Insights

Advanced Energy is retiring its remaining 2.50% convertible notes, giving holders a final chance to convert into equity.

Advanced Energy is calling all $136,709,000 of its 2.50% Convertible Senior Notes due 2028 for redemption on September 23, 2026. The company will pay 100% of principal plus accrued interest, which simplifies its debt profile by removing this convertible layer.

Holders may convert instead of redeeming. Each $1,000 principal amount is currently convertible at a price of about $137.46, based on a 7.2747-share conversion rate, with an extra 0.0743 shares per $1,000 for conversions linked to the redemption notice. Actual equity issued will depend on how many holders choose to convert rather than take cash.

Convertible Senior Notes financial
"all $136,709,000 of its remaining outstanding 2.50% Convertible Senior Notes due 2028"
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.
Indenture financial
"pursuant to Section 16.01 of the Indenture, dated as of September 12, 2023"
An indenture is a legal agreement between a company that borrows money by issuing bonds and the people who buy those bonds. It explains the rules the company must follow, like paying back the money and keeping certain financial promises. This document helps both sides understand their rights and responsibilities.
conversion rate financial
"based on the Conversion Rate of 7.2747 shares of common stock per $1,000 principal amount of Notes, as adjusted"
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.
Observation Period financial
"The Observation Period (as defined in the Indenture) for all conversions from the date of the Redemption Notice"
An observation period is a defined span of time during which a company, regulator, or clinical team watches and records specific outcomes or behaviors to see whether predetermined conditions are met. Investors care because results observed during this window — such as trial safety and efficacy, regulatory compliance, or achievement of performance targets — often trigger approvals, payments, or changes in a company’s prospects; think of it like a monitoring window that determines whether a project moves forward or stalls.
forward-looking statements financial
"This press release may contain, in addition to historical information, forward-looking statements within the meaning of Section 27A"
Forward-looking statements are predictions or plans that companies share about what they expect to happen in the future, like estimating sales or profits. They matter because they help investors understand a company's outlook, but since they are based on guesses and assumptions, they can sometimes be wrong.

ADVANCED ENERGY ANNOUNCES REDEMPTION OF ITS REMAINING 2.50% CONVERTIBLE SENIOR NOTES DUE 2028

DENVER, Colo., June 12, 2026 — Advanced Energy Industries, Inc. (“Advanced Energy” or the “Company”) (Nasdaq: AEIS), a global leader in highly engineered, precision power conversion, measurement, and control solutions, announced today that it has issued a notice of redemption (the “Redemption Notice”) to redeem all $136,709,000 of its remaining outstanding 2.50% Convertible Senior Notes due 2028 (CUSIP Number 007973AE0) (the "Notes") on September 23, 2026 (the “Redemption Date”).

The Company is redeeming the Notes pursuant to Section 16.01 of the Indenture, dated as of September 12, 2023 (the “Indenture”), between the Company and U.S. Bank Trust Company, National Association (the “Trustee”). The redemption price is 100% of the principal amount of the Notes, plus accrued but unpaid interest to, but excluding, the Redemption Date.

The Company is electing to settle conversions of Notes by paying cash in respect of the principal portion of the converted Notes and delivering shares of common stock in respect of the remainder (other than cash in lieu of any fractional share). As of the date of the Redemption Notice, each $1,000 principal amount of Notes is convertible into common stock of the Company at a conversion price of approximately $137.46 (based on the Conversion Rate of 7.2747 shares of common stock per $1,000 principal amount of Notes, as adjusted). For Notes converted in connection with the redemption notice, the conversion rate will be increased by 0.0743 additional shares of common stock per $1,000 principal amount of Notes in accordance with Section 14.03 of the Indenture. Holders may surrender their Notes for conversion at any time prior to the close of business (which is 5:00 p.m., New York City time), on September 22, 2026, the scheduled trading day immediately preceding the Redemption Date. Holders of the Notes that wish to convert their Notes must satisfy the requirements set forth in the Notes and the Indenture, including Section 14.02(b) of the Indenture. The Observation Period (as defined in the Indenture) for all conversions from the date of the Redemption Notice and prior to the close of business on the business day immediately preceding the Redemption Date will commence on June 26, 2026, the 61st scheduled trading day immediately preceding the Redemption Date, to September 21, 2026, expected to be the last day of the 60 consecutive trading day period commencing on June 26, 2026.

Upon conversion, a holder will not receive any separate cash payment for accrued and unpaid interest and the Company’s settlement of the conversion obligation shall be deemed to satisfy its obligation to pay the principal amount of the Note and accrued and unpaid interest to, but not including the relevant conversion date.


On the Redemption Date, the redemption price will become due and payable upon each Note to be redeemed and interest thereon shall cease to accrue on and after the Redemption Date. From and after the Redemption Date, unless the Company shall default in the payment of the redemption price, holders of the Notes shall only have the right to receive the redemption price upon surrender of the Notes to the paying agent.

A copy of the Redemption Notice may be obtained from the Trustee, as paying agent, by calling 800-934-6802.
