Scout Capital Management has upped its ownership stake in the Canadian restaurant chain to 5.5 per cent, according to documents filed Monday with the U.S. Securities and Exchange Commission.
The hedge fund had a 1.48 per cent stake in the coffee and doughnut chain at the end of March.
Scout says it has engaged in discussions with senior management at Tim Hortons about the chain's capital structure and expenditures, the timing and size of its share repurchases, management compensation metrics and technology investments.
The company said it expects these discussions to continue.
Meanwhile, Tim Hortons said it doesn't comment on meetings with individual investors.
"We are continuing to focus on our track record of creating shareholder value and welcome feedback from all of our shareholders," said spokesman Scott Bonikowsky in a statement.
The news comes after reports that U.S. hedge fund Highfields Capital Management pushed for changes at Tim Hortons at the end of April.
Highfields wanted Tim Hortons to borrow $3.4 billion to buy back more than a third of its stock, create a real estate trust for its real estate assets and spin off or sell its distribution business.
However, the restaurant chain said it wouldn't be spinning off its real estate holdings because doing so would not create significant value for the company.
Tim Hortons owns about 20 per cent of its more than 3,400 restaurant locations and kiosks, though most are leased. It also owns its corporate headquarters and distribution centres.
Meanwhile, Tim Hortons is preparing for incoming leader Marc Caira, a longtime senior executive at Nestle, who will officially take over from interim CEO Paul House on July 2.
Last month, Tim Hortons reported weaker first-quarter profits, with net income attributable to stockholders down 2.9 per cent to $86.2 million, from $88.8 million in the same 2012 period.
The company, which has faced an onslaught of competition from the likes of coffee chains like Starbucks and fast food restaurants like McDonald's, said that overall traffic at its locations was flat.
