NOTES TO THE UNAUDITED INTERIM CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

As at June 30, 2021 and December 31, 2020 and for the three and six months ended June 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 July 29, 2021.

b.Going concern

As at June 30, 2021, the Partnership had a working capital deficit of $307.2 million primarily relating to scheduled maturities and repayments of $336.0 million of outstanding borrowings during the 12 months ending June 30, 2022, which amounts were classified as current as at June 30, 2021. The Partnership also anticipates making payments related to commitments to fund a vessel under construction during the remainder of 2021 through 2022 of $98.9 million; however, the Partnership has secured long-term financing related to this vessel.

The working capital deficit of $307.2 million as at June 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 $82.5 million mainly relating to amounts held in escrow for a shuttle tanker newbuilding yard installment payment as at December 31, 2020 and a decrease in accounts receivable and other of $24.5 million, partially offset by a decrease in total current liabilities primarily relating to the termination or amendment of certain interest rate swaps during the three months ended June 30, 2021.

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. On July 29, 2021, the Partnership announced various measures it is pursuing to improve its debt maturity profile and enhance its liquidity and financial flexibility. See Note 17 for additional information about these measures. Other potential sources of financing that the Partnership is actively pursuing, or may consider pursuing, during the one-year period to June 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

(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 June 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 six months ended June 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 June 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	385,421	2.62	Expected to amend fallback clauses prior to cessation of publication of LIBOR.
Term Loans	1,163,268	4.17
Public Bonds	200,000	3.30
Total	1,748,689	3.73

Interest rate benchmark transition for derivatives

As at June 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.

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 six months ended June 30, 2021. The Partnership will continue to monitor the COVID-19 situation and review its critical estimates and judgements as circumstances evolve.

(2)Includes investments in finance leases.

(3)Includes accounts payable and lease liabilities. Refer to Note 9 below.

(4)Includes derivative instruments, obligations relating to finance leases and other financial liabilities. Refer to Note 10 below.

(5)Fair value through profit or loss (or FVTPL).

The fair value of all financial assets and liabilities as at June 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 $3,038 million (December 31, 2020: $3,104 million) compared to a carrying value of $3,056 million (December 31, 2020: $3,171 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.

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 six months ended June 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 six months ended June 30, 2021. The following table provides the fair value measurement hierarchy of the Partnership's financial assets and liabilities measured at fair

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:

	June 30, 2021		December 31, 2020
	Financial Asset	Financial Liability	Financial Asset	Financial Liability
	$	$	$	$

Total current	1,059	33,479	6,497	189,647
Total non-current	—	1,474	—	13,950

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

	Interest Rate Index	Notional Amount $	Fair Value / Carrying Amount of Asset (Liability)(1) $	Weighted- Average Remaining Term (years)	Fixed Interest Rate (%)(2)
U.S. Dollar-denominated interest rate swaps (3)	LIBOR	152,903	(9,406)	1.05	2.6	%

		579,022	(34,721)

(1)Excludes accrued interest of $1.9 million.

(2)Excludes the margins the Partnership pays on its variable-rate debt, which as at June 30, 2021, ranged between 1.10% and 6.50%.

(3)Notional amount remains constant over the term of the swap, unless the swap is partially terminated.

(4)Principal amount reduces quarterly or semi-annually.

The Partnership is a party to the following transactions with related parties:

a)As at June 30, 2021, the Partnership had an undrawn balance of $nil (December 31, 2020 - $nil) relating to an unsecured revolving credit facility provided by Brookfield, which provides for borrowings of up to $225.0 million and matures on October 31, 2024. The interest payments on the facility are based on LIBOR plus a margin of 5.00%. The agreement provides the Partnership the option to defer interest payments of up to $25.0 million until maturity. As at June 30, 2021, the Partnership has deferred a total of $9.9 million of interest payments. Any outstanding principal balances are due on the maturity date. The Partnership previously determined that as the interest rate under the facility was deemed to be at below market terms, Brookfield was acting in its capacity as an equity owner, and the Partnership recorded a $37.1 million decrease in the carrying value of the facility, which was classified as an equity contribution in the Partnership's unaudited interim condensed consolidated statements of changes in equity during the year ended December 31, 2020. As at June 30, 2021, the Partnership was in compliance with the covenant requirements of this revolving credit facility.

