The company turned over £353.5m in the six months to 30 September 2017, up from £348m for the same period a year ago.
Branded revenue was in line with a year ago, Premier Foods said, at GBP295.4 million, whilst non-branded revenue increased by 10% to GBP57.9 million.
Net debt at the firm was £535.3 million, a £20.7 million improvement on the previous year, the company said.
The group said that it posted a "strong performance" in the second quarter of the year, with more than 40% of revenue growth in this period from its global strategic partnerships with Nissan and Mondelez.
The results come despite a "challenging" first quarter for Premier Foods.
"The cost efficiency programme we launched earlier this year is on track to deliver the expected benefits", said Darby.
The British food manufacturer also extended the geographic reach of the licensing agreement with Mondelēz to 46 countries, including the UK, Ireland, Australasia, United Arab Emirates, South Africa, Canada, Japan, China, India, Asia Pacific, Caribbean and additional countries in the Middle East. We completed the issue of a new GBP210 million high yield bond in June and our net debt was GBP21 million lower than the same point previous year; a little ahead of our plans. "Overall, we continue to expect the business to make progress in the second half of the year and our expectations for the full year remain unchanged".
Oxo and Bisto owner Premier Foods returned to growth in the 26 weeks to 30 September, driven by fast growth in convenience foods such as Batchelor's noodles and pasta.
Shares in Premier Foods were up 4.8% at 38.25 pence on Wednesday.
"In fact we are happy to pat management on the back for the trading performance in Q2, a performance that may help support the mood music around the shares today".
