Stem agreed to purchase Also Energy Holdings, a privately held company, in a deal worth $695m in cash and stock.

According to a joint press release issued on Thursday, the merger will fuse Stem’s storage optimisation capabilities with AlsoEnergy’s solar asset performance monitoring and control software.

Stem will pay 75% of the total consideration in cash and approximately 25% in Stem common stock.

In early trading on the NYSE, Stem stock jumped 5.30% to around $18.90.

In the release, Stem CEO John Carrington said the combined business will bring unique software, controls and analytics capabilities to speed up the energy transition to a more renewable, decarbonised future.

“As the battery storage and solar industries continue to experience tremendous global growth, developers, asset owners and utilities will increasingly look to our combined software capabilities to provide a unified platform for energy intelligence that improves project performance,” he said. “This acquisition underscores our focus on expanding Stem’s global reach and delivering high margin, market-leading software products to our customers”.

Solar future

The businesses hope the transaction will speed up Stem’s growth and extend the company’s global reach, while providing recurring software revenue and bigger margins.

The combination will also add 32.5 gigawatts of solar assets across 50 countries to Stem’s existing software services platform.

The difference between trading assets and CFDs
The main difference between CFD trading and trading assets, such as commodities and stocks, is that you don’t own the underlying asset when you trade on a CFD.
You can still benefit if the market moves in your favour, or make a loss if it moves against you. However, with traditional trading you enter a contract to exchange the legal ownership of the individual shares or the commodities for money, and you own this until you sell it again.
CFDs are leveraged products, which means that you only need to deposit a percentage of the full value of the CFD trade in order to open a position. But with traditional trading, you buy the assets for the full amount. In the UK, there is no stamp duty on CFD trading, but there is when you buy stocks, for example.
CFDs attract overnight costs to hold the trades (unless you use 1-1 leverage), which makes them more suited to short-term trading opportunities. Stocks and commodities are more normally bought and held for longer. You might also pay a broker commission or fees when buying and selling assets direct and you’d need somewhere to store them safely.
