Second Quarter 2025 and Post-Period Update

Strategic and Corporate Update

On May 13, 2025, we announced that the Board of Directors decided, following regulatory and market developments, to re-evaluate the previously proposed separation. As a result, strategic alternatives for the cell therapy business, including a potential divestiture, are being evaluated, with the goal of maximizing shareholder value:
- To facilitate this process, we established Galapagos Cell Therapeutics as a standalone entity within the Galapagos Group for consolidating all cell therapy activities.
- An update on the strategic process is expected to be provided in conjunction with the third-quarter 2025 results.
- Morgan Stanley is acting as financial advisor in connection with this process.
Our remaining business is focused on establishing a robust and novel pipeline of innovative medicines through transformational transactions. In recent months, we have taken decisive steps to advance this strategy by strengthening leadership and aligning internal capabilities to deliver on our goals:
- Executive leadership has been reinforced with the appointment of Henry Gosebruch as Chief Executive Officer, succeeding Dr. Paul Stoffels¹ , and Aaron Cox as Chief Financial Officer, succeeding Thad Huston.
- Ms. Sooin Kwon was appointed as Chief Business Officer (CBO) and Mr. Dan Grossman as Chief Strategy Officer (CStO), effective August 4, 2025. Recruitment for additional key leadership roles to further strengthen our management team is ongoing.
- Dawn Svoronos and Jane Griffiths have been appointed as Non-Executive Independent Directors by way of cooptation, effective July 28, 2025, replacing Peter Guenter and Simon Sturge, who will be stepping down.
- We transferred certain small molecule programs in oncology and immunology to Onco3R Therapeutics and in return, we will receive equity and future milestone-based considerations.
- We are actively exploring partnership opportunities for GLPG3667, a small molecule TYK2 inhibitor currently in Phase 3-enabling studies for systemic lupus erythematosus (SLE) and dermatomyositis (DM). Topline results from ongoing studies with GLPG3667 are expected during the first half of 2026.

Advancing the Cell Therapy Pipeline and Platform Under Current Planning, Subject to Ongoing Strategic Review

We presented new promising safety, efficacy and manufacturing data for GLPG5101 (CD19 CAR-T) from the completely enrolled cohort in relapsed/refractory (R/R) indolent non-Hodgkin lymphoma (iNHL) (Cohort 3) of the ongoing ATALANTA-1 Phase 1/2 study at ICML. As of the October 14, 2024 data cut-off, 34 patients with R/R iNHL (follicular lymphoma, FL, n=29; marginal zone lymphoma, MZL, n=5) underwent leukapheresis, of whom 32 (94%) received an infusion of GLPG5101. GLPG5101 demonstrated promising efficacy with robust and durable CAR-T cell expansion. A complete response (CR) rate of 97% (31/32) was observed with 100% of evaluable patients (10/10) being MRD negative at time of CR and the 12-month progression free survival (PFS) rate was 97%. GLPG5101 showed a favorable safety profile, with low rates of severe cytokine release syndrome (CRS) and immune effector cell-associated neurotoxicity syndrome (ICANS) observed, and no deaths reported.
We presented new promising pooled safety and manufacturing data from the ongoing ATALANTA-1 Phase 1/2 study for GLPG5101 in 64 patients with R/R NHL at EHA. As of the October 14, 2024 data cut-off date, of the 64 patients enrolled, 61 received treatment, resulting in a 5% attrition rate, significantly lower than industry benchmarks. 95% of patients were infused with fresh, stem-like early memory CD19 CAR-T cells, with 89% receiving treatment within seven days, avoiding the need for cryopreservation and cytotoxic bridging therapy. The data showed that GLPG5101 was well-tolerated with only a single case of Grade 3 CRS and Grade 3 ICANS reported in this heavily pretreated population.
GLPG5101 is being advanced toward pivotal development in mantle cell lymphoma (MCL), with enrollment expected to start in 2026. Following updates to the clinical study design, the Biologics License Application (BLA) filing is anticipated in 2028 with approval now expected in 2029.
We recently signed a collaboration agreement with CELLforCURE, by Seqens, to support the decentralized manufacturing of GLPG5101 for clinical development in Paris and the broader France area.
Our other cell therapy programs continue to progress including GLPG5301, a BCMA CAR-T candidate for relapsed/ refractory multiple myeloma; uza-cel, a MAGE A4 TCR-T candidate in head and neck cancer, in collaboration with Adaptimmune; and the early-stage next-generation CAR-T assets.

