Canada’s Smart Technologies (SMT) could debut today on Nasdaq under the stock ticker SMT after a successful IPO pricing Wednesday. And some say it could be one of the world‘s largest IPO offerings of 2010. Smart Technologies makes interactive whiteboards for education and business.

The offer, of 35 millions shares, should start off at $16 to $18 and could raise $635 million with an over allotment raising that to $730 million.

Smart Technologies expects to use part of the in proceeds from the sale to repay debt.

Smart posted a profit of $142 million for the year ended March 31 on revenue of $648 million. That contrasts with a loss of $107 million on revenue of $468 million the year before.

There is at least one naysayer on Smart. Fabrice Taylor wrote in the Toronto Globe & Mail early this month that the company has sold lots of stock to employees in the past 10 months at a weighted priced, adjusted for a reverse stock split, of about $2.40 a share.

“The prospectus has lots to say about why the shares are worth more today. You can read it for yourself. I’m somewhat skeptical,“ Taylor writes

Morgan Stanley, Deutsche Bank and RBC Dominion are leading the charge for Smart and Bank of America’s Merrill Lynch and Credit Suisse helping.
