012, the Company entered into a three-year master lease
agreement that provides the Company with the right, but not the obligation, to lease up to $3.0 million of data center equipment from a third-party vendor. As of December 31, 2014, the Company has leased $2.2 million of data center
equipment under this agreement. Future minimum payments due under these operating leases are included in the table above.

Litigation settlement

In November 2013, the Company agreed to settle a lawsuit for $6.0 million, which was included in general and
administrative operating expenses in the consolidated statement of operations for the eight months ended December 31, 2013. A $1.0 million settlement payment was made in November 2013, with the remaining $5.0 million due in November 2014
and included as an accrued liability on the consolidated balance sheet as of December 31, 2013. The amount was paid in full in November 2014. The lawsuit arose from the decisions by certain of the Companys employees to leave their former
employer and join the Company at various times during 2011 and 2012. Their former employer alleged that in connection with these departures, some of the individual defendants misappropriated trade secrets by retaining certain files and documents,
and breached non-solicitation obligations. The former employer alleged that the Company was liable for the conduct of the individual defendants. The matter was dismissed with prejudice in November 2013.

In addition, from time to time, the Company is party to various litigation and administrative proceedings relating to claims
arising from its operations in the normal course of business. Based on the information presently available, including discussion with legal counsel, management believes that resolution of these matters will not have a material effect on the
Companys business, results of operations, financial condition or cash flows.

8. PREFERRED STOCK WARRANT (2011 YAHOO! WARRANT)

In July 2011, the Company issued a warrant to purchase 6,500,000 shares of Series A preferred stock at an exercise price
of $0.005 per share (which converted into a warrant to purchase 3,250,000 shares of common stock). The warrant was issued to Yahoo! in connection with the Companys Series A financing and the transactions contemplated thereby, including
commercial agreements with Yahoo! providing for support subscription offerings and certain rights to technology. The ability for Yahoo! to exercise the warrant was subject to the continuation of the commercial agreement for a period of two years,
which has been satisfied. The warrant expires nine years from the date of issuance. Upon the consummation of the Companys initial public offering in December 2014, the preferred stock warrant became exercisable and automatically converted into
a common stock warrant. As the warrant was issued to a customer, upon the occurrence of the initial public offering, the vesting of the warrant resulted in an immediate $4.0 million reduction in revenue, which was the cumulative revenue from Yahoo!.
The $48.0 million difference between the fair value of the warrant of $52.0 million and the reduction in revenue was recognized in cost of revenue during the fourth quarter of the current year. The $52.0 million fair value of the warrant was
recognized in additional paid-in capital. Refer to Note 15 for additional information regarding related party transactions.

9. COMMON STOCK
WARRANT

On June 9, 2014, the Company issued a warrant to purchase a number of shares of common stock up
to 1% of the sum of (i) 45,585,496, plus (ii) the number of shares of Series D preferred stock or shares of such stock issuable upon exercise of warrants to purchase such stock (on an as converted to common stock basis) issued or
issuable upon exercise of warrants to purchase Series D Preferred Stock that are sold, if any, by the Company during the period commencing on June 9, 2014 and ending immediately prior to the occurrence of a corporate event at an
exercise price of $8.46 per share. The warrant was issued to Yahoo! in exchange for the amendment of the rights held by Yahoo! under Section 2.11 of the Investors Rights Agreement to approve an acquisition of Hortonworks, which
removed a competitor of Yahoo! from the list of companies over which Yahoo! has such blocking rights. The warrant expires nine years from the date of issuance. The warrant vested upon the consummation of the Companys initial public offering in
December 2014. The combined value of the initial

measurement and the change in the fair value of this warrant of $5.4 million is recorded as other expense in the consolidated statement of operations for the year ended December 31,
2014. Upon the initial public offering, the common stock warrant liability was reclassified to additional paid-in capital at the then current fair value of $5.4 million (see discussion in Note 3).

10. STOCK OPTION PLAN

2011 Stock Option Plan

In June 2011, the Company adopted the Hortonworks, Inc. 2011 Stock Option and Grant Plan (the 2011
Plan). The 2011 Plan allows for grant of incentive stock options (ISOs), nonstatutory stock options (NSOs), restricted common stock and restricted stock units to employees, officers, directors and consultants of the
Company. The exercise price of an option is determined by the Board of Directors when the option is granted, and may not be less than 100% of the fair market value of the shares on the date of grant, provided that the exercise price of ISOs granted
to a 10% stockholder is not less than 110% of the fair market value of the shares on the date of grant. ISOs granted under the 2011 Plan generally vest 25% after the completion of 12 months of service and the balance in equal monthly
installments over the next 36 months of service, and expire 10 years from the date of grant. ISOs granted to a 10% stockholder expire five years from the date of grant. NSOs vest according to the specific option agreement, and expire
10 years from the date of grant.

