BOSTON ( TheStreet) -- The following fast-growth companies are projected to increase revenue and profit by at least 12% in the coming year and receive "buy" ratings from our proprietary quantitative model, which considers more than 60 factors. They are ordered by their potential to appreciate.

Teva Pharmaceuticals ( TEVA) is an Israeli company that develops and markets a range of generic and branded pharmaceuticals, biogenerics and active pharmaceutical ingredients.

The operating margin declined to 18% and the net margin increased to 14%. The company has conservative leverage, as reflected by a debt-to-equity ratio of 0.5.

The numbers: First-quarter revenue increased 28% to $125 million as net income jumped 24% to $29 million and earnings per share improved 26% to $2.07.

NCI ( NCIT) provides IT engineering and professional services to federal agencies. With mounting budget deficits and a growing national debt, Washington is looking to streamline. NCI offers an attractive play on this trend.

The numbers: First-quarter revenue increased 15% to $105 million as net income rose 29% to $4.7 million and earnings per share climbed 26% to 34 cents.
