**NEWS RELEASE**![lumentum_logoa26a.jpg](lumentum_logoa26a.jpg)

**<u>LUMENTUM ANNOUNCES SECOND QUARTER OF FISCAL YEAR 2026 FINANCIAL RESULTS</u>**

*• Net revenue of $665.5 million*

*• GAAP gross margin of 36.1%; Non-GAAP gross margin of 42.5%*

*• GAAP operating margin of 9.7%; Non-GAAP operating margin of 25.2%*

*• GAAP diluted net income per share of $0.89; Non-GAAP diluted net income per share of $1.67* 

**San Jose, Calif., February 3, 2026** – Lumentum Holdings Inc. ("Lumentum" or the "Company") today reported results for its fiscal second quarter ended December 27, 2025.

"Lumentum delivered a standout second quarter, with over 65 percent year-over-year revenue growth and non-GAAP operating margin expansion above 1,700 basis points," said President and CEO Michael Hurlston. "Revenue hit the high end of our guidance range, while profitability and EPS expanded well beyond prior guidance, demonstrating the leverage of our business model."

"Our forward guidance calls for over 85 percent year-over-year revenue growth, yet we are only at the starting line for two substantial opportunities: optical circuit switches (OCS) and co-packaged optics (CPO). In OCS, we are scaling rapidly to meet extraordinary customer demand that has already driven our backlog well beyond $400 million. In CPO, we received an incremental multi-hundred-million-dollar order, deliverable in first half calendar 2027. Our results continue to highlight the strength of our roadmaps for both optical components and systems, which make us mission-critical to the world's AI leaders."

***Fiscal Second Quarter Highlights:***

Net revenue for the second quarter of fiscal year 2026 was $665.5 million, with GAAP net income of $78.2 million, or $0.89 per diluted share. Net revenue for the first quarter of fiscal year 2026 was $533.8 million, with GAAP net income of $4.2 million, or $0.05 per diluted share. Net revenue for the second quarter of fiscal year 2025 was $402.2 million, with GAAP net loss of $60.9 million, or $0.88 per diluted share.

Non-GAAP net income for the second quarter of fiscal year 2026 was $143.9 million, or $1.67 per diluted share. Non-GAAP net income for the first quarter of fiscal year 2026 was $86.4 million, or $1.10 per diluted share. Non-GAAP net income for the second quarter of second year 2025 was $30.0 million, or $0.42 per diluted share.

The Company held $1,155.3 million in total cash, cash equivalents, and short-term investments at the end of the second quarter of fiscal year 2026, up $33.5 million from the end of the first quarter of fiscal year 2026.

The tables above provide comparisons of quarterly results to prior periods, including sequential quarterly and year-over-year changes. A reconciliation between GAAP and non-GAAP measures is contained in this release under the section titled "Use of Non-GAAP Financial Measures."

**Business Outlook** 

***Lumentum expects the following for the third quarter of fiscal year 2026:***

*• Net revenue in the range of $780 million to $830 million*

*• Non-GAAP operating margin of 30.0% to 31.0%* 

*• Non-GAAP diluted earnings per share of $2.15 to $2.35*

We have not provided reconciliations from GAAP to non-GAAP financial measures or the equivalent GAAP measure for non-GAAP financial measures in our outlook, as they cannot be provided without unreasonable effort. A large portion of non-GAAP adjustments, such as stock-based compensation, acquisition related costs (income), integration related costs, restructuring and related charges (reversals), non-GAAP income tax reconciling adjustments, and other costs and contingencies unrelated to current and future operations are by their nature highly volatile and we have low visibility as to the range that may be incurred in the future.

**Related Announcement and Conference Call**

Lumentum will host a conference call today, February 3, 2026, at 2:00 pm PT / 5:00 pm ET to discuss its second quarter of fiscal year 2026 results.

