(1) Relates to non-cash accretion, write-offs, amortization or other adjustments on (i) debt or lease obligations assumed as part of the 2017 merger with Navig8 Product Tankers Inc. ("NPTI"), which were recorded at fair value on the closing dates, (ii) the carrying values of certain sale and leaseback arrangements related to the notifications to exercise purchase options; and (iii) our Unsecured Senior Notes Due 2025, as discussed below. Interest Rate Benchmark Reform Interest in most of our financing agreements has historically been based on published rates for LIBOR. The ICE Benchmark Administration (“IBA”), the administrator of LIBOR, with the support of the United States Federal Reserve and the United Kingdom’s Financial Conduct Authority, ceased the publication of all U.S. Dollar LIBOR tenors on June 30, 2023. In response to the anticipated discontinuation of LIBOR, the Alternative Reference Rate Committee, a committee convened by the Federal Reserve that includes major market participants, proposed an alternative rate to replace U.S. Dollar LIBOR: the Secured Overnight Financing Rate, or “SOFR.” During the year ended December 31, 2023, we transitioned our existing loan and lease financing agreements from U.S. Dollar LIBOR to SOFR plus a credit spread adjustment (“CSA”) which varied from zero basis points to 26.161 basis points depending on the financing arrangement. We have applied the practical expedient pursuant to the Amendments to IFRS 9 – Financial Instruments (IBOR reform) as our secured bank debt and lease financing arrangements are carried at amortized cost, and therefore the change in the effective interest rate on these arrangements that has arisen from IBOR reform was deemed to be economically equivalent to the previous basis. Accordingly, no gain or loss was recognized upon transition. Secured Bank Debt Each of our secured credit facilities contains financial and restrictive covenants, which require us to, among other things, comply with certain financial tests (described below); deliver quarterly and annual financial statements and annual projections; comply with restrictive covenants, including maintaining adequate insurances; comply with laws (including environmental laws and ERISA); and maintain flag and class of our vessels. Other such covenants may, among other things, restrict consolidations, mergers or sales of our assets; require us to obtain lender approval on changes in our vessel manager; limit our ability to place liens on our assets; limit our ability to incur additional indebtedness; prohibit us from paying dividends if there is a covenant breach under the loan or an event of default has occurred or would occur as a result of payment of such dividend; or prohibit our transactions with affiliates. Furthermore, our debt agreements contain customary events of default, including cross-default provisions, as well as subjective acceleration clauses under which the debt could become due and payable in the event of a material adverse change in the Company’s business. These secured credit facilities may be secured by, among other things: •a first priority mortgage over the relevant collateralized vessels; •a first priority assignment of earnings, insurances and charters from the mortgaged vessels for the specific facility; •a pledge of earnings generated by the mortgaged vessels for the specific facility; and •a pledge of the equity interests of each vessel owning subsidiary under the specific facility. Each of our secured credit facilities are described below. Hamburg Commercial Bank Credit Facility In November 2019, we executed an agreement with Hamburg Commercial Bank AG for a senior secured term loan facility for $43.65 million (the "Hamburg Commercial Bank Credit Facility"), of which, (i) $42.2 million (Tranche 1) was used to refinance the existing debt for STI Veneto and STI Poplar, and (ii) $1.4 million (Tranche 2) was used to finance the purchase and installation of a scrubber on STI Veneto. The amount outstanding as of December 31, 2022 was $33.7 million. The outstanding debt on this loan facility was repaid in full in September 2023 and the loan facility was terminated. Prudential Credit Facility In November 2019, we executed an agreement with Prudential Private Capital for a senior secured term loan facility for $55.5 million (the "Prudential Credit Facility"). The Prudential Credit Facility was fully drawn in December 2019, with the primary purpose of refinancing STI Clapham, STI Camden and STI Acton. The Prudential Credit Facility bears interest at the benchmark rate (LIBOR and SOFR plus a CSA) plus a margin of 3.00% per annum. Our Prudential Credit Facility includes financial covenants that require us to maintain: •The ratio of net debt to total capitalization no greater than 0.60 to 1.00. •Consolidated tangible net worth of no less than $1.0 billion plus (i) 25% of the cumulative positive net income (on a consolidated basis) for each fiscal quarter commencing on or after January 1, 2016 and (ii) 50% of the net proceeds of new equity issuances occurring on or after January 1, 2016. •Minimum liquidity of not less than the greater of $25.0 million and $500,000 per each owned vessel plus $250,000 per each time chartered-in vessel. •The aggregate of the fair market value of the vessels provided as collateral under the facility shall be no less than 125% of the loan outstanding.

