Newcastle have announced a post-tax profit of £9.9m for the year ending June 2013.
The figure represents an £8.5m increase in profit on the previous 12 months and, according to Newcastle, is down to "player trading, a strong commercial performance and a significant reduction in operational losses".
Newcastle made a £10.6m profit on player sales, the bulk of which came from the sale of Demba Ba to Chelsea, although £28.7m was paid in transfer fees on the likes of Mathieu Debuchy, Yoan Gouffran and Moussa Sissoko.
A 24.2% increase in commercial revenue drove overall turnover up to £95.9m, while matchday turnover was also up and operational losses significantly down - from £5.1m to £616,000.
A statement from the club's directors made it clear they believe a long-term strategy of financial responsibility will bring rewards - despite renewed criticism of owner Mike Ashley in the wake of Yohan Cabaye's recent departure.
The statement read: "As supporters will be aware, finances are a significant issue for all football clubs given the introduction of Financial Fair Play into the Premier League in addition to UEFA's Regulations.
"Complying with FFP continues to be a key influence on strategy and something we have been working hard at over a number of years.
"Everyone at this club wants to finish as high up the Barclays Premier League table as they possibly can. If the club can sustain itself as a 'top ten' team year-on-year with a stable structure and the right finances, it gives itself every chance of pushing even further.
"Matchday and commercial revenue is a key driver because that's where the club can compete with - and outperform - its competitors to enhance its spending capabilities.
"The process requires patience but we remain absolutely committed to growing the club in a responsible and sustainable way."
