Rhea-AI Filing Summary

Advanced Energy Industries, Inc. is raising capital through a private offering of $1.0 billion aggregate principal amount of 0% Convertible Senior Notes due 2031 to qualified institutional buyers under Rule 144A. The company granted initial purchasers an option for up to an additional $150 million of notes.

Advanced Energy expects net proceeds of about $980.8 million, or $1,128.1 million if the option is fully exercised. It plans to spend $60.0 million (or $69.0 million) on capped call transactions and about $442.4 million in cash plus roughly 1.98 million shares to exchange approximately $438.3 million of its 2.50% Senior Convertible Notes due 2028, with remaining proceeds for general corporate purposes including potential retirement of the rest of the 2028 notes.

The notes carry a 0% coupon, mature on May 15, 2031, and have an initial conversion rate of 1.9655 shares per $1,000 (conversion price about $508.78 per share, a 50% premium to the $339.19 stock price on May 13, 2026). Capped call transactions with a cap price of $678.38 per share are designed to mitigate potential dilution from conversions.

Insights

Large zero-coupon convertible refi shifts AEIS’s debt and dilution profile.

Advanced Energy is issuing $1.0 billion of 0% Convertible Senior Notes due 2031, with an option for another $150 million. Net proceeds of about $980.8 million (or $1,128.1 million) fund capped calls and exchanges of the $438.3 million 2028 convertibles.

The initial conversion price of roughly $508.78 per share reflects a 50% premium to the $339.19 stock price on May 13, 2026, while the capped calls have a higher cap at $678.38 per share, a 100.0% premium. This structure lowers cash interest but introduces long-dated equity-linked exposure and potential dilution if the share price appreciates.

Exchanging part of the 2028 notes for cash and about 1.98 million shares, plus potentially retiring remaining 2028 notes, staggers maturities toward 2031. The company also expects to receive about $44.6 million from unwinding existing hedge and warrant transactions. Subsequent filings may clarify the residual 2028 note balance and any additional liability management steps.

0% Convertible Senior Notes due 2031 financial
"pricing of an offering of $1 billion aggregate principal amount of its 0% Convertible Senior Notes due 2031"
Rule 144A regulatory
"offered only to persons reasonably believed to be qualified institutional buyers in accordance with Rule 144A"
Rule 144A is a regulation that makes it easier for companies to sell private bonds to large investors without going through all the usual rules that apply to public sales. It matters because it helps companies raise money more quickly and privately, often attracting big investors looking for special deals.
capped call transactions financial
"use $60.0 million of the net proceeds from the offering to pay the cost of the capped call transactions"
Capped call transactions are agreements where investors buy options that give them the chance to benefit if a stock's price goes up, but with a limit on how much they can gain. This helps protect them from paying too much if the stock's price rises a lot, similar to having a maximum limit on a reward. They matter because they help investors manage risk while still allowing some upside potential.
fundamental change regulatory
"If Advanced Energy undergoes a fundamental change (as defined in the indenture governing the notes), holders may require Advanced Energy to repurchase"
A fundamental change is a major shift in how a company or economy operates, like a new technology or a big change in leadership. It matters because such changes can affect the value or stability of investments, making them more or less attractive. Think of it like a major upgrade or shift in the rules of a game that can change the outcome.
convertible note hedge transactions financial
"entered into convertible note hedge transactions (the "existing convertible note hedge transactions") with certain financial institutions"
Convertible note hedge transactions are agreements made alongside convertible debt that limit the market impact when those notes convert into shares by using separate contracts that offset or neutralize the new stock issuance (for example, arranging share sales, purchases, or option contracts). Investors care because these hedges can reduce or delay dilution and dampen price swings—think of them like insurance that limits how much a conversion can dilute existing owners or move the stock price.
warrant transactions financial
"entered into separate warrant transactions (the "existing warrant transactions") with the existing counterparties"
Warrant transactions are the issuance, sale, transfer, exercise or cancellation of warrants — contracts that give a holder the right to buy a company’s shares at a set price for a set period. Investors care because exercising warrants can raise cash for the company but also increase the number of shares outstanding, diluting existing ownership and potentially affecting the stock price; think of warrants like gift certificates that can be turned in later for a product at a fixed cost.

ADVANCED ENERGY ANNOUNCES PRICING OF $1 BILLION 0% CONVERTIBLE SENIOR NOTES

DENVER, Colo., May 13, 2026 — Advanced Energy Industries, Inc. (“Advanced Energy”) (Nasdaq: AEIS), a global leader in highly engineered, precision power conversion, measurement, and control solutions, announced today the pricing of its private offering of $1.0 billion aggregate principal amount of 0% Convertible Senior Notes due 2031 (the “notes”) at a premium of approximately 50% over the closing price of Advanced Energy’s common stock of $339.19 per share on May 13, 2026. The notes were offered only to persons reasonably believed to be qualified institutional buyers in accordance with Rule 144A under the Securities Act of 1933, as amended (the “Securities Act”). Advanced Energy has also granted to the initial purchasers of the notes an option to purchase, for settlement within a 13-day period beginning on, and including, the date on which the notes are first issued, up to an additional $150 million aggregate principal amount of the notes. The offering of the notes, the capped call transactions, the unwind of the existing convertible note hedge transactions and the existing warrant transactions and the 2028 convertible note exchanges, in each case as described below, are expected to close on May 18, 2026, subject to customary closing conditions.