Financial Guidance

As of June 30, 2025, we had approximately €3.1 billion in cash and financial investments. Following recent leadership changes and as we are assessing strategic alternatives for the cell therapy business, we plan to provide an updated 2025 cash outlook at the time of our third-quarter 2025 results.

First-Half 2025 Financial Results

On May 13, 2025, we announced a strategic update regarding the company's intention to separate into two publicly traded entities. Since the initial announcement on January 8, 2025, we made significant progress in reorganizing our business towards the separation, which was expected by mid-2025, subject to shareholder approval and other customary conditions. However, following regulatory and market developments, our Board of Directors decided to re-evaluate the previously proposed separation. As such, we are exploring all strategic alternatives for the existing businesses, including the cell therapy business, with a focus on maximizing resources available for transformative business development transactions.

Total operating loss from continuing operations for the six months ended June 30, 2025, was €215.7 million, compared to an operating loss of €71.3 million for the six months ended June 30, 2024. This operating loss was negatively impacted by the strategic reorganization and intended separation, for a total of €131.6 million. This is reflected in severance costs of €47.5 million, costs for early termination of collaborations of €45.7 million, impairment on fixed assets related to small molecules activities of €12.0 million, deal costs of €16.6 million, €8.0 million accelerated noncash cost recognition for subscription right plans related to good leavers and €1.8 million other expenses.
Total net revenues for the six months ended June 30, 2025, amounted to €140.3 million, compared to €140.3 million for the six months ended June 30, 2024. The revenue recognition related to the exclusive access rights granted to Gilead for our drug discovery platform amounted to €115.1 million for the first six months of both 2025 and 2024. Our deferred income balance at June 30, 2025 includes €1.0 billion allocated to our drug discovery platform that will be recognized linearly over the remaining term of the Option, License and Collaboration Agreement (OLCA) with Gilead. We have recognized royalty income from Gilead for Jyseleca® for €5.6 million in the first six months of 2025 (compared to €6.1 million in the same period last year).
Cost of sales for the six months ended June 30, 2025, amounted to €18.4 million, compared to €19.1 million in the same period last year, and related to the supply of Jyseleca® to Alfasigma under the transition agreement. The related revenues are reported in total net revenues.
R&D expenses in the first six months of 2025 amounted to €278.0 million, compared to €145.2 million for the first six months of 2024. This increase was primarily explained by an increase in subcontracting cost from €64.6 million in the first half-year of 2024 to €141.0 million in the first half-year of 2025 due to increased costs for CAR-T and small molecule programs in oncology, and costs for early termination of collaborations. Personnel costs increased from €42.0 million in the first half of 2024 to €82.3 million for the same period this year due to severance costs. Depreciation and impairment expenses increased from €13.3 million in the first six months of 2024 to €32.2 million in the first six months of 2025 due to impairments on fixed assets related to small molecules activities.
S&M expenses amounted to €1.6 million in the first six months of 2025, compared to €7.1 million in the first six months of 2024. The decrease related to the reversal of a bad debt provision on Alfasigma receivables, a decrease in professional fees and other operating expenses.
G&A expenses amounted to €72.9 million in the first six months of 2025, compared to €56.8 million in the first six months of 2024. The increase in legal and professional fees, from €15.6 million in the first six months of 2024 to €20.8 million in the first six months of 2025 mainly related to deal costs, while the increase in personnel expenses of €11.7 million (from €25.4 million in the first six months of 2024 to €37.1 million in the same period this year) was due to higher severance costs.
Other operating income amounted to €14.9 million in the first six months of 2025, compared to €16.6 million for the same period last year, mainly driven by a reduction of recharges to Alfasigma.

Net financial loss in the first six months of 2025 amounted to €45.0 million (as compared to net financial income of €98.3 million in the same period last year) and consisted mainly of €21.8 million interest income (as compared to €49.4 million interest income in the same period last year) due to the decreased interest rates. Net financial loss in the first six months of 2025 also included €37.9 million of unrealized currency exchange loss on our cash and cash equivalents and current financial investments at amortized cost in U.S. dollar (as compared to €18.2 million unrealized currency exchange gain on cash and cash equivalents and current financial investments in the first six months of 2024), as a result of the

fluctuation of the U.S. dollar, and €27.2 million negative changes in fair value of current financial investments (€31.2 million positive changes in the same period last year).

