FOSTER CITY, CA – August 6, 2026 – QuinStreet, Inc. (Nasdaq: QNST), a leader in performance marketplaces and technologies for the financial services and home services industries, today announced financial results for the fiscal fourth quarter and fiscal year ended June 30, 2026.

For the fiscal fourth quarter, the Company reported revenue of $373.9 million, up 43% year-over-year.

GAAP net income for the fiscal fourth quarter was $19.1 million, or $0.33 per diluted share. Adjusted net income for the fiscal fourth quarter was $29.0 million, or $0.50 per diluted share.

Adjusted EBITDA for the fiscal fourth quarter was $41.4 million, up 87% year-over-year.

For full fiscal year 2026, the Company reported revenue of $1.3 billion, up 18% year-over-year.

GAAP net income for fiscal year 2026 was $81.2 million, or $1.40 per diluted share. Adjusted net income for fiscal year 2026 was $73.8 million, or $1.27 per diluted share.

Adjusted EBITDA for fiscal year 2026 was $112.5 million, up 38% year-over-year.

For full fiscal year 2026, the Company generated $130.9 million in operating cash flow and closed the quarter with $128.3 million in cash and cash equivalents.

“Fiscal Q4 was another record quarter of strong performance and progress, capping a record year for QuinStreet,” commented Doug Valenti, CEO of QuinStreet. “We grew quarterly revenue 43% year-over-year with strength in both Financial Services and Home Services. Adjusted EBITDA was up 87% year-over-year and came in at an 11.1% margin, a 270 basis-point improvement over the year-ago quarter.”

“For full fiscal year 2026, revenue grew 18% year-over-year to $1.3 billion, and adjusted EBITDA grew 38% year-over-year to $112.5 million, an 8.7% margin and a 130-basis point year-over-year margin expansion. Over the past 2 years, we have more than doubled our revenue and grown adjusted EBITDA by more than 450%.”

“We expect to continue to grow revenue at strong double-digit rates and to expand margins in fiscal year 2027 and beyond. Our market opportunities are large, and we believe that we are still in their early innings. Our revenue growth continues to be driven by the relentless shift of marketing budgets to digital and performance marketing, and by our proven ability to consistently deliver results at scale for clients. Our key competitive advantage continues to be our industry-leading technologies, including our core AI optimization algorithms. We are also accelerating improvements in performance and productivity from new AI applications across the business.”

“Turning to our outlook, we expect revenue in fiscal Q1 to be between $370 and $380 million, implying 31% growth year-over-year at the midpoint of the range. We expect adjusted EBITDA to be between $38 and $40 million, implying 90% growth, a 10.4% margin and a 320 basis-point margin expansion year-over-year at the midpoint of the range.”

“As an initial full fiscal year 2027 outlook, we expect revenue of $1.45 billion to $1.55 billion, implying 16% growth year-over-year at the midpoint of the range. We expect adjusted EBITDA of $150 to $160 million, implying growth of 38%, a 10.3% margin and another 160 basis-point margin expansion year-over-year at the midpoint of the range on top of last year’s 130 basis-point expansion. We believe that there may be opportunities to grow revenue and expand margins even further, and we will refine our outlook as the year progresses,” concluded Valenti.

Non-GAAP Financial Measures and Definitions of Client Verticals

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 and normalized 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 (loss) excluding depreciation and amortization expense, stock-based compensation expense, interest and other expense, net, provision for (benefit from) income taxes, restructuring costs, acquisition costs, litigation settlement expense, impairment charges, and contingent consideration adjustment. The term "adjusted net income" refers to a financial measure that we define as net income (loss) adjusted for amortization expense, stock-based compensation expense, acquisition costs, contingent consideration adjustment, litigation settlement expense, restructuring costs, impairment charges, tax valuation allowance, and the related income tax effects of these adjustments. The term "adjusted diluted net income (loss) 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. The term “normalized free cash flow” refers to free cash flow less changes in operating assets and liabilities. 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 and normalized free cash flow may not be comparable to the definitions as reported by other companies.

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

Adjusted EBITDA is useful to us and investors because (i) we seek to manage our business to a level of adjusted EBITDA as a percentage of net revenue, (ii) it is used internally by us for planning purposes, including preparation of internal budgets; to allocate resources; to evaluate the effectiveness of operational strategies and capital expenditures as well as the capacity to service debt, (iii) it is a key basis upon which we assess our operating performance, (iv) it is one of the primary metrics investors use in evaluating Internet marketing companies, (v) it is a factor in determining compensation, (vi) it is an element of certain financial covenants under our historical borrowing arrangements, and (vii) it is a factor that assists investors in the analysis of ongoing operating trends. In addition, we believe adjusted EBITDA and similar measures are widely used by investors, securities analysts, ratings agencies and other interested parties in our industry as a measure of financial performance, debt-service capabilities and as a metric for analyzing company valuations.

We use adjusted EBITDA as a key performance measure because we believe it facilitates operating performance comparisons from period to period by excluding potential differences caused by variations in capital structures (affecting interest expense), tax positions (such as the impact of changes in effective tax rates or fluctuations in permanent differences or discrete quarterly items), non-recurring charges, certain other items that we do not believe are indicative of core operating activities (such as litigation settlement expense, acquisition costs, contingent consideration adjustment, restructuring costs, impairment charges and other income and expense) and the non-cash impact of depreciation expense, amortization expense and stock-based compensation expense.

With respect to our adjusted EBITDA guidance, the Company is not able to provide a quantitative reconciliation to the most directly comparable GAAP financial measure without unreasonable efforts due to the high variability, complexity and low visibility with respect to certain items such as taxes, and income and expense from changes in fair value of contingent consideration from acquisitions. We expect the variability of these items to have a potentially unpredictable and potentially significant impact on future GAAP financial results, and, as such, we also believe that any reconciliations provided would imply a degree of precision that would be confusing or misleading to investors.

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, amortization of intangible assets, and contingent consideration adjustment), non-recurring charges and certain other items that we do not believe are indicative of core operating activities. We believe 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 investors and us 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. Normalized free cash flow is useful as it removes the fluctuations in operating assets and liabilities that occur in any given quarter due to the timing of payments and cash receipts and therefore helps investors understand the underlying cash flow of the business as a quarterly metric and the cash flow generation potential of the business model. We believe that analysts and investors use free cash flow multiples as a metric for analyzing company valuations in our industry.

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.
