Celtic made a pre-tax profit of almost £10million last season after a near 50% jump in revenue.
The Scottish champions have announced a profit before tax of £9.74million in the year to the end of June 2013.
Celtic, boosted by their run to the last 16 of the Champions League, brought in group revenue of £75.8million, up 48 per cent on the previous 12 months.
Operating expenses were up 15.2% while Celtic plc wiped out their bank debt.
The company had £3.76million in the bank at the end of the period following a bank debt of £2.77million 12 months earlier.
The importance of Champions League revenue of more than £20million was evident when compared to the previous year, when Celtic were in the Europa League and recorded a deficit of more than £7million.
The figures do not take account of the sale of Victor Wanyama, Gary Hooper and Kelvin Wilson in the summer, which brought in around £20million.
They do encompass the purchases of Virgil van Dijk and Amido Balde earlier in the summer.
