ALTERA INFRASTRUCTURE L.P. AND SUBSIDIARIES

NOTES TO THE UNAUDITED INTERIM CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

As at September 30, 2021 and December 31, 2020 and for the three and nine months ended September 30, 2021 and 2020

(all tabular amounts stated in thousands of U.S. Dollars, except unit and per unit data)

1.Nature and Description of the Partnership

Altera Infrastructure L.P. and its wholly-owned or controlled subsidiaries (collectively, the Partnership) is an international infrastructure services provider to the offshore oil and gas industry, focused on the ownership and operation of critical infrastructure assets in offshore oil regions of the North Sea, Brazil and the East Coast of Canada. The Partnership was formed as a limited partnership established under the laws of the Republic of the Marshall Islands in August 2006 and the Partnership's affairs are governed by the Marshall Islands Limited Partnership Act and its limited partnership agreement as amended. The Partnership is a subsidiary of Brookfield Business Partners L.P. (NYSE: BBU) (TSX: BBU.UN) (or with its affiliates, Brookfield).

The Partnership’s preferred equity units are listed on the New York Stock Exchange under the ticker symbols “ALIN PR A”, “ALIN PR B” and “ALIN PR E” respectively.

The registered head office of the Partnership is Altera House, Unit 3, Prospect Park, Arnhall Business Park, Westhill, Aberdeenshire, AB32 6FJ, United Kingdom.

2.Significant Accounting Policies

a.Basis of presentation

These unaudited interim condensed consolidated financial statements of the Partnership have been prepared in accordance with International Accounting Standard 34 - Interim Financial Reporting (or IAS 34), as issued by the International Accounting Standards Board (or IASB). These interim condensed consolidated financial statements do not include all the information and disclosures required in annual financial statements, and should be read in conjunction with the Partnership’s annual consolidated financial statements as at and for the year ended December 31, 2020, which are included in the Partnership's Annual Report on Form 20-F for the year ended December 31, 2020. The unaudited interim condensed consolidated financial statements have been prepared under the assumption that the Partnership operates on a going concern basis and have been presented in U.S. dollars rounded to the nearest thousand unless otherwise indicated.

The accounting policies adopted in the preparation of these interim condensed consolidated financial statements are consistent with those followed in the preparation of the Partnership’s annual consolidated financial statements as at and for the year ended December 31, 2020, except for the adoption of new standards and changes in the Partnership's accounting policies effective as of 1 January 2021, as described below in Note 2c. There have been no significant changes to the method of determining significant estimates and judgments since December 31, 2020.

These unaudited interim condensed consolidated financial statements were approved by management and authorized for issue on November 5, 2021.

b.Going concern

As at September 30, 2021, the Partnership had a working capital deficit of $477.9 million primarily relating to scheduled maturities and repayments of $565.9 million of outstanding borrowings during the 12 months ending September 30, 2022, which amounts were classified as current as at September 30, 2021.

The working capital deficit of $477.9 million as at September 30, 2021, has increased from $230.5 million as at December 31, 2020. The increase in the working capital deficit was primarily due to a decrease in financial assets of $67.2 million mainly relating to amounts held in escrow for a shuttle tanker newbuilding yard installment payment as at December 31, 2020, a decrease in accounts receivable and other of $45.1 million, an increase of debt repayments of $203.9 million mainly due to the maturity of the Partnership's $250 million senior unsecured bonds due in the third quarter of 2022 and and increase in related party borrowings $53.5 million, partially offset by a decrease in other financial liabilities of $157.1 million primarily due to the termination or amendment of certain interest rate swaps during the nine months ended September 30, 2021 and accounts payable and other of $14.6 million.

Based on these factors, the Partnership will need to obtain additional sources of financing, in addition to amounts generated from operations, to meet its obligations and commitments and the minimum liquidity requirements under its financial covenants. During the three months ended September 30, 2021, the Partnership completed various measures to improve its debt maturity profile and enhance its liquidity and financial flexibility. See Notes 12a and 16 for additional information. Other potential sources of financing that the Partnership is actively pursuing, or may consider pursuing, during the one-year period to September 30, 2022, include entering into new debt facilities, borrowing additional amounts under existing facilities, the refinancing or extension of certain borrowings, selling certain assets, seeking joint venture partners for the Partnership's business interests and/or capital raises. Additional potential sources of amounts generated from operations include the extensions and redeployment of existing assets.

