Record Dates		April 15 and October 15.
Last Reported Sale Price per Share of Class A Common Stock on NYSE on April 30, 2025		$21.14.
Conversion Premium		Approximately 35.0% above the Public Offering Price per Share of Class A Common Stock in the Concurrent Delta Offering (as defined below).
Public Offering Price per Share of Class Common Stock in the Concurrent Delta Offering		$19.55 per share of Class A common stock.
Initial Conversion Price		Approximately $26.39 per share of our Class A common stock.
Initial Conversion Rate		37.8896 shares of our Class A common stock per $1,000 principal amount of Notes.
Optional Redemption		The Notes will be redeemable, in whole or in part (subject to certain limitations described below), at our option at any time, and from time to time, on or after May 1, 2028 and on or before the 25th scheduled trading day immediately before the maturity date, at a cash redemption price equal to the principal amount of the Notes to be redeemed, plus accrued and unpaid interest, if any, to, but excluding, the redemption date, but only if the last reported sale price per share of our Class A common stock exceeds 130% of the conversion price on (1) each of at least 20 trading days, whether or not consecutive, during the 30 consecutive trading days ending on, and including, the trading day immediately before the date we send the related redemption notice; and (2) the trading day immediately before the date we send such notice. However, we may not redeem less than all of the outstanding Notes unless at least $100.0 million aggregate principal amount of Notes are outstanding and not called for redemption as of the time we send the related redemption notice. In addition, calling any Note for redemption will constitute a make-whole fundamental change with respect to that Note, in which case the conversion rate applicable to the conversion of that Note will be increased in certain circumstances if it is converted after it is called for redemption. See “Description of Notes—Optional Redemption” in the Preliminary Prospectus Supplement.

Use of Proceeds		We estimate that the net proceeds to us from this offering will be approximately $129.0 million (or approximately $148.4 million if the underwriters fully exercise their option to purchase additional Notes), after deducting the underwriting discounts and commissions and our estimated offering expenses. We expect to use the net proceeds to purchase from Solaris LLC, our operating subsidiary, a subordinated convertible note to be issued by Solaris LLC with substantially similar economic terms as the Notes, and Solaris LLC expects to use such net proceeds to fund growth capital for additional power generation equipment, including new natural gas turbines and complementary “balance of plant” electrical equipment, to support customer activity. See “Use of Proceeds” in the Preliminary Prospectus Supplement.
Concurrent Delta Offering		Concurrently with this offering, Morgan Stanley & Co. LLC and Santander US Capital Markets LLC, each acting severally on behalf of itself and/or its affiliates (in such capacity, the “delta offering underwriters”), are offering, in a separate, underwritten public offering pursuant to a prospectus supplement that we have filed with the Securities and Exchange Commission, 1,193,521 shares of our Class A common stock at a public offering price of $19.55 per share, to facilitate hedging transactions by certain investors (the “convertible arbitrage investors”) subscribing for the Notes. The number of shares of our Class A common stock subject to the Concurrent Delta Offering is expected to generally correspond to the initial short positions of convertible arbitrage investors being established to hedge their market risk with respect to the Notes they acquire. We have been advised that the shares sold by the delta offering underwriters in the Concurrent Delta Offering will be borrowed from third parties, and will be: (x) purchased by a delta offering underwriter from certain convertible arbitrage investors who have sold them short to such delta offering underwriter in connection with the offering of the Notes, and/or (y) sold short by the delta offering underwriters to facilitate concurrent privately negotiated transactions between one of the delta offering underwriters with certain convertible arbitrage investors seeking a short exposure to our Class A common stock through a derivative, in an equal notional amount. No new shares of our Class A common stock will be issued for the Concurrent Delta Offering. The Concurrent Delta Offering and the offering of the Notes are contingent upon one another. We will not receive any proceeds from the Concurrent Delta Offering.

•

if the stock price is greater than $125.00 (subject to adjustment in the same manner as the stock prices set forth in the column headings of the table above are adjusted, as described in the Preliminary Prospectus Supplement under the caption “Description of Notes—

Notwithstanding anything to the contrary, in no event will the conversion rate be increased to an amount that exceeds 51.1508 shares of our Class A common stock per $1,000 principal amount of Notes, which amount is subject to adjustment in the same manner as, and at the same time and for the same events for which, the conversion rate is required to be adjusted pursuant to the provisions described in the Preliminary Prospectus Supplement under the caption “Description of Notes—Conversion Rights—Conversion Rate Adjustments—Generally.”
