CORONA, CALIF. — Between new product lines, line extensions and brand relaunches, fiscal 2018 was one of innovation for the Monster Beverage Corp. — and the innovation paid, said Rodney C. Sacks, chairman and chief executive officer of Monster.

“We are pleased to report record net sales for both our 2018 fiscal fourth quarter and 2018 full year, driven by growth in our Monster Energy brand energy drinks and new energy drink introductions,” he said.

In 2018, Monster launched Caffe Monster and Espresso Monster ready-to-drink energy coffee drinks, and the company relaunched its Muscle Monster, Monster Maxx and White Dragon Tea lines. The company also added three new flavors to its Monster Hydro lineup and introduced Java Swiss Chocolate.

Net income at Monster in the 12 months ended Dec. 31 totaled $993,004,000, or $1.78 per share on the common stock, up 21% from $820,678,000, or $1.45 per share, in the same period a year ago. Net sales increased 13% to $3,807,183,000 from $3,369,045,000.

Net income at Monster in the fourth quarter ended Dec. 31, 2018, totaled $239,105,000, equal to 43c per share, up 25% from $201,321,000, or 36c, in the same period a year ago. Net sales increased 14% to $924,200,000 from $810,400,000.

Turning to 2019, innovation remains a priority for the company, Mr. Sacks said. Monster is in the process of launching Ultra Paradox, a line extension in its Ultra family, as well as Hydro Manic Melon and Hydro Mean Green in 25.4-oz PET bottles. In March, Monster plans to launch new Reign Total Body Fuel in six flavors and add Green Tea and Yerba Mate flavors to its Dragon Tea.

“Retail sales statistics for many countries around the world demonstrated that the energy category is continuing to grow and that Monster is generally growing ahead of the category in line with earlier periods,” Mr. Sacks said. “The new additions to the Monster family continue to add to the company’s sales. We are excited about the prospects for our brand and our new product launches.”
