Masrani declined to comment when asked if TD was committed to reviewing financial terms or walking away from the deal.
First Horizon could not be immediately reached for comment.
Some shareholders have been urging TD to ditch the deal after the collapse of Silicon Valley Bank and Signature Bank in March triggered a crisis of confidence. TD has said the merger would make it the sixth-largest U.S. bank, up from No. 8, with about $614 billion in assets. The populations in First Horizon's markets are expected to grow about 50% faster than the U.S. national average, offering growth opportunities, TD said. Lawyers have previously said First Horizon could sue for damages if TD calls off the deal, costing Canada's second biggest lender up to hundreds of millions of dollars.
