Does the company currently pay a cash dividend?
Tenet has not paid a cash dividend since 1993. Instead, the company reinvests its profits in its hospitals and services. We believe this is the best means to serve our shareholders over the long term.

I have old NME stock certificates. Do I need to exchange them for Tenet shares?
NME changed its name to Tenet in 1995, after completing the acquisition of AMI. Your NME certificates are still valid; you are not required to exchange them for Tenet stock certificates. However, we do recommend keeping records up to date. If you choose to exchange your NME certificates for Tenet certificates, you may do so through Computershare.

I have old AMI stock certificates. Do I need to exchange them for Tenet shares?
Yes. On March 1, 1995, NME acquired American Medical Holdings ("AMI") and renamed the combined company Tenet Healthcare Corporation. As a result of the acquisition, each share of AMI stock was converted into the right to receive 0.42 of a share of Tenet stock and $19.00 in cash. There is no longer a market for AMI shares.

I have old OrNda stock certificates. Do I need to exchange them for Tenet shares?
In January 1997, OrNda was acquired by Tenet Healthcare Corporation. As a result of that acquisition, each share of OrNda was converted into the right to receive 1.35 shares of Tenet stock. There is no longer a market for your OrNda shares.

The cash and Tenet stock to which you are entitled was turned over to the appropriate state authorities under the abandoned property laws.

Please contact the states in which you resided in prior to 1997.

I have old Summit stock certificates. Do I need to exchange them for Tenet shares?
Summit Health Ltd. was acquired by OrNda and subsequently acquired by Tenet in January 1997. As a result of the acquisition, each share of Summit stock was converted into the right to receive 0.291195 of a share of Tenet stock and $5.50 in cash. There is no longer a market for your Summit shares.

I have old American Medical Holdings (AMI) stock certificates. Do I need to exchange them for Tenet shares?
On March 1, 1995, NME (now Tenet Healthcare Corporation) acquired American Medical Holdings ("AMI"). As result of the acquisition, each share of AMI stock was converted into the right to receive $25.51 per AMI share, $19.00 in cash plus $6.51 of NME stock (0.42 shares x $15.50 per share = $6.51). There is no longer a market for your AMI shares.
