Surgical growth reflects strength in international markets

For the second quarter of 2024, Surgical net sales, which include implantables, consumables and equipment/other, were $1.4 billion, an increase of 3% on a reported basis and 6% on a constant currency basis versus the second quarter of 2023.

•Implantables net sales were $464 million, an increase of 6%. Excluding unfavorable currency impacts of 3%, implantables net sales increased 9% in constant currency. Growth was led by advanced technology intraocular lenses in international markets.

•Consumables net sales were $736 million, an increase of 3%, driven by cataract and vitreoretinal consumables, particularly in international markets, and price increases. Excluding unfavorable currency impacts of 2%, consumables net sales increased 5% constant currency.

•Equipment/other net sales were $223 million, a decrease of 3%. Excluding unfavorable currency impacts of 2%, equipment/other net sales decreased 1% constant currency as the prior year period benefited from strong demand for cataract equipment in international markets.

For the first half of 2024, Surgical net sales were $2.8 billion, an increase of 3% on a reported basis and 6% on a constant currency basis versus the first half of 2023.

Vision Care growth reflects strength in contact lenses

For the second quarter of 2024, Vision Care net sales, which include contact lenses and ocular health, were $1.1 billion, an increase of 4% on a reported basis and 6% on a constant currency basis, versus the second quarter of 2023.

•Contact lenses net sales were $636 million, an increase of 7%, driven by product innovation, including our toric and multifocal modalities, and price increases. Growth was partially offset by unfavorable currency impacts of 2%. Contact lenses net sales increased 9% constant currency.

•Ocular health net sales were $423 million, a decrease of 1%. Excluding unfavorable currency impacts of 3%, ocular health net sales increased 2% in constant currency. This constant currency growth was primarily driven by the portfolio of eye drops, including continued strength from the Systane family of artificial tears. Growth was partially offset by a decline of 4% due to contact lens care, primarily driven by the prior year period benefit from the recovery from supply chain challenges.

For the first half of 2024, Vision Care net sales were $2.2 billion, an increase of 6% on a reported basis and 8% on a constant currency basis versus the first half of 2023.

Operating income

Second-quarter 2024 operating income was $318 million, compared to $270 million in the prior year period. Operating margin increased 1.6 percentage points, reflecting improved underlying operating leverage from higher sales. The prior year period included $26 million for the transformation program which was completed in the fourth quarter of 2023. The second quarter of 2024 included significantly higher inventory provisions in Vision Care due to a supplier-related quality issue which resulted in a negative impact of $30 million or 1.2 percentage points to operating margin. Operating margin was also impacted by higher costs of inventory in Surgical and a negative 1.0 percentage point impact from currency. Operating margin increased 2.6 percentage points on a constant currency basis.

Adjustments to arrive at core operating income2 in the current year period were $173 million, mainly due to $165 million of amortization. Excluding these and other adjustments, second-quarter 2024 core operating income was $491 million.

Second-quarter 2024 core operating margin was 19.8%. Core operating margin decreased 0.1 percentage point, including a negative 0.8 percentage point impact from currency. Core operating margin increased 0.7 percentage points on a constant currency basis, reflecting improved underlying operating leverage from higher sales. The second quarter of 2024 included significantly higher inventory provisions in Vision Care due to a supplier-related quality issue which resulted in a negative impact of $30 million or 1.2 percentage points to core operating margin. There were also higher costs of inventory in Surgical.

First-half 2024 operating income was $686 million and operating margin was 13.9%, which increased 2.5 percentage points on a reported basis and 3.7 percentage points on a constant currency basis. Adjustments to arrive at core operating income in the current year period were $342 million, mainly due to $331 million of amortization. Excluding these and other adjustments, core operating income was $1.0 billion.

First-half 2024 core operating margin was 20.9%, an increase of 0.6 percentage points on a reported basis and 1.6 percentage points on a constant currency basis.

Diluted earnings per share (EPS)

Second-quarter 2024 diluted earnings per share of $0.45 increased 32%, or 47% on a constant currency basis. Core diluted earnings per share of $0.74 increased 7%, or 15% on a constant currency basis.

First-half 2024 diluted earnings per share of $0.95 increased 38%, or 55% on a constant currency basis. Core diluted earnings per share for the first six months of $1.52 increased 9%, or 18% on a constant currency basis.

Cash flow highlights

The Company ended the first six months of 2024 with a cash position of $1.4 billion. Net cash flows from operating activities amounted to $871 million in the first six months of 2024, compared to $410 million in the prior year period. The current year period includes increased collections associated with higher sales, lower taxes paid due to timing of payments and lower transformation payments following completion of the transformation program in the fourth quarter of 2023, partially offset by associate short-term incentive payments, which generally occur in the first quarter and were higher than in the prior year period, and increased payments for operating expenses. The prior period included a cash outflow for a legal settlement. Both periods were impacted by changes in net working capital.

Free cash flow was an inflow of $667 million in the first six months of 2024, compared to $189 million in the prior year period, primarily due to increased cash flows from operating activities.

Cautionary Note Regarding Forward-Looking Statements

This document contains, and our officers and representatives may from time to time make, certain “forward-looking statements” within the meaning of the safe harbor provisions of the US Private Securities Litigation Reform Act of 1995. Forward-looking statements can be identified by words such as “anticipate,” “intend,” “commitment,” “look forward,” “maintain,” “plan,” “goal,” “seek,” “target,” “assume,” “believe,” “project,” “estimate,” “expect,” “strategy,” “future,” “likely,” “may,” “should,” “will” and similar references to future periods. Examples of forward-looking statements include, among others, statements we make regarding our liquidity, revenue, gross margin, operating margin, effective tax rate, foreign currency exchange movements, earnings per share, our plans and decisions relating to various capital expenditures, capital allocation priorities and other discretionary items such as our market growth assumptions, our social impact and sustainability plans, targets, goals and expectations, and generally, our expectations concerning our future performance.

