T5Additionally, the Company strengthened its balance sheet position, reducing its overall debt by $302 million during the fiscal fourth quarter and $1.4 billion during fiscal year 2026, exiting the fiscal year with total debt of $3.6 billion. As of the end of the fiscal year, cash and cash equivalents totaled $1.7 billion, and there were 227 million ordinary shares issued and outstanding.

Seagate has issued a Supplemental Financial Information document, which is available on Seagate’s Investor Relations website at investors.seagate.com.

Quarterly Cash Dividend

The Board of Directors of the Company (the “Board”) declared a quarterly cash dividend of $0.74 per share, which will be payable on October 7, 2026 to shareholders of record as of the close of business on September 24, 2026. The payment of any future quarterly dividends will be at the discretion of the Board and will be dependent upon Seagate’s financial position, results of operations, available cash, cash flow, capital requirements and other factors deemed relevant by the Board.

Business Outlook

The business outlook for the fiscal first quarter 2027 is based on our current assumptions and expectations; actual results may differ materially, as a result of, among other things, the important factors discussed in the Cautionary Note Regarding Forward-Looking Statements section of this release.

T6The Company is providing the following guidance for its fiscal first quarter 2027:

•G1Revenue of $4.1 billion, plus or minus $100 million

•G2Non-GAAP diluted EPS of $7.30, plus or minus $0.20

Our fiscal first quarter guidance includes:

•The estimated net dilutive impact from the Exchangeable Senior Notes due 2028; and

•T7Minimal expected impact from global tariff policies and/or the current conflict in the Middle East as of the date of this release.

Guidance regarding non-GAAP diluted EPS excludes known pre-tax charges related to estimated share-based compensation expenses of $0.26 per share.

We have not reconciled our non-GAAP diluted EPS guidance for fiscal first quarter 2027 to the most directly comparable GAAP measure, other than estimated share-based compensation expenses, because material items that may impact these measures are out of our control and/or cannot be reasonably predicted, including, but not limited to, net (gain) loss from debt transactions, strategic investment losses (gains) or impairment charges, income tax adjustments on these measures, and other charges or benefits that may arise. The amounts of these measures are not currently available but may be material to future results. A reconciliation of our historical non-GAAP financial measures to their nearest GAAP equivalent is contained in this release.

Use of non-GAAP financial information

The Company uses non-GAAP measures of gross profit, gross margin, operating expenses, income from operations, operating margin, net income, diluted EPS, free cash flow, EBITDA, adjusted EBITDA and last twelve months adjusted EBITDA, which are adjusted from results based on GAAP to exclude certain benefits, expenses, gains and losses. These non-GAAP financial measures are used by management to evaluate the business and provided to enhance the user’s overall understanding of the Company’s current financial performance and its prospects for the future. Specifically, the Company believes non-GAAP results provide useful information to investors as these non-GAAP results exclude certain benefits, expenses, gains and losses that the Company believes are not part of the Company's ongoing operations and not indicative of its core operating results.

These non-GAAP financial measures are some of the measurements management uses to assess the Company’s performance, allocate resources and plan for future periods. Reported non-GAAP results should only be considered as supplemental to results prepared in accordance with GAAP, and not considered as a substitute or replacement for, or superior to, GAAP results. These non-GAAP measures may differ from the non-GAAP measures reported by other companies in its industry.

_____________________________________

1 The Company recorded $16 million of restructuring charges in the three months ended June 27, 2025, of which $3 million was recorded to Cost of revenue and $13 million was recorded to Restructuring and other, net, within Operating expenses. During fiscal year 2025, the Company recorded $38 million of restructuring charges, of which $13 million was recorded to Cost of revenue and $25 million was recorded to Restructuring and other, net, within Operating expenses.

2 For the three and twelve months ended July 3, 2026, and the three and twelve months ended June 27, 2025, using the if-converted method, approximately 2 million, 6 million, 3 million and 3 million shares, respectively, are issuable upon conversion of our 2028 exchangeable senior notes. These dilutive effects are expected to be offset partially by the capped call transactions and are excluded from non-GAAP shares used in diluted net income per share calculation.

The Company’s Non-GAAP measures are adjusted for the following items:

Acquisition-related charges

Acquisition-related charges are primarily related to transaction and integration costs. These expenses are excluded in the non-GAAP measures due to the inconsistency in amount and frequency, and they are not normal operating expenses or indicative of the Company’s operating performance. Exclusion of these amounts provides a supplemental view of the Company’s operating performance to investors to enable them to evaluate the Company’s current operating performance compared to the past periods’ operating performance.

Amortization of acquired intangible assets

The Company records expense from amortization of intangible assets that were acquired in connection with its business combinations over their estimated useful lives. Such charges are inconsistent in size and are significantly impacted by the timing and magnitude of the Company’s acquisitions. Consequently, the Company excludes these amounts to provide a supplemental view to investors to evaluate the Company’s current operating performance compared to the past periods’ operating performance.

Legal settlement

From time to time, the Company incurs charges related to the settlement of litigation matters. These charges are inconsistent in amount and frequency and are excluded from the Company’s non-GAAP measures to provide a supplemental view to investors to evaluate the Company’s current operating performance compared to the past periods’ operating performance.

