Lumentum Holdings (LITE) Earnings: Q1 Fiscal 2027 Results and Next Report Date

The quarter ended September 26, 2026 and Lumentum published the results on November 2, 2026. Revenue and diluted EPS are shown against Q1 fiscal 2026, the same quarter a year earlier, which takes seasonal swings out of the comparison. Lumentum reports EPS two ways: GAAP, under the accounting rules every US filer follows, and non-GAAP, which leaves out items the company considers outside its operating results. The release reconciles the two, and when they diverge, the reconciliation says why.

• Lumentum operates in one reportable segment. Components and Systems are the product types it uses to break out revenue.
• Lumentum's fiscal year ends on the Saturday closest to June 30. Fiscal 2027, ending July 3, 2027, is a 53-week year, with the extra week in the third quarter.
• The Q4 fiscal 2026 GAAP loss of $84.65 per share in the history table came from a $7,756.6 million loss on debt extinguishment when Lumentum exchanged convertible notes for stock.

How Lumentum splits revenue in its own release, under its own labels, for Q1 fiscal 2027 against Q1 fiscal 2026. Indented lines are parts of the line above them.

• Lumentum's Components revenue was $754 million in Q1 fiscal 2027, up 99% from $379 million in Q1 fiscal 2026, 60% of total revenue.
• Lumentum's Systems revenue was $508 million in Q1 fiscal 2027, up 229% from $155 million in Q1 fiscal 2026, 40% of total revenue.

Segment lines are the figures writers cite most often, because they show where the growth in a quarter came from. Companies redraw their segments from time to time and restate the prior year to match, so a year-ago figure here can differ from the one printed a year ago. When that has happened, the note above says so.

Lumentum's next report is scheduled for February 2, 2027. This page will show Q1 fiscal 2027 until those results are out and have been checked against the release.

Each quarter keeps its own page with the figures as reported, so a link to one stays pointed at the same numbers after the next report.

• Q1 fiscal 2027 (this page), reported Nov 2, 2026

Lumentum reported Q1 fiscal 2027 net revenue of $1,262.6 million, up 136.5% from $533.8 million a year earlier and 25.5% from $1,006.3 million in the prior quarter. Components brought in $754.2 million, 59.7% of the total, and Systems $508.4 million, up 228.8% year over year. (Lumentum Q1 FY27 release, Nov 2, 2026)

Lumentum operates as one reportable segment and splits revenue into Components and Systems. A Components product is an individual building block of a larger solution, such as semiconductor laser chips, laser sub-assemblies and line subsystems. Lumentum's products serve cloud, AI/ML, telecommunications, consumer and industrial applications. Its fiscal 2027 runs 53 weeks to July 3, 2027, with the extra week added to the third quarter. (Lumentum Form 10-Q, Q1 FY27, Nov 3, 2026; Lumentum Form 10-K, fiscal 2026, Aug 17, 2026)

According to the 10-Q, the ramp of laser chip and laser assembly shipments made up 66% of Components growth, for intra-data center, data center interconnect and long-haul uses. Systems growth came mainly from cloud transceivers, which rose more than 266% on volume, and optical circuit switch shipments contributed more than $108.0 million of revenue. (Lumentum Form 10-Q, Q1 FY27, Nov 3, 2026)

Lumentum's revenue is concentrated. Two end customers accounted for 37% and 11% of net revenue in the quarter, against 22% and 21% a year earlier. By shipping location, the United States took $297.4 million (23.6%), Mexico $230.8 million, Thailand $227.5 million, Hong Kong $187.1 million and China $162.0 million. (Lumentum Form 10-Q, Q1 FY27, Nov 3, 2026)

Lumentum's GAAP diluted EPS was $3.54 in Q1 fiscal 2027 and non-GAAP EPS $4.57, against $0.05 and $1.10 a year earlier. The biggest exclusion is stock-based compensation and related payroll taxes of $146.7 million, which included $89.4 million from modifying equity awards tied to an executive retirement announced in the quarter. Amortization of acquired intangibles added $32.8 million. (Lumentum Q1 FY27 release, Nov 2, 2026)

Lumentum's GAAP gross margin was 51.0% and its non-GAAP gross margin 53.2%, against 34.0% and 39.4% a year earlier. GAAP operating margin rose to 28.5% from 1.3%. The GAAP tax provision was $10.0 million, while the non-GAAP figure uses a fiscal 2027 rate of 16.5%. (Lumentum Q1 FY27 release, Nov 2, 2026)

Diluted shares rose to 101.7 million from 78.3 million, after Lumentum issued common stock in exchange for convertible notes and issued Series A Convertible Preferred Stock in March 2026. Those note exchanges produced a $7,756.6 million loss on debt extinguishment in fiscal 2026, which is why Q4 fiscal 2026 showed a GAAP loss of $84.65 per share. (Lumentum Q1 FY27 release, Nov 2, 2026; Lumentum Form 10-Q, Q1 FY27, Nov 3, 2026)

Diluted EPS divides net income by the weighted average number of shares outstanding in the quarter, plus the shares that options and other equity awards could add. Buybacks shrink that count and lift EPS for the same profit; share issuance and stock awards enlarge it.

Lumentum gives a one-quarter outlook in each release. For Q2 fiscal 2027 it expects net revenue of $1.575 billion to $1.625 billion, non-GAAP operating margin of 45.0% to 46.0% and non-GAAP diluted EPS of $5.90 to $6.20. It does not reconcile the outlook to GAAP, saying that cannot be done without unreasonable effort. (Lumentum Q1 FY27 release, Nov 2, 2026)

Lumentum's CEO said the company expects about $350 million of sequential revenue growth in Q2 and an operating margin above 45 percent. He also said Lumentum secured a second major NPO/CPO win backed by purchase commitments exceeding $5 billion. (Lumentum Q1 FY27 release, Nov 2, 2026)

A consensus figure is the average of the models published by the analysts who cover Lumentum, collected by a data provider and revised up to the day of the report. A quarter that lands above it says how expectations were set as much as how the business did, and the share price on the day also reflects the guidance and the lines no consensus covers.

The consensus figures on this page are Yahoo Finance's, as pulled on the date shown. Each comes with the number of analysts behind it; the smaller that number, the more one revised estimate can move the average.

The figures below are the ones Lumentum's own release and filings put weight on for Q1 fiscal 2027, with the latest reported value for each.

What the quarter means for a holding is a separate question from what it reported. The case for and against owning LITE is on is LITE a buy or a sell?, what analysts expect next is on the LITE forecast, and what the company does is on the Lumentum Holdings (LITE) stock page.

Every number on this page can be traced to a document Lumentum published. Checking one takes a couple of minutes, and it is worth doing before you quote a figure anywhere.

• The results release is the document linked in the source line above. Companies publish it on their investor relations site at the moment results go out, and it carries the headline tables: revenue, operating income, net income and EPS for the quarter and the year-ago quarter.
• The same release is filed with the SEC as Exhibit 99.1 to a Form 8-K under Item 2.02, usually on the day of the report. The SEC copy does not change after the fact, which makes it the safer thing to link when you cite a number.
• The quarterly report (Form 10-Q) follows within a few weeks and carries the full financial statements, the segment note and management's discussion of what changed. The fourth quarter is covered by the annual report (Form 10-K) instead.
• Restated comparisons are flagged in the notes on this page. When a company redraws its segments or changes how it adjusts EPS, it restates the year-ago column, so the year-ago figure in a new release can differ from the one printed a year ago. This page always uses the comparison in the newer release, because that is the like-for-like one.
