P-Caps Trust

On November 17, 2021, the Company raised $400.0 million of contingent liquidity through the issuance and sale by Hill City Funding Trust, a Delaware statutory trust (the P-Caps Trust), of 400,000 of pre-capitalized trust securities redeemable August 15, 2041 (the P-Caps) for an aggregate purchase price of $400.0 million in a private placement pursuant to Rule 144A under the Securities Act of 1933, as amended. In connection with the issuance and sale of the P-Caps, the Company entered into a facility agreement with the P-Caps Trust and The Bank of New York Mellon Trust Company, N.A., as notes trustee, pursuant to which the Company had the right to issue to the P-Caps Trust, and to require the P-Caps Trust to purchase from the Company, on one or more occasions, up to an aggregate principal amount at any one time outstanding of $400.0 million of the Company’s

4.046% Senior Notes due August 15, 2041 (the 2041 Senior Notes), in exchange for all or a portion of the portfolio of principal and interest strips of U.S. Treasury Securities held by the P-Caps Trust (the Trust Assets) corresponding to the amount of the issuance right being exercised at that time.

On October 24, 2024, the Company exercised in full its issuance right under the facility agreement, following which the Company: (i) issued $400.0 million principal amount of the 2041 Senior Notes to the P-Caps Trust on October 28, 2024 in exchange for the Trust Assets; and (ii) directed the trustee of the P-Caps Trust to dissolve the P-Caps Trust in accordance with its declaration of trust and deliver the 2041 Senior Notes to the beneficial holders of the P-Caps pro rata in respect of each P-Cap.

In connection with the dissolution of the P-Caps Trust, the beneficial holders of the P-Caps will receive the 2041 Senior Notes through the facilities of The Depository Trust Company.