We had €1.8 million of tax income for the first six months of 2025 (as compared to €1.1 million tax income for the same period last year).

Net loss from continuing operations for the first six months of 2025 was €259.0 million, compared to a net profit from continuing operations of €28.2 million for the same period last year.

Net loss from discontinued operations related to Jyseleca® amounted to €0.1 million for the first six months of 2025, compared to a net profit amounting to €71.0 million for the first six months of 2024. The operating profit from discontinued operations for the six months ended June 30, 2024, was mainly related to the gain on the sale of the Jyseleca® business to Alfasigma of €52.3 million.

We reported a net loss for the six months ended June 30, 2025, of €259.1 million, as compared to a net profit of €99.2 million for the six months ended June 30, 2024.

Cash, Cash Equivalents and Financial Investments

Cash and cash equivalents and financial investments totaled €3,091.5 million as of June 30, 2025 (€3,317.8 million as of 31 December 2024).

On June 30, 2025, our cash and cash equivalents and current financial investments included \$2,156.2 million held in U.S. dollars (\$726.9 million on December 31, 2024) which could generate foreign exchange gains or losses in our financial results in accordance with the fluctuation of the EUR/U.S. dollar exchange rate as our functional currency is EUR.

A net decrease of €226.3 million in cash and cash equivalents and financial investments was recorded during the first six months of 2025, compared to a net decrease of €254.1 million during the first six months of 2024.

This net decrease was composed of (i) €91.5 million of operational cash burn, (ii) €122.7 million of negative exchange rate differences, negative changes in fair value of current financial investments and variation in accrued interest income, (iii) €20.0 million loans and advances given to third parties, partly offset by (iv) €7.9 million of net cash in related to the sale/ acquisition of subsidiaries.

The operational cash burn (or operational cash flow if this liquidity measure is positive) is a financial measure that is not calculated in accordance with IFRS. Operational cash burn/cash flow is defined as the increase or decrease in our cash and cash equivalents (excluding the effect of exchange rate differences on cash and cash equivalents), minus:

1. the net proceeds, if any, from share capital and share premium increases included in the net cash flows generated from/used in (–) financing activities.
1. the net proceeds or cash used, if any, in acquisitions or disposals of businesses; the acquisition of equity investments held at fair value; the movement in restricted cash and movement in financial investments, if any, the loans and advances given to third parties, if any, included in the net cash flows generated from/used in (–) investing activities.
1. the cash used for other liabilities related to the acquisition of businesses, if any, included in the net cash flows generated from/used in (–) operating activities.

This alternative liquidity measure is in our view an important metric for a biotech company in the development stage.

The following table provides a reconciliation of the operational cash burn:

Notes to the Unaudited Condensed Consolidated Interim Financial Statements for the First Six Months of 2025

Basis of Preparation

These condensed consolidated interim financial statements have been prepared in accordance with IAS 34 'Interim Financial Reporting' as adopted by the European Union. The condensed consolidated interim financial statements do not contain all information required for an annual report and should therefore be read in conjunction with our Annual Report 2024.

Material Accounting Policies

There were no significant changes in accounting policies applied by us in these condensed consolidated interim financial statements compared to those used in the most recent annual consolidated financial statements of December 31, 2024.

New standards and interpretations applicable for the annual period beginning on January 1, 2025 did not have any material impact on our condensed consolidated interim financial statements.

We have not early adopted any other standard, interpretation, or amendment that has been issued but is not yet effective. We are currently still assessing the impact of these new accounting standards and amendments that are not yet effective, but we expect no standard to have a material impact on our financial statements in the period of initial application except for the effect of IFRS 18 (effective for the period beginning January 1, 2027) as mentioned below.

IFRS 18 Presentation and disclosure in Financial Statements, which was issued by the IASB in April 2024 supersedes IAS 1 and will result in major consequential amendments to IFRS Accounting Standards including IAS8 Basis of Preparation of Financial Statements (renamed from Accounting Policies, Changes in Accounting Estimates and Errors). Even though IFRS 18 will not have any effect on the recognition and measurement of items in the condensed consolidated interim financial statements, it is expected to have a significant effect on the presentation and disclosure of certain items. These changes include categorization and sub-totals in the statement of profit or loss, aggregation/disaggregation and labelling of information, and disclosure of management-defined performance measures.