In December 2014, in connection with the closing of the Companys initial
public offering, the 2011 Plan was terminated and shares authorized for issuance under the 2011 Plan were cancelled (except for those shares reserved for issuance upon exercise of outstanding stock options). As of December 31, 2014, options to
purchase 13,605,044 shares of common stock were outstanding under the 2011 Plan pursuant to their original terms and no shares were available for future grant.

2014 Stock Option and Incentive Plan

The Companys 2014 Stock Option and Incentive Plan, or the 2014 Plan, was adopted by the Companys board of directors
in September 2014, was approved by the Companys stockholders in November 2014 and became effective immediately prior to the closing of the Companys initial public offering. The 2014 Plan will be used going forward instead of the 2011
Plan as the Companys board of directors has determined not to make additional awards under that plan following the consummation of the initial public offering. The 2014 Plan allows the compensation committee to make equity-based incentive
awards to the Companys officers, employees, directors and other key persons (including consultants).

The Company
has initially reserved 6,000,000 shares of the Companys common stock for the issuance of awards under the 2014 Plan, plus the shares of the Companys common stock remaining available for issuance under the Companys 2011 Plan. The
2014 Plan provides that the number of shares reserved and available for issuance under the plan will automatically increase each January 1, beginning on January 1, 2015, by 5% of the outstanding number of shares of the Companys
common stock on the immediately preceding December 31 or such lesser number of shares as determined by the Companys compensation committee. This number is subject to adjustment in the event of a stock split, stock dividend or other change
in the Companys capitalization. As of December 31, 2014, options to purchase and restricted stock units to convert to a total of 405,100 shares of common stock were outstanding under the 2014 Plan pursuant to their original terms.

As of December 31, 2014, an aggregate of 6,923,732 shares were reserved under the 2014 Plan, of which
6,518,632 shares remained available for issuance.

The fair value of each grant of stock options was determined using the Black-Scholes
option-pricing model and assumptions discussed below. Each of these inputs is subjective and generally requires significant judgment to determine.

Fair Value of Common Stock. Historically, for all periods prior to the Companys initial public offering, the
Company estimated the fair value of common stock. The fair value of the common stock underlying the stock-based awards was determined by the Companys board of directors, which considered numerous objective and subjective factors to determine
the fair value of common stock at each grant date. These factors included, but were not limited to: (i) contemporaneous valuations of common stock performed by third-party specialists; (ii) the lack of marketability of the Companys
common stock; (iii) developments in the business; (iv) the prices paid in recent transactions involving the Companys equity securities; and (v) the likelihood of achieving a liquidity event, such as an initial public offering or
a merger or acquisition, given prevailing market conditions.

Since the Companys initial public offering, it has
used the market closing price of its common stock as reported on the NASDAQ Global Select Market.

Expected Term. The Company estimates the expected term for stock
options using the simplified method due to the lack of historical exercise activity for the Company. The simplified method calculates the expected term as the mid-point between the vesting date and the contractual expiration date of the award.

Expected Volatility. Since the Company does not have a trading history of its common stock, the expected
volatility was derived from the average historical stock volatilities of several unrelated public companies within the Companys industry that it considers to be comparable to its business over a period equivalent to the expected term of the
stock option grants.

Risk-Free Interest Rate. The risk-free interest rate is based on the U.S. Treasury yield
curve in effect at the time of grant for the expected term of the stock-based award.

Dividend Rate. The
expected dividend yield is zero, as the Company does not currently pay a dividend and does not expect to do so in the foreseeable future.

Forfeiture Rate. Forfeitures are estimated based on the Companys analysis of historical stock option
forfeitures. To the extent that the forfeiture rate is different than what the Company has estimated, the compensation cost associated with unrecognized stock compensation expense will be different from Company expectations.

Restricted Stock Purchase Agreements

As of December 31, 2014

The Company entered into restricted stock purchase agreements with certain founders and employees for the issuance of
restricted common stock in exchange for services. Under the terms of the restricted stock purchase agreements, the Company has the right to repurchase any unvested shares at the original issue price (ranging from $0.18 per share to $4.76 per share)
in the event of termination of service. These repurchase rights lapse over the vesting term, which varies by agreement.

