2/24/2018 S-1 Table of Contents • increase our technical support costs; and • harm our reputation and brand. We may acquire other businesses or receive offers to be acquired, which could require significant management attention, disrupt our business, or dilute stockholder value. Part of our business strategy is to make acquisitions of other companies, products, and technologies. We have limited experience in acquisitions. We may not be able to find suitable acquisition candidates and we may not be able to complete acquisitions on favorable terms, if at all. If we do complete acquisitions, we may not ultimately strengthen our competitive position or achieve our goals, and any acquisitions we complete could be viewed negatively by users, developers, or investors. In addition, we may not be able to integrate acquired businesses successfully or effectively manage the combined company following an acquisition. If we fail to successfully integrate our acquisitions, or the people or technologies associated with those acquisitions, into our company, the results of operations of the combined company could be adversely affected. Any integration process will require significant time and resources, require significant attention from management, and disrupt the ordinary functioning of our business, and we may not be able to manage the process successfully, which could adversely affect our business, results of operations, and financial condition. In addition, we may not successfully evaluate or utilize the acquired technology and accurately forecast the financial impact of an acquisition transaction, including accounting charges. We may have to pay cash, incur debt, or issue equity securities to pay for any such acquisition, each of which could affect our financial condition or the value of our capital stock. The sale of equity to finance any such acquisitions could result in dilution to our stockholders. If we incur more debt, it would result in increased fixed obligations and could also subject us to covenants or other restrictions that would impede our ability to flexibly operate our business. Our business may be significantly impacted by a change in the economy, including any resulting effect on consumer or business spending. Our business may be affected by changes in the economy generally, including any resulting effect on spending by our business and consumer users. Some of our users may view a subscription to our platform as a discretionary purchase, and our paying users may reduce their discretionary spending on our platform during an economic downturn. If an economic downturn were to occur, we may experience such a reduction in the future, especially in the event of a prolonged recessionary period. As a result, our business, results of operations, and financial condition may be significantly affected by changes in the economy generally. Our business could be disrupted by catastrophic events. Occurrence of any catastrophic event, including earthquake, fire, flood, tsunami, or other weather event, power loss, telecommunications failure, software or hardware malfunctions, cyber­attack, war, or terrorist attack, could result in lengthy interruptions in our service. In particular, our U.S. headquarters and some of the datacenters we utilize are located in the San Francisco Bay Area, a region known for seismic activity, and our insurance coverage may not compensate us for losses that may occur in the event of an earthquake or other significant natural disaster. In addition, acts of terrorism could cause disruptions to the internet or the economy as a whole. Even with our disaster recovery arrangements, our service could be interrupted. If our systems were to fail or be negatively impacted as a result of a natural disaster or other event, our ability to deliver products to our users would be impaired or we could lose critical data. If we are unable to develop adequate plans to ensure that our business functions continue to operate during and after a disaster, and successfully execute on those plans in the event of a disaster or emergency, our business, results of operations, financial condition, and reputation would be harmed. 31 https://www.sec.gov/Archives/edgar/data/1467623/000119312518055809/d451946ds1.htm 38/235