Summary of Significant Transactions

Strategic Update regarding the proposed Separation

On May 13, 2025, we announced a strategic update regarding the company's intention to separate into two publicly traded entities. Since the initial announcement on January 8, 2025, we made significant progress in reorganizing our business towards the separation, which was expected by mid-2025, subject to shareholder approval and other customary conditions. However, following regulatory and market developments, our Board of Directors has decided to re-evaluate the previously proposed separation and will explore all strategic alternatives for the existing businesses, including the cell therapy business, with a focus on maximizing resources available for transformative business development transactions.

In the first half of 2025, we incurred costs for the strategic reorganization and intended separation, for a total of €131.6 million. This is reflected in severance costs of €47.5 million, costs for early termination of collaborations of €45.7 million, impairment on fixed assets related to small molecules activities of €12.0 million , deal costs of €16.6 million, €8.0 million accelerated non- cash cost recognition for subscription right plans related to good leavers and €1.8 million other expenses.

Transfer of Assets and Financing Agreement with Onco3R Therapeutics BV

In April 2025, we and Onco3R Therapeutics (Onco3R) signed an agreement under which multiple small molecule immunology and oncology assets, including Phase 1-ready SIK3 inhibitor, have been sold to Onco3R. Under the terms of the agreement, we will participate in Onco3R's start-up capital via a convertible loan facility of €20 million, which will convert during the next equity financing round.

Onco3R is committed to using commercially reasonable efforts to develop and commercialize these assets.

This convertible loan facility is presented in the line "Convertible loan" in our statement of financial position and is measured at fair value through profit or loss. As per June 30, 2025, the only fair value change recognized is related to the capitalized interest.

In exchange for the transfer of these assets, we are entitled to a contingent consideration. The contingent consideration is recognized as a financial asset recognized at fair value through profit or loss. On June 30, 2025, the fair value is valued by management at zero, based on the very-early stage of the transferred assets. The fair values are reviewed at each reporting date and any changes are reflected in our consolidated income statement. An impairment was recorded for assets transferred to Onco3R Therapeutics (€1.7 million).

Critical Accounting Judgements and Key Sources of Estimation Uncertainty

There were no significant changes in our critical accounting judgements and key sources of estimations uncertainty compared to those used in the most recent annual consolidated financial statements of December 31, 2024, except for the following new critical accounting judgements and key sources of estimation uncertainty.

Determination of fair value of convertible loan receivable

As there is no active market for the convertible loan and no reference share value is readily available of Onco3R, which is a very early-stage R&D organization at the moment, we establish the fair value by using other valuation techniques. The fair value has been determined mainly by reference to the initial transaction price and adjusted as necessary for impairment and revaluations with reference to capitalized interests, relevant available information and recent financing rounds.

The inputs used are categorized as Level 3 inputs.

Determination of restructuring provision

On June 30, 2025, as a result of the strategic reorganization, we recorded a provision for the early termination of collaborations. The provision is estimated based on the total amount of undelivered open purchase commitments, ongoing negotiations with collaboration partners, and confirmed potential exposure provided by our legal advisor.

Details of the Unaudited Condensed Consolidated Interim Results

Collaboration revenues

The following table summarizes our collaboration revenues for the six months ended June 30, 2025 and 2024:

		Over Point time in time	Six months ended June 30

Operating costs and other operating income

Operating costs

Research and development expenditure

The following table summarizes our research and development expenditure for the six months ended June 30, 2025 and 2024:

		Six months ended June 30
(thousands of €)	2025	2024
Personnel costs	(82,282)	(42,040)

Other operating expenses	(10,244)	(7,954)
Total research and development expenses	(278,027)	(145,225)

Subcontracting costs increased mainly related to CAR-T and small molecule programs in oncology, and costs for early termination of collaboration agreements. Personnel expenses increased due to severance costs, the increase in depreciation and impairment costs was due to impairment costs related to small molecules assets, of which €10.8 million was recorded on installations and machinery.

The table below summarizes our R&D expenditure for the six months ended June 30, 2025 and 2024, broken down by program.

	Six months ended June 30
(thousands of €)	2025	2024

Other discovery programs	(136,689)	(54,946)
Total research and development expenses	(278,027)	(145,225)

Costs for other discovery programs increased in the first half of 2025 compared to the same period last year, primarily due to the restructuring costs of the small molecule business.

R&D incentives income	11,946	10,620
Other	2,929	4,694

Cash position

Cash and cash equivalents and financial investments totaled €3,091.5 million on June 30, 2025 (€3,317.8 million on December 31, 2024).

