## Exhibit 99.1

**Exhibit 99.1**

**Independent Auditor's Report**

Board of Directors

Siren Group AG

Churerstrasse 47

8808 Pfäffikon SZ

***Opinion***

We have audited the consolidated financial statements of Siren Group AG and its subsidiary (the Company), which comprise the consolidated balance sheet as of December 31, 2024, and the related consolidated income statement, and statement of cash flow for the year then ended, and the related notes to the consolidated financial statements.

In our opinion, the accompanying consolidated financial statements present fairly, in all material respects, the financial position of the Company as of December 31, 2024, and the results of its operations and its cash flows for the year then ended in accordance with Swiss Law and the consolidation and valuation principles set out in the notes.

***Basis for Opinion***

We conducted our audits in accordance with auditing standards generally accepted in the United States of America (GAAS). Our responsibilities under those standards are further described in the Auditor's Responsibilities for the Audit of the Financial Statements section of our report. We are required to be independent of the Company and to meet our other ethical responsibilities, in accordance with the relevant ethical requirements relating to our audits. We believe that the audit evidence we have obtained is sufficient and appropriate to provide a basis for our unmodified audit opinion.

***Responsibilities of Management for the Financial Statements***

Management is responsible for the preparation and fair presentation of the consolidated financial statements in accordance with Swiss Law and the consolidation and valuation principles set out in the notes, and for the design, implementation, and maintenance of internal control relevant to the preparation and fair presentation of consolidated financial statements that are free from material misstatement, whether due to fraud or error.

In preparing the consolidated financial statements, management is required to evaluate whether there are conditions or events, considered in the aggregate, that raise substantial doubt about the Company's ability to continue as a going concern within one year after the date that the consolidated financial statements are available to be issued.

***Auditor's Responsibilities for the Audit of the Financial Statements***

Our objectives are to obtain reasonable assurance about whether the consolidated financial statements as a whole are free from material misstatement, whether due to fraud or error, and to issue an auditor's report that includes our opinion. Reasonable assurance is a high level of assurance but is not absolute assurance and therefore is not a guarantee that an audit conducted in accordance with GAAS will always detect a material misstatement when it exists. The risk of not detecting a material misstatement resulting from fraud is higher than for one resulting from error, as fraud may involve collusion, forgery, intentional omissions, misrepresentations, or the override of internal control. Misstatements are considered material if there is a substantial likelihood that, individually or in the aggregate, they would influence the judgment made by a reasonable user based on the consolidated financial statements.

In performing an audit in accordance with GAAS, we:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•Exercise professional judgment and maintain professional skepticism throughout the audit.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•Identify and assess the risks of material misstatement of the consolidated financial statements, whether due to fraud or error, and design and perform audit procedures responsive to those risks. Such procedures include examining, on a test basis, evidence regarding the amounts and disclosures in the consolidated financial statements.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•Obtain an understanding of internal control relevant to the audit in order to design audit procedures that are appropriate in the circumstances, but not for the purpose of expressing an opinion on the effectiveness of the Company's internal control. Accordingly, no such opinion is expressed.

------

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•Evaluate the appropriateness of accounting policies used and the reasonableness of significant accounting estimates made by management, as well as evaluate the overall presentation of the consolidated financial statements.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•Conclude whether, in our judgment, there are conditions or events, considered in the aggregate, that raise substantial doubt about the Company's ability to continue as a going concern for a reasonable period of time.

We are required to communicate with those charged with governance regarding, among other matters, the planned scope and timing of the audit, significant audit findings, and certain internal control-related matters that we identified during the audit.

**SIREN GROUP AG, 8808 Pfäffikon and its subsidiary**

**Notes**

**1. Principles**

1.1 General aspects

Siren Group AG was founded on the 23rd August 2016 (entry in the register of commerce). These consolidated financial statements were prepared according to the provision of the Swiss Law. The accompanying financial statements are presented on a consolidated basis including the accounts of Siren Group AG and its subsidiary, Siren Group USA, Inc. (together "the Company"). Where not prescribed by law, the significant accounting and valuation principles applied are described below. It should be noted that to ensure the company's going concern, the Company's financial statements may be influenced by the creation and release of hidden reserves. All material intercompany balances, transactions, income, and expenses have been eliminated in consolidation. The consolidated financial statements have been prepared in accordance with Swiss law.