The restricted stock was purchased in exchange for promissory notes (Notes) that, prior to repayment in October
2014, accrued interest at rates ranging from 0.89% to 2.89% annually, with interest payable annually. The principal, along with any unpaid accrued interest, was payable upon the earlier of certain corporate transactions including an initial public
offering, the termination of services, or nine to ten years from the date of the promissory notes. The Company had recourse against the restricted stock issued along with the Notes and recourse of up to 80% of the principal amount, and up to the
full amount of accrued interest, against the individuals personal assets.

The Company has accounted for the Notes
as non-recourse in their entirety since the Notes are not aligned with a corresponding percentage of the underlying shares. Accordingly, the non-recourse notes received by the Company as consideration for the issuance of the restricted stock have
been considered as stock options for accounting purposes as the substance is similar to the grant of an option since the employee generally will relinquish the stock in lieu of repaying the Note. Nonrefundable principal payments are recorded as a
credit to additional paid-in capital for the underlying shares that are vested as of the repayment date and as a repurchase liability for the underlying shares that are unvested as of the repayment date. Nonrefundable interest is recorded as
interest income.

The number of shares of restricted stock outstanding subject to the Companys right of repurchase
at prices ranging from $0.18 to $1.28 per share for the year ended December 31, 2014 was 1,434,466. The liability for shares subject to repurchase as of December 31, 2014 was $0.9 million, of which $0.6 million is included in accrued
liabilities and $0.3 million is included in other long-term liabilities.

These restricted stock arrangements are accounted for similarly to stock
options until the Notes are repaid. During the year ended December 31, 2014, 528,745 restricted shares were repurchased from ten stockholders. During the eight months ended December 31, 2013, 1,031,415 restricted shares were
repurchased from one stockholder. During the year ended April 30, 2013, a total of 536,458 restricted shares were repurchased from two stockholders. Because the restricted shares are accounted for as options, the Notes are not recorded in the
accompanying consolidated balance sheets, the shares are excluded in the totals for common stock outstanding as December 31, 2013 and April 30 2013, and compensation cost is recognized over the requisite service period with an offsetting
credit to additional paid-in capital. In October 2014, in anticipation of the Companys IPO, all outstanding promissory notes were repaid in full and the restricted stock that had vested became shares of common stock. The fair value of the
options were determined based on the Black-Scholes option pricing model using the following assumptions:

Periodic principal payments were recorded as a credit to additional paid-in capital for the
underlying shares that were vested as of the repayment date and as a repurchase liability for the underlying shares that are unvested as of the repayment date. The shares are recorded when they vest and when principal payments are received. The

Early Exercise of Stock Options

The 2011 Plan allowed for the granting of options that may be exercised before the options have vested. Shares issued as a
result of early exercise and shares that had not vested are deemed to be restricted stock and are subject to a vesting schedule identical to the vesting schedule of the related restricted stock and options, as well as certain other restrictions.
Shares issued as a result of early exercise that have not vested are subject to repurchase by the Company upon termination of the purchasers employment or services, at the price paid by the purchaser, and are not deemed to be issued for
accounting purposes until those related shares vest. The amounts received in exchange for these shares have been recorded as a liability on the accompanying balance sheets and will be reclassified into common stock and additional paid-in-capital as
the shares vest. The Companys right to repurchase these shares generally lapses 1/48 of the original grant date per month over four years.

The number of shares of restricted stock outstanding subject to the Companys right of repurchase at prices ranging from
$0.18 to $14.22 per share for the year ended December 31 2014 was 170,262. The liability for shares subject to repurchase as of December 31, 2014 was $1.1 million, of which $0.4 million is included in accrued liabilities and $0.7 million
is included in other long-term liabilities.

2014 Employee Stock Purchase Plan

In September 2014, the Companys board of directors adopted and approved, and in November 2014 the Companys
stockholders adopted and approved, the Employee Stock Purchase Plan, or the ESPP. The ESPP initially reserves and authorizes the issuance of up to a total of 2,500,000 shares of common stock to participating employees. The ESPP provides that
the number of shares reserved and available for issuance will automatically increase each January 1, beginning on January 1, 2015, by the lesser of (i) 1,000,000 shares of common stock, (ii) 1% of the outstanding number of shares
of the Companys common stock on the immediately preceding December 31, or (iii) such lesser number of shares as determined by the ESPP administrator. This number is subject to adjustment in the event of a stock split, stock dividend
or other change in the Companys capitalization.