Net gain/loss from business divestiture

From time to time, the Company records net gains or losses from the sale of businesses. These net gains or losses are excluded in the non-GAAP measures because they are not indicative of the Company’s operating performance. The Company excludes these amounts to provide a supplemental view to investors to evaluate the Company’s current operating performance compared to the past periods’ operating performance.

Net gain/loss from debt transactions

From time to time, the Company incurs gains, losses and fees from the early redemption and repurchase of certain long-term debt instruments. The amount of these charges may be inconsistent in size and varies depending on the timing of the early redemption of debt. The Company does not believe these are part of its normal operating performance. Exclusion of these amounts provides a supplemental view of the Company’s operating performance to investors to enable them to evaluate the Company’s current operating performance compared to the past periods’ operating performance.

Purchase order cancellation fees

Purchase order cancellation fees are the costs incurred to cancel certain purchase commitments made with the Company’s suppliers for component and equipment purchases that will not be received due to change in forecasted demand. These charges and subsequent credits received are inconsistent in amount and frequency. The Company does not believe these are part of its normal operating expenses. Exclusion of these amounts provides a supplemental view to investors to evaluate the Company’s current operating performance compared to the past periods’ operating performance.

Restructuring and other, net

Restructuring and other, net are costs associated with restructuring plans that are primarily related to costs associated with reduction in the Company’s workforce, exiting certain facilities, inventory write down related to discontinued product lines and other related costs, as well as charges or gains from sale of properties. These costs or benefits do not reflect the Company’s normal or ongoing operating performance and consequently the Company excludes these expenses to provide a supplemental view to investors to evaluate the Company’s current operating performance compared to the past periods’ operating performance.

Share-based compensation

These expenses consist primarily of expenses for employee share-based compensation. Given the variety of equity awards used by companies, the varying methodologies for determining share-based compensation expense, the subjective assumptions involved in those determinations, and the volatility in valuations that can be driven by market conditions outside the Company’s control, the Company believes excluding share-based compensation expense enhances the ability of management and investors to understand and assess the underlying performance of its business over time and compare it against the Company’s peers, a majority of whom also exclude share-based compensation expense from their non-GAAP results.

Strategic investment gains, losses and impairment charges

From time to time, the Company incurs gains, losses or impairment charges from strategic investments that are measured and accounted at fair value, under the equity method of accounting, as available-for-sale debt securities or adjust for downward or upward adjustments to the carrying value under the measurement alternative if an impairment or observable price adjustment is recognized in the current period that are not considered normal operating expenses or gains. The resulting expense, gain or impairment loss is inconsistent in amount and frequency and the Company excludes these amounts to provide a supplemental view to investors to evaluate the Company’s current operating performance compared to the past periods’ operating performance.

Other charges

The other charges primarily include IT transformation costs. These charges are inconsistent in amount and frequency and are excluded to provide a supplemental view to investors to evaluate the Company’s current operating performance compared to past periods’ operating performance.

Income tax adjustments

Seagate utilizes a projected annual non-GAAP income tax rate to determine its non-GAAP income taxes. The annual non-GAAP tax rate is based on considerations such as its current tax structure, projected tax positions and impacts from key legislation implemented in various jurisdictions but excludes the tax effects of pre-tax non-GAAP adjustments and other significant non-recurring income tax items. The Company believes applying the non-GAAP tax rate provides consistency across the interim reporting periods and reduces the effects of items not directly related to its operating structure that can vary in size and frequency. The non-GAAP income tax rate could be subject to change for a variety of reasons, including significant changes in tax laws. The Company will re-evaluate periodically its non-GAAP tax rate and may adjust as appropriate. For fiscal year 2026, the Company uses a projected non-GAAP income tax rate of 15.5%.

Non-GAAP diluted share count adjustments

Using the if-converted method, diluted net income per share is calculated assuming that the excess value above the principal of the 2028 exchangeable notes were converted solely into shares of common stock at the beginning of the reporting period, unless the result would be anti-dilutive. Non-GAAP shares used in diluted net income per share calculation excluded certain dilutive shares, which are expected to be offset partially by the capped call transactions entered by the Company in conjunction with our 2028 exchangeable senior notes in order to reduce the potential dilution to the Company’s ordinary shares upon the conversion.

Free cash flow

Free cash flow is a non-GAAP measure defined as net cash provided by operating activities less acquisition of property, equipment and leasehold improvements. Free cash flow does not reflect non-cash items, net cash used or provided by financing activities and net cash used or provided by investing activities, other than acquisition of property, equipment and leasehold improvements. This non-GAAP financial measure is used by management to assess the Company’s sources of liquidity, capital structure and operating performance.

EBITDA, adjusted EBITDA and last twelve months (LTM) adjusted EBITDA

EBITDA is defined as net income before income tax expense, interest expense, interest income, depreciation and amortization. Adjusted EBITDA excludes certain expenses, gains and losses that the Company believes are not indicative of its core operating results. These adjustments primarily include impairment and other charges related to cost saving efforts, net loss (gain) from debt transactions, net loss (gain) from business divestiture, purchase order cancellation fees, restructuring and other, net, share-based compensation, strategic investment losses or impairment charges, other extraordinary charges such as factory underutilization charges. LTM adjusted EBITDA is defined as the total of last twelve months adjusted EBITDA. These non-GAAP financial measures are used by management to evaluate the Company’s debt portfolio and structure to comply with its financial debt covenants.