1.2 Accounting and financial reporting in functional currency (USD)

The accounting and financial reporting are kept in US Dollar, which is defined as the business significant currency (functional currency).

1.3 Accounting policy disclosures

Going concern: the financial statements have been prepared on a going concern basis, as the Board of Directors has no intention or necessity to liquidate the Company or to curtail materially the scale of its operations.

Use of estimates: the preparation of financial statements in conformity with Swiss Law requires management to make estimates and assumptions that affect the reported amounts of assets, liabilities, income and expenses. Actual results may differ from these estimates.

Intangible assets: intangible assets are recognised at cost of development less accumulated amortisation and impairment losses. They are amortised on a straight-line basis over their estimated useful life of 5 years.

Trade accounts receivables: Trade accounts receivable are stated at nominal value less allowances for doubtful accounts. Allowances are established based on an assessment of the creditworthiness of customers and the ageing of receivables.

Revenue recognition: revenue is recognized in accordance with Swiss Law when it is probable that economic benefits will flow to the Company and the amount of revenue can be reliably measured. Revenue is recognised either when the lead is generated or for some customers, when the appointment is generated (i.e. when the Company call center books the appointment). A small number of contractors are on revenue share agreements - revenue is recognised as a % of the final sale price. This revenue is accrued monthly based on an estimate and trued up post month end using disposition reports received from the contractors at the start of the following month. Revenue associated with these agreements is minimal.

Treasury shares: Treasury shares are recognized as a deduction from equity at acquisition cost. Treasury shares do not carry voting rights and are not entitled to dividends. Should treasury shares be used for share-based payment programs, the difference between the fair value and any consideration paid by the recipient at the time of grant is recognised as personnel expenses.

Treasury participation certificates: Treasury participation certificates are accounted for analogously to treasury shares and are recognized as a reduction of equity at acquisition cost. Treasury participation certificates held by the Company do not carry dividend or voting rights. Should treasury participation certificates be used for share-based payment programs, the difference between the fair value and any consideration paid by the recipient at the time of grant is recognised as personnel expenses.

Lease: leasing and rental contracts are recognized based on legal ownership. Therefore, any leasing or rental expenses are recognized as expenses in the period they are incurred; however, the leased or rented objects themselves are not recognized in the balance sheet.

Pension: the Company records its contribution to the pension plan in personnel expenses.

**SIREN GROUP AG, 8808 Pfäffikon and its subsidiary**

**(Unaudited)**

**Notes**

**1. Principles**

1.1 General aspects

Siren Group AG was founded on the 23rd August 2016 (entry in the register of commerce). These consolidated financial statements were prepared according to the provision of the Swiss Law. The accompanying interim financial statements are presented on a consolidated basis including the accounts of Siren Group AG and its subsidiary, Siren Group USA, Inc. (together "the Company"). Where not prescribed by law, the significant accounting and valuation principles applied are described below. It should be noted that to ensure the company's going concern, the Company's financial statements may be influenced by the creation and release of hidden reserves. All material intercompany balances, transactions, income, and expenses have been eliminated in consolidation. The consolidated financial statements have been prepared in accordance with Swiss law.

1.2 Accounting and financial reporting in functional currency (USD)

The accounting and financial reporting are kept in US Dollar, which is defined as the business significant currency (functional currency).

1.3 Accounting policy disclosures

Going concern: the financial statements have been prepared on a going concern basis, as the Board of Directors has no intention or necessity to liquidate the Company or to curtail materially the scale of its operations.

Use of estimates: the preparation of financial statements in conformity with Swiss Law requires management to make estimates and assumptions that affect the reported amounts of assets, liabilities, income and expenses. Actual results may differ from these estimates.

Intangible assets: intangible assets are recognised at cost of development less accumulated amortisation and impairment losses. They are amortised on a straight-line basis over their estimated useful life of 5 years.

Trade accounts receivables: Trade accounts receivable are stated at nominal value less allowances for doubtful accounts. Allowances are established based on an assessment of the creditworthiness of customers and the ageing of receivables.

