Borrowings KeyBank Credit Facility On October 27, 2021, TCF, a wholly owned subsidiary of the Company, as borrower, and the Company, as servicer, entered into a credit agreement (as amended, the “KeyBank Credit Agreement”) with the lenders from time-to-time party thereto, KeyBank, as administrative agent and syndication agent, and Wells Fargo, National Association, as collateral custodian and paying agent. The KeyBank Credit Facility includes a commitment of $600.0 million from KeyBank and other banks and allows the Company, through TCF, to borrow up to $690.0 million. Borrowings under the KeyBank Credit Agreement generally bear interest at a rate equal to Adjusted Term SOFR plus 2.85% to 3.25%, subject to the number of eligible loans in the collateral pool. The KeyBank Credit Facility provides for a variable advance rate of up to 62% on eligible first lien loans and up to 47% on eligible second lien loans. The KeyBank Credit Facility includes a three-year revolving period and a two-year amortization period and matures on July 27, 2029, unless extended. Such credit facility is collateralized by all investment assets held by TCF. The KeyBank Credit Agreement contains representations and warranties and affirmative and negative covenants customary for secured financings of this type, including certain financial covenants such as a consolidated tangible net worth requirement and a required asset coverage ratio. The KeyBank Credit Agreement also contains customary events of default (subject to certain grace periods, as applicable), including but not limited to the nonpayment of principal, interest or fees; breach of covenants; inaccuracy of representations or warranties in any material respect; voluntary or involuntary bankruptcy proceedings; and change of control of the borrower without the prior written consent of KeyBank.

2025 Notes Concurrent with the completion of the Private Common Stock Offering, on January 16, 2020, the Company completed its offering of $105.0 million in aggregate principal amount of the unsecured 2025 Notes in reliance upon the available exemptions from the registration requirements of the Securities Act (the “144A Note Offering”). Keefe, Bruyette & Woods, Inc. (“KBW”), as the initial purchaser, exercised in full its option to purchase or place additional 2025 Notes and on January 29, 2020, the Company issued and sold an additional $20.0 million in aggregate principal amount of the 2025 Notes. As a result, the Company issued and sold a total of $125.0 million in aggregate principal amount of the 2025 Notes pursuant to the 144A Note Offering. Concurrent with the closing of the 144A Note Offering, on January 16, 2020, the Company entered into a registration rights agreement for the benefit of the purchasers of the 2025 Notes in the 144A Note Offering. Pursuant to the terms of this registration rights agreement, the Company filed with the SEC a registration statement, which was initially declared effective on October 20, 2020, registering the public resale of the 2025 Notes by the holders thereof that elected to include their 2025 Notes in such registration statement. The 2025 Notes were issued pursuant to an Indenture dated as of January 16, 2020 (the “Base Indenture”), between the Company and U.S. Bank National Association, as trustee (together with its successor in interest, U.S. Bank Trust Company, National Association, the “Trustee”), and a First Supplemental Indenture, dated as of January 16, 2020 (the “First Supplemental Indenture” and together with the Base Indenture, the “2025 Notes Indenture”), between the Company and the Trustee. The 2025 Notes mature on January 16, 2025 (the “Maturity Date”), unless repurchased or redeemed in accordance with their terms prior to such date. The 2025 Notes are redeemable, in whole or in part, at any time, or from time to time, at the Company’s option, on or after January 16, 2023 at a redemption price equal to 100% of the outstanding principal amount thereof, plus accrued and unpaid interest to, but excluding, the date of redemption. The holders of the 2025 Notes do not have the option to have the notes repaid or repurchased by the Company prior to the Maturity Date. On July 22, 2022, the Company issued $50.0 million in aggregate principal amount of the 2025 Notes in an additional issuance of such 2025 Notes. On July 27, 2022, the underwriters exercised, in full, their option to purchase from the Company an additional $7.5 million in aggregate principal amount of the 2025 Notes solely to cover over-allotments in accordance with the Underwriting Agreement. The 2025 Notes issued pursuant to this offering are treated as a single series with the existing 2025 Notes under the 2025 Notes Indenture (the “Existing 2025 Notes”) and have the same terms as the Existing 2025 Notes (other than issue date and issue price). The 2025 Notes have the same CUSIP number and are fungible and rank equally. In connection with the additional issuance of the 2025 Notes, the 2025 Notes began trading on the Nasdaq Global Select Market under the symbol “TRINL” on July 29, 2022. The 2025 Notes bear interest at a fixed rate of 7.00% per year payable quarterly on March 15, June 15, September 15, and December 15 of each year, commencing on March 15, 2020. The 2025 Notes are direct, general unsecured obligations of the Company and rank pari passu, or equal in right of payment, with all of the Company’s existing and future unsecured indebtedness or other obligations that are not so subordinated. On May 17, 2024 (the “May Redemption”), the Company redeemed $30.0 million in aggregate principal amount of the $182.5 million in aggregate principal amount of the then outstanding 2025 Notes.

