Hasler remains the most under-pressure coach in the NRL after the opening 10 rounds, entering Sunday's clash against Canberra with a 3-6 record.
Last week's comeback win over Newcastle was particularly timely for the Titans, after it emerged the club could axe Hasler at year's end if they did not make finals.
But Mitchell this week launched an impassioned defence of the club's direction, while throwing his support behind the veteran coach.
"Des is here through 2026," Mitchell said.
"There has been media speculation, as there is and always is with coaches. We have a look at the merry-go-round going on at the NRL at the moment.
"We don't talk to players, recruitment, retention, staff or coaches. Des is here through 2026."
Asked whether he would have a chat with Kevin Walters around potentially signing the ex-Brisbane coach, Mitchell said: "We have no need".
The Titans CEO also insisted he was not feeling any heat in his own role, as the club locked in a new high-performance centre for Emerald Lakes from 2027.
Hasler is the Titans' fourth head coach since the start of 2017, with the club having only made the finals once in that time.
"We've made an NRLW grand final, we made the finals in 2021," Mitchell, who took over as CEO of the Titans in late 2018, said.
"We have a young NRL roster that is developing, we have a wonderful spine of players that is sitting there.
"We are looking at the composition of our squad through 2026, 2027 and 2028.
"Some fabulous pathways kids who played for their local homes and regions who are becoming elite level NRL players. I think we are on track.
"From a performance point of view sometimes you have to go sideways a bit to find your feet and go again. You don't get success overnight."
The Titans will get Keiran Foran back for Sunday's clash with the Raiders, named at No.14 but still some chance to start in the halves if AJ Brimson goes to fullback.
Foran has not played since the end of last season, with the veteran missing the start of this year with a biceps tear.
But Gold Coast have suffered a blow in their outside backs with centre Brian Kelly succumbing to a shoulder issue, leaving Tony Francis to come into the side.
