Item 8.01 Other Events

Litigation Relating to the Merger



As previously disclosed, on July 7, 2022, Meridian Bioscience, Inc., a
corporation organized under the laws of Ohio ("Meridian"), on the one hand, and
SD Biosensor, Inc., a corporation with limited liability organized under the
laws of the Republic of Korea, Columbus Holding Company, a corporation organized
under the laws of Delaware ("Columbus Holding") and Madeira Acquisition Corp., a
corporation organized under the laws of Ohio and a direct wholly owned
subsidiary of Parent ("Merger Sub"), on the other hand, entered into an
Agreement and Plan of Merger (as it may be amended, supplemented or otherwise
modified from time to time, the "merger agreement"). Upon the terms and subject
to the conditions set forth in the merger agreement, Columbus Holding will
acquire Meridian through a merger of Merger Sub with and into Meridian, with
Meridian surviving as a wholly owned subsidiary of Columbus Holding (the
"Transaction").

On August 25, 2022, Meridian filed with the U.S. Securities and Exchange
Commission (the "SEC") a preliminary proxy statement on Schedule 14A relating to
the special meeting of Meridian shareholders to be held on October 10, 2022 (the
"Preliminary Proxy Statement") to, among other things, vote on a proposal to
adopt the merger agreement. Meridian subsequently, on September 8, 2022, filed a
definitive proxy statement (the "Definitive Proxy Statement," and collectively
with the Preliminary Proxy Statement, the "Proxy Statement").

As of September 30, 2022, five lawsuits have been filed in federal court
(collectively, the "Lawsuits"), against Meridian and the members of the Meridian
Board (collectively, the "Defendants"), each relating to the Transaction. The
Lawsuits are, in the order they were filed: Warren v. Meridian Bioscience, Inc.
et al, No. 1:22-cv-07727 (S.D.N.Y. Sept. 9, 2022); Stein v. Meridian Bioscience,
Inc. et al, 1:22-cv-07814 (S.D.N.Y. Sept. 13, 2022); Coffman v. Meridian
Bioscience, Inc. et al, 1:22-cv-07984 (S.D.N.Y. Sept. 19, 2022); Morgan v.
Meridian Bioscience, Inc. et al, 1:22-cv-08057 (S.D.N.Y. Sept. 21, 2022) and
Scott v. Meridian Bioscience, Inc. et al, 1:22-cv-08114 (S.D.N.Y. Sept. 22,
2022). Additionally, eight purported Meridian shareholders sent demand letters,
dated September 1, 2022, September 3, 2022, September 16, 2022, September 16,
2022, September 21, 2022, September 22, 2022, September 23, 2022 and
September 26, 2022, respectively (collectively, the "Demand Letters," and
together with the Lawsuits, the "Actions"), but none of these individuals have
yet filed suit.

The Actions generally allege that the Proxy Statement misrepresents and/or omits
certain purportedly material information and assert violations of Sections 14(a)
and 20(a) of the Securities Exchange Act of 1934, as amended, and the rules
promulgated thereunder. The alleged material misstatements and omissions relate
to, among other topics, the opinion of Rothschild & Co US Inc. ("Rothschild &
Co"), Meridian's financial advisor in connection with the Transaction; the
financial projections provided by Meridian management; and certain background
events that occurred in connection with entering into the Transaction.

Among other relief, the plaintiffs in the Actions seek injunctive relief,
including directing Meridian to disclose the allegedly omitted material
information, enjoining the Transaction unless and until Meridian discloses the
allegedly omitted material information, rescinding the Transaction in the event
the Transaction is consummated and awarding rescissory damages and an award of
attorneys' fees and expenses.

Meridian and the Meridian Board deny the allegations in the Actions and deny any
alleged violations of law or any legal or equitable duty. The Defendants believe
that the Actions are without merit, and that no further disclosure is required
under applicable law. Nonetheless, solely to avoid the costs, risks, and
uncertainties inherent in litigation and to avoid the risk of litigation
delaying or adversely affecting the Transaction, and without admitting any
liability or that the supplemental disclosures below are material or otherwise
required by law, Meridian and the Meridian Board are voluntarily making
supplemental disclosures (the "supplemental disclosures") related to the
Transaction, as set forth herein.

