TTM Announces Closings of New Term Loan Facility and New U.S. ABL Facility

Santa Ana, CA – May 30, 2023 – TTM Technologies, Inc. (NASDAQ:TTMI) (“TTM”), a leading global manufacturer of technology solutions including mission systems, radio frequency (“RF”) components and RF microwave/microelectronic assemblies and printed circuit boards (“PCBs”), today announced the closing and syndication of a new $350 million senior secured term loan (the “New Term Loan Facility”) and the closing of a new U.S. asset-based revolving credit facility with committed borrowing capacity of $150 million (the “New U.S. ABL Facility”).

The New Term Loan Facility, which matures May 2030, amends and restates TTM’s previous senior secured term loan facility that was scheduled to mature in September 2024, under which $356 million of indebtedness was outstanding. TTM used the proceeds from its New Term Loan Facility to refinance $350 million of such outstanding indebtedness and used cash on hand to pay the remaining indebtedness as well as to pay related fees and expenses. The New U.S. ABL Facility amends and restates TTM’s previous $150 million U.S. asset-based revolving credit facility, which was scheduled to mature in June 2024.

The New Term Loan Facility was priced at an interest rate of Term SOFR + 2.75%. The new Term B Loans were issued with a 1.0% original issue discount. Annual cash interest expense is expected to increase by $0.9 million.

The maximum availability under the New U.S. ABL Facility is $150 million. The New U.S. ABL Facility is scheduled to mature in May 2028 and has a borrowing rate of Term SOFR plus a margin ranging from 1.35% to 1.6%.

As a result of these transactions, annual non-cash interest expense will increase approximately $0.3 million and TTM will record, in the second quarter of 2023, a non-cash expense of approximately $1.3 million for the write off of debt issuance costs.

The New Term Loan Facility was entered into with J.P. Morgan acting as administrative agent and joint lead arranger. Other joint lead arrangers for the New Term Loan Facility were BofA Securities, Inc., Barclays Bank PLC, Truist Securities, Inc. and HSBC Securities (USA) Inc. The New U.S. ABL Facility was entered into with J.P. Morgan acting as administrative agent.
