Research In Motion Ltd reported a narrower than expected loss on Thursday and the struggling BlackBerry maker bolstered its cash reserves, sparking optimism ahead of the launch of its make-or-break line of next-generation smartphones.

Shares of RIM surged 20 per cent in after-hours trade on indications the company will have plenty of cash to ramp up production of its new BlackBerry 10 devices and mount a robust marketing campaign for the revamped line, due in early 2013.

It was the biggest jump for the stock since a 50 per cent surge in December 2003, underlining the importance of the BB10 launch.

The company, which has fallen far behind its rivals in a smartphone market it once dominated, has staked its future on the BB10 and its completely redesigned operating system.

RIM's second fiscal quarter brought shareholders additional glimmers of hope, a break from a succession of dreadful quarterly reports.

The company not only generated more revenue than Wall Street had forecast but it topped expectations on the number of devices shipped in the period, which ended on September 1.

"It's very impressive," said Jefferies & Co analyst Peter Misek. "I didn't expect they could execute on the business given the models they have in the market, but they obviously did really well in emerging markets."

RIM was also able to bolster its cash pile by collecting on cash owed to the company, drawing down inventories and cutting costs.

ONE-TIME PIONEER

A one-time smartphone pioneer, RIM has failed to keep pace with rivals such as Apple Inc and Samsung Electronics Co, and its stock price has tumbled about 70 per cent over the past year while its market share shriveled.

But the latest quarter showed that RIM is still able to lure buyers for its lower-end smartphones in the more price-conscious emerging markets.

And that has helped make up for ground the BlackBerry has lost to cutting-edge devices such as Apple's iPhone and Samsung's Galaxy S III in North America and Europe.

"RIM and its products, however obsolescent, are still relevant in the parts of the planet where most people live," said CCS Insight analyst John Jackson.

"The bad news is that these results have little or no bearing on what remains true, and that is, RIM still needs to execute on BB10."

In an attempt to create a buzz, chief executive Thorsten Heins gave a preview of the new smartphone and its features to app developers at an event on Tuesday in San Jose, California.

Analysts said RIM struck the right chords at the event but cautioned that it is hard to evaluate how well the BB10 devices will work in real world conditions until they are on the market.

"We are now just a few months away from our launch and our teams are working night and day to meet the expectations we have of ourselves," said Heins on a conference call after the results were released on Thursday.

Heins said RIM executives have met with dozens of carriers in more than 16 countries in the last few weeks and the feedback on the new devices so far has been overwhelmingly positive.

QUARTERLY RESULTS

Shipments of BlackBerry smartphones were 7.4 million in the quarter, easily outpacing Wall Street's expectation of about 6.9 million.

The Waterloo, Ontario-based company reported a net loss of $235 million, or 45 cents a share, in its fiscal second quarter. That compared with a profit of $329 million, or 63 cents, in the same period a year earlier.

Excluding one-time restructuring-related items, the loss came in at $142 million, or 27 cents a share, in the quarter just ended.

Revenue rose to $2.9 billion, a gain of 2 per cent from the fiscal first quarter, but the latest result was down about 30 percent from the same period a year earlier.

Analysts, on average, had expected RIM to report a loss of 46 cents a share, on revenues of $2.5 billion, according to Thomson Reuters I/B/E/S.

"You still have revenue declining 31 percent on a year-over-year basis but it's certainly not the train wreck that a lot of people feared," said BGC Partners analyst Colin Gillis. "They live to fight another day."

CASH PILE

RIM also increased its cash to about $2.3 billion from $2.2 billion in the fiscal first quarter.

"In the last two quarters RIM has done a really good job on collecting on receivables," said Sterne Agee analyst Shaw Wu, but he cautioned that this was not sustainable over the long run and RIM would have to return to a profitable business model for it to thrive once again.

While RIM has warned that it faces another operating loss in its fiscal third quarter, it expects its cash position to remain stable unless it is hit by restructuring charges.

Wu believes that the company can achieve this by continuing to draw down on its receivables, which stood just shy of $2.2 billion as of Sept 1.

RIM's chief financial officer said the company had entered into a new secured credit facility of $500 million which expires in September 2013, and in the first half RIM realised some $350 million of the up to $1 billion in cost savings it hopes to achieve in fiscal 2013, which ends on March 2 of next year.

The company, which earlier this year said it would cut about 5,000 jobs to save money, said it has already laid off roughly 2,500 workers.

"It's still bad, but it's a much smaller disaster than expected," said Wu. "These stocks all trade on expectations. Expectations were really low, and they were able to beat that."

RIM's US-listed shares surged 20 per cent to $8.55 in trade after the closing bell on Thursday.
