Stem, Inc. Announces Pricing of Upsized Offering of $200 Million 4.25% Green Convertible Senior Notes Due 2030

Stem, Inc. ("Stem") (NYSE: STEM) announced today the pricing of $200 million aggregate principal amount of 4.25% Green Convertible Senior Notes due 2030 (the "Notes") in a private offering (the "Offering"), which was upsized from the previously announced $175 million offering, to persons reasonably believed to be qualified institutional buyers pursuant to Rule 144A under the Securities Act of 1933, as amended (the "Securities Act"). In connection with the Offering, Stem has granted the initial purchasers of the Notes an option to purchase, for settlement within a 13-day period from, and including, the date when the Notes are first issued, up to an additional $40 million aggregate principal amount of the Notes on the same terms and conditions. The sale of the Notes to the initial purchasers is expected to settle on April 3, 2023, subject to customary closing conditions.

When issued, the Notes will be senior, unsecured obligations of Stem. The Notes will accrue interest payable semi-annually in arrears and will mature on April 1, 2030, unless earlier repurchased, redeemed or converted in accordance with their terms prior to such date. The Notes will be convertible based on an initial conversion rate of 140.3066 shares of Stem's common stock per $1,000 principal amount of Notes (equivalent to an initial conversion price of approximately $7.13 per share of common stock, which represents a conversion premium of approximately 27.50% to the last reported sale price of Stem's common stock on The New York Stock Exchange (the "NYSE") on March 29, 2023). The Notes will be convertible upon the satisfaction of specified conditions into cash, shares of common stock of Stem or a combination thereof, with the form of consideration to be determined at Stem's election. The Notes will be redeemable, in whole or in part, for cash at Stem's option at any time, and from time to time, on or after April 5, 2027 and before the 45th scheduled trading day immediately before the maturity date, but only if the last reported sale price per share of Stem's common stock exceeds 130% of the conversion price for a specified period of time.

In connection with the pricing of the Notes, Stem has entered into privately negotiated capped call transactions with one or more of the initial purchasers or their affiliates and/or other financial institutions (the “option counterparties”). The capped call transactions are expected generally to reduce potential dilution to Stem’s common stock upon any conversion of the Notes and/or offset any potential cash payments Stem 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 is initially $11.18 per share of common stock, which represents a premium of 100.0% to the last reported sale price of Stem’s common stock on the NYSE on March 29, 2023, 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, Stem expects that the option counterparties or their respective affiliates will purchase shares of Stem’s common stock and/or enter into various derivative transactions with respect to Stem’s common stock concurrently with or shortly after the pricing of the Notes. This activity could increase (or reduce the size of any decrease in) the market price of Stem’s 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 Stem’s common stock and/or purchasing or selling Stem’s common stock or selling Stem’s common stock or other securities in secondary market transactions following the pricing of the Notes and prior to the maturity of the Notes (and are likely to do so following any dates the Notes are converted, repurchase or redeemed, if Stem exercises its option to terminate the relevant portion of the capped call transactions). This activity could also cause or avoid an increase or decrease in the market price of Stem’s common stock or the Notes, which could affect noteholders’ ability to convert the Notes and, to the extent the activity occurs during any observation period related to a conversion of Notes, it could affect the number of shares and value of the consideration that noteholders receive upon conversion of the Notes.

Stem intends to use (i) approximately $99.8 million of the net proceeds from the Offering to purchase and surrender for cancellation approximately $163.0 million aggregate principal amount of Stem's 0.50% Green Convertible Senior Notes due 2028 (the "2028 Notes") in privately negotiated transactions concurrently with the pricing of the Offering; (ii) approximately $23.2 million of the net proceeds of the Offering to fund the cost of entering into the capped call transactions described above; and (iii) the remainder of the net proceeds of the Offering for general corporate purposes. If the initial purchasers exercise their option to purchase additional Notes, then Stem intends to use a portion of the additional net proceeds to fund the cost of entering into additional capped call transactions as described above.

Stem intends to allocate an amount of funds equivalent to the net proceeds of the Offering towards financing or refinancing, in whole or in part, existing, new or ongoing Eligible Green Expenditures. "Eligible Green Expenditures" may include investments related to creating a more resilient clean energy system, optimized software capabilities for energy systems, and reducing waste through operations, including research, development, acquisitions, capital expenditures, and operational expenses in initiatives aligned with the Eligible Green Expenditures.

Stem expects that some purchasers of the Notes may seek to sell shares of Stem's common stock and/or enter into various derivative transactions to establish hedge positions with respect to the Notes. In addition, holders of the 2028 Notes that are repurchased in the concurrent repurchases described above may unwind or enter into various derivative transactions with respect to Stem's common stock and/or purchase shares of Stem's common stock in the open market to unwind any hedge positions they may have with respect to the 2028 Notes.

The Notes were offered only to persons reasonably believed to be qualified institutional buyers pursuant to Rule 144A under the Securities Act. The offer and sale of the Notes and any shares of common stock of Stem issuable upon conversion of the Notes, if any, have not been, and will not be, registered under the Securities Act or the securities laws of any other jurisdiction, and unless so registered, the Notes and such shares, if any, may not be offered or sold in the United States except pursuant to an applicable exemption from such registration requirements.

This press release does not constitute an offer to sell or a solicitation of an offer to buy, nor shall there be any offer or sale of, the Notes (or any shares of common stock of Stem issuable upon conversion of the Notes) in any state or jurisdiction in which the offer, solicitation, or sale would be unlawful prior to the registration or qualification thereof under the securities laws of any such state or jurisdiction.
