On March 7, 2016, ISP II transferred to ISP II Co-Invest 403,711shares of Common Stock and ISP II-B transferred to ISP II Co-Invest 317,365 shares of Common Stock, in each case, pursuant to that certain Stock Transfer Agreement, dated as of March 7, 2016, by and among ISP II, ISP II-B and ISP II Co-Invest (the “ISP II Co-Invest Transfer Agreement”). The Common Stock was acquired for $5.9435 per share.

On February 27, 2017, the Issuer effected a 2-to-1 reverse stock split of its outstanding capital stock. Also on February 27, 2017, the Issuer amended and restated its certificate of incorporation, in part implementing a dual class common stock structure where all existing shares of Common Stock converted to Class B Common Stock and the Issuer authorized a new class of Class A Common Stock. The Class A Common Stock is entitled to one vote per share and the Class B Common Stock is entitled to ten votes per share.

Immediately prior to the completion of the Issuer’s initial public offering on March 29, 2017 (the “IPO Closing Date”), all outstanding shares of Series C Preferred Stock were automatically converted into shares of the Issuer’s Class B Common Stock, par value $0.0001 per share, of the Company (the “Class B Common Stock”) resulting in ISP II holding 907,480 shares of Class B Common Stock, ISP II-B holding 710,373 of Class B Common Stock, and ISP II Co-Invest holding 1,053,132 of Class B Common Stock.

The source of funds for this consideration was the available capital of each of ISP II and ISP II-B, which represents capital contributions from investors in each of ISP II and ISP II-B, respectively.

Immediately following the closing of the Company’s initial public offering, ISP II directly owned 378,618 shares of Class A Common Stock and 907,480 shares of Class B Common Stock, ISP II-B directly owned 296,382 shares of Class A Common Stock and 710,373 shares of Class B Common Stock and ISP II Co-Invest directly owned 1,053,132 shares of Class B Common Stock.

Each of ISP II, ISP II-B and ISP II Co-Invest acquired the shares of Common Stock for investment in the ordinary course of business, as it believed that such shares represented an attractive investment opportunity. As described in Item 3, each of ISP II, ISP II-B and ISP II Co-Invest initially invested in the Company prior to the Company’s initial public offering. Greg Stanger is a non-voting observer on the Company’s Board of Directors and is a partner of ICONIQ GP II, the general partner of each of ISP II, ISP II-B and ISP II Co-Invest.

As noted above, each of ISP II, ISP II-B and ISP II Co-Invest acquired the Common Stock as investments in its ordinary course of business.
