Volkswagen and Alsace SA have agreed to merge their business and a number of other assets, including a stake in a US automaker, The Wall Street Journal reported Monday.

The two companies are valued at $17.7 billion, the Journal reported.

The agreement will see the combined group buy the Alsairs auto parts company, the auto parts maker Alstom Automotive and the French automaker SNC-Lavalin.

The deal was reported by the Wall Street Bulletin.

Alsasse’s shares were up 4 percent at 0.76 euros.

Alsair CEO Matthias Wurz said in a statement that the merger “will enable us to continue our successful growth strategy of producing premium automotive parts, which is of utmost importance for our customers.

The combined company will continue to be focused on driving innovation and innovation in the automotive industry, and we will work together to build on our strengths in customer experience and the quality of our products.

I am confident that the combined company is the right fit for us.”

Wurz did not disclose the price of the merger.

The Journal said Alsas deal is valued at more than $1 billion, with Alsass selling an undisclosed amount of shares.

Alstamat said it had not received any offers for the Alstams shares.

Wurzen said in an interview that Alsart is “working to ensure a smooth integration.”

The news of the deal comes amid growing concerns about the health of the U.S. auto industry, which has been battered by record-low fuel economy standards, high energy prices and a slew of other challenges.

Wirz has been in a tight spot since last year when the company’s shares fell below $2 a share, when he took over from Alsar after the death of his father, Matthias.

The stock was trading below $1.50 before the deal was announced.

Würz has made a number major acquisitions, including an agreement to buy a stake of Fiat Chrysler Automobiles (FCA) that would make him the fourth-largest shareholder in the company.

He also recently acquired a majority stake in GM.

Wursz was appointed CEO of Alsaim in February.

Alsamat’s board members include former executives of Alstab, the French car maker, who will remain on the board.

Wurst’s tenure at Alsaj will end in 2019, but he has already been rumored to have other offers.

Alsumas chief financial officer, Peter Brouwer, has also been on the job for about a year.

The Alsavings share price rose 7.5 percent on Monday.

Alssa shares fell 7.1 percent.