Forward-looking statements are neither historical facts nor assurances of future performance. Instead, they are based only on our current beliefs, expectations and assumptions regarding the future of our business, future plans and strategies, and other future conditions. Because forward-looking statements relate to the future, they are subject to inherent uncertainties and risks that are difficult to predict such as: cybersecurity breaches or other disruptions of our information technology systems; compliance with data privacy, identity protection and information security laws, particularly with the increased use of artificial intelligence; the impact of a disruption in our global supply chain or important facilities, particularly when we single-source or rely on limited sources of supply; our ability to forecast sales demand and manage our inventory levels and the changing buying patterns of our customers; our ability to manage social impact and sustainability matters; our reliance on outsourcing key business functions; global and regional economic, financial, monetary, legal, tax, political and social change; our success in completing and integrating strategic acquisitions; the success of our research and development efforts, including our ability to innovate to compete effectively; our ability to comply with the US Foreign Corrupt Practices Act of 1977 and other applicable anti-corruption laws; pricing pressure from changes in third party payor coverage and reimbursement methodologies; our ability to properly educate and train healthcare providers on our products; our ability to protect our intellectual property; our ability to comply with all laws to which we may be subject; the ability to obtain regulatory clearance and approval of our products as well as compliance with any post-approval obligations, including quality control of our manufacturing; the effect of product recalls or voluntary market withdrawals; the accuracy of our accounting estimates and assumptions, including pension and other post-employment benefit plan obligations and the carrying value of intangible assets; the impact of unauthorized importation of our products from countries with lower prices to countries with higher prices; our ability to service our debt obligations; the need for additional financing through the issuance of debt or equity; the effects of litigation, including product liability lawsuits and governmental investigations; supply constraints and increases in the cost of energy; our ability to attract and retain qualified personnel; legislative, tax and regulatory reform; the impact of being listed on two stock exchanges; the ability to declare and pay dividends; the different rights afforded to our shareholders as a Swiss corporation compared to a US corporation; the effect of maintaining or losing our foreign private issuer status under US securities laws; and the ability to enforce US judgments against Swiss corporations.

Additional factors are discussed in our filings with the United States Securities and Exchange Commission, including our Form 20-F. Should one or more of these uncertainties or risks materialize, or should underlying assumptions prove incorrect, actual results may vary materially from those anticipated. Therefore, you should not rely on any of these forward-looking statements. Forward-looking statements in this document speak only as of the date of its filing, and we assume no obligation to update forward-looking statements as a result of new information, future events or otherwise.

Intellectual Property

This report may contain references to our proprietary intellectual property. All product names appearing in italics or ALL CAPS are trademarks owned by or licensed to Alcon Inc. Product names identified by a "®" or a "™" are trademarks that are not owned by or licensed to Alcon or its subsidiaries and are the property of their respective owners.

Non-IFRS measures as defined by the Company

Alcon uses certain non-IFRS metrics when measuring performance, including when measuring current period results against prior periods, including core results, percentage changes measured in constant currency and free cash flow.

Because of their non-standardized definitions, the non-IFRS measures (unlike IFRS measures) may not be comparable to the calculation of similar measures of other companies. These supplemental non-IFRS measures are presented solely to permit investors to more fully understand how Alcon management assesses underlying performance. These supplemental non-IFRS measures are not, and should not be viewed as, a substitute for IFRS measures.

Core results

Alcon core results, including core operating income and core net income, exclude all amortization and impairment charges of intangible assets, excluding software, net gains and losses on fund investments and equity securities valued at fair value through profit and loss ("FVPL"), fair value adjustments of financial assets in the form of options to acquire a company carried at FVPL and certain acquisition related items. The following items that exceed a threshold of $10 million and are deemed exceptional are also excluded from core results: integration and divestment related income and expenses, divestment gains and losses, restructuring charges/releases and related items, legal related items, gains/losses on early extinguishment of debt or debt modifications, past service costs for post-employment benefit plans, impairments of property, plant and equipment and software, as well as income and expense items that management deems exceptional and that are or are expected to accumulate within the year to be over a $10 million threshold.

Taxes on the adjustments between IFRS and core results take into account, for each individual item included in the adjustment, the tax rate that will finally be applicable to the item based on the jurisdiction where the adjustment will finally have a tax impact. Generally, this results in amortization and impairment of intangible assets and acquisition-related restructuring and integration items having a full tax impact. There is usually a tax impact on other items, although this is not always the case for items arising from legal settlements in certain jurisdictions.

Alcon believes that investor understanding of its performance is enhanced by disclosing core measures of performance because, since they exclude items that can vary significantly from period to period, the core measures enable a helpful comparison of business performance across periods. For this same reason, Alcon uses these core measures in addition to IFRS and other measures as important factors in assessing its performance.

A limitation of the core measures is that they provide a view of Alcon operations without including all events during a period, such as the effects of an acquisition, divestment, or amortization/impairments of purchased intangible assets and restructurings.

Constant currency

Changes in the relative values of non-US currencies to the US dollar can affect Alcon's financial results and financial position. To provide additional information that may be useful to investors, including changes in sales volume, we present information about changes in our net sales and various values relating to operating and net income that are adjusted for such foreign currency effects.

Constant currency calculations have the goal of eliminating two exchange rate effects so that an estimate can be made of underlying changes in the Consolidated Income Statement excluding:

•the impact of translating the income statements of consolidated entities from their non-US dollar functional currencies to the US dollar; and

•the impact of exchange rate movements on the major transactions of consolidated entities performed in currencies other than their functional currency.

Alcon calculates constant currency measures by translating the current year's foreign currency values for sales and other income statement items into US dollars, using the average exchange rates from the historical comparative period and comparing them to the values from the historical comparative period in US dollars.

Free cash flow

Alcon defines free cash flow as net cash flows from operating activities less cash flow associated with the purchase or sale of property, plant and equipment. Free cash flow is presented as additional information because Alcon management believes it is a useful supplemental indicator of Alcon's ability to operate without reliance on additional borrowing or use of existing cash. Free cash flow is not intended to be a substitute measure for net cash flows from operating activities as determined under IFRS.

Growth rate and margin calculations

For ease of understanding, Alcon uses a sign convention for its growth rates such that a reduction in operating expenses or losses compared to the prior year is shown as a positive growth.

Gross margins, operating income margins and core operating income margins are calculated based upon net sales to third parties unless otherwise noted.

Reconciliation of guidance for forward-looking non-IFRS measures

The forward-looking guidance included in this press release cannot be reconciled to the comparable IFRS measures without unreasonable efforts, because we are not able to predict with reasonable certainty the ultimate amount or nature of exceptional items in the fiscal year. These items are uncertain, depend on many factors and could have a material impact on our IFRS results for the guidance period.

Second quarter

Interest expense

Interest expense was $50 million, broadly in line with the prior year period.

Other financial income & expense

Other financial income & expense was a net benefit of $12 million, compared to a net expense of $9 million in the prior year period. The change was primarily driven by an increase in interest income and lower foreign currency exchange losses.