--------------------------------------------------------------------------------
The supplemental disclosures in this Current Report on Form 8-K supplement the
disclosures contained in the Definitive Proxy Statement and should be read in
conjunction with the disclosures contained in the Definitive Proxy Statement,
which in turn should be read in its entirety. To the extent that information in
this Current Report on Form 8-K differs from or conflicts with information
contained in the Definitive Proxy Statement, the information in this Current
Report on Form 8-K shall supersede or supplement the information in the
Definitive Proxy Statement. Nothing in this Current Report on Form 8-K shall be
deemed an admission of the legal necessity or materiality under applicable laws
of any of the supplemental disclosures set forth herein, taken individually or
in the aggregate. Page references in the below disclosure are to pages in the
Definitive Proxy Statement, and defined terms used but not defined herein have
the meanings ascribed to such terms in the Definitive Proxy Statement.

The supplemental disclosures do not modify the Merger Consideration (as defined
in the merger agreement) or the timing of the special meeting of Meridian
shareholders scheduled for October 10, 2022 at 10:00 a.m. Eastern Time, to be
held virtually via the Internet at www.virtualshareholdermeeting.com/VIVO2022SM.

The Meridian Board continues to unanimously recommend that Meridian shareholders
vote: (1) "FOR" the adoption of the merger agreement; (2) "FOR" the compensation
proposal; and (3) "FOR" the adjournment proposal.

Supplemental Disclosures



The disclosures under the subsection captioned "The Merger (Proposal
1)-Background of the Merger" are hereby amended and supplemented by adding the
text underlined below to the last paragraph on page 40 of the Definitive Proxy
Statement:

During the June 16, 2022 meeting of the special committee, Mr. Kenny also
updated the members of the special committee that "Party D," a global life
science investor, and its portfolio company, "Party E," had reached out to
Mr. Kenny and expressed interest in acquiring Meridian's life science business.
However, they did not indicate any interest in also acquiring Meridian's
diagnostics business and past informal discussions had indicated Party D and
Party E would not have any interest in acquiring Meridian as a whole. A
discussion ensued whether Party D and Party E should be added to the market
check process. The special committee discussed the value of Meridian as a whole
compared to the values of the life science and diagnostic business units if they
were to be sold separately, potential tax inefficiencies resulting from the
separate sale of one of Meridian's business units, and the fact that the
remaining company comprised of only one of the two business units would not be
large enough to be viable as a public company. Based on those considerations,
the special committee expressed the view that the sale of Meridian as a whole
would likely generate substantially more value for the Meridian shareholders
than separate business unit sales and determined not to include Party D and
Party E in the market check at that stage. The special committee determined to
nonetheless keep the communication with Party D and Party E open in the event
that they were to become open to an acquisition of the entire company.

The disclosures under the subsection captioned "The Merger (Proposal
1)-Background of the Merger" are hereby amended and supplemented by adding the
text underlined below to the first full paragraph on page 42 of the Definitive
Proxy Statement:

At the June 28, 2022 Meridian Board meeting, Representatives of Rothschild & Co
also reported to the Meridian Board that, by June 28, 2022, as part of the
market check previously authorized by the Meridian Board, Rothschild & Co (on
behalf of Meridian) had reached out to various potential counterparties that
might be interested in acquiring Meridian, including seven financial sponsors,
which, among others, included Party A, Party B and Party C that had also been
included in the 2021 market check, and six strategic operating companies, to
inquire whether they would have an interest in acquiring Meridian. Out of those
parties, six financial sponsors, including Party A, Party B and Party C, and one
strategic operating company, "Party F," a large U.S.-based public company active
in the same space as Meridian, executed confidentiality agreements with
Meridian, while one financial sponsor and five strategic operating companies
indicated for various reasons that they were not interested in an acquisition of
Meridian. Consistent with the confidentiality agreement that Meridian executed
with the buyer consortium on March 3, 2022, all of the confidentiality
agreements entered into with those potential counterparties included

--------------------------------------------------------------------------------
customary standstill provisions (surviving for a period of 12 to 24 months) that
would terminate if Meridian entered into (or Meridian publicly announced or the
Meridian Board approved) a definitive agreement providing for, among other
things, a merger following which Meridian shareholders would own less than 50%
of the voting securities of the surviving company. Accordingly, all of the
standstill provisions included in confidentiality agreements entered into by
Meridian prior to execution of the merger agreement are no longer in force or
effect. As part of the diligence that such potential counterparties performed,
Meridian provided to those parties who executed confidentiality agreements,
among other materials, a management presentation, certain financial information
and the Updated Meridian projections. Due, however, to competitive sensitivity
Meridian provided Party F with a summary of the Updated Meridian projections,
rather than a fully detailed set of projections. Rothschild & Co received verbal
feedback from Party C indicating that it would not be in a position to offer a
price that would be materially higher than the $26.00 proposed in September
2021. Except for Party C and Party F, all potential counterparties ultimately
indicated that they would not be interested in acquiring Meridian, with a
majority citing concerns regarding Meridian's near and medium-term financial
performance as the COVID-19 pandemic matures and COVID-19-related testing
continues to decline. Representatives of Rothschild & Co provided Party F with a
proposed draft of Meridian's confidentiality agreement (that had been provided
to other potential counterparties) on June 6, 2022. Rothschild & Co had not
received a response to the proposed draft confidentiality agreement from Party F
and so followed up with Party F on June 8, 2022, June 16, 2022 and June 20,
2022. Representatives of Rothschild & Co. received a proposed markup of the
confidentiality Agreement from Party F on June 21, 2022. Between June 21, 2022
and June 28, 2022, representatives of Jones Day negotiated the terms of the
confidentiality agreement with Party F, as Party F expressed significant
reluctance to agree to various provisions that had been accepted by all other
counterparties that had entered into confidentiality agreements with Meridian.
Party F additionally had requested additional diligence information that was
broad in scope and competitively sensitive and Meridian's management team
reported that additional time to negotiate the scope of, and respond to Party
F's request would be needed.

