Hii,
Yes, the first AGM of a company can be held within 18 months from the date of its incorporation but at the same time the provisions of section 210 are also to be taken into consideration wherein it is specifically given that profit and loss shall relate to the period beginning with the incorporation of the company and ending with a day which shall not precede the day of the meeting by more than nine months. Therefore, the first AGM should be held within 18 months but at the same time it is also to be ensured that the date of the meeting shall be such that though within 18 months, the accounts to be laid down in such meeting are not more than 9 months old.
For Example: if the financial year of the company ends on 31.03.2011 than the AGM can be held till 15.10.2011 in which case the accounts will not prceed the meeting by more than 9 months but suppose the company ends its financial year on 31.12.2010 than the AGM can not go beyond september in which case provisions of both the sections will be duly complied with as the AGM would be within 18 months as well as accounts will not be more than 9 months old.
