~~Item~~INTRODUCTORY ~~7.01.~~NOTE ~~Regulation FD Disclosure.~~

OnAs ~~December~~previously reported in the Current Report on Form 8-K filed with the U.S. Securities and Exchange Commission (the “SEC”) on November 1221, 2022, by Imago BioSciences, Inc., a Delaware corporation (“Imago”), ~~announced~~Imago ~~the~~entered ~~presentation~~into ofan ~~positive~~Agreement ~~data~~and ~~from~~Plan ~~ongoing Phase 2 study~~ of ~~Bomedemstat~~Merger in(the ~~Essential~~“Merger ~~Thrombocythemia (ET~~Agreement”), ~~and~~dated ~~in advanced myelofibrosis (MF)~~November 19, ~~respectively~~2022, atwith ~~the~~Merck ~~64th~~Sharp & ~~American~~Dohme ~~Society~~LLC, ofa ~~Hematology~~New ~~Annual~~Jersey ~~Meeting~~limited ~~and~~liability ~~Exposition~~company (~~ASH~~“Merck”)., ~~Copies~~and ofM-Inspire ~~the~~Merger ~~press~~Sub, ~~releases~~Inc., ~~Imago~~a ~~issued~~Delaware ~~announcing~~corporation ~~the~~and ~~positive~~a ~~data~~wholly ~~are~~owned ~~furnished~~subsidiary ~~herewith~~of asMerck ~~Exhibit~~(“Merger 99Sub”).1 ~~and~~All ~~Exhibit~~capitalized ~~99.2,~~terms ~~respectively,~~used herein and ~~are~~not ~~incorporated~~otherwise bydefined ~~reference~~have ~~into~~the ~~this~~meanings ~~Item~~given 7to such terms in the Merger Agreement.~~01.~~

~~The~~Pursuant ~~information~~to inthe ~~Item~~Merger ~~7.01~~Agreement, ~~including~~upon ~~Exhibit~~the ~~99.1~~terms and ~~Exhibit~~subject ~~99.2,~~to isthe ~~being~~conditions ~~furnished~~thereof, ~~and~~Merger ~~shall~~Sub ~~not~~commenced bea ~~deemed~~tender tooffer be(the “~~filed~~Offer”) ~~for~~on ~~purposes~~December 12, of2022 ~~Section 18~~to acquire all of the ~~Securities~~outstanding ~~Exchange~~shares ~~Act~~ of ~~1934,~~Imago’s ascommon ~~amended~~stock (the “~~Exchange Act~~Shares”), orfor ~~otherwise~~a ~~subject~~purchase toprice ~~the liabilities~~ of ~~that~~$36.00 ~~Section~~per ~~and~~Share, ~~shall not be deemed incorporated by reference into any registration statement or other document filed pursuant~~ to the ~~Securities~~seller ~~Act~~in ~~of 1933~~cash, aswithout ~~amended,~~interest orand ~~the~~subject ~~Exchange~~to ~~Act,~~any ~~except~~required astax ~~shall~~withholding be(the ~~expressly~~“Offer ~~set forth by specific reference in such filing~~Price”).

The Offer and related withdrawal rights expired as scheduled at one minute after 11:59 p.m., Eastern time, on January 10, 2023, and the Offer was not extended. American Stock Transfer & Trust Company, LLC, in its capacity as the depositary for the Offer, has advised that, as of the expiration of the Offer, 31,307,028 Shares were validly tendered and not validly withdrawn pursuant to the Offer, representing approximately 89.2% of all Shares then issued and outstanding as of the expiration of the Offer. The number of Shares tendered satisfied the Minimum Condition. As the Minimum Condition and each of the other conditions of the Offer have been satisfied, Merger Sub has accepted for payment all Shares that were validly tendered and not validly withdrawn pursuant to the Offer.

Following consummation of the Offer, the remaining conditions to the merger of Merger Sub with and into Imago (the “Merger”) set forth in the Merger Agreement were satisfied, and on January 11, 2023, Merck completed its acquisition of Imago by consummating the Merger without a meeting of stockholders of Imago in accordance with Section 251(h) of the General Corporation Law of the State of Delaware, with Imago continuing as the surviving corporation (the “Surviving Corporation”). At the effective time of the Merger (the “Effective Time”), Shares not purchased pursuant to the Offer (other than certain excluded Shares as described in the Merger Agreement) were converted into the right to receive the Offer Price in cash, without interest and subject to any required tax withholding (the “Merger Consideration”). As a result of the Merger, Imago became a wholly owned subsidiary of Merck.

Pursuant to the Merger Agreement, at the Effective Time, each Imago stock option (each, a “Company Stock Option”) to purchase Shares under any Imago stock plan, whether vested or unvested, that was outstanding immediately prior to the Effective Time was converted by virtue of the Merger into the right to receive a payment in cash (without interest and subject to deduction for any required tax withholding) equal to the product of (i) the excess of the Merger Consideration over the exercise price per Share under such Company Stock Option and (ii) the number of Shares subject to such Company Stock Option; provided, that if the exercise price per Share is equal to or greater than the Merger Consideration, such Company Stock Option shall be automatically cancelled without any cash payment being made in respect thereof and shall have no further force or effect.

The foregoing description of the Merger Agreement is not complete and is qualified in its entirety by reference to the Merger Agreement, a copy of which is filed as Exhibit 2.1 to Imago’s Current Report on Form 8-K, filed with the SEC on November 21, 2022, and is incorporated herein by reference.

Item 2.01.

Completion of Acquisition or Disposition of Assets.

The disclosures under the Introductory Note and Item 3.01 are incorporated herein by reference.

Item 3.01.

Notice of Delisting or Failure to Satisfy a Continued Listing Rule or Standard; Transfer of Listing.

The disclosures under the Introductory Note are incorporated herein by reference.

On January 11, 2023, Imago (i) notified the Nasdaq Stock Market LLC (“Nasdaq”) of the consummation of the Merger and (ii) requested that Nasdaq (A) suspend trading of the Shares effective before the opening of trading on January 11, 2023 and (B) file with the SEC a Form 25 Notification of Removal from Listing and/or Registration to

delist and deregister the Shares under Section 12(b) of the Securities Exchange Act of 1934, as amended (the “Exchange Act”). As a result, the Shares will no longer be listed on Nasdaq. Upon effectiveness of such Form 25, Imago intends to file with the SEC a certification on Form 15 under the Exchange Act, requesting the termination of registration of the Shares under Section 12(g) of the Exchange Act and the suspension of Imago’s reporting obligations under Sections 13 and 15(d) of the Exchange Act.

As a result of the consummation of the Offer and the Merger, there was a change in control of Imago, and Merck, as the direct parent of Merger Sub, acquired control of Imago.

Reinhoff, Jr., M.D. and Laurie Keating J.D. each ceased to be directors of Imago and members of any committee of Imago’s board of directors.