These forward-looking statements involve risks and uncertainties that could cause actual results to differ materially from those projected. Among the factors that could cause actual results to differ from those contemplated are: (a) uncertainty and volatility in the global markets, including uncertainty and volatility in the macroeconomic environment, volatility and uncertainty with respect to economic growth, inflationary pressures, changes in the political or economic environment, such as geopolitical conflicts, war, international trade regulation and restrictions (including tariffs, duties and export controls to be implemented by the U.S. and other countries), including for certain rare earth minerals, and the effect of such market disruptions on demand for our products, technology spending by our customers, our costs and expenses and our ability to obtain components for our products; (b) quarter-over-quarter product mix fluctuations, which can materially impact profitability measures due to the broad gross margin ranges across our portfolio; (c) decline of average selling prices across our businesses or increase in costs, either of which will also decrease our margins; (d) effects of seasonality; (e) our ability to increase our manufacturing capacity and our ability and the ability of our suppliers and contract manufacturers to meet production, quality, and delivery requirements for our forecasted demand; (f) changes in customer demand, including due to changes in inventory practices and end-customer demand, and potential order cancellations, reductions or delays and their effects; (g) our ability to attract and retain new customers, particularly in the cloud photonics and imaging and sensing markets; (h) the risk that our markets will not grow or develop as expected or that our strategies and ability to compete in those markets are not successful, (i) the risk that Lumentum's financing or operating strategies will not be successful; (j) risks related to our restructuring initiatives and changes to our operations; (k) failure to successfully integrate acquisitions into our business or that we will not achieve the expected benefits; (l) risks related to servicing our current and future debt and compliance with the covenants under our revolving credit facility. A detailed discussion of these and other risks and uncertainties that could cause actual results and events to differ materially from such forward-looking statements is included in the Company's Quarterly Report on Form 10-Q for the fiscal quarter ended September 27, 2025 filed with the Securities and Exchange Commission (the "SEC) and the Company's other filings with the SEC, including the Quarterly Report on Form 10-Q for the fiscal quarter ended December 27, 2025 to be filed with the SEC, available at www.sec.gov, under the "Risk Factors" section and elsewhere.

**Use of Non-GAAP Financial Measures**

In this press release, Lumentum provides investors with certain non-GAAP financial measures: gross profit, gross margin, research and development expense, selling, general and administrative expense, operating margin, income (loss) from operations, other income (expense), net, income before income taxes, provision for income taxes, net income (loss), shares used in per share calculation, and net income (loss) per share on a non-GAAP basis, as well as the non-GAAP measures of EBITDA and Adjusted EBITDA. Lumentum believes this non-GAAP financial information provides additional insight into the Company's on-going business operations and results, and has therefore chosen to provide this information to investors for a more consistent basis of comparison and to help them evaluate the results of the Company's on-going operations and enable more meaningful period to period comparisons. In addition, the Company believes that providing certain of these measures allows investors to better understand the Company's operating performance and, importantly, to evaluate the methodology and information used by management to monitor, manage, evaluate and measure the Company's business and results of operations. However, investors are cautioned that there are material limitations associated with the use of non-GAAP financial measures as an analytical tool. In particular, many of the adjustments to our GAAP financial measures reflect the exclusion of items that are recurring and will be reflected in our financial results for the foreseeable future. Moreover, the non-GAAP financial measures we present may be different from non-GAAP financial measures used by other companies or may not be comparable to similarly titled measurements reported by other companies, limiting their usefulness for comparison purposes. We do not consider non-GAAP financial measures to be a substitute for, or superior to, the information provided by GAAP financial measures, and the non-GAAP financial measures used in this press release should not be considered in isolation from measures of financial performance prepared in accordance with GAAP.

