NOL: Interim Financial Information 30 September 2025

The world's most sophisticated harsh environment offshore fleet

Northern Ocean Ltd. owns and operates two of the world's newest and most capable harsh-environment semi-submersible drilling rigs - Deepsea Bollsta and Deepsea Mira - both ideally suited for operations across all major offshore basins.

With a modern fleet, completed capex programs, and strong commercial and operational execution, the company is well-positioned to benefit from a tightening supply of high-end rigs and an expected increase in long-term demand.

The company's strategic approach has delivered results: Northern Ocean has secured a solid contract backlog with blue-chip clients, while maintaining flexibility to pursue high-value opportunities.

Near-term priorities include closing the Deepsea Bollsta transaction with Odfjell Drilling, securing new contracts for Deepsea Mira, continued focus on operational efficiency and cost control, and preparing for refinancing - all aimed at enhancing earnings and unlocking long-term value for shareholders.

Third quarter 2025 | 3

Deepsea Mira and Deepsea Bollsta are two of the world's most advanced drilling rigs. They are both based on the Moss Maritime CS60 design, capacity of drilling in water depth of up to 10,000 feet, NCS compliant and fully winterized making them capable of drilling in all harsh environment areas globally.

Dear Shareholders,

The third quarter of 2025 marked an important turning point for Northern Ocean.

Operationally, Deepsea Bollsta and Deepsea Mira delivered 117 operating days compared with 89 days in the previous quarter. This provided a 9% increase in operating revenues to USD 57.4 million, although overall financial performance was held back by 64% operational utilization and the planned ramp-up costs associated with new contracts and increased activity across both rigs. Importantly, projected daily operating costs align with our forecasts.

The main operational milestone in the quarter was Deepsea Bollsta's transition from its campaign with OMV Norge to the long-term contract with Equinor on the Norwegian Continental Shelf. The Equinor contract commenced on 31 August, with a firm two-year term and five optional one-year extensions. Excluding client-specific upgrades, integrated services and mobilization, this contract added approximately USD 335 million in firm backlog. Subsequent to quarter end, the firm term was extended with an additional 5-months.

Deepsea Mira commenced a multi-well campaign for Rhino Resources and BW Kudu offshore Namibia. The program provides firm work to the end of 2025 with additional optional scope. The estimated value of this contract was around USD 40 million, which was further extended by an additional firm well post-quarter end.

These achievements total a firm backlog of around USD 382 million as of the date of this report. At the same time, our commitment to cost control and financial discipline remains firm.

Our offshore and onshore teams have delivered complex projects safely and efficiently, including major recertification and upgrade programs, yard stays and mobilizations. I would like to thank the entire NOL team and our partners for their continued dedication and professionalism. Their efforts demonstrate what can be achieved when the right people are in the right place at the right time. This is the backbone of our ability to deliver high-quality operations in some of the world's most demanding environments.

A key strategic development after quarter end was the announced agreement to sell Deepsea Bollsta to an Odfjell Drilling subsidiary for a cash consideration of USD 480

million, with anticipated completion in mid-December 2025. Successful closing of this transaction will allow us to refinance our balance sheet, materially improve capital efficiency and create a solid platform for increased financial flexibility. In light of this, we intend to revert to shareholders with an updated capital allocation plan, including a strategy for return of capital to investors, during the first part of 2026.

Our near-term priorities are therefore clear: (i) closing the Deepsea Bollsta transaction and executing on the associated refinancing and (ii) securing follow-on work and, over time, longer-term employment for Deepsea Mira.

Our strong partnership with Rhino Resources provides a solid short-term base case for Deepsea Mira in the spot market in the Orange Basin, and we expect activity to build further with the anticipated return of several international oil companies to the area in 2026. We are therefore optimistic about the outlook for the rig to stay active in the basin.

We view 2026 as a transition year for the harsh-environment market, with tightening supply of modern units and increased visibility on future drilling programs. Against this backdrop, we expect key long-term contracts for 2027 and beyond to be tendered and awarded during 2026, and believe Deepsea Mira is well positioned to compete for these opportunities.

Sincerely

Arne Jacobsen

Chief Executive Officer

In the third quarter, operating revenue was $57.4 million, up from $52.6 million in the previous quarter. This increase primarily reflects the higher number of operational days for Deepsea Bollsta and Deepsea Mira in the quarter, 117 days in total, compared to 89 days in the previous quarter. Revenue were however negatively effected since the rigs only obtained 64% operational utilization during the quarter.