For additional information regarding the 2025 Notes, see “Note 15 – Subsequent Events.” 6.00% Convertible Notes due 2025 On December 11, 2020, the Company completed a private offering (the “Private Convertible Note Offering”) of $50.0 million in aggregate principal amount of its unsecured Convertible Notes in reliance upon the available exemptions from the registration requirements of the Securities Act. KBW acted as the initial purchaser and placement agent in connection with the Private Convertible Note Offering pursuant to a purchase/placement agreement dated December 4, 2020, by and between the Company and KBW. The Convertible Notes were issued pursuant to the Base Indenture and a Second Supplemental Indenture, dated as of December 11, 2020 (the “Second Supplemental Indenture” and together with the Base Indenture, the “Convertible Notes Indenture”), between the Company and the Trustee. Concurrent with the closing of the Convertible Note Offering, on December 11, 2020, the Company entered into a registration rights agreement for the benefit of the holders of the Convertible Notes and the shares of common stock issuable upon conversion thereof. Aggregate offering costs in connection with the Convertible Note Offering, including the initial purchaser and placement agent discount and commissions, were approximately $1.9 million which were capitalized and deferred. The Convertible Notes bear interest at a fixed rate of 6.00% per year, subject to additional interest upon certain events, payable semiannually in arrears on May 1 and November 1 of each year, beginning on May 1, 2021. If an investment grade rating is not maintained with respect to the Convertible Notes, additional interest of 0.75% per annum will accrue on the Convertible Notes until such time as the Convertible Notes have received an investment grade rating of “BBB-” (or its equivalent) or better. The rating remained at investment grade as of December 31, 2024. The Convertible Notes mature on December 11, 2025 (the “Convertible Notes Maturity Date”), unless earlier converted or repurchased in accordance with their terms. Holders may convert their Convertible Notes, at their option, at any time on or prior to the close of business on the business day immediately preceding the Convertible Notes Maturity Date. The conversion rate was initially 66.6667 shares of the Company’s common stock, per $1,000 principal amount of the Convertible Notes (equivalent to an initial conversion price of approximately $15.00 per share of common stock). Effective immediately after the close of busines s on December 31, 2024, the conversion rate changed to 81.6439 shares of the Company’s common stock, per $1,000 principal amount of the Convertible Notes (equivalent to a conversion price of approximately $12.25 per share of common stock) as a result of a certain cash dividend of the Company. The conversion rate will be subject to adjustment in some events but will not be adjusted for any accrued and unpaid interest. In addition, following certain corporate events, further described in the Convertible Note Indenture, that occur prior to the Convertible Notes Maturity Date, the Company will increase the conversion rate for a holder who elects to convert its Convertible Notes in connection with such a corporate event in certain circumstances. Upon conversion of the Convertible Notes, the Company will pay or deliver, as the case may be, cash, shares of common stock, or a combination of cash and shares of common stock, at the Company’s election, per $1,000 principal amount of the Convertible Notes, equal to the then existing conversion rate. At the Company’s option, it may cause holders to convert all or a portion of the then outstanding principal amount of the Convertible Notes plus accrued but unpaid interest, at any time on or prior to the close of business on the business day immediately preceding the Convertible Notes Maturity Date, if the closing sale price of the Company’s common stock for any 30 consecutive trading days exceeds 120% of the conversion price, as may be adjusted. Upon such conversion, the Company will pay or deliver, as the case may be, cash, shares of common stock, or a combination of cash and shares of common stock, at the Company’s election, per $1,000 principal amount of the Convertible Notes, equal to the then existing conversion rate, and a forced conversion make-whole payment (as defined in the Second Supplemental Indenture), if any, in cash. Otherwise, the Company may not redeem the Convertible Notes at its option prior to maturity. In addition, if the Company undergoes a fundamental change (as defined in the Second Supplemental Indenture), holders may require the Company to repurchase for cash all or part of such holders’ Convertible Notes at a repurchase price equal to 100% of the principal amount of the Convertible Notes to be repurchased, plus accrued and unpaid interest to, but excluding, the fundamental change repurchase date. The Convertible Notes are direct unsecured obligations of the Company and rank pari passu, or equal in right of payment, with all of the Company’s existing and future unsecured indebtedness or other obligations that are not so subordinated, and senior in right of payment to all of the Company’s future indebtedness or other obligations that are expressly subordinated, or junior, in right of payment to the Convertible Notes. The Convertible Notes are accounted for in accordance with ASC 470-20, Debt Instruments with Conversion and Other Options. In accounting for the Convertible Notes, the Company estimated at the time of issuance that the values of the debt and the embedded conversion feature of the Convertible Notes were approximately 99.1% and 0.9%, respectively. The original issue discount of 0.9%, or approximately $0.5 million, attributable to the conversion feature of the Convertible Notes was recorded in “capital in excess of par value” in the Consolidated Statements of Assets and Liabilities as of December 31, 2020.