Taxes

Tax expense was $57 million, compared to $44 million in the prior year period. The average tax rate was 20.4%, compared to 20.7% in the prior year period. The decrease in average tax rate is primarily driven by a more favorable mix of pre-tax income/(loss) across geographical tax jurisdictions and higher benefits from the build of inventory in certain international markets in the current year period, partially offset by discrete tax benefits in the prior year period.

Adjustments to arrive at core tax expense in the current year period were $29 million, compared to $37 million in the prior year period, for the tax effect associated with operating income core adjustments.

Core tax expense was $86 million, compared to $81 million in the prior year period. The average core tax rate was 19.0%, compared to 19.2% in the prior year period. The decrease in average tax rate is primarily driven by a more favorable mix of pre-tax income/(loss) across geographical tax jurisdictions and higher benefits from the build of inventory in certain international markets in the current year period, partially offset by discrete tax benefits in the prior year period.

Net income and earnings per share

Net income was $223 million, compared to $169 million in the prior year period, primarily due to higher operating income and a net benefit in other financial income & expense, partially offset by higher tax expense. The associated basic and diluted earnings per share were $0.45, compared to basic and diluted earnings per share of $0.34 in the prior year period.

Core net income was $367 million, compared to $341 million in the prior year period, primarily due to higher core operating income and a net benefit in other financial income & expense, partially offset by higher core tax expense. The associated core basic and diluted earnings per share were $0.74, compared to core basic and diluted earnings per share of $0.69 in the prior year period.

First half

Interest expense

Interest expense was $95 million, in line with the prior year period.

Other financial income & expense

Other financial income & expense was a net benefit of $24 million, compared to a net expense of $17 million in the prior year period. The change was primarily driven by an increase in interest income and lower foreign currency exchange losses.

Taxes

Tax expense was $144 million, compared to $83 million in the prior year period. The average tax rate was 23.4%, compared to 19.5% in the prior year period. The increase in average tax rate is primarily driven by a net expense of $13 million from discrete tax items in the current year period, compared to discrete tax benefits in the prior year period. The prior year period also benefited from the deduction of a statutory expense in Switzerland. Increases to the average tax rate were partially offset by a more favorable mix of pre-tax income/(loss) across geographical tax jurisdictions in the current year period.

Adjustments to arrive at core tax expense in the current year period were $59 million, compared to $76 million in the prior year period, for the tax effect associated with operating income core adjustments.

Core tax expense was $203 million, compared to $159 million in the prior year period. The average core tax rate was 21.2%, compared to 18.8% in the prior year period. The increase in average tax rate is primarily driven by a net expense of $13 million from discrete tax items in the current year period, compared to discrete tax benefits in the prior year period. The prior year period also benefited from the deduction of a statutory expense in Switzerland. Increases to the average tax rate were partially offset by a more favorable mix of pre-tax income/(loss) across geographical tax jurisdictions in the current year period.

Net income and earnings per share

Net income was $471 million, compared to $343 million in the prior year period, primarily due to higher operating income and a net benefit in other financial income & expense, partially offset by higher tax expense. The associated basic and diluted earnings per share were $0.95, compared to basic and diluted earnings per share of $0.70 and $0.69, respectively, in the prior year period.

Core net income was $754 million, compared to $688 million in the prior year period, primarily due to higher core operating income and a net benefit in other financial income & expense, partially offset by higher core tax expense. The associated core basic and diluted earnings per share were $1.53 and $1.52, respectively, compared to core basic and diluted earnings per share of $1.40 and $1.39, respectively, in the prior year period.

LIQUIDITY AND CAPITAL RESOURCES

Cash flow

Net cash flows from operating activities

Net cash flows from operating activities amounted to $871 million in the first six months of 2024, compared to $410 million in the prior year period. The current year period includes increased collections associated with higher sales, lower taxes paid due to timing of payments and lower transformation payments following completion of the transformation program in the fourth quarter of 2023, partially offset by associate short-term incentive payments, which generally occur in the first quarter and were higher than in the prior year period, and increased payments for operating expenses. The prior period included a cash outflow for settlement of legal proceedings with Johnson & Johnson Surgical Vision, Inc. ("JJSVI"). Both periods were impacted by changes in net working capital.

Changes in net working capital in the current year were mainly driven by the net change in other operating liabilities and increases in trade receivables and inventories, partially offset by an increase in trade payables. The net change in other operating liabilities was primarily driven by the timing of annual associate short-term incentive payments. The increase in trade receivables was primarily driven by new receivables from higher sales outpacing collections. The increase in inventories was primarily to meet expected upcoming demand. The increase in trade payables was primarily driven by the timing of payments.

Changes in net working capital in the prior year period were mainly driven by increases in inventories and trade receivables and the net change in other operating liabilities and other operating assets. The increase in inventories was primarily to meet expected upcoming demand. The increase in trade receivables was primarily driven by new receivables from higher sales outpacing collections. The net change in other operating liabilities was primarily driven by the timing of annual associate short-term incentive payments. The net change in other operating assets was primarily driven by increases in the current portion of long-term receivables from customers, prepaid expenses and other receivables. Refer to Note 7 of the Condensed Consolidated Interim Financial Statements for additional details regarding changes within net working capital in the current and prior year periods.

Net cash flows used in investing activities

Net cash flows used in investing activities amounted to $351 million in the first six months of 2024, compared to $568 million in the prior year period. Cash outflows in the current year period primarily include capital expenditures, payments for financial assets measured at fair value through other comprehensive income ("FVOCI") and purchases of software and other intangible assets.

Cash outflows in the prior year period primarily included capital expenditures, payments for financial assets and purchases of intangible assets. Payments for financial assets primarily included a long-term note receivable related to new financing arrangements with Lifecore Biomedical, Inc. and certain of its affiliates (collectively, "Lifecore") in the second quarter of 2023 and long-term financial investments measured at FVOCI. Purchases of intangible assets primarily included intellectual property licenses.

Net cash flows used in financing activities

Net cash flows used in financing activities amounted to $237 million in the first six months of 2024, compared to $166 million in the prior year period. Cash outflows in the current year period primarily include dividends paid to shareholders of Alcon Inc., lease payments, withholding taxes paid upon net settlements of equity-based compensation and net payments related to certain local debt facilities.

Cash outflows in the prior year period primarily included dividends paid to shareholders of Alcon Inc., withholding taxes paid upon net settlements of equity-based compensation and lease payments, partially offset by net proceeds from local debt facilities.

Free cash flow (non-IFRS measure)

Free cash flow amounted to $667 million in the first six months of 2024, compared to $189 million in the prior year period, primarily due to increased cash flows from operating activities.

