The shares rose 16.5 per cent to $5.30, valuing the company at $1.46b.
Investors looked through a 15 per cent decline in net profit to US$16m, with the year-earlier figure flattered by a one-off tax benefit and deferred spending on research and development.
The company has been one of the beneficiaries of Covid-19 restrictions as its church customers relied on live-streaming and digital giving to replace traditional services.
"Pushpay expects the increase in digital giving as a proportion of total giving resulting from Covid-19 to outweigh any potential fall in total giving to the US faith sector," it said.
Some US$5b of payments were processed through its platform in the period, up from US$3.6b a year earlier, while customer numbers climbed 42 per cent to 10,896. Its monthly average revenue per customer was largely unchanged at US$1,317.
Pushpay completed its US$87.5m acquisition of Church Community Builder in December, adding a new platform that churches use to interact with their members and oversee basic administration.
The company said it's also eyeing other potential acquisitions to broaden its suite of services, noting that its rising cash flow gave it the flexibility to do so.
Operating cash flow climbed to US$23.5m in the year from US$2.8m. After financing and investment spending, Pushpay had US$7.2m in the bank.
Operating expenses rose just 5 per cent to US$65.7m, while product design and development costs were up 1 per cent at US$17.2m.
Pushpay's workforce grew to 459 at the end of March from 389 a year earlier, largely due to the addition of Church Community Builder. Of that, 101 staff are in New Zealand and 358 in the US.
