Almost 60 transactions totalling $34.5 billion have been struck by foreign companies for British firms since June 23, according to Thomson Reuters data, compared with 79 deals amounting to $4.3 billion in the month leading up to the vote.

This activity—dominated by Japanese group SoftBank’s $32 billion swoop for chip designer ARM Holdings—has defied warnings that dealmaking could dry up for a period if Britain backed Brexit, given uncertainty surrounding risks to the economy and access to the EU single market.

The list of British takeovers could grow after the summer, according to bankers who say they are working on possible bids on behalf of foreign companies interested in UK targets.

The SoftBank deal was hailed by the government as a sign of UK economic resilience, prompting new Prime Minister Theresa May to declare the country “open for business.”

But M&A bankers said some of the post-vote takeovers had more to do with the relatively low valuations of British companies given current exchange rates, rather than being driven by confidence in the British economy.

Sterling has taken the brunt of market concern since the Brexit vote on June 23, falling to a 31-year low in the aftermath of the vote.

“Clearly this is a buying opportunity,” said Ben Ward, head of UK corporate at law firm Herbert Smith Freehills. “People with strong currencies—dollar, renminbi, yen—will no doubt be interested in acquiring sound sterling-denominated assets.”

There have been dozens of other deals since the referendum.

South African retailer Steinhoff agreed to pay nearly 600 million pounds for British-based discount chain Poundland on July 13, for example.

It came a day after AMC Entertainment Holdings —an American company majority-owned by a Chinese conglomerate—said it would buy London-based Odeon & UCI Cinemas Group to create the world’s largest cinema operator, in a deal valued at about 921 million pounds.

On Thursday, China’s Fosun International snapped up English football club Wolverhampton Wanderers.

Some M&A bankers in London say they are working closely with British companies who feel vulnerable to hostile bids from cash-rich foreign buyers, in sectors including aerospace, housebuilding and retail. Others say they are trying to win advisory mandates at firms viewed as potential takeover targets.

“We’re helping our UK clients think through the right fundamental value of their business in the current environment and shoring them up to prevent unwanted opportunistic situations where an international rival tries to buy them on the cheap,” said Hernan Cristerna, co-head of global M&A at JPMorgan.

U.S. and Asian conglomerates are also stepping up efforts to secure bargain deals unseen in decades, sources said.

Some have hired banks to resurrect deals that were aborted in recent years because of price disagreements.

After the vote British companies have become 10-15% cheaper for overseas buyers due to the devaluation of the pound which was trading at $1.31 on July 22 against $1.50 the day before the referendum.

“When you have a material currency discontinuity it makes sense to dust off previous M&A analyzes and crunch the numbers again,” said Paulo Pereira, a partner at boutique advisory firm Perella Weinberg.

Surveys conducted in the run-up to the referendum had warned a Brexit vote would threaten M&A activity.

A study released on June 16 by Merrill Corporation, a provider of technology and services in the M&A industry, and market intelligence firm The M&A Advisor found a Brexit vote would have a “negative and tangible” near-term impact on UK dealmaking, with British companies becoming less attractive to overseas buyers.

A survey of 1,500 global dealmakers published the same day by technology provider Intralinks suggested a decision to leave the EU would lead to dealmaking “chaos,” driving down M&A levels in Britain as well as the rest of Europe.

But the M&A drought has yet to materialize.

The sectors with the highest concentration of foreign takeovers in the past four weeks were technology, consumer, industrials and media, with an overall 37 sales valued at $33 billion. Industry sources said some had roots in discussions that began well ahead of the June referendum.

“If we have learned one thing from the global financial crisis it’s that standing still means moving backwards,” said Steve Krouskos, EY Global Vice Chair, Transaction Advisory Services, adding that companies need to carry on doing deals to boost their organic growth, build a global presence and stay ahead of the technology curve.

JPMorgan’s Cristerna stressed that “boards still have strategic needs and ambitions and need to remain open to external sources of growth.”

Pricing aside, however, dealmaking will still be tough for overseas buyers who must evaluate the uncertainty surrounding Britain’s future relationship with the EU, and the prospects of a messy divorce that may take several years to conclude.

Additionally, any sizable takeover could face tighter government scrutiny, after May pledged to oppose foreign companies trying to buy British champions deemed “strategically important,” citing the sale of chocolatier Cadbury (CBY) in 2010 and Pfizer’s (PFE) attempted takeover of AstraZeneca (AZN) in 2014.

But SoftBank’s friendly takeover of ARM, which won the blessing of the government in less than 24 hours, established a useful blueprint for dealmaking following the Brexit vote, banking sources said.

The Japanese company made legally-binding commitments to double ARM’s UK headcount in the next five years and preserve its Cambridge headquarters.

“There is so much ‘political football’ going on that if you want to pull off a significant transaction in a sensitive sector it is wise to start planning some concessions beforehand to ease government approval,” said Perella’s Pereira.
