With the reverse takeover of the Garland Compton agency in 1975, they achieved a public company listing and were thereafter able to make rights issues to raise the capital required for their acquisition drive.

In 1960, the US agency, Compton Advertising, bought a minority holding so that they could build their own international network, primarily to service their largest client, Procter & Gamble.

Garland Compton was also a top 10 agency with big spending clients including Bass, British Caledonian, Gillette, New Zealand Dairy Board, Procter & Gamble, Schweppes and United Biscuits.

[6] This was a successful 13 years for Saatchi: a time when the agency produced admired creative work, and had an appetite for global business expansion.

Whilst their foundation London office was consistently successful in winning new clients, it too was propelled forward in the 1976 merger with the UK operation of the larger Garland-Compton business resulting in its tripling of size and a relocation into the Compton premises.

The initial shareholding was 15% Cannon Holdings (Quant & friends); 42% Charles; 38% Maurice; 2.5% John Hegarty; 2.5% Tim Bell.

[4] In the same month Maurice Saatchi met with board executives of the Hill Samuel merchant bank to discuss an acquisition.

[4] In June 1988, the company issued £176.5 million of convertible preference shares at £4.41 each to fund its acquisition of the Gartner Group, an information technology market research firm.

He maintained dialogue with his former employer, the State of Wisconsin Investment Board, which had built up an 8.1% holding during Herro's time there and with colleagues at the General Electric Capital Corporation, which held 5%.

Herro became concerned in 1992 at the negative effect on the investment of the public bickering between Scott and Maurice Saatchi and made this view known to the board along with his intention to monitor the business closely.

[11] At this time, Bob Seelert was brought in as CEO to stabilize the company,[12] and the acquisition frenzy that characterised the agency throughout the 1980s was taken to task under the new management system.

While the British Airways and Mars[13] defections in 1995 destabilised the agency's reputation in London, it seemed not to affect operations in its biggest market, the United States.

This was part of an imperative installed by Roberts, a beverage marketing veteran brought in to continue the revival of the agency's fortunes.

A significant decision of his was to move the global headquarters of the agency from its Charlotte Street, London address to its Hudson St, New York City office.

As a result, Roberts committed to building revenue through its existing clients, which led to additional assignments, with Saatchi Los Angeles securing new accounts such as Pur Filtered Water and Millstone Gourmet Coffee.

Efforts were also made to shore up the Los Angeles office after it missed a $US40 million brief for Toyota's Scion, a new sub-brand targeted at youth, which was given to San Francisco-based Attik, a hybrid creative agency.

[15] Despite these losses, this strategy gave rise to the Lovemarks philosophy – a theory espoused in a book by the same name released by Roberts.

While this was met with scepticism in the advertising world, Roberts was vindicated in 2006 when he secured nearly $US700 million worth of billings from two clients, Wendy's and department store JC Penney.

[16] In 2005, critics complained that in creating a £20 million campaign for a new Brazilian spirit the agency spray-painted graffiti images on walls and buildings in the East End of London.

In its defence, Saatchi released a statement indicating their regret of Dr Marten's decision to terminate their services with them but emphasising that they believed that the advertisement was deliberately edgy but not offensive.

While the addition of Wendy's and JC Penney to the American client roster reaffirmed Roberts' belief in the "ideas agency" model, the London office continued its slide as it plummeted out of the UK Top 10 list of agencies (a list, compiled by industry magazine Campaign UK, based on reported client billings).

While its London office, with a client list that includes Sony, Orange and Asda, has been consistently lauded for its new business and creative success, its Minneapolis headquarters, where namesake founder Pat Fallon remains a presence, has been tarnished by a number of client losses, including Citigroup, BMW, Sony, Dyson and Starbucks.

The new alliance, known as Saatchi & Saatchi-Fallon (SSF Group), will operate under the supervision of Kevin Roberts, who was named as CEO of the new entity.

After a year of operations, it was announced in October 2008 that the SSF Group had been contracted by chocolate giant Cadbury to handle its Dairy Milk and related brands across several markets (including the UK, Europe, Russia, Canada and the United States), with a reported total of $US200 million in billings.

Whilst Fallon London would lead creative efforts across Europe, Saatchi's New York office was handed the brief to handle the business in the United States, where Cadbury remains a relative unknown compared to its main competitor, Hershey.

In 2017, the global CEO Kevin Roberts left the agency after a controversy around comments that he made regarding women's equality in the advertising industry.

Following in the tradition of the staff-only pub; the company created a new onsite joint venture, again named 'The Pregnant Man' which is open to the public.

Along with Richard Meyers, it grew to become the most anticipated premiere at the Cannes Lions Festival, and featured directors such as Spike Jonze, Jonathan Glazer, Ellen von Unwerth, Kinka Usher, Floria Sigismondi, Mark Romanek, Michel Gondry, and Samuel Bayer.

The agency’s leading copywriter and a Full Board Director who in 1978 created the Labour Isn't Working campaign which was voted the Poster of the Twentieth Century, and is widely credited as being highly influential in Margaret Thatcher’s election victory in 1979.

Paul Arden (1940–2008) was an Executive Creative Director at the company between 1987 and 1995 working on British Airways, Anchor Butter, Toyota, Ryvita, Nivea, Trust House Forte, Alexon Group and Fuji among others.
