Tesla’s $218M acquisition of ultracapacitor firm opens doors to energy breakthroughs
Just a few days after Tesla (NASDAQ:TSLA) posted its second consecutive profitable quarter, the company has stated that it plans to acquire energy technology firm Maxwell Technologies, a California-based maker of ultracapacitors and batteries. The deal will reportedly be an all-stock transaction valued at around $218 million, with Tesla buying Maxwell’s 45.9 million shares for $4.75 a share — a 55% premium over the energy company’s closing price of $3.07 a share last Friday.
Maxwell Technologies specializes in the development of ultracapacitors. Prior to its acquisition by Tesla, Maxwell had been working on developing dry electrode technologies that could be utilized to create ultracapacitors that can store large amounts of electrical charge without losing energy — a breakthrough for electric cars and energy storage devices. Ultracapacitors are lauded by several industry watchers as a possible alternative to today’s batteries, considering their potential to be safer and more reliable.
In a statement to The Street, Maxwell Technologies CEO Dr. Franz Fink expressed his optimism over the planned acquisition. The CEO further pointed out that Tesla and Maxwell actually share a common goal — to build a more sustainable future.

“We are very excited with today’s announcement that Tesla has agreed to acquire Maxwell. Tesla is a well-respected and world-class innovator that shares a common goal of building a more sustainable future. We believe this transaction is in the best interests of Maxwell stockholders and offers investors the opportunity to participate in Tesla’s mission of accelerating the advent of sustainable transport and energy,” he said.
Dr. Fink’s statement was echoed by Tesla. In a statement to CNBC, the electric car maker noted that it is always on the lookout for possible acquisitions that would allow it to pursue its mission. “We are always looking for potential acquisitions that make sense for the business and support Tesla’s mission to accelerate the world’s transition to sustainable energy,” Tesla noted in a statement sent to the publication.
What is particularly interesting about Maxwell’s acquisition is that Elon Musk himself has expressed his support for ultracapacitor technologies in the past. Back in 2013, Musk mentioned on a Twitter post that he is a “big fan of ultracapacitors,” even adding that he was planning on conducting his Ph.D. research on ultracapacitors during his short stint at Stanford University. That said, Musk also noted that there needs to be a breakthrough in energy density for ultracapacitors to truly make a difference.
@yes_andre I'm a big fan of ultracapacitors. Was going to do my PhD at Stanford on them. But we need a breakthrough in energy density…

Tesla’s acquisition of Maxwell Technologies marks the electric car maker’s fifth acquisition to date. Prior to Maxwell, Tesla acquired Riviera Tool LLC, a manufacturer of stamping die systems used to form sheet metal parts in May 2015; SolarCity, a provider of solar energy services to homeowners, businesses, government, and non-profit organizations in June 2016; Grohmann Engineering, a firm that makes Tesla’s robots for production in November 2016; and Perbix, a maker of highly automated manufacturing equipment in November 2017.
Tesla and Maxwell Technologies expect to close the acquisition deal sometime in the second quarter of 2019, pending customary closing conditions. So far, the deal appears to be well received by Maxwell’s investors, with the company’s stock (NASDAQ: MXWL) trading up 50.49% as of writing. The reaction of the market to Tesla appears to be more muted, with TSLA stock trading down 0.52% as of writing.

Elon Musk breaks his silence on the Starlink impact to Ukraine drones
Musk says the US military and president set Starshield limits, not SpaceX, amid Ukraine complaints.
Elon Musk says the speed limit cutting out Ukraine’s military Starlink terminals is not SpaceX’s decision. In a post on X Wednesday, Musk wrote that “Starshield systems are owned and controlled by the US government. Any limits on speed or usage are decided by the US military and ultimately POTUS.” He added that Starlink is a commercial service limited to civilian or defensive activities and “cannot be used for offensive military action, as doing so would be inappropriate for a commercial company.”
He was replying to Mykhailo Fedorov, Ukraine’s former defense minister, who had thanked Musk for restoring connectivity at speeds up to 160 km/h and said removing the Starshield limit entirely is “now critical for Ukraine’s defense.”

The complaint started Tuesday night, when Ukrainian officials said military terminals began losing service above roughly 100 mph. Presidential adviser Serhiy Beskrestnov said the defense forces got no warning and several missions were disrupted, as Teslarati reported earlier Wednesday. The 7th Rapid Reaction Corps told Reuters connections dropped for 10 to 20 seconds at speeds well below the limit, which made drones harder to control. Poland’s foreign minister, Radoslaw Sikorski, asked Musk on X whether he is “playing politics with your products again.”
That is why the Starlink and Starshield distinction matters. SpaceX introduced Starshield in 2022 as the government version of Starlink, with an initial focus on Earth observation, communications and hosted payloads. It won a Space Force contract in 2023 with a $70 million ceiling. In December 2024, the Pentagon moved Ukraine’s terminals onto Starshield, covering about 3,000 units across two contracts. Ukraine’s military connections therefore run through a service that Musk now says sits under Washington’s control.
While Musk’s post describes who holds authority, it does not infer that anyone ordered the limit, and neither SpaceX nor the US government has confirmed who set it. Ukrainian officials have pointed to the timing, which follows President Trump’s push for an energy ceasefire and Musk’s Saturday post that “Zelensky has gone too far.” The BBC noted Trump denied threatening to restrict intelligence sharing with Kyiv, and no evidence has been presented that Washington requested the cap.
The episode also revives a promise from 2025. After Poland accused him of threatening Ukraine’s access, Musk said Starlink “will never turn off its terminals” and would not be used as a bargaining chip. Poland has since supplied more than 29,000 terminals to Ukraine. Teslarati also covered Kyiv’s search for Starlink alternatives in 2025, and the latest dispute gives that search new urgency.

