Peel Hunt has cut its earnings by 30% for Hikma Pharma, while the price target falls to £13.90 from £21.50.
The downgrades were made in the wake of last week's profit warning. The interim results revealed the firm had been hit by a further downturn in the fortunes of its generics business.
Peel's recommendation remains 'hold'.
"The shares have been swift to discount these incremental concerns (the stock is down around 15% since the first-half release); so upside to our target price remains despite our downgrades, keeping us at hold," the broker said in a note to clients.
