Regulation FD Disclosure. |
As previously disclosed, on June 5, 2022, Yumanity Therapeutics, Inc., a Delaware corporation (“Yumanity”), entered into an Asset Purchase
Agreement (the “Asset Purchase Agreement”) with Janssen Pharmaceutica NV (“Janssen”). Concurrently with the execution of the Asset Purchase Agreement, on June 5, 2022, Yumanity entered into an Agreement and Plan of Merger
with Kineta, Inc., a Washington corporation (“Kineta”), and Yacht Merger Sub, Inc., a Washington corporation and wholly-owned subsidiary of Yumanity.
Kineta has updated its corporate presentation (the “Corporate Presentation”), which it intends to use at various meetings with investors, investment
banks and investment bank analysts. The Corporate Presentation is attached hereto as Exhibit 99.1.
The information in this Item 7.01, including Exhibit
99.1 attached hereto, is being furnished, shall not be deemed “filed” for any purpose, and shall not be deemed incorporated by reference in any filing under the Securities Act of 1933, as amended (the “Securities Act”) or the
Securities Exchange Act of 1934, as amended, except as expressly set forth by specific reference in such a filing.
Important Information and Where to
Find It
This communication may be deemed to be solicitation material with respect to the proposed transactions between Yumanity and Kineta and between
Yumanity and Janssen. In connection with the proposed transactions, on August 29, 2022, Yumanity filed with the U.S. Securities and Exchange Commission (the “SEC”) a registration statement on Form
S-4 (the “Initial Registration Statement”), as amended by Amendment No. 1 to the Initial Registration Statement filed with the SEC on October 3, 2022 and as amended by Amendment No. 2
to the Initial Registration Statement filed with the SEC on October 24, 2022 (together with the Initial Registration Statement, the “Registration Statement”), which contains a preliminary proxy statement and prospectus. The
Registration Statement has not yet become effective. Yumanity will mail the definitive proxy statement/prospectus to the Yumanity securityholders, and the securities may not be sold or exchanged until the Registration Statement becomes effective.
Investors and securityholders of Yumanity and Kineta are urged to read these materials when they become available because they will contain important information about Yumanity, Kineta and the proposed transactions. This communication is not a
substitute for the Registration Statement, definitive proxy statement/prospectus or any other documents that Yumanity may file with the SEC or send to securityholders in connection with the proposed transactions.
Investors and securityholders may obtain free copies of the documents filed with the SEC, once available, on Yumanity’s website at www.yumanity.com, on
the SEC’s website at www.sec.gov or by directing a request to Yumanity’s Investor Relations at (212) 213-0006 ext. 331.
This communication shall not constitute an offer to sell or the solicitation of an offer to sell or the solicitation of an offer to buy any securities, nor
shall there be any sale of securities in any jurisdiction in which such offer, solicitation or sale would be unlawful prior to registration or qualification under the securities laws of any such jurisdiction. No offering of securities shall be made
except by means of a prospectus meeting the requirements of Section 10 of the Securities Act.
Participants in the Solicitation
Each of Yumanity, Kineta and their respective directors and executive officers may be deemed to be participants in the solicitation of proxies from the
stockholders of Yumanity in connection with the proposed transactions. Information about the executive officers and directors of Yumanity is set forth in Yumanity’s Definitive Proxy Statement on Schedule 14A relating to the 2022 Annual Meeting
of Stockholders, filed with the SEC on April 25, 2022. Other information regarding the interests of such individuals, who may be deemed to be participants in the solicitation of proxies for the stockholders of Yumanity, is set forth in the
preliminary proxy statement/prospectus included in the Registration Statement and will be set forth in the definitive proxy statement/prospectus and any other relevant documents to be filed with the SEC. You may obtain free copies of these documents

“could,” “designed to,” “estimates,” “expects,” “forecasts,” “goal,” “intends,” “may,” “plans,” “possible,” “potential,” “seeks,”
“will,” and variations of these words and phrases or similar expressions that are intended to identify forward-looking statements. These forward-looking statements include, without limitation, statements regarding the proposed merger

fact. Actual results and the timing of events could differ materially from those anticipated in such forward-looking statements as a result of these risks and uncertainties, which include, without limitation: (i) the risk that the conditions to
the closing of the proposed transactions are not satisfied, including the failure to timely obtain stockholder approval for the transactions, if at all; (ii) uncertainties as to the timing of the consummation of the proposed transactions and
the ability of each of Yumanity, Kineta and Janssen to consummate the proposed merger or asset sale, as applicable; (iii) risks related to Yumanity’s ability to manage its operating expenses and its expenses associated with the proposed
transactions pending closing; (iv) risks related to the failure or delay in obtaining required approvals from any governmental or quasi-governmental entity necessary to consummate the proposed transactions; (v) the risk that as a result of

unexpected costs that may result therefrom; (xii) risks related to the failure to realize any value from product candidates and preclinical programs being developed and anticipated to be developed in light of inherent risks and difficulties
involved in successfully bringing product candidates to market; and (xiii) risks associated with the possible failure to realize certain anticipated benefits of the proposed transactions, including with respect to future financial and operating
results. Actual results and the timing of events could differ materially from those anticipated in such forward-looking statements as a result of these risks and uncertainties. These and other risks and uncertainties are more fully described in
periodic filings with the SEC, including the factors described in the section titled “Risk Factors” in Yumanity’s Quarterly Report on Form 10-Q for the quarter ended June 30, 2022 filed
