Traders have spent this year trying to flush out takeover deals for water groups including Pennon and United Utilities. But yesterday experts at HSBC washed out any hope of M&A, blaming regulatory uncertainty as the cause.
The shares in the water groups have trickled upwards on hope of consolidation and HSBC points out that both United Utilities and Severn Trent are trading on a 12 and 13 per cent premium to March 2014. But it thinks the "exuberance of the market for M&A should be tempered" ahead of a review of capital structures set by the water and sewerage provider regulator Ofwat.
Instead, HSBC advises any would-be suitors to "wait for visibility on Ofwat's approach to high leverage and to acquiring assets at the beginning of the next year period in 2015, giving four years benefit of the cost of capital differential."
Pouring cold water on bid talk was followed by a 10.5p dip in Pennon to 675p, but United Utilities dribbled up 5p to 745.5p
HSBC's note came as the energy regulator Ofgem launched an investigation into six suppliers over failing to meet all the targets on providing consumers with efficiency measures.
Ofgem said energy providers had achieved 99 per cent of the targets but Centrica's British Gas, Drax, Scottish Power and SSE had missed targets.

Over on the mid-cap index it was Ophir Energy's time to shine. Nearly a year after making a gas discovery off the coast of southern Tanzania, yesterday the African-focused explorer reported better than expected results. Ophir's partner BG Group, which has been investing in the region, will also benefit.
The news also reassured those who were concerned that Ophir had passed its best – its shares declined this year from highs of 650p last year.
In February Britain's richest man, the Indian steel tycoon and Queens Park Rangers part-owner Lakshmi Mittal, sold half of his stake at 475p.

Ophir was 1.6p better off at 408.5p and BG added 5p to 1,089.5p.
