Twitter Inc. (NYSE: TWTR) is slated to report its fourth-quarter 2019 earnings results on Thursday before the market opens. The bottom line will be hurt by higher costs and expenses related to revenue product issues and seasonality while the strength in US advertising continues to drive the top-line growth.

The top-line growth rate is likely to be lesser than previous quarters due to the negative impact of its mobile application promotion advertisements and the issues in personalization and data settings. The ad engagements are likely to increase year-over-year as audience and clickthrough rates across most ad formats could drive ad impressions for the quarter.

Most of the advertising revenue is generated by selling its promoted products. This consists of promoted tweets, which appear within a timeframe, search results or profile pages just like an ordinary tweet regardless of device, promoted accounts, and promoted trends.

The company is expected to continue investing in revenue products as it works to improve ads platform and ad formats to deliver increased value to advertisers around the world. Advertising revenue continued to be driven by sales momentum with advertisers, built around differentiated ad formats, better relevance, and improved return on investment.

Analysts expect the company’s earnings to decline by 6.50% to $0.29 per share while revenue will jump by 9.70% to $996.73 million for the fourth quarter. The company has surprised investors by beating analysts’ expectations thrice in the past four quarters. The majority of the analysts recommended a “hold” rating with an average price target of $34.08.

For the full year 2019, capital expenditures are anticipated to be at or near the low end of the prior forecast range of $550-600 million.