The Partnership is actively pursuing financing initiatives described above, which it considers probable of completion based on the Partnership’s history of being able to raise and refinance borrowings for similar types of vessels and based on the Partnership's assessment of current conditions and estimated future conditions. The Partnership is in various stages of progression on these matters.

Based on the Partnership’s liquidity at the date of these unaudited interim condensed consolidated financial statements, the liquidity it expects to generate from operations over the following year, and by incorporating the Partnership’s plans to increase its liquidity that it

NOTES TO THE UNAUDITED INTERIM CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

As at September 30, 2021 and December 31, 2020 and for the three and nine months ended September 30, 2021 and 2020

(all tabular amounts stated in thousands of U.S. Dollars, except unit and per unit data)

considers probable of completion, the Partnership expects that it will have sufficient liquidity to enable the Partnership to continue as a going concern for at least the one-year period to September 30, 2022.

c.New standards, interpretations, amendments and policies adopted by the Partnership

The Partnership has not early adopted any standard, interpretation or amendment that has been issued but is not yet effective.

i.Interest Rate Benchmark Reform — Phase 2 (Amendments to IFRS 9, IAS 39, IFRS 7, IFRS 4 and IFRS 16)

In August 2020, the International Accounting Standards Board published Interest Rate Benchmark Reform — Phase 2 (Amendments to IFRS 9, IAS 39, IFRS 7, IFRS 4 and IFRS 16) (or Phase 2 Amendments), effective January 1, 2021. The Phase 2 Amendments provide additional guidance to address the issues that will arise during the transition of benchmark interest rates and primarily relate to the modification of financial assets, financial liabilities and lease liabilities where the basis for determining the contractual cash flow changes as a result of the replacement of an existing interest rate benchmark, allowing for prospective application of the new applicable benchmark interest rate, and to the application of hedge accounting, providing an exception such that changes in the designation of hedge accounting relationships that are needed to reflect the changes required by the benchmark interest rate reform do not result in the discontinuation of hedge accounting. The Partnership adopted the Phase 2 Amendments on January 1, 2021. The adoption of the amendments did not have an impact on the Partnership's unaudited interim condensed consolidated financial statements as at and for the three and nine months ended September 30, 2021. The Partnership's risk management strategy has not changed as a result of these matters.

Progress towards implementation of alternative benchmark interest rates

The Partnership is exposed to the impact of interest rate changes, primarily through its floating-rate borrowings that require it to make interest payments based on LIBOR. The Partnership uses interest rate swaps to reduce its exposure to market risk from changes in interest rates.

The Partnership plans to transition the majority of its LIBOR-linked contracts to risk-free rates through amendments to fallback clauses in its floating-rate credit facilities and debt instruments which would change the basis for determining the interest rate cash flows from LIBOR to a risk-free rate at an agreed point in time. During March 2021, ICE Benchmark Administration, an administrator of regulated benchmarks, announced that it has delayed the cessation of the publication of the overnight, one, three, six and 12 month USD LIBOR until June 30, 2023.

Interest rate benchmark transition for non-derivative financial liabilities

As at September 30, 2021, the Partnership had $1.7 billion of outstanding LIBOR-referenced borrowings summarized as follows:


	Principal	Weighted-average term	Transition Progress
	$	(years)
Revolving Credit Facilities	361,411	2.39	Expected to amend fallback clauses prior to cessation of publication of LIBOR.
Term Loans	1,122,197	4.10
Public Bonds	200,000	3.05
Total	1,683,608	3.61

Interest rate benchmark transition for derivatives

As at September 30, 2021, the Partnership had an outstanding notional balance of $0.6 billion of LIBOR-referenced interest rate swap agreements.

For all of the Partnership’s LIBOR-referenced derivatives, the International Swaps and Derivative Association’s fallback clauses were made available in late-2020 and the Partnership and its counterparties expect to adhere to this protocol. Such adherence would result in all legacy trade under the derivatives following, on the cessation of LIBOR, the fallback clause provided in the protocol.

ii.Segments

As at January 1, 2021, the Partnership modified the cost allocations between its operating segments. The Partnership's components of the business for which discrete financial information is reviewed to assess performance and make decisions regarding resource allocation is still based upon five operating segments. However, the allocation of certain expenditures, relating to direct operating costs and general and administrative expenses, has been modified to show the impact of certain corporate direct operating costs in the corporate segment before reallocation to the operating segments. Additionally, certain expenditures that relate directly to corporate activities will be retained within the corporate segment. Previously all of these expenditures were allocated directly to the five operating segments based on an estimated use of corporate resources. The 2020 comparative information has been restated as a result of this change and the modifications have been deemed to not be material for all operating segments and all periods presented.

