“We are pleased to have delivered our third consecutive quarter with year-over-year revenue growth of 30% or more. Revenue grew significantly in all verticals, but for one client,” commented Doug Valenti, QuinStreet CEO. “Financial Services continues to grow rapidly and is now our largest vertical. Education client demand is at record levels as we are benefiting from a ‘flight to quality’ driven by regulatory scrutiny and change, and as clients anticipate and adapt to new higher standards.

“We continued to spend aggressively on the development of new capabilities and future growth opportunities in the quarter, while delivering EBITDA margins above target levels. Fiscal 2010 was our eighth straight year of strong growth and strong, consistent profitability. We look forward to many more. QuinStreet has never had stronger client demand, visitor traffic or competitive advantages. We are more excited than ever about the size and attractiveness of our markets.

“We remain confident in our long-term guidance of 15-20% annual growth and 20% EBITDA margins, and we expect to meet or exceed those rates of growth and profitability in the coming year,” concluded Valenti.
