Adobe Systems is planning large numbers of redundancies following its $3.4bn (£2bn) completed acquisition of Macromedia.
The acquisition was announced in spring but was only completed last weekend. Adobe now says job cuts will be announced on 15 December, when it delivers its annual financial results.
The cuts will mainly be made where job duplication exists between the companies, said Adobe. Some staff will also be offered job re-location packages.
Macromedia had 1,500 employees worldwide before the acquisition, with around 350 of them outside the US. Adobe said cuts would also affect Adobe staff.
The acquisition has enabled Adobe to add Macromedia’s popular Flash animation and video products to its own portfolio, which includes the widely used Adobe Reader for viewing documents in Adobe’s Portable Document Format (PDF).
The expanded product line, which now numbers around 70 products, is seen by analysts as potentially increased competition to Microsoft’s desktop software range.
