Item 2.05 Costs Associated with Exit or Disposal Activities.

On April 28, 2026, the Vertex, Inc. (the “Company”)

announced its Board of Directors (the “Board”) approved a global Value Creation Plan (the “Plan”) intended to

become a more AI-enabled company, focus investments on key growth opportunities and drive operational efficiency to better align the Company’s

workforce and resources with its long-term strategic priorities. The Plan includes a reduction in force of approximately 170 employees,

representing approximately 9% of the Company’s global workforce as of April 27, 2026.

In connection with the Plan, the Company estimates

that it will incur aggregate pre-tax charges of approximately $6 million to $8 million, consisting primarily of cash expenditures related

to employee severance, notice pay, statutory termination indemnities, and other employee separation benefits.

The Company expects to recognize the majority

of these charges in the first quarter of fiscal year 2026, with the remainder recognized in subsequent quarters as the Plan is implemented.

The estimates of the charges and cash expenditures

that the Company expects to incur in connection with the Plan, and the timing thereof, are subject to a number of assumptions, and actual

amounts may differ materially from these estimates. The Company may also incur additional charges or cash expenditures not currently contemplated

due to events that may occur as a result of, or in connection with, the implementation of the Plan, including local law requirements in

the jurisdictions in which the Company operates.

Cautionary Statement Regarding Forward-Looking Statements.

This Current Report on Form 8-K contains forward-looking

statements within the meaning of the Private Securities Litigation Reform Act of 1995, including, but not limited to, statements regarding

the Plan, the expected charges and cash expenditures associated with the Plan, the expected timing and completion of the Plan, the expected

workforce impact, and the anticipated benefits and cost savings from the Plan. These forward-looking statements are based on the Company’s

current expectations and assumptions and are subject to a number of risks, uncertainties, and other factors that could cause actual results

to differ materially from those anticipated, including, without limitation, the Company’s ability to implement the Plan in the manner

and on the timeline currently contemplated; the actual amount of charges and cash expenditures incurred in connection with the Plan; local

law requirements and consultation processes in the jurisdictions in which the Company operates; the impact of the Plan on the Company’s

employees, customers, suppliers, and operations; and the other risks and uncertainties described in the Company’s most recent Annual

Report on Form 10-K and subsequent reports filed with the U.S. Securities and Exchange Commission. The Company undertakes no obligation

to update any forward-looking statement, whether as a result of new information, future events, or otherwise, except as required by law.

SIGNATURE

Pursuant to the requirements of the Securities

Exchange Act of 1934, the registrant has duly caused this report to be signed on its behalf by the undersigned hereunto duly authorized.