Advanced Energy expects the net proceeds from the offering of the notes to be approximately $980.8 million (or approximately $1,128.1 million if the initial purchasers exercise their option to purchase the additional notes in full) after deducting the initial purchasers’ discounts and after deducting offering expenses payable by Advanced Energy.

Advanced Energy intends to use $60.0 million of the net proceeds from the offering to pay the cost of the capped call transactions it entered into in connection with the offering, as described below (or $69.0 million if the initial purchasers exercise their option to purchase additional notes in full). In addition, Advanced Energy expects to pay approximately $442.4 million of the net proceeds from the offering and to issue approximately 1.98 million shares of its common stock, collectively, in exchange for approximately $438.3 million aggregate principal amount of its previously issued 2.50% Senior Convertible Notes due 2028 (the “2028 convertible notes”), as described below. Advanced Energy intends to use the remainder of the net proceeds from the offering for general corporate purposes, including potential retirement of the remaining 2028 convertible notes. If the initial purchasers exercise their option to purchase additional notes, Advanced Energy expects to enter into additional capped call transactions with the option counterparties and use the remaining proceeds for general corporate purposes.

The notes will be Advanced Energy’s senior unsecured obligations and will rank senior in right of payment to any of its indebtedness that is expressly subordinated in right of payment to the notes; equal in right of payment to any of its indebtedness that is not so subordinated, including the 2028 convertible notes; effectively junior in right of payment to


any of its secured indebtedness to the extent of the value of the assets securing such indebtedness; and structurally junior to all indebtedness and other liabilities (including trade payables) of its subsidiaries. The notes will not bear regular interest, and the principal amount of the notes will not accrete. The notes will mature on May 15, 2031, unless earlier converted, redeemed or repurchased. The initial conversion rate is 1.9655 shares of common stock per $1,000 principal amount of notes, which is equivalent to an initial conversion price of approximately $508.78 per share, representing a premium of approximately 50% over the closing price of the common stock of $339.19 per share on May 13, 2026. Advanced Energy will satisfy any conversion elections by paying cash up to the aggregate principal amount of the notes to be converted, and paying or delivering, as the case may be, cash, shares of common stock or a combination of cash and shares of common stock, at Advanced Energy’s election, in respect of the remainder, if any, of its conversion obligation in excess of the aggregate principal amount of the notes to be converted.

Advanced Energy may redeem for cash all or any portion of the notes, at its option, on or after May 21, 2029 if the last reported sale price of Advanced Energy’s common stock has been at least 130% of the conversion price then in effect for at least 20 trading days (whether or not consecutive) during any 30 consecutive trading-day period (including the last trading day of such period) ending on, and including, the trading day immediately preceding the date on which Advanced Energy provides the related notice of redemption. In addition, Advanced Energy may redeem for cash all, but not less than all, of the notes at any time if the amount of the notes that remains outstanding is less than 25% of the aggregate principal amount of the notes initially issued under the indenture, subject to certain conditions described in the indenture. The redemption price for any such redemption will be 100% of the principal amount of the notes to be redeemed, plus accrued and unpaid special interest, if any, to, but excluding, the relevant redemption date. No sinking fund is provided for the notes. If Advanced Energy undergoes a fundamental change (as defined in the indenture governing the notes), holders may require Advanced Energy to repurchase for cash all or part of their notes at a repurchase price equal to 100% of the principal amount of the notes to be repurchased, plus accrued and unpaid special interest, if any, to, but excluding, the fundamental change repurchase date.

In connection with the pricing of the notes, Advanced Energy has entered into privately negotiated capped call transactions with certain of the initial purchasers or their respective affiliates and certain other financial institutions (the “option counterparties”). The capped call transactions will cover, subject to anti-dilution adjustments substantially similar to those applicable to the notes, the same number of shares of common stock initially underlying the notes. The capped call transactions are expected generally to reduce potential dilution to Advanced Energy’s common stock upon any conversion of notes and/or offset any cash payments Advanced Energy is required to make in excess of the principal amount of converted notes, as the case may be, with such reduction and/or offset subject to a cap.

The cap price of the capped call transactions will initially be $678.38 per share, which represents a premium of 100.0% over the last reported sale price of Advanced Energy’s common stock of $339.19 per share on May 13, 2026, and is subject to certain adjustments under the terms of the capped call transactions.