b)During the six months ended June 30, 2021, the Partnership entered into an unsecured revolving credit facility provided by Brookfield, which provides for borrowings of up to $30 million and as at June 30, 2021, had an undrawn balance of $nil. The interest payments on the facility are based on LIBOR plus a margin of 5.00% and the facility matures in February 2022. Any outstanding principal balances are due on the maturity date. During the six months ended June 30, 2021, the Partnership determined that the interest rate under the facility was deemed to be at below market terms and therefore, Brookfield was acting in its capacity as an equity owner. The Partnership recorded a $1.3 million decrease in the carrying value of the facility, which was classified as an equity contribution in the Partnership's unaudited interim condensed consolidated statements of changes in equity during the six months ended June 30, 2021. As at June 30, 2021, the Partnership was in compliance with the covenant requirements of this revolving credit facility.

c)During the six months ended June 30, 2021, a subsidiary of the Partnership entered into an unsecured revolving credit facility provided by Brookfield, which provides for borrowings of up to $70 million and as at June 30, 2021, had an undrawn balance of $nil. The interest payments on the facility are based on LIBOR plus a margin of 5.00% and the facility matures in February 2022. Any outstanding principal balances are due on the maturity date. During the six months ended June 30, 2021, the Partnership determined that the interest rate under the facility was deemed to be at below market terms and therefore, Brookfield was acting in its capacity as

15.Segment Information

For the three and six months ended June 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.

Adjusted EBITDA is also used by external users of the Partnership's unaudited interim condensed consolidated financial statements, such as investors and the Partnership’s controlling unitholder.

The following tables include the results for the Partnership’s reportable segments for the periods presented in these unaudited consolidated financial statements:

16.Distributions

The distributions paid on the preferred units for the three and six months ended June 30, 2021 were $7.9 million and $15.8 million, respectively (three and six months ended June 30, 2020 - $8.0 million and $16.1 million, respectively).

17.Subsequent Events

On July 29, 2021, the Partnership announced a series of measures to improve the Partnership’s maturity profile and enhance its liquidity and financial flexibility. As part of these measures, the Partnership has taken the following actions:

•Entered into an agreement with Brookfield Business Partners L.P., and certain of its affiliates and institutional partners (collectively, "Brookfield") to exchange at par approximately $700 million of indebtedness in Altera GP 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 and commenced an exchange transaction relating to the $276 million of Notes held by non-Brookfield parties.

•Suspended the payment of quarterly cash distributions on the Partnership’s 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 PIK notes issued in the exchange transactions described above remain outstanding.

The Partnership expects to achieve significant annual cashflow savings as a result of the agreement with Brookfield and suspension of quarterly distributions on the Preferred Units. In addition, there is potential for further annual cashflow savings depending on the outcome of the exchange of the Notes held by non-Brookfield parties. If all of the Notes are exchanged in the exchange transactions, which remain subject to the satisfaction of certain conditions, these measures will also extend maturities currently ranging from 2022 to 2024 on approximately $970 million of indebtedness to 2026, including indebtedness held by Brookfield.

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 June 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	24	(ii)	1	1	(iii)	26
FSO Segment	3		—	—		3
UMS Segment	1		—	—		1
Towage Segment	10		—	—		10
Total	45		1	1		47

(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 June 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.

Significant Developments

Delivery of Shuttle Tanker Newbuildings

The fifth and sixth LNG-fueled E-Shuttles, the Altera Wave and Altera Wind, commenced operations in the second quarter. The Altera Thule is expected to be delivered early in 2022 and to operate off the East Coast of Canada.

