In September 2021, the Company issued 2,935,564 shares of its Class A common stock in a private placement to Matrix Capital Management Company LP, for aggregate proceeds of $200.0 million. Per the terms of the agreement, the shares are subject to a one-year lockup period.

The securities issued in the private placement have not been registered under the Securities Act of 1933, as amended (the “Securities Act”), or any state or other applicable jurisdiction’s securities laws, and may not be offered or sold in the United States absent registration or an applicable exemption from the registration requirements of the Securities Act and applicable state or other jurisdictions’ securities laws. The Company has agreed to have a registration statement with the U.S. Securities and Exchange Commission (the “SEC”) registering the resale of the shares of common stock issued in the private placement declared or deemed effective by the SEC no later than the one-year anniversary after the closing of the private placement.

During the first quarter of 2021, the Company initiated a restructuring plan to realign resources with the Company’s current business outlook and cost structure. The restructuring plan resulted in charges for employee termination benefits of $(0.1) million and $5.0 million for the three and nine months ended September 30, 2021, respectively. The Company expects remaining costs will be immaterial, and all amounts will be paid in 2021. The restructuring costs are attributable primarily to the Software reportable segment.
