Footnote F1

On April 30, 2026, the underwriters of the initial public offering ("IPO") of HMH Holding Inc. (the "Issuer") partially exercised their option to purchase (the "Over Allotment") additional shares of the Issuer's Class A Common Stock, par value $0.01 per share (the "Class A Common Stock"). In connection with the Over Allotment, the underwriters will purchase 685,844 shares of Class A Common Stock, and the transaction is anticipated to close on May 5, 2026. The Issuer will contribute the net proceeds from the Over Allotment, which will amount to $12,893,867.20, to HMH Holding B.V. ("HMH B.V."), and HMH B.V. will use such net proceeds to purchase in equal proportion from Baker Hughes (as defined below) and another stockholder of HMH B.V., respectively, an aggregate number of shares of Class B common stock of the Issuer (the "Issuer Class B Shares"),

Footnote F2

(Continued from footnote 1) non-voting Class A ordinary shares in HMH B.V. (the "B.V. Non-Voting Class A Shares") and non-voting Class B shares in HMH B.V. (the "B.V. Non-Voting Class B Shares"), respectively, equal to the number of shares of Class A Common Stock to be purchased by the underwriters pursuant to the Over Allotment. With regards to Baker Hughes, HMH B.V. will purchase the following securities for a purchase price of $6,446,933.60 to be paid to Baker Hughes: (i) 342,922 Issuer Class B Shares, (ii) 342,922 B.V. Non-Voting Class A Shares in exchange for $2,773,200.59 and (iii) 342,922 B.V. Non-Voting Class B Shares in exchange for $3,673,733.01.

Footnote F3

In this filing, Baker Hughes Company and Baker Hughes Holdings LLC are collectively referred to as "Baker Hughes". Baker Hughes Company has an indirect pecuniary interest in the securities held by Baker Hughes Holdings LLC. Consequently, Baker Hughes Company may be deemed to share beneficial ownership in the securities held directly by Baker Hughes Holdings LLC. The board of directors and officers of Baker Hughes Company disclaim beneficial ownership with respect to such securities.

Footnote F4

Pursuant to the Exchange Agreement, dated as of April 2, 2026, by and among the Issuer, HMH B.V. and the other parties thereto, Baker Hughes has the right to exchange one Issuer Class B Share, one B.V. Non-Voting Class A Share and one B.V. Non-Voting Class B Share for cash or shares of the Class A Common Stock on a one-for-one basis, subject to customary conversion rate adjustments (e.g. for stock splits, stock dividends and reclassifications). These rights are exercisable at any time after the conclusion of the Issuer's IPO lock-up period (i.e., September 27, 2026, unless the IPO lock-up is earlier released or waived by the underwriters of the Issuer's IPO) and do not expire.

Footnote F5

Judson E. Bailey and M. Georgia Magno are directors of the Issuer and were nominated for such roles by Baker Hughes Holdings LLC. By virtue of their service on the Board of Directors of the Issuer, for purposes of Section 16, Baker Hughes Holdings LLC may be deemed to be a "director by deputization" of the Issuer.
