Item 2.05 Costs Associated with Exit or Disposal Activities.
As part of its previously announced efforts to
review strategic alternatives to maximize shareholder value, on April 28, 2026, Passage Bio, Inc. (the “Company”)
announced a restructuring of its workforce (the “Restructuring Plan”) to decrease its operating expenses by
reducing the workforce by approximately 75%.
The implementation of the Restructuring Plan should
be substantially complete in the second and third quarters of 2026. Impacted employees are eligible to receive severance benefits. These
severance benefits are contingent upon an impacted employee’s execution (and non-revocation) of a severance agreement, which includes
a general release of claims against the Company.
The Company expects that the aggregate severance
and exit costs for the Restructuring Plan will be approximately $3.3 million, which will be recorded primarily in the second quarter of
2026. The cost that the Company expects to incur in connection with the Restructuring Plan is subject to a number of assumptions, and
actual results may differ materially. The Company may also incur additional costs not currently contemplated due to events that may occur
as a result of, or that are associated with, the Restructuring Plan as well as the Company’s review of strategic alternatives.
Forward-Looking Statements
This current report contains “forward-looking
statements” within the meaning of, and made pursuant to the safe harbor provisions of, the Private Securities Litigation Reform
Act of 1995, including, but not limited to: statements related to the expected costs associated with termination benefits and the
financial impact of the restructuring and the reduction in workforce, our evaluation of strategic alternatives, and the entry into or
completion of any strategic alternative transaction,. These forward-looking statements may be accompanied by such words as “aim,”
“anticipate,” “believe,” “continue,” “could,” “should,” “target,”
“estimate,” “expect,” “forecast,” “goal,” “intend,” “may,” “might,”
“plan,” “potential,” “possible,” “will,” “would,” and other words and terms
of similar meaning. These statements involve risks and uncertainties that could cause actual results to differ materially from those reflected
in such statements, including: uncertainties inherent in strategic review processes, such as the risk that no suitable strategic alternative
will be identified or consummated; and the other risks and uncertainties that are described in the Risk Factors section in documents the
company files from time to time with the Securities and Exchange Commission (SEC), and other reports as filed with the SEC. Passage Bio
undertakes no obligation to publicly update any forward-looking statement, whether written or oral, that may be made from time to time,
whether as a result of new information, future developments or otherwise.
SIGNATURE
Pursuant to the requirements of the Securities Exchange Act of 1934,
