Bloomsbury Publishing has forecast that its full-year profit will be well ahead of expectations, encouraged by the robust demand for it fantasy novels and academic digital resources.
"Throughout a year which has been characterised by rising inflation and cost of living pressure, it is notable that reading remains hugely popular throughout the world, with books regarded by many readers as an affordable pastime," chief executive Nigel Newton said in a statement.
The London-listed publisher is best known for picking up JK Rowling's Harry Potter series in 1997 after its rejection by a dozen others.
It said it expected profit before tax for the year ended February 28 to be about £30m.
This compared with the company compiled analyst consensus of 26.9 million pounds.
British author Samantha Shannon's political fantasy novel "A Day of Fallen Night" became an instant bestseller worldwide after its release in February, while American fantasy author Sarah J. Maas' titles continued to see strong sales, the publisher said.
The company added that it expected revenue to be over £260m, while analysts currently expected it to be about £242.6m.
