Item 7.01.    Regulation FD Disclosure.

On December 12, 2021, Luminar Technologies, Inc. (“Luminar”) announced that its Board of Directors has authorized a program to repurchase an amount of Class A common stock not to exceed the greater of $250 million and 50% of the aggregate principal amount of the notes (as defined below). The repurchase program does not have an expiration date. Under the repurchase program, Luminar may purchase shares of Class A common stock from time to time through open market repurchases, privately negotiated transactions or other means, including through Rule 10b5-1 trading plans or through the use of other techniques such as accelerated share repurchases. The timing and number of shares repurchased will depend on a variety of factors, including stock price, trading volume, and general business and market conditions. A copy of the press release announcing the common stock repurchase program is furnished hereto as Exhibit 99.1 and is incorporated herein by reference.

The information furnished with this Item 7.01, including Exhibit 99.1, shall not be deemed “filed” for purposes of Section 18 of the Securities Exchange Act of 1934, as amended (the “Exchange Act”), or incorporated by reference in any filing under the Securities Act of 1933, as amended (the “Securities Act”), or the Exchange Act, regardless of any general incorporation language in such filing.

Item 8.01.    Other events.

On December 14, 2021, Luminar announced its intention to offer, subject to market conditions and other factors, $500.0 million aggregate principal amount of convertible senior notes due 2026 (the “notes”) in a private offering (the “offering”) to persons reasonably believed to be qualified institutional buyers pursuant to Rule 144A under the Securities Act. In connection with the offering, Luminar also expects to grant the initial purchasers of the notes a 13-day period to purchase up to an additional $75.0 million aggregate principal amount of the notes.

Luminar intends to use a portion of the net proceeds from the offering for general corporate purposes that advance its growth strategy and to pay the cost of the capped call transactions described below. Luminar also intends to use a portion of the net proceeds to repurchase shares of its Class A common stock in an amount not to exceed the greater of $250 million and 50% of the aggregate principal amount of the notes being offered, including from certain purchasers of notes in privately negotiated transactions through one of the initial purchasers or its affiliate as Luminar’s agent, concurrently with or following the offering as well as through a variety of methods, which could include open market purchases, accelerated share repurchase transactions, 10b5-1 plans, other transactions that may be structured through investment banking institutions or a combination thereof. Luminar expects the purchase price per share of the Class A common stock repurchased from certain purchasers of notes in privately negotiated transactions to equal the closing price per share of Luminar’s Class A common stock on the date of pricing of the offering. These activities and Luminar’s repurchases of shares of its Class A common stock may cause an increase or avoid a decrease in the market price of its Class A common stock or the notes, and, to the extent the activity occurs during any observation period related to a conversion of notes, it could affect the amount and value of the consideration that noteholders will receive upon conversion of the notes. Any such share repurchases may increase, or prevent a decrease in, the market price of Luminar’s Class A common stock.

The notes will be senior unsecured obligations of Luminar and will accrue interest payable semi-annually in arrears. The notes will be convertible under certain circumstances into cash, shares of Luminar’s Class A common stock or a combination thereof, at Luminar’s election. The notes will mature on December 15, 2026, unless earlier converted, redeemed or repurchased. The interest rate, initial conversion rate and other terms of the notes are to be determined upon pricing of the offering.

In connection with the pricing of the notes, Luminar intends to enter into privately negotiated capped call transactions with one or more of the initial purchasers of the notes and/or their respective affiliates and/or other financial institutions (the “option counterparties”). The capped call transactions are expected generally to reduce the potential dilution to Luminar’s Class A common stock upon conversion of the notes and/or offset any cash payments Luminar is required to make in excess of the principal amount of converted notes, as the case may be, with such reduction and/or offset subject to a cap, which is subject to certain adjustments under the terms of the capped call transactions. If the initial purchasers of the notes exercise their option to purchase additional notes, Luminar expects to enter into additional capped call transactions with the option counterparties.

Luminar has been advised that, in connection with establishing their initial hedges of the capped call transactions, the option counterparties and/or their respective affiliates expect to enter into various derivative transactions with respect to Luminar’s Class A common stock and/or purchase shares of Luminar’s Class A common stock concurrently with or shortly after the pricing of the notes. This activity could increase (or reduce the size of any decrease in) the market price of Luminar’s Class A common stock or the notes at that time.

In addition, the option counterparties and/or their respective affiliates may modify their hedge positions by entering into or unwinding various derivatives with respect to Luminar’s Class A common stock and/or purchasing or selling Luminar’s Class A common stock or other securities of Luminar in secondary market transactions following the pricing of the notes and from time to time prior to the maturity of the notes (and are likely to do so following any conversion of the notes, any repurchase of the notes by Luminar on any fundamental change repurchase date, any redemption date or any other date on which the notes are retired by Luminar). This activity could also cause a decrease or avoid an increase in the market price of Luminar’s Class A common stock or the notes, which could affect the ability of noteholders to convert the notes and, to the extent the activity occurs following conversion or during any observation period related to a conversion of notes, it could affect the amount and value of the consideration that noteholders will receive upon conversion of such notes.

The notes will be offered only to persons reasonably believed to be qualified institutional buyers pursuant to Rule 144A under the Securities Act. Neither the notes, nor any shares of Luminar’s Class A common stock issuable upon conversion of the notes, have been registered under the Securities Act or the securities laws of any other jurisdiction, and unless so registered, may not be offered or sold in the United States absent registration or an applicable exemption from, or in a transaction not subject to, the registration requirements of the Securities Act and other applicable securities laws.

Neither this Current Report nor this announcement constitutes (x) an offer to sell, or the solicitation of an offer to buy, any of these securities or (y) an offer, solicitation or sale in any jurisdiction in which such offer, solicitation or sale is unlawful.