Revenue recognition: revenue is recognized in accordance with Swiss Law when it is probable that economic benefits will flow to the Company and the amount of revenue can be reliably measured. Revenue is recognised either when the lead is generated or for some customers, when the appointment is generated (i.e. when the Company call center books the appointment). A small number of contractors are on revenue share agreements - revenue is recognised as a % of the final sale price. This revenue is accrued monthly based on an estimate and trued up post month end using disposition reports received from the contractors at the start of the following month. Revenue associated with these agreements is minimal.

Treasury shares: Treasury shares are recognized as a deduction from equity at acquisition cost. Treasury shares do not carry voting rights and are not entitled to dividends. Should treasury shares be used for share-based payment programs, the difference between the fair value and any consideration paid by the recipient at the time of grant is recognised as personnel expenses.

Treasury participation certificates: Treasury participation certificates are accounted for analogously to treasury shares and are recognized as a reduction of equity at acquisition cost. Treasury participation certificates held by the Company do not carry dividend or voting rights. Should treasury participation certificates be used for share-based payment programs, the difference between the fair value and any consideration paid by the recipient at the time of grant is recognised as personnel expenses.

Lease: leasing and rental contracts are recognized based on legal ownership. Therefore, any leasing or rental expenses are recognized as expenses in the period they are incurred; however, the leased or rented objects themselves are not recognized in the balance sheet.

Pension: the Company records its contribution to the pension plan in personnel expenses.

**EXPLANATORY NOTE**

These consolidated financial statements have been prepared in accordance with Swiss law and the consolidation and valuation principles set out in the notes.

The following is a narrative summary of material differences regarding the form, content and accounting principles that exist between the Swiss law regulations and accounting principles generally accepted in the United States of America (U.S. GAAP).

The income statement under Swiss law has been prepared using the type-of-expenditure format. Income and expense items are disclosed according to their type, irrespective of where they are incurred, and include the complete period expenses instead of cost of sales. Assets on the balance sheet are shown according to decreasing liquidity, i.e. highly liquid assets are shown on top of the balance sheet whereas fixed assets are shown on the bottom of the balance sheet. The same reporting principle applies to liabilities and equity.

Under Swiss law the Company is not obliged to present equity reconciliation statements. Also, the Company is only required to report limited disclosures in the notes to financial statements. Compared to requirements under U.S. GAAP, information in the Swiss law notes to financial statements are less detailed.

The following is a narrative summary of material accounting differences between Swiss law and U.S. GAAP:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•*Capitalization of internally developed software:* Under Swiss law, capitalization of internally developed software is generally broader, with development expenditures more frequently capitalized when the project's feasibility and future economic benefit are supportable. In contrast, U.S. GAAP applies more prescriptive criteria for internal use software, requiring expense of preliminary project and post-implementation activities and allowing capitalization only for qualifying application development stage costs once specific conditions are met. As a result, entities typically recognize higher capitalized software balances under Swiss law than under U.S. GAAP, with a corresponding reduction to period expense*.*

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•*Deferred Taxation:* Under Swiss law, there is no difference between tax and accounting basis. Therefore, Swiss law only requires current taxes to be recorded as there are no deferred taxes. Under U.S. GAAP, deferred tax liabilities and assets are based on the differences between the tax and accounting basis of assets and liabilities. Therefore, U.S. GAAP deferred tax accounting is more comprehensive than under Swiss law, with a valuation allowance recorded against deferred tax assets if they are not more-likely-than-not to be fully realized.

**Exhibit 99.2**

**UNAUDITED PRO FORMA CONDENSED COMBINED FINANCIAL INFORMATION** 

The following unaudited pro forma condensed combined financial information and notes thereto present the unaudited pro forma condensed combined balance sheet as of September 30, 2025 and the unaudited pro forma condensed combined statements of operations for the three months ended September 30, 2025 and the year ended June 30, 2025. The unaudited pro forma condensed combined financial information ("pro formas") of QuinStreet, Inc. ("QuinStreet" or the "Company"), has been prepared in accordance with Article 11 of Regulation S-X, as amended, and presents the combination of the historical financial information of QuinStreet and Siren Group AG ("HomeBuddy"), adjusted to give effect to the Acquisition (as defined below). The pro forma financial information of QuinStreet also gives effect to a financing event completed by QuinStreet that has occurred but is not yet reflected in the historical financial information of QuinStreet and is considered a material transaction separate from the Acquisition (as defined below).

