Thank you, Faizan. [Foreign Language] everyone. So I'll share with you the financial highlights. We go through the quarter numbers, followed by the figures. For revenue, MISC Berhad recorded a decrease in revenue of $162 million in quarter 4 compared to the corresponding quarter. Since reduction was primarily driven by the offshore business, the strong decline in construction revenue attributed to FPSO Marechal Duque de Caxias, which reached its first oil in quarter 4 last year.
Following this, revenue from ongoing construction activities tapered off, resulting in a lower revenue contribution from this segment in quarter 4, 2024. Additionally, the Heavy Engineering segment also experienced a revenue decline. This was due to several projects in the segment nearing completion, which led to the reduced activity and therefore, a decrease in revenue for the quarter.
Against the preceding quarter, higher revenue in the current quarter compared to the preceding quarter [Technical Difficulty] of construction revenue for floating storage unit in our Gas segment and revenue recognition from the commencement of a charter hire for FPSO Marechal Duque de Caxias in the Offshore segment after the successful production of first oil at the end of October 2024.
For the operating profit, the group reported a decrease in operating profit by USD 98 million in current quarter primarily attributable as well as the Gas segment. The Offshore business segment recorded an operating loss as compared to operating profit in the same quarter last year. This was primarily due to the lower project progress as well as increased [Technical Difficulty]. Meanwhile, the decline in operating profit for Gas segment was due to higher receivable impairment in the current quarter.
On a positive note, the Heavy Engineering segment contributed to a higher operating profit on which the improvement was driven by the recognition of cost recovery claim, which partially helped to offset a decline in the earlier 2 segments.
Against the preceding quarter, the group operating profit declined quarter-on-quarter by USD 36 million, primarily driven by the high cost provision for Offshore business segment as well as a higher receivable impairment for Gas segment as I stated earlier.
The profit after tax, MISC recorded a group loss after tax of $91 million for the current quarter as compared to the profit after tax in both corresponding and preceding quarter. The primary driver behind this shift was the high impairment provision in Gas segment which further exacerbated the lower operating profit in the current quarter, leading to overall loss after tax.
Excluding impairment, the group reported an adjusted profit after tax of $71 million in current quarter, 53% lower than the -- of the same period last year as well as 60% lower compared to the preceding quarter.
CFFO, higher cash flow from operation in the current quarter by $27 million as compared to corresponding quarter, mainly higher collection on the Offshore business segment coming from the operation of our FPSO Marechal Duque de Caxias.
Against preceding quarter, cash flow from operation was higher in the current quarter by $169 million, mainly from the high collection of our offshore business as well as Drilling and Heavy Engineering segment.
For the full year, MISC Berhad recorded a decrease in revenue by USD 230 million compared to the corresponding year. This reduction was primarily attributed by the Offshore business segment, which saw a decline in construction revenue attributed to FPSO Marechal Duque de Caxias, which reached its completion on 31st October. As the project reached completion, the associated revenue from ongoing construction activities tapered off, resulting in a lower revenue contribution from this segment in the current year.
The group operating profit of $568 million, which was lower than the previous year operating profit of $631 million. The decline was mainly due to the profit in the Offshore business segment, followed by a lower project progress as well as a higher cost provision.
Additionally, the Gas segment also recorded a low operating profit from lower earnings base and charter rates, coupled with higher receivable impairment. The decline was partially offset by the Petroleum segment benefited from higher margins contributed positively to the overall performance coupled with stronger performance in Heavy Engineering segment.
The segment returned to black in current year as compared to operating loss in the same period last year. The improvement was driven by recognition of cost recovering claims and better cost discipline.
MISC Berhad recorded a group profit after tax of $270 million in current year, 37% lower than the corresponding year due to low operating profit and high impairment provision in the Gas segment, which had a significant impact on the overall profit.
Excluding impairment, the group reported a profit after tax of $443 million, which narrowed the adverse gap between the current year against corresponding year and CFFO against prior year, cash flow from operation was lower in the current quarter, mainly due to the one-off FSE prepayment that took place in 2023. Excluding the one-off repayments, CFFO was only lower by 10%, and this is due to the high payments made to the creditors this year.
Our balance sheet, total asset as at December '24 compared to December '23, mainly due to the amortization of finance fees income, impairment and depreciation charge, which led to the reduction in asset value. Total liabilities reduced over the same period, primarily due to higher net repayments and [Technical Difficulty] year. As a result of the lower liabilities and the higher repayment of borrowings, the group gearing ratio has improved as of December 2024.
As mentioned earlier, our debt balance as of December 2024 was lower as compared to December 2023, followed by the higher net repayment of loans and borrowings, while the decline to the cash balance as of December '24, resulting from the higher payment to creditors in addition to the higher net repayments of loan and borrowings, partly offsetting the low payment of CapEx in the year.
So these are additional information analysis that we are sharing with all of you. So if you look -- I'll just give you an incremental information on here. If you look at Gas segment, we recorded $128 million profit -- or loss after tax in quarter 4 of 2024, that is because of the one-off asset impairment of $161 million in [indiscernible] in quarter 4. If we were to remove that, the normalized PAT would have been $33 million, which is comparable to at least the preceding quarter in quarter 3 of 2024.
The financing for the offshore business, the financing cost is about $26 million, right? And for both Petroleum and Heavy Engineering provided a very strong performance with higher vessel utilization for petroleum and cost discipline for both Petroleum and Heavy Engineering.
Next. So for the full year, similarly, if you look at the Gas segment, if we were to remove the asset impairment of $173 million, the profit would have been $173 million compared to $74 million in the previous year, right? And for the offshore business, this included in the $92 million loss for the offshore business financing of $110 million.
I think that's all that I have for the financial [indiscernible]. Thank you.
