A gaggle of health-care businesses going public promises to make next week the busiest of the year for U.S. listings.

Ten companies -- the most since November -- are expected to price next week, with nine of them in the health-care sector, according to data compiled by Bloomberg that excludes special purpose acquisition companies, real estate investment trusts and funds.

The listings are on the small side, averaging about $84 million compared with $288 million for deals already priced this year.

Autolus Therapeutics Ltd., which is developing cancer therapies, is set to be the largest, with a targeted offering size of $133 million at the high-end of the marketed range. Magenta Therapeutics Inc. and Eidos Therapeutics Inc. follow, with both aiming to raise up to about $106 million.