The disclosures under the subsection captioned "The Merger (Proposal
1)-Background of the Merger" are hereby amended and supplemented by adding the
text underlined below to the sixth paragraph on page 43 of the Definitive Proxy
Statement:

During the July 1, 2022, special committee meeting, the special committee and
representatives of Rothschild & Co also discussed the status of the process with
Party F. The special committee instructed the representatives of Rothschild & Co
to request a revised question list from Party F and offer a time for a meeting
during the week of July 4, 2022. The special committee concluded that it would
be preferrable to meet with Party F in advance of executing a definitive
agreement with the buyer consortium, if possible, but that transaction certainty
was also of paramount concern. Members of Meridian's management expressed
concerns about Party F's bona fide interest in acquiring the company based on
the scope of the diligence requests and the lengthy period of time (almost three
weeks) to enter into a confidentiality agreement with Meridian. On July 1, 2022,
in accordance with the special committee's instructions, representatives of
Rothschild & Co requested a revised question list from Party F and suggested a
meeting the following week with the Meridian management team. Representatives of
Party F did not respond to this request prior to the Meridian Board meeting on
July 6, 2022, at which the Meridian Board recommended that the Meridian
shareholders adopt the merger agreement.

The disclosures under the subsection captioned "The Merger (Proposal 1)-Opinion
of Meridian's Financial Advisor-Selected Public Company Analysis" are hereby
amended and supplemented by adding the text underlined below to the first
paragraph on page 53 of the Definitive Proxy Statement:

Based on the 2022E EV/Revenue and 2023E EV/Revenue multiples calculated above
and on Rothschild & Co's professional judgment, Rothschild & Co applied an
illustrative range of EV/ Revenue of 2.25x to 3.75x and 2.75x to 3.75x to the
estimated consolidated revenue of Meridian for its fiscal years 2022 and 2023,
respectively, each as provided in the Updated Meridian projections, to reach a
range of implied EVs for Meridian for fiscal years 2022 and 2023. Based on the
2022 estimated EV/EBITDA and 2023 estimated

--------------------------------------------------------------------------------
EV/EBITDA multiples calculated above and on Rothschild & Co's professional
judgment, Rothschild & Co applied an illustrative range of EV/EBITDA of 11.0x to
13.5x and 11.5x to 14.0x to the estimated EBITDA of Meridian for its fiscal
years 2022 and 2023, respectively, each as provided in the Updated Meridian
projections, to reach a range of implied EVs for Meridian for fiscal years 2022
and 2023. To calculate implied equity values, Rothschild & Co then subtracted
from such implied EVs the $32 million of Meridian's debt, government grants, and
other debt-like items, and added to such implied EVs the $85 million of
Meridian's consolidated cash and cash equivalents, each as of May 31, 2022 and
as provided and approved for Rothschild & Co's use by the management of
Meridian. Rothschild & Co then divided such implied equity values by the number
of fully diluted outstanding shares of Meridian common stock, as provided by the
management of Meridian and approved for Rothschild & Co's use, to reach the
following implied per share equity value reference ranges for Meridian, rounded
to the nearest $0.05, as compared to the merger consideration:

The disclosures under the subsection captioned "The Merger (Proposal 1)-Opinion

hereby amended and supplemented by adding the text underlined below to the first
paragraph on page 56 of the Definitive Proxy Statement:

