Properties, in its own words

During our first fiscal quarter of 2027, we will transition to our new corporate headquarters located in Santa Clara, California, consisting of approximately 301,000 square feet of space under a sublease agreement that expires on April 30, 2032. Under a sublease that expires on October 31, 2026, we also lease approximately 172,000 square feet of space in San Jose, California, which currently serves as our corporate headquarters. We also maintain offices elsewhere in the United States, as well as multiple locations internationally, including in Asia, Europe and the Middle East. We lease all of our facilities and do not own any real property. We expect to add facilities as we grow our employee base and expand geographically.

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 our operations.

Risk factors and legal proceedings

The risks Zscaler names in Item 1A of its 10-K filed Sep 3, 2026: 56 risks under these headings, as written.19

  • Risks Related to Our Business
  • We have a history of annual net losses and may not be able to achieve or sustain profitability in the future.
  • If organizations do not adopt our cloud platform, our ability to grow our business and operating results may be adversely affected.
  • If we are unable to attract new customers, our future results of operations could be harmed.
  • If our customers do not renew their subscriptions for our services and add additional users and services to their subscriptions, our future results of operations could be harmed.
  • We have experienced rapid revenue and other growth in recent periods, which may not be indicative of our future performance.
  • If we fail to effectively manage our growth, we may be unable to execute our business plan, maintain high levels of service, adequately address competitive challenges or maintain our corporate culture, and our business, financial condition and results of operations would be harmed.
  • Our operating results may fluctuate significantly, which could make our future results difficult to predict and could cause our operating results to fall below expectations.
  • Our business and growth depend in part on the success of our relationships with our channel partners.
  • We face intense and increasing competition and could lose market share to our competitors, which could adversely affect our business, financial condition and results of operations.
  • If the delivery of our services to our customers is interrupted or delayed for any reason, our business would suffer.
  • If we fail to develop or introduce new enhancements to our cloud platform, including AI enhancements, on a timely basis, our ability to attract and retain customers, remain competitive and grow our business could be impaired.
The other 45 risks
  • If our global network of data centers, which deliver our services, was damaged or otherwise failed to meet the requirements of our business, our ability to provide services to our customers and maintain the performance of our cloud platform could be negatively impacted, which could cause our business to suffer.
  • If our cloud platform or internal networks, systems or data are or are perceived to have been breached, our solution may be perceived as insecure, our reputation may be damaged and our financial results may be negatively impacted.
  • If our cloud platform does not interoperate with our customers’ network and security infrastructure or with third-party products, websites or services, our cloud platform may become less competitive and our results of operations may be harmed.
  • If we are not able to maintain and enhance our brand, our business and results of operations may be adversely affected.
  • If we do not effectively develop and expand our sales and marketing capabilities, we may be unable to add new customers or increase sales to our existing customers, and our business will be adversely affected.
  • Our sales cycles can be long and unpredictable, and our sales efforts require considerable time and expense.
  • Because we recognize revenue from subscriptions for our services over the term of the subscription, downturns or upturns in new business may not be immediately reflected in our operating results and may be difficult to discern.
  • We provide service level commitments under our customer contracts. If we fail to meet these contractual commitments, we could be obligated to provide credits for future service and our business could suffer.
  • Our ability to maintain customer satisfaction depends in part on the quality of our customer support, including the quality of the support provided on our behalf by certain channel partners. Failure to maintain high-quality customer support could have an adverse effect on our business, financial condition and results of operations.
  • We rely on our key technical, sales and management personnel to grow our business, and the loss of one or more key employees or the inability to attract and retain qualified personnel could harm our business.
  • Our business depends, in part, on sales to the public sector and significant changes in the contracting or fiscal policies of public sector organizations could have an adverse effect on our business and operating results.
  • Our international operations expose us to significant risks, and failure to manage those risks could materially and adversely impact our business.
  • Future acquisitions, strategic investments, partnerships or alliances could be difficult to identify and integrate, divert the attention of key management personnel, disrupt our business, dilute stockholder value and adversely affect our operating results, financial condition and prospects.
  • If we are unable to effectively manage certain risks and challenges related to our India operations, our business could be harmed.
  • Our failure to raise additional capital necessary to expand our operations and invest in new solutions could reduce our ability to compete and could harm our business.
