<P STYLE="font: 10pt Arial, Helvetica, Sans-Serif; margin: 9.75pt 0">CALGARY, June 16, 2017 /CNW/ - TransAlta Corporation (&quot;TransAlta&quot;
or the &quot;Company&quot;) (TSX: TA; NYSE: TAC) announced today that after having taken into account all election notices received
by the June 15, 2017 deadline for the conversion of the Cumulative Redeemable Rate Reset Preferred Shares, Series C (the &quot;Series
C Shares&quot;) into Cumulative Redeemable Floating Rate Preferred Shares, Series D (the &quot;Series D Shares&quot;), there were
827,628 Series C Shares tendered for conversion, which is less than the one million shares required to give effect to conversions
into Series D Shares. As a result, none of the Series C Shares will be converted into Series D Shares on June 30, 2017.</P>
