** Italy's Atlantia SpA ATL.MI and Spain's Acs Actividades de Construccion y Servicios SA ACS.MC will finalize their purchase of Abertis in the coming weeks, three sources close to the matter said, dismissing concerns the deal could fall apart after a bridge operated by an Atlantia business collapsed.

Buyout firm Thoma Bravo LLC has agreed to buy Imperva Inc IMPV.O for $2.1 billion in cash, adding the cybersecurity firm to its technology-heavy investment portfolio, the company said. Aircraft parts supplier TransDigm Group Inc TDG.N has agreed to buy smaller rival Esterline Technologies Corp ESL.N for about $3.6 billion in its biggest-ever deal, as it seeks the heft to compete with Boeing (NYSE:BA) Co BA.N and Airbus SE AIR.PA in after-sales servicing. Britain's Revolution Bars Group RBG.L ended talks to buy nightclub operator Deltic Group, saying a deal would not be in the best interests of its shareholders.

U.S. oil firm Chevron (NYSE:CVX) CVX.N will become the first oil major to formally exit the Norwegian continental shelf, as it transfers its last stake in an exploration license, according to a government letter. South Korea's Lotte Corp 004990.KS said it planned to take a stake in Lotte Chemical 011170.KS for 2.2 trillion won ($1.93 billion) from two affiliates to improve its governance and efficiency. Leading shareholders in Sweden's Capio CAPIO.ST swung behind a $900 million takeover bid from France's Ramsay Generale de Sante GDSF.PA , paving the way for a deal to go through after the board backed it.

Japan's SoftBank Group Corp 9984.T is in talks to buy a majority stake in U.S. shared office space provider WeWork Cos, a source said, potentially doubling down on one of its biggest bets on a loss-making startup. Shares in Alps Electric Co 6770.T rose as much as 2.8 percent after a regulatory filing a day earlier showed U.S. hedge fund Elliott Management Corp had boosted its stake in the company to 9.22 percent from 6.26 percent. Australian education provider Navitas Ltd NVT.AX said on Tuesday it had received a A$1.97 billion ($1.4 billion) takeover bid from an Australian private equity firm and the company's co-founder, sending its shares 20 percent higher.
