MicroPort names Jonathan W. Chen CEO after chairman exits board

Jackson Moreland
Published Oct 25, 2026
Share:
Summary:
  • After the chairman resigned from the board, MicroPort Scientific Corp. named Jonathan W. Chen chief executive officer.
  • Per an Aug. 31 filing, the company's shares and debt in Hong Kong have been halted since Sept. 1 following a postponed mid-year report intended to address audit questions regarding its Shanghai premises.
  • The matter stems from five-year leases that ran out on July 31, 2026, which left 296 million yuan ($44 million) on deposit with landlord Shanghai BlueOrange Capital Corp.; three subsidiaries have renewed through mid-2031, while eight remain in negotiations.

Leadership change and continuity

Jonathan W. Chen took over as CEO following Zhaohua Chang's resignation as director and from other related roles for personal reasons. According to the company, Chang raised no objections regarding the board and is set to remain chief scientific officer.

Trading halt and the lease knot

MicroPort's stock and debt have been on hold in Hong Kong since Sept. 1 while the delayed mid-year report addresses questions tied to its Shanghai premises. The company noted the five-year leases expired on July 31, 2026, with 296 million yuan in deposits still held by Shanghai BlueOrange Capital Corp.

Three subsidiaries have extended their leases to mid-2031. Eight others are still talking terms and deposit refund arrangements and continue to occupy the properties.

When leadership and filings raise questions, stay calmly informed with our free Market Briefs newsletter that explains it simply.

What the board is working through

The board is weighing whether the deposit can be recovered, whether renovation spending was reasonable, and the nature of ties to the landlord. Ownership of the landlord sits with a Hong Kong charity that has no ultimate controllers.

The company plans to reassess its governance framework and tighten its internal rules. It will spell out, in explicit terms, which matters need board approval.

Why investors should watch

In plain English: lease recoverability, governance tightening, and near term debt maturities now frame the risk lens for this name.

Are We in a Recession? 5 Threats to the Economy and Where the Money Is Moving
By Andre Savage
  • The S&P 500 is up about 13% this year, but without AI it's in a bear market, with nearly 40% of its companies down more than 20% for four months or longer.
  • Jackson, Briefs Finance's head of investing research, sees five threats: rising interest rates, sticky inflation, an economy propped up by AI, a struggling UK, and high oil prices.
  • The opportunities he's watching mostly sit outside the dollar: rising economies like Brazil and Indonesia, US-backed emerging market bonds paying 7% to 9%, and the shifts that fear creates.

Common Investing Mistakes: Why a Stock Grade Is One Tool, Not the Whole Toolkit
By Jackson Moreland
  • The Briefs Score shows growth, income, and wealth preservation investors how well a stock fits their goal, with a separate letter grade for each one.
  • The most common mistake is treating the letter as an instruction. An A tells you a stock scores well for one goal, not that you should buy today.
  • Research works best as one input in a process you own. The grade shows how a stock stacks up. You supply the goal, the timeline, and the rules for being wrong.

Is This Stock a Good Buy? How to Use the Briefs Score to Tell If a Stock Fits the Way You Invest
By Nate Gregory
  • The Briefs Score shows growth, income, and wealth preservation investors how well a stock fits their goal, with a separate letter grade for each one.
  • One stock can score very differently for each. Nvidia showed an A- for growth and a D- for income, because it grows fast and pays almost no dividend.
  • Seven sub scores under each grade show what earned the letter, so you can see exactly where a stock is strong or weak for your goal.

How to Tell an Asset From a Liability: The One Question to Ask Before You Buy Anything
By Briefs Finance
  • The typical American household earned more in 2025 than in any year on record, yet only 30% of Americans say they could pay a surprise $1,000 bill from savings, so the problem isn't income but what the income gets spent on.
  • An asset puts money in your pocket and a liability takes money out, and the wealthy buy assets first, then let the assets pay for the fun stuff.
  • Before you buy anything, ask one question: does this put money in my pocket, or take money out of my pocket? Then you need a plan for the money you keep.

How to Build Your First $2,000 Emergency Fund and Wipe Out Every Debt Over 10%
By Briefs Finance
  • Your first money goal isn't investing, it's $2,000 in its own account named Do Not Touch, built by moving 10% of every paycheck into it automatically.
  • More than a third of American adults couldn't cover a $400 surprise bill with cash or savings, according to the Federal Reserve, and that's how one bad day turns into years of credit card payments.
  • Once the $2,000 is there, attack every debt charging more than 10% interest, highest rate first, because you can't out-invest a 22% credit card so paying it off is the investment.