Cash and cash equivalents and financial investments comprised cash at banks, term deposits, treasury bills (nil at June 30, 2025) and money market funds. Our cash management strategy monitors and optimizes our liquidity position. Our cash management strategy allows short-term deposits with an original maturity exceeding three months while monitoring all liquidity aspects.

All cash and cash equivalents are available upon maximum three months' notice period and without significant penalty. Cash at banks were mainly composed of current accounts. Our credit risk is mitigated by selecting a panel of highly rated financial institutions for our deposits.

Current financial investments comprised €751.6 million of term deposits which all had an original maturity longer than three months and which are not available on demand within three months. Our current financial investments also comprised money market funds and treasury bills. Our portfolio of treasury bills contained only AAA rated paper, issued by France, Belgium and Europe. Our money market funds portfolio consists of AAA short-term money market funds with a diversified and highly rated underlying portfolio managed by established fund management companies with a proven track record.

Financial risk management

The following table summarizes the categories of financial assets and liabilities held at fair value:

		June 30	December 31 2024
(thousands of €)	Fair value hierarchy	2025
Financial assets held at fair value through other comprehensive income
Equity instruments	Level 3	46,928	52,941
Financial assets held at fair value through profit or loss
Contingent consideration receivable	Level 3	57,606	47,207
Financial investments	Level 1	2,268,258	1,484,599
Convertible loan	Level 3	20,348	–
Financial liabilities held at fair value through profit or loss
Contingent consideration related to milestones CellPoint	Level 3	21,238	20,576

The decrease of the fair value of the equity instruments, which is due to exchange losses, of €6.0 million is reflected in the other reserves (other comprehensive income) in the consolidated equity. The valuation of all our equity investments is based on Level 3 assumptions as it includes investments in non-quoted companies. These investments are valued initially at fair value through the established purchase price between a willing buyer and seller. Subsequent valuation is based on internal and external evidence such as information from recent financing rounds, scientific updates and other valuation techniques.

The contingent consideration receivable relates to fair value of the future earn-outs to be obtained from Alfasigma for the sale of Jyseleca®. €7.0 million is presented on the line "Trade and other receivables" and €50.6 million is presented on the line "non-current contingent consideration receivable". The total potential amount consists of sales-based milestone payments totaling €120 million and mid-single to mid-double-digit royalties on European sales. The valuation is based on Level 3 assumptions based on our best estimate of the expected earn-outs and sales milestones in the future, considering probability adjusted sales forecasts of Jyseleca® discounted using an appropriate discount rate. The fair value is reviewed at each reporting date and any changes are reflected in our consolidated income statement, in the line 'Net profit/loss (-) from discontinued operations, net of tax'. On June 30, 2025, the fair value of the future earn-outs was increased based on an adjustment of the sales forecasts of Jyseleca® in Europe considering the evolution of the actual net sales. A change in expected sales by 15% would result in a change of €18.0 million in the total contingent consideration receivable on June 30, 2025.

The contingent consideration arrangement relating to the acquisition of CellPoint requires us to pay the former owners of CellPoint additional considerations up to €100.0 million. This amount is due when certain sequential development (€20.0 million), regulatory (€30.0 million) and sales-based (€50.0 million) milestones would be achieved. Total fair value at June 30, 2025 of these milestones amounted to €21.2 million. The fair value measurement is based on significant inputs that are not observable in the market, which are classified as Level 3 inputs. Key assumptions in the valuation at June 30, 2025 include a discount rate of 13.50% for the first two milestones and a discount rate of 14% for the third milestone, an appropriate probability of success of reaching these milestones and expected timing of these milestones. A change in probabilities of success of each milestone by 5 percentage points would result in a change of €3.0 million in the total contingent consideration liability on June 30, 2025. As per June 30, 2025, changes were made to the key assumptions as compared to December 31, 2024 regarding the discount rate and the expected timing of the milestones. This impact, together with the discounting effect, was recognized in the financial results.

We refer to critical accounting judgements and key sources of estimation uncertainty for details about the fair value of the convertible loan.

Off-balance Sheet Arrangements

Contractual obligations and commitments

We have certain purchase commitments principally with CRO subcontractors and certain collaboration partners.

On June 30, 2025, we had outstanding obligations for purchase commitments, which become due as follows:

(thousands of €)	Total	Less than 1 year	1 – 3 years	3 – 5 years	More than 5 years
Purchase commitments	179,311	134,236	37,941	6,524	610

We refer to our Annual Report 2024 for additional information on our contingent contractual obligations.