For additional information regarding free cash flow, which is a non-IFRS measure, see the explanation of non-IFRS measures and reconciliation tables in the 'Supplementary Information' section.

Balance sheet

Assets

Total non-current assets were $23.7 billion as of June 30, 2024, a decrease of $236 million when compared to $24.0 billion as of December 31, 2023. Intangible assets other than goodwill decreased $300 million due to recurring amortization, partially offset by additions of software and other intangible assets. Financial assets increased $91 million primarily due to purchases of long-term financial investments measured at FVOCI.

Total current assets were $6.0 billion as of June 30, 2024, an increase of $340 million when compared to $5.6 billion as of December 31, 2023. Cash and cash equivalents increased $278 million due to the net impact of operating, investing and financing activities as described in the preceding section. Our cash and cash equivalents are maintained at a number of financial institutions. To mitigate the risk of uninsured balances, we select financial institutions based on their credit ratings and financial strength, and we perform ongoing evaluations of these institutions to limit our concentration risk exposure. Trade receivables increased $59 million primarily driven by higher sales outpacing collections, partially offset by foreign currency translation effects.

Liabilities

Total non-current liabilities were $6.4 billion as of June 30, 2024, a decrease of $155 million when compared to $6.6 billion as of December 31, 2023. Financial debts decreased $126 million primarily due to the movement of local debt facility balances to current financial debts and foreign currency translation effects.

Total current liabilities were $2.3 billion as of June 30, 2024, a decrease of $58 million when compared to $2.4 billion as of December 31, 2023. Provisions and other current liabilities decreased $262 million primarily due to the timing of annual associate short-term incentive payments and payments related to the transformation program. Current financial debts increased $74 million primarily due to the movement of local debt facility balances from non-current financial debts, partially offset by net payments of certain local debt facilities. Current income tax liabilities increased $73 million primarily driven by the timing of payments and increased profitability. Trade payables increased $57 million primarily due to the timing of payments.

Equity

Equity was $20.9 billion as of June 30, 2024, an increase of $317 million when compared to $20.6 billion as of December 31, 2023.

Net (debt)/liquidity (non-IFRS measure)

Net debt of $3.3 billion as of June 30, 2024 decreased $339 million compared to $3.6 billion as of December 31, 2023. Alcon's liquidity amounted to $1.4 billion as of June 30, 2024, compared to $1.1 billion as of December 31, 2023. Total financial debt amounted to $4.7 billion as of June 30, 2024, in line with December 31, 2023.

The average maturity of financial debts outstanding as of June 30, 2024 is 10.3 years, and 97% of Alcon's financial debt is at fixed interest rates. We believe that we have adequate liquidity to meet our needs.

The $1.32 billion revolving credit facility remained undrawn as of June 30, 2024 and August 20, 2024.

For additional information regarding net (debt)/liquidity, which is a non-IFRS measure, see the explanation of non-IFRS measures and reconciliation tables in the 'Supplementary Information' section.

Additional Considerations

Foreign currencies

We use the US Dollar as our reporting currency and are therefore also exposed to foreign currency exchange movements and costs to enter hedging agreements, primarily in Euros, Japanese Yen, Chinese Renminbi, Canadian Dollars, Singaporean Dollars, Swiss Francs, Russian Rubles and emerging market currencies. The foreign currency exposure on the balance sheet is hedged with limited exception, but the impact of ongoing macroeconomic conditions is currently unknown and could have a material adverse effect on our results of operations, cash flows or financial condition.

NOTES TO CONDENSED CONSOLIDATED INTERIM FINANCIAL STATEMENTS OF ALCON INC. (unaudited)

1. Selected accounting policies

Basis of preparation

These Condensed Consolidated Interim Financial Statements for Alcon Inc. ("the Company") and the subsidiaries it controls (collectively, "Alcon") have been prepared in accordance with International Accounting Standard 34, Interim Financial Reporting, as issued by the International Accounting Standards Board ("IASB") and with the accounting policies as described in Note 2 to the December 31, 2023 Consolidated Financial Statements in the Company’s 2023 Form 20-F ("Form 20-F").

These Condensed Consolidated Interim Financial Statements do not include all of the information required for a complete set of International Financial Reporting Standards ("IFRS") financial statements. The financial information consolidates the Company and the subsidiaries it controls, and includes selected notes to explain events and transactions that are significant to an understanding of the changes in Alcon's financial position and performance since the prior annual Consolidated Financial Statements. Therefore, the Condensed Consolidated Interim Financial Statements should be read in conjunction with the annual Consolidated Financial Statements for the year ended December 31, 2023, which have been prepared in accordance with IFRS as issued by the IASB ("IFRS Accounting Standards") and can be found in the Form 20-F.

The accompanying Condensed Consolidated Interim Financial Statements present our historical financial position, results of operations, comprehensive income and cash flows in accordance with IFRS Accounting Standards. Alcon's principal accounting policies are set out in Note 2 to the Consolidated Financial Statements in the Form 20-F.

Use of estimates and assumptions

The preparation of Condensed Consolidated Interim Financial Statements requires management to make certain estimates and assumptions, either at the balance sheet date or during the period, that affect the reported amounts of assets and liabilities as well as revenues and expenses. Because of the inherent uncertainties, actual outcomes and results may differ from management's assumptions and estimates.

Impairment of goodwill, Alcon brand name and definite lived intangible assets

As discussed in Note 2 to the Consolidated Financial Statements in the Form 20-F, Goodwill, the Alcon brand name and acquired in-process research & development ("IPR&D") projects are reviewed for impairment at least annually and these, as well as all other investments in intangible assets, are reviewed for impairment whenever events or changes in circumstance indicate that the asset's balance sheet or reportable segment carrying amount may not be recoverable. Goodwill and other intangible assets represent a significant amount of total assets on the Consolidated Balance Sheet. Impairment testing may lead to potentially significant impairment charges in the future, which could have a materially adverse impact on Alcon's results of operations and financial condition.

Impact of adopting Amendments to International Accounting Standards 1

Effective January 1, 2024, Alcon adopted Amendments to International Accounting Standards 1 ("IAS 1"), Presentation of Financial Statements, which clarified the criteria used in determining the classification on the balance sheet of a liability as non-current where an entity has the right to postpone settlement of the liability for at least twelve months after the reporting date. Upon adoption of the amendment, current financial debts of $82 million for which Alcon has a right to roll over for at least twelve months after the December 31, 2023 balance sheet date were retrospectively reclassified to non-current financial debts.

