NEW YORK (TheStreet) -- Tetra Tech (TTEK) - Get Report has been upgraded by TheStreet Ratings from Hold to Buy with a ratings score of B.  TheStreet Ratings Team has this to say about their recommendation:

TheStreet Ratings team rates TETRA TECH INC as a Buy with a ratings score of B. TheStreet Ratings Team has this to say about their recommendation:

"We rate TETRA TECH INC (TTEK) a BUY. This is driven by a few notable strengths, which we believe should have a greater impact than any weaknesses, and should give investors a better performance opportunity than most stocks we cover. The company's strengths can be seen in multiple areas, such as its largely solid financial position with reasonable debt levels by most measures, reasonable valuation levels and notable return on equity. We feel these strengths outweigh the fact that the company has had sub par growth in net income."

Highlights from the analysis by TheStreet Ratings Team goes as follows:

• TTEK's debt-to-equity ratio is very low at 0.20 and is currently below that of the industry average, implying that there has been very successful management of debt levels. To add to this, TTEK has a quick ratio of 1.81, which demonstrates the ability of the company to cover short-term liquidity needs.
• TETRA TECH INC' earnings per share from the most recent quarter came in slightly below the year earlier quarter. This company has reported somewhat volatile earnings recently. We feel it is likely to report a decline in earnings in the coming year. During the past fiscal year, TETRA TECH INC turned its bottom line around by earning $1.66 versus -$0.03 in the prior year. For the next year, the market is expecting a contraction of 0.9% in earnings ($1.65 versus $1.66).
• TTEK, with its decline in revenue, underperformed when compared the industry average of 3.0%. Since the same quarter one year prior, revenues fell by 10.0%. The declining revenue appears to have seeped down to the company's bottom line, decreasing earnings per share.
• The company's current return on equity greatly increased when compared to its ROE from the same quarter one year prior. This is a signal of significant strength within the corporation. When compared to other companies in the Commercial Services & Supplies industry and the overall market, TETRA TECH INC's return on equity is below that of both the industry average and the S&P 500.