**Description of the Acquisition**

On January 2, 2026 (the "Acquisition Date"), QuinStreet completed its acquisition (the "Acquisition") of HomeBuddy, pursuant to the terms of the share purchase agreement (the "Purchase Agreement") entered into by and among QuinStreet, HomeBuddy, the Shareholders of HomeBuddy (each a "Seller" and collectively, the "Sellers"), and Maxym Entin as the Shareholders' Representative. Pursuant to the terms of the Purchase Agreement, QuinStreet agreed to purchase from the Sellers all of the issued and outstanding equity securities of HomeBuddy. Prior to the Acquisition Date, on December 29, 2025, HomeBuddy paid a $6.0 million pro rata cash dividend inclusive of tax withholding, to its shareholders (the "Cash Sweep Dividend") in accordance with the Purchase Agreement, intended to distribute substantially all cash and cash-like positions on hand (other than an amount necessary to maintain a normalized level of working capital). At closing, QuinStreet paid $115.0 million in cash, subject to certain adjustments as provided in the Purchase Agreement. Pursuant to the Purchase Agreement, QuinStreet is obligated to pay $75.0 million in additional non-contingent post-closing payments (the "Anniversary Payments"), payable in equal annual installments over a four-year period. The Anniversary Payments are not subject to performance or operational milestones and become due solely with the passage of time. However, the Purchase Agreement permits QuinStreet to reduce each installment by certain allowable set-offs, including indemnification claims. No adjustment to the installments for set-offs or indemnification claims have been made in the pro forma financial information based on information available.

**Financing Event**

In connection with the Acquisition, QuinStreet entered into a new senior secured credit agreement (the "Financing Agreement") on January 2, 2026, by and among QuinStreet, as borrower, MUFG Bank, LTD., as administrative agent, and certain other lenders. The Financing Agreement provides for a $150.0 million revolving credit facility (the "Revolving Credit Facility"). The proceeds of the loans drawn under the Revolving Credit Facility were used to partially fund the acquisition of all of the issued and outstanding equity securities of HomeBuddy and may also be used for general working capital needs and other general corporate purposes of QuinStreet. On January 2, 2026, the Company borrowed $70.0 million under the Revolving Credit Facility in connection with the Acquisition.

The Revolving Credit Facility has a stated maturity date of January 2, 2031. Borrowings under the Revolving Credit Facility are secured by first-priority liens on substantially all assets of QuinStreet and certain subsidiaries, subject to certain exceptions. Interest on the borrowings under the Revolving Credit Facility is payable in arrears on the applicable interest payment date at an interest rate equal to, at QuinStreet's option, either (a) a SOFR-based rate (subject to a 0.00% per annum floor), plus an applicable margin of up to 2.75% per annum depending on the Consolidated Total Net Leverage Ratio (as defined in the Financing Agreement), or (b) a base rate (subject to a 0.00% per annum floor), plus an applicable margin of up to 1.75% per annum depending on the Consolidated Total Net Leverage Ratio. QuinStreet is also required to pay an unused commitment fee of up to 0.40% per annum on the unused portion of the Revolving Credit Facility, depending on the Consolidated Total Net Leverage Ratio.

**Other Information**

The unaudited pro forma condensed combined balance sheet ("pro forma balance sheet") assumes that the Acquisition occurred on September 30, 2025. The unaudited pro forma condensed combined statements of operations ("pro forma statements of operations") for the three months ended September 30, 2025, and for the year ended June 30, 2025 assumes that the Acquisition occurred as of July 1, 2024, and combines the historical results of QuinStreet and HomeBuddy giving pro forma effect for the periods then ended.

------

The adjustments in the pro forma financial information have been identified and presented to provide relevant information in accordance with generally accepted accounting principles in the United States ("GAAP") necessary for an illustrative understanding of the Acquisition. Certain non-recurring charges have been and may continue to be incurred in connection with the Acquisition, including among others, financial advisors, legal services and professional accounting services. These charges could affect the future results of QuinStreet in the period in which such charges are incurred; however, these costs are not expected to be incurred in any period beyond 12 months from the Acquisition Date. The pro forma statements of operations for the periods presented reflect the effects of these non-recurring transaction costs. The unaudited pro forma adjustments are believed by management to be necessary for a fair statement of QuinStreet's pro forma financial information, in accordance with the regulations of the Securities and Exchange Commission ("SEC").