New standards, interpretations and amendments not yet adopted

In April 2024, the IASB issued IFRS 18, Presentation and Disclosure in Financial Statements, which will replace IAS 1, Presentation of Financial Statements and accompanies limited amendments to other standards which will be effective upon the adoption of the new standard. IFRS 18 will be retroactively effective for our annual reporting periods beginning on January 1, 2027, with early adoption permitted. The standard is expected to improve comparability and transparency of financial statements by requiring defined subtotals in the Consolidated Income Statement, requiring disclosure of management-defined performance measures and adding new principles for aggregation and disaggregation of information. Alcon is currently evaluating the impact of this standard on its Consolidated Financial Statements.

Other than previously described, as of June 30, 2024 there are no IFRS Accounting Standards, interpretations or amendments not yet effective that would be expected to have a material impact on Alcon upon adoption.

2. Segmentation of key figures

The segment information disclosed in these Condensed Consolidated Interim Financial Statements reflects historical results consistent with the identifiable reportable segments of Alcon and financial information that the Chief Operating Decision Maker ("CODM") reviews to evaluate segmental performance and allocate resources among the segments. The CODM is the Executive Committee of Alcon.

The businesses of Alcon are divided operationally on a worldwide basis into two identified reportable segments, Surgical and Vision Care. Alcon's reportable segments are the same as its operating segments as Alcon does not aggregate any operating segments in arriving at its reportable segments. As indicated below, certain income and expenses are not allocated to segments.

Reportable segments are presented in a manner consistent with the internal reporting to the CODM. The reportable segments are managed separately due to their distinct needs and activities for research, development, manufacturing, distribution and commercial execution.

The Executive Committee of Alcon is responsible for allocating resources and assessing the performance of the reportable segments.

In Surgical, Alcon researches, develops, manufactures, distributes and sells ophthalmic products for cataract surgery, vitreoretinal surgery, refractive laser surgery and glaucoma surgery. The surgical portfolio also includes implantables, consumables and surgical equipment required for these procedures and supports the end-to-end procedure needs of the ophthalmic surgeon.

In Vision Care, Alcon researches, develops, manufactures, distributes and sells daily disposable, reusable, and color-enhancing contact lenses and a comprehensive portfolio of ocular health products, including products for dry eye, glaucoma, contact lens care and ocular allergies, as well as ocular vitamins and redness relievers.

Alcon also provides services, training, education and technical support for both the Surgical and Vision Care businesses.

The basis of preparation and the selected accounting policies mentioned in Note 1 are used in the reporting of segment results.

The Executive Committee of Alcon evaluates segmental performance and allocates resources among the segments primarily based on net sales and segment contribution.

Net identifiable assets are not assigned to the segments in the internal reporting to the CODM, and are not considered in evaluating the performance of the business segments by the Executive Committee of Alcon.

Segment contribution excludes amortization and impairment charges for acquired product rights or other intangibles, general and administrative expenses for corporate activities, transformation costs, fair value adjustments to contingent consideration liabilities, past service costs primarily for post-employment benefit plan amendments, acquisition and integration related costs, certain acquisition related items and certain other income and expense items.

General & administration (corporate) includes the costs of the Alcon corporate headquarters, including all related corporate function costs.

Other income and expense items excluded from segment contribution include fair value adjustments of financial assets in the form of options to acquire a company carried at fair value through profit and loss ("FVPL"), net gains and losses on fund investments and equity securities valued at FVPL, restructuring costs, legal provisions and settlements and other income and expense items not attributed to a specific segment.

3. Dividends and earnings per share

Dividends

On February 27, 2024, the Company's Board of Directors (the "Board") proposed a dividend of CHF 0.24 per share, which was subsequently approved by the shareholders at the Annual General Meeting on May 8, 2024 and paid in May 2024 for an amount of $130 million.

On February 27, 2023, the Board proposed a dividend of CHF 0.21 per share, which was subsequently approved by the shareholders at the Annual General Meeting on May 5, 2023 and paid in May 2023 for an amount of $116 million.

Earnings per share

As of June 30, 2024, there were 494.5 million outstanding common shares, after the delivery of 1.2 million net shares vesting under the equity incentive programs during the six months ended June 30, 2024.

Basic earnings per share is computed by dividing net income for the period by the weighted average number of common shares outstanding during the period. For the three and six months ended June 30, 2024, the weighted average number of shares outstanding was 494.5 million and 494.1 million, respectively. For the three and six months ended June 30, 2023, the weighted average number of shares outstanding was 493.2 million and 492.8 million, respectively.

The only potentially dilutive securities are the outstanding unvested equity-based awards, as described in Note 8. Except when the effect would be anti-dilutive, the calculation of diluted earnings per common share includes the weighted average net impact of unvested equity-based awards. For the three and six months ended June 30, 2024, the weighted average diluted number of shares outstanding was 497.0 million and 496.7 million, respectively, which includes the potential conversion of 2.5 million and 2.6 million unvested equity-based awards, respectively. For the three and six months ended June 30, 2023, the weighted average diluted number of shares outstanding was 495.7 million and 495.9 million, respectively, which includes the potential conversion of 2.5 million and 3.1 million unvested equity-based awards, respectively.

4. Intangible assets other than goodwill

Intangible asset impairment charges

Impairment charges during the three and six months ended June 30, 2024 amounted to $9 million recognized in Research & development in the Condensed Consolidated Income Statement due to the full impairment of an acquired IPR&D cash generating unit in the Surgical reportable segment due to discontinuation of the project. There were no impairment charges during the three or six months ended June 30, 2023.

5. Non-current and current financial debts

The below table summarizes non-current and current Financial debts outstanding as of June 30, 2024 and December 31, 2023.

Interest expense recognized for Financial debts, excluding lease liabilities, was $43 million and $83 million for the three and six months ended June 30, 2024, respectively, and $40 million and $81 million for the three and six months ended June 30, 2023, respectively.

Revolving credit facility

The $1.32 billion Revolving Credit Facility remained undrawn as of June 30, 2024.

6. Financial instruments

Fair value by hierarchy

As required by IFRS, financial assets and liabilities recorded at fair value in the Condensed Consolidated Interim Financial Statements are categorized based upon the level of judgment associated with the inputs used to measure their fair value. There are three hierarchical levels, based on an increasing amount of judgment associated with the inputs to derive fair value for these financial assets and liabilities, which are as follows:

Financial assets and liabilities carried at Level 1 fair value hierarchy are listed in active markets.

Financial assets and liabilities carried at Level 2 fair value hierarchy are valued using corroborated market data.

