Mandeep Chawla, CFO of Celestica Inc (CLS), executed 15 separate sales totaling 17,000 shares for $6,794,078.42 under a pre-arranged 10b5-1 trading plan adopted on 2026-03-13.

In his prior two sells at this ticker (2025-02-03 and 2025-01-31), the 30-day and 90-day post-transaction returns were negative, suggesting those sales preceded downward price movement; this current transaction's outcome will be tracked against that pattern as it unfolds.

Jason Phillips, President of Celestica, executed two separate sales totaling 120,000 shares for $36,892,200.00 on 2026-02-05 and 2026-02-06, with a blended average price of $307.44 against current price of $307.53.

His cross-ticker track record shows 2 prior sells with a 90d well-timed rate of 100.00%, and at Celestica specifically, his 2 prior sales (on 2025-02-03 and 2025-01-31) each showed negative 90-day returns of -23.1% and -30.0% respectively, both well-timed. The magnitude of this sale—liquidating the vast majority of his position—combined with his demonstrated pattern of selling before subsequent declines at this ticker, warrants investor attention given Celestica's elevated P/E of 49.36 and strong revenue growth of 21.2% year-over-year.

The current price of $297.45 represents a -15.6% decline from the 52-week high of $352.61 and is only $10 above the transaction price—placing this sale within his demonstrated pattern of selling ahead of subsequent drawdowns. This substantial reduction of insider stake merits investor attention given the established track record of well-timed exits at this specific ticker.

Etienvre Yann L, Chief Operations Officer at Celestica, executed two separate sales totaling 86,229 shares for $24,786,526.05, reducing his holdings from 86,229 shares to zero—a complete exit of his open-market position. The blended average transaction price of $287.45 sits $10.00 below current price of $297.45, representing a near-term opportunity cost. His cross-ticker track record shows 3 prior sells with a 90-day well-timed rate of 100.00% and average 90-day return of -26.6%, while at Celestica specifically, 2 of 2 prior measurable sales at the 90-day mark showed negative returns (-23.1% and -30.0%), suggesting a pattern of selling ahead of declines.

CHRO Wong Leila sells 29,950 shares for $8.6M at $287.00 avg; 68.3% stake reduction

Wong Leila, Chief Human Resources Officer at Celestica, executed 2 separate sales totaling 29,950 shares for $8,595,756.00, reducing her holdings by 68.3% from 43,842 to 13,892 shares. Her prior sales at CLS have shown a 90-day timing pattern of 2 of 2 well-timed at the 90-day mark, with the most recent December sell showing -8.6% at 30 days. Current trading activity occurs in an environment where the stock is -15.6% from its 52-week high of $352.61 and the company carries a P/E of 47.74 against $3.2B quarterly revenue. The magnitude of this stake reduction—coupled with the historical execution pattern at this ticker—warrants monitoring of subsequent price action relative to CLS fundamentals.

Chief Legal Officer Parker Douglas Michael sells all 2,724 shares of CLS for $781,733.52, exiting complete position

Parker Douglas Michael, Chief Legal Officer of Celestica, executed 2 separate sales on 2026-02-02 totaling 2,724 shares (2.7K shares) for $781,733.52 at a blended average price of $286.98, leaving him with 0 shares post-transaction. This represents a complete liquidation of his entire shareholding. The transaction occurred near the 52-week high—the stock is currently at $297.45, only -15.6% from its 52-week peak of $352.61—suggesting the insider divested at a favorable price level relative to recent history. The company's fundamentals remain robust, with annual revenue growth of +21.2% and a market cap of $34.2B, but the complete exit of an officer's position at elevated valuation warrants investor attention as a potential signal regarding the executive's near-term outlook or personal circumstances.

CHRO Wong Leila sells 3,160 CLS shares at $323.38; stock now -13.7% from 52-week high with 100% well-timed sell record at this ticker.

Wong Leila, Chief Human Resources Officer, sold 3,160 shares (18.5% of pre-transaction holdings) on 2025-12-01 at $323.38, reducing her stake from 17,052 to 13,892 shares. The stock currently trades at $304.29, down 13.7% from its 52-week high of $352.61 and down 11.7% in the prior 30 days, yet up 43.6% over 90 days. Wong's cross-ticker track record shows 2 prior sells with a 100% well-timed rate at the 90-day mark (average 90d return -23.0%), and at CLS specifically, both prior sells on 2025-02-03 were similarly well-timed with 90-day returns of -22.9% and -23.1%. The company reports strong fundamentals ($3.2B in latest quarterly revenue, $267.8M net income, 21.2% annual revenue growth) and trades at a P/E of 48.84 with a $35.0B market cap. The consistent pattern of Wong's sells preceding subsequent declines, combined with the current 13.7% drawdown from recent highs, suggests her transaction may align with her demonstrated timing skill, though broader macroeconomic or sector factors may be driving the recent price weakness.
