That's slightly slower than local brokerage First NZ Capital is picking, with analyst James Schofield projecting positive operating earnings in 2018 and a bottom line profit the following year. He also has a $21 price target for the stock.
Morningstar's James and Lange said a potential takeover bid by accounting software groups Intuit or Sage is underpinning the share price, though would be more likely to come from North America's Intuit, which has the scale to take over a rival and become dominant in Australia, as UK-based Sage has been pulling back from acquisition-led growth.
Xero estimated the long-term value (LTV) of its existing subscribers at more than $2 billion as at March 31, based on future cash flows and excluding customer acquisition costs, they said.
"If an acquisition were to proceed, it is unclear how much cost reduction an acquirer could undertake, but we expect it would be significant, considering gross margins are around 80 percent," James and Lange said.
"We expect an acquirer would be prepared to pay at least the value of capital invested in the business to date, around $500 million, and expect a lower limit of around $1 billion, or a 50 percent discount to the LTV figure."
The software company's current market value is $2.53 billion, and at Morningstar's target price it would be worth $2.88 billion.
Xero reported an annual loss of $82.5 million in the 12 months ended March 31 on revenue of $207.8 million, saying it had enough cash on hand to start breaking even without having to raise more capital.
The software developer has eschewed chasing profits in the short-term, instead spending cash to build a global-scale business. As at March 31, it had built a customer base of 717,000 paid subscribers from 475,000 a year earlier.
Morningstar expects rapid customer growth will continue, and by 2021 it estimates Xero will have 80 percent of New Zealand's market, 48 percent of Australia, 21 percent of the UK and 5 percent of the US. Once it starts turning a profit, James and Lange anticipate Xero will pay dividends of 10 cents per share.