Level 1 financial assets include money market funds and deferred compensation assets. There were no financial liabilities carried at Level 1 fair value, and Level 2 financial assets and liabilities include derivative financial instruments.

Investments in money market funds are classified within Level 1 of the fair value hierarchy because they are valued using quoted market prices. The investments are classified as Cash & cash equivalents within the Condensed Consolidated Balance Sheet.

Deferred compensation investments for certain employee benefit plans are held in a rabbi trust and dedicated to pay the benefits under the associated plans but are not considered plan assets as the assets remain available to creditors of Alcon in certain events, including bankruptcy. Rabbi trust assets primarily consist of investments in mutual funds. These assets are classified within Level 1 of the fair value hierarchy because they are valued using quoted market prices.

Level 3 inputs are unobservable for the financial asset or liability. The financial assets and liabilities generally included in the Level 3 fair value hierarchy are equity securities and convertible notes receivable of private companies measured at fair value through other comprehensive income ("FVOCI"), fund investments, options to acquire private companies, and contingent consideration liabilities measured at FVPL.

The below tables summarize financial assets and liabilities measured at fair value on a recurring basis or at amortized cost or cost as of June 30, 2024 and December 31, 2023.

As of June 30, 2024, the probability of success for various development and commercial milestones ranges from 3% to 55% and the maximum remaining potential payments related to contingent consideration from business combinations is $395 million, plus other amounts calculated as a percentage of commercial sales in cases where there is not a specified maximum contractual payment amount. The estimation of probability typically depends on factors such as technical milestones or market performance and is adjusted for the probability of payment. If material, probable payments are appropriately discounted to reflect the impact of time.

Contingent consideration liabilities are reported in “Provisions & other non-current liabilities" based on the projected timing of settlement which is estimated to range from 2029 through 2035 for contingent consideration obligations as of June 30, 2024.

Long-term note receivable and other financial assets measured at amortized cost

As described in Note 17 to the Consolidated Financial Statements in the Form 20-F, on May 22, 2023, Alcon entered into financing arrangements with a long-term supplier, Lifecore Biomedical, Inc. and certain of its affiliates (collectively, “Lifecore”) resulting in financial assets which Alcon concluded were originated credit-impaired. The maximum exposure to credit risk is reflected in the carrying value of the assets, which amounted to $169 million as of June 30, 2024, including a non-current portion of $168 million in "Long-term note receivable and other financial assets measured at amortized cost" in Financial assets and a current portion of $1 million in "Other receivables, security deposits and current assets" in Other current assets. As of June 30, 2024, in accordance with the terms of the Pledge and Security agreement (“security agreement”), the credit risk exposure is fully mitigated by the collateral, with an estimated amount of approximately $320 million. The estimated amount of collateral decreased approximately 15% from December 31, 2023 based on updated forecasts reflecting recent market data and discounted cash flow analysis. There have been no significant changes in the quality of the collateral, the terms of the signed security agreement or the credit monitoring procedures described in Note 17 to the Consolidated Financial Statements in the Form 20-F. In addition, as of June 30, 2024, Alcon assessed there was no lifetime expected credit loss due to the value of the collateral under the security agreement.

Derivatives

The below table summarizes the net value of unsettled positions for currency derivatives contracts including swaps, forwards and options as of June 30, 2024 and December 31, 2023.

8. Equity-based compensation

As described in Note 23 to the Consolidated Financial Statements in the Form 20-F, Alcon has various equity incentive plans, under which Alcon may grant awards in the form of restricted stock units ("RSUs"), performance-based restricted stock units ("PSUs"), restricted stock awards ("RSAs"), or any other form of award at the discretion of the Board. Certain associates in select countries may also participate in share ownership savings plans.

The below table summarizes unvested share movements for all Alcon equity-based incentive plans for the six months ended June 30, 2024 and 2023:


	Six months ended June 30

Unvested at January 1	4.9	4.8
Granted	2.2	2.2
Vested	(1.7)	(1.8)
Forfeited	(0.1)	(0.1)
Unvested at June 30	5.3	5.1

9. Legal proceedings update

A number of Alcon companies are, and will likely continue to be, subject to various legal proceedings and investigations that arise from time to time, including proceedings regarding product liability, sales and marketing practices, commercial disputes, employment, wrongful discharge, antitrust, securities, health and safety, environmental, tax, international trade, privacy, intellectual property, including under the Hatch-Waxman Act, and anti-bribery matters such as those under the Foreign Corrupt Practices Act of 1977 ("FCPA"), as amended.

As a result, Alcon may become subject to substantial liabilities that may not be covered by insurance and could affect Alcon's business, financial position and reputation. While Alcon does not believe that any of these legal proceedings will have a material adverse effect on its financial position, litigation is inherently unpredictable and large judgments sometimes occur. As a consequence, Alcon may in the future incur judgments or enter into settlements of claims that could have a material adverse effect on its results of operations or cash flow. Note 18 to the Consolidated Financial Statements in the Form 20-F contains a summary of significant legal proceedings to which Alcon or any of its subsidiaries was a party as of the date of the Form 20-F. As of August 20, 2024, Alcon has fully and finally resolved the patent infringement claims it brought against the remaining defendants in the Hatch-Waxman litigation concerning Rocklatan and Rhopressa. There have been no other significant developments in the proceedings described in the Form 20-F nor any new significant proceedings commenced since the date of the Form 20-F.

Alcon believes that its total provisions for litigation and other legal matters are adequate based upon currently available information. However, given the inherent difficulties in estimating liabilities, additional liabilities and costs may be incurred beyond the amounts provided.

10. Related parties transactions

Investment in an associated company

As described in Note 24 to the Consolidated Financial Statements in the Form 20-F, Alcon holds approximately 8.5% voting interest of an associated company. The carrying amount of the investment in the associated company was $10 million as of June 30, 2024 and December 31, 2023. Long-term convertible notes due from the associated company included in Financial assets on the Condensed Consolidated Balance Sheet amounted to $11 million as of June 30, 2024 and December 31, 2023.

11. Subsequent events

On August 12, 2024, Alcon entered into a set of definitive agreements with Ocumension Therapeutics (Hong Kong) Limited (“Ocumension”), subject to customary closing conditions. Under the terms of the agreements, Alcon will divest its rights in China in favor of Ocumension to Bion Tears and Tears Naturale (reported in Vision Care segment) and procedural eye drops (reported in Surgical segment). Ocumension will also license the exclusive commercialization rights to Systane Ultra in China and development and commercialization rights to AR-15512 in China. In exchange, Alcon will receive up-front consideration in the form of approximately 16.7% of the ordinary shares of Ocumension. Alcon will also receive royalties and defined AR-15512 sales milestones. The transaction is expected to close in the fourth quarter of 2024.