The pro forma financial information is derived from the historical financial statements of QuinStreet and HomeBuddy, and should be read in conjunction with the following financial statements and accompanying notes:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•the historical unaudited condensed consolidated financial statements of QuinStreet for the three months ended September 30, 2025, included in its Quarterly Report on Form 10-Q filed with the SEC on November 7, 2025,

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•the historical audited consolidated financial statements of QuinStreet for the year ended June 30, 2025, included in its Annual Report on Form 10-K filed with the SEC on August 21, 2025,

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•the historical audited consolidated financial statements of HomeBuddy for the year ended December 31, 2024, that are included in Exhibit 99.1 of this Form 8-K/A, and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•the historical unaudited condensed consolidated financial statements of HomeBuddy for the nine months ended September 30, 2025, that are included in Exhibit 99.1 of this Form 8-K/A.

Assumptions underlying the pro forma adjustments are described in the accompanying notes, which should be read in conjunction with the unaudited pro forma condensed combined financial information. The transaction accounting and financing adjustments are based on available information and assumptions that the Company's management believes are reasonable. Such adjustments are estimates and actual experience may differ from expectations.

The Acquisition is subject to post-closing adjustments and adjustments related to the valuation of assets and liabilities acquired that have not yet been finalized. The pro forma adjustments are preliminary and have been made solely for the purpose of providing pro forma financial information as required by SEC rules. Differences between these preliminary estimates and the final balances may be material.

The pro forma financial information has been prepared for illustrative purposes only and are not necessarily indicative of what the combined company's financial position or results of operations would have been had the combination occurred as of the dates indicated. The pro forma financial information also should not be considered indicative of the future results of operations or financial position of QuinStreet.

**NOTES TO THE UNAUDITED PRO FORMA CONDENSED COMBINED FINANCIAL INFORMATION**

***(in thousands, except per share data)***

**Note 1: Basis of Presentation**

The pro forma financial information has been prepared in accordance with Article 11 of Regulation S-X, as amended. The historical financial information of QuinStreet and HomeBuddy has been adjusted to reflect transaction accounting and financing adjustments related to the Acquisition. The pro forma statements of operations include certain non-recurring costs incurred, or expected to be incurred, in connection with the Acquisition, including fees for financial advisors, legal services and professional accounting services. These costs may affect the future results of QuinStreet in the period in which they are incurred; however, these costs are not expected to be incurred beyond 12 months from the Acquisition Date. The pro forma statements of operations for the periods presented reflect the effects of these non-recurring transaction costs.

The Acquisition has been accounted for as a business combination in accordance with the acquisition method of accounting under GAAP, with QuinStreet as the acquirer of HomeBuddy. The acquisition method of accounting requires, among other things, that the assets acquired, and liabilities assumed in a business combination are measured and recognized at fair value as of the Acquisition Date. The excess of the purchase consideration over the fair value of assets acquired and liabilities assumed is allocated to goodwill. The purchase price allocation is preliminary and is based on management's current estimates and assumptions. The final purchase price allocation may differ materially from the preliminary allocation reflected in the transaction accounting adjustments, as additional information becomes available and further analyses are performed. As a result, the final purchase price allocation may include changes to the amounts assigned to identifiable intangible assets and goodwill.

The pro forma financial information includes certain reclassifications to conform HomeBuddy's historical accounting presentation to QuinStreet's accounting presentation. The actual results of operations of the combined company will likely differ, perhaps materially, from the pro forma amounts reflected herein due to a variety of factors. The Company believes that its assumptions and methodologies provide a reasonable basis for presenting the significant effects of the Acquisition based on information available to management at this time, and that the pro forma transaction accounting adjustments give effect to those assumptions and are properly applied in the pro forma financial information.

The pro forma financial information does not give effect to any anticipated synergies, operating efficiencies, tax savings, or cost savings that may be associated with the Acquisition and the related transactions. The income tax effects of the pro forma adjustments did not result in a significant impact to the pro forma statements of operations. The effective tax rate of the combined company could be significantly different from that presented in these unaudited pro forma financial statements depending on post-business combination activities, including legal entity restructuring, repatriation decisions, and the geographical mix of taxable income.

