[1] All debt investments are income producing unless otherwise noted. All equity and warrant investments are non-income producing unless otherwise noted. Equipment financed under our equipment financing investments relates to operational equipment essential to revenue production for the portfolio company in the industry noted.
[2] All portfolio companies are located in North America or Europe. As of March 31, 2025, Trinity Capital Inc. (the "Company") had six foreign domiciled portfolio companies, two of which are based in Canada and four of which are based in Europe. In total, these foreign domiciled portfolio investments represent 9.5% of total net asset value based on fair value. The Company generally acquires its investments in private transactions exempt from registration under the Securities Act of 1933, as amended (the “Securities Act”). These investments are generally subject to certain limitations on resale and may be deemed to be “restricted securities” under the Securities Act.
[3] Preferred stock represents investments through which the Company will have preference in liquidation rights and do not contain any cumulative preferred dividends.
[4] Except as noted, all investments were valued at fair value as determined in good faith by the Company’s Board of Directors (the “Board”) using Level 3 inputs.
[5] Interest rate is the fixed or variable rate of the debt investments and does not include any original issue discount, end-of-term (“EOT”) payment, or additional fees related to such investments, such as deferred interest, commitment fees, prepayment fees or exit fees. EOT payments are contractual payments due in cash at the maturity date of the loan, including upon prepayment, and are a fixed rate determined at the inception of the loan. At the end of the term of certain equipment financings, the borrower has the option to purchase the underlying assets at fair value, generally subject to a cap, or return the equipment and pay a restocking fee. The fair values of the financed assets have been estimated as a percentage of original cost for purpose of the EOT payment value. The EOT payment is amortized and recognized as non-cash income over the term of the loan or equipment financing prior to its payment and is included as a component of the cost basis of the Company’s current debt securities.
[6] Investment is on non-accrual status as of March 31, 2025 and is therefore considered non-income producing.
[7] The interest rate on variable interest rate investments represents a benchmark rate plus spread. The benchmark interest rate is subject to an interest rate floor. As of March 31, 2025, the U.S. Prime Rate (“Prime”) was 7.50% and the Secured Overnight Financing Rate (“SOFR”) 30 Day Forward Rate and 3-Month Term Rate were 4.32% and 4.28%, respectively.
[8] Investment is pledged as collateral supporting amounts outstanding under the Company's credit facility with KeyBank, National Association (the “KeyBank Credit Facility”). See “Note 5 – Borrowings” for more information.

[11] All debt investments are income producing unless otherwise noted. All equity and warrant investments are non-income producing unless otherwise noted. Equipment financed under our equipment financing investments relates to operational equipment essential to revenue production for the portfolio company in the industry noted.
[12] All portfolio companies are located in North America or Europe. As of December 31, 2024, Trinity Capital Inc. (the “Company”) had five foreign domiciled portfolio companies, two of which are based in Canada and three of which are based in Europe. In total, these foreign domiciled portfolio investments represent 6.3% of total net asset value based on fair value. The Company generally acquires its investments in private transactions exempt from registration under the Securities Act of 1933, as amended (the “Securities Act”). These investments are generally subject to certain limitations on resale and may be deemed to be “restricted securities” under the Securities Act.
[13] Except as noted, all investments were valued at fair value as determined in good faith by the Company’s Board of Directors (the “Board”) using Level 3 inputs.
[14] This investment is deemed to be a “Control Investment” or an “Affiliate Investment.” The Company classifies its investment portfolio in accordance with the requirements of the 1940 Act. The 1940 Act defines Control Investments as investments in companies in which the Company owns beneficially, either directly or indirectly, more than 25% of the voting securities, or maintains greater than 50% of the board representation. Affiliate Investments are defined by the 1940 Act as investments in companies in which the Company owns beneficially, either directly or indirectly, between 5% and 25% (inclusive) of the voting securities and does not have rights to maintain greater than 50% of the board representation. Fair value as of March 31, 2025, along with transactions during the three months ended March 31, 2025 in these control and affiliate investments are as follows:

[17] Interest rate is the fixed or variable rate of the debt investments and does not include any original issue discount, end-of-term (“EOT”) payment, or additional fees related to such investments, such as deferred interest, commitment fees, prepayment fees or exit fees. EOT payments are contractual payments due in cash at the maturity date of the loan, including upon prepayment, and are a fixed rate determined at the inception of the loan. At the end of the term of certain equipment financings, the borrower has the option to purchase the underlying assets at fair value, generally subject to a cap, or return the equipment and pay a restocking fee. The fair values of the financed assets have been estimated as a percentage of original cost for purpose of the EOT payment value. The EOT payment is amortized and recognized as non-cash income over the term of the loan or equipment financing prior to its payment and is included as a component of the cost basis of the Company’s current debt securities.
[18] The interest rate on variable interest rate investments represents a benchmark rate plus spread. The benchmark interest rate is subject to an interest rate floor. As of December 31, 2024, the U.S. Prime Rate (“Prime”) was 7.50% and the Secured Overnight Financing Rate (“SOFR”) 30 Day Forward Rate and 3-Month Term Rate were 4.33% and 4.31%, respectively.
