• For each YPF share currently held, each shareholder will receive 9 additional shares, totaling 10 shares
• The par value of each share will be adjusted from AR$10 to AR$1, and the total number of shares (rounded to millions) will be adjusted from 393.3 million to 3,933.1 million (the equivalent number of ADRs remained unchanged at 393.3 million)
• This will be an automatic transaction, so shareholders will not be required to take any action

The ADSs will not be affected by the stock split, except for an adjustment to their conversion ratio: each ADS will represent 10 Class D shares instead of 1.