The pro forma balance sheet assumes that the Acquisition occurred on September 30, 2025. The pro forma statements of operations for the three months ended September 30, 2025, and for the year ended June 30, 2025 assumes that the Acquisition occurred as of July 1, 2024, and combines the historical results of QuinStreet and HomeBuddy giving pro forma effect for the periods then ended.

The pro forma financial information has been prepared for illustrative purposes only and are not necessarily indicative of what the combined company's financial position or results of operations would have been had the combination occurred as of the dates indicated. The pro forma financial information also should not be considered indicative of the future results of operations or financial position of QuinStreet.

***Fiscal Year End Difference***

QuinStreet and HomeBuddy have differing fiscal year ends of June 30 and December 31.

For purposes of the pro forma financial information, the periods presented for HomeBuddy are based on unaudited actual historical results for the three months ended September 30, 2025, and the twelve months ended June 30, 2025. The HomeBuddy periods presented align with QuinStreet's reporting periods and do not create quarter differences, overlaps, or gaps in the pro forma presentation. The pro forma financial information was prepared as follows:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•The pro forma balance sheet as of September 30, 2025, combines the historical unaudited condensed consolidated balance sheet of QuinStreet as of September 30, 2025, with the historical unaudited condensed consolidated balance sheet of HomeBuddy as of September 30, 2025.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•The pro forma statements of operations for the three months ended September 30, 2025, combines QuinStreet's historical unaudited condensed consolidated statement of operations for the three months ended September 30, 2025, with HomeBuddy's historical unaudited condensed consolidated statement of operations for the three months ended September 30, 2025. HomeBuddy's historical unaudited condensed consolidated statement of operations for the three months ended September 30, 2025 was prepared by subtracting the unaudited condensed consolidated statement of operations for the six months ended June 30, 2025 from the unaudited condensed consolidated statement of operations for the nine months ended September 30, 2025.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•The pro forma statements of operations for the year ended June 30, 2025, combines QuinStreet's audited consolidated statement of operations for the year ended June 30, 2025, with HomeBuddy's historical unaudited consolidated statement of operations for the twelve months ended June 30, 2025. HomeBuddy's historical unaudited consolidated statement of operations for the twelve months ended June 30, 2025 was prepared by adding the audited consolidated statement of operations for the year ended December 31, 2024, and the unaudited condensed consolidated statement of operations for the six months ended June 30, 2025, and subtracting the unaudited condensed consolidated statement of operations for the six months ended June 30, 2024.

**Note 2: Swiss Law to U.S. GAAP Conversion Adjustments**

HomeBuddy's historical consolidated balance sheet as of September 30, 2025, and statements of operations for the three months ended September 30, 2025, and for the twelve months ended June 30, 2025, have been prepared in accordance with Swiss law, which differs in certain material respects from U.S. GAAP. Although HomeBuddy is a Swiss entity, its reporting currency is the U.S. dollar. As a result, HomeBuddy's financial statements are presented in U.S. dollars, and all pro forma adjustments have been calculated in U.S. dollars. No currency translation adjustments are necessary for the preparation of the pro forma financial information.

During the preparation of this pro forma financial information, management performed a preliminary analysis of HomeBuddy's financial information to identify differences between Swiss law and U.S. GAAP, as well as differences in accounting policies compared to those of QuinStreet. The Company's assessment is ongoing; however, at the time of preparing the pro forma financial information, other than the adjustments made herein, the Company is not aware of any other material differences. Management will complete its review of HomeBuddy's financial information in order to determine if additional differences exist between Swiss law and U.S. GAAP, or if additional differences in accounting policies require adjustment to or reclassification of HomeBuddy's results. This will ensure conformity with QuinStreet's accounting policies and classifications, as required by acquisition accounting rules. Upon completion of its review, management may identify differences that, when conformed, could have a material impact on the pro forma financial information.

**Note 4: Preliminary Purchase Price Allocation**

The preliminary purchase consideration of $179.5 million is allocated to HomeBuddy's tangible and intangible assets acquired and liabilities assumed based on preliminary estimated fair values. These fair value assessments are based upon available information and certain assumptions, which QuinStreet believes are reasonable under the circumstances. Actual results may differ materially from the assumptions within the pro forma financial information.