  • The actual or perceived failure of our cloud platform to block malware or prevent a security breach or incident could harm our reputation and adversely impact our business, financial condition and results of operations.
  • Issues in the development, use and execution of AI and ML, combined with an uncertain regulatory environment and evolving market expectations, may harm our business.
  • We incorporate technology from third parties into our cloud platform, and our inability to obtain or maintain rights to the technology could harm our business.
  • Some of our technology incorporates "open source" software, and we license some of our software through open source projects, which could negatively affect our ability to sell our platform and subject us to possible litigation.
  • We rely on a limited number of suppliers for certain components of our cloud platform and the systems we use to operate our business and provide services to our customers, and any disruption in the availability of these components could delay our ability to expand or increase the capacity of our global data center network, replace defective equipment in our existing data centers or otherwise operate our business and provide services to our customers.
  • Claims by others that we infringe their proprietary technology or other rights, or other lawsuits asserted against us, could result in significant costs and substantially harm our business, financial condition, results of operations and prospects.
  • The success of our business depends in part on our ability to protect and enforce our intellectual property rights.
  • Adverse economic conditions or reduced IT security spending may adversely impact our revenue and profitability.
  • Failure to comply with laws and regulations applicable to our business could subject us to fines and penalties.
  • If we were not able to satisfy data protection, security, privacy and other government- and industry-specific requirements or regulations, our business, results of operations and financial condition could be harmed.
  • We are subject to governmental import and export controls and trade and economic sanctions and other trade controls including tariffs that could impair our ability to compete in international markets and subject us to liability if we are not in full compliance with applicable laws.
  • We are exposed to fluctuations in currency exchange rates, which could negatively affect our operating results.
  • We are subject to counterparty default risks.
  • Our corporate structure and intercompany arrangements are subject to the tax laws of various jurisdictions, and we could be obligated to pay additional taxes, which would harm our results of operations.
  • Our ability to use our net operating loss carryforwards and certain other tax attributes may be limited.
  • Taxing authorities may successfully assert that we should have collected or in the future should collect sales and use, value added or similar taxes, and we could be subject to liability with respect to past or future sales, which could adversely affect our operating results.
  • Risks Related to the Ownership of Our Common Stock
  • The concentration of our stock ownership with insiders will likely limit your ability to influence corporate matters, including the ability to influence the outcome of director elections and other matters requiring stockholder approval.
  • Certain 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 members of our board of directors or current management and may adversely affect the market price of our common stock.
  • The market price of our common stock may be volatile, and you could lose all or part of your investment.
  • Sales of substantial amounts of our common stock in the public markets, or the perception that they might occur, as well as any issuances of our common stock in connection with the conversion of the 2028 Notes or other securities convertible or exercisable into shares of our common stock, could reduce the price that our common stock might otherwise attain and may dilute your voting power and your ownership interest in us.
  • We do not intend to pay dividends in the foreseeable future. As a result, your ability to achieve a return on your investment will depend on appreciation in the price of our common stock.
  • If industry or financial analysts issue inaccurate or unfavorable research regarding our common stock, our stock price and trading volume could decline.
  • Our amended and restated certificate of incorporation provides that the Court of Chancery of the State of Delaware and the federal district courts of the United States are the exclusive forums for substantially all disputes between us and our stockholders, which could limit our stockholders’ ability to obtain a favorable judicial forum for disputes with us or our directors, officers or employees.
  • Risks Related to the 2028 Notes
  • Servicing of our debt will require a significant amount of cash, which may impact our cash available for working capital, capital expenditures and other corporate purposes.
  • The capped call transactions may affect the value of our common stock.
  • We are subject to counterparty risk with respect to the capped call transactions.
  • General Risks
  • We are subject to anti-corruption, anti-bribery and similar laws, and noncompliance with such laws can subject us to criminal penalties or significant fines and harm our business and reputation.
  • If we fail to maintain an effective system of internal controls, our ability to produce timely and accurate financial statements or comply with applicable regulations could be impaired.
  • If our estimates or judgments relating to our critical accounting policies prove to be incorrect or financial reporting standards or interpretations change, our results of operations could be adversely affected.
  • We may become involved in litigation that may materially and adversely affect us.
