Key Highlights

  • Celestica Inc (TSX:CLS) fell 10.45% to CAD 383.50 in the October 22, 2026 midday session, which implies a previous close near CAD 428.30, simple arithmetic on the quoted decline.
  • Celestica Inc (TSX:CLS) is expected to report third quarter results after the close on October 26, 2026, with consensus of USD 2.94 adjusted earnings per share and USD 5.37 billion of revenue.
  • Company guidance for the third quarter is revenue of USD 5.25 billion to USD 5.55 billion and adjusted earnings per share of USD 2.88 to USD 3.08.
  • Celestica Inc (TSX:CLS) raised 2026 guidance on July 27, 2026 to revenue of USD 20.5 billion, adjusted earnings per share of USD 11.30, 8.4% adjusted operating margin and USD 600 million of free cash flow.

What Moved the Shares

No company release dated October 22, 2026 explains the 10.45% decline at Celestica Inc (TSX:CLS). The drop came in an AI and technology selloff: the Nasdaq Composite fell about 2.2% intraday, Lam Research fell about 9% after results, the iShares Semiconductor ETF about 4% and oil rose above USD 111 a barrel. Celestica builds networking and computing hardware for hyperscale cloud customers, so it trades with AI infrastructure sentiment. The stock is also heading into results, which can lead holders to cut positions. Results season for AI hardware adds to the pressure because investors are asking whether data center orders can keep growing at a rapid pace. A fall of 10.45% in one session is large for a company with a market value above USD 34 billion on its US-listed line.

Results Setup and Guidance

Celestica reported second quarter revenue of USD 4.70 billion, up 62%, with adjusted earnings per share of USD 2.54 against USD 1.39 a year earlier and an adjusted operating margin of 8.2%. Management expects 2026 revenue growth of about 65% and said 2027 growth should accelerate beyond that rate, with earnings growing faster than revenue. Results on October 26 come with a call on October 27 at 8:00 a.m. ET, and an investor day was listed alongside the report. The US-listed line opened at USD 303.51 on October 19, below its 50-day average of USD 332.79. Management also raised its 2026 free cash flow guidance to USD 600 million from USD 500 million and its adjusted operating margin guidance to 8.4% from 8.1%.

Risks and What to Watch

Hyperscale customers can change spending plans, supplier concentration is high, and a stock priced for rapid growth can fall on a small miss or cautious guidance. Insiders sold about 243,067 shares worth about USD 89.2 million over the past three months, including sales by the president and chief financial officer. The 12-month range of the US-listed line runs from USD 244.51 to USD 474.02. Nothing in this article is investment advice. A report that meets guidance but does not raise it can disappoint holders after a large run. Sales by insiders do not by themselves signal a view on the stock, since executives sell for many reasons, but they add to uncertainty. The stock is also well below its 200-day average of USD 350.92 on the US line.

Where Things Stand

The best-supported answer to the headline is an AI and technology selloff just ahead of earnings, since no company release dated October 22, 2026 was found. Celestica Inc (TSX:CLS) fell 10.45% to CAD 383.50. Third quarter results on October 26, 2026, the October 27 call, and the 2027 outlook given at the investor day are the next catalysts. The report will show whether AI demand has held up and whether the 2026 guidance is intact.