Related Party Transactions

On April 29 2025, we held our Annual Shareholders' Meeting ("AGM"). The AGM approved the appointment of Mr. Oleg Nodelman as Non-Executive Director for a period of four years.

On May 13, 2025, we announced the appointment of Mr. Henry Gosebruch as Chief Executive Officer, effective immediately, succeeding Stoffels IMC BV, permanently represented by Dr. Paul Stoffels, who announced his retirement in April 2025. The related agreements have been entered into in line with our Remuneration Policy.

On May 27, 2025, the new CEO, Mr. Henry Gosebruch, was offered new subscription rights under Subscription Right Plan 2025 (A), subject to acceptance. The subscription rights have an exercise term of eight years as of the date of the notarial deed enacting the acceptance of the subscription rights. The exercise price of the subscription rights is €25.64 (the closing price of the Galapagos share on Euronext Brussels and Amsterdam on the date of the offer). Each subscription right gives the right to subscribe for one new Galapagos share. The subscription rights can in principle not be exercised prior to June 12, 2028.

On June 16 and June 23, 2025, certain members of the Executive Committee were offered new restricted stock units ("RSUs"). The RSUs were offered for no consideration. Each RSU represents the right to receive, at Galapagos' discretion, one Galapagos share or a payment in cash of an amount equivalent to the volume-weighted average price of the Galapagos share on Euronext Brussels over the 30-calendar day period preceding the relevant vesting date. The first RSU grant has a cliff vesting date on May 1, 2028 and the second RSU grant a four-year vesting period, with 25% vesting each year and a first vesting date on May 1, 2026. For the members of the Executive Committee, any vesting prior to the third anniversary of the offer date will always give rise to a payment in cash rather than a delivery of shares.

The table below sets forth the number of subscription rights offered and accepted under Subscription Right Plan 2025 (A) and the number of RSUs offered to each member of the Executive Committee during the first six months of 2025:

Name	Title	Number of 2025 subscription rights accepted	Number of 2025 RSUs offered
Henry Gosebruch	CEO	925,000	300,000(1)
Valeria Cnossen	General Counsel		20,636
Annelies Missotten	Chief Human Resources Officer		9,288
(2) Aaron Cox	Chief Financial Officer

(1) These RSUs have already been accepted.

(2) Appointed as CFO as of July 7, 2025.

On June 23, 2025, we announced the appointment of Mr. Aaron Cox as Chief Financial Officer, effective July 7, 2025. Mr. Cox succeeds Thad Huston, who will remain with us through July 31, 2025. The related agreements have been entered into in line with our Remuneration Policy.

During the first six months of 2025, other than as disclosed in the paragraph above, there were no changes to related party transactions disclosed in the 2024 annual report that potentially had a material impact on our financials of the first six months of 2025.

Events after the End of the Reporting Period

There were no adjusting events nor material non-adjusting events to be reported.

Approval of Interim Financial Statements

The interim financial statements were approved by the Board of Directors on July 22, 2025.

REPORT OF THE STATUTORY AUDITOR

Statutory Auditor's Report to the Board of Directors of Galapagos NV on the Review of Consolidated Interim Financial Information for the Six-Month Period Ended 30 June 2025

Introduction

We have reviewed the accompanying consolidated statement of financial position of Galapagos NV as of 30 June 2025 and the related consolidated statements of income and comprehensive income/loss (-), cash flows and changes in equity for the six-month period then ended, as well as the explanatory notes. The Board of Directors is responsible for the preparation and presentation of this consolidated interim financial information in accordance with IAS 34 "Interim Financial Reporting", as adopted by the European Union. Our responsibility is to express a conclusion on this consolidated interim financial information based on our review.

Scope of review

We conducted our review in accordance with International Standard on Review Engagements 2410, "Review of Interim Financial Information Performed by the Independent Auditor of the Entity". A review of interim financial information consists of making inquiries, primarily of persons responsible for financial and accounting matters, and applying analytical and other review procedures. A review is substantially less in scope than an audit conducted in accordance with International Standards on Auditing and consequently does not enable us to obtain assurance that we would become aware of all significant matters that might be identified in an audit. Accordingly, we do not express an audit opinion.

Conclusion

Based on our review, nothing has come to our attention that causes us to believe that the accompanying consolidated interim financial information is not prepared, in all material respects, in accordance with IAS 34 "Interim Financial Reporting", as adopted by the European Union.