Measures to improve our maturity profile and enhance liquidity

On July 29, 2021, we announced a series of measures to improve our maturity profile and enhance our liquidity and financial flexibility. As part of these measures, we have taken the following actions:

•Entered into an agreement with Brookfield Business Partners L.P., and certain of its affiliates and institutional partners (collectively, "Brookfield") to exchange at par approximately $700 million of indebtedness in Altera GP 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 and commenced an exchange transaction relating to the $276 million of Notes held by non-Brookfield parties.

•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

Page 24 of 42

Class B common unitholders can be made. No distributions on the Preferred Units will be permitted without noteholder consent while the new PIK notes issued in the exchange transactions described above remain outstanding.

We expect to achieve in excess of $80 million in annual cashflow savings as a result of the agreement with Brookfield and suspension of quarterly distributions on the Preferred Units. In addition, there is potential for further annual cashflow savings depending on the outcome of the exchange of the Notes held by non-Brookfield parties. If all of the Notes are exchanged in the exchange transactions, which remain subject to the satisfaction of certain conditions, these measures will also extend maturities currently ranging from 2022 to 2024 on approximately $970 million of indebtedness to 2026, including indebtedness held by Brookfield.

Sale of Vessels

In April 2021, we delivered the 1987-built Dampier Spirit FSO to its buyer for responsible recycling and received total proceeds of $4 million and recorded a gain on sale of the vessel of $4 million during the second quarter of 2021.

In May 2021, we delivered the 2001-built Navion Oslo shuttle tanker to its buyer for responsible recycling and received total proceeds of $3 million, which was the approximate carrying value of the vessel.

In June 2021, we delivered the 1999-built Navion Oceania shuttle tanker to its buyer for continued operations and received total proceeds of $11 million and recorded a gain on sale of the vessel of $3 million during the second quarter of 2021.

In June 2021, we delivered the 2001-built Stena Natalita shuttle tanker to its buyer for continued operations and received total proceeds of $8 million, which was the approximate carrying value of the vessel.

Three Months Ended June 30, 2021 compared with the Three Months Ended June 30, 2020

Revenues

Revenues decreased to $267 million, from $304 million, for the three months ended June 30, 2021, compared to the same period last year, primarily due to a decrease in our FPSO, shuttle tanker and FSO segments, partially offset by an increase in revenue in our towage segment, as described below:

FPSO Segment

Revenues decreased in our FPSO segment to $111 million, from $131 million, for the three months ended June 30, 2021, compared to the same period last year, primarily due to:

•a decrease of $12 million due to the Voyageur Spirit FPSO unit ceasing operations under its contract in June 2020;

•a decrease of $7 million due to the Piranema Spirit FPSO unit completing its contract in April 2021;

•a decrease of $7 million due to a reduction of management fees as management of the Banff FPSO ended November 2020; and

•a decrease of $2 million due to direct operating costs relating to our joint ventures (offset by an decrease in direct operating costs of $2 million as noted below);

partially offset by

•an increase of $5 million due to demobilization activities on the Foinaven FPSO unit during the second quarter of 2021; and

•an increase of $4 million due to Rosebank post concept studies.

Shuttle Tanker Segment

Revenues decreased in our shuttle tanker segment to $125 million, from $138 million, for the three months ended June 30, 2021, compared to the same period last year, primarily due to:

•a decrease of $9 million due to lower rates and less operating days in the conventional tanker market in which our shuttle tankers occasionally operate;

•a decrease of $8 million due to the redelivery to us of the Navion Anglia, Navion Bergen and Navion Gothenburg shuttle tankers during 2020; and

Page 26 of 42

•a decrease of $5 million due to termination of the Foinaven CoA contract in May 2021;

partially offset by

•an increase of $3 million due to higher average CoA rates;

•an increase of $3 million due to reduced off hire days; and

•an increase of $3 million due to an increase in operating days under a master agreement with Equinor ASA.