The loan is comprised of two facilities: (i) an ECA facility of $47.2 million (which is comprised of a $41.6 million tranche which is guaranteed by GIEK, or the “GIEK Tranche”, and a $5.6 million commercial tranche or the “Commercial Bank Tranche”) and (ii) a commercial facility of $8.3 million, or the “Commercial Facility." The amount outstanding as of December 31, 2022 was $38.3 million. The outstanding debt on this loan facility was repaid in full in August 2023 and the loan facility was terminated. BNPP Sinosure Credit Facility In December 2019, we executed a senior secured term loan facility with BNP Paribas and Skandinaviska Enskilda Banken AB for up to $134.1 million. This loan is split into two facilities, (i) a commercial facility for up to $67.0 million (the "Commercial Facility"), and (ii) a Sinosure facility for up to $67.0 million (the "Sinosure Facility"), which was funded by the lenders under the commercial facility and insured by the China Export & Credit Insurance Corporation ("Sinosure") and is currently being used to finance five of our vessels. These facilities are collectively referred to as the BNPP Sinosure Credit Facility. During the years ended December 31, 2020, 2021 and 2022, we drew down an aggregate $101.5 million, $1.9 million and $5.1 million, respectively. The Sinosure Facility and the Commercial Facility bear interest at the benchmark rate (LIBOR and SOFR plus a CSA) plus a margin of 1.80% and 2.80% per annum, respectively. The Sinosure Facility is scheduled to be repaid in semi-annual principal installments, in aggregate, of $5.5 million through October 2024, $3.4 million in April 2025 and $0.9 million in October 2025. The Commercial Facility is scheduled to be repaid at the final maturity date of the facility, or October 2025.

For each arrangement, we have evaluated whether, in substance, these transactions are leases or merely a form of financing. As a result of this evaluation, we have concluded that each agreement is a form of financing on the basis that each transaction is a sale and leaseback transaction which does not meet the criteria for a sale under IFRS 15. Accordingly, the cash received in the transfer has been accounted for as a liability under IFRS 9, and each arrangement has been recorded at amortized cost using the effective interest method, with the corresponding vessels being recorded at cost, less accumulated depreciation, on our consolidated balance sheet. The obligations set forth below are secured by, among other things, assignments of earnings and insurances and stock pledges and account charges in respect of the subject vessels. All of the financing arrangements contain customary events of default, including cross-default provisions as well as subjective acceleration clauses under which the lessor could cancel the lease in the event of a material adverse change in the Company’s business. Given the favorable market conditions during the years ended December 31, 2023 and 2022, we were able exercise purchase options and repay the lease obligations on 53 vessels. In all circumstances, we submitted binding notices to exercise the purchase options prior to the end of the lease term in accordance with the existing provisions of the leases. As these instruments were accounted for as financial liabilities at amortized cost under IFRS 9, the submission of the purchase option notice triggered a re-assessment of the cash flows associated with the liability. As almost all of these instruments were floating rate financial liabilities, the carrying values of the liabilities did not change with the exception of purchase option fees incurred on certain arrangements, all of which are detailed below. For fixed rate instruments, a nominal gain or loss was recorded upon re-assessment. Ocean Yield Lease Financing We assumed the obligations under a lease financing arrangement with Ocean Yield ASA for four LR2 tankers (STI Sanctity, STI Steadfast, STI Supreme, and STI Symphony) in connection with the September 2017 acquisition of Navig8 Product Tankers Inc. (the "Ocean Yield Lease Financing). Under this arrangement, each vessel was subject to a 13-year bareboat charter, which expires between February and August 2029 (depending on the vessel). Charterhire, which is paid monthly in advance, includes a fixed payment in addition to a quarterly adjustment based on prevailing benchmark rates (LIBOR and SOFR plus a CSA). Monthly principal payments are approximately $0.2 million per vessel gradually increasing to $0.3 million per vessel per month until the expiration of the agreement. The interest component of the leases approximates the prevailing benchmark rate plus 5.40% per annum. We also have purchase options to re-acquire each of the vessels during the bareboat charter period, with the first of such options exercisable beginning at the end of the seventh year from the delivery date of the subject vessel. We are subject to certain terms and conditions, including financial covenants, under this arrangement which are summarized as follows: •The ratio of net debt to total capitalization no greater than 0.60 to 1.00. •Consolidated tangible net worth no less than $1.0 billion plus (i) 25% of the cumulative positive net income (on a consolidated basis) for each fiscal quarter commencing on or after January 1, 2016 and (ii) 50% of the net proceeds of new equity issues occurring on or after January 1, 2016. •Minimum liquidity of not less than the greater of $25.0 million or $500,000 per each owned vessel and $250,000 per each time chartered-in vessel. In September 2022, we gave notice to exercise the purchase option on STI Sanctity. The purchase option price for this vessel was $27.8 million, and the purchase closed in March 2023. In October 2022, we gave notice to exercise the purchase options on STI Steadfast and STI Supreme. The purchase option price was $27.8 million per vessel, and the purchases closed in May 2023 and August 2023. The carrying value of the lease obligations related to these vessels was classified as current on the consolidated balance sheet as of December 31, 2022. The carrying values of the amounts due under this arrangement (which reflect fair value adjustments made as part of the initial purchase price allocation of the acquisition along with non-cash adjustments to the carrying values that were triggered by notifications to exercise purchase options) were $25.2 million and $114.3 million as of