EARNINGS (LOSS) PER SHARE | NOTE 10—EARNINGS (LOSS) PER SHARE Earnings per share (“EPS”) is not presented retrospectively for periods prior to the issuance of the tracking stock as the tracking stock was not a part of the Company’s capital structure during those periods and the issuance of the tracking stock changes the common shareholders’ relative residual interest in the Company. Therefore, EPS is presented for the Company’s single class of common stock up to the time the tracking stock was issued and, subsequent to this date, EPS is presented prospectively under the two-class method. The computation of basic and diluted EPS is shown on the following page: (In thousands, except per share amounts) Three months ended September 30, Nine months ended September 30, 2024 2023 2024 2023 Earnings (loss) attribution Single class of common stock (through 6/20/2023) * $ N/A $ N/A $ N/A $ 31,382 Class A common stock (1,245) 17,288 2,085 18,616 Class A restricted stock awards 52 721 282 824 Class B common stock 507 1,395 4,079 1,395 Class B restricted stock awards 9 58 152 58 Forfeitable dividends declared on unvested stock-based awards 438 — 736 — Net income (loss) $ (239) $ 19,462 $ 7,334 $ 52,275 * Common stock and restricted stock participated in earnings 1:1 and are shown on a combined basis through 6/20/2023 consistent with historical presentation Three months ended September 30, 2024 Nine months ended September 30, 2024 Class A Class B Class A Class B 2024 EPS calculations Numerator Net earnings (loss) $ (1,245) $ 507 $ 2,085 $ 4,079 Denominator Weighted average shares used to compute basic earnings per share 43,378 8,684 42,827 8,574 Dilutive effect of stock option awards — 85 172 91 Dilutive effect of restricted stock units — 35 64 31 Dilutive effect of performance stock units — 166 283 159 Weighted average shares used to compute diluted earnings per share 43,378 8,970 43,346 8,855 Earnings (loss) per common share (dual-class structure) Basic $ (0.03) $ 0.06 $ 0.05 $ 0.48 Diluted $ (0.03) $ 0.06 $ 0.05 $ 0.46 Three months ended September 30, 2023 June 21 - September 30, 2023 Jan. 1 - June 20, 2023 Class A Class B Class A Class B YTD 2023 Single Class 2023 EPS calculations (single class of common stock through 6/20/2023) Numerator Net earnings $ 17,288 $ 1,395 $ 18,616 $ 1,395 $ 31,382 Denominator Weighted average shares used to compute basic earnings per share 42,144 8,432 42,044 8,412 44,344 Dilutive effect of stock option awards 352 103 339 97 381 Dilutive effect of restricted stock units 85 49 62 41 — Dilutive effect of performance stock units 302 102 263 92 27 Weighted average shares used to compute diluted earnings per share 42,883 8,686 42,708 8,642 44,752 Earnings per common share (single class of common stock) Basic $ 0.41 $ 0.17 $ 0.44 $ 0.17 $ 0.71 Diluted $ 0.40 $ 0.16 $ 0.44 $ 0.16 $ 0.70 Unvested restricted stock awards have the right to receive nonforfeitable dividends on the same basis as common shares; therefore, unvested restricted stock is considered a participating security for the purpose of calculating EPS. Prior to the initial distribution of Class B common stock in the second quarter of 2023, the Company showed EPS for its common stock and unvested restricted stock on a combined basis since both instruments participate on the same basis and the resulting EPS is typically the same. Starting under the two-class method, the Company reports separately the net earnings allocated away from holders of Class A and Class B common stock to holders of unvested restricted stock awards. For accounting purposes, Class B’s participation rights in net earnings are, in substance, discretionary based on the power of the Company’s Board of Directors to add or modify expense allocation policies, redefine CORE assets, and redetermine CORE’s per-ton usage fees at any time, in its sole discretion, without shareholder approval. Therefore, no amount of the Company’s net earnings shall be allocated to Class B for the purpose of calculating EPS other than actual dividends declared during the period for the tracking stock. However, during the three months and nine months ended September 30, 2024, dividends declared by the Company were in excess of consolidated net income (loss) for the period, which resulted in an undistributed net loss for reporting purposes. The resulting undistributed net loss was allocated proportionately between outstanding Class A and Class B common stock based on the rights to residual net assets upon liquidation being equal between holders of Class A and Class B common stock. For the nine months ended September 30, 2024, three dividends were declared for Class B common stock while only two dividends were declared for Class A common stock due to the timing of declaration. Diluted EPS is calculated using the treasury stock method for stock options and restricted stock units. For performance stock units, the awards are first evaluated under the contingently issuable shares guidance, which requires a determination as to whether shares would be issuable if the end of the reporting period were the end of the contingency period. For shares determined to be issuable under performance stock unit awards, the treasury stock method is then applied to determine the dilutive impact of the awards, if any. Unvested restricted stock awards are considered potential common shares as well as participating securities, as discussed previously, and are included in diluted EPS using the more dilutive of the treasury stock method or the two-class method. Since these awards share in dividends on a 1:1 basis with common shares, applying the treasury stock method is antidilutive compared to the basic EPS calculation that allocates earnings to participating securities under the two-class method discussed previously. For the three months ended September 30, 2024, diluted EPS for Class A Common stock excluded all outstanding awards of potential common stock because of the allocated net loss discussed above, and, therefore, the inclusion of any potential common shares would be antidilutive. Excluded Class A common stock awards were 649 thousand options to purchase Class A common stock, 718 thousand RSUs, and 1,057 thousand PSUs (at target). For the nine months ended September 30, 2024, diluted EPS for Class A common stock excluded only the RSUs and PSUs granted in the first quarter of 2024, as discussed in Note 6, because the effect would have been antidilutive under the treasury stock method or, in the third quarter, because of the evaluation of such PSUs under the guidance for contingently issuable shares. No potential common shares were excluded from the calculation of diluted EPS for Class B common stock. For the third quarter of 2023 and the period from June 21,2023 through September 30, 2023, diluted EPS for Class A common stock excluded 166 thousand RSUs because the effect would have been antidilutive under the treasury stock method. Class A diluted EPS for these periods also excluded outstanding PSUs originally granted in 2022, or approximately 153 thousand units if September 30, 2023 were the end of the contingency period, because the effect would have been antidilutive under the treasury stock method. The same PSUs, or 249 thousand units at target, were excluded in the second quarter of 2023 based on the guidance for contingently issuable shares. For the third quarter of 2023 and the period from June 21, 2023 through September 30, 2023, diluted EPS for Class B common stock excluded certain PSUs, or approximately 31 thousand units if September 30, 2023 were the end of the contingency period, because the effect would have been antidilutive under the treasury stock method. The same awards, or 50 thousand units at target, were excluded in the second quarter of 2023 based on the guidance for contingently issuable shares. Diluted EPS for the single class of common stock existing from January 1, 2023 through June 20, 2023, excluded all outstanding RSUs, or 684 thousand units in total, because the effect would have been antidilutive under the treasury stock method. In addition, diluted EPS for the single class of common stock during this period excluded outstanding PSUs originally granted in 2022, or 249 thousand units at target, based on the guidance for contingently issuable shares. |