FSO Segment

Revenues decreased in our FSO segment to $19 million, from $28 million, for the three months ended June 30, 2021, compared to the same period last year, primarily due to:

•a decrease of $11 million due to lower charter rates following a contract extension for the Randgrid FSO unit in June 2020; and

•a decrease of $1 million due to the absence of contribution from the Dampier Spirit FSO and Apollo Spirit FSO, as their contracts ended in the third quarter of 2020;

Shuttle Tanker Segment

Impairment expense, net in our shuttle tanker segment was $2 million for the three months ended June 30, 2020, due to a $2 million impairment of the Navion Bergen due to the expected sale of the vessel.

Gain (Loss) on Dispositions, Net

Gain (loss) on dispositions, net was $9 million for the three months ended June 30, 2021, compared to $(1) million for the same period last year, primarily due to gains recorded in our FSO and shuttle tanker segments for the three months ended June 30, 2021. During the three months ended June 30, 2021, we sold four vessels and recognized gains on dispositions of $4 million relating to the Dampier Spirit FSO and $3 million relating to the Navion Oceania shuttle tanker. We recorded an additional gain on disposition of $3 million relating to the Apollo Spirit FSO sold in December 2020, after the official recycling of the vessel was completed based on a recycling rate agreed upon with the buyer as per terms of the contract. The remaining two vessels were sold at their approximate carrying values. During the three months ended June 30, 2020 we sold the HiLoad DP unit and recognized a loss on disposition of $(1) million.

Realized and Unrealized Gain (Loss) on Derivative Instruments

Net realized and unrealized gain (loss) on derivative instruments was $(2) million for the three months ended June 30, 2021, compared to $(15) million for the same period last year and were comprised of the following:

	Three Months Ended June 30,

During the three months ended June 30, 2020, we recognized realized losses of $19 million on our interest rate swaps as a result of the termination or amendment of certain of our interest rate swaps. Realized losses on our interest rate swaps for the three months ended June 30,

Page 28 of 42

2021, were otherwise consistent with the same period last year. We also recognized unrealized gains on interest rate swaps of $3 million during the three months ended June 30, 2021, compared to unrealized gain of $5 million during the same period last year.

During the three months ended June 30, 2021 and 2020, we were committed to foreign currency forward contracts to hedge portions of our forecasted expenditures in Norwegian Krone (or NOK) and Euros, which resulted in realized gains (losses) of $2 million and $(2) million during the three months ended June 30, 2021 and 2020, respectively. We also recognized unrealized losses on our foreign currency forward contracts of $2 million during the three months ended June 30, 2021, compared to unrealized gains of $8 million for the same period last year, mainly due to an unfavorable forward spread as at June 30, 2021, compared to a favorable forward spread as at June 30, 2020.

Foreign Currency Exchange Gain (Loss)

Foreign currency exchange gain (loss) was $nil for the three months ended June 30, 2021, compared to $(1) million for the same period last year. Our foreign currency exchange gain (loss) is due primarily to the relevant period-end revaluations of NOK-denominated monetary assets and liabilities for financial reporting purposes. Gains on NOK-denominated net monetary liabilities reflect a stronger U.S. Dollar against the NOK on the date of revaluation or settlement compared to the rate in effect at the beginning of the period. Losses on NOK-denominated net monetary liabilities reflect a weaker U.S. Dollar against the NOK on the date of revaluation or settlement compared to the rate in effect at the beginning of the period.

Other Income (Expenses), Net

Other income (expenses), net was $(2) million for the three months ended June 30, 2021, compared to $(4) million for the same period last year, primarily due to less restructuring costs.

Income Tax (Expense) Recovery

Income tax (expense) recovery was $(1) million for the three months ended June 30, 2021, compared to $nil for the same period last year.

Adjusted EBITDA

Adjusted EBITDA decreased to $110 million for the three months ended June 30, 2021, compared to $153 million for the same period last year. This decrease was primarily due to a decrease in revenue and an increase in direct costs in our shuttle tanker segment and a decrease in revenue in our FPSO and FSO segments, as described above.

