LONDON -- There is no Plan B.

That is what many companies across Europe have been telling investors since Britain voted to leave the European Union. The exit and its timing are so uncertain, executives say, that few companies had any meaningful contingency plans to either defend against the fallout or take advantage of the opportunity.

"I can't even assess the impacts this could have on us in operational terms," says Maurizio Focchi, chief executive of Focchi, a family-controlled Italian construction company with about 90% of its revenue in the U.K. Almost 70% of German firms surveyed by the Federation of German Industries, or BDI, ahead of the vote said they didn't know how they would react to a Brexit vote.

Vodafone Group PLC says the vote means it might have to move its headquarters from Newbury, England, to somewhere else in Europe. It also might not. It is "not yet possible to draw any firm conclusions," the company said last week.

"My message to my investors," says Michael O'Leary, chief executive of Ryanair Holdings PLC, Europe's biggest airline by passengers flown, "is don't ask me for what this means, because we don't know."

Any big election brings uncertainty for businesses. None in recent years has raised so many questions for corporations, over such a broad swath of industries and geography, as last month's vote by Britain to leave the EU. In the short term at least, that has paralyzed planning and investment in boardrooms across the continent.

Negotiations about how Britain will disentangle itself from the EU could last as long as two years and might not start until next year. The talks could maintain the status quo or radically alter Britain's relationship with the European common market.

Cie. de Saint-Gobain SA, a French maker of construction materials with large operations in the U.K., hadn't made plans for a possible Brexit because the timing and scope of any impact are impossible to pin down, said Chief Executive Pierre-André de Chalendar.

While many bigger firms opposed Brexit, many smaller British business owners said a break from Brussels would allow them to thrive unencumbered by EU regulations.

Emma Pullen, chief executive of British Hovercraft Co., a manufacturer of small hovercrafts near Sandwich, England, said there will be short-term uncertainties, but the vote was great news longer term. Her own contingency plan: She gave all 15 of her employees a paid holiday to celebrate.

In the immediate aftermath, no sector outside of finance has been convulsed more than airlines.

More than 70% of flights taking off or landing at British airports are international ones, with 53% of those on average bound for other EU countries, according to consultant Oliver Wyman. Ryanair and rivals with major hubs in Britain, including easyJet PLC and British Airways parent International Consolidated Airlines Group SA, are especially vulnerable.

Investors have punished the sector. On Monday, Ryanair shares in London were down 15.6% since the June 23 vote. EasyJet was off 29.5% and IAG was down 29%.

The falling pound threatens to boost costs of new planes and fuel, which are usually purchased in dollars. Most airlines hedge currency exposure, though that would only defer the pain if the pound's weakness is prolonged. The biggest long-term worry for the industry is how a split might affect years of harmonized rules and regulation governing civil aviation across Europe.

Mr. O'Leary, Ryanair's chief executive since 1994, called it the worst industry shock since the terror attacks of Sept. 11, 2001. Before going to bed the night of the vote, he authorized one of the steepest, recent fare sales at Ryanair.

Mr. O'Leary said the question of future traffic rights -- where and how frequently Ryanair can land at British airports -- is a big uncertainty. That makes planning for U.K. expansion impossible. Shortly after the vote he said he was unlikely to move any of the 50 new jets Ryanair is putting into service next year in the U.K.

As an Irish-based company, Ryanair may need to get a new air operator certificate, or AOC, from Britain, should the country leave the EU. The certificate is an internationally recognized permit granted to an airline that demonstrates it can fly safely. Airlines need a second license certifying they are financially healthy.

The British government last week postponed a politically charged decision on how to address a looming airport-capacity shortage in London. It cited the Brexit vote.

At rival easyJet, Chief Executive Carolyn McCall had a slightly more detailed Plan B. The budget carrier is based at a small airport in Luton, England, about an hour's drive from London. It is the hub of a sprawling European network. About 43% of its flights are outside the U.K.

Early Friday after the vote, Ms. McCall reached out to staff and made calls to investors. She had prewritten letters ready to ship off to European and British aviation regulators, urging them to quickly draft air regulations that a split would require.

Minutes after British Prime Minister David Cameron announced his plans to resign, Ms. McCall issued a statement aimed at easing investor concern.

British Airways' parent IAG took more drastic action. Ahead of the vote, Chief Executive Willie Walsh had avoided staking out a public position for the airline. Privately, he said, Brexit would be bad for business generally, but wouldn't materially affect IAG operations.

That changed June 24. Midmorning, IAG warned earnings growth would fall short of forecasts. Business travel, one of IAG's biggest profit drivers, had slowed significantly in the run-up to the referendum, the airline said. The vote's outcome made an expected recovery uncertain.

The following Monday, easyJet issued its own profit warning. For months, Ms. McCall had been talking informally to several other EU member countries about the airline's biggest problem in the event of a Brexit: It may need to set up an additional European headquarters somewhere besides Britain to allow it to hold on to its EU traffic rights.

In recent days, the company said, Ms. McCall's informal talks over a new European home have become formal ones.
