Rhea-AI Filing Summary

Form 4 filing synopsis: Tecogen Inc. (TGEN) director Earl R. Lewis was granted 25,000 non-qualified stock options on 07/24/2025 at an exercise price of $8.35 per share. The award vests 25 % each year and carries a 10-year term, expiring 07/24/2035. No common shares were bought or sold and no cash changed hands at the time of grant.

After this transaction, Lewis holds 91,250 derivative securities (options) in total, all recorded as direct ownership. The filing represents routine equity compensation aimed at aligning the director’s incentives with long-term shareholder value. Because the transaction involves options rather than immediate share issuance, near-term cash flow and ownership percentages are unaffected; any dilution would occur only if the options are exercised in the future.

Lewis, ha ricevuto in data 24/07/2025 25.000 opzioni su azioni non qualificate con un prezzo di esercizio di 8,35 $ per azione. Il premio matura al 25% ogni anno e ha una durata di 10 anni, con scadenza il 24/07/2035. Non sono state acquistate o vendute azioni ordinarie e non è stato scambiato denaro al momento dell’assegnazione.

Il deposito rappresenta una normale compensazione azionaria finalizzata ad allineare gli incentivi del direttore con il valore a lungo termine per gli azionisti. Poiché la transazione riguarda opzioni e non l’emissione immediata di azioni, i flussi di cassa a breve termine e le percentuali di proprietà non sono influenzati; eventuali diluizioni si verificherebbero solo se le opzioni venissero esercitate in futuro.

Lewis, recibió el 24/07/2025 25,000 opciones sobre acciones no calificadas con un precio de ejercicio de $8.35 por acción. La concesión se consolida un 25% cada año y tiene un plazo de 10 años, expirando el 24/07/2035. No se compraron ni vendieron acciones comunes ni se intercambió efectivo en el momento de la concesión.

Form 4 제출 요약: Tecogen Inc.(TGEN) 이사 Earl R. Lewis는 2025년 7월 24일에 주당 $8.35의 행사가격으로 25,000개의 비자격 스톡옵션을 부여받았습니다. 이 보상은 매년 25%씩 베스팅되며 만료일은 2035년 7월 24일로 10년의 기간을 가집니다. 보상 시점에 보통주 매매나 현금 거래는 없었습니다.

이번 거래 후 Lewis는 총 91,250개의 파생 증권(옵션)을 보유하고 있으며 모두 직접 소유로 기록되어 있습니다. 이번 제출은 이사의 인센티브를 장기 주주 가치와 일치시키기 위한 일상적인 주식 보상입니다. 이 거래는 즉시 주식 발행이 아닌 옵션 부여이므로 단기 현금 흐름이나 소유 비율에는 영향을 주지 않으며, 희석 효과는 옵션이 미래에 행사될 경우에만 발생합니다.

Résumé du dépôt du formulaire 4 : Le directeur de Tecogen Inc. (TGEN), Earl R. Lewis, s’est vu attribuer le 24/07/2025 25 000 options d’achat d’actions non qualifiées à un prix d’exercice de 8,35 $ par action. La récompense est acquise à hauteur de 25 % chaque année et a une durée de 10 ans, expirant le 24/07/2035. Aucune action ordinaire n’a été achetée ou vendue et aucun échange d’argent n’a eu lieu au moment de l’attribution.

Après cette transaction, Lewis détient au total 91 250 titres dérivés (options), tous enregistrés en tant que propriété directe. Le dépôt représente une compensation en actions habituelle visant à aligner les incitations du directeur avec la valeur à long terme pour les actionnaires. Comme la transaction concerne des options plutôt qu’une émission immédiate d’actions, les flux de trésorerie à court terme et les pourcentages de propriété ne sont pas affectés ; toute dilution ne surviendrait que si les options étaient exercées à l’avenir.

Insights

TL;DR: Routine option grant; neutral on valuation, marginal future dilution risk.

The grant of 25,000 options to Director Earl R. Lewis is standard board compensation. The strike price of $8.35 sets a hurdle that must be surpassed for intrinsic value, promoting long-term alignment. Post-grant holdings rise to 91,250 options, but no immediate share issuance or insider buying/selling occurred, so trading sentiment and liquidity remain unchanged. Potential dilution is minor and deferred until exercise, leaving current EPS and free float intact. Overall, the filing is informational with neutral investment impact.
