The results of operations for the three and six months ended June 30, 2025 are not necessarily indicative of the results that can be expected for the entire fiscal year ending December 31, 2025.

An allowance for credit losses is established based on TEC’s collection experience and reasonable and supportable forecasts that affect the collectibility of the reported amount. Circumstances that could affect TEC’s estimates of credit losses include, but are not limited to, customer credit issues, generating fuel prices, customer deposits and general economic conditions. Accounts are reserved in the allowance or written off once they are deemed to be uncollectible.
