Borr Drilling issues $300M 2033 convertible notes

Borr Drilling Limited has completed its previously announced offering of convertible senior notes due 2033, raising $300 million in aggregate principal amount.

Rhea-AI Filing Summary

Borr Drilling Limited has completed its previously announced offering of convertible senior notes due 2033, raising $300 million in aggregate principal amount. This total includes $40 million issued when initial purchasers fully exercised their over-allotment option.

The notes are senior, unsecured obligations maturing on May 1, 2033, bearing interest at 3.50% per annum, payable semi-annually starting November 1, 2026. They are convertible into common shares, cash, or a mix at the company’s election, at an initial conversion rate of 125.0000 common shares per $1,000 principal, equivalent to an initial conversion price of about $8.00 per share. This reflects a conversion premium of over 40% versus the $5.70 closing share price on April 14, 2026.

Borr Drilling plans to use the proceeds to repurchase its existing convertible bonds due 2028 and for general corporate purposes. It has agreed with certain holders to repurchase $195.2 million aggregate principal amount of the 2028 convertible bonds, effectively extending part of its debt maturity profile through the new 2033 notes.

Insights

Capital structure analyst

Borr Drilling refinances part of its 2028 converts with new 2033 notes.

Borr Drilling issued convertible senior notes totaling $300 million due 2033 at a 3.50% coupon, with a conversion price near $8.00 per share, over 40% above the recent $5.70 stock price. This combines debt financing with potential future equity conversion.

The company intends to use the proceeds to repurchase $195.2 million of its existing 2028 convertible bonds and for general corporate purposes. This shifts part of its obligations from 2028 to 2033, while the high conversion premium means equity dilution occurs only if the share price rises substantially above the reference level.

Overall impact on leverage and future interest costs depends on the remaining 2028 bonds and how many of the new notes eventually convert. Future disclosures in company filings may provide more detail on the residual 2028 bond balance and any subsequent liability management actions.

convertible senior notes financial

"completed its previously announced offering of convertible senior notes due 2033"

Convertible senior notes are a type of loan that a company issues to investors, which can be turned into company shares later on. They are called "senior" because they are paid back before other debts if the company runs into trouble. This allows investors to earn interest like a loan but also have the chance to own part of the company if its value rises.

aggregate principal amount financial

"The Company sold $300 million aggregate principal amount of the Notes"

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.

conversion rate financial

"The conversion rate for the Notes will initially equal 125.0000 common shares per $1,000"

Conversion rate is the proportion of items, people or contracts that take a desired action out of the total possible — for example the share of website visitors who make a purchase, or the number of convertible bonds that are exchanged for shares. Investors care because it measures how effectively a business or financial instrument turns opportunity into real outcomes, like sales or share issuance, which directly affects revenue, cash flow and ownership dilution.

conversion premium financial

"Such initial conversion price represents a conversion premium of over 40%"

The conversion premium is the extra amount an investor pays for a convertible security (like a convertible bond or preferred share) above the value they would receive if they immediately exchanged it for the underlying stock; it is usually shown as a percentage over that conversion value. It matters because it shows whether investors are paying for interest, protection against share drops, or expected future stock gains—similar to paying extra for a ticket that also includes a flexible voucher you can later swap for goods.

general corporate purposes financial

"use the proceeds from the sale of the Notes to repurchase its existing convertible bonds due 2028 and for general corporate purposes"

"General corporate purposes" refer to the broad range of activities and expenses a company can use its funds for to support its overall operations and growth. This can include things like paying bills, investing in new projects, or strengthening its financial position. For investors, understanding this term helps clarify how a company plans to use its resources to sustain and expand its business over time.
