Senior Notes financial

"5.00% Senior Notes, due 2028 (the “Notes”)."

Senior notes are a type of loan that a company borrows from investors, promising to pay it back with interest. They are called "senior" because in case the company faces financial trouble, these lenders are paid back before others. This makes senior notes safer for investors compared to other types of loans or bonds.

Underwriting Agreement financial

"Underwriting Agreement dated April 30, 2026"

An underwriting agreement is a contract where a company selling new stocks or bonds hires financial firms to buy those securities and resell them to investors. It matters because the agreement sets the offering price, number of securities, fees and which party bears the risk if sales fall short—think of it as a promise that the sale will happen and a roadmap investors can use to understand how the new securities reach the market.

Supplemental Indenture financial

"Sixteenth Supplemental Indenture dated May 5, 2026"

A supplemental indenture is a written amendment to the original bond agreement that changes specific terms of a debt contract, such as payment schedules, interest rates, collateral or covenant protections. Investors care because it alters the legal rights and risks tied to a security — like renegotiating a mortgage where the lender and borrower agree to new rules — and can affect a bond’s credit quality, yield and market value.
