On June 1, 2020, in connection with the consummation of the Mergers with TiVo, the Company entered into a Credit Agreement (the “2020 Credit Agreement”) by and among the Company, the lenders party thereto and Bank of America, N.A., as administrative agent and collateral agent. The 2020 Credit Agreement provides for a five-year senior secured term loan B facility in an aggregate principal amount of $1,050 million (the “2020 Term B Loan Facility”). The interest rate applicable to loans outstanding under the 2020 Term B Loan Facility is equal to, at the Company’s option, either (i) a base rate plus a margin of 3.00% per annum or (ii) LIBOR plus a margin of 4.00% per annum. Commencing on September 30, 2020, the 2020 Term B Loan Facility will amortize in equal quarterly installments in aggregate quarterly amounts equal to (i) with respect to repayments occurring on or prior to June 1, 2023, 1.25% of the original principal amount of the 2020 Term B Loan Facility and (ii) with respect to repayments occurring after June 1, 2023 and prior to June 1, 2025, 1.875% of the original principal amount of the 2020 Term B Loan Facility, with the balance payable on the maturity date of the 2020 Term B Loan Facility (in each case subject to adjustment for prepayments). The 2020 Term B Loan Facility will mature on June 1, 2025. Upon the closing of the 2020 Credit Agreement, the Company borrowed $1,050 million under the 2020 Term B Loan Facility. Net proceeds were used on June 1, 2020, together with cash and cash equivalents, to refinance the existing indebtedness of the combined Company (the “Debt Financing”), including paydown of the TiVo 2019 Term Loan of $734.6 million. See “Note 9 – Business Combination” for additional information relating to the Mergers. Additionally, debt discount and issuance costs of approximately $39.7 million were incurred and capitalized in connection with the 2020 Term B Loan Facility in June 2020.

The Company commenced repaying quarterly installments under the 2020 Term B Loan Facility in the third quarter of 2020, and also elected to make a voluntary principal payment of $150.0 million on December 31, 2020. As outlined in the 2020 Credit Agreement, additional cash payments must be made on an annual basis beginning March 31, 2022 based on certain leverage ratios and excess cash flow generated for the immediately preceding fiscal year. The voluntary principal payment made on December 31, 2020 may be applied against required additional paydowns, if any, beginning March 31, 2022.

The obligations under the 2020 Credit Agreement are guaranteed by Xperi, TiVo and certain other of the Company’s wholly-owned material domestic subsidiaries (collectively, the “Guarantors”) pursuant to the Guaranty, dated as of June 1, 2020 (the “Guaranty”), among Xperi, TiVo, the other Guarantors party thereto and Bank of America, N.A., as administrative agent. The

obligations under the 2020 Credit Agreement are secured by a lien on substantially all of the assets of the Company and the Guarantors pursuant to the Security Agreement, dated as of June 1, 2020 (the “Security Agreement”), among the Company, Xperi, TiVo, the other pledgors party thereto and Bank of America, N.A., as collateral agent.

The 2020 Credit Agreement contains customary events of default, upon the occurrence of which, after any applicable grace period, the lenders will have the ability to accelerate all outstanding loans thereunder. The 2020 Credit Agreement also contains customary representations and warranties and affirmative and negative covenants that, among other things, restrict the ability of the Company and its subsidiaries to create or incur certain liens, incur or guarantee additional indebtedness, merge or consolidate with other companies, transfer or sell assets and make restricted payments. These covenants are subject to a number of limitations and exceptions set forth in the Credit Agreement. The Company was in compliance with all requirements as of December 31, 2020.

On December 1, 2016, in connection with the consummation of the acquisition of DTS, the Company entered into a Credit Agreement (the “Credit Agreement”) by and among the Company, Royal Bank of Canada, as administrative agent and collateral agent, and the lenders party thereto. The Credit Agreement provided for a $600.0 million seven-year term B loan facility (the “Term B Loan Facility”) which was scheduled to mature on November 30, 2023. Upon the closing of the Credit Agreement, the Company borrowed $600.0 million under the Term B Loan facility. Net proceeds were used on December 1, 2016, together with cash and cash equivalents, to finance the acquisition of DTS.

On January 23, 2018, the Company and the loan parties entered into an amendment to the Credit Agreement (the “Amendment”). In connection with the Amendment, the Company made a voluntary prepayment of $100.0 million of the term loan outstanding under the Credit Agreement using cash on hand. The Amendment provided for, among other things, (i) a replacement of the outstanding initial term loan with the new tranche term B-1 loan (the “2018 Amended Term B Loan”) in a principal amount of $494.0 million, (ii) a reduction of the interest rate margin applicable to such loan to (x) in the case of Eurodollar loans, 2.50% per annum and (y) in the case of base rate loans, 1.50% per annum, (iii) a prepayment premium of 1.00% in connection with any repricing transaction with respect to the 2018 Amended Term B Loan within six months of the closing date of the Amendment, and (iv) certain amendments to provide the Company with additional flexibility under the covenant governing restricted payments. Using cash on hand, the Company made three voluntary prepayments totaling $150.0 million during 2019. On June 1, 2020, the entire remaining balance of $344.0 million was paid off by using the proceeds from the 2020 Term B Loan Facility as part of the TiVo Merger transaction. As a result of the refinancing transaction, the Company recorded a loss on early extinguishment of debt of $8.3 million, which consisted of unamortized debt discount and issuance costs, in its Consolidated Statements of Operations for the year ended December 31, 2020.

In connection with the Mergers, the Company paid off all outstanding balance under the TiVo 2019 Term Loan. The 2019 Term Loan Facility Agreement was entered into on November 22, 2019 between TiVo, as borrower, and the lenders party thereto and HPS Investment Partners, LLC as administrative agent and collateral agent. Under the 2019 Term Loan, TiVo borrowed $715.0 million, which matures on November 22, 2024.

Under the 2019 Term Loan Facility Agreement, TiVo was required to pay a 3.0% prepayment premium if the loan was prepaid on or prior to November 22, 2020. Further under the same Loan Facility Agreement, the Mergers triggered certain change of control conditions that constitute an event of default, thus requiring the debt to be repaid immediately following the consummation of the Mergers. Using the proceeds from the aforementioned 2020 Term B Loan Facility, the Company, on June 1, 2020, made a full repayment of the 2019 Term Loan along with the prepayment penalty for a total payoff amount of $734.6 million.

Upon consummation of the TiVo Merger on June 1, 2020, the Company assumed $48.0 thousand of Convertible Senior Notes that were issued by TiVo Solutions Inc. (“TiVo Solutions”) in September 2014 and mature October 1, 2021 (the “2021 Convertible Notes”). The 2021 Convertible Notes bear interest at an annual rate of 2.0%, payable semi-annually in arrears on April 1 and October 1 of each year.

At December 31, 2020, $873.8 million was outstanding with an interest rate, including the amortization of debt discount and issuance costs, of 5.1%. Interest is payable monthly. There were also $34.4 million of unamortized debt discount and issuance costs recorded as a reduction of the long-term portion of the debt. At December 31, 2019, $344.0 million was outstanding with unamortized debt discount and issuance costs amounting to $9.3 million. Interest expense was $37.9 million, $23.4 million and $25.7 million for the years ended December 31, 2020, 2019 and 2018, respectively. Amortized debt discount and issuance costs, which were included in interest expense, amounted to $6.3 million, $2.5 million and $2.5 million for the years ended December 31, 2020, 2019 and 2018, respectively.
