Leonardo DRS, Inc.

From time to time, we are subject to certain legal proceedings and claims in the ordinary course of business. These matters are subject to many uncertainties, and it is possible that some of these matters ultimately could be decided, resolved or settled in a manner adverse to us. Although the precise amount of liability that may result from these matters is not ascertainable, we believe that any amounts exceeding our recorded accruals should not materially adversely affect our financial condition or liquidity. It is possible, however, that the ultimate resolution of those matters could result in a material adverse effect on our results of operations and/or cash flows from operating activities for a particular reporting period. We establish reserves for specific legal matters when we determine that the likelihood of an unfavorable outcome is probable and the loss is reasonably estimable. The Company reviews the developments in contingencies that could affect the amount of the reserves that have been previously recorded. The Company adjusts provisions and changes to disclosures accordingly to reflect the impact of negotiations, settlements, rulings, advice of legal counsel, and updated information. Significant judgment is required to determine both the probability and the estimated amount of any potential losses.

Some environmental laws, such as the Comprehensive Environmental Response, Compensation and Liability Act of 1980 (also known as “CERCLA” or the “Superfund law”) and similar state statutes, can impose liability upon former owners or operators for the entire cost of investigating and remediating contaminated sites regardless of the lawfulness of the original activities that led to the contamination. In July 2000, an entity which later became a subsidiary of the Company received a Section 104(e) Request for Information (“RFI”) from the National Park Service (“NPS”), pursuant to CERCLA, regarding the presence of radioactive material at a site within a national park, (“Orphan Mine”), which site was operated by an alleged predecessor to our subsidiary over 50 years ago. Following our subsidiary’s response to the RFI, the NPS directed it and another alleged former operator to perform an Engineering Evaluation and Cost Analysis (“EE/CA”) of a portion of the site. Our subsidiary made a good faith offer to conduct an alternative EE/CA work plan, but the NPS rejected this offer and opted to perform the EE/CA itself. The NPS previously posted its intention to open a formal public comment period regarding the EE/CA at the end of 2019. To our knowledge, the EE/CA has not been released and a public comment period has yet to be opened.

The Environmental Protection Agency (“EPA”) episodically updates its electronic databases concerning pending Superfund sites. As of June 2023, the entry in EPA’s Superfund database for this site states that this “[s]ite does not qualify for the NPL [National Priorities List] based on existing information. The EPA has determined that no further federal action (NFFA) will be taken at this site.” As a result, DRS has eliminated the Orphan Mine reserve as a liability is no longer probable or estimable. However, it remains possible that the NPS may seek to recover damages, including for remediation and/or loss of use of certain natural resources. We believe that we have legitimate defenses to our subsidiary’s potential liability and that there are other potentially responsible parties for the environmental conditions at the site, including the U.S. government as owner, operator and arranger at the site. The potential liability associated with this matter could change substantially due to such factors as additional information on the nature or extent of contamination, methods of remediation that might be recommended or required, changes in the apportionment of costs among the responsible parties, whether the NPS seeks to recover additional damages, whether the NPS’s plans to investigate additional areas to identify a need for further remedial action for which the Company may be identified as a potentially responsible party, and other actions by governmental agencies or private parties.