December 31, 2023 and 2022, respectively. We were in compliance with the financial covenants as of those dates. BCFL Lease Financing (LR2s) We assumed the obligations of a lease financing arrangement with Bank of Communications Finance Leasing Co Ltd., or BCFL, for three LR2 tankers (STI Solace, STI Solidarity, and STI Stability) as part of the September 2017 acquisition of NPTI (the "BCFL Lease Financing (LR2s)"). Under the arrangement, each vessel was subject to a 10-year bareboat charter which was scheduled to expire in July 2026. Charterhire under the arrangement was determined in advance, on a quarterly basis and was calculated by determining the payment based off of the then outstanding balance, the time to expiration and an interest rate of the benchmark rate (LIBOR and LIBOR as of June 30, 2023) plus 3.50% per annum. In April 2020, we executed an agreement to increase the borrowing capacity of our BCFL Lease Financing arrangements (LR2s) by up to $1.9 million per vessel to partially finance the purchase and installation of scrubbers on the above vessels. The agreement was for a fixed term of three years at the rate of up to $1,910 per vessel per day to be allocated to principal and interest. In July 2020, we drew $1.9 million to partially finance the purchase and installation of a scrubber on one vessel, and in January 2021, we drew $3.8 million to partially finance the purchase and installation of scrubbers on two vessels. In December 2023, we exercised the purchase options on all of the vessels under this arrangement and repaid the outstanding indebtedness of $58.4 million as part of these transactions, thus terminating the leases. Additionally, we had an aggregate of $0.8 million on deposit in a deposit account, in accordance with the terms and conditions of this facility, which were not freely available and was recorded as non-current Restricted Cash on our consolidated balance sheets as of December 31, 2022. This deposit account was released after the exercise of the purchase options on the vessels in December 2023. CSSC Lease Financing We assumed the obligations under a lease financing arrangement with CSSC (Hong Kong) Shipping Company Limited, or CSSC, for eight LR2 tankers (STI Gallantry, STI Nautilus, STI Guard, STI Guide, STI Goal, STI Gauntlet, STI Gladiator and STI Gratitude) as part of the September 2017 acquisition of NPTI (the "CSSC Lease Financing"). This arrangement was amended and restated in 2019 and 2021 to, among others, increase the borrowing capacity and reduce the margin. The tenor of the amended and restated lease remained unchanged, with each lease scheduled to expire throughout 2026 and 2027; however, the amended and restated lease contained an option to extend the lease for each vessel by an additional 24 months. The interest under the amended and restated agreement was reduced to the prevailing benchmark rate (LIBOR and SOFR plus a CSA) plus a margin of 3.50% per annum and the principal balance was scheduled to be repaid in equal installments of approximately $0.2 million per vessel per month. Each lease also contained purchase options to re-acquire each of the subject vessels beginning on the second anniversary date from the effective date of the amended agreement, with a purchase obligation for each vessel upon the expiration of each agreement. In October and November 2020, we repaid $81.7 million and paid a $1.6 million prepayment fee when we refinanced the existing debt on STI Nautilus, STI Guard, and STI Gallantry. In October 2023, we exercised the purchase options on all of the remaining vessels under this arrangement, repaid the outstanding indebtedness of $110.4 million, and paid purchase option fees of $1.7 million as part of these transactions. These leases were terminated as a result of these transactions. BCFL Lease Financing (MRs) In September 2017, we entered into agreements to sell and lease back five 2012 built MR product tankers (STI Amber, STI Topaz, STI Ruby, STI Garnet and STI Onyx) with Bank of Communications Finance Leasing Co Ltd., or BCFL, for a sales price of $27.5 million per vessel (the "BCFL Lease Financing (MRs)"). The financing for STI Topaz, STI Ruby and STI Garnet closed in September 2017, the financing for STI Onyx closed in October 2017, and the financing for STI Amber closed in November 2017. Each agreement was for a fixed term of seven years at a bareboat rate of $9,025 per vessel per day, with three consecutive one-year options to extend each charter beyond the initial term. Furthermore, we had the option to purchase these vessels beginning at the end of the fifth year of the agreements through the end of the tenth year of the agreements. A deposit of $5.1 million per vessel was retained by the buyers and will either be applied to the purchase price of the vessel if a purchase option is exercised or refunded to us at the expiration of the agreement (as applicable). In April 2020, we executed an agreement to increase the borrowing capacity by up to $1.9 million per vessel to partially finance the purchase and installation of scrubbers on the above vessels. The agreement was for a fixed term of three years at the rate of up to $1,910 per vessel per day to be allocated to principal and interest. In July 2020, we drew $1.9 million to partially finance the purchase and installation of a scrubber on one vessel and in January 2021, we drew $5.8 million to partially finance the purchase and installation of scrubbers on three vessels. Our BCFL Lease Financing (MRs) includes a financial covenant that requires us to maintain that the aggregate of the fair market value of each vessel leased under the facility plus the aforementioned $5.1 million deposit shall at all times be no less than 100% of the then outstanding balance plus the aforementioned $5.1 million deposit. In November 2023, we exercised the purchase option on STI Amber prior to its sale and repaid the outstanding indebtedness of $8.2 million, which was net of the vessel deposit, as part of this transaction, thus terminating the lease. In November 2023, we gave notice to exercise the purchase options on the remaining four vessels. In December 2023, we closed on the purchase of STI Ruby and repaid the outstanding indebtedness of $7.4 million, which was net of the vessel deposit, as part of this transaction, thus terminating the lease. The purchases of STI Topaz, STI Garnet and STI Onyx closed in January 2024 (see Note 23).

