Stockholders' Equity |
Stockholders' Equity | Note 13. Stockholders’ Equity Authorized Stock The Company has 100,000,000 authorized shares of common stock with a par value of $0.001 per share, and 2,500,000 undesignated or “blank check” preferred stock, with a par value of $0.001, of which, 800,000 shares have been designated as Class A Convertible Preferred Stock, 585,000 shares have been designated as Class B Convertible Preferred Stock and 250,000 shares have been designated as 4.0% Series C Convertible Preferred Stock. Repurchase Program In March 2022, the Company’s Board of Directors authorized a repurchase program (the “Repurchase Program”) through December 31, 2025, authorizing the repurchase of common stock and/or convertible senior notes in the amount of up to $100.0 million from time to time, on the open market or otherwise, in such quantities, at such prices, and in such manner as determined by the Company’s management at its discretion. The size and timing of any repurchase will depend on a number of factors, including the market price of the Company’s common stock, general market and economic conditions, and applicable legal requirements. The Company purchased 1,604,994 shares of its common stock under the Repurchase Program during the year ended December 31, 2022, at an average price of $23.63 per share, for an aggregate purchase price of $37.9 million. These shares were returned to the status of authorized but unissued shares of common stock. All share repurchases were made using cash resources and are reported in the period based on the settlement date of the applicable repurchase. No shares were purchased during the three months ended March 31, 2023. November 2021 Registered Direct Placement and Stock Purchase Agreements Concurrent with the issuance of the 2026 Senior Notes in November 2021, the Company conducted a registered direct placement of 3,072,038 shares of its common stock at $81.10 per share (“Concurrent Placement”). The Company received net proceeds of approximately $248.9 million, net of offering expenses. The Company used the net proceeds from the Concurrent Placement, together with a portion of the net proceeds from the issuance of the 2026 Senior Notes, to repurchase approximately $100.7 million principal amount of the 2025 Senior Notes in separate, privately negotiated repurchase transactions with a limited number of holders of the 2025 Senior Notes, for a cash repurchase price of approximately $351.1 million. The remainder of the net proceeds of approximately $288.4 million, after deducting banker fees, will be used for general corporate purposes (See Note 9). January 2021 Public Offering On January 25, 2021, the Company completed an underwritten public offering of 4,356,059 shares of its common stock. The shares were issued and sold pursuant to an underwriting agreement dated January 20, 2021, by and among the Company, on the one hand, and Morgan Stanley & Co. LLC, Jefferies LLC, SVB Leerink LLC and UBS Securities LLC, as representatives of certain underwriters at a public offering price per share of $66.00, before deducting underwriting discounts and commissions. The shares include 568,181 shares issued and sold pursuant to the underwriters’ exercise in full of their option to purchase additional shares of common stock pursuant to the underwriting agreement. The Company received net proceeds of approximately $269.8 million from the offering after deducting underwriting discounts and commissions and offering expenses paid by the Company. Blackstone Private Placement In connection with the MVE Acquisition, on October 1, 2020 (the “Closing Date”), the Company completed a private placement with an investment vehicle of funds affiliated with The Blackstone Group Inc. (collectively, “Blackstone”), consisting of (i) 250,000 shares of a newly designated 4.0% Series C Convertible Preferred Stock, par value $0.001 per share (“Series C Preferred Stock”), at a price of $1,000 per share, for $250.0 million, and (ii) 675,536 shares of common stock of the Company, par value $0.001 per share, for $25.0 million, for an aggregate purchase price of $275.0 million. The Company paid Blackstone $1.0 million as reimbursement for transactional expenses incurred in connection with the private placement at the Closing Date. Also, the Company incurred direct and incremental expenses of approximately $8.6 million, including financial advisory fees, closing costs, legal expenses and other offering-related expenses. The Company allocated the net proceeds of $265.4 million on a relative fair value basis to the Series C Preferred Stock and the common stock, resulting in allocated proceeds of $28.2 million and $237.2 million, respectively. The Series C Preferred Stock ranks senior to the shares of the Company’s common stock, with respect to dividend rights and rights upon the voluntary or involuntary liquidation, dissolution, or winding up of the affairs of the Company (a “Liquidation”). The Series C Preferred Stock has the following rights, preferences