CN announces two-for-one stock split, 30 per cent increase in cash dividend.

MONTREAL -- CN announced today that its Board of Directors has approved a two-for-one stock split of the company's common shares outstanding. The Board has also approved a 30 per cent increase in CN's quarterly cash dividend.

The two-for-one stock split will take the form of a stock dividend. Shareholders will receive one additional common share of CN for each common share held. The stock dividend will be payable on Feb. 28, 2006, to shareholders of record at the close of business on Feb. 22, 2006.

In addition, a quarterly cash dividend of sixteen and one-quarter cents (C$0.1625) per common share post-split will be paid on March 31, 2006, to shareholders of record at the close of business on March 10, 2006.

E. Hunter Harrison, president and chief executive officer of CN, said: "I am very proud of CN's strong financial record since it became a publicly traded corporation in November 1995. The stock split and dividend we're announcing today reflect management's and the directors' continuing confidence in CN's ability to deliver solid earnings and cash flow in the future."

Including today's dividend announcement, CN - since the company's initial public offering of shares in 1995 - has increased its cash dividend annually 10 times by a total of almost 400 per cent. In addition, since 1995, CN has split its stock three times as its share price has increased tenfold.

The stock split will have no tax consequences in Canada or the United States, and will not dilute shareholders' equity.

CN's current share-repurchase program and all equity-based benefit plans will be adjusted to reflect the issuance of additional shares or options due to the declaration of the stock split. All share and per share data for future periods will also reflect the stock split.
