SPECIAL NOTE REGARDING FORWARD-LOOKING STATEMENTS

This Quarterly Report on Form 10-Q contains forward-looking statements that involve risks, uncertainties, and other factors that may cause actual results, levels of activity, performance, or achievements to be materially different from the information expressed or implied by these forward-looking statements. All statements, other than statements of historical facts, contained in this Quarterly Report on Form 10-Q, including statements regarding our strategy, future operations, future financial position, future revenue, projected costs, prospects, plans and objectives of management and expected market growth are forward-looking statements. The words “may,” “can,” “anticipate,” “assume,” “should,” “indicate,” “would,” “believe,” “contemplate,” “expect,” “seek,” “estimate,” “continue,” “plan,” “point to,” “project,” “predict,” “could,” “intend,” “target,” “potential” and other similar words and expressions of the future are intended to identify forward-looking statements, although not all forward-looking statements contain these identifying words.

These forward-looking statements include, among other things, statements about:

•

our financial performance;

•

our ability to fund our planned operations for the next twelve months and our ability to continue as a going concern;

•

our expectations related to the use of our cash;

•

changes in our capital resource requirements;

•

our ability to obtain, maintain and protect our intellectual property rights, in particular those related to our product candidates;

•

our ability to realize the anticipated benefits of the merger (the "Kineta Merger") with Kineta Inc. ("Kineta");

•

the effects of the Kineta Merger on our business relationships, operating results and business generally;

•

expectations regarding the strategies, prospects, plans, expectations and objectives of our management for future operations of our company following the closing of the Kineta Merger;

•

unexpected costs, charges or expenses resulting from the Kineta Merger;

•

the cost, timing, scope and results of our clinical studies;

•

our ability to retain the continued service of our key professionals and to identify, hire and retain additional qualified professionals;

•

existing regulations and regulatory developments in the United States and other jurisdictions;

•

the impact of government laws, general economic and market conditions, inflation and imposition of new or revised global tariffs;

•

developments relating to our competitors and our industry;

•

the regulatory approval processes of the U.S. Food and Drug Administration and other comparable foreign regulatory authorities are lengthy, time-consuming and inherently unpredictable. If we are not able to obtain, or if there are delays in obtaining, required regulatory approvals for our product candidates, we will not be able to commercialize, or will be delayed in commercializing, such product candidates, and our ability to generate revenue will be materially impaired;

•

the therapeutic potential of IFx-2.0, IFx-3.0, TBS-2025, and future product candidates; and

•

other risks and uncertainties, including those listed under “Risk Factors” in our Annual Report on Form 10-K for the year ended December 31, 2024 (the “2024 Annual Report”).

We may not actually achieve the plans, intentions or expectations disclosed in our forward-looking statements, and you should not place undue reliance on our forward-looking statements. Actual results or events could differ materially from the plans, intentions and

ii expectations disclosed in the forward-looking statements we make. We have included important factors in the cautionary statements included in this Quarterly Report on Form 10-Q and our 2024 Annual Report filed with the Securities and Exchange Commission (“SEC“), or the SEC, on March 31, 2025, particularly in the “Risk Factors” section, that could cause actual results or events to differ materially from the forward-looking statements that we make. Our forward-looking statements do not reflect the potential impact of any future acquisitions, mergers, dispositions, collaborations, joint ventures or investments that we may make or into which we may enter.

You should read this Quarterly Report on Form 10-Q and the documents that we reference herein and have filed or incorporated by reference as exhibits hereto completely and with the understanding that our actual future results may be materially different from what we expect. We do not assume any obligation to update any forward-looking statements, whether as a result of new information, future events or otherwise, except as required by law.
