The announcement was made shortly before the chancellor was expected to reveal a partial U-turn on business rates changes facing pubs.
The industry said they were expected to add almost £13,000 in costs over three years to the average pub in advance of the climbdown.
It has battled rising costs for many years, with new minimum pay levels and heightened national insurance contributions adding to the burden last spring.
Revel undertook a major restructuring in 2024, shutting 15 unprofitable bars in a bid to turn around its performance.
But the revamp fell flat and a strategic review resulted in the group being placed up for sale.
Revel had partly blamed weak trading, with younger customers having little disposable income. Higher costs also weighed on its bottom line and growing debt pile.
The incident happened in Wythenshawe last March, Greater Manchester Police said.
He has also been charged with causing death by driving unlicensed and causing death by driving uninsured. The boy cannot be named for legal reasons.

The mammoth seizure weighed nearly as much as a school bus and the sub was 230 nautical miles from the Azores when it was intercepted.
The semi-submersible eventually sank before authorities could take all its cargo, sending 35 of the 300 packages to the bottom of the Atlantic.
Portuguese police led the operation, assisted by authorities in the UK and US.
The nearly nine-tonne cargo is "the biggest seizure of cocaine ever in Portugal", a police spokeswoman told AFP news agency.
The boat came from Latin America and had three Colombians and a Venezuelan on board, police said.
"Inside the vessel - 300 bales of cocaine were being transported," they added.
Such vessels have been dubbed "narco subs", with cartels using them to try to smuggle drugs undetected.
Sky News' Alistair Bunkall last year reported on the tactics being used by smugglers off the Iberian peninsula and how, in November, Portuguese security intercepted the kind of narco submarine that is rarely discovered.
Narco subs had previously been used to ferry drugs north from Colombia to central America and Mexico.
But traffickers have been setting their sights further and using them to sail across the Atlantic and Pacific.

Last March, police said officers had confiscated more than six tonnes of cocaine from a semi-submersible off the Azores while bound for the Iberian peninsula.
The UK's National Crime Agency played a role in that bust - alongside the US Drug Enforcement Administration and the Spanish Guardia Civil.
In 2023, a sub with two dead bodies and nearly three tonnes of cocaine aboard was seized off the coast of Colombia.
Dame Esther told Mornings With Ridge And Frost she has accepted "there is no cure" for her condition, but said treatment had "delayed" her cancer by three years.
The TV star, who was a household name in the 1970s and '80s as host of the BBC's That's Life, joined Dignitas the same year she was diagnosed in 2023, labelling the laws governing assisted dying at the time as "a mess".
As a supporter of new legislation, she said The Terminally Ill Adults (End of Life) Bill, commonly known as the Assisted Dying Bill and making its way through parliament, "would never have happened [become law] in time for me anyway".
Dame Esther added: "So I've always been really fighting for future generations that they will have the choice if they are terminally ill."
She accused the House of Lords of "behaving very strangely", suggesting the bill's passage was being held up by "very vocal" lobby groups who would never be satisfied with proposed amendments and are "opposed to the whole concept in principle".
Pointing to "some of the disability groups, some of the religious groups", she said they were "filibustering and using every method they can to obstruct what the House of Commons has already passed and what the public is a large majority in favour of, because it gives us the dignity of choice".
Dame Esther said it was time the House of Lords "looked very carefully at that democratic duty. This is not the way we run things in this country. We don't get small lobby groups of minorities objecting in principle, and therefore frustrating the Democratic will of the public. And the Commons".
She was speaking as the NHS announced it was extending a pilot scheme using AI and robotics to improve early detection of the UK's third most common cancer, which Dame Esther called "a very hopeful sign that things are really radically changing when it comes to the treatment of cancer".
Since NHS England started its screening programme in 2019, more than 1.5 million people who have ever smoked have been invited to have their lung health checked, but only if aged between 55 and 74.
But the Childline founder, who revealed she is not being treated currently, said she did not understand the programme's apparent upper age limit, as "75 is the new 55, so I don't know why people like me at 85 have been ruled out completely on the grounds that we're past it and we should be grateful for what we got. They [ministers] might have a look at that".

