Please revise your disclosure in the response to this question and on page 4 of the proxy statement/prospectus to briefly explain why CAH determined that neither it nor any of its officers, directors, sponsor, or advisors was affiliated with LumiraDx and therefore why CAH did not obtain a fairness opinion, third-party valuation or take any additional measures, such as the formation of an independent committee of the board.

We note the "major assumptions" referred to in your headnotes to the projections are not presented with any specificity. As such, and for each scenario presented, please provide the material assumptions underlying the revenue, EBITDA, and free cash flow projections, including asset, revenue and earnings growth rates, projected market penetration rates, discount rates, etc. The level of detail provided must be sufficient enough for an investor to understand the reasonableness of the assumptions underlying the projections as well as the inherent limitations on the reliability of projections in order to make informed investment decisions. To the extent that these projections assume changes in your historical operating trends, please revise your disclosure to address why the projected changes in trends are appropriate and why the assumptions underlying these projected changes are reasonable. In addition, in light of your limited commercial experience with your Platform and your launch of tests, ensure you fully explain how you arrived at your revenue projections. If you assessed the probability of regulatory/technical success, ensure you provide such details. Comparable M&A Transaction Analysis, page 122 10.

As such, the fair value of LumiraDx shares transferred to CAH shareholders in excess of the net assets of CAH will be recorded in Selling, Marketing and Administrative expenses. We see such adjustment in Note 6. Adjustments to Unaudited Pro Forma Condensed Combined Statement of Operations for the Year Ended December 31, 2020. However, under the caption, Anticipated Accounting Treatment, on page 126 you disclose that any difference between the fair Ron Zwanziger LumiraDx Limited June 28, 2021 Page 4 value of LMDX common shares and the fair value of CAH's identifiable net assets will be recorded as additional paid-in capital, in accordance with IFRS 2.

We note the revision made to pro forma adjustment 5(f) in response to comment 18 includes a reference to a 2.625766662:1 Subdivision. However, we note elsewhere in your filing that the February 1, 2021 Subdivision was 220:1 and that the 2.625766662 is the LMDX Conversion Factor. Please clarify and expand your disclosure to quantify the historical LMDX ordinary and common shares outstanding as of December 31, 2020, the additional shares issued as a result of the Subdivision and/or Conversion Factor and the number of shares shares issued upon the conversion of the outstanding series A and B preferred shares to arrive at the pro forma shares of LMDX ordinary and common shares.
