(the “Closing Date”), 908 Devices Inc. (the “Company”) completed its acquisition of NIRLAB SA, a corporation organized
under the laws of Switzerland (“NIRLAB”), and its wholly owned subsidiary, NIRLAB Forensics Sàrl, a limited liability
company organized under the laws of Switzerland (the “Subsidiary” and, together with NIRLAB, the “NIRLAB Group”),
pursuant to a Share Purchase Agreement (the “Purchase Agreement”) with Florentin Coppey, Pierre Esseiva, Matteo Delbrück,
Parkview Invest AG and Matthieu Girod (each a “Seller” and collectively, the “Sellers”) and NIRLAB. The NIRLAB
Group develops near-infrared (NIR) spectroscopy solutions for instant material identification. Under the Purchase Agreement, the Sellers
sold all 1,094,282 outstanding registered shares of NIRLAB (the "NIRLAB Shares"), constituting the entire issued share
capital of NIRLAB, to the Company. The board of directors of the Company (i) determined
that the terms of the Purchase Agreement are fair to, advisable and in the best interests of the Company and its stockholders, and (ii) authorized
and approved the execution, delivery and performance of the Purchase Agreement and the consummation of transactions contemplated thereby. Pursuant to the Purchase
Agreement, the Sellers agreed to sell and transfer to the Company, on the Closing Date (as defined below), all of the issued and outstanding
NIRLAB Shares in exchange for a preliminary consideration (the “Preliminary Consideration”) payable by the Company on the
Closing Date with a headline price of $15,000,000 (the “Transaction”), comprised of (x) $13,000,000 in cash (the “Cash
Consideration”) and (y) 293,368 shares of common stock of the Company, par value $0.001 per share (each such share,
a “Company Share”) (the “Stock Consideration”). The Cash Consideration is subject to customary
adjustments. The Company withheld $1,300,000 of the Cash Consideration and 10% of the Stock Consideration (together, the “General
Holdback Amount”) to secure the Sellers’ post-closing obligations under the Purchase Agreement. Subject to any outstanding
claims, the General Holdback Amount shall be released to the Sellers twelve (12) months after the Closing Date. The number of Company Shares issuable as Stock
Consideration was determined based on the higher of (x) the thirty (30)-day volume-weighted average price of the Company Shares on
Nasdaq immediately preceding the Closing Date and (y) a contractual floor price of USD 5.88 per share. In addition to the Preliminary Consideration, the
Sellers may receive contingent earn-out consideration of up to $8,000,000 (the “Earn-Out Consideration”), payable solely in
Company Shares, based on the achievement of certain revenue-based milestones by December 31, 2027, as more fully described in the
Purchase Agreement. In connection with the Transaction, all 36,750
options to purchase NIRLAB Shares outstanding as of the Closing Date were cancelled pursuant to option cancellation agreements entered
into between NIRLAB and the applicable option holders (the “Option Cancellation Agreements”), in exchange for a combination
of cash and Company Shares, where applicable (the “Option Share Payment”). The Purchase Agreement and Option Cancellation
Agreements contain provisions pursuant to which each Seller or applicable option holder, respectively, agrees not to sell or transfer
any Company Shares received as a result of the Transaction for a 180-day lock-up period from the date of issuance of such Company Shares,
subject to customary exceptions. The Purchase Agreement contains customary representations
and warranties by the Sellers relating to, among other things, the NIRLAB Group and their business, and customary representations and
warranties by the Company. The Purchase Agreement also contains customary indemnification provisions, pursuant to which the Sellers have
agreed to indemnify the Company for, among other things, breaches of representations and warranties and covenants, subject to certain
limitations, including time limitations and liability caps. In addition, the Purchase Agreement contains non-compete and non-solicitation
covenants pursuant to which each Seller has agreed, for a period of three (3) years following the Closing Date, not to compete with
the business of the NIRLAB Group or solicit employees, customers or suppliers of the NIRLAB Group, subject to certain exceptions. - 2 - The foregoing description