and privileges: Dividend Rights. Holders of the Series C Preferred Stock (the “Holders”) are entitled to dividends at the rate of 4.0% per annum, paid-in-kind, accruing daily and paid quarterly in arrears when and if declared by the Board of Directors. The Holders are also entitled to participate in dividends declared or paid on the common stock on an as-converted basis. The Company and Holders do not have the option to pay dividends in kind, in cash, or in other form. Paid in-kind dividends for the three months ended March 31, 2023 and the year ended December 31, 2022 were $2.0 million and $8.0 million, respectively. Liquidation Preference. Upon a Liquidation, each share of Series C Preferred Stock is entitled to receive an amount per share equal to the greater of (i) $1,000 per share, plus all accrued and unpaid dividends and (ii) the amount that the Holders of the Series C Preferred Stock would have been entitled to receive at such time if the Series C Preferred Stock were converted into common stock (the “Liquidation Preference”). Conversion Features. The Series C Preferred Stock is convertible at the option of the Holders at any time into shares of common stock at a conversion price of $38.6152 per share and a conversion rate of 25.90 shares of common stock per share of Series C Preferred Stock. At the Closing Date, the maximum number of shares of Common Stock that could be required to be issued if converted was 6,474,135 shares. The conversion price is subject to certain customary adjustments in the event of certain adjustments to the Company’s common stock, including stock dividends, splits, combinations, tender offers, and exchange offers. After the second anniversary of the Closing Date, subject to certain conditions, the Company may at its option require conversion of all of the outstanding shares of the Series C Preferred Stock to common stock if, for at least 20 trading days during the 30 consecutive trading days immediately preceding the date the Company notifies the Holders of the election to convert, the closing price of the Common Stock is at least 150% of the conversion price. On the October 1, 2020 issuance date, the effective conversion price per share was less than the fair value of the underlying common stock and, as a result, the Company determined that there was a beneficial conversion feature on that date. Accordingly, the Company recognized the resulting beneficial conversion feature amount of $39.5 million as a deemed dividend, equal to the number of common shares into which the Series C Preferred Stock is convertible multiplied by the difference between the fair value of the common stock and the effective conversion price per share on that date. Because the Series C Preferred Stock does not have a stated conversion date and was immediately convertible at the issuance date, the dividend is reflected as a one-time, non-cash, deemed dividend to the Holders of the Series C Preferred Stock on the date of issuance. Additionally, the Company determined that the nature of the Series C Preferred Stock is more akin to an equity instrument and that the economic characteristics and risks of the embedded conversion options are clearly and closely related to the Series C Preferred Stock. As such, the conversion options were not required to be bifurcated from the host under ASC 815, Derivatives and Hedging. Since the paid-in-kind dividends are nondiscretionary, the Company measures the beneficial conversion feature of the paid-in-kind dividends on the issuance date of the preferred stock and records such amount when the paid-in-kind dividends are accrued. Accordingly, the associated paid-in-kind dividends for the year ended December 31, 2020 generated a beneficial conversion feature amount of $0.3 million. On February 5, 2021, the Company received a waiver and conversion notice from Blackstone Freeze Parent L.P. and Blackstone Tactical Opportunities Fund – FD L.P. and converted an aggregate of 50,000 shares of the Series C Preferred Stock (see “—Blackstone Conversion” below for additional information). Redemption Rights. The Company may redeem the Series C Preferred Stock for cash, as follows: (1)At any time beginning five years after the Closing Date (but prior to six years after the Closing Date), all of the Series C Preferred Stock at a price equal to 105% of the purchase price paid plus any accrued and unpaid dividends. (2)At any time beginning six years after the Closing Date, all of the Series C Preferred Stock at a price equal to 100% of the purchase price paid plus any accrued and unpaid dividends. Upon a “Fundamental Change” (involving a change of control or de-listing of the Company as further described in the Certificate of Designation), each Holder has the right to require the Company to redeem all or any part of the Holder’s Series C Preferred Stock for an amount equal to the Liquidation Preference plus any accrued and unpaid dividends. If the Company does not have sufficient funds legally available to pay the repurchase