Item 1.01. Entry into a Material Definitive Agreement.

On December 16, 2021, Stem, Inc., a Delaware corporation (the “Company”), entered into a Stock Purchase Agreement (the “Purchase Agreement”) with the selling stockholders of AlsoEnergy, Inc., a Delaware corporation (“AlsoEnergy”), as identified in the Purchase Agreement (the “Selling Stockholders”), and Robert Schaefer and Clairvest GP Manageco Inc., as representatives of the Selling Stockholders (the “Sellers’ Representatives”). The Purchase Agreement provides that, upon the terms and subject to the conditions thereof, the Company will acquire, on a cash-free, debt free basis, all of the outstanding shares of capital stock of AlsoEnergy for an aggregate purchase price of $695.0 million, consisting of approximately 75% in cash (the “Cash Consideration”) and approximately 25% in shares of the Company’s common stock, par value $0.0001 per share (the “Share Consideration”). The Cash Consideration is subject to customary working capital adjustments.

The Purchase Agreement contains customary representations, warranties and covenants of the parties.

Each party’s obligation to consummate the transactions contemplated by the Purchase Agreement is subject to customary closing conditions, including the expiration or termination of any applicable waiting period under the Hart-Scott-Rodino Antitrust Improvements Act of 1976. The transaction is anticipated to close in the first quarter of 2022, subject to the satisfaction or waiver of such customary closing conditions.

The Purchase Agreement contains certain rights to terminate the agreement, including the right of either the Company or the Sellers’ Representatives to terminate the Purchase Agreement (i) on or after June 15, 2022, if the transactions contemplated by the Purchase Agreement have not been consummated by such date, or (ii) in the event of certain uncured material breaches of the Purchase Agreement by the other party or parties.

The Company intends to issue the Share Consideration in reliance upon the exemption from registration under the Securities Act of 1933, as amended, provided by Section 4(a)(2) thereof for transactions not involving a public offering and the safe harbor afforded by Rule 506 thereunder, and has agreed to file a Registration Statement covering the resale of the Share Consideration by the recipients.

The foregoing description of the Purchase Agreement and the transactions contemplated thereby does not purport to be complete and is qualified in its entirety by reference to the full text of the Purchase Agreement, which will be filed as an exhibit to the Company’s Annual Report on Form 10-K for the fiscal year ending December 31, 2021.

The Purchase Agreement has been attached as an exhibit to this report in order to provide investors and security holders with information regarding its terms. It is not intended to provide any other factual information about the Company, AlsoEnergy, or their respective subsidiaries and affiliates. The representations, warranties and covenants contained in the Purchase Agreement were made only for purposes of that agreement and as of specific dates as set forth therein; are solely for the benefit of the parties to the Purchase Agreement; may be subject to limitations agreed upon by the parties, including being qualified by confidential disclosures exchanged between the parties in connection with the execution of the Purchase Agreement; may have been made for the purposes of allocating contractual risk between the parties to the Purchase Agreement instead of establishing these matters as facts; and may be subject to standards of materiality applicable to the parties that differ from those applicable to investors. Investors should not rely on the representations, warranties or covenants or any description thereof as characterizations of the actual state of facts or condition of the Company, AlsoEnergy or their respective subsidiaries and affiliates. Moreover, information concerning the subject matter of the representations, warranties and covenants may change after the date of the Purchase Agreement, which subsequent information may or may not be fully reflected in public disclosures by the Company.