Tesla opens the Q&A for its biggest earnings call yet
Tesla opens its Q3 earnings Q&A, and Cybercab, Robotaxi, Optimus and regulators loom over October 21.
Tesla has opened its shareholder question portal for the Q3 2026 earnings call, with the Say Q&A page already listing questions. Investors have until 4:00 p.m. EDT on October 20 to submit and vote on what management should answer.
The call is set for Wednesday, October 21. Tesla will post results after the market closes, with a live webcast at 4:30 p.m. CT, or 5:30 p.m. ET, through its investor relations site.
Say ranks questions by the number of shares behind the votes, which gives institutional holders extra weight over the retail crowd.
Ahead of Q2, retail investors asked why Robotaxi growth had stalled, when Cybercab would start customer rides, and where the Optimus Gen 3 ramp stood, while an institutional holder asked how Tesla and SpaceX would split Terafab duties. Cybercab has since answered one of those. Tesla said last week it has 300 plus Cybercabs serving Austin, up eightfold in 30 days, with Dallas named as the next city. The questions now are likely to move from when to how fast.
There is also a regulatory question hanging over the call. NHTSA has demanded sworn answers on how the pedal free Cybercab was certified against federal safety standards, with responses due October 30, nine days after the call. Whether an analyst raises it live is unknown, but it is the kind of exposure that tends to find its way into a Q&A.
The numbers will not be the main draw. Tesla already reported 486,532 deliveries and 13.7 GWh of storage for the quarter. Consensus sits around 43 to 45 cents per share on roughly $27.8 billion in revenue, according to Zacks, after a Q2 report that missed on EPS. Goldman Sachs, which holds a Neutral rating and a $360 target, argues the outlook for Robotaxi, FSD and Optimus will matter more to the stock than the quarter itself.
The call also lands six days after the rescheduled Roadster event, which Tesla will stream on X on Thursday, October 15, at 7:55 p.m. CT. If the Roadster shows up with a production date or a SpaceX thruster package, expect it to climb the voting list before the deadline.

FAA kicks off review of SpaceX’s bid to fly Starship nearly every day
FAA is reviewing SpaceX’s plan for 456 Starship launches a year, up from 25 today.
The FAA said Tuesday that it will prepare an environmental impact statement on SpaceX’s proposal to run as many as 456 Starship launches and 912 landings a year from Starbase, Texas. SpaceX is currently authorized for 25 launches and 50 landings annually, which makes the request roughly 18 times the existing ceiling. The notice of intent is set to publish in the Federal Register on Wednesday.
The plan comes in two phases. Phase 1 would allow up to 100 launches and 200 landings a year, on any day and at any hour. Phase 2, which the FAA says could arrive within several years, would raise the limit to the full 456 launches, still at any hour but only on weekdays. The agency noted that 912 landings is the upper limit for the Texas facility no matter where a given mission begins, and that Starship and Super Heavy could come down at the launch site or in the Gulf and open ocean.
A draft statement will be released for public comment at a later date, and the FAA has not said when. According to the Federal Registar, written comments are due November 30 on regulations.gov under docket FAA-2026-12808, with in person scoping meetings on November 17 in Brownsville and November 19 in Port Isabel, plus a virtual session on November 18. The review will weigh air quality, wildlife, coastal resources, water, noise, and aviation, and the FAA said any increase beyond this proposal would need its own separate review.
The numbers look large next to what Starbase has actually done. Starship has flown three times from Texas this year, including Flight 14 on September 28, the first orbital flight, which deployed 26 Starlink V3 satellites. Bloomberg reported that Starbase has never launched more than five times in a calendar year. The current cap of 25 comes from an FAA approval in May 2025. In February, the agency also approved up to 44 Starship launches a year from Launch Complex 39A in Florida, so Phase 1 in Texas alone would more than double that allowance.
Musk has said Starship could eventually fly more than once per hour within less than a decade, per Bloomberg. The nearer term target is Flight 15. Musk said on October 10 that it is hopefully four to six weeks away and will try to catch the ship with the tower, as Teslarati covered. That flight still runs under the existing 25 launch limit, and so would every Starbase launch for as long as the new review takes.
As of mid morning Pacific time on Tuesday, SpaceX had not posted about the filing on its own account.