Each employee who is a participant in the ESPP may purchase shares
by authorizing payroll deductions of up to 10% of his or her base compensation during an offering period. Unless the participating employee has previously withdrawn from the offering, his or her accumulated payroll deductions will be used to
purchase shares on the last business day of the offering period at a price equal to 85% of the fair market value of the shares on the first business day or the last business day of the offering period, whichever is lower. Under applicable tax rules,
an employee may purchase no more than $25,000 worth of shares of common stock, valued at the start of the purchase period, under the ESPP in any calendar year. No offering period was available in fiscal year 2014.

Determining Fair value for Non-employees

Stock-based compensation expense related to stock options and RSUs granted to non-employees is recognized as the stock options
and RSUs are vested. As of December 31, 2014, the Company granted options to purchase 345,834 shares of common stock to non-employees and 28,125 RSUs with a weighted-average exercise price of $4.28 per share and 127,969 of these shares were
outstanding with a weighted-average exercise price of $4.78 per share.

The Company granted non-employees options to
purchase and restricted stock units to convert to a total of 230,625 shares of common stock for the year ended December 31, 2014, 11,750 and 50,000 for the eight months ended December 31, 2013 and 2012 (unaudited), respectively, and 50,000
and 135,834 for the years ended

April 30, 2013 and 2012, respectively. Compensation expense related to these options was $1.2 million for the year ended December 31, 2014, $106,000 and $35,000 for the eight months
ended December 31, 2013 and 2012 (unaudited), respectively, and $55,000 and $2,000 during the years ended April 30, 2013 and 2012, respectively.

The Company believes that the fair value of the stock options is more reliably measurable than the fair value of services
received. The fair value of the stock options granted is calculated at each reporting date using the Black-Scholes option pricing model with the following weighted-average assumptions:

As of December 31, 2014, unrecognized stock-based compensation of $44.9 million
related to unvested stock options, restricted stock, and restricted stock units, net of estimated forfeitures, is expected to be recognized on a straight-line basis over a weighted-average period of 3.59 years, respectively.

11. NET LOSS PER SHARE OF COMMON STOCK

Basic net loss per share is calculated by dividing net loss by the weighted-average number of common shares outstanding during
the period, less restricted common stock and common stock issued that is subject to repurchase, and excludes any dilutive effects of share based awards. Diluted net loss per share of common stock is computed giving effect to all potential dilutive
common shares, including common stock issuable upon exercise of stock options, and unvested restricted common stock. As the Company had net losses for the year ended December 31, 2014, the eight months ended December 31, 2013 and 2012
(unaudited), and the years ended April 30, 2013 and 2012, all potential common shares were determined to be anti-dilutive.

The Companys effective tax rate for the period ended December 31,
2014 was lower than the statutory tax rate primarily because of the valuation allowance on its US and foreign deferred tax assets and the losses of foreign subsidiaries taxed at lower rates, partially offset by state taxes and tax credits. The
losses of the foreign subsidiaries was generated primarily by our cost sharing agreement with our Netherlands operations.

The benefit for income taxes for the year ended December 31, 2014 relates primarily to the release of a valuation
allowance of $1.3 million associated with nondeductible intangible assets recorded as part of the XA Secure acquisition, partially offset by state minimum income tax and income tax on the Companys earnings in foreign jurisdictions. In
connection with the acquisition of XA Secure, a deferred tax liability was established for the book-tax basis differences related to the acquired developed technology. The net deferred tax liability from this acquisition creates an additional source
of income to offset the Companys deferred tax assets. As such, the impact on the acquiring Companys deferred tax assets and liabilities caused by an acquisition are recorded in the acquiring Companys consolidated financial
statements outside of acquisition accounting. The income tax expense for the year ended December 31, 2014, eight months ended December 31, 2013 and 2012, and the years ended April 30, 2013 and 2012 relates to state minimum income tax
and income tax on the Companys earnings in foreign jurisdictions.