price, then the Company is required to (a) pay the maximum amount of the repurchase price that can be paid out of funds legally available for payment, and (b) purchase any shares of the Series C Preferred Stock not purchased because of the foregoing limitations at the repurchase price as soon as practicable after the Company is able to make such purchase out of assets legally available for the purchase of such shares. If the Company fails to pay the repurchase price in full when due, then the Company will pay dividends on such shares not repurchased at a rate of 5.5% per annum until such shares are repurchased, payable quarterly in arrears. The Company evaluated the Series C Preferred Stock for liability or equity classification under the applicable accounting guidance including ASC 480, Distinguishing Liabilities from Equity, and determined that equity treatment was appropriate because the Series C Preferred Stock did not meet the definition of the liability instruments defined thereunder for convertible instruments. Specifically, the convertible preferred shares are not mandatorily redeemable and do not embody an obligation to buy back the shares outside of the Company’s control in a manner that could require the transfer of assets. Additionally, the Company determined that the Series C Preferred Stock would be recorded as permanent equity given that they are not redeemable for cash or other assets (i) on a fixed or determinable date, (ii) at the option of the holder, or (iii) upon the occurrence of an event that is not solely within control of the Company. The Company also evaluated the embedded put and call options within the Series C Preferred Stock in accordance with the accounting guidance for derivatives to determine if bifurcation is required. The Company determined that the economic characteristics and risks of the embedded put and call options are not clearly and closely related to the Series C Preferred Stock. Therefore, the Company assessed the put and call options further and determined they did not meet the definition of a derivative under ASC 815. Under the same analysis, the Company determined that the economic characteristics and risks of the embedded participating dividend feature are considered clearly and closely related to the equity host. Accordingly, the participating dividend feature is not required to be bifurcated under ASC 815. Also, the Company determined that the value of the contingent dividend feature is minimal and insignificant relative to the other components of the Series C Preferred Stock due to the circumstances surrounding the scenarios under which the provision would be triggered. Voting Rights. Holders of the Series C Preferred Stock are generally entitled to vote with the holders of the shares of common stock on an as-converted basis, subject to certain Nasdaq voting limitations, if applicable. Also, the consent of the Holders of a majority of the outstanding shares of the Series C Preferred Stock is required with respect to (i) amendments to the Company’s organizational documents that have an adverse effect on the Holders of the Series C Preferred Stock, and (ii) issuances by the Company of securities that are senior to, or equal in priority with, the Series C Preferred Stock. Holders of the Series C Preferred Stock have the right to nominate for election one member to the board of directors of the Company for so long as they hold 66.67% of the Series C Preferred Stock issued to them at the Closing Date. Registration Rights. Holders of the Series C Preferred Stock have certain customary registration rights with respect to the Series C Preferred Stock and the shares of common stock into which they are converted, pursuant to the terms of a registration rights agreement. The Company is required to file within 90 days of the Closing Date, and use its commercially reasonable efforts to cause to go effective as promptly as practicable, a registration statement covering the sale or distribution of common stock issued or issuable upon conversion of the Series C Preferred Stock. In December 2020, the Company filed an automatic shelf registration statement to register the resale of the common stock issued or issuable upon conversion of the Series C Preferred Stock. Blackstone Conversion On February 5, 2021, the Company received a waiver and conversion notice from Blackstone Freeze Parent L.P. and Blackstone Tactical Opportunities Fund – FD L.P. to convert an aggregate of 50,000 shares of the Company’s Series C Preferred Stock. Pursuant to the terms of the waiver and conversion notice, the Company also agreed to waive its right under the certificate of designations of the Series C Preferred Stock to redeem up to 50,000 shares of the Series C Preferred Stock prior to the 180-day anniversary of October 1, 2020, the issue date of the Series C Preferred Stock. The forgoing conversion, effective as of February 5, 2021, resulted in the issuance of an aggregate of 1,312,860 shares of common stock and $1.8 million in expenses.
