|---|---|---|---|---|---|
| Security delivery timing and Middle East deferments in backlog | Mixed Mexico contract impacts drove headwind framing and guidance raise. | Mixed |
Improvements centered on backlog visibility, recurring services, and cash conversion; challenges were mainly timing-driven revenue volatility from Mexico and Middle East delays.
Management described record backlog and strong book-to-bill through Q1–Q4, culminating in approximately $1.9 billion year-end backlog to support multi-period visibility.
Across the year, management pointed to service revenue growth and recurrences from installed base, including SaaS-based and integration offerings that they expected to carry higher margins.
Management moved from SIP integration expectations to Shield participation, then to record RF revenues and the highest-ever RF engagement level, reinforcing a multi-year defense RF growth story.
Revenue trajectory showed early growth volatility around Mexico comps, then record backlog and cash momentum, with Q4 including Middle East delivery deferrals that reduced reported revenue timing.
Mix-driven margins, strong cash conversion at year end
Early FY2026 emphasized diversified operating momentum and raised guidance, then shifted to booking timing and margin normalization as Mexico and shutdown effects surfaced. In Q4, Middle East delivery deferrals lowered reported revenue but reinforced the backlog and cash conversion narrative heading into fiscal 2027.
Management framed Q1 as strong organic demand with record backlog and highlighted service growth, while Mexico and government shutdown timing were treated as headwinds embedded in raised full-year guidance.
Read earnings transcriptRevenue and EPS records came with Security booking softness attributed to shutdown-driven order delays and international timing. Management kept revenue guidance steady and pointed to a stronger second-half margin expansion opportunity.
FY2026 guidance was raised early and maintained later; Q4 explained revenue shortfall as planned delivery timing, with EPS/cash framed as strong despite phasing.
$1.825B to $1.867B; $10.20 to $10.48
Revenue $1.79B; EPS $8.95
Q1 raised revenue and non-GAAP EPS guidance, but full-year results ended below guidance due to delivery timing effects management attributed later in Q4.
$10.30 to $10.55
Revenue $1.79B; EPS $8.95
Management raised non-GAAP EPS guidance while keeping revenue guidance steady, yet the year closed with revenue timing-driven shortfalls explained by Q4.

Government programs & bookings timing
Across the year, management treated government shutdown and Middle East-related delays as scheduling issues. In Q1 and Q2, they highlighted expectations for later fiscal-year funding and orders; by Q4 they described deferred deliveries and emphasized awards remain in backlog for later conversion.
Defense RF execution
RF became a consistent investor focus, evolving from Q1 growth momentum and SaaS-based CertScan integration expectations into Q2 participation in Shield IDIQ and facility expansion. In Q3 and Q4, management discussed higher RF customer engagement and quantified RF revenues for Q3, while continuing to frame Golden Dome follow-on as multi-year.
Manufacturing demand & mix
Opto’s narrative moved toward recurring strength and resilience: management pointed to broad-based end-market demand and rising orders as OEMs diversify away from China. Q2 and Q3 emphasized book-to-bill and capacity readiness; Q4 tied profitability expansion to scale and mix, while forecasting continued underlying trends into fiscal 2027.

While collections varied quarter-to-quarter, management repeatedly tied free cash flow to DSO improvement and large Mexico receivable payments, culminating in record Q4 operating cash flow.
In Q3 management discussed delays tied to Middle East logistics and security protocols, and by Q4 they stated planned security deliveries pushed beyond June 30 due to those conditions.
Management raised guidance while highlighting a large Mexico headwind, and later described margin recovery opportunities in Q4 as Mexico YoY comparisons normalized.
Q2 and Q3 both referenced procurement and booking delays tied to government shutdowns, and management characterized the impact as timing rather than underlying demand change.
Healthcare performance was described as challenging in Q2 and adversely impacted by U.S. order timing in Q3, with improvement only later in Q4 driven by operational efforts.
