"Reference is made to the enclosed SPA, by which D.________ GmbH committed to buy an additional 2.5 % of the participation in N.________ AG from A.________ AG for a purchase price of CHF 4.25 million by end of July 2019 (see Article 8). We suggest July 12th 2019 as closing date for this transaction. Please kindly confirm if this suits." Darauf antwortete G.________ am 9. Juli 2019 wie folgt (act. 1/18): "Sorry for the late reply. The 12th July won't really work for me. I have instructed the closing to take place the 25th July. Hope this works for you."