Income Tax (Expense) Recovery

Income tax (expense) recovery was $(2) million for the six months ended June 30, 2021, compared to $(4) million for the same period last year. The decrease in income tax expense was primarily due to a deferred expense recorded during the six months ended June 30, 2020, due to a decrease in the expected use of tax losses in Norway.

Adjusted EBITDA

Adjusted EBITDA decreased to $230 million for the six months ended June 30, 2021, compared to $317 million for the same period last year. This decrease was primarily due to a decrease in revenue in our FPSO, shuttle tanker, and FSO segments, and an increase in direct costs in our FPSO and towage segments, partially offset by increased revenue in the towage segment and lower cost in the shuttle tanker segment as described above.

Non-IFRS Financial Measures

To supplement the unaudited interim condensed consolidated financial statements, we use Adjusted EBITDA, which is a non-IFRS financial measure, as a measure of our performance. Adjusted EBITDA represents net income (loss) before interest expense, interest income, income tax (expense) recovery, and depreciation and amortization, and is adjusted to exclude certain items whose timing or amount cannot be reasonably estimated in advance or that are not considered representative of our 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 we, in assessing our performance, view 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 our proportionate share of Adjusted EBITDA from our equity-accounted investments and excludes the non-controlling interests' proportionate share of Adjusted EBITDA. We do not have control over the operations of, nor do we have any legal claim to the revenues and expenses of our equity-accounted investments. Consequently, the cash flow generated by our equity-accounted investments may not be available for use by us in the period that such cash flows are generated.

Adjusted EBITDA is intended to provide additional information and should not be considered as the sole measure of our performance or as a substitute for net income (loss) or other measures of performance prepared in accordance with IFRS. In addition, this measure does not have a standardized meaning and may not be comparable to similar measures presented by other companies. This non-IFRS measure is used by our management, and we believe that this supplementary metric assists investors and other users of our financial reports in comparing our financial and operating performance across reporting periods and with other companies.

The following table reconciles Adjusted EBITDA to net income (loss) for the three and six months ended June 30, 2021 and 2020:

Liquidity and Capital Resources

Liquidity is managed primarily through cash flows from operations, use of credit facilities and refinancing existing debt. We aim to maintain sufficient financial liquidity to meet our ongoing operating requirements.

The following table presents our liquidity as at June 30, 2021 and December 31, 2020:

	June 30, 2021	December 31, 2020
	$	$
Cash and cash equivalents	241,132	235,734
Total liquidity (1)	241,132	235,734
Working capital surplus (deficit)	(307,166)	(230,494)

(1)Defined as cash, cash equivalents and undrawn revolving credit facilities

The increase in the working capital deficit was primarily due to a decrease in financial assets of $83 million mainly relating to amounts held in escrow for a shuttle tanker newbuilding yard installment payment as at December 31, 2020 and a decrease in accounts receivable and other of $25 million, partially offset by a decrease in total current liabilities primarily relating to the termination or amendment of certain interest rate swaps during the six months ended June 30, 2021.

Page 36 of 42

Our primary short-term liquidity needs are to pay existing committed capital expenditures, to make scheduled repayments of debt and related interest rate swaps, to pay debt service costs, to pay operating expenses and dry-docking expenditures, to fund general working capital requirements, to settle claims and potential claims against us and to manage our working capital deficit.

Our long-term liquidity needs are to repay or refinance scheduled debt obligations and pursue additional growth projects. Please see “– Significant Developments – Measures to improve our maturity profile and enhance liquidity” for information about recent initiatives we expect will increase our cash flow.

We have no off-balance sheet arrangements that have or are reasonably likely to have, a current or future material effect on our financial condition, changes in financial condition, revenues or expenses, results of operations, liquidity, capital expenditures or capital resources.

