Melrose Industries PLC (LSE:MRO, OTC:MLSPF) interim results due on 7 September will be its first as a pure aerospace company, after spinning out Dowlais Group PLC (LSE:DWL) in April.
Analysts expect first-half revenue of £1.68 billion, according to a Bloomberg compiled consensus, underlying profits (EBITA) pre PLC costs of £170 million and an EBITA margin of 10.1%.
Barclays noted that read-across from fellow engine-exposed aerospace companies reported growth in aftermarket revenue of 27% in the second quarter, with companies like Safran and GE outperforming sector peers.
But all eyes are on "the GTF issue", said analyst Jonathan Hurn, referring to Pratt & Whitney's more efficient new aircraft engine and Melrose liability under its 4% revenue and risk sharing partnership (RRSP) on the PW1100.
Assuming Melrose is fully liable for its share, then Barclays' base case is a £47 million liability, equivalent to circa 3.5p a share, however, it could be lower and "in the total scheme of things and compared to other members of the RRSP, the impact appears minimal".
Elsewhere, the analyst said areas of focus will be on underlying margins, progress on the repricing of the defence contracts within the Structures business, further detail on the timing of the cash return via the start of the buyback, whether performance was impacted by any supply chain issues, phasing of restructuring benefits, and the effect of a strengthening US dollar on the outlook.
Barclays also noted that Melrose looks like being added to the MSCI Europe Index.
