- **[CATALYST] Power Electronics And Connectors Product or Capex Inflection** (NEGATIVE, Risk: HIGH): Execution risk is stable; capital spending for 2025 is estimated at 1.5% to 2.0% of revenue, focusing on capacity expansions in Thailand, Malaysia, and the U.S. to support AI/ML programs. (1 stable, 2 intensifying, 1 high-severity)
  > We continue to anticipate capital spending for 2026 to be approximately $1 billion, and expect to fund these expenditures from cash generated from operations.
- **[CATALYST] Power Electronics And Connectors Fed Rate Cycle** (NEUTRAL, Risk: MODERATE): The risk is intensifying as unhedged (variable rate) debt increased to $452.5 million at June 30, 2025, up from $411.2 million at year-end 2024. (1 intensifying, 1 easing, 2 stable)
  > At March 31, 2026, the interest rate risk related to $369.3 of borrowings under the Credit Facility was unhedged
- **[METRIC] Power Electronics And Connectors Balance Sheet Resilience** (NEUTRAL, Risk: MODERATE): The company relies on its ability to sell its IOUs (Accounts Receivable) to banks to maintain daily cash flow; if banks stop buying these, liquidity could tighten. [BALANCE_SHEET]
  > During Q1 2026, we sold an aggregate of $314 million under our A/R sales program and customer SFPs
- **[METRIC] Power Electronics And Connectors Free Cash Flow** (NEGATIVE, Risk: HIGH): Working capital pressure is intensifying; accounts receivable and inventory balances increased in 1H 2025, leading to a $66.5 million cash drain from working capital changes. (4 intensifying)

### Scenario Analysis

- The surge in hyperscaler capex for AI/ML compute and networking (first-order) has fundamentally re-rated Celestica's revenue growth, particularly through its proprietary HPS networking switches. This demand has forced a second-order expansion of the company's balance sheet and global manufacturing footprint to secure supply chains and manage extreme customer concentration. Ultimately, this shifts Celestica into a third-order position where its ability to convert massive infrastructure demand into durable cash flow depends on navigating external grid and power constraints that are outside of its direct control. (POSITIVE)
  > We may also experience delays or challenges related to utility, power availability, grid interconnection, supply chain constraints, and other infrastructure or regulatory requirements. Any of these factors could delay the realization of anticipated capacity.
- Initial trade frictions and export controls on AI technology act as a first-order headwind, forcing Celestica to manage higher inventory buffers and pass-through tariff costs to customers. However, this pressure has catalyzed a second-order strategic shift where Celestica is localizing manufacturing in the U.S. and Mexico to support hyperscaler demand. This localization transforms the company into a strategic partner for the U.S. AI ecosystem, leading to a third-order structural shift where Celestica captures higher-margin revenue from firms prioritizing supply chain control over low-cost offshore sourcing. (POSITIVE)
  > Due to global economic conditions, including the impact of ongoing trade conflicts, tariffs, and geopolitical conflicts, there has been and we expect there will continue to be uncertainty in the global economy. Management has made estimates and assumptions based on information available as of the da
- A shift toward lower Fed rates directly reduces Celestica's interest burden on its SOFR-linked Term Loans and Total Return Swaps, while simultaneously lowering the cost of capital for its primary growth engine: AI data center customers. This creates a second-order surge in demand for Celestica's Connectivity & Cloud Solutions (CCS) segment as hyperscalers accelerate infrastructure deployments. Ultimately, this leads to a third-order structural shift where Celestica re-rates as a high-growth AI infrastructure enabler rather than a cyclical contract manufacturer, benefiting from valuation expansion as long-duration growth multiples rise. (POSITIVE)
  > A one-percentage point increase in relevant interest rates would increase interest expense, based on outstanding borrowings under the Credit Facility at March 31, 2026, by $3.7 million annually, including the impact of our interest rate swap agreements, and by $7.2 million annually, without accounti
