AMS AG said a week ago it did not see "sufficient basis" for continuing its discussions with the German technology company, after approaching Osram to discuss a non-binding takeover offer of 38.50 euros ($43.08) per share, sparking a potential bidding war for the German company.
However, the Swiss-listed sensor specialist said on Tuesday it had been approached by potential financial partners and had exchanged views "which confirm its belief that AMS can arrange prudent and committed financing for this potential transaction."
AMS' shares were up around 9% in early trading.
Osram, which is grappling with weakness in the automotive industry and a broader economic slowdown, had sparked bidding interest because of its potential as a supplier for connected and autonomous cars.
AMS aims to expand with super-fast and power-effective laser diodes that are used for light detection and ranging in self-driving cars - so-called VCSELs for automotive Lidar systems.
AMS, which supplies Apple with sensors for its face recognition technology and suffered from lower than expected demand for the latest iPhones late last year, said demand had continued to recover in the second quarter, with revenues rising to $415.2 million, in the upper half of its $390-430 million guidance.
It expects third-quarter revenue to reach $600-640 million.
AMS posted adjusted earnings before interest and tax of $50 million for the second quarter and said high volume ramps in the consumer market and a better operational performance should lead to an adjusted operating margin of above 25% in the third quarter.
