Use of proceeds

We estimate that the net proceeds to us from this offering will be approximately $180.4 million, or $208.3 million if the underwriters exercise their option to
purchase additional shares in full, based assuming an initial public offering price of $52.00 per share, the midpoint of the estimated offering price range set forth on the cover page of this prospectus, and after deducting underwriting
discounts and commissions and estimated offering expenses payable by us.

Each $1.00 increase or decrease in the assumed initial public offering price of
$52.00 per share, the midpoint of the estimated offering price range set forth on the cover page of this prospectus, would increase or decrease, as applicable, net proceeds to us by $3.6 million, assuming that the number of shares offered
by us as set forth on the cover page of this prospectus remains the same, and after deducting underwriting discounts and commissions and estimated offering expenses payable by us. Similarly, each increase or decrease of 1.0 million shares
offered by us would increase or decrease, as applicable, net proceeds to us by approximately $48.4 million, assuming an initial public offering price of $52.00 per share, the midpoint of the estimated offering price range set forth on the
cover page of this prospectus, and after deducting underwriting discounts and commissions and estimated offering expenses payable by us.

The principal purposes
of this offering are to increase our financial flexibility, increase our visibility in the marketplace, and create a public market for our Class A common stock. We currently intend to use the net proceeds from this offering, together with our
existing cash and cash equivalents, for working capital and other general corporate purposes, including to fund our growth, research and development initiatives, technology development, working capital, and operating expenses. However, we do not
currently have specific planned uses for the proceeds.

We may also use a portion of our net proceeds to acquire or invest in complementary products, technologies,
or businesses. However, we currently have no agreements or commitments to complete any such transactions.

Our expected use of the net proceeds from this offering
represents our intentions based upon our current plans and business conditions, which could change in the future as our plans and business conditions evolve. As of the date of this prospectus
