Statement on Schedule 13D
This Amendment No. 1
(“Amendment No. 1”) amends and restates the Statement on Schedule 13D that was originally filed on October 2, 2018
(the “Original Schedule 13D”). This Amendment No. 1 relates to the beneficial ownership of Common Stock, $0.0001 par
value per share (“Common Stock”) of Y-mAbs Therapeutics, Inc., a Delaware corporation (“Issuer”) and is being
filed to reflect the acquisition of Common Stock by Sofinnova Venture Partners X, L.P., a Delaware limited partnership (“SVP X”),
Sofinnova Management X, L.L.C., a Delaware limited liability company (“SM X”), Dr. James I. Healy (“Healy”),
and Dr. Maha Katabi (“Katabi” and collectively with SVP X, SM X, and Healy, the “Reporting Persons”). This
Amendment No. 1 is being filed to update the aggregate percentage of the class of securities of the Issuer owned by the Reporting
Persons due to dilution caused by the Issuer’s additional sales of Common Stock from time to time since the date of the filing of
the Original Schedule 13D. The Issuer reported outstanding Common Stock in the Issuer’s Form 10-Q (File No. 001- 38650)
filed on November 4, 2021 causing a decrease in aggregate percentage ownership by the Reporting Persons of one percent (1%) or more

On April 24, 2018, Healy was granted a non-employee
stock option by the Issuer to purchase 32,000 shares of Common Stock at an exercise price of $11.16 per share. 1/36th of the shares of
the option vest in equal monthly installments starting April 24, 2018 until such time as the option is 100% vested, subject to Healy
continuing to be a service provider to the Issuer on each vesting date. Such option will expire on April 24, 2028.
In connection with the closing of the Issuer’s
initial public offering of Common Stock (the “Offering”), SVP X purchased 500,000 shares of Common Stock at $16.00 per share,
or $8,000,000 in the aggregate. Such purchase occurred pursuant to and on the terms set forth in the Issuer’s Prospectus filed pursuant
to Rule 424(b)(4) on September 24, 2018 with the Securities and Exchange Commission (the “Prospectus”).
On June 12, 2019, Healy was granted a non-employee
stock option by the Issuer to purchase 16,000 shares of Common Stock at an exercise price of $21.45 per share. The stock option vests
in equal monthly installments during the first year following the date of grant, subject to Healy’s continued service on the board
of directors of the Issuer, and is exercisable immediately upon vesting. Such option will expire on June 12, 2029.
In connection with the closing of a secondary
offering of Common Stock by the Issuer, on October 30, 2019, SVP X purchased 90,000 shares of Common Stock from the Issuer at a purchase
price of $28.00 per share, or $2,520,000 in the aggregate.
On January 15, 2020, Healy exercised stock
options for 25,778 shares of Common Stock.
On June 23, 2020, Healy was granted a non-employee
stock option by the Issuer to purchase 16,000 shares of Common Stock at an exercise price of $48.67 per share. The stock option vests
in equal monthly installments during the first year following the date of grant, subject to Healy’s continued service on the board
of directors of the Issuer, and is exercisable immediately upon vesting. Such option will expire on June 23, 2030.
On June 10, 2021, Healy was granted a non-employee
stock option by the Issuer to purchase 16,000 shares of Common Stock at an exercise price of $37.53 per share. The stock option vests
in equal monthly installments during the first year following the date of grant, subject to Healy’s continued service on the board
of directors of the Issuer, and is exercisable immediately upon vesting. Such option will expire on June 10, 2031.
Unless noted above, the source of the funds for
all purchases and acquisitions by the Reporting Persons was from working capital. Certain purchases by SVP X were made using its working
capital funded partially through a line of credit with Silicon Valley Bank in the normal course of business and then paid down from the
proceeds from investor capital calls.
Unless noted above, no part of the purchase price
was borrowed by any Reporting Person for the purpose of acquiring any securities discussed in this Item 3.
|
ITEM 4.
|
PURPOSE OF TRANSACTION.
|
The
Reporting Persons hold their securities of the Issuer for investment purposes. Depending on the factors discussed herein, the Reporting
Persons may, from time to time, acquire additional Common Stock and/or retain and/or sell all or a portion of the Common Stock held by
the Reporting Persons in the open market or in privately negotiated transactions, block sales or otherwise or pursuant to ordinary stock
exchange transactions effected through one or more broker-dealers whether individually or utilizing specific pricing or other instructions
(including by means of Rule 10b5-1 programs), and/or may distribute the Common Stock held by the Reporting Persons to their respective
members or limited partners. Any actions the Reporting Persons might undertake will be dependent upon the Reporting Persons’ review
of numerous factors, including, among other things, the price levels of the Common Stock, general market and economic conditions, ongoing
evaluation of the Issuer’s business, financial condition, operations and prospects; the relative attractiveness of alternative business
and investment opportunities, and other future developments. Except as set forth above, the
