Our Class A Common Stock is listed on The New York Stock Exchange (the “NYSE”) under the symbol “ALIT.” On November 15, 2022, the last sale price of our Class A Common Stock as reported on the NYSE was $8.76 per share.

This prospectus supplement updates and supplements the information in the Prospectus and is not complete without, and may not be delivered or utilized except in combination with, the Prospectus, including any amendments or supplements thereto. This prospectus supplement should be read in conjunction with the Prospectus and if there is any inconsistency between the information in the Prospectus and this prospectus supplement, you should rely on the information in this prospectus supplement.
