The Meath man’s Venus Lucia Productions Ltd saw accumulated profits rise from £238,763 to £1.036m (€1.2m) in the 12 months to the end of July 31.
The staggering 335% jump coincided with the cash pile at the Bafta award-winning comedian’s company last year increasing from some £324,568 to £1.167m.
The abridged accounts disclose revenues generated by the firm in the year totalled £1.027m.
The two directors of the firm are Moran and his wife, Elaine, who works as a script editor.
The performance by the firm is in contrast to its 2011 results, when accumulated profits sharply dropped from £358,004 to £238,763 with cash decreasing from £513,066 to £324,568.
The boost in fortunes coincided with extensive touring by the Navan man in Scandinavia, the Baltic States, the US, Australia, New Zealand, Britain, and Ireland.
The firm’s revenues were also boosted in 2011/12 by the Nov 2011 release of Moran’s bestselling DVD, Yeah, Yeah – Live in London, a recording of the stand-up performing at London’s Hammersmith Apollo.
Moran is to embark on a tour of North America next month — last year, he became the first, professional, English-speaking comedian to perform in Russia.
Moran has had a long career in comedy and was the youngest ever winner of the prestigious Perrier award at Edinburgh when he scooped the prize in 1996 at the age of 24.
A career highlight for Moran was the acclaimed Channel 4 comedy series, Black Books, which he co-wrote with Father Ted creator Graham Linehan, winning two Baftas.
The series, which ran between 2000 and 2004, centred around a miserable, unsociable, drunken, and disorganised book shop owner, Bernard Black.
The 41-year-old has also appeared in a number of movies, including Shaun of the Dead, A Cock and Bull Story, and Run Fatboy Run.
Moran is to feature in the upcoming Calvary — the latest film by John Michael McDonagh, writer-director of The Guard.
