It noted that Marshalls outperformed the FTSE 250 by 10x and traded at 18x average price-to-earnings, a premium of around 40% to peers from 2013 to 2021.

RBC said earnings per share and return on capital employed increased by around 3x.

"Enter Marley, a transformational deal which coincided with a cyclical downturn in 2022. 2024e adjusted EPS is over 50% below ‘normalised’ levels," it said.

Marshalls bought pitched roof tile specialist Marley Group for £535m.

"Prior CEO Martyn Coffey departed and now we await a new midterm strategy. We think a pathway back towards pre-Marley ROCE and above market earnings growth is needed to justify prior valuation levels. Marshalls' premium remains in-tact despite lower adjusted EPS growth and ROCE."
