Financial results for the year ending July 2013 show a pre-tax surplus of £100,000, halting two consecutive years of substantial losses - £1m in 2012 and £900,000 in 2011.
Hibs have largely credited the upturn in finances to an improved performance in the Scottish Premier League last season, finishing seventh compared to 11th in the 2011/12 campaign.
Season-ticket sales also rose from 7000 to 8000 and the modest profit posted, allied with scheduled loan repayments, have resulted in a fall in net debt from £6.4m to £5.5m.
Petrie welcomed the figures which, he says, helped finance the signing of 10 players this summer but he acknowledges the club needs results on the field as well as on the balance sheet.
"We have brought in players who, by and large, have experience of the Premier League," said Petrie, whose team have had a sluggish start to the campaign. "They have bought into the vision here and we need to see that group of players deliver."
Hibs' turnover also shows a substantial improvement, with the club banking £8m over the course of the year, up from £6.9m for the year ending July 2012, while cost-cutting has also been implemented.
Staff costs have been cut by £200,000, down to £3.9m. As a consequence, Hibernian boast their lowest wage-to-turnover ratio since 2007, reduced from 60% to 49%.
Petrie, however, says the support of fans is what will ultimately "define" the club's success. Hibernian's annual meeting will take place at Easter Road on October 1.
