SEC.gov | Request Rate Threshold Exceeded

U.S. Securities and Exchange Commission

You’ve Exceeded the SEC’s Traffic Limit

Your request rate has exceeded the SEC’s maximum allowable requests per second. Your access to SEC.gov will be limited for 10 minutes.

Current guidelines limit each user to a total of no more than 10 requests per second, regardless of the number of machines used to submit requests. To ensure that SEC.gov remains available to all users, we reserve the right to block IP addresses that submit excessive requests.

The block will be lifted automatically by waiting 10 minutes. Continuing to exceed the SEC’s maximum allowable request rate during the time-out period will extend the duration of the time-out period. To ensure fair access for all users, please reduce the rate of your requests and visit SEC.gov again after the 10 minute time-out period has passed.

In accordance with General Instruction B.2 of Form 8-K, the information in this Item 2.02 of this Current Report on Form 8-K, including Exhibit 99.1 attached hereto, shall not be deemed “filed” for the purposes of Section 18 of the Securities Exchange Act of 1934, as amended (the “Exchange Act”), or otherwise subject to the liabilities of that section, nor shall it be deemed incorporated by reference in any filing under the Securities Act of 1933, as amended, or the Exchange Act, except as shall be expressly set forth by specific reference in such a filing.

Item 8.01. Other Events.

On February 5, 2026, the Board of Directors of the Company approved a share repurchase program with an indefinite term under which the Company may purchase up to $500 million of its Class A common stock (the “2026 Share Repurchase Program”) once the Company's existing $300.0 million share repurchase program (the "2022 Share Repurchase Program") has been exhausted. As of February 5, 2026, $23.2 million remained available for repurchase pursuant to the 2022 Share Repurchase Program.

Pursuant to the 2026 Share Repurchase Program, the Company may repurchase its Class A common stock from time to time, in amounts, at prices and at such times as it deems appropriate, subject to market conditions and other considerations. The Company may make repurchases in the open market, through privately negotiated transactions, through accelerated repurchase programs (including through the use of derivatives), pursuant to Rule 10b5-1 plans or through enhanced open-market repurchases (eOMR). The 2026 Share Repurchase Program will be conducted in compliance with applicable legal requirements and shall be subject to market conditions and other factors.

The manner, timing and amount of any purchase will be based on an evaluation of market conditions, stock price and other factors. The 2026 Share Repurchase Program has no termination date, may be suspended, amended or discontinued at any time and does not obligate the Company to acquire any amount of Class A common stock.