Our non-GAAP measures used in this press release exclude (i) stock-based compensation and related payroll taxes, (ii) acquisition related costs (income), (iii) integration related costs, (iv) amortization of acquired intangibles, (v) restructuring and related charges (reversals), (vi) foreign exchange (gains) losses, net, (vii) non-cash interest expense on convertible notes, (viii) intangible assets write-off, (ix) inducement expense on partial repurchase of 2026 Notes, (x) escrow settlement and related charges, (xi) non-GAAP income tax reconciling adjustments, and (xii) other charges or income related to non-recurring activities.

We utilize a long-term projected non-GAAP tax rate to compute our non-GAAP income tax provision. The long-term projected non-GAAP tax rate is based on a multi-year projection of our estimated annual GAAP income tax forecast, adjusted to account for the tax effect of non-GAAP pretax adjustments as well as the effects of significant non-recurring and period specific tax items. Our non-GAAP tax provision for fiscal year 2026 is 16.5%. The difference between our GAAP income tax provision and our non-GAAP income tax provision is presented as non-GAAP income tax reconciling adjustments.

A quantitative reconciliation between GAAP and non-GAAP financial data is included in the supplemental financial table attached to this press release.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;<sup>(1)</sup> Stock-based compensation and related payroll taxes for the three and six months ended December 27, 2025 includes $2.5 million and $6.6 million of payroll taxes on stock-based compensation, respectively.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;<sup>(2)</sup> Acquisition related costs (income), net for the three and six months ended December 27, 2025 represent $1.8 million of interest income from the Cloud Light escrow fund in other income, net, offset by the associated legal expenses incurred related to Cloud Light escrow settlement of $0.4 million and $1.7 million both in selling, general and administrative expenses for the three and six months ended December 27, 2025, respectively.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;<sup>(3)</sup> During the three months ended December 27, 2025, we recorded a net reversal to our restructuring and related charges of $0.4 million attributable to lower-than-estimated employee severance and wind-down charges. Restructuring and related charges for the six months ended December 27, 2025 primarily relate to reduction in force during the period in order to enhance operational efficiency and realign our investments toward the most critical initiatives.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;<sup>(4)</sup> During the three months ended December 27, 2025, we completed the settlement process with the sellers on the escrow agreement for the acquisition of Cloud Light. We believe the completion of this settlement represents a non-recurring activity as it relates directly to an acquisition. The settlement of $27.5 million, recorded in escrow settlement, for the three and six months ended December 27, 2025 represents the mutually agreed escrow settlement associated with indemnification obligations and working capital adjustments, including warranty adjustments, under the Cloud Light Merger agreement. Acquisition-related warranty provision relates to $9.8 million of warranty expense associated with Cloud Light's legacy products is recorded in cost of sales. As the measurement period for U.S. GAAP expired, these amounts were all included in our condensed consolidated results of operations on a GAAP basis as no further adjustments to the purchase consideration of Cloud Light can be made. Therefore, for non-GAAP reporting purposes, we have removed the net benefit of $17.7 million for the three and six months ended December 27, 2025.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;<sup>(5)</sup> Inducement expense on the partial repurchase of our 2026 Notes for the six months ended December 27, 2025 represents the excess of fair value of the total consideration over the fair value of securities issuable pursuant to the original conversion terms.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;<sup>(6)</sup> Other charges, net for the three and six months ended December 27, 2025 mainly includes an impairment charge of $7.5 million to write-down assets held for sale to fair value less cost to sell in selling, general and administrative expenses, and the remaining amount mostly relates to legal and professional fees primarily related to non-ordinary course legal matters in selling and general and administrative expenses.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;<sup>(7)</sup> The adjustment for the three and six months ended December 27, 2025 represents the impact of the capped call options. Our outstanding capped call options are anti-dilutive under GAAP as they are specifically designed to mitigate the dilutive impact of the 2032 Notes, such that no dilution will occur until the capped call price is exceeded. Therefore, we included the 1.7 million and 0.9 million shares anti-dilutive impact of the capped call from the calculation of non-GAAP diluted shares in the three and six months ended December 27, 2025 to provide investors with useful information in evaluating our performance on a per share basis.
