finds itself in a delicate position with the onslaught of the deadly virus: As COVID-19 forces more people indoors and wreaks havoc on the economy, it is driving record use on the social network while at the same time robbing it of advertising revenue in the short term.

“In a time of disaster, people rely more on social services more… we are seeing surges in traffic, especially in areas most affected,” Zuckerberg said in a conference call with reporters last week. “People want to stay connected while being asked to maintain social distancing and eliminate loneliness.”

Daily calls on WhatsApp and Messenger have doubled, reaching levels normally seen only on New Year’s Eve, he added. (Facebook does not monetize Messenger and WhatsApp at the same rate as its core and Instagram businesses.)

Then there is the flip side. A large chunk of advertisers who brought in $70.7 billion in sales for Facebook last year are small businesses most at risk during the expected COVID-19 economic slowdown.

will suffer losses because of their reliance on small businesses that advertise,” eMarketer senior analyst Jasmine Enberg told MarketWatch. “[Small businesses] will pull back ad spend. In the longer term (full year), they are in a much better position than smaller media companies for advertising.”

said it now expects an operating loss in its current first quarter, and a dip in revenue because of COVID-19. Twitter had expected operating income to be between break even and $30 million, and total revenue of $825 million to $885 million for the quarter.

According to the Johns Hopkins Coronavirus website, countries most afflicted by COVID-19 are China, the largest countries in Europe, the U.S., Iran, and South Korea. The U.S. (including Canada) and Europe accounted for 51% of Facebook’s advertising revenue last quarter, FBN Securities analyst Shebly Seyrafi said in a note Wednesday, “so clearly the majority of FB’s advertising revenue is being pressured currently,” he wrote.

Facebook reported $21.08 billion in fourth-quarter revenue, nearly all of it from advertising.

“FB’s concession… cause us to lower our FQ1 revenue growth forecast for FB from $18.60B (up 23% Y/Y) to $17.5B (up 16% Y/Y),” Seyrafi wrote. While he maintains an Outperform rating on Facebook, he lowered his price target to $220 from $245.

Seyrafi further reduced his earnings per share estimate to $1.79 from $2.04. He models Facebook revenue to grow 16% to 17% in fiscal 2020 before accelerating to 19% in 2021.

Analysts polled by FactSet, meanwhile, have lowered their estimates on Facebook’s sales and earnings.

Estimates for advertising, which accounts for nearly all of Facebook’s sales, have declined from $18.37 billion to $18.13 billion in that time period, according to FactSet.

Earnings expectations from FactSet were $1.95 per share at the end of 2019. As of March 25, they were $1.91 per share.

Shares of Facebook were down 3% in early afternoon trading. For the year, they are down 24%.
