Note 10—Earnings (Loss) Per Share The computations of basic and diluted earnings or loss per share were as follows (in millions, except per share data): | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Three months ended September 30, | | | Nine months ended September 30, | | | | 2026 | | 2025 | | | 2026 | | 2025 | | | | Basic | | Diluted | | Basic | | Diluted | | | Basic | | Diluted | | Basic | | Diluted | | Numerator for earnings (loss) per share | | | | | | | | | | | | | | | | | | | | | | | | | | | Net income (loss) | | $ | 26 | | $ | 26 | | $ | (1,923) | | $ | (1,923) | | | $ | 267 | | $ | 267 | | $ | (2,940) | | $ | (2,940) | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Denominator for earnings (loss) per share | | | | | | | | | | | | | | | | | | | | | | | | | | | Weighted-average shares outstanding | | | 1,120 | | | 1,120 | | | 961 | | | 961 | | | | 1,116 | | | 1,116 | | | 911 | | | 911 | | Effect of share-based awards | | | — | | | 7 | | | — | | | — | | | | — | | | 8 | | | — | | | — | | Effect of warrants | | | — | | | — | | | — | | | — | | | | — | | | 2 | | | — | | | — | | Weighted-average shares for per share calculation | | | 1,120 | | | 1,127 | | | 961 | | | 961 | | | | 1,116 | | | 1,126 | | | 911 | | | 911 | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Earnings (loss) per share | | $ | 0.02 | | $ | 0.02 | | $ | (2.00) | | $ | (2.00) | | | $ | 0.24 | | $ | 0.24 | | $ | (3.23) | | $ | (3.23) | |
We excluded from the computations certain shares issuable as follows because the effect would have been antidilutive (in millions): | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Three months ended | | Nine months ended | | | | | | | | | | | | | | | | | September 30, | | September 30, | | | | | | | | | | | | | | | | | 2026 | | 2025 | | 2026 | | 2025 | | Convertible debt instruments | | | | | | | | | | | | | | | | 75 | | | 88 | | | 75 | | | 109 | | Share-based awards | | | | | | | | | | | | | | | | 3 | | | 15 | | | 3 | | | 16 | | Warrants (a) | | | | | | | | | | | | | | | | — | | | — | | | — | | | — | |
| (a) | For the three and nine months ended September 30, 2025, the warrants were antidilutive since the exercise price was greater than the average price for our shares. | |