(all tabular amounts stated in thousands of U.S. Dollars, except unit and per unit data)

iii.Estimation uncertainty

COVID-19

The Partnership has not identified any new significant developments related to the COVID-19 pandemic which would impact key critical judgments, estimates and assumptions that affect the reported and contingent amount of assets, liabilities, revenues and expenses, including whether any additional indicators of impairment were present for the three and nine months ended September 30, 2021. The Partnership will continue to monitor the COVID-19 situation and review its critical estimates and judgements as circumstances evolve.

iv.Related Party Borrowings Reclassification

The accounting policy elected historically by the Partnership has reflected its long-term debt within two line items, Borrowings and Due to related parties. Borrowings has included publicly listed debt held by third parties and by Brookfield. The related party component of publicly listed Borrowings has been historically disclosed in the notes to the financial statements.

On August 27, 2021, the Partnership completed a refinancing with Brookfield (or the Brookfield Exchanges) (see Note 12a for additional information) and voluntarily revised the Partnerships accounting policy to classify all debt held by Brookfield, regardless of the nature of the instrument as Due to related parties. The Partnership believes it is preferable to have a consistent practice in showing all related party debt on the same financial statement line items.

The Partnership has reflected this change retrospectively by restating its comparative consolidated statement of financial position. Following the change, debt will continue to be included in two line items, Borrowings, which will include only debt held by third-party counterparties and Due to related parties, which will include all debt where Brookfield or other affiliates are the ultimate counterparty, regardless of whether a debt instrument is publicly listed. Additionally, all accrued interest on related party debt will be reflected within the Due to related parties line item rather than within Accounts payable and other, as previously reported.

The following table provides a reconciliation of the resulting reclassifications directly related to the change in accounting policy discussed above to the Partnerships consolidated statements of financial position:


	As at		As at
	December 31, 2020		December 31, 2020

Total non-current liabilities	3,003,526	—	3,003,526

(1)The Partnership has elected to restate its December 31, 2020 consolidated statement of financial position to retrospectively show the change in accounting policy adopted during the three months ended September 30, 2021. The impact of the accounting policy change as at December 31, 2020 is a reclassification of the Partnerships $411.3 million outstanding senior unsecured bonds held by Brookfield from Borrowings (non-current) to Due to related parties (non-current) and $16.1 million in accrued interest on said bonds from Accounts payable and other (current) to Due to related parties (current).

(6)See Note 2c iv) for additional information.

The fair value of all financial assets and liabilities as at September 30, 2021 approximated their carrying values, with the exception of the borrowings, where fair value which was determined using Level 1 and Level 2 inputs and resulted in a fair value of $2,534 million (December 31, 2020 Restated: $2,753 million) compared to a carrying value of $2,574 million (December 31, 2020 Restated: $2,760 million). The fair value of the Partnership’s borrowings is either based on quoted market prices or estimated using discounted cash flow analysis based on rates currently available for debt with similar terms and remaining maturities and the current credit worthiness of the Partnership.

In addition, within the December 31, 2020 Restated Due to related parties (current and non-current) shown above, $411.3 million of the outstanding senior unsecured bonds held by Brookfield were fair valued using Level 1 and Level 2 inputs and resulted in a fair value of $351.4 million.

Fair value hierarchical levels - financial instruments

For assets and liabilities that are recognized at fair value on a recurring basis, the Partnership determines whether transfers have occurred between levels in the hierarchy by re-assessing categorization (based on the lowest level input that is significant to the fair value measurement as a whole) at the end of each reporting period. There were no transfers between levels during the three and nine months ended September 30, 2021, nor during the year ended December 31, 2020. Additionally, there were no changes in the Partnership’s valuation processes, valuation techniques, and types of inputs used in the fair value measurements during the three and nine months ended September 30, 2021. The following table provides the fair value measurement hierarchy of the Partnership's financial assets and

(all tabular amounts stated in thousands of U.S. Dollars, except unit and per unit data)

The liability for the finance leases accrues interest at a variable rate of LIBOR plus a margin of 2.85%. As at September 30, 2021, the Partnership was in compliance with all covenant requirements of its finance leases.

