QuinStreet Grows 32%; Financial Services Strong, Education Accelerates

Company Reports $104M Revenue, $25M Adjusted EBITDA

Foster City, CA — November 3, 2010 — QuinStreet, Inc. (NASDAQ: QNST), a leader in vertical marketing and media online, today announced its financial results for the fiscal first quarter ended September 30, 2010.

For the quarter, the Company reported total revenue of $103.6 million, an increase of 32% over revenue reported in the same quarter last year.

The Company reported net income of $7.5 million, or $0.16 per diluted share, for the quarter. Adjusted net income for the quarter was $13.5 million, or $0.29 per diluted share. Adjusted net income excludes stock-based compensation expense and amortization of intangible assets, net of estimated tax.

Revenue for the Financial Services client vertical was $49.8 million, an increase of 61% as compared to the same quarter of last year. Revenue for the Education client vertical was $42.6 million, an increase of 5% as compared to the year-ago quarter. Revenue for the Education client vertical grew 20% excluding changes in revenue from a large education client undergoing a previously disclosed change in its online marketing strategy. Revenue for Other client verticals was $11.2 million, an increase of 57% as compared to the year-ago quarter.

Adjusted EBITDA for the quarter was $24.6 million, or 24% of revenue.

Reconciliations of adjusted net income to net income, adjusted EBITDA to net income, and free cash flow to net cash provided by operating activities are included in the accompanying tables.

“We are pleased to report our fourth consecutive quarter of year-over-year revenue growth of 30% or more. We are also excited to have exceeded quarterly revenue of $100 million for the first time,” commented Doug Valenti, QuinStreet CEO. “Revenue grew significantly in each of our client verticals, and we have never seen stronger client demand, visitor traffic or competitive advantages. Our business momentum is strong. Our markets are enormous, and despite our success to date, we are still very early in our penetration and growth potential.”

“We remain maniacally focused on execution and on delivering shareholder value, as we have since we started the Company 11 years ago. This is our ninth consecutive year of strong growth and strong, consistent profitability,” concluded Valenti.

Non-GAAP Financial Measures

This release and the accompanying tables include a discussion of adjusted EBITDA, adjusted net income, adjusted diluted net income per share and free cash flow, all of which are non-GAAP financial measures that are provided as a complement to results provided in accordance with accounting principles generally accepted in the United States of America (“GAAP”). The term “adjusted EBITDA” refers to a financial measure that we define as net income less provision for taxes, depreciation expense, amortization expense, stock-based compensation expense, interest and other income (expense), net. The term “adjusted net income” refers to a financial measure that we define as net income adjusted for amortization expense and stock-based compensation expense, net of estimated taxes. The term “adjusted diluted net income per share” refers to a financial measure that we define as adjusted net income divided by weighted average diluted shares outstanding. The term “free cash flow” refers to a financial measure that we define as net cash provided by operating activities, less capital expenditures and internal software development costs. These non-GAAP measures should be considered in addition to results prepared in accordance with GAAP, but should not be considered a substitute for, or superior to, GAAP results. In addition, our definition of adjusted EBITDA, adjusted net income, adjusted diluted net income per share and free cash flow may not be comparable to the definitions as reported by other companies.

We believe adjusted EBITDA, adjusted net income, adjusted diluted net income per share and free cash flow are relevant and useful information because they provide us and investors with additional measurements to analyze the Company’s operating performance.

Adjusted EBITDA is part of our internal management reporting and planning process and one of the primary measures used by our management to evaluate the operating performance of our business, as well as potential acquisitions. Adjusted EBITDA is useful to us and investors because it provides information related to the Company’s ability to provide cash flow for acquisitions, capital expenditures and working capital requirements. Internally, adjusted EBITDA is used by management for planning purposes, including preparation of internal budgets; to allocate resources to enhance financial performance; to evaluate the effectiveness of operational strategies; and to evaluate the Company’s capacity to fund acquisitions and capital expenditures as well as the capacity to service debt. Adjusted EBITDA is used as a key financial metric in senior management’s annual incentive compensation program. The Company believes that analysts and investors use adjusted EBITDA as a supplemental measurement to evaluate the overall operating performance of companies in its industry and use adjusted EBITDA multiples as a metric for analyzing company valuations. It is also an element of certain maintenance covenants under our debt agreements.

Adjusted net income and adjusted diluted net income per share are useful to us and investors because they present an additional measurement of our financial performance, taking into account depreciation, which we believe is an ongoing cost of doing business, but excluding the impact of certain non-cash expenses (stock-based compensation and amortization of intangible assets). The Company believes that analysts and investors use adjusted net income and adjusted diluted net income per share as supplemental measures to evaluate the overall operating performance of companies in our industry.

Free cash flow is useful to us and investors because it represents the cash that our business generates from operations, before taking into account cash movements that are non-operational, and is a metric commonly used in our industry to understand the underlying cash generating capacity of a company’s financial model. The Company believes that analysts and investors use free cash flow multiples as a metric for analyzing company valuations in our industry. Free cash flow has certain limitations in that it does not represent the total increase or decrease in the cash balance for the period, nor does it represent the residual cash flow for discretionary expenditures. Therefore, we think it is important to evaluate free cash flow along with our consolidated statement of cash flows.

We intend to provide these non-GAAP financial measures as part of our future earnings discussions and, therefore, the inclusion of these non-GAAP financial measures will provide consistency in our financial reporting. A reconciliation of these non-GAAP measures to GAAP is provided in the accompanying tables.