Total operating expenses were $65.9 million, up from $54.3 million in the previous quarter. The increase in operating expenses is due to the amortization of costs which were deferred in previous periods as a result of the Deepsea Bollsta's commencement of the Equinor contract 31 August. Projected daily operating costs remain in line with expectations.

Administrative expenses amounted to $2.0 million, compared to $1.5 million in the previous quarter. The second quarter figure reflected reversal of some accruals recorded in first quarter.

Interest expense were $15.9 million compared to $15.2 million in the previous quarter.

Foreign exchange loss were $1.4 million, compared to gains of $2.0 million in the previous quarter. This reflects the increase in the FX exchange rate between NOK and USD, although NOL is a USD based company it still has considerable costs in NOK.

The net loss from continuing operations after taxes was $25.9 million, compared to a loss of $15.1 million in the previous quarter. The basic and diluted loss per share for the quarter was $0.09, compared to a loss of $0.05 in the previous quarter.

Third quarter 2025 | 6

On 17 November the Company announced that its subsidiary has entered into an agreement to sell Deepsea Bollsta to an Odfjell Drilling subsidiary for a cash settlement of $480.0 million, effective 15 December 2025.

The proposed transaction is subject to regulatory approval in Norway. The parties expect to conclude the transaction as soon as practicable after obtaining the required approvals.

Successful completion of the transaction will allow NOL to refinance its balance sheet and materially improve capital efficiency, thereby enabling the company to commence the return of capital to shareholders.

Deepsea Bollsta completed its contract with OMV Norge AS on 23 July. Deepsea Bollsta commenced its long term contract with Equinor Energy AS, a subsidiary of Equinor ASA, on 31 August. The contract has a firm two-year period with five optional one-year extensions. This added approximately $335 million in firm backlog and an additional $80.0 million for client specific upgrades, integrated services and mobilization from Namibia to Norway.

On 8 July NOL announced the signing of a contract with a subsidiary of Rhino Resources Ltd. ("Rhino") for the Deepsea Mira for operations in Namibia. The contract included one firm well for Rhino, one firm well for BW Kudu, as subsidiary of BW Energy ASA and three optional wells, with an estimated firm duration of 112 days and a projected value of approximately $40.0 million. Deepsea Mira successfully commenced the contract with Rhino on 29 July.

At the date of this report, the Company's total firm backlog is estimated to be approximately $382.0 million.

Northern Ocean Ltd. owns and operates two modern harsh-environment semi-submersible drilling rigs, with the primary purpose of providing offshore drilling services for the oil and gas industry in harsh environments worldwide.

As of the date of this report, the Company owns Deepsea Mira and Deepsea Bollsta. Deepsea Bollsta completed its contract with OMV Norge AS on 23 July.

Deepsea Bollsta commenced its long term contract with Equinor Energy AS, a subsidiary of Equinor ASA, on 31 August. The contract has a firm two-year period with five optional one-year extensions, this added approximately $335.0 million in firm backlog and an additional $80.0 million for client specific upgrades, integrated services and mobilization from Namibia to Norway.

On 8 July NOL announced the signing of a contract with a subsidiary of Rhino

These consolidated financial statements are prepared under the going concern assumption.

As the Deepsea Mira currently has no long term backlog, the Group's financial position is reliant on securing additional drilling contracts for the rig. This situation potentially gives rise to substantial doubt regarding the Group's ability to continue as a going concern. In the absence of new contract awards, the Group will need to rely on loan amendments, new financing arrangements, and/or equity issuances to meet its loan obligations and working capital requirements over the next twelve months. However, the Board remains confident that a solution will be reached.

The following table provides information about composition of contract revenue:

Resources Ltd. ("Rhino") for the Deepsea Mira for operations in Namibia. The contract included one firm well for Rhino, one firm well for BW Kudu, a subsidiary of BW Energy ASA, and three optional wells, with an estimated firm duration of

112 days and projected value of approximately $40.0 million. Deepsea Mira

successfully commenced the contract with Rhino on 29 July.

At the date of this report, the Company's total firm backlog is estimated to be approximately $382.0 million.

revenue is allocated to the overall performance obligation and recognized ratably over the initial firm term of the related drilling contract.