Derivative Financial Instruments

The Partnership’s activities expose it to a variety of financial risks, including liquidity risk, interest rate risk, foreign currency risk and credit risk. The Partnership selectively uses derivative financial instruments principally to manage certain of these risks.

The aggregate amount of the Partnership's derivative financial instrument positions is as follows:

Interest Rate Risk

Interest rate risk is the risk that the fair value or future cash flows of a financial instrument will fluctuate because of changes in market interest rates. The Partnership is exposed to the impact of interest rate changes, primarily through its floating-rate borrowings that require it to make interest payments based on LIBOR. Significant increases in interest rates could adversely affect operating margins, results of operations and the Partnership's ability to service its debt. The Partnership uses interest rate swaps to reduce its exposure to market risk from changes in interest rates. The principal objective of these contracts is to minimize the risks and costs associated with the Partnership's floating-rate debt.

The Partnership enters into interest rate swaps, which exchange a receipt of floating interest for a payment of fixed interest, to reduce the Partnership’s exposure to interest rate variability on its outstanding floating-rate debt. The Partnership has not designated, for accounting purposes, any of its interest rate swaps as hedges of variable rate debt. Certain of the Partnership's interest rate swaps are secured by vessels.

In February 2021, the Partnership terminated two and amended two of its interest rate swap agreements, which as at December 31, 2020, had a total notional amount of $600.3 million and a total fair value liability of $147.5 million. These interest rate swaps included early termination provisions, which if exercised, would have terminated these interest rate swaps in February 2021. Following the terminations and amendments, the total notional amount relating to the two remaining interest rate swap agreements was reduced to $132.0 million in April 2021. These agreements include mandatory termination provisions which terminate these interest rate swaps February 2022.

In March 2021, the Partnership terminated one of its interest rate swaps, which as at December 31, 2020, had a notional value of $90.4 million and a fair value liability of $37.1 million. This interest rate swap included an early termination provision, which was exercised in March 2021.

As at September 30, 2021, the Partnership and its consolidated subsidiaries were committed to the following interest rate swap agreements:

15.Segment Information

For the three and nine months ended September 30, 2021 and 2020, the Partnership's operations were organized into five operating segments: FPSO, Shuttle Tanker, FSO, UMS and Towage.

These operating segments are regularly reviewed by the Partnership's Chief Operating Decision Maker (or CODM) for the purpose of allocating resources to the segment and to assess its performance. The key measure used by the CODM in assessing performance and in making resource allocation decisions is Adjusted EBITDA, which is calculated as net income (loss) before interest expense, interest income, income tax expense, and depreciation and amortization, adjusted to exclude certain items whose timing or amount cannot be reasonably estimated in advance or that are not considered representative of core operating performance. Such adjustments include impairment expenses, gain (loss) on dispositions, net, unrealized gain (loss) on derivative instruments, foreign currency exchange gain (loss) and certain other income or expenses. Adjusted EBITDA also excludes: realized gain or loss on interest rate swaps, as management, in assessing the Partnership's performance, views these gains or losses as an element of interest expense; realized gain or loss on derivative instruments resulting from amendments or terminations of the underlying instruments; realized gain or loss on foreign currency forward contracts; and equity-accounted income (loss). Adjusted EBITDA also includes the Partnership's proportionate share of Adjusted EBITDA from its equity-accounted investments and excludes the non-controlling interests' proportionate share of Adjusted EBITDA. The Partnership does not have control over the operations of, nor does it have any legal claim to the revenues and expenses of its equity-accounted investments. Consequently, the cash flow generated by the Partnership’s equity-accounted investments may not be available for use by the Partnership in the period that such cash flows are generated.

PART I – FINANCIAL INFORMATION

ITEM 2 - MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS

Overview of Our Business

We are a leading global energy infrastructure services provider primarily focused on the ownership and operation of critical infrastructure assets in the offshore oil regions of the North Sea, Brazil and the East Coast of Canada. We currently operate floating production, storage and off-loading (or FPSO) units, shuttle tankers, floating storage and off-take (or FSO) units, a unit for maintenance and safety (or UMS) and long-distance towage and offshore installation (or towage) vessels and our operations are organized into these five corresponding operating segments. As at September 30, 2021, our fleet was as follows:


	Number of Vessels
	Owned Vessels		Chartered-in Vessels	Committed Newbuildings		Total
FPSO Segment	7	(i)	—	—		7
Shuttle Tanker Segment	23	(ii)	1	1	(iii)	25
FSO Segment	3		—	—		3
UMS Segment	1		—	—		1
Towage Segment	10		—	—		10
Total	44		1	1		46

(i)Includes two FPSO units, the Cidade de Itajai and Pioneiro de Libra, in which our ownership interest is 50 percent and also includes two units which are currently in lay-up.

