Item 2.05 Costs Associated with Exit or Disposal Activities.
On November 30, 2023, the Board of Directors of Yield10 Bioscience, Inc. ("Yield10" or the "Company") approved the full or partial furlough of approximately 65% of its workforce, most of whom are located in the Company's U.S. facility. During the furloughs, the furloughed employees will continue to receive employment benefits, and those employees who continue to work will receive reductions in compensation. The furloughs took effect on December 4, 2023, and will continue until such time as the Company is able to raise additional funding through public or private placements of equity or debt, technology licensing, collaboration arrangements or other strategic options undertaken with third parties.
In connection with the furloughs, the Company does not estimate that it will incur significant restructuring charges; however, costs that are not currently contemplated may occur as a result of the furloughs.

Also on November 30, 2023, Yield10's Board of Directors approved amendments to the employment agreements of the Company's chief executive officer, principal financial and accounting officer and its two other named executive officers. The amendments temporarily reduce the salary of each officer to $684 per week until such time as the Company is able to raise additional funding to support its ongoing operations. Executive officers of the Company will continue to receive employment benefits during the period of reduced salaries. If the Company is able to raise additional funding, the executive officers will receive payment of the amount of their salaries that was retained pursuant to these amendments.
The foregoing summary description of the amended employment agreements is not complete and is subject to, and qualified in its entirety by reference to, the full text of the amendments to the employment agreements, copies of which will be filed as exhibits to the Company’s Annual Report on Form 10-K for the fiscal year ended December 31, 2023.
