INTRODUCTORY NOTE

As previously reported in the Current Report on Form 8-K filed on January 27, 2025, with the U.S. Securities and Exchange Commission (the “SEC”), Aspen Technology, Inc., a Delaware corporation (the “Company”), entered into an Agreement and Plan of Merger, dated as of January 26, 2025 (the “Merger Agreement”), with Emerson Electric Co., a Missouri corporation (“Parent”) and Emersub CXV, Inc., a Delaware corporation and a wholly owned subsidiary of Parent (“Purchaser”). All capitalized terms used herein and not otherwise defined have the meanings given to such terms in the Merger Agreement.

Pursuant to the Merger Agreement, on February 10, 2025, Purchaser commenced a cash tender offer (the “Offer”) to purchase all of the outstanding shares of common stock of the Company, par value $0.0001 per share (the “Shares”), at a price of $265.00 per share (the “Offer Price”), net to the seller in cash, without interest, and subject to any withholding of taxes, upon the terms and subject to the conditions set forth in the Merger Agreement.

At 5:00 p.m., Eastern Time, on March 11, 2025 (the “Expiration Time”), the Offer expired and was not further extended. Equiniti Trust Company, LLC (“Equiniti”), the depository and paying agent for the Offer, advised Purchaser that, as of the Expiration Time, a total of 19,479,909 Shares (including 1,859,751 Shares tendered in the Offer that have not yet been “received” by the “depository,” as such terms are defined in Section 251(h)(6) of the General Corporation Law of the State of Delaware (the “DGCL”)) were validly tendered and not properly withdrawn pursuant to the Offer, representing approximately 72% of the Shares issued and outstanding as of the expiration of the Offer, excluding, for the purposes of calculating the total number of Shares outstanding, Shares owned by Parent and its subsidiaries, Parent’s and its subsidiaries’ directors and officers, and the Company’s directors and officers. The number of Shares tendered satisfied the Unaffiliated Tender Condition (as defined in the Merger Agreement). As the Unaffiliated Tender Condition and each of the other conditions of the Offer were satisfied, on March 11, 2025, Purchaser accepted for payment the Shares that were validly tendered and not properly withdrawn pursuant to the Offer prior to the Expiration Time. Parent has transmitted payment for such Shares to Equiniti, which will disburse the Offer Price to tendering Company stockholders whose Shares have been accepted for payment in accordance with the terms of the Offer.

Following consummation of the Offer, on March 12, 2025, Parent completed its acquisition of the Company pursuant to the terms of the Merger Agreement through the merger of Purchaser with and into the Company, and without a meeting of stockholders of the Company in accordance with Section 251(h) of the DGCL, with the Company surviving as a wholly owned subsidiary of Parent (the “Merger”).

In the Merger, each Share issued and outstanding immediately prior to the effective time of the Merger (the “Effective Time”) that was not tendered and accepted pursuant to the Offer (other than Shares held by the Company, Parent, Purchaser, or any of their respective wholly owned subsidiaries and Shares as to which appraisal rights have been properly exercised and perfected in accordance with applicable law) was canceled and converted into the right to receive the Offer Price in cash, without interest, and subject to any withholding of taxes. At the Effective Time, each outstanding and unexercised Company stock option, whether vested or unvested, that had an exercise price less than the Offer Price was automatically canceled and converted into the right to receive (without interest) an amount in cash, subject to applicable withholding, equal to the product of (i) the excess of the Offer Price over the applicable exercise price and (ii) the total number of Shares subject to such Company stock option as of immediately prior to the Effective Time. At the Effective Time, each Company stock option that had an exercise price equal to or greater than the Offer Price was canceled for no consideration. At the Effective Time, each Company restricted stock unit and performance stock unit (a) that vested (and, in the case of a Company performance stock unit, was earned) at or prior to the Effective Time or (b) that was held by a non-employee director of the Company (whether vested or unvested), was automatically canceled and converted into the right to receive (without interest) an amount in cash, subject to applicable withholding equal to the product of (i) the Offer Price and (ii) the total number of Shares subject to such Company restricted stock unit or performance stock unit as of immediately prior to the Effective Time. At the Effective Time, each other Company restricted stock unit and performance stock unit that was outstanding and unvested as of immediately prior to the Effective Time and held by a continuing employee of the Company or an actively engaged non-employee consultant of the Company was assumed by Parent and converted into an award of Parent restricted stock units with respect to shares of Parent. The number of shares of Parent applicable to each such Parent restricted stock unit is equal to the product of (a) the number of Shares underlying such Company restricted stock unit or performance stock unit immediately prior to the Effective Time (in the case of Company performance stock units, based on target performance) and (b) the Equity Award Exchange Ratio (as defined in the Merger Agreement), rounded down to the nearest whole number of shares of Parent. Each Parent restricted stock unit shall be subject to the same terms and conditions (including vesting schedule, other than performance-based vesting conditions) as applied to the corresponding Company restricted stock unit or performance stock unit immediately prior to the Effective Time.

The foregoing description of the Offer, the Merger and the Merger Agreement is not complete and is qualified in its entirety by reference to the Merger Agreement, a copy of which was filed as Exhibit 2.1 to the Company’s Current Report on Form 8-K, filed with the SEC on January 27, 2025, and is incorporated herein by reference.
