Item 2.02    Results of Operations and Financial Conditions.

Item 4.02 Non-Reliance on Previously Issued Financial Statements or a Related Audit Report or Completed Interim Review.

On November 3, 2026, Management, with the oversight of the Audit Committee of the Board of Directors (the “Audit Committee”), concluded that the Company’s previously issued unaudited condensed consolidated financial statements included in its Quarterly Reports on Form 10-Q for the periods ended March 31, 2026 and June 30, 2026, should no longer be relied upon due to misstatements that are described below and that the Company will restate such financial statements to make necessary corrections.

The non-reliance conclusion described above resulted from the identification of errors in the Company's calculation of revenue under the percent of completion method and accounting for software subscriptions.

The impacts of the restatement on net income are summarized below:

For the three months ended March 31, 2026: Net Income is $36.5 million representing a decrease of $3.4 million from the $39.8 million previously reported.

For the six months ended June 30, 2026: Net Income is $103.6 million, representing an increase of $7.1 million from the $96.5 million previously reported.

In connection with the restatements, the Company re-evaluated its conclusion regarding the effectiveness of the Company's disclosure controls and procedures and internal controls over financial reporting for the relevant periods and determined that a material weakness existed. The Company will report the material weakness in its Quarterly Report on Form 10-Q for the quarter ended September 30, 2026.

The Audit Committee has discussed the matters disclosed herein with Grant Thornton LLP, the Company's independent registered accounting firm.

Concurrently with the filing of this Current Report on Form 8-K, the Company is

All statements in the teleconference, other than historical financial information, may be deemed to be "forward-looking statements" within the meaning of the Private Securities Litigation Reform Act of 1995.

Item 7.01    Regulation FD Disclosure.

On February 28, 2022, the Company issued the press release described above in Item 2.02 of this Current Report on Form 8-K. A copy of the press release is attached hereto as Exhibit 99.1.

All statements in the teleconference, other than historical financial information, may be deemed “forward-looking statements” within the meaning of the Private Securities Litigation Reform Act of 1995. Words such as “expects”, “anticipates”, “intends”, “plans”, “believes”, “seeks”, “estimates”, “should”, “will”, and variations of such words and similar expressions are intended to identify such forward-looking statements. These statements are not guarantees of future performance and involve certain risks, uncertainties and assumptions, which are difficult to predict. Therefore, actual outcomes and results may differ materially from what is expressed or forecasted in such forward-looking statements. Participants and readers are cautioned not to place undue reliance on these forward-looking statements, which speak only as of the date on which they are made. We undertake no obligations to update publicly any forward-looking statements, whether as a result of new information, future events or otherwise. Important factors that could cause results to differ materially from those in the forward-looking statements include (1) the timing and extent of changes in raw material and component prices, (2) the effects of fluctuations in the commercial/industrial new construction market, (3) the timing and extent of changes in interest rates, as well as other competitive factors during the year, and (4) general economic, market or business conditions.

In accordance with General Instruction B.2 of Form 8-K, the information in this Item shall not