The preliminary purchase consideration includes a $115.0 million cash payment, subject to certain adjustments as provided in the Purchase Agreement and $75.0 million of Anniversary Payments at a discount rate of 6.1%, payable in equal annual installments over a four-year period.

For purposes of the pro forma financial information, the preliminary calculation of the purchase consideration is as follows (in thousands):

---

| | |
|:---|:---|
| **Description** | **Amount** |
| Cash consideration | $114500 |
| Settlement of pre-existing relationships | (178) |
| Seller transaction expenses paid by the Company | 307 |
| Deferred cash consideration (Anniversary Payments) | 64889 |
| **Total preliminary purchase consideration** | $179518 |

---

As outlined in the Purchase Agreement, QuinStreet acquired all of the issued and outstanding Common Shares and Participation Shares of HomeBuddy from the Sellers in exchange for cash consideration.

For purposes of the pro forma financial information, the following table sets forth a preliminary allocation of the estimated purchase consideration assuming that the Acquisition occurred on September 30, 2025 (in thousands):

---

| | |
|:---|:---|
| Preliminary fair value of estimated purchase consideration | $179518 |
| **Assets:** |  |
| Cash and cash equivalents | 5138 |
| Accounts receivable | 6886 |
| Prepaid expenses and other assets | 2517 |
| Deferred tax assets | 290 |
| Intangible assets | 49500 |
| &nbsp;&nbsp;&nbsp;&nbsp;**Total Assets Acquired** | $64331 |
| **Liabilities:** |  |
| Accounts payable | 4463 |
| Accrued liabilities | 11000 |
| Other liabilities | 240 |
| Deferred tax liabilities | 6880 |
| &nbsp;&nbsp;&nbsp;&nbsp;**Total Liabilities Assumed** | $22583 |
| **Preliminary fair value of net assets acquired** | $41748 |
| **Estimated goodwill** | $137770 |

---

------

The preliminary estimates of the fair values of assets acquired and liabilities assumed have been determined by management of QuinStreet using publicly available benchmarking information, and other valuation methods, including the multi-period excess earnings method, relief-from-royalty method, with-and-without method, replacement cost method and cost approach. The intangible assets acquired include customer relationships, tradename and trademarks, non-competition agreements, and developed technology. The fair value of the customer relationships was determined using the multi-period excess earnings method. The fair value of the tradename and trademarks was determined using the relief-from-royalty method. The fair value of the non-competition agreement was determined using the with and without method. The fair value of the developed technology was determined using the replacement cost method. The purchase price allocation is preliminary and subject to change, as additional information becomes available and as additional analyses are performed. The difference between the preliminary total consideration and preliminary identifiable net assets acquired is recorded as estimated goodwill. Goodwill recognized in the Acquisition is not expected to be deductible for tax purposes. The final determination will be completed as soon as practicable, but no later than one year after the consummation of the Acquisition, and the final allocation could be materially different from the preliminary allocation used herein.

| 5(e) | Reflects the accrual of $2.3 million in accrued liabilities for transaction costs incurred by QuinStreet subsequent to September 30, 2025. |
| 5(f) | Reflects the elimination of HomeBuddy's historical equity balances, including share capital, treasury stock, and accumulated surplus. |
| 5(g) | Reflects income tax-related adjustments. The adjustment to deferred tax liability of $6.9 million, offset by the netting of the $0.3 million deferred tax asset, is associated with the incremental differences in the book and tax basis created from the preliminary purchase price allocation, primarily resulting from the preliminary fair value of intangible assets. QuinStreet has made no adjustments to HomeBuddy's historical realizability of deferred tax assets and will continue to assess such assets, recognizing that realizability could change upon consolidation. This estimate of deferred taxes was determined based on QuinStreet's expected ability to use HomeBuddy's other tax attributes in future periods, as well as the excess of the fair values of the acquired assets and liabilities over the tax basis of the assets and liabilities to be acquired.  |
| 5(h) | Reflects an adjustment to eliminate intercompany receivables and related payables arising from sales transactions between QuinStreet and HomeBuddy prior to the acquisition. |

