Stock-based Awards
For stock-based awards, the dilutive effect is calculated using the treasury stock method. Under this method, the dilutive effect is computed as if the awards were exercised at the beginning of the period (or at time of issuance, if later) and assumes the related proceeds were used to repurchase our common stock at the average market price during the period. Related proceeds include the amount the employee must pay upon exercise and the future compensation cost associated with the stock award. Approximately 13,000, 17,000, and 0.3 million stock-based awards were excluded from the calculation of diluted EPS for the years ended December 31, 2025, 2024, and 2023 because they were anti-dilutive. These stock-based awards could be dilutive in future periods.

Convertible Notes and Share Hedges

2021 Notes, Warrants and Call Option Transactions
For our convertible notes issued in March 2021 (the 2021 Notes), the dilutive effect is calculated using the if-converted method. We are required, pursuant to the indenture governing the notes, to settle the principal amount in cash and may elect to settle the remaining conversion obligation (stock price in excess of conversion price) in cash, shares, or a combination thereof. Under the if-converted method, we include the number of shares required to satisfy the remaining conversion obligation, assuming all the notes were converted. The average quarterly closing prices of our common stock for the year ended December 31, 2025 were used as the basis for determining the dilutive effect on EPS. For the three months ended September 30, 2025, the quarterly average closing prices for our common stock exceeded the conversion price of $126.00 and, this being the only period in which the average closing price of our common stock exceeded the conversion price, a weighted average of the quarterly results from the dilutive effect of convertible notes is computed and has been reflected in the table above for the year ended December 31, 2025.

In conjunction with the issuance of the 2021 Notes, we sold warrants to purchase 3.7 million shares of Itron common stock. The warrants have a strike price of $180.00 per share. For calculating the dilutive effect of the warrants, we use the treasury stock method. With this method, we assume exercise of the warrants at the beginning of the period, or at time of issuance if later, and the issuance of common stock upon exercise. Proceeds from the exercise of the warrants are assumed to be used to repurchase shares of our stock at the average market price during the period. The incremental shares, representing the number of shares assumed to be exercised with the warrants less the number of shares repurchased, are included in diluted weighted average common shares outstanding. For periods where the warrants strike price of $180.00 per share is greater than the average share price of Itron stock for the period, the warrants would be anti-dilutive. For the year ended December 31, 2025, the quarterly average closing prices of our common stock did not exceed the warrant strike price, and therefore 3.7 million shares were considered anti-dilutive for U.S. GAAP.

In connection with the issuance of the 2021 Notes, we entered into privately negotiated call option contracts on our common stock (the 2021 call option transactions) with certain commercial banks. The 2021 call option transactions cover, subject to anti-dilution adjustments substantially similar to those in the 2021 Notes, approximately 3.7 million shares of our common stock, the same number of shares initially underlying the notes, at a strike price of approximately $126.00, subject to customary adjustments. The 2021 call option transactions will expire upon the maturity of the 2021 Notes, subject to earlier exercise or termination. Exercise of the 2021 call option transactions would reduce the number of shares of our common stock outstanding and therefore would be anti-dilutive.

2024 Notes and Capped Call Transactions
For our convertible notes issued in June 2024 (the 2024 Notes), the dilutive effect is calculated using the if-converted method. We are required, pursuant to the indenture governing our convertible notes, to settle the principal amount of the convertible notes in cash and may elect to settle the remaining conversion obligation (stock price in excess of conversion price) in cash, shares, or a combination thereof. Under the if-converted method, we include the number of shares required to satisfy the remaining conversion obligation, assuming all the convertible notes were converted. The average quarterly closing prices of our common stock for the year ended December 31, 2025 were used as the basis for determining the dilutive effect on EPS. The quarterly average closing prices for our common stock did not exceed the conversion price of $131.24, and therefore all associated shares were anti-dilutive.

In connection with the issuance of the 2024 Notes, we entered into privately negotiated capped call transactions (the 2024 capped call transactions) on our common stock with certain commercial banks. The 2024 capped call transactions cover, subject to anti-dilution adjustments substantially similar to those in the 2024 Notes, approximately 6.1 million shares of our common stock, the same number of shares initially underlying the convertible notes, at a strike price of approximately $131.2353, subject to customary adjustments. The cap price of the 2024 capped call transactions will initially be $205.86 per share, which represents a premium of 100% over the last reported stock price per share of the Company's common stock on June 17, 2024,
and is subject to certain adjustments under the terms of the 2024 capped call transactions. The 2024 capped call transactions will expire upon the maturity of the 2024 Notes, subject to earlier exercise or termination. Exercise of the 2024 capped call transactions would reduce the number of shares of our common stock outstanding and therefore would be anti-dilutive.

About Earnings Per Share Disclosures

The earnings per share disclosure breaks down the calculation from net income to both basic and diluted EPS, revealing the full impact of a company's capital structure on per-share economics. The reconciliation between basic and diluted share counts exposes how many stock options, RSUs, convertible securities, and warrants are potentially dilutive to existing shareholders.

Key signals: a widening gap between basic and diluted shares indicates growing dilution from equity compensation or convertible instruments. Anti-dilutive securities excluded from the diluted calculation deserve attention — they represent latent dilution that will materialize if the stock price rises. Watch for the effect of share buybacks on per-share metrics: EPS growth driven primarily by repurchases rather than income growth signals weakening fundamentals. Compare year-over-year changes in the diluted share count against equity compensation expense to assess whether management is effectively managing dilution.