The following table sets forth our contractual obligations for the periods indicated as at June 30, 2021:

(1)Our interest-bearing obligations include bonds, commercial bank debt, unsecured revolving credit facilities provided by Brookfield and obligations related to finance leases. Please refer to Item 1 – Financial Statements: Note 11 – Borrowings, Item 1 – Financial Statements: Note 12 – Related Party Transactions and Item 1 – Financial Statements: Note 10 – Other Financial Liabilities for terms upon which future interest payments are determined.

(2)Consists of the financial liability relating to our foreign currency forward contracts and our interest rate swaps. Please refer to Item 1 – Financial Statements: Note 10 – Other Financial Liabilities for a summary of the terms of our derivative instruments which economically hedge certain of our floating rate interest-bearing obligations.

(3)Consists of the undiscounted cash requirements to settle our lease obligations relating to our office leases and in-chartered vessels.

(4)Consists of the estimated remaining payments for the acquisition of one shuttle tanker newbuilding. Please refer to Item 1 – Financial Statements: Note 8 – Advances on Newbuilding Contracts. We have secured $84.5 million of undrawn borrowings relating to this shuttle tanker newbuilding commitment.

Primarily as a result of the working capital deficit and committed capital expenditures, during the one-year period from June 30, 2021, we will need to obtain additional sources of financing, in addition to amounts generated from operations, to meet our obligations and commitments and the minimum liquidity requirements under our financial covenants in our credit facilities. On July 29, 2021, the Partnership announced various measures it is pursuing to improve its debt maturity profile and enhance its liquidity and financial flexibility, Refer to Item 1 – Financial Statements: Note 17 - Subsequent events for additional information. Other potential sources of financing that we are actively pursuing, or may consider pursuing, during the one-year period from June 30, 2021, 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 our business interests and/or capital raises. Additional potential sources of amounts generated from operations include the extensions and redeployment of existing assets. Based on our liquidity at the date of these unaudited interim condensed consolidated financial statements, the liquidity we expect to generate from operations over the following year, and by incorporating our plans to raise additional liquidity that we consider probable of completion, we expect that we will have sufficient liquidity to meet our existing liquidity needs for at least the one-year period from June 30, 2021. Refer to Item 1 – Financial Statements: Note 2b - Going Concern for additional information.

As at June 30, 2021, we had total borrowings outstanding of $3,091 million compared to $3,211 million as at December 31, 2020 and as at June 30, 2021, we were in compliance with all covenants relating to our consolidated borrowings. Our borrowings consist of the following:

Cash Flows

The following table summarizes our sources and uses of cash for the periods presented:

(in thousands of U.S. Dollars)	Six months ended June 30,
	2021	2020
Net operating cash flow	60,906	180,274
Net financing cash flow	18,970	19,481
Net investing cash flow	(74,847)	(154,053)

Operating Cash Flows

Net cash flow from operating activities decreased to $61 million for the six months ended June 30, 2021, compared to $180 million for the same period last year, primarily due to an increase to $157 million in realized losses on interest rate swaps during the six months ended June 30, 2021, compared to $32 million during the same period last year, which was a result of the termination or partial termination of certain interest rate swaps during the six months ended June 30, 2021. This was partially offset by changes in non-cash working capital items which provided for a contribution of $79 million for the six months ended June 30, 2021, compared to $9 million for the six months ended June 30, 2020. The increase in non-cash working capital items for the six months ended June 30, 2021, compared to the same period last year is primarily due to the timing of payments received from customers and made to vendors.

Net cash flow from operating activities also decreased for the six months ended June 30, 2021, compared to the same period last year, due to a decrease in revenues and an increase in direct operating costs. Refer to "Results of Operations" above.

Financing Cash Flows

We use our revolving credit facilities to finance capital expenditures and for general corporate purposes. Occasionally, we will do this until longer-term financing is obtained, at which time we typically use all or a portion of the proceeds from the longer-term financings to prepay outstanding amounts under the revolving credit facilities. Our proceeds from borrowings, net of financing costs, were $75 million for the six months ended June 30, 2021, and $72 million for the same period last year.

