Wedbush downgraded Tetra Tech (NASDAQ: TTEK) from Outperform to Neutral with a price target of $29.00 (from $32.00).

Analyst David L. Rose said, "Following the recent quarter’s results, we feel less comfortable with the consistency in the business, and believe the growth trajectory will likely be more uneven than we have anticipated. Consequently, we are downgrading to NEUTRAL as we see the upside/downside risk as about even."
