A Burlington-based medical-testing company that employs about 1,000 people in the Triangle could be an acquisition target.

Shares of LabCorp jumped today on speculation that the company may be bought, Jefferies Group analyst Arthur Henderson told Bloomberg News.

LabCorp reported in a regulatory filing this morning that it altered its change-of-control provisions to eliminate additional severance pay to senior executives for excise taxes from payments related to a takeover.

That filing fueled speculation about a leveraged buyout, Henderson told Bloomberg. “These rumors have been building up for a couple of weeks,” Henderson said.

LabCorp shares rose $2.35 today to close at $79.33. The stock is up 27 percent in the past year.

Shares of larger rival Quest Diagnostics also jumped on buyout speculation, rising $1.60 to $59.86.

LabCorp, which employs about 28,000 people worldwide, announced last month that it will add 346 jobs in Greensboro as it consolidates billing operations from across the country. The company's operations include a massive genetics-testing facility in Research Triangle Park.

CancerGuide Diagnostics was founded in 2006 and is run by CEO Myla Lai-Goldman, the former chief medical officer at Burlington-based medical testing giant LabCorp.

LabCorp contributed to CancerGuide's financing, along with local venture capital firms Hatteras Venture Partners and Intersouth Partners.

LabCorp also agreed to work with CancerGuide on developing and commercializing new cancer tests that will help doctors determine early on what treatments will have the best results for particular patients.

"There is a tremendous need for diagnostic tools to optimize the management of the disease and take full advantage of available therapeutic options,” Lai-Goldman said in a prepared statement.

On Thursday, Guilford County commissioners approved giving the company $248,791. Greensboro also is offering $373,000. And the state would contribute a $275,000 grant, Dan Lynch, president of the Greensboro Economic Development Alliance told the Greensboro News-Record.

The jobs would pay about $27,000 a year. LabCorp employs about 28,000 workers worldwide, including more than 1,000 in the Triangle.

For example, Monogram’s tests help identify patients who are likely to respond to a certain type of HIV drugs.

“By utilizing LabCorp’s national infrastructure to build on Monogram’s already strong sales, we will advance our leadership in infectious disease and cancer testing, companion diagnostics and personalized medicine,” said David P. King, CEO of LabCorp.

The company employs about 1,000 in the Triangle and 25,000 worldwide. It has expanded to become the largest employer in Burlington, about an hour west of Raleigh.
