City shop Finsbury picks up listing brief for Nat Rothschild's Vallar

The company is seeking to raise £600m through an initial public offering on the main market of the London Stock Exchange and will use the funds to make a ‘significant’ investment in the mining sector.

Finsbury’s involvement will be led by partner Edward Simpkins.

The City agency was appointed without a competitive pitch, having worked personally with Rothschild for a number of years. Finsbury advised Atticus Capital, an investment firm Rothschild was previously co-chairman of, and he has a lengthy working relationship with Finsbury founder Roland Rudd.

Rothschild has set the firm up alongside James Campbell, a former chairman of Anglo–American's coal division.

Those involved in the IPO are confident they can drum up sufficient investor interest to raise £600m, but a number of previous flotations have floundered already this year.

The listing was the second in a matter of days, with fellow City heavyweight Brunswick leading Ocado's planned flotation announced last week.