In connection with establishing their initial hedges of the capped call transactions, the option counterparties or their respective affiliates have entered into or will enter into various derivative transactions with respect to the common stock. This activity could increase (or reduce the size of any decrease in) the market price of the common stock or the notes at that time. In addition, the option counterparties or their respective affiliates may modify their hedge positions by entering into or unwinding various derivatives with respect to the common stock and/or purchasing or selling the common stock or other securities of Advanced Energy in secondary market transactions prior to the maturity of the notes (and are likely to do so (x) during any observation period related to a conversion of notes or following any repurchase of notes in connection with any fundamental change, optional redemption or cleanup redemption and (y) following any other repurchase of notes if Advanced Energy elects to unwind a portion of the capped call transactions in connection with such repurchase). This activity could also cause or avoid an increase or a decrease in the market price of the common stock or the notes, which could affect holders’ ability to convert the notes and, to the extent the activity occurs during any observation period related to a conversion of notes, it could also affect the amount and value of the consideration that holders will receive upon conversion of the notes.

Contemporaneously with the pricing of the notes in the offering, Advanced Energy entered into certain separate and individually negotiated transactions with certain holders of the 2028 convertible notes to exchange approximately $438.3 million aggregate principal amount of the 2028 convertible notes for approximately $442.4 million in cash and approximately 1.98 million shares of Advanced Energy’s common stock on terms that were negotiated separately with each holder (each, a “note exchange” and collectively, the “2028 convertible note exchanges”). The terms of each note exchange depended on several factors, including the market price of Advanced Energy’s common stock and the trading price of the 2028 convertible notes at the time of each such note exchange. Advanced Energy expects that holders of the 2028 convertible notes that exchange their 2028 convertible notes may enter into or unwind various derivatives with respect to Advanced Energy’s common stock (including entering into derivatives with one or more of the initial purchasers in the offering or their respective affiliates) and/or purchase or sell shares of Advanced Energy’s common stock concurrently with or shortly after the pricing of the notes. This activity could affect the market price of Advanced Energy’s common stock.

In connection with the issuance of the 2028 convertible notes, Advanced Energy entered into convertible note hedge transactions (the “existing convertible note hedge transactions”) with certain financial institutions (the “existing counterparties”). Advanced Energy also entered into separate warrant transactions (the “existing warrant transactions”) with the existing counterparties. In connection with the 2028 convertible note exchanges, Advanced Energy entered into agreements with the existing counterparties to unwind a portion of: (i) the existing convertible note hedge transactions in a notional amount corresponding to the principal amount of the 2028 convertible notes exchanged and (ii) the existing warrant transactions with respect to a number of shares equal to the notional shares underlying such 2028 convertible notes exchanged. In connection with such terminations and the related unwinding of the existing hedge position of the existing counterparties with respect to such transactions, such existing counterparties and/or their respective affiliates may sell shares of Advanced Energy’s common stock in secondary market transactions and/or enter into or unwind various derivative transactions with respect to Advanced Energy’s common stock concurrently with or shortly after the pricing


of the notes. This activity could affect the market price of Advanced Energy’s common stock. In connection with such terminations, Advanced Energy anticipates that it will receive on a net basis from the existing counterparties an aggregate of approximately $44.6 million.

The exchange of the 2028 convertible notes and the unwind of the existing convertible note hedge transactions and the existing warrant transactions, and the potential related market activities by holders of the 2028 convertible notes participating in the 2028 convertible note exchanges and the existing counterparties, as applicable, could increase (or reduce the size of any decrease in) or decrease (or reduce the size of any increase in) the market price of Advanced Energy’s common stock, which may affect the trading price of the notes in the offering at that time. Advanced Energy cannot predict the magnitude of such market activity or the overall effect it will have on the price of the notes in the offering or Advanced Energy’s common stock.

The notes and any shares of the common stock issuable upon conversion of the notes have not been registered under the Securities Act or under any U.S. state securities laws or in any other jurisdiction and may not be offered or sold in the United States absent registration or an applicable exemption from registration requirements.

This press release is neither an offer to sell nor a solicitation of an offer to buy any of these securities nor shall there be any sale of these securities in any state or jurisdiction in which such an offer, solicitation or sale would be unlawful prior to the registration or qualification under the securities laws of any such state or jurisdiction. This press release does not constitute an offer to purchase or notice of redemption with respect to the 2028 convertible notes, and Advanced Energy reserves the right to elect not to proceed with the 2028 convertible note exchanges.

How much cash will Advanced Energy (AEIS) receive from the new convertible notes?

Advanced Energy expects net proceeds of approximately $980.8 million from the base $1.0 billion offering, or about $1,128.1 million if the initial purchasers exercise their $150 million option in full, after deducting discounts and offering expenses associated with the 0% Convertible Senior Notes.

Advanced Energy plans to spend about $60.0 million on capped call transactions, pay roughly $442.4 million in cash and issue about 1.98 million shares to exchange $438.3 million of 2028 convertible notes, and use remaining funds for general corporate purposes, including potentially retiring remaining 2028 notes.

What are the key conversion terms of Advanced Energy’s new 0% notes?

Each $1,000 principal amount of notes initially converts into 1.9655 shares, implying a conversion price around $508.78 per share. This represents a 50% premium over Advanced Energy’s $339.19 common stock closing price on May 13, 2026, the reference date used for the transaction pricing.
