Cameco (TSX: CCO; NYSE: CCJ) has won C$300 million ($220m) back from Canada’s taxman in a dispute lasting two decades, but it says the full figure should be more than three quarters of a billion Canadian dollars.

 

Canada’s largest uranium miner says it’s due to receive C$89 million in cash and C$211 million in letters of credit after reassessments by Canada Revenue Agency concerning tax filings for 2007 through 2013. However, the company says it is owed a further C$480 million in cash and credit because of court decisions on the same tax issues in different years.

“The clear and decisive court rulings already rendered in this dispute likewise apply to these amounts,” Cameco said in a statement on Mar. 27. “CRA should fully reverse the remining transfer pricing adjustments for these years, return the full amount of cash and security being held, and bring this matter to an end once and for all.”

 

The C$480 million, composed of C$206 million in cash and C$274 million in letters of credit held by the CRA, concerns sales of uranium by Swiss subsidiary Cameco Europe and ties up “a significant portion of our financial capacity,” Cameco said.

 

The Saskatoon-based company has appealed to Canada’s Tax Court to complete the refund for the 2007-13 tax filings, and it has also disputed CRA assessments for 2014-16, it said.

 

The tax battle centres on how CRA shifted Cameco Europe’s income back to Canada for the years 2003 to 2014 and applied tax rates, interest and penalties, and transfer pricing penalties from 2007 to 2011, Cameco said in February. The company won at the federal Tax Court and federal Appeals Court before the Supreme Court dismissed CRA’s case on the 2003, 2005 and 2006 tax year filings.

 

“Although not technically binding, there is nothing in the reasoning of the lower court decisions that should result in a different outcome for the 2007 through 2014 tax years, which were reassessed on the same basis,” Cameco said.

 

The company is benefiting from a resurgence in nuclear energy’s image to fight climate change and fewer uranium supplies in the market because of the war in Ukraine. After 2022 results showed a swing into profit, Cameco is preparing to complete the joint acquisition with Brookfield Renewable Partners (NYSE: BEP) of nuclear plant builder Westinghouse in a $7.9 billion deal.

 

Cameco’s Cigar Lake mine is at full production while the McArthur River and Key Lake operations are to hit full output next year. The company has signed a record number of contracts to sell about 80 million lb. of uranium, including a multi-year deal with Ukraine.

 

Shares in Cameco gained 1.2% to C$34.04 each on Tuesday afternoon in Toronto, within a 52-week range of C$25.55 and C$41.05, valuing the company at C$14.7 billion ($10.8bn).
