NEWS RELEASE
CN Announces
New Normal Course Issuer Bid
for Share Repurchase and 3% Dividend Increase
MONTREAL, January 30, 2026 —
CN (TSX: CNR) (NYSE: CNI) announced today that its Board of Directors has approved a 3% increase in the 2026 dividend on the Company's
outstanding common shares as well as the repurchase of its shares under a new normal course issuer bid (Bid).
“These actions reflect CN’s strong
cash flow and our disciplined approach to managing capital. We are investing in the business, returning capital to shareholders and maintaining
a strong balance sheet to support long-term performance.”
| – | Ghislain Houle, Executive Vice-President and Chief Financial Officer, CN |
The Bid permits CN to purchase, for cancellation,
over a 12-month period up to 24 million common shares, representing 3.9% of the 613,523,348 common shares issued and outstanding of the
Company on January 22, 2026. On that date, 613,155,320 common shares not held by insiders were issued and outstanding.
The Bid will be conducted between February 4,
2026, and February 3, 2027, through a combination of discretionary transactions and automatic repurchase plans at market prices prevailing
at the time of purchase, through the facilities of the Toronto and New York stock exchanges, or alternative trading systems in Canada
and in the United States, if eligible, and will conform to their regulations. Purchases may also be conducted using derivative-based programs,
accelerated share repurchase transactions, or other methods of acquiring shares, subject to any required regulatory and stock exchange
approvals and on such terms and at such times as shall be permitted by applicable laws.
The decisions regarding the timing and size of
future purchases of common shares under the Bid are subject to management’s discretion and are based on a variety of factors, including
market conditions. The new Bid was approved by the Toronto Stock Exchange (TSX) on January 29, 2026. TSX rules permit CN to
purchase daily, through TSX facilities, a maximum of 395,423 common shares under the Bid.
CN believes that the repurchase of its shares
represents an appropriate and beneficial use of the Company's funds.
CN's current normal course issuer bid, announced
in January 2025 for the purchase of up to 20 million common shares, expires on February 3, 2026. As at the close of trading
on January 22, 2026, CN had repurchased 15,250,222 common shares at a weighted-average price of C$134.44 per share, excluding brokerage
fees, returning C$2,050 million to its shareholders. Purchases were made through the facilities of the TSX and alternative trading systems.
CN's Board of Directors also approved a first-quarter
2026 dividend on the Company's outstanding common shares. A quarterly dividend of ninety-one and a half cents (C$0.9150) per common share
will be paid on March 31, 2026, to shareholders of record at the close of business on March 10, 2026.