In December 2020, we executed the agreements on three of the vessels (STI Brooklyn, STI Rose and STI Rambla) and drew down $4.6 million under the upsized portion of this arrangement. The upsized portion of the lease financing had a final maturity of three years after the first drawdown, bearing interest at LIBOR plus a margin of 4.20% per annum.

We recorded an aggregate loss on the extinguishment of the Convertible Notes Due 2022 of $5.5 million as a result of the 2021 Convertible Notes Exchanges. Convertible Notes Due 2025 The Convertible Notes Due 2025 were our senior, unsecured obligations bearing coupon interest at a rate of 3.00% per annum. In addition to the 2021 Convertible Notes Exchanges noted above, during the year ended December 31, 2021, we issued and sold $118.5 million in aggregate principal amount of Convertible Notes Due 2025 pursuant to separate, privately negotiated, agreements with certain investors in a private offering, which we refer to as the 2021 Convertible Notes Offerings. A portion of the 2021 Convertible Notes Offerings were issued at 102.25% of par, or $43.3 million, plus accrued interest. We determined the initial carrying value of the liability component of the Convertible Notes Due 2025, to be $193.7 million. The residual value, attributable to the conversion feature, of $7.7 million, was recorded to Additional paid-in capital upon issuance. The difference between the fair value of the liability component and the face value of the Convertible Notes Due 2025 was accreted over the term of the Convertible Notes Due 2025 under the effective interest method and recorded as part of financial expenses. Additionally, commencing in March 2021, principal accreted on the principal amount, compounded semi-annually, at a rate equal to approximately 5.5202% per annum, which principal amount, together with any accretions thereon, is the “Accreted Principal Amount”. The Accreted Principal Amount at maturity was expected to equal 125.3% of par, which together with the 3.00% coupon interest rate, compounds to a yield-to-maturity of approximately 8.25%. During the year ended December 31, 2022, we repurchased an aggregate $12.3 million face value of our Convertible Notes Due 2025 in the open market for $14.3 million. The consideration paid included the Accreted Principal Amount. As a result of these transactions, we reduced the liability and equity (the value of the conversion feature) components of the Convertible Notes Due 2025 by $14.8 million and recorded a gain of $0.5 million. In November 2022, we sent a notice of redemption to all holders of the Convertible Notes Due 2025 pursuant to Section 16.01 of the indenture dated March 25, 2021. All of the holders of the Convertible Notes Due 2025 fully converted their notes prior to the Redemption Date, resulting in the issuance of 5,757,698 common shares to settle all amounts outstanding, including accrued but unpaid interest. As it was expected that all holders would convert their notes into shares, the economic substance of the exercise of the early redemption feature was a forced conversion. Therefore, no adjustments to the carrying amounts were made on the announcement of the early redemption. In accordance with IAS 32, we de-recognized the liability component and recognized it as equity, without any gain or loss recorded in profit or loss. The carrying value of the debt at the time of conversions was $198.9 million comprised of: (i) principal (which included the par value and the Accreted Principal Amount which had accrued since the March 2021 issuance date) of $205.1 million; (ii) less, unamortized deferred financing costs of $2.1 million; (iii) less, unamortized value attributable to the conversion feature, net of unamortized premium, of $4.2 million; and (iv) accrued coupon interest of $0.1 million. We incurred $5.2 million of coupon interest and $11.3 million of non-cash accretion (inclusive of the Accreted Principal Amount of $9.8 million) during the year ended December 31, 2022.