A valuation allowance is provided when it is more
likely than not that the deferred tax assets will not be realized. The Company has established a valuation allowance to offset net deferred tax assets at December 31, 2014 due to the uncertainty of realizing future tax benefits from its net
operating loss carryforwards and other deferred tax assets. The net valuation allowance increased by approximately $54.8 million during the year ended December 31, 2014. As of December 31, 2014, the Company had net operating loss (NOL)
carryforwards for federal and state tax purposes of approximately $124.0 million and $142.5 million, respectively. The NOL carryforwards will expire at various dates beginning in 2031 (federal) and 2023 (state), unless previously utilized. The
Company also has federal and state research and development tax credit carryforwards of approximately $2.0 million and $2.0 million, respectively. The federal tax credits will expire at various dates beginning in 2031, unless previously utilized.
The state tax credits do not expire and will carry forward indefinitely until utilized.

As a result of certain
realization requirements of the accounting guidance for stock-based compensation, the table of deferred tax assets and liabilities shown above does not include certain deferred tax assets at December 31, 2014 and 2013 that arose directly from
(or the use of which was postponed by) tax deductions related to equity compensation in excess of compensation recognized for financial reporting. Approximately $4.0 million of federal net operating losses and $3.3 million of state net operating
losses relate to stock compensation deductions in excess of book expense, the tax effect of which would be to credit additional-paid-in-capital if realized.

Current laws impose substantial restrictions on the utilization of net operating loss and credit carryforwards in the event of
an ownership change within a three year period as defined by the Internal Revenue Code Section 382. If there should be an ownership change, the Companys ability to utilize its carryforwards could be limited.

The Company has not recorded a provision for deferred U.S. tax expense that could result from the remittance of foreign
undistributed earnings since the Company intends to reinvest the earnings of these foreign subsidiaries indefinitely. The amount of unrecognized deferred tax liability related to these earnings is insignificant.

The Company recorded unrecognized tax benefits for uncertain tax positions of
approximately $1.0 million as of December 31, 2014, $0.6 million as of December 31, 2013 and $0.4 million as of April 30, 2013, of which none would impact the effective tax rate, if recognized, because the benefit would be offset by
an increase in the valuation allowance.

The Companys policy is to recognize interest and penalties accrued on any
unrecognized tax benefits as a component of income tax expense. During the year ended December 31, 2014, the Company recognized no interest and penalties associated with unrecognized tax benefits. There are no tax positions for which it is
reasonably possible that the total amounts of unrecognized tax benefits will significantly increase or decrease within 12 months of the reporting date.

The Company files income tax returns in the U.S. federal jurisdiction, various state jurisdictions and foreign jurisdictions.
The Companys tax years for fiscal year end 2011 and forward are subject to examination by the U.S. tax authorities and various state tax authorities, and the Companys tax years for fiscal year end 2013 and forward are subject to
examination by various foreign tax authorities.

14. 401(K) PLAN

The Company has a qualified defined contribution plan under Section 401(k) of the Internal Revenue Code covering eligible

15. RELATED PARTY TRANSACTIONS

In June 2011, the Company entered into a two-year commercial agreement with Yahoo! Inc. (Yahoo! is listed as Customer B in
Note 2), a principal shareholder, that requires the Company to provide support subscription, and the Company issued a preferred stock warrant to Yahoo! (the 2011 Yahoo! Warrant). The initial total contract value was $2.0 million and
is being paid in quarterly installments of $250,000. In June 2013, the commercial agreement was amended to automatically renew for an additional year on an annual basis, unless otherwise terminated by either party 60 days prior to the end of the
then-current renewal period. Refer to Note 8 for further discussion of the 2011 Yahoo! Warrant.

In February 2012, the
Company entered into a development, distribution and marketing agreement with Teradata Corporation, a significant shareholder. Under this and subsequent arrangements, the Company is providing support subscription and professional services to
Teradata and certain of its end users. In April 2012, the Company received a nonrefundable prepayment of $9.5 million from Teradata as consideration for the support subscription offerings and professional services expected to be performed by
the Company over the three-year term of this agreement. For this related party arrangement, the Company did not record contra revenue for the associated equity.

