SINA (NASDAQ:SINA) announced solid fourth-quarter 2018 results on Tuesday morning, once again highlighting the benefits of the Chinese internet technology company's burgeoning Weibo microblogging platform.

But while SINA also followed with strong guidance for the coming year, management urged caution based on regulatory pressures in China that could hamper some of its most promising opportunities. 

With shares down around 3% in Tuesday afternoon trading as of this writing, let's dig in to better understand what SINA had to say.

  • Adjusted revenue rose 14% to $570.4 million.

  • Advertising revenue rose 14% to $484.3 million, driven by a 25% increase to $417 million in Weibo advertising and marketing sales. SINA portal advertising revenue declined 29.3% year over year to just under $67.4 million. 
  • Adjusted non-advertising revenue grew 13% year over year to $86.1 million, driven primarily by Weibo's recently acquired live broadcasting business. SINA portal non-ad revenue declined 21% with continued weakness in the payments business.

What management had to say

During the subsequent conference call, CFO Bonnie Yi Zhang stated that Weibo's monthly active users climbed by 70 million from the year-ago period to 462 million, growing faster than the overall Chinese internet population last year. 

"Weibo has become a designated place for public and social interactions, events, discovery and discussion, as well as interest exploration," she added. "These unique attributes have helped the platform to attract and accumulate increased amounts of organic traffic."

Zhang noted the portal ad business was hurt by advertising budget cuts at small and medium enterprise customers in industries under tightened government regulation, including fintech and online gaming.

Looking forward

"Heading into 2019, we are seeing the resumption of game license approval and a series of government's seamless policies...which may serve as catalysts for revenue growth," Zhang said. "However, we continue to face challenges in tightened regulation of contents scrutiny and the online finance, as well as macro uncertainties eroding advertisers' sentiment."

As such, for the full fiscal-year 2019, SINA expects revenue to climb to between 16.5 billion yuan to 17.5 billion yuan, or roughly $2.44 billion to $2.59 billion. That would be good for growth of 18% to 25%, assuming currency exchange rates remain steady.

Most analysts were already modeling 2019 revenue near the low end of that range. But shares are already up more than 20% year to date leading into this report. And so, when you combine SINA's outsized reliance on Weibo with the ongoing concerns over the macroeconomic environment and Chinese regulatory headwinds, it's no surprise to see the stock pulling back today.
