Future Listings

Large-cap floats dominated the narrative last week as far as news about upcoming ASX IPOs. With a total of seven billion-dollar plus floats on the way to the local market, it was a case of details being ironed out for a number of names including digital bank Judo Bank, disability services provider APM, essential services provider Ventia, hotel bookings platform SiteMinder, and also steel distributor Vulcan, which falls just short of the $1 billion mark.In terms of prospective listings on the horizon, renewable energy technology firm RedEarth is emerging as a candidate. The company supplies solar-charged batteries allowing private households to act as a power plant by selling stored energy to other members on the RedEarth grid.More immediately, however, is Close the Loop Group, a manufacturing, recycling and urban mining company that is listing amid a merger with packaging firm O F Packaging. Eyeing $12 million in fresh funds, the company has pivoted from a printer cartridge and toner recycling business into a much broader firm involved with repurposing and reselling recyclable parts and products. Close the Loop generated $13.2 million in EBITDA in FY21.Lastly, marketing platform Tribe is putting the finishing touches on IPO plans of its own. The platform is designed to connect influencers and marketers to distribute content. A number of household brands have used the platform to run campaigns across social media, ecommerce, digital ads and the like.One name that might raise a few eyebrows in the US is Hertz Global Holdings, with the car rental company set to re-IPO. On the back of strong consumer demand, and a shortage of rental cars, prices have been a major tailwind for the company most-recent results. The company emerged from bankruptcy a few months ago, and to date has been listed via OTC markets. With the sector showing strength as travel ramps up, and its adjusted EBITDA leaping, the business will eye a return to either the Nasdaq or NYSE by the end of the year.Outside of Hertz, no major names announced IPOs in the US last week, but that didn't necessarily deter a number of smaller-cap names from submitting filings to list in the coming weeks. This includes laser hair removal company Milan Laser, expense management platform Expensify, and health food brand The Real Good Food Company.
