Carlos Slim succeeds in Spain after Soros snub

Heavily indebted Spanish construction company FCC has announced a refinancing deal with a company owned by Mexican billionaire Carlos Slim, just days after failing to reach a similar agreement with investor George Soros.

FCC is a Barcelona-based firm that is still gripped by the nation's housing slump after the global financial crash of 2008. The company has drawn a number of high-profile investors willing to take a punt on a recovery in the sector.

Last year, Microsoft co-founder Bill Gates bought shares in the company with Soros making a similar move back in January. FCC's shareholders then approved a 1 billion euro ($1.24 billion) capital increase last Thursday in the hope of further strengthening capital, reducing debt and improving financial results.

It wasn't long before the buyers came flooding in, with FCC in talks earlier this week with the Soros Fund Management LLC. However, an announcement on Monday confirmed that the discussions had finished without a deal, according to Reuters.

Instead, FCC then turned to Slim and his company, Inmobiliaria Carso, with the Mexican becoming the largest investors in the Spanish builder, according to Reuters, with a 25.634 percent stake. The investment is worth around 650 million euros, according to the reports.

Meanwhile, Spanish billionaire businesswoman and philanthropist Esther Koplowitz will reduce her stake, according to the newswire, and will hold a 22.433 percent chunk after originally having over 50 percent.

FCC were not immediately available for comment when contacted by CNBC.
