Questions and Answers About the Proposals
Q: What shall be the relative equity stakes of Summit Shareholders, YS
Biopharma shareholders
immediately after the consummation of the Busi, page 13

2.       We note your response to prior comment 2 and the changes made to your
tabular
         disclosure on pages 13 and 14. The sum of the share amounts and
ownership interests
         presented in these tables do not equal the total pro forma shares
outstanding, presumably
         due to double-counting within the (a) Sponsor, (b) Sponsor and certain
Summit directors
         as a group and (c) Sponsor and its affiliates' total potential
ownership interest line items.
         Please revise your tables so that they are mathematically accurate and
agree to the pro
         forma shares outstanding presented elsewhere in the document. In this
regard, consider
         presenting those line items that are not included in the total pro
forma shares outstanding
         below the tables for informational purposes.

3.       We note your response to prior comment 3, including your revised
footnote disclosure
         where you discuss the Concert Agreement and disclosure that "[t]he
Concert Agreement
         will continue after the Business Combination and shall remain
effective unless otherwise
         terminated by mutual consent of the Concert Parties." Given that Mr.
Yi Zhang is a party
         to the Concert Agreement, please update your potential controlled
company disclosure on
         page 49, risk factor disclosure on page 119 and your disclosure of YS
Group and YS
         Biopharma Relationships and Related Party Transactions on page 369 to
discuss the
         Concert Agreement.

4.       We note your response to prior comment 5, including your revised
disclosure on page 163
         where you discuss how negotiations evolved during the course of the
parties exchanging
         letters of intent and reissue in part. For example, you state that "on
June 17, June 22, and
         June 26, 2022, respectively, YS Biopharma and Summit exchanged several
revised
         versions of the Second Draft LOI." Please update your disclosure to
discuss each
         party's position on the material issues negotiated in the several
revised versions of the
         Second Draft LOI and how and why such issues evolved to the resulting
Near-Final LOI
         or otherwise advise.

5.       You disclose that the revenue projections prepared by ValueScope were
based on
         estimates of the YSJA rabies, PIKA rabies and PIKA recombinant
COVID-19 vaccines,

         taking into consideration the clinical status and expected regulatory
approval pathway and
         timeline for each applicable product. You also disclose that
ValueScope reviewed
         projections provided by YS BioPharma's management and adjusted and
postponed the
         potential launch dates for PIKA rabies and PIKA recombinant COVID-19
vaccines and
         adjusted the projected market share ramp up accordingly. Please revise
to provide more
         detail as to how these estimates impacted your revenue projections. In
this regard, disclose
         the assumptions with respect to the timing of regulatory approval and
potential launch
         dates and quantify the projected market share ramp up in each period.
Summary of Valuation Analysis and Opinion of Financial Advisor to the Summit
Board
Projected Information, page 174

6.       We note your disclosure of the financial projections used and
accompanying cautionary
         language. Specifically, on page 175, where you state that due to the
inherent uncertainties
         in financial projections, "shareholders are cautioned not to place
undue, if any, reliance on
         projections" and on page 176, where you state "[shareholders] ARE
CAUTIONED NOT
         TO RELY ON THE PROJECTIONS." While it may be appropriate to caution
investors
         not to place undue reliance upon prospective financial information, it
is not appropriate to
         tell readers to not rely upon them at all since they are included in
your registration
         statement. Please delete the words "if any" and revise your
disclosures accordingly. In
         addition, we note your disclosure on page 176 and 177 where you
disclose that there is no
         intention to update or revise the forecasts to reflect circumstances
existing after the date
         when made or to reflect the occurrence of future events in the event
that any or all the
         assumptions underlying the forecasts are shown to be in error. Given
the amount of time
         that appears to have passed since the Valuation Date, please tell us
whether or not the
         projections still materially reflect management's views on future
performance and whether
         you intend to revise the forecast to reflect the occurrence of future
events prior to the
         consummation of the Business Combination.

7.       We note your response to our prior comment 11 and reissue. Please
address the following
         in your response as it relates to the 10,000,000 Public Warrants
specifically:
             Explain your analysis of the Tender Offer Provision described in
Section 4.5 of the
             Warrant Agreement filed as an exhibit to Summit's Registration
Statement on Form
             S-1 in determining that liability classification was required. In
this regard, explain
             how you applied the guidance in ASC 815-40-55-2 through
815-40-55-6 when
             analyzing the Tender Offer Provision.
             Explain whether the consummation of the business combination, and
particularly the
             elimination of the dual class structure of your common shares,
impacts your analysis
             under the guidance referenced above.
8.       You disclose at F-15 that on October 12, 2022, Summit had drawn down
$700,000 under
         the Convertible Promissory Note that may be converted into warrants.
Please tell us how

      you considered its pro forma impact on the balance sheet, as well as the
need to disclose it
      as part of the equity instruments excluded from the pro forma share
balances in Note (4) at
      page 330.
General

9.    We note your new risk factor on page 130 where you disclose that the
Business
      Combination may be subject to review and approval by the Committee on
Foreign
      Investment in the United States (   CFIUS   ), including your disclosure
that certain
      transactions "may be subject to mandatory pre-closing CFIUS filing
requirements." Please
      update your risk factor to disclose whether or not the Business
Combination is subject to
      the mandatory pre-closing CFIUS filing requirements or otherwise advise.
10.   We note your response to prior comment 14 and reissue. While you have
removed your
      disclosure on pages 41 and 42 and "confirmed with Summit, YS Biopharma
and the
      Sponsor that such persons do not intend to pursue any such transactions,"
your risk factor
      disclosure at the bottom of page 127 still states, "Sponsor, Summit   s
directors, officers
      and their affiliates may elect to purchase shares or warrants from Summit
Public
      Shareholders, which may influence a vote on the Business Combination and
reduce
      Summit   s public    float."" Please provide your analysis on how such
purchases comply
      with Rule 14e-5 or otherwise advise.
       You may contact Li Xiao at 202-551-4391 or Angela Connell at
