pursuant to the safe harbor provisions of Section 27A of the Securities Act of 1993, as amended, and Section 21E of the Securities Exchange Act of 1934, as amended. Such statements are based upon current plans, estimates and expectations
of the management of Infinity and MEI that are subject to various risks and uncertainties that could cause actual results to differ materially from such statements. The inclusion of forward-looking statements should not be regarded as a
representation that such plans, estimates and expectations will be achieved. Words such as “anticipate,” “expect,” “project,” “intend,” “believe,” “may,” “will,” “should,” “plan,” “could,” “continue,” “target,” “contemplate,” “estimate,”
“forecast,” “guidance,” “predict,” “possible,” “potential,” “pursue,” “likely,” and words and terms of similar substance used in connection with any discussion of future plans, actions or events identify forward-looking statements. All
statements, other than historical facts, including statements regarding: the expected timing of the closing of the Merger; the ability of the parties to complete the Merger; the expected benefits of the Merger, including estimations of
anticipated cost savings and cash runway; the competitive ability and position of the combined company; the potential, safety, efficacy, and regulatory and clinical progress of the combined company’s
product candidates, including the anticipated timing for initiation of clinical trials and release of clinical trial data and the expectations surrounding potential regulatory submissions, approvals and timing thereof; the sufficiency of
the combined company’s cash, cash equivalents and short-term investments to fund operations; and any assumptions underlying any of the foregoing, are forward-looking statements. Actual results could differ materially from those contained
in any forward-looking statement as a result of various factors, including the risks and other factors discussed in Infinity’s and MEI’s filings with the SEC, including under the heading “Risk Factors” in the joint proxy
statement/prospectus included in the Registration Statement on Form S-4 filed by MEI with the Securities and Exchange Commission (“SEC”) (the “Registration Statement”), and in Infinity’s most recent Annual Report on Form 10-K, Quarterly
Reports on Form 10-Q and Current Reports on Form 8-K filed with the SEC. Neither Infinity nor MEI assumes any obligation to update any forward-looking statements or information, which speak as of their respective dates, to reflect events or
circumstances after the date of this communication, or to reflect the occurrence of unanticipated events, except as may be required under applicable securities laws.