(ii)Includes two shuttle tankers in which our ownership interest is 50 percent. All of our operating shuttle tankers provide transportation services to energy companies predominately in the North Sea, Brazil and the East Coast of Canada. Our shuttle tankers occasionally service the conventional spot tanker market and we occasionally charter-in shuttle tankers in the spot market.

(iii)Includes one DP2 shuttle tanker newbuilding scheduled for delivery in early-2022, which will operate under an existing contract off the East Coast of Canada.

Global crude oil and gas prices have largely recovered from the uncertainty regarding demand created by the COVID-19 pandemic. However, as the timing of the ongoing global immunization effort, including the effectiveness of the vaccines, and the severity of outbreaks of variants of the virus are still highly uncertain and cannot be predicted, the long-term impact of the pandemic on our business, financial condition and operating results cannot be determined. Our business involves the ownership and operation of critical infrastructure assets in offshore oil regions and any significant decrease in demand for crude oil could adversely affect the demand for our vessels and the types of services we offer. Additionally, a continuation of the pandemic may result in reduced cash flow and financial condition, including potential liquidity constraints and potential reduced access to capital as a result of any credit tightening generally or due to declines in global financial markets. Our business model is to employ our vessels on fixed-rate contracts with oil companies, typically with terms between three and ten years, and therefore we do not expect any significant near-term impact on our liquidity, except for a decline in activity in the spot markets serviced mainly by our towage vessels. Potential effects of the pandemic include, among others, force majeure claims relating to existing contracts, increased counterparty risk and/or default, fewer contract extension opportunities, and in the worst case, contract terminations resulting from relevant early field abandonment programs. As at September 30, 2021, we have not experienced any material business disruptions or a direct material financial impact as a result of the pandemic and we are actively pursuing additional steps to preserve liquidity and our financial flexibility. Our operational focus over the short-term is to focus on extending contracts and the redeployment of our assets that are scheduled to come off charter over the next few years.

Measures to improve our maturity profile and enhance liquidity

On August 27, 2021, we entered into an agreement with Brookfield Business Partners L.P., and certain of its affiliates and institutional partners (collectively, "Brookfield") to exchange at par $699.3 million of indebtedness in Altera GP with interest rates ranging from 5.0% to 11.5% and with maturities ranging from 2022 to 2024 (including $411 million of Altera’s 8.5% Senior Notes due 2023 (the "Notes") held by Brookfield) for 11.5% Senior Secured PIK Notes due 2026.

In July 2021, we suspended the payment of quarterly cash distributions on our outstanding 7.25% Series A Cumulative Redeemable Preferred Units (the “Series A Units”), 8.50% Series B Cumulative Redeemable Preferred Units (the “Series B Units”) and 8.875% Series E Fixed-to-Floating Rate Cumulative Redeemable Perpetual Preferred Units (the “Series E Units” and, together with the Series A Units and Series B Units, the “Preferred Units”) commencing with the distributions payable with respect to the period of May 15, 2021 to August 14, 2021. All distributions on the Preferred Units will continue to accrue and must be paid in full before distributions to Class A and Class B common unitholders can be

made. No distributions on the Preferred Units will be permitted without noteholder consent while the new 11.5% PIK notes due 2026 issued in the exchange transactions described above remain outstanding.

Sale of Vessels

In August 2021, we delivered the 1999-built Navion Anglia shuttle tanker to its buyer for responsible recycling and received total proceeds of $6 million and recorded a gain on sale of the vessel of $1 million during the third quarter of 2021.

Accounting policy update

In August 2021, we revised our accounting policy to classify all debt held by Brookfield as Due to related parties. Previously the accounting policy elected by us reflected our long-term debt within two line items, Borrowings and Due to related parties. We have reflected this change retrospectively by restating our comparative consolidated statement of financial position. Please refer to Item 1 – Financial Statements: Note 2c iv) - Related Party Borrowings Reclassification for additional information.
