Updates from Aggreko, Spire Healthcare and Caledonia Investments

Greek debt worries ensured little forward movement for the FTSE 100 on Friday, ending just 2.5 points higher at 6,710.4. TUI AG and ARM Holdings were up 2.9% and 2.7% to 1156p and 1118p; Hikma Pharma surged 2.7% also. Miners Fresnillo and Glencore dipped 2% and 1.7% (to 712.50p and 271.55p).

Over in the US the Dow Jones slipped 100 points, or 0.55%, to 18,015.9 though it was still up 117 points on the week, part-helped by indications from the Fed that interest rates aren't likely to rise yet. Home Depot was Friday's biggest climber, up 0.52%.

We start with commercial generator hire player Aggreko - recently demoted from the FTSE 100 - claiming it will shift from its current regional structure to operate as two business units: Aggreko Rental Solutions and Aggreko Power Solutions.

The re-jig means Aggreko Rental Solutions will incorporate its local businesses in developed markets while Aggreko Power Solutions will include existing Power Projects business and its local businesses in developing markets, it says.

"We have taken," says boss Chris Weston of the Glasgow-based company, "the decision to reorganise the business to be as efficient and as effective as we can be for our customers and our markets."

Next, Remgro is snapping up a 29.9% stake in SpireHealthcarefrom Cinven for 360p per share or £432m. The intention is for South Africa-based hospital group Mediclinic - Remgro is its biggest share holder - to acquire the stake shortly.

Mediclinic and Spire have agreed to explore ways in which they can work together they claim. Remgro, or in due course Mediclinic, will have the right to nominate a director to the Board.

Mediclinic and Remgro claim no current intention of making an offer for all of Spire. "This is an exceptional opportunity," says Spire boss Robert Roger, "for us to gain a strategic investor who understands our business and growth."

Lastly, Caledonia Investments says it's buying a majority stake in Seven Investment Management fund management in a deal which values 7IM at £100m. 7IM was established in 2002 and at the end of April it had assets under management of £9.5bn.

Caledonia will invest up to £77m in cash to acquire 94% of 7IM. For the financial year to 31 December 2014, 7IM reported profits before tax of £8.6m.

"We are delighted," says 7IM boss Tom Sheridan, "to be partnering with Caledonia in the next phase of 7IM's development. Their investment philosophy and culture, as well as their attitude to longer term investment, are perfectly aligned with our own."
