"Our advertising revenues are affected by numerous external factors, including economic conditions, market dynamics, audience fragmentation and evolving digital advertising trends.
We derive substantial revenues from the sale of advertising in our products. Advertising spending is sensitive to overall economic conditions, and our advertising revenues could be adversely affected if advertisers respond to weak and uneven economic conditions by reducing their budgets or shifting spending patterns or priorities, or if they are forced to consolidate or cease operations. Among other things, an economic slowdown or other negative impact on worldwide economic conditions from the outbreak and spread of the coronavirus (COVID-19) could materially adversely impact our advertising revenues.
In determining whether to buy advertising, our advertisers consider the demand for our products, demographics of our reader base, advertising rates, results observed by advertisers, breadth of advertising offerings and alternative advertising options."

"Our operations are vulnerable to the effects of epidemics, such as the coronavirus, which could materially disrupt our business.
We are vulnerable to the general economic effects of epidemics and other public health crises, including the ongoing coronavirus outbreak that has surfaced in China and is spreading throughout the world. Due to the recent outbreak of the coronavirus, there has been a substantial curtailment of business activities, particularly to and from China, which may potentially affect our ability to conduct fieldwork. The risk is particularly pronounced where our teams need to visit traditional stores to collect information where electronic data transmission is not possible, and where we need to conduct face to face consumer research interviews. Further, the virus could have a negative impact on our business if clients decide to cut back their research spend in China or other countries in light of poor performance due to the virus, and if it is not contained or otherwise continues, the impact of the epidemic could have a material adverse effect on our business."

For the first quarter of 2020, Weibo’s business has been significantly impacted by the coronavirus outbreak in China. Due to the high uncertainty of the evolving situation, we have limited visibility on the full quarter revenue impact brought upon by the epidemic. Based on our current best estimate, Weibo anticipates its first quarter of 2020 net revenues to decrease by 15% to 20% year-over-year on a constant currency basis. This forecast reflects Weibo’s current and preliminary view, which is subject to change."
