What a difference a day makes for Core Lithium Ltd (ASX: CXO) shareholders.
After jumping 12% yesterday, the lithium miner has gone backwards on Thursday, falling 7.74% to 38.8 cents in morning trade.
The selling follows a string of company announcements released this morning, giving investors plenty to digest after the stock's recent rally.
Despite today's decline, Core shares have still gained approximately 269% over the past year following a remarkable recovery.
So, let's take a closer look at what's going on with Core Lithium?

Cash piles up, but losses continue
Core's FY26 annual report shows a significant improvement in the company's financial position, although there's still some work to do.
The lithium miner finished June with $181.8 million in cash, compared with just $23.5 million a year earlier.
Much of that improvement came from a $120 million share placement and funding arrangements with Glencore and InfraVia.
However, Core still reported a net loss of approximately $26 million, while operating cash outflows totalled $21.1 million.
The company also received approximately $62.2 million in additional funding after the financial year ended.
Finniss is back in business
The good news is that Core's flagship Finniss lithium operation is making progress following its restart.
Earlier this month, the company produced its first spodumene concentrate from the processing plant, meeting its September quarter target.
According to the release, the milestone was achieved within 6 months of the final investment decision (FID) in March.
Core has also completed upgrades to the processing plant, which are expected to increase annual throughput capacity by approximately 20% to 1.2 million tonnes.
Meanwhile, development continues at the BP33 underground mine, with first ore targeted for mid 2027.
The next milestone will be the first shipment of newly produced lithium concentrate, which Core expects during the December quarter.
What's behind Thursday's sell-off?
While the annual report contains some encouraging developments, lithium prices have been heading in the opposite direction of late.
According to Trading Economics, lithium carbonate was trading at approximately 135,200 Chinese yuan per tonne on Wednesday.
This is down 15.76% over the past month.
The recent pullback comes as more Aussie lithium mines return to production, with investors keeping a close eye on the potential increase in supply.
Following Core's recent share price rally, some investors may also be taking the opportunity to lock in profits.
I think Core Lithium's next test is getting Finniss running consistently and generating cash, particularly with lithium prices below their recent highs.
