Most recent quarter (Q1 2026). Celestica reported Q1 2026 results on April 27, 2026 via 8-K and 10-Q. Revenue was $4,047.0M versus $2,648.6M in Q1 2025 — a 52.8% year-over-year increase. Net earnings were $212.3M versus $86.2M in Q1 2025, a 146% increase. Diluted EPS was $1.83 versus $0.74. The result reflects the continued ramp of networking switch programs with hyperscaler customers in the CCS segment. An earnings call was held April 28, 2026. (10-Q Q1 2026, filed 2026-04-27.)

Full-year FY2025 narrative. Revenue reached $12,390.9M, up 28.5% from $9,646.0M in FY2024. The CCS segment drove the growth: CCS revenue rose 42% to $9.19B, with the Communications end market (networking switches) up 81%, and HPS (Hardware Platform Solutions — Celestica's ODM business) representing 41% of total company revenue and up 81% YoY. The Enterprise end market within CCS fell 19% due to a technology transition in one AI/ML compute program with a hyperscaler customer. The ATS segment grew only 1% to $3.20B. Gross profit rose 45% to $1,494.1M, and operating margin expanded 220 basis points to 8.4% from 6.2% in FY2024. Net earnings nearly doubled to $832.5M from $428.0M. (10-K FY2025, filed 2026-02-27.)

Capital allocation and balance sheet. The company held $595.6M cash at December 31, 2025 (up from $423.3M at December 31, 2024) and carried $723.7M in term loan borrowings. Operating cash flow was $659.5M in FY2025, up 39% from $473.9M. Capex was $201.2M in FY2025 (1.6% of revenue), but management guided $1 billion (~6% of revenue) for 2026, a step-change reflecting the hyperscaler capacity build-out. The company repurchased 1.3M shares for $150.7M in FY2025 and 3.2M shares for $152.0M in FY2024. (10-K FY2025, filed 2026-02-27.)

Open questions

  1. Hyperscaler concentration risk: HPS revenue grew 81% in FY2025 and constituted 41% of total company revenue. The company explicitly discloses dependence on "a small number of customers for a substantial portion of our revenue." The Enterprise end market fell 19% due to a program transition with one hyperscaler customer — demonstrating that a single customer decision can move the needle meaningfully. What is the revenue share of Celestica's top 1–3 customers in the CCS segment? (Not disclosed in summary data; requires reading customer concentration disclosures in the full 10-K.) (10-K FY2025, filed 2026-02-27.)

  2. $1B capex build-out execution risk: Management guided approximately $1B in capex for 2026, compared to $201.2M in FY2025. New facilities are under development in the U.S., Thailand, Mexico, and Japan. Risk factors in the 10-K explicitly flag potential delays in utilities (power, grid interconnection), construction, and permitting. If customer demand fails to materialize at the anticipated pace, this infrastructure could be underutilized. What specific milestones and timeline checkpoints has management communicated to investors for these expansions? (10-K FY2025, filed 2026-02-27.)

  3. Tariff exposure: The 10-K devotes material disclosure to U.S. tariff policy impacts on both Celestica's non-U.S. manufacturing sites and its ability to pass tariff-related costs through to customers. Celestica manufactures in Thailand, Malaysia, Mexico, and other locations subject to potential U.S. import tariffs. Management's guidance at year-end assumed no material changes to tariff regimes from February 27, 2026. Given subsequent U.S. tariff announcements in Q1 2026, this assumption may no longer hold. What is Celestica's exposure under current tariff schedules, and how much cost passthrough has management negotiated? Monitor 8-K filings and Q1 2026 earnings call. (10-K FY2025, filed 2026-02-27.)

  4. Working capital requirements: Accounts receivable grew from approximately $2,069.0M at December 31, 2024 to $3,167.4M at March 31, 2026 (a 53% increase), and inventories grew from $1,760.6M to $2,672.9M over the same period. The company uses accounts receivable sales programs and supplier financing to manage working capital. The Q1 2026 10-Q shows A/R rose $529.3M and inventories rose $484.9M sequentially in one quarter. At current revenue growth rates, working capital demands could require additional credit facility draw or constrain free cash flow. (10-Q Q1 2026, filed 2026-04-27.)

  5. Enterprise end market recovery: The 19% decline in the Enterprise segment (AI/ML compute programs) in FY2025 was attributed to a technology transition at one hyperscaler customer. Management guided volume growth in 2026 in AI/ML compute programs. Has the technology transition concluded? What volume and margin characteristics does the new program carry versus its predecessor? (10-K FY2025, filed 2026-02-27.)
