Restructuring investment banking (RX) advises distressed companies and their creditors when an over-leveraged capital structure can no longer be serviced. Per Wall Street Prep, RX bankers step in when "capital structure issues arise" from companies with "insufficient liquidity to meet their obligations," and they work either the debtor side (the struggling company) or the creditor side (bondholders and lenders). The work spans out-of-court amendments, distressed exchanges, and in-court Chapter 11 reorganizations. RX is countercyclical: Wall Street Prep notes deal count "increases during macroeconomic contractions and decreases during expansionary phases." This guide covers what RX does, debtor versus creditor mandates, why it thrives in downturns, and the RX-specific interview topics.

TL;DR

  • RX advises distressed companies (debtors) or their lenders (creditors) on fixing an over-leveraged capital structure.
  • Demand is countercyclical: deal count rises in recessions and falls in expansions, per Wall Street Prep.
  • Solutions run from out-of-court amend-and-extend deals to in-court Chapter 11 reorganizations.
  • The fulcrum security is the capital-structure layer that "breaks" at the enterprise value, the core RX concept.
  • Top RX shops are boutiques: Houlihan Lokey, PJT, Evercore, Moelis, Lazard, and Perella Weinberg.

What does RX mean in finance?

RX is the standard abbreviation for restructuring, in the same way M&A abbreviates mergers and acquisitions. On a bank's website and in recruiting it appears as "RX", "Restructuring", or "Restructuring and Special Situations", and all three name the same group. "RX banking" and "RX IB" are the same thing: the restructuring group inside an investment bank. The two-letter form comes from the medical prescription symbol and is used because it is faster to type on a deal team, not because it carries any separate technical meaning.

What is restructuring investment banking?

Restructuring investment banking advises companies (debtors) on modifying their capital structures to survive, and also advises creditors seeking the best recovery. Mergers and Inquisitions defines RX bankers as those who advise on "deals to modify their capital structures for survival" and work on "bankruptcies, liquidations, and distressed sales." The trigger is almost always too much debt and too little cash.

RX sorts troubled companies into three states. A "stressed" company still pays interest but faces a looming maturity wall or cash crunch. A "distressed" company has already defaulted on interest or principal or broken a covenant. A "bankrupt" company has filed Chapter 7 (liquidation) or Chapter 11 (reorganization). The banker's job changes with the state: rightsize the balance sheet before a default, negotiate recoveries during one, or value assets in a liquidation. Restructuring uniquely blends "psychology, finance, and law," per restructuringinterviews.com, because every deal turns on creditor negotiation and bankruptcy code as much as on the model. Understanding the leverage that gets a company here starts with coverage ratio vs leverage ratio, and separating a liquidity problem from a solvency problem is the first diagnosis in liquidity vs solvency and the signs of distress.

What is the difference between debtor and creditor mandates?

RX banks take one of two sides. On a debtor mandate, the bank represents the struggling company and works to maximize its value and forge a viable plan of reorganization. On a creditor mandate, the bank advises bondholders or lenders and works to maximize their recovery. A single debtor usually hires one advisor; creditors often band together into committees with their own advisors. The week-by-week work inside either mandate is mapped in what a restructuring adviser does on a deal.

Mergers and Inquisitions compares debtor-side work to sell-side M&A (you tell the recovery story and run the process) and creditor-side work to buy-side diligence (you scrutinize the plan and push for better terms). Wall Street Prep states the debtor-side objective is "to maximize the value of the company," while the creditor side aims "to maximize creditor recoveries/value." Debtor mandates are proactive and pay higher fees; creditor mandates are reactive, reviewing a proposed solution. The conflict between the two sides is the heart of every restructuring, and it is why interviewers test which side you understand. The same banks that lead RX often top the M&A boutique tables, like Evercore and Moelis.

Why is restructuring countercyclical?

RX is countercyclical because distress rises when the economy falls. When recessions hit and credit tightens, over-leveraged companies cannot refinance, defaults climb, and RX mandates surge. When the economy expands and money is cheap, fewer companies are distressed, deal volume drops, and bankers may be reassigned to other groups.

This is the defining feature that separates RX from M&A, which booms in good times. Wall Street Prep notes demand "increases during macroeconomic contractions and decreases during expansionary phases." The pattern showed clearly in 2020: restructuringinterviews.com reports consumer-discretionary filings dominated the bankruptcy wave, and the reversal was just as sharp when CCC-rated issuance roughly doubled year-over-year in the 2020-2021 risk-on credit boom that followed. The countercyclical nature also makes compensation cyclical: Mergers and Inquisitions notes senior RX bankers "may experience years of modest bonuses followed by windfall years during recessions." For candidates, the upside is that RX hiring can stay strong precisely when the rest of banking slows.

What are the key RX interview topics?

RX interviews layer restructuring-specific concepts on top of standard banking technicals. Beyond accounting, valuation, and LBOs, you must understand the recovery waterfall, the fulcrum security, distressed valuation, Chapter 7 versus Chapter 11, DIP financing, and out-of-court versus in-court tradeoffs. Interviewers also expect a sharp "why restructuring?" answer, so the dedicated restructuring interview questions set is worth working through.

