Statement regarding use of non-GAAP financial measures
The company reports non-GAAP results for diluted earnings per share, gross margin, operating margin, and free cash flow, among others, in addition to, and not as a substitute for, or superior to, financial measures calculated in accordance with GAAP. The company's financial measures under GAAP include substantial charges such as amortization of acquired intangible assets, among others, that are listed in the reconciliations of GAAP and non-GAAP financial measures included in this press release. Management has excluded the effects of these items in non-GAAP measures to assist investors in analyzing and assessing past and future operating performance. Non-GAAP operating margin and diluted earnings per share are key components of the financial metrics utilized by the company's board of directors to measure, in part, management's performance and determine significant elements of management's compensation. The company encourages investors to carefully consider its results under GAAP, as well as its supplemental non-GAAP information and the reconciliation between these presentations, to more fully understand its business. Reconciliations between GAAP and non-GAAP results are presented in this release.

The company provides forward-looking guidance on a non-GAAP basis. The company is unable to provide a reconciliation of forward-looking non-GAAP financial measures to the most directly comparable GAAP reported financial measures because it is unable to predict with reasonable certainty the impact of items such as acquisition-related costs, fair value adjustments to contingent consideration, gains and losses from strategic investments, asset impairments, restructuring activities, and the ultimate outcome of pending litigation, among others, without unreasonable effort. These items are uncertain, inherently difficult to predict, depend on various factors, and could have a material impact on GAAP reported results for the guidance period. For the same reasons, the company is unable to address the significance of the unavailable information, which could be material to future results.

Use of forward-looking statements
This release contains forward-looking statements that involve risks and uncertainties. Among the important factors to which our business is subject that could cause actual results to differ materially from those in any forward-looking statements are: (i) changes in the rate of growth in the markets we serve; (ii) the volume, timing and mix of customer orders among our products and services; (iii) our ability to adjust our operating expenses to align with our revenue expectations; (iv) uncertainty regarding the impact of our inclusion on the "unreliable entities list" by regulatory authorities in China; (v) uncertainty regarding tariffs imposed or threatened by the U.S. government and its trading partners, related court proceedings or administrative actions (including potential additional refund or relief programs), and other possible tariffs or trade protection measures and our efforts to mitigate the impact of such tariffs; (vi) our ability to manufacture robust instrumentation and consumables; (vii) the success of products and services competitive with our own; (viii) challenges inherent in developing, manufacturing, and launching new products and services, including expanding or modifying manufacturing operations and reliance on third-party suppliers for critical components; (ix) the impact of recently launched or pre-announced products and services on existing products and services; (x) our ability to modify our business strategies to accomplish our desired operational goals; (xi) our ability to realize the anticipated benefits from prior or future actions to streamline and improve our R&D processes, reduce our operating expenses and maximize our revenue growth; (xii) our ability to further develop and commercialize our instruments, consumables, and products; (xiii) our ability to deploy new products, services, and applications, and to expand the markets for our technology platforms; (xiv) the risk of additional litigation or other liabilities arising against us in connection with previous acquisitions, including the GRAIL acquisition; (xv) our ability to obtain approval by third-party payors to reimburse patients for our products; (xvi) changes in the regulatory landscape and our ability to obtain regulatory clearance for our products from government agencies; (xvii) our ability to successfully partner with other companies and organizations to develop new products, expand markets, and grow our business; (xviii) uncertainty, or adverse economic and business conditions, including as a result of slowing or uncertain economic growth or armed conflict; (xix) the application of generally accepted accounting principles, which are highly complex and involve many subjective assumptions, estimates, and judgments; and (xx) legislative, regulatory and economic developments, together with other factors detailed in our filings with the Securities and Exchange Commission, including our most recent filings on Forms 10-K and 10-Q, or in information disclosed in public conference calls, the date and time of which are released beforehand. We undertake no obligation, and do not intend, to update these forward-looking statements, to review or confirm analysts' expectations, or to provide interim reports or updates on the progress of the current quarter.

(a)

Free cash flow, which is a non-GAAP financial measure, is calculated as net cash provided by operating activities reduced by purchases of property and equipment. Free cash flow is useful to management as it is one of the metrics used to evaluate our performance and to compare us with other companies in our industry. However, our calculation of free cash flow may not be comparable to similar measures used by other companies.

(a)	Revenue growth, excluding tariff refunds adjusts for the tariff refund to customers. Organic revenue growth adjusts for the impact from the tariff refund to customers, acquisitions and currency movements, which is calculated using comparative prior period foreign exchange rates to translate current period revenue, net of the effects of hedges. Rest of World (ROW) organic revenue growth also adjusts for the impact from our China region.
(b)	Non-GAAP gross profit, included within non-GAAP operating profit, is a key measure of the effectiveness and efficiency of manufacturing processes, product mix and the average selling prices of our products and services. Non-GAAP diluted earnings per share and non-GAAP operating profit exclude the effects of the pro forma adjustments as detailed above. Non-GAAP operating margin and diluted earnings per share are key components of the financial metrics utilized by the company's board of directors to measure, in part, management's performance and determine significant elements of management's compensation. Management has excluded the effects of these items in these measures to assist investors in analyzing and assessing past and future operating performance.
(c)	Reconciling amounts are recorded in cost of revenue.
(d)	Amounts for Q3 2026 and YTD 2026 consist primarily of:
	•	Amortization of intangible assets of $18 million and $53 million (cost of revenue)
	•	Amortization of inventory fair value step-up for SomaLogic of $2 million and $10 million (cost of revenue)
	•	Expenses for the SomaLogic and GRAIL acquisitions of $5 million and $26 million (operating expense)
	•	Net gains on contingent consideration liabilities of ($11) million and ($43) million (operating expense)
	Amounts for Q3 2025 and YTD 2025 consist primarily of:
	•	Amortization of intangible assets of $16 million and $50 million (cost of revenue)
	•	Expenses for the SomaLogic and GRAIL acquisitions of $4 million and $19 million (operating expense)
	•	Net losses (gains) on contingent consideration liabilities of $3 million and ($29) million (operating expense)
	•	Lease impairment of $4 million (operating expense)
(e)	Amounts for Q3 2026 and YTD 2026 consist primarily of implementation costs to upgrade our ERP system. Amounts for Q3 2025 consist primarily of implementation costs to upgrade our ERP system. Amounts for YTD 2025 consist primarily of employee severance costs from restructuring activities and costs related to the ERP upgrade.
(f)	Amounts consist of realized and unrealized gains and losses and impairments on our investments.
(g)	Amount consists of $3 million for costs related to board membership changes and $2 million for a legal accrual.
(h)	Amounts represent the aggregate of the difference between book and tax accounting related to stock-based compensation cost and the tax impact related to non-GAAP adjustments. Amounts for Q3 2025 and YTD 2025 also include a one-time $42 million valuation allowance adjustment recorded in Q3 2025 against deferred tax assets associated with certain U.S. foreign tax credits as a result of the U.S. tax legislation that was signed on July 4, 2025.
(i)	Amounts represent the impacts of IEEPA tariff refunds, consisting primarily of the $79 million benefit recognized as a reduction to cost of revenue in Q3 2026 and the related reduction to revenue of $37 million for the portion of tariff refunds that we expect to credit to customers.
