The U.K.’s increasingly messy attempt to withdraw through the European Union, called Brexit, is actually creating uncertainty for U.S. tech companies, who are starting to warn investors about possible fallout.

Salesforce disclosed in its annual filing last week in which the item is actually moving away through a “U.K.-centralized European structure” in addition to investing in some other European cities like Dublin to mitigate the impact of Brexit on its business. Salesforce books most of its European revenue in British Pounds as its U.K. subsidiary plays a central role within the region, yet the item will at This specific point allow its some other European offices to recognize revenues in local currencies to reduce exchange rate volatility, the item said.

“Brexit could adversely affect U.K., regional (including European) in addition to worldwide economic in addition to market conditions in addition to could contribute to instability in global financial in addition to foreign exchange markets, including volatility within the value of the British Pound in addition to Euro,” Salesforce wrote within the filing.

Salesforce is actually part of a growing number of tech companies addressing the potential impact of Brexit, a move in which could add significant uncertainty to businesses in Europe. Although British lawmakers are Once more anticipated to vote to delay Brexit, which is actually scheduled for later This specific month, more investors are asking about its future risk.

within the past three months, 93 earnings calls of the S&P 500 companies addressed Brexit in addition to its potential impact, according to FactSet. Among those are some of the largest companies, including Facebook, Cisco in addition to Walmart.

While most companies were cautious with their answers, sharing very little detail, some companies were more upfront about the item.

Expedia, for example, said the item’s seen a drop-off in U.K flight bookings due to “uncertainty around Brexit.” Booking Holdings, the owner of a group of travel sites including Priceline.com, also said Brexit is actually creating a “tremendous amount of uncertainty.”

Facebook’s CFO David Wehner also said during January’s earnings call in which macroeconomic concerns, like Brexit, are a “risk on top of some other issues” facing the company.

some other companies tried to play down Brexit’s effect on its business. HPE CEO Antonio Neri said demand was “very steady” throughout the quarter, highlighting double-digit sales growth within the U.K. Walmart’s CEO Doug McMillon said he’s “impressed” with his U.K. team’s performance, while Cisco CEO Chuck Robbins said he’s been “amazed at the resilience” he’s seen through employees around the entire world.

the item’s unclear why Salesforce decided to share more details about Brexit’s potential impact. The company generates less 20 percent of revenue through the European region, a smaller share than companies like Facebook or Cisco, who get about a quarter of their sales through Europe. Salesforce’s representative wasn’t immediately available for comment.

Still, Salesforce said the item’s already “evaluated in addition to commenced to implement initiatives,” as the item sees “significant uncertainties” arising through Brexit’s outcome.

“We recognize in which there are still significant uncertainties surrounding the ultimate resolution of Brexit negotiations, in addition to we will continue to monitor any improvements in which may arise in addition to assess their potential impact on our business,” Salesforce said within the filing.
