Pharmaceuticals giant Shire is also among the FTSE 350 companies reporting. The second quarter results will be complicated by the merger of Baxalta on 3 June, according to Deutsche Bank."However, we expect the company to report pro forma combined revenue growth of 10% and our forecasts imply pro forma non generally accepted accounting principles (GAAP) earnings before interest and tax (EBIT) growth of 8%," the bank said."We expect focus to be on possible updated synergy targets and guidance."Baxalta revenues are expected to have risen 11% at a constant exchange rate, reflecting growth in its Immunology and Hematology divisions, along with a positive contribution from the portfolio acquisition of blood cancer drug Oncospar.Deutsche Bank said Shire's second quarter results should also benefit from strong year-on-year growth in US prescriptions of central nervous system stimulant, Vyvanse, and ulcerative colitis treatment, Lialda.