King's 'good news' on cancer
More than 49,000 people are diagnosed with lung cancer each year, and Dame Esther said she understood "what it's like if they can't treat you".
She said: "But this is on the basis that they can treat you early, and they can stop it spreading, and they can make a difference to your life expectancy. So I welcome it, of course, for other people."
The government has been under pressure to act after changes made in the budget in November, alongside the end of support from the pandemic, meant businesses - and especially pubs - were set to face huge increases in their business rates in April.
This, coupled with a hike in the minimum wage and an increase in employer national insurance contributions, led businesses to warn that hundreds of pubs and venues could close without an intervention.
Now Treasury minister Dan Tomlinson has announced that there will be a temporary support package for pubs - but nothing for restaurants, soft play centres and cafes.
Announcing the changes, he said: "Pubs are the cornerstone of so many communities, they are essential to the social and cultural life of so many places across the country."
Mr Tomlinson told the Commons that from April, every pub in England will get 15% off its new business rates bill. Bills will then be frozen in real terms for a further two years.
Business rates are a tax based on an estimate of a commercial property's rental value.
The changes will be worth £1,650 for the average pub over the next year, the minister added - before insisting that around three-quarters of pubs will see their bills fall or stay the same.
The support will also apply to music venues, but not recording studios and other hospitality venues.
He explained: "Many live music venues are valued as pubs and many pubs are grassroots live music venues. It would not be right to seek to draw the line so tightly so as to include some and not others."

Mr Tomlinson also told MPs that the government will launch a review into how pubs are valued, and will allow them to stay open until 1am or 2am for later stage home nation matches during the World Cup this summer, which is being played in North America.
The minister added that the government will consult on loosening planning rules for pubs, allowing them to extend their main room or add guest rooms without planning applications.
Recognising that "it's a tough time for other businesses on the high street", he pointed to an upcoming High Streets Strategy, along with previous financial support for companies.
Chancellor Rachel Reeves was not present in the Commons and did not lay out the changes, despite being in the chamber earlier on Tuesday.
'Support must be permanent'
Responding to his statement, shadow chancellor Sir Mel Stride asked: "Is that it?"
Ms Reeves's Conservative opposite number continued: "After all this time, after weeks of telling our local pubs that help was on the way, this is all they get - a temporary sticking plaster that will only delay the pain for a few, while thousands of businesses despair as their bills skyrocket.
"Support must be permanent. We have to cut business rates for our high streets to give certainty to local businesses, and it must be far wider than what the government has announced today, not just pubs, but the whole of the retail, hospitality and leisure sectors which bring life to our high streets and town centres."
Meanwhile, the Liberal Democrats labelled it a "half-hearted U-turn" and called on ministers to "apologise to publicans for the months of uncertainty and worry they forced on them".
Daisy Cooper, the party's Treasury spokesperson, added: "The government must do the right thing and press ahead with the full 20p discount it promised to every retail, hospitality and leisure business, and back our call for an emergency VAT cut for hospitality until April 2027 to save the great British high street."
'Restaurants and hotels facing severe challenges'
UKHospitality said the minister's announcement was "welcome" and showed the government has "listened to us about the acute cost challenges facing businesses".
But Kate Nicholls, the group's chair, added: "The rising cost of doing business and business rates increases is a hospitality-wide problem that needs a hospitality-wide solution.
"The reality remains that we still have restaurants and hotels facing severe challenges from successive budgets. They need to see substantive solutions that genuinely reduce their costs. Without that clear action, they will face increasingly tough decisions on business viability, jobs and prices for consumers."
'This is pure discrimination'
Tom Kiehl, the chief executive of UK Music, told Sky News that the government "must not forget recording studios".
He explained: "Why should the studio used to film Hamnet be entitled to business rate relief, yet the studio used to record the soundtrack not be eligible? This is pure discrimination and recording studios must not be treated as poor cousins in the creative economy. The government must think again."
'The government must honour its promise of root-and-branch reform'
The British Chambers of Commerce responded that the announcement is "good news for pubs and music venues" but added that it "does not go far enough to protect many other businesses which are under huge pressure".
Helen Dickinson, the chief executive of the British Retail Consortium said support should be " targeted at all those on the high street whose bills will see the biggest rises, whether they are pubs, shops or cafes".