We actively manage the maturity profile of our outstanding financing arrangements. Our scheduled repayments of our borrowings were $196 million for the six months ended June 30, 2021, compared to $160 million for the same period last year. The increase in repayments is mainly due to the refinancing of one existing debt facility during the six months ended June 30, 2021.

Our proceeds from borrowings, net of financing costs and scheduled repayments, related to the sale and leaseback of vessels, were $71 million and $36 million for the six months ended June 30, 2021 and 2020, respectively. The gross proceeds were used to fund installment payments on certain of the shuttle tanker newbuildings.

During the six month ended June 30, 2021, we entered into two additional unsecured credit facilities with Brookfield. As at June 30, 2021, the total of three unsecured revolving credit facilities provided for total borrowings of up to $325 million. During the six months ended June 30, 2021, we drew down $130 million and prepaid $30 million related to these credit facilities. During the six months ended June 30, 2020, we drew down $105 million related to one existing facility.

Lease payments on our vessel in-charter leases and office leases were $7 million and $11 million for the six months ended June 30, 2021 and 2020, respectively.

Cash distributions paid to our preferred unitholders were $16 million for the six months ended June 30, 2021 and 2020. Refer to Item 1 – Financial Statements: Note 17 - Subsequent events for additional information.

Page 38 of 42

Investing Cash Flows

During the six months ended June 30, 2021, net cash flow used for investing activities was $75 million, primarily related to $169 million for additions to vessels and equipment, including installment payments for the delivery of two shuttle tanker newbuildings, partially offset by a $68 million decrease in restricted cash, primarily related to a $74 million reduction to amounts held in escrow for the final installment payment for one of the above mentioned shuttle tanker newbuildings, partially offset by cash sweep requirements under a previously amended loan agreement, and proceeds of $29 million from the sales of the Navion Oceania, Navion Oslo and Stena Natalita shuttle tankers and the Dampier Spirit and Apollo Spirit FSO units.

During the six months ended June 30, 2020, net cash flow used for investing activities was $154 million, primarily related to $239 million for additions to vessels and equipment, including installment payments on the shuttle tanker newbuildings, partially offset by an $66 million decrease in restricted cash, primarily related to a $89 million reduction to amounts held in escrow for the final installment payment for one shuttle tanker newbuilding, proceeds of $15 million from the sales of the Navion Hispania and Stena Sirita shuttle tankers and the Petrojarl Cidade de Rio das Ostras FPSO unit and $6 million of cash acquired during the acquisition of one company.

Critical Accounting Estimates

The preparation of financial statements requires us to make critical judgments, estimates and assumptions in the application of our accounting policies that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses that are not readily apparent from other sources, during the reporting period. These estimates and associated assumptions are based on historical experience and other factors that are considered to be relevant. Our management reviews our accounting policies, critical judgments, estimates and assumptions on a regular basis. However, because future events and their effects cannot be determined with certainty, actual results could differ from our assumptions and estimates and such differences could be material. Revisions to accounting estimates are recognized in the period in which the estimate is revised if the revision affects only that period, or in the period of the revision and future periods if the revision affects both current and future periods.

For further information on our material accounting policies, critical accounting judgments and estimates see Part I, Item 18 - Financial Statements: Note 2v. - Critical accounting judgments and key sources of estimation uncertainty and Part I, Item 5B. Liquidity and Capital Resources - Critical Accounting Estimates in our Annual Report on Form 20-F for the year ended December 31, 2020.

ITEM 3 - QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

Our direct exposure to market risk results from fluctuations in interest rates foreign currency exchange rates and commodity prices. There have been no material changes to our market risks as disclosed in our Annual Report on Form 20-F for the year ended December 31, 2020.