These unaudited Condensed Consolidated Interim Financial Statements were authorized for issue by the Audit & Risk Committee on August 20, 2024.

SUPPLEMENTARY INFORMATION - DEFINITIONS AND RECONCILIATIONS OF NON-IFRS MEASURES

Non-IFRS measures as defined by the Company

Core results

Constant currencies

Constant currency calculations have the goal of eliminating two exchange rate effects so that an estimate can be made of underlying changes in the Consolidated Income Statement excluding:

•the impact of translating the income statements of consolidated entities from their non-US dollar functional currencies to the US dollar; and

•the impact of exchange rate movements on the major transactions of consolidated entities performed in currencies other than their functional currency.

EBITDA

Alcon defines earnings before interest, tax, depreciation and amortization ("EBITDA") as net income excluding income taxes, depreciation of property, plant and equipment (including any related impairment charges), depreciation of right-of-use assets, amortization of intangible assets (including any related impairment charges), interest expense and other financial income and expense. Alcon management primarily uses EBITDA together with net (debt)/liquidity to monitor leverage associated with financial debts.

Free cash flow

Net (debt)/liquidity

Alcon defines net (debt)/liquidity as current and non-current financial debt less cash and cash equivalents, current investments and derivative financial instruments. Net (debt)/liquidity is presented as additional information because management believes it is a useful supplemental indicator of Alcon's ability to pay dividends, to meet financial commitments and to invest in new strategic opportunities, including strengthening its balance sheet.

Growth rate and margin calculations

For ease of understanding, Alcon uses a sign convention for its growth rates such that a reduction in operating expenses or losses compared to the prior year is shown as a positive growth.

Gross margins, operating income margins and core operating income margins are calculated based upon net sales to third parties unless otherwise noted.

Selected accounting policies	Jun. 30, 2024
Corporate information and statement of IFRS compliance [abstract]
Selected accounting policies	Selected accounting policies Basis of preparation These Condensed Consolidated Interim Financial Statements for Alcon Inc. ("the Company") and the subsidiaries it controls (collectively, "Alcon") have been prepared in accordance with International Accounting Standard 34, Interim Financial Reporting, as issued by the International Accounting Standards Board ("IASB") and with the accounting policies as described in Note 2 to the December 31, 2023 Consolidated Financial Statements in the Company’s 2023 Form 20-F ("Form 20-F"). These Condensed Consolidated Interim Financial Statements do not include all of the information required for a complete set of International Financial Reporting Standards ("IFRS") financial statements. The financial information consolidates the Company and the subsidiaries it controls, and includes selected notes to explain events and transactions that are significant to an understanding of the changes in Alcon's financial position and performance since the prior annual Consolidated Financial Statements. Therefore, the Condensed Consolidated Interim Financial Statements should be read in conjunction with the annual Consolidated Financial Statements for the year ended December 31, 2023, which have been prepared in accordance with IFRS as issued by the IASB ("IFRS Accounting Standards") and can be found in the Form 20-F. The accompanying Condensed Consolidated Interim Financial Statements present our historical financial position, results of operations, comprehensive income and cash flows in accordance with IFRS Accounting Standards. Alcon's principal accounting policies are set out in Note 2 to the Consolidated Financial Statements in the Form 20-F. Use of estimates and assumptions The preparation of Condensed Consolidated Interim Financial Statements requires management to make certain estimates and assumptions, either at the balance sheet date or during the period, that affect the reported amounts of assets and liabilities as well as revenues and expenses. Because of the inherent uncertainties, actual outcomes and results may differ from management's assumptions and estimates. Impairment of goodwill, Alcon brand name and definite lived intangible assets As discussed in Note 2 to the Consolidated Financial Statements in the Form 20-F, Goodwill, the Alcon brand name and acquired in-process research & development ("IPR&D") projects are reviewed for impairment at least annually and these, as well as all other investments in intangible assets, are reviewed for impairment whenever events or changes in circumstance indicate that the asset's balance sheet or reportable segment carrying amount may not be recoverable. Goodwill and other intangible assets represent a significant amount of total assets on the Consolidated Balance Sheet. Impairment testing may lead to potentially significant impairment charges in the future, which could have a materially adverse impact on Alcon's results of operations and financial condition. Impact of adopting Amendments to International Accounting Standards 1 Effective January 1, 2024, Alcon adopted Amendments to International Accounting Standards 1 ("IAS 1"), Presentation of Financial Statements, which clarified the criteria used in determining the classification on the balance sheet of a liability as non-current where an entity has the right to postpone settlement of the liability for at least twelve months after the reporting date. Upon adoption of the amendment, current financial debts of $82 million for which Alcon has a right to roll over for at least twelve months after the December 31, 2023 balance sheet date were retrospectively reclassified to non-current financial debts. New standards, interpretations and amendments not yet adopted In April 2024, the IASB issued IFRS 18, Presentation and Disclosure in Financial Statements, which will replace IAS 1, Presentation of Financial Statements and accompanies limited amendments to other standards which will be effective upon the adoption of the new standard. IFRS 18 will be retroactively effective for our annual reporting periods beginning on January 1, 2027, with early adoption permitted. The standard is expected to improve comparability and transparency of financial statements by requiring defined subtotals in the Consolidated Income Statement, requiring disclosure of management-defined performance measures and adding new principles for aggregation and disaggregation of information. Alcon is currently evaluating the impact of this standard on its Consolidated Financial Statements. Other than previously described, as of June 30, 2024 there are no IFRS Accounting Standards, interpretations or amendments not yet effective that would be expected to have a material impact on Alcon upon adoption.

