I. Item 1: Business Description

Core Services and Global Reach

Flex is an advanced contract‐manufacturing and design partner with 100 facilities in ~30 countries. Its two reportable segments cover:

1. Flex Agility Solutions (FAS) – data-center (“CEC”), consumer devices, lifestyle appliances & tools.
2. Flex Reliability Solutions (FRS) – industrial, automotive platforms, power electronics, health/medical devices.

With a 148,000-strong workforce and ~48 million sq ft of manufacturing space (43% in North America, 17% in China, 21% in EMEA, 19% in other regions), Flex delivers capabilities across the entire product lifecycle:

• Design & engineering (system architecture, industrial design, software integration) • Global supply-chain services (procurement, logistics, vendor-managed inventory) • Manufacturing (PCBA, systems assembly, miniaturization) • Post-production & fulfillment (warehousing, kitting, omni-channel) • Post-sale services (reverse logistics, refurbishment, recycling)

Strategic Evolution: “EMS + Products + Services”

Building on its core manufacturing strength, Flex is expanding its proprietary products portfolio and value-added services to deliver end-to-end solutions. Fiscal 2025 highlights:

• JetCool acquisition (2025) – micro-convective direct-to-chip liquid cooling for AI/data-center heat challenges. • Crown Technical Systems acquisition (2025) – critical power distribution, grid modernization and prefabricated switchgear. • Spin-off of Nextracker (Jan 2024) – solar tracker business distributed to shareholders, streamlining Flex’s focus.

Flex is now one of the few electronics manufacturing services (EMS) providers offering integrated racks, power & cooling hardware, and turnkey services from grid-to-chip for hyperscale and enterprise data centers.

II. Item 1A: Key Risk Factors

Flex faces a broad range of risks, including:

1. Cyclicality & order volatility – tech customers with short product lifecycles, rapid shifts in demand, order cancellations.
2. Customer concentration – top 10 customers ~44% of FY25 sales (none >10% individually), but loss of a major account has magnified impact.
3. Supply-chain disruptions – semiconductors, logistic constraints (e.g. geopolitical conflicts, Red Sea shipping attacks).
4. Tariffs & trade tensions – recent U.S. tariffs on China products increase cost of materials; passing on costs not guaranteed.
5. Competition & in-sourcing – global EMS peers, Taiwan ODMs, and select customers may bring production in-house.
6. Geopolitical & macro – Russia-Ukraine war, Israel-Hamas conflict, China-U.S. decoupling uncertainties.
7. Regulatory & compliance – data privacy, cybersecurity risks, RoHS/WEEE, sustainability reporting & evolving ESG standards.
8. Customer credit – tech downturns create receivables and inventory risk, impairments and weak credit exposure.

Flex discloses detailed mitigants, including geographic diversification, long-standing customer relationships, rigorous risk management, and sustainability investments, but macroeconomic shocks remain a key vulnerability.

III. Financial Results and Analysis

Consolidated Results (FY 2025 vs. FY 2024)

• Net sales: $25.8 billion (–2% YoY) – FAS sales up 1% (Cloud strength; +$1 billion buy-sell activity) – FRS sales down 6% (softer industrial renewables & auto demand) • Gross profit: $2.16 billion (+16% YoY); margin up 130bp to 8.4% – Mix, operational efficiencies, lower restructuring charges • Operating income: $1.17 billion (+37% YoY) at 4.5% margin • Net income (continuing ops): $838 million (–4% YoY); EPS $2.11 • Adjusted free cash flow: $1.08 billion vs. $0.82 billion – Cash from ops $1.51 billion (+14%); CapEx $0.44 billion • Balance sheet – Cash $2.29 billion; Net debt ~$1.5 billion – Liquidity includes $2.5 billion H/C revolver; no revolver borrowings

Outlook factors: FY26 guidance not yet released. Key drivers will be data-center spending on AI, consumer electronics cycles, industrial & automotive investment, and trade dynamics.

Segment Profits—FAS & FRS

Segment	FY25 Sales	% Change	FY25 Margin	FY24 Margin
FAS	$14.07 B	+1%	6.1%	4.8%
FRS	$11.74 B	–6%	5.8%	5.3%

FAS margin expansion of 130 bps was driven by cloud data-center racks & power products; Consumer Devices also rose 15%. FRS benefited from Crown’s high-margin critical power; weak renewables prices offset.

Cash Flow and Capital Deployment

• Operating cash flow $1,505 M (+14% YoY) from higher profits, working cap improvement.
• CapEx $438 M (1.7% of sales) on capacity & automation vs. $530 M prior year. • M&A and Acquisitions – $405 M cash for Crown, JetCool, Orangeburg plant. • Share buybacks – $1.3 billion repurchased in FY25 at avg $32.66/share; $1.0 billion remains authorized. • Debt – $3.7 billion outstanding, including 2032 Notes; $2.5 billion revolver undrawn.

Free cash flow strength allows the company to invest in new technologies, return capital, and strengthen its balance sheet.

VII. Conclusion & Score

Flex presents a balanced, evolving growth story: from a pure contract manufacturer to a full “EMS + Products + Services” provider, carving out proprietary power and cooling IP for AI-intensive data centers, while retaining diversified industrial, automotive and healthcare services. Its FY25 results demonstrate resiliency, margin improvement and robust cash flow in a choppy market.
