Why the Ausnet share price has surged 32% in September

Prior to this month, shares in the Aussie company had largely traded between $1.60 and $2 per share for most of the year. However, that all changed on Monday 20 September.

The Ausnet share price rocketed 19.2% higher in the space of one day. The reason? A juicy takeover offer from the world's largest alternative asset manager, Brookfield Asset Management.

Brookfield and associated entities lobbed an offer to acquire 100% of Ausnet shares for $2.50 per share. That represented a 26% premium to Ausnet's closing price on Friday 17 September and a 35% premium to its 30-day weighted average share price.

The unsolicited, indicative, non-binding and conditional proposal sent the Ausnet share price soaring. The revised proposal followed previous bids from Brookfield at $2.35 per share and $2.45 per share.

Ausnet's market capitalisation has swelled to $9.80 billion following the recent takeover bids. It was pushed even higher when news broke of APA Group's (ASX: APA) interest.

The rival electricity distributor one-upped Brookfield's bid with a $2.60 per share conditional offer of its own. The ensuing bidding war between the two groups, including complaints from APA about an exclusivity agreement between Ausnet and Brookfield, has pushed the Ausnet share price higher in September.

Shares in the network infrastructure group have been soaring higher and amongst the ASX 200's top performers this month.
