First Mortgage Bonds financial

"public offering and sale of $500,000,000 aggregate principal amount of its 5.500% First Mortgage Bonds, Series GGG"

First mortgage bonds are debt securities backed by a company’s property, granting bondholders the primary legal claim to that real estate if the issuer cannot pay. Think of them as being first in line for repayment, like a homeowner’s mortgage lender who gets paid before other creditors. For investors, this priority and the tangible collateral typically make these bonds less risky than unsecured debt, which can mean lower yields but greater protection in bankruptcy.

Supplemental Indenture financial

"The Bonds were issued pursuant to a Supplemental Indenture, dated as of August 21, 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.

aggregate principal amount financial

"public offering and sale of $500,000,000 aggregate principal amount of its 5.500% First Mortgage Bonds"

The aggregate principal amount is the total amount of money borrowed through a bond or loan that the borrower promises to repay. It’s like the original price tag on a loan or bond, showing how much money is involved in the deal. This number matters because it indicates the size of the debt and helps investors understand the scale of the borrowing.

Registration Statement on Form S-3 regulatory

"The sale of the Bonds was registered under the Company’s Registration Statement on Form S-3"

A registration statement on Form S‑3 is a short, standardized filing a qualified public company uses to register new securities with regulators so they can be sold to investors; think of it as a pre-approved, reusable permission slip that speeds up future offerings. It matters to investors because it lets the company raise money more quickly and cheaply — which can fund growth or pay debt — but may also lead to share dilution or change in ownership, so it affects value and liquidity.

underwriting discount financial

"with proceeds to the Company (after deducting the underwriting discount but before deducting"

The underwriting discount is the fee that investment banks or broker-dealers keep when they buy securities from an issuer and resell them to the public; it’s the difference between the price paid to the company and the public offering price, shown per share or as a percentage. It matters to investors because it reduces the cash the company actually raises and is a cost built into the deal—like a sales commission—so a larger discount can mean higher issuance costs, tighter returns for new investors, and a signal about how much effort underwriters must expend to sell the offering.