Based on the EV/LTM Revenue multiple calculated for the selected transactions
and on Rothschild & Co's professional judgment, Rothschild & Co applied an
illustrative range of EV/LTM Revenue of 3.5x to 4.5x to the estimated LTM
Revenue of Meridian for the period ended September 30, 2022, as provided in the
Updated Meridian projections, to reach a range of implied EVs for Meridian.
Based on the EV/LTM EBITDA multiple calculated for the selected transactions and
on Rothschild & Co's professional judgment, Rothschild & Co applied an
illustrative range of EV/LTM EBITDA of 13.5x to 15.5x to the estimated LTM
EBITDA of Meridian for the period ended September 30, 2022, as provided in the
Updated Meridian projections, to reach a range of implied EVs for Meridian.
Based on the EV/NTM Revenue multiple calculated for the selected transactions
and on Rothschild & Co's professional judgment, Rothschild & Co applied an
illustrative range of EV/NTM Revenue of 3.5x to 4.5x to the estimated NTM
Revenue of Meridian for the period ended September 30, 2023, as provided in the
Updated Meridian projections, to reach a range of implied EVs for Meridian.
Based on the EV/NTM EBITDA multiple calculated for the selected transactions and
on Rothschild & Co's professional judgment, Rothschild & Co applied an
illustrative range of EV/NTM EBITDA of 12.0x to 14.5x to the estimated NTM
EBITDA of Meridian for the period ended September 30, 2023, as provided in the
Updated Meridian projections, to reach a range of implied EVs for Meridian. To
calculate implied equity values, Rothschild & Co then subtracted from such
implied EVs the $32 million of Meridian's debt, government grants, and other
debt-like items and added to such implied EVs, the $85 million of Meridian's
consolidated cash and cash equivalents, each as of May 31, 2022 and as provided
and approved for Rothschild & Co's use by the management of Meridian.
Rothschild & Co then divided such implied equity values by the number of fully

Proxy Statement:

Rothschild & Co performed a discounted cash flow analysis for Meridian in order
to derive an implied per share equity value reference range for the entire
company if it were to remain an independent public company, and then compared
this implied per share equity value reference range with the merger
consideration provided for in the merger agreement. In this analysis,
Rothschild & Co calculated a range of implied EVs for Meridian by adding (i) the
estimated unlevered, after-tax free cash flows that Meridian was forecasted to
generate from the four months ended September 30, 2022 through the end of fiscal
year 2027 based on the Updated Meridian projections provided by the management
of Meridian, discounted to present value, as of May 31, 2022, after the
application of a range of illustrative discount rates, which were based on the
estimated weighted average cost of capital, which Rothschild & Co refers to as
"WACC," for Meridian to (ii) the present value, as of May 31, 2022 of the
implied terminal value of Meridian, after the application of a range of
illustrative discount rates based on the estimated WACC for Meridian.
Rothschild & Co estimated the terminal value of Meridian by applying an
illustrative range of growth rates in perpetuity of 2.25% to 3.25%, which
Rothschild & Co selected using its experience and professional judgment and
taking into account the Updated Meridian projections and certain metrics for the
U.S. economy and financial markets generally, to the estimated unlevered
after-tax free cash flows included in the Updated Meridian projections for the
terminal period, which resulted in a range of estimated terminal values, after
the application of a range of illustrative discount rates, the midpoint of which
was $1.087 billion.

--------------------------------------------------------------------------------
Unlevered, after-tax free cash flows for the terminal period were calculated as
net operating profit after taxes, which we refer to as "NOPAT," after
application of the illustrative range of growth rates described above, plus
depreciation and amortization, less capital expenditures, less change in net
working capital. Rothschild & Co used the mid-year discounting convention and
applied a range of illustrative discount rates of 9.5% to 11.0%, based on an
estimated WACC of 10.25%., which Rothschild & Co calculated Meridian's WACC
using its professional judgment and experience and based on the traditional CAPM
(capital asset pricing model). CAPM requires certain Meridian-specific inputs
including target capital structure weightings, the cost of long term debt,
future applicable marginal cash tax rates, levered and unlevered betas as well
as certain financial metrics for the U.S. financial markets generally.

Rothschild & Co calculated a range of implied equity values for Meridian by
subtracting from the range of combined implied EVs the $32 million of Meridian's
debt and government grants as of May 31, 2022, and by adding to the range of
combined implied EVs the $85 million of Meridian's consolidated cash and cash
equivalents as of May 31, 2022, each as provided and approved for Rothschild &
Co's use by the management of Meridian. Rothschild & Co then divided the ranges
of implied equity values for Meridian by the number of fully diluted outstanding
shares of Meridian common stock, as provided by the management of Meridian and
approved for Rothschild & Co's use. These analyses indicated the following
implied per share equity value reference ranges for Meridian, rounded to the
nearest $0.05, as compared to the merger consideration:
