Aberdeen, United Kingdom, August 4, 2022 - Altera Infrastructure GP LLC (Altera GP), the general partner of Altera Infrastructure L.P. (Altera or the Partnership), today reported the Partnership’s results for the quarter ended June 30, 2022.

•Revenues of $296.2 million and net loss of $40.0 million, or $(0.11) per common unit, in the second quarter of 2022.

•Adjusted EBITDA(1) of $129.1 million in the second quarter of 2022.

(2)See the unaudited interim condensed consolidated statements of income (loss) below for additional information.

The Partnership generated net loss of $40 million for the three months ended June 30, 2022, compared to net loss of $28 million for the three months ended June 30, 2021. The decrease of $12 million was primarily due to vessel impairments in the current period, absence of contribution from the Knarr FPSO going off contract May 1, 2022 and higher interest expenses in the second quarter of 2022, partially offset by higher Petrojarl I oil price tariff revenue, higher shuttle tanker utilization and lower depreciation expenses following impairments in the fourth quarter, compared to the same period during the prior year.

Adjusted EBITDA was $129 million for the three months ended June 30, 2022, compared to $110 million for the same period during the prior year. The increase of $19 million was primarily driven by higher Petrojarl I oil price tariff revenue and higher shuttle tanker utilization, partially offset by the absence of contribution from the Knarr FPSO going off contract May 1, 2022.

(1)These operating segments are regularly reviewed by the Partnership's chief operating decision maker (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 defined in this release under the heading “Non-IFRS Measures." Adjusted EBITDA is also used by external users of the Partnership's consolidated financial statements, such as investors and the Partnership’s controlling unitholder.

(2)See the unaudited interim condensed consolidated statements of income (loss) below for additional information.

Second Quarter 2022 Compared with Second Quarter 2021

The Partnership's FPSO segment generated Adjusted EBITDA of $53 million for the three months ended June 30, 2022, compared to $45 million for the three months ended June 30, 2021. The increase of $8 million was primarily due to Petrojarl I higher uptime and oil price tariff revenues, partially offset by an absence of contribution from the Knarr FPSO going off contract May 1, 2022.

The Partnership's Shuttle Tanker segment generated Adjusted EBITDA of $69 million for the three months ended June 30, 2022, compared to $58 million for the three months ended June 30, 2021. The increase of $11 million was primarily due to higher shuttle tanker utilization.

The Partnership's FSO segment generated Adjusted EBITDA of $11 million for the three months ended June 30, 2022, compared to $10 million for the three months ended June 30, 2021.

The Partnership's UMS segment generated an Adjusted EBITDA loss of $4 million for the three months ended June 30, 2022, compared to $2 million for the three months ended June 30, 2021. The $2 million increased loss was primarily due to mobilization costs for the Arendal Spirit UMS for its current contract as compared to being in lay-up in the prior year.

The Partnership's Towage segment generated Adjusted EBITDA of $4 million for the three months ended June 30, 2022, compared to an Adjusted EBITDA loss of $1 million for the three months ended June 30, 2021. The improvement of $5 million was primarily due to higher average day rates and utilization.

Liquidity Update
As at June 30, 2022, the Partnership had total liquidity of $186 million, compared to $241 million as at June 30, 2021, representing a decrease of $55 million.(1)

Financings

The Partnership has engaged with certain of its asset level secured lenders within its FPSO, FSO, Towage, and UMS segments to better align the terms of such debt with expected cash-flows from the applicable segment and with Brookfield Business Partners L.P. and its affiliates (or Brookfield) as secured lender to address its secured debt. The Partnership also anticipates engaging with its unsecured corporate level lenders to address its unsecured debt. As part of these efforts, the Partnership entered into extension agreements with certain of its lenders on June 16, 2022 to defer certain required payments until August 12, 2022. Furthermore, in July 2022, the Partnership opted not to make the interest payment due on July 15, 2022 for its 8.50% senior unsecured bonds with a principal amount outstanding of $276 million that mature in July 2023, and has elected to enter into a 30-day grace period for this interest payment.

Contract Updates

In June 2022, Equinor ASA exercised a one-year extension option for the Randgrid FSO. The extended firm contract is effective until October 2023.

In May 2022, the Knarr FPSO ceased production on the Knarr field in the North Sea, after which decommissioning activities related to the field commenced.

Shuttle Tanker Newbuildings

In May 2022, the Partnership's final newbuilding in a series of seven, the shuttle tanker Altera Thule, commenced operations off the East Coast of Canada.

Vessel Sales

In July 2022, the Partnership sold the ALP Ace and ALP Ippon towage vessels for continued use in a non-competing industry for a total of $14 million.

In July 2022, the Partnership entered into an agreement to sell its 50% owned vessel, the Navion Gothenburg shuttle tanker for continued use for approximately $25 million (100%). Delivery is expected in August 2022.

For additional information, please refer to Part I, Item 1. – Financial Statements: Note 2c ii) – Significant Accounting Policies in the Partnership's Report on Form 6-K for the period ended June 30, 2022.

Non-IFRS Measures

To supplement the unaudited interim condensed consolidated financial statements, the Partnership uses Adjusted EBITDA, which is a non-IFRS financial measure, as a measure of the Partnership's performance. Adjusted EBITDA represents net income (loss) before interest expense, interest income, income tax (expense) benefit, 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 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 the Partnership in assessing its 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; equity-accounted income (loss) and other income (expense), net. 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 intended to provide additional information and should not be considered as the sole measure of the Partnership's 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 the Partnership's management, and the Partnership believes that this supplementary metric assists investors and other users of its financial reports in comparing its financial and operating performance across reporting periods and with other companies.