ITEM 4 - CONTROLS AND PROCEDURES

Changes in Internal Control Over Financial Reporting

There have been no changes in our internal control over financial reporting (as defined in Rules 13a-15(f) or 15d-15(f) under the U.S. Securities and Exchange Act of 1934, as amended) that occurred during the six months ended June 30, 2021 that have materially affected, or are reasonably likely to materially affect, the Partnership’s internal control over financial reporting.

Remediation

As previously described in Part II, Item 15 of our Annual Report on Form 20-F for the year ended December 31, 2020, we began implementing a remediation plan to address a material weakness due to the existence of control deficiencies related to user access management within the IT environment. The weakness will not be considered remediated, until the applicable controls operate for a sufficient period of time and management has concluded, through testing, that these controls are operating effectively. We expect that the remediation of this material weakness will be completed during the year ended December 31, 2021.

ALTERA INFRASTRUCTURE L.P. AND SUBSIDIARIES

June 30, 2021

PART II – OTHER INFORMATION

Item 1 – Legal Proceedings

Occasionally we have been, and expect to continue to be, subject to legal proceedings and claims in the ordinary course of our business, principally personal injury and property casualty claims. These claims, even if lacking merit, could result in the expenditure of significant financial and managerial resources.

Please read Part III, Item 18. – Financial Statements: Note 17 – Provisions and Contingencies in our Annual Report on Form 20-F for the year ended December 31, 2020 for a description of certain claims made against us.

Item 1A – Risk Factors

In addition to the other information set forth in this Report on Form 6-K, you should carefully consider the risk factors discussed in Part I, Item 3 - Key Information - D. Risk Factors in our Annual Report on Form 20-F for the year ended December 31, 2020, and in Part II, Item 1 - Risk Factors in our Report on Form 6-K furnished on May 5, 2021, which could materially affect our business, financial condition or results of operations and the price and value of our securities.

We have limited current liquidity and any deterioration in business conditions could further significantly reduce our liquidity.

As at June 30, 2021, we had total liquidity of $241.1 million and a working capital deficit of $307.2 million. Our limited availability under existing credit facilities and our current working capital deficit could limit our ability to meet our financial obligations and growth prospects. We expect to manage our working capital deficit primarily with amounts generated from operations, including extensions and redeployments of existing assets, and additional potential sources of financing, including entering into new debt facilities, borrowing additional amounts under existing facilities, the refinancing or extension of certain borrowings and interest rate swaps, selling certain assets, seeking joint venture partners for the Partnerships business interests and/or capital raises.

The delay of certain expected contract extensions and redeployments of existing assets and reduced and declining cash flows in recent periods have caused us to take certain actions to address liquidity needs, including refinancing and extending certain borrowings. Future failure to extend contracts and redeploy assets or a deterioration in relevant business conditions may result in even further declines in liquidity that require exploring additional potential sources of financing on terms that may be less favorable than under our current credit facilities and other borrowings. However, there can be no assurance that any such sources of financing will be available to us on acceptable terms, if at all.

If we are unable to access existing or additional financing sources and generate sufficient cash flow to meet our debt obligations, capital expenditure and other business requirements, we may be forced to take actions such as:

•restructuring our debt;

•seeking additional debt or equity capital;

•selling assets or equity interests in certain assets or joint ventures;

•reducing, delaying or canceling our business activities, acquisitions, investments or capital expenditures; or

•seeking bankruptcy protection.

Such measures may not be successful, and additional debt or equity capital may not be available on acceptable terms or enable us to meet our debt obligations, capital expenditure or other obligations. In addition, our existing financing agreements may restrict our ability to implement some of these measures. The sale of certain assets will reduce cash from operations and the cash available for distributions to unitholders. Any failure to make payments of interest and principal on our outstanding indebtedness on a timely basis could lead to cross-defaults under other financing agreements and result in obligations becoming due and commitments being terminated under such agreements and would likely result in a reduction of our credit rating, which in turn could harm our ability to incur additional indebtedness.
