par value financial

"change in par value of the Shares"

Par value is the fixed amount printed on a bond or stock that represents its original value when issued. It’s like the face value of a coin or bill—what the issuer promises to pay back or the starting price of a stock—though it often doesn’t change with market prices. It matters because it helps determine certain financial details, like how much the company will pay back at maturity.

book-entry ordinary shares financial

"exchange of 393,312,793 book-entry ordinary shares with a par value"

share capital financial

"the Company’s share capital, following the aforementioned transactions, remains at"

Share capital is the total amount of money a company raises by selling pieces of itself, called shares, to investors. It’s like a company’s savings from many owners, which helps fund its growth and operations. This money matters because it shows how much the company has raised from shareholders and how it’s financed its business.

American Depositary Shares (ADSs) financial

"holders of ADSs issued pursuant thereto, except for an adjustment"

A U.S.-listed certificate that stands for a specific number of shares in a non‑U.S. company held by a U.S. bank, making the foreign stock tradable on American exchanges in dollars. Think of it like a local voucher that represents ownership of an overseas product — it lets U.S. investors buy and sell foreign companies without handling foreign currency or foreign brokerage accounts, but it can affect dividends, voting rights, fees, liquidity and exposure to currency and regulatory differences.

Amended and Restated Deposit Agreement financial

"no impact on the Amended and Restated Deposit Agreement dated March 9, 2022"

market liquidity financial

"reasons: (i) to improve the market liquidity of the Company’s shares"

FAQ

What share split is YPF (YPF) carrying out and when is it effective?

YPF is executing a 10-for-1 share split effective August 4, 2026. Shareholders of record on August 3, 2026 will see each ARS 10 ordinary share exchanged for ten ARS 1 ordinary shares without changing their economic interest or ownership percentage.

How do YPF (YPF) share counts and par value change after the split?

Outstanding ordinary shares will increase from 393,312,793 to 3,933,127,930, while par value per share drops from ARS 10 to ARS 1. Total share capital remains ARS 3,933,127,930, so the overall capital amount is unchanged by the split.

Does the YPF (YPF) share split affect shareholder ownership or economic value?

YPF states the split does not change any shareholder’s economic value or ownership percentage. Each investor will hold ten times more shares at one-tenth the par value, keeping their proportion of share capital and voting rights the same as before.

How will the YPF (YPF) share split impact ADS holders?

The split leaves the deposit arrangement in place but changes the ADS ratio from 1 Class D share per ADS to 10 Class D shares per ADS. This adjustment aligns ADSs with the new underlying share structure following the 10-for-1 split.

What reasons does YPF (YPF) give for implementing the share split?

YPF cites three reasons: to improve market liquidity on ByMA, to enhance access for retail investors by lowering par value per share, and to align its capital structure with standard market practices of comparable companies domestically and internationally.

Will YPF (YPF) settle fractional shares created by the split?

No. YPF notes that, under Bolsas y Mercados Argentinos S.A. listing rules, fractions of shares will not be settled. Only whole shares will be reflected in the updated book-entry records maintained by Caja de Valores S.A. after the split becomes effective.

Ref.: YPF S.A. – Split – Change in Par Value of the Shares. Notice pursuant to Articles 34 and 35 of the ByMA Listing Regulations.

Ladies and Gentlemen,

We are pleased to write to you on behalf of YPF S.A. (the “Company”) to inform you that for all shareholders of the Company who hold such status as of August 3rd, 2026, according to the registry maintained by Caja de Valores S.A., effective as of August 4th, 2026, the distribution of shares and the change in par value will take effect simultaneously (the “Split”). As of that time, the book-entry records of Caja de Valores S.A. will reflect the exchange of 393,312,793 book-entry ordinary shares with a par value of ARS 10 each for 3,933,127,930 book-entry ordinary shares with a par value of ARS 1 each and one vote per share. Accordingly, for each share with a par value of ARS 10 held by a shareholder, such shareholder will receive one share with a par value of ARS 1, as well as nine additional shares with a par value of ARS 1, for a total of ten shares with a par value of ARS 1.

We report that in accordance with the Listing Rules of Bolsas y Mercados Argentinos S.A., fractions of shares will not be settled.

Furthermore, we also report that the Company’s share capital, following the aforementioned transactions, remains at ARS 3,933,127,930, now represented by 3,933,127,930 book-entry common shares with a par value of ARS 1 each.

It is hereby noted that this change in the par value of the shares does not alter the economic value of the holdings or the percentage of ownership of the share capital and voting rights of any shareholder. Additionally, it is hereby reported that the Split will have no impact on the Amended and Restated Deposit Agreement dated March 9, 2022, entered into between the Company, The Bank of New York Mellon, acting as depositary, and the holders of ADSs issued pursuant thereto, except for an adjustment that will be necessary to the ratio of Class D shares represented by each ADS, changing from 1 (one) Class D share per ADS to 10 (ten) Class D shares per ADS.

Finally, it is hereby reported that the implementation of the Split is based on the following reasons: (i) to improve the market liquidity of the Company’s shares on the local market (ByMA); (ii) to facilitate accessibility for retail investors by reducing the par value per share and thereby allowing greater participation by small investors in the Company’s capital; and (iii) to implement standard market practices of comparable companies at the national and international levels.

Sincerely,

Margarita Chun
