SAN FRANCISCO — Facebook cautioned Wall Street on Wednesday that it could face intensifying difficulties in its advertising business from the coronavirus pandemic, but also indicated that the toll would not be deep.

The company, which reported rising revenue and profit for the first three months of the year, said that it experienced a significant reduction in advertising in the last three weeks of March and that its business would continue to be affected by “issues beyond our control.” It added that it would not give forecasts about future financial results because of the coronavirus impact.

But the ad declines flattened in April, Facebook said, adding that it had “seen signs of stability” and that “advertising revenue has been approximately flat compared to the same period a year ago.”

Coupled with relatively robust financial results from Google’s parent company, Alphabet, on Tuesday and from Microsoft on Wednesday, Facebook and other tech giants appear to be limiting the pain from the pandemic as people flock to their digital services while in lockdown.