In September 2013, the Company entered into a common stock purchase agreement with an affiliate of AT&T covering the sale
and issuance of 390,269 shares of the Companys stock for a nominal amount of consideration (AT&T is listed as Customer D in Note 2). The initial grant included restricted shares that were subject to repurchase rights by the
Company. 50% of the shares vest on an equal and ratable basis over an 18-month period beginning on October 1, 2013 and the remaining 50% of shares vest in their entirety on March 31, 2015. Concurrently, the Company also entered into a
commercial agreement with AT&T to provide specified support subscription and professional services over a 3-year term with a minimum annual fee of $6.0 million. Due to the lack of VSOE, this fee is being recognized ratably over the three year
term. The fair value of approximately $382,000 related to the common shares where the repurchase right expired as of December 31, 2013 was recognized as contra-revenue. In January 2014, the Company entered into an amended stock purchase
agreement with an affiliate of AT&T in which the Company relinquished its repurchase rights, at which point the fair value of the remaining shares was recognized as a reduction in revenue. The contra-revenue amount of $2.0 million was determined
based on the fair value of the common stock on the date of modification of the stock purchase agreement.

In June 2014,
the Company issued a warrant to purchase a number of shares of common stock in exchange for the amendment of certain rights held by Yahoo! Under the Investors Rights Agreement to approve certain corporate transactions involving
Hortonworks. The warrant became exercisable upon the consummation of the IPO at which point the fair value of the award was reclassified to equity. As of December 31, 2014, the warrant is exercisable for 476,368 shares of the Companys
common stock. The combined value of the initial measurement and the change in the fair value of this warrant of $5.4 million was recorded as other expense in the consolidated statement of operations for the year ended December 31, 2014.

In July 2014, the Company entered into a Series D preferred stock purchase
agreement with Hewlett-Packard Company covering the sale and issuance of 2,051,349 shares of the Companys stock for a total of $50.0 million. Under this and subsequent arrangements, Hewlett-Packard resells the Companys support
subscription services. The Company receives a net percentage of the gross dollars collected from Hewlett-Packards end-user customers related to such support and professional services. For this related party arrangement, the Company did not
record contra revenue for the associated equity as the Series D preferred stock was issued at fair value.

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

Our management, with the participation of our Chief Executive Officer and our Chief Financial Officer, has evaluated the effectiveness of our
disclosure controls and procedures as of the end of the period covered by this Annual Report on Form 10-K. The term disclosure controls and procedures, as defined in Rules 13a-15(e) and 15d-15(e) under the Exchange Act, means controls
and other procedures of a company that are designed to ensure that information required to be disclosed by a company in the reports that it files or submits under the Exchange Act is recorded, processed, summarized and reported, within the time
periods specified in the SECs rules and forms at the reasonable assurance level. Disclosure controls and procedures include, without limitation, controls and procedures designed to ensure that information required to be disclosed by a company
in the reports that it files or submits under the Exchange Act is accumulated and communicated to the companys management, including its principal executive and principal financial officers, or persons performing similar functions, as
appropriate to allow timely decisions regarding required disclosure. Management recognizes that any controls and procedures, no matter how well designed and operated, can provide only reasonable assurance of achieving their objectives and management
necessarily applies its judgment in evaluating the cost-benefit relationship of possible controls and procedures. Based on such evaluation, our Chief Executive Officer and Chief Financial Officer have concluded that, as of such date, our disclosure
controls and procedures were effective at the reasonable assurance level.

Changes in Internal Control over Financial Reporting

There was no change 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 quarter ended December 31, 2014 that has materially affected, or is reasonably likely to materially affect, our internal control over financial reporting.

Managements Report on Internal Control over Financial Reporting

The Annual Report on Form 10-K does not include a report of managements assessment regarding internal control over financial reporting or
an attestation report of our independent registered public accounting firm due to a transition period established by the rules of the SEC for newly public companies.

Inherent Limitations of Internal Controls

Our management, including our principal executive officer and principal financial officer, does not expect that our disclosure controls and
procedures or our internal controls will prevent all error and all fraud. A control system, no matter how well conceived and operated, can provide only reasonable, not absolute, assurance that the objectives of the control system are met. Because of
the inherent limitations in all control systems, no evaluation of controls can provide absolute assurance that all control issues and instances of fraud, if any, within the Company have been detected. These inherent limitations include the realities
that judgments in decision making can be faulty, and that breakdowns can occur because of a simple error or mistake. Additionally, controls can be circumvented by the individual acts of some persons, by collusion of two or more people, or by
management override of the control. The design of any system of controls also is based in part upon certain assumptions about the likelihood of future events, and there can be no assurance that any design will succeed in achieving its stated goals
under all potential future conditions. Over time, controls may become inadequate because of changes in conditions, or the degree of compliance with the policies or procedures may deteriorate. Because of the inherent limitations in a cost-effective
control system, misstatements due to error or fraud may occur and not be detected.

Item 9B. Other Information.

None.
