Properties, in its own words

Our corporate headquarters are located in Troy, Michigan. We own our corporate headquarters facility, and an undeveloped parcel of land adjacent to our headquarters, which we may develop over the next few years.

We lease or sublease all of our other domestic and international offices. We expect to add facilities as we grow our employee base and expand geographically. We do not manage our facilities by segment because they may be used for multiple purposes, such as administration, sales, and development. We believe that our facilities are adequate to meet our needs for the immediate future, and that, should it be needed, suitable additional space will be available to accommodate expansion of our operations.

Risk factors and legal proceedings

The risks Altair Engineering Inc. names in Item 1A of its 10-K filed Feb 20, 2025: 71 risks under these headings, as written.⁵

• Risks associated with the pending transaction with Siemens
• The pending transaction with Siemens may be delayed or not occur at all for a variety of reasons, including that the Merger Agreement is terminated, and the failure to complete the Merger could adversely affect our business, results of operations, financial condition, and the market price of our common stock.
• Efforts to complete the Merger could disrupt our relationships with third parties and employees, divert management’s attention, or result in negative publicity or legal proceedings, any of which could negatively impact our operating results and ongoing business.
• Since our stockholders have approved the Merger Agreement, the Merger Agreement now precludes us from pursuing alternative transactions to the Merger.
• While the Merger Agreement is in effect, we are subject to restrictions on our business activities.
• Litigation has arisen, and more could arise, in connection with the Merger; such litigation against Altair could result in substantial costs, an injunction preventing the completion of the Merger and/or a judgment resulting in the payment of damages.
• Risks relating to our business and industry
• We have experienced significant revenue growth and we may fail to sustain that growth rate or may not grow in the future.
• If we cannot maintain our company culture of innovation, teamwork, and communication, our business may be harmed.
• If our existing customers or users do not increase their usage of our software, or we do not add new customers, the growth of our business may be harmed.
• Our ability to acquire new customers is difficult to predict because our software sales cycle can be long.
• Reduced spending on product design and development activities by our customers may negatively affect our revenues.

Legal proceedings

Securities class action lawsuits and derivative lawsuits are often brought against public companies that have entered into merger agreements. Even if such lawsuits are unsuccessful, defending against these claims can result in substantial costs. Stockholders of Altair have filed, and may in the future file, lawsuits against Altair and/or the directors and officers of Altair in connection with the Merger. As of the date of this Annual Report on Form 10-K, three Lawsuits relating to the Merger have been filed: (i) Elstein v. Altair Engineering Inc., et al., Case No. 2025-211856-CB (i.e., the Elstein Lawsuit), which was filed in the State of Michigan Circuit Court for the Sixth Judicial Circuit, Oakland County, on January 3, 2025 and (ii) Jones v. Altair Engineering Inc., et al., Index No. 650098/2025 (i.e., the Jones Lawsuit) and Kent v. Altair Engineering Inc., et al., Index No. 650113/2025 (i.e., the Kent Lawsuit), both of which were filed in the Supreme Court of the State of New York, County of New York, on January 7, 2025 and January 8, 2025, respectively. The Elstein Lawsuit was filed by a purported stockholder of the Company as an individual action and alleges that the Proxy Statement was materially incomplete due to certain misrepresentations and omissions in violation of Michigan’s Uniform Securities Act and Michigan common law. The Elstein Lawsuit names as defendants the Company, its directors and Siemens Industry, and seeks, among other relief, an order enjoining the closing of the vote on the Merger. The Jones Lawsuit and the Kent Lawsuit were each filed by a purported stockholder of the Company as an individual action and allege that the Proxy Statement was materially incomplete due to certain misrepresentations and omissions in violation of New York common law. The Jones Lawsuit and Kent Lawsuit name as defendants the Company and its directors and seek, among other relief, an order enjoining the consummation of the Merger.
