Health care products distributor Henry Schein Inc. moved up to No. 287 on the annual Fortune 500 listing released Thursday, joining Cablevision Systems Corp. as Long Island's sole representatives on the list of the largest U.S. companies that disclose their annual financial results. The companies are ranked by annual revenue.

Melville-based Henry Schein, which has been on the Fortune list for 11 years, moved up five slots from the previous year.

"Henry Schein's 11-year climb up the Fortune 500 rankings is a testament to the shared commitment and values of our more than 18,000 Team Schein members across the globe," Stanley M. Bergman, chairman and chief executive, said in a statement.

Telecommunications provider Cablevision, which owns Newsday, came in at No. 419 after placing 397th last year. It has been on the list 17 years.

Topping the Fortune 500 was retailing giant Walmart Stores, followed by Exxon Mobil, Chevron, and Warren Buffett's conglomerate Berkshire Hathaway. No. 5 Apple was followed by General Motors, Phillips 66, General Electric, Ford Motor Co. and CVS Health.

Henry Schein had net sales in 2014 of $10.4 billion, up from $4.1 billion in 2004 when it debuted on the list at No. 487, the company said. Cablevision had net sales in 2014 of $6.5 billion.

Long Island has seen its roster of public companies shrink as companies were acquired or moved out of the region.

In 2000, the Fortune 500 list included former Long Island companies Arrow Electronics, Computer Associates, The Olsten Corp. and Avis Rent a Car.

Arrow moved its headquarters to Colorado in 2011. CA Technologies, as Computer Associates is now known, moved its headquarters to Manhattan last year. In 2000, Olsten was gobbled up by Swiss staffing rival Adecco and Avis was acquired by Cendant Corp. In 2006, Cendant changed its name to Avis Budget Group, Inc., now based in Parsippany, N.J.
