Bausch Health Companies Inc. slightly missed earnings estimates in the second quarter even as it nudged up its full-year forecast Tuesday on better results. Chief executive Joseph Papa said he expects Bausch — formerly known as Valeant Pharmaceuticals — will generate between US$8.4 billion and US$8.6 billion in revenue this year, about US$50 million more than its previous outlook. The company said its second-quarter net loss attributable to shareholders was $170 million, reduced from $872 million a year earlier.SNC-Lavalin Inc. (TSX:SNC). Down $1.45 or 8.1 per cent to $16.36. Shares of SNC-Lavalin Inc. plummeted to the lowest level in nearly 15 years Tuesday in reaction to its largest shareholder, the Caisse de depot et placement du Quebec, warning that the embattled engineering firm had to move to emergency mode to improve its project execution. The Montreal-based company’s shares fell to a low of $16.10 in early trading on the Toronto Stock Exchange. The Caisse booked a $700-million loss from its SNC investment during the first six months of the year and CEO Michael Sabia’s impatience was clearly evident.Hudson’s Bay Co. (TSX:HBC). Down two cents to $9.78. Investment firm Catalyst Capital Group Inc. says it has boosted the number of Hudson’s Bay Co. shares it’s seeking to buy in an effort to oppose a proposal to privatize the retailer. The firm says it is now seeking to buy up to 19.8 million shares at $10.11 each, up from 14.8 million shares, for a total bid value of $200 million. The offer, seeking about 10.75 per cent of outstanding shares, came after an insider group led by board chairman Richard Baker made a bid in June of $9.45 per share to take the retailer private. Catalyst says the Baker-led offer greatly undervalues the company, which owns the Saks Fifth Avenue, Hudson’s Bay, Lord &Taylor and Saks OFF 5th retail brands as well as significant real estate holdings.Aurora Cannabis Inc. (TSX:ACB). Up 66 cents or 7.9 per cent to $9.05.

(TSX:MRE). Down 26 cents or 2.5 per cent to $10.