The following table provides information about the composition of amortization of deferred revenue:

1. RIG OPERATING EXPENSES

   The following table provides information about the composition of rig operating expenses:

   Jan 1 to Sep

   (in thousands of $) Q3 2025

   (in thousands of $) Q3 2025

   30, 2025

   Balance at 31 December 2024	3,861
   Additions to deferred revenue Amortization of deferred revenue	39,748 (5,415)
   Balance at 30 September 2025	38,194
   Short-term deferred revenue Long-term deferred revenue	20,688 17,505

   Note the deferred revenue assets in the balance sheet also contain funds received from the Norwegian government as a grant, due to the Deepsea Mira being equipped with systems which reduce NOx emissions. The grant is being amortized over the estimated useful life of the Deepsea Mira, resulting in annual amortization of $0.1 million. At the date of this report $2.5 million is held as deferred revenue in relation to the NOx grant, split between short-term and longterm.

   Daily operating expenses

   This category includes the costs associated with the daily operations of the rigs. The notable constituents of the daily operating expenses are the expenses for offshore personnel, repairs and maintenance (excluding maintenance projects referred to below), onshore support services, catering costs and management fees payable to Odfjell Drilling.

   Included in daily operating expenses are incremental costs associated with providing customers with add-on services for which the commercial terms differ from those services provided on a reimbursable basis. The costs and the associated revenue for these services are reported on a gross basis under rig operating expenses and contract revenue respectively.

   Maintenance projects

   Maintenance projects which are considered non-recurring and with an individual cost in excess of $100,000 are not considered to be indicative of the ordinary daily running costs of our operations and have been disaggregated from daily operating expenses. These projects are either preventive or corrective in nature.

   Amortization of deferred costs

   Certain direct and incremental costs incurred for upfront preparation, initial mobilization and modifications of the contracted rigs represent costs of fulfilling

   Third quarter 2025 | 16

   
   
   

   a contract as they relate directly to a contract and enhance resources that will be used in satisfying performance obligations. Such costs are deferred and amortized ratably to rig operating expenses as services are rendered over the initial term of the related drilling contract.

   The following table provides information about the deferred costs to fulfill a contract with customers;

   (in thousands of $) Q3 2025

   Balance at 31 December 2024	2,200
   Cost additions	61,689
   Amortization	(4,567)
   Balance at 30 September 2025	59,322
   Short-term deferred costs	32,752
   Long-term deferred costs	26,570

2. INCOME TAXES

   Under current Bermuda law, the Company is not required to pay taxes in Bermuda on either income or capital gains. The Company has received written assurance from the Minister of Finance in Bermuda that, in the event of any such taxes being imposed, the Company will be exempted from taxation until 31 March, 2035.

   Other jurisdictions

   The Company has subsidiaries, which are incorporated in the Marshall Islands and are not subject to income tax. Certain of the Company's subsidiaries and branches in Norway, Ireland, Namibia, Cyprus and the U.S. are subject to income tax in their respective jurisdictions.

   Deferred tax

   Deferred tax assets and liabilities are based on temporary differences that arise between carrying values of assets and liabilities used for financial reporting

   purposes and amounts used for taxation purposes and the future tax benefits of tax loss carry forwards.

   The Company does not have any unrecognized tax benefits, material accrued interest or penalties relating to income taxes.

   Third quarter 2025 | 17

   
   
   
3. EARNINGS PER SHARE

   The computation of basic earnings per share is calculated by dividing the net loss attributable to the Company by the weighted average number of shares outstanding during the period.

   Diluted earnings per share amounts are calculated by dividing the net income attributable to the Company by the weighted average number of shares outstanding during the year plus the weighted average number of ordinary shares that would be issued on conversion of all the dilutive potential ordinary shares into ordinary shares. If in the period there is a loss then any dilutive potential ordinary shares have been excluded from the calculation of diluted loss per share, as their effect would be anti-dilutive.

   The components of the numerator and the denominator in the calculation are as follows:

   Q3 2025 Jan 1 to Sep 30, 2025 Jan 1 to Sep 30, 2024 Q3 2024 2024

   Net loss (in thousands of $) Weighted average number of ordinary shares (in thousands)	(25,888) 303,215	(52,193) 303,215	(51,832) 216,505	(35,890) 273,215	(65,657)

   Third quarter 2025 | 18

   
   
   
4. RESTRICTED CASH

   As of 30 September 2025, restricted cash of $0.2 million consists of funds held for an NIS guarantee and payroll taxes.

5. DEFERRED COST AND DEFERRED REVENUE

   At the end of the third quarter Deferred cost and Deferred revenue relating to the Equinor contract for Deepsea Bollsta, were $59.2 million and $39.8 million respectively. The net amount will be a cost when Deepsea Bollsta is sold 15 December 2025.
