(Reuters) -Twitter Inc shares sank 11% in post-market trading on Thursday as it offered tepid revenue guidance for the second quarter, warned of rising costs and expenses and said user growth could slow as the boost seen during the coronavirus pandemic fizzles.
The social media company posted revenues and user numbers mostly in line with analyst estimates in stark contrast to the better performing digital ad firms like Facebook Inc and Alphabet Inc's.
It said it expected second quarter revenue between $980 million and $1.08 billion, lower than Wall Street estimates of $1.06 billion on average, according to IBES data from Refinitiv. It also said stock based compensation for new hires would be more than expected this year.
Twitter says it wants to reset after years of product stagnation, announcing in February bold goals to expand its user base, speed up new features for users, and double its revenue by 2023.
"The explosive growth that Twitter experienced during the pandemic is slowing rather rapidly in the aftermath of an eventful 2020 in which the microblogging site benefited immensely from the U.S. elections and a pandemic-driven surge," said Haris Anwar, senior analyst at Investing.com.
Ad revenue for the first quarter were $899 million, up 32% from the same period a year ago and beating analyst estimates of $890 million. Total revenue for the quarter was $1.04 billion, up 28% year-over-year and slightly higher than estimates of $1.03 billion.
Google and Facebook, the top two largest digital advertising platforms, both blew past revenue expectations in their first quarters. Advertisers consider both to have more ad formats and better ad targeting capabilities than Twitter.
Asked on a conference call with analysts why Twitter did not see the same growth surge as other digital ad firms, CFO Ned Segal said the company, which relies more on brand advertising, typically sees a slow start after the holidays, which was exacerbated by real-world events like the Jan. 6 Capitol riot.
Twitter reported 199 million daily active users, up 20% year-over-year, compared to analysts' estimates of 200 million, according to FactSet data.
The San Francisco-based company repeated its warning that growth of its monetizable daily active users (mDAU) - its term for daily users who can view ads - could reach "low double digits" in the next quarters, likely hitting a low point in Q2.
Segal said Twitter wanted to retain the users it added during the COVID-19 pandemic, so that "as economies open up, as the events that they've been watching from their sofas are now available in person...they continue to come to Twitter."
'TOO EARLY' TO TELL
Twitter pledged in February a goal to double its annual revenue to $7.5 billion in 2023 from $3.7 billion in 2020. Responding to criticism that was summed up by CEO Jack Dorsey this year as "we're slow, we're not innovative, and we're not trusted," the company has recently snapped up newsletter platform Revue and podcast company Breaker and teased a litany of new products.
The company is also testing a live audio feature "Spaces" to compete with Clubhouse. It is also working on ways for users to find topics of interest and has teased new ways for creators to make money on the site, from tipping to "super follows" where fans can pay for exclusive content.
Twitter, which banned former U.S. President Donald Trump following the Jan. 6 Capitol riot, remains in the spotlight over its content policies and algorithmic systems. Both Dorsey and Twitter's head of U.S. public policy appeared in front of Congress in recent weeks as lawmakers mull changes to social media platforms' liability protections.
Twitter said it expected total revenue to grow faster than expenses this year, assuming that the coronavirus is less of a factor and that it sees "modest impact" from Apple's changes.
But it said in its outlook that stock-based compensation expenses for this year will amount to $600 million, up from its previous guidance of between $525 million to $575 million, as the company ramps up hiring. It forecast capital expenditures to be $900 million and $950 million for the full year.
Twitter said it expects headcount, as well as total costs and expenses, to increase at least 25% in 2021 on a year-over-year basis.
