Item 1A. Risk Factors.

Our business is subject to a variety of risks and uncertainties that are difficult to predict and many of which are outside of our control. For a detailed discussion of the risks that affect our business, refer to Item 1A. Risk Factors of Part I of our 2023 Annual Report. As of the date of this filing, there have been no material changes to the risk factors previously described in our 2023 Annual Report. The matters specifically identified are not the only risks and uncertainties facing our company, and risks and uncertainties not known to us or not specifically identified also may impair our business operations. If any of these risks and uncertainties occur, our business, financial condition, results of operations and cash flows could be negatively affected, which could negatively impact the value of an investment in our company.

Unregistered Sales of Equity Securities

On April 18, 2024 and May 31, 2024, we completed acquisitions in which a portion of the consideration consisted of the unregistered issuance of shares of our common stock. The aggregate consideration for these acquisitions included 35,886 shares of our common stock, valued at $9.1 million as of the acquisition dates. Additionally, subsequent to June 30, 2024, we completed an acquisition on July 17, 2024, in which a portion of the consideration for the acquisition consisted of the unregistered issuance of shares of our common stock. The aggregate consideration paid at closing in this acquisition included 882,926 shares of our common stock.

The shares of common stock issued in these transactions were issued in reliance upon the exemption from registration provided by Section 4(a)(2) of the Securities Act of 1933, as amended, as the shares were issued to the owners of the businesses acquired in privately negotiated transactions not involving any public offering or solicitation.
