PART III — NARRATIVE

State below in reasonable detail why Forms 10-K, 20-F, 11-K, 10-Q, 10-D, N-SAR, N-CEN, or the transition report or portion thereof, could not be filed within the prescribed time period.

Fluor Corporation (“Fluor” or the “Company”) has determined that it is unable to file its Quarterly Report on Form 10-Q for the quarter ended September 30, 2020 (the “Q3 Form 10-Q”) within the prescribed period without unreasonable effort or expense. The Company has not yet filed its Form 10-Q for the quarter ended June 30, 2020 (the “Q2 Form 10-Q”) and does not anticipate being able to file the Q3 Form 10-Q until after the filing of the Q2 Form 10-Q. While there are no assurances as to timing, the Company expects to file the Q3 Form 10-Q before December 31, 2020.

PART IV — OTHER INFORMATION

(1)	Name and telephone number of person to contact in regard to this notification
	Joseph L. Brennan	469	398-7200
	(Name)	(Area Code)	(Telephone Number)
(2)	Have all other periodic reports required under Section 13 or 15(d) of the Securities Exchange Act of 1934 or Section 30 of the Investment Company Act of 1940 during the preceding 12 months or for such shorter period that the registrant was required to file such report(s) been filed? If answer is no, identify report(s).
			¨ Yes    x No
	Form 10-Q for the quarter ended June 30, 2020.
(3)	Is it anticipated that any significant change in results of operations from the corresponding period for the last fiscal year will be reflected by the earnings statements to be included in the subject report or portion thereof?
			¨ Yes    x No
	If so, attach an explanation of the anticipated change, both narratively and quantitatively, and, if appropriate, state the reasons why a reasonable estimate of the results cannot be made.
	For the third quarter of 2019, the Company reported a net loss attributable to Fluor of $783 million (as restated), or $5.58 per diluted share, reflecting a non-cash charge of $546 million related to establishing a valuation allowance against net deferred-tax assets, a non-cash impairment charge of $290 million related to the COOEC-Fluor joint venture fabrication yard, Stork, and the Sacyr-Fluor joint venture in Spain, and $44 million for restructuring activities. Until the Q2 Form 10-Q and the Q3 Form 10-Q are filed, the quarters ended June 30, 2020 and September 30, 2020 remain open. As a result, while the Company does not anticipate that the current fiscal year results will include charges of the magnitude reflected in the restated financial results for the quarter ended September 30, 2019, the Company is not currently able to anticipate whether, upon reporting of the financial information for the 2020 second and third quarters, there will be any significant change in results of operations for the period ending September 30, 2020 from the corresponding period for the last fiscal year.
	Cautionary Note Regarding Forward-Looking Statements This Form 12b-25 contains forward-looking statements within the meaning of Section 27A of the Securities Act of 1933 and Section 21E of the Securities Exchange Act of 1934, including, without limitation, Fluor’s expectations as to the filing of the Q2 Form 10-Q and Q3 Form 10-Q. These forward-looking statements involve risks and uncertainties, and actual results could vary materially from these forward-looking statements. Factors that may cause future results to differ materially from management’s current expectations include, among other things, the severity and duration of the COVID-19 pandemic and actions by governments, businesses and individuals in response to the pandemic, including the duration and severity of economic disruptions, and the risk that the completion and filing of the Q2 Form 10-Q and Q3 Form 10-Q will take longer than expected. Fluor disclaims any obligation to update information contained in these forward-looking statements whether as a result of new information, future events, or otherwise.
