OSI Systems, Inc. (OSIS) Earnings: Q1 Fiscal 2027 Results and Next Report Date

The quarter ended September 30, 2026 and OSI Systems published the results on October 29, 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. OSI Systems 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.

• OSI Systems' fiscal year ends June 30, so Q1 fiscal 2027 is the three months ended September 30, 2026. OSI reports in thousands; figures here are in millions.
• The Optoelectronics & Manufacturing row includes sales to OSI's own Security and Healthcare divisions; the Corporate/Elimination row removes them, so the rows sum to total net revenues.

How OSI Systems 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.

• OSI Systems's Security revenue was $264 million in Q1 fiscal 2027, up 4% from $254 million in Q1 fiscal 2026, 65% of total revenue.
• OSI Systems's Optoelectronics & Manufacturing revenue was $120 million in Q1 fiscal 2027, up 9% from $109 million in Q1 fiscal 2026, 30% of total revenue.
• OSI Systems's Healthcare revenue was $35.1 million in Q1 fiscal 2027, down 14% from $40.7 million in Q1 fiscal 2026, 9% 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.

From the earnings release

In the release's outlook table the first range in each row is the previous guidance and the second the updated guidance.

In its Q1 fiscal 2027 release, OSI Systems said:

“The Company is reaffirming its fiscal 2027 revenue guidance and increasing its fiscal 2027 non-GAAP diluted earnings per share guidance, as set forth above.”

“Revenues $1.875 billion - $1.930 billion $1.875 billion - $1.930 billion”

“Non-GAAP Earnings Per Share $11.13 - $11.49 $11.28 - $11.64”

“The Company's fiscal 2027 diluted earnings per share guidance is provided on a non-GAAP basis only.”

This is the company's own guidance as of Oct 29, 2026, quoted as given. Walnut does not make forecasts of its own. Analyst estimates for the coming quarters are on the OSIS forecast page.

Revenue and diluted EPS for the last 5 quarters. Each date links to that quarter's release.

Total net revenues and GAAP diluted EPS, each as first reported in that quarter's release. OSI Systems' fiscal year ends June 30; its first fiscal quarter is usually its smallest.

OSI Systems's next report is expected around January 28, 2027, a date estimated from its reporting history that the company has not yet confirmed. 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 Oct 29, 2026

OSI Systems reports three segments: Security, Optoelectronics and Manufacturing, and Healthcare. In Q1 fiscal 2027 total net revenues were $403.5 million, up 4.9%. Security brought in $264.1 million, 65.5% of the total, Optoelectronics and Manufacturing $104.3 million from external customers (25.8%) and Healthcare $35.1 million (8.7%). (OSI Systems Form 10-Q, Q1 fiscal 2027, Oct 29, 2026; OSI Systems Q1 fiscal 2027 release, Oct 29, 2026)

OSI Systems' Security revenue rose 3.9%, from about $3.6 million more product revenue and $6.2 million more service revenue. OSI said RF systems and checkpoint screening grew while cargo and vehicle inspection revenue was lower, and that service growth came from a larger installed base and airport screening services. For fiscal 2026 the Security division's direct sales to the U.S. Government were approximately $207.3 million. (OSI Systems Form 10-Q, Q1 fiscal 2027, Oct 29, 2026; OSI Systems Form 10-K, fiscal 2026, Aug 21, 2026)

OSI Systems' Optoelectronics and Manufacturing external revenue rose 16.4% on about $5.5 million more optoelectronics product revenue and $9.2 million more contract manufacturing revenue. Healthcare revenue fell 13.8% because of lower patient monitoring revenues, principally in the U.S., which OSI attributed to the timing of customer orders. (OSI Systems Form 10-Q, Q1 fiscal 2027, Oct 29, 2026)

OSI Systems booked $583 million of orders in the quarter, a book-to-bill ratio of 1.4, and its backlog rose to a record $2.1 billion from $1.9 billion at June 30, 2026. By type, products were $289.8 million of revenue and services $113.6 million. Gross margin fell to 30.7% from 32.0% because of lower higher-margin Healthcare revenue, a less favorable Security mix and more lower-margin Optoelectronics and Manufacturing revenue. (OSI Systems Q1 fiscal 2027 release, Oct 29, 2026; OSI Systems Form 10-Q, Q1 fiscal 2027, Oct 29, 2026)

OSI Systems earned net income of $24.6 million, or $1.51 per diluted share, in Q1 fiscal 2027, up 28% from $1.18. Non-GAAP EPS was $1.66, up 17% from $1.42. Its non-GAAP figures exclude restructuring and other charges ($2.1 million, $0.13 per share), amortization of acquired intangible assets ($2.6 million, $0.16), the tax effect of those items and discrete tax items. (OSI Systems Q1 fiscal 2027 release, Oct 29, 2026)

OSI Systems' diluted weighted average shares fell to 16,252 thousand from 17,473 thousand. OSI repurchased 305,559 shares in the quarter, about $62 million of capital returned, and had 773,172 shares left under its authorization at September 30, 2026. Interest and other expense, net fell to $3.3 million from $7.4 million. (OSI Systems Q1 fiscal 2027 release, Oct 29, 2026)

OSI Systems' effective tax rate was 18.8%, against 19.9%, and included a net discrete tax benefit of $1.2 million related to equity-based compensation, which the non-GAAP figures remove ($0.07 per share). (OSI Systems Form 10-Q, Q1 fiscal 2027, Oct 29, 2026; OSI Systems Q1 fiscal 2027 release, Oct 29, 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.

OSI Systems gives a fiscal-year outlook in its release, for revenue and non-GAAP EPS only. With Q1 fiscal 2027 it reaffirmed revenue of $1.875 billion to $1.930 billion, 5.0% to 8.1% growth, and raised non-GAAP diluted EPS guidance to $11.28 to $11.64, from $11.13 to $11.49. It does not give GAAP EPS guidance or a reconciliation to it. (OSI Systems Q1 fiscal 2027 release, Oct 29, 2026)

OSI Systems said it expects the Security division's operating margin to improve over the rest of fiscal 2027 as its revenue mix stabilizes and service revenues increase, and it anticipates a return to growth in Healthcare this fiscal year. (OSI Systems Q1 fiscal 2027 release, Oct 29, 2026)

A consensus figure is the average of the models published by the analysts who cover OSI Systems, 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 OSI Systems'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 OSIS is on is OSIS a buy or a sell?, what analysts expect next is on the OSIS forecast, and what the company does is on the OSI Systems, Inc. (OSIS) stock page.

Every number on this page can be traced to a document OSI Systems 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.