|:---|:---|
| 6(a) | Reflects $0.4 million and $1.1 million of historical intercompany revenue elimination between HomeBuddy and QuinStreet for the three months ended September 30, 2025, and the year ended June 30, 2025, and the corresponding $0.4 million and $1.1 million of elimination of related cost of sales for the three months ended September 30, 2025, and the year ended June 30, 2025. |
| 6(b) | Reflects the elimination of $0.8 million and $2.2 million of HomeBuddy's historical amortization expense, and the recognition of $1.6 million and $6.6 million of new amortization expense, for the three months ended September 30, 2025, and the year ended June 30, 2025, related to the acquired identifiable intangible assets, based on estimated fair values as of the Acquisition Date. Amortization expense is calculated using the estimated fair value of each identifiable intangible asset and its associated estimated useful life consistent with QuinStreet's accounting policies. |

QuinStreet determined a preliminary fair value estimate of intangible assets based on a valuation conducted by management with the assistance of a third-party valuation specialist. The acquired intangible assets have been amortized to sales and marketing expenses using a straight-line method based on their estimated useful lives as if the Acquisition had been completed on July 1, 2024.

QuinStreet entered into continuation-of-service agreements with certain HomeBuddy executives for continued service post-acquisition. The retention bonuses vest over 6-, 12-, or 18-month periods, are contingent upon continued employment with the company and are treated as post-combination compensation expense. The amounts recognized are based on the months of service completed within the pro forma periods. Retention bonus expense is reflected in product development, general and administrative, and sales and marketing for each of the periods presented. |
| 6(d) | Reflects $2.3 million of transaction related costs, representing professional, advisory, and related fees incurred after September 30, 2025 in connection with the Acquisition. These costs are not expected to recur beyond 12 months after consummation of the Acquisition. |
| 6(e) | Reflects the estimated accretion of deferred purchase consideration of $0.7 million and $3.9 million for the three months ended September 30, 2025, and the year ended June 30, 2025. The deferred consideration was recorded at present value on the date of the Acquisition using a discount rate of 6.1%. The interest accretion on the deferred consideration was calculated using the effective interest method and assumes the obligation was outstanding for the whole of the periods presented. |

**Note 7: Financing Adjustments** 

QuinStreet entered into a $150.0 million Revolving Credit Facility on January 2, 2026. The adjustments related to the Revolving Credit Facility included in the pro forma balance sheet as of September 30, 2025, are as follows:

---

| | |
|:---|:---|
| 7(a) | Reflects the $70.0 million borrowed under the Revolving Credit Facility in connection with the Acquisition entered into by QuinStreet and is assumed to be outstanding as of September 30, 2025. The borrowing is classified as noncurrent debt based on the terms of the Financing Agreement and the stated maturity of January 2, 2031. |
| 7(b) | Reflects the capitalization of $1.7 million of debt issuance costs incurred in connection with the Revolving Credit Facility and the related cash payment at closing. In accordance with U.S. GAAP for line-of-credit arrangements, these costs are presented as a non-current asset and amortized on a straight-line basis over the five-year term of the Revolving Credit Facility. |

The adjustments related to the Revolving Credit Facility included in the pro forma statements of operations for the three months ended September 30, 2025, and the year ended June 30, 2025, are as follows:

---

| | |
|:---|:---|
| 7(c) | Reflects the estimated interest expense adjustment consisting of interest expense on borrowings under the Financing Agreement and the amortization of capitalized debt issuance costs. The borrowing-related interest and amortization are calculated assuming the related borrowings were outstanding for the three months ended September 30, 2025, and the year ended June 30, 2025. Borrowings under the Financing Agreement bear interest at a fluctuating rate per annum equal to the Term SOFR reference rate published by the CME Term SOFR administrator, plus an applicable margin depending on the Consolidated Total Net Leverage Ratio. For purposes of preparing the pro forma financial information, the assumed annual interest rate is 6.5% and the 0.25% annual commitment fee on the $80 million undrawn portion, were based on the rates applicable when the initial drawdown was made. A 125 basis point increase or decrease in the benchmark rate would result in a less than $0.1 million change in interest expense for the three months ended September 30, 2025, and the year ended June 30, 2025.