The recovery waterfall ranks creditors by seniority and pays them in order until value runs out. Wall Street Prep gives the canonical setup: a company with 200 million dollars of EBITDA sold at 5x equals 1 billion dollars of enterprise value, against a 100 million dollar revolver, a 200 million dollar Term Loan A, and 1 billion dollars of unsecured senior notes. The fulcrum security is the layer that "matches up with the theoretical enterprise value," meaning it is partially covered and converts to equity in a reorganization. Liquidation analysis applies recovery factors by asset: cash near 100%, receivables 60-80%, goodwill 0%. You should also know in-court tools (Chapter 11, DIP financing, the automatic stay) versus out-of-court deals (amend-and-extend and distressed exchanges, tender offers), which protect existing equity but offer less leverage. Because LBO mechanics underpin recovery and going-concern valuation, master walk me through an LBO before any RX interview.

Run the waterfall: a company with 200 million dollars of EBITDA is worth 1 billion dollars at a 5x multiple, against a 100 million dollar revolver, a 200 million dollar term loan, and 1 billion dollars of senior unsecured notes. Where does the money run out and which class is the fulcrum?

Explain the difference between Chapter 11 and Chapter 7, and why creditors usually prefer Chapter 11.

Which firms lead restructuring investment banking?

RX is dominated by elite boutiques, not bulge brackets. Bulge brackets have minimal presence because of conflicts of interest (they often hold the distressed company's debt) and reputational concerns. The leaders are independent advisory firms built around restructuring and M&A.

A 2022 league table cited by restructuringinterviews.com ranks the top RX shops by engagements: Houlihan Lokey (30), PJT (29), Evercore (26), Moelis (17), and Perella Weinberg (16), with Lazard also in Tier 1. Wall Street Prep lists the same Tier-1 group: Houlihan Lokey, PJT Partners, Perella Weinberg, Lazard, Evercore, and Moelis. Houlihan Lokey is the most prolific debtor and creditor advisor and is the namesake of the "Houlihan Lokey distressed case study" that RX candidates are expected to know. RX exits are strong for the buy side: Wall Street Prep notes RX analysts are "first in line for credit funds and distressed debt/special situation shops" and competitive for private equity and hedge funds, because the credit, valuation, and process skills transfer directly.

Quick Math

  1. A bond pays a $6 coupon and trades at $80. What is its current yield, in percent?

    Current yield = coupon ÷ price, not the coupon rate.

  2. EBITDA is $120 million and interest expense is $30 million. What is interest coverage, as a multiple?

    Coverage = EBITDA ÷ interest.

  3. At a 10% discount rate, roughly what is $100 million received in 2 years worth today, in millions?

    The 2-year discount factor at 10% is 1 ÷ 1.1², about 0.83.

Frequently Asked Questions

What does a restructuring investment banker do?

A restructuring banker advises a distressed company or its creditors on fixing an unsustainable capital structure. The work includes building liquidity and recovery analyses, negotiating amend-and-extend deals or distressed exchanges, arranging DIP financing, and advising through Chapter 11 reorganizations or asset sales. The goal is to maximize value for whichever side the bank represents.

Is restructuring better than M&A for exit opportunities?

RX is especially strong for credit-focused buy-side exits. Wall Street Prep notes RX analysts are "first in line for credit funds and distressed debt/special situation shops" and remain competitive for private equity and hedge funds. The capital-structure, valuation, and negotiation skills transfer well, though traditional buyout firms still recruit heavily from M&A and industry groups too.

What is the fulcrum security in restructuring?

The fulcrum security is the layer in the capital structure that "breaks" at the company's enterprise value, meaning it is the most senior claim that is only partially repaid. In a reorganization, the fulcrum holders typically convert their debt into the new equity of the restructured company, so identifying it is central to every RX analysis.

Why is restructuring countercyclical?

Restructuring demand rises when the economy weakens. In recessions, over-leveraged companies cannot refinance, defaults increase, and RX mandates surge. In expansions, cheap credit keeps companies solvent and deal volume falls. Wall Street Prep confirms RX deal count "increases during macroeconomic contractions and decreases during expansionary phases," the opposite of M&A.

What is the difference between in-court and out-of-court restructuring?

Out-of-court restructuring renegotiates debt without a bankruptcy filing, which is cheaper, faster, quieter, and can protect existing equity, but gives the company less negotiating leverage. In-court restructuring (Chapter 11) provides legal tools like the automatic stay and contract rejection, but is more expensive, public, and usually wipes out pre-filing equity.

Which firms are best for restructuring investment banking?

The top RX firms are boutiques: Houlihan Lokey, PJT, Evercore, Moelis, Lazard, and Perella Weinberg. A 2022 league table ranks Houlihan Lokey first by engagements, followed by PJT, Evercore, Moelis, and Perella Weinberg. Bulge brackets play a limited role because of conflicts of interest with the distressed debt they often hold.