Earnings per share [abstract]
Dividends and earnings per share	Dividends and earnings per share Dividends On February 27, 2024, the Company's Board of Directors (the "Board") proposed a dividend of CHF 0.24 per share, which was subsequently approved by the shareholders at the Annual General Meeting on May 8, 2024 and paid in May 2024 for an amount of $130 million. On February 27, 2023, the Board proposed a dividend of CHF 0.21 per share, which was subsequently approved by the shareholders at the Annual General Meeting on May 5, 2023 and paid in May 2023 for an amount of $116 million. Earnings per share As of June 30, 2024, there were 494.5 million outstanding common shares, after the delivery of 1.2 million net shares vesting under the equity incentive programs during the six months ended June 30, 2024. Basic earnings per share is computed by dividing net income for the period by the weighted average number of common shares outstanding during the period. For the three and six months ended June 30, 2024, the weighted average number of shares outstanding was 494.5 million and 494.1 million, respectively. For the three and six months ended June 30, 2023, the weighted average number of shares outstanding was 493.2 million and 492.8 million, respectively. The only potentially dilutive securities are the outstanding unvested equity-based awards, as described in Note 8. Except when the effect would be anti-dilutive, the calculation of diluted earnings per common share includes the weighted average net impact of unvested equity-based awards. For the three and six months ended June 30, 2024, the weighted average diluted number of shares outstanding was 497.0 million and 496.7 million, respectively, which includes the potential conversion of 2.5 million and 2.6 million unvested equity-based awards, respectively. For the three and six months ended June 30, 2023, the weighted average diluted number of shares outstanding was 495.7 million and 495.9 million, respectively, which includes the potential conversion of 2.5 million and 3.1 million unvested equity-based awards, respectively.

Legal proceedings update	Jun. 30, 2024
Other Provisions, Contingent Liabilities And Contingent Assets [Abstract]
Legal proceedings update	Legal proceedings update A number of Alcon companies are, and will likely continue to be, subject to various legal proceedings and investigations that arise from time to time, including proceedings regarding product liability, sales and marketing practices, commercial disputes, employment, wrongful discharge, antitrust, securities, health and safety, environmental, tax, international trade, privacy, intellectual property, including under the Hatch-Waxman Act, and anti-bribery matters such as those under the Foreign Corrupt Practices Act of 1977 ("FCPA"), as amended. As a result, Alcon may become subject to substantial liabilities that may not be covered by insurance and could affect Alcon's business, financial position and reputation. While Alcon does not believe that any of these legal proceedings will have a material adverse effect on its financial position, litigation is inherently unpredictable and large judgments sometimes occur. As a consequence, Alcon may in the future incur judgments or enter into settlements of claims that could have a material adverse effect on its results of operations or cash flow. Note 18 to the Consolidated Financial Statements in the Form 20-F contains a summary of significant legal proceedings to which Alcon or any of its subsidiaries was a party as of the date of the Form 20-F. As of August 20, 2024, Alcon has fully and finally resolved the patent infringement claims it brought against the remaining defendants in the Hatch-Waxman litigation concerning Rocklatan and Rhopressa. There have been no other significant developments in the proceedings described in the Form 20-F nor any new significant proceedings commenced since the date of the Form 20-F. Alcon believes that its total provisions for litigation and other legal matters are adequate based upon currently available information. However, given the inherent difficulties in estimating liabilities, additional liabilities and costs may be incurred beyond the amounts provided.

Subsequent events	Jun. 30, 2024
Events After Reporting Period [Abstract]
Subsequent events	Subsequent events On August 12, 2024, Alcon entered into a set of definitive agreements with Ocumension Therapeutics (Hong Kong) Limited (“Ocumension”), subject to customary closing conditions. Under the terms of the agreements, Alcon will divest its rights in China in favor of Ocumension to Bion Tears and Tears Naturale (reported in Vision Care segment) and procedural eye drops (reported in Surgical segment). Ocumension will also license the exclusive commercialization rights to Systane Ultra in China and development and commercialization rights to AR-15512 in China. In exchange, Alcon will receive up-front consideration in the form of approximately 16.7% of the ordinary shares of Ocumension. Alcon will also receive royalties and defined AR-15512 sales milestones. The transaction is expected to close in the fourth quarter of 2024. These unaudited Condensed Consolidated Interim Financial Statements were authorized for issue by the Audit & Risk Committee on August 20, 2024.

Selected accounting policies (Policies)	Jun. 30, 2024
Corporate information and statement of IFRS compliance [abstract]
Statement of IFRS compliance	The accompanying Condensed Consolidated Interim Financial Statements present our historical financial position, results of operations, comprehensive income and cash flows in accordance with IFRS Accounting Standards.
Use of estimates and assumptions	Use of estimates and assumptions The preparation of Condensed Consolidated Interim Financial Statements requires management to make certain estimates and assumptions, either at the balance sheet date or during the period, that affect the reported amounts of assets and liabilities as well as revenues and expenses. Because of the inherent uncertainties, actual outcomes and results may differ from management's assumptions and estimates.
Impairment of goodwill, Alcon brand name and definite lived intangible assets	Impairment of goodwill, Alcon brand name and definite lived intangible assets As discussed in Note 2 to the Consolidated Financial Statements in the Form 20-F, Goodwill, the Alcon brand name and acquired in-process research & development ("IPR&D") projects are reviewed for impairment at least annually and these, as well as all other investments in intangible assets, are reviewed for impairment whenever events or changes in circumstance indicate that the asset's balance sheet or reportable segment carrying amount may not be recoverable. Goodwill and other intangible assets represent a significant amount of total assets on the Consolidated Balance Sheet. Impairment testing may lead to potentially significant impairment charges in the future, which could have a materially adverse impact on Alcon's results of operations and financial condition.
Impact of adopting Amendments to International Accounting Standards 1	Impact of adopting Amendments to International Accounting Standards 1 Effective January 1, 2024, Alcon adopted Amendments to International Accounting Standards 1 ("IAS 1"), Presentation of Financial Statements, which clarified the criteria used in determining the classification on the balance sheet of a liability as non-current where an entity has the right to postpone settlement of the liability for at least twelve months after the reporting date. Upon adoption of the amendment, current financial debts of $82 million for which Alcon has a right to roll over for at least twelve months after the December 31, 2023 balance sheet date were retrospectively reclassified to non-current financial debts.
New standards, interpretations and amendments not yet adopted	New standards, interpretations and amendments not yet adopted In April 2024, the IASB issued IFRS 18, Presentation and Disclosure in Financial Statements, which will replace IAS 1, Presentation of Financial Statements and accompanies limited amendments to other standards which will be effective upon the adoption of the new standard. IFRS 18 will be retroactively effective for our annual reporting periods beginning on January 1, 2027, with early adoption permitted. The standard is expected to improve comparability and transparency of financial statements by requiring defined subtotals in the Consolidated Income Statement, requiring disclosure of management-defined performance measures and adding new principles for aggregation and disaggregation of information. Alcon is currently evaluating the impact of this standard on its Consolidated Financial Statements. Other than previously described, as of June 30, 2024 there are no IFRS Accounting Standards, interpretations or amendments not yet effective that would be expected to have a material impact on Alcon upon adoption.
