“Legal Proceedings Related to the Tender Offer.

On March 16, 17, 20 and 26, 2020, complaints were filed in federal courts by purported stockholders of Forty Seven regarding the Merger. The first complaint, filed on an individual basis by the plaintiff, is captioned Stephen Bushansky v. Forty Seven, Inc., et al., No. 3:20-cv-01853 (N.D. Cal. filed Mar. 16, 2020). The second complaint, filed as a putative class action, is captioned Joseph Post v. Forty Seven, Inc., et al., No. 1:20-cv-00377 (D. Del. filed Mar. 17, 2020). The third complaint, filed on an individual basis by the plaintiff, is captioned Jason Augustine v. Forty Seven, Inc., et al., No. 5:20-cv-01978 (N.D. Cal. filed Mar. 20, 2020). The fourth complaint, filed on an individual basis by the plaintiff, is captioned Glenn Parr v. Forty Seven, Inc., et al., No. 3:20-cv-02104 (N.D. Cal. filed Mar. 26, 2020). The fifth complaint, filed on an individual basis by the plaintiff, is captioned Cole Demyon v. Forty Seven, Inc., et al., No. 5:20-cv-02111 (N.D. Cal. filed Mar. 26, 2020) (collectively, the “Federal Complaints”). The Federal Complaints name as defendants Forty Seven and each member of the Forty Seven Board. The Post complaint additionally names as defendants Parent and Purchaser. The Federal Complaints allege violations of Section 14(e) of the Exchange Act against all defendants, and assert violations of Section 20(a) of the Exchange Act against the individual defendants. The Post complaint additionally alleges a violation of Section 14(d) of the Exchange Act against all defendants and a violation of Section 20(a) of the Exchange Act against Parent and Purchaser, and the Demyon complaint additionally alleges breach of the fiduciary duty of candor against the individual defendants. The plaintiffs contend that the Schedule 14D-9 omitted or misrepresented material information regarding the Merger. The Federal Complaints seek (i) injunctive relief preventing the consummation of the Transactions; (ii) rescissory damages or rescission in the event the Transactions are consummated; and (iii) an award of plaintiff’s expenses and attorneys’ fees. The Post and Parr complaints additionally seek dissemination of a recommendation statement that discloses certain information requested by that plaintiff, and the Augustine and Demyon complaints seek an accounting of purported damages. Parent and Purchaser believe the claims asserted in the Federal Complaints are without merit.

On March 20, 2020, a complaint was filed in state court by a purported stockholder of Forty Seven regarding the Merger. The complaint, filed as a putative class action, is captioned Darryl Hawkins v. Forty Seven, Inc., et al., case number pending (Cal. Super. Ct., San Mateo, filed Mar. 20, 2020). The Hawkins complaint names as defendants Forty Seven and certain members of the Forty Seven Board. The Hawkins complaint alleges breach of fiduciary duty claims against the individual defendants and an aiding and abetting breach of fiduciary duty claim against Forty Seven. The plaintiff contends that the Transactions are unfair and undervalue Forty Seven, and that the Schedule 14D-9 omitted or misrepresented material information regarding the Merger. The Hawkins complaint seeks (i) injunctive relief preventing the consummation of the Transactions; (ii) rescissory damages or rescission in

the event the Transactions are consummated; (iii) injunctive relief directing the individual defendants to commence a sale process; (iv) an accounting of purported damages; and (v) an award of plaintiff’s expenses and attorneys’ fees. Parent and Purchaser believe the claims asserted in the Hawkins complaint are without merit.

Additional lawsuits may be filed against Forty Seven, the Forty Seven Board, Parent and/or Purchaser in connection with the Transactions, the Schedule TO and the Schedule 14D-9.”

The information set forth in the Offer to Purchase under “The Tender Offer—Section 15—Certain Legal Matters; Regulatory Approvals” and Items 1 through 11 of the Schedule TO, to the extent such Items incorporate by reference the information contained in the Offer to Purchase, are hereby amended and supplemented by replacing the last paragraph of the subsection titled “Antitrust,” as such paragraph was added by Amendment No. 1 to the Offer to Purchaser filed with the SEC on March 12, 2020, with the following paragraph:

“On March 12, 2020, each of Parent and Forty Seven filed a Premerger Notification and Report Form with the FTC and the Antitrust Division in connection with the purchase of Shares in the Offer. The required waiting period under the HSR Act with respect to the Offer expired at 11:59 p.m., Eastern Time on March 27, 2020. Accordingly, the HSR Condition in Section 13—“Conditions of the Offer” has been satisfied.”
