TB Partners XI is the general partner of each of TB Fund XI, TB Fund XI-A, TB Exec Fund XI, TB SOF II and TB SOF II-A. TB Partners XII is the general partner of each of TB Fund XII, TB Fund XII-A, TB Exec Fund XII and TB Exec Fund XII-A. TB, LLC is the ultimate general partner of each of TB Partners XI and TB Partners XII. In those capacities, TB Partners XI, TB Partners XII and TB, LLC may be deemed to share voting and dispositive power with respect to the Common Stock directly held by the other Reporting Persons. Each of TB Partners XI, TB Partners XII and TB, LLC disclaims beneficial ownership of the shares of Common Stock owned by the Reporting Persons except to the extent of its pecuniary interest therein.

Certain of the Reporting Persons, and certain affiliates of Silver Lake Group, L.L.C. listed on Annex A hereto (collectively, the “Stockholders”) are parties to a Stockholders’ Agreement (the “Stockholders’ Agreement”), which contains, among other things, certain provisions relating to transfer of, and coordination of the voting of, securities of the Issuer by the parties thereto.

By virtue of the Stockholder Agreement and the obligations and rights thereunder, certain of the Reporting Persons acknowledge and agree that they are acting as a “group” with the other Stockholders within the meaning of Section 13(d) of the Securities Exchange Act of 1934, as amended (the “Exchange Act”). Based in part on information provided by or on behalf of such other Stockholders, as of December 31, 2021, such a “group” would be deemed to beneficially own an aggregate of 111,564,512 shares of Common Stock, or 70.1% of the Common Stock of the Issuer. Pursuant to an amendment to the Stockholders Agreement, certain co-investors of the Reporting Persons who had previously been parties thereto are no longer parties to such agreement and therefore no longer members of the “group” previously described in Amendment No. 2 to Schedule 13G filed by the Reporting Persons on February 12, 2021. The Reporting Persons expressly disclaim beneficial ownership over any shares of Common Stock that they may be deemed to beneficially own solely by reason of the Stockholder Agreement. Certain entities affiliated with Silver Lake Group, L.L.C. are separately making Schedule 13G filings reporting their beneficial ownership of shares of Common Stock.

CUSIP No. 83417Q105

(b) Percent of class: In the aggregate, the Reporting Persons beneficially own 50,090,643 shares of Common Stock, or 31.5% of the total number of shares outstanding.

All percentages calculated in this Schedule 13G are based upon an aggregate of 159,090,194 shares of common stock outstanding as reported in the Issuer’s Quarterly Report on Form 10-Q as filed with the Commission on November 9, 2021.

(iv) shared power to dispose or to direct the disposition of: See Item 8 on the cover pages hereto.

The Reporting Persons expressly disclaim that they have agreed to act as a group other than as described in this Schedule 13G.
