OSI Systems' Record Backlog Masks Middle East Revenue Delay as DHS Awards and LA28 Deal Point to FY28 Upside
Despite a ~$50M delivery pushout from Middle East conflict, OSIS books record Q4 cash flow and $1.9B backlog, guides conservative FY27 with growth weighted to the second half and beyond.

The Middle East Overhang
OSI Systems reported a fiscal 2026 fourth quarter that simultaneously showcased the company's underlying strength and exposed the friction of operating in a conflict zone. While total revenues of $484 million fell 4% year-over-year and missed guidance, the miss was almost entirely due to the timing of ~$50 million of planned security deliveries that slipped beyond the fiscal year end because of conflict-related delays and site access constraints in the Middle East. CFO Alan Edrick was emphatic on the call:
These expected revenues are deferred not orders lost. They remain firmly in our backlog and are expected to be delivered on a later schedule.
That confidence is backed by numbers. The company exited fiscal 2026 with a record Record backlog of approximately $1.9 billion, a 4% year-over-year increase in full-year revenues to $1.79 billion, and record non-GAAP EPS of $10.35 (up 11%). More striking, fourth-quarter operating cash flow hit a record $182 million, and free cash flow for the year was $276 million, enabling a $123.6 million share repurchase during the quarter. The stock, however, has been in a steep drawdown — down 29.5% over the last 90 days and roughly 33% off its April 2026 peak — as investors weigh the Middle East disruption against the company's otherwise solid operational performance.
New Wins and a Structural Shift
Beyond the timing issue, the quarter was marked by several substantive awards that underscore a longer-term growth narrative. Management highlighted two new sole-awardee IDIQ contracts from the Department of Homeland Security's CBP: one with a ceiling of approximately $200 million for relocatable Rapiscan passenger vehicle inspection systems, and a second of roughly $85 million for van-mounted mobile X-ray systems. "We have already received delivery orders under both these IDIQs, including a task order valued at about $21 million," noted CEO Ajay Mehra. These awards extend the funded pipeline from the "big, beautiful bill" and reinforce a theme that has dominated the last few quarters: Golden dome and the broader RF/homeland defense opportunity. The RF business, which posted record quarterly revenue of ~$38 million in the prior quarter, continues to see "the highest level of customer engagement... we have seen for this product line," per the call, with the $235 million undefinitized contract action for over-the-horizon radar systems already 80% booked into backlog.
At the same time, the company is making deliberate moves to expand its recurring revenue base. Service revenues grew 13% to $441 million for the full year, and management expects "strong double digit growth in service revenues" in fiscal 2027. This aligns with a structural margin story that has been building for years. As Edrick put it in the prior quarter's call: “That recurring revenue is high quality revenue at higher margins than our product revenues typically.” — Alan I. Edrick, Executive Vice President, Chief Financial Officer · 2025-08-21 The mix shift toward service is now complemented by a dedicated push into major event security, exemplified by the recently announced LA28 partnership that positions Rapiscan as the official physical screening provider for the 2028 Olympics and the company's growing list of marquee event wins (FIFA World Cup, Paris Olympics, Milan Winter Games).
A Conservative Guide That Points to FY28
For fiscal 2027, management guided revenue of $1.875–1.93 billion (5–8.1% growth) and non-GAAP EPS of $11.13–11.49 (7.5–11% growth). That is modestly below what the underlying trajectory might suggest, and management was explicit about the conservatism. "We are being a little bit modest and conservative," CFO Alan Edrick said on the call, citing incremental investments in innovation and infrastructure. The guidance includes only a portion of the CBP IDIQ deliveries in fiscal 2027 and assumes a later delivery schedule in the Middle East. CEO Ajay Mehra added, "We expect to see some revenue contribution from these awards later in fiscal 27 but significant contributions are expected in fiscal 28 and beyond as well." This is a clear signal that the company is managing expectations for a back-half-weighted year, with the real inflection point arriving in FY28.
The conservative posture stands in contrast to the optimism expressed in prior quarters. In the May 2026 call, Edrick highlighted the international growth engine: “We are seeing growth in a bunch of different areas. First off, geographically, we are seeing most of the growth internationally.” — Alan Edrick, Executive Vice President and CFO · 2026-05-04 Now, the Middle East conflict is explicitly the drag, replacing the earlier DHS shutdown theme that dominated fiscal 2025. The keyword trajectory reflects this pivot — "government shutdown" has faded from the top ranks over the past year, while "Middle East" related terms and "delivery order" have risen sharply.
The fundamental picture remains resilient. Over the long term, operating margin has expanded from roughly 7% in fiscal 2017 to a trailing 11.7% (though down 0.9pp year-over-year due to mix and the deferrals). Operating margin is on a structural upward path, supported by the service mix. On the valuation side, the stock now trades at ~2.4x price-to-revenue, in line with its historical median but well below the peak of 3.7x seen in 2017, despite the company's stronger cash generation and backlog position.
The market's reaction to the print was muted — the stock has already priced in the uncertainty. But the combination of a record backlog, a visible path to FY28 revenue acceleration from DHS and Golden Dome opportunities, and a service-led margin story makes this a name where the risk may be skewed to the upside if the Middle East normalization proceeds as management anticipates. As Mehra summarized: "the current level of customer engagement across our RF portfolio are the highest we have seen for this product line." That is the kind of statement that, if the conflict resolves, could re-rate the shares meaningfully.
