What the changes say

  • Supply-chain tariffs, tax-credit eligibility, and competitive bidding add new threats to utility construction and ownership.
  • Customer concentration shifted: no customer exceeds 10% of consolidated revenue, but Plastics remains concentrated.
  • EPA coal-emissions rules are now described as requiring reductions tied to each facility’s remaining operating life.
  • PVC resin risk now emphasizes inability to pass cost increases through promptly, potentially affecting margins and liquidity.

What changed since the prior 10-K

New

  • NewOPERATIONAL RISKS

    We are subject to risks associated with our supply chain and trade regulations and tariffs

    Supply disruptions and tariffs on coal, gas, metals, PVC resin, and renewable components could raise costs, delay projects, or limit capital recovery.

  • NewFINANCIAL RISKS

    Changes in tax laws, or failures to comply with tax credit eligibility requirements, could materially affect our financial condition and operating results

    Tax-law changes or failure to qualify for, transfer, or sell tax credits could weaken generation-project economics and liquidity.

  • NewFINANCIAL RISKS

    Regulatory requirements to competitively bid capital projects could impact our ability to construct and own utility assets. A lack of direct ownership of such investments could impact our ability to achieve our strategic financial goals and adversely impact our operating results

    Competitive-bidding rules could prevent OTTR from owning utility assets, while inflation may limit investment recovery, allowed returns, and future capital spending.
